CROSS-REFERENCE TO RELATED APPLICATIONS
TECHNOLOGICAL FIELD
[0002] The technological field generally relates to luggage, and more particularly to luggage
with multi-opening zipper configurations and detachable transport systems for luggage.
BACKGROUND
[0003] Luggage pieces are generally utilized by travelers to pack and transport items.
[0004] Regarding packing or unpacking items, some luggage pieces, such as duffel bags, have
substantially linear zippers , which allow a user to access the compartment of the
luggage piece to pack and unpack items. However, a linear zipper sometimes makes it
difficult for large or wide items to pass through the opening formed in the luggage
using the zipper. In addition, the opening created by the linear zipper often does
not offer a user a good view of the inside of the luggage piece, thus making it difficult
for a user to pack the items neatly or to find an item contained therein.
[0005] Regarding transporting the luggage piece and the items contained therein, lifting
and carrying the luggage piece may be cumbersome or difficult for some. Many luggage
pieces include wheels and a handle to enable rolling transport of the luggage piece.
Generally, the wheels and the handle may be non-detachably joined to the luggage piece
such as by fastening with rivets or by sewing, welding, adhering, and combinations
thereof. In some cases, the wheels and the handle may be unnecessary or undesirable
for transporting the luggage piece. In addition, the wheels and handle may generally
add rigidity to the luggage piece making storage of the luggage piece difficult.
[0006] Some approaches to configuring and/or transporting luggage are shown in the following
documents:

WO03053186,
WO2004080230, and
WO2006083633. These proposals, however, may be improved.
[0007] Regarding opening configurations for luggage pieces, some references suggest using
multiple zippers to create a relatively large non-linear shaped opening. These approaches,
however, may lack proper securement of the various portions of the luggage piece that
are zipped together by the multiple zippers. Without proper securement, when the opening
is closed by the zippers, the load contained within the luggage may force at least
some of the zippers to undesirably move towards their open configuration, thus resulting
in an undesirable sudden opening of the luggage piece that exposes the items contained
therein.
[0008] Regarding transporting luggage pieces, although some references suggest the possibility
of using a wheel assembly that could be temporarily joined to and removed from the
luggage piece, such assembly is usually rigid and/or cumbersome, which may make the
luggage piece that is joined to the wheel assembly difficult to maneuver. In addition,
such assembly and the luggage piece are typically joined at certain discrete locations
(e.g., along certain edge portions) of the luggage piece, thus requiring multiple
joining operations by a user to secure the luggage piece to the wheel assembly but
not necessarily providing a secure attachment between the two. Further, due to its
rigidity, extra space may be required for storage of such assembly. Moreover, the
frame or handle structures in the existing assembly are often exposed, resulting in
potential scuffing or other damage to the handle structures. Moreover, the existing
assemblies often lack a desirable aesthetic appearance, thus potentially reducing
a consumer's interest in using the wheel assembly with a piece of luggage.
[0009] It is therefore desirable to provide an improved luggage configuration and/or a transport
system or device thereof that address the above described problems and/or that more
generally offer improvements or an alternative to existing arrangements.
SUMMARY
[0010] Described herein are luggage items, transport systems or devices for the luggage
items, and luggage assemblies including a luggage item and a transport system or device.
[0011] The transport systems or devices may include wheels and a handle. The transport systems
or devices may be detachably joined to luggage pieces and may be utilized to transport
luggage pieces by rolling transport. The transport systems or devices may be used
with a number of luggage pieces including duffel bags, soft sided luggage, hard sided
luggage, and the like. When detached from the luggage pieces, the transport systems
or devices may be stored separately from the luggage pieces and the luggage pieces
may be used alone. In some implementations, the transport systems or devices may be
collapsed such as for storage or for manual transport.
[0012] In one implementation of the luggage assembly, the luggage assembly may include a
luggage item and a transport device. The luggage item may include a releasable attachment
member provided on the luggage item. The transport device may include a body, a retractable
handle joined to the body, and one or more wheels joined to the body. The transport
device may further include a releasable attachment member complementary to the releasable
attachment member provided on the luggage item. The releasable attachment member of
the transport device may be positioned along a substantial portion of a periphery
of the body. The releasable attachment member of the transport device may be configured
to releasably engage the releasable attachment member provided on the luggage item
in order to selectively join the luggage item to the transport device.
[0013] In some implementations, the body of the transport device may be relatively flexible.
[0014] In some implementations, the releasable attachment member of the transport device
may include a single continuous member positioned along the substantial portion of
the periphery of the body.

bottom side overlapped may include no less than 20%, preferably no less than 50%,
more preferably no less than 80% of a surface area of the bottom side of the luggage
item.
[0022] In some implementations, the upper region may be configured to be coextensive with
the top side of the luggage item along at least one of a depth dimension or a width
or transverse dimension of the top side.
[0023] In some examples, the upper region may be configured to be coextensive with a depth
dimension of the luggage item measured from a front side to a back side of the luggage
item.
[0024] In some implementations, the lower region may be configured to be coextensive with
the bottom side of the luggage item along at least one of a depth dimension or a width
or a transverse dimension of the bottom side.
[0025] In some examples, the lower region may be configured to be coextensive with a depth
dimension of the luggage item measured from a front side to a back side of the luggage
item.
[0026] In some implementations, a central portion of the body may be narrower than at least
one of upper and lower end portions of the body.
[0027] In some implementations, the upper, middle and lower regions of the body may extend
along a longitudinal dimension of the body. At least one of the upper or lower region
may define a transverse dimension larger than a transverse dimension of the middle
region.
[0028] In some implementations, the retractable handle may further include a pivot joint
assembly. The pivot joint assembly may be configured to pivot to enable the detachable
transport device to fold at the middle region of the body.
[0029] In some implementations, the body may further include a support member mounted to
the lower region of the body. The support member may be configured to be extendable
along a surface of the lower region upon which the support member is mounted to support
the luggage item when the luggage item is configured in an upright position.
[0030] In some implementations, at least a portion of the periphery of the body may include
in general a curvilinear shape.
[0031] In some implementations, at least a portion of the body may include in general an
hourglass shape.
[0032] In some implementations, the body may further include a front panel and a rear panel
defining an internal compartment of the body. A portion of the retractable handle
may be received within the internal compartment of the body.
[0033] In some implementations, the body may further include a closure mechanism joined
to the front panel for selectively exposing the internal compartment of the body.
[0034] In some implementations, the releasable attachment member of the body and the complementary
releasable attachment member on the luggage item may collectively take the form of
at least one of a zipper mechanism, a hook-and-loop closure mechanism, or a snap closure
mechanism.
[0035] In some implementations, the luggage item may include one or more materials defining
an internal compartment of the luggage item. The internal compartment of the luggage
item may be selectively accessed through an X-shaped opening defined by selective
movement of first and second portions of the one or more materials relative to other
portions of the one or more materials. The first and second portions may each terminate
proximate to a center of the X-shape.
[0036] In one implementation of a luggage item, the luggage item may include one or more
materials defining an internal compartment of the luggage item. The internal compartment
of the luggage item may be selectively accessed through an X-shaped opening defined
by selective movement of first and second portions of the one or more materials relative
to other portions of the one or more materials. The first and second portions may
each terminate proximate to a center of the X-shape. The luggage item may further
include two or more closure mechanisms operatively joined to the one or more materials.
The two or more closure mechanisms may be configured to selectively couple and uncouple
the first and second portions of the one or more materials to the other portions of
the one or more materials in order to selectively close and open the X-shaped opening.
The luggage item may also include a securing mechanism. The securing mechanism may
be configured to releasably secure the first and second portions of the one or more
materials to each other regardless of whether or not the other portions of the one
or more materials are coupled to or uncoupled from the first and second portions of
the one or more materials.
[0037] In some implementations, the securing mechanism may include at least one of a hook-and-loop
closure mechanism or a snap closure mechanism.
[0038] In some implementations, the luggage item may further include a releasable attachment
member for selectively joining the luggage item to a complementary releasable attachment
member of a transport device.
[0039] In some implementations, the releasable attachment member of the luggage item may
surround or encompass or enclose an area across three continuous sides of the luggage
item.
[0040] In some implementations, the releasable attachment member of the luggage item may
include a single continuous member.
[0041] In one implementation of a detachable transport system, the detachable transport
system for a luggage piece may include a flexible or soft sided body with an hourglass
shape, and a releasable attachment member may extend along an outer periphery of the
flexible or soft sided body. A retractable handle may be provided on an upper region
of the flexible or soft sided body, and one or more wheels may be provided on a lower
region of the flexible or soft sided body. The releasable attachment member may releasably
join with a complementary releasable attachment member provided on the luggage piece
to enable the retractable handle and the one or more wheels to be used to transport
the luggage piece and the detachable transport system.
[0042] In some implementations, the hourglass shape of the flexible or soft sided body may
include a relatively narrower middle region.
[0043] In some implementations, the releasable attachment member may substantially extend
around an entire circumference of the outer periphery of the hourglass shaped flexible
or soft sided body.
[0044] In some implementations, the retractable handle may further include a pivot joint
assembly. The pivot joint assembly may be arranged within the flexible or soft sided
body. The pivot joint assembly may be configured to pivot to enable the detachable
transport system to fold at a middle region of the flexible or soft sided body between
the upper and lower regions.
[0045] In some implementations, the pivot joint assembly may further include a telescoping
member joined to the handle. As the pivot joint assembly pivots, the telescoping member
may be configured to telescope into the pivot joint assembly and to retract the handle.
[0046] In another implementation of a luggage transport system, the luggage transport system
may include a detachable transport system and a luggage piece. The detachable transport
system may include a flexible or soft sided body with a contoured shape. A releasable
attachment member may extend along an outer periphery of the flexible or soft sided
body. A retractable handle may be provided on an upper region of the flexible or soft
sided body, and one or more wheels may be provided on a lower region of the flexible
or soft sided body. The luggage piece may include a flexible or soft sided enclosure
with one or more closure members with a bottom panel having a contoured shape corresponding
to the contoured shape of the flexible or soft sided body, and a releasable attachment
member may extend along an outer periphery of the contoured bottom panel. The releasable
attachment members of the detachable transport system and the luggage piece may be
configured to releasably join with one another.
[0047] In some implementations, when the luggage piece is releasably joined with the detachable
transport system, the retractable handle may be arranged at a top side of the luggage
piece. The one or more wheels may be arranged at a bottom side of the luggage piece.
A portion of the soft sided body may be arranged along a length of a back side of
the luggage piece and may include a narrower middle region relative to the upper and
lower regions. The back side may be arranged between the top side and the bottom side.
[0048] In some implementations, the retractable handle may further include a pivot joint
assembly. The pivot joint assembly may be configured to pivot to enable the detachable
transport system to fold at a middle region of the flexible or soft sided body between
the upper and lower regions.
[0049] In some implementations, the luggage piece may be joined to the detachable transport
system. The luggage piece may be configured to fold at the back panel as the pivot
joint assembly pivots.
[0050] In some implementations, the pivot joint assembly may further include a telescoping
member joined to the handle. As the pivot joint assembly pivots, the telescoping member
may be configured to telescope into the pivot joint assembly and to retract the handle.
[0051] In another implementation, a luggage item or case may include a luggage body having
a contoured shape and having a top elongated face, a bottom elongated face, opposing
side faces, and first and second opposing end faces, the faces together defining an
internal compartment and at least one of the elongated faces is relatively rigid and
wherein the balance of the body is relatively flexible. A zipper closure mechanism
may be defined in the top elongated face for selectively exposing the internal compartment
of the body. A retractable handle may be provided at an upper region of the luggage
and extendable and retractable along the bottom elongated face. One or more wheels
may be mounted at least partially on the second opposing end face. A support member
may be mounted on the second opposing end face, the support member being extendable
along the face upon which it is mounted to support the body when standing on the second
opposing end face.
[0052] Additionally, the support member may include two bosses mounted on the second face,
each boss defining a recess. The support member may also define an extension bar having
a support portion and at least two leg portions, each of the leg portions being selectively
receivable in a corresponding recess. The extension bar may be movable between an
extended position and a retracted position, wherein in the extended position at least
a portion of the support bar extends beyond the interface of the top elongated face
and the second opposing end face.
[0053] Further, the zipper closure mechanism may include two or more zipper closure mechanisms
forming a general X-shape on the elongated top face. Even further, the luggage item
or case may be modified so that the zipper closure mechanism may include four segments,
each segment extending from a separate portion of the elongated top face and gathering
in generally the middle portion of the elongated top face to allow access to the internal
compartment when unzipped, and may form an X-shape.
[0054] The luggage items according to the various implementations may provide a user with
a selectively sized and shaped opening for packing or unpacking items and may provide
a proper securement among the various portions of materials forming such selectively
sized and shaped opening. The transport systems or devices according to the various
implementations is easy to use and flexible, yet still provide a secured attachment
between the transport device and a luggage item and/or a clean and aesthetically appealing
appearance when joined to the luggage item.
[0055] This summary is given to aid in understanding the luggage transport or the luggage
item, and one of ordinary skill in the art will understand that each of the various
aspects and features of the luggage transport or the luggage item may advantageously
be used separately in some instances, or in combination with other aspects and features
of these devices in other instances.

DETAILED DESCRIPTION
[0072] Described herein are detachable transport devices and systems for duffel bags, soft-sided
bags, hard-sided bags, or other types of luggage pieces. In some implementations,
the detachable transport device and system may be configured with a relatively flexible
body, wheels and a retractable handle, and the detachable transport system may detachably
join to a luggage piece for rolling transport of the luggage piece. The flexible body
of the transport system may include a soft-sided outer layer or cover which may be
formed using many relatively soft or non-rigid, flexible materials, such as natural
or man-made woven or non-woven fabrics, polymer sheets, or natural materials, such
as leather, and so on. In some implementations, the flexible body may additionally
but optionally include non-soft, relatively rigid yet still relative flexible sheets
or panels positioned inside the outer layer or cover as structural and shape reinforcements.
In some implementations, the flexible body may include a more rigid or harder member
as an anchor plate for attaching components, such as wheels. The detachable transport
system may include a telescoping handle for a user to grasp when towing the luggage
piece. In some implementations, the detachable transport system may be collapsed for
transport and storage. In some implementations, the detachable transport system and
the luggage piece may be provided together in a luggage transport system. In some
implementations, the luggage piece may be coupled to the transport system in a manner
such that the luggage piece may not be detachable from the rest of the transport system.
[0073] The detachable transport systems may have any size and shape. The flexible body of
the detachable transport system may include a longitudinal dimension and may include
along its longitudinal dimension an upper end portion, a lower end portion and a central
portion positioned between the upper end portion and the lower end portion. The central
portion may be formed with a width dimension different from at least one of the width
dimensions of the upper end portion or the lower end portion. Accordingly, the flexible
body of the detachable transport system may define a varying width across its length.
In some implementations, the flexible body of the detachable transport system may
define a contoured or curvilinear shape. Specifically, the upper end portion of the
flexible body may include a contoured or curvilinear upper region, the lower end portion
of the flexible body may include a contoured or curvilinear lower region, and the
central portion of the flexible body may include a relatively narrower middle region.
In some examples, the contoured or curvilinear shape may be similar to an hourglass
shape in which the upper and the lower regions may each be configured with a bulb-like
shape and the middle region may be configured as an extension of the narrow portions
of the bulb-like shape of the upper and lower regions. In some examples, the central
portion or the middle region itself may define an hourglass shape as the peripheries
of the central portion or the middle region may taper outwardly as they extend toward
the upper and lower regions.
[0074] Turning to the luggage transport system 100 depicted in Figs. 1A and 1B, the detachable
transport system 102 is shown detached from the luggage piece 104. The detachable
transport system 102 may include a flexible body 106 with a front panel 108 joined
to a back panel 110. The flexible body 106, as well as each of the front and back
panels 108, 110, may include a contoured or hourglass shape with an upper region 112,
a lower region 114 and a middle region 116 extending along a longitudinal dimension
of the flexible body 106. The middle region 116 may be configured with a relatively
narrower width or transverse dimension compared to the upper and lower regions 112,
114. The upper region 112 may extend away from the middle region 116 at an angle measured
between a front surface of the middle region 116 (i.e., the portion of the front panel
108 at the middle region 116) and a front surface of the upper region 112 (i.e., the
portion of the front panel 108 at the upper region 112). Similarly, the lower region
114 may extend away from the middle region 116 at an angle measured between the front
surface of the middle region 116 and a front surface of the lower region 114 (i.e.,
the portion of the front panel 108 at the lower region 114). Depending on the shape
of the luggage item 104 the detachable transport system 102 is joined to, the angle
between the upper region 112 and the middle region 116 and the angle between the lower
region 114 and the middle region 116 may vary. Since the body 106 is relatively flexible,
the upper region 112 and/or the lower region 114 may extend away from the middle region
116 at any angle from approximately 40 to approximately 140 degrees to conform to
the shape of the luggage piece 104 to which the detachable transport system 102 is
joined. The upper region 112 and/or the lower region 114 may fold toward the middle
region 116, thus extending away from the middle region 116 at an angle smaller than
40 degrees for storage as described below.
[0075] The upper region 112 may define a top edge 118 that transitions to the side edges
120 by a rounded contour. The side edges 120 may extend from the upper region 112
to the middle region 116 by tapering inwardly. Transitioning from the middle region
116 to the lower region 114, the side edges 120 may expand to a width that may be
approximately the same as the width of the upper region 112 and may transition to
the bottom edge 122 by a rounded contour. In some implementations, the tapering and
expanding of the side edges 120 and the rounded contour transitioning the side edges
120 to the top and bottom edges 118,122 may generally define an hourglass shape for
the detachable transport system 102.
[0076] The front panel 108 of the flexible or soft sided body 106 may include a closure
member 124 to access to an interior of the soft sided compartment described below
in connection with Fig. 4. The back panel 110 at the upper region 112 of flexible
or soft sided body 106 may be configured to be joined with a handle 126 and a handle
housing 128 (see Fig. 1B), and the lower region 114 of the flexible or soft sided
body 106 may be configured to be joined with one or more wheels 130, wheel housings
132 and stabilizing flanges 134.
[0077] A releasable attachment member 136 (e.g., one side of a zipper assembly) may be provided
on a peripheral edge of the flexible or soft sided body 106 and may be configured
to releasably join to a complementary releasable attachment member 138 (e.g., a second
side of a zipper assembly) provided on the luggage piece 104. In some examples, the
releasable attachment member 136 may be provided along a substantial portion (i.e.,
at least 50%) of the periphery of the flexible or soft sided body 106. In some embodiments,
the releasable attachment member 136 may be provided along at least 50%, preferably
75% or more of the periphery, more preferably 90% or more, or even more preferably
along the entire periphery of the body 106, for better securement of the luggage item
104 to the detachable transport system 102. In some embodiments, the releasable attachment
member 136 may be one single continuous member provided to the periphery of the flexible
or soft sided body 106 for easy attachment. In some examples, the releasable attachment
member 136 may include two or more releasable attachment elements provided along segments
of the periphery of the flexible or soft sided body 106.
[0078] The releasable attachment members 136, 138 may be joined and detached from one another
by a releasable attachment member pull 212 (e.g., a zipper pull of a zipper assembly
in Fig. 2B), which may be provided on one or both of the flexible or soft sided body
106 or the luggage piece 104.
[0079] The luggage piece 104 may be configured as a soft sided bag and may include a bottom
panel 140 with a contoured shape (e.g., an hourglass shape) similar to the contoured
shape of the flexible or soft sided body 106 of the detachable transport system 102.
The bottom panel 140 may extend along a portion of the top side 142, back side 144
and bottom side 146 of the luggage piece 104. At the top side 142 of the luggage piece
104, the bottom panel 140 may extend across a portion of the length of the top side
142 and may join along its edges to the upper panel 148 and the first and second side
panels 150, 152. At the bottom side 146 of the luggage piece 104, the bottom panel
140 may extend across a portion of the length of the bottom side 146 and may join
along its edges to the lower panel 154 and the first and second side panels 150, 152.
At the back side 144 of the luggage piece 104, the bottom panel 140 may extend along
the length of the back side 144 and may join to the first side panel 150 at the left
of the back side 144 and to the second side panel 152 at the right of the back side
144.
[0080] A releasable attachment member 138 may be provided around the periphery of the bottom
panel 140 and may be configured to releasably join to the releasable attachment member
136 of the detachable transport system 102. For example, one side 138 of a zipper
assembly on the luggage piece 104 may include a complementary configuration to another
side 136 of a zipper assembly provided on the detachable transport system 102, and
the two sides 136, 138 of the zipper assembly may be joined by a zipper pull 212 disposed
on one or the other of the luggage piece 104 and the detachable transport system 102.
The zipper pull 212 may be pulled in one direction to draw the two sides 136, 138
of the zipper assembly together to join the luggage piece 104 and the detachable transport
system 102 together. Once the luggage piece 104 and detachable transport system 102
are joined, the two may be detached from one another by pulling the zipper pull 212
in an opposite direction along the periphery of the detachable transport system 102
and the bottom panel 140.
[0081] Similar to the releasable attachment member 136 of the detachable transport system
102, the releasable attachment member 138 of the luggage piece 104 may be one single
continuous member or two or more releasable attachment elements provided to the periphery
of the bottom panel 140 of the luggage piece 104. The releasable attachment member
138 of the luggage piece 104 may be provided along a substantial portion (i.e., at
least 50%) of the periphery of the bottom panel 140. In some embodiments, the releasable
attachment member 138 may be provided along at least 50%, or preferably 75% or more,
more preferably 90% or more, or even more preferably along the entire periphery of
the bottom panel 140, for better securement of the luggage item 104 to the detachable
transport system 102.
[0082] Providing the releasable attachment members 136, 138 along substantial portions of
the respective peripheries of the flexible body 106 of the detachable transport system
102 and the bottom panel 140 of the luggage piece 104 securely attaches the luggage
piece 104 to the detachable transport system 102 and restricts movement of one relative
to the other. Further, such attachment or securement between the two reduces the likelihood
that the luggage piece 104 will be undesirably separated from the detachable transport
system 102. A user thus can transport the luggage item 104 using the detachable transport
system 102 with greater confidence that the luggage piece 104 will remain attached
to the detachable transport system 102. In addition, when each of the attachment members
136, 138 is configured as one continuous member, attaching and detaching the luggage
piece 104 to and from the detachable transport system 102 requires a single zipping/unzipping
operation rather than multiple operations when more than one zipper is utilized to
join the luggage piece 104 to the detachable transport system 102. A single zipper
may also create a relatively clean finished appearance to the combination of the luggage
piece 104 and the detachable transport system 102.
[0083] Because the bottom panel 140 extends along a portion of the top and bottom sides
142, 146 of the luggage piece 104 and the detachable transport system 102 may be joined
to the bottom panel 140, the detachable transport system 102 may form a c-shaped cradle
surrounding portions of the top, back and bottom sides 142, 144, 146 of the luggage
piece 104. Accordingly, the upper region 112 of the detachable transport system 102
may cover or overlap a portion of the top side 142 of the luggage piece 104, and the
lower region 114 of the detachable transport system 102 may cover or overlap a portion
of the bottom side 146 of the luggage piece 104. In some examples, the upper region
112 may be configured to cover or overlap no less than 20%, preferably no less than
50%, more preferably no less than 80% of a surface area of the top side 142 of the
luggage item 104. Similarly, in some examples, the lower region 114 may be configured
to cover or overlap no less than 20%, preferably no less than 50%, more preferably
no less than 80% of a surface area of the bottom side 146 of the luggage item 104.
In some examples, the upper region 112 and the lower region 114 of the detachable
transport system 102 may be configured to be coextensive with a depth dimension of
the top side 142 and the bottom side 146, respectively, or coextensive with a depth
dimension of the luggage piece 104 measured from a front side 190 to the back side
144 of the luggage piece 104.
[0084] Such surrounding, overlapping or coextensive configuration between the detachable
transport system 102 and the top, back and bottom sides 142, 144, 146 of the luggage
piece 104 provides added securement of the luggage item 104 to the detachable transport
system 102. Especially during transportation, the top and bottom sides 142, 146 of
the luggage piece 104 may come into contact with objects that exert a force to the
luggage piece 104 in a direction opposite to the direction of travel, the overlapping
or coextensive configuration between the upper and lower regions 112, 114 of the detachable
transport system 102 and the top and bottom sides 142, 144 of the luggage piece 104
may help prevent accidental detachment of the two caused by such force.
[0085] The handle 126 at the top of the detachable transport system 102 may be used to tow
the luggage piece 104 from the top side 142, and the wheels 130 at the bottom of the
detachable transport system 102 may be used to roll the luggage piece 104 during towing.
The portion of the detachable transport system 102 extending along the length of the
bottom side 146 of the luggage piece 104 may provide some support to the bottom side
146 of the luggage piece 104, which may limit sagging of the luggage piece 104 at
its bottom side 146 during rolling transport.
[0086] In some embodiments, the luggage piece 104 may include one or more materials that
define an internal compartment thereof. The one or more materials may be configured
to form a first portion 148, for example, an upper panel 148, a second portion 154,
for example, a lower panel 154, a third portion 150, for example, a first side panel
150, and a fourth portion 152, for example, a second side panel 152. While the upper
panel 148 is referred to as the first portion, the lower panel is referred to as the
second portion, and so on, this is merely for convenience to aid the reader's understanding
of the luggage piece 104. Thus, any one of the upper, lower, first side or second
side panels 148, 150, 152, 154 may be referred to as the first portion, any of the
other three panels may be referred to as the second portion, and so on.
[0087] Each of the first, second, third and fourth portions 148, 150, 152, 154 may include
a wider end adjacent to a corresponding portion of the periphery of the bottom panel
140, a tapered end terminating at a center of the front side 190 of the luggage piece
104 when the luggage piece 104 is in a closed configuration (see Figs. 1A, 1B and
2A), and two sides that join the wider end to the tapered end and that may be curved
or otherwise suitably shaped. In some embodiments, the two sides may converge at the
tapered end thus forming in general a triangular shaped portion of the luggage piece
104. In some embodiments, the wider end, the tapered end, and the two sides may collectively
define in general a trapezoid shaped portion of the luggage piece 104. In some embodiments,
the wider end, the tapered end and the two sides in between may take the form of four
portions of a continuous smooth circumference of the first, second, third or fourth
portion 148, 150, 152, 154 of the luggage item 104, thus defining a shape with rounded
corners or no corners.
[0088] In some implementations, the luggage piece 104 may include a cross-shaped or X-shaped
closure system 160 with four closure members 162, 164, 166, 168 extending diagonally
from the four corners of the luggage piece 104 to the center of the luggage piece
104. The cross-shaped or X-shaped closure system 160 may be joined to the two sides
of each portion 148, 150, 152, 154 and may be configured to selectively couple and
uncouple the first portion or the upper panel 148 and the second portion or the lower
panel 154 to the third and fourth portions or the first and second side panels 150,
152 of the luggage piece 104 to selectively close and open the luggage piece 104.
For example, the upper panel 148 of the luggage piece 104 may carry along each of
its two sides a portion of the first closure member 162 and a portion of the second
closure member 164. The first side panel 150 of the luggage piece 104 may carry along
each of its two sides a portion of the second closure member 164 and a portion of
the third closure member 166. The lower panel 154 of the luggage piece 104 may carry
along each of its two sides a portion of the third closure member 166 and a portion
of the fourth closure member 168. The second side panel 152 of the luggage piece 104
may carry along each of its two sides a portion of the fourth closure member 168 and
a portion of the first closure member 162. In this example, as the portions of the
first closure member 162 are closed, the side of the upper panel 148 and the side
of the second side panel 152 carrying the first closure portions may be joined up
to the center of the front side 190 of the luggage piece 104. As the portions of the
second closure member 164 are closed, the side of the upper panel 148 and the side
of the first side panel 150 carrying the second closure portions may be joined up
to the center of the front side 190 of the luggage piece 104. As the portions of the
third closure member 166 are closed, the side of the lower panel 154 and the side
of the first side panel 150 carrying the third closure portions may be joined up to
the center of the front side 190 of the luggage piece 104. As the portions of the
fourth closure member 168 are closed, the side of the lower panel 154 and the side
of the second side panel 152 carrying the fourth closure portions may be joined up
to the center of the front side 190 of the luggage piece 104. As may be appreciated,
upon closing the four closure members 162, 164, 166, 168, the luggage piece 104 may
be in the closed configuration shown in Figs. 1A and 1B with the tapered ends of the
first, second, third and fourth portions 148, 150, 152, 154 of the luggage piece 104
terminating proximate to the center of the X-shape.
[0089] By selective opening of one or more of the closure members 162, 164, 166, 168 and
by selective movement of one or more of the four portions 148, 150, 152, 154 relative
to the other portions, an opening may be formed for accessing the internal compartment
of the luggage piece 104. In some embodiments, an X-shaped opening may be defined
by selective movement of the upper panel 148 and the lower panel 154 relative to the
first side panel 150 and the second side panel 152 of the luggage piece 104. The X-shaped
opening may also be defined by selective movement of the first side panel 150 and
the second side panel 152 relative to the upper panel 148 and the lower panel 154
of the luggage piece 104. Specifically, by selectively opening the closure members
162, 164, 166, 168, the tapered ends of the upper and lower panels 148, 154 may be
selectively moved away from the center of the X-shape forming an X-shaped opening,
while the tapered ends of the first and second side panels 150, 152 may remain at
the center of the X-shape, and may be optionally attached to each other by an additional
securing mechanism as described below. Alternatively, the tapered ends of the upper
and lower panels 148, 154 may remain at the center of the X-shape and may be optionally
attached to each other by an additional securing mechanism as described below. The
tapered ends of the first and second side panels 150, 152 may be selectively moved
away from the center of the X-shape, thus defining an X-shaped opening.
[0090] Other shapes of the opening may be formed by selective opening of the closure members
162, 164, 166, 168 and by selective movement of one or more of the four portions 148,
150, 152, 154 relative to the other portions. In some embodiments, a triangular shaped
opening may be formed by selective movement of only one of the four portions 148,
150, 152, 154 relative to the other three. In this instance, only two closure members
that are coupled to that portion of the luggage piece 104 may be opened while other
closure members may remain closed. In some embodiments, a larger triangular shaped
opening may be formed by selective movement of two adjacent portions of the four portions
148, 150, 152, 154 relative to the other two. In this instance, three closure members
that are coupled to these two opened portions may be opened while the fourth closure
member may remain closed.
[0091] An X-shaped opening or an opening of other shapes may be desirable when a user only
needs a small opening to retrieve select items from the luggage piece 104, while a
fully opened configuration is still available when the user desires to pack or unpack
the luggage item 104.
[0092] The luggage piece 104 may include additional closure members such as snap closure
170 (see Fig. 8A) or hook and loop closures 172 (see Fig. 8B) for securing the panels
together in the closed configuration. For example, a portion of the upper and lower
panels 148, 154 in an area proximate to the center of the luggage piece 104 may include
closure members that may releasably join the upper and lower panels 148, 154. In addition
or alternatively, the first and second side panels 150, 152, in an area proximate
the center of the luggage piece 104 may include releasable closure members.
[0093] In some implementations, shoulder straps 174 shown in Figs. 1A and 1B may be provided
in a central area of the first and second side panels 150, 152. The shoulder straps
174 may be stowed in a first side pocket 176 and a second side pocket 178 that may
respectively be provided by the first and second side panels 150, 152.
[0094] Turning to Figs. 2A-2F, the detachable transport system 102 is shown joined to the
luggage piece 104. Fig. 2A shows a front side view of the detachable transport system
102 joined to the luggage piece 104 by the releasable attachment members 136, 138
provided on the detachable transport system 102 and the luggage piece 104. The closure
panel 180 may cover the closure pulls 182 (e.g., zipper pulls) when the luggage piece
104 is in the closed configuration of Fig. 2A.
[0095] Fig. 2B shows a back side view of the detachable transport system 102 joined to the
luggage piece 104. The releasable attachment members 136, 138 may follow the contoured
or hourglass shape of the soft sided compartment of the detachable transport system
102 and the contoured or hourglass shape of the bottom panel 140 of the luggage piece
104. In this implementation, a lower portion of each of the first side panel 150 and
second side panel 152 may form a back side 144 of the luggage piece 104 along with
a portion of the bottom panel 140, and the side panels 150, 152 may each be exposed
when the detachable transport system 102 is joined to the bottom panel 140 of the
luggage piece 104. The hourglass configuration of the detachable transport system
102 matching the hourglass shaped configuration of the bottom panel 140 may enable
the upper, lower, first side and second side panels 148, 150, 152, 154 of the luggage
piece 104 to take the shape of the contents within the luggage piece 104 without interference
from the components of the detachable transport system 102. In some implementations,
the handle 126 and any handle members (e.g., the retractable handle assembly 184 of
Fig. 4 or the telescopic foldable towing handle 186 of Figs. 5A-5F) or wheel support
structures provided by the detachable transport system 102 may give some support to
the back side 144 of the luggage piece 104 in an area corresponding to the bottom
panel 140 of the luggage piece 104. In Fig. 2B, the handle 126 is shown recessed in
the handle housing 128 of the detachable transport system 102. It may be appreciated
that the handle 126 may be extended from the handle housing 128 and may be used to
tow the luggage piece 104 joined to the detachable transport system 102 by rolling
transport via the wheels 130 of the detachable transport system 102.
[0096] Fig. 2C shows a bottom plan view of the detachable transport system 102 joined to
the luggage piece 104 and illustrates that the third and the fourth closure members
166, 168 of the luggage piece 104 may be accessible when the releasable attachment
members 136, 138 are joined to one another. That is, while the detachable transport
system 102 is joined to the luggage piece 104, the luggage piece 104 may be opened
and closed by the third and fourth closure members 166, 168. In Fig. 2C, the wheel
160 and wheel housing 132 may be arranged on the sides of the bottom surface 188 of
the detachable transport system 102 in an area proximate where the bottom surface
188 transitions to the back surface 192 of the detachable transport system 102. One
or more stabilizing flanges 134 may be arranged in an upper middle region of the bottom
surface 188 and may provide stability to the detachable transport system 102 and luggage
piece 104 when the system is balanced on the bottom surface 188.
[0097] Fig. 2D shows a top plan view of the detachable transport system 102 joined to the
luggage piece 104 by the releasable attachment members 136, 138 and illustrates that
the first and second closure members 162, 164 of the luggage piece 104 may be accessible
in the configuration shown. The handle 126 retracted in the handle housing 128 of
the detachable transport system 102 may be extended from the detachable transport
system 102 without interfering with the operation of the first and second closure
members 162, 164.
[0098] Fig. 2E shows a left side view of the detachable transport system 102 joined to the
luggage piece 104. The second side panel 152 extends along the front side 190, left
side 156 and back side 144 of the luggage piece 104. The right side 158 of the detachable
transport system 102 and luggage piece 104 joined thereto may appear substantially
similar to the left side view of Fig. 2E, and the first side panel 150 may extend
along the front side 190, right side 158, and back side 144 of the luggage piece 104.
The first and second side panels 150, 152 may join the bottom panel 140 of the luggage
piece 104 at the back side 144, and the intersection between the bottom panel 140
and the first and second side panels 150, 152 may be shaped with the bulbous contour
and middle region of a contoured or hourglass shaped bottom panel. Thus, in Fig. 2E
it may be appreciated that the releasable attachment member 138 of the luggage piece
104 may extend along the bottom panel 140 on the periphery of the top left side and
bottom left side of the luggage piece 104, and may transition to the back side 144
of the luggage piece 104 (see Fig. 2B). While not shown, the right side 158, similar
to the left side 156 shown in Fig. 2E, may include the releasable attachment member
138 of the luggage piece 104, which may extend along the bottom panel 140 on the periphery
of the top right side and bottom right side of the luggage piece 104, and may transition
to the back side 144 of the luggage piece 104 (see Fig. 2B).
[0099] Fig. 2F shows a perspective view of the detachable transport system 102 joined to
the luggage piece 104 when the luggage piece 104 is in an opened configuration. The
four panels 148, 150, 152, 154 carrying the four closure members 162, 164, 166, 168
may be positioned in the open configuration by drawing the closure pulls 182 to the
corners of the front side 190 of the luggage piece 104. Webbing or gussets 194 may
be provided between each adjacent panel and may enable the panels 148, 150, 152, 154
to be drawn open to a degree that may prevent stressing the closure members 162, 164,
166, 168 and closure pulls 182 at the corners of the luggage piece 104. In some implementations,
the luggage piece 104 may include one or more internal pockets 196 and luggage straps
198. As shown in Fig. 2F, the luggage piece 104 may be arranged in the opened configuration
when joined to the detachable transport system 102. From the opened configuration,
the luggage piece 104 may be placed in the closed configuration by drawing the four
closure pulls 182 to a central portion of the front side 190 of the luggage piece
104 described above in connection with Figs. 1A and 1B.
[0100] Turning to Figs. 3A-3D, the detachable transport system 102 may be configured as
a foldable system. Fig. 3A shows the detachable transport system 102 in an initial
position in which the wheels 130 and handle 126 are at opposite ends of the detachable
transport system 102. In this position, the wheels 130 and handle 126 of the detachable
transport system 102 may be used to transport a luggage piece 104 (see Fig. 1A) by
joining the releasable attachment member 136 of the detachable transport system 102
with a complementary releasable attachment member 138 (see Fig. 1A) provided on corresponding
portions of the luggage piece 104. With reference to Fig. 3B, the middle region 116
of the detachable transport system 102 may fold, such as by collapsing a support member
(not shown) arranged within an interior of the detachable transport system 102. As
the middle region 116 begins to fold, the upper region 112 and lower region 114 at
the front surface 200 of the detachable transport system 102 may begin to move towards
one another. The folding may continue as shown in Fig. 3C so that a top surface 142
of the detachable transport system 102 overlaps the bottom surface 188 and the wheels
130 and handle 126 are arranged adjacent to each other. A flexible strap 202 may join
or hold the upper region 112 and lower region 114 together in the folded configuration
of the detachable transport system 102 as shown in Fig. 3D. The foldable detachable
transport system 102 may be collapsed into a compact shape that may enable the detachable
transport system 102 to be individually transported, e.g., carried by the grip 222
or the handle 126 separate from the luggage piece 104, or may be stowed within the
luggage piece 104 of Figs. 1A and 1B.
[0101] In some implementations, the luggage piece 104 may be joined to the foldable detachable
transport system 102 when the foldable detachable transport system 102 is collapsed.
For example, this may enable the luggage piece 104 to be compacted along with the
foldable detachable transport system 102 when the two are not in use, such as after
the luggage piece 104 is unpacked or when the luggage piece 104 and the foldable detachable
transport system 102 are to be stored.
[0102] Turning to Fig. 4, components that may be provided in the detachable transport system
102 are shown in an exploded view. The detachable transport system 102 may include
a flexible or soft sided body 106 having a front panel 108 and a back panel 110 joined
along their outer periphery, and the front panel 108 may include a compartment closure
member 124 with a first side 204 and a second side 206 (such as a zipper assembly)
for providing access to a compartment interior 208 defined between the front and back
panels 108, 110. The compartment closure 124 (such as a zipper assembly) may be opened
and closed using a closure pull 210 (such as a zipper pull). In some implementations,
the front panel 108 and the back panel 110 may be formed of a flexible or pliable
material such as a fabric or a durable polymer sheet.
[0103] In some implementations, a portion of the retractable handle assembly 184, a body
base 214 and other components may be provided within the compartment interior 208
and may be accessible using the closure pull 210. In some implementations, the components
within the compartment interior 208 may provide the detachable transport system 102
with some rigidity. For example, one or more sheets may be provided within the compartment
and the sheets may have some pliability and strength for maintaining the shape of
the flexible or soft sided body 106 when detached from the luggage piece 104. The
detachable transport system 102 may be constructed of flexible materials that enable
the detachable transport system 102 to fold or collapse described in connection with
Figs. 3A-3D without breaking the flexible materials, while at the same time, the flexible
materials may have sufficient rigidity to allow the shape of the flexible or soft
sided body 106 to be maintained when separated from the luggage piece 104.
[0104] In some implementations, the back panel 110 at the upper region 112 may include an
opening sized to receive a handle housing 128 therethrough. The handle housing 128
may receive a telescopic member 216 of the retractable handle assembly 184, described
below. The lower region 114 of the back panel 110 may form wheel housing openings
for receiving the wheel housings 132, described below.
[0105] The detachable transport system 102 may include a retractable handle assembly 184
with a handle 126 joined to the telescopic member 216, a retractable handle assembly
receiving member 218 for receiving the telescopic member 216 at a first end, and a
retractable handle assembly base 220 for joining to the second end of the retractable
handle assembly receiving member 218 and to the base 214 of the flexible or soft sided
body 106. The detachable transport system 102 may be provided with some rigidity in
the portions where the retractable handle assembly 184 is received, for example, due
to the telescopic member 216, receiving member 218 and base 220 of the retractable
handle assembly 184 being formed of materials such as metal or a substantially inflexible
polymer. In some implementations, the retractable handle assembly 184 may be configured
as a collapsible handle assembly and may enable the detachable transport system 102
to fold in the manner shown and described in connection with Figs. 3A-3D.
[0106] The body base 214 may be constructed of a polymer sheet material that may provide
some rigidity to the lower region 114 of the flexible or soft sided body 106 and may
form openings for receiving a portion of the wheel housings 132. The wheel housings
132 may be arranged at the lower region 114 of the flexible or soft sided body 106
and may extend through openings formed in the back panel 110 and in the openings formed
in the base 214. In some implementations, the wheel housings 132 may include an axle
(not shown) and may support the wheels 130 and enable the wheels 130 to spin. The
stabilizing flanges 134 may be fixedly joined to the back panel 110 of the flexible
or soft sided body 106 such as through a boss and fastener assembly, welding, adhering,
sewing, and the like and may provide some stability to the luggage transport system
100 or the detachable transport system 102 when in an upright position, e.g., when
supported by the wheels 130 and stabilizing flanges 134 at the bottom surface 188
of the detachable transport system 102.
[0107] Turning to Figs. 5A-5G, illustrated are a telescopic foldable towing handle 186 and
components of the telescopic foldable towing handle 186 that may be utilized in combination
with the detachable transport systems 102 disclosed herein. For example, the telescopic
foldable towing handle 186 may be used with the detachable transport systems 102 for
transporting luggage instead of the retractable handle assembly 184 of Fig. 4, and
when not used for luggage transport, the telescopic foldable towing handle 186 may
be collapsed and the detachable transport system 102 may be folded into a compact
shape as shown in Figs. 3A-3D such as for individual transport and storage.
[0108] Fig. 5A shows a left side view of the telescopic foldable towing handle 186 with
a pivot joint 230, a first pivot member 232 and a second pivot member 234 joined to
the pivot joint 230, a telescopic member 236 received by the first pivot member 232,
a cable 238 arranged between and joined to the pivot joint 230 and the telescopic
member 236, and a handle 240 joined to the telescopic member 236. Fig. 5B illustrates
an exploded view of the telescopic foldable towing handle 186 showing separate pivot
joint components including the first pivot arm 242, second pivot arm 244, cable pivot
covering 246, a pivot fastener 248, and a cable 238.
[0109] With reference to Fig 5B, the handle 240 of the telescopic foldable towing handle
186 may join to a first end 250 of the telescopic member 236 by a boss and fastener
assembly (not shown). It may be appreciated that the boss and fastener assemblies
provided herein may include various types of mechanical fasteners (e.g., threaded
screws, stitches, rivets, snaps and so on), adhesives, welds or any other known connection
mechanism. A second end 252 of the telescopic member 236 may be received by a first
end 254 of the first pivot member 232 and telescopic member 236 may extend into the
interior of the first pivot member 232. A cable 238 may join to an interior of the
telescopic member 236, described below. The telescopic member 236 may be configured
as a generally elongated hollow tubular structure and may include a circular, rectangular,
oval, or other shaped cross section.
[0110] The first pivot member 232 may receive the telescopic member 236 at the first end
254 of the first pivot member 232 and may join to a first pivot arm 242 of the pivot
joint assembly 230 at a second end 256 of the first pivot member 232. The first pivot
member 232 may be joined to the first pivot arm 242 by a first pivot arm boss 258
(see Fig. 5C) and a first pivot arm fastener assembly (not shown). The first pivot
member 232 may be configured as a generally elongated hollow tubular structure and
may include a circular or oval-shaped cross section with an internal circumference
that is slightly larger than an external circumference of the telescopic member 236.
[0111] The cable 238 may be arranged between the telescopic member 236 and the pivot joint
assembly 230. In the assembled state of the telescopic foldable towing handle 186,
the first end 260 of the cable 238 may extend through the second end 256 of the first
pivot member 232 into the interior of the first pivot member 232 and through the second
end 252 of the telescopic member 236 into the interior of the telescopic member 236.
The first end 260 of the cable 238 may join to the interior of the telescopic member
236 by a cable boss 262 and cable fastener 264 assembly. The second end 266 of the
cable 238 may extend through the first pivot arm 242 of the first pivot housing 268
and may join to the pivot joint 230 in an area corresponding to an interior of the
cable pivot covering 246 and the second pivot housing 270 (see Fig. 5D). The cable
238 may be configured to bend and articulate within the pivot joint assembly 230,
described below, and may be constructed of a thermoplastic polymer such as polyoxymethylene
(POM) (e.g., DuPont Delrin). While Figs. 5A-5D and 5G illustrate the cable 238 with
a cable boss configuration 262, 272 at each end, the cable 238 may be configured with
cable fasteners 264, 274 at one or both of the first end 260 and the second end 266.
[0112] The pivot joint assembly 230 may include three housing portions: a first pivot housing
268, a second pivot housing 270 and a cable pivot covering 246. The pivot housings
268, 270 may be configured with a circular body and a pivot arm 242, 244 extending
from a lower portion of the circular body. In the assembled and locked position of
the pivot joint assembly 230 in Fig. 5A, the first and the second pivot arms 242,
244 of the pivot joint assembly 230 may be coaxial. The circular body of the pivot
housings 268, 270 may be configured to rotationally join to one another along facing
sidewalls to enable relative rotation of the circular bodies.
[0113] The first pivot housing 268 may be configured with a body having a circular, rounded
outer wall, an actuator recess 276 formed at an exterior of the first pivot housing
268 for receiving an actuator 278, an actuator opening 280 formed in the actuator
recess 276 and extending into the interior of the first pivot housing 268 for receiving
actuator legs of the actuator 278, a wall within an interior of the first pivot housing
268 for receiving the actuator gear 282, and in some cases, the keyed portions 298
of the actuator gear 282 in the locked position of the pivot joint assembly 230 (e.g.,
an actuator gear recess 292 with one or more keyed recesses 294, 296), and a tab-receiving
recess formed in the interior of the first pivot housing 268 for receiving the cable
pivot covering tabs 284. The first pivot arm 242 may extend from the body of the first
pivot housing 268 and may be configured to be joined to the first pivot member 232,
such as through a boss and fastener connection.
[0114] The second pivot housing 270 may include a circular, planar outer wall with a second
pivot housing extension 286 extending from the outer wall for abutting with the first
pivot arm 242 in the assembled and locked position of Fig. 5A. The second pivot arm
244 may extend from an opposite side of the planar outer wall from where the pivot
housing extension 286 is located and may be configured to be joined with the second
pivot member 264 such as through a boss and fastener connection. A first side 288
of the second pivot housing 270 may be configured to receive the cable pivot covering
246 and may include circular sidewalls for receiving the cable pivot covering 246.
A second side 290 of the second pivot housing 270 may include an actuator gear recess
292 with first and second keyed recess 294, 296 for receiving the actuator gear 282
and the keyed extensions 298 of the actuator gear 282 in the locked and unlocked position
of the pivot joint assembly 230. A second pivot arm boss 302 may extend between the
sides of the second pivot housing 270 at a central region and may be configured with
a shape for receiving the cable pivot covering axle 304, e.g., a cylindrical shape.
The outer wall forming the second pivot arm boss 302 may be configured with a cylindrical
shape for receiving the actuator gear 282 at the actuator gear opening 300.
[0115] The cable pivot covering 246 may be configured as a covering for the first side 288
of the second pivot housing 270 and the cable 238 of the pivot joint assembly 230.
The cable pivot covering 246 may include an outer wall with a similar shape to the
shape of the first side 288 of the second pivot housing 270, such as a circular shaped
outer wall. The cable pivot covering 246 may include an internal wall configured to
rotatably join to the first side 288 of the second pivot housing 270, such as through
circular a tongue and groove arrangement that enables the cable pivot covering 246
to join to and rotate relative to the second pivot housing 270. A cable pivot covering
axle 304 may extend from an interior of the cable pivot covering 246 and may form
a cable pivot covering boss 306 for receiving the pivot fastener 248. Cable pivot
covering tabs 284 may be formed at the terminal end of the cable pivot covering axle
304, and the cable pivot covering axle 304 may be received by and extend through the
second pivot housing 270 and may join to the first pivot housing 268 by the cable
pivot covering tabs 284 engaging with to the tab-receiving recesses formed in the
first pivot housing 268 for enabling the cable pivot covering boss 306 and the first
pivot housing 268 to simultaneously rotate (e.g., rotate in unison) during operation
of the pivot joint assembly 230. The cable pivot covering boss may receive a pivot
fastener, described below.
[0116] The pivot fastener 248 may join the housing portions 246, 268, 270 of the pivot joint
assembly 230. For example, the pivot fastener 248 may include an enlarged distal end
308 that may abut an external wall of the cable pivot covering 246, and the body 310
of the pivot fastener 248 may extend through the cable pivot covering axle 304 via
the cable pivot covering boss 306, through a second pivot housing boss 302 and through
a first pivot housing pivot boss. A proximal end of the boss 306 may join to the first
pivot housing 268 by a boss and fastener used to join the proximal end of the boss
306 to an internal wall of the first pivot housing 268, such as an internal wall forming
the bottom portion of the actuator recess 276. A washer 312 may be positioned between
the proximal end of the pivot fastener 248 and internal wall of the first pivot housing
268 and the fastener 248 may extend through the washer 312 and may facilitate securing
the proximal end of the pivot fastener 248 to the internal wall of the first pivot
housing 268.
[0117] The second pivot member 234 may be configured as a generally elongated hollow tubular
structure and may include a circular or oval-shaped cross section with an external
circumference that is slightly smaller than an internal circumference of the second
pivot arm 244. A second end of the second pivot member 234 may join to a base of the
detachable transport system 102 (see Fig. 4).
[0118] Fig. 5C illustrates another exploded view of the pivot joint assembly 230 of the
telescopic foldable towing handle 186. The pivot joint assembly 230 may include an
actuator 278 such as a push button for enabling the pivot housings 268, 270 of the
pivot joint assembly 230 to pivot relative to one another. The actuator 278 may include
actuator arms 314 extending towards the actuator recess 276 of the first pivot housing
268, and actuator arm flanges 316 may be formed at the terminal ends of the actuator
arms 314. The actuator arms 314 may enable the externally arranged actuator 278 to
operatively couple with the actuator gear 282 arranged within the pivot joint assembly
230. The actuator arm flanges 316 may serve as hooks or fasteners to enable the actuator
legs to remain in an interior of the pivot joint assembly 230 when the actuator 278
is urged outwardly by the biasing member 318 in the assembled state. The actuator
278 positioned within the actuator recess 276 of the first pivot housing 268 may operatively
couple to the biasing member 318 by way of the actuator arms 314, actuator arm flanges
316 and the second wall 322 of the actuator gear 282.
[0119] The actuator gear 282 may be positioned between the pivot housings 268, 270 for selectively
preventing and allowing the pivot housings 268, 270 to rotate relative to one another.
The actuator gear 282 may be configured with keyed extensions 298 along the outer
periphery and an actuator gear opening 300 may be formed as a cylindrical opening
in the central portion of the actuator gear 282. A first wall 320 of the actuator
gear 282 may contact the biasing member 318 and the second wall 322 of the actuator
gear 282 may contact the actuator arms 314 and actuator arm flanges 316 of the actuator
278 as well as the wall within the interior of the first pivot housing 268. The actuator
gear 282 may operatively couple to one or both of the first or second pivot housing
268, 270 for locking and unlocking the pivot joint assembly 230, described below.
Although two key portions 298 are shown on the actuator gear 282, only one key portion
298 may be needed to selectively prevent and allow rotation of the pivot housings
268, 270.
[0120] In the assembled state of the pivot joint assembly 230, the biasing member 318, which
may be a coil spring or the like, may be arranged within a second actuator gear recess
292 of the second pivot housing 270 between a wall of the actuator gear recess 292
and a first wall 320 of the actuator gear 282. The biasing member 318 may be configured
with an internal diameter that enables the outer wall of the second pivot arm boss
302 to extend through the biasing member 318. The second wall 322 of the actuator
gear 282 may contact actuator arms 314 formed on the actuator 278 that may extend
through the actuator opening 280 defined through a wall of the actuator recess 276.
The actuator arms 314 may provide the actuator 278 with access to an interior of the
assembled pivot joint assembly 230 so that the actuator 278 is biased outwardly by
the biasing member 318.
[0121] In operation of the pivot joint assembly 230 of the telescopic foldable towing handle
186, the components of the telescopic foldable towing handle 186 may be in an initial
state as shown in Figs. 5A and 5E, in which the telescopic members 236 may be extended.
The initial state may correspond to the cable 238 being arranged in a non-rotated
or relaxed position as shown in Fig. 5D. In this position, the telescopic member 236
and handle 240 may extend from the detachable transport system 102 by a distance that
enables the handle 240 to be utilized to tow a luggage piece joined thereto. In addition,
in the initial state, the biasing member 318 may be in an extended, semi-compressed
state for urging the actuator 278 to the initial position shown in Figs. 5A and 5E.
This position may correspond to the keyed portions 298 of the actuator gear 282 being
concurrently positioned within the keyed recesses 294, 296 formed in the second pivot
housing 270 and against one or more walls formed in the first pivot housing 268. In
this position, the outer wall 326 of the actuator gear 282 may abut portions of the
interior of the first and second pivot housings 268, 270 to cause the pivot housings
268, 270 to be locked.
[0122] From the initial state in which the keyed extensions 298 on the actuator gear 282
may be concurrently received within the corresponding portions of the first and second
pivot housings 268, 270 (e.g., the wall of the first pivot housing 268 and the keyed
recesses 294, 296 of the second pivot housing 270), which prevent the pivot housings
268, 270 from being rotated relative to each other, to allow rotation, the actuator
gear 282 is moved towards the cable pivot covering 246, which moves the keyed extension
298 of the actuator gear 282 out of abutment with a wall of the first pivot housing
268 and towards or further into the keyed recesses 294, 296 defined by the second
pivot housing 270. This then allows the first pivot housing 268 to be rotated relative
to the second pivot housing 270.
[0123] Thus, from the initial state, the actuator 278 may be actuated such as by pressing
the actuator 278 towards the cable pivot covering 246. The actuator 278 may slave
the actuator arms 314 in movement so that the actuator arms 314 press the actuator
gear 282 against the force of the biasing member 318 away from the first pivot housing
268 and into the second actuator gear recess 292 and the keyed recesses 294, 296 of
the second pivot housing 270. While the actuator gear 282 is arranged within the second
pivot housing 270, the pivot housings 268, 270 may be rotated relative to one another.
For example, a force exerted against one of the pivot members 232, 234 may cause the
first and second pivot housing 268, 270 of the pivot joint assembly 230 to pivot relative
to one another as illustrated in Fig. 5F. However, as shown in Figs. 5A and 5C, the
second pivot housing extension 286 may prevent rotation of the pivot housings 268,
270 in one direction. For example, the first pivot housing 268 may be prevented from
rotating in the counterclockwise direction by abutting with the second pivot housing
extension 286.
[0124] Returning to Fig. 5F, as the pivot housings 268, 270 move relative to one another,
the actuator gear 282 may be arranged within the actuator recess 276. This position
of the actuator gear 282 may correspond to an unlocked position of the pivot joint
assembly 230. In this position, the actuator gear 282 and biasing member 318 may be
blocked from moving into the interior chamber. During relative rotation, the first
pivot housing 268 slaves the pivot cable covering 246, for example due to the engagement
between the cable pivot covering tabs 284 and the tab-receiving recesses of the first
pivot housing 268, due to the engagement between the pivot fastener 248 and the first
pivot housing 268 or both.
[0125] As the pivot housings 268, 270 rotate or pivot relative to one another in the unlocked
position of the pivot joint assembly 230, the cable 238 joined between the telescopic
member 236 and the pivot joint assembly 230 may be wrapped around a pivot barrel 324
within the interior chamber defined between the cable pivot covering 246 and the second
pivot housing 270. The cable 238 may be configured with a substantially fixed length,
and as a result of the wrapping action of the cable 238 around the pivot barrel 324,
the cable 238 may pull the telescopic member 236 joined thereto into the first pivot
member 232. Due to the pivot operation of the pivot joint assembly 230 and the retracting
operation of the cable 238 and telescopic member 236, the handle 240 may be received
within a handle housing 128 of the detachable transport system 102 during the rotation
of the first pivot housing 268 relative to the second pivot housing 270 from the position
shown in Fig. 5A to the position shown in Fig. 5G. For example, the telescopic member
236 and the handle 140 may be positioned in the fully retracted position of Fig. 5G
when the telescopic foldable towing handle 186 is arranged within the detachable transport
system 102 shown in Fig. 3D.
[0126] According to some implementations, the pivot joint assembly 230 may be rotated or
pivoted from the pivoted state, e.g., the positions shown in Figs. 5F and 5G, back
to the initial state, e.g., the position shown in Figs. 5A and 5E. In this operation,
rotating the pivot housing portions 268, 270 to the position of Fig. 5A may cause
the actuator gear 282 arranged within the second actuator gear recess 292 to be pressed
by the biasing member 318 into the interior chamber of the pivot housing 268 so that
the actuator gear 282 is concurrently received in the first and second actuator gear
recesses 276, 292, which may correspond to the locked position of the actuator gear
282. In some implementations, moving the pivot joint assembly 230 from the pivoted
state to the initial state may cause the cable 238 to urge the telescopic member 236
to the extended position of the telescopic member 236 shown in Figs. 5A and 5E. Alternatively,
moving the pivot joint assembly 230 to the initial state may relax the cable 238,
and the telescopic member 236 may be manually pulled or extracted from the interior
of the first pivot member 232, such as by pulling the handle 240 away from the first
pivot member 232 until the cable 238 reaches the position shown in Fig. 5D.
[0127] Within the detachable transport system 102, the pivot joint assembly 230 may be arranged
in an area corresponding to a middle region 116 of the soft sided enclosure 224 of
the detachable transport system 102, and the first and second pivot members 232, 234
may be arranged respectively in upper and lower regions 112, 114 of the soft sided
enclosure 224. The pivot joint assembly 230 may be activated by pressing the actuator
278, either by accessing the compartment interior 208 of the soft sided enclosure
224 using the closure pull 210 and pressing the actuator 278 or by pressing the material
forming the front or back panel 108, 110 and the underlying actuator 278. That is,
because the soft sided enclosure 224 may be constructed of pliable materials, the
actuator 278 may be pressed by way of deforming the fabric and applying pressure to
the underlying actuator 278. By pivoting the telescopic foldable towing handle 186
at the pivot joint assembly 230, the detachable transport system 102 may be collapsed
at the middle portion 116 as shown and described in connection with Figs. 3B-3D. This
may allow the detachable transport system 102 to be easily transported, e.g., carried,
or stowed within a luggage piece 104. While a single pivot joint assembly 230 is illustrated
in connection with the telescopic foldable towing handle 186 Figures 5A-5G, multiple
pivot joint assemblies may be provided with the telescopic foldable towing handle
186 in order to provide multiple regions of folding and telescoping action. In some
implementations, one or more pivot joint assemblies 230 configured for folding but
not telescoping may be provided along with a telescopic foldable towing handle 186.
[0128] Turning to Fig. 6, another implementation of the detachable transport system 340
may include a first and a second soft sided enclosure 342, 344 with first and second
releasable attachment members 346, 348, respectively, that may releasably join to
a luggage piece with corresponding releasable attachment members. The first soft sided
enclosure 342 may be similar to the upper region 112 of the detachable transport system
102 described above in connection with Figs. 1A-2F and may receive the handle 358
in the handle housing when the handle 358 is in the retracted position. The second
soft sided enclosure 344 may be similar to the lower region 114 of the detachable
transport system 102 of Figs. 1A-2F and may carry one or more wheels 360, wheel housings
362 and stabilizing flanges 364. A foldable towing handle 354 may be arranged within
and may extend between the fist and second soft sided enclosures 342, 344. A pivot
joint assembly 356 of the foldable towing handle 354 may be used to fold the detachable
transport system 340 at the pivot joint assembly 356 and may be arranged between the
soft sided enclosures 342, 344. The detachable transport system 340 of Fig. 6 may
include the flexible strap 202 shown in Figs. 3A-3D for joining the upper and lower
regions 350, 352 when the pivot joint assembly 356 is in the folded state. In some
implementations, the foldable towing handle 354 of Fig. 6 may be the telescopic foldable
towing handle 186 shown in Figs. 5A-5G.
[0129] Turning to Fig. 7, in some implementations, the luggage piece 104 shown in Fig. 1A
may be used in combination with a detachable cover 400 having a similar configuration
to the contoured or hourglass shaped soft sided compartment of the detachable transport
system 102 but the detachable cover 400 may be constructed without wheels 130, wheel
housings 132, stabilizing flanges 134 and a handle 126. In some implementations, both
the detachable cover 400 and the detachable transport system 102 may be provided with
a luggage piece 104 in the luggage transport system. When the detachable transport
system 102 is not in use, the detachable cover 400 may be releasably joined to the
luggage piece 104 and vice versa. The detachable cover 400 may be constructed of durable
materials such as durable fabrics (e.g., nylon) or durable coatings (e.g., polymer
coatings) and may serve as a protection layer when joined to the luggage piece 104.
[0130] Turning to Figs. 8A and 8B, illustrated are snap closures 170 (Fig. 8A) and hook
and loop closures 172 (Fig. 8B) that may serve as releasable attachment members 136,
138. The snap 170 and hook and loop closures 172 may be used as an alternative to
or in addition to the zipper assemblies illustrated in connection with the detachable
transport systems 102 and luggage pieces 104. In addition, the releasable attachment
members 170, 172 may be used to join opposing panels 148, 150, 152, 154 of the luggage
piece 104 such as at the central region of the luggage piece 104.
[0131] With reference to Figs. 9A and 9B, one example of an alternative example of a closure
panel 402 will now be described. With reference to Fig. 9A, each of four zipper closure
mechanisms that collectively secure the luggage piece may include a zipper track or
tape, a zipper slider 406, and a zipper pull tab 408. The zipper sliders 406 may each
include one or more hasps or apertures 410 through which, as described below, a lock
or cable 412 may be inserted to hinder movement of the zipper pull tabs 408. In other
examples, the zipper pull tabs 408 may each have one or more hasps or apertures for
a similar purpose. In general, any one or more of the zipper sliders 406 or zipper
pull tabs 408 may include one or more hasps or apertures. In other embodiments, however,
none of the zipper sliders 406 and/or none of the zipper pull tabs 408 may include
hasps or apertures operable to receive a lock or a cable 412.
[0132] Even though the zipper sliders 406 or pull tabs 408 may include hasps or apertures
410 to receive a lock or a cable 412, it may not always be necessary or advisable
to secure access to the interior of the luggage piece with a lock 412 or similar mechanism.
For example, if the luggage case will not be subject to or handled by untrustworthy
persons , it may be inconvenient to secure the zipper closure mechanisms with a lock
412 or other mechanism. In these circumstances, however, it is generally still advantageous
for the luggage case to remain in a generally closed configuration during transport
and/or handling so that the inner compartment is not exposed by the zipper closure
mechanisms unintentionally unzipping. Therefore, it may be desirable for the closure
panel to provide some non-locking securing functionality - e.g., a functionality that
assists in maintaining the zipper closure mechanisms in a closed position, but that
can be overcome without the need to unlock a mechanism by entering a combination,
using a key, or the like. To this end, a securing mechanism 414 may be provided on
the upper and lower panels 416, 418 in some but not all examples.
[0133] With reference to Fig. 9B, one half of the securing mechanism 414 may be coupled
to the narrow terminal end of the upper panel 416, and the other half of the securing
mechanism 414 may be coupled to the narrow terminal end of the lower panel 418. The
securing mechanism 414 selectively couples the respective terminal ends together such
that if the zipper closure mechanisms come partially or fully unzipped, the terminal
ends of the upper and lower panels 416, 418 are held in a closed configuration. In
some examples, either one type of securing mechanism 414 may be used, or a combination
of two or more types of securing mechanisms 414 may be used. For instance, and as
described herein, hook-and-loop fastener structure 420, 422 may be used, independently
or in conjunction with a snap structure 424, 426.
[0134] With reference to Fig. 9B, material with hooks 420 (one-half of a hook-and-loop closure
mechanism) and also the receiving portion 424 of a snap are coupled to a tab extending
from the narrowing terminus of the upper panel 416, and are configured to face outwardly
of the internal compartment. These features are, together or separately, one portion
of the securing mechanism 414. Material with loops 422 (the other half of a hook-and-loop
closure mechanism) and the protruding portion 426 of the snap are coupled to the underside
of the terminal end of the lower panel 418 to form the other portion of the securing
mechanism 414. This other portion faces toward the inner compartment, and thus also
towards the first portion of the securing mechanism 414. With reference to Fig. 9A,
the two portions or halves of the securing mechanism 414 may be joined by coupling
the receiving and protruding portions 424, 426 of the snap and the coupling the hooks
420 and loops 422, such that the panels 416, 418 are hindered from accidentally moving
away from each other and exposing the compartment.
[0135] With reference to Fig. 9B, the two halves of the securing mechanism 414 may be separable
from one another by pulling the two portions apart from each other to disengage the
hook-and-loop material 420, 422, as well as the snap structure 424, 426, allowing
the upper and lower panels 416, 418 to fully open when the respective zipper closure
mechanisms are unzipped. Advantageously, the two halves or portions of the securing
mechanism 414 in some examples, as illustrated in Fig. 9B, may be entirely concealed
by the upper and lower panels 416, 418 when the two halves are joined together.
[0136] With reference now to Fig. 10, and referring back to Fig. 9A, a lock 412 may be used
in connection with the four zipper securing mechanisms. The lock 412 may take many
forms, and as illustrated in Fig. 10, may take the form of cable 428 coupled to a
semi-circle base portion 430. The cable 428 may include two end portions, and one
end may or may not be permanently coupled to the base portion 430. The diameter of
the cable 428 and end stops may generally be less than the diameter of any hasps or
apertures 410 in the zipper sliders 406 or zipper pull tabs 408 - for example, the
cable diameter may be approximately 50% the diameter of the hasps or apertures 410
in some examples. One end of the cable 428 may be selectively released and secured
from the base portion 430, as explained below.
[0137] The base portion 430 of the lock 412 may include a locking mechanism such as a combination
dial system, and may selectively release and secure one or both ends of the cable
428. Additionally or alternatively, the base portion 430 may include a tumbler lock
configured to receive a key. In some examples, two or more locking mechanisms may
be provided to, for example, allow security screening agencies to selectively disable
the lock and gain access to the enclosed volume of the luggage piece.
[0138] With reference to Figs. 11A through 11E, the detachable transport system may include
a support member 440, 440' operable to help support the luggage to stand on one end
in an upright position. The support member 440 may include two bosses 442, 442' coupled
to or through the bottom surface 444, 444' of the duffle case. Each boss 442, 442'
defines a recess 446, 446' therein that retractably receives an end of an extension
bar 448, 448'. Each boss 442, 442' may be coupled to or through the bottom surface
444, 444' by one or more fasteners 450, and may be coupled to an inner frame (e.g.,
the telescoping handle system, the bottom panel 456, the bottom frame 458, or the
like) of the detachable transport system for stability. The bosses 442, 442' may generally
be positioned between but adjacent to the wheel housings 452, 452' to provide a relatively
wide support base for the luggage. The bosses 442 may be positioned approximately
in the middle of the bottom panel of the duffle case, such as shown in Figs. 11A and
11B. The bosses 442' may be positioned near a front edge of the duffle case, such
as shown in Figs. 11C and 11D. The extension bar 448, 448' is generally U-shaped,
with a support portion extending between two free legs. Each leg defines an end movably
received in the recess 446, 446' in a respective boss 442, 442'. The extension bar
448, 448' may be metal, plastic, or another suitable material. Two cylindrical sleeves
may be positioned along the length of the support portion and between the intersection
of the support portion and the two legs. The sleeves engage the support surface (e.g.
floor) when the luggage case is stood on end and upright. When standing on its end,
the duffle rests on its two wheels and the extension bar 448, 448' and possibly also
the bosses 442, 442', for stability. While the extension bar may be U-shaped in some
examples, as illustrated in Figs. 11A through 11D, but may be semi-circular, rectilinear,
or have dual curves, or take on a variety of shapes.
[0139] In some examples, and with reference to Figs. 11B and 11E, the extension bar 448,
448' may be retractable into and extendible from the recesses 446, 446' defined in
the bosses 442, 442'. In this manner, the support system 440, 440' may assist in selectively
expanding or enlarging the footprint of the luggage case, preferably when the luggage
case is to be stood on end, to better distribute the weight of the luggage case when
the luggage case is in a vertical position. In this extended orientation, the extension
bar 448, 448' may be fully extended (Fig. 11A, 11C), partially extended, or fully
retracted (Fig. 11B, 11D). The extension bar 448, 448' may extend beyond the front
edge of the duffle in order to provide improved support against tipping. The amount
the support portion of the extension bar 448, 448' is positioned beyond the front
edge of the duffle case may be from none, to approximately 50% of the length of the
legs, to possibly more.
[0140] As noted above, and in reference to Fig. 11E, the extension bar 448, 448' may be
retracted into the bosses 442, 442' to reduce the amount of extension when, for example,
the luggage case is placed on its side. In those examples where the extension bar
448, 448' is extendible/retractable, it may lock or be held in either or both of its
extended and retracted positions by a détente structure 454 formed between the leg
and the recess 446, 446'. Other types of retention structure may also be used, such
as, locking pins, latches, and so forth. The extension bar 448, 448' may selectively
lock or be held in the retracted position so as to not interfere with luggage handling
or storage, and may selectively lock into the extended position so as to not move
to the collapsed position when the duffle is positioned vertically. One example of
a détente structure 454 includes an annular groove formed around the interior surface
of the recess 446, 446', which receives a resilient protrusion (e.g. a spring) extending
from the outer side wall of the leg inserted into the recess 446, 446'. When the protrusion
reaches the groove, the protrusion resiliently extends into the groove and helps position
the extension bar 448, 448' in that position. The engagement may be overcome by manual
force to cause the protrusion to collapse back to the surface of the leg and allow
the leg to move within the recess 446, 446'.
[0141] Turning to Fig. 12, in some examples, such as those with a relatively small luggage
piece, the support member 460 may not include bosses or an extension bar, but may
instead be a single plastic foot positioned along the width of the bottom surface
462, such as being centered from side to side as shown.
[0142] With reference now to Fig. 13, in some examples, such as those with a relatively
large luggage piece, the luggage piece may not be detachable from the rest of the
transport system. In these embodiments, there may be no releasable attachment member
(e.g., a zipper) 464 that couples the luggage piece to the transport system.
[0143] The structures and functions of the detachable transport system implementations may
be used interchangeably to form alternative implementations, as would be appreciated
by those skilled in the art.
[0144] While the detachable transport systems are described as used with a luggage piece
configured as a soft sided duffel bag, the detachable transport systems could be used
with any type of luggage or with backpacks or other bags. The luggage pieces may have
hard or soft sides and may be formed from any type of material or construction used
to form luggage pieces, including, but not limited to, fabrics (e.g., nylon), plastics
(e.g., acrylonitrile butadiene styrene ("ABS"), polycarbonate, polypropylene, polyethylene,
etc.), natural materials (e.g., plywood), metals, or some combination thereof. The
luggage pieces may further include structures, such as lining or internal panels,
positioned within the main enclosed space that divide it into two or more compartments.
The luggage pieces may also include any of the following: one or more carry handles
to lift or otherwise move the luggage piece, edge piping to help protect the outer
surface of the luggage piece from scuffs and abrasions, and at least one perimeter
zipper to access the main enclosed space and any pockets or secondary or supplemental
enclosed spaces.
[0145] All directional references (e.g., upper, lower, upward, downward, left, right, leftward,
rightward, top, bottom, above, below, vertical, horizontal, clockwise, and counterclockwise)
are only used for identification purposes to aid the reader's understanding of the
implementations of the present invention, and do not create limitations, particularly
as to the position, orientation, or use of the invention unless specifically set forth
in the claims. Connection references (e.g., attached, coupled, connected, joined,
and the like) are to be construed broadly and may include intermediate members between
a connection of elements and relative movement between elements. As such, connection
references do not necessarily infer that two elements are directly connected and in
fixed relation to each other.
[0146] In some instances, components are described with reference to "ends" having a particular
characteristic and/or being connected with another part. However, those skilled in
the art will recognize that the present invention is not limited to components which
terminate immediately beyond their points of connection with other parts. Thus, the
term "end" should be interpreted broadly, in a manner that includes areas adjacent,
rearward, forward of, or otherwise near the terminus of a particular element, link,
component, part, member or the like. In methodologies directly or indirectly set forth
herein, various steps and operations are described in one possible order of operation,
but those skilled in the art will recognize that steps and operations may be rearranged,
replaced, or eliminated without necessarily departing from the spirit and scope of
the present invention. It is intended that all matter contained in the above description
or shown in the accompanying drawings shall be interpreted as illustrative only and
not limiting. Changes in detail or structure may be made without departing from the
spirit of the invention as defined in the appended claims.
