TECHNICAL FIELD
[0001] The present disclosure relates to inflatable products. More particularly, the present
disclosure relates to an inflatable bed with a covering.
BACKGROUND
[0002] Inflatable beds, and other inflatable products on which people lie down and/or rest,
are favored by consumers due to the advantages of being lightweight, storable, portable,
convenient to use, and the like. During use, in order to ensure comfort, improve the
thermal insulation property, and meet other needs, consumers typically use a variety
of coverings, such as pads, blankets, and the like, on the contact surface of the
inflatable bed. However, these coverings can easily slip, slide, or otherwise become
removed from the contact surface in the absence of additional fastening devices. Accordingly,
it can be difficult to ensure and maintain the improved comfort provided by these
coverings.
[0003] Some inflatable beds include inflatable bodies with inflatable chambers, as well
as their own coverings, which are laid over the inflatable bodies in a fixed or detachable
manner. For these inflatable beds, the coverings can provide an important influence
on the diversity, aesthetics, and comfort of the beds. However, the layered structure
of the covering, the selection of materials, the production process, the connection
of the covering to the inflatable body with the inflatable chambers, etc. can be difficult
and costly for manufacturers of inflatable beds, and there is accordingly still a
need for further improvements.
SUMMARY
[0004] It is an object of the present disclosure to provide an improved inflatable bed with
a covering.
[0005] According to an aspect of the disclosure, an inflatable bed includes: an inflatable
body having a top sheet, a bottom sheet, a lateral confining sheet connected to the
top sheet and the bottom sheet; a covering connected to the inflatable body and disposed
over the top sheet. The covering includes at least one outer layer and an inner layer
connected to the outer layer. A periphery of the at least one outer layer is fixedly
or detachably connected to the inflatable body, and the periphery of the at least
one outer layer extends to a periphery of the top sheet.
[0006] Compared with the existing inflatable beds, the inflatable bed with a covering according

a bottom edge of the lateral confining sheet, and the inflatable body further includes
an extension belt that extends out from the top edge of the lateral confining sheet,
and the periphery of the outer layer is connected to the extension belt.
[0017] In some optional forms, the extension belt and the lateral confining sheet are made
from the same sheet of material and define a unitary structure as one piece.
[0018] In some optional forms, the extension belt is made from a separate sheet material
and is connected to the lateral confining sheet by welding or other connection methods.

according to specific circumstances.
First Embodiment
[0032] FIG. 1 to FIG. 5 show an inflatable bed 10 and components thereof, according to a
first embodiment of the present disclosure. In the illustrated embodiment, the inflatable
bed 10 is substantially rectangular on the whole. However, this is merely illustrative,
and the shape of the inflatable bed 10 is not limited in the present disclosure. In
some variants, the inflatable bed 10 may also be arranged in any other appropriate
shapes, such as a substantially circular shape, a substantially oval shape, and various
regular or irregular polygonal shapes.
[0033] As shown in FIG. 1 to FIG. 5, the inflatable bed 10 includes an inflatable body 100
and a covering 200 fixedly or detachably connected to the inflatable body 100. According
to an aspect of the disclosure, and as well shown in figures 4 and 5, the inflatable
body 100 includes a top sheet 101, a bottom sheet 102, a lateral confining sheet 103,
an extension belt 104, a plurality of first tensioning members 105, and a plurality
of second tensioning members 106. The inflatable body 100 may also be referred to
as an inflatable chamber, and may include various arrangements of internal spaces
or chambers that may be inflated and deflated as desired to adjust the comfort of
the inflatable bed 10. The inflatable body 100 may be inflated via a variety of inflation
processes. It will be appreciated that various aspects of the disclosure may also
be applicable to other types of beds or leisure structures not explicitly disclosed
herein.
[0034] The top sheet 101 may be considered to be the upper portion or top portion of the
inflatable body 100. The bottom sheet 102 may be considered to be a lower portion
or bottom portion.
[0035] The lateral confining sheet 103, or more easily lateral sheet, extends generally
around the periphery of the inflatable bed 10 and defines the lateral periphery of
the inflatable body 100. The extension and profile of the lateral confining sheet
103 essentially defines the shape and profile of the inflatable bed 10. For instance,
the lateral sheet may extend around in rectangular manner to define a rectangular
bed shape, or may extend in a circular path to define a circular bed shape. The lateral
confining sheet 103 is shown extending in a generally vertical direction, extending
between the top sheet 101 and the bottom sheet 102. However, the lateral sheet 103
may also extend in a generally angled direction relative to the vertical direction.
For instance, the top sheet 101 may be smaller than the bottom sheet 102, with the
lateral confining sheet 103 tapering inward, for example.
[0036] The periphery of the top sheet 101, such as its outer edge, is connected to the periphery
of the bottom sheet 102, such as its outer edge, by way of the lateral confining sheet
103. More specifically, the periphery of the top sheet 101 is connected to a top edge
of the lateral confining sheet 103 by, for example, welding, and the periphery of
the bottom sheet 102 is connected to a bottom edge of the lateral confining sheet
103 by, for example, welding, such that the top sheet 101, the bottom sheet 102, and
the lateral confining sheet 103 jointly define the inflatable body 100, having one
or more inflatable chambers therein.
[0037] The extension belt 104 extends upwards from the top edge of the lateral confining
sheet 103, and is provided and configured to be connected to the covering 200. More
specifically, the length/height of the extension belt 104 extending upwards from the
top edge of the lateral confining sheet 103 may be 1 cm to 4 cm, preferably about
2 cm, thereby providing a sufficient operating space to a manufacturer to connect
the extension belt 104 to the covering 200. It will be appreciated, however, that
other sizes and lengths/heights of the extension belt 104 may be used.
[0038] In some embodiments, the extension belt 104 and the lateral confining sheet 103 are
made from the same sheet of material. Put another way, the sheet of material of the
confining sheet 103 extends upwards from the bottom sheet 102 toward the top sheet
101 and beyond the top sheet 101, with the material extending beyond the top sheet
101 being the extension belt 104.
[0039] In some other embodiments, the extension belt 104 is made from a separate sheet of
material and is connected to the top edge of the lateral confining sheet 103 by welding.
The extension belt 104 in these embodiments may also be attached to the top sheet
101. The separate extension belt 104 may also be attached in other ways.
[0040] With reference to the FIGS. 4 and 5, the plurality of first tensioning members 105
and shown extending parallel along a width direction of the inflatable body 100 and
are disposed uniformly within the inflatable body 100 along a length direction of
the inflatable body 100. However, it will be appreciated that the tensioning members
105 may extend in other directions of the illustrated shape of the inflatable body,
for instance perpendicular to the direction illustrated, or at an oblique angle from
the direction illustrated. Additionally, it will be appreciated that other shapes
of the inflatable body may include different orientations of the tensioning members
105. The first tensioning members 105 may also be arranged at unequal spacing.
[0041] A top edge of each first tensioning member 105 of the plurality of first tensioning
members 105 is connected to the top sheet 101 by, for example, welding, and a bottom
edge of each first tensioning member 105 of the plurality of first tensioning members
105 is connected to the bottom sheet 102 by, for example, welding, so as to tension
the inflatable body 100 after inflation. Put another way, as the inflatable body is
inflated and expends, the outward forces caused by the inflation will put the tensioning
members 105 in tension, and will limit the outward/upward/downward expansion of the
top and bottom sheets 101, 102, thereby maintain a generally flat surface and shape
at the top and bottom of the inflatable body.
[0042] With continued reference to FIGS. 4 and 5, the inflatable bed 10 further includes
second tensioning members 106 disposed within the inflatable body 100. In one aspect,
an outer edge of each second tensioning member 106 of the plurality of second tensioning
members 106 (also referred to as diagonal tensioning members) is connected to the
lateral confining sheet 103 by, for example, welding, and an inner edge of each second
tensioning member 106 of the plurality of second tensioning members 106 is connected
to the top sheet 101 or the bottom sheet 102 by, for example, welding, so as to further
optimize the mechanical properties of the inflatable body 100. Each second tensioning
member 106 of these second tensioning members 106 includes at least one air hole 1061
to avoid dividing the inflatable body 100, such that inflation air can reach the internal
chamber defined in the generally triangular space defined between the top sheet 101
or bottom sheet 102, lateral confining sheet 103, and second tensioning member 106.
It will be appreciated that the inflatable body 100 may still be divided into multiple
chambers, but as illustrated is formed as a single main inflation chamber having fluid
communication past/through the first and second tensioning members 105, 106, such
that inflation air may inflate the space delimited by the top sheet 101, bottom sheet
102, and lateral confining sheet 103.
[0043] In the illustrated embodiment, the inflatable body 100 includes two second tensioning
members 106, one of the second tensioning members 106 connecting the lateral confining
sheet 103 to the top sheet 101, and the other second tensioning member 106 connecting
the lateral confining sheet 103 to the bottom sheet 102, so as to form a three-layer
structure within the inflatable body 100. In some implementation variants, the inflatable
body 100 may include a greater number of second tensioning members 106 to form a more-layer
structure.
[0044] The second tensioning members 106 may extend continuously along the upper and lower
periphery of the inflatable body 100, in one aspect, or may be separate and extend
along distinct sides/edges of the inflatable body (such as using four tensioning members
along all four upper edges of a rectangular shape and four tensioning members along
all four bottom edges of a rectangular shape). Other combinations may also be used,
such as a tensioning member 106 extending continuously along some but not all of the
edges. The length and arrangement of the tensioning members 106 may be different along
the upper periphery relative to the lower periphery.
[0045] With reference again to the first tensioning members 105, it is to be understood
that the shape of the first tensioning members 105 is not limited in the present disclosure.
These tensioning members 105 may be C-shaped tensioning members, Y-shaped tensioning
members, Z-shaped tensioning members, square tensioning members, string-type tensioning
members, and any other tensioning members that are suitable for the inflatable body
100, and only need to satisfy sufficient connection strength. Similarly, the second
tensioning members 106 may have other shapes.
[0046] In one aspect, taking the top of the inflatable body 100 as an example, in particular
as shown in the exploded view of FIG. 3, the first tensioning members 105 (shown extending
across the width of the inflatable body) are connected to the top sheet 101 to form
a plurality of first weld lines 1011 that are parallel to each other, and the second
tensioning members 106 are connected to the top sheet 101 to form a ring-shaped second
weld line 1012, the second weld line 1012 encircling these first weld lines 1011 and
generally defining an actual usable area of the inflatable body 100 for a person to
lie down. It is to be understood that the bottom of the inflatable body 100 may be
of the similar structure.
[0047] It will be appreciated that other arrangements and orientations of the first tensioning
members 105 and the second tensioning members 106 may result in correspondingly different
shapes of the weld lines 1011 and 1012.
[0048] In one aspect, the actual usable area within the second weld line 1012 may be recessed,
such that the outer peripheral area of the top sheet 101 slopes downward and inward,
as shown in FIG. 3. In another aspect, the upper surface of the top sheet 101 may
be generally flat. It will be appreciated that the degree of the slope or the size
of the area within the second weld line 1012 may be varied.
[0049] The top sheet 101, the bottom sheet 102, the lateral confining sheet 103, the extension
belt 104, the plurality of first tensioning members 105 and the plurality of second
tensioning members 106 of the inflatable body 100 are preferably made of a weldable
polymer material, and for example, may be made of one or a combination of more of
polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU), polyurethane
(PU), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), nylon
and other suitable polymer materials.
[0050] The inflatable body 100, in a preferred form, has a single internal inflatable space
defined therein, with the internal inflatable space being fluidly connected through
and around the internal tensioning members 105, 106, and inflatable via as little
as one inflation opening in a manner known in the art. However as described above,
the inflatable body 100 may also include multiple separate internal inflatable spaces
that are fluidically isolated. It will be appreciated that the present disclosure
may be applicable to a variety of internal support structures and arrangements of
inflatable spaces.
[0051] With reference now to the covering 200, the covering 200 covers at least partially
the inflatable body 100, preferably covers the entire top sheet 101 of the inflatable
body 100, and includes at least one outer layer 201, 202 capable of being in contact
with the human body and an inner layer 203 connected to the outer layer 201.
[0052] In the first embodiment, the covering 200 is a three-layer structure made by quilting.
More specifically, the covering 200 comprises a first outer layer 201 oriented upwards,
or defining the top of the covering 200, and a second outer layer 202 oriented downwards
(located on the backside of the illustrated covering 200, see for example figure 9).
[0053] In one aspect, the periphery or outer edge of the first outer layer 201 is connected
to the periphery or outer edge of the second outer layer 202 by sewing, and the inner
layer 203 is disposed between the first outer layer 201 and the second outer layer
202.
[0054] In one aspect, a plurality of quilting threads 2011 are crosswise distributed diagonally
and are connected to both the first outer layer 201 and the second outer layer 202
by quilting. The distribution manner of the plurality of quilting threads 2011 is
not restrictive and may be separately determined according to the appearance of the
covering 200. For instance, the quilting threads 2011 can be arranged in a grid and
extend parallel to the edges of the inflatable body 100. The quilting threads 2011
may be evenly spaced or unevenly spaced.
[0055] In one aspect, the inner layer 203 generally completely fills the space defined between
the first and second outer layers 201, 202. The quilting threads 2011 secure the first
and second outer layers 201, 202 with the internal inner layer 203.
[0056] In one aspect, the outer layer 201, 202 of the covering 200 is a fabric layer, and
for example, is made of one or a combination of more of cotton fiber, wool fiber,
silk fiber, hemp fiber, regenerated fiber, polyester fiber, polyamide fiber, polyacrylonitrile
fiber, polyvinyl alcohol fiber, polypropylene fiber, polyurethane fiber, and/or inorganic
fiber. The inner layer 203 of the covering 200 is also a fabric layer, and for example,
is made of one or a combination of more of cotton fiber, wool fiber, viscose fiber,
acetate fiber, polyester fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl
alcohol fiber, polypropylene fiber, and/or polyurethane fiber.
[0057] In the first embodiment, the periphery of the outer layer 201 of the covering 200
extends to the periphery of the top sheet 101, and is detachably connected to the
extension belt 104 of the inflatable body 100, for example, by a detachable mechanism
or zipper 300. More specifically, with reference to FIG. 3, a first half zipper 301
is sewn to a top edge of the extension belt 104, and a second half zipper 302 is sewn
to the periphery of the first outer layer 201 and/or the periphery of the second outer
layer 202 of the covering 200, so that the two half zippers 301, 302 are engaged to
achieve a detachable connection. Thus, a user can mount the covering 200 onto the
inflatable body 100 or remove the same from the inflatable body 100 conveniently by
means of the zipper 300, and both the first outer layer 201 and the second outer layer
202 of the covering 200 can be arranged upwards or outwardly facing when attached;
that is, the covering 200 can be used double-sided. In some implementation variants,
the periphery of the outer layer 201, 202 of the covering 200 may also be detachably
connected to the extension belt 104 of the inflatable body 100 by other detachable
connecting mechanisms such as a reclosable fastener or a snap fastener.
[0058] Furthermore, in the first embodiment, the covering 200 is not limited to the quilted
covering illustrated, but the covering 200 may also be, for example, sponge composite
fabric, sandwich mesh fabric, or any other comfortable coverings having similar process
principles and suitable for use with the inflatable bed 10.
[0059] In one aspect, the covering 200 is connected to the inflatable body 100 around substantially
the entire outer periphery of the covering 200 and the inflatable body 100. In the
various figures throughout the disclosure, the covering 200 is shown in a broken section,
with a corner of the covering 200 removed to illustrate the layered nature of the
covering 200 as well as to illustrate the internal features of the inflatable body
100 in some instances. It will be appreciated that these figures are not intended
to limit the covering 200 (or the inflatable body 100) to the illustrated partial
shape. Indeed, FIG. 1 clearly illustrates the covering 200 overlapping and covering
substantially the entire surface area of the top sheet 101 and the inflatable body
100.
[0060] The zipper 300 or other connection type, detachable or fixed, likewise extends substantially
around the entire periphery, as shown in FIG. 1. However, it will be appreciated that
the zipper 300 may also be arranged to extend around less than substantially the entire
periphery, for example as illustrated in the partial cutaway views or other partial
extensions around the periphery. In such instances, the covering 200 may still be
maintained and secured in place relative to the inflatable body 100.
Second Embodiment
[0061] FIG. 6 and FIG. 7 show an inflatable bed 10 and components thereof, according to
a second embodiment of the present disclosure. It can be understood that an inflatable
body 100 and a covering 200 of the inflatable bed 10 in the second embodiment are
of an overall structure similar to that in the first embodiment, so that the similarity
to the first embodiment may be understood with the help of the above detailed descriptions,
and will not be repeated in this section. For instance, the tensioning members 105,
106, and quilting threads 2011, and their various possible arrangements and orientations
may also be used with the second embodiment, and the various possible shapes and arrangements
of the inflatable body and its constituent parts may also be used.
[0062] As shown in FIG. 6 and FIG. 7, the difference from the inflatable bed 10 of the first
embodiment is that, in the inflatable bed 10 of the second embodiment, the periphery
of an outer layer 201 of the covering 200 extends to the periphery of a top sheet
101 and is fixedly connected to an extension belt 104 of the inflatable body 100,
rather than being detachably connected via the zipper 300 or other detachable attachment
mechanism. For example, the periphery of a first outer layer 201 of the covering 200,
the periphery of a second outer layer 202 of the covering 200, and a top edge of the
extension belt 104 of the inflatable body 100 are welded together by high-frequency
welding. It will be appreciated that other fixed attachment methods that joins these
components may also be used.
[0063] Thus, in the second embodiment, the outer layers 201, 202 of the covering 200 is
a weldable polymer material layer, and for example, is made of one or a combination
of more of polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU), polyurethane
(PU), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), nylon
and other suitable polymer materials.
[0064] However, it will be appreciated that other materials may also be used in the case
of other fixed attachment methods.
Third Embodiment
[0065] FIG. 8 and FIG. 9 show yet another structure of a covering 200 of an inflatable bed
10 according to a third embodiment of the present disclosure. It can be understood
that an inflatable body 100 of the inflatable bed 10 in the third embodiment may be
of an overall structure similar to that in the first embodiment or the second embodiment,
and accordingly, can be understood with the help of the above detailed descriptions,
and will not be repeated in detail this section. As in the second embodiment, the
third embodiment may include any and/or all of the various arrangement and orientation
options of the constituent parts of the inflatable bed 10 or the first and second
embodiment, so long as such options do not conflict with the details of the third
embodiment.
[0066] As shown in FIG. 8 and FIG. 9, in the inflatable bed 10 of the third embodiment,
the covering 200 is a three-layer structure made by ultrasonic welding. More specifically,
the covering 200 includes a first outer layer 201 oriented upwards and a second outer
layer 202 oriented downwards. The periphery of the first outer layer 201 is connected
to the periphery of the second outer layer 202, and an inner layer 203 is disposed
between the first outer layer 201 and the second outer layer 202. A plurality of third
weld lines 2012 are regularly distributed diagonally and are welded to the first outer
layer 201 and the second outer layer 202 by ultrasonic welding, that is, by ultrasonic
vibration. High temperature is locally generated in the materials to be processed
to melt contact surfaces, and the contact surfaces are melted and joined under a certain
pressure by way of a pressing die 400 (see FIG. 9). The distribution manner of the
plurality of third weld lines 2012 is not restrictive and may be separately determined
according to the appearance of the covering 200. The weld lines 2012 are distributed
at various locations across the covering 200, similar to quilting, to join together
the outer layers 201, 202 and the inner layer 203, disposed within, such that the
inner layer 203 will remain relatively in place within the two outer layers 201, 202
and to avoid or limit bunching of the inner layer 203.
[0067] In the third embodiment, the first outer layer 201 and the second outer layer 202
of the covering 200 may be fabric layers, and for example, may be made of one or a
combination of more of cotton fiber, wool fiber, silk fiber, hemp fiber, regenerated
fiber, polyester fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl alcohol
fiber, polypropylene fiber, polyurethane fiber, and/or inorganic fiber. Preferably,
the fabric layers contain no less than 30% of chemical fibers to enhance the strength
of connection. The inner layer 203 of the covering 200 is also a fabric layer and,
for example, is made of one or a combination of more of cotton fiber, wool fiber,
viscose fiber, acetate fiber, polyester fiber, polyamide fiber, polyacrylonitrile
fiber, polyvinyl alcohol fiber, polypropylene fiber, and/or polyurethane fiber.
[0068] In addition, in the third embodiment, the first outer layer 201 and the second outer
layer 202 of the covering 200 may also be polymer material layers, and for example,
may be made of one or a combination of more of polyvinyl chloride (PVC), thermoplastic
polyurethane elastomer (TPU), polyurethane (PU), polypropylene (PP), polyethylene
(PE), polyethylene terephthalate (PET), nylon and other suitable polymer materials.
[0069] In the case that both the first outer layer 201 and the second outer layer 202 are
fabric layers, the periphery of the first outer layer 201 and/or the periphery of
the second outer layer 202 may be sewn with a detachable connecting mechanism 300
(such as that shown in FIGS. 1-4 and 8) such as a zipper, a reclosable fastener, or
a snap fastener, for example, to be detachably connected to the extension belt 104
of the inflatable body 100. In the illustrated embodiment, a second half zipper 302
is sewn to the periphery of the first outer layer 201 and/or the periphery of the
second outer layer 202 to be detachably connected to a first half zipper (as shown
in FIGS. 1-4) on the extension belt 104 of the inflatable body 100.
[0070] In the case that the first outer layer 201 and the second outer layer 202 are polymer
material layers, the periphery of the first outer layer 201 and/or the periphery of
the second outer layer 202 may be detachably connected to the extension belt 104 of
the inflatable body 100 by sewing the above-described detachable connecting mechanism
300, or may be fixedly connected to the extension belt 104 of the inflatable body
100, for example, by high-frequency welding, similar to the second embodiment. Other
suitable fixed attachment methods may also be used.
[0071] Of course, when the layers 201, 202 are fabric layers, they may also be fixedly connected
to the extension belt 104 in any suitable manner.
[0072] It is to be understood that the ultrasonic welding process may be used to weld polymer
materials or fiber fabrics. Compared with the undesirable situations such as cracks,
broken stitches, and skipping stitches, that may occur in the covering 200 manufactured
by the quilting process, the covering 200 manufactured using the ultrasonic welding
process according to the third embodiment is able to avoid these undesirable situations
while improving the production efficiency, optimizing the appearance and comfort of
the product, and enriching the diversity of the product. However, it will be appreciated
that the various aspects of the present disclosure may still provide the apparent
improvements when quilting is used for the covering 200, as in FIGS. 1-7.
Fourth Embodiment
[0073] FIG. 10 shows a structure of a covering 200 of an inflatable bed 10 according to
a fourth embodiment of the present disclosure. It can be understood that an inflatable
body 100 of the inflatable bed 10 in the fourth embodiment may be of an overall structure
similar to that in the above described embodiments, and accordingly, can be understood
with the help of the above detailed descriptions, and will not be repeated in this
section.
[0074] As shown in FIG. 10, the main difference between the inflatable bed 10 in the fourth
embodiment and the inflatable bed 10 in the third embodiment is that the covering
200 is a two-layer structure made by ultrasonic welding, rather than the three layer
structure of the third embodiment. More specifically, the covering 200 includes a
single outer layer oriented upwards (i.e., a first outer layer 201 instead of first
and second layers 201, 202 as in the third embodiment), and an inner layer 203 is
connected to a bottom surface of the single outer layer 201 by ultrasonic welding
along the third weld lines 2012. The bottom of the inner layer 203 in this embodiment
is not covered by another outer layer. The distribution manner of the third weld lines
2012, similar to those of the third embodiment, is not restrictive, and may be the
same or different as in the third embodiment, and may also be separately determined
according to the appearance of the covering 200, such as having a different pattern
or arrangement across the covering 200.
[0075] In the fourth embodiment, the outer layer 201 of the covering 200 is a polymer material
layer, and for example, is made of one or a combination of more of polyvinyl chloride
(PVC), thermoplastic polyurethane elastomer (TPU), polyurethane (PU), polypropylene
(PP), polyethylene (PE), polyethylene terephthalate (PET), nylon and other suitable
polymer materials; and the periphery of the outer layer 201 may be fixedly connected
to the extension belt 104 of the inflatable body 100, for example, by high-frequency
welding, so that the covering 200 cannot be detached from the inflatable body 100.
In addition, the inner layer 203 of the covering 200 is a fabric layer, and for example,
is made of one or a combination of more of cotton fiber, wool fiber, viscose fiber,
acetate fiber, polyester fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl
alcohol fiber, polypropylene fiber, or polyurethane fiber.
[0076] However, it will be appreciated that the covering 200 of the fourth embodiment may
also be attached to the inflatable body 100 via a detachable connection 300 similar
to those described above, such as a zipper, snaps, or the like. Unlike the three layer
covering 200, the two layer covering 200 of the fourth embodiment would not be used
as a reversible covering to provide the same type of material on the upper/outer surface
when installed regardless of orientation, because the inner layer 203 maybe different
than the single outer layer 201. However, the single outer layer 201 and inner layer
203 in this embodiment may be reversibly used in this arrangement to provide a user
with a choice of the type of the material that will be directed upwardly and outwardly.
Fifth Embodiment
[0077] Additionally, in a fifth embodiment and applicable for use with any of the above
embodiments and as illustrated in FIG. 11, the covering 200 and the inflatable body
100 may be connected in other ways. For example, the inflatable bed 10 may include
a connecting strip 500 extending around the perimeter of the covering 200, the connecting
strip 500 having an inner periphery 502 and an outer periphery 501, where the outer
periphery 501 of the connecting strip 500 is fixedly connected to the extension belt
104, and the inner periphery 502 of the connecting strip 500 is detachably connected
to the covering 200 having the detachable mechanism 300. For example, the inner periphery
502 may include zipper portion 301, and the cover 200 may include zipper portion 302,
similar to the arrangement described in the first embodiment. The connecting strip
500 has a width of roughly 2 to 3 cm, and may be disposed above the top sheet 101
and parallel to the top sheet 101.
[0078] As shown in FIG. 11, the connecting strip 500 extends inwardly from the extension
belt 104 along the contour of the upper surface of the inflatable bed 10 that is formed
by the internal tension members, such that the connecting strip slopes downward along
the upper surface. However, it will be appreciated that when the covering 200 is connected
to the connecting strip 500, the connecting strip 500 may be pulled more taught in
some arrangements.
[0079] The connecting strip 500 may accordingly extend inwardly from the outer edge of the
top sheet 101 and the extension belt 104 and overlap an outer portion of the top sheet
101. Thus, the overall coverage area or footprint of the covering 200 in this approach
is generally smaller than the overall coverage area of the top sheet 101 and thus
the covering does not completely cover the top sheet 101. The area that is not covered
by the covering 200 is covered by the connecting strip 500.
[0080] As shown in FIG. 11, the covering is illustrated similar to the covering 200 of the
embodiment of FIG. 8, but is smaller due to the reduced coverage area. It will be
appreciated that the covering may also be similar to those of the other embodiments
(such as those with quilting as illustrated in FIGS. 1-7). It will further be appreciated
that the connecting strip 500 may be used with the other embodiments, with the modification
of such embodiments being primarily directed to the difference in the size of the
covering 200 to accommodate the size of the connecting strip 500 that overlaps the
top sheet 101. In another aspect, the connecting strip 500 may be fixedly attached
to the covering 200 in a manner as described herein, for instance via welding.
[0081] With reference now to all of the above embodiments and their variants and possible
combinations of features, as can be seen from each of the above embodiments, compared
with the prior inflatable beds, the inflatable bed 10 with a covering 200 according
to the present disclosure has the advantages that the overall structure of the covering
200 is simple, and the covering 200 is convenient to manufacture and low in cost;
moreover, the outer layer 201, 202 of the covering 200 can be conveniently connected
to the inflatable body 100 of the inflatable bed 10 in a fixed or detachable manner,
so that the covering 200 will not slip during use and meets the need for good comfort.
[0082] As can be understood from the present disclosure, each of the various features shown,
described, or otherwise disclosed and apparent from the present disclosure may be
interchangeably used with each of the embodiments so long as such features do not
conflict.
[0083] The components and features described herein can be made of various other materials
including, but not limited to, polymer, rubber, metal, and other suitable materials
well known to those skilled in the art or a combination thereof. The described and
illustrated embodiments only show the optional shapes, dimensions and arrangements
of various components of the inflatable bed according to the present disclosure, which
are merely illustrative but not limiting, and other shapes, dimensions and arrangements
may be employed without departing from the scope of the present disclosure. Those
skilled in the art can easily make modifications, variants, and equivalents of these
embodiments on the basis of the disclosed content. For example, the illustrated or
described features as part of an embodiment can be used with another embodiment to
provide a further embodiment. The present disclosure is intended to cover these modifications,
variants, and equivalents.
