[0018] The present invention may provide a lavatory door with higher reliability than existing
bi-fold lavatory doors while maintaining space efficiency. Optionally, the invention
may be a saloon-type door. It will be appreciated by those of ordinary skill in the
art that a saloon-type door, also known in the art as cafe doors, may include two
opposing panels that open in the middle thereof and often use bidirectional hinges
that close the door regardless of which direction it is opened by incorporating springs
or other biasing members.
[0019] The door assembly disclosed herein may include a plurality of subsystems, including
the hinge and door stop mechanism, the lock and gap seal mechanism, and the door panels.
The hinge may provide a self-closing door that preferably allows up to and including
180 degree rotation each way. This is important so that the user is not boxed in when
exiting the lavatory if the door only opens 90 degrees outward into the aisle. Another
important design concern for the lavatory door was to allow egress in case of an emergency.
If the door only opens 90 degrees into the aisle when opened, this would block passage
through the aisle. A hinge design with 180 degree rotation allows a user to push the
panel until it is flat against the wall, allowing easy passage through the aisle in
case of emergency. The hinge assembly may include strips of material. Materials for
use in the hinge can include synthetic polymer fabrics such as ripstop nylon, ripstop
polyester, HDPE (High Density Polyethylene) and Nylon blends, and UHMWPE (Ultra High
Molecular Weight Polyethylene) fabric also known as Dyneema. These synthetic polymer
fabrics may have the necessary value ranges of strength and toughness to prevent the
door panel from sagging while also being able to flex 180 degrees without experiencing
plastic deformation or failure. Optionally, a DCF Hybrid UHMWPE material (Dyneema
mixed with polyester) is used due to its stiffness as well as flexibility.
[0020] In order for the hinge to function properly it may require that each side of the
hinge (wall and lavatory door panel) require a radius that is one half of the door
panel width. In order to self-close the door afterwards, magnets may be included between
the door panel and the frame to bring the door back to center after being opened.
Optionally, the magnets can be omitted. Optionally, one or two magnets may be placed
at the top or bottom of the panel that are strong enough to pull the door back to
center. Optionally, more than two magnets may be included. To prevent the closing
panels from brushing against a user, magnets may be inserted into the door and wall
panels that connect when the door is fully open on the opposite end of the closing
magnets giving them a mechanical advantage and allowing the door to stay open when
it is fully opened and then to close by itself once a close is initiated by the user
are used.
[0021] The lock or stop assembly may include a blade member or blocking member that resides
inside one of the door panels and runs most or all of the length of the panel. The
blade member may be connected to a four-bar linkage mechanism. The opposite door panel
may include a receiver into which the blocking member may be inserted when the door
is locked. The blocking member may block the doors from being opened. The receiver
can simply be a pocket cut or carved into the opposite door panel or can be an insert
that includes a pocket that is secured in the opposite door panel.
[0022] Optionally, the assembly may also include a detent assembly that provides a "feel"
for the user that that the lock assembly was either locked or unlocked. In other words,
the detent may provide a tactic indicator that the assembly is fully locked or unlocked.
Optionally, the detent assembly may include a bi-stable cam and spring mechanism.
[0023] The lock assembly may also include triangular brackets that pivotably attach to the
long vertical linkage that includes the user handle and bar members or linkages that
apply the direct force to the blocking member in order to move it. It will be appreciated
that the length of two legs of the triangle may be changed to adjust the mechanical
advantage properties of the mechanism and that if the leg attached to the vertical
linkage the user moves is longer than the leg attached to the bar member there is
a greater mechanical advantage. Optionally, the door panels may be made of a honeycomb
material and are between1.27 cm and 1.905 cm (0.5" and 0.75") in thickness. Optionally,
the handles may not extend outwardly from the door so far as to be in the way, but
also may not easily catch on users' clothing or bags.
[0024] The blocking member may be moved by the four-bar linkage (as a result of movement
of the handle along the curved path) and may provide the blocking member with a quarter-circle
path of motion. This may cause the blocking member to move horizontally or outwardly
from its initial or first position approximately 2.54 cm (one inch) as well as vertically
up 2.54 cm (one inch). Optionally, the four-bar mechanism may consist of the blocking
member, three rectangular linkages or bar members that connect the blade to one corner
of the triangular members and the triangular members. The triangular members or brackets
may have a fixed point at the second corners, about which they pivot to produce the
desired motion. The triangular members may be connected at the third corner to each
other (via the vertical linkage) to maintain consistent motion. These three bracket
assemblies may make up the four-bar linkage to ensure that the motion of the blade
will be all translation and no rotation (two bracket assemblies can be used). At the
fixed corner of the triangular member, a biaxial mechanism may be used to force the
lock to either be in the locked or the unlocked position, with no stopping in an intermediate
position. As the door is locked, the spring may be compressed as the corner of the
triangle member presses into the spring. Once the handle has been moved past the halfway
point of the path and the spring is past the corner of the triangle member or detent
block, the spring may force the blocking member the rest of the way.
[0025] Optionally, the legs of the triangular brackets may have a ratio of 1:1 because that
ratio may provide the desired motion and a reasonable force. Optionally, each of the
triangle members may include a detent assembly associated therewith. However, optionally,
a single detent assembly may be included.
[0026] Optionally, the profile of the edge of the blocking member may be an ellipse to assist
with indexing the door panels in the center position and limit the friction forces
of the inserting of the blocking member into the receiver. Optionally, the components
of the lock assembly may mainly comprise HDPE to provide the lock with stiffness,
low weight and low friction forces. However, other plastics, metals and other materials
may be used for any of the components.
[0027] The handle may be made of aluminum, but can be made of other metal or plastic and
may be designed to help prevent users' clothing or bags from catching on the handle
if they decide to push the door in. Optionally, the door assembly may include four
handles: two on the inside and two on the outside. This may provide the option for
the user to push or pull on the doors when entering or exiting. The handle may be
fairly small and may allow for pulling with at least two fingers and at most four
fingers.
[0028] Any feature described herein in relation to one aspect, embodiment or example may
be combined with any other feature described herein in relation to any other aspect,
embodiment or example, as appropriate and applicable.

[0037] Referring now to the drawings, wherein the showings are for purposes of illustrating
the present invention of a lock assembly and not for purposes of limiting the same,
FIGS. 1-13 show a saloon-type door assembly that includes a hinge assembly and lock
assembly. The door assembly can be used in aircraft lavatories.
[0038] As shown in FIGS. 1-3, the saloon-type door assembly 10 generally includes a right
door assembly 12, a left door assembly 14, and a lock assembly 60. The saloon-type
door assembly 10 is positioned in a wall or door frame 100 that defines a door opening
102. The frame 100 includes a header 104. Each of the right door assembly 12 and left
door assembly 14 are movable between a closed position (see FIG. 1) and a front open
position (see FIG. 2) and a rear open position. FIG. 2 shows the right and left door
assemblies open to about 90° in the front open position. However, it will be appreciated
that the right and left door assemblies can open anywhere between 90° and 180°. In
a preferred ebodiment not forming part of the present invention, the right door assembly
12 includes a right hinge assembly 18 and a right door panel 20 and the left door
assembly 14 includes a left hinge assembly 22 and a left door panel 24.
[0039] FIGS. 4A-6B show different embodiments of the hinge assemblies which do not form
part of the present invention. For ease of description only the left hinge assembly
22 is shown and described. It will be appreciated that the description also applies
to the right hinge assembly 18 and associated components. As shown in FIGS. 4A-4B,
the left hinge assembly 22 includes a left frame adapter 26 and a left door adapter
28. The left frame adapter 26 includes a curved inner surface 30 that defines a first
apex 32. The curved inner surface 30 includes a front portion 30a and a rear portion
30b. The left door adapter 28 includes a curved outer surface 34 that defines a second
apex 36. The curved outer surface 34 includes a front portion 34a and a rear portion
34b. As shown in FIG. 4A, the curved inner surface 30 opposes the curved outer surface
34. It will be appreciated that the front and rear portions of the curved inner and
outer surfaces are defined by or divided by the first and second apexes 32 and 36
(see the dashed line in FIG. 4A).
[0040] As shown in FIGS. 4A-4B, the hinge assembly includes front and rear hinge strips.
Preferably, the left hinge assembly 22 (and left door assembly 14) includes at least
one front hinge strip 38 that is secured along at least a portion of a front hinge
strip path and at least one rear hinge strip 40 that is secured along at least a portion
of a rear hinge strip path. The front hinge strip path extends from the front portion
34a of the curved outer surface 34 of the left door adapter 28 to the rear portion
30b of the curved inner surface 30 of the left frame adapter 26. The rear hinge strip
path extends from the rear portion 34b of the curved outer surface 34 of the left
door adapter 28 to the front portion 30a of the curved inner surface 30 of the left
frame adapter 26. In a preferred embodiment, the left hinge assembly 22 includes a
plurality of alternating front and rear hinge strips 38 and 40 that extend vertically
thereon. The hinge strips can be separate pieces or they can form a hinge band 42
(where they are all connected together), as shown in FIGS. 3-3B. In a preferred embodiment,
the alternating front and rear hinge strips are connected along the portions that
cover the apexes of the curved inner and outer surfaces to form the hinge band 42.
In this embodiment, the connected portion of the hinge band 42 is referred to herein
as the apex portion 42a. FIG. 3A shows the hinge band 42 with a connected apex portion
42a. FIG. 3B shows the hinge band 42 in a stretched or laid out position. In other
words, it shows the front and rear hinge strips prior to being wrapped around the
frame and door adapters. FIG. 3C shows an alternate hinge band orientation where the
front and rear hinge strips only extend in one direction and either wrap around the
frame adapter or the door adapter.
[0041] In the embodiment shown in FIGS. 4A-4B, the left door adapter 28 includes a flat
surface 44 opposite the curved outer surface 34. In a preferred embodiment, the front
and rear hinge strips 38 and 40 are secured to this surface. As a result, the front
and rear hinge strip paths start from the flat surface 44. The left frame adapter
26 also preferably includes a flat surface 46 that can be a part of the hinge strip
path. In a preferred embodiment, flat surfaces 44 and 46 are generally parallel to
a line tangent to the associated apex 32 and 36 of the curved inner or outer surface
30 and 34. In a preferred embodiment, the front and rear hinge strips 38 and 40 are
adhered to the frame adapter 26 and door adapter 28 (or frame and door panel) along
surfaces other than the curved inner and outer surfaces 30 and 34 (e.g., flat surfaces
44 and 46 and/or the front and rear surfaces of the door panel or frame). In other
words, in this embodiment, the front and rear hinge strips are not secured to the
curved inner and outer surfaces 30 and 34. This allows the strips in the areas adjacent
to the curved inner and outer surfaces to move or stretch during opening and closing.
In another embodiment, the front and rear hinge strips are secured to the curved inner
and outer surfaces 30 and 34.
[0042] It will be appreciated that, generally, the left door adapter 28 is associated with
the left door panel 24. This is a broad way of saying the left door adapter 28 can
be a separate piece that is attached to the left door panel 24 (FIG. 4A) or the left
door adapter 28 is monolithically formed with or a part of left door panel 24 (FIG.
5A). Specifically, in FIGS. 4A-4B, the left door panel 24 includes an inner surface
24a to which the left door adapter 28 is attached. It will also be appreciated that,
generally, the left frame adapter 26 is associated with the frame 100 on the left
side of the wall where the door assembly 10 is mounted. This is a broad way of saying
the left frame adapter 26 can be a separate piece that is attached to the frame 100
(FIG. 4A) or the left door adapter 28 is monolithically formed with or a part of the
frame 100 (FIG. 5A). Specifically, in FIGS. 4A-4B, the frame 100 includes an inner
surface 100a to which the left frame adapter 26 is attached.
[0043] The left door adapter 28 can be secured to the left door panel 24 via threaded fasteners,
rivets, adhesive, glue, etc. Furthermore, the left door adapter 28 can be secured
directly to the portions of the front and rear hinge strips 38 and 40 that are interposed
between the left door adapter 28 and the left door panel 24. The left frame adapter
26 can be secured to the frame 100 via threaded fasteners, rivets, adhesive, glue,
etc. Furthermore, the left frame adapter 26 can be secured directly to the portions
of the front and rear hinge strips 38 and 40 that are interposed between the left
frame adapter 26 and the frame. FIG. 3 shows openings 48 in the various adapters for
securing the adapters to the frame or the door panels.
[0044] It will be appreciated that the left and right door panels 24 and 20 are both movable
between a front open position, a closed position and a rear open position and the
inner surface of the left door panel opposes the inner surface of the right door panel
when they are each in the closed position. The front and rear hinge strips 38 and
40 bias the left and right door panels to the closed position.
[0045] FIGS. 5A-5B show an embodiment which does not form part of the present invention,
where the front and rear hinge strips 38 and 40 do not extend to a flat surface on
the back of the left frame adapter 26 or left door adapter 28. This can be used in
an embodiment where the left frame adapter 26 and left door adapter 28 are monolithically
formed with the frame 100 and left door panel 24, respectively (i.e., where the inner
and outer curved surfaces are formed on the frame and the left door panel).
[0046] FIGS. 6A and 6B show an embodiment which does not form part of the present invention,
where the front and rear hinge strips 38 and 40 are a hybrid of the embodiments shown
in FIGS. 4A-5B. This can be used, for example, where the curved outer surface 34 is
formed directly on the left door panel 24 and the left frame adapter 26 is used to
attach to the frame 100.
[0047] As shown in FIGS. 2 and 3, in a preferred embodiment which does not form part of
the present invention, the right door panel 20 includes a first magnet member 50 disposed
adjacent a top edge thereof and the header 104 of the frame 100 includes a second
magnet member 52 disposed adjacent a bottom edge thereof. Furthermore, the left door
panel 24 includes a first magnet member 50 disposed adjacent a top edge thereof and
the header 104 of the frame includes a second magnet member 52 disposed adjacent a
bottom edge thereof. These magnet members 50 are used to help move or pull the left
and right door panels 20 and 24 to the closed position. The door assemblies can also
include opposing magnet members 50 and 52 in the door adapter 28 and the frame adapter
26 (see FIG. 3). These magnets also help pull the left and right door panels and/or
the left and right hinge assemblies back to the closed position.
[0048] FIGS. 7-13 show a preferred embodiment of the present invention of the lock assembly
60 for locking the left and right door panels 24 and 20 in the closed position. As
shown in FIGS. 7-10, generally, the lock assembly 60 includes a vertical linkage or
vertical bar 62, a blocking member 64, and one or more linkage assemblies 66 that
connect the vertical bar 62 to the blocking member 64. Preferably, the vertical bar
62 includes handles 68 extending outwardly therefrom.
[0049] As shown in FIGS. 2-3, the lock assembly 60 is positioned in the left and right door
panels 24 and 20. In a preferred embodiment, the lock assembly 60 also includes a
receiver member 70 that includes a pocket 72 defined therein. In use, the blocking
member 64 is received in the pocket 72 to lock the door assembly 10 or to prevent
the door panels from being opened. The receiver member 70 can simply be a pocket 72
cut or carved into the door panel or can be an insert (see FIGS. 11-13) that includes
the pocket 72 defined therein and that is secured in the door panel. In the embodiment
shown in FIGS. 2-3, the blocking member 64 and associated components are secured in
the right door panel 20 and the receiver member 70 is associated with the left door
panel 24. For example, the blocking member 64 and associated components can be positioned
in or housed in a space in the right door panel 20 the is defined between the front
and rear surfaces. However, this arrangement can be reversed.
[0050] In a preferred embodiment, each linkage assembly 66 includes inner and outer triangle
members 74a and 74b that form a triangle member assembly 74, a bar member 76 and a
detent assembly 78. In another embodiment, one of the inner or outer triangle members
can be omitted and only a single triangle member can be used in the linkage assembly
66. This arrangement is still referred to herein as a triangle member assembly 74.
The triangle member assembly 74 and bar member 76 cooperate to form a four bar linkage.
As shown in FIG. 7, various components of the linkage assembly 66 can be secured together
using threaded fasteners 80, brackets 82 and the like. Other mechanical fasteners,
such as rivets, welding, glue, etc. can also be used.
[0051] As shown in FIG. 8, the triangle member assembly 74 (of each linkage assembly 66)
includes first, second and third corners 75a, 75b and 75c. The first corner 75a is
pivotably or rotatably attached to a first end 76a of the bar member 76 and the third
corner 75c is pivotably or rotatably attached to the vertical bar 62. The second end
76b of the bar member 76 is pivotably or rotatably attached to the blocking member
64. As shown in FIG. 8, the triangle member assembly 74 also includes first, second
and third legs 75d, 75e and 75f. In a preferred embodiment, the first and second legs
75d and 75e are the same length, and the third leg 75f is longer than the first and
second legs 75d and 75e. In another embodiment, the first and second legs can be different
lengths. In another embodiment, the third length can be shorter than one or more of
the first and second legs.
[0052] As shown in FIGS. 2 and 8, the handle 68 extends outwardly through a curved slot
84 that is defined in the right door panel 20 (or left door panel if the arrangement
is reversed). The curved slot 84 allows the handle 68 to be moved along a curved path.
Because the handle 68 extends outwardly from the vertical bar 62, movement of the
handle 68 along the curved path causes the vertical bar 62 to move along a similar
curved path having the same curvature or shape. Furthermore, because the third corners
75c of the triangle member assemblies 74 are pivotably attached to the vertical bar
62, movement of the vertical bar 62 along the curved path causes movement of the third
corners 75c of the triangle member assemblies 74 along a similar curved path having
the same curvature or shape. As a result of this movement, the blocking member 64
moves horizontally (to the right in FIGS. 8-10) and away from the vertical bar 62
and handle 68.
[0053] With reference to FIGS. 8-10, the movement of the blocking member 64 is shown. FIG.
8 shows the blocking member 64 in the first position and the handle 68 in the starting
position (where the doors can be opened), FIG. 9 shows the blocking member 64 after
the handle 68 has been partially moved along the curved path, and FIG. 10 shows the
blocking member 64 in the second position and the handle 68 in the finish position
(where the doors cannot be opened). During movement of the handle 68 along the curved
path, as a result of the movement of the third corner 75c, the triangle member assembly
74 pivots about the second corner 75b and the first corner 75a moves upwardly and
to the right, which also moves the first end 76a of the bar member 76. As a result
of the length of the third leg 75f of the triangle member assembly 74, and the connection
of the second end 76b of the bar member 76 to the blocking member 64, the blocking
member 64 moves outwardly and to the right (as well as upwardly). In use, this movement
causes the blocking member 64 to be received in the pocket 72. See FIGS. 11-13, which
show the blocking member 64 moving into the pocket 72. Therefore, a first distance
is defined between the handle 68/vertical bar 62 and the blocking member 64 when the
blocking member is in the first position and a second distance is defined between
the handle 68/vertical bar 62 and the blocking member 64 when the blocking member
64 is in the second position and received in the pocket. It will be appreciated that
the second distance is greater than the first distance. It will also be appreciated
that as a result of both the vertical bar and handle having a horizontal component
of movement during movement of the blocking member (when locking the doors), the distance
the blocking member 64 moves relative to the insert member 70 is greater than the
movement of the blocking member 64 relative to the vertical bar 62 (the second distance).
[0054] It will be appreciated that a simpler version of the lock assembling 60 includes
only a single linkage assembly 66 with a single triangle member assembly 74. In this
embodiment, the vertical bar 62 can be omitted and the handle 68 can extend from the
third corner 75c of the triangle member assembly 74. As long as the handle 68 is associated
with the third corner 75c either directly (i.e., located on the corner) or indirectly
(i.e., located on the vertical bar 62 that is attached to the third corner) such that
it can move the third corner 75c along the curved path, the assembly will work properly.
In a preferred embodiment, the first leg 75d is generally vertically oriented in the
first or start position and the second leg 75e is generally horizontally oriented
in the first or start position.
[0055] The detent assembly 78 is provided to hold the blocking member 64 in the first or
second position. In a preferred embodiment, the detent assembly 78 includes a bracket
86, a spring 88 and a cap 90. The bracket 86 is mounted or otherwise secured to the
door panel and within a space or opening within the door panel. The spring 88 extends
downwardly from the bracket so that the cap 90 engages with and is pressed against
the second corner 75b of the triangle member assembly 74. In the start position (shown
in FIG. 8), the cap 90 presses against the second leg 75e of the triangle member assembly
74 and in the finish position (shown in FIG. 10) the cap 90 presses against the first
leg 75d. In a preferred embodiment, the triangle member assembly 74 second corner
75b includes a detent surface 92 that extends between the first leg 75d and the second
leg 75e and over the second corner 75b. As the triangle member assembly 74 pivots
from the start position to the finish position, the cap 90 rides or slides on the
detent surface 92. As shown in FIG. 7, in a preferred embodiment, the detent surface
92 is defined on an insert 94 that is sandwiched between the inner and outer triangle
members 74a and 74b. In another embodiment, the insert 94 can be secured to a single
triangle member.
[0056] FIGS. 11-13 show cross-sectional plan views of the blocking member 64, receiver member
70 and pocket 72 as the blocking member moves between the first position and second
position. It will be appreciated that the blocking member 64 can be any shape that
allows it to fit within the pocket and prevent the doors from being opened. In a preferred
embodiment, the profile or shape of the leading or distal surface 95 of the blocking
member 64 is a portion of an ellipse or defines an elliptical cross-section (when
viewed from above) to assist with indexing the left and right door panels 24 and 20
in the center position and limit the friction forces of the inserting of the blocking
member 64 into the receiver member 70 and pocket 72. The ellipse has a major axis
extending parallel to the direction of movement of the blocking member 64 and a minor
axis extending laterally thereto. In such an embodiment, preferably the pocket 72
includes the same elliptical shape for receiving the blocking member 64. Preferably,
the receiver member 70 includes inclined or curved edges 96 at the leading edge thereof
that helps guide the blocking member 64 into the pocket 72.
[0057] As shown in FIGS. 1-3, in a preferred embodiment which does not form part of the
present invention, the right and left door panels 20 and 24 include handles 110 thereon
for opening and closing the door panels. Preferably, the handle 110 includes rounded
edges and generally has a U-shape. When positioned on a door panel, the main body
portion 112 of the handle 110 defines a pocket 114 with the door panel and defines
an opening 116 that faces horizontally outwardly. In use, the user puts their hand
through the opening 116, into the pocket 114 and pulls or pushes to open the doors.
