Description
BACKGROUND OF THE INVENTIONS
[0001] 1. Field of the Inventions
[0002] The present disclosure relates to a storage unit. More
specifically, it relates to a storage unit with an extension
mechanism that is configured to integrate a table, work surface
assembly, or other object with the storage unit and support the
object when it is deployed for use.
[0003] 2. Description of the Related Art
[0004] The prior art has attempted to integrate items with
conveniently-located storage units, for example, by integrating a
stowable tray with a bed headboard. In one example solution, a tray
is stowed within vertically extending front and back members inside
a headboard. A user deploys the tray by first rotating the tray
about a first pivot to extend the tray outwardly from between the
front and back members while maintaining its vertical orientation.
Then, the user rotates the tray about a second pivot to a
substantially horizontal orientation for its use as a tabletop. The
tray is only accessible on a side of the bed. Thus the example
solution does not permit a user reclining in the bed to use a
laptop computer and allows a very limited range of mobility for the
tray.
SUMMARY
[0005] In various embodiments disclosed herein, a storage unit is
disclosed into which an item can be integrated by an extendable and
adjustable mechanism that supports the item when the item is
deployed for use. Such a storage unit is multi-functional and space

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0037] Although certain preferred embodiments and examples are
disclosed below, it will be understood by those in the art that the
inventions extend beyond the specifically disclosed embodiments
and/or uses of the inventions and obvious modifications and
equivalents thereof. Thus, it is intended that the scope of the
inventions herein disclosed should not be limited by the particular
disclosed embodiments described below. The following descriptions
of various elements are applicable for the figure for which they
are provided, any other figures provided, and any embodiments not
shown.
[0038] FIG. 1 depicts a perspective view of two example storage
units. The left-side storage unit has a frame 10 and the right-side
storage unit has a frame 11. The storage units are integrated into
a bed headboard 20 and separated by a spacer portion 30. In one
embodiment, each storage unit comprises an arm assembly 40, 45
coupled with a respective storage unit frame 10, 11. The two arm
assemblies 40, 45 are shown in extended positions outside the
enclosed volume of their respective storage unit frames 10, 11. The
left-side arm assembly 40 comprises two extension arms 41, 42. A
work surface assembly 50 in a horizontally-deployed position is
coupled with the arm assembly 40. The left storage unit frame 10 is
shown covered by a moveable panel 60. The moveable panel 60 is
shown in FIG. 1 in a closed position. Other panels 70, 80 can be
provided proximate the moveable panel 60 to further enclose at
least a portion of the storage unit frame 10. A seating surface 100
is shown in phantom. The extension arms 41, 42 of the arm assembly
40 can be configured to position the work surface assembly 50
directly in front of a user seated on the seating surface 100 when
the user's back is resting on the moveable panel 60.
[0039] A wide variety of construction materials, for instance,
recycled material, metal (e.g., steel or aluminum), wood,
engineered material, melamine, or plastic or a combination of those
(or other) materials, are suitable for any of the components
described herein (e.g., storage unit frames, arm assemblies, work
surface assemblies, connectors, or panels).
[0040] As shown in FIG. 1, multiple storage units can, in certain
embodiments, be integrated into an article of furniture (here, a
bed headboard 20). Also, one or more storage units can be
integrated in other embodiments into a couch, a desk, a sectional,
cabinetry, or other furniture. In certain embodiments, only a
single storage unit is integrated into an article of furniture, for
example, a bed, chair, armoire, nightstand, endtable, or cabinet.
In embodiments in which an article of furniture comprises more than
one storage unit, one or more spacer portions such as the spacer
portion 30 shown in FIG. 1, can be provided between the storage
units to fill gaps and/or provide an aesthetically pleasing
appearance for the completed article. In certain embodiments, the
seating surface 100 can optionally be a mattress, a cushion, or a
flat surface. In certain embodiments, no seating surface is
provided.
[0041] The arm assembly 40 shown in FIG. 1 can be retracted inside
the enclosed volume of the storage unit frame 10 for storage and
deployed when ready for use. Also, the arm assembly 40 can provide
suitable support for any object(s) coupled with the arm assembly
40, for example, the work surface assembly 50. A storage unit can
comprise more than one arm assembly. For example, a first arm
assembly 40 supporting a work surface assembly 50 can be coupled
with the lower-left corner of the storage unit frame 10, and a
second arm assembly (not shown) supporting a task light (not shown)
can be coupled with the upper-right corner of the storage unit
frame 10.
[0042] FIG. 2 depicts a perspective view of example storage units
integrated into a bed headboard. The extension arms 41, 42 of the
arm assembly 40 can be configured to position the work surface
assembly 50 away from the seating surface 100 (shown in phantom) to
make it easier for a user to move from a seated position or a
reclining position on the seating surface 100 to a standing
position. A user can smoothly extend the arm assembly 40 and work
surface assembly 50 from the configuration shown in FIG. 1 to the
configuration shown in FIG. 2 by exerting a force on the work
surface assembly 50, for example, pushing. Likewise, the user can
smoothly extend the arm assembly 40 and work surface assembly from
the configuration shown in FIG. 2 to the configuration shown in
FIG. 1 by exerting a force (e.g., pushing or pulling) on the work
surface assembly 50.
[0043] FIG. 3A depicts a perspective view of an example storage
unit. A moveable panel 60 is coupled with the storage unit frame 10
by a mechanism (discussed below). The arrow 300 depicts movement of
the panel 60 toward an opened position, e.g., as shown in FIG.
3C.
[0044] Many configurations are suitable for storage unit frames.
The storage unit frame 10 shown in FIG. 3A has rectangular-shaped
surfaces. However, many regularly- and irregularly-shaped
three-dimensional bodies are also suitable shapes for storage units
frames. For example, a storage unit can be configured to serve as
the back support of a chair, and the storage unit frame can
comprise generally trapezoidal-shaped faces with rounded
corners.
[0045] Many configurations are also suitable for a moveable panel,
such as the moveable panel 60 shown in FIG. 3A, if it is present in
a particular embodiment. The moveable panel 60 can be configured to
move from a closed position to an open position in such a way that
allows the arm assembly 40 to be deployed from the enclosed volume
of the storage unit frame 10. In the embodiment shown in FIG. 3A,
the moveable panel 60 covers the front or forward portion of the
storage unit frame 10. In certain embodiments, the moveable panel
60 serves as a back rest for a user seated on a mattress or chair
cushion or other seating surface when the moveable panel 60 is
closed over the enclosed volume of the storage unit frame 10. The
moveable panel 60 need not be on the front of the storage unit in
all embodiments. It could, for example, be on a side portion of a
storage unit frame. The moveable panel 60 in the embodiment of FIG.
3A has a generally rectangular face. However, many regular and
irregular shapes are suitable for the moveable panel 60. The
moveable panel 60 need not cover an entire surface of the storage
unit frame 10. In certain embodiments, the moveable panel 60 covers
a face of the storage unit frame 10 where a face is at least a
portion of the surface of the storage unit frame 10. Certain
embodiments can comprise a plurality of moveable panels. In certain
embodiments, the moveable panel is not present.
[0046] The moveable panel can be configured for a number of
purposes. In the embodiment shown in FIG. 3A, the moveable panel 60
is configured to conceal the interior of the storage unit frame 10
when the moveable panel 60 is in a closed position. In other
embodiments, the panel 60 can be clear, leaving the inside of the
storage unit frame 10 visible therethrough. The moveable panel 10
may, in alternative embodiments, be configured for another purpose,
for example, to provide a work surface assembly such as a writing
surface or to provide a backrest as discussed above. The moveable
panel, in some embodiments, can be configured to provide a surface
for storing additional items. As an example, the moveable panel can
comprise hooks for hanging tools.
[0047] FIG. 3B depicts a perspective view of the example storage
unit of FIG. 3A. The arrow 304 depicts movement of the panel 60
toward an opened position. A user moves the moveable panel 60 from
the configuration shown in FIG. 3A to the configuration shown in
FIG. 3B by exerting a force on the panel 60, e.g., pulling
upwards.
[0048] The moveable panel 60 can be coupled with the storage unit
frame 10 by a suitable movement mechanism 500, for example, a pair
of four-bar linkage assemblies 500 comprising a four-bar linkage
510 and a strut 520. The four-bar linkage assembly 500 is discussed
in more detail in conjunction with FIG. 6 below. In certain
embodiments, the storage unit may comprise only one four-bar
linkage assembly 500. Other embodiments can comprise two or more
four-bar linkage assemblies 500. Moreover, a four-bar linkage
assembly 500 is not required. Alternative movement mechanisms 500
such as pivot connectors, ball-and-socket connectors, sliding track
connectors, and hinge connectors are also suitable for moveably
coupling the moveable panel 60 to the storage unit frame 10. Also,
the moveable panel 60 need not open in an upward direction.
Depending on the desired use of the storage unit, the moveable
panel 60 may open upward, downward, and/or from either side. In
certain embodiments, the moveable panel 60 may be configured to
open in more than one direction. Alternative movement mechanisms
500 can, in certain embodiments, be used in conjunction with one or
more struts 520 (discussed in more detail in conjunction with FIG.
6 below).
[0049] FIG. 3B shows the arm assembly 40 in a retracted position
inside the storage unit frame 10. A second extension arm 42 is
coupled with a first extension arm 41 by a swivel connector
(discussed below). When the arm assembly 40 is in a retracted
position, the second extension arm 42 is disposed over and
substantially parallel to ("stacked over") the first extension arm
41. However, in certain embodiments, an edge of the second
extension arm can deviate from the corresponding edge of the first
extension arm when the second extension arm is stacked over the
first arm. The substantially parallel configuration of the two
extension arms 41, 42 is also shown in FIG. 3C. The retracted
position shown in FIG. 3B advantageously allows an arm assembly 40
comprising two extension arms 41, 42 to be stowed in a storage unit
frame 10 having a narrow depth. However, alternative stowage
configurations in which the arm assembly 40 or assemblies can be
enclosed within a storage unit frame 10 are suitable. For example,
a telescoping extension assembly can comprise a series of nested or
interlocking hollow bars (not shown). In an example embodiment, a
coupler bar coupled with the storage unit frame has a circumference
or outer dimension. An intermediate bar placed inside the coupler
bar has a smaller circumference or outer dimension than the coupler
bar. A mounting bar placed inside the intermediate bar has a
smaller circumference or outer dimension than the intermediate bar.
A user extends the telescoping extension assembly by exerting a
force (e.g., pulling) on the mounting bar. The mounting bar extends
from inside the intermediate bar, and the intermediate bar extends
from inside the coupler bar. The bars can comprise a mechanism that
prevents a nested bar from falling outside of its surrounding bar.
For example, the intermediate bar and the mounting bar can comprise
a lip on their respective rearward end, and the coupler bar and the
intermediate bar can comprise a complementary catch on their
respective forward end. When the intermediate bar is extended from
the coupler bar a certain distance, the intermediate bar's lip
abuts the coupler bar's catch, and the coupler bar is prevented
from extending further. Likewise, when the mounting bar is extended
from the intermediate bar a certain distance, the mounting bar's
lip abuts the intermediate bar's catch, and the mounting bar is
prevented from extending further. An extension assembly comprising
a telescoping extension assembly can be stowed by exerting a force
on the mounting bar that causes the bars to slide inside of one
another and nest inside of each other. In another embodiment, an
extension assembly comprising an accordion-style arm (described
below) can be stowed by exerting a force on the arm, causing the
arm to retract on itself, as is known in the art.
[0050] A work surface assembly 50 is coupled with the second
extension arm 42 of the arm assembly 40. The work surface assembly
50 is shown in a vertical stored position behind the arm assembly
40. In alternative embodiments, the work surface assembly 50 is
stored in front of, underneath, or over the arm assembly 40.
[0051] FIG. 3C depicts a perspective view of the example storage
unit of FIG. 3A. A user moves the arm assembly 40 from the
retracted configuration shown in FIG. 3B to the first extended
configuration shown in FIG. 3C by swiveling, moving, rotating, or
pivoting the first extension arm 41 around a swivel connector. In
the embodiment of FIG. 3C, the swivel connector is a first pivot
connector 308. The work surface assembly 50 is shown in a
horizontally deployed position. A user moves the work surface
assembly 50 from the vertical stored position shown in FIG. 3B to
the horizontally deployed position of FIG. 3C by generally exerting
a force on the work surface assembly, e.g., pressing down on the
work surface assembly 50.
[0052] In certain embodiments, an aesthetic panel (not shown) is
coupled with the storage unit frame 10. The aesthetic panel can be,
for example, at the back face of the storage unit frame. When the
moveable panel is in an opened position, the aesthetic panel can
conceal a construction behind the storage unit. If the storage unit
is integrated into a headboard, for example, the aesthetic panel
can be upholstered or covered with veneer to complement the
aesthetic appearance of the moveable panel and/or other panels and
hide a portion of a construction (e.g., a wall) behind the storage
unit. In alternative embodiments, the aesthetic panel comprises a
sheet of paper, plastic, or fabric or any other suitable
material.
[0053] FIG. 3D depicts a movement of the arm assembly 40 from the
first extended configuration shown in FIG. 3C to the second
extended configuration. The second extension arm 42 is coupled with
the first extension arm 41 by a swivel connector. In the embodiment
of FIG. 3D, the swivel connector is a second pivot connector 312. A
user pivots the second extension arm 42 around the second pivot
connector 312 to move the work surface assembly 50 to the second
extended configuration.
[0054] FIG. 3E depicts a perspective view of the example storage
unit of FIG. 3A. A user moves the arm assembly 40 from second
extended configuration shown in FIG. 3D to the third extended
configuration shown in FIG. 3E by pivoting the second extension arm
42 around an axis of the second pivot connector 312.
[0055] Pivot connectors, e.g., the second pivot connector 312 shown
in FIG. 3C through FIG. 3E and the first pivot connector 308 shown
in FIG. 3B through 3E, are optional embodiments of swivel
connectors. Other kinds of swivel connectors that can move through
multiple degrees of freedom can be used in various embodiments. In
certain embodiments the swivel connectors comprise pivot
connectors, ball-and-socket connectors, hinge connectors, or
combinations thereof. In the embodiments shown in FIG. 3C through
FIG. 3E, the first 308 and second 312 pivot connectors comprise
pivot connectors in the same rotational plane. In other
embodiments, the swivel connector(s) can be replaced with another
suitable coupling mechanism that provides a suitable amount of
support to an item that a user chooses to couple with the extension
mechanism, that allows the extension mechanism to be retracted
inside the storage unit for storage, and that allows the extension
mechanism to be deployed from the storage unit when ready for use.
In certain embodiments, the suitable coupling mechanism can
comprise a stationary connector.
[0056] The two-extension-arm assembly described above is only one
optional configuration for the extension mechanism coupled with the
storage unit frame. In some embodiments, the extension mechanism
comprises arms.
[0057] In certain embodiments, the arm assembly comprises multiple
extension arms. In certain embodiments, the multiple-extension-arm
assembly can comprise more than two extension arms. For instance,
the arm assembly can comprise three or more arms serially connected
to each other by swivel connectors where one arm is connected to
the storage unit frame 10. However, the multiple extension arms
need not be connected to each other in this fashion. For example,
in certain embodiments the arm assembly comprises extension arms
wherein one end of each arm is slidingly engaged in a track or
tracks coupled with the frame. When the arm assembly is in a
retracted configuration, the arms lay flat inside the frame. As the
arm assembly is extended, the ends of the arms slide along their
track or tracks and the opposite ends of the arms become upright.
The extension arms shown in FIG. 3B through FIG. 3E are coupled
with each other near the end of the arms; however, the extension
arms can be coupled with each other at another point on either arm,
e.g., near the center or at a 3/4 position of either or both
arms.
[0058] In certain embodiments, the arm assembly comprises a single
extension arm. For example, the arm assembly can comprise an
accordion-style extension arm with diamond-shaped openings in the
middle of the arm and V-shaped openings along the edges of the arm.
The arm assembly can also comprise a telescoping extension arm. A
combination of expanding (e.g., accordion-style or telescoping)
arm(s) and/or solid bar(s) coupled by suitable connectors (as
described above) is also suitable. For instance, the arm assembly
can comprise two arms in the sliding-track configuration described
above with a third arm connected to those arms by a ball-and-socket
connector.
[0059] The configuration for the arm assembly 40 shown in FIGS. 3A
through 3F provides a wide range of mobility. If the storage unit
shown in FIG. 3F is integrated into an article of furniture
comprising a seating surface (e.g., a bed, chair, loveseat, or
couch), the arm assembly 40 can be configured so that a user seated
with his or her back resting on the moveable panel 60 has the work
surface assembly 50 directly in front of her. This advantageously
provides a work surface assembly 50 for a user who wishes to work
in a reclining position or in a seated position with his or her
back supported. The user can also adjust the position of the work
surface assembly 50, moving it nearer to or farther from the
moveable panel 60. The user can also move the work surface assembly
50 away from the article of furniture while maintaining the work
surface assembly 50 in a horizontally deployed position. This
advantageously allows a user to conveniently move to a standing
position while maintaining the placement of items on the work
surface assembly.
[0060] In the embodiments shown in FIG. 3A through 3F, the height
of the arm assembly 40 and the height of the work surface assembly
50 are not adjustable by a user. In certain alternative
embodiments, the height of the work surface assembly 50 and/or the
arm assembly 40 is adjustable, for example, by sliding the arm
assembly 40 and/or work surface assembly 50 along a rod and/or
track. For example, the first pivot connector 308 can be coupled
with a rod (not shown) that is coupled with the storage unit frame
10 and substantially parallel to the pivot axis of the first pivot
connector 308. The first pivot connector can be positioned within
an optional track (not shown) configured to prevent the first pivot
connector from rotating around the rod. A user can adjust the
height of the arm assembly 40 connector by sliding the first pivot
connector 308 along the rod and track. In certain embodiments, a
user can adjust the height of either the work surface assembly 50
or the arm assembly 40 or both by using a suitable connector, e.g.,
a ball-and-joint connector, that allows a user to raise and lower
the height of the arm assembly 40 or work surface assembly 50.
[0061] FIG. 3F depicts a perspective view of the storage unit of
FIG. 3A. In this example embodiment, the moveable panel 60 is
configured to be moved from an open position to a closed position
when the arm assembly is in a deployed position. The example arm
assembly 40 is coupled with the storage unit frame 10 in the
lower-left corner of that storage unit frame 10. A cut out in the
lower-left corner of the moveable panel 60 permits the moveable
panel 60 to close over the storage unit frame 10 when the arm
assembly 40 is in an extended position. Alternative configurations
can also permit the moveable panel 60 to close over the storage
unit frame 10 when the arm assembly 40 is extended. For example, in
certain embodiments, the moveable panel 60 is smaller than the
corresponding surface of the storage unit frame 10. If the moveable
panel does not completely cover the corresponding surface of the
storage unit frame when the moveable panel is in a closed position,
an additional panel or panels can be coupled with the storage unit
frame. The panels can completely conceal the interior of the
storage unit frame when the moveable panel is in a closed position.
In certain embodiments, the additional panels are stationary. In
certain embodiments, one or more of these additional panels are
moveable. For example, in the example configuration shown in FIG.
3F, an additional panel can be hingedly coupled with the storage
unit frame 10. In the example embodiment, the additional panel
covers the cutout in the lower-left corner when the arm assembly 40
is in a stored position. The hinge connection allows the additional
panel to move out of the way when the arm assembly 40 is in an
extended position.
[0062] The work surface assembly 50 shown in FIGS. 3B through 3F
has a rectangular face. However, many regular or irregular shapes
are suitable for the work surface assembly 50. In certain
embodiments, the work surface assembly comes pre-affixed with a
decorative covering and/or a protective cover (e.g., clear plastic
or glass). The work surface assembly can be customizable; for
example, it can be adapted to receive veneers which complement
other articles and/or decor in proximity with the work surface
assembly (e.g., other panels and/or spacer portions or other
furniture). In certain embodiments, the work surface assembly can
be detached from and recoupled with the arm assembly. This can, for
example, allow a user to more readily customize the work surface
assembly's appearance. For example, the work surface assembly 50
can be coupled with the arm assembly 40 using a small number of
standard head screws (e.g., four slotted-, Phillips-, or
hexagonal-socket screws). An example attachment is described below
in more detail in conjunction with FIGS. 11 and 12.
[0063] The work surface assembly (where present) can be configured
for a number of purposes. In certain embodiments, it is configured
for use as a planar task surface such as a typing surface, a
writing surface, or a reading surface. The work surface assembly,
in certain embodiments, comprises a mounting surface. For instance,
the work surface assembly can be configured for mounting a monitor,
television, or other electronic display.
[0064] The work surface assembly need not be present in all
embodiments. Further, other objects can be mounted to the arm
assembly, i.e., the work surface assembly need not be a planar
surface. In certain embodiments, for example, the item is a task
light, a magnifying glass, a hook or clip or other instrument for
coupling another item, or a mirror. Any object or combination of
objects that requires support when it is deployed for use can be
coupled with the arm assembly. In certain embodiments, the item to
be stored is configurable by the end-user. Thus, in certain
embodiments, there is no object connected to the arm assembly. The
arm assembly can comprise or be configured to receive a coupler
mechanism configured to couple an item of the user's choosing.
[0065] FIG. 4 depicts a top-down plan view of a storage unit
detailing the example arm assembly movements shown in FIG. 3D and
FIG. 3E. The arm assembly 40 position corresponding to the extended
position of FIG. 3D is shown in solid, and the position
corresponding to the extended position of FIG. 3E is shown in
phantom. In the position shown in phantom, the work surface
assembly 50 can be directly in front of a user (not shown)
reclining against a moveable panel (not shown) covering the forward
surface of the storage unit frame 10. As shown in the position in
solid, the user can move the work surface assembly 50 out of the
way (for example, for sleeping) while maintaining the work surface
assembly 50 in a horizontal position.
[0066] FIG. 5A, FIG. 5B, and FIG. 5C depict cross-sectional side
views of an example storage unit with a moveable panel 60 coupled
with the storage unit frame 10 in a closed position (FIG. 5A), an
intermediate position (FIG. 5B) between an open and closed
position, and an open position (FIG. 5C). In the embodiment of FIG.
5A, the moveable panel 60 is flush with and substantially
completely covers the storage unit frame 10. Alternative
embodiments of the moveable panel need not be flush with the
storage unit frame 10 and/or need not completely cover the storage
unit frame 10.
[0067] Certain embodiments comprise aesthetic considerations for
panels of the storage unit like the moveable panel 60 and other
panel 80 of FIG. 5A. In the embodiment of FIG. 5A, for example, the
moveable panel 60 is pre-affixed with a decorative covering 75,
e.g., paint, wood stain, veneer, or fabric. In certain embodiments,
the decorative covering 75 covers all surfaces of the moveable
panel 60. However, it need not cover all surfaces in all
embodiments. In certain embodiments, the moveable panel can be
customizable. The moveable panel may be adapted to receive veneers,
stains, paints, or fabrics of the user's choosing or any
pre-affixed veneers or fabrics, e.g., the decorative covering 75 of
FIG. 5A, may be removable and/or substitutable. For example, the
moveable panel can be bare, unfinished wood suitable for receiving
veneers, paints, stains, and/or fabrics which complement other
articles and/or decor near the moveable panel (e.g., other panels
of the headboard or other furniture in a room).
[0068] In embodiment of FIG. 5A, a panel moving mechanism couples
the moveable panel 60 with the storage unit frame 10. The example
mechanism comprises a four-bar linkage 510 including a ground link
530, a coupler link 540, and two grounded links (namely, a top
grounded link 550 and a bottom grounded link 560) located between
the ground link 530 and coupler link 540. Each of the links is
connected to two other links to form a closed quadrilateral loop.
Specifically, each grounded link 550, 560 is pivotally coupled with
the ground link 530 at one end and the coupler link 540 at the
other end. In certain embodiments, the ground link 530 can be
permanently coupled with of the storage unit frame 10 (e.g., welded
on or machined as part of the storage unit frame 10). In certain
embodiments, the ground link 530 is non-permanently coupled with
the storage unit frame 10 (e.g., screwed or snapped on). In the
example embodiment of FIG. 5, the ground link 530 couples with a
compliant extrusion 570 on the storage unit frame 10 by screws
580.
[0069] The coupler link 540 can be coupled with the moveable panel
60 by at least one fastener 590, e.g., by a small number of
standard head screws (e.g., two slotted-, Phillips-, or
hexagonal-socket screws). This can permit a user to quickly and
easily unscrew and decouple the moveable panel, cover it in fabric,
and recouple it by replacing the screws. Any suitable fastener,
however, can semi-permanently or permanently hold the moveable
panel 60 to the storage unit frame 10 (e.g., a bolt, clip, snap,
weld, or solder).
[0070] The coupler link 540 shown in FIGS. 5A through 5C moves
upward along an opening stroke 501 and consequently moves the
moveable panel 60 from a closed position (FIG. 5A) to an open
position (FIG. 5C). An intermediate position in this movement is
shown in FIG. 5B. In this example embodiment, the moveable panel 60
advantageously moves a relatively small distance from the storage
unit frame 10 during the opening stroke, i.e., the moveable panel
60 moves within a narrow envelope. In an example embodiment, a
panel 60 measuring around 21.5'' vertically moves at its greatest
extent around 6.5'' horizontally from the forward portion of the
storage unit frame 10. In certain embodiments, the ratio between
the panel's vertical height and the greatest extent of horizontal
movement is about 3:1. In other embodiments, the ratio between the
panel's vertical height and the greatest extent of horizontal
movement is greater than 3:1. In some embodiments, the horizontal
clearance can be considered the point of greatest separation of any
portion of the panel 60 from a front face of the storage unit frame
10. In one embodiment, the horizontal clearance of the panel 60 is
advantageously maintained less than the vertical height of the
panel 60. This arrangement enables a user to remain seated in front
of the storage unit frame 10 while operating the movement mechanism
500. Other embodiments require less horizontal clearance and for
such embodiments a hinge connection or other higher clearance
mechanism is suitable.
[0071] A narrow envelope between the moveable panel 60 and the
storage unit frame 10 in the opening stroke can be convenient for
users. For example, if the storage unit is integrated with a bed
headboard, and if the height of the moveable panel 60 is about
21.5'' inches as described above in connection with one embodiment,
a user only needs about 6'' of clearance from the storage unit
frame 10 in order to open the moveable panel 60. If the moveable
panel 60 were coupled with the storage unit frame 10 by hinge
connectors (not shown) at the top or side of the storage unit frame
10, then the moveable panel 60 would move through a much larger arc
in its opening stroke. In the example embodiment in which the
moveable panel 60 measures around 21.5'' vertically, a user
requires around 21.5'' of clearance from the storage unit frame 10
frame in order to open the moveable panel 60. As mentioned above,
such a hinge-connected embodiment is suitable for some
applications.
[0072] Alternative mechanisms can also allow the moveable panel 60
to remain in a narrow envelope from the storage unit frame 10
during the moveable panel's 60 opening stroke. For example, the
moveable panel 60 can be coupled with one or more sliding tracks on
the storage unit frame 10. For example, a first sliding track (not
shown) can be situated vertically along the right side of a forward
portion of the storage unit frame 10. An optional second sliding
track (not shown) can be situated vertically along the left side of
a forward portion of the storage unit frame 10. The first and
second sliding tracks can be substantially parallel to each other.
The moveable panel 60 can be coupled with a translation mechanism,
such as a plurality of rollers (not shown) on its left side and its
right side. The translation mechanism of the moveable panel 60 can
be inserted into the sliding tracks. A user exerts a force (e.g.,
pulls upwards) on the moveable panel 60. The force causes the
translation mechanism to slide along the sliding track and allows
the moveable panel 60 move upwards. In this example embodiment, the
moveable panel 60 remains substantially flush with forward portion
of the storage unit frame 10 during the opening stroke. In certain
embodiments, a sliding track comprises one or more struts, springs,
or other mechanical devices that assist the movement of the
moveable panel 60. Struts are discussed in more detail below. The
sliding track embodiments illustrate a very narrow movement
envelope for the panel 60 and correspond to a very small horizontal
clearance.
[0073] In the embodiments illustrated in FIG. 5A through 5C, the
coupler link 540 remains very nearly parallel to the ground link
530 along at least a portion of the opening stroke 501 (and also
along the closing stroke, not shown). A deviation from a parallel
line can be expected in some embodiments. In embodiments comprising
a four-bar linkage 510 in which the coupler link 540 remains
substantially parallel to the ground link 530 during the opening
stroke, the moveable panel 60 advantageously moves in a predictable
stroke so that a user can gauge and predict the moveable panel's 60
range of movement relative to the storage unit frame 10. This can
make the storage unit safer to use for first-time users or
infrequent users like hotel guests. However, the four-bar linkage
510 need not be configured to keep the coupler link 540 parallel to
the ground link 530 along the opening and/or closing stroke. Other
types of four-bar linkages as known in the art may also be
suitable. For example, the four-bar linkage 510 can be configured
to tilt the coupler link 540 and moveable panel 60 as they move
from a closed position to an open position.
[0074] The embodiment shown in FIG. 5A through 5C comprises a
suitable movement assisting mechanism, such as a pneumatic strut
with a piston 512 and cylinder 511. The piston 512 couples with the
storage unit frame 10 (e.g., screws 584 onto a complementary
extrusion 570 welded or machined onto the storage unit frame 10),
and the cylinder 511 couples with (e.g., by screws 588) the top
grounded link 550.
[0075] The strut 520 can be used to assist the movement of the
four-bar linkage 510 or to support the moveable panel 60 or both.
In certain embodiments, the strut 520 is configured to assist the
movement of the four-bar linkage 510. For example, a user can pull
up on the moveable panel 60, thereby engaging rotation in the
four-bar linkage 510 and engaging movement of the piston 512 in the
cylinder 511. If the user releases the moveable panel 60 at the
position of FIG. 4B (e.g., in a partially open position), the strut
520 can in certain embodiments continue to push the four-bar
linkage 510 and moveable panel 60 to an open position (FIG.
5C).
[0076] The strut 520 can also be configured to support the four-bar
linkage 510 and moveable panel 60 at one or more positions along
the opening stroke or closing stroke. A user can, for example,
grasp the moveable panel 60, move it upward to the position of FIG.
5B, and release his or her grasp of the moveable surface 60. The
strut 520 will maintain the position of the panel 60. Thus, if the
user releases the moveable panel 60 in the middle of the opening or
closing stroke, the moveable panel 60 will not suddenly swing shut.
In certain embodiments, the strut 520 supports the moveable surface
panel 60 at the top of the opening stroke. This advantageously
permits a user to extend and position an arm assembly and/or work
surface assembly (neither shown) stored inside the storage unit
frame 10 without having to simultaneously hold the moveable panel
60 in the open position. In certain embodiments, the strut 520
supports the moveable surface panel 60 during the opening stroke.
In certain embodiments, the strut 520 supports the moveable surface
panel 60 during the closing stroke.
[0077] Struts other than the type shown in FIGS. 5A-5C may be
suitable in various embodiments. In addition to or in place of a
pneumatic strut, fluid struts, mechanical struts and springs, or
other mechanical supports (e.g., levers) may also be suitable in
certain embodiments. Further, the strut may be configured in
alternate configurations. In certain embodiments, the piston 512
couples with the top grounded link 550 while the cylinder 511
couples with the bottom grounded link 540. In other embodiments,
the piston 512 couples with the bottom grounded link 540 while the
cylinder 511 couples with the top grounded link 550. The strut 520
can also in certain embodiments be a hinge coupler and couple the
storage unit frame 10 directly to the moveable panel 60. In certain
embodiments, the four-bar linkage assembly 500 (or other suitable
coupler between the panel 60 and the storage unit frame 10)
comprises a motor assembly. The motor assembly assists the movement
of the moveable panel and/or supports it in an open or partially
opened position.
[0078] A detailed perspective view of the four-bar linkage assembly
500 of FIGS. 5A through 5C is provided in FIGS. 6A and 6B. FIG. 6A
depicts the configuration of the four-bar linkage assembly 500
corresponding to the situation when the moveable panel (not shown)
is in a closed position (e.g., shown in FIG. 5A). FIG. 6B
corresponds to the situation when the moveable panel moves to an
opened position (e.g., shown in FIG. 5B). The configuration of the
top 550 and bottom 560 grounded links permit the coupler link 540
to remain substantially parallel to the ground link 530 during the
opening stroke.
[0079] FIG. 7 is a perspective exploded view of an example storage
unit. A pair of four-bar linkage assemblies 500 is coupled with the
storage unit frame 10. A mounting surface 610 is coupled with the
coupler links 540. A brace 620 is coupled with the top grounded
links 550, and a moveable panel 60 couples with the mounting
surface 610. In this way, the moveable panel 60 is coupled to the
storage unit frame 10.
[0080] The mounting surface 610 can facilitate the decoupling and
recoupling of the moveable panel 60. Other embodiments do not
include a mounting surface, and the moveable panel is coupled
directly to one or more four-bar linkages 510 or other suitable
connector(s). The brace 620 reinforces the four-bar linkages 510.
Other embodiments do not include a brace 620 if, for example,
reinforcement is not needed.
[0081] An arm assembly 40 and work surface assembly 50 are also
coupled to the storage unit frame 10. The arm assembly 40 comprises
a first extension arm 41 and a second extension arm 42 connected by
a second pivot connector 312. The first extension arm 41 couples
with a first pivot connector 308. The first pivot connector 308
comprises a bracket 710 with a top surface 720 and a bottom surface
730. The second extension arm 42 of the arm assembly 40 is inserted
between the top surface 720 and bottom surface 730. A pin 740 is
inserted through a hole 760 in the top surface 720, and the pin
passes through a complementary hole 750 in the first extension arm
41. The head of the pin 740 rests in a groove 770 in the bottom
surface 730. Certain embodiments do not include the bottom surface
730 of the bracket 710. The first pivot connector 308 couples with
the storage unit frame 10. In this way, the arm assembly 40 is
coupled with the storage unit frame 10. The work surface assembly
50 couples with the second extension arm 42 of the arm assembly
40.
[0082] Alternative configurations are suitable for the first pivot
connector 308. In the embodiment shown in FIG. 7, the first pivot
connector 308 is inserted such that the back of the bracket 710
faces the back face of the storage unit frame 10. Alternatively,
the back of the bracket 710 may face a side of the storage unit
frame 10, for example, the side 800 shown in FIG. 7. A removable
and repositionable bracket 710 is advantageous in certain
embodiments because it allows the arm assembly 40 to be located in
other portions (e.g., corners) of the storage unit frame 10 without
having to customize permanent coupling points on the storage unit
frame 10. For example, if two storage units were incorporated in a
headboard, a left-side swivel connector could be coupled with the
lower-left corner of the first storage unit frame and the first
storage unit placed on the left side of the headboard. A right-side
swivel connector could then be coupled with the lower-right corner
of an identical, rotated second storage unit frame and the second
storage unit placed on the right side of the headboard. This
configuration allows a manufacturer to machine large numbers of
identical storage units frames. This configuration also allows
users to adapt these storage unit frames for their own purposes and
attach one or more extension assemblies in nearly any place within
the storage unit frame in nearly any configuration. Nevertheless,
coupling points (e.g., resembling the bottom surface 730 and/or the
top surface 720 of the bracket 710) can be permanently coupled with
the storage unit frame 10 (e.g., welded or machined) in certain
embodiments.
[0083] FIG. 8 depicts a detailed perspective view of the first
pivot connector 308 discussed above with respect to FIG. 7. The
first pivot connector 308 comprises a bracket 710 with a top
surface 720 and a bottom surface 730. A retaining pin 740 is
inserted through a hole 760 in the top surface 720. A bottom
retaining ring 790 rests in a groove 770 in the bottom surface 730.
The head of the pin 740 rests in the bottom retaining ring 790. A
top retaining ring 780 is inserted into the hole 760 in the top
surface 720 and caps the other head of the pin 740. In certain
embodiments, the top retaining ring 780 and the bottom retaining
ring 790 facilitate a snug fit of the pin 740 within the hole 760
in the top surface 720 and groove 770 in the bottom surface 730
and/or smooth rotation of the pin 740. In certain embodiments,
first pivot connector 308 comprises a rotation limiter. For
example, the top retaining ring 780 and/or the bottom retaining
ring 790 can limit the rotation of the first extension arm (not
shown) when it is coupled with the first pivot connector 308. If an
object (e.g., a nightstand) is placed next to a storage unit and
the first pivot connector 308 did not include a rotation limiter,
the first extension arm could swivel farther than desired and
strike the nightstand or upset items placed on top of it. The
rotation limiter thus advantageously protects an object placed next
to a storage unit. In certain embodiments, the rotation limiter
also prevents the arm assembly from rotating out of easy reach of a
user. In certain embodiments, the rotation limiter prevents the
extension arms in the arm assembly from creating a pinch point. The
top retaining ring 780 and/or the bottom retaining ring 790 are not
present in certain embodiments.
[0084] FIG. 9 is a perspective view of an example arm assembly 40
in an extended position. The arm assembly comprises a first
extension arm 41 and a second extension arm 42 connected by a
second pivot connector 312. The first extension arm 41 has a hole
750 facilitating connection of the first extension arm 41 to a
first pivot connector (not shown). A work surface assembly 50 is
coupled with the second extension arm 42. In certain embodiments,
the work surface assembly 50 comprises a locking mechanism that
allows the tray to be maintained in one or more positions. For
example, the locking mechanism can maintain the work surface
assembly 50 in a horizontal position suitable, for example, for use
with a laptop computer and an angled position suitable, for
example, for reading. The work surface assembly 50 is shown in a
horizontally deployed position. An angled deployed position is
shown in phantom. An arrow 502 indicates that a user can move the
work surface assembly 50 from the horizontally deployed position to
an angled position by releasing a locking mechanism (if present),
exerting a force on the work surface assembly (e.g., pulling or
pushing), and re-locking the assembly in the angled position.
[0085] FIG. 10 depicts a top-down plan view of a storage unit
showing the rotation of a work surface assembly 50 coupled with an
arm assembly 40. A first horizontally deployed position of the work
surface assembly 50 is shown in solid lines. A position
corresponding to 90.degree. of rotation is shown in phantom lines.
Because the work surface assembly 50 is connected to the second
extension arm 42 by a swivel connector (not shown), this example
configuration permits a wide variety of rotational positions for
the work surface assembly 50. In certain embodiments, the swivel
connector (not shown) between the second extension arm 42 and the
work surface assembly 50 comprises a rotation limiting mechanism
that limit the rotation of the work surface assembly 50.
[0086] FIG. 11 is a bottom perspective view of an example arm
assembly 40 and work surface assembly 50. In the embodiment shown,
a hole 750 in the first extension arm 41 of the arm assembly 40
couples the first extension arm with a first pivot connector
coupled with the storage unit frame (not shown). A second pivot
connector 312 couples the first extension arm 41 to the second
extension arm 42 of the arm assembly 40.
[0087] The embodiment shown further comprises a rotation limiting
device 820 inserted into the second pivot connector 312 and secured
with a screw 830. The rotation limiting device 820 restricts the
rotation range of the second extension arm 42. The device 820 shown
includes a plug stop with a bar 804 that rests in a complementary
groove 850 within the second pivot connector 312. The second pivot
connector 312 comprises a C-shaped limiting ring 860. The second
pivot connector 312 rotates when the bar 804 is within the open
areas of the C-shape ring 860. The second pivot connector 312 stops
rotating when the bar 804 abuts the solid part of the C-shape ring
860. The rotation limiting device 820 may advantageously prevent
the arm assembly 40 from knocking over objects on, for example, a
bedside table if it is accidentally bumped when a user is arising
from bed.
[0088] A pivot connector 870 couples the work surface assembly 50
to the second extension arm 42. As described above with respect to
the first 308 and second pivot 312 connectors, the pivot connector
870 shown in FIG. 11 is an optional embodiment of a suitable swivel
connector. Other kinds of swivel connectors that can move through
multiple degrees of freedom can be used in various embodiments. In
certain embodiments the swivel connector comprises a pivot
connector, ball-and-socket connector, hinge connector, or
combinations thereof. In the embodiment shown in FIG. 11, the pivot
connector 870 and the second pivot connector 312 comprise pivot
connectors in the same rotational plane. In other embodiments, the
swivel connector can be replaced with another suitable coupling
mechanism that provides a suitable amount of support to an item
that a user chooses to couple with the extension mechanism. In
certain embodiments, the suitable coupling mechanism can comprise a
stationary connector.
[0089] In the embodiment shown, the pivot connector 870 is coupled
with a mounting assembly 874 (described in more detail below) which
is coupled with a tray 55. The mounting assembly 874 is not present
in certain embodiments, e.g., the pivot connector 870 can couple
the tray 55 directly to the arm assembly 40. A rotation limiting
device 878 similar to the one described for the second pivot
connector 312 above restricts the rotation range of the work
surface assembly 50. This may advantageously prevent the work
surface assembly from over-rotating if it is accidentally bumped
while a user has items like food, a beverage, or a laptop computer
resting on the work surface assembly 50. Rotation limiting devices
need not be used in conjunction with either the work surface
assembly 50 or the arm assembly 40. Moreover, alternative
mechanisms for limiting rotation can be used.
[0090] A mounting assembly 874 on the work surface assembly 50
comprises an attachment portion 886 and a limiter portion 890
connected by at least one hinge 894. The attachment portion 887 is
coupled with the second extension arm 42 by the pivot connector
870. When the tray 55 is in a vertical stored position (not shown),
the limiter portion 890 abuts the second extension arm 42, limiting
the rotation of the hinge(s) 894 and maintaining the tray 55 in an
approximately vertical position. Some deviation from a straight
line is to be expected. The limiter portion 890 is coupled with a
plate 895 mounted to the tray 55 by screws 898.
[0091] The work surface assembly 50 comprises a locking mechanism
882 for the mounting assembly 874. A pull-catch assembly 898 with a
handle 992 and catch (not shown) mounts over the plate 895. The
attachment portion 886 has a lip (not shown) which complements the
catch. When the tray 55 is pressed down into a horizontal position,
the attachment portion 886 abuts the plate 895. The lip snaps into
the catch, maintaining the tray 55 in a horizontally deployed
position. To move the tray 55 back to a vertical stored position, a
user pulls on the handle 992 to release the lip from the catch and
exerts a force (e.g., pushes) on the tray 55.
[0092] FIG. 12 is a bottom perspective exploded view of an example
work surface assembly. The mounting assembly 890 described in
conjunction with FIG. 11 is shown here in more detail. The limiter
portion 890 has a cover 996 and is coupled with the plate 895. The
plate 895 is mounted to the tray 55. A pull-catch assembly 898 with
a handle 992 and catch 1000 mounts over the plate 895. The
attachment portion 886 has a lip 1004 which complements the catch
1000. A rim 1008 surrounds the tray 55 in certain embodiments. The
rim 1008 can be aesthetic (e.g., a decorative ring of veneer or
plastic) and/or it can serve a functional purpose (e.g.,
maintaining items places on the top surface of the tray 55). The
rim is not present in certain embodiments.
[0093] FIGS. 13A and 13B are perspective views of an example
storage unit frame 10. A support portion 1012 is provided in
certain embodiments. The support portion 1012 can provide
additional support and/or coupling locations for a swivel connector
or other coupling assembly (not shown) that couples an extension
assembly with the storage unit frame. However, the support portion
is not present in certain embodiments. For example, a swivel
assembly can be mounted to a side or other portion of the storage
unit frame 10.
[0094] The storage unit frame 10 can be integrated into a storage
unit for use in a bed headboard. In the configuration shown in FIG.
13A, for example, a user can couple a swivel connector in the lower
left corner of the storage unit frame 10. If a user desires to
integrate a second storage unit into a bed headboard, for example,
a king-size bed headboard, then a user can provide a second storage
unit frame in the configuration of FIG. 13A, turn it upside down,
that is, rotate the storage unit frame 10 180.degree., and couple
another swivel connector in the lower right corner of the rotated
frame. The lower-right corner of the rotated frame 10 is equivalent
to the upper-left corner of the storage unit frame 10 in the
configuration of FIG. 13A. Certain embodiments allow a swivel
connector and/or extension assembly to be mounted to any portion of
the storage unit frame 10.
[0095] FIG. 14 is a perspective view of a structural portion of a
storage unit frame 10 illustrating a cleat bracket 1016 for
installing the storage unit frame 10 on an upright construction
(not shown). The cleat bracket 1016 catches in a complementary
groove 1020 near the top surface 80 of the storage unit frame 10.
In certain embodiments, a paper, fabric, or plastic guide in the
shape of storage unit frame can be provided to assist the mounting
process on the upright construction. For example, a paper guide can
be pre-printed with optimal fastener locations and/or the cleat
bracket location marked. A user can place the paper guide on a wall
to help envision how the storage unit will appear when mounted to
the wall and to assist in the mounting process. In certain
embodiments, the groove 1020 is located on other portions of the
storage unit frame 10. Alternative embodiments can use other
techniques (e.g., screws, nails, bolts, glue, hooks, etc.) for
mounting the storage unit frame 10 to an upright construction.
Further, the storage unit frame 10 can be mounted to other
constructions, e.g., a floor, a desk, a cabinet, a spacing or
support unit, or a chair. It can be supported from the top, bottom,
or any side. In certain embodiments, the storage unit frame 10 need
not be mounted.
[0096] FIG. 15 shows a side plan view of a storage unit frame
mounted on a cleat bracket 1016. The cleat bracket 1016 is screwed
1024 into an upright construction 1028 (e.g., a wall). The cleat
bracket 1016 catches in a complementary groove 1020 near the top
surface 80 of the storage unit frame.
[0097] A wide variety of variations are possible. Components may be
added, removed, or reordered. Different components may be
substituted out. The arrangement and configuration may be
different. Similarly, processing steps may be added or removed, or
reordered.
