DETAILED DESCRIPTION
[0019] Embodiments of the invention are discussed in detail below.
In describing embodiments, specific terminology is employed for the
sake of clarity. However, the invention is not intended to be
limited to the specific terminology so selected. A person skilled
in the relevant art will recognize that other equivalent parts can
be employed and other methods developed without departing from the
spirit and scope of the invention.
[0020] Embodiments of the present invention relate to a collapsible
table which may be quickly and easily assembled and disassembled,
for example, by a single user with no tools. The table may include
a latching device which uses a camming connection to engage and
disengage a retaining wedge. The retaining wedge may be movable by
the camming connection to a first position which allows the table
leg to be inserted or removed from the latching device and to a
second position which prevents the table leg from being moved,
removed, or inserted into the latching device. In this manner, the
table legs may be attached or detached from the table at any time
by a user.
[0021] Referring to FIGS. 1-3, a table 10 according to an
embodiment of the disclosure is shown. The table 10 may include a
table top 12 and one or more table legs 14. The one or more table
legs 14 may be coupled to the table top 12 with a latching device
16, such as a leg latching device, to be explained in more detail
to follow. The table 10 may include a recess 18. The recess 18 may
accommodate a person sitting or standing at the table 10 during
use. Although four table legs 14 are depicted, more or fewer legs
may be provided.
[0022] As may be appreciated from FIGS. 1-3, the table 10 may be
generally rectangular having a length 20 (FIG. 2) that is longer
than a width 22 (FIG. 3). Alternatively, the table may be other
shapes, for example, square, elongated, oval, elliptical, circular,
polygonal, etc. The table may be, for example, a desk, a conference
table, a standing table, a coffee table, a console table, an
outdoor table, or other type of table. The table top 12 may
comprise, for example, wood, plastic, metal, composite, laminate,
stone, marble, concrete, glass, or other materials.
[0023] Referring to FIG. 4, a bottom view of the table top 12 of
the table 10 (FIG. 1) is shown with the one or more table legs 14
(FIG. 1) removed. The table top 12 may have a lower surface 24 to
which the latching devices 16 are coupled. Each latching device 16
may include a bracket 30. The bracket 30 may be aligned
substantially with the corners of the table top 12. The number of
latching devices 16 may be selected to correspond to the number of
table legs 14 (FIG. 1) provided with the table 10 (FIG. 1). The
brackets 30 of latching devices 16 may have apertures 26 which
correspond to apertures (not depicted) on the lower surface 24 of
the table top 12. Fasteners 28 may be installed into the apertures
26 in brackets 30 and into the apertures on the lower surface 24.
The fasteners 28 may couple the brackets 30, and thus the latching
devices 16, to the lower surface 24 of the table top 12. Although
six apertures 26 and corresponding fasteners 28 are depicted for
each bracket 30, more or fewer apertures 26 and fasteners 28 may be
provided. The fasteners 28 may be, for example, screws, bolts,
pins, nails, etc. Alternatively, and without limitation, the
brackets 30 may be attached to the table top 12 by bonding or
welding, or may be co-formed with the table top 12. The table top
12 may include additional brackets 32 secured to the lower surface
24. The additional brackets 32 may provide a connection for a tray
or other component at a rear of the table. The tray may hold,
collect, or otherwise accommodate cords, cables, wires, power
cords, signal cables, etc.
[0024] Referring to FIG. 5, an exploded view of the latching device
16 is shown. As previously described, the latching device 16 may
include a bracket 30 having apertures 26. The bracket 30 may be
secured to the table top 12 (FIG. 4) with fasteners 28 inserted
into apertures 26. The latching device 16 may include a draw latch
34 which may be operable (e.g., pivotable) between a secured (FIG.
11) and unsecured (FIG. 10) position, as will be described in more
detail to follow. The bracket 30 may include a block 48 for
coupling the draw latch 34 to the bracket 30. A shaft 50 may be
inserted in an aperture in the block 48 and through corresponding
apertures in a cam follower 40 and a draw latch block 46. A
tensioning knob 54 may be provided on a threaded surface 56 at an
end of the shaft 50. The tensioning knob 54 may secure the shaft 50
to the draw latch 34. The tensioning knob 54 may also allow for
adjustment of the position of the draw latch 34, as will be
described in more detail to follow. Block 48 may be permanently
affixed to bracket 30. As may be appreciated, the shaft 50 passing
through the aperture in block 48 allows the draw latch 34 to move a
retaining wedge 52 relative to bracket 30.
[0025] With continued reference to FIG. 5, the cam follower 40 may
have a cam follower surface 42. The cam follower 40 may be pressed
between block 48 and draw latch block 46 to cause the cam follower
40 to be substantially stationary. As seen in FIG. 6, the cam
follower 40 may have one or more pins 40a received in corresponding
openings (unlabeled) of the block 48. The pins 40a may retain the
cam follower 40 in place against the block 48. The pins 40a may
retain the cam surface 42 in alignment with the cam surface 38. The
pints 40a may prevent rotation or skewing of the cam follower 40
with respect to the enlarged portion 36. Referring back to FIG. 5,
the cam follower 40 may be secured to the block 48 via shaft 50 and
tensioning knob 54. The cam follower surface 42 on the cam follower
40 may correspond to a cam surface 38 on the draw latch 34, for
example, on an enlarged portion 36 of the draw latch 34. During
operation, movement of the draw latch 34 may cause the cam surface
38 to rotate with respect to the cam follower surface 42 to provide
movement of the retaining wedge 52 between the secured and
unsecured positions.
[0026] The rotation of draw latch 34 may be provided by a pin 44
inserted through a transverse axis of the draw latch 34. The
enlarged portion 36 may have a curved outer surface which
corresponds to the cam surface 38. The cam surface 38 may be
eccentrically disposed with respect to the pin 44 in order to
create the cam profile of cam surface 38. The cam follower surface
42 may have a curvature that mates or substantially conforms with
the cam surface 38. As will be described in more detail, as the
draw latch 34 is moved to rotate the cam surface 38 within the cam
follower surface 42, the retaining wedge 52 may be moved between
secured (FIG. 11) and unsecured (FIG. 10) positions. Although
curved surfaces are depicted on the cam surface 38 and cam follower
surface 42, it will be appreciated that alternative surfaces may be
provided so long as one surface moves eccentrically with respect to
the other to create relative movement therebetween. Additionally,
alternative cam arrangements may be provided that create relative
movement, including rotational or linear movement, between the draw
latch 34 and the cam follower 40. The latching device 16, including
the draw latch 34, tensioning knob 54, latch block 46, pin 44, cam
follower 40, block 48, shaft 50, and/or retaining wedge 52 may
comprise, for example, plastic, metal, composite, other materials,
or any combination thereof. The components of the latching device
16 may be of the same material or different material.
[0027] As may be appreciated from FIG. 6, the bracket 30 of
latching device 16 may be substantially L-shaped. As such, the
bracket 30 may have a first bracket portion 30a and a second
bracket portion 30b joined by a corner bracket portion 30c. The
first bracket portion 30a and the second bracket portion 30b may be
connected by a corner 66. The first bracket portion 30a and second
bracket portion 30b may be perpendicular or substantially
perpendicular with respect to each other, although other angular
relationships are contemplated. Although a substantially L-shaped
bracket is depicted, alternative shapes of bracket 30 are
contemplated so long as the bracket 30 may accommodate the
remaining components of the latching device 16, such as retaining
wedge 52, shaft 50, draw latch 34, and associated components. The
bracket 30 may comprise, for example, plastic, metal, composite,
other materials, or any combination thereof.
[0028] The corner bracket portion 30c may be substantially flat and
may join the first bracket portion 30a to the second bracket
portion 30b. The corner bracket portion 30c may define a corner
recess for receipt of the table leg 14. The corner bracket portion
30c and associated corner recess may also accommodate the retaining
wedge 52. When assembled, a top surface of the retaining wedge 52
may be substantially aligned and co-planar with a top surface of
the first and second bracket portions 30a and 30b. A bottom surface
of the retaining wedge 52 may by parallel and offset from a top
surface of the corner bracket portion 30c. Thus, as may be
appreciated, the retaining wedge 52 may nest within the corner
recess defined by corner bracket portion 30c of the bracket 30. The
bracket 30 may include a first surface 58 on an end of the first
bracket portion 30a and a second surface 60 on the second bracket
portion 30b. The retaining wedge 52 may include a first retaining
surface 62 and a second retaining surface 64 aligned with the
surfaces 58 and 60, respectively. The first surface 58 may be
substantially parallel to and aligned with the first retaining
surface 62. The second surface 60 may be substantially parallel to
and aligned with the second retaining surface 64. During operation
of the latching device 16, the retaining wedge 52 may be moved
between a first position where the first retaining surface 62 and
second retaining surface 64 are offset a first distance from the
first surface 58 and second surface 60, respectively, and a second
position where the first and second retaining surfaces 62, 64 are
offset from the first and second surfaces 58, 60, respectively, at
second distance. The first distance may be smaller than the second
distance. At the first distance, a component, such as a table leg,
may be pressed or sandwiched between the respective surfaces of the
retaining wedge 52 and bracket 30 such that movement is prevented.
At the second distance, the component may be released such that the
component is moveable (e.g., removable) with respect to the
retaining wedge 52 and bracket 30. The movement between these
positions may be provided by moving the draw latch 34 between a
first position and a second position, as will be explained in more
detail.
[0029] Referring now to FIG. 7, a perspective view of a table leg
14 is shown. The table leg 14 may have a proximal end 68 and a
distal end 70. The proximal end 68 may engage the latching device
16 (FIG. 6). For example, at least the proximal end 68 of the table
leg 14 may define a hollow interior portion that can receive the
retaining wedge 52. The proximal end 68 may additionally include a
slot 72 provided at a corner of a first leg surface 74 and a second
leg surface 76. The slot 72 may pass into hollow interior portion
of the table leg 14 to allow the shaft (FIG. 6) to extend therein.
The distal end 70 of table leg 14 may include foot 78 for resting
on a floor or other surface. The foot 78 may be adjustable (e.g.,
using a threaded connection) and allow for height adjustment of
each individual table leg 14. The foot 78 may allow for adjustment
of each individual table leg 14 to level the table top 12 (FIG. 1).
Although a substantially square or rectangular table leg 14 is
depicted, other shapes of table leg 14 are contemplated. The table
legs 14 may comprise any material capable of supporting table top
12, such as wood, plastic, metal, composite, etc., or any
combination thereof.
[0030] Referring now to FIGS. 8-11, assembly of the table 10 (FIG.
1) will be described. The table 10 may be provided to a user with
the latching devices 16 attached to the lower surface 24 of the
table top 12. The one or more table legs 14 may be provided
detached from the table top 12. In this manner, the table 10 may be
permitted to be packaged, shipped, delivered, and/or stored in a
compact manner with the table legs 14 in a detached position. When
the table 10 is desired to be used, the table legs 14 may be
coupled to the table top 12 using one or more latching devices 16.
Although only one latching device 16 and one table leg 14 are
depicted in FIGS. 8-11, it will be appreciated that a latching
device 16 and corresponding table leg 14 may be provided in each
corner of the table top 12.
[0031] To couple the table legs 14 to the table 10, a top surface
(not depicted) of the table top 12 may be placed on a flat surface
with the latching devices 16 and lower surface 24 facing upward. In
the first step of FIG. 8, the draw latch 34 may be in a generally
horizontal position resting on the lower surface 24. Although, the
draw latch 34 may be provided in the generally vertical position
(FIG. 9) at this stage. The proximal end 68 of the table leg 14 may
be aligned with the corner notch defined by the corner bracket
portion 30c (FIG. 6) such that the slot 72 faces the corner 66 of
the bracket 30. In this position, the surfaces 60, 64, and 74 of
the bracket 30, retaining wedge 52, and table leg 14, respectively,
are generally parallel to one another. The surface 74 of the table
leg 14 may be located substantially between the surfaces 60 and 64
of the bracket 30 and retaining wedge 52, respectively. Similarly,
the surfaces 58, 62, and 76 of the bracket 30, retaining wedge 52,
and table leg 14, respectively, are generally parallel to one
another. The surface 76 of the table leg 14 may be located
substantially between the surfaces 58 and 62 of the bracket 30 and
retaining wedge 52, respectively.
[0032] Referring to FIG. 9, the draw latch 34 is shown in the
unsecured position which may correspond to the vertical position.
To move from the secured, horizontal position of FIG. 8 to the
unsecured, vertical position of FIG. 9, the user may rotate the
draw latch 34 to cause the cam surface 38 to rotate relative to the
cam follower surface 42 of the cam follower 40. In the unsecured
position, the retaining wedge 52 is offset or spaced from the
bracket 30 such that a gap is provided between the retaining
surfaces 62 and 64 of the retaining wedge and the corresponding
surfaces 58 and 60 of the bracket 30, respectively. The gap is
large enough to allow insertion of the table leg 14 into the corner
notch. After aligning the surfaces as previously described with
respect to FIG. 8, the table leg 14 may be lowered into the gap
such that an end surface (not depicted) of the proximal end 68
rests on or is located near the upper surface of the corner bracket
portion 30c (FIG. 6). Alternatively, the end surface (not depicted)
of the proximal end 68 may rest directly on the surface 24 of the
table top 12. The slot 72 in leg 14 may be aligned with the shaft
50. When the table leg 14 is lowered, the slot 72 may extend around
the shaft 50 to allow the end surface of the table leg 14 to be
near or touching the corner bracket portion 30c. In this manner,
the shaft 50 does not interfere with the placement of the table leg
14 in the corner notch in bracket 30. The table leg 14, or at least
the proximal end 68 of the table leg 14, may be hollow to
accommodate the retaining wedge 52 during coupling of the table leg
14 to the table top 12.
[0033] With reference to FIG. 10, the table leg 14 may be fully
inserted into the gap between retaining wedge 52 (FIG. 9) and
bracket 30 until the table leg 14 is in a substantially vertical
position that is substantially perpendicular to the table top 12.
With the draw latch 34 in the substantially vertical position, the
retaining wedge 52 is still spaced away from the bracket 30 such
that the gap between the retaining wedge 52 and bracket 30 is large
enough to allow movement of the table leg 14 back and forth and
into and out of the corner bracket portion 30c. Thus, although
properly aligned in FIG. 10, the table leg 14 may still be moved
around in the gap between the retaining wedge 52 (FIG. 6) and
bracket 30. In the position of FIG. 10, the table leg 14 is not
secured to the bracket 30.
[0034] To secure the table leg 14, the user may move the draw latch
34 from the substantially vertical position of FIG. 10 to the
substantially horizontal position of FIG. 11. As may be appreciated
from FIG. 11, during movement of the draw latch 34, the cam surface
38 moves with respect to the cam follower 42 of the cam follower
40. Due to the eccentric nature of the cam surface with respect to
the shaft 50, the movement of the draw latch 34 causes lateral
movement of the shaft 50 and retaining wedge 52 connected thereto.
The movement of the draw latch 34 pulls the shaft 50 and thus the
retaining wedge 52 (FIG. 6) inward toward the corner 66 of the
bracket 30. With the retaining wedge 52 drawn inward, the gap
between the retaining wedge 52 and the bracket 30 becomes smaller
(the "first distance"). In the secured position of FIG. 11, the
surfaces 74 and 76 of the table leg 14 are gripped or secured
between the retaining surfaces 62, 64 of the retaining wedge 52,
and the corresponding surfaces 58 and 60 of the bracket 30 (FIG.
6). In this position, the table leg 14 is prevented from moving in
the gap between the retaining wedge 52 and the bracket 30. The
table leg 14 is now secured to the bracket 30 and thus to the table
top 12.
[0035] The force applied to the table leg 14 by the retaining wedge
52 may be adjusted by turning the tensioning knob 54, which adjusts
the distance between the draw latch 34 and the retaining wedge 52.
Before the draw latch 34 has been moved to the secured position of
FIG. 11, the tensioning knob 54 may be turned to adjust the degree
to which the retaining wedge presses the surfaces of the table leg
14 against the bracket 30. The tensioning knob 54 may draw the
shaft 50 and thus the retaining wedge 52 closer to the corner 66 by
engaging the threaded surface 56 (FIG. 5). Once the table leg 14 is
secured in place in the bracket 30, the steps may be performed on
the remaining table legs 14 until all table legs 14 are properly
secured to table top 12. After all the table legs 14 are secured to
the table top 12, the table 10 may be rotated such that the feet 78
(FIG. 7) of the table legs 14 are located on the floor or other
surface on which the table 10 is placed. The feet 78 may then be
individually adjusted to provide a level table top 12.
[0036] To disassemble the table 10 for storage, transportation, or
other reasons, the table 10 may be rotated such that the top
surface of the table top 12 is placed on the floor or other flat
surface. The table legs 14 may then be removed from the table top
12. The process to remove the table legs 14 may be substantially
reversed from the process described in FIGS. 8-11. In order to
remove the table legs 14, the draw latch 34 may be moved from the
secured, horizontal position of FIG. 11 to the unsecured, vertical
position of FIG. 12. When the draw latch 34 is moved to the
vertical position, the retaining wedge 52 is moved away from the
corner 66. The gap provided between the retaining wedge 52 and the
bracket 30 becomes larger (the "second distance") allowing for
movement or removal of the table leg 14. In this position, the
table leg 14 may be moved upward to be removed from the corner
bracket portion 30c (FIG. 5) between the surfaces 58 and 60. This
process may be repeated with the remaining table legs 14 until all
of the table legs 14 have been removed from the table top 12. The
table 10 may now be moved or stored as desired. It will be
appreciated from the foregoing that the table may be assembled and
disassembled any number of times in any number of locations, as
desired by the user.
