Abstract
A table includes a round table top defining an unobstructed open slot that extends inwardly about halfway from a perimeter of the table top. The slot is shaped to receive a freestanding article of furniture slid horizontally into the slot, such as a screen, a partition panel, a leg of another table, or the like. The table top is pivoted to the base by links that are mechanically moveable over-center to a locking position when the table top is moved to a use position. A handle is formed as part of one of the links to assist with the over-center movement. The base is adapted to nest against similar bases for compact storage, and includes two feet with low-height flat ends that lie close to a floor surface so that they do not objectionably interfere with mating furniture nor with a person's feet when using the table.
Description
BACKGROUND
The present invention relates to nestable furniture, and more particularly relates to a table having a pivotally supported table top and novel base permitting nesting to adjacent tables when in use or in storage positions, and nesting to adjacent furniture in use positions for efficient use of space and optimal arrangement. However, it is noted that several of the present inventive concepts are not believed to be limited to only tables and table tops.
It is desirable to create a nestable table having a table top that is able to nest against and/or overlappingly move under a worksurface on existing furniture, even when the existing furniture has a leg or other interfering support structure located at an edge of its worksurface that would normally prevent moving the nestable table to a desired overlapped condition. Further, a table is desired that would nest against an end of a partition or screen, with half of the table being usable on each side of the partition or screen. Still further, it is desirable to provide a table top that can be easily unlatched and pivoted to a storage position for dense storage, and also easily and stably moved between use and storage positions without manipulating or fumbling with a cumbersome latch. Also, a stable table is also desired that does not have legs and feet that get in the way of a person's knees and feet while using the table.
Improvement is also desired for latch mechanisms for holding table tops in a use position. It is desirable to make the latch mechanisms less complex, yet to simultaneously improve their operation and function, to reduce their profile and the space they require, and to make them less expensive.
Accordingly, an apparatus solving the aforementioned problems and having the aforementioned advantages is desired.
SUMMARY OF THE PRESENT INVENTION
In one aspect of the present invention, a table includes a table top defining an unobstructed open slot that extends inwardly from a perimeter of the table top and that extends vertically through the table top, where the slot has a width and length shaped and adapted to receive a separate freestanding article of furniture slid horizontally into the slot through the perimeter. A base supports the table top, such as above a floor surface, and includes a leg attached to the table top. The base includes feet extending from a bottom of the leg to locations spaced away from under the slot so that an area below the slot from the table top to a floor surface is open and unobstructed.
In another aspect of the present invention, a table includes a table top, and a base including at least one leg pivotally supporting the table top for movement between a horizontal use position and a vertical storage position. A first link is pivoted to the table top for movement about a top pivot, and a second link is pivoted to the at least one leg for movement about a bottom pivot. The first and second links are movably attached to each other at a common joint for movement to a locking position where the common joint is moved over-center relative to a line connecting the top and bottom pivots, such that the table top is held in the horizontal use position, and for movement to a released position where the common joint is moved off-center relative to the line connecting the top and bottom pivots, such that the table top can be moved from the use position toward the storage position. A handle is attached to one of the links, with the handle being positioned for easy access under the table top when the table top is in the use position and being movable to push the first and second links from the over-center locking position to the off-center released position.
In another aspect of the present invention, a table includes a table top, and a base including a center leg with a fixed pivot pivotally supporting the table top for movement between a horizontal use position and a vertical storage position. A first link is pivoted to the table top for movement about a top pivot, and a second link is pivoted to the leg for movement about a bottom pivot. The first link slidably engages the second link at a common joint and, when the table top is in a horizontal use position, is movable between a locking position and a released position. The common joint includes a bearing with an end closest to the bottom pivot that moves over-center relative to the top and bottom pivots when the second link is moved toward the locking position.
In yet another aspect of the present invention, an article of furniture includes a furniture component, and a base supporting the furniture component. The base includes a post, and floor-engaging feet attached to the post that extend outwardly from the post. At least one of the feet includes a flat section with an elongated linear free end that extends horizontally and that has a transverse cross section that is elongated in a lateral direction and foreshortened in a vertical direction. By this arrangement, the free end is adapted to lie close to a floor surface and to not objectionably interfere with a position of a person's feet when using the furniture component.
In still another aspect of the present invention, a table supported on a floor surface includes a table top, and a base supporting the table top. The base includes a post and floor-engaging feet attached to the post. The feet include a low-profile vertically-thin foot that extends outwardly so that the first foot is adapted to provide a minimal bump on the floor surface, such that when the table is nested against a mating furniture unit, the vertically-thin foot does not objectionably engage and interfere with parts of the mating furniture.
These and other aspects, objects, and features of the present invention will be understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
A table
20
(
FIGS. 1-2
) includes a round table top
21
supported on a base
22
, with the table top
21
defining an open slot
23
that extends inwardly about half way from a perimeter of the table top
21
. The slot
23
is shaped to receive a freestanding article of furniture slid horizontally into the slot, such as a screen
24
, or an end of a partition panel
24
A, or a leg
25
or post of another table
26
(FIG.
11
), or a stand for a lamp, or the like. The table top
21
is pivoted to the base
22
by a pivot mechanism (
FIG. 2
) including slidably-interconnected pivot links
27
and
28
that, after the table top
21
is moved to a use position, are mechanically movable from an “off-center” unlocked position (
FIGS. 6 and 8
) to an over-center locked position (FIGS.
7
and
9
). A handle
29
is formed as part of the link
28
to assist with the over-center movement. The base
22
is adapted to nest against similar bases (
FIG. 10
) and non-similar bases (
FIG. 11
) for compact storage (
FIG. 10
) or overlapping use (FIG.
11
). In particular, the base
22
includes at least two feet
30
and
31
with flattened cross sections
32
that lie close to a floor surface so that they do not objectionably interfere with mating furniture nor with a person's feet when using the table
20
(see FIGS.
1
and
11
).
The illustrated table top
21
(
FIG. 2
) is made of standard table top materials, such as wood product covered with a scratch-resistant laminate top layer. The illustrated worksurface/table top
21
is about an inch thick or more, but it is noted that a variety of different materials and thicknesses can be used for the table top
21
. The pivot locations and internal friction level of the pivot mechanism can be adjusted to create an optimal balance as the table top is pivoted between use and storage positions. The illustrated table
20
has a center of mass located generally above the pivot axis
47
of the table top when the table top
21
is in a horizontal use position. By this arrangement, the table top
21
is relatively stable when in its use position, but the center of mass moves off-center of the pivot axis when the table top
21
is moved to a storage position, such that the table weight naturally biases the table top toward the storage position when in the storage position.
The slot
23
can be made as large and long as needed for its intended purpose. The illustrated slot
23
is about two inches wide and about twelve to sixteen inches long. It is large enough to receive a standard freestanding screen, such as screen
24
or a “fin” partition panel
24
A to a depth of about two-thirds of the radius of the table top
21
. It is contemplated that the slot could be made wide enough to engage a “spine” partition panel, such as are often about 4 inches thick and that carry electrical and other utilities, and could be made slightly deeper, if desired.
The illustrated base
22
(
FIG. 1
) includes a center post
35
, two flat feet
30
and
31
that extend radially from a bottom end of the post
35
, and two raised feet
36
and
37
that extend radially and horizontally from a location about 3 or 4 inches above the bottom end of the post
35
. Castors
38
and
39
are attached to the ends of feet
36
and
37
. Notably, the table top
21
is rotatable on the center post
35
, such that the feet
30
and
31
(or the castors
38
and
39
) can be located generally below and on either side of the slot
23
, making the area below the slot
23
open and unobstructed. The table
30
can be slid into position against the screen
24
, with feet
30
and
31
located on opposite sides of the screen
24
(FIG.
1
). Alternatively, by grasping an edge of the table opposite the castors
38
and
39
, the table
20
can be lifted and rolled into position against furniture such as a screen
24
, with the castors
38
and
39
rolling into positions adjacent the screen
24
and with an inner end of the slot
23
engaging the screen
24
.
The illustrated feet
30
,
31
,
36
, and
37
are arranged in an X-shaped pattern, with the feet
30
and
31
being arranged in a V-shaped pattern on one side and the feet
36
and
37
being arranged in a V-shaped pattern on the other side. However, it is contemplated that more or less of each type of feet can be used, and that they can be arranged in different patterns. The feet
30
and
31
are specially designed to have a transverse cross section with a low vertical profile. The illustrated feet
30
and
31
have a height of about ¼″ to ½″, with rounded edges, and a width of about 2 to 3 inches. However, the present inventive concepts are contemplated to include different profiles and shapes. An important and innovative aspect of the present feet
30
and
31
is that they provide enough strength to stably support the table
20
, yet they have a low enough profile such that they do not objectionably interfere with the feet of a person using the table. Also, by rotating the table top
21
so that the slot
23
is between the feet
30
and
31
, the feet
30
and
31
can be slipped under furniture having a short leg. For example, desks with drawers often have a short leg (similar to screen leg
24
B) under its drawers, providing a small space under the drawers above the floor surface that can receive the feet
30
and
31
.
The center post
35
(
FIG. 2
) is vertically extendable, and includes an internal gas spring with release button
40
at its top (FIG.
3
). An elongated handle
41
is extended through a bracket hole under the table top
21
, and includes an actuating finger
42
at its inner end shaped to engage and release the button
40
when the handle
41
is rotated, and includes a grip
43
at its outer end shaped to facilitate rotating the handle
41
. Preferably, the handle
41
is elongated in a direction parallel the pivot axis of the table top and extends to a location near an edge of the table top, so that the handle
41
is always easily accessible, even when in the storage position. By rotating the handle
41
, the release button
40
is depressed by the finger
42
and the gas spring is released to assist in lifting (or lowering) the table top
21
.
The pivot mechanism includes a base-attached stationary bracket
45
and a table-top-attached swing bracket
46
pivoted to the stationary bracket
45
by pivot pins
46
′ for movement about the pivot axis
47
. The swing bracket
46
includes a crescent shaped plate
48
attached to the table top
21
, first ear flanges
49
located at pivot axis
47
, and second ear flanges
50
. The stationary bracket
45
includes a center section
51
shaped to securely engage a top of the center post
35
. Arms
52
and
53
extend in opposite directions from the center section
51
, and include ear flanges
54
that align with ear flanges
49
. The pivot pins
46
′ extend through aligned holes in the ear flanges
49
and
54
for pivotally supporting the table top
21
for movement about axis
47
. Two parallel arms
55
and
56
extend forward of the center section
51
, and define front and rear spaces
57
and
58
therebetween. The rear space
58
receives the actuating finger
42
of handle
41
. Pivot flanges
59
extend from a front of the arms
55
and
56
. The link
27
includes two legs
60
that fit between and are pivoted to the pivot flanges
59
for movement about an axis
61
. The link
27
is a cast U-shaped component and includes a cylindrical body
62
that interconnects the legs
60
. The body
62
has a bore
63
transversely through it and an inner end
64
that are strategically located as discussed below.
The link
28
includes a J-shaped rod
65
and a handle
29
. The J-shaped rod
65
includes a first end
67
that is pivoted to the second ear flange
50
for movement about an axis
68
, and a rod section
69
that slidably/pivotally engages the bore
63
in the link
27
. As shown in
FIGS. 4-6
, the link
28
slidably engages the link
27
as the table top
21
is pivoted between a vertical storage position (
FIG. 4
) through intermediate positions (
FIG. 5
) to a horizontal use position (FIG.
6
).
In the non-locked horizontal use position (FIG.
6
), the pivot axis
68
is spaced above and slightly rearward of the pivot axis
61
, as represented by the angle of line
70
. The rear end
64
of the bore
63
(see line
71
) is located in an off-center non-locking position rearward of the line
70
connecting the axis
61
and
68
. This off-center position is illustrated by line
71
, which is drawn through the bore end
64
to the axis
68
. Accordingly, the direction of force on the rod section
69
by bore end
64
and bore
63
is such that the table top
21
can be lifted, and the rod section
69
will slide within the bore
63
to allow the table top
21
to be pivoted toward a storage position. (See
FIG. 5.
) However, when the handle
66
is pulled upwardly to a locking position, the bore end
64
moves over-center of the line
70
, as illustrated in
FIG. 7
, where the line
71
has moved across the line
70
. In the locking position, any upward lifting movement on the table top
21
causes the rod section
69
to bind up in the bore
63
, because the forces on the link
27
caused by the rod section
69
engaging link
28
cause a counter-clockwise torque on the link
27
that prevents the link
27
from rotating to a position where the link
28
can slide within the bore
64
. Notably, the position of the handle
66
is relatively close to an underside of the table top
21
when in the locking position, such that the handle
66
limits “over-rotation” or looseness of the table top
21
when the link
28
is in the locking position. Bumpers and stops can also be put on the brackets
45
and
46
and links
27
and
28
to limit over-rotation of the table top
21
, if desired. The close position of the handle to the table top
21
also prevents the handle
66
from interfering with knees of a person using the table top
21
. The handle
66
is spaced from the link
28
when in the locking position (FIG.
7
), such that it provides a substantial torque arm for moving the link
28
from the over center locking position back to the off-center unlocked position (FIG.
6
). Also, the handle
66
and rod section
69
are moved to positions close to the post
35
when the table top
21
is in the vertical storage position, such that the pivot mechanism provides a thin profile against the post
35
and the table top
21
for dense storage.
The present table
20
is particularly useful for dense storage (
FIG. 10
) against identical table
20
. Also, the table top
21
can be used on a table
90
having a more traditional base
91
with radial legs
92
, where the legs
30
and
31
of the table
20
fit under the spider legs
92
of the traditional base
91
.
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
