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.
