Abstract
A folding table structure is provided which, when unfolded, provides a horizontal or inclined table top surface. The foldable table consists of a table top assembly, a one or two-piece support structure incorporating two rear legs, and two front leg assemblies. The table top assembly and the front leg assemblies are hinged to the support structure. Preferably the front leg assemblies are arranged so as avoid contact with the ground when folded and are retained in the folded position by the weight of the table top assembly. The table parts are assembled in such a way that the table may be folded or unfolded in one relatively fast, relatively low effort motion.
Description




This invention relates to foldable tables and more particularly to a folding table structure which, when unfolded, provides a horizontal or inclined table top surface.




BACKGROUND OF THE INVENTION




Tables that have foldable legs are well known. Typically they comprise four legs each of which is foldable in the sense that it is movable between a first stored position and a second extended position. Such prior known tables also have means for locking the legs in their extended position.




OBJECTS AND SUMMARY OF THE INVENTION




The primary object of this invention is to provide a table that can be easily folded and unfolded.




Another object is to provide a table which, when folded, has a very thin profile for ease of storage and shipping.




A further object is to provide a table support structure that is very simple and inexpensive to construct and can be adapted so that when it is unfolded, it provides a level or inclined table top.




Still another object is to provide a table support structure design that can be easily adapted for to provide a freestanding table unit or a table that is attached to a wall or other supporting structure.




Another important object is to provide a folding table which can be made lightweight and aesthetically pleasing using a variety of materials.




The foregoing objects are achieved by providing a table comprising a table top assembly, which may be of any shape or complexity dictated by its intended use, a one or two-piece support assembly for supporting the table on a floor or deck or attaching it to a vertical wall or other supporting structure, means for hinging together the table top assembly and the support assembly, two front leg assemblies pivotally attached to the support assembly whereby the two leg assemblies can be pivoted from a folded (i.e., stored) position to an extended position in which they support the table top assembly in a selected raised position, means for causing pivotal movement of the two leg assemblies from their folded to their extended positions, and means for causing pivotal movement of the two leg assemblies from their extended positions back to their folded positions. The front leg assemblies are arranged so as avoid contact with the ground when folded and are retained in the folded position by the weight of the table top assembly. The table parts are assembled in such a way that the table may be folded or unfolded in one relatively fast, relatively low effort motion. When the table top is lifted from vertical to horizontal position, the front leg assemblies automatically swing out until the leading edges of the front leg assemblies are approximately under the front edge of said tabletop assembly. The means for causing pivotal movement of the two leg assemblies from their extended positions back to their folded positions comprise cables that are attached to the two leg assemblies and extend through a hole (or other guide means) forming part of the support assembly. The ends of the cables are gathered together by a lightweight object that is bigger than the hole in the support assembly and serves as a handle. Other features are described or rendered obvious by the following detailed description and the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




Referring first to

FIGS. 1-14

, there is shown a folding table embodying the present invention which, when unfolded, is characterized by an inclined table top. The table shown in

FIGS. 1-14

comprises a table top assembly


2


, a support or rear assembly


4


, and two front leg assemblies


6


and


7


.




The table top assembly


2


comprises a rectangular frame


10


(

FIGS. 4

,


6


and


7


and a table top


12


that overlies and is affixed to frame


10


. The support assembly


4


is U-shaped, comprising a pair of parallel risers or rear legs


14


and


16


and a header


18


that extends between and is connected to the two risers. Preferably, a pair of angular brace members


22


and


24


extend between and are affixed to risers


14


and


16


and header


18


. Preferably the bottom ends of the risers are provided with feet in the form of rounded projections


26


. The header is hinged to the table top assembly by hinges


30


and


31


(

FIGS. 4

,


5


,


12


and


13


).




As seen best in

FIGS. 4-6

,


12


and


13


, the two leg assemblies


6


and


7


are mirror images of one another. Accordingly, the following description of front leg assembly


6


is to be understood as also describing the other leg assembly


7


. Essentially the leg assembly


6


comprises front and rear legs or risers


34


and


36


which are connected adjacent their bottom ends by a horizontal brace or stringer


38


. Front and rear leg members


34


and


36


differ in height as shown, and are connected at their top ends by a short horizontally-extending top member or header


40


and an inclined connecting strut


42


. The rear leg


36


of the leg assembly


6


is pivotally attached to riser


14


of support assembly


4


by a pair of spring hinges


44


as shown in FIG.


13


.

FIG. 14

illustrates a preferred form of spring hinge that may be used to attach front leg assemblies


6


and


7


to risers


14


and


16


respectively. It essentially consists of first and second hinge members


48


and


50


that are formed with gudgeons


52


and


54


respectively that are sized to receive a connecting pintle


56


. Additionally a coil spring


58


surrounds a portion of the pintle and has one end


59


A bearing against hinge member


48


and the other end


59


B bearing against hinge member


50


. As viewed in

FIG. 14

, the spring acts to urge the hinge member


48


to pivot clockwise relative to hinge member


50


.




Referring to

FIGS. 4

,


6


,


7


and


10


, attached to the table top frame


10


adjacent the front end of the table top are two similar spring clips


60


and


62


. As seen best in

FIGS. 7 and 10

, the spring clip


60


is L-shaped in cross-section, comprising a short portion


64


which is attached to the inner edge of the table top frame by suitable screws as shown at


66


, and a relative long portion


68


which extends at a right angle to portion


64


and parallel to the flat table top. One end of the longer portion


68


is formed with a curved flange extension


70


. Although not shown in detail in the drawings, spring clip


62


is identical to spring clip


60


except that it is formed with its curved flange extension shaped like flange extension


70


but facing in the opposite direction toward clip


60


.




The spring clips


60


and


62


are provided for engagement with identical pads


72


and


73


which are attached to the upper sides of top members


40


of the two front leg assemblies


6


and


7


. Referring now specifically to

FIGS. 6-8

, the top members


40


of the two leg assemblies are notched to accommodate the pads


72


and


73


. The pads are secured to the front leg assemblies by means of suitable fasteners


74


. As seen in

FIGS. 5-8

, the pads project beyond one end of the top surfaces of top members


40


so that they may be engaged by the curved flanges of clips


60


and


62


. The pads are preferably made of metal, but they also could be made of a plastic material provided that the plastic material has the appropriate flexibility and resilience to function in the manner hereinafter described. Referring now to

FIGS. 8-10

, each of the pads


72


and


73


comprises a thin resilient cantilever blade section


76


which is joined to two relatively thick and stiff block sections


78


and


80


which are connected to one end of blade section


76


by two connecting web sections


82


and


84


. The free end of blade section


76


is deformed to provide a depressed section or pocket


88


that has a narrow slot


90


extending back from its free edge. Slot


90


is sized to receive one of two flexible operating cables or cords


92


and


93


. The adjacent end of that cable is provided with an enlargement, preferably in the form of a round ball


94


as shown, which is sized larger than the width of slot


90


so as to prevent the cable from being pulled down through the slot.




Referring specifically to

FIGS. 8

,


10


and


11


, the top member


40


of each of the front leg assemblies has a notch or recess


96


on its outer side that intersects the top surface of that top member. Notch


96


connects with a hole


98


that passes completely through top member


40


. The cable


92


extends through notch


96


and out through hole


98


. The like cable


93


is connected in the same way to the other front leg assembly


7


. Both cables pass through an opening


102


in the header


18


of the rear support assembly


4


. The opposite end of each of the cables is connected to a circular handle or ring


104


which is used to facilitate the user pulling on both cables simultaneously when it is desired to unfold the table.




Referring again to

FIGS. 8-10

, each of the cantilever blade sections of the two pads


72


and


73


is provided on its upper side with a pair or projections


106


of suitable shape, preferably as flat ended cylinders as shown. Additionally, as shown in

FIGS. 4

,


7


and


10


, the underside of the table top is provide with a pair of blind holes


110


adjacent each of the spring clips


60


and


62


. The holes


110


are sized and located to receive the projections


106


of pads


72


and


73


when the two leg assemblies are in their extended position and the table top has its clips


60


and


62


engaged with pads


72


and


73


.





FIG. 1

shows the table in its folded or collapsed position. In this position, the two front leg assemblies


6


and


7


lie flat against support assembly


4


. When it is desired to erect the table, i.e., to unfold it, the user merely has to lift the table top which is lying flat against the front leg assemblies, pivoting it upwardly. As the table top pivots upwardly, the spring hinges


44


cause the front leg assemblies to pivot outwardly away from support assembly


4


, so as to extend them to the unfolded position shown in

FIGS. 5 and 6

. In this connection it is to be observed that

FIG. 3

illustrate the table top as it is in the process of being lifted and

FIG. 4

also shows the two front leg assemblies in the process of swinging outwardly to their extended positions. The front leg assemblies stop moving to their outward position when the handle


104


engages the rear side of the support assembly and/or the pads


72


and


73


engage the adjacent side sections of the frame


10


of the table top assembly. With the front leg assemblies in their extended positions, the flanges of the spring clips


60


and


62


engage the underside of the projecting end portions of the pads


72


and


73


, thereby locking the table in place vertically. Additionally the projections


106


extend into blind holes


110


, thereby locking the front leg assemblies against moving horizontally relative to the table top, i.e., locking those leg assemblies against pivoting relative to the back support assembly


4


. Since the top members


40


of the front leg assemblies are below the level of the header


18


of the rear support assembly, when the table is in its erected position, the table top assembly is disposed at an inclined angle to the floor or other support on which it is located, as shown in FIG.


12


. It is to be noted also that when the extended front leg assemblies are engaged with the floor or other support on which the table is resting, the legs of the front leg assembly and the rear support assembly extend at a slight angle from a true vertical position.




It is to be noted also that when the front leg assemblies are in their retracted or folded position (FIGS.


1


-


3


), their bottom ends are suspended off the ground by the rear support assembly. This is accomplished by appropriately sizing the vertical risers of the front leg assemblies and/or the risers of the rear support assembly, and/or by the addition of the feet


26


. Preferably but not necessarily, the feet are made so as to provide a non-slip surface to ease operation when the table top is erected.




When it is desired to fold the table back to the position shown in

FIGS. 1-3

, the user pulls on the handle of the table top assembly so as to cause the cables to pull down the cantilever blade sections


76


of pads


72


and


73


far enough to cause the projections


106


to clear the holes


110


and to cause the front leg assemblies to pivot back to their original folded (stored) position. As the front leg assemblies pivot back to their folded position, gravity returns the table top assembly to its lowered vertically-extending position. When the table top assembly is in its lowered vertically-extending position, its weight acts to prevent the spring hinges


44


from moving the front leg assemblies out of their folded position back to their extended position.





FIGS. 15-19

show a folding table embodying the present invention which when unfolded features a level table top rather than an inclined table top. This embodiment operates in the same manner as the table illustrated in

FIGS. 1-14

, except for differences rendered apparent from the drawings and the following description.




As seen in

FIG. 16

, the front leg assemblies


6


and


7


have longer front leg members


34


. Additionally, spacers


120


are attached to the underside of the table top assembly in position to engage the top members


40


of the front leg assemblies. These spacers have a thickness that is adequate to compensate for the thickness of the feet


26


so as to assure that the table top is level when engaged with the extended front leg assemblies. Also the spring clips


60


and


62


are mounted on the flat underside of frame


10


. A further differences that the rear support is a two-piece or dual structure, consisting of like support assemblies


121


and


122


. Each of these support assemblies comprises a vertical riser


123


, a top member


124


that is attached to and extends at a right angle from the riser, and an inclined brace member


126


which extends between the riser and the top member. The top members


124


are hinged to the table top frame by means of hinges


30


and


31


. The bottom ends of the risers are provided with feet


26


as in the previous embodiment. Since the rear support is a two-piece arrangement, a separate cable guide in the form of a yoke


132


is attached to the underside of the table top assembly frame


10


. Preferably, as seen in

FIG. 19

, the yoke


132


has two holes


134


,


135


extending through it. Cables


92


and


93


attached to the front leg assemblies pass through the holes


134


and


135


in yoke


132


and are attached to the ring-shaped handle


104


. The table shown in

FIGS. 16-19

opens and closes in the same manner as the embodiment previously described.





FIGS. 20-23

illustrate another form of the invention which also is characterized by a level table top when unfolded. In this case, the table top differs from the previous embodiments in that the rear support assembly


4


A is like one shown in

FIGS. 1-14

except for certain differences. For one thing, the table top assembly


2


A lacks the frame


10


of the previous embodiments and the spring clips


60


,


62


are attached directly to the table top


12


. Also, as seen best in

FIGS. 20 and 21

, the header


18


A of the rear support assembly has a forward extension


138


which overlaps the table top


12


when the table top assembly is in its lowered position. The table top assembly in this case is hinged at a level lower than in the previous embodiments of

FIGS. 1-19

. Secondly, a depending protrusion


142


is formed integral with header


18


A. Protrusion


142


has a hole through which the two cables


92


and


93


extend. Having the protrusion is done for the reason that it is necessary to have the holes through which the cables pass located so as to compensate for the lower position of the table top assembly


1


. This embodiment unfolds and folds like the previous embodiments.





FIGS. 24 and 25

illustrate another form of table similar to that shown in

FIGS. 20-23

except that the risers or legs of the rear support structure


4


B are provided with holes


146


to accommodate screws for mounting the tables to a wall or other supporting object, and also the feet


26


are omitted since they are unnecessary. The table is mounted on a wall or other supporting structure at a height convenient to the user which assures that the front leg assemblies are free to rotate as intended. Also in this case a yoke


132


is mounted substantially at the center of the table top


12


so as to assure that the handle will be in a position to be readily grasped by the user when the table is in its down position. For this purpose the cables are provided with a length sufficient to permit at least a portion of the handle


104


to extend below the table top when the latter is in its lowered position. This embodiment includes a second yoke or cable guide in the form of an integral projection


148


on the header


18


B of the rear support assembly. Yoke


148


has two holes


150


and


152


that intersect one another at a 90° angle. The cables


92


and


93


pass from the front leg assemblies


6


A and


7


A into the opposite ends of hole


152


and then out of the front end of hole


150


to the yoke


132


.




Still referring to

FIGS. 24 and 25

, to erect the table top assembly, the user pulls up on its front end, whereupon automatically the front leg assemblies will pivot into engagement with the clips


60


and


62


as previously described, thereby supporting the table top assembly in its raised position.




Obviously the invention is susceptible of still other modifications. For example, the shape and construction of the front leg assemblies can be modified. Thus, the front leg assemblies may be constructed so as to engage the ground or floor when the rear support is vertical. Similarly, the construction and shape of the table top assembly can be changed from what is illustrated. The number, size and location of the projections


106


may be varied. Also, the arrangement of projections


106


and blind holes


110


could be reversed. More specifically, the projections


106


could be eliminated from the cantilever blade sections of pads


72


and


73


and like projections affixed to the underside of the table top in place of the blind holes


110


, and blind holes or depressions like blind holes


110


could be formed in the cantilever blade sections to receive the projections on the underside of the table top. Still other modifications will be obvious to persons skilled in the art. The essential thing is that a table is provided which when unfolded provides a horizontal or inclined table top surface, with the table parts being assembled in such a way that the table may be folded or unfolded in one relatively fast, relatively low effort motion.
