Application November 6, 1950, Serial No. 194,224
This invention relates to foldable table and seat assemblies and more particularly to one in which the seats and their supports are so interconnected as to be compactly folded into a pair of hingedly interconnected receptacles which, when opened, constitute the table top, and which, when closed, constitute an enclosure for the seats and their supports.
` ln the table and seat assembly of the present invention the seat members are rigidly supported by foldable legs and in turn rigidly support the substantially rectangular table top at the four corners thereof. This support is afforded by a single rigid link arranged at each corner of the table top, the opposite ends of each link being pivotally connected to a corner and one end of a seat member, respectively. As the table top of the present invention is supported at the four corners thereof and not merely at the opposite sides intermediate the corners, the same is far more rigid in use and will take substantially heavier loads than the tables of prior assemblies.
The seat members and the links are held against relative movement once the said members are moved with the links to position at opposite sides 0f the table to thus provide a very rigid table and seat arrangement. To afford adequate support for the opposite ends of the table top formed by the hingedly interconnected receptacles, a pair of auxiliary legs may be pivotally mounted to at least one receptacle, which legs when swung downwardly will firmly support the opposite ends of the table top.
The link arrangement interconnecting the table top and seat members of the present invention permit the table and seat members to fold into a very compact carrying case. As the links fold into the receptacles to positions intermediate the ends of the seat members and the end walls of the receptacles, the supporting surfaces of the seat members, when the latter are moved with the links into the receptacles, are in facewise engagement with the under-surface of the table top formed by the two receptacles. In this folded position the partially collapsed or folded assembly forms a relatively large table supported at a level substantially that of the seat members. The table in this use of the assembly is directly supported by the seat members and their supporting legs and forms a table of a height substantially that of a conventional coffee table. The table furthermore, when so supported, is well adapted to be used at the beach or other recreational area where the users of the table prefer to sit or recline on the ground adjacent the table.
A further feature of the present invention re- 2 sides in the fact that the hinge means interconnecting the two receptacles are such that by slight manipulation the two receptacles forming the table top may be separated. It is thus possible with the assembly of the present invention to form two smaller tables of a height substan-l tially that of a conventional coffee table. The two smaller tables formed when the receptacles are disengaged are very rigid for the under surface of each receptacle is directly engaged and supported by the upper planar surface of the attached seat member.
Thus with the table and seat assembly of the present invention the table and seat members may be completely unfolded to provide a table having arranged along opposite sides thereof seat members which through the four links rigidly support the table above and between the seats. With the table and seat members so arranged, seating accommodations are provided such as are had with a conventional picnic table.
As the receptacles may be separated, an article of furniture in the nature of a writing desk may be had when desired merely by detaching the receptacle to which the auxiliary legs are secured from the other receptacle, after the seat member thereof and auxiliary legs are moved into their supporting position. The remaining receptacle, if desired, can be used as a small table in the nature of a coffee table as above described.
When the table is to be folded for transportation and storage, the legs of the seat members, after the seat members have been swung into their storage position within the receptacles, are merely folded against the undersurface of the seat members and the two receptacles moved together to form a carrying case. A latch or similar element holds the two receptacles together and the case so formed is carried by a handle fixed to one side wall of a receptacle.
Other features and advantages of the present invention will be hereinafter apparent from the following detailed description thereof, particularly when taken in connection with the accompanying drawing, in which:
Figure 1 is a perspective View showing the table and seat members in their fully extended position;
Figure 2 is a perspective view showing the table in its partially open position in which the table top is directly supported by the seat members;

The receptacles IQ are interconnected by a plurality of hinge members lll, as best seen in Figure 5, to permit the two receptacles to be moved orswung together to form the carrying case shown in Fig; ure 3. The hinge elements ifi also permitfth; two receptacles to be swung away from eachother to bring the outer planar surfaces of the transverse walls i3 into coplanarity to term a continuous surface or table top, as clearly illustrated .in Figures 1, 2, and 4. L
The table top formed by the two receptacles it is supported above and between a pair of seat assemblies each comprising a planar seat element l5 and a pair of supporting legs i6. The legs it are hingedly connected. to the undersurface of the seat element i5 by hinges indicated by. the reierence character il'. The legs it herein shown as substantially solid panels obviously `can take any particular shape desired. Each leg is 1rigidly held against movement from its extended position by a brace link It, each comprising a rod having one end iiXed, but pivotally mounted to the undersurface of the seat element l5 and having the opposite end adapted for engagement with a small bracket carried by the inner surface of a leg I6. Once this latter end of each link is engaged with the bracket, the link will hold the leg in the desired extended position. The hinge members ii permit the legs to be swung from a position in which the saine underlie the seat element i5 to a fully extended supporting posi-ion such as shown in Figure 3, in which position the legs are, as above explained, rigidly braced by the links i8.
Each seat element l5 carries at the opposite ends thereof frame members i9 of a length slightly greater than the width of the seat elements i5. The one end of an elongate rigid link 2| is pivotally secured to the projecting end of each frame element I9, the opposite end of each link 2i being pivotally connected to an end wall Il of the contiguous or adjacent receptacle if?. The pivotal means interconnecting the one end of the link 2i with the frame element i9 may comprise a headed pintle member 23 passed through aligned openings formed in the ends of the frame le and link 2l. The end of the pintle member 23 opposite to the headed end is threaded and receives a nut 2t. The pivotal connections 25 between the links 2l and the end Walls ii may consist of the identical conventional pivot means.
The hinge connection between the receptacles lll and the manner in which the seat assemblies are pivotally connected to opposite sides of the table .formed by the receptacles, permits the table and seat assembly of the present invention t0 be compactly folded into the carrying case shown in Figure 2. Any conventional fastening means, such as indicated at 215, may be used to hold the two receptacles in their fully closed position. A handle member 27 may be secured to one receptacle for conveniently carrying the case formed by the closed receptacles Ill.
When the table is to be used, the fastening means 2B are disengaged and the two receptacles are swung apart to a position in which the adjacent side walls i2 of the two receptacles IG are in facewise engagement. In this position the outer planar surfaces formed by the transverse walls E?, will be coplanar, as clearly shown in the drawing. The legs l5 are now swung outwardly from the seat element it and the brace links I 8 secured to hold the legs against pivotal movement. The two receptacles can now be inverted to allow the seat elements i5 to pivotally move out of the receptacles and into the position shown in Figure 1.
Each seat element i5 is rigidly held against movement relative to the elongate links 2l by a pair of brace links 28 arranged at opposite ends thereof, each brace link comprising a toggle link, the free ends of which are pivotaliy connected to a frame element it and a link 2l, respectively. Stop means carried by each toggle limit movement of the same and act to hold the brace links in fully extended position.
it will be seen, referring now to Figure 4, that pivotal movement ci each of the links 2| is limited by the opposite side walls l2 of the receptacles and the engagement between the upper ends of the links 2l with the side walls tends to hold the table in a rigid supported position. The table and seat assembly in this fully extended position aioids seating accommodations such as are found with conventional picnic tables for the seat elements form benches arranged along the opposite side of the table. t should be noted that the links 2! are connected to the table top at substantially the four corners thereof and thus will, when the seat assemblies are moved to the position shown in Figures l and e, rigidly support the table above the seat assemblies and the table top will consequently take relatively heavy loads applied even at the corners thereof.
If it is desired to more fully support the table top formed by the receptacles i8, means may be provided for supporting the opposite ends thereof, In the illustrated embodiment of the present invention this means comprises a pair of auxiliary legs 2t hingedly mounted at their upper ends to the opposite ends of the wall i2 of one of the receptacles it. Any means desired may be used to hingedly mount the legs 729 to the inner surface of the wall l2 and in the illustrated embodiment of the present invention this means, as best shown in Figure 9, comprises an elongate bolt-like member 3l mounted in a passageway formed in a bearing block 32, iixed to the inner surface of the wall i2, and the wall itself. The opposite ends of the passageway are enlarged to receive, respectively, the head of the member Si and a securing element such as a nut Sil threadedly mounted to the one end of the member 3l. It will be seen, referring now to Figure 5, that the bearing blocks 32 properly space the legs 29 so that the same can be moved into a folded position in which the legs are disposed in a side byy side relationship.
To lock the legs in their extended position, brace toggle links 35 are preferably used and these toggle links may bev similar to the brace links 28, with the free ends thereof connected, respectively, to a leg and the bearing block associatedwith the leg. These toggle or brace links, when the legs 29 are folded into the receptacle, move with the leg into the position shown in Figure 5.`
`When it is desired to collapse the table and s eat yassemblies for transportation or storage, the folding operations are reversed to bring the seat assemblies into the receptacles I to permit the same to be closed to again form the carrying case shown in Figure 2.
As the seating elements I are of a length slightly less than the length of the receptacles I0, the seat assemblies, when the same are swung inlwardly about the pivotal connections 25 and 23,
are movable to a position, referring now to Figure 2, in which the upper surface of the seat elements I5 are in facewise engagement with the undersurface of the transverse walls I3 of each receptacle. In this position' the links 2| lie closely adjacent to the end walls II of the receptacle, as clearly shown in Figure 5, andthe frame members I9 are arranged substantially parallel to the links 2I If the legs I 6 are allowed to remain in their fully extended position, a table is had, referring now to Figure 2, which is rigidly supported directly by the seat assemblies a distance above the supporting surface substantially equal to the length of the extended legs I6. The table top formed by the two receptacles IU will, it is quite clear, be very rigidly supported, for as above explained, the particular link arrangement permits the supporting surface of the seat elements I5 lto be moved into facewise engagement with the undersurface of the transverse walls I3. The table in the adjusted position shown in Figure l is particularly adapted to be used at a beach or other recreational area where informal seating arrangements are desired.
lIn the now preferred embodiment of the present invention, each of the hinge members I4 is preferably so made that the pin 36 is fixedly mounted to the barrel element 3l and is removably mounted in the other barrel element 38. As the adjacent walls I2v are cut away as indicated at 39, it is possible to longitudinally move one receptacle relative to the other to withdraw the pin 36 from the barrel element 38, the cut away portion of the wall I2 allowing movement of the barrel element 3l. l Once the pins 36 have been withdrawn from the barrel elements 38, the two receptacles can be moved apart to form two tables of a height substantially that of a conventional coffee table. Thusifor home use Where it is desired to serve refreshments or other food articles from tables resembling coffee tables the table of the present invention provides these facilities.
As the receptacles can be separated, it is possible, referring now to Figures 'I and 8, to provide an article of furniture resembling a small writing desk. Such an article of furniture can be had by swinging the auxiliary legs 29 intotheir operative position in which they now support the one edge of the receptacle IIJ to which they are connected. The seat member I5 is then swung to its fully extended position with its links 2|, after which the brace members formed by the links 28 can be set to hold the seat against movement relative tothe links 2|. The'one receptacle and its associated elements in this use of the device of the present invention forms a very rigidly supported writing desk.
Although the now preferred embodiment of the present invention has been shown and illustrated herein, it is to be understood that the invention is not to be limited thereto, for it is susceptible to changes in form and detail within the scope of the appended claims.
