9 Claims; (Cl. 155-124)- The present invention. relates to foldable picnic tables and has for an object to provide a combination seat and table group, which, when not in use, may be' foldedin'to a compact traveling unit which.v may be placed in the trunk of an automobile for ease of transportation to and from the picnic area.

Another object of the present invention is to provide a picnic tableof the foldable type wherein all of the components are physically connectedwhen in use and during storage or transportation whereby components cannot be misplaced or lost.

A further object of the present invention is to provide a unit easy to assemble, set up and extremely economical in construction.

With the foregoing and other objects in view, the invention will'be more fully described'hereinafter, andwill be more particularly pointedlout in the claims appended hereto. 7

Figure 10 is an exploded fragmentary perspective view of the hinged connection of a table top to the table frame.

Figure 11 is a fragmentary perspective view of the swivel connection of a seat to the table frame.

Referring more particularly to the drawings and for the moment to Figure 1, 20 and 21 designate foldable members of an end support. Each member has a table top support 22, 23, an intermediate support 24, 25, a base 26, 27 and a seat support 28, 29. The free ends of the supports 22, 23 may be bent to define downturned necks 30, 31. Two of the above described units are joined by a locating rod 32 over which slides a pair of sleeves 33 and 33 The upper portions of the foldable members 20, 21 are hinged to the sleeves 33 and 33 by hinges 34, 35 one plate of each of which is secured to the sleeve and the other plate of each of which is secured to one of the down turned necks 30 and 31. As best seen in Figure 8 States Patent 2,81 1,197 Patented Oct. 29, 1957' the lower. portions of the foldable members 20, 21 are hinged together by hinges 36, 37 one plateof each of whichis secured to the bottom portion. of the. intermediate support 24,25 while the other plate. is: pivoted to a crimped end- 38'of one member 39 of a telescopic. support brace, the other member of the brace. is pivoted at- 41 to-a plate 42. secured to the locating rod 32. The. hinge plates are placed to. permit the members to travel. inwardly of the rod 32 so that. the seat supports 28, 29 are outermostwhen. thetable is in the position shown'in Figure 6; The telescopic. support braces 39, 40 may be locked. in the extended position by pins 43, passing. through. selective openings in the members 39,.40.

Since the structure of Figure 1 is constructed the. same ateachend, the lower left handend has been described-in detail and is identical to the upper right hand end-whose corresponding parts are identified bythe same" reference numeralwith the exponent a added-thereto- The table tops 44, 45 are rectangular and extend beyond the end supports. These'tab1etops44, 45- are joined to the support foldable members 20 and 21 (see Figure 10-) by a sleeve 46 secured to the members 20, 21 upon which is carrieda collar 47 having an upstanding projection 47A whichrotatably receives a swivel pin 48' carriedby bracket 44B. having. its. shaft 48A rotatably journaled in the projection 47A. Theswivel pin 48'- isconnected'torpermit the table topto pivot about a pin. which is: secured at each end in anangle bracket 51 securedinslots 44A and 45A. of the table tops 44,45 The tops 44,.45 may partake of two. movements simultaneously byrotatingabout: pivot pin.48B, swivel shaft 48A and rotating about the sleeve 46;

The seats 52, 53, as best seen in Figure 11,.are secured for swivel and pivotalmovement to the seat support 28; 29,. as by a sleeve 54 over which rotates a collar 54A havingv a lug 54B for rotatably journaling the shaft of a swivel pin 54C which in-turn is connected by a pin: 514E, about which the same pivots, secured inplates 54D rigidly retained in. the slots 52A. and? 53A byscrews or the like. Theseconnections permit of rotary: movement of the seats 54, 55.

When it is desired to erect the table from the position of Figure 6 to that of Figure 2, the two sleeves 33 and 33 are grasped and slid toward the ends of the locating rod 32 and the telescopic sections 39, 40 are extended until the hinged adjacent pairs of foldable members 20, 21 assume the position of Figure 1. The pins 43 are then inserted through the telescopic strut sections locking the same in position and holding the unit in assembled condition. The table tops 44, 45 are then rotated through an arc of the order of 270 degrees so that they rest upon the table top supports 22, 23.

During the erection of the table the collars 54A have rotated from the horizontal to the vertical plane and rotated about the axis of the pivot pin 54E to place the seats 52, 53 in their positions upon the seat supports 28, 29 as best seen in Figures 2, 3 and 4.

The reverse procedure just described is employed to fold the table into a compact unit for transportation. Starting with the removal of the pins 43 the sleeves 33 and 33 are urged toward the center of rod 32 after the table tops 44 and 45 have been rotated 270 degrees to clear the top of the unit. The foldable pairs of members 20 and 21 fold inwardly to the position shown in Figures 5 and 6.

While I have illustrated the form of invention as being made of tubing, solid or sheet materials may be employed so long as the relationship of the elements set out is preserved. The preferred embodiment is made of aluminum tubing and has either plastic or wooden seats and table tops although I do not restrict myself to these materials.
