Application May 6, 19

2 Claims.

These improvements are on my former application, Serial No. 546,543 series of 1925, applied for June 24, 1931, now Patent No. 1,905,282 of April 25, 1933.

Q This invention relates to a folding table adaptable for various purposes and which will be compact when folded to permit convenient storing in a small space and Will be easy to carry from one place Vto another and has for the primary object,

l the provision of a collapsible top and folding legs so arranged that the legs will automatically assume supporting position when the top is extended and will fold within the top when the latter is collapsed, thereby providing a table rel quiring only minimum effort on the part of a person to extend for use or to collapse for storage.

Another object of this invention is the pro- Vision of operating means for the legs, and the provision of operating means for locking the legs in extended position, effected by the movements of the .top for folding or extending the legs in accordance with the collapsing and extending of the top and which will effectively brace and hold the legs in supporting position against accidental folding when the table is in use.

A further object of this invention is the provision of a folding table of the above stated character which will be simple, durable and efcient and which may be manufactured and sold at a 3o comparatively low cost.

With these and other objects in view, this in- Vention consists in certain novel features of construction, combination and arrang-ement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is had to the following description and accompanying drawings, in which Figure 1 is a bottom plan View illustrating the operating means between the table top and the legs, and illustrating the operating means between the extending of the legs and the locking device for the legs in extended position.

Referring in detail to the drawings, the numeral 22 indicates the tops of the two sections of the table being suitably secured to the side and end members 1 and 23 respectively. The inner side members are connected by hinges 17 on which the two sections may be swungto and from each other for the purpose of collapsing or extending the table top. The outer side members are equipped with hand grips 2 for carrying purposes, and all four side members are circularly recessed near the inside ends to receive the small ends of the round 4.

When the table is extended, the outer ysurfaces of the inner side pieces 1 Vcome into an abutment engagement and provide a continuous supporting surface for the table. When .collapsed, the bottom surfaces of the end members 23 come into abutting 4engagement with the bottom surfaces of opposite .end members 23, and the bottom surfaces of the outer .side members l come into abutting engagement, and the bottom surfaces of the inner side members l come into abutting engagement, providing a compact unit.

To the inside surface of the end members 23 and the top 22 in the location illustrated in Figure 1 are attached suitably the angle channel guides 5. The rounds 4 with legs 3 attached as shown in Figure 5 are placed in parallel position With the end members 23, with the small ends of the rounds 4 set into the rounded recesses provided for them near the ends of the side members 1. The legs 3 and the dowel posts 9 are located on and in the round 4 as indicated in Figure 5 and Figure 13, the legs and the doWel posts 9 in a vertical position or right angles to the top 22, in the locations indicated on the rounds 4 in Figure 1 When the legs are extended.

The pins of the quarter round sliding mechanisms 6 and 7 are engaged in channels of the angle channel guide 5 in such a manner that the doWel post 9 engages With the slotted guides 26 and 25, with respect to` the positions as shown in Figure 1, and with the lever stops 28 and 27 nearest the inner surface of the top 22 and the anchor posts 24 near the ends of quarter round mechanisms 6 and 7 most adjacent to the inner side members 1. Y

To the inner surface of the top 22 are suitably attached with the bracket 15 and other means the leg brace guide tracks 8 parallel with Vthe side members 1 and located as shown in Figure 1 with the slots 3G most adjacent to the end members 23. The leg brace guide tracks 8 slidaoly receive the heads 32 of the leg braces 10. To the inner surface of the top 22 and located as shown in Figure 1 are suitablyT attached the pivot tables ll with the stops 29 located in the general direction of the tables corners.

On the pivot tables poles 11 are placed the lever arms 12 and in turn to the lever arms l2 are freely attached for swivel action the locking arms 13 and 14 with respect to their respective positions as shown in Figure 1 with their shortest sides most adjacent to the end members 23. The locking arms 13 and 14 are inserted in the guide brackets 16 suitably attached.l to top 22 which insure the locking arms 13 and 14 ventering the slots 36 in the leg brace guide tracks 8.

To the inner surfaces of the inner side members l are suitably attached the anchor posts 20 and 21 with regard to their positions as shown in Figure 1. Between these anchor posts 20 and 21 and the anchor posts 274 are freelyattached the arms 19 and 18 with regard to their positions as shown in Figure 1.

When it is desired to place the table in use, the two sections of the table are swung apart in the act of extending the table, from a collapsed manner as indicated in Figure 3, the anchor posts 20 and 21 are caused to pull on Vthe arms 19 and 18, by reason of their proximity to the seat of the whole action. The pull on the arms 19 and 18 is in turn transmitted to the quarter round sliding mechanisms 6 and 7 through the anchor posts 24. Ilhis pull in the direction of the inner side niembers 1 causes the quarter round sliding mechanisms 6 and 7 to slide in the angle channel guide 5 causing the slotted guides 26 and 25 to force the dowel pin 9 to ride'in the direction of the slots 26 and 25. The dowel pins 9 in riding in the slotted guides 26 and 25 rise `from a position parallel to the tops 22 to a position at right angles to the top 22. As the action of the dowel pin 9 and the leg 3 arevconeurrent in action on the round 4, the leg 3 comes to a right angle position to the top 22 or that of being extended. `As the leg 3 rises the brace 10 moves slidably by means As the quarter round sliding mechanisms 6 and 7 move in the general direction of the inner side members the lever engagers 28 and 27 engage with the free end of the lever arms 12 which pivot on the pivot pole of pivot table 1l, causing the locking arms 14 and 13 to be thrust by reason of a swivel action through the guides 16 and into the slots 30 of the leg brace guide tracks 8, locking the head 32 of the leg brace 10 between the stops 31 and the ends of the said locking levers 14 and 13.

The collapsing of the table is exact reverse process with legs 3 assuming the position as shown vin Figure 3, partially encasing the leg braces 10 Vwhich have in the reverse action been freed by the locking' arms 14 and 13, allowing the heads 32 to slide towards the opening end of leg brace guide track 8. Y

` As the quarter round sliding mechanisms 6 and 7 return in the general direction of the outmost side members 1 the free ends of lever arms become disengaged With the receding lever engagers 28 and 27. The free ends of lever Aarms 12 are carried by the quarter round sliding mechanism to a stopped position against the stop 29, preventing the lever arm 12 from turning too far so as not to fail engagement with the lever engagers 28 and l2'?. As the lever arms 12 move to this stopped position against stop 29, they activate the locking arms 14 and 13 to Withdraw from the slots 30 and to free the heads 32 of the leg brace 10.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and Vscope of my invention, as claimed.

Having thus described my invention, what I claim is:

' l. A folding table comprising a folding sectional top, legs pivoted to the sections of said top, leg brace arms attached to legs, heads offbrace arms slidable in guides attached to sections of top, port holes in said brace arm guides, locking levers pivoted to sections of top, so situated as to become engaged with lever engager slots in `quarter round sliding mechanism, thus causing locking levers to enter port holes of leg brace arm guides or to be pulled from port holes of leg brace arm guides, thereby, automatically locking or unlocking said leg brace arms by folding or unfolding sectional top.

2. A folding table comprising a sectional top, said sections having folding relation, legs attached to rounds with dowel ports pivoted to the sections of top, quarter round sliding mechanism seating over rounds and sliding in angle channel guides attached to sections of top, said dowel ports extending through slotted guides in quarter round sliding mechanism, said quarter round sliding mechanism attached by arms to opposite sections of top by means of arm posts, thereby causing the legs to move into folding position when sections of the top are folded and to move the legs into supporting position when the sections of the top are unfolded.
