FOLDING FURNITURE LEG Fi'led Sept. 22, 1954 l .2 Sheets-Sheet 2 v j W@ Y Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE 4 Claims.

This invention appertains to furniture, and more particularly to folding furniture legs of the type particularly adapted for use in conjunction with folding card tables and the like.

One of the important objects of my invention is to provide a novel brace and lock for the swinging legs of card tables, whereby when theY leg is swung to its operative position, the same will be automatically held against accidental swinging movement until manually released.

Another salient object of my invention is the provision of vmeans for manually releasing the lock or latch by movement of the brace itself, whereby the necessity of actuating extraneous catches, latches, andthe like, is eliminated.

A further object of my invention is the pro.- vision of means for creating a tension at all times between the brace and the leg, whereby accidental movement ofthe leg, after the same has been moved to its folded position, will be prevented.

A further object of my invention is the provision of a, leg brace having pivotal connections with the table top, and sliding and swinging engagement with the leg carried guide member, the brace having a keeper notch therein, with resilient means normally urging the brace and leg guide member towards one another so that when the leg guide member reaches the keeper notch, the same will ride therein to hold the leg securely against further accidental movement. Manual movement of the brace against the tension of the resilient means functions to re- -lease the guide member from latching engagement with the WallsV of the keeper notch, Whereby the leg can be quickly swung to its folded position.

A still further object of my invention is to provide a novel brace and latch for the swinging legs, of a card table, which will be of an exceptionally simple and durable construction, and which can be incorporated with card tables at a small cost.

With theseand other objects in View, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1A is a. fragmentary vertical section through one corner of a card table, illustrating the use of my improved leg brace and latch, the leg being in its partly opened position, and broken away to more clearly illustrate the connection between the same and the brace.

Figure 2 isa view similary to Figure 1, showing the position of the novel brace and latch when the leg is in its completely folded position, the leg being broken away to more clearly illustrate the brace.

Figure 3 is a fragmentary side elevation of the i5 leg and brace, looking from the opposite side of Figure 1, showing the leg in its operative extended position.

Figure 4 is a detailed section taken on the linev 4--4 of Figure 1, showing the connection between 10 the tension spring and the brace the view being on a larger scale than Figure 1.

Figure 5 is a fragmentary sectional View similar to Figure 1, showingV another form of my improved brace and latch. 15

Figure 6 is a fragmentary side elevation showing the modified form of latch with the leg in its extended operative position, the View being taken from the opposite side of Figure 5.

Figure 'l is a detail section taken on the line 20 'l-l of Figure 5, illustrating the connection between the leg and the novel brace and latch.

Figure ,8 is an enlarged fragmentary bottom plan view of one corner of a table, illustrating that` form of brace shown in Figures l' to 4,V in- 25 clusive applied thereto, the table leg being in its partially open position.

Figure 9y is an enlarged fragmentary vertical sectionalview, looking at right angles to Figure 1 o-f the drawings, and showing that form of brace 30 illustrated in Figure 1.

Figure l() is an enlarged fragmentary vertical sectional View, looking at right angles to Figure 5, and illustrating that form of brace shown in Figure 5. 35

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter T generally indicates a card table, which, as shown, includes the table top l0 having side 40 rails Il secured thereto. Each corner of the table top supports a swinging leg l2, and for the purpose of simplicity I have only illustrated one corner of the table with one leg. The leg I2 is pivotally connected, as at i3, to a corner bracket 45 lf3', which can be of any preferred construction.

As heretofore stated, one of the important features of my present invention is the provision of the use of the novel brace i4 for the leg l2. In Figures 1 to 4, inclusive, the brace lll is in the 50 nature of a metallic strap, and the same has its upper end offset and pivotally mounted upon a pin |5' rigidly connected to one of the side rails Il of the table top. A longitudinally extending guide slot IB is formed in the brace I4, and one 55 wall of the Slot at its outer end is provided with -a keeper notch I1', for a purpose which will be later set forth. The leg I2 carries a guide pin or rivet I1, which is slidably mounted within the slot I6. Consequently, during the opening and closing movement of the leg I2 the pin I1 rides in the slot I6 and swings the brace on its pivot pin I5. The outer end of the pivot pin or rivet I1 is provided with a head I8 which engages the outer face of the brace.

Extending longitudinally of the brace strap I4 is a flat resilient leaf spring I9, the use of which forms one of the salient features of my invention. This leaf spring extends the full length of the slot I6 and at an angle thereto, so that the outer end of the spring normally lies in close proximity to the keeper notch I1'. The inner end of the leaf spring is rigidly secured to one face of the brace strap in any preferred manner. AS shown, the inner end of the leaf spring is provided with a head 20,V which lies flush against one face of the brace strap I4 at the inner end thereof, and the pivot pin I5 extends through the head. The inner edge of the spring can be provided with a laterally extending lip or tongue 2|, which is received in a slot 22 formed in the brace I4. This prevents swinging movement of the spring on the pivot pin I5.

Due to the angular position of the inner edge of the spring I9 relative to the walls of the notch, the guide pin or rivet I 1 of the leg normally bears against this edge of the spring. Consequently, a friction or drag is created on the pin I1 at all times, which functions to prevent accidental swinging movement of. the leg incident to the carrying of the table when the leg is in its co1- lapsedV or folded position. The tension on the guide pin I1 increases as the pin reaches the outerend of the slot I6, and thus when the leg reaches its extreme extended operative position, the spring will be flexed to such an extent as to forcibly urge the pin I1 into the keeper notch I1', and the tension of the spring is such as to securely hold the pin I1 'in the keeper notch. Consequently, the tableleg is securely held in its oper-ative position.

When it is desired to release the leg, and to swing the same back to its closed or collapsed position, it is merely necessary for the operator to push on the brace strap I4 and against the tension of the spring I9, which will move the brace away from the pin I1, allowing the leg to be swung on its pivot I3.

From the foregoing description, it can be seen that I have provided an exceptionally simple and durable means for bracing the leg and holding it securely in extended position.

Obviously, the brace itself is open to certain modifications, and in Figures 5 to 7, inclusive, I have shown another preferred form of my invention. In these figures the numeral 25 indicates the table top, and 2S the side rails thereof. The table leg 21 is pivotally connected, as at 28, to a corner piece 28'. The leg 21 in this form carries a U-shaped staple or guide member 29 in lieu of the guide pin or rivet I1, and this U-shaped staple embraces the brace strap 30. The upper end of the brace strap 3E) can be off-set, and is pivotally connected to the table top by means of a pivot pin or bolt 3 I. The outer edge of the brace strap adjacent to its lower end is provided with a keeper notch 32, which is adapted to receive one leg of the U-shaped guide 29, when the leg is in its extendedl operative position, as shown in Figure 6 of the drawings.

Rigidly secured to one face of the brace strap 33 is a at resilient leaf spring 33. 'Ihis leaf spring extends longitudinally of the strap 30, and' at an angle to the side edges of the strap, terminating adjacent to the outer end of the strap. In securing the spring 33 in position, the same can be provi-ded with a head 34 at its inner end, which can be securely riveted, as at 35, to the brace strap. The extreme free outer end of the spring has formed thereon the laterally projecting nose 36, and it is to be noted that this nose lies adjacent to the keeper notch 32.

In operation of this form of my invention, when the leg is swung to its open position, one leg of the U-shaped guide will ride on one edge of the leaf spring, and create a tension thereon. This tension increases as the guide reaches the outer end of the spring, and as the guide 29 rides on the nose 36, the other legs of the guide and the strap are moved toward one another, and the last-mentioned leg of the guide will snap into the keeper notch 32. This will effectively hold the leg in its open extended position against accidental swinging movement. When it is desired to move the leg back to its folded or collapsed position, the brace is swung against the tension of the spring 33 until the guide rides out of the keeper notch 32, at which time the leg can be swung on its pivot.

Changes in details may be made without departing from the spirit or scope of my invention, but what I claim as new is:-
