My present invention relates generally to folding tables, and more particularly to card and other small tables, the supports of which are foldable against the top thereof in order that the tables may be stored in disuse in minimum space. Various tables of this general character have been manufactured and are now in common use, but it is necessary in the ordinary construction to fold each leg separately and it is one of the objects of my invention to provide a construction by means of which the legs may be simultaneously shifted between folded and operative positions with readiness and ease, and in which the legs in their operative position may be double locked to prevent wabbling or other unsteadiness of the table in use.

In the accompanying drawings 'which illustrate my presentinvention, and form a part of this specification Figure 1 is a perspective. view of my improved folding table, with the legs extended. in effective position;

Figure 2 is a'bottom plan view ShOWIDg the legs folded;

Figure 3 is a vertical section through a i portion of the table top and through one of the legs with the latter in the extended or operative position 5 Figure 4 is a slmilar' view with the leg folded;

Figure 5 is a detailed perspective view of one of the leg brackets and its pivot member;

Figure 6 is a rear elevation thereof; Figure 7 is a detailed perspective view. of one of the leg slides with the adjacent end of one of the brace bars, and,

Figure 8 is a detailed perspective view of one of the pivoted latch members and its keeper. I Referring now to these figures my invention proposes a folding table including a top' 10 around the lower surface of which adjacent to its edge a depending rail 11 15 secured. Tables of this character are usually of rectangular shape, and as a consequence I mount a series of brackets 12 within the corners of the rail 11, each bracket having a fiat body apertured as at 13, and as particularly seen in Fig. 5 for the rece tion of fastening members, the latter of w ich'enter the material of the table top 10 and serve to securely anchor the body of the bracket firmly against the undersurface of the top.

Each bracket is preferably shaped to fit the corner of the rail 11,v and each bracket has depending cars 14, spaced apart for the recelption of a pivot member 15 therebetween. T is member, which is pivoted to the ears by a pivot pin 16', has a reduced extension 17, and is cut away so that when seated against the body of the bracket 12 with its reduced extension 17 at right angles to the said bracket body, a recess is formed between the cars 14 for a purpose which will be presently described. I

The reduced extension 17 of each of the pivot members 15 is adapted to enter one end of a tubular leg 18, to which it may be .rigidly connected as by means of a transverse rivet 19 best seen in Figs.'3 and 4, and each leg is preferably composed of two end wise abutting sections, its outer section being relatively short and connected to its inner portion by means of an external coupling ring 20, the latter adapted to form astop member adjacent to the outer or lower end of the leg for a purpose, which will be' presently described.

Upon each of. the legs 18 a slide member 21 is sleeved for movement along the leg between its inner end and its coupling ring or stop member 20, and each slide 21 has laterally projecting spaced apart ears 22 to receive therebetween one end of its respective brace bar 23. I

A pair of brace bars 23 are employed as best shown in Fig. 1, in crossed relation,

with their ends pivotally connected by pivot pins 24, with the cars 22 of the slides 21 of diagonally opposite legs 18 and these brace bars are preferably connected to one another at their point of crossing as at 25, permitting them to move in unison. Moreover, as pla-in 1y seen, each of the brace bars is rigid from slides 21 are down on the legs 18 and against the coupling rings or stops 20, upon which end to end and as a consequence when the the slides rest. with the legs in operative posi- I tion, it is not possiblefor the legs to flex toward and away from one another. On the other hand, it is simply necessary to press the brace bars 23 inwardly toward the lower surface of the table top until the slides 21 are adjacent to theinner pivot members 15 of the le s, whereupon the legs can be folded inwardly upon the pivots 16 of the pivot members 15 to the folded p sition shown in Fig. 2. It is also preferable that the le s. in their effective position. h additionally the other, is allowed.

It is furthermore obvious that in view of I movable on said legs clnstance becomes simple and easy.

locked by means of latch pieces 26 pivoted at one end at 27 to the rail 11 of the table top so as to extend across the corners of this rail, these latch pieces 26 being formed of spring metal so that they may be laterally flexed in order toextend their free ends over notched keepers 28 secured to the inner surfaces of the table rail 11 and into the notches 29 of which the free endsof the latch pieces are engageable to thus partially embrace the legs and firmly hold the latter in the corners of the rail 11.

It is thus obvious that when the brace bars are shifted inwardly after release of the latch pieces 26, until the slides 21 are adjacent to the pivot members 15, the pivots 24 between the ends of the brace bars and the slides are so near the pivots 16 between the pivot members 15 and the bracket arms 14 that the former can readily move partially around thelatter and in permitting folding of the legs inwardly and in spite of the rigidity of the brace bars 23 and it is furthermore obvious that the conformable shape of the cars 22 and structure of the pivot supporting brackets 12 are such that this movement of the pivots, when partially around the structure of the legs 18 and the manner in which these legs are adapted to be joined to the pivot members and to the slides, the matter of assembly of the parts in the first T e structure as a whole is strong, and durable, without unnecessary complication, is susceptible of ready manipulation to and from operative position, and is furthermore comparatively inexpensive.
