FOLDING TABLE Application filed May 15, 1929. Serial No. 363,204.

i'icient table having foldable legs and of the generally designated as card tables; and generally stated, the invention consists of the novel devices, combinations of devices and arrangement of parts hereinafter described and defined in the claims.

The table top comprises a marginal rectangular frame and a cover board rigidly corners oi the frame and are arrangedgto be held against swaying movement wheriE-operative by oblique braces extending in planes at right angles and arranged in a novel manner hereinafter described.

it accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Fig. 1 is a bottom plan View showing the v table legs in folded positions;

Fig. 2 is a fragmentary perspective showing one corner of the table and one leg turned to operative position with the table being shown as turned upside down;

Fig. 3 is a fragmentary section taken on the line 3-3 of Fig. 2;

Fig. 4 is a section taken on the line 44 of Fig. 8; and

Fig. 5 is a detail in section on the line 55 oi Fig. 2.

The marginal rectangular frame, as shown, is made up of four wooden bars 6, rigidly connected at their corners by reinforcing hinge-acting metal brackets 7 riveted or otherwise rigidly secured to said bars and having ofi'set U-shaped. seats in which the ends of the table legs 8 are seated and pivotally connected to the respective brackets by nut-equipped bolts 9 or the like. The legs are thus pivoted so that each will fold parallel to one adjacent side bar of the rectangular frame 6 but spaced slightly from said parallel side bar. Each leg 8 is connected to the side bar 6 to which it will fold in parallel relation by a toggle-acting brace made up of two flat metal straps 1O pivotally connected at 11 and pivotally connected to 1 the respective legs and side bars at 12 and 13. The overlapping ends of the toggleforming strap 10 are provided with frictional engaging indentations 14 that prevent accidental buckling of the toggle-acting brace.

Extending in planes at right angles to the toggle-acting braces 10, the legs are connected to the side bars 6 to which they are at right angles when turned to folded positions, by rigid or non-collapsible leg braces 15 in the form of still round rods which, at their outer ends, are bent laterally at 16 and extend directly through perforations in the respective legs 8. The bent ends 16 afi'ord trunnions that, at their outer ends are riveted at 17 and hold washers 18 directly against the cooperating legs. At their inner ends, the braces 15 are bent at an angle and are eX- tended through and swivelled in outstanding flanges of angular anchor brackets 19 that are rigidly secured to the adjacent side bars 6 by rivets or otherwise. The rods 15 are thus swivelled to the brackets 19 approximately on the lines of the projected axes of the co-operating legs pivots 9. The inner ends of the brace rods 15 are held in swivelled relation to the flanges of the brackets 19 by having portions thereof stamped and expanded at 20 and 21 on opposite sides of the outstanding flanges of the brackets 19, best shown in Fig. 3.

With this arrangement, when the toggleaeting braces 10 are straightened out, as shown in Fig. 2, the table legs will be very rigidly held against lateral movements in all directions. When the collapsible braces or toggle-acting members 10 are buckled together, the legs will fold substantially against the table top, eachin parallel relation to an adjacent side bar 6 and the folded toggles will occupy positions in the spaces between the folded legs and adjacent side bars afforded by the oilset portions of the angle brackets. In the folded position it will be noted that the free ends of each leg overlies a rigid brace 15 which, due to their con nection with the forward sides of the legs, assume positions substantially against the table top. It will be seen that through this relation of parts the table may be very quickly set up as manual operation of any one of dil the legs will cause the angular rigid brackets to raise the free ends of the other logs from within the marginal frame 6, where they may be readily grasped and swung to perpendicular positions.

The table described, while of simple and rigid construction, may be very quickly set up or knocked down and may. as is obvious, be manufactured at very small cost.

10 \Vhat I claim is:

1. The combination with a table top having a rectangular marginal frame projecting below the top hoard thereof. corner brackets applied in the four angles of said marginal 11' frame, table legs pivoted to said brackets and adapted to fold into parallel relation, each to an adjacent side bar of said marginal frame, toggle-acting braces connecting said legs to the frame side bars adjacent'to which they fold in parallel relation, anchor brackets secured to the frame side bars and extending at right angles to the sidebars adjacent which the respective legs fold in parallel relation, said anchor brackets having imvardly-projecting flanges, and brace rods provided with outturned ends passed directly through the respective legs and having inner ends extended through and swivelled to the flanges of said anchor brackets, the inner ends of so said brace rods having displaced portions on opposite sides of the respective flanges to hold said rods against endwise movements in respect to the anchor brackets to which they are swivelled.

2. A folding table comprising a top having a depending marginal frame. legs hinged within the corners of the frame adapted to be folded adjacent to but spaced from the frame, a collapsible brace between each leg and an adjacent side, brackets secured to each side of the frame, a rigid brace having one end pivoted to a bracket and its other end connected to a leg, whereby upon folding of the legs each of the pivot points of the brackets will be found to be located intermediate a leg and a side of the frame.

A folding table comprising a top having a depending marginal frame, legs hinged within the corners of the frame so as to fold adjacent to but spaced from the inner sides of the frame. a collapsible brace connecting each leg and its adjacent frame side, anchor brackets secured to the frame and each having a flange substantially at right angles thereto, a rigid brace for each leg having one end pivoted to the leg and its opposite end to a flange so that upon folding of the legs each of the pivot points of the flanges of the brackets will be found to be located intermediate a leg and a side of the frame.

In testimony whereof I affix my signature.

JOHN E. KALGREN.
