may be collapsed into small compass for storage purposes and to be extended at openposition substantially normal to the plane of the table. More specifically, my invention relates to the provision, in a folding table,
of means for securely hinging the legs to the table and of simple means for locking.
the legs firmly in open position and yieldingly in folded position. One object of the invention, 1s the provision of an improved table rim, of simphfied construction, providing a seat in which the table top may be arranged and a flange to which the legs may be attached and within the zone of which the legs may be folded.
Another important object of the invention is the provision of a hinge construction comprising a bracket secured to the table and a pintle carried in a flan e formed in the leg and pivoted in the bracl ret, the pintle, flange and bracket being of substantial length in the direction of the axis of the hinge whereby wabbling of the leg is prevented.
Still another object of the invention is the provision of a latch of simple construction, positive action and rugged construction adapted to secure the leg of a folding leg table firmly in open position.
Still another object of the invention is the provision of a leg, hinge bracket adapted for arrangement in the corner of a table of the folding leg type to pivotally support the upper end of a leg, and having a formation therein adapted to engage the lower end of another leg when in folded position whereby to support it in closed position.
A still further object of the invention is the combination of the novel table rim, hinge, and latch in a folding leg table of simplified construction whereby a sturdy and easily operated folding table maybe made cheaply and at the same time having a sightly appearance and giving satisfactory operation over a long period of service.
Numerous other objects and advantages of 5 the invention will be apparent as the invention is better understood from the following description which, taken in connection with the accompanying drawings discloses a pre ferred embodiment of the invention.
Referring to the drawings:
Figure 1 is a prospective view of a folding leg table embodying my invention showing the legs in open position;
Figure 2 is a bottom plan view of the table shown in Figure 1;
Figure 3 is an enlarged vertical cross section taken substantially along line 3-3 in Figure 2;
Figure 4 is a horizontal cross section taken substantially along the line 44 in Figure 3;
Figure 5 is a view similar to Figure 3 with the table legs in relatively folded position;
Figure 6 is a view similar to Figure 4 with the table legs in relatively folded position;
Figure 7 is a prospective view of the hinge construction as it appears in place in the table; and I Figure 8 is a prospective view of the individual parts comprising the improved hinge construction of my invention.
To illustrate my invention, I have shown on the drawings a folding leg table having a top 11 and separating legs 13 pivotally mounted to the table top being adapted to be arranged in substantially normal open position or to be folded within the zone of the table top to form a compact folded table when not in use.
The table top comprises the peripheral rim 15 which is formed from a single strip of material suitably cut and configurated to form the periphery of the table top, being in the illustrated embodiment, bent to form a square table rim. The body of the rim lies in a substantially vertical plane, and the upper edges of the rim strip are bent inwardly as at 19 to form a rounded corner. The upper edge is thence bent vertically downwards along a line of bend 21, Figures 3 and 5, thence normally inwards along a line of bend 23' to provide a ledge 25. The lower edges of the strip are bent inwardly at right angles to the main body of the strip along a line of bend 27, thence downwardly parallel with the plane of the main body along a line of bend 29, thence backwardly along a line of bend 31 and extend upwardly to the'ledge 25. The extreme lower edge portions are finally bent inwardly along a line of bend 33 to provide a ledge 35 parallel and adjacent to the ledge 25 which ledges are secured together as by welding or any other convenient means, to provide an annular table top supporting flange.
ledge 35 inwardly beyond the inner edge of the ledge 25 andfold the extended ledge portion over to enclose the outer edges of the ledge 25, said folded portion being secured to the ledge 25 by spot welding or any convenient manner.
The table top consists, in the illustrated embodiment, of a square board which may be formed of any convenient material and a suitable cover 39 which is wrapped about the 'board. The table top is then arranged in the seat formed by the ledges 25 and 35 and is secured in position therein by convenient fastening means such as the nuts and bolts 41 illustrated.
In the table of my invention, the folding legs are pivoted to the rim 15 at each of the four corners of the table and are arranged to fold into the zone of the peripheral rim beneath the top supporting led e thereof. The legs are supported in brac ets which in turn are secured to the inner surface of the rim immediately beneath the top supporting ledge. Each bracket is formed from a single .strip of metal suitably cut and bent to probracket is provided with an offset protuberance 53 formed at the lower edge of the portion and the end 49 is offset to provide a cam surface 55 therein. The lower edge of the end 49 is provided with a notch 57 adjacent the cam surface 55. The bracket is arranged in the table with its upper surface 45 engaging the exposed lower surface of the edge 35,'its side 47 engaging the single surface of the rim 15 and the end 49 engaging the single surface of the adjacent side of the rim. The bracket portions 45, 47 and 49 may be secured to the rim 15 by any convenient means, although I prefer to use spot welding or the like. The legs 13 comprised tubular of the leg adjacent one side thereof, each side is extended to form a lateral flange 67 lying in the plane of said side. This flange has an upper edge 69 which is curled over to form a journal, the axis of which ,is in alinement with the apertures 61. The journal and the In order to strengthen. this flange, it may be desirable to extend this ears are adapted to support a rod 63 which extends outwardly thereof at each end and is pivoted in holes 65 formed in the spaced end portions 49 and 51 of the bracket. This rod extends through these apertures and is riveted for the purpose of securing it in place. Its arrangement insures a substantially long hinge for the leg, which prevents the leg from wabbling in the plane. of the axis of the hinge. The parts are so arranged that when the leg is. 1n open position, it is arranged at the corner of the .table and when in folded position extends parallel with the side of the rim to which the end .49 of the bracket is attached. A similar bracketis attached at the adjacent corner of the rim with its side 47 secured opposite the lower end of the leg when it is in folded position and the protuberance 53 therein is arranged in position to co-operate with the lower end of the folded leg in order to secure it in folded position, the resilience of the leg allowing it to be sprung over the protuberance which thereupon engages beneath the leg and maintains the same in folded position within the zone of the rim. Y
In order to secure the leg of the table'in open position, I have provided an improved latch construction which comprises a detent arranged in the upper portions;.of the leg and a co-operating keeper formed in the bracket. The keeper comprises thecam surface 55 and the notch 57 heretofore described. The detent comprises an arm formed from a metal strip and having a detent portion 73, a body 77 and a handle 79. The detent and the blade are arranged through slots 71 formed in the side walls of the-leg, and the body 77 is pivoted by means of a 'pin 75 engaging through an aperture 7 5 formed in the flange 67, the handle 79 extending beyond the lower edge of the lateral flange. The detent is normally urged in an upward direction, that is to say towardthe axis of the hinge, by means of .a spring 8l-secured as at 83 to the detent body porti'o'li 77, within the leg and to the hinge pin- 63;: The outer end of the detent 73 extends outwardly of the leg and engages the cam surface 55. When the leg is arranged in fully opened position, the detent registers with vthe notch 57 and engages therein under the influence of bracket. When it is desired, to open the leg,
the lower end is sprung from behind the protuberance 53 and the leg is then swung or moved t0 open position, the detent 73 riding ill upon the cam surface 55 and being guided Having thus described my invention what I claim as new and desire to secure by Let ters Patent is: a
