'This invention relates in general totables artieularreference to a table in the zone of the table top whereby the table fiiaybecollapsed into small compass for storage purposes and to be extended at open 051- .tion substantially normal to the plane o the table. More specifically; this invention rea lat es to 'theprovision, in a folding table, of
- folded position. a 7' The primary objec of the present invenmeans for securely hinginf'g the legs to'the table and of simple means r Iockin thelegs v firmly in open position: and yiel ingly 111 tion is to provide a new and improved table having a novel leg construction and latching means. 8
"Another. important object of the invention is the provisionuof a hinge construction comprim'ng'a bracket secured to the table and a pintle. carried in a flange formed in the leg and pivoted in the bracket, 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.
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 30 in open position. A further 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.
i A still further object of the invention is the combination of hinged legs and latches for a folding leg table of simplified construction whereby a sturdy and easily operated folding table may be'made economically, and at the same time having a pleasing appearance and giving satisfactory and efficient operation over a long period of service.
Numerous other objects and advantages will be apparent throughout the progress of the following specifica ion.
The accompanying drawings illustrate a selectedembodiment of theinvention and the views therein are as follows:
Figure 1 is a erspective view of a folding leg table embo ying the present 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 4-4 in Figure 3; v 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 perspective view of the hinge construction as it appears in place in the table; and I Figure 8 is a perspective view of the individual parts comprising the improved hinge construction of the present invention.
The folding table herein shown for the purposes of illustration has a top 11, and separating legs 13 which are pivotally mounted I to the table top. The legs are 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 notin use.
0 The table top comprises the peripheral mm 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 rimlies 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 ofbend 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. The ledges may be secured together as by welding or any other convenient means, to provide an annular table top sup porting flange. In order to strengthen thls llange, it may be desirable to extend this ledge 35 inwardly beyond the inner edge of the ledge 25 and fold the extended ledge portion over to enclose the outer edges of the ledge 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, Figures 2 and 3.
The particular top construction is shown in applicants divisional application, Serial No. 483,400, filed September 22, 1930, for Folding table top.
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 ledge thereof. The legs are supported in brackets 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 provide a hinge portion having a top 45 from which an end 49 and a side 47 are bent at right angles. The edge of the top 45 opposite the bent end 49 is also bent downwardly to provide an end 51. The side 47 of the bracket is provided with an offset protuberance 53 formed at the lower edge of the portion and the end a9 is offset to provide a cam surface 55 therein. The lower edge of the end 49 isprovided 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 port- ions 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 comprise tubular members having a substantially square cross section at their upper ends. Each leg is provided at its upper end with ears 59 having apertures 61 formed in opposite sides of the leg adjacent one side thereof. The leg is constructed to provide a lateral flange 67 which lies in a plane of a side of the leg. This flange has an upper edge 69 which is curled over to form a journal, the axis of which is in alignment with the apertures 61. The journal and the ears are adapted to support a rod 63 which extends outwardly thereof at each end and is pivoted in holes 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. This 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 in 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 bracket is attached at the adjacent cornor 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 cooperate 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.
In order to secure the leg of the table in open position, there is provided an improved latch construction which comprises a detent arranged in the upper portions of the leg and a cooperating keeper formed in the bracket. The keeper comprises the cam 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 75 formed in the flange 67, the handle 7 9 extending beyond the lower edge of the lateral flange. The detent is normally urged in an upward direction, that is to say, toward the axis of the hinge, by means of a spring 81 secured as at 83 to the detent body portion 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 the notch 57 and engages therein under the influence of the spring 81. VVhen it is desired to fold the legs into the zone of the rims, the detent may be released from engagement with the notch by pressing upwardly on the handle 79; This operation releases the detent from the notch whereupon the leg may be swung to folded position, the detent sliding along the cam surface 55, the end of the leg being sprung behind the protuberance 53 of the adjacent 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 to open position, the
The invention rovides a simple, eflicient' easily operated olding table composed of relatively few and simple parts, and can be readily and "economically manufactured.
Changes may be made in the form, construction, and arrangement of the parts without departing from the spirit of the invention or sacrificing any of itsadvantages, and the right is hereby reserved to make all such changes as fairly'fall within the scope of the following claims.
