(29 Kenilworth St., Newton, l‘vIass.) Filed Sept. 25, 1958, Ser. No. 763,250 ~ 11 Claims. (Cl. 311—99) My invention relates to foldable legs for card tables and the like, and it has for its primary object to provide rearwardly curving frontal surfaces 19 of the wall-pro vided cam portions 21}. The rear camming edges 21 of the side wall-provided cam portions 24) slant inwardly and rearwardly as shown in FIG. 2 and terminate at the site of the rearwardly extending wall edge-provided seat 22 which is aligned with and in part formed by the lower edge of the rear, or bight wall 15 of the bracket. As indicated in FIG. novel means which is operable to ?rmly retain individual 10 2 and as will be referred to more fully shortly, this sec end wall edge-provided seat 22 is adapted to be engaged, legs in operative position and likewise in inwardly folded position against the bottom of the table top. The invention contemplates a novel leg pivoting bracket or closely approached, by a leg-carried and spring backed stop 23. This stop 23, along with leg 11, is actuated outwardly by cam surfaces 21 to retain the leg in op member for attachment to the underside of the table top and a shiftable leg-carried abutment which is preferably 15 erative position and in bearing engagement with the low er edge of the bight or rear wall 15 of bracket 13. spring actuated to engage one bracket portion to retain Coming now to the leg-carried stop 23 to which in the leg in operative position and to bear against another cidental reference has been made, FIGS. 1 and 2 of bracket portion to secure it in folded position adjacent the drawing illustrate the leg 11 as having slidable there the under table top surface. An important object of the invention is to provide 20 on the oversized stop-providing sleeve 23 having at its simple, ef?cient and durable, but inexpensive means for the purposes speci?ed which is readily operable and ad mits of the leg being manually swung from one position upper end an endless inwardly extending leg-engaging ?ange 23a and at its lower end an outward reinforcing curl 23b. A leg-carried spring backing member 25, to to the other. A further and more speci?c object is to furnish a novel be presently described, serves to slidably mount the low sleeve form leg-carried stop which is spring actuated to make constant bearing engagement with the leg-pivoting It is to be noted from the full line showing of FIG. 2 that when the leg 11 is in its depending operative po sition, the spring backed sleeve 23 has its inwardly ?anged er end of sleeve 23 on leg 11. bracket and wherein a novel leg carried sleeve concealed upper end 23a in engagement with the bracket-wall stop is provided for a sleeve housed actuating spring. Invention also resides in the leg-pivoting bracket and 30 provided seat 22; and that curved outer portions 23a of the sleeve end engage cam edges 21 to cause the up in various novel features of construction, combination per leg portion to bear against the lower edge of brack and arrangement of the various parts, as will be under et wall 15, as earlier mentioned. The sleeve end need stood and appreciated by those versed in the art, refer not actually engage seat 22, as will be apparent. It is ence being bad to the accompanying drawing showing a now preferred example of the invention. 35 also to be noted that since the leg 11 slants outwardly in its operative position the weight of the table top 10 tends It is to be understood that the drawing disclosure is to retain it in engagement with the lower edge of brack— to be taken as illustrative rather than limitative, since my inventive concept is susceptible of other mechanical et bight wall 15. The spring backing means for sleeve 23 comprises the expressions within the spirit and scope of the subject matter claimed hereinafter. 40 upper leg portion-surrounding coil spring 26 having its upper end engaging the sleeve ?ange 23a and its lower In the drawing, wherein the same reference characters end engaging the previously mentioned leg-carried stop have been used to designate the same parts throughout 25 disposed inwardly of the curled lower end 23b of the FIG. 1 is a longitudinal sectional view of a table sleeve 23 in all operating positions of the latter. The carried bracket and related leg embodying my invention; stop 25 is U-shapcd but with its exterior edge 25a curved FIG. 2 is a sectional view taken on the line 2—2 of FIG. 1; FIG. 3 is a cross sectional view taken on the line 3-—3 of FIG. 2; FIG. 4 is a detail view of a leg carried spring support which is embodied in the invention; and FIG. 5 is a perspective view of the leg carrying bracket. Referring to the drawing by reference characters, nu meral 10 indicates the table top, one of its supporting to slidably support sleeve 23, the leg 11 having opposite sides provided with aligned transverse grooves 24 as shown in FIGS. 1 and 3 to receive the opposed inner edges 25b of the stop member 25. From the foregoing description it will be apparent how the spring actuated sleeve 23 retains leg 11 in the op erative full line position of FIGS. 1 and 2. When the table is to be stored, the respective stop sleeves 23 are legs being indicated at 11 and shown as pivoted, at at 12, pressed downwardly and the related legs are forced in between the side walls 14 of the bracket 13 which is 55 wardly about the pivots 12, the ends 23a of the spring secured to the under table top surface. actuated stop sleeves 23 ride inwardly on the flange edges ‘19, 18 until the respective legs 11 are adjacent the table As illustrated, the bracket is seen to be U-form in horizontal section (FIG. 5) and to comprise the laterally top 10. In this position the pressure of sleeve end 23a spaced side walls 14 which are connected by the bight or against the seat-providing bracket edges 18 retains the rear wall 15. Attachment of bracket 13 to the underside of the table top 10 is made by screws or the like 17 which extend through holes in the outwardly extending top mounting ?anges 16 of the bracket side walls 14. The side bracket walls 14 perform very important func tions as will be explained hereinafter. Referring to FIG. 2, it is noted that bracket side walls 14 have upper frontal edge portions 18 commencing at the site of mounting ?anges 16 and which edge portions constitute a seat for a leg-carried stop when the leg is folded inwardly against the table top. The frontal seat-providing edges 18 are substantially perpendicular to mounting ?anges 16 and extend downwardly for about two-thirds of the depth of leg adjacent the table top 10.
