Claims. (Cl. 311-87) The present invention relates to card tables and refers more particularly to the construction of that part of a table having folding legs concerned with keeping the leg in firmly vertical, supporting position when open and retaining the leg neatly out of the way when folded.

An object of the present invention is to provide a table in which the leg bracing means shall not extend below the level of the table frame or apron.

Another object is that the brace shall have maximum rigidity.

A further object is that the brace shall be adjustable longitudinally.

Another and further object is to provide a table which can be built complete except for the top member, as the top member is frequenly furnished as an article of commerce to the table manufacturer.

Still another object is to provide a table in which the metal fittings constituting pivotal mounts for the legs shall be reinforcements connecting together the frame side members.

In accomplishing the objects of .the present invention, a substantially U or channel shaped bracket is used at each corner of the table, one arm of the bracket being attached to the inside surface of one side member of the frame, and the bight of the U being attached to the inside surface of the adjacent side member. The hinge pin of the leg passes through both arms of the bracket and into the first mentioned side member. A hinge plate is attached to the leg and comprises a knuckle surrounding the hinge pin and a projection substantially at the height of the bottom boundary of the frame side'members.

Approximately midway the length of the side member, an L-shaped bracket is attached to the inside surface of the side member, the free standing portion of this bracket being in the plane of the bottom surface of the top member and thus supporting the latter. A screw engaging the free standing portion from underneath mounts an elongated rigid brace extending therefrom to the hinge plate of the leg and firmly abutting the latter to prevent folding of the leg. The brace is urged downwardly against the projection of the hinge plate by a coil spring, and has freedom for upward pivotal motion against the spring to permit the leg to be folded. Also mounted on the screw in the free standing portion of the L bracket is a leaf spring frictionally engaging the folded leg to maintain the same in folded position.

Alternative brace means are provided in "the form of a spring hinge, one strap thereof being 'aflixed to the under or inside surface of the frame side member and the pin being parallel to the side member. The free strap is urged by the spring into engagement with the projection of the hinge plate of the leg, abutting the same to hold the leg in supporting position.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be exemplified in the constructions hereinafter described. In the accompanying drawings,

2,756,118 Patented July 24, 1956 2 in which are shown two of the various possible illustrative embodiments of this invention:

Figure 1 is a fragmentary vertical section of a corner of the table, on the line 1-1 of Figure 6.

Figure 2 is a fragmentary vertical section of the table through the screw of the L-shaped bracket, on the line 2-2 of Figure 7.

Figure 3 is a fragmentary vertical section of the same corner of the table, on the line 3-3 of Figure 6, but showing the leg in folded position.

Figure 4 is a fragmentary vertical section on. the same plane, also showing the leg folded and retained by the leaf spring of the L shaped bracket.

Figure 5 is a fragmentary section on the Figure 4.

Figure 6 is a fragmentary section on the line 6-6 of Figure 1.

Figure 7 is a fragmentary section on the line 7-7 of Figure 2.

Figure 8 is a fragmentary section corresponding to Figure 1 and showing an alternative brace construction.

Figure 9 is a fragmentary section on the line 9-9 of Figure 8.

Referring now in detail to the drawings, my improved card table 10 has a top member 11. Some manufacturers make card table tops exclusively and an advantage of the present table is that it can be manufactured complete except for the top, which can then be attached as the last step in the manufacture of the table, allowing the table manufacturer greater flexibilityv in the filling of orders for tables specifying various types and finishes of top member 11.

Four side frame members such as 12, 13 are connected line 5-5 of together to form a square frame in which the width of the members 12, 13 is the depth of the frame and the thickness of the members is their horizontal dimension when the table is in use. The top surfaces of the side members are ploughed as illustrated at 14 and 15 for setting top member 11 in flush, and conventional corner construction includes the glued joint 16 and block 17.

A substantially rectangular U or channel shaped bracket 18 is attached to the inside surface of frame side member 13 by the screws 19, 20 and to the inside surface of frame side member 12 by the screws 21, 22, thus connecting the members 12, 13, together-by means independent of and reinforcing the glued joint 16. Screw 19 is driven by a tool inserted through the access hole.

tending past the attached arm of bracket 18- on the side of the hinge plate 27 toward the side member 13.

The L-shaped bracket 35 is mounted by screw 36 and pin 37 with its plate 38 in parallel contact with member 13 and substantially midway the length of member 13,

the plate 39 of bracket 35 being in parallel contact with top member 11 and constituting :a support therefor.

The elongated rigid brace 40 is formed of sheet metal flanged over on both side boundaries. Brace 40 has the longitudinally extending slot 41 formed in its separate but pivotally connected inner end portion 42, thela'tter being mounted on the under surface of plate39 by the screw 43 passing through slot 41 and threaded into plate 39. The leaf spring 44 is also mounted to plate 39, below portion 42, by the screw 43.

Hinge plate 27 'Fhe pivotalioonnection of portion 42 to the major portiqn..of.brace,40.is by means of the ,depending. fingerAS.

integral with portion 42 andextending downwardly for a distance equal to the thickness of the material of the brace, thence outwardly and thence upward-lylthrough the hole 46. Shorter fingers. of portion-42 merely extend downwardly to .provide ansabutting surface "against which the brace may thrust.

Aweak conical. spiral compression spring 48-is located above brace 40. and has itsupoint located-in a hole-49'inthe brace, urging the brace downwardly against the projection29 as inFigures l and 6. A round headed nail 50 is ,driveninto leg 26 frontthe inside surface thereof and its head is engaged by awknee of-leaf-spring-44uas Figure 5 when the leg is folded.

.In operation, the leg 26 is held in vertical, supporting position by the abutmentofbraceAOagainst the plate 27 and urged downward on projection-Baby spring 48. Leg

engages the leg26, each such function serving to maintain the leg in folded position.

Alternative spring actuated abutting brace means forkeeping the. leg 26A in vertical supporting position are illustrated in- Figures 8 and 9.

The U-shaped bracket 18A is fixed to side members 12A and 13A by screws 20A, 21A, 22A and binge pin screw 25A. Hinge plate 27A withfinger 29A integral and projecting therefrom and knuckle 28A integral therewith. is, attached to leg 26 by the screws 31A,32A. The lower portion 27B of plate 27A is substantially vertical in the supporting position of leg 26A and is abutted by the, plate 60 of leafhinge 61, the plate 62 of hinge 61'being screwed to the underside of member 13A by screws 63, 64. A torsion coil spring 65 is part of hinge 61 and causes the same to assume the extended coplanar position of its leaves illustrated inFigure 9. Inthis position of hinge 61- the leg 26A is firmly maintainedvertical by the'abutment as leaf or brace 60against the portion 27B-of hinge plate 27A. Plate 60 may be manually pressed upwardly tothe position shown in dottedlines in Figure 9 to permit folding of the leg. I In this construction the pin and knuckle of thepivot of the brace means, namely hinge 61, is parallel to the leg in folded position,

It will thus be seenthat there is provided a device in which the several objects of this invention are achieved, and which is welladapted .to meet the conditions of p'rac: tical use. As various'possible embodiments. mightbe made of the above invention, and as various changes might be, made in the embodiments above set fortln it is to ,beiunderstood that all matter herein set forth orshown in the accompanying drawing is to be interpretedas illustrative and not in a limiting sense.
