There is shown in FIG. 1 of the drawings a table generally designated by the numeral Ztl including a table top 22 and four legs 24, 26, 2? and 30 which are connected to the table top 22 by means of bracket assemblies generally designated by the numeral 32 and made in accordance with and embodying the principles of the present invention. The table top 22 is a planar support member having an upper flat surface and a lower fiat surface 34 (see FIG. 2) on which are mounted the bracket assemblies 32. Each of the bracket assemblies 32 includes a pair of brackets 36 and 33, a carriage bolt 37 and a wing nut 39.

The brackets 36 and 353 are mirror images one of the other and are preferably formed of sheet metal by stamping and bending operations. The bracket 36 includes a side plate ll) having an upper edge 52 and a side edge 44, the upper edge 42 having a top flange 46 formed integral therewith by means of a bendable connection and extending substantially perpendicular thereto and the side edge -1-4 has a side flange 43 formed integral therewith and disposed substantially perpendicular to the side plate 44 and extending in a direction opposite to the top flange 46. The side plate lli, the top flange 46 and the side flange 4B are disposed in mutually perpendicular planes with the edges 42 and 44 disposed perpendicular to each other. The top flange &6 has a plurality of openings, for example three, therein to receive screws 50 for mounting the bracket 36 upon the undersurface 34 of the table top 22 and the side flange 48 has a pair of spaced apart apertures 52 therein which may be utilized to receive screws therethrough more securely to connect an associated leg to the bracket 36, as will be explained more fully hereinafter. The side plate as is formed generally square in shape and has a lower rounded corner 5d disposed away from the flanges 46 and 48 and is provided with two square holes 56 and 58 therein, the hole 56 being disposed from the top edge 52 a distance equal to the distance to the nearest point of the side flange 48; the hole 58 is similarly disposed a distance from the top edge 42 equal to the dis tance to the side flange 48.

The bracket 38 includes a side plate as having a top edge 62 and a side edge 64, the upper edge 62 being formed integral with a top flange 66 which is disposed perpendicular to the side plate as and is connected thereto by a bendable connection to permit flexing between the side plate 6% and the top flange 66. The side edge 64 has a side flange 63 formed thereon and disposed substantially perpendicular to the side plate 60 and extending therefrom in a direction opposite to the top flange as. More specifically, the side plate 69, the top flange 66 and the side flange 68 are disposed in mutually perpendicular planes and the edges 62 and 64 are disposed perpendicular to each other. The top flange 66 has a plurality of openings 76 therein, three of the openings 70 having been shown for purposes of illustration, to receive therethrough screws 50 to mount the bracket 38 upon the undersurface 34 of the table top 22. The side flange 68 is provided with two apertures 72 therein to receive fasteners therethrough more firmly to mount the associated leg upon the bracket 38, as will be explained more fully hereinafter. The side plate 69 is generally square in shape and has a rounded corner 74. Two square holes 76 and 78 are provided in the side plate 60, the hole 76 being positioned equidistant from the top edge 62 and the side flange 68 and the hole 78 likewise being positioned equidistant from the top edge 62 and the side flange 6?. There also is provided a pair of apertures 80 in the side plate 63 to receive fasteners more firmly to mount an associated leg under certain conditions as will be more fully described hereinafter.

in assembling the brackets 36 and 38 upon the table top 22, the side plates 44} and 60, respectively, are disposed parallel to each other and the facing surfaces thereof are spaced apart a distance equal to the width of the associated leg such as the leg 24 in FIGS. 2, 3 and 4. The top flanges 46 and 66 are disposed against the undersurface 34 of the table top 22 and the side flanges 43 and 63 are disposedpo that the surfaces thereof lie in the same planes. After the brackets 36 and 33 are thus positioned, the screws 50 are inserted through the openings in the top flanges 46 and as firmly and rigidly to secure the brackets 36 and 33 to the table top 22.

When assembling a leg 24 having the larger dimensions to the table top 22 by means of the bracket assembly 32, the carriage bolt 37 is inserted through the aligned set of holes 58 and 78 in the brackets 36 and 38, respectively. Referring more particularly to FIG. 6 of the drawings, it will be seen that the carriage bolt 37 includes a head 82 which has formed adjacent thereto a square shank portion 84 adapted to be disposed in one of the square holes 55, 58, 76 or 78, and formed integral with the square shank portion 84 is the usual cylindrical shank portion 86 terminating in a threaded portion 88 adapted to extend through one of the aligned holes and to receive on the outer end thereof the wing nut 39. In one preferred form of the invention, the distance between the adjacent edges of the holes 58 and 78 and the associated top edges and the side flanges is 1% inch to receive a leg 24 having a thickness of 1% inch and a width, for example of 3 /2 inches. When such a leg 24 is assembled with the brackets 36 and 38 as illustrated in FIG. 6 of the drawings, the bolt 37 disposed in the openings 58 and '78 will urge the leg 24 against the side flanges 48 and 68. By tightening the wing nut 39 against the side plate 64?, the head 82 of the bolt 37 is pressed against the side plate it} and the side plates 40 and 60 by virtue of the bendable connections thereof with the top flanges 46 and 66, respectively, can be firmly urged against the sides of the leg 24, whereby firmly to clamp the leg 24 with respect to the brackets 36 and 38 in the position illustrated in FIG. 3. It has been found that by means of the improved bracket assembly 32 of the present invention, the leg 24 can be held in this position without the use of any additional fasteners interconnecting the brackets 36 and 38 and the leg 24. It further has been found that the leg 24 need not have the upper end 90 thereof disposed against the undersurface 34 of the table top 22 and that the leg 24 can be held in any adjusted position such as is illustrated by dashed lines in FIG. 3 whereby the leg 24 can be used to level the table top 22, the brackets 36 and 38 being urged into firm clamping engagement with the sides of the leg 24 by means of the carriage bolt 37 and the cooperating wing nut 39.

The leg 24 can be quickly and readily disassembled from the bracket assembly 32 by simply loosening the wing nut 39, whereupon the leg 24 can be bodily dropped from the bracket assembly 32. It is also convenient to store the leg 24 in a condition flat against the undersurface 34 of the table top 22 and to this end the leg 24 can be positioned as illustrated in FIG. 4 of the drawings with the upper end 39 disposed against the side flanges 48 and 68, the parts being held in this position by tightening the Wing nut 39 upon the carria e bolt 37 thereby firmly to clamp the side plates at and 60 against the side surfaces of the leg 24.

In those cases in which it is desired more securely to mount the table top leg 24 with respect to the brackets 36 and 38, suitable fasteners such as wood screws can be inserted through the apertures 52, 72 and thereby positively to mount the leg 24 with respect to the brackets 36 and 38.

There is illustrated in FIGS. 7 through 9 of the drawings the manner in which the bracket assembly 32 of the present invention can be used conveniently to mount a leg 124 upon the table top 22, the leg 124 having a smaller thickness dimension than the leg 24 and having a thickness of only 1 /8 inch. When mounting the leg 124 using the bracket assembly 32, the carriage bolt 37 is disposed in the holes 5t? and 76 so that the edge of the carriage bolt 37 disposed toward the side fianges 48 and 68 is spaced therefrom a distance substantially equal to the thickness of the leg 124 whereby the carriage bolt 37 serves to position the leg 124 against the side flanges 48 and 68. By tightening the wing nut 39 upon the carriage bolt 37, the side plates 40 and 60 can be urged into clamping engagement with the contacting surfaces of the leg 12 4 thereby to mount the leg 124 in a supporting position as illustrated in 7 of the drawings. he upper end 193 of the leg 124 can also be spaced from the undersurface 34 of the table top 122 whereby the leg 124 may be used to achieve leveling of the completed table 29.

The leg 124 can also be held in a non-supporting or stored position as illustrated in FIG. 8 wherein the leg 124 is disposed against the undersurface 34 of the table top 22 and is clamped in this position by tightening of the Wing nut 39 upon the carriage bolt 37 thereby to urge the side plates 44) and 66) into clamping engagement with the adjacent surfaces of the leg 124.

It will be seen that there has been provided an improved bracket assembly which fulfills all the objects and advantages of the present invention. More specifically, an improved bracket assembly has been provided which can securely clamp an associated leg in a supporting position or in a folded non-supporting position, the leg in the supporting position being adjustable with respect to the associated table top to provide a leveling action. No bolt holes are required in the leg, yet a firm clamping of the leg in the adjusted position is achieved. If desired, a more permanent mounting of the leg on the associated brackets can be obtained by placing fasteners through the apertures provided in the side plates and in the side flanges.
