Filed Feb. '7, 1964 United States Patent F 3,281,104 CORNER CONSTRUCTION Earl F. Hamilton, Columbus, Ind., assiguor to Hamilton Cosco, Inc., Columbus, Ind., a corporation of Indiana Filed Feb. 7, 1964, Ser. No. 343,337 10 Claims. (Cl. 248-488) This invention relates to a corner construction, and more particularly to a corner construction for interconnecting a shelf to a supporting leg.
It is an object of the invention to provide a corner construction for interconnecting a shelf to a supporting leg which will not detract from the appearance of the article employing such construction, which can be quickly and easily assembled, and which will prove sturdy and durable muse.
This invention is concerned with the interconnection of a tubular leg to a shelf having a supporting surface provided with a depending border skirt. The supporting surface and skirt of said shelf have a cut-out portion at the corner of the shelf disposed in abutting engagement with a pair of adjacent sides ofthe leg. A generally triangularly shaped channeled brace having a web interconnecting a pair of arms is carried under said shelf with said pair of arms abutting the adjacent faces of the supporting surface and bead. Fastening means are provided with portions received in openings formed in the leg and the web of the brace for interconnecting said brace and thus the shelf to the leg. The brace web extends diagonally across the corner of the shelf and the portions of said fastening means received in the leg and web openings are angularly offset with respect to each other whereby said fastening means will bear against the web for bindingly retaining the edges of the brace arms against the shelf skirt to rigidly interconnect said shelf and leg.
Other objects and features of the invention will become apparent from the more detailed description which follows and from the accompanying drawings, in which:
FIG. 1 is a plan view of a corner construction embodying the invention with portions thereof being broken away;
FIG. 2 is a vertical section on an enlarged scale taken on the line 2-2 of FIG. 1;
FIG. 3 is a vertical section on an enlarged scale taken on the line 3-3 of FIG. 1;
FIG. 4 is a plan view of a modified form of the corner construction shown in FIG. 1 with portions thereof being broken away;
FIG. 5 is a vertical section taken on the line 5-5 of FIG. 4;
FIG. 6 is a vertical section taken on the line 6--6 of FIG. 4; and
FIG. 7 is a perspective view of the brace shown in FIGS. 1 and 4.
As shown in FIG. 1, a tubular leg 10 is interconnected to the corner of a shelf 12 lying in a plane generally normal to said leg and comprising a supporting surface 14 provided with a depending border skirt 16 terminating in an inwardly rolled bead 17. The supporting surface 14 and skirt 16 have a cut-out portion, as at 18, at the corner of the shelf. The cut-out portion 18 provides a mounting seat for the leg 10 with the ends of said skirt and supporting surface abutting a pair of adjacent sides of the leg 10.
A brace 20 is carried on the underside of the shelf 12 and comprises a web 22 interconnecting upper and lower arms 24 and 25. The arms 24 and 25 have a generally triangular shaped configuration and are provided with cutout portions 26 remote from the web 22 which abut a pair of adjacent faces on the leg 10. As shown in FIG. 3, the arm 24 abuts the lower face of the supporting surface 14 in face to face contact, and the edges of the arm 25 abut the upper face of the head 17 in face to face contact.
3,281,104 Patented Oct. 25, 1966 ICC Desirably, the edges of the arms 24 and 25 are bent downwardly, as at 27 and 28, with the edges 27 abutting the inner face of the skirt 16 and the edges 28 being received between the bead 17 and the skirt 16.
A channeled bracket 30 having a web 32 interconnecting a pair of parallel arms 34 extends under the shelf along one side thereof. The web 32 projects 'beyond one end of the arms 34 and has its end remote from said arms hooked, as at 36, for locking reception in an opening 38 formed in the leg 10. Intermediate its ends, the bracket 30 is curved, as at 40, and an opening 41 is formed in the web 32 within the extent of the curved portion 40. Said opening 41 receives the shank of a bolt 42 projecting through an elongated slot 44 formed in the brace web 22. The bolt 42 is interconnected to the brace 20 and bracket 30 by a nut 45 disposed Within the extent of the arms 34 and abutting the adjacent faces of said arms in face to face contact to prevent rotation of said nut upon tighten ing of the bolt. With the web 22 extending diagonally across the corner of the shelf 12 and the bracket 30 being offset at 40, the axis of the bolt 42 will be normal to the plane of the web 22 so that upon tightening of the bolt within the nut 45 the brace arms 24 and 25 will be bindingly retained against the shelf skirt 16 on opposite sides of the leg 10 for thus rigidly interconnecting said shelf to the leg. Tightening of the bolt further causes the brace web to be drawn against the bracket web 32 to cause the arms 34 to bear against the skirt 16.
A modified form of the corner construction is shown in FIG. 4. In this embodiment, the leg 10 is interconnected to a shelf 12 comprising a supporting surface 14' and a peripheral border skirt 16' terminating in an inwardly rolled bead 17'. The skirt 16 and supporting surface 14' are cut-out at the corner of the shelf, as at 18, to form a mounting seat for the leg 10 with the edges of said skirt and bead abutting a pair of adjacent faces on said leg.
The brace 20 is carried against the underside of the shelf 12' with its arms 24 and 25 abutting the adjacent faces of the supporting surface 14' and bead 17'. The downwardly extending edges 27 of the arm 24 abut the inner face of the skirt 16' and the downwardly extending edges 28 of the arm 25 are interposed between the skirt 16' and bead 17. The cut-out portions 26 of said arms abut the same adjacent faces of the leg 10' as the edges of the cut-out portion 18.
The brace 20, and thus the shelf 12', is interconnected to the leg 10 by a stud 46 having one of its ends flattened, as at 48, and provided with a hook 50 lockingly received in an opening 52 formed in the leg 10'. The opposite end of said stud is threaded and projects through the slot 44 in the brace web 22 for reception of a nut 54 adapted to be drawn up against the brace web 22 to cause the ends of said web and the edges of the arms 24 and 25 to be bindingly retained against the shelf skirt 16 on opposite sides of the leg 10'. As shown, the Web 22 extends diagonally across the corner of the shelf 12, and the ends of the stud 46 are angularly offset with respect to each other so that the threaded portion of said stud lies on an axis normal to the plane of the web 22. Desirably, a spacer 56 is formed on the stud 46 intermediate its hooked and threaded ends. Said spacer abuts the adjacent faces of the arms 24 and 25 in face to face contact to prevent rotation of the stud 46 with respect to the brace 20 as the nut 54 is drawn up on said stud.
While the invention has been illustrated as an interconnection between a shelf and a leg having a rectangular cross-section, it is to be understood, of course, that said leg may have any desired cross-sectional configuration.
