  • Patent number: 5152594
    Abstract: A base (10) and the method for fabricating the corners (32) of the base (10) of a piece of furniture (12) from tubing (18 ) by notching the tube (18). The notching removes a metal from the tube (18) along the first pair of extremities (40) converging to an apex (44), and along a second pair of transverse extremities (52). Additional material is removed from the space (32) by removing a plug from the tube (18) adjacent the apex (44) in the shape of a bowl having two parallel sides (56), a third side (58) perpendicular thereto and a point (44). The tube (18) is folded at each point (44) creating corners (32) and an enlarged relief space (46) therebetween to allow fluids used in the post-fabrication operations, i.e., washing and painting, to flow quickly therefrom thus increasing drying times. The gussets (52) are welded to the tube (18) to add strength to the base (10).

  • Patent number: 4647241
    Abstract: A modular assembly is provided for use in frame structures which are assembled by joining frame members to connector or fitting members to allow such structures to be easily and quickly assembled and disassembled without the need for a separate assembly tool. In the assembly the frame member telescopically engages the fitting member and both members are constrained from relative rotational and translational movement by a resilient retainer. The retainer has a general spring-like band configuration which includes a backbone portion having two open extending ends. The retainer is flexed over one of the joined members and its backbone engages at least one half of the perimeter of that member. The installed and tensioned length between the two retainer ends is greater than the length between the same ends in a free state, thereby clamping the structural members together. An alignment pin extends radially inwardly from the retainer backbone and engages both members to lock the retainer in place.

  • Patent number: 4641987
    Abstract: A gridwork for a suspended ceiling is assembled by a clip having three equally angularly disposed prongs which run parallel to three equally angularly disposed elongated rigid members of the gridwork. One prong has a stepped configuration, where each level abuts against a portion of two of the three intersecting members. One level of this stepped configuration widens into a lip fitting into a flanged or a "u" shaped channel area of one of the members, and which widened area further snaps into this one member for its securement therein. The remaining two prongs of the clip are bolted to its corresponding elongated member.

  • Patent number: 4636105
    Abstract: Corner pieces for frames are used for joining together frame sides situated adjacent the corner piece. The frame sides are tubular or profile-shaped and adapted in their inner cavity to receive legs which are angularly arranged on the corner piece and interconnected by means of an intermediate part. Each leg consists of two parallel shanks and each shank is shaped so as to be complementary to the cavity of the frame side profile engaging the respective shank so that the shank can be inserted guidingly and with a certain friction in the cavity of the profile. The corner piece is composed of two identical corner parts interconnected by fastening means, the legs and the intermediate part of the corner piece having, on one hand, a first symmetry plane coinciding with the frame plane and, on the other hand, a second symmetry plane or bisector plane bisecting the angle between the legs of the corner piece. The second plane is perpendicular to the first symmetry plane.

  • Patent number: 4630550
    Abstract: A plurality of side rails, cross rails, side and corner legs are prefabricated from a square, tubular, 12 gauge steel material. Separable side and corner connecting members formed of substantially the same tubular steel material include projecting arms and bridging members that are inserted into the open ends of the side rails, cross rails, side and corner members to assemble the table. The connections are secured by bolting the structural frame members to the connecting members. Tubular rectangular side tracks are secured to the upper surface of the side rails in certain installations to provided support for wheeled carriages that are adapted to move longitudinally of the table. The side connectors and corner connectors are, in general, fabricated identically, then utilized in the assembly by slightly different orientation, hole patterns, and the use of the different bridging members.

  • Patent number: 4626124
    Abstract: A structural joint has a pair of elongated members each provided with an elongated groove with an opening narrower than the inside of the groove. A connecting key has a pair of legs configured, in cross-section, like the cross-section of the grooves and slidably fitted each into one of the grooves with side faces of the legs engaging opposed side walls of the grooves. Set screws are threaded through bores of the key legs from the openings of the grooves and up to the bottom of the grooves so that when the screws are tightened, they force the leg side faces into engagement with the side groove opposed side walls to lock the legs into the grooves. The adjacent ends of the legs are articulated to one another.

  • Patent number: 4621879
    Abstract: One corner connecting element (5), in the form of a rail, is present at each corner of a box-like structure having four side walls (3) and one bottom or rear wall (2). With longitudinal grooves (8), the rail engages bent-over edge portions (13) of the walls of the structure. The corner connecting elements (5) are preferably realized in two parts (6,7) in the longitudinal direction, the parts being held together by screws (12). Since the outside of the connecting rail (5) is embodied in the shape of one-quarter of a circle, the corners of the structure are rounded. The fabrication of such structures, such as bathroom cabinets and the like, is simplified as a result, because welded connections can be dispensed with.
