Abstract: The invention provides a device for coupling together two elements, each of predetermined shape, so that the two elements are prevented from rotating relative to the device. The device is constituted by a band, which is substantially rigid and is in the form of a closed loop. The band has two rims which are three-dimensionally out of true, and each rim delimiting an opening, which forms the limit of a recess, in which one of the elements to be coupled together can be positioned. The regions of each of the two recesses which lie opposite the openings form part of a single space which is laterally delimited by the band. Each rim substantially constitutes a curve traced on a convex surface of the element of predetermined shape to be coupled.The invention also provides a method of making a coupling device.

Abstract: A coupler (for joining tubing to a shoring leg or the like, having a T-shaped bolt slot extending along the length of such leg) is formed of a sickle-shaped metal strap or extrusion, having a C-shaped central portion, a radial extension portion at one end, and a tangential T-portion at the other end, said T-portion being formed of a head and a relatively narrow neck with adjacent opposing shoulders; and a T-bolt secured through a hole in the extension portion. The head and shoulders defining the neck of the T-portion are spaced and shaped so as readily to accommodate therebetween the lips forming the T-slot when the T-portion is inserted generally perpendicularly into the T-slot and yet grippingly bite into said lips when the coupler falls into the cocked open position. This permits the coupler provisionally to cradle and hold the tubing in place before the T-bolt is fastened.

Abstract: To facilitate manufacture of lightweight bicycle carriers, in particular the attachment of supporting struts (6, 7) to a frame (1) having longitudinal support rods (3) for example formed of aluminum, the longitudinal support rods have injection-molded attachment elements (12) molded thereof, made of resiliently expandable material, with an open slit (18) extending to an opening (17) therein, permitting cross elements (10, 11) of the support struts (6, 7) to be snapped therein, the projecting portions (15) then being held closed by outer clamping or holding rings (19) slipped over the projecting portion and securing the cross elements (10, 11) of the support struts in irremovable position on the holding elements.

Abstract: An improved cross-arm brace for supporting a cross-arm (24) on a utility support pole (23) is described. The brace has two support members (10) which lie along the support pole (23), one on each side of the support pole (23), and between the support pole (23) and the cross-arm (24). The support members (10) are connected to each other by one or more connecting members (11) which cross the pole (23) over that face of the pole (23) on which lies the cross-arm (24). Adjusting mechanisms (12, 14, 15, 16) associated with the connecting members (11) adjust to decrease the spacing between the support members (10) and thus to firmly wedge the support members (10) between the support pole (23) and the cross-arm (24). More than one cross-arm (24) on a support pole (23) can be supported by a single brace. The brace can be used in conjunction with a grid gain.
