Abstract
1276068 Clamps BURTON DELINGPOLE & CO Ltd 15 Jan 1971 [14 Feb 1970] 7208/70 Addition to 1202200 Heading E2B A scaffolding coupling for connecting a pair of scaffolding tubes in mutually transverse relationship comprises a central body 9 having a pair of mutually transverse concavedly curved seatings 10 (not shown), and 11 which body is adapted to extend between the tubes, the body being provided with two mutually transverse pairs of lugs 12, 13, 14, 15 with two lugs in each pair disposed at diametrically opposite sides of the central body, one of the two lugs 12, 14 in each pair having hinged thereto, one end portion of a tube embracing clamping jaw 22, 23 having a concavedly curved tube embracing seating, and which one end portion is forked to receive between the arms of the fork, part of the adjacent body lug 12 or 14, and the other lug 13 or 15 of each of the two pairs of lugs being recessed at the side thereof directed away from the jaw that is hinged to the first mentioned lug 12 or 14 of such pair each recess providing a hinge bearing for at least half the depth of the head 17 of a T-shaped bolt 18 but not the whole of the depth of the head, the bolt extends through a hole 19 in the recessed lug and which bolt carries a nut 20 on its free end portion for clamping engagement with the free end portion of the hinged jaw, the central body together with its two pairs of lugs being formed as a forging; the lugs 12, 14 to which the jaws are hinged are each devoid of oppositely extending flanges so as to be of substantially rectangular form in cross-section and the opening movement of each jaw relative to the central body being limited by the free end 28 of each rectangular section jaw hinge engaging with the jaw at a position between the inner ends of the two arms forming the forked end portion of the jaw to which the substantially rectangular section lug is pivotally connected. Each lug of each of the two pairs of lugs adjacent its junction with the central body has an integral reinforcing portion 12a, 13a, 14a, 15a extending from the central body in the direction of the extension thereof of the adjacent lug with the reinforcing portions of the one pair of lugs in each case forming a scaffolding tube engaging extension of that central body seating which, in securing the tube, coacts with that hinge jaw which is associated with the other pair of the two pairs of lugs. The lugs 12a and 14a have an outer corner of right angle configuration in crosssection to provide a sharp edge 12b, 14b, curved about the axis of curvature of the adjacent seating so that it can bite into the scaffolding tube and in the case of a vertical tube prevent the coupling slipping down the tube when under load. The mass of each of the bolt hinging lugs 13, 15 is substantially that of each diametrically opposed jaw hinging lug 12, 14 respectively by eliminating the metal of the jaw shown at 13c in Figure 1.
