<p>1,229,450. Clips. WARREN FASTENER CORP. 21 Aug., 1968 [22 Aug., 1967], No. 39956/68. Heading E2B. A cable or pipe clip formed from resilient sheet material, comprising a bowed supportengaging portion 30, with a reversely rounded foot portion 32, 34 at each end, at one of which the material of the clip is bent back to overlie the bowed portion and provide a cableengaging portion 48 beneath which a cable or pipe can be gripped, and the clip being such that with the foot portions in engagement with a support and with pressure applied to the bowed portion tending to flatten it, the clip can be caused to slide under retaining means provided on the support so that on said pressure being released to allow part of the bowed portion midway, or substantially so, between the foot portions to bear against the retaining means, the clip will be gripped under the influence of its own resilience between the retaining means and the support. In the construction shown in Fig. 1 the retaining means are the flat heads 27 of three buttons 24, 26, 28 the shank of each of which is welded to the support; the portion of the clip has three keyhole slots 36, 38, 40 for engaging the buttons and the centre slot for engaging the button 28 has a neck formed by shoulders 42 so that once the shank of the stud has passed the shoulders it is retained in the narrow part of the slot. The walls of the slot 40 are made resilient so that the shank of the stud 28 can pass the neck by slots 46. In a modification instead of the retaining means being buttons, the retaining means is a bridge piece welded to the support the portion 30 passing under the bridge piece; tongues are punched and bent from the arcuate portion and engage the opposite sides of the bridge piece to hold the clip in place. In this construction the arm holds the cable or tube in engagement with the bridge piece.</p> |
