Abstract

1435298 Expansible fasteners HARRIS & EDGAR Ltd 12 June 1973 [21 March 1972 18 July 1972] 13218/72 and 33494/72 Heading F2H An expansible fastener comprises a tube 4 formed by bending a piece of flat material and with at least one slot 4b extending along the tube, and two members 3, 5 one, or both (as shown) of which are annular provided with camming surfaces and arranged to engage opposite ends of the tube 4 so that on being drawn towards each other the members expand the tube. The tube 4 may be externally roughened and provided with slits 4c or apertures and the annular members 3, 5 may be provided with projections 3a, 5a for engagement with the slot, slits or apertures of the tube. At least one of the members 3, 5 is internally threaded for engagement with an externally threaded member which may be a headed bolt 1 or a stud (Fig. 2, not shown). The member, 5, may be integral with a threaded rod or stud (not shown). Wedging members 206, 206a may be provided between the tube and annular members to assist in the expansion of the tube. The tube may have apertures 104 in lieu of the slits. Portions 205a may extend from the member 205 to engage in apertures 104e in the tube. Truncated conical sleeves (106) may fit over the camming portions of the members for added expansive effect, Fig. 1 of Specification 1,435,298 (not shown). Alternatively, the tube may be formed with end beadings or thickened by bent back integral tabs.
