Abstract
1337688 Screw sockets L A MORTENSEN 21 March 1972 [22 March 1971] 13138/72 Addition to 1289276 Heading F2H An expansible socket for anchoring a screw 11 in a hole through a panel 22 or in a wall comprises a deformable tubular anchoring member 13 of plastics, e.g. a polyamide, having at one end an internal shoulder 29 and a portion 24 to engage the thread of the screw 11 so that the member 13 can be expanded radially by compressing it axially, and axial or helical slits or slots 15 along the wall of the anchoring member 13, and an expansion member 51 within the anchoring member 13 between the shoulder 29 and one end of a tubular element 21 or 12 so that the expansion member 51 is driven into the adjacent end of the element 21 or 12 to expand it radially as the anchoring member is compressed axially. The expansion member 51 may be chamfered at one or both ends, its outer surface may be cylindrical or part-spherical, and it may be integral with the shoulder 29. The portion 24 is a metal, glass-fibre reinforced plastics, or polyvinylene oxide nut to which the anchoring member 13 is moulded. The tubular element 21, of a polyamide or polyethylene, may have axial or helical slits near its inner end to form an easily expansible portion. In Fig. 4, a P.V.C. sleeve 12 lies between the expansion member 51 and a stiff tubular element 21, and is the member expanded radially.
