Abstract

1343199 Wall plugs A FISCHER 29 June 1971 [8 Aug 1970 3 Sept 1970] 30407/71 Heading F2H A wall plug for use in a wall of soft or porous material comprises a generally cylindrical expansible sleeve 2, having leg portions defined by longitudinal slots 3 extending from one end, and a generally cylindrical expander 4 with the same number of triangular laminar wings 6 as there are leg portions of the sleeve, so that each leg portion is expanded outwardly by a respective wing 6 when the expander 4 is drawn into the sleeve 2. The slots 3 have transverse slots 11 at their inner ends to facilitate spreading apart of the leg portions. In Fig. 1, the expander 4 forms the head of a bolt 5. In Figs. 3, 4 (not shown) the expander is a nut held captive in the sleeve by inturned flanges at the tips of the leg portions. The wings project through recesses 14 in the leg portions. In Fig. 5, the sleeve 2 comprises two sheet metal pressings 15, 16 which when laid together form longitudinal ribs 17, 18, the pressings being spot-welded together at 19. The expander comprises an internally screw-threaded cylindrical core 4 round which are secured sheet-metal pressings 20, 21 forming the wings 6. To install a wall plug, a hole is drilled in the wall whose diameter corresponds to the outer diameter of the sleeve 2. The plug is then driven into this hole, the wings 6 (and the ribs 17, 18 in Fig. 5) penetrating the wall material surrounding the hole. Finally the expander 4 is drawn into the sleeve to bend the leg portions outwardly into the material surrounding the hole, as in the lower half of Fig. 1.
