1466141 Vehicle sun roofs TELEFLEX Inc 7 May 1974 [11 May 1973] 20132/74 Heading B7B [Also in Divisions E2 and F2] A push-pull core 12 formed from a number of individual wire strands helically wound together on a long lead and having a helically coiled wire 14 disposed about the core 12 in spaced convolutions, includes a terminal means 16 of organic polymeric or plastics material moulded to encase the coiled wire 14 and the core 12 in the areas between adjacent convolutions of the coiled wire 14. As shown in Figs. 1 to 3 a vertically slidable window 20 is operated by gear-wheels (not shown) which engage, in the manner of a rack, the helically wound wire of each of a pair of such cores 12 movable in spaced guides 26, the plastics ends 16 providing low friction bearings in the guides 27 and having moulded extensions 18 thereon by which the cable core ends 16 are secured at 22 to the window and which slide, together with the window 20, in extensions 30 on the guides 26. Figs. 5 and 6 illustrate a typical Bowden cable assembly 110 in which the end of the core 112, 114 is encased at 116 in the above described manner, the moulded plastics material 116 having an outside diameter corresponding to the outside diameter of the convolutions 114 whereby the core 112, 114 and plastics end 116 readily slide in a conduit 126, Figs. 7 to 9 (not shown), illustrate an arrangement, similar to the window operating assembly of Figs. 1 to 3 described above, for operating a sliding sun roof unit for a motorvehicle. |
