Abstract
1481801 Tube couplings RYDERS (LANCASHIRE) Ltd 17 July 1974 [17 July 1973] 33904/73 Headings F2G and F2M Two tubes 22, 23 are coupled by a coupling member comprising two cylinders 19 of for example aluminium interconnected by screw - threaded stud 21 extending through disc 20 and screwed into screwthreaded bores in respective cylinders 19. Each cylinder 19 has at its free end a resilient element 15 e.g. of rubber which has a slightly larger diameter than that of cylinder 19, a steel washer 16 whose diameter equals that of cylinder 19 and a bolt 17 which passes through washer 16 and element 15 and screws loosely into the bore of cylinder 19. Element 15 has a centre hole of diameter less than that of the shank of bolt 17 so that element 15 frictionally grips bolt 17. Tubes 22, 23 are coupled by fitting one on to each end of the coupling member until they abut disc 20 and then rotating tube 23 clockwise with respect to tube 22, as viewed in the direction of arrow B, which as a result of the frictional engagement between tubes 22, 23 and elements 15, and between elements 15 and bolts 17 rotates tube 23 and thus bolts 17 are screwed into cylinders 19 axially compressing elements 15 between washer 16 and the end of cylinder 19 causing the elements 15 to expand radially outwards to grip tubes 22, 23 and hold them against axial movement relative to the coupling. The tubes are released by relative rotation in the opposite direction. In another embodiment a tube is coupled to a plate by a coupling member having a single cylinder bolted to the plate at one end and having a resilient element and washer bolted loosely to the other end, the tube being pushed on to the coupling member and rotated thus screwing the bolt carrying the washer and the resilient element into the cylinder and axially compressing the resilient element causing it to expand radially against the inner surface of the tube preventing axial movement of the tube relative to the coupling. The couplings may be used in the construction of hand rails.
