A detent element (14) is embodied on the securing element (11) and elastically engages in detent fashion in a detent seat (13) embodied on a wiper bearing (15) of the wiper device (10).
Abstract: The fastener includes a post element, a blind aperture assembly with a blind aperture into which the post element is inserted, and a rigid fastening member. The rigid fastening member includes a lower helical edge with an inwardly extending lip which threadably engages the external threads formed on the post. The inclined rotationally symmetric wall deflects upon insertion into the blind aperture, but then interferes with the walls of the blind aperture to resist withdrawal.
Abstract: A beam clamp retaining strap has a beveled locking slot for securing to a threaded hanger rod or set screw of a pipe support assembly mounted to an I-beam. The assembly further comprises a C-type clamp, and the strap may be positioned in any of four possible locations with respect to the clamp, rod, and set screw. The slot edges securely engage between the major and minor thread diameters of the rod or screw. The beveled locking slot provides additional assurance that the clamp grip does not loosen such that the pipe assembly is dislodged, and, thus, the need for an additional nut for the retaining strap is thereby eliminated.
