Assembly for fixing e.g. bolts to grille supports - bolt engaging blocks is passed through slot and rotated

摘要

A U section channel (21) has a width slightly less than that of the slots (11) in the grille (10). Across the open end of the U is a collar (23) surmounted by a flange (22). The collar has the same width as the U, a depth (h) equal to the grille thickness and curved portions (23a), (23b) which allow a 90 deg. rotation when fitted in the slot. The flange is wider than the slot and an oval hole allows insertion of a fixing screw. A rectangular metal block (30) is a push fit in the U section, has a length (L") substantially greater than the slot width and has a tapped hole (31) for the fixing screw. Block (30) is inserted into the channel (21) which is inserted in the slot and the flange rotated.
