<p>There is a carrier plate, sliding vertically to a case surface via setscrews mounted on two pref. weldable bearing blocks. It has a pressure plate detachably fastened to it solely by clamping screws, and pressed against it with an intermediate strip flap, each block having a parallel offset cutout for the block plate with the setscrew, with a head supported against it, in provision for fastening a door or window hinge strip to a case. The support head (80) has a peripheral groove, with base forming a bearing shaft which passes through the open-edged bearing cutout. Its flanks are separated by a gap corresponding to block plate (36) thickness, and are supportable on the interfacing broad side faces (46,47) of this plate (36). These faces may enclose an acute angle, while the flanks diverge from the base.</p> |
