Their mechanical fastening is done variously – by extruding into wood of door handles by splaying the teeth (8), lateral (12) and rear (13) pins, placing an extra sleeve (16) by making threaded hole for locking bolt (18) through wood trim (1) and metal sleeve (2) compound. In all cases the metal sleeves (2) additionally are glued in the wooden trim. The proposed various means, increase the metal sleeve (2) and trims (1) adhesive strength, such as making in wooden trim (1) a mounting hole (7), different shapes recesses and in outer surface of the metal sleeves (2) introducing grooves (14) by making surface corrugation (15).</p> |
