Attachment of hinge to door or window - involves rib of mushroom cross=section on hinge fitting in groove in door

摘要

The hinged window or door has a frame (1) made from extruded sections (2). The frame (1) has a groove (4) to receive the hinge fixing strip (6) which is secured by screws (12). The part of the hinge (11) which is fixed to the door has a lug (5) with holes for rivets (8) which fasten the rivet to the door. The hinge (11) has a rib (14) with a mushroom shaped cross-section. The rib fits in a matching groove in the extruded section (2). The rib transmits any bending moment, due to the weight of the door, directly to the door frame so that the rivets (8) are not subjected to these bending moments. USE/ADVANTAGE - Door hinge fixing with bending moment transmitted directly to door frame.
