Patent

CA 2670352

A casement window hinge eliminates the use of rivets in the pivot between the sash arm and guide arm such as require a high force deformation of an element to a precise compression that varies according to a "tolerance stack up" between four controlled dimensions of the parts being assembled: the length of the rivet, the deformation of the rivet head, and the thickness of the two arms being assembled. The invention eliminates two of these dimensions through the use of integrally molded pivot pins that fit into a bore in the second arm and which are plastically flanged. Resistance to a pull-out of wood screws that are countersunk into a plastic sash arm is provided by exaggerated counter sinking with undersized countersink bores.
