Improved Hinge with Removable Pin

Inventor: Rudolf Gruber, (Canada) Date of Patent: February 3, 1998 Patent Number: CA 2,228,539 Canadian Patent

A low cost, double shear hinge with a removable hinge pin creates a zero-clearance joint in both axial and radial directions. Bushings are fitted into circular openings in the door side portion of the hinge. A partially internally threaded tube, flanged at the following end, is inserted through the bushings and swaged over the bushing at its leading end. After the body side portion of the hinge with corresponding circular openings is aligned with the door side portion, a hinge pin with a wider threaded following section and a narrower threaded leading section of identical pitch is rotated through the openings to draw the structure together.
