Abstract

A family of reversible hinges includes a strap hinge, a tee-hinge and a screw hook hinge. Each of the strap hinge, tee-hinge and screw hinge includes a universal strap leaf, a secondary strap leaf, a removable hinge pin and at least one bearing. The universal strap leaf is interchangeable between each of the strap hinge, the tee-hinge and the screw hook hinge, creating commonality amongst the family of reversible hinges, thereby reducing tooling costs and inventory levels associated with the family of reversible hinges. Further, the at least one bearing is manufactured from an acetal material to reduce hinge noise and prevent rust-lock.
