Abstract
A hinge has a stationary leaf, multiple resilient flat washers and a pintle. The stationary leaf has a sleeve. The resilient flat washers are mounted in the sleeve and each resilient flat washer has a ring and a key wing. The ring has a receiving recess formed in a first surface and a mounting rib formed in a second surface. The receiving recess of each resilient flat washer engages the mounting rib of a corresponding resilient flat washer. With the engagements of the receiving recesses and the mounting ribs, the resilient flat washers are connected to each other to enhance the strength of the resilient flat washers. Therefore, the resilient flat washers are strong enough to bear the abrasion for long term use.
