Abstract
An abrasion-enhanced hinge has a pintle, a washer assembly and a stationary leaf. The pintle is connected securely to a cover of an electronic device. The washer assembly has multiple stationary washers and multiple rotating washers. The stationary and rotating washers are mounted interlacedly around the pintle. The stationary washers are connected securely to each other. The rotating washers are connected securely to the pintle. The stationary leaf is connected securely to a base of the electronic device and is connected securely to the nearest stationary washer. When the cover is pivoted to the base, the pintle is rotated relative to the stationary leaf. Thus, the rotating washers are rotated relative to the stationary washers. Because the stationary and rotating washers are mounted interlacedly, the rotations between the stationary and rotating washers provide a lot of abrasions. Therefore, the hinge provides enhanced abrasion.
