US Patent 8245356 Hinge with spacers

A hinge has a pintle, a spacer assembly, a stationary bracket and a rotating bracket. The pintle is mounted through the spacer assembly and is connected to the stationary and rotating brackets. The spacer assembly has multiple spacers stacked with each other. Each spacer has a ring segment and a bearing segment. The ring segment is mounted around the pintle. The bearing segment has an absorbing space to absorb the stress acting on the ring segment. Therefore, the spacer sustains less stress to prevent breakage easily and a lifespan of the spacer is extended. Therefore, the hinge has a longer lifespan.
