Patent ID: 7513014

Claim:
A hinge assembly comprising: a tubular stationary leaf, a cylindrical pintle, and a pivoting leaf, wherein the tubular stationary leaf has a stationary sleeve and a mounting segment, and the stationary sleeve comprises: an inner end; an outer end; an outside surface; a gudgeon formed coaxially through the stationary sleeve as cylindrical hole; a slit formed longitudinally through the outside surface of the stationary sleeve from end to end and communicating with the gudgeon; a limiting tab having two sides and being formed on and protruding longitudinally from the stationary sleeve; and at least one braking detent formed on and protruding from the stationary sleeve near the limiting tab, wherein the mounting segment is formed on and extends from the outside surface of the stationary sleeve, wherein the pintle is tightly mounted rotatably in the gudgeon extending out of the stationary leaf and comprises: an inner end tightly mounted rotatably in the gudgeon of the sleeve of the stationary leaf; an outer end; a limit mount formed transversely through the pintle and corresponding to the limiting tab and the braking detent; and a limiting rod mounted securely in the limit mount of the pintle and having two ends diametrically extending transversely out of the pintle, each end of the limiting rod selectively abutting respectively the sides of the limiting tab, and one end of the limiting rod selectively abutting the braking detent, wherein the pivoting leaf is mounted securely on the outer end of the pintle and comprises: a pivot sleeve mounted securely on the outer end of the pintle and having an outside surface; and a pivoting leaf mounting segment formed on and extending from the outside surface of the pivoting leaf.
