Patent ID: 7578032

Claim:
An angle-limiting hinge comprising: a pivoting leaf having a distal end; a side edge; at least one sleeve being formed on the bottom of the pivoting leaf and having an inner surface; and an engaging protrusion protruding from the side edge of the pivoting leaf adjacent to one of the at least one sleeve; a stationary leaf having a side surface facing the edge of the pivoting leaf; a pintle having a mounting end mounted securely in the stationary leaf; a pivoting portion being mounted tightly through the at least one sleeve of the pivoting leaf, being held by and rubbing against the inner surface of the at least one sleeve to generate a friction; and a limit being C-shaped in cross section, formed radially around the pintle and having two ends being positive stops; and a limiting element being mounted around the pintle and having a through hole being formed through the limiting element, aligning with the at least one sleeve of the pivoting leaf and being mounted around the pintle; a riveted notch being defined through the limiting element, adjacent to and communicating with the through hole; an engaging hole being formed through the limiting element, corresponding to and being mounted securely on the engaging protrusion of the pivoting leaf; and a limiting block being attached securely in the riveted notch of the limiting element and protruding from the limiting element and being disposed between the positive stops of the limit for limiting a rotation between the pivoting leaf and the stationary leaf.
