Abstract:
1. A limiting hinge comprising: a stationary bracket; a pintle attached securely to the stationary bracket; a stationary limiting washer mounted securely around the pintle and having an arced limiting flange formed transversely on and protruding from an annular edge of the stationary limiting washer and having two ends; a rotating limiting washer mounted rotatably around the pintle adjacent to the stationary limiting washer and having a rotating bracket mounted rotatably around the pintle adjacent to the second side of the rotating limiting washer and having a positioning washer mounted slidably around and rotated simultaneously with the pintle, disposed adjacent to the second side of the rotating bracket and having a resilient element mounted around the pintle and abutting the positioning washer; and a fastener mounted securely around an end of the pintle, wherein when an external force is exerted to rotate the rotating bracket relative to the stationary bracket, the at least one protrusion is gradually disengaged from the at least one detent, and the rotating limiting washer is rotated simultaneously with the rotating bracket until the limit abuts the limiting flange to disengage the rotating limiting washer from the rotating bracket.
