Patent ID: 8020254

Claim:
A hinge assembly comprising a pintle having two ends; and a shaft being non-circular in cross section, being formed on one end of the pintle and having a distal end; a rotating bracket being mounted rotatably around the shaft and having an inner surface; an outer surface; a proximal end being mounted rotatably around the shaft; a distal end; and a latching portion being formed on the distal end of the rotating bracket; a sliding bracket being attached securely to the pintle and having a mounting protrusion; and a track being attached to the mounting protrusion; a mounting bracket being slidably mounted around the track and having two ends; at least one recess being formed in the mounting bracket and accommodating the track; and a latching arm being formed on one end of the mounting bracket, protruding transversely from the mounting bracket and selectively retaining the latching portion; a compression assembly being mounted around the shaft adjacent to the rotating bracket and having a moving member being mounted rotatably around the shaft, being attached securely to the rotating bracket and having an inner surface facing the rotating bracket; an outer surface; two moving positioning blocks being formed opposite each other on the outer surface of the moving member and each moving positioning block having a limiting surface being perpendicular to the outer surface of the moving member; and a slope extending from the limiting surface and converging to the outer surface of the moving member; and a stationary member being slidably mounted around the shaft adjacent to the moving member and having an inner surface abutting the moving member; an outer surface; and two stationary positioning blocks being formed opposite on the inner surface of the stationary member and each stationary positioning block having a limiting surface being perpendicular to the inner surface of the stationary member; and a slope extending from the limiting surface and converging to the inner surface of the stationary member; and a washer assembly having an elastic member being mounted around the shaft adjacent to the stationary member of the compression assembly; and a fastener being mounted securely on the distal end of the shaft.
