Patent ID: 7685680

Claim:
A rotatable slide hinge comprising: a stationary leaf having an arced edge; a slot having a default limit, a pivotal limit and a lip formed around and protruding into the slot; a guide channel being parallel to the slot, and having a default limit, a pivotal point and a lip formed around and protruding into the guide channel; an arced channel extending from and communicating with the pivotal point of the guide channel and corresponding to the arced edge of the stationary leaf ( 10 ), wherein the arced channel is formed around the pivotal limit; and a stationary spring hole formed in the stationary leaf; a moving leaf mounted on a bottom of the stationary leaf, sliding and turning relative to the stationary leaf and having a guide edge corresponding to the arced edge of the stationary leaf; a pivot pin hole formed in a top surface of the moving leaf and connected to the slot of the stationary leaf via a pivot pin, wherein the pivot pin is provided with a pivot pin washer to clamp the lip of stationary leaf; a guide pin hole formed in the top surface of the moving leaf and connected to guide channel of the stationary leaf via a guide pin, wherein the guide pin is provided with a pivot pin washer to clamp the lip of the stationary leaf; and a directing pin hole formed in the top surface of the moving leaf; a spring attached to the stationary leaf and having a stationary end connected to the stationary spring hole of the stationary leaf; and a moving end connected to the guide pin hole of the moving leaf through the guide channel of the stationary leaf via the guide pin; and a directing assembly corresponding to the arced edge of the stationary leaf, mounted on the moving leaf to guide the moving leaf slidably along the arced edge and having a directing washer mounted between the arced edge of the stationary leaf and the moving leaf; and a directing pin abutting the arced edge of the stationary leaf, extending through the directing washer and mounted securely in the directing pin hole of the moving leaf; wherein the spring forces the moving leaf to move relative to the stationary leaf for a predetermined distance, and then the moving leaf rotates about the pivot pin until the guide pin abuts against the an end of the arced channel of the stationary leaf.
