Patent ID: 7520540

Claim:
A cover latch comprising a cover body having an inner surface; a proximal edge; and a distal edge; a latch bar being mounted slidably on and parallel to the inner surface of the body near the distal edge of the cover body and having two ends; and two latches being formed on and protruding from the latch bar away from the inner surface of the cover body, each latch being formed at one of the ends of the latch bar; an actuator being mounted rotatably in the distal edge of the body between the two ends of the latch bar; and a driver being connected to the body, the latch bar and the actuator, such that the driver being rotated by the actuator when the actuator is rotated and thereby driving the latch bar to slide, the driver having a shaft connected to the inner surface of the cover body coaxially with the actuator and having a proximal end; a distal end; a leaf formed on and protruding longitudinally from the proximal end of the shaft and connected securely to the inner surface of the cover body; a keyed shaft formed on and protruding longitudinally from the distal end of the shaft; and a flange formed on and protruding radially out from the shaft between the leaf and the keyed shaft; a slide mounted slidably on the keyed shaft, being connected to the latch bar and having a coaxial keyhole formed coaxially through the slide and corresponding to and being mounted slidably on the keyed shaft; an outer surface; a proximal end; and a distal end having two elongated protrusions formed on and protruding longitudinally from the distal end of the slide opposite to each other, each elongated protrusion having two inclined edges; and a flat distal surface; a spring mounted around the keyed shaft between the flange and the slide and pressing the slide toward the distal end of the keyed shaft; and a rotator being mounted on and being rotated by the actuator, engaging and moving the slide along the shaft and having a mounting bracket attached to and rotating with the actuator and having a proximal end attached to the actuator; and a distal end; and a head being attached to and protruding longitudinally from the distal end of the mounting bracket, engaging and pushing the slide against the spring along the keyed shaft and having a distal end having two elongated protrusions formed on and protruding longitudinally from the distal end of the head opposite to each other, each elongated protrusion having two inclined edges, one of the inclined edges on each elongated protrusion on the head engaging and pressing against the corresponding inclined edge on the slide; and a flat distal surface, the flat distal surfaces being the same as the flat distal surfaces on the elongated protrusions on the slide.
