Patent ID: 7987555

Claim:
A hinged slide rail, comprising at least: a rail, which comprises at least a fixed plate, a balled plate, and a movable plate, the balled plate being interposed between the movable plate and the fixed plate to allow the movable plate to do reciprocal sliding movement with respect to the fixed plate; a hinge, which is mounted to a surface of the movable plate, the hinge comprising a movable blade and a fixed blade that are rotatably coupled to each other so that the movable blade is reciprocally rotatable with respect to the fixed blade, the fixed blade being fixed to an end of the movable plate, the movable blade having an end to which a pull bar is mounted; a retention frame, which is mounted to the fixed blade and defines therein an accommodation space, the retention frame having an end forming two limiting slots; a buffering device, which is received in the accommodation space of the retention frame, the buffering device comprising an active rod having an end forming a limiting block that is slidably received in the two limiting slots, the limiting block being coupled to the pull bar of the movable blade, whereby reciprocal rotation of the movable blade of the hinge drives extension/contraction of the active rod and thus inducing reciprocal sliding movement of the limiting block within the limiting slots, so as to control an opening range of the hinge.
