  • Patent number: 8556305
    Abstract: A locking/unlocking apparatus for a drawer is applicable to be assembled on a fixed slide rail and a slidable slide rail of a drawer or on a drawer body and a drawer cabinet. The locking/unlocking apparatus comprises a drive element disposed on the slidable slide rail or the drawer body, a main body fixed on the fixed slide rail or the drawer cabinet, a slide block slidably disposed on the main body, and a spring disposed between the main body and the slide block. By such arrangements, when the drawer is pulled by a large force, it can prevent the slide rails, the drawer body or the locking/unlocking apparatus from being damaged.

  • Patent number: 8393693
    Abstract: A return device for a drawer employs an actuator to drive a slide block, when the drawer is pulled open, the slide block is moved into a positioning concave and positioned therein while stretching an elastic member. Or pushing the drawer back can make the slide block slide out of the positioning concave, meanwhile, the elastic member pulls the drawer back to its original position. Furthermore, since the angle between the slide surface of the positioning concave of the positioning member and the track is obtuse, it is easy for the slide block to slide in and out, so that the drawer can be easily positioned and unlocked from the positioned state.

  • Patent number: 8371664
    Abstract: An interlocking device for a drawer slide is provided with an outer board, a fixed seat, two linkage members, a middle board, a restricting member and an inner board. When one of the drawers in a cabinet is pulled toward the first end of the outer board, the inner board will be moved together with the drawer and push the restricting member, the middle board and the actuating block, then the two linkage members are pushed to move in an opposite direction to the Y direction, the two connecting rod are caused to push the linkage members of other interlocking devices, so that the inclined surface of the guiding portion of one of the linkage members of other interlocking devices will be received in the receiving space and abutted against the inclined guiding surface of the actuating block of the middle board to prevent other drawers from being pulled out.

  • Patent number: 8240788
    Abstract: A hidden self-closing drawer slide assembly comprises a base, a pressure cylinder, a traction member and a spring. The traction member is movably received in the base. The traction member is provided with a guiding block. The base is formed with a slide groove, and one end of the slide groove is folded into a positioning portion. The guiding block guides the traction member to linearly moves in the slide groove, and slides through the slide groove and finally into the positioning portion, and the locking protrusion of the traction member will disengage from the concave locking portion of the pressure cylinder. The traction member will be pushed back by the spring to its original position, and the pressure cylinder provides a buffering effect to absorb the shock.
