Title: Telescopic drawer slide with soft sequencing latch
Inventor: PARVIN JACKIE D
IPC: A47B88/49
Filed: 1998-02-06
Granted: 2007-04-17
Abstract: A sequencing latch adapted for use with drawer slides. The sequencing latch comprises a latch arm (51) carried by a slide member (26), a spring arm (63) extending from the latch arm in compressive contact with the slide member biasing the latch arm into engagement with a locking element (77) on a second slide member (41) and an actuator (91) on a third slide member (11) for disengaging the latch arm. The actuator disengages the latch arm by applying a force to the latch arm with a component oppositely directed and of sufficient magnitude to overcome the compressive spring force. Interaction of the locking element with the latching arm and the interaction of the actuator with the latching arm may both serve as frictional interfaces during slide operation.
