Abstract:
A track device comprising:a first track comprising an upper longitudinal lip and a lower longitudinal lip, a retaining member, the retaining member comprising plural legs, a mounting member and a positioning hole, an engaging slot adapted for securely receiving the mounting member and a positioning block adapted to be securely engaged with the positioning hole; a second track slidably received in the first tract and guided between the upper longitudinal lip and the lower longitudinal lip of the first track, the second track comprising a pressing block, the pressing block comprising plural protrusions for pressing against the plural legs of the retaining member; and wherein the second track is mounted in the first track and pulled outward to a predetermined position, the legs of the retaining member press against inner sides of the protrusions of the pressing block to thereby prevent inadvertent inward movement of the second track in the first track, and when the second track in the predetermined position is pushed inward by an appropriate force, the protrusions of the pressing block press against and thus deform the legs of the retaining member to thereby allow the protrusions of the pressing block to move across the retaining member, thereby allowing inward movement of the second track in the first track.
