Abstract:
1. A multi-section slide track assembly, comprising: an outer slide track; an intermediate slide track slidably connected to the outer slide track and having at least one operation window; an inner slide track slidably connected to the intermediate slide track; a stop-engaging member mounted on the intermediate slide track and having at least one engaging lug extended through the operation window of the intermediate slide track; a resiliently actuating member mounted on the intermediate slide track and including at least one actuating lug extended through the operation window of the intermediate slide track, a first resilient arm providing a spring force, and at least one first pressing guide edge being pressed by the inner slide track for releasing operation; a resilient stop member mounted on the outer slide track and including a second resilient arm providing an upward spring force so as to upraise the resilient stop member, and at least one second pressing guide edge being pressed by the resiliently actuating member and including an end to form a stop portion to engage with the engaging lug of the stop-engaging member such that a return movement of the intermediate slide track is limited; a limiting ring disposed on the outer slide track to confine a range of an upward movement of the second resilient arm of the resilient stop member; wherein when the intermediate slide track is fully extended from the outer slide track, the stop portion of the resilient stop member is engaged with the engaging lug of the stop-engaging member; wherein when the inner slide track is retracted along the intermediate slide track to press the first pressing guide edge of the resiliently actuating member in a return movement, the actuating lug of the resiliently actuating member presses the second pressing guide edge of the resilient stop member such that the stop portion of the resilient stop member is disengage from the engaging lug of the stop-engaging member; and wherein the second resilient arm of the resilient stop member is passed through the limiting ring, and an end of the second resilient arm is engaged with a surface of the outer slide track due to pressing by the limiting ring of the limit member.
