Abstract:
1. A retaining mechanism for a multi-section slide track assembly, comprising: a stop actuating assembly mounted on an intermediate slide track which provides at least one operation window, the stop actuating assembly including a stop-engaging member and a resiliently actuating member, the stop-engaging member having at least one engaging lug extended through the operation window, the resiliently actuating member having at least one actuating lug extended through the operation window, the resiliently actuating member further including a first resilient arm providing a spring force, and at least one first pressing guide edge being pressed by an inner slide track for releasing operation; and a resilient retainer assembly mounted on an outer slide track, the resilient retainer assembly including a resilient stop member and a limit member, the resilient stop member having a head piece and at least one second pressing guide edge being pressed by the resiliently actuating member of the stop actuating assembly, the second pressing guide edge 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, the limit member having a second resilient arm, the second resilient arm exerting an upward spring force on the head piece of the resilient stop member to limit an unexpected downward movement; 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; and 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 disengaged from the engaging lug of the stop-engaging member.
