Abstract:
1. A safe guard device for a multi-section slide track assembly, comprising: an inner slide track including a first end and a second end; an intermediate slide track adapted to receive the inner slide track; a limit member mounted to the intermediate slide track and actuated by a bias force for pivotal movement, the limit member including a distal end to engage with the first end of the inner slide track to provide a temporary space formed between an end of the intermediate slide track and the second end of the inner slide track for accommodating fingers of an operator holding on the second end of the inner slide track, and the limit member further including a guiding flange to cause the pivotal movement of the limit member, said limit member further comprising a pair of engaging holes at either side of an assembling hole of the limit member, and the intermediate slide track correspondingly includes a pair of protrusions to be received in the engaging holes of the limit member such that a range of the pivotal movement of the limit member being confined; and an outer slide track including a press plate to engage with the guiding flange of the limit member so as to unlock the engagement of the first end of the inner slide track with the distal end of the limit member; wherein when the inner slide track is initially retracted to a predetermined position into the intermediate slide track, the first end of the inner slide track is engaged with the distal end of the limit member to provide the temporary space formed between the end of the intermediate slide track and the second end of the inner slide track to avoid catching the fingers, and a combination of the inner slide track and the intermediate slide track is formed; wherein when the combination of inner slide track and the intermediate slide track is further retracted into the outer slide track, the press plate of the outer slide track presses the guiding flange of the limit member to cause the pivotal movement so that the engagement of the first end of the inner slide track with the distal end of the limit member is unlocked, thereby permitting the inner slide track to retract into the intermediate slide track.
