Abstract: A track device comprises a first track and a second track. An engaging member is mounted to an end of the first rack and includes at least one leg and at least one operative wall. The first track further includes an upper longitudinal lip and a lower longitudinal lip. The second track is slidably received in the first track and guided between the upper longitudinal lip and the lower longitudinal lip. A pressing block and a resilient member are mounted to the second track. The pressing block includes a pressing leg and a shoulder. The pressing leg presses against an end of the resilient member. The end of the resilient member includes a tappet plate. Another end of the resilient member includes a pressing portion. The shoulder of the pressing block abuts against the leg of the first track. When the pressing portion of the resilient member is pressed, the tappet plate of the resilient member moves the leg such that the operative wall of the engaging member disengages from the shoulder of the pressing block, thereby allowing separation of the second track from the first track.

Abstract translation: 轨道装置包括第一轨道和第二轨道。 接合构件安装到第一齿条的端部并且包括至少一个腿部和至少一个操作壁。 第一轨道还包括上纵向唇缘和下纵向唇缘。 第二轨道可滑动地容纳在第一轨道中并在上纵向唇缘和下纵向唇缘之间引导。 按压块和弹性构件安装到第二轨道。 按压块包括按压腿和肩部。 按压腿压靠弹性构件的一端。 弹性构件的端部包括挺杆板。 弹性构件的另一端包括按压部。 按压块的肩部抵靠第一轨道的腿部。 当弹性构件的按压部分被按压时，弹性构件的挺杆板使腿部移动，使得接合构件的操作壁与按压块的肩部脱离，从而允许第二轨道与第一轨道 。
