    • A telescopic rail mainly consisting of three, substantially C-shaped sections of which the inner or drawer section (3) is slidably mounted in the intermediate section (2) with interposition of a first ball cage and the intermediate section (2) is slidably mounted in the outer or cabinet section (1) with interposition of a second ball cage (7). Mounted at one end of the intermediate section (2) is a stop block (5) with resilient fingers (13) which can be brought into a coupling position wherein the inner section (3) is coupled to the intermediate section (2) and into a pass position wherein the inner section (3) can move independently of the intermediate section (2). The inner section (3) at one end thereof is provided with inwardly pointing projections (11) facing each other, which can cooperate with outwardlly pointing projections (12) facing away from each other, provided on the resilient fingers (13) of the stop block (5), which projections (12) in the coupled position of the sections are disposed in the path of travel of the projections (11) of the inner section (3). Arranged between the free ends of the resilient fingers (13) is a locking member (6) which can be moved in the axial direction of the telescopic rail.
    • 主要由三个基本上C形的部分组成的伸缩轨道,其内部或抽屉部分(3)可滑动地安装在中间部分(2)中,插入第一球笼和中间部分(2)可滑动地安装 在外部或机柜部分(1)中插入第二个球笼(7)。 安装在中间部分(2)的一端是具有弹性指状物(13)的止动块(5),该止动块可以进入联接位置,其中内部部分(3)联接到中间部分(2)并进入 通过位置,其中内部部分(3)能够独立于中间部分(2)移动。 在其一端的内部部分(3)设置有彼此面对的向内指示的突出部(11),所述突出部分可以与设置在所述止动件的弹性指状物(13)上的彼此背离的向外指向的突出部(12)配合, 块(5),在所述部分的联接位置中的所述突起(12)设置在所述内部部分(3)的所述突起(11)的行进路径中。 布置在弹性指状物(13)的自由端之间的是能够在伸缩轨道的轴向方向上移动的锁定构件(6)。
