    • Display apparatus having a rail fixable on a stationary structure and provided with a groove, a sliding member fittable in the rail groove and slidable therealong, a wire or cord coupled to the sliding member, a gripping member through which the wire or cord passes, a supporting hook connected to an end of the wire or cord remote from the gripping member, and a second rail having a groove for receiving the hook such that the wire or cord is coupled to the second rail and is tensioned when installed. The gripping member through which the wire or cord passes, comprises a hollow member having an inner tapered surface, a sleeve member having a passage formed therein for the wire or cord and situated within the hollow member to be freely slidable with respect thereto with at least a portion of the sleeve member projecting out from the hollow member, and at least one ball captured in the sleeve member seating against the tapered inner surface of the hollow member and communicating with the passage. A spring urges the sleeve member in a direction in which the inner surface of the hollow member tapers.
    • 显示装置具有可固定在固定结构上并具有凹槽的轨道,可装配在轨道槽中并沿其滑动的滑动构件,连接到滑动构件的导线或绳索,线或线通过该夹持构件, 连接到远离抓握构件的线或线的端部的支撑钩,以及具有用于接收钩的凹槽的第二轨道,使得线或绳连接到第二轨道并且在安装时被张紧。 电线或电线穿过的夹持构件包括具有内锥形表面的中空构件,套筒构件具有形成在其中的用于电线或电线的通道,并且位于中空构件内,以至少可自由地滑动 套筒构件的一部分从中空构件突出,并且至少一个捕获在套筒构件中的球抵靠中空构件的锥形内表面并与通道连通。 弹簧沿着中空构件的内表面逐渐变细的方向推动套筒构件。
