Description of the Related Art FIG. 3 is a front view showing a schematic structure of a conventional vibration isolator for a moving cable of this type disclosed in Japanese Utility Model Publication No. 54-23068. In the figure, 1 is a peripheral wall of an elevator hoistway, 2 is a car suspended and supported by a hoisting rope 3, 4 is a U-shaped curved portion 4a formed between the car 2 and the peripheral wall 1, and is suspended. The movable cables 5 are anti-vibration tools in which a metal round bar ring slidably inserted in the movable cable 4 is coated with nylon resin or the like.

に引掛って破断したり、接触損傷することもある。In such a case, the mobile cable 4
Are generally hung together. That is, the moving cable 4 is usually composed of about 20 to 40 core wires, and the bending portion 4a moves up and down as the car 2 moves up and down. In order to prevent an accident in which the core wire of the moving cable 4 is broken by the repeated bending action due to this movement, the core wire of the moving cable 4 is configured by twisting a large number of strands. As described above, since the moving cable 4 has a complicated structure, some distortion occurs inside the moving cable 4. Then, each moving cable 4 suspended between the car 2 and the peripheral wall 1 horizontally sways in various manners when the bending portion 4a moves up and down due to internal strain. Also,
Each moving cable 4 vibrates separately due to rolling due to external factors such as building wind. Therefore, it may be broken or contact-damaged by being caught on other equipment or device (not shown) of the elevator shim-them arranged in the peripheral wall 1.

Regardless of the movement of the movement cable 4, the movement cable 4 is retained in the bending portion 4a to suppress the movement.

ブル４が破損する等の問題点があった。However, since the conventional vibration isolator for a moving cable is constructed so that the weight of the vibration isolator 5 is supported by one point of the curved portion 4a of the movable cable 4,
The sliding of the vibration isolator 5 causes the surface of the moving cable 4 to wear. Further, if the friction coefficient is large, there is a problem that the vibration isolator 5 is lifted as the car 2 rises, and the moving cable 4 is damaged by the impact when falling.

FIG. 1 is a front view showing a schematic configuration of a vibration isolator for a moving cable according to a first embodiment of the present invention, in which parts corresponding to the conventional ones are designated by the same reference numerals. In the figure,
Reference numeral 6 denotes a hollow flexible body, that is, a flexible pipe, which is attached to the moving cable 4 or is integrated by belt fastening or the like, and its length is set to the same length as the moving cable 4. Reference numeral 7 is a liquid such as water in which an appropriate amount (about 1/2 of the internal volume of the flexible pipe in this embodiment) is enclosed in the flexible pipe 6, and other configurations are the same as the conventional one.

したものである。In the apparatus of the present embodiment constructed as described above, the bending portion 4 of the moving cable 4 is accompanied by the raising and lowering of the car 2.
When a moves up and down, the bending portion 6a of the flexible pipe 6 integrated with the moving cable 4 also moves up and down. However, the liquid 7 in the flexible pipe 6 moves and stays in the bending portion 6a due to gravity, and the bending portion 4a of the moving cable 4 is retained.
The weight of the moving cable 4 is always added to the center of the curved portion 4a. That is, the liquid 7 in the flexible pipe 6 functions as a weight of the dynamic vibration absorber, so to speak, to suppress the vibration of the moving cable 4 and to damp it. In order to utilize such vibration damping effect of liquid, for example, a number of tanks filled with about half the liquid are installed on the roof of a building, etc., and the vibration of the building during an earthquake is absorbed. A vibrating structure can be mentioned. The present invention utilizes the same principle as the vibration damping of such a building so as to obtain the vibration damping action by the liquid weight on the moving cable 4 and the vibration damping action accompanying the movement of the liquid.

The bending portion 6a of the flexible pipe 6 integrated with the moving cable 4 also moves up and down. However, the powder 8 in the flexible pipe 6 moves and stays in the bending portion 6a due to gravity,
Weight is always added to the curved portion 4a of the moving cable 4 so that the center of gravity of the moving cable 4 always comes to the center of the curved portion 4a. That is, the powder 8 in the flexible pipe 6 also
In the same manner as the liquid 7 of the first embodiment, it functions as the weight of the dynamic vibration absorber, and suppresses the vibration of the moving cable 4 and attenuates it.
