Abstract

PURPOSE: To prevent a cable from swinging to the left/right in vertically moving the cable along with a car by providing a magnetizing layer attracting the cable to a magnetic member in a hoistway on a surface of the cable extended from a machine chamber and attached to the cage. CONSTITUTION: This elevator has a cable 10 extended from a machine chamber 9 toward a car 1. The cable 10 is trained over an inner wall till the intermediate position of a hoistway 2, after that rested against a cable hanger 11 and suspended therefrom, and locked to a floor face 1a of the car 1. The cable 100 is provided with a power line 12 and a signal wire 13 stored in a vinyl sheath 14 and a magnetizing film 15 in the surface in one end. On the other hand, an iron plate (magnetic member) is provided in the hoistway 2 and positioned in a place from which the cable 10 is suspended. The cable 10 is thus attracted to the iron plate 16 by the magnetizing film 15 so as to be prevented from swinging to the left/right.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an elevator having a cable extending from a machine room to a car.

[0002]

2. Description of the Related Art Conventionally, a car operation panel is provided in an elevator car, and a signal is output from the car operation panel to a machine room or a drive current is supplied to a door operator provided in the car. The cable to do this is attached to the car. The cable is extended from a machine room located above the hoistway, is attached so as to crawl on the inner wall of the hoistway, and is hung from the middle to fix the tip to the floor of the car.

[0003]

When the car is moved up and down, the cable also moves up and down together with the car. At this time, since the substantially lower half of the cable hangs down from the car, this cable will sway left and right when moving up and down.

Here, since there are many protrusions on the inner wall of the hoistway, when the cable sways greatly to the left or right, it may be caught by the protrusions. Then, there was a fear that this cable might break.

Further, when the cable sways greatly to the left and right, the cable is attached to the floor surface of the car, so that there is a problem that the car is affected and riding comfort deteriorates.

[0006] It is an object of the present invention to provide an elevator in which the cable does not shake left and right when the cable moves up and down together with the car.

[0007]

In order to achieve such an object, according to the present invention, a car that moves up and down in a hoistway, a cable extended from a machine room and attached to the car, and a hoist A magnetic member provided in the path and a magnetizing layer provided on the surface of the cable to attract the cable to the magnetic member are provided.

[0008]

[Function] When the car is moved upward by the hoist, the cable is also moved upward by the car. However, since this cable is attracted to the magnetic member, it is pulled upward while being separated from the iron plate. Become. Next, when the cable is moved downward together with the car, the cable is sequentially attracted to the iron plate again.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 to 3 show an embodiment of an elevator according to the present invention.

In FIG. 1, reference numeral 1 is a car that is vertically movable in a hoistway 2, and the car 1 is guided by a pair of guide rails 3 and 4 provided upright in the hoistway 2. ing. One end of the rope 5 is fixed to the top of the car 1,
The rope 5 is hung on the drive sheave 6a of the hoisting machine 6, and then the other end is fixed to the counterweight 8 via the deflecting sheave 7.

A door operator (not shown) for opening and closing the door is provided on the top of the car 1, and a car operation panel (not shown) is provided in the car 1. From the machine room 9 to the car 1 in order to supply a drive current to the door operator from the power supply of the machine room 9 located at the top of the hoistway and to output a signal from the car operation panel to the control panel of the machine room 9. The cable 10 is extended toward.
The cable 10 is laid on the inner wall of the hoistway 2 from the machine room 9 to an intermediate position of the hoistway 2, and then the cable hanger 11 that is laid across the hoistway 2 in the future.
It is hung down after being put on the floor, and the tip of this is the floor part 1 of the basket 1.
It is attached to a.

As shown in FIG. 2, the cable 10 is provided with a power supply line 12 for supplying a drive current, a signal line 13 for inputting / outputting a signal, and the like in a vinyl sheath 14. The cable 10 has a substantially flat cross section, and the magnetized film 1 in which magnetic powder of a permanent magnet is mixed is formed on the surface on one end side.
5 are provided.

On the other hand, a plate-shaped iron plate 16 (magnetic member) is provided in the hoistway 2 as shown in FIG.
Is located where the cable 10 hangs. Since the cable 10 is provided with the magnetizing film 15, the cable 10 is attracted to the iron plate 16 by the magnetizing film 15.

When the car 1 is moved upward by the hoisting machine 6, the cable 10 is also moved upward by the car 1, but since the cable 10 is again adsorbed by the iron plate 16, it is separated from the iron plate 16. It will be pulled upwards. Next, when the cable 10 moves downward together with the car 1, the cable 10 is sequentially attracted to the iron plate 16. In this way, the cable 10 is attracted to or peeled off from the iron plate 16,
It does not shake greatly when moving up and down.

[0015]

As described above, according to the present invention,
Since the magnetic material is provided in the hoistway and the magnetized layer is provided on the surface of the cable, the cable does not sway greatly to the left or right when the cable moves up and down together with the car. As a result, the cable is not caught by the protrusion on the inner wall of the hoistway, and the cable is not broken. Further, the cable does not affect the car, and the riding comfort is improved.
