Description

  The present invention relates to an elevator, and more particularly to an elevator having a mechanism for preventing damage caused by contact of a tail cord with a car.

  In order to supply power from the building side to the lighting system and other electrical systems in the elevator car, and to exchange control signals with the car and the elevator controller, the elevator controller and the car are connected by a tail cord. It is. The tail cord is hung to the side of the car in the elevator hoistway so that it does not become an obstacle when the car moves up and down. The tail cord vibrates because the connecting end portion of the car ascends and descends when the car moves up and down, and the slack portion may come into contact with the side surface of the car.

  In order to prevent slipping of the tail cord due to contact with the car, conventionally, a measure to attach a sliding tape to the portion that may come into contact with the tail cord on the side of the car may be taken. there were.

  However, with measures such as attaching sliding tape to the side of the car, the frictional noise that occurs when the tail cord comes in contact with the side of the car and moves up and down cannot be reduced, and the frictional sound propagates to passengers in the car. There was a problem that caused discomfort. Further, it is insufficient to reduce the contact friction between the car and the tail cord by the sliding tape, and there is a problem that the tail cord may be damaged by long-term use.

  The present invention has been made in view of the above-described conventional technical problems, and by effectively reducing the contact friction resistance between the tail cord and the car, the tail cord can be prevented from being damaged due to rubbing against the cage. An object of the present invention is to provide an elevator equipped with a mechanism capable of reducing frictional noise.

  The present invention is characterized in that an elevator is provided with a cord support device comprising a roller that contacts and rotates with a tail cord, one end of which is connected to the car, and a support member that supports the roller.

  Further, the present invention is characterized by an elevator in which a cord support device comprising a roller that rotates in contact with a tail cord having one end connected to a car and a support member that rotates and supports the tail cord is connected to the inner wall of the hoistway.

  According to the elevator of the present invention, the roller of the cord support device installed on the side surface of the car can rotate when contacting the tail cord to reduce its frictional resistance and to suppress the generation of frictional noise. It is possible to prevent damage caused by rubbing against the cage, and to prevent the passenger from feeling uncomfortable with the friction sound.

  Further, according to the elevator of the present invention, the cord support device installed in the hoistway prevents the tail cord and the car from coming into contact with each other, and the roller rotates when contacting the tail cord to reduce its frictional resistance. It is possible to prevent damage caused by rubbing the tail cord against the car, and to prevent the tail cord from coming into contact with the side of the car and generating frictional noise.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 3, the elevator according to the present embodiment has a tail between a bottom portion of the car 1 that moves up and down in the hoistway 10 and an elevator control device installed on the upper portion of the hoistway 10 that is not shown. A cord 2 is connected, and an intermediate portion of the tail cord 2 is suspended by natural gravity. The tail cord 2 is a cable for transmitting a control signal between the elevator control device and the car 1 and supplying power.

  The car 1 includes a car room 1a for accommodating passengers and a car frame 1b for supporting the car room 1a. And the code | cord support apparatus 3 is installed in the position which contacts the tail cord 2 in the side surface of the cage | basket | car 1, ie, the cage frame 1b, respectively up and down.

  The cord support device 3 includes a roller support member 3a attached to the car frame 1b and a roller 3b supported by the roller support member 3a. The roller 3b rotates in contact with the tail cord 2, reduces the frictional resistance caused by the contact with the tail cord 2 when the car 1 moves up and down, prevents the tail cord 2 from being damaged by friction, and generates a frictional sound. Suppresses the occurrence. The roller 3b in the cord support device 3 is formed of a material having flexibility and durability such as urethane material even at least on the surface portion.

  In the elevator according to the present embodiment, when the car 1 is lifted and lowered in the hoistway 10, the tail cord 2 hanging in the hoistway 10 contacts the car 1, but the cord support provided at an appropriate position is provided. The roller 3b of the apparatus 3 rotates while being in contact with the tail cord 2 to prevent the car 1 and the tail cord 2 from being rubbed strongly by the raising / lowering operation of the car 1, and the tail cord 2 is prevented from being damaged. Further, since the car 1 is not rubbed strongly against the tail cord 2, no frictional sound is generated, and the passenger in the car room 1a can be prevented from feeling uncomfortable with the frictional sound.

  In the elevator according to the present embodiment, the cord support devices 3 are installed at two locations above and below the car 1. However, the cord support devices 3 may be installed at more locations than that, and if effective, only one location is provided at an appropriate location. May be. Further, as shown in FIG. 1, for the purpose of guiding the tail cord 2, it can be installed at an appropriate place, one place or a plurality of places on the inner wall of the hoistway 10.

  In addition, the roller 3b of the cord support device 3, as shown in each of FIGS. 4A to 4C, is a roller that is curved so that the central portion is recessed, a tapered roller, or a chain-shaped roller. It may be.

  Further, as shown in FIG. 5, the structure of the cord support device 3 is such that guide rollers 3c are separately provided inside the both ends of the roller support member 3a so as to support the tail cord 2 from both sides. It can also be.
