Description

Rope device for elevator Technical Field The present invention relates to a rope device for an elevator, which connects a main rope suspending a car to a car frame. Background In a conventional rope device of an elevator provided on a car frame, a main rope is connected to a rope shackle disposed on a car room side of the car frame via the car frame. The rope shackle connected to the end of the main rope is disposed between the car frame and the car room, and is disposed so as to protrude from the car frame toward the car room. (for example, refer to patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 4-94386 When the rope shackle is disposed so as to protrude from the car frame toward the car room, a space in the longitudinal direction for disposing the rope shackle needs to be secured between the car frame and the car room. Therefore, the space between the car frame and the car room cannot be reduced to a size equal to or smaller than the longitudinal dimension of the rope shackle, and therefore, there is a problem that it is difficult to reduce the total height of the car frame. In addition, when it is difficult to reduce the total height of the car frame, there is a case where an Overhead (OH) dimension required for the upper portion of the hoistway is affected. Disclosure of Invention The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a rope device for an elevator, which is capable of reducing the total height of a car frame without being affected by the longitudinal dimension of a rope shackle when the rope shackle is disposed at the upper portion of the car frame. The rope device for an elevator comprises an elastic body and a rope shackle, wherein the elastic body is arranged on a car frame, a plurality of main ropes suspending the car frame are elastically supported on the car frame, the car frame is supported in a car chamber which is lifted in an elevator shaft, the elastic body is supported on the rope shackle, the rope device connects the main ropes with the car frame, and the rope device for the elevator is characterized by comprising a rotating shaft which is fixed on the car frame, and a swinging part which is rotatably supported by the rotating shaft and can swing in a lever shape along the direction of the tension action of the main ropes, one side of the swinging part is connected with the end part of the main ropes, and the other side of the swinging part is connected with the rope shackle. Effects of the invention The invention can realize a rope device of an elevator, which can reduce the total height of a car frame without being influenced by the dimension of the rope shackle in the length direction when the rope shackle is arranged at the upper part of the car frame.
