Abstract

PURPOSE:To prevent vibration and noise generated by the stick-slippage of a guide shoe at the time of starting an elevator car. CONSTITUTION:A rubber vibration insulator is mounted between a shoe supporting member 6 where a shoe is incorporated and a frame formed so as to cover it, and the upper ends 10a and 10b of a leaf spring 10 are fixed on the shoe supporting member 6 through a seat 13. Moreover, the central part 10c of the leaf spring 10 is fixed on the frame 8 through a seat 14 to regulate a displacement in the vertical direction of the shoe. It is thus possible to prevent a shoe from stick-slippage and to eliminate generation of vibration and noise in a guide shoe at the time of starting an elevator car or immediately before stopping the elevator car.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide shoe which is arranged in a car of an elevator and guides the car along a guide rail.

[0002]

2. Description of the Related Art As shown in FIG. 4, elevator guide shoes 1 are arranged at the top, bottom, left and right ends of a car frame 2 and guide a car 4 along guide rails 3.

Conventionally, as an elevator guide shoe,
As described in JP-B-58-19584, a vibration-proof rubber is provided between a shoe support member incorporating a shoe and a frame provided so as to cover the shoe support member. There has been devised a structure in which a stopper is provided in the direction of the support member so as not to come into contact with the anti-vibration rubber and constitutes a stopper that restricts lateral deformation of the anti-vibration rubber.

[0004]

The above-mentioned prior art does not consider the vertical displacement regulation of the anti-vibration rubber, and therefore, the car does not start when it is started or when it is decelerated and immediately before stopping. The frictional force between the shoe and the guide rail causes the shoe to make a stick slip, which causes abnormal vibration and noise from the guide shoe, which is transmitted to the cab and gives passengers a discomfort.

An object of the present invention is to prevent stick-slip of shoes and to prevent abnormal vibrations and noises, and to provide an elevator guide shoe having a good vibration prevention effect during traveling. .

[0006]

The above object is to provide a leaf spring having high rigidity in the vertical direction between the shoe support member and the frame,
By controlling the vertical displacement of the anti-vibration rubber, the stick-slip of the shoe is prevented, and in order to improve the vibration prevention effect during traveling, it is achieved by reducing the lateral rigidity of the leaf spring. It

[0007]

The leaf spring provided between the shoe support member incorporating the shoe and the frame is easily bent in the lateral direction and has a high rigidity in the vertical direction. Therefore, the spring constant of the guide shoe changes little in the lateral direction. The vertical displacement of the can be regulated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 is a side view of a guide shoe of the present invention, FIG. 2 is an elevation view, and FIG. 3 is a front view.

The shoe 5 is held by a shoe support member 6,
One end 7 of the anti-vibration rubber 7 is provided on both side surfaces 6a of the shoe support member.
Further, the other end 7b of the vibration-proof rubber 7 is fixed to a frame 8 provided so as to cover the shoe support member. Bolts 9a, 9 for fixing anti-vibration rubber are provided on two opposite side surfaces 8a of the frame 8.
b is vertically attached to the side surface. Further, the upper end 10 a of the leaf spring 10 provided between the shoe support member 6 and the frame 8
And the lower end 10b is bent into an L shape, and the upper end 10a and the lower end 10b are fixed to the shoe support member 6 by bolts 11a and 11b via the seat 13 to the one end 7a of the vibration isolating rubber 7,
The center 10c of the leaf spring 10 is fixed to the frame 8 by a bolt 12 via a seat 14. Since the leaf spring 10 has a high rigidity in the vertical direction, it functions as a stopper against the displacement of the shoe in the vertical direction. Further, since the seat 13 and the seat 14 are provided and fixed in the lateral direction to easily bend, the change in the spring constant of the guide shoe in the lateral direction is small.

According to this embodiment, since the change in the spring constant of the guide shoe in the lateral direction is small, the lateral vibration characteristic of the car does not change, and the vertical displacement of the guide shoe can be restricted. The stick slip is eliminated and the abnormal vibration noise of the guide shoe can be prevented.

[0011]

According to the present invention, the lateral vibration of the guide shoe is reduced by providing a leaf spring which is easily bent in the lateral direction and has high rigidity in the vertical direction between the shoe support member incorporating the shoe and the frame. Since the vertical displacement of the shoe can be restricted without impairing the characteristics, abnormal vibration noise of the guide shoe at the time of starting the car or immediately before the stop of the car does not occur, and an elevator with a comfortable ride can be provided.
