Abstract

PURPOSE: To prevent a rolling or yawing vibration caused in a car through a simple structural alteration by providing a stabilizer rail arranged in an elevator shaft in parallel to a guide rail and a stabilizer roller to engage with the stabilizer. CONSTITUTION: A stabilizer rail 38 is arranged in an elevating passage 4 so that a guide part 40 formed of a T-shaped leg part may be parallel to a side wall of an elevating car 2, and a bracket 42 to support the rail 38 is attached to the bracket 36 of a guide rail 22 for a counterweight. The rail 38 is joined to the bracket 42 using a clamp 44. A pair of stabilizer rollers 48 is rotatably supported through an attaching member 50 fixed to a beam on the beam 46 protruding from the corner 14 of the elevating car 2, and a roller 48 abuts on both the end faces of the guide part 40 of the rail 38. Thus the rail 38 and the roller 48 can also control any lateral oscillating motion of the elevating car 2 and can effectively control the rolling vibration of the elevating car.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an elevator system, and more particularly to a guide device for guiding the vertical movement of an elevator car in a vertical passageway.

Furthermore, the present invention relates to a guide device for an elevator car that uses three guide rails to suppress lateral vibrations of the car.

As is well known in the prior art, the elevator car is guided in its lifting motion by guide rails within the elevator passageway. Conventionally, guide roller units each consisting of three rollers or wheels are provided on both sides of the floor of the elevating cage, and similar guide roller units are also provided on both sides of the ceiling. The guide rail is usually formed in a T-shape, and is provided with T-shaped legs protruding toward the side of the elevator cage. The three rollers of each guide roller unit come into contact with the end and both side surfaces of the T-shaped leg of the guide rail to guide the lifting and lowering movement of the elevator cage.

In normal cases, the combination of the two guide rails and the guide roller unit can guide the lifting and lowering movement of the elevator car in a sufficiently smooth and stable manner.

Only the problem that the invention attempts to solve is 1. Therefore, if the elevator car is long, for example, if it has a deep structure such as one with doors for getting on and off on both sides, lateral vibrations will occur in the elevator car. This tendency becomes particularly strong when the elevator cage is operated at high speed. Such rolling vibrations not only cause discomfort to the passengers, but also may upset the passengers if the rolling vibrations are severe.

It is an object of the present invention to provide a lifting cage guide device that has the following features.

Yet another object of the present invention is that the guide portion of the auxiliary guide rail with which the guide roller engages is disposed in a direction perpendicular to the guide portion of the main guide rail, thereby preventing the horizontal shaking of the elevator car. An object of the present invention is to provide an elevating cage guide device configured to support the corners of an elevating cage in order to prevent such problems.

This will be explained with reference to the attached drawings.

In the figure, a lifting belt 2 is provided within a lifting passage 4 so as to be movable up and down. In the illustrated example, the elevator belt 2 has doors for getting on and off on both sides in the front-back direction, and one door is provided in the front portion 6. In this front part 6,
A plate member 8 functioning as a sill and a toe guard is formed to extend downward from the floor 10 of the lift zone 2 within the lift passage 4. In the first figure, the wall portion 111 on the near side
2 is shown partially cut away to show the internal configuration. The portion 14 is a vertical corner where the edge of the front portion 6 where the door is disposed joins with the adjacent side wall. A pair of main guide rails 16 are disposed in the lifting passage parallel to the longitudinal axis of the lifting passage.

The main guide rails 16 are located opposite to both sides of the elevator cage 2. Each guide rail 16 is formed in a T-shape when viewed in cross section, and the T-shaped legs form guide portions 18 extending toward each opposing side wall of the elevator cage 2 .

It is in contact with the edge and side of the In the figure, only the guide roller unit disposed on one side of the elevating cage 2 is shown, but a similarly configured guide roller unit is also disposed on the other side of the elevating cage. Together with the main guide rail 16, these guide roller units guide the elevator cage so that the elevator cage 2 moves up and down smoothly and stably within the elevator passageway 4.

A pair of guide rails 20 and 22 for a counterweight are roughly arranged in the lifting passage 4. Guide portions 24.26, which are formed by T-shaped legs of these counterweight guide rails 20.22, face each other and guide the lifting and lowering movements of the counterweight frame 21 (see FIG. 2). ing.

In FIG. 1, when the elevator cage 2 is a deep elevator cage whose length in the front and back direction is longer than the length in the lateral direction between both side walls, the guide rail I6 and the guide rollers 30, 32 Lateral rotational vibration may be generated around the rotational axis formed by .34, and this lateral vibration becomes more likely to occur as the lifting speed of the elevator cage increases. Nowadays, there is a tendency for the lifting and lowering speeds of the lifting cars to become faster.In some high-speed elevators, the lifting and lowering speeds of the lifting cars are as high as 16 feet per minute. Lateral vibration is a problem.

In order to prevent rolling vibrations of the elevator car, stabilizer rails 38 are provided in the elevator system according to the preferred embodiment of the invention. This stabilizer rail 3
