BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cage system for a vertical circulation parking system having a cage guide supported on a support structure.

[0002]

2. Description of the Related Art Conventionally, a vertical circulation type multi-story parking device having a cage guide supported by a support structure is widely known (for example, see Japanese Utility Model Laid-Open No. 63-140450).

In such an apparatus, as shown in FIG. 5, an outer and inner cage guides b and c for guiding the cage a at the upside down portion of the cage a include a steel frame, a building body,
It is fixedly supported by supporting structures d and e such as a driving device.
At the bottom of the cage a, guide rollers f and g are provided inside and outside.
There is rotatably supported, Figure 5 the solid line of the cage circulation state to
Outer become guide roller f is the outer cage guidance b in the process of circulating like a virtual line, guide rollers g of the inner side are guided respectively by the inner cage guide c.
Further, the catarollers h and i rotatably supported on the upper part of the cage a are guided by the steady rest guide k.

[0004]

Therefore, when the cage a swings in the upside down portion of the cage a or is inverted while being tilted by the one-sided loading of the car, the guide rollers f and g of the cage a and the cage guide are rotated. b and c collide with each other, and at that time, an impact sound is generated, or the impact is vibrated and transmitted to the supporting structures d and e, thereby causing a noise vibration problem.
In addition, in the independent tower method, the impact becomes the excitation force,
The entire tower vibrates. As a result, a low-frequency sound is generated, causing a problem that the windows and glass of the surrounding houses vibrate rattle.

[0005] The original function of the cage guide is to forcibly guide the cage when the cage deviates from the normal circulation path, and it is essentially difficult to avoid collision between the cage and the cage guide. It is also difficult to adjust the positional relationship between the cage and the cage guide so that all the cages and the cage guide do not collide.

An object of the present invention is to provide a cage guide structure of a vertical circulation type parking device capable of suppressing the generation of noise and vibration by reducing the collision even if the cage and the cage guide collide. It is the purpose.

[0007]

The present invention is based on the cage guide structure of a vertical circulation type multi-story parking device having a cage guide supported by a support structure.

According to a first aspect of the present invention, the tip of the cage guide, which is located forward of the vicinity of the boundary between the cage linear motion guide and the curved motion guide, is a cantilever that is rotatably supported near the boundary, and the tip and the support structure are provided. An elastic member and a damping member are provided between objects.

According to a second aspect of the present invention, the front end of the cage guide, which is located near the boundary between the cage linear motion guide and the curved motion guide, is a cantilever fixedly supported near the boundary and formed of an elastic material. The damping member is provided between the tip and the support structure.

[0010]

According to the first aspect of the present invention, when the cage collides with the cage guide, the impact energy is converted into the potential energy of the elastic member, and the impact is reduced.

Next, the cage gradually separates from the cage guide and smoothly moves to a linear motion without colliding with the cage guide again. At the same time, the outer cage guide returns to its original position.

According to the second aspect of the present invention, when the cage collides with the cage guide, the impact energy is absorbed by the cantilever-shaped cage guide, and the impact is reduced.

Next, the cage gradually moves away from the cage guide and smoothly moves to a linear motion without colliding with the cage guide again. At the same time, the outer cage guide returns to its original position.

Guide rollers 11 and 12 are rotatably supported inside and outside of the lower part of the cage 3, and are shown by solid lines in FIG.
An outer in the process of circulating the over-di circulation state like a virtual line
The guide roller 12 is guided by the outer cage guides 1 and 2, and the guide roller 11 on the inner side is guided by the inner cage guide 9.

On the left and right of the upper part of the cage 3, there are rotatably supported cat rollers 13, and the cat rollers 13 are guided by a steady guide 14.

The upper outer cage guide 2 is inclined inward such that the inclined portion 9a of the inner cage guide 9 contacts the guide roller 12 before contacting the guide roller 11.

The spring constant k and Dan the coil spring 7
The damping coefficient c of the par 8 is set to an appropriate value so that the outer cage guide 2 does not vibrate even if an impact is applied to the outer cage guide 2 and smoothly returns to the original position while attenuating from the displacement position due to the collision. Is set.

With the above configuration, first, the cage 3
Starts from the top and circulates counterclockwise while oscillating or leaning in one side of the car.

[0030]

According to the first aspect of the present invention, the collision between the cage and the cage guide can be reduced by using the elastic member and the damping member without largely changing the conventional device. As a result, the impact noise is reduced, and the vibration transmitted from the cage guide to the support structure is also reduced, so that the generation of vibration noise is reduced. In the independent tower system,
Since the excitation force is reduced, the vibration of the tower is also reduced, and low frequency noise is reduced.

According to the second aspect of the present invention, since the cage guide has an elastic function, the same effect as the first aspect of the present invention can be obtained by omitting the elastic member.
