Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail for an elevator which is provided in a hoistway of a building and guides a car or a counterweight to travel.

[0002]

2. Description of the Related Art When an elevator is installed in a building, guide rails for cars and counterweights are first carried into a hoistway of the building. A plurality of the guide rails are connected to each other so as to extend in a vertical direction while being successively added, and are installed at a predetermined position.

Conventionally, such guide rails have been manufactured using iron as a raw material. Then, distortion generated during the manufacturing process is removed, and the surface and the end face are cut and finished.

[0004]

However, in the case of an iron guide rail, removal of distortion and cutting of the surface and the end face are required at the time of its manufacture as described above, which makes the manufacture troublesome and increases the cost.

[0005] Since the material is iron, the weight of each guide rail is heavy, and it is difficult to transport a large amount of guide rails at one time, and the transportation cost is high.
Installation work in the hoistway is also cumbersome.

Further, if the material is iron, vibration and noise generated when a car or a counterweight passes through a joint portion when a plurality of wires are added to the surrounding room using the guide rail as a medium. There is a problem of propagation.

Also, if the material is iron, there is a problem of rust,
For example, when a guide rail is visually exposed to the outside as in an observatory elevator, the guide rail is rusted and discolored, thereby deteriorating the external appearance.

[0008] The present invention has been made in view of such a point, and its object is to make it easy to manufacture, to reduce the weight, and to suppress the propagation of vibration and noise. An object of the present invention is to provide an elevator guide rail that can enhance the appearance.

[0009]

SUMMARY OF THE INVENTION The present invention is characterized in that the guide rail is made of synthetic resin in order to facilitate manufacture and reduce weight.

In order to enhance the appearance of the guide rail, a colored synthetic resin is used as the material.

In addition, the cross-sectional shape of the guide portion of the guide rail with which the guide member provided on the car or the counterweight comes into contact is made triangular so that the car and the counterweight are prevented from rolling or vibrating.

A metal member is attached to a guide portion of a guide rail with which a guide member mounted on a car or a counterweight comes into contact, thereby reinforcing the guide member.

[0013] A low friction material is attached to the guide portion of the guide rail, which comes into contact with the guide member mounted on the car or the counterweight, to improve the smoothness of running of the car or the counterweight and improve the riding comfort.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a guide rail 1 according to a first embodiment of the present invention. The guide rail 1 is formed of a synthetic resin having high strength and excellent wear resistance.

The guide rail 1 comprises a base portion 2 and a guide portion 3 integrally projecting from one side surface of the base portion 2.
A guide member provided on the car or the counterweight comes into contact with the guide section 3 so that the guide of the traveling is fulfilled.

In such a guide rail 1, since the material thereof is a synthetic resin, there is no need for processing such as removal of distortion or cutting work at the time of manufacture as in the case of steel, and it is possible to manufacture it efficiently at low cost. it can.

Since it is made of synthetic resin, it is much lighter than iron, so that a large amount of guide rails 1 can be efficiently and inexpensively transported and carried to an elevator installation site at one time. For this reason, work such as installation in the hoistway can be easily and efficiently performed.

In the guide rail 1 made of synthetic resin,
A quiet elevator operation can be achieved while suppressing the propagation of vibration and noise when the car or the counterweight travels.

Further, since the material is a synthetic resin, there is no problem of rust, and even in the case of an observatory elevator, the discoloration of the guide rail 1 can be suppressed and a good appearance can be always maintained.

It is also possible to use a colored synthetic resin as a material for the guide rail 1. In this case, the guide rail 1 having a predetermined color can be obtained without applying a coating. When used as the rail 1, a better appearance can be maintained.

Since the guide rail 1 is made of a synthetic resin, the guide rail 1 can be formed into an arbitrary shape. In the guide rail 1 according to the first embodiment shown in FIGS. 1 and 2, the cross-sectional shape of the guide portion 3 is rectangular.
As shown in FIG. 3 as a second embodiment, the cross-sectional shape of the guide portion 3 is triangular, or a circular shape or a star shape (not shown). It is possible to design so as to suppress shaking and vibration.

The guide rail 1 made of synthetic resin is preferably applied to a small elevator for low floors from the viewpoint of strength and abrasion resistance, but as shown in FIG. A guide rail is provided by attaching a metal member 4 such as a steel plate which is high in strength and excellent in wear resistance to a surface of a guide portion 3 which is a portion where a guide member provided on a car or a counter weight comes in contact with the guide portion 3 along its longitudinal direction. It is possible to increase the substantial strength and abrasion resistance of No. 1.

By adopting such means, the invention can be applied not only to a small elevator for a low floor, but also to an elevator for a high floor.

As shown in FIG. 5 as a fourth embodiment, a low-friction material 5 is continuously attached to the surface of the guide portion 3 along the longitudinal direction to improve the smoothness of running of the car and the counterweight. It is possible to increase the ride comfort.

[0026]

According to the first aspect of the present invention, since the guide rail is made of synthetic resin, it is possible to facilitate the manufacture and reduce the weight.

According to the second aspect of the present invention, since the guide rail is made of a colored synthetic resin, the appearance of the guide rail can be enhanced.

According to the third aspect of the present invention, the cross-sectional shape of the guide portion of the guide rail with which the guide member provided on the car or the counterweight comes into contact is made triangular, so that the car or the counterweight rolls. And vibration and the like can be designed.

According to the fourth aspect of the present invention, since the metal member is attached to the guide portion of the guide rail with which the guide member provided on the car or the counterweight contacts, the substantial strength of the guide rail can be increased. it can.

According to the fifth aspect of the present invention, since the low friction material is attached to the guide portion of the guide rail with which the guide member provided on the car or the counterweight comes in contact, the smoothness of the running of the car or the counterweight is improved. Raise the ride comfort.
