Abstract

PROBLEM TO BE SOLVED: To prevent the reduction of a friction force even if rain or dew condensation occurs by providing a belt for increasing a friction force in a contact surface with the driving roller of a canvas section. SOLUTION: A handrail 1 is composed of a canvas section 2, dressing rubber 3 for covering the canvas section 2 and a belt 4 provided in a part contacted with the driving roller of the canvas section 2 for increasing a friction force. For the belt 4, polyflex rubber having recessed and projecting parts in the front face is most suitable. Because of the belt 4, no reduction occurs in a friction force even if rain or dew condensation occurs, and no problems occur in dividing of the handrail 1. Also, since there are recessed and projecting parts on the surface because of the polyflex rubber, a friction force is increased and driving is assured more.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail used for an escalator and an electric road.

[0002]

2. Description of the Related Art Generally, handrails are disclosed in
As shown in Japanese Patent No. 8573, it is composed of a canvas portion and a decorative rubber covering the outer surface of the canvas portion. In this handrail, the canvas portion and the decorative rubber are pressed and driven by a driving roller so that the upper part of the balustrade usually moves in synchronization with the steps.

[0003]

In particular, in the case of an outdoor escalator, there is a problem that the frictional force between the canvas portion and the drive roller is reduced due to rain or dew, and the handrail cannot be driven.

[0004] An object of the present invention is to provide a handrail that can prevent a reduction in frictional force.

[0005]

The object of the present invention is to provide a canvas part,
In the handrail made of decorative rubber covering the outer surface of the canvas portion, a belt for increasing frictional force is provided on a contact surface of the canvas portion with a driving roller.

Further, the belt is a polyflex belt.

Since a belt for increasing the frictional force is provided on the contact surface of the canvas portion with the driving roller, the frictional force does not decrease even if rain or dew occurs, and the problem that the handrail cannot be driven does not occur. Absent.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a perspective view showing a handrail according to an embodiment of the present invention.

Reference numeral 1 denotes a handrail.
Is composed of a canvas portion 2, a decorative rubber 3 covering the canvas portion 2, and a belt 4 for increasing frictional force provided at a portion of the canvas portion 2 which comes into contact with a driving roller (not shown). As the belt 4, a polyflex belt having unevenness on the front is optimal.

According to this embodiment, since the belt 4 is provided, the frictional force does not decrease even if rain or dew occurs, and there is no problem in driving the handrail 1. Further, in the case of a polyflex belt, since the surface has irregularities, the frictional force increases, and more reliable driving can be performed.

[0011]

As described above, according to the present invention, since the belt for increasing the frictional force is provided on the contact surface of the canvas portion with the drive roller, the frictional force does not decrease even if rain or dew occurs. ,
There is no problem that the handrail cannot be driven.
