Abstract

PROBLEM TO BE SOLVED: To provide an outdoor passenger conveyer capable of keeping the surface of a handrail within a designated temperature range by automatically cooling the surface of the handrail when the temperature of the handrail surface reaches a designated temperature or higher. SOLUTION: This outdoor passenger conveyer having the handrail 3 exposed to the outdoor, is provided with a cooling device 5 for cooling the surface of the handrail 3, and a temperature switch 6 for inhibiting the operation of the cooling device 5 when the temperature of the handrail 3 surface does not reach a designated temperature or higher, and operating the cooling device 5 when the temperature of the handrail 3 surface reaches a designated temperature or higher.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an escalator,
The present invention relates to a passenger conveyor such as a moving road, and particularly to an outdoor passenger conveyor in which a handrail is exposed at least outdoors.

[0002]

2. Description of the Related Art Conventionally, in an outdoor passenger conveyor which is installed outdoors and has at least a handrail exposed outdoors, in the middle of summer, the handrail is heated by sunlight and the surface of the handrail is heated. Temperature often reached about 55 ° C. or higher.

[0003]

In the conventional outdoor passenger conveyor described above, the temperature of the surface of the handrail becomes about 55 ° C. or higher, so that it is difficult for the passenger to grasp the handrail. Was. Therefore, especially in the middle of summer, passengers use the outdoor passenger conveyor while standing on the tread surface without grasping the handrail, and there is a safety problem.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide an outdoor passenger conveyor having a simple structure capable of automatically cooling the surface of a handrail so that it is not difficult for a passenger to grip the handrail. To provide.

[0005]

The object of the present invention is to provide a cooling device for cooling a surface of a handrail in an outdoor passenger conveyor in which at least the handrail is exposed outdoors;
A temperature switch that does not operate the cooling device when the temperature of the surface of the handrail does not reach a predetermined temperature or higher, and that operates the cooling device when the temperature of the surface of the handrail reaches a predetermined temperature or higher. It is achieved by becoming.

According to this configuration, when the temperature of the surface of the handrail reaches a temperature at which it becomes difficult to grip the handrail, that is, when the temperature reaches a predetermined temperature or higher, the cooling device can be operated without any operation by maintenance personnel. A temperature switch activates automatically to cool the surface of the handrail. Further, when the temperature of the surface of the handrail becomes lower than the predetermined temperature, the cooling device is automatically stopped by the temperature switch without any operation by the maintenance personnel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, an outdoor passenger conveyor 1 comprises:
It has a plurality of treads 2 connected endlessly, handrails 3 provided on both left and right sides of the treads 2, and a truss-type frame 4 supporting the handrails 3 and the treads 2. are doing. The outdoor passenger conveyor 1 includes a cooling device 5 for cooling the surface of the handrail 3 and a handrail 3
As long as the surface temperature does not reach a predetermined temperature or higher, the cooling device 5
And a temperature switch 6 that activates the cooling device 5 when the temperature of the surface of the handrail 3 reaches a predetermined temperature or higher without operating the power switch 3.

As shown in FIG. 2, the cooling device 5 comprises an alcohol spraying device 7 for spraying alcohol on the surface of the handrail 3 and a fan device 8 for promoting the vaporization of the alcohol sprayed on the surface of the handrail 3. . The alcohol spraying device 7 includes an alcohol tank 7A and a compressor 7
B and the first for guiding compressed air from the compressor 7B to the nozzle 7C.
A hose 7D and a second hose 7E for guiding alcohol from the alcohol tank 7A to the nozzle 7C are provided.
The alcohol guided to the nozzle 7C is formed into a mist at the tip of the nozzle 7C and is sprayed on the surface of the handrail 3 by the action of compressed air.

As shown in FIG. 1, the temperature switches 6, 6A are provided at the entrance of the upper machine room of the passenger conveyor 1 and at the entrance of the lower machine room of the passenger conveyor 1, respectively. 3, the surface temperature is above a predetermined temperature,
For example, it is electrically connected to the alcohol spraying device 7B so as to operate at a temperature of 40 ° C. to operate the alcohol spraying device 7B of the cooling device 5. As shown in FIG. 2, the fan device 8 is disposed on the left and right sides of the nozzle 7 </ b> C.
It sprays on the surface. The fan device 8
There is a sirocco fan structure.

In the above configuration, when the passenger conveyor 1 is running up, the temperature switch 6 is excited,
The cooling device 5 and the fan device 8A are operated. Further, when the passenger conveyor 1 is operating down, the temperature switch 6A is excited, and the cooling device 5 and the fan device 8 are operated. When the cooling device 5 and the fan device 8 or the fan device 8A operate, the surface of the handrail 3 is cooled, and the surface temperature is rapidly increased.
The temperature is reduced to a temperature at which a passenger can comfortably grip the handrail 3.

[0012]

As described above, according to the present invention, without any operation by maintenance personnel, the temperature of the surface of the handrail is automatically adjusted before reaching the temperature at which it becomes difficult to grasp the handrail. Then, cool the surface of the handrail,
Since the passenger can grip the handrail even in, for example, midsummer or the like, an easy-to-handle outdoor passenger conveyor that allows the passenger to ride on the tread safely can be obtained.
