Abstract

PROBLEM TO BE SOLVED: To provide a footboard of a passenger conveyor capable of making itself hard to slip on in comparison with a conventional flat tread state even in the case of not only a footboard of a metal thin plate molding type but also a footboard of an aluminum type even when a shoe bottom of a passenger is wet with rain water, etc. SOLUTION: Particulates such as metal particulates, acrylic particulates are fastened on a passenger tread part of the footboard for the passenger conveyor such as an escalator, an electric road, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor device such as an escalator or a moving walkway, and more particularly to a surface structure of a cleat of a tread.

[0002]

2. Description of the Related Art Conventionally, in order to prevent passengers from slipping on a tread such as an escalator or a tread of an electric road, a groove has been cut in a cleat formed on the tread (actually, the number of actual constructions is 50-14.
No. 7394) or a projection (Japanese Utility Model Laid-Open No. 58-117463) provided on the top of the cleat to make the tread less slippery. Also known is one in which a thin metal plate is bent into a continuous corrugation to form a large number of cleats, and an intermittent groove (Japanese Patent Application Laid-Open No. 1-308388) is provided at the top of the cleats so as to be orthogonal to the longitudinal direction thereof. Has been.

[0003]

The above is the conventional passenger conveyor tread, and the tread structure in which the groove is cut in the cleat lowers the strength of the aluminum cleat and is easily damaged. On the other hand, if the projections are provided on the top of the cleat, there is a problem that the projections are damaged or worn. In addition, a thin metal plate is bent into a continuous corrugated shape to form a large number of cleats, and in the case where grooves are provided intermittently so as to be orthogonal to the top and the longitudinal direction of the cleats, in comparison with the case where no groove is processed Although it has the effect of making it less slippery, when the shoe is wet with rainwater or the like and rides on the tread, the frictional resistance is lower than in a dry state, and there is a problem that it becomes slippery.

An object of the present invention is to provide a tread plate for a passenger conveyor that can prevent slipping of a passenger's shoe sole due to rainwater or the like as compared with a conventional flat tread surface.

[0005]

In order to achieve the above object, the present invention is to bend a thin metal plate into a continuous corrugation to form a large number of cleats, and to make the longitudinal direction of these cleats along the traveling direction of passengers. , And particles such as metal particles or acrylic particles are fixed to the top surface of the cleat.

As described above, in a tread plate in which a large number of cleats are formed by bending a thin metal plate into a continuous corrugation, particles of metal or the like are fixed to the tops of the cleats, and therefore the robustness of the tread plate can be maintained as it is. Further, there is an effect that it is less slippery than the conventional flat tread surface.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to a metal thin plate molding type tread plate for an electric road shown in FIGS.

A tread 1 according to an embodiment of the present invention is shown in FIGS.
As described above, the tread plate 2 on which the passenger directly rides, the frame body 3 supporting the tread plate 2, and the wheels 4A and 4B supported by the frame body 3. The length of the tread 2 in the traveling direction is L
200-500mm, width W is 500-1600mm
Then, for example, the metal thin plate 5 made of stainless steel plate is several meters.
A large number of cleats 5 that are continuously bent in a wave pattern at m pitches
A and the groove portion 5B are formed to form the tread plate 2. Further, each cleat 5A and the groove portion 5B are formed parallel to each other and are located along the traveling direction, and all the top portions 5T of the cleat 5A are on the same plane.

FIG. 3 is a cross-sectional view of the cleat which becomes the tread surface of the tread 2, and shows a state in which particles such as metal particles or acrylic particles are fixed to the surface of the cleat 5, as shown in the figure. The method of fixing is to apply it by adhering or mixing it with paint. In addition, in the case of metal, a method of melting and spraying and fixing may be used.

FIG. 4 shows a state in which after coating the surface of the cleat, the coating film on the top of the cleat is removed with a file or the like, and particles such as metal are fixed to the portion where the coating film is removed.

In this manner, particles such as metal are fixed to the cleat, and fine irregularities are formed on the top of the cleat, which is a portion on which passengers ride. is there.

[0012]

As described above, according to the present invention, it is possible to provide a tread plate for a passenger conveyor which is less slippery than the conventional flat tread even when the soles of the passengers get wet due to rainwater or the like. Also, with this configuration, it is possible not only to perform additional processing on the treads in the factory but also to easily deal with the escalator already installed and the treads of the electric road, so only the thin steel plate type treads are available. It can also be used for aluminum type treads.
