Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a passenger conveyor that transports people by running on a horizontal or gentle slope, and in particular to a footboard of a passenger conveyor that prevents passengers from falling on the footboard. Regarding.

[Background of the invention]

There are generally two types of passenger conveyors: escalators, which run in a stepped manner, and motorized roads, which run on a gentle slope.The advantages of each are utilized in transportation services.

Gently inclined passenger conveyors have been widely used in stations, airports, exhibition halls, etc., but recently they have also been introduced into shopping centers where they are used for shopping carts, transporting luggage, etc. . This passenger conveyor consists of the passageways shown in Figures 2 and 3, rotating bodies such as the endlessly arranged treads 1 and rails 2, and guides used for guiding and driving (1). Rail 3, drive vehicle 4, handrail 5 supporting the handrail 2, floorboard 6 at the entrance/exit, comb 7
All of these are supported by a sturdy ball frame 8, and the entire structure is mounted under the floor of the building.

Here, the detailed structure of the footboard 1 will be explained.

The tread 1 runs on the guide rail 3 with a roller 9 that moves around, and when it reaches the exit floor plate 6, it precisely engages with the comb 7 at the part indicated by the symbol Z in FIG. Designed to prevent feet from getting caught. For this reason, the upper surface of the footboard 1 has an uneven surface composed of a top portion 1a and a groove portion 1b, as shown in FIG. In addition, the tread l
is usually constructed of a metal body made by die-casting aluminum alloy or bending stainless steel plate, but since the top 1a is only a few millimeters thin, there is a problem of breakage as shown by the symbol Y. This is a situation that occurs frequently.

In the above-mentioned passenger conveyors, especially those with a gentle slope such as slides, passengers have occasionally slipped and fallen on the top surface of the tread l, and a countermeasure is desired. This falling phenomenon was caused by the passengers' carelessness, such as not holding the Nordrail 2 correctly or rushing ahead, but as a transportation facility with a strong public nature, we are taking measures to deal with these problems. is beginning to be requested.

Conventionally, the following two methods have been considered as measures to prevent slippage. One of them is to add a groove for direct firing in the direction of travel of the through treadle 1, indicated by the imaginary line X in FIG. 4, but in this case, the groove weakens the strength of the top 1a, This leaves the problem of promoting the damage phenomenon shown in . There are other proposals, such as the example in the publication of Utility Model Application Publication No. 57-188772, in which a protrusion is provided at the top of the tread, but this method has difficulties in manufacturing and has not been put to practical use. do not have.

Next, an example in which a protrusion is provided will be described as a commonly considered example. The protrusion will be temporarily referred to as a protrusion Q, and this configuration will be explained with reference to FIG. 5, which conceptually shows this structure. Now floorboard 6
Assume that the feet A and shoes Kt of a passenger who does not want to get off even after reaching . In this case, there is no problem at the moment when the relationship between the comb 7 and the treadle 1 is indicated by the solid line in FIG. It can be seen that a situation occurs in which the shoe K (size L) is pinched between the convex portion Q and the comb 7. This pinching phenomenon occurs because the convex part Q is too high and also because the comb 7 forms a convex part structurally. Passengers who are not attentive often encounter this phenomenon. This will cause you to fall.

Therefore, it can be said that the above two proposals still have problems in terms of strength or in the absence of recognition of the pinching phenomenon.

[Purpose of the invention]

In view of the above points, the present invention has been made primarily to improve the tread surface of a gently inclined passenger conveyor to provide a passenger conveyor that is less slippery and free from falling accidents.

[Summary of the invention]

The present invention coats the top of the treads of a passenger conveyor with a paint that has a high coefficient of friction and has an anti-slip effect, thereby preventing accidents such as slipping and falling on the treads, while eliminating the damage troubles mentioned above. Moreover, it is a safe stepping board for a passenger conveyor that does not cause any pinching phenomenon at the exit.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on FIG.

In Fig. 1, the overall structure and main structure of the passenger conveyor explained in Figs. 2 to 5 are approximately the same as the conventional one, but in the present invention, a coating having an anti-slip effect is applied to the top of the tread. There are characteristics.

Here, the treadle 10 according to the present invention is equipped with rollers (not shown) and runs on a guide rail, and has the same structure as the conventional one that engages with a comb at the entrance/exit. Paint 10A with excellent stopping effect
is applied. The paint 10A is made of epoxy, acrylic, or other paint that has excellent adhesion to the treadle 10 and is highly durable, and is also mixed with aggregate 10B such as silica sand to enhance the anti-slip effect. There is. By mixing this aggregate 10B', the surface finish becomes highly uneven, so-called rough, and a high coefficient of friction can be obtained.

By doing this, the sole of the shoe is prevented from slipping on the footboard 10, and the passenger can be prevented from slipping off.

Note that the color tone of the paint 10A may be made to be yellow or red to make it more conspicuous, so as to attract attention or reduce the design effect.

〔Effect of the invention〕

According to the present invention described above, there is an effect of preventing a passenger from falling even in a gentle slope type manconopair. In addition,
Compared to conventional proposals, this method has the advantage of eliminating damage to the tread and the pinching phenomenon at the exit, since no grooves or protrusions are provided at the top of the tread.

In the above description, a gently inclined type passenger conveyor was exemplified, but the present invention is not limited to this, and similar effects can be achieved with a horizontal type or a set of escalator type passenger conveyor.
