Abstract

PURPOSE:To prevent a falling-down accident in the vicinity of a getting-on/off port by changing color on the stepping surface of a stair and the floor surface in the vicinity of a coam and making the area of the colored part of the floor surface equal or more than the stepping surface area of the stair and changing the design arrangement of the fixed parts and shiftable parts. CONSTITUTION:Each stair 2 has a stepping surface 2A consisting of a number of stepping surface top parts 2a in straight line form in the innermost part direction and a stepping surface groove part 2b, and an attention stripe 2c colored in yellow is formed at the front edge of the stepping surface 2A. Then, a coam 6 having a number of tooth tops meshed with the obverse surface part of the stair 2 is formed at a getting-on/off port, and on a getting-on/off floor 7 for preventing the slip of passengers which is colored to yellow and supports the coam 6, a floor surface top part 7a and a floor surface groove part 7b are arranged in a laterally long design on a floor surface 2A. Since the area of the white colored part is nearly equal to the stepping surface 2A of one stair or more and nearly equal to the area where a passenger stands, the color difference from the stair 2 in a movable part can be distinctly confirmed when the passenger stands on the floor surface of the getting-on/off port and sees his feet, and the passenger can confirm his feet and the place when he gets off from the staircase 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an escalator that is a passenger transport vehicle, including an electric road, and particularly relates to an escalator that has been improved near the entrance/exit.

[Conventional technology]

Generally, as shown in Fig. 4, escalators are used while moving from the floorboard 1 of the entrance to the steps 2 and while holding the moving handrail 4 that moves along the upper edge of the handrail 3. However, the safety of passengers is ensured. Various safety devices are provided for this purpose.

This safety device includes, for example, a triangular guard plate 5 for preventing head collisions, and as shown in FIG. It is common to form a tread groove 2b and to provide caution bands 2B and 2C made of synthetic resin colored yellow on both sides and the front end of the tread 2A.

Furthermore, in the entrance area where the steps 2 go in and out, there is a comb 6 with many tooth tips that engage with the surface of the steps 2, and on the floor plate 1 provided to support the comb 6, there is a comb 6 as shown in FIG. To prevent passengers from slipping, a boarding floor LA consisting of a stainless steel or aluminum floor top 1a and a floor groove 1b with a metal-colored surface is arranged. When using an escalator with such a configuration, there are occasional accidents in which the user fails to shift his weight and falls when stepping from the fixed platform 1A to the continuously moving steps 2. The number of accidents is widely known as compiled by the Japan Elevator Association and published in a magazine, and it is one of the most common escalator accidents. In order to prevent such falling accidents near the entrance/exit, there is a known method that clearly defines the interface between the comb and the steps at the entrance, as disclosed in Japanese Utility Model Publication No. 49-34312, for example.

In addition, in order to prevent passengers from stepping on the boundaries between steps and falling when there is a difference between the steps, Japanese Utility Model Application Publication No. 62-203178 changes the color tone of adjacent steps to mark the boundaries. it's shown.

All of these solutions are designed to help elderly people who are prone to falling due to problems with timing and agility when stepping onto steps that move upward or downward. There were safety-oriented measures implemented. In particular, in the case of an escalator, the moving handrail is also moving, so passengers first grasp the moving handrail, and if the transition of their feet is delayed, only their upper body will be pulled, and they may fall. [Problem to be solved by the invention] Conventional escalator fall prevention near the entrance/exit has been carried out as described above, but the former method has been evaluated as having a high safety effect based on its long history of use. However, because the length of the steps in the traveling direction is relatively small, the effect of making passengers aware of the boundaries is weak. It would be more effective if the comb was made longer, but since the comb is made of synthetic resin, it is not possible to make it longer in terms of accuracy and strength. Also, the same color as the comb, e.g. Yellow warning strips are attached to the steps, and some of the moving steps are yellow, making it difficult to distinguish between the fixed and moving parts by color.

On the other hand, according to the conventional latter method, it is possible to clearly mark the boundaries between steps, prevent falls due to differences in steps after stepping on the steps, and yellow caution strips are placed at both the front and rear ends of the steps. Similar effects can be obtained with a known configuration. but,
The painting process during manufacturing was complicated because the steps were alternately colored in different colors, and it was not efficient, as it required color-based management during assembly.

An object of the present invention is to provide an escalator that can improve safety near the entrance/exit.

[Means to solve the problem]

In order to achieve the above object, the present invention has a tread consisting of a large number of peaks and grooves that are connected in an endless manner and are formed linearly in the depth direction, and the front end of the tread has a tread with a paint color different from that of the tread. A step with different caution bands, a comb provided at the entrance for getting on and off the step and having many tooth tips that engage with the surface of the step, and a comb that supports the comb and has a top part of the floor surface and the floor. In an escalator equipped with a boarding floor having a patterned floor surface by combining surface grooves, the paint color of the tread grooves is different from the paint color of the floor surface adjacent to the comb, and The area of the painted colored portion of the floor surface is equal to or larger than the area of the tread surface of one of the steps, and the pattern arrangement consisting of the combination of the floor top and the floor groove is arranged with respect to the direction of movement of the step. It is characterized by being arranged horizontally in the direction perpendicular to the two.

[Effect]

Since the escalator of the present invention has the above-described structure, when passengers get on and off, the paint color of the grooves on the tread and the paint color of the floor grooves are different, and furthermore, the pattern arrangement on the floor is perpendicular to the steps. The difference in color and pattern increases visibility to distinguish between the fixed and movable parts, which in turn helps prevent falls near the entrance/exit. 6 [Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

The overall configuration is almost the same as the conventional one, as shown in Figure 1.
Passengers are transported using a movable handrail 4 that moves along the upper edge of a parapet 3 together with steps 2 that are connected in an endless manner. Each step 2 has a large number of straight tread tops 2a in the depth direction and a tread 2A extending from the tread grooves 2b, and the front end of the tread 2A is colored yellow, unlike the base color of the stainless steel or aluminum tread. Please note that there is a $2C charge. At the entrance, there is a comb 6 with many teeth that engages with the surface of the steps 2, and this is also colored yellow. The boarding floor 7 that supports the comb 6 and prevents passengers from slipping has a floor top 7a and a floor groove 7b arranged in a horizontally long pattern on its floor 7A, as will be described later.

FIG. 2 shows a tread surface 2A of the step 2, and the tread surface 2A has a large number of tread tops 2a formed linearly along the depth direction, that is, the direction of travel, and tread grooves 2b alternately shaped as shown in the figure. It's intimidating. The tread neck portion 2a is made of stainless steel or the same color as the base color of aluminum, while the tread groove portion 2b is made of stainless steel or aluminum.
has a black paint color. The depth dimension of this tread 2A is about 400 m, and the width in the width direction is about 800 books for a single person, and about 1000 m for a two person person.

FIG. 3 shows an enlarged view of the floor surface 7A of the boarding floor 7, in which the tread surface 2A of the step 2 is located adjacent to the comb 6 in the floor groove portion 7b.
Areas equal to or larger than the area are whitish beige color, more specifically Munsell symbol 7.5YR7.5/L.
It has a similar paint color. Furthermore, the pattern arrangement consisting of the combination of the floor surface top part 7a and the floor surface groove part 7b of the floor surface 7A is as follows.
For example, for the total dimension L of three floor tops 7a and two floor grooves 7b (width Ua) between them, the adjacent floor groove 7B should be made wider (width Q>12a) L, and the overall width should be increased. It is a collection of patterns that appear to be perpendicular to the direction. Here, the area of the whitish painted part is about the same as or larger than the tread 2A of one step, and is about the same area as the passenger stands on, so the passenger can stand on the floor of the entrance and exit. When you look at it, you can clearly recognize the color difference between the movable part and the step 2, and even when you get off the step 2, you can visually check your feet and confirm the foothold. In addition, since the pattern arrangement on the floor surface 7a is perpendicular to the traveling direction of the steps 2 and arranged linearly in the width direction of the escalator, it is completely different from the surface pattern of the steps 2, which also makes a difference in visual perception for passengers. This has the effect of making people recognize the fixed part and the movable part. Note that the shape of the floor top 7a is not limited to the square shown in the example, but may be round or triangular, as long as it has a horizontally long pattern arrangement as described above.

In this embodiment, part of the steps 2 is black, the comb 6 is yellow, and part of the floor 7A is whitish, so there is a clear difference in brightness and color between them. In addition, since there are gradients in brightness, color difference, and changes in pattern along this path, it is possible to confirm the footing involved when getting on and off at the entrance.

The inventors conducted a monitoring survey using an actual escalator. At this time, the tread groove 2b of the step 2 is black, the caution band 2C is yellow, the color of the comb 6 is yellow or the same color as the floor, and the painted color of the floor groove 7b is the tread 2A,
And beige, which is clearly different from the paint color of comb 6,
i! The four colors of brown, green, and gray! ! In preparation, the average age was 67.4 years old, and 7 men and women each had different color conditions for ascending or descending operations. ) I asked about the color of the boarding floor. The results are shown below, and it was found to be effective in preventing elderly people from falling near entrances and exits.

In the above embodiment, the tread groove portion 2b of the tread surface 2A is made of black color,
In addition, although the floor groove portion 7b is colored beige or the like, the color may be selected arbitrarily as long as there is a clear difference in brightness or color.

〔Effect of the invention〕

According to the present invention, the color of the tread of the step, which is a movable part, and the floor surface near the comb, which is a fixed part, is changed, and the painted color part of the floor surface is made equal to or larger than the area of the tread of one step. By changing the pattern arrangement of the fixed part and the movable part, visibility due to the color difference and pattern is improved, and it is possible to prevent accidents of falling near the entrance/exit.
