Abstract

PURPOSE:To improve the safety of a passenger by forming an inclination angle for generating a necessary step difference between the contiguous staircases at a landing, on a guide rail at the landing. CONSTITUTION:Inside a landing 14, a pair of guiding rails 5 and 6 for guiding the front and rear wheels 2a and 2b of a staircase 2 are arranged. At the same time, a pair of guide rails 5 and 6 are inclined by an angle theta in the vertical direction, and a step difference is generated between a plurality of contiguous staircases 2 at the landing 14. Accordingly, the passengers who are transported to the mean landing through ascent and descent can know in visual and touch form that the mean landing 14 is not a getting-off port, from the variation of the step difference B between the contiguous staircases 2 and the height of a shifting handrail 4, and the restriction for foot stepping-on can be expected, and the turning-down on the basis of misunderstanding can be surely prevented. Further, the discomfortable feeling of the passenger who lowers from a high place and whose view field is shut out can be eliminated, and the designing consistency with the staircase having the landing and the designing performance due to accent can be improved without fail.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an escalator device, and more particularly to an improvement in the structure of an escalator with a horizontal intermediate landing.

[Conventional technology]

An escalator is a device that circulates a large number of steps to transport people and luggage up or down a floor, and generally has a main frame that is tilted vertically.

However, if the main frame is slanted, there is a risk that the view from a high place will be obstructed when driving downhill, putting psychological pressure on the passengers, and the design does not match with the attached staircase with a landing. There were things I didn't do. Furthermore, if the main frame is simply inclined, it is not possible to improve the design.

Therefore, Japanese Patent Application Publication No. 48-7483 and Utility Model Publication No. 56-10
Publication No. 780 and the like propose an escalator with an intermediate landing provided with a horizontal intermediate landing in an attempt to correct the above-mentioned disadvantages.

Figures 3 to 5 show a conventional escalator with an intermediate landing. In the figure, (1) is a main frame that is the main body of the escalator, and this main frame (1) has a vertically inclined intermediate part (
11), an upper end part (12) which is provided horizontally at the upper end of this intermediate part (11) and acts as a landing entrance or an exit gate, and an upper end part (12) which is provided horizontally at the lower end of this intermediate part (11) and which acts as a landing entrance or exit. The lower end part (13) functions as a sprue or a riding sprue, and a landing (14) provided horizontally in the center of the intermediate part (U), inside which a guide rail (not shown) is provided. are arranged in an endless manner (see Figure 3).

(2) is a large number of steps (12) connected and disposed within the main frame (1), and these many steps (12) are guided by the guide rails and moved in circulation based on the drive of a drive device (not shown). The main frame (1) has the function of transporting loaded people, cargo, etc. in the longitudinal direction. At the landing (14), the fifth
As shown by the arrow in the figure, it is designed to move horizontally without creating a step.

(3) are handrails erected on both sides of the main frame (1),
As shown in Fig. 4, endless moving handrails (4) are wound around the plurality of handrails (3) that follow the shape of the main frame (1). , is designed to circulate in synchronization with the large number of steps (2).

At the landing (14), as shown in FIG. 5, it moves horizontally.

However, since the escalator with an intermediate landing has the above-mentioned configuration, it is possible to: ■ surely eliminate the discomfort of passengers whose view is obstructed from a high place, and ■ improve the design consistency with the stairs with a landing. It is possible to achieve a significant improvement in design quality and ■accents.

(Problem to be solved by the invention) However, the conventional escalator with an intermediate landing is
This created a problem in terms of ensuring passenger safety, as it gave passengers the illusion that the landing (14) was actually the exit.

In other words, passengers who are accustomed to riding a normal escalator without a horizontal landing may ride the landing (14) of an escalator with a landing.
), the steps (2) move horizontally from there, so you mistakenly think you have reached the exit and unconsciously take a step. However, in reality, the step (2) moves from horizontal movement to ascending or descending again to move in a stair-like manner, so the passenger hastily places his or her foot on the step between the steps (2). This caused me to fall.

Recently, package carts and shopping carts that can be used on escalators have been placed at airports, shopping centers, etc.
If you mistook 14) for the exit and tried to push the cart forward, the bump would appear again, putting you at risk of falling or colliding with the passenger in front of you.

The present invention has been made in view of the above, and it is an object of the present invention to provide an escalator with an intermediate landing that can significantly improve passenger safety without sacrificing the three advantages mentioned above.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a guide rail that is installed inside the main body of an escalator equipped with a large number of circulating steps and guides the large number of steps in the longitudinal direction of the main body. and,
A parapet that is erected on both sides of the main body and guides a movable handrail that circulates and moves, and a landing that is provided horizontally at an inclined intermediate part of the main body and that horizontally moves the steps and the movable handrail, the guide at the landing. A feature is that the rail is formed with an inclination angle that creates a required step difference between adjacent steps on the landing.

[Effect]

According to the present invention, since the guide rail at the landing is formed with an inclination angle that creates a required step difference between adjacent steps on the landing, the safety of passengers can be significantly improved.

〔Example〕

Hereinafter, the present invention will be described in detail based on one embodiment shown in FIGS. 1 and 2. In the figures, (14) is the middle part (1) of the main frame (1)
This is a horizontal landing in the middle of the landing (11).
4) includes a pair of front wheel guide rails (5) that guide the front wheels (2a) of the steps (2), and a pair of front wheel guide rails (5) that guide the front wheels (2a) of the steps (2).
A pair of rear wheel guide rails (6) for guiding the rear wheels (2b) are provided respectively, and these pair of guide rails (5
), (6) are tilted by θ° in the vertical direction, and a step (
13) occurs (see Figure 1).

In addition, on both sides of the landing (14), parapets (3) are erected along the shape of the main frame (1), and the plurality of parapets (3)
) are each wrapped around a movable handrail (4) that moves in circulation, and the distance H2·) Is (see Figure 1) from the movable handrail (4) to the top of the step (2) at this landing (14) is )+3>82, and the height of the moving handrail (4) held by the passenger changes at the landing (14).

Therefore, the above θ0 needs to be kept as small as possible.

As shown in FIG. 1, this inclination angle θ° is determined based on the depth dimension (A) of the step (2) within a range that does not give a sense of discomfort to passengers. That is, since the depth dimension (A) of the steps (2) is usually about 400 mm, the difference in level of each step (2) (
13) is set between 5mm and 35mm, θ=0.7°
~5°, and if we temporarily set the length of the landing (14) to 1.5
If m and θ=5°, H3-H2=130
The change is approximately +nm. In normal use, there is a step (1
3) is recommended to be set to about 10 mm. In this case, θ = 1.4°, and even if the length of the landing (14) is 3 m, it will only take 13-12 = 70 aun. 4) There is no need to make the passengers who carry the bag feel uncomfortable.

In addition, it is desirable that the distances H1 and H4 from the moving handrail (4) to the top of the step (2) on the inclined part of the parapet (3) be set to the same dimension (see FIG. 1).

Therefore, passengers who have ascended or descended to the landing (14) and have been transported will be affected by the height difference (B) between the adjacent steps (2) and the change in the height of the moving handrail (4). Since the person knows visually and tactilely that it is not the mouth, it is expected that the person will be able to refrain from stepping forward, and it will be possible to reliably prevent falls due to misunderstanding. Since the landing (14) itself is provided horizontally as in the conventional example, ■ it definitely eliminates the discomfort of passengers whose view from high places is obstructed, and ■ it is consistent in design with the staircase with landing. This does not impair the advantages of a significant improvement in appearance and designability due to accents.

〔Effect of the invention〕

As described above, according to the present invention, the guide rail at the landing is formed with an inclination angle that creates a required step difference between adjacent steps on the landing, so that the safety of passengers is significantly improved and the It is possible to provide an escalator with an intermediate landing that can reliably maintain the advantages.
