Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to safety equipment for passenger conveyors such as escalators and motorized roads.

[Conventional technology]

BACKGROUND ART Conventionally, there have been some accidents in which passengers who lean outward from the steps of a passenger conveyor collide with the ceiling of a building adjacent to the side of the passenger conveyor and are injured.

As a countermeasure against this problem, it is common to provide safety equipment as disclosed in Japanese Utility Model Application Publication No. 51-66992.

As schematically shown in Figure 3, this safety equipment is installed under the conditions that the building ceiling T is close to the outside of the step 1 and the handrail 2, which are connected in an endless manner and move, and the HT-3 that guides and supports the handrail 2. Below, in order to prevent passengers M who are leaning heavily from this handrail 2 from colliding their heads Ma with the lower side surface t of the ceiling, a roughly triangular protector 5 is suspended by chains 4. This alerts you that a triangular intersection is near.

[Problem to be solved by the invention]

In the passenger conveyor equipped with the conventional safety equipment described above, the third
As shown in the figure, the passenger M, whose head Ma is facing extremely downward, pushes the protector 5 outward, resulting in a diagonally shaded circle Z.
There have been cases where the handrail has been caught between the lower side sill and the handrail 2 in a situation like this, and improvements to this phenomenon have been desired. The condition in which the head Ma is pinched is the worst when the minimum distance Wa shown in FIG. 3 is used, and when the distance is wide like W, the installation condition is on the safe side.

An object of the present invention is to improve safety by eliminating the condition that pinches the head Ma, and to provide a more reliable mounting structure.

[Means to solve the problem]

The above purpose is to provide a first protector that is provided on the starting point side of the triangular part formed by the side lower part t of the ceiling and the handrail 2, and supported by a guide rail that is installed in the UIA on the ceiling of the building;
This first protection body is achieved by configuring the safety equipment with a second protection body that is spaced at a constant interval in the longitudinal direction of the passenger conveyor and suspended from the ceiling of the building.

[Effect]

The first protector prevents the head Ma from entering the starting point side of the most dangerous triangular intersection, and the second protector in the front prevents the passenger from leaning out in a dangerous place. Let me know what's coming soon. In addition, the first protector is supported by a guide rail fixed to the ceiling of the building, ensuring its mounting strength, and has the function of moving slightly in the direction of travel of the passenger conveyor to provide cushioning when it receives a collision force. There is. This ensures safety and strength.

〔Example〕

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

In Figures 1 and 2, step 1, handrail 2
, the parapet 3, the building ceiling T (side lower part), etc. are the same as the conventional ones, but in the present invention, the building ceiling T is placed at a small distance ΩL on the starting point S side of the triangular intersection Q. A guide rail 7 is provided which is fixed with screws 6, and a first protector 8 having a length Q2 whose upper end is supported by the guide rail 7 is provided. A second protector 11 with a length Q4 is installed on the building ceiling T with a fixture 9 and a chain 10, and a guide rail 7,
Safety equipment 12 with first protector 8, second protector 11, etc.
It is characterized by its composition.

In this case, the upper end of the first protector 8 is attached to the hollow part 7a of the guide rail 7, so that it can move slightly as shown by the arrow "X" when a human body such as the head Ma collides with the first protector 8. In addition, Ql and Q3 are approximately 100+n+n, 92, Q
+ is set to about 300 to 1000 nun, and it is convenient that the material is made of a transparent acrylic plate or the like that does not block the passenger's view.

Here, as shown in FIG. 3, if the passenger M who has lowered his/her head Ma extremely lowers the head Ma and passes by pushing aside the second protector 11, the head Ma will be lowered to the second protector. It collides with the front i8a, but is buffered by the movement of the arrow Further progress is prevented. Therefore, the head Ma is not pinched as shown in FIG. 3 (Z), and the second protector 11 provides an attention-calling effect, and the guide rail 7 provides strength and cushioning effects.

〔Effect of the invention〕

According to the present invention, it is possible to provide safety equipment for a passenger conveyor that improves passenger safety and has a more reliable mounting structure.

Claims (1)

[Scope of Claims] 1. A step that moves in an endlessly connected manner, a handrail that moves in synchronization with the step, and a handrail that guides and supports the handrail, and is located approximately at the triangular intersection between the passenger conveyor and the ceiling of the building. In the passenger conveyor safety equipment provided with a triangular protector, the protector is provided on the starting point side of the triangular intersection and is a first protector supported by a guide rail fixed to the ceiling of the building. Safety equipment for a passenger conveyor, characterized in that it is comprised of the first protector and a second protector suspended from the ceiling of the building at a constant interval in the longitudinal direction of the passenger conveyor.
