Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger carrier such as an escalator, and in particular, is formed between a moving handrail moving in an ascending direction and a fixed object such as a building ceiling adjacent to the moving handrail. The present invention relates to a configuration of safety equipment arranged in a wedge-shaped space.

[0002]

2. Description of the Related Art Generally, a moving handrail moving in a rising direction of a passenger carrier (such as an escalator) and a fixed object (an obstacle such as a building ceiling) adjacent to the moving handrail are located between the moving handrail and the fixed handrail.
Safety equipment, commonly called a synthetic resin triangular guard plate, is provided, and measures are taken to prevent passengers (heads) who have leaned far outside the moving handrail from being pinched and accidents. As an example, a combination system of a first safety facility (fixed type) and a second safety facility (oscillating type) disclosed in Japanese Patent Application Laid-Open No. 10-139346 is known.

[0003]

The safety equipment for a passenger carrier having the above-mentioned structure is characterized in that the first and second safety equipment located at the front and the rear of the wedge-shaped space except for a part thereof move between the moving handrail. Has vertical surfaces separated by a horizontal distance equal to
If the passenger's head enters between the oscillating second safety equipment and the moving handrail, the second safety equipment is displaced, and then the horizontal distance between the fixed first safety equipment and the moving handrail. There is a concern that they may enter and be trapped inside the building, leading to an accident. in this case,
The penetrating head is caught in the small horizontal distance gap of the first safety equipment fixed suddenly from the horizontal distance of the second safety equipment, which is enlarged by swinging, which means that the head is caught with the movement of the passenger. The problem is that they are in an arrangement that makes them easy to handle.

[0004] It is an object of the present invention to provide a safety device for a passenger carrier in which a horizontal distance between a moving handrail and each safety device functions on the safe side for the passenger.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is installed at an angle between a lower floor and an upper floor,
A first safety device is provided at a front portion of a wedge-shaped space formed between a passenger carrier having a moving step and a moving handrail and a fixed object such as another passenger carrier adjacent to the moving handrail. The second safety equipment is arranged at a rear portion of the vehicle at a horizontal distance from the moving handrail, and the second safety equipment is disposed at a distance from the front edge of the first safety equipment to the horizontal distance between the moving handrail. The horizontal distance between the front edge of the equipment and the moving handrail was arranged to be large.

As described above, the horizontal distance between the front edge of the first safety equipment located at the front (corresponding to the second safety equipment of the prior art) and the moving handrail is the second safety equipment located at the rear. A state in which the horizontal distance between the leading edge of the safety equipment (corresponding to the first safety equipment of the conventional example) and the moving handrail is large, that is, the range in which the passenger's head whose horizontal distance is moving is small to large. The head, which may be pinched, notices the existence of the first safety equipment in the range of small distance, and even if it moves in the state of being pinched, the head moves to the area of large distance Therefore, the head is not strongly pinched at the second safety equipment. For this reason, the first and second safety equipment
The horizontal distance (spacing) acting on the safety side is maintained, contributing to increased safety.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to an escalator which is a passenger carrier shown in FIGS.

The escalator 1 according to the present invention is configured as follows. That is, as shown in FIG. 1, the escalator 1 which moves in the ascending direction is installed with its main body inclined between the lower and upper floors with a difference in elevation, and the moving escalator 2 for moving passengers and the moving handrail 3 are provided. On the other hand, a wedge-shaped space Q formed between a fixed object 4 such as a building ceiling FF of an upper floor F adjacent to the moving handrail 3 is suspended by a chain K at the front (lower side). The first safety equipment 5, which is an approximately triangular plate for alerting and made swingable, is fixed to the fixed object 4 with screws B at the rear (upper side), and the passenger's head is connected to the building ceiling FF etc. The height h (about 200 m) that is not sandwiched between the moving handrail 3
m), a second safety facility 6 of a substantially triangular plate for accident prevention, which is secured and closed.

Here, each of the safety equipments 5 and 6 is shown in FIG.
As shown in FIG. 2 which is a cross-sectional view along the line A,
The outer edge 3 of the moving handrail 3 is located at a distance W1, which is the horizontal distance between the outer edge 3A of the first safety equipment 5 and the front edge 5A having the diameter d1 of the first safety equipment 5.
The distance W2, which is the horizontal distance between A and the front edge 6A having the diameter d2 of the second safety equipment 6, is larger (W1 <W2). In this case, the difference between the intervals W1 and W2 is
A and the front edge 6A are formed by a difference in diameter (d1> d2). In this case, the substantially triangular plate 5a of the first safety equipment 5 and the substantially triangular plate 6a of the second safety equipment 6 are formed. The space W3 with the moving handrail 3 is arranged equally.

[0010] When the passenger on the moving step 2 leans heavily and rises, and the head reaches the space W1 at first, the feeling of contact of the head with the first safety equipment 5 causes the body to feel uncomfortable. Although the reflection operation is started to return the (head), even if this operation is slightly delayed and the head reaches the second safety equipment 6, the interval W2 is larger than the interval W1. The phenomenon of being strongly pinched by the vehicle is avoided, and it functions on the safe side for passengers.

FIG. 3 shows a first safety equipment 5 different from the above.
FIG. 2 shows an arrangement in which the distance Wb between the second safety equipment 66 and the moving handrail 3 is suspended and fixed in a state where the distance Wb between the second safety equipment 66 and the moving handrail 3 is larger than the distance Wa between the moving handrail 3 and FIG. Will function on the safe side as well.

Here, the difference between the distances W1 and W2, the distance Wa,
The difference in Wb can also be realized by making the thickness of the substantially triangular plate body (reference numerals 5a, 6a, etc.) itself large or small, irrespective of the configuration of FIGS.

Each of the safety equipment in the above embodiment can be applied to a moving sidewalk which is a passenger transporter like the escalator 1, and the material of each safety equipment is lightweight and has good strength, workability and colorability. A polycarbonate resin or an acrylic resin is used.

[0014]

According to the present invention, it is possible to provide a passenger transporting safety facility in which the horizontal distance between the moving handrail and each safety facility acts on the safety side for the passenger.
