A moving handrail provided at the upper end on both sides of the moving handrail and moving in the ascending direction, and a fixed object (obstacle) located close to the moving handrail
It is known that a safety device commonly known as a synthetic resin triangular guard plate is provided between them, and measures are taken to prevent the passenger from climbing out of the moving handrail from getting caught in the head. Have been. In the old example,
Japanese Patent Laid-Open No. 10-139346 discloses, in a recent example, a first safety facility (fixed type) and a second safety facility (fixed type) disclosed in Japanese Patent Application Laid-Open No. 10-139346. (Swinging type) There is a compound type additional safety guidance means.

[0003]

In the above-mentioned conventional safety equipment, when the head or baggage of a passenger moving in the ascending direction collides strongly, the main plate of the safety equipment is joined to its front edge. As a result, excessive stress is generated at the boundary of the part, and the main plate is damaged. In addition, there has been a problem that the broken pieces become blade-shaped and cause harm to the head that collides with the broken pieces. In addition, when a passenger who is uncertain at the upper and lower ends of the cylindrical front edge opens paper debris or dust adheres to the inner peripheral wall due to static electricity, it is difficult to remove the dust because of the cylindrical body. There were also design issues. However, in both of the above-mentioned known examples, there is no countermeasure against these problems, and they have been regarded as important issues in terms of passenger protection and design.

The present invention has been made in order to solve such a problem. A passenger moving in a rising direction by a passenger transporter has a moving handrail and a fixed object which approaches the moving handrail to form a wedge-shaped space. It is an object of the present invention to obtain a configuration in which the safety equipment is less likely to be damaged and has excellent design properties when it collides with safety equipment provided between the safety equipment.

[0005]

In order to achieve this object, the present invention relates to a passenger transporter which is installed at an angle between upper and lower floors having a difference in elevation, and a passenger transporter provided at both upper ends of the passenger transporter. The moving handrail provided and located close to the moving handrail,
In a device provided with a substantially triangular-shaped safety device which is mounted in a suspended state in a wedge-shaped space with a fixed object having a different inclination angle from the moving handrail, the safety device includes a substantially triangular main plate body, It is formed of a cylindrical vertical front edge joined to the front edge of the main plate, a closing body closing the upper and lower ends of the front edge, and an upper edge joined to the upper edge of the main plate. On the other hand, the main plate body is characterized in that three bodies of a leading edge body and an upper edge body are joined by joining means.

[0006]

With this construction, the passenger transport safety equipment of the present invention is joined to the substantially triangular main plate and the front edge of the main plate, and the cylindrical opening is closed by the closing body. The main plate, the front edge and the upper edge are joined by joining means, while the main plate is formed by the separated leading edge and the upper edge joined to the upper edge of the main plate. Even in the event of a strong collision force of the passenger's head or baggage, it exerts the role of reinforcing the edges of the main plate and increases the overall strength, and produces the highest stress (causing damage) Breakage is prevented by the three-piece joint starting end being superposed and formed by the three bodies. In addition, since the upper and lower ends of the front edge are closed by the closing body, the effect of preventing the insertion of paper waste and the adhesion of dust due to static electricity and preventing the deterioration of design can be exhibited.
