DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined type passenger transporter such as an escalator, and more particularly, to a moving handrail moving in an ascending direction and a fixed object approaching the moving handrail to form a wedge-shaped space. It relates to the configuration of safety equipment to be equipped.

[0002]

2. Description of the Related Art Generally, between a moving handrail which is provided at an upper end portion on both sides of a passenger carrier (such as an escalator) and moves in an ascending direction, and a fixed object (an obstacle) which is located close to the moving handrail. It is known that a safety device commonly referred to as a synthetic resin triangular guard plate is provided, and measures are taken to prevent a passenger's head having leaned out of the moving handrail from being caught in the head. As an example, see JP-A-10-13
No. 9346 first safety equipment (oscillating type)
And the second safety equipment (fixed type) combined type additional safety guidance means.

[0003]

As a problem in the above-mentioned conventional combined safety equipment, when the first safety equipment and the second safety equipment are fixed to a fixed object such as a ceiling, each of them is fixed. Since the fixing method is performed separately, a fixing member such as a fixing screw and a holding member are required, so that mounting of the fixing member and the holding member is complicated, and an interval between the first safety equipment and the second safety equipment is arranged. Fixing (equipment) work such as time-consuming positioning is inefficient, and mounting is performed in an upward position. Further, there is a problem that these safety equipments are dropped by an external force due to a head injury or mischief.

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. The first safety facility has a buffering and drop prevention function with respect to the first safety facility, by supporting the composite safety facility provided between the first safety facility and the first safety facility by supporting the combined safety facility with a single support structure. The purpose is to obtain an equipment configuration that is also excellent in increasing safety by making it work.

[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,
A rod-shaped first safety device installed in a suspended state at a front portion of a wedge-shaped space formed between a fixed object having a different inclination angle from the moving handrail, and a rear portion of the first safety device. A substantially triangular second
Wherein the second safety equipment is fixedly supported on the fixed object, and the first safety equipment is provided with the first safety equipment.
When an external force is applied to the first safety facility by a spring body at a certain distance from the second safety facility with respect to the second safety facility, the gap changes. In such a manner as to be fixed.

[0006] With this configuration, the safety equipment for a passenger transporter of the present invention has the first and second safety equipment constituting the same as an integrated combination via a spring body. Since the fixing work of each safety equipment is performed on a flat ground (such as the floor on which the passenger transport is installed) and then attached to a fixed object, it is possible to reduce the height and dangerous work in an upward posture. In addition, the first safety equipment is fixed to the front edge of the second safety equipment via a spring body, while the second safety equipment is directly fixed to the fixed object, so that the head and the like are fixed. Even in the case of a collision, it is possible to obtain a configuration of safety equipment having high overall safety, such as softening the impact and preventing falling.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a safety device for a passenger transporting vehicle to which the present invention is applied. FIG. 1 shows an escalator 1 moving in an ascending direction in an inclined passenger transport, and a fixed object 2 above the escalator 1.
FIG. 2 is a front view of a cross section taken along line AA of FIG. 1 with emphasis on a first safety facility 3 and a second safety facility 4 at a portion intersecting with (for example, a ceiling of an upper floor). , FIG. 3 is B-
It is sectional drawing which follows the B line. As shown in FIG. 1, the escalator 1 is installed at an inclination between upper and lower floors having a height difference, and a step 1A for transporting passengers, and a pair of left and right moving handrails provided at upper ends on both sides of the step 1A. 1B and a balustrade 1C which is a structure for guiding and supporting the rail 1B. Also,
At the rear of the wedge-shaped space Q between the moving handrail 1B and the fixed object 2 that intersects with the moving handrail 1B and the balustrade 1C at a different inclination angle, a mounting bracket 4a is attached to the fixed object 2.
Then, the second safety equipment 4 whose upper and lower edges are fixed to the balustrade 1C with the mounting bracket 4b is provided to close the narrow space where the head of the triangular intersection is most likely to be caught. On the other hand, the first safety equipment 3 uses a cylindrical rod-shaped body, and is spaced apart from the second safety equipment 4 at a fixed distance m by a spring body 5 fixed to the front edge 4A of the second safety equipment 4. When an external force acts on the first safety equipment 3 by the spring body 5, the distance m changes (shrinks) or changes as indicated by the imaginary line n in FIG.

The first safety equipment 3 has a structure in which the spring body 5 is free to displace and cushions the collision shock of the head contacting the spring body 5, while preventing the fall due to the impact force by the fixing force of the spring body 5. Has become.

As described above, each of the safety equipments 3 and 4 of the present invention is provided.
Are mounted as an integrated combination and then fixed to the fixed object 2. In these mounting operations, the arrangement interval between the first safety equipment 3 and the second safety equipment 4 is set. In addition to being unnecessary, it can be mounted on a level surface that is safe and efficient, and is particularly effective in reducing the work area at a high place.

Each of the safety equipments 3 and 4 used in the description of the above-described embodiment can be applied to a moving sidewalk which is a passenger transporter, similarly to the escalator 1, and its material and color tone can be changed as required. Can be selected arbitrarily.

[0011]

As described above, according to the present invention, the passenger moving in the ascending direction by the passenger transporter moves between the moving handrail and a fixed object such as a ceiling which approaches the moving handrail and forms a wedge-shaped space. By increasing the efficiency of work of fixing to fixed objects by making the combined safety equipment provided as an integrated product, the first safety equipment is provided with a buffer and a fall prevention function to increase safety. It can also provide an excellent equipment configuration.
