Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to safety equipment for passenger conveyors such as escalators and electric roads, and more particularly to a safety enhancement structure between adjacent passenger conveyors.

[0002]

2. Description of the Related Art Conventionally, as means for preventing a head collision accident of a passenger which occurs between passenger conveyors or between a passenger conveyor and a building ceiling adjacent to the passenger conveyor, it has been disclosed in Japanese Patent Application Laid-Open No. HEI-6
The 2-52897 publication is known.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned known example, in order to prevent the head of passengers from entering, a first protector provided at the starting point where the building ceiling and the passenger conveyor intersect is added to this. When an impact force is applied, it is moved a little to reduce the impact force. However, this structure has a problem that it is difficult to maintain strength when the structure is attached to the ceiling of the building or the bottom of the adjacent passenger conveyor. Reasons for this are that most of the materials for the building ceiling and the like are gypsum boards and the like, and many of the bottom exterior plates are thin steel plates, and sufficient strength cannot be obtained by fixing screws or the like.

An object of the present invention is to improve the mounting strength of the first protective body mounted on the side of the starting point of the intersection between adjacent passenger conveyors, and to improve the function as safety equipment.

[0005]

In order to achieve the above object, the present invention is formed by a bottom exterior plate of a second passenger conveyor which intersects with and is adjacent to a first passenger conveyor having a balustrade or the like. In the one in which the first protective body is provided on the narrow-angle side, and the second protective body is provided on the front side of the first protective body and on the wide-angle side,
The first protector is configured to hold the attachment strength by closely contacting the upper side portion of the lower side exterior plate with the lower end concave side portion formed on the first passenger conveyor side. is there.

Further, a second protective body is fixed to the front and wide-angle sides of the first protective body at a constant distance from the first protective body and is suspended from the bottom exterior plate.

Further, the first protector is fixed to the lower concave side portion as described above and is fixed to the side exterior plate with a screw or the like.

[0008] Incidentally, even if there is no second passenger conveyor, and there is a side exterior plate such as the ceiling of the building instead of this, this configuration is applied as it is, but the following will be referred to as the first passenger conveyor. The installation form in which the second passenger conveyors cross and adjoin will be described as a typical example.

[0009]

The upper side of the first protector is tightly fixed to the concave side of the lower side of the side exterior plate of the second passenger conveyor, which has a slightly stepped lower end, so that its entire length is flat. It is supported, has sufficient mounting strength, and is less likely to fall or be damaged by being hit or pushed by passengers of the second passenger conveyor.

Further, since the upper side portion of the first protective plate is fixed to the side exterior plate by a screw or the like, an external force (passenger collision) or a lateral external force along the traveling direction of the first passenger conveyor is applied. Also, the strength is further improved.

Further, the second protector is hung at the front and wide-angle sides of the first protector at a constant interval from the first protector, so that the suspending tool swings (passengers). Even if the second protective body collides with the first protective body and is damaged, the effect of buffering the impact of the colliding object by swinging is eliminated.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, the passenger conveyor 1 is provided with handrails 4 that are connected endlessly and move in parallel with step 2 along the upper edges of the balustrade 3 and the balustrade 3 that are vertically arranged on both sides of the step 2 and step 2. There is. In addition, step 2 is
Caution zones 2B and 2C are provided in front of and on both sides of the tread 2A to contribute to improvement of safety. On the other hand, outside the balustrade 3 of the passenger conveyor 1, a safety equipment 5 for protecting the heads of passengers riding on the passenger conveyor 1 is formed by a side exterior plate 6A and a bottom exterior plate 6B of the passenger conveyor 6. It is provided at the corner 6C. The safety equipment 5 includes a protector 7 on the narrow angle side where the starting point A where the two passenger conveyors 1 and 6 intersect is located,
On the front wide angle side, a protector 8 is suspended by a chain 8A on a bottom exterior plate 6B so as to be swingable so as to buffer the impact force of a head or the like that collides with this.

Protective body 7 and protective body 8 constituting the safety equipment 5
Of these, the protector is attached to the side exterior plate 6A as shown in FIG.

In FIG. 1, which is a sectional view taken along the line I--I of FIG. 2, from the outer edge of the handrail 4 of the passenger conveyor 1
Side recessed portion 6b of the lower end concave side portion 6a (height h of the recessed portion) of the side exterior plate 6A of the passenger conveyor 6 adjacent to and separated from the side exterior plate 6A by ha corresponding to the plate thickness of the protector 7 )
The upper side of the protective body 7 is supported on one side in full contact with
Further, it is arranged so as to hang from the bottom exterior plate 6B by H in the height direction. The total length of the protector 7 is
In addition to being fixed to the flat surface of the lower end concave side portion 6a, it is set within the range of the retreat amount ha and is fixed by the screw 9 to further increase the strength. Here, inside the side exterior plate 6A and the bottom exterior plate 6B are a main body frame 6D and a support tool 6E connected thereto.

Further, between the protective body 7 and the protective body 8,
A gap la (FIG. 2) of about 100 mm is provided. When a head or the like collides in front of the protector 8, the chain 8A sways to buffer the impact force, while the gap la fixes the protector g. It is prevented from colliding with the front part of the protective body 7 that is being installed.

By doing so, there is an effect that the mounting strength of the protector is particularly improved and the function of the safety equipment is enhanced.

The above is not limited to the safety equipment between the adjacent passenger conveyors, and even if the building ceiling is the object, it can be applied as it is by providing the concave portion on the lower end, and the same effect can be obtained.

[0018]

According to the present invention, it is possible to improve the mounting strength of the protector provided on the side of the intersection of the building ceiling and the bottom exterior plate adjacent to the passenger conveyor, and improve the function as safety equipment.
