Abstract

PURPOSE: To provide sufficient mounting strength by providing an almost triangular protector at the triangular intersecting section of both passenger conveyors, and coupling and fixing the upper side of the protector to a recessed groove formed on the bottom exterior panel of the second conveyor, regarding a system made of the first and second passenger conveyors intersecting and adjacent to each other. CONSTITUTION: The safety facility 5 to protect a passenger's head ascending on board a passenger conveyor 1 overhangs above a corner section 6C formed out of the side exterior panel 6A and bottom exterior panel 6B of another passenger conveyor 6. The facility 5 is formed out of a protector 7 laid at the narrow angle side of the intersection of both conveyors 1 and 6, and another protector 8 at the wide angle side. Also, the protector 7 has the upper side thereof coupled to and supported on an inverted U-shaped groove 6D formed out of the lower U-shaped end 6a of the side exterior panel 6A of the conveyor 6 and the inverted Z-shaped section 6b of the bottom exterior panel 6B thereof. In addition, the upper side is fixed with a caulking agent 6E, thereby laying the protector 7 in suspended state.

Description

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, the above-mentioned structure has a problem that it is difficult to maintain strength when it 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 case where the first protective body is provided on the narrow angle side, and the second protective body is provided on the front and bottom corner sides of the first protective body,
The first protector is configured such that the upper side of the first protector is fitted into the recessed groove formed on the side of the first passenger conveyor at the bottom of the bottom exterior plate, and is fixed in the recessed groove.

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

Further, the first protective body is fitted and fixed in the concave groove portion as described above, and is fixed to the bottom exterior plate by the fixing body.

The above construction is applied as it is even when there is no second passenger conveyor and there is a bottom exterior plate such as a ceiling of a building in place of the second 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 fitted and fixed in the groove formed in the bottom armor plate on the side closer to the side armor plate of the second passenger conveyor. 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 both side surfaces of the first protective plate are fixed to the bottom exterior plate by the fixed body, the external force along the traveling direction of the first passenger conveyor (passenger collision) and the lateral external force described above. 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 (passenger). Even if the second protective body collides against the first protective body and is damaged, the second protective body has an effect of impacting the colliding object by rocking.

[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
The attention zones 2B and 2C are provided on the front side and both sides of the tread 2A to contribute to the improvement of safety. On the other hand, on the outer side of the balustrade 3 on the passenger conveyor, 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. Corner 6C
It is provided in the part. The safety equipment 5 has a protective body 7 on the narrow angle side where the starting point A where the two passenger conveyors 1 and 6 intersect is located.
On the wide-angle side in front of this, the protector 8 is suspended by the chain 8A on the bottom exterior plate 6B so as to be swingable so as to buffer the impact force of the head or the like that collides with this.

Protective body 7 and protective body 8 constituting the safety equipment 5
Among them, the protector is attached to the bottom exterior plate 6B 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
Only in the U-groove portion 6D in the reverse direction at the depth h formed by the lower end U-shaped portion 6a of the side exterior plate 6A of the passenger conveyor 6 and the inverted Z portion 6b of the bottom exterior plate 6B. The upper side of 7 is fitted and supported, is fixed by caulking agent 6E, and is arranged so as to hang from the bottom exterior plate 6B by H in the height direction. In addition, the total length of the protective body 7 is the U groove portion 6
In addition to being fixed by being fitted into D, it is further fixed by being fixed to the bottom exterior plate 6B by the L-shaped fixing body 9 and the screw 10 to further increase the strength. Here, the side exterior plate 6A and the bottom exterior plate 6
Inside B is a body frame 6F and a support tool 6G connected thereto.

Further, between the protective body 7 and the protective body 8,
A space 1a (FIG. 2) of about 100 mm is provided, and when the head or the like collides in front of the second protector 8, the chain 8A sways to buffer the impact force, while the space 1a protects the protector 8 from the impact. Of the protective body 7 is prevented from colliding with the front portion of the fixed protective body 7.

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 target is the building ceiling, it can be applied as it is by providing the U groove portion, and the same effect can be obtained.

[0018]

According to the present invention, it is possible to improve the attachment 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 to achieve the function as safety equipment.
