JPH1036053A - Safety facility of passenger conveyor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a safety facility that prevents the intrusion of human bodies onto a railing deck, is high in mounting strength, and is unlikely to deform even when pressed strongly so as to prevent human bodies from dropping. SOLUTION: A passenger conveyor includes moving steps connected together endlessly, handrails, and a railing 5 serving as the side wall between the steps and the handrail, and an intrusion preventer 7 that blocks the breadth of a railing deck 5C is provided in a space part formed by a railing frame 5A, a railing panel 5B, and the railing deck 5C which constitute the railing 5, on the outside of the intrusion of the passenger conveyor. In this case, the preventer 7 is a combined structure of a first preventer 7A which extends along the outside surface of the railing panel 5B and projects toward the end of the railing 5 and a second intrusion preventer 7B integrated with the preventer 7A while in a form perpendicular to the preventer 7A to block the breadth of the railing deck 5C, and the combined structure is secured to the upper surface of the railing deck 5C by fasteners.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and a moving walkway, and more particularly to a safety device for preventing a human body from entering a balustrade deck from the outside of an entrance.

[0002]

2. Description of the Related Art As a conventional technique for preventing a human body from entering a dangerous part around a passenger conveyer's entrance / exit, a type having a balustrade pillar provided outside a balustrade body and having an entry-preventing body attached thereto (for example, Japanese Unexamined Patent Publication (Kokai) No. H11-163873). JP-A-50-150180) and those equipped with an entry blocker having a guidance display function (for example, JP-A-59-158783).

[0003]

The former of the above conventional example is as follows.
The latter focuses on the guidance display function to prevent mischief and improve operability of the operation switch equipped on the balustrade,
It was not intended to improve the installation strength or safety of safety equipment. For this reason, the conventional equipment has problems in terms of mounting strength and safety.In particular, an infant or the like approaching the outside of the upper floor entry / exit hangs on the handrail and collides with the entry barrier from above the balustrade deck. This resulted in a serious accident that caused the obstacle to break and fall downstairs.

[0004] It is an object of the present invention to provide a safety device that prevents a human body from entering a balustrade deck, has a high attachment strength, is hardly deformed even when pressed strongly, and prevents a human body from falling. is there.

[0005]

An object of the present invention is to provide a step and a handrail which are connected endlessly and move, and the balustrade outside the entrance of a passenger conveyor having a balustrade as a side wall between the step and the handrail. In the space formed by the balustrade frame, balustrade panel and balustrade deck that make up the body,
A barrier for closing the horizontal width of the balustrade deck, wherein the first barrier is configured to protrude toward the front end of the balustrade along the outer surface of the balustrade panel; A composite structure of a second approach block that is integrated in a shape orthogonal to the approach barrier of the second and blocks the lateral width of the balustrade deck, and this composite structure is fixed to the upper surface of the balustrade deck with a fixture. Is solved by

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the interlocking relationship between a step 3, a handrail 4, a balustrade 5 and a fall prevention fence 6 arranged outside the structure near the upper entrance 2 which is one entrance of the passenger conveyor 1. It is a thing. Here, as shown in FIG. 2, the structure of the passenger conveyor 1 is a space Q formed between a balustrade frame 5A, a balustrade panel 5B, a balustrade deck 5C and a fall prevention fence 6, which constitute the balustrade 5.
The safety equipment having the entry preventing body 7 as a main product is provided. As shown in FIG. 3, the entry barrier 7 extends along the outer surface of the balustrade panel 5 </ b> B and projects toward the tip end of the balustrade 5 by a length La. A U-shaped second portion having a front portion 7a having a width W for closing the width of the balustrade deck 5C and both side portions 7b having a bent length Lb is integrated (by adhesion or the like) in a shape orthogonal to the one entry blocking body 7A. Is a composite structure of the entrance blocking member 7B, which is provided on the upper surface of the balustrade deck 5C and the reinforcing member 5CC with the fixing tool 8 and the screws 9,1.
It is fixed at 0 and stands upright at the height H to the handrail 4 side. In this case, the entry blocking body 7 is made of a transparent material such as an acrylic resin material, a polycarbonate material, or a vinyl chloride material, so as to achieve design harmony with the transparent balustrade panel 5B.
Here, in particular, the presence of the first approach-inhibiting body 7A is determined by riding on the balustrade deck 5C from the leading end side of the balustrade body 5, and
There is an effect of preventing an infant or the like hanging down from entering the balustrade deck 5C by the protruding length La. In addition, the second approach blocking body 7B has the effect of closing the width of the balustrade deck 5C with its width W, and reliably preventing a child or the like from falling downstairs. Further, the first entry block 7A and the second entry block 7B act synergistically to significantly improve the strength and prevent deformation and breakage.

[0007]

According to the present invention, while the human body is prevented from entering the balustrade deck, the mounting strength is high, the human body is hardly deformed even if pressed strongly, and the human body can be prevented from falling.
