Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a passenger conveyor such as an escalator or an electric guideway, and particularly relates to safety equipment for a passenger conveyor suitable for preventing personal accidents around the passenger conveyor. .

[Background of the idea]

In general, passenger conveyors are widely used as essential service equipment in department stores and shopping stores.

Particularly recently, with the expansion of shopping centers into rural areas, safety has begun to become more important as shopping centers are used by large numbers of people and have become highly public facilities.

Injury accidents on passenger conveyors frequently occur around moving steps and handrails, followed by falls caused by approaching or entering dangerous areas such as deck covers.

Conventional safety equipment for preventing such intrusion into the deck cover is shown in FIGS. 1 to 3.

That is, the conventional passenger conveyor is constructed with the main components being a step 1 which is arranged in an endless manner and rotates, and a parapet 3 that prevents rotating bodies such as the handrail 2 and stationary bodies.
This is installed on the lower floor 4 and upper floor 5.

Around the passenger conveyor on the upper floor 5, there are an atrium section 6 through which it passes, a handrail 7, a protection plate 7a, etc. In addition, there are some component parts 3, such as an inner deck cover 8, an outer deck cover 9, and a handrail frame 10. Generally, a transparent glass panel 11, a skirt guard 12, a support column 13, etc. are arranged.

The basic configuration of the balustrade is to support the handrail frame 10 by appropriately arranging columns 13 on the balustrade 3, and to guide the movement of the handrail 2 in an aggressive manner.

Here, one of the above-mentioned personal accidents occurred when a mischievous child or an unscrupulous person entered the outer deck cover 9 from the front and side of the reversed part of the handrail 2, and the stairwell continued to open.
This is an example of a fall from the ground to the lower floor 4.

As a preventive measure against this, the protective plate 15 is fixed to the pillar 13 of the handrail 3 near the upper floor 5 using screws 14, etc.
The most common form is to attach a protective plate 7a to the area to prevent entry.

However, not all passenger conveyors can attach the protection plate 15 using the pillars 13, and in order to improve the transparency of the entire parapet for design purposes, the pillars 13 may be completely abolished, or
In some cases, the handrail frame 10 is made as small as possible and housed inside the handrail 2 to enlarge the transparent area of the glass panel 11.

For this reason, in recent balustrade configurations, the protective plate 15 is
3 or the handrail frame 10, and some attempts have been made to attach it to the glass panel by adhesive instead.

However, problems remain in terms of reliability as safety equipment whose mission is to prevent people from falling.

That is, applying an adhesive to glass is not suitable for attaching a member that is subjected to external force because the adhesive tends to peel off due to deterioration over time.

[Purpose of invention]

This invention was made to improve the above points,
The purpose is to provide safety equipment for a passenger conveyor that can prevent human bodies from entering the outer deck cover from the front and sides, and can maintain the strength of the protective plate without supporting it on the railing.

[Summary of the idea]

In order to achieve the above object, the present invention mechanically attaches a protective plate to the outer deck cover.

However, if a simple plate is attached, the attached part will easily be destroyed by external force, so the front part and the side surfaces connected to it are designed by bending the protective plate into a flat shape to prevent intrusion from the front and sides of the human body. and the protection plate is placed on the outer deck cover so that the front part extends to the front side and the side part extends to the back side of the front part to hold the front part and the lower part of the side part. It was attached using a tool.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

Incidentally, in FIGS. 4 and 5, the same reference numerals as in FIGS. 1 to 3 indicate the same members, so the explanation will be omitted.

The handrail 16 according to this embodiment does not have the pillars 13 or the large handrail frame 10 as in the conventional case, but has a strong glass panel 17 (about twice the thickness of the conventional one) and the handrail 2 runs on it. This differs from the conventional one in that it includes a small guide rail 18 (housed inside the handrail 2) for guiding the handrail.

The safety equipment 19 according to the present invention includes a protection plate 20 formed in a planar shape with a front part 20a having a width sufficient to prevent the intrusion of the human body and a side part 20b connected to the front part 20a.
It is comprised of a holder 21 that joins the lower portions of the front face 20a and side face 20b of the protection plate 20 onto the outer deck cover 9.

Further, the protection plate 20 has the front portion 20a located at the front so as to be orthogonal to the moving direction of the handrail 2,
It is arranged on the outer deck cover 9 so that the side surface portion 20b is located on the opposite side of the glass panel on the back side of the front surface portion 20a and extends along the handrail movement direction.

The holders 21 are L-shaped, and one side of the two holders 21 is opposed to each other so as to sandwich the lower portions of the front part 20a and the side part 20b of the protection plate 20 placed on the outer deck cover 9. It is integrally fastened with a screw 22 and a nut 23.

On the other hand, the other sides of the holder 20 are fixed onto the outer deck cover 9 with screws 24, respectively.

By configuring such an installation, the protection plate 2
The lower edge of the side surface portion 20b of 0 comes into contact with the outer deck cover 9, and the front surface portion 20a is moved as shown by the imaginary line S due to the external force F (force pushed by a person trying to enter the outer deck cover 9). Since the curved portion is supported and resisted by the outer end P of the contact portion, the mounting is mechanically stable and the occurrence of the above-mentioned curve can be eliminated.

Further, this side surface portion 20b has the function of blocking people who try to enter from the side of the passenger conveyor as shown by arrow A (FIG. 4).

As described above, by providing the side surface portion 20b on the protection plate 20, the front surface portion 20a is not only reinforced, but also the attachment serves to improve the strength, increasing the overall rigidity, while at the same time having the advantage of preventing intrusion from the side surface. There is.

Therefore, suitable safety equipment can be installed in a parapet type that does not have columns or handrail frames.

[Effect of idea]

As explained above, according to the present invention, the protective plate can be installed without using a handrail, the strength of the protective plate can be stably maintained, and the reliability is such that it can prevent human bodies from entering from the side of the outer deck cover. It has the advantage of providing high safety facilities.
