Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to escalator-type equipment, including not only escalators but also electric roads running on gentle slopes, and particularly relates to escalator-type equipment including escalators and electric roads running on gentle slopes. The present invention relates to safety equipment suitable for preventing personal accidents at intersections.

[Conventional technology]

It is well known that escalators are equipped with numerous safety devices in case of accidents involving one person or equipment failure, and are evaluated as relatively safe equipment. but,
With the spread of escalators, accidents such as head collisions and head collisions of passengers occur when a moving escalator and a fixed building are close together at the junction with the building in which the escalator is installed. It is recognized that this is due to problems on the user side such as lack of caution and pranks, and the proximity of buildings to escalators due to a reduction in installation space. is widely used.

The safety equipment shown in this known example is located on the side of the building ceiling, etc., which is dangerous when a passenger M on the steps (not shown) leans out far from the handrail 2 and the parapet 3 as shown in Fig. 5. In order to warn that the lower part T is near, a substantially triangular warning body 4 is suspended from a chino 5, and when the passenger M comes into contact with this, the passenger M is alerted to draw back. Note that this triangular warning body 4 is unnecessary if the distance W between the outer edge of the handrail 2 and the side lower part T of the building ceiling, etc. is 5001 m or more, but if the distance is less than this, especially on an escalator as shown in Figure 5, it is unnecessary. When the lower part T of the building ceiling approaches the outside (distance wa)
The most dangerous included angle will be formed when the angle is approximately 200I or less.

[Problem to be solved by the invention]

The above-mentioned conventional technology has been evaluated as having prevented most of the accidents resulting in injury or death at triangular intersections. However, in the unlikely event that
If the passenger M raises his head Ma deeply to the direction F of the handrail 3 as shown in Fig. 5, and unconsciously pushes the triangular warning body 4 outward, the handrail 2 and the building ceiling, etc. Lower side T
The head is caught between the two, as shown by the hatched circle 2, and this results in pressure on the head. This phenomenon is caused by the triangular warning body 4.
This is due to the fact that it is suspended from the chino 5 and can be swung from side to side.

In addition to this conventional technology, warnings by flashing caution lights,
Although warnings using audio devices are known, they are not considered to be a decisive factor in terms of safety, and have not yet been adopted.

An object of the present invention is to provide safety equipment for escalators that prevents serious accidents by providing safety equipment to prevent human bodies from entering the dangerous parts of triangular intersections, which are the most narrow angles.

[Means to solve the problem]

The above purpose is to install the bottom of the escalator adjacent to the outside of the handrail when viewed from the front direction of the escalator, or the side lower part of the building ceiling, etc., at the intersection of this side lower part and the moving handrail (as seen from the side of the escalator). At the triangular intersection formed by the intersection of the side surface of the ceiling, etc. and the top surface of the handrail, a substantially triangular side guard plate is attached to the building ceiling, etc., and extends in the longitudinal direction of the escalator. This is achieved by providing a human body intrusion prevention body consisting of a front guard plate installed at the front of this side guard plate and placed so as to close the widthwise gap between the notebook and the building ceiling, etc. be done. Furthermore, by providing a swingable triangular warning body on the building ceiling or the like in front of the human body intrusion prevention body, dangerous areas can be notified early on, and safety is further improved.

[Effect]

Passenger M on the escalator steps turns sideways and ascends with his head bowed to the bottom of the railing as shown in Figure 5, and unconsciously pushes the triangular warning body outward with his head Ma and passes. In this case, this head Ma will touch the front guard plate on the upper side of the outer deck cover to return to its original position. At this time, even if the body does not return, the side guard plate extending along the escalator's long direction prevents the head Ma from entering the included angle, and the human body consisting of these two guard plates prevents the human body from entering. The preventive body prevents personal accidents at triangular intersections where human bodies such as the head Ma are pressed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

The escalator body includes steps 1 that are connected in an endless manner and move, a handrail 2 that moves in synchronization with the steps, a handrail 3 that is provided to guide and support the movement of the handrail 2, a handrail panel 3a that constitutes this, and an outer deck. force/<-3b, etc., and at the bottom of another escalator that is close to this escalator, or at the corner Ta of the lower side T of the ceiling of the building, etc.,
A triangular warning plate 7 is suspended on the side of the lower entrance 6 by a swingable mounting means such as a chino 8, and a triangular warning plate is attached to the rear of this from the intersection (point K) of the lower side 'r and the handrail 2. A human body intrusion prevention body 9 extending toward the side 7 is attached by a mounting bracket 10. This human body intrusion prevention body 9 is
A side guard plate 9a and a front guard plate 9b that is provided in front of the side guard plate 9a and closes the gap between the escalator and the lower side T;
It is equipped with a front guard 9c whose front part is rounded to protect collision objects, and is attached to the lower side T. Here, both the triangular warning body 7 and the human body intrusion prevention body 9 are approximately triangular with an upper surface that follows the lower surface of the building ceiling, etc., and a lower surface that follows the slope of the handrail 2 (the triangular warning body 7 has a rounded front surface). It is a trapezoid with a certain protection part 7a).

The length L & of each of these is approximately 200 to 500 m (height h
Ideally, a should be greater than or equal to the diameter of the head), and the interval L & is 10
It is installed with dimensions of about 0-200 nu and length Lc of about 1000 IIn. Furthermore, human body intrusion prevention body 9
is such a size that it closes the width of the outer deck cover 3b with a gap hb of several holes from the lower surface of the handrail 2. For example, if the head Ma in the state described in FIG. When the human body passes through the angle, push it up as shown by arrow A (Figure 2), or physically prevent the human body from entering the angle as shown by arrow B.

The optimal material for the human body intrusion prevention body 9 is a durable transparent acrylic plate that does not obstruct the passenger's view.

In addition, the attachment parts of this human body intrusion prevention body 9 include a head Ma.
As a shock mitigation measure in the event of a collision, the escalator can swing in the direction of travel of the escalator (symbol Q in Figure 4) as shown in Figure 4.
In the width direction (symbol C in FIG. 4), a hinge type or spring type is used, which has little movement.

In this way, by providing a safety device in which the side guard plate and the front guard plate are combined into an integrated product at the triangular intersection, it is possible to prevent personal accidents at dangerous angles.

Note that the means for attaching the human body intrusion prevention body 9 differs depending on the form of the parapet, building ceiling, etc., and the optimum structure is adopted for each form.

〔Effect of the invention〕

According to the present invention, it is possible to provide safety equipment for escalators that can prevent personal accidents at triangular intersections formed between escalators and surrounding fixed objects.
