Abstract

PURPOSE: To prevent escalation to severe accident by arranging a triangular part approach preventing element at a cross point between a side lower surface and a moving handrail of a building's ceiling, a human body approach preventing element outside of a railing under the front part of the preventing element, and an oscillatable triangular part alarming element on its putting on/off opening side. CONSTITUTION: At a corner Ta of a side lower surface T of the bottom of another escalator approaching to an escalator or a building's ceiling, a triangular part alarming element 7 is oscillatably hung on its lower part putting on/off opening 6 side with a chain 8, and a triangular part approach preventing element 9 extending from a cross point K between the side lower surface T and a moving handrail 2 to the alarming element 7 is attached to its rear part. A human body approach preventing element 11 is fixed on an outside deck cover 3b in the front of at least the preventing element 9 between the cross point K and the front part of the alarming element 7 so as to block between a handrail panel 3a and the outer edge of the escalator. When a head part pushes aside the alarming element 7 and passes there, the preventing element functions for pushing up it and for approach prevention. When the head part passes through the alarming element 7 and the preventing element 11 to a narrow corner, the preventing element 9 is constituted to physically prevent approach of the head.

Description

[Detailed Description of the Invention] [Industrial Application Field] 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, and particularly relates to escalator-type equipment including escalators and electric roads running on gentle slopes. This invention relates to safety equipment suitable for increasing the safety of triangular intersections.

[Conventional technology]

It is well known that escalators are equipped with a number of safety devices to prevent accidents resulting in injury or equipment failure, and are evaluated as relatively safe equipment. However, when a moving escalator and a fixed building come close to each other at the junction with the building where the escalator is installed, serious accidents such as head collisions of passengers and accompanying falls or falls have been observed. , a solution is desired.

Accidents such as head collisions are caused by problems on the part of users such as lack of caution when using escalators, pranks, and obstructions approaching escalators due to the reduction in installation space as escalators become more widespread. Recognized as such, for example, the safety equipment disclosed in Japanese Utility Model Application Publication No. 51-66992 is widely used.

The safety equipment shown in this known example is designed to protect the ceiling of the building, etc., which can be dangerous if a passenger M on the steps 1 (not shown) leans too far over the handrail 2 and the parapet 3 as shown in Fig. 5. Lower side T
Approximately triangular triangular warning body 4 to warn that
is suspended from Cheno 5, and if passenger M comes into contact with it, he or she is warned to step 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 500 mm or more, but if the distance is less than this, especially escalators as shown in Fig. 5. −
When the lower T of the building ceiling approaches the outside of the building (
The most dangerous included angle will be formed where the distance wa is approximately 200 mm or less.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has been evaluated as having been able to prevent most of the accidents resulting in injury or death at triangular intersections. However, in the unlikely event that passenger M lowers his head deeply below the handrail 3 as shown in Figure 5 and unconsciously pushes the triangular warning body 4 outward, the handrail 2 and the ceiling of the building It is narrowed between the lower side T of the body and the lower side T, as shown by the hatched circle 2, resulting in pressure on the head. This phenomenon can be said to be due to the fact that the triangular warning body 4 is suspended from the chino 5 and can swing from side to side.

In addition to the conventional technology mentioned above, there are also warnings by flashing caution lights,
Although warnings using audio devices are known, they cannot be said 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 for solving problems]

The above purpose is to prevent the escalator from intersecting with the moving handrail (directly sideways from the escalator) in an installation configuration in which the bottom of the escalator adjacent to the outside of the escalator or the side lower part of the building ceiling is close to the outside of the handrail when viewed from the front direction of the escalator. At the point where the lower side of the ceiling, etc. intersects with the upper surface of the handrail), a nearly triangular intrusion prevention body is placed at this intersection (the point where the lower side of the ceiling, etc. intersects with the upper surface of the handrail), and the front part of this triangular intrusion prevention body (the point where A human body intrusion prevention body is installed on the outside of the lower handrail (exit side), while a triangular warning body that is swingably attached to the building ceiling, etc. is placed on the lower entrance/exit side in front of this triangular part intrusion prevention body. This is achieved by

[Effect]

Passenger M on the escalator steps turns sideways and ascends with his head lowered to the bottom of the railing as shown in Figure 5, and unconsciously pushes the triangular warning body outward with his head Ma. If it passes through, the head Ma will come into contact with the human body entry prevention body on the deck cover and return to its original position. However, even here, if the head Ma is placed near the lower surface of the ceiling or the like without returning, the final equipment, the triangular part entry prevention device, prevents the head Ma from further entering the included angle. It has become. This prevents personal accidents at triangular intersections where the head Ma and the like are pressed.

〔Example〕

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

The escalator body consists of 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 handrail 2, a handrail panel 3a that constitutes this, and an exterior. Equipped with a deck cover 3b, etc., another escalator near this varnished
A triangular warning body 7 is suspended from the lower entrance 6 side by swingable mounting means such as a chino 8 at the corner Ta of the side lower part T of the bottom of the building or the ceiling of the building, etc. A triangular part intrusion prevention body 9 extending from the intersection (point k) of T and the handrail 2 toward the triangular part warning body 7 side is attached by a mounting bracket 10. At this intersection, the triangular warning body 7 is placed.
On the outer deck cover 3b at least in front of the triangular part intrusion prevention body 9, there is a human body intrusion prevention body 1 so as to close the space between the handrail panel 3a and the outer edge of the escalator.
1 is fixed by metal fittings 11a, screws llb, etc.

Here, both the triangular part warning body 7 and the triangular part intrusion prevention body 9 are approximately triangular with an upper surface along the lower surface of the building ceiling, etc., and a lower surface along the slope of the handrail 2 (the triangular part warning body 7 has a rounded front part). The length La of each of these is about 200 to 500 mm (height ha).
Ideally, the distance should be greater than or equal to the diameter of the head), and the interval Lb should be 100
The length Lc is about 1,000 millimeters and the length Lc is about 1,000 millimeters.

Furthermore, the human body intrusion prevention body 11 is attached to the outer deck cover 3b with a distance hb of several centimeters from the lower surface of the handrail 2.
For example, when the head Ma in the state described in Fig. 5 pushes aside the triangular warning body 7 and passes it, it pushes it up as shown by arrow A (Fig. 2). , which acts to prevent entry. On the other hand, if this head Ma passes through both the triangular part warning plate 7 and the human body intrusion prevention body 11 and does not reach the included angle, the triangular part intrusion prevention body 9 moves the arrow B
As shown in FIG. 2, it is configured to physically prevent the head Ma from entering.

In addition, the attachment part of this triangular part intrusion prevention body 9 has a head Ma.
As shown in Figure 4, the escalator is a hinged type that can swing in the direction of movement of the escalator (code Q in Figure 4) and has little movement in the width direction (C in Figure 4) as a shock mitigation measure when the escalator collides with the escalator. Alternatively, a spring mounting bracket 10 is used.

As described above, by providing the safety membrane comprising the triangular part warning body 7, the triangular part intrusion prevention body 9, and the human body intrusion prevention body 11, accidents resulting in injury or death at narrow angles can be prevented. Note that the means for attaching the warning body and both prevention bodies differs depending on the form of the parapet, building ceiling, etc., and the optimum structure is adopted for each.

〔Effect of the invention〕

According to the present invention, there is an advantage that it is possible to provide safety equipment for an escalator that can prevent personal accidents at the triangular intersection formed between the escalator and surrounding fixed objects.
