Description

The present invention relates to a fall accident prevention type escalator in which a moving step and a handrail belt form a ramp or a horizontal road to transport passengers.

Conventionally, as a device for preventing a fall accident on an escalator, a configuration of a display unit in which a display sheet is attached to the surface of a handrail belt to display a direction display mark, a caution display, and an advertisement display has already been proposed, for example, as in Patent Document 1. It has been granted rights.

The display sheet for the handrail belt described in Patent Document 1 has become more widespread in the world and is exerting a remarkable effect in preventing personal injury accidents, especially fall accidents.

Japanese Unexamined Patent Publication No. 2006-347764 (Registration No. 4998863)

In the above-mentioned Patent Document 1, the display sheet makes it easier to understand the moving direction and the sense of speed of the escalator by the direction display mark or the like existing at a position close to the passenger's eyes, and the failure of boarding in the reverse direction or the failure of getting on / off timing is reduced. It is highly effective, and as a result, it has been evaluated as having a high actual effect of preventing falls. In addition, the safety and advertising effectiveness of the caution wording provided within the interval of the direction display mark and the display part of the advertisement are also evaluated.

On the other hand, in the recent use of escalators, in addition to the above-mentioned safety and advertising effect, it has been urgently desired to extend the life and increase the reliability of this part, such as preventing the joint part of the display sheet from peeling off and getting dirty. ..

An object of the present invention is the length of the display sheet provided on the surface of the handrail belt, such as the safety and advertising effect of the display part such as the direction display mark and the caution wording, and particularly the prevention of peeling and dirt at the seam part of the display sheet. The purpose is to provide a fall accident prevention type escalator with a configuration that can contribute to a longer life and higher reliability.

In order to achieve the above object, claim 1 of the present invention includes a step that moves from one entrance to the other entrance and transports passengers, and an endless handrail belt that moves synchronously with this step. In the escalator, the surface of the handrail belt is substantially covered with the cross-sectional shape and is divided into a plurality of pieces in the longitudinal direction thereof, while the joint portion has a stacking allowance of a certain length and the moving direction is defined. A display sheet having a plurality of direction display marks that serve as a mark for displaying and transferring to the escalator is attached and provided, and a length in a range longer than the overlapping margin portion of the seam of the display sheet is covered. Further, a display sheet composed of a seam material with an adhesive provided so as to cover the cross-sectional shape of the handrail belt is provided, and the handrail belt is moved with respect to the seam portion and the seam material of the display sheet. By setting the range in which the pulling force acts in the direction to more than half of the total length of the traveling path, dents that cause peeling or dirt appear on the surface of the seam material (the dent causes peeling or dirt). I tried not to.

Further, claim 2 of the present invention attaches the display sheet at the seam portion so that the lower end portion thereof is attached to the handrail belt and the upper end side portion covers the lower side end portion. In this state, the entire seam portion is adhered with a seam material with an adhesive, and the handrail belt is applied to a configuration in which the step moves in the ascending direction.

According to the above configuration, the direction display mark of the display sheet provided on the surface of the handrail belt visually indicates the moving direction and speed of the escalator, thereby facilitating the timing of boarding the escalator and preventing reverse boarding. On the other hand, the present invention provides a fall-prevention type escalator that can prevent peeling and dirt of the seam material provided at the seam portion of the display sheet, prolong the life of the portion, and improve the reliability.

The conceptual vertical sectional view which establishes the seam part of the display sheet of this invention.

Hereinafter, an embodiment of the fall accident prevention type escalator of the present invention will be described with reference to FIGS. 1 to 7.

The fall accident prevention type escalator 1 of the present invention has a main frame 3 mounted on the building 2 having an entrance / exit 2A connected to the upper floor of the building 2 and an entrance / exit 2B connected to the lower floor thereof, and an endless shape. A large number of steps 4 that are connected and move in reverse from the outward path to the return path, and move in reverse from the outward path to the return path in synchronization with this step 4, and the cross-sectional shape is the flat portion 5A and half of both edges connected to it. A handrail belt 5 having a width W1 forming a horseshoe shape with the circular portion 5B and adhesively fixed from the flat portion 5A (width W2) to the semicircular portion 5B along the longitudinal direction of the handrail belt 5 (detailed illustration is omitted). (It is a multi-layer material composed of a sheet portion layer on which an adhesive layer is provided on the inner surface side and a direction display mark 6A or the like, which will be described later, is printed on the outer surface, or a laminated layer on the surface). A scale display sheet 6 is attached.

Further, the handrail belt 5 is frictionally driven by the power transmitted to the drive roller 9 and the like via the chain 8 of the drive gear 7, and is guided by the guide roller 10 on the double path and the balustrade 11 on the outward path to the reversing portion 11A. , 11B is configured to fold back and move. Further, indicated by reference numeral 10A on the lower side is a tension-applying roller, which gives a tensile force to a majority of the traveling length of the handrail belt 5 of the present invention.

On the other hand, in the seam portion of the display sheet, the lower end portion thereof is attached to the handrail belt, and the upper end side end portion thereof is attached so as to cover the lower side end portion. The whole is adhered with a seam material with an adhesive, and the handrail belt is applied to a configuration in which the step moves in the ascending direction, and the handrail belt is applied to the seam portion and the seam material of the display sheet. The range in which the pulling force in the moving direction acts is more than half, and the surface of the seam material is prevented from having a dent K in which peeling and dirt are accumulated. In this case, it can be expected that the tension adding roller 10A becomes unnecessary.

The display sheet 6 has a seam member 6C provided on the seam portion 66 in a state of being divided into one or a plurality of the entire length of the handrail belt 5, and the adhesive layer on the inner surface side thereof is the surface of the handrail belt 5. Along with being attached to the flat portion 5B and the semicircular portion 5B of the above, the direction display mark 6A indicating the moving direction is printed on the sheet portion layer on the surface of the display sheet 6 to the full width W2 of the flat portion 5A so as to be conspicuous. In addition, a plurality of direction display marks 6A are provided in the total length direction of the handrail belt 5 at appropriate intervals P, and a height H which is a half-circumferential range of the reversing portion of the handrail belt 5 (FIGS. 1 and 2). A plurality of them are arranged at intervals P (FIG. 4) in which at least one exists. Then, when the user (passenger) who is about to board the vehicle sees the fall prevention type escalator 1, at least one direction display mark 6A exists within the range of the code H which is always in front of the escalator 1, and the speed of movement is high. It surely appeals to the sense and the direction of movement. In addition, the direction display mark 6A is printed in yellow or white, for example, and the mark is not limited to the circle shown in FIGS. 2 and 4, but a large arrow or rhombus is not inconvenient, and its size is arbitrary. ..

Further, on the display sheet 6 attached to the handrail belt 5 of the present invention, a display unit 6B such as a cautionary statement is provided within the interval P of the direction display mark 6A as shown by the frame of the imaginary line in FIGS. 2 and 4. There are safety precautions and guidance signs such as "grab the handrail", "the left side of the exit is the ticket gate", "the right side of the exit is the subway Ginza line", and various types not shown. "Advertisement" is displayed by printing. In this case, the display sheet 6 is composed of a multi-layer material such as a laminated layer on the surface in addition to an adhesive layer to the handrail belt 5 and a sheet portion layer to be printed, which overlaps with the above.

よりも長い範囲の長さＬの継ぎ目材６Ｃで外見的には図４のように被っている。Further, the display sheet 6 attached to the handrail belt 5 of the present invention has a vertical cross section (FIGS. 3 and 4 are cross sections, whereas only the display sheet 6 attached to the handrail belt 5 is shown in FIG. 5 and below. As conceptually illustrated (a cross-sectional view in the vertical direction), the display sheet 6 attached to the entire surface of the handrail belt 5 has the configurations shown in FIGS. 5, 6, and 7. FIG. 5 shows an example in which the seam portion 66 is provided at two locations, and each of them is shown.

A seam material 6C having a length L in a longer range is covered in appearance as shown in FIG.

Here, the dent K generated when a contraction force (indicated by an arrow n in FIG. 7) acts on the handrail belt 5 with respect to the seam material 6C of the seam portion 66 (repeated contraction and pulling creates a dent K). The tension applying roller 10A is lowered so that the surface of the seam material 6C is always on the tension side so that the joint material 6C is not torn and peeled off at the starting point, or dirt is accumulated in the dent K portion) to generate tension. Originally, the tensile force of the drive roller 9 is the range of Z1 in which the pulling range that brings the pulling force to the handrail belt 5 is large (shown in FIG. 1. The range of Z3 is the pulling range because the reversing portion 11B itself has a convex shape. The range of Z2 is the push-out side of the handrail belt 5 by the drive roller 9, that is, the contraction side opposite to Z1). Since the force is applied, the majority of the total length of the running path of the handrail belt 5 is on the tension side (to create this situation, one end of the display sheet 6 is adhered to the handrail belt 5 to the end, and the other end is attached. It is considered that the configurations of FIGS. 6 and 7 that cover the end and add with the seam material 6C), so that the dent K is unlikely to occur.

Further, claim 2 of the present invention is limited to a state in which the step is in an ascending operation in which the majority of the total length of the traveling path of the handrail belt 5 is on the tension side (the side on which the pulling force acts). In this case, it can be expected that the tension adding roller 10A becomes unnecessary.

As described above, according to the present invention, the moving direction of the handrail belt is displayed in an easy-to-see manner, and it is possible to provide a comprehensive fall accident prevention type escalator having a wide range of safety effects, guidance effects, advertising effects, etc., and a seam of the display sheet 6. The life of the portion 66 can be extended and the reliability can be improved.

Although the above embodiment has been described by taking a general escalator structure as an example, it can be applied as it is to a moving walkway having no step between adjacent steps.
