Description

  The present invention relates to a structure of a handrail belt of an escalator in which a moving step forms an inclined road or a horizontal road for passenger transportation.

Conventionally, the present inventor has already proposed a configuration in which a wide pressure-sensitive adhesive sheet is pasted on the surface of a handrail belt of an escalator to perform direction indication and advertisement, for example, as disclosed in Patent Document 1.
JP 2006-347764 A

The structure of the handrail belt described in the above-mentioned Patent Document 1 is from the filing date to today.
1) Turning and peeling occur frequently due to the “peeling action (tampering)” on the edge of the adhesive sheet (both edges of the handrail belt) by the passenger.
2) At that time, since the adhesive sheet is wide, the safety device of the escalator is operated to generate a stop event that causes a fall accident.
There was a problem.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide a configuration suitable for preventing turning and peeling due to tampering with the adhesive sheet provided on the surface of the handrail belt. is there.

  In order to achieve the above object, the present invention provides an escalator including a handrail belt having a substantially C-shaped cross section, which is reversed and moved from a forward path to a return path, and whose surface is formed by a flat portion and both edges. A wide first adhesive sheet covering both the flat part and both edges, and a narrow second adhesive sheet which is pasted so as to cover part of the edge part and both edges of the first adhesive sheet. An adhesive sheet is provided.

  In the present invention configured as described above, the end portion of the wide first adhesive sheet that is easily peeled off by being tampered with is covered and protected by the narrow second adhesive sheet, so that it is not turned over or peeled off. (Even if the end of the second adhesive sheet is peeled off, it is said that the possibility of operating the safety device is low because it is narrow).

  According to the present invention, it is possible to eliminate factors related to passenger danger such as a sudden stop caused by providing an adhesive sheet on the surface of the handrail belt.

  Hereinafter, an embodiment of a handrail belt for an escalator according to the present invention will be described with reference to FIGS.

  A general escalator 1 includes a main frame 3 mounted on an upper floor 2A and a lower floor 2B, a number of steps 4 connected endlessly and moving in an inverted manner from the forward path to the return path, and both sides of the step 4 There is a handrail belt 5 provided in a pair on the left and right and reversing and moving synchronously with the step 4, and this handrail belt 5 is substantially C-shaped in cross section with a flat portion 5A and both edge portions 5B on both sides. It has a shape to make. The position of the wide and long first pressure-sensitive adhesive sheet 6A with the direction indication mark 6a attached to the flat portion 5A (width W1) and both edge portions 5B of the handrail belt 5 is up to about half of both edge portions 5B. It is affixed to.

  The handrail belt 5 is frictionally driven by the power transmitted from the drive gear 7 to the drive roller 9 or the like via the chain 8, and is guided to the guide roller 10 on the return path and guided to the balustrade 11 on the forward path, and the reversing portion 11A. , 11B is folded and moved.

  Further, the details of the first adhesive sheet 6A are direction indication marks that are provided with a direction indication mark 6a (shown only on the right side in FIG. 2) by printing or are directly applied to the surface of the handrail belt 5. In this case, it functions as a protective coating for the display mark, but in any case, the direction display mark 6a makes the direction and speed of the handrail belt 5 appeal to the passenger's sight and is reversed by the effect. It aims to prevent accidents and falls. In addition, a plurality of direction indication marks 6a are arranged at a fixed interval of at least one in the semicircular range H (FIGS. 1 and 2) of the reversal portion of the handrail belt 5, and it is now assumed When the user (passenger) sees the escalator 1, it becomes a form displayed in the front direction, and is arranged to further enhance the visual recognition effect.

  Further, the narrow second adhesive sheet 6B, which is the main object of the present invention, is a narrow long material that is attached to the vicinity of the end of the first adhesive sheet 6A and a part of both edges 5B. , Its main purpose is to cover the vicinity of the end portion, thereby aiming at the role of preventing mischief such as peeling off with a toe. As a result of repeated trials by the inventor, it is preferable that the width is about 20 mm, the overlap in the vicinity of the end portion is halved, and the overlap on both edges 5B is approximately halved. Company: Overlaminate film (thickness of about 0.2 mm)] is judged to be optimal in terms of life.

Here, since the first pressure-sensitive adhesive sheet 6A is wide, the safety device existing in the moving path of the handrail belt 5 and the danger thereof have been described above, but the second pressure-sensitive adhesive sheet 6B having a narrow width is described above. Even if it is peeled off by mischief, the above-mentioned problems are unlikely to occur.
Moreover, since the time which rides on the escalator 1 is a short time of a second or a minute unit, it is judged that it does not lead to the act which peels off the 2nd adhesive sheet 6B and then peels off the 1st adhesive sheet 6A.

  As described above, according to the present embodiment, compared with the conventional method, the sudden stop event is greatly reduced and the direction display or the advertising effect is a negative factor (the second adhesive sheet 6B is narrow and has a flat portion 5A. It is possible to provide a handrail belt for escalators that does not get in the way.

  In the above embodiment, a general escalator has been described as an example. However, the present embodiment can also be applied to an escalator commonly referred to as a moving sidewalk having no steps on adjacent steps.
