Description

  The present invention relates to a configuration of an escalator handrail belt or the like in which passengers are transported by a moving step forming an inclined road or a horizontal road.

  Conventionally, the structure which sticks a printing sheet on the handrail belt surface of an escalator and performs advertisement display has already been proposed as disclosed in, for example, Patent Document 1.

  The handrail belt of the escalator described in Patent Document 1 is such that a print sheet displaying only an advertisement is pasted in the longitudinal direction of the surface of the handrail belt.

JP 2003-212468 A

  The thing of the said patent document 1 mainly aimed at provision of an advertising medium so that there may be "the printed sheet of the advertising material was stuck on the surface longitudinal direction of the moving handrail" in Claim 1 at the time of the application. Therefore, there was no idea of the safety effect such as the fall prevention for the passengers, the maintenance of the aesthetics and the prevention of the peeling phenomenon by this printed sheet.

  On the other hand, with the recent use of escalators, due to the aging of the user base, there are a number of accidents that fall due to loss of the timing of weight shift when changing to a step that moves on the escalator platform. This is due to the fact that the color of the step staring at the transfer is dark and the movement (speed) of the step cannot be recognized. In addition, there is a phenomenon that the direction of movement of the escalator cannot be recognized, and reverse boarding is performed. Furthermore, the printing sheet described in Patent Document 1 is simply provided with characters and designs. When the handrail belt is moving, the characters and designs look as if they are a single band, and the direction display function is exhibited. In addition, there is a problem that the surface of the printing sheet is prematurely soiled due to electrostatic charging, and further, there is a problem that the end portion of the printing sheet is peeled off.

  An object of the present invention is to display the direction of movement of the handrail belt on the surface of the handrail belt in an easy-to-see manner, thereby preventing a fall accident and the like, and preventing the surface of the printing sheet from being damaged due to electrostatic charging and from peeling off the end. It is to provide an escalator configured.

  In order to achieve the above object, the present invention reverses and moves from the forward path to the return path, transports passengers, and a handrail belt having a substantially C-shaped cross section that reverses and moves from the forward path to the return path in synchronization with this step. In the escalator, a long print sheet covering almost the entire outer peripheral surface of the handrail belt having a substantially C-shaped cross section is attached to the handrail belt, and an end portion of the print sheet attached to the return path of the handrail belt A plurality of roller members made of a conductive material that are always in contact with the roller are arranged.

  In this way, the presence of the direction indication mark on the surface of the handrail belt to indicate the moving direction of the handrail belt allows the user (passenger) who gets into the escalator to visually recognize the moving speed and direction of the escalator. As a result, it is easy to take the timing of getting on the step and is useful for preventing reverse boarding. In addition, by making the roller body in contact with the handrail belt surface conductive in the return path of the handrail belt, the roller body is charged by static electricity, thereby preventing dust from adhering to the print sheet. There is an effect that it is not transferred. Further, by always contacting a roller body made of a conductive material to the end portion of the print sticker in the return path of the handrail belt, it is possible to prevent peeling from the roller body.

  ADVANTAGE OF THE INVENTION According to this invention, while preventing the fall accident by the failure of taking-in timing to an escalator, it can prevent the printing sheet which is the surface of a handrail belt from being damaged, and can also prevent peeling from the sticking edge part.

  Hereinafter, an embodiment of a handrail belt of an escalator according to the present invention will be described based on the escalator shown in 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 an outward path to a return path, The handrail belt 5 having a width W1 having a substantially C-shaped cross section is formed by a flat portion 5A and a semicircular portion 5B on both edges connected to the flat portion 5A. A long printing sheet 6 is provided along the longitudinal direction of 5 and bonded and fixed (not shown) so as to cover almost the entire outer peripheral surface from the flat portion 5A (width W2) to the semicircular portion 5B. Yes.

  The handrail belt 5 is frictionally driven by the power transmitted from the drive gear 7 to the drive roller 9 and the like through the chain 8, and is guided by the roller body 10 for guidance on the return path and reversed by the balustrade 11 on the forward path. The parts 11A and 11B are folded and moved.

  Further, the print sheet 6 is affixed to the entire length of the handrail belt 5, and the direction indication mark 6A for displaying the moving direction is printed on the surface layer so that the width W2 of the flat portion 5A is full or larger so as to be easily noticeable. On the other hand, at least one interval P (FIG. 4) exists in the semicircular range H (FIGS. 1 and 2) of the reversal part of the handrail belt 5 and is now arranged. When the user (passenger) who is getting on the escalator 1 looks at the escalator 1, the direction display mark 6 </ b> A that is always within the range of the reference sign H always appeals to the sense of speed and direction of movement. To demonstrate. In addition, the direction indication mark 6A is different in color from the ground color of the print sheet 6 (for example, yellow), and the mark is not limited to the rhombus illustrated in the drawing, and there is no problem even with a large arrow or oval mark. Further, in the interval P, there is provided a display section 6B that displays a warning character (for example, “no walking”) or an advertisement with a width W3 narrower than the width of the direction display mark 6A (width W2).

  Here, since the roller body 10 that is in contact with the surface of the handrail belt 5 in the return path of the handrail belt 5 is conventionally made of an insulating material and a non-conductive synthetic resin material, the handrail belt 5 and the printing sheet are used. As the roller body 10 is charged with static electricity due to friction with the roller 6, dust floating around the roller body 10 is collected, and this dust is transferred to the surface of the print sheet 6. As a result, the handrail belt 5 or the print sheet 6 is soiled. I was letting. Therefore, in the present invention, the roller body 10 is made of a conductive material (for example, an aluminum alloy) to prevent electrification. On the return path of the handrail belt 5, a roller body 12 made of a conductive material is provided in the vicinity of the handrail belt 5 entering and exiting the inside of the machine. A plurality of arrangements (shown in FIG. 1) are arranged so as to be in constant contact (shown in FIG. 5) with the end of the print sheet 6 in the width direction. Here, the roller body 12 is made of, for example, an aluminum alloy and has a surface portion 12AA of the anodized layer, while the bearing 12A and the shaft 12B of the roller body 12 are each made of metal that is a conductive material.

  As described above, the roller body 12, the bearing 12A, and the shaft 12B are particularly made of a conductive material. Therefore, when static electricity is generated due to friction between the roller body 12, the handrail belt 5 and the print sheet 6, the static electricity is 12A and 12B are grounded to the main frame 3 side (not shown) that supports them (not shown) to eliminate static charge, thereby preventing the printing sheet 6 from being stained. Further, since the roller body 12 is always in contact with the end portion of the printing sheet 6 and presses the end portion that is easily peeled off, the roller body 12 is not peeled off from the handrail belt 5.

  Here, the details of the printing sheet 6 are formed by a laminate layer on the surface in addition to an adhesive layer to the handrail belt 5 and a sheet layer on which printing is performed.

  As described above, according to the present embodiment, the moving direction of the handrail belt 5 is displayed in an easy-to-see manner, so that it is possible to prevent a fall accident or reverse riding on the escalator, and also due to static electricity of the printing sheet 6. It can prevent fouling and peeling.

  In addition, although the said embodiment demonstrated the example of the general escalator, it can be applied as it is also to the escalator commonly called the moving walk which does not have a level | step difference between adjacent steps.
