Further, there is employed a polyester-based urethane resin material such that surface layers of the print sheets are higher in friction coefficient and viscosity than surface layers of the handrail belts 6, and cleaning is carried out through processes of adsorbing and transferring dirt components on surfaces of guide rollers to the print sheets while the handrail belts 6 and print sheets 6AA are rotated, and artificially wiping the transferred dirt components away in an ongoing way.

Description

  The present invention relates to a configuration of a handrail belt of a side-by-side escalator in which a rotating step forms a horizontal path or an inclined path and mainly transports passengers in a transit form, and a cleaning method thereof.

  The provision of “Indicating the direction of belt travel by marking, etc.” was added to the “Barrier-Free Maintenance Guidelines” published by the Ministry of Land, Infrastructure, Transport and Tourism in 2007. On the other hand, the effect of improving the handrail belt utilization rate of healthy individuals as well as the convenience of visually impaired people has been evaluated. As a specific method of “marking”, the configuration described in Patent Document 1 is publicly known, and the width of the surface of the handrail belt is different from that of the handrail belt and is almost the same as the width of the surface flat portion. This is a configuration in which a printing sheet printed with an interval having at least one direction indication mark in the semicircular range of the reversing portion is pasted. In addition, as a method for removing (cleaning) dirt on the surface of the guide roller, which is said to be the cause of dirt on the surface of the handrail belt, the method described in Patent Document 2 is well known, This is a cleaning method using a specialized time and tool, limited to the cleaning work of attaching a certain length of cleaning adhesive film to remove the dirt on the guide roller.

  Patent Document 1 provides a printed sheet with a “direction indication mark” on the surface of a handrail belt, thereby visually recognizing the presence of an escalator and its sense of speed (stabilization of weight shift balance with respect to driving speed during boarding, etc.). It is effective. In fact, in March 2012, when the actual usage was investigated with an escalator with a direction indicator that was installed alone in a station in the Tokyo metropolitan area, the handrail belt utilization rate (the percentage of passengers grabbing the handrail) was 10 before construction. Although it was less than 20%, it increased by nearly 20% after construction, and the walking of healthy people who are in danger of touching the visually impaired or the elderly and involving a fall (steps) The rate of running down, etc.) decreased to about 1/8, 5% compared to just over 40% before construction, and it was found that this greatly contributed to the safe use of escalators. However, the above improvement data is only for a single installation, and in a parallel installation type in which the entrance of the first escalator and the exit of the second escalator are adjacent, the first and second escalators A means of visually appealing the distinction between the first and second escalators, especially in the case of side-by-side installation, where a fall accident due to reverse boarding (for example, boarding from the exit of an ascending escalator) is not obvious, Was demanded. Furthermore, as a problem before the presence or absence of this direction indication mark, the surface of the handrail belt itself, which is made of synthetic rubber or urethane resin, or the surface of the attached printing sheet is slippery and the gripped hand is slippery. There has been a problem that the original safety function of the handrail belt, which uses the handrail belt to maintain a stable posture, is lowered. Further, Patent Document 2 is a time and tool-like method specialized for cleaning work, and simply removes dirt on the surface of the guide roller by using a printing sheet provided for safety purposes. Was not in mind about.

  The present invention has been made in order to solve the above-mentioned problems, and the one according to claim 1 has a step for rotating and rotating from the forward path on which the passenger rides to the return path inside the machine to transport the passenger, Synchronously with this step, on the surface of the handrail belt that rotates in the reverse direction from the forward path gripped by the passenger to the return path guided by a guide roller, etc., it rotates with the same width as the width of the flat surface of the handrail belt. A first escalator and a second escalator each provided with a print sheet on which a direction indication mark for displaying a direction is printed and displayed at an appropriate interval in the full length direction are arranged side by side. Side-by-side escalator in which direction indication mark positions of at least adjacent print sheets among the print sheets included in the escalator are arranged with a positional deviation distance in the entire length direction It was the handrail belt.

  According to a second aspect of the present invention, there is provided a polyester-based urethane resin material according to the first aspect, wherein the surface layer has a coefficient of friction and adhesiveness higher than those of the handrail belt surface layer. This is a handrail belt for the side-by-side escalator.

  Further, according to a third aspect of the present invention, the dirt component on the surface of the guide roller is adsorbed and transferred to the print sheet in a state where the handrail belt and the print sheet are simultaneously rotated. The cleaning method for the handrail belt of the side-by-side escalator is such that the dirt component transferred to the printed sheet is cleaned through a process of manually wiping off the outward path.

  According to the configuration of the first aspect, the direction mark position on the surface of the handrail belt provided in the side-by-side escalator adjacent to each entrance has a displacement distance in the longitudinal direction of the full length direction. The difference between both the first and second escalators can be easily recognized (differentiated), and passengers who do not use either the first or second escalator can more easily recognize the driving direction and speed of each escalator. Therefore, it can be expected to contribute to the prevention of falling accidents such as the conventional boarding from the opposite direction.

  Moreover, according to the structure of Claim 2, the polyester-type urethane which has a numerical value whose friction coefficient and adhesiveness of the surface layer of the printing sheet of Claim 1 are higher than the friction coefficient and adhesiveness of the handrail belt surface layer. Since it is made of a resin material, it is easy to slip and slip, and it is difficult to grasp with a hand and a stable posture cannot be maintained.

  Furthermore, according to the configuration of the third aspect, the dirt component on the surface of the guide roller is adsorbed and transferred to the printing sheet in a state where the handrail belt and the printing sheet are rotated, and the dirt component transferred to the printing sheet is removed. Because it is a method of cleaning through the process of wiping humans in the forward path, the dirt on the guide roller surface, which is the cause of dirt on the handrail belt surface, is limited to conventional cleaning work, specialized in time and tool. Regardless of the method, the automatic transfer to the printing sheet has the effect of maintenance that allows automatic cleaning without disassembling the escalator machine.

1 is an overall side view showing an embodiment of the present invention. It is sectional drawing which follows the XX line of FIG. It is sectional drawing which follows the YY line of FIG. It is a conceptual cross-sectional perspective view of the handrail belt and guide part of this invention.

  Hereinafter, the structure of the handrail belt of the escalator which becomes this invention, and its cleaning method are demonstrated using FIGS. 1-4.

  In the figure, a first escalator 1A as a transportation means is connected endlessly with a main frame 3 mounted on an upper floor 2A and a lower floor 2B for, for example, ascending operation, and is inverted from an outward path to a return path. A plurality of steps 4 that rotate, a balustrade 5 that stands upright on both sides of the step 4 to form a side wall, and a handrail belt 6 that rotates between both reversing portions 5A and 5B on the periphery of the balustrade 5. The handrail belt 6 is frictionally driven by the power transmitted from the drive gear 7 to the drive roller 9 and the like via the chain 8, and the forward path gripped by the passenger is the balustrade 5, and the return path through the machine is a number of guide rollers. 10 etc. Further, the second escalator 1a, which is a transportation means, has the same structure and the same name as the first escalator 1A from the lower floor 2B to the lower floor (not shown) for the descent operation, for example. 1 is attached to the first escalator 1A), and this type of installation method in which the entrances are adjacent to each other is generally referred to as a side-by-side escalator.

  The handrail belt 6 of the first escalator 1A and the handrail belt 6 of the second escalator 1a, which are the main objects of the present invention, are currently made of either synthetic rubber or urethane resin, and generally each handrail belt. 6 is manufactured endlessly by thermoforming into a substantially C-shaped cross section in which the flat portion 6a and both edge portions 6b of the surface are connected in common. Here, on the surface of the common handrail belt 6, as shown in FIGS. 1 and 2, the upper reversing portion 5A corresponding to the height H of each balustrade 5 (the lower reversing portion 5B on the opposite side is also provided) (Same as above) within a semicircular range of at least one (meaning one or more, one arrangement is illustrated in FIG. 2) and circular with a different color from the handrail belt 6 printed with an interval. Etc. (the shape is not specified), and a print sheet 6AA on which direction indication marks 6A having a shape that is easily noticeable is attached. Here, among the handrail belts 6 of the first and second escalators 1A and 1a, the direction indication mark 6A of the print sheet 6AA attached to at least the adjacent handrail belts 6 such as the left and right two in the center of FIG. The positions are separated by a positional displacement distance h (the height difference h in FIG. 2) in the longitudinal direction. In this case, the direction indication mark 6A on the surface of the pair of left and right handrail belts 6 of the first escalator 1A and the second escalator 1a may be a left-right symmetrical position as shown in FIG. The direction indication mark 6A of the adjacent handrail belt 6 in the center of FIG. 2 can be visually discriminated by providing a positional displacement distance h to visually distinguish the first and second escalators 1A and 1a. The purpose is to appeal to others. More specifically, these direction indication marks 6A cover the surface of the handrail belt 6, and both edges 6b of the entire width W1 of the handrail belt 6 with respect to the print sheet 6AA shown in FIG. Is printed over the entire width of the flat portion 6a (width W2). The direction indication mark 6A provides the same safety effect as the known example (Patent Document 1). Here, the printing sheet 6AA of the present invention will be described in detail. The printing sheet 6AA is a thin film having a total thickness t of 1 mm or less. As an example, the base material layer 6BB is a polyester-based urethane resin material, and an adhesive is provided on the inner surface thereof. The layer 6CC has a three-layer configuration including a polyester urethane resin laminate layer 6Bb on the outer surface. Further, the direction indication mark 6A is displayed by printing on the base material layer 6BB as an example, and the adhesive layer 6CC is applied to the handrail belt 6 by the adhesive layer 6CC through the primer layer M appropriately applied for cleaning together with the base material layer 6BB. On the other hand, it is rolled and pasted as shown by an arrow K. Further, when the passenger grips and touches directly with the hand, the surface of the laminate layer 6Bb has a friction coefficient (for example, index a) and adhesiveness (for example, index b) of the surface of the handrail belt 6 made of either synthetic rubber or urethane resin. ), The friction coefficient (for example, the index A) and the adhesiveness (for example, the index B) are high and have the properties of a <A and b <B. In this case, the meaning of the expression that the coefficient of friction and the adhesiveness are high means that the printed sheet 6AA has a “moist feeling” with respect to the surface of the handrail belt 6, the gripped fingers are less likely to slip, and the handrail belt 6 is more securely attached. It is that you can grab. According to the experiments by the inventors, it is judged that the friction coefficient and the adhesive property of the laminate layer 6Bb may be values that the polyester-based urethane resin material originally has, but if necessary, a rubber-based or urethane-resin-based material It is also possible to adjust the friction coefficient and the adhesiveness in a direction to increase by applying a material.

  In addition, the cleaning mechanism of the surface of the guide roller 10 by the printing sheet 6AA according to the present invention will be described. As shown in FIG. 4, taking advantage of the property that the surface of the printing sheet 6AA has a high coefficient of friction and adhesiveness. In a state in which the handrail belt 6 and the print sheet 6AA are rotated, the stain component (not shown) on the surface of the guide roller 10 is adsorbed and transferred to the print sheet 6AA, and the stain component transferred to the print sheet 6AA is This is a method of cleaning through a human wiping process on the outbound path. For this reason, the mechanical parts of the escalator 1, especially the balustrade 5, are cleaned without disassembling them by transferring the dirt on the surface of the guide roller 10, which is the main cause of dirt on the handrail belt 6, to the printing sheet 6 </ b> AA. It can have a conservation effect. That is, as shown in Patent Document 2, the direction indication mark 6A and the sliding direction are compared with the tool stand method, which is a time specialized for cleaning by sticking a cleaning adhesive film of a certain length for a certain time to remove the dirt on the guide roller. An efficient cleaning method can be provided while exhibiting the safety of difficulty. Furthermore, if aesthetics are maintained by this dirt removing effect, the number of users of the handrail belt increases, and the effect of improving the safety side can be added.

  The interval of the direction indication mark 6A is set such that when the visually impaired at the entrance floor is distant from the first and second escalators 1A, 1a, the positional displacement distance h is set in front of the escalator. It is intended that the positional deviation of at least one direction display mark 6A and the rotation direction and rotation speed of each escalator can be easily visually confirmed. Further, when the visually impaired person reaches and gets into the entrance, the viewpoint is determined by the presence of the direction indication mark 6A on the upper surface of the balustrade 5 at a position close to the height of the eyes. It can be recognized and the timing of boarding (weight shift) can be easily taken, and the consciousness to follow the speed is increased, which can contribute to the reduction of the fall accident. Furthermore, it is also possible to print and provide words, advertisements, and the like for “safe use of handrails” within the interval between the direction indication marks 6A, and the target facilities are also illustrated in the first and second examples. This is applicable not only to the escalators 1A and 1a, but also to a similar mechanism and a sidewalk that moves side by side.

  As described above, according to the above-described embodiment, it is easy to distinguish between side-by-side escalators, improving safety such as preventing reverse boarding, as well as ensuring the grip of the handrail belt of the passenger and ensuring the cleaning of the guide roller. A handrail belt of a side-by-side escalator that can contribute and a cleaning method thereof can be provided.
