Description
This application is based on Japanese patent application No. 2020-206050 (filing date: 12/2020/11), which is entitled to the priority of this application. This application incorporates by reference the entirety of this application.
Technical Field
Embodiments of the present invention relate to a degerming device for passenger conveyors such as escalators and moving walkways.
Background
Generally, a handrail belt is provided on a pair of left and right balustrades of an escalator, and the handrail belt moves cyclically together with the movement of steps. The handrail belt is provided as a safety measure for preventing a user from falling down. However, the handrail belt is a portion that is directly contacted by an indefinite number of users, and there are many users who do not hold the handrail belt.
Therefore, an escalator provided with a device for cleaning or sterilizing a handrail can be considered. However, assembling a special device for cleaning and sterilizing in a newly installed escalator requires a large-scale installation and construction, and also requires a high cost.
In recent years, along with the spread of highly contagious viruses, there has been a demand for a sterilizing apparatus that can be easily attached to an existing escalator. In this case, for example, a method of externally attaching a sterilizer to a curved portion of the handrail near the entrance is generally employed. However, when the bacteria removing device is externally installed, there is a risk that the user's hand is caught between the handrail and the bacteria removing device.
SUMMERY OF THE UTILITY MODEL
The to-be-solved problem of the present invention is to provide a bacteria removing device for a passenger conveyor, which can be simply installed in an established passenger conveyor without requiring a large-scale setting construction, and which can effectively remove bacteria without worrying about the hand of a user being involved.
A degerming device for a passenger conveyor of one embodiment is used for the passenger conveyor with a handrail belt, wherein the handrail belt is arranged between a 1 st landing port and a 2 nd landing port and circularly moves together with a plurality of steps. The sterilization apparatus includes a light guide plate, an irradiation unit, and a driving unit. The light guide plate is arranged in parallel with the surface of the handrail moving in the entrance of the passenger conveyor with a certain interval. The irradiation part is arranged at one end part of the length direction of the light guide plate and irradiates sterilizing light to the surface of the handrail belt through the light guide plate. The driving unit drives the irradiation unit.
According to the bacteria removing device for the passenger conveyor with the above configuration, the bacteria removing device can be easily attached to an existing passenger conveyor without requiring large-scale installation and construction, and can effectively remove bacteria without worrying about the hands of a user being involved.

Detailed Description
Hereinafter, embodiments will be described with reference to the drawings.
In the following, an escalator, which is one of the passenger conveyors, will be described as an example. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and the repetitive description thereof will be appropriately simplified or omitted.
Fig. 1 is a perspective view partially showing a configuration of an escalator according to an embodiment. Reference numeral 11 in the drawings denotes an escalator as a whole. The escalator 11 is disposed, for example, obliquely between an upper floor and a lower floor of a building. Fig. 2 is a front cross-sectional view showing a structure of a handrail belt for an escalator.
As shown in fig. 1, the escalator 11 in the present embodiment includes a plurality of steps 12, and a pair of balustrades 13 erected on both sides of the steps 12. Each step 12 is formed of, for example, cast aluminum, and circulates between the 1 st landing port (e.g., the upper landing port) and the 2 nd landing port (e.g., the lower landing port). An outer cover (outer cover) 14 and an inner cover (inner cover) 15 are provided below the pair of balustrades 13 so as to sandwich the balustrade panel 16. The balustrade panel 16 is formed of, for example, transparent glass, acrylic, or the like, and a handrail 17 whose periphery is covered with rubber or the like is provided at the peripheral edge portion of the balustrade panel 16. The handrail belt 17 circulates between the entrance and the exit in synchronization with the steps 12, and is taken out from the entrance 24 on the entrance side to the outside and taken into the outer cover 14 from the entrance 24 on the exit side.
Here, the handrail 17 will be explained.
As shown in fig. 2, the handrail 17 is made of rubber or urethane and has a C-shaped cross section. The handrail 17 includes a central planar portion 21 and a pair of left and right side portions 22a, 22b extending so as to be bent from the left and right sides of the planar portion 21. The handrail belt 17 is supported by the handrail rails 23 and moves cyclically between the entrance and the exit. In detail, the outer cover 14 is a portion surrounded by the front skirt guard 25 and the outer skirt guard 26 shown in fig. 1. When the handrail 17 is pulled in from the entrance 24 of one side (for example, the lower floor) in the longitudinal direction of the escalator 11, as shown in fig. 2, the central flat surface portion 21 moves downward, and the handrail passes through the outer cover 14 and is pulled out from the entrance 24 of the other side (for example, the upper floor). The handrail 17 that has been pulled out from the other entrance 24 moves on the balustrade 13 so that the central flat portion 21 faces upward.
Here, since the handrail 17 is an indefinite portion that a plurality of users directly contact, bacteria, viruses, and the like may be attached. As will be described later, in the present embodiment, a light guide plate 32 is provided in the entrance 24, and the handrail 17 is irradiated with sterilizing light through the light guide plate 32.
Hereinafter, a method of simply installing a sterilizing apparatus to the existing escalator 11 to sterilize the handrail 17 will be described.
Fig. 3 is a perspective view showing the structure of the bacteria removing device of the present embodiment. Fig. 4 is a side view schematically showing the configuration inside the entrance 24 of the escalator 11.
As shown in fig. 3, the bacteria removing device 30 of the present embodiment has an L-shaped device main body 31, and the device main body 31 is provided with a light guide plate 32, an irradiation unit 33, a drive unit 34, and a cover member 35. The light guide plate 32 is a thin surface light emitting plate that diffuses light entering from the side surface and emits uniform light from the surface. In a normal state, the handrail 17 is in a straight line shape inside the entrance 24, and moves while being bent inside the cover plate via a guide roller not shown. The light guide plate 32 is disposed in the entrance 24 where the handrail 17 is linear.
Specifically, as shown in fig. 4, devices 27 such as an inlet switch, not shown, are provided in the inlet 24, and the space for installing the light guide plate 32 is limited. The light guide plate 32 is arranged in parallel with the handrail 17 at a predetermined interval while avoiding the devices 27. Here, the length L (the dimension in the longitudinal direction) of the light guide plate 32 is preferably as follows: within the above-described space, the length of the handrail 17 that can be effectively sterilized depends on the relationship between the moving speed and the irradiation time of the sterilizing light. The lateral width W (dimension in the short side direction) of the light guide plate 32 is preferably the same as or slightly wider than the lateral width of the handrail 17.
The surface of the light guide plate 32 (the surface facing the handrail 17) is subjected to a frosting process for diffusing the sterilizing light. The germicidal light includes at least ultraviolet rays. There is also a method of spraying a sterilizing liquid onto the handrail 17, but since the spraying of the liquid may deteriorate members such as the handrail 17, it is preferable to perform sterilization (sterilization) by irradiation of light. However, when ultraviolet light is irradiated as the sterilizing light, there is a possibility that a resin material such as an inlet switch may be deteriorated. Therefore, it is preferable that the cover member 35 through which the germicidal light cannot pass is covered except for the surface of the light guide plate 32 on which the germicidal light enters (the installation surface side of the irradiation portion 33) and the surface (front surface) facing the handrail 17.
The illumination section 33 is provided at one end in the longitudinal direction of the light guide plate 32, and includes a plurality of light emitters 33a to 33 c. The light emitters 33a to 33c are arranged along the short side direction of the light guide plate 32, and irradiate germicidal light toward one end of the light guide plate 32. In the example of fig. 3, 3 light emitters 33a to 33c are shown, but the number of light emitters is not limited to 3. As the light-emitting bodies 33a to 33c, for example, leds (light emitting diodes) are used, and sterilizing light including at least ultraviolet rays is irradiated.
The device main body 31 incorporates a drive unit 34 for driving the light emitters 33a to 33c to emit light. The driving unit 34 receives necessary power from a power supply unit, not shown, via a power supply line 36, and drives the light emitters 33a to 33c to emit light.
When the bacteria removing device 30 is mounted on the escalator 11, an inlet cover (not shown) is removed, and the surface (irradiation surface) of the light guide plate 32 of the bacteria removing device 30 is directed upward and arranged parallel to the handrail 17 at the lower portion of the handrail 17 moving through the inlet 24. The degerming device 30 is fixed to a truss or the like, not shown, by the attachment fittings 37 while the distance between the handrail 17 and the light guide plate 32 is kept constant.
In this state, when the power supply line 36 is connected to a power supply unit, not shown, and power is supplied to the drive unit 34, the light emitters 33a to 33c of the irradiation unit 33 emit light, and the surface of the handrail 17 is irradiated with germicidal light via the light guide plate 32. Since the surface of the light guide plate 32 is frosted as described above, the germicidal light is uniformly irradiated from the surface of the light guide plate 32 toward the surface of the handrail 17. This enables bacteria and viruses adhering to the handrail 17 to be effectively removed.
As described above, according to the present embodiment, the light guide plate 32 can be used to easily install the bacteria removing device 30 in a limited space in the inlet 24. The bacteria removing device 30 is provided inside the entrance 24, and therefore does not interfere with the riding and descending operation of the user and does not catch the hand of the user.
During the operation of the escalator 11, the sterilizing device 30 is preferably operated all the time. Further, there is also a method of starting the sterilizing device 30 in conjunction with the operation of the escalator 11, but wiring work for connecting the sterilizing device 30 to a control device in a machine room, not shown, is required. Therefore, for example, it is preferable that a power switch, not shown, is provided in the apparatus main body 31, and the sterilizing apparatus 30 is individually started by operating the power switch.
The sterilizing device 30 can be provided in the entrance 24 of the upper or lower floor regardless of the running direction of the escalator 11. For example, as shown in FIG. 1, assume that the bacteria elimination device 30 is disposed within the lower inlet 24. In this case, during the ascending operation, the handrail 17 sterilized by the sterilizing device 30 is carried out from the entrance 24 of the lower layer. Therefore, the user who takes the escalator 11 from the lower floor can grip the handrail 17 sterilized by the sterilizing device 30 and move to the upper floor.
On the other hand, during the lowering operation, the handrail 17 sterilized by the sterilizing device 30 passes through the inside of the outer cover 14 and exits from the entrance 24 of the upper deck. In this case, the bacteria elimination effect does not disappear while the handrail 17 passes through the outer cover 14 (inside the truss). Therefore, the user who rides the escalator 11 from the upper floor can grip the handrail 17 after sterilization and move to the lower floor.
(modification example)
As shown in fig. 2, the handrail 17 moves in the entrance 24 so that the central plane portion 21 faces downward. Here, the surface (irradiation surface) of the light guide plate 32 of the bacteria removing device 30 faces the flat surface portion 21 of the handrail 17. Therefore, the germicidal light is uniformly irradiated to the flat portion 21 of the handrail 17 through the light guide plate 32, but the germicidal light may not be irradiated to both side portions 22a and 22b of the handrail 17.
Therefore, as shown in fig. 5, for example, a flexible light guide plate that can be flexibly bent is used as the light guide plate 32, and the light guide plate 32 is assembled to the apparatus main body 31 in a state where both side portions 32a and 32b in the width direction of the light guide plate 32 are bent outward of both side portions 22a and 22b of the handrail 17. In this case, it is also preferable that the cover member 35 through which the germicidal light does not pass is covered on the surface of the light guide plate 32 on which the germicidal light is incident (the installation surface side of the irradiation section 33) and the surface (front surface) facing the handrail 17. By using such an arcuate light guide plate 32, the sterilizing light can be uniformly irradiated not only to the flat portion 21 of the handrail 17 but also to the both side portions 22a and 22 b.
In the above-described embodiment, the case where the sterilizing device 30 is installed in one of the entrances 24 on both sides of the escalator 11 has been described, but it is also possible to install the same sterilizing device 30 in the other entrance 24 and irradiate the other handrail 17 moving in the entrance 24 with sterilizing light. Therefore, the user can move while holding the handrail 17 after the sterilization regardless of whether the user stands on one side (for example, the left side) or the other side (for example, the right side) of the escalator 11.
Here, in the case where the sterilizing devices 30 are provided on both sides of the escalator 11, it is preferable to provide the sterilizing devices 30 on both sides of the escalator 11 on the lower floor or the upper floor as shown in fig. 6 in consideration of the efficiency of the installation work. Fig. 6 shows an example in which the sterilizing devices 30 are provided on both sides of the escalator 11 in the lower stage.
As shown in fig. 7, the sterilizing device 30 may be provided on one side (for example, the left side) of the escalator 11 on the lower floor, and the sterilizing device 30 may be provided on the other side (for example, the right side) of the escalator 11 on the upper floor. Further, as shown in fig. 8, 4 sterilizing devices 30 may be used, and the sterilizing devices 30 may be provided on both sides of the lower escalator 11 and both sides of the upper escalator 11.
The present invention is not limited to escalators, and can be applied to all passenger conveyors including moving walkways as long as a handrail belt is provided, and can obtain the same effects as those of the above-described embodiment.
According to at least one embodiment described above, it is possible to provide a bacteria removing device for a passenger conveyor, which can be easily attached to an existing passenger conveyor without requiring a large-scale installation work, and which can effectively remove bacteria without fear of a user's hand being caught in the bacteria removing device.
While the present invention has been described with reference to several embodiments, these embodiments are presented as examples and are not intended to limit the scope of the present invention. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
