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 including a device for cleaning or sterilizing a handrail belt is considered. However, the assembly of a special cleaning and sterilizing device in a newly installed escalator requires a large-scale installation and construction, and also costs a lot.
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.

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. Inside the outer cover 14 (inside the truss), the handrail 17 moves so that the central plane portion 21 faces downward as shown in fig. 2.
Since the handrail 17 is an indefinite portion that a plurality of users directly contact, bacteria, viruses, and the like may adhere to the handrail. Hereinafter, a method of easily attaching a sterilizing device to the existing escalator 11 and sterilizing the handrail 17 will be described.
Fig. 3 is a side view schematically showing a structure in the vicinity of one entrance of the escalator 11. In the example of fig. 3, the shape of the outer cover 14 is simplified. FIG. 4 is a front view schematically showing the structure of the bacteria removing apparatus in the X-X direction of FIG. 3.
The sterilization device 31 of the present embodiment is attached to the outer cover 14 through an insertion port 30 (dotted line portion in fig. 1) formed in the upper surface of the outer cover 14. The insertion port 30 is formed by a worker on site after the escalator 11 is attached, in accordance with the size of the sterilizing device 31.
As shown in fig. 3 and 4, the bacteria removing apparatus 31 includes a power supply unit 32, an arm unit 33, and an irradiation unit 34. The power supply unit 32 is mounted on the upper surface of the outer cover 14 provided on the outer side in the width direction than the handrail 17. The power supply unit 32 has a replaceable secondary battery 32a, and supplies electric power necessary for driving the irradiation unit 34 via a lead 36.
The arm member 33 is extended from one end side of the power supply portion 32 by a predetermined length, and is inserted into the outer cover 14 along the vertical direction through an insertion port 30 formed in the upper surface of the outer cover 14. The length of the arm member 33 is designed to be longer than the distance from the upper surface of the outer cover 14 to the handrail 17 in the outer cover 14.
The irradiation portion 34 is attached to the distal end portion of the arm member 33. The irradiation unit 34 has a plurality of light emitters 35a to 35f arranged in the width direction of the handrail 17, and irradiates germicidal light onto the surface of the handrail 17 moving inside the outer cover 14. In the example of fig. 1, 6 light-emitting bodies 35a to 35f are shown, but the number of light-emitting bodies is not limited to 6. The light-emitting bodies 35a to 35f are light-emitting elements such as leds (light emitting diodes), for example, and irradiate the surface of the handrail 17 with sterilizing light including at least ultraviolet rays. Further, although there is a method of spraying a sterilization liquid to the handrail 17, since the spraying of the liquid may deteriorate members such as the handrail 17, it is preferable to perform sterilization (sterilization) by irradiation with light.
Here, as shown in fig. 4, irradiation unit 34 is attached to tip end 33a of arm member 33 so as to be inclined at a predetermined angle θ. The angle θ is greater than 90 degrees (horizontal state) and less than 180 degrees (vertical state). This is because, when the irradiation portion 34 is horizontally attached to the tip end portion of the arm member 33 (θ is 90 degrees), the irradiation portion 34 comes into contact with the handrail 17 when the arm member 33 is inserted into the outer cover 14 from the insertion port 30. On the other hand, when the irradiation portion 34 is vertically attached to the tip end portion of the arm member 33 (θ is 180 degrees), the irradiation surface of the irradiation portion 34 does not face the handrail 17, and the sterilizing light cannot be efficiently irradiated.
Therefore, as shown in fig. 4, the irradiation portion 34 is installed at an inclination angle θ so that the irradiation surface of the irradiation portion 34 faces the flat surface portion 21 of the handrail 17 in the outer cover 14. When the bacteria removing device 31 is mounted, the arm member 33 is inserted into the outer cover 14 from a position slightly distant from the handrail 17, and then the power supply portion 32 is shifted in the arrow a direction (the direction of the handrail 17) so that the irradiation surface of the irradiation portion 34 approaches the flat surface portion 21 of the handrail 17. After the mounting, the power supply unit 32 is fixed to the surface of the outer cover 14 by bolts or the like, and covers a cover 37 as shown in fig. 3.
In this way, the sterilizing device 31 can be easily attached by a simple operation of digging out the insertion port 30 on the surface of the outer cover plate 14. The bacteria removing device 31 is provided inside the outer cover 14, and therefore does not interfere with the riding and descending operation of the user and does not catch the hand of the user. Further, the power supply unit 32 placed on the outer cover 14 is covered with the cover 37, thereby preventing the user from touching the power supply unit 32.
The secondary battery 32a used in the power supply unit 32 can be replaced, and when the remaining battery capacity is insufficient or deteriorated, the secondary battery can be replaced with a new one as needed. In addition, the power supply unit 32 may be provided with a charging terminal and may be directly charged by a commercial power supply, a charger, or the like.
For example, the sterilization device 31 is activated by an operation of a power switch, not shown, provided in the power supply unit 32. During the operation of the escalator 11, the sterilizing device 31 is preferably operated all the time. Further, there is also a method of starting the sterilizing device 31 in conjunction with the operation of the escalator 11, but wiring work for connecting the sterilizing device 31 to a control device in a machine room, not shown, is required. Thus, the sterilizing device 31 is preferably activated solely by the operation of the power switch.
For example, as shown in fig. 5, a motion sensor 40 may be provided near the power supply portion 32, and when the motion sensor 40 detects the movement of the handrail 17 or the steps 12, the power switch may be automatically turned on to start the bacteria removing device 31. When the sterilizing device 31 is activated, as shown in fig. 4, sterilizing light is irradiated from the light emitters 35a to 35f of the irradiation unit 34 toward the handrail 17. Thereby, bacteria and viruses adhering to the handrail 17 are removed and are then taken out from the entrance 24 of the upper or lower floor.
The sterilizing device 31 can be installed near the entrance of the upper floor or the lower floor regardless of the running direction of the escalator 11. For example, as shown in fig. 1, the bacteria removing device 31 is provided in the vicinity of the entrance of the lower floor (specifically, in the outer cover 14 in the vicinity of the entrance). In this case, during the ascending operation, the handrail 17 sterilized by the irradiation portion 34 is pulled out from the entrance 24 of the lower layer. Therefore, the user who takes the escalator 11 from the lower floor can take hold of the handrail 17 after sterilization and move to the upper floor.
On the other hand, during the lowering operation, the handrail 17 sterilized by the irradiation portion 34 passes through the inside of the outer cover 14 and exits from the entrance 24 of the upper deck. In this case, the bacteria removing effect does not disappear while the handrail 17 passes through the outer panel 14. Therefore, the user who rides the escalator 11 from the upper floor can take hold of the handrail 17 after sterilization and go to the lower floor.
(deformation line)
(1) As described above, the irradiation portion 34 of the sterilizing device 31 is attached to the arm member 33 while being inclined at the predetermined angle θ. Therefore, as shown in fig. 4, the irradiation surface of the irradiation portion 34 does not face the handrail 17 in the horizontal direction, and there is a possibility that the sterilizing light cannot be uniformly irradiated to the surface of the handrail 17.
Therefore, as shown in fig. 6, the irradiation force of the light emitters 35a to 35f may be independently adjusted in consideration of the inclination of the irradiation portion 34, and the irradiation force may be increased in stages from the side close to the handrail 17. Further, for example, the irradiation force can be adjusted by adjusting the currents flowing through the light emitters 35a to 35 f. In the example of fig. 6, the thickness of the arrow indicates the intensity of the irradiation force.
For example, when the light emitters 35a to 35f are divided into three groups, the irradiation power of the light emitters 35a and 35b in the 1 st group is adjusted to level 1, the irradiation power of the light emitters 35c and 35d in the 2 nd group is adjusted to level 2, and the irradiation power of the light emitters 35e and 35f in the 3 rd group is adjusted to level 3 (level 1< level 2< level 3). This allows the sterilizing light to be uniformly irradiated onto the surface of the handrail 17, including the portion (the side portion 22b of the handrail 17) distant from the irradiation portion 34.
(2) As another method, as shown in fig. 7, the irradiation directions of the light emitters 35a to 35f may be independently adjusted in consideration of the inclination of the irradiation unit 34. Further, the irradiation direction can be adjusted by adjusting the installation angles of the light-emitting bodies 35a to 35f, or by adjusting the directions of the sterilizing light irradiated from the light-emitting bodies 35a to 35f using polarizing plates or the like, for example. In the example of fig. 7, the direction of the arrow indicates the irradiation direction.
For example, when the light emitters 35a to 35f are divided into three groups, the sterilizing light of the light emitters 35a and 35b of the 1 st group is irradiated toward the side portion 22a of the handrail 17. The germicidal light from the illuminants 35c, 35d of the 2 nd group is radiated toward the flat surface portion 21 of the handrail 17, and the germicidal light from the illuminants 35e, 35f of the 3 rd group is radiated toward the side portion 22b of the handrail 17. This allows the sterilizing light to be uniformly irradiated onto the surface of the handrail 17, including the both side portions 22a and 22b of the handrail 17.
(3) Further, the method of the above (1) may be combined with the method of the above (2), and as shown in fig. 8, the irradiation force and the irradiation direction of the light emitters 35a to 35f may be independently adjusted in consideration of the inclination of the irradiation portion 34. In the example of fig. 8, the thickness of the arrow indicates the intensity of the irradiation power, and the direction of the arrow indicates the irradiation direction.
For example, when the light emitters 35a to 35f are divided into three groups, the irradiation force of the light emitters 35a and 35b of the 1 st group is adjusted to level 1 and is irradiated toward the side portion 22a of the handrail 17. The irradiation power of the illuminants 35c, 35d of the 2 nd group is adjusted to level 2 and irradiated toward the plane portion 21 of the handrail 17. The irradiation power of the illuminants 35e, 35f of the 3 rd group is adjusted to level 3 and is irradiated toward the side portion 22b of the handrail 17. This allows the sterilizing light to be uniformly irradiated onto the surface of the handrail 17, including the both side portions 22a and 22b of the handrail 17.
In the above-described embodiment, the case where the sterilizing device 31 is attached to one of the outer side covers 14 on both sides of the escalator 11 has been described, but the same sterilizing device 31 may be attached to the other outer side cover 14 to irradiate the other handrail 17 moving in the outer side cover 14 with the sterilizing light. Therefore, the user can move the handrail 17 while holding the handrail 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 31 are provided on both sides of the escalator 11, it is preferable to provide the sterilizing devices 31 on both sides of the escalator 11 on the lower floor or the upper floor as shown in fig. 9 in consideration of the efficiency of the installation work. Fig. 9 shows an example in which the sterilizing devices 31 are provided on both sides of the escalator 11 in the lower stage.
As shown in fig. 10, the sterilizing device 31 may be provided on one side (for example, the left side) of the escalator 11 on the lower floor, and the sterilizing device 31 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. 11, 4 sterilizing devices 31 may be used, and the sterilizing devices 31 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 and the like as long as a handrail belt is provided, and can obtain the same effects as those of the above-described embodiments.
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.
The present invention is not limited to the embodiments described above, but various modifications can be made without departing from the scope of the present invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the present invention. These embodiments and modifications are included in the scope and gist of the utility model, and are included in the utility model described in the claims and the scope equivalent thereto.
