Conventionally, handrail belts such as escalators and moving walkways come into direct contact with many people's hands. Therefore, it is desirable to perform sterilization. Furthermore, at present, as a countermeasure against coronavirus infection, it is required to completely eliminate viruses and bacteria by sterilizing parts that come into direct contact with human hands.

However, viruses, especially coronaviruses, cannot be sufficiently sterilized except by directly sterilizing the handrail belt with alcohol, etc. However, when performing alcohol sterilization, always clean the cloth that is impregnated with alcohol. and the need to keep alcohol in stock at all times.

In particular, in the case of sterilization using sterilization light such as ultraviolet rays, in order to sufficiently sterilize, it is necessary to irradiate the entire handrail belt with the sterilization light and irradiate it for a predetermined time or longer. In the device, there is a problem that the irradiation time is insufficient because the handrail belt has uneven irradiation.

In addition, it is necessary to have a structure that can be easily attached to handrail belts such as escalators, which are already in existence today.

SUMMARY OF THE INVENTION Therefore, the present invention provides a handrail belt sterilization device which can be easily attached to a handrail belt of an escalator or the like and has a structure capable of sufficiently sterilizing the handrail belt.

The present invention relates to a handrail sterilizing device for sterilizing an endless track handrail that moves along a guide part of an escalator, a moving walkway, etc., wherein the handrail extends along the raised portion of the endless track handrail to a predetermined length, and the upper end of the handrail and a frame portion having a fixed roller that contacts the endless track handrail at its lower end, a reflecting mirror portion arranged to cover the endless track handrail, and a reflecting mirror portion arranged to face the endless track handrail. and a plurality of sterilization units arranged along the frame, a fixing mechanism for fixing the fixing roller of the frame, and a cover covering the frame. be.

As a result, since the fixed roller is fixed in contact with the endless track handrail by the fixing mechanism, a plurality of sterilization units equipped with ultraviolet lamps can be arranged along the endless track handrail, so that the endless track handrail can be constructed with a simple structure. It can definitely be sterilized.

The fixing mechanism includes a rod having the fixed roller at one end and a clamp pad at the other end, a lever that presses the crank pad against the guide portion and causes the roller to contact the endless track handrail, and Preferably, it consists of a spring that applies tension to the rod.

According to this invention, since the fixed rollers can be reliably brought into contact with the endless track handrail, the frame portion having a plurality of sterilizing units can be easily and reliably installed on the endless track handrail.

Further, in the sterilization section, it is preferable that at least two ultraviolet lamps are arranged along the width direction of the endless track handrail on a heat sink fixed inside the reflecting mirror section of the frame section.

According to this invention, since at least two ultraviolet lamps are arranged along the width direction of the endless track handrail, the sterilizing light emitted by the ultraviolet lamps is reflected along the reflecting mirror portion. Since the front, side and back surfaces of the handrail can be reliably irradiated, the endless track handrail can be sterilized with certainty.

Furthermore, one of the fixed rollers of the frame portion is connected to a generator via a belt, and the rotation of the fixed roller drives the generator, and the power generated by the generator can cause the ultraviolet lamp to emit light. desirable.

According to this invention, the rotation of the fixed roller causes the generator to rotate, and the electric power generated by the generator causes the ultraviolet lamp to emit light.

With the above configuration, the handrail sterilizing device according to the present invention can be easily attached to the endless track handrail of the elevator or the like, and the endless track handrail can be irradiated with ultraviolet rays for a predetermined time over a predetermined length. , the endless track handrail can be reliably sterilized. Since the ultraviolet lamp can irradiate ultraviolet rays for a predetermined period of time, it is effective not only for bacteria but also for sterilizing viruses such as coronaviruses.

FIG. 1 is an explanatory view showing a mounting state of a handrail sterilizing device according to the present invention to an endless track handrail. FIG. 2 is an explanatory diagram showing a cross section of the sterilizing section of the handrail sterilizing device according to the present invention.

A handrail sterilizing device according to the present invention is for sterilizing endless track handrails that move along guide parts such as escalators and moving walkways. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A handrail sterilizer 1 according to an embodiment of the present invention is shown in, for example, FIG. It is for disinfecting the endless track handrail 4 moving along.

The handrail sterilizer 1 is a frame portion that extends along the raised portion 5 of the endless track handrail 4 and has fixed rollers 6 and 7 that contact the endless track handrail 4 at the upper and lower ends thereof. 8, a reflector portion 9 arranged to cover the endless track handrail 4, and an ultraviolet lamp 10 arranged in the reflector portion 9 so as to face the endless track handrail 4, and the frame portion 8 , a fixing mechanism 12 for fixing the fixed rollers 6 and 7 of the frame portion 8, and a cover portion 13 that covers the frame portion 8 as a whole. It is.

The fixing mechanism 12 includes a rod 15 having the fixed rollers 6 and 7 at one end and a clamp pad 14 at the other end, and a crank pad 14 pressed against the guide portion 3 to move the fixed rollers 6 and 7 to the infinite position. It is composed of a lever 16 that abuts on the track handrail 8 and a spring 17 that applies tension to the rod 16 . The crank pad 14 is desirably abutted and fixed to the end portion of the guide portion 3 .

As shown in FIG. 2, the sterilization section 11 includes a reflector section 9 fixed to the frame 8 and a heat sink fixed in the reflector section 9 at a position facing the upper surface portion 4C of the endless track handrail 4. 18 and at least two ultraviolet lamps 10 arranged at positions facing the endless track handrail 4 of the heat sink 18 . Reflecting surfaces are formed in the entire interior of the reflecting mirror portion 9, and in particular, the side mirror surfaces 9A, 9A for reflecting and irradiating the ultraviolet rays on the side portions 4A, 4A of the endless track handrail 4, and the endless track handrail. 4 and lower reflecting mirror surface portions 9B, 9B for reflecting and irradiating ultraviolet rays on the side lower surfaces 4B, 4B. As a result, the upper surface portion 4C of the endless track handrail 4 is directly irradiated with ultraviolet rays from the ultraviolet lamp 10, and the side portions 4A, 4A of the endless track handrail 4 are exposed to the side mirror surfaces 9A, 9A of the ultraviolet lamp 10. The ultraviolet rays reflected by the side mirror surfaces 9A and 9A and the lower folded upper surfaces 9B and 9B of the ultraviolet lamp 10 are irradiated onto the side lower surfaces 4B and 4B of the endless track handrail 4. is. Furthermore, since a plurality of the sterilization units 11 (five in this embodiment) are installed along the endless track handrail 4, irradiation of ultraviolet rays for a predetermined time can be compensated for as the endless track handrail 4 moves. is possible.

Furthermore, the fixed roller 7 fixing one side of the frame portion 8 is connected to the generator 21 via the belt 20 . As a result, the generator 21 is driven by the rotation of the fixed roller 7 of the endless track handrail 4, and the power generated by the generator 21 can be used to cause the ultraviolet lamp 10 to emit light, eliminating wiring for supplying power. It is possible.

The handrail sterilizing device 1 according to the present invention having the above configuration can be easily attached to the escalator 2 or the like, and can irradiate the endless track handrail 4 with ultraviolet rays for a predetermined time, so that viruses and sterilization can be reliably sterilized. It is possible.
