(Embodiment 1)
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 is a schematic diagram showing how the sterilization device according to Embodiment 1 is used. In the figure, 1 is a handrail to be sterilized, and a grip rod 10 to be gripped by the user is fixed and supported on the side wall of a hallway, staircase, etc. ing.

The sterilization device is provided with a moving body 2 set so as to straddle a gripping rod 10 from above and moving in the lengthwise direction of the gripping rod 10. - 特許庁The illustrated mobile body 2 is configured by connecting a first body 3 and a second body 4 with a connecting body 5 . Figure 2 is a cross-sectional view taken along line II-II in Figure 1, which schematically shows the internal structure of the first body, and Figure 3 is a cross-sectional view taken along line III-III in Figure 1, which schematically shows the internal structure of the second body. be.

The first body 3 shown in FIG. 2 is intended for a gripping rod 10 with a circular cross section, and includes a thin-walled cylindrical housing 30 with a part of its circumference missing, and one drive shaft supported inside the housing 30. It comprises a wheel 31 and two driven wheels 32 .

The drive wheel 31 is supported at the center of the inner surface of the housing 30 in the circumferential direction so as to be rotatable about an axis orthogonal to the longitudinal direction and the radial direction of the housing 30 . The driving wheel 31 is connected to a moving motor 33 fixed to one side of the supporting position and driven to rotate by the moving motor 33 .

The two driven wheels 32 are supported on both circumferential ends of the inner surface of the housing 30 so as to be rotatable about axes perpendicular to the longitudinal direction and the radial direction of the housing 30 . These driven wheels 32 are biased radially inward by biasing springs 34 interposed between the respective support shafts and the inner surface of the housing 30 .

As shown in FIG. 2, the first machine body 3 as described above is set with the driving wheel 31 and the two driven wheels 32 rotating on the peripheral surface of the gripping bar 10 . The two driven wheels 32 are in elastic contact with the peripheral surface of the grip rod 10 due to the biasing force of the biasing spring 34 and are pressed against the peripheral surface. The elastic contact positions of the two driven wheels 32 are separated from the rolling contact position of the driving wheel 31 by 90° or more, respectively, and the biasing force of the biasing spring 34 pushes the driving wheels 31 against the peripheral surface of the grip bar 10. It also has a pressing effect. Therefore, the grip bar 10 is gripped by the driving wheel 31 which is in rolling contact with the peripheral surface and the two driven wheels 32 which are in elastic contact with the peripheral surface. Accordingly, it moves as indicated by the white arrow in FIG.

The peripheral surfaces of the drive wheel 31 and the driven wheel 32 are desirably provided with a non-slip treatment such as coating with a non-slip material such as rubber. A concave curved surface corresponding to the circumference of 10 is preferred. As a result, the grip rod 10 can be gripped more firmly, and the movement due to the rotation of the drive wheels 31 can be reliably performed. By making the housing 30 made of an elastic material and adding the elastic restoring force of the housing 30 to the urging force of the urging spring 34, the gripping rod 10 can be gripped more reliably.

The two driven wheels 32 are displaceable in the radial direction of the housing 30 against the bias of the biasing spring 34, and are displaced following slight changes in the shape of the grip rod 10 to maintain the elastic contact state. Therefore, the first body 3 can move over, for example, the mounting portion of the bracket 11 shown in FIG. The missing portion of the housing 30 is necessary to allow passage of the supporting legs (indicated by chain double-dashed lines in FIG. 2) that support the bracket 11 on the side wall 12. As shown in FIG.

Inside the housing 30, there are a moving motor 33, a rechargeable battery 6 that serves as a power source for ultraviolet irradiation, which will be described later, and a control unit 7 that performs control operations, which will be described later. Installed to avoid interference.

Furthermore, an obstacle sensor 35 is attached to the outside of the first body 3 as shown in FIG. The obstacle sensor 35 is, for example, an optical sensor that includes a light-emitting portion that emits light forward in the running direction and a light-receiving portion that receives reflected light from the obstacle, as indicated by an arrow. Detects the presence or absence of obstacles on the travel route, such as the fingers of the user holding the .

On the other hand, the second body 4 shown in FIG. 4 driven wheels 41 and 4 UV irradiators 42 are attached.

The three driven wheels 41 are rotatably supported on both circumferential end portions and the central portion of the inner surface of the housing 40 about axes orthogonal to the longitudinal direction and radial direction of the housing 40 . These driven wheels 41 are biased radially inward by biasing springs 43 interposed between the respective support shafts and the inner surface of the housing 40 .

The ultraviolet ray irradiator 42 is a light-emitting element or an ultraviolet lamp that emits ultraviolet rays, particularly ultraviolet rays (UV-C) having a short wavelength of 280 nm or less and having an excellent sterilizing effect. In FIG. 3, two ultraviolet irradiators 42 are fixed to the inner surface of the housing 40 between the supporting positions of the three driven wheels 41 at appropriate intervals in the circumferential direction. is configured to irradiate

As shown in FIG. 3, the second body 4 as described above is set by rolling the three driven wheels 41 on the peripheral surface of the grip rod 10 . The driven wheel 41 elastically contacts the peripheral surface of the grip rod 10 by the biasing force of the biasing spring 43, and the respective elastic contact positions are separated from each other by 90° or more. Accordingly, the grip bar 10 is gripped by three driven wheels 41 elastically contacting the peripheral surface. The second body 4 is connected to the first body 3 by a connecting body 5, is pulled by the moving first body 3 as described above, and moves along the grip rod 10 with the rolling of the driven wheels 41. be able to.

The three driven wheels 41 can be displaced in the radial direction of the housing 40 against the bias of the biasing spring 43, and are displaced following the shape change of the grip rod 10 to maintain the elastic contact state. As with the first body 3 , the body 4 can move over a shape-changing portion such as an attachment portion of the bracket 11 . The missing portion of the housing 40 is provided to allow the support leg of the bracket 11 to pass through, similarly to the missing portion of the housing 30 of the first body 3 .

The first body 3 and the second body 4 are separated in the length direction of the grip bar 10, and the mobile body 2 is held in a stable posture by gripping the grip bar 10 at two locations separated in the length direction. can be moved while keeping The connecting body 5 that connects the first body 3 and the second body 4 has a bellows shape as shown in FIG. Therefore, the moving body 2 including the first body 3 and the second body 4 can move with the deformation of the connecting body 5 even at the bent portion of the grip rod 10 . FIG. 4 is an explanatory diagram of a moving state at a curved portion of a handrail, and shows, for example, a moving state of the moving body 2 at a curved portion of the grip bar 10 at a transition from a hallway to stairs.

Four ultraviolet irradiators 42 fixed to the inner surface of the housing 40 face the grip rod 10 gripped by three driven wheels 41, and the ultraviolet rays emitted by each ultraviolet irradiator 42 are shown in the figure. The light spreads out as indicated by the two-dot chain line, and the entire upper surface and both side surfaces of the grip rod 10 are irradiated. The surface of the gripping rod 10 is effectively sterilized over substantially the entire movement range of the moving body 2 by ultraviolet irradiation inside the moving second body 4 .

The housing 40 surrounds the periphery of the ultraviolet ray irradiator 42 from the outside, and also functions as a light shielding member for shielding the gripping rod 10 from the ultraviolet ray. This can prevent ultraviolet rays harmful to the human body from leaking to the outside. Leakage of ultraviolet rays can be prevented more reliably by separately providing a light shielding member that covers the entire moving body 2 .

In FIG. 3, three driven wheels 41 and four ultraviolet irradiators 42 are shown side by side on the same cross section, but the ultraviolet ray irradiators 42 are preferably arranged on a different cross section from the driven wheels 41. desirable. As a result, it is possible to eliminate the overlap between the irradiation position of the ultraviolet rays and the rolling contact position of the driven wheel 41, so that the surface of the grip rod 10 can be irradiated with the ultraviolet rays satisfactorily.

Inside the housing 40, a rechargeable battery that serves as a power source for the ultraviolet irradiator 42 and the movement motor 33 described above may be arranged. Run times with movement and UV irradiation can be lengthened.

Furthermore, an imaging unit 44 is attached to the outside of the second body 3 as shown in FIGS. 1 and 3 . The imaging unit 44 is, for example, a camera whose imaging area is the opposite side of the side wall 12 to which the handrail 1 is fixed, as indicated by an arrow in FIG. image.

FIG. 5 is a block diagram showing the configuration of the control system of the sterilization device. The control unit 7 provided inside the first body 3 includes a CPU 70 , a ROM 71 and a RAM 72 , and controls the movement motor 33 and the ultraviolet irradiator 42 by the operation of the CPU 70 according to the control program stored in the ROM 71 .

A motor 33 and an ultraviolet irradiator 42 to be controlled are connected to the controller 7 via separate drive circuits. The control unit 7 is connected to the obstacle sensor 35 and the imaging unit 44 described above, and furthermore, a remaining amount detector 73 for detecting the remaining amount of charge of the rechargeable battery 6 and a transmission unit for transmitting to an external device. 74 are connected.

The control unit 7 starts operation in response to an appropriate activation operation, gives an operation command to the movement motor 33 and the ultraviolet irradiation device 42 , drives the movement motor 33 , and operates the ultraviolet irradiation device 42 . The activation operation may be an operation of an activation switch (not shown) provided on the mobile body 2 or an operation of an external device capable of communicating with the control unit 7 .

The moving body 2 is driven by the moving motor 33 to move along the gripping rod 10, and the ultraviolet ray irradiator 42 irradiates the surface of the gripping rod 10 with ultraviolet rays. Since the irradiation of ultraviolet rays is carried out continuously or intermittently according to the movement of the mobile body 2, for example, in public facilities such as hospitals and nursing care facilities, long-sized beams installed over corridors, stairs, and living rooms. The grip rod 10 of the handrail 1 can be effectively sterilized without manpower.

During the above operation, the control unit 7 sequentially takes in the output of the obstacle sensor 35, determines the presence or absence of an obstacle in front of the movement route, and when it is determined that there is an obstacle, the movement motor 33 and the ultraviolet irradiator 42 to stop the moving motor 33 and the ultraviolet ray irradiator 42 . The control unit 7 waits for a preset standby time to elapse, and when the obstacle is no longer detected after the elapse of the standby time, cancels the stoppage of the moving motor 33 and the ultraviolet ray irradiator 42, and continues to operate after the elapse of the standby time. If the obstacle detection continues, the control operation is terminated.

The obstacles are, for example, fingers of the user who grip the grip rod 10 . In this case, since the moving body 2 is stopped by the above-described operation of the control section 7, it is possible to avoid collision with the user. Further, since the operation of the ultraviolet irradiator 42 is also stopped, the influence of the ultraviolet rays on the user can be eliminated. The waiting time may be set to a time sufficient for the user to move (for example, several minutes). Operation can be resumed automatically.

The obstacle is, for example, a stopper provided at the end of the movement path. In this case, the moving body 2 and the ultraviolet irradiator 42 are stopped by the above-described operation of the control unit 7, and this state continues even after the waiting time has elapsed, so the operation of the sterilization device can be automatically stopped at the terminal position. can.

In addition, the control unit 7 sequentially takes in the output of the remaining amount detection unit 73 and monitors the remaining charge amount of the rechargeable battery 6. After moving to a predetermined stop position set in advance, a stop command is given to the moving motor 33 and the ultraviolet ray irradiator 42, and a control operation to stop the moving motor 33 and the ultraviolet ray irradiator 42 is performed.

The stop position is, for example, the position of a charging station provided in the middle of the movement route. In this case, contact or non-contact charging with the charging station can eliminate the shortage of remaining charge. In addition, the stop position is a position that facilitates recovery by the user. In this case, the shortage of the remaining charge can be eliminated by charging by the collector. The control unit 7 operates in response to the activation operation again, and restarts the operation of the sterilization device.

The imaging unit 44 operates in response to an operation command from the control unit 7, and captures an image (moving or still image) around the moving body 2 as described above. The control unit 7 captures the captured image of the imaging unit 44 and transmits it to the external device via the transmission unit 74 . The user can visually recognize the captured image transmitted to the external device and appropriately grasp the situation around the movement position of the mobile body 2 . For example, when a sterilization device is operated at night in public facilities such as hospitals and nursing homes, the captured image can be effectively used as security information for the facility. The imaging area of the imaging unit 44 is not limited to the area described above, and for example, an omnidirectional camera capable of imaging in all directions may be used as the imaging unit 44 . It is also possible to store the image captured by the imaging unit 44 in a detachable storage medium provided in the sterilization apparatus, remove the storage medium after the operation is finished, and reproduce the captured image to check the surrounding situation. be.

The transmission unit 74 also functions to transmit the movement position of the mobile body 2 . The mobile position can be transmitted as GPS signals, beacon signals, for example. The user can check the movement position of the mobile body 2 from the surrounding information sent to the external device at any time and monitor the operating status of the sterilization device. , inspection becomes possible.

In addition, the transmission unit 74 can transmit peripheral information other than the image around the mobile body 2 and the movement position of the mobile body 2 . For example, a human sensor that detects the presence or absence of people around the mobile body 2 may be provided, and the detection result of the human sensor may be transmitted as peripheral information. The detection result of the human sensor can be used as security information at night, like the captured image of the imaging unit 44 . Further, the detection result of the human sensor can be used for control of movement and stopping and resuming of ultraviolet irradiation, like the detection result of the obstacle sensor 35 .

The sterilization device configured as described above can be provided as a handrail 1 pre-equipped at an appropriate position of the continuous gripping rod 10 . It is also possible to retrofit to the existing handrail 1 . In the handrail 1 provided with the sterilization device, the surface of the grip rod 10 is desirably coated with a photocatalytic active substance such as titanium dioxide, that is, a so-called photocatalytic coating. The photocatalyst coating acts to enhance the sterilization effect of ultraviolet irradiation.
