The sterilization device according to the present embodiment includes a strap having a ring-shaped handle and a support member supporting the handle so that the handle is rotatable in the circumferential direction. A light-shielding cover that covers a portion of the handle in the circumferential direction so as to be rotatable in any direction, and a portion of the handle that is covered by the cover inside the cover is irradiated with ultraviolet rays. and a display unit for displaying an image is provided on the outer surface of the cover, and the image displayed on the display unit is switched depending on whether the handle is being held. It is characterized by

In this embodiment, the handle is supported by the supporting member and can rotate in the circumferential direction. A part of the handle in the circumferential direction is covered with a cover.
Alternatively, in this embodiment, the handle is supported by the support portion and can rotate in the circumferential direction. A portion of the handle in the circumferential direction is covered with a cover having a support portion. The cover is supported by the support member.

Inside the cover, the portion of the handle covered by the cover is irradiated with ultraviolet rays. The user holds the part of the handle that is not covered with the cover.
Ultraviolet rays (particularly, ultraviolet C waves having short wavelengths of 280 nm or less) can effectively kill all kinds of pathogenic bacteria and viruses in a short period of time. Therefore, the portion of the handle covered with the cover can be effectively sterilized.
Since sterilization is performed using the ultraviolet light emitted by the light emitting element, frequent maintenance is not required, and the sterilization effect can be maintained for a long period of time.

The user rotates the handle, for example, before grasping the handle. As the handle rotates, the part of the handle not covered with the cover moves inside the cover and is covered with the cover, and the part covered with the cover of the handle (that is, the disinfected part of the handle) ) moves to the outside of the cover and is exposed from the cover. Therefore, the user can grip the sterilized portion of the handle.
Since the cover has a light-shielding property, it is possible to suppress the leakage of ultraviolet rays to the outside of the cover.

In this embodiment, a support member (strap) is wrapped around the handle. A cover covers the upper portion of the handle and the lower end of the support member.
Alternatively, in the present embodiment, the handle (belt) is wrapped around the supporting portion (roller). The cover covers the upper part of the handle and is fixed to the lower end of the support member (strap).

The user grips the lower portion of the handle. The user's hand contacts the lower portion of the handle.
As the handle rotates, the upper part of the handle is exposed from the cover and becomes the lower part of the handle, and the lower part of the handle is covered with the cover and becomes the upper part of the handle. Since the light-emitting element irradiates ultraviolet rays toward the upper part of the handle, it is possible to effectively sterilize the part of the handle that comes into contact with the user's hand.

In this embodiment, the light emitting elements are turned on and off periodically. Since ultraviolet rays are not irradiated for a long time, deterioration of the handle due to ultraviolet rays can be suppressed.

In this embodiment, the light-emitting element is lit when the handle is rotated. That is, when the portion of the handle that is not covered with the cover is covered with the cover, disinfection of the handle can be started.
Since the light emitting element is extinguished when a predetermined time has elapsed after the light emitting element is turned on, there is no fear that the handle will be exposed to ultraviolet rays for a long time.

In this embodiment, the handle is driven by a motor and automatically rotates. Therefore, it is not necessary for the user to rotate the handle, so convenience for the user can be improved.
The light emitting element is lit when the handle is rotated a predetermined amount. That is, when a predetermined range of the portion of the handle that is not covered by the cover is covered with the cover, disinfection of the handle can be started.
Since the light emitting element is extinguished when a predetermined time has elapsed after the light emitting element is turned on, there is no fear that the handle will be exposed to ultraviolet rays for a long time.

In this embodiment, the sterilization status of the handle is notified. Therefore, the user can select and use a strap whose handle has been sterilized, for example.

In the present embodiment, an image showing, for example, the sterilization status of the handle is displayed on the display section provided on the outer surface of the cover. In this case, the user can select and use, for example, a strap whose handle has been sterilized.
Alternatively, the display unit displays, for example, an image for advertising a product or an entertainment. In this case, the strap can be used as digital signage.

In this embodiment, the bulletin board provided on the outer surface of the cover can be used to advertise products, entertainment, or the like.

In this embodiment, since the cover has a predetermined character shape, the design of the strap can be improved.

In this embodiment, the handle is supported by the supporting member and can rotate in the circumferential direction.
A part of the handle in the circumferential direction is covered with a cover.

Inside the cover, the portion of the handle covered by the cover is irradiated with ultraviolet rays. The user holds the part of the handle that is not covered with the cover.
Ultraviolet rays (particularly, ultraviolet C waves having short wavelengths of 280 nm or less) can effectively kill all kinds of pathogenic bacteria and viruses in a short period of time. Therefore, the portion of the handle covered with the cover can be effectively sterilized.
Since sterilization is performed using the ultraviolet light emitted by the light emitting element, frequent maintenance is not required, and the sterilization effect can be maintained for a long period of time.

The user rotates the handle, for example, before grasping the handle. As the handle rotates, the part of the handle not covered with the cover moves inside the cover and is covered with the cover, and the part covered with the cover of the handle (that is, the disinfected part of the handle) ) moves to the outside of the cover and is exposed from the cover. Therefore, the user can grip the sterilized portion of the handle.
Since the cover has a light-shielding property, it is possible to suppress the leakage of ultraviolet rays to the outside of the cover.

In this embodiment, the two cover members are integrated so as to sandwich the handle and the support member. As a result, the formation of the cover and the attachment of the cover to the support member can be achieved simultaneously and easily.

According to the strap and the sterilization device of the present embodiment, sterilization can be effectively carried out for a long period of time.

A vehicle passenger grasps the lower portion of the handle 11 to support his or her body.
In order to disinfect the handle 11, the strap 1 is provided with a disinfecting device 3.

FIG. 2 is a perspective view showing the sterilization device 3. FIG.
The sterilization device 3 has a cover 4 .
A cover 4 covers the upper half of the handle 11 and the lower end of the strap 12 . Even when covered with the cover 4, the handle 11 is rotatable in the circumferential direction.
The cover 4 has a hollow hemispherical shape that is flattened in the front-rear direction.

As shown in FIG. 1, two insertion holes 41, 41 are arranged side by side in the bottom wall of the cover 4 in the left-right direction. The handle 11 is inserted through the insertion holes 41, 41 with play.
A through hole 42 through which the strap 12 passes is provided at the top of the cover 4 . The peripheral edge of the through-hole 42 sandwiches the strap 12 from the front-rear direction. Since the lower end of the strap 12 is wrapped around the handle 11, the front and rear sides of the strap 12 are wider than the length of the through-hole 42 in the front-rear direction. Therefore, the lower end of the strap 12 does not pass through the through-hole 42 to the upper side of the cover 4 .

Two holding pieces 43 , 43 are provided on the inner surface of the cover 4 . The holding pieces 43 , 43 protrude downward from the periphery of the through hole 42 . One surfaces of each of the holding pieces 43, 43 face each other in the left-right direction.

The cover member 52 has the remaining half of the peripheral portion of each insertion hole 41, the remaining half of the peripheral portion of the through hole 42, and the remaining half of each holding piece 43 (the remaining half of the peripheral portion of the insertion hole 431).
Through holes 521, 521, . . . are provided in the cover member 52 so as to correspond to the screw holes 511, 511, .
The cover members 51 and 52 shown in FIGS. 1 and 3 are disposed so as to sandwich the handle 11 in a non-contact state from the front and rear direction and sandwich the strap 12 from the front and rear direction, and the cover member 52 is screwed to the cover member 51. By doing so, they are integrated as shown in FIG.

In the strap 1, the LEDs 31, 31 emit light, so that the upper half of the handle 11 inside the cover 4 is irradiated with ultraviolet rays. Ultraviolet rays (in particular, ultraviolet C waves) have the effect of acting on the DNA of living organisms to inactivate the DNA, and can effectively kill all kinds of pathogenic bacteria and viruses in a short period of time. Therefore, the portion of the handle 11 irradiated with ultraviolet rays can be effectively sterilized.
Since sterilization is performed using the ultraviolet rays emitted by the LEDs 31, 31, frequent maintenance of the sterilization device 3 is not required. That is, the sterilization effect can be maintained for a long period of time.

A user grips the lower portion of the handle 11 . The user's hand contacts the lower portion of handle 11 .

The LED driver 312 starts supplying power to the LEDs 31, 31 when a predetermined ON signal is input. As a result, the LEDs 31, 31 are lit. When the ON signal stops being input, the LED driver 312 stops supplying power to the LEDs 31 , 31 . As a result, the LEDs 31, 31 are turned off.

The driving circuit 331 turns on the red LED of the notification unit 33 and turns off the green LED when a control signal indicating red is input. When a control signal indicating green is input, the drive circuit 331 turns on the green LED of the notification unit 33 and turns off the red LED.
The control unit 321 has a CPU and executes predetermined processing according to a computer program.
The rotation detector 63 is provided on the rotation shaft of one roller 61 and detects whether or not the roller 61 has rotated. The detection result of the rotation detection section 63 is given to the control section 321 .

FIG. 10 is a flow chart showing the procedure of the sterilization process executed on the strap 1. As shown in FIG.
The control unit 321 determines whether the handle 11 has rotated based on the detection result of the rotation detection unit 63 (S11).
If the handle 11 is not rotated (NO in S11), the handle 11 executes the process of S11 again.

When the handle 11 rotates (YES in S11), the controller 321 starts outputting an ON signal to the LED driver 312 to light the LEDs 31, 31 (S12). Further, the control unit 321 starts outputting a control signal indicating red to the drive circuit 331, thereby causing the notification unit 33 to light up in red (S13). Furthermore, the control unit 321 starts counting the elapsed time (S14).
Next, the control unit 321 determines whether or not a predetermined time has passed (S15).

When the predetermined time has passed (YES in S15), the control unit 321 terminates the input of the ON signal to the LED driver 312, thereby extinguishing the LEDs 31, 31 (S16). Further, the control unit 321 causes the notification unit 33 to light green by starting to output a control signal indicating green to the drive circuit 331 (S17). Furthermore, the control unit 321 terminates the sterilization process.
After the sterilization process ends, the control unit 321 starts the sterilization process again from S11.

If the predetermined time has not elapsed (NO in S15), the control unit 321 determines whether the handle 11 has rotated based on the detection result of the rotation detection unit 63 (S18).
If the handle 11 is not rotated (NO in S18), the handle 11 returns the process to S15.
If the handle 11 has rotated (YES in S18), the handle 11 returns the process to S14.

By the way, for example, the amount of ultraviolet irradiation required to sterilize Escherichia coli with 254 nm ultraviolet rays with a killing rate of 99.9% is 5400 μW·sec/cm 2 . The amount of ultraviolet irradiation is said to be 3400 μW·sec/cm 2 . It is desirable that the predetermined length of time for which the ultraviolet rays continue to be irradiated is obtained from the intensity of the ultraviolet rays emitted from the LEDs 31 and 31 and the area to be sterilized.

The red notification portion 33 indicates that the handle 11 is being sterilized. The green notification portion 33 indicates that the handle 11 has been sterilized. That is, the notification unit 33 notifies the sterilization status of the handle 11 .
By rotating the handle 11 of the strap 1 with the notification part 33 of green color, the user can hold the part of the handle 11 that has been sterilized.

A display portion 46 may be provided on the outer surface of the cover 4 instead of the notification portion 33 . In this case, the control unit 321 causes the display unit 46 to display an image indicating that the handle 11 is being sterilized in the process of S13. Also, in the process of S17, the display unit 46 is caused to display an image indicating that the handle 11 has been sterilized.

According to the strap 1 as described above, the LEDs 31, 31 are lit when the handle 11 is rotated. That is, when the portion of the handle 11 that is not covered with the cover 4 is covered with the cover 4, the sterilization of the handle 11 can be started.
Since the LEDs 31, 31 are turned off when a predetermined time has passed after the LEDs 31, 31 are turned on, there is no risk that the handle 11 will be exposed to ultraviolet rays for a long time.

The side wall of the cover 4 may be provided with an inspection opening and a lid for the inspection opening. For example, when performing maintenance and inspection of the strap 1, the lid is opened and the inside of the cover 4 is inspected and maintained through the inspection opening.
The cover 4 is not limited to a rectangular box shape.
Also, the cover 4 is not limited to the configuration in which it is fixed to the lower end of the strap 12 . For example, the cover 4 may be fixed to the distal end of a lever, arm, or the like whose proximal end is attached to the holding pipe 21 .

Embodiment 4.
The strap 1 of this embodiment is substantially the same as the strap 1 of the third embodiment. The strap 1 of the present embodiment has substantially the same effects as the strap 1 of the third embodiment. In the following, the differences from the third embodiment will be explained, and the same components as those of the third embodiment will be denoted by the same reference numerals, and the explanation thereof will be omitted.

FIG. 11 is a cross-sectional view showing a strap 1 according to Embodiment 4. As shown in FIG.

A motor driver 651 for the motor 65 is provided in the control device 32 . A predetermined control signal is input to the motor driver 651 . The motor driver 651 drives the motor 65 based on the input control signal.

The strap 1 includes a grip detection section 66 instead of the rotation detection section 63 of the third embodiment.
The grip detection unit 66 detects whether or not the handle 11 is gripped. A detection result of the grip detection unit 66 is given to the control unit 321 .

The grip detection unit 66 is, for example, a microswitch arranged between the holding pipe 21 and the portion of the strap 12 that is wound around the holding pipe 21 .
Normally, the grip detector 66 is off. The strap 12 is pulled down by gripping the handle 11 . A pulled down strap 12 turns on the grip detector 66 . When the hand is released from the handle 11, the grip detector 66 pushes the strap 12 up to its original position and turns off. That is, when the grip detector 66 is on, the handle 11 is gripped, and when the grip detector 66 is off, the handle 11 is not gripped.
Note that the grip detector 66 is not limited to being arranged between the strap 12 and the holding pipe 21 . Also, the grip detection unit 66 is not limited to a microswitch.

FIG. 13 is a flow chart showing the procedure of the sterilization process executed on the strap 1. As shown in FIG.
The control unit 321 determines whether or not the rotated flag is set (S31). The rotated flag is set when the handle 11 rotates by a predetermined amount in the rotation process described later.
If the rotated flag has been reset (NO in S31), the control unit 321 executes the process of S31 again.
If the rotated flag is set (YES in S31), the controller 321 resets the rotated flag (S32) and lights the LEDs 31, 31 (S33).

Next, the control unit 321 starts counting the elapsed time (S34), and determines whether or not a predetermined time has passed (S35).
If the predetermined time has not elapsed (NO in S35), the control unit 321 executes the process of S35 again.
If the predetermined time has elapsed (YES in S35), the control unit 321 turns off the LEDs 31 (S36), sets the sterilization completed flag (S37), and terminates the sterilization process.
After the sterilization process ends, the control unit 321 starts the sterilization process again from S31.
A control unit 321 that executes the sterilization process shown in FIG. 13 functions as an element control unit in the embodiment.

14 and 15 are flowcharts showing the procedure of the rotation process executed by the strap 1. FIG.
As shown in FIG. 14, the control unit 321 determines whether or not the handle 11 is held (S51). The control unit 321 determines that the handle 11 is gripped when the grip detection unit 66 is switched from off to on.
If the handle 11 is not held (NO in S51), the control section 321 executes the process of S51 again.

When the handle 11 is gripped (YES in S51), the control unit 321 determines whether or not the hand is released from the handle 11 (S52). The control unit 321 determines that the hand has been released from the handle 11 when the grip detection unit 66 is switched from on to off.
If the handle 11 is still being held (NO in S52), the controller 321 executes the process of S52 again.

When the hand is released from the handle 11 (YES in S52), the control unit 321 lights the notification unit 33 in red (S53), and determines whether or not the sterilization completion flag is set (S54).
If the sterilization flag is set (YES in S54), the controller 321 resets the sterilization flag (S55).

Next, as shown in FIG. 15, the controller 321 rotates the handle 11 by outputting a control signal to the motor driver 651 (S71).
The control signal output in the process of S71 is for rotating the handle 11 by a predetermined amount. When the handle 11 rotates a predetermined amount (for example, 1/2 rotation), the non-sterilized portion of the handle 11 extends over the rollers 62, 62, . . .

After the processing of S71 ends, the control unit 321 determines whether or not the rotation of the handle 11 has ended (S72).
When the handle 11 has finished rotating (YES in S72), the control unit 321 sets a rotated flag (S73), lights the notification unit 33 in green (S74), and terminates the rotation process.
After completing the rotation process, the control unit 321 starts the rotation process again from S51.

By the way, there is a possibility that the handle 11 is held before the sterilization flag is set in S37 of FIG. 13, that is, before the sterilization is completed.
As shown in FIG. 14, when the sterilization completion flag is reset (NO in S54), the control unit 321 determines whether or not the handle 11 is gripped (S56).
If the handle 11 is not held (NO in S56), the control section 321 returns the process to S54.

When the handle 11 is held (YES in S56), the control unit 321 determines whether or not the hand has been released from the handle 11 (S57).
If the handle 11 is still being held (NO in S57), the controller 321 executes the process of S57 again.
When the hand is released from the handle 11 (YES in S57), the control section 321 returns the process to S54.

At S71 shown in FIG. 15, the handle 11 starts rotating. The handle 11 may be grasped before the rotation of the handle 11 is completed.
If the handle 11 is rotating (NO in S72), the controller 321 determines whether the handle 11 is gripped (S75).
If the handle 11 is not held (NO in S75), the control section 321 returns the process to S72.

When the handle 11 is gripped (YES in S75), the controller 321 stops the rotation of the handle 11 by stopping the rotation of the driving roller 64 via the motor driver 651 (S76).
Next, the control unit 321 sets a rotated flag (S77), and shifts the process to S57.
A control unit 321 that executes the rotation processing shown in FIG. 12 functions as the rotation control unit in the embodiment.

According to the strap 1 as described above, when the handle 11 is held and the hand is released from the handle 11, the notification part 33 turns red. A user who visually recognizes the red notification portion 33 can know that the lower portion of the handle 11 has not been sterilized.
Also, the handle 11 is driven by the motor 65 to automatically rotate. Therefore, since the user does not need to rotate the handle 11, convenience for the user can be improved.

The LEDs 31, 31 are turned on when the handle 11 is rotated by a predetermined amount. That is, when the handle 11 rotates and a predetermined range of the portion of the handle 11 not covered by the cover 4 is covered with the cover 4, disinfection of the handle 11 can be started.
Since the LEDs 31, 31 are turned off when a predetermined time has passed after the LEDs 31, 31 are turned on, there is no risk that the handle 11 will be exposed to ultraviolet rays for a long time.

The handle 11 is rotated by a predetermined amount when the sterilization of the upper portion of the handle 11 is completed and the handle 11 is not gripped. If the handle 11 is gripped while the handle 11 is rotating, the rotation of the handle 11 is stopped. Then, the upper portion of the handle 11 is sterilized when the rotation of the handle 11 is stopped.
When the handle 11 has finished rotating a predetermined amount, the notification part 33 turns green. A user who visually recognizes the green notification portion 33 can know that the lower portion of the handle 11 has been sterilized.
