In this embodiment, when the user grasps the handle, the user's hand comes into contact with the contact surface of the handle.
The contact surface of the handle is irradiated with ultraviolet light. Ultraviolet rays (particularly ultraviolet C waves having a short wavelength of 280 nm or less) can effectively kill all kinds of pathogenic bacteria and viruses in a short period of time. Therefore, the contact surface of the handle can be effectively sterilized.
Since sterilization is performed using ultraviolet light emitted by the light emitting elements, there is no need for frequent maintenance and the sterilization effect can be maintained over a long period of time.

In this embodiment, the contact surface is part of the surface of the light guide.
The ultraviolet light emitted from the light emitting element toward the other part of the surface of the light guide is guided to the contact surface through the inside of the light guide. Therefore, the contact surface can be irradiated with ultraviolet light through the light guide.

In this embodiment, the contact surface is the upper part of the circumferential surface of the light guide.
Since the optical axis of the light emitting element is directed toward the lower part of the circumferential surface of the light guide, the ultraviolet light emitted by the light emitting element enters the inside of the light guide from the lower part of the circumferential surface of the light guide and is guided to the contact surface. Therefore, even though the contact surface faces upward, ultraviolet rays can be irradiated upward.

In this embodiment, the contact surface is the peripheral surface of the grip body.
The optical axis of the light emitting element is directed toward one end of the grip, and the light emitting element is disposed at the other end of the grip. The contact surface is irradiated with ultraviolet light emitted by the light emitting element. Therefore, ultraviolet rays can be irradiated sideways.

In this embodiment, each of the plurality of light emitting elements arranged in parallel in the circumferential direction of the grip body emits ultraviolet light. Moreover, the ultraviolet rays are diffused by the unevenness provided on the peripheral surface of the gripping body. Therefore, the ultraviolet rays can be evenly distributed over the circumferential surface of the gripping body.

In this embodiment, the light-emitting element lights up when the handle is gripped, that is, when the contact surface of the light guide is covered by the user's hand, so the handle is held together with the handle. The hands you hold can also be sterilized.
Since the light emitting element is turned off after a predetermined period of time has elapsed after the light emitting element is turned on, there is no risk that the handle and the hand holding the handle will be exposed to ultraviolet rays for a long period of time.

In this embodiment, since the light emitting element lights up when the handle is not gripped, there is no risk that the hand gripping the handle will be exposed to ultraviolet rays.
Since the light emitting element is turned off after a predetermined period of time has passed after the light emitting element is turned on, there is no risk that the handle will be exposed to ultraviolet rays for a long period of time.

In this embodiment, the light emitting element lights up when there is no one around the handle, so there is no risk of people being exposed to ultraviolet rays.
Since the light emitting element is turned off after a predetermined period of time has passed after the light emitting element is turned on, there is no risk that the handle will be exposed to ultraviolet rays for a long period of time.

In this embodiment, since the light emitting element lights up according to a command given from outside the strap, the handle can be sterilized at a timing desired by the person giving the command.
Since the light emitting element is turned off after a predetermined period of time has passed after the light emitting element is turned on, there is no risk that the handle will be exposed to ultraviolet rays for a long period of time.

In this embodiment, when the handle is gripped, the switch is switched and the light emitting element is turned on, and when the gripped handle is released, the switch is switched and the light emitting element is turned off. Alternatively, when the gripped handle is released, the switch is switched and the light-emitting element is turned on, and when the handle is gripped, the switch is switched and the light-emitting element is turned off.
Therefore, the handle can be sterilized with a simple configuration.

In this embodiment, information indicating that the handle is being gripped or information indicating that the handle is not being gripped can be transmitted to the outside of the strap. Information indicating that the handle is being held and information indicating that the handle is not being held can be used, for example, to estimate the occupancy rate.

According to the strap and gripping member of this embodiment, the handle and the gripping portion can be effectively sterilized over a long period of time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on drawings showing embodiments thereof.

Embodiment 1.
FIG. 1 is a perspective view showing a strap according to a first embodiment.
In the figure, 1 is a strap, and the strap 1 includes a handle 2 and a strap 3 (support member).
The handle 2 has a polygonal ring shape. In this embodiment, the handle 2 has an isosceles trapezoidal annular shape in which the upper base 21 is short and the lower base is long.
The strap 3 is an endless band. The strap 3 is wrapped around the upper bottom part 21 of the handle 2 and the holding pipe 41.

The holding pipe 41 is provided inside a vehicle (for example, a train or a bus). The holding pipe 41 extends in the horizontal direction (hereinafter referred to as the left-right direction). The holding pipe 41 is supported by a support (not shown) that projects downward from the ceiling of the vehicle.
Strap 3 hangs from retaining pipe 41. The handle 2 is suspended with the upper base 21 facing upward and the lower base facing downward.
At the center of the strap 3 in the vertical direction, a part of the front side and a part of the rear side of the strap 3 are fastened to each other with a suitable fastener.

A gate-shaped member 42 is fixed to the upper part of the holding pipe 41. The gate-shaped member 42 straddles the portion of the strap 3 that is wrapped around the holding pipe 41 in the left-right direction. The gate-shaped member 42 prevents the strap 3 from shifting in the left-right direction.

The passenger of the vehicle grasps the bottom of the handle 2 to support his or her body.
In order to sterilize the handle 2, the strap 1 is irradiated with ultraviolet light (particularly preferably ultraviolet C waves).

FIG. 2 is a sectional view showing the strap 1.
The handle 2 includes an upper base 21, two legs 22, 22, a lower holding part 23, and a light guide 24.
The upper base portion 21, the leg portions 22, 22, and the lower holding portion 23 shown in FIGS. 1 and 2 each have a rod shape and have light blocking properties. The upper base part 21, the legs 22, 22, and the lower holding part 23 are integrally provided in a trapezoidal ring shape with the upper base part 21 as the upper base and the lower holding part 23 as the lower base. Legs 22, 22 extend diagonally downward from both ends of the upper base 21, and both ends of the lower holding part 23 are continuous with the lower ends of the legs 22, 22, respectively.

A space extending in the left-right direction is provided inside the lower holding part 23. An upward opening extending in the left-right direction is provided at the upper part of the circumferential surface of the lower holding part 23. The opening of the lower holding part 23 communicates with the internal space of the lower holding part 23.
A communication path communicating with the internal space of the lower holding part 23 is provided inside each of the leg parts 22 , 22 .
Inside the upper bottom portion 21, a communication path is provided that communicates with the communication path of each of the leg portions 22, 22. An upward opening is provided in the upper part of the circumferential surface of the upper base part 21. The opening of the upper base 21 communicates with the communication path of the upper base 21. The opening of the upper base 21 is hidden by the strap 3 being wrapped around the upper base 21.

The light guide 24 is made of, for example, quartz glass. The light guide 24 has a rod shape with a rectangular cross section. On one of the four circumferential surfaces of the light guide 24 (hereinafter referred to as the lower surface 241), a plurality of recesses 242, 242, . . . are arranged in parallel along the longitudinal direction of the light guide 24. Corners of the surface of the light guide 24 facing the lower surface 241 (hereinafter referred to as the upper surface 243) and the other two peripheral surfaces are chamfered into a convex shape.

Note that the portion of the light guide 24 other than the lower surface 241 may have any shape as long as it can be easily held by the user. For example, a plurality of recesses for placing the user's fingers may be arranged in parallel in the longitudinal direction of the light guide 24.
It is preferable that reflecting portions are provided on both longitudinal end surfaces of the light guide 24 to reflect light incident on the end surfaces of the light guide 24 from inside the light guide 24 to the inside of the light guide 24. .

Each of the LEDs 51, 51, . . . shown in FIG. 2 is a light emitting element that emits ultraviolet light. The LEDs 51, 51, . . . are arranged in parallel on one surface of the strip-shaped LED board 511 in the longitudinal direction of the LED board 511.

The LED board 511 is housed in the internal space of the lower holding part 23 so that the longitudinal direction of the LED board 511 faces left and right, and the LEDs 51, 51, . . . face upward. The light guide 24 is placed on the top surface of the LED board 511 so that the longitudinal direction of the light guide 24 faces left and right, and the LEDs 51 are inserted into each recess 242 on the bottom surface 241 of the light guide 24. . Therefore, the ultraviolet light emitted by the LED 51 passes through the inner surface of the recess 242 of the light guide 24 and enters the inside of the light guide 24 .

The lower part of the light guide 24 and both ends of the light guide 24 are accommodated in the internal space of the lower holding part 23 . The remainder of the light guide 24 projects upward from the lower holding part 23 through the opening in the lower holding part 23 .
The lower holding part 23 holds the light guide 24 so that the upper part of the circumferential surface of the light guide 24 (the upper surface 243 and approximately the upper half of each of the front and rear surfaces of the light guide 24) is exposed. In addition, the lower holding part 23 connects the LEDs 51, 51, ... to the light guide 24 so that the optical axis of each LED 51 faces the lower part of the circumferential surface of the light guide 24 (specifically, the bottom of the recess 242). Hold it on the bottom side. Therefore, ultraviolet rays are irradiated upward from the LED 51 to the light guide 24.

The light guide 24 constitutes the upper half of the lower base of the handle 2 , and the lower holding portion 23 constitutes the lower half of the lower base of the handle 2 . The user holds the light guide 24 and the lower holding part 23 together. The upper part of the circumferential surface of the light guide 24 is a contact surface that comes into contact with the user's hand.

Power supply lines 52, 52 are connected to the LED board 511. The power supply lines 52, 52 pass through the internal space of the lower holding part 23, the communication passages of the legs 22, 22, and the communication passages of the upper base part 21, and are drawn out from the opening of the upper base part 21.

The upper base part 21, the legs 22, 22, and the lower holding part 23 are composed of, for example, a first member in which the front half of each part is integrally formed, and a second member in which the rear half of each part is integrally formed. has been done. When assembling the handle 2, first, the LED board 511, the power supply lines 52, 52, and the light guide 24 are arranged on the first member. A second member is then attached to the first member.

A grip detection section 11 is disposed between the holding pipe 41 and the portion of the strap 3 that is wrapped around the holding pipe 41.
The grip detection section 11 is a microswitch. Normally, the grip detection section 11 is off. By grasping the handle 2, the strap 3 is pulled down. The pulled down strap 3 turns on the grip detection section 11. When the hand is removed from the handle 2, the grip detection section 11 pushes the strap 3 back to its original position and turns off. That is, when the grip detection section 11 is on, the handle 2 is being gripped, and when the grip detection section 11 is off, the handle 2 is not being gripped.

The control device 12 for the strap 1 is placed on the top surface of the gate-shaped member 42 .
FIG. 3 is a block diagram showing the configuration of the control system of the strap 1.
The control device 12 includes a control section 121 and an LED driver 122. The control unit 121 and the LED driver 122 are connected to each other via a signal line.
The control unit 121 includes a CPU and a storage unit. The CPU executes predetermined processing according to a computer program stored in the storage unit.
The control section 121 and the grip detection section 11 are connected to each other via a signal line. This signal line is arranged around the strap 3 and the portal member 42. A signal indicating whether the grip detection unit 11 is on/off (detection result of the grip detection unit 11) is input to the control unit 121 via a signal line.

The power supply lines 52, 52 drawn out from the handle 2 pass through the inside of the strap 3, are drawn out to the gate-shaped member 42, and are connected to the LED driver 122 of the control device 12.
The control unit 121 and the LED driver 122 are each supplied with power from a power source (not shown) provided in the vehicle. A power supply line from the power source to the control device 12 is arranged inside the holding pipe 41 or on the circumferential surface of the holding pipe 41.

The LED driver 122 starts supplying power to the LEDs 51, 51, . . . when a predetermined ON signal is input. As a result, the LEDs 51, 51, . . . are turned on. When the input of the ON signal is interrupted, the LED driver 122 ends the power supply to the LEDs 51, 51, . As a result, the LEDs 51, 51, . . . are turned off.

FIG. 4 is a flowchart showing the procedure of the sterilization process performed on the strap 1.
The control unit 121 determines whether the handle 2 is gripped (S11). The control unit 121 determines that the handle 2 is gripped when the grip detection unit 11 is switched from off to on.
If the handle 2 is not gripped (NO in S11), the control unit 121 executes the process in S11 again.
When the handle 2 is gripped (YES in S11), the control unit 121 starts inputting an on signal to the LED driver 122, thereby lighting up the LEDs 51, 51, . . . (S12).

The ultraviolet rays emitted by the LEDs 51, 51, . . . enter the inside of the light guide 24 from the inner surfaces of the recesses 242, 242, . That is, the contact surface of the handle 2 is irradiated with ultraviolet rays through the light guide 24. Ultraviolet light (particularly ultraviolet C waves) has the effect of acting on the DNA of living things to inactivate it, and can effectively kill all kinds of pathogenic bacteria and viruses in a short period of time. Therefore, the handle 2 can be effectively sterilized.

The handle 2 of the strap 1 is placed at a higher position than the eye level of a typical passenger. Since the ultraviolet rays are irradiated upward, even though the ultraviolet rays are irradiated while the strap 1 is in use, the ultraviolet rays can be prevented from directly entering the user's eyes.
Furthermore, since the contact surface is covered by the user's hand, it is possible to reliably prevent light leakage from the light guide 24 from directly entering the user's eyes. Further, the hand holding the handle 2 as well as the hand holding the handle 2 can be sterilized.
Note that the contact surface of the light guide 24 may be provided with fine irregularities for diffusing ultraviolet rays.

After lighting the LEDs 51, 51, . . . in the process of S12, the control unit 121 starts counting the elapsed time (S13).
Next, the control unit 121 determines whether a predetermined time has elapsed (S14).
For example, the amount of UV irradiation required to kill Escherichia coli with a killing rate of 99.9% is 5400 μW・sec/cm2, and the amount of UV irradiation required to kill influenza viruses with a killing rate of 99.9% is 3400 μW.・It is said to be sec/cm2. The predetermined length of time during which ultraviolet rays are continuously irradiated is determined from the intensity of the ultraviolet rays irradiated from the LED 51 and the area to be sterilized.

When the predetermined time has elapsed (YES in S14), the control unit 121 turns off the LEDs 51, 51, . . . by ending the input of the ON signal to the LED driver 122 (S15). Finally, the control unit 121 ends the sterilization process.
After the sterilization process is finished, the control unit 121 starts the sterilization process again from S11.

If YES in S14, sterilization of the handle 2 and the user's hands has been completed. After that, the LEDs 51, 51, . . . are turned off in the process of S15, so there is no risk that the handle 2 and the hand holding the handle 2 will be exposed to ultraviolet rays for a long time.
When the user releases the handle 2 after the sterilization of the handle 2 is completed, the next user can grasp the sterilized handle 2.

If the predetermined time has not elapsed (NO in S14), the control unit 121 determines whether or not the hand has left the handle 2 (S16). The control unit 121 determines that the hand has left the handle 2 when the grip detection unit 11 is switched from on to off.
If the handle 2 is still being held (NO in S16), the control unit 121 returns the process to S14. As a result, the ultraviolet rays continue to be irradiated until the handle 2 is completely sterilized.

When the hand is removed from the handle 2 (YES in S16), the control unit 121 moves the process to S15 and turns off the LEDs 51, 51, .
If YES in S16, the LEDs 51, 51, . . . are turned off before the sterilization of the handle 2 is completed. However, once the next user grasps the handle 2, sterilization of the handle 2 and the user's hands will begin, so there is no particular problem.
In addition, when the hand is removed from the handle 2, the ultraviolet rays may continue to be irradiated until a predetermined period of time has elapsed.

According to the above-described strap 1, sterilization is performed using the ultraviolet light emitted by the LEDs 51, 51, . . . , so there is no need for frequent maintenance of the strap 1. That is, the sterilizing effect can be maintained over a long period of time.
Further, since the user does not have to actively sterilize the handle 2, it is highly convenient for the user.
A typical LED 51 emits visible light as well as ultraviolet light. Therefore, when the LED 51 is emitting light, the light guide 24 appears to be shining. When the light guide 24 is shining, passengers can see that the handle 2 is being sterilized.

Note that the grip detection section 11 is not limited to the configuration arranged between the strap 3 and the holding pipe 41. For example, the grip detection section 11 may be incorporated into the handle 2. The grip detection section 11 is not limited to a microswitch. For example, the grip detection section 11 may be a pressure sensor, an optical sensor, an electrostatic sensor, or a strain gauge.

A display panel may be provided on the outer surface of the strap 3. For example, an image showing the sterilization status of the handle 2 or an advertisement is displayed on the display panel.
The strap 1 may be equipped with a power source. The power source for the strap 1 is, for example, a dry cell or rechargeable battery built into the control device 12, or a solar cell provided on the outer surface of the strap 3.
The handle 2 is not limited to being supported by the strap 3. For example, the handle 2 may be supported by the distal end of a lever or arm whose base end is attached to the holding pipe 41.

Next, embodiments 2 to 6 will be explained. The straps 1 of the second to sixth embodiments are substantially the same as the straps 1 of the first embodiment. The straps 1 of the second to sixth embodiments have substantially the same effects as the straps 1 of the first embodiment. Below, differences from Embodiment 1 will be explained, and other components that are the same as Embodiment 1 will be given the same reference numerals and their explanation will be omitted.

Embodiment 2.
FIG. 5 is a block diagram showing the configuration of a control system of the strap 1 according to the second embodiment.
The strap 1 includes a switch 13 instead of the grip detection section 11 of the first embodiment.
In this embodiment, a switch 13 is interposed between a power source 43 and an LED driver 122 provided in the vehicle. When the switch 13 is on, power is supplied from the power source 43 to the LEDs 51, 51, . When the switch 13 is switched from on to off, the power supply from the power supply 43 to the LEDs 51, 51, . . . is cut off.

Switch 13 is a microswitch. The switch 13 is disposed between the holding pipe 41 and the portion of the strap 3 that is wrapped around the holding pipe 41, similarly to the grip detection section 11 of the first embodiment. The switch 13 is switched from off to on when the handle 2 is gripped, and switched from on to off when the user's hand is removed from the handle 2.
Therefore, when the handle 2 is gripped, the LEDs 51, 51, . . . light up, and the handle 2 and the user's hands are sterilized. When the hand is removed from the handle 2, the LEDs 51, 51, . . . are turned off.
According to the strap 1 as described above, the control section 121 of Embodiment 1 is unnecessary, so the configuration of the strap 1 is simple.

Note that the switch 13 may be switched from on to off when the handle 2 is gripped, and may be switched from off to on when the user's hand is removed from the handle 2. In this case, since sterilization is performed when the handle 2 is not being held, there is no risk that the hand holding the handle 2 will be exposed to ultraviolet rays.

Embodiment 3.
FIG. 6 is a block diagram showing the configuration of the control system of the strap 1 according to the third embodiment.
The strap 1 of this embodiment further includes a presence/absence detection section 14.
The presence/absence detection unit 14 detects the presence or absence of a passenger around the strap 1. The presence/absence detection unit 14 is, for example, a capacitance type proximity sensor. When there is a standing passenger directly below and around the strap 1, the presence/absence detection unit 14 is on. When there is no passenger standing directly below and around the strap 1, the presence/absence detection section 14 is off.
The detection result of the presence/absence detection unit 14 is input to the control unit 121.

FIG. 7 is a flowchart showing the procedure of the sterilization process performed on the strap 1.
The process of S11 shown in FIG. 7 is similar to the process of S11 shown in FIG. 4 (see Embodiment 1). When the handle 2 is gripped (YES in S11), the control unit 121 executes the processes from S12 shown in FIG. 4.
If the handle 2 is not gripped (NO in S11), the control unit 121 determines whether a passenger is present by determining whether the detection result of the presence/absence detection unit 14 is on. (S21). If there are passengers around the strap 1 (YES in S21), the control unit 121 returns the process to S11.

If there are no passengers around the strap 1 (NO in S21), the control unit 121 moves the process to S22. The processing from S22 to S25 is similar to the processing from S12 to S15 shown in FIG.
Since the LEDs 51, 51, . . . are turned on in the process of S22, the handle 2 can be sterilized when there are no passengers around the strap 1. Therefore, the next user can hold the sterilized handle 2.

If the predetermined time has not elapsed (NO in S24), the control unit 121 determines again whether a passenger is present (S26).
If there are no passengers around the strap 1 (NO in S26), the control unit 121 returns the process to S24. As a result, the ultraviolet rays continue to be irradiated until the handle 2 is completely sterilized.

If there are passengers around the strap 1 (YES in S26), the control unit 121 moves the process to S25 and turns off the LEDs 51, 51, .
The control unit 121 that executes the processes of S22 and S25 functions as an element control unit in the embodiment.

When there is no passenger around the strap 1, the intensity of the ultraviolet light emitted by the LEDs 51, 51, . . . may be higher than when the handle 2 is gripped. In this case, the predetermined time in S24 is shorter than the predetermined time in S14. That is, it is possible to complete sterilization in a short time.

The presence/absence detection unit 14 is not limited to a proximity sensor, and may be a camera, for example. In this case, the image captured by the camera and the image captured when no passenger is present around the strap 1 are compared. If the difference between the two is large (small), there are passengers around the strap 1 (there are no passengers).
A plurality of straps 1, 1, . . . are suspended from the holding pipe 41. The presence/absence detection section 14 may be common to the plurality of straps 1, 1, . . . . In this case, the presence/absence detection unit 14 detects the presence or absence of a passenger around the straps 1, 1, .

Embodiment 4.
FIG. 8 is a block diagram showing the configuration of the control system of the strap 1 according to the fourth embodiment.
The control device 12 further includes a communication section 123 and a clock 124.
The control unit 121 communicates with an information processing device 44 provided in the vehicle via the communication unit 123. A communication line from the information processing device 44 to the control device 12 is arranged inside the holding pipe 41 or on the circumferential surface of the holding pipe 41. The information processing device 44 includes an information storage section 441.
Clock 124 measures the current time.

The storage section of the control section 121 is provided with identification information for identifying the strap 1.
When the control unit 121 determines that the handle 2 is gripped (YES in S11 shown in FIG. 4), the control unit 121 outputs grip information indicating that the handle 2 is being gripped, identification information, and time information indicating the current time. is transmitted to the information processing device 44 via the communication unit 123. Further, when the control unit 121 determines that the hand has left the handle 2 (YES in S16 shown in FIG. 4), the control unit 121 outputs non-grip information indicating that the handle 2 is not gripped, identification information, and the current time. time information indicating the time is transmitted to the information processing device 44 via the communication unit 123. The control unit 121 as described above functions as a transmitting unit in the embodiment.
The information processing device 44 stores a set of the received grasping information or non-gripping information, identification information, and time information in the information storage unit 441.

The vehicle is equipped with a plurality of straps 1, 1, . . . By using the various information stored in the information storage section 441, it is possible to know whether a particular strap 1 was being used at any given time. When the strap 1 is in use, it is considered that the seats near the strap 1 are generally full. Therefore, using the various information stored in the information storage unit 441, it is possible to estimate the occupancy rate at any given time, for example.
The calculation for estimating the occupancy rate may be performed by the information processing device 44.
The information processing device 44 may transmit various information stored in the information storage unit 441 and vehicle identification information for identifying the vehicle to an information processing device outside the vehicle.

The operation unit 45 is provided, for example, in the driver's seat of the vehicle. The driver operates the operating unit 45, for example, while the vehicle is being transferred or when the vehicle is in the garage.
Information as to whether or not the operation unit 45 has been operated is provided to the information processing device 44 . When the operation unit 45 is operated, the information processing device 44 transmits a sterilization command to the control units 121, 121, . . . of the straps 1, 1, . . . to turn on the LEDs 51, 51, .
The control unit 121 receives the sterilization command via the communication unit 123. That is, the control unit 121 functions as a reception unit in the embodiment. When receiving the sterilization command, the control unit 121 turns on the LEDs 51, 51, . . . . The control unit 121 turns off the LEDs 51, 51, . . . after a predetermined period of time has elapsed. That is, the control unit 121 functions as a lighting/extinguishing control unit in the embodiment. Therefore, there is no risk that the handle 2 will be exposed to ultraviolet rays for a long time.

According to the strap 1 as described above, the handle 2 can be sterilized not only when the handle 2 is gripped, but also at any timing desired by the driver.
Note that the mobile terminal may function as a remote controller for the strap 1 by installing a predetermined application on the mobile terminal owned by the user.

Embodiment 5.
FIG. 9 is a perspective view showing the strap 1 according to the fifth embodiment.
FIG. 10 is a sectional view showing the strap 1.
The handle 2 of this embodiment has a rectangular ring shape. The handle 2 includes an upper side part 25, two side parts 26, 26, and a grip body 27.

The upper side portion 25 and the side portions 26, 26 are rod-shaped and have light blocking properties. The upper side portion 25 and the side portions 26, 26 are integrally provided so that the side portions 26, 26 extend downward from both ends of the upper side portion 25.
An insertion hole 251 that penetrates the upper side 25 in the front-rear direction is provided at the lower part of the upper side 25 . The strap 3 passes through the insertion hole 251 and is wrapped around the upper side 25.

The upper side portion 25 is provided with an opening and a communicating path similar to the opening and communicating path provided in the upper bottom portion 21 of the first embodiment. The opening of the upper side portion 25 is hidden by the strap 3.
A rectangular holding hole that opens to the right is provided at the lower end of the left side 26. Similarly, the lower end of the right side portion 26 is provided with a holding hole that opens to the left. Each side portion 26 is provided with a communication path that communicates with the holding hole of the side portion 26 and the communication path of the upper side portion 25 .

FIG. 11 is another sectional view showing the strap 1.
As shown in FIGS. 9 to 11, the grip body 27 has a rod shape with a circular cross section. A large number of projections and depressions 271 are provided on the peripheral surface of the gripping body 27 to diffuse ultraviolet rays. The unevenness 271 is so fine that at least the user holding the gripping body 27 does not feel uncomfortable. In FIG. 11, the unevenness 271 is highlighted. Although the unevenness 271 shown in FIG. 11 is provided regularly, it may be provided irregularly.

As shown in FIGS. 10 and 11, the LEDs 51, 51, . . . are arranged in parallel on one surface of a rectangular LED board 511. The LEDs 51, 51, . . . are equally spaced along a virtual circle that is slightly larger than the diameter of the gripping body 27. In this embodiment, the strap 1 includes two LED boards 511, 511.
The LED board 511 is accommodated in the holding hole of each side part 26 with both sides of the LED board 511 facing left and right and the LEDs 51, 51, ... facing the opening of the holding hole of the side part 26. .

The longitudinal direction of the grip body 27 is oriented in the left-right direction. Both ends of the grip body 27 are inserted into holding holes in the side parts 26, 26, respectively. Both end surfaces of the grip body 27 are separated from the LEDs 51, 51, . . . by an appropriate length in the left-right direction. A light-transmitting holder 272 is disposed between the inner circumferential surface of the holding hole of the side portion 26 and the circumferential surface of the end portion of the grip body 27 . The holder 272 prevents the grip body 27 from wobbling.
A passenger of the vehicle grips the grip body 27 to support his or her body. The peripheral surface of the grip body 27 is a contact surface that comes into contact with the user's hand.

The optical axis of each LED 51 arranged on the left side portion 26 faces to the right along the longitudinal direction of the grip body 27. Similarly, the optical axis of each LED 51 arranged on the right side portion 26 faces to the left. Since the ultraviolet light emitted by the LED 51 is diffused around the optical axis, the contact surface of the grip body 27 is irradiated with the ultraviolet light emitted by the LED 51.
The LEDs 51, 51, . . . are arranged in parallel in the circumferential direction of the grip body 27. Moreover, the ultraviolet rays are diffused by the unevenness 271 provided on the peripheral surface of the gripping body 27. Therefore, the ultraviolet rays can be evenly distributed over the circumferential surface of the gripping body 27.

A power supply line 52 is connected to the LED board 511. The power supply line 52 passes through the communication path of the side portion 26 and the communication path of the top side portion 25 and is drawn out from the opening of the top side portion 25 .

The upper side part 25 and the side parts 26, 26 are composed of, for example, a third member in which the front half of each part is integrally formed, and a fourth member in which the rear half of each part is integrally formed. When assembling the handle 2, first, the LED boards 511, 511, the power supply lines 52, 52, the grip body 27, and the holders 272, 272 are arranged on the third member. Next, a fourth member is attached to the third member.

A block diagram showing the configuration of the control system of the strap 1 is substantially the same as the block diagram shown in FIG. 3. However, different LED boards 511 are connected to the power supply lines 52, 52, respectively.

FIG. 12 is a flowchart showing the procedure of the sterilization process performed on the strap 1.
The process of S11 shown in FIG. 12 is similar to the process of S11 shown in FIG. If the handle 2 is not gripped (NO in S11), the control unit 121 executes the process in S11 again.
Note that the strap 1 may further include the presence/absence detection section 14 of the third embodiment. In this case, when the answer is NO in S11, the processes after S21 shown in FIG. 7 are executed.

When the handle 2 is gripped (YES in S11), the control unit 121 determines whether or not the hand is released from the handle 2 (S31). The process at S31 is similar to the process at S16 shown in FIG.
If the handle 2 is still being held (NO in S31), the control unit 121 repeats the process in S31.

When the hand is removed from the handle 2 (YES in S31), the control unit 121 moves the process to S32. The processing from S32 to S35 is similar to the processing from S12 to S15 shown in FIG.
Since the LEDs 51, 51, . . . are turned on in the process of S32, the handle 2 can be sterilized when the hand is released from the handle 2 that was being held. Therefore, there is no risk that the hand holding the handle 2 will be exposed to ultraviolet rays.
Since both ends of the grip 27 are shielded from light by the side parts 26, 26, even if the passenger looks into the grip 27 from left and right, there is no possibility that ultraviolet rays will directly enter the passenger's eyes.

If the predetermined time has not elapsed (NO in S34), the control unit 121 determines again whether the handle 2 is gripped (S36).
If the handle 2 is not gripped yet (NO in S36), the control unit 121 returns the process to S34. As a result, the ultraviolet rays continue to be irradiated until the handle 2 is completely sterilized.
When the hand is removed from the handle 2 (YES in S36), the control unit 121 turns off the LEDs 51, 51, . . . (S37). The process in S37 is similar to the process in S15 shown in FIG.
After completing the process in S37, the control unit 121 returns the process to S31.
Since the LEDs 51, 51, . . . are turned off in the process of S37, there is no possibility that the user's hands will be irradiated with ultraviolet rays even if the handle 2 is held during sterilization.

According to the above-described strap 1, since the user's hands are not irradiated with ultraviolet rays, it is possible to complete sterilization in a short time using high-intensity ultraviolet rays.

Note that the LEDs 51, 51, . . . may be arranged on the right side (and left side) of the left side (and right side) holder 272. In this case, the holder 272 does not need to be translucent.

The grip body 27 may have light guiding properties. In this case, the grip 27 is made of quartz glass, for example. Each LED 51 is arranged on the left or right side of the grip 27 with the optical axis of the LED 51 facing the end surface of the grip 27. The ultraviolet rays irradiated from the LED 51 toward the end surface of the grip 27 pass through the inside of the grip 27 and are guided to the contact surface. Therefore, the contact surface can be irradiated with ultraviolet light through the grip 27. When the contact surface is irradiated with ultraviolet rays through the grip 27, the LED 51 may be turned on when the grip 27 is gripped, as in the first embodiment.

The grip 27 may be configured as a grip such as a handrail or a door handle. When the grip 27 constitutes a handrail, a cap covering the end of the handrail or a joint between two handrails may hold the LED board 511. The grip detection unit 11 is, for example, a load sensor built into a bracket for attaching a handrail to a wall. When the handrail is gripped, a load is applied to the bracket, so the control unit 121 determines that the handrail is gripped when the detection result of the load sensor is larger than a predetermined threshold.

In the strap 1 of the first embodiment, the sterilization process shown in FIG. 12 may be performed.

Embodiment 6.
FIG. 13 is a perspective view showing a strap 1 according to a sixth embodiment.
FIG. 14 is a sectional view showing the strap 1.
The handle 2 of this embodiment has an isosceles trapezoidal annular shape in which the upper base 21 is short and the lower base 28 is long. The upper base 21, legs 22, 22, and lower base 28 of the handle 2 are integrally provided.
The lower bottom portion 28 has a rod shape with a circular cross section. A vehicle passenger grasps the lower sole 28 to support his or her body. The peripheral surface of the lower bottom portion 28 is a contact surface that comes into contact with the user's hand.
A first holding member 53 and a second holding member 54 are attached to the handle 2 .

The first holding member 53 has a short and small cylindrical shape. The peripheral wall of the first holding member 53 has an appropriate thickness. The first holding member 53 includes two semi-cylindrical members 531, 531 fixed to each other.
The inner diameter of the first holding member 53 corresponds to the outer diameter of the lower bottom portion 28 . On one end surface of the first holding member 53, a plurality of LEDs 51, 51, . . . are equally distributed in the circumferential direction of the first holding member 53. Further, a light emitting element 55 is arranged between any two of the LEDs 51, 51, . The light emitting element 55 emits infrared rays.
Power is supplied to the LEDs 51, 51, . . . through a power supply line 52. Power is supplied to the light emitting element 55 through a power supply line 56.

The second holding member 54 has substantially the same configuration as the first holding member 53. However, a light receiving element 57 is arranged instead of the light emitting element 55. The light-receiving element 57 continues to output a light-receiving signal through a signal line 58 (see FIG. 15 described later) while receiving the infrared light emitted by the light-emitting element 55.

The first holding member 53 and the second holding member 54 are attached to both ends of the lower bottom portion 28 such that the light emitting element 55 and the light receiving element 57 face each other. For example, the first holding member 53 is attached to the lower base 28 by fixing the semi-cylindrical members 531, 531 to each other so as to surround half the circumference of the lower base 28.

The optical axis of each LED 51 arranged on the first holding member 53 is directed toward the second holding member 54 along the longitudinal direction of the lower bottom portion 28 . Similarly, the optical axis of each LED 51 arranged on the second holding member 54 faces toward the first holding member 53. Since the ultraviolet light emitted by the LED 51 is diffused around the optical axis, the contact surface of the lower base 28 is irradiated with the ultraviolet light emitted by the LED 51.
The light emitting element 55 emits infrared rays toward the light receiving element 57. When the lower base 28 is gripped, the user's hands block infrared rays.

Power supply lines 52 and 56 are drawn out from the first holding member 53. The power supply lines 52 and 56 are arranged around the inner periphery of the handle 2, passed through the inside of the strap 3, drawn out to the portal member 42, and connected to the control device 12.
A power supply line 52 and a signal line 58 are drawn out from the second holding member 54 . The power supply line 52 and the signal line 58 are arranged on the inner periphery of the handle 2, passed through the inside of the strap 3, drawn out to the portal member 42, and connected to the control device 12.

FIG. 15 is a block diagram showing the configuration of the control system of the strap 1.
The control device 12 includes a control section 121, an LED driver 122, a light emitting circuit 125, and a light receiving circuit 126. The control unit 121, the LED driver 122, the light emitting circuit 125, and the light receiving circuit 126 are connected to each other via signal lines. The control unit 121, the LED driver 122, the light emitting circuit 125, and the light receiving circuit 126 are each supplied with power from a power source (not shown) provided in the vehicle.

The control unit 121 continues to input the ON signal to the light emitting circuit 125. A power supply line 56 is connected to the light emitting circuit 125 . The light emitting circuit 125 continues to supply power to the light emitting element 55 while the ON signal is input.
The light receiving circuit 126 inputs the light receiving signal input from the light receiving element 57 to the control unit 121. When the light reception signal is input from the light reception circuit 126 to the control unit 121, the handle 2 is not being gripped. When the light reception signal is not input to the control unit 121 from the light reception circuit 126, the handle 2 is being held.

The procedure of the sterilization process performed on the strap 1 is similar to the procedure of the sterilization process shown in FIG. However, the control unit 121 determines that the handle 2 is gripped when the input of the light reception signal from the light reception circuit 126 is interrupted. Further, the control unit 121 determines that the hand has been released from the handle 2 when the input of the light reception signal from the light reception circuit 126 is restarted.

According to the strap 1 as described above, the first holding member 53 and the second holding member 54 are attached to the handle of a known strap, the control device 12 is attached to the gate-shaped member 42, and the power supply lines 52, 52 are attached. , 56 and the signal line 58, the strap 1 can be configured.

Note that the first holding member 53 and the second holding member 54 may be attached to a grip such as a handrail or a door handle. When attached to a handrail, each of the first holding member 53 and the second holding member 54 may be configured as a cap covering the end of the handrail or a joint of two handrails.

A light emitting sheet that emits ultraviolet light may cover the surface of the handle or the surface of the grip. The user holds the light-emitting sheet by the handle or the grip part. The light-emitting surface of the light-emitting sheet is sterilized by ultraviolet light. In order to prevent ultraviolet rays from being irradiated in unnecessary directions, a part of the light emitting surface may be covered with a light shielding member. For example, by interposing a sheet-like pressure-sensitive sensor between the light-emitting sheet and the handle or gripping portion, it is possible to detect whether or not the light-emitting sheet is being gripped.

Embodiment 7.
FIG. 16 is a perspective view showing a gripping member according to Embodiment 7.
In the figure, 6 is a gripping member, and the gripping member 6 includes a handrail 7 (grip portion).
The handrail 7 includes a light guide 71 and a lower holding part 72.

The light guide 71 has a rod shape with a semicircular cross section. The light guide 71 is used with a planar peripheral surface (hereinafter referred to as a lower peripheral surface 711) facing downward and a curved peripheral surface (hereinafter referred to as an upper peripheral surface 712) facing upward. A plurality of recesses 713, 713, . . . are arranged in parallel on the lower peripheral surface 711 along the longitudinal direction of the light guide 71.

The lower holding portion 72 has a rod shape with a semicircular cross section. The lower holding portion 72 is used with its curved peripheral surface facing downward. A groove 721 extending over the entire length of the lower holding part 72 is provided on the planar peripheral surface of the lower holding part 72 . Groove 721 is open upward.
The LED board 511 is placed at the bottom of the groove 721 with the LEDs 51, 51, . . . facing upward.
The grip detection unit 11 is a sheet-like pressure-sensitive sensor, and is placed on the upper surface of the LED board 511.

The light guide 71 is held at the lower side so that the lower circumferential surface 711 faces the upper surface of the LED board 511 via the grip detection section 11 and the LEDs 51 are inserted into each recess 713 of the lower circumferential surface 711. It is fitted into the groove 721 of the portion 72. The upper circumferential surface 712 of the light guide 71 protrudes upward from the opening of the groove 721 except for both ends in the circumferential direction.
A bracket 61 for attaching the handrail 7 to a wall is attached to the end of the handrail 7. The control device 12 is incorporated inside the bracket 61.

The user grasps the handrail 7. The upper peripheral surface 712 of the light guide 71 is a contact surface that comes into contact with the user's hand. When the handrail 7 is gripped, a downward load is applied to the light guide 71. The grip detection unit 11 detects the load applied to the light guide 71. If the detection result of the grip detection unit 11 is greater than or equal to a predetermined threshold, the handrail 7 is being gripped. If the detection result of the grip detection unit 11 is less than the predetermined threshold, the handrail 7 is not gripped.

A block diagram showing the configuration of the control system of the gripping member 6 is substantially the same as the block diagram shown in FIG. 3.
The procedure of the sterilization process performed by the gripping member 6 is the same as the procedure of the sterilization process shown in FIG. 4 or FIG. 12. However, the control unit 121 determines that the handrail 7 is gripped when the detection result of the grip detection unit 11 exceeds a predetermined threshold. Further, the control unit 121 determines that the hand has left the handrail 7 when the detection result of the grip detection unit 11 is less than a predetermined threshold.

The ultraviolet rays emitted by the LEDs 51, 51, . . . enter into the light guide 71 from the inner surfaces of the recesses 713, 713, . That is, since the contact surface of the handrail 7 is irradiated with ultraviolet rays through the light guide 71, the handrail 7 can be effectively sterilized.
After the predetermined time has elapsed, the LEDs 51, 51, . . . are turned off, so there is no risk that the handrail 7 will be exposed to ultraviolet rays for a long time.

According to the gripping member 6 as described above, sterilization is performed using the ultraviolet light emitted by the LEDs 51, 51, . . . , so there is no need for frequent maintenance of the gripping member 6. That is, the sterilizing effect can be maintained over a long period of time.
Furthermore, since there is no need for the user to actively sterilize the handrail 7, it is highly convenient for the user.
A typical LED 51 emits visible light as well as ultraviolet light. Therefore, when the LED 51 is emitting light, the light guide 71 appears to be shining. When the light guide 71 is shining, passengers can see that the handrail 7 is being sterilized.

Note that the upper circumferential surface 712 of the light guide 71 may be provided with fine irregularities for diffusing ultraviolet rays.
A configuration similar to that of the handrail 7 of the gripping member 6 may be applied to a door handle, for example.

The embodiments disclosed herein are illustrative in all respects and should not be considered restrictive. The scope of the present invention is not intended to have the above-mentioned meaning, but is intended to include meanings equivalent to the scope of the claims and all changes within the scope of the claims.
The constituent elements (technical features) disclosed in each embodiment can be combined with each other, and new technical features can be formed by the combination.
