The headlight 100 is an illumination device that is attached to the user's head or helmet and emits light forward.
The headlight 100 includes a headband 10 and a headlight body 20 .
The headband 10 is configured in a ring shape, and the headlight 100 is attached to the user's head or helmet. The headband 10 is made of a stretchable material such as rubber so that it can fit closely to the user's head, etc. The circumference of the headband 10 can be adjusted to fit the size of the user's head, etc.

The headlight body 20 includes a band attachment member 30 and a body case member 40.
The headband 10 is attached to the band attachment member 30. The band attachment member 30 includes a substantially plate-shaped attachment body 31 and an angle adjustment portion 34 formed to protrude from the attachment body 31 toward the front side.

As shown in FIGS. 2A to 2D, the attachment main body 31 has attachment parts 32a and 32b on both left and right ends for attaching the headband 10, and an upper attachment part 33 for attaching the headband (not shown) at the upper end.
The angle adjustment part 34 is formed in an annular shape so that it can surround the main body case member 40 from the front, upper, and lower sides. The angle at which light is irradiated can be adjusted by rotating the main body case member 40 along the annular ring of the angle adjustment section 34.

The main body case member 40 has a substantially cylindrical shape that is long in the left-right direction as a whole, and both left and right ends are formed in a substantially hemispherical shape. The main body case member 40 can accommodate a battery as a power source for emitting light, and is composed of various parts for emitting light.
Specifically, the main body case member 40 includes a main light emitting section 41, an auxiliary light emitting section 42, an operation section 43, a lid section 44, a battery case section 45, a socket section 53, and a link section 66 ( (See Figures 2A to 2E).

The main light emitter 41 emits light forward by emitting light. The main light emitter 41 emits light when power is supplied from a battery housed in the battery case 45. The main light emitter 41 emits light with a longer irradiation distance than the auxiliary light emitter 42. The main light emitter 41 is located on the front side of the main body case member 40, biased toward the right side. An LED (light emitting diode) is used for the main light emitter 41 in this embodiment. The main light emitter 41 in this embodiment emits white light (first color). The configuration and color of light of the main light emitter 41 can be changed as appropriate depending on the specifications of the headlight 100.

The auxiliary light emitting section 42 emits light toward the front by emitting light. The auxiliary light emitting section 42 emits light when power is supplied from a battery housed in the battery case section 45 . The auxiliary light emitting section 42 emits light with a shorter irradiation distance than the main light emitting section 41. Further, the auxiliary light emitting section 42 is located on the front surface of the main body case member 40, and is located closer to the center in the left-right direction than the main light emitting section 41. An LED (light emitting diode) is used for the auxiliary light emitting section 42 of this embodiment. Further, the auxiliary light emitting section 42 of this embodiment emits red light (second color). Note that the configuration of the auxiliary light emitting section 42 and the color of the light can be changed as appropriate depending on the specifications of the headlight 100.

The operation unit 43 is a button that can be operated by the user. The operating section 43 is located on the upper surface of the main body case member 40 and is biased toward the right side.
The operation section 43 of this embodiment has a light emitting state in which either the main light emitting section 41 or the auxiliary light emitting section 42 emits light whenever the user presses the button for a long time, and a light emitting state in which either the main light emitting section 41 or the auxiliary light emitting section 42 emits light. The light goes out.The light goes out.
Further, the operation unit 43 of the present embodiment can change the light emitting state each time the user presses it once in a light emitting state in which either the main light emitting unit 41 or the auxiliary light emitting unit 42 emits light. Specifically, if a state in which the main light emitting section 41 is turned off and only the auxiliary light emitting section 42 emits light is defined as the first light emitting state, each time the operating section 43 is pressed once from the first light emitting state, the main light emitting It is possible to transition from a second light emitting state to a fifth light emitting state in which only the portion 41 emits light at a first light emitting amount to a fourth light emitting amount. Here, the amount of light emission increases from the first amount of light emission to the fourth amount of light emission. Next, the user can return to the first light emitting state from the fifth light emitting state by pressing the operation unit 43 once. However, the number of stages of the light emission amount of the main light emitting section 41 and the method of transition of the light emission state can be changed as appropriate according to the specifications of the headlight 100.

The lid portion 44 is located at the left end of the main body case member 40 and constitutes a part of the outer shape of the main body case member 40. A space is formed in the lid portion 44 to cover a portion of the battery case portion 45 and the socket portion 53. The lid part 44 is removable from the battery case part 45. The user removes the lid part 44 from the battery case part 45 when replacing the battery housed in the battery case part 45, and attaches the lid part 44 to the battery case part 45 after replacing the battery.

Next, the battery case section 45 will be explained.
The battery case portion 45 is located from the center to the right end of the main body case member 40 and constitutes a part of the outer shape of the main body case member 40. In the battery case section 45, the above-described main light emitting section 41, auxiliary light emitting section 42, and operation section 43 are arranged. The battery case section 45 of this embodiment can accommodate batteries of two different sizes. Specifically, the battery case portion 45 can accommodate either an AA battery or a AAA battery. AA batteries and AAA batteries are cylindrical and have a positive terminal at one end and a negative terminal at the other end. AA batteries have a longer overall length and a larger diameter than AAA batteries.

As shown in FIG. 2E, the battery case 45 has a storage space 46 that is open on the left side. The storage space 46 is recessed from the opening toward the right side in a generally cylindrical shape. In each figure, the central axis of the cylinder that forms the storage space 46 is indicated by a dashed line. Either an AA battery B3 or an AAA battery B4 is stored inside the storage space 46. The storage space 46 has a terminal 47 at the right end inside. The terminal 47 functions as a contact point that contacts the negative terminal of the battery. In this embodiment, the terminal 47 contacts the negative terminal of the AA battery B3 when the battery stored in the storage space 46 is an AA battery B3, and contacts the negative terminal of the AAA battery B4 when the battery is an AAA battery B4. The terminal 47 in this embodiment uses a compression coil spring, but the configuration of the terminal 47 is not particularly limited.

Furthermore, a conductive metal plate 48 connected to a terminal 47 is wired to the right end of the housing space 46 . The metal plate 48 is connected to a substrate 49 that controls the light emission state of the main light emitting section 41 and the auxiliary light emitting section 42 . On the other hand, a conductive metal plate 50 is wired along the inner surface of the housing space 46 from the left end to the center of the housing space 46 . Metal plate 50 is connected to substrate 49.
Further, a guide portion 51 is formed along the inner surface of the housing space 46 from the left end to the right end of the housing space 46 . The guide section 51 guides the movement of the link section 66 in the left-right direction.

The left end of the battery case 45 has an engaged portion 52 that engages with an engaging portion 62 (described later) of the socket 53. The engaged portion 52 is a hole that penetrates from the inner surface of the storage space 46 to the outer surface. The engaged portions 52 are configured as a pair, one at the front and one at the back of the storage space 46, with the central axis of the storage space 46 in between.

Next, the socket portion 53 will be described.
3A and 3B are diagrams showing an example of the configuration of the socket portion 53, where FIG. 3A is a side view of the socket portion 53 seen from the left side, and FIG. 3B is a side view of the socket portion 53 seen from the right side.
The socket portion 53 is fitted into the battery case portion 45 to support a battery housed in the housing space 46 of the battery case portion 45. The socket portion 53 of this embodiment has two support portions (a first support portion 54a and a second support portion 54b) corresponding to the size of the battery housed in the battery case portion 45. The first support portion 54a supports a AA battery B3, and the second support portion 54b supports a AAA battery. The socket portion 53 is capable of switching its position so that the support portion corresponding to the battery housed in the battery case portion 45, either the first support portion 54a or the second support portion 54b, supports the battery.

Specifically, the socket portion 53 is formed in a cylindrical shape. The socket portion 53 has a size such that a portion thereof can be inserted into the accommodation space 46 of the battery case portion 45. By inserting the socket part 53 into the accommodation space 46 of the battery case part 45, the two are fitted together. In each figure, the central axis of the cylinder forming the socket portion 53 is shown by a chain line. A first support portion 54a is located on one side of the socket portion 53 in the axial direction, and a second support portion 54b is located on the other side.
The first support portion 54a has a first recess 55a that is recessed in a cylindrical shape from one end in the axial direction toward the other end. The end of the positive terminal side of the AA battery B3 can be inserted into the first recess 55a. The first recess 55a has a length (depth) La of approximately 10 mm to 15 mm, and an inner diameter Da of approximately 14 mm to 16 mm (see FIG. 2E).
The second support portion 54b has a second recess 55b recessed in a cylindrical shape from the other end in the axial direction toward one side. The end of the positive terminal side of the AAA battery B4 can be inserted into the second recess 55b. The second recess 55b has a length (depth) Lb of approximately 7 mm to 10 mm, and an inner diameter Db of approximately 10 mm to 13 mm (see FIG. 2E). Note that since the second recess 55b is smaller than the first recess 55a, it is not possible to insert the positive terminal side end of the AA battery B3, which is larger in size than the AAA battery B4.

Further, the socket portion 53 has a partition portion 56 that partitions the first recess 55a and the second recess 55b. The partition portion 56 is located between the first recess 55a and the second recess 55b. When the positive terminal side end of the AA battery B3 is inserted into the first recess 55a, the end surface located around the positive terminal of the AA battery B3 comes into contact with one surface of the partition 56. When the end of the AAA battery B4 on the positive terminal side is inserted into the second recess 55b, the end surface around the positive terminal of the AAA battery B4 comes into contact with the other surface of the partition 56. The partition part 56 has an annular shape when the socket part 53 is viewed along the axial direction, and has a through hole 57 formed in the center.

The partition 56 has a terminal 58 in the through hole 57. The terminal 58 functions as a contact point that contacts the positive terminal of the battery. The terminal 58 in this embodiment is generally plate-shaped, and when the end of the positive terminal side of the AA battery B3 is inserted into the first recess 55a, the positive terminal of the AA battery B3 abuts against one side of the terminal 58, and when the end of the positive terminal side of the AAA battery B4 is inserted into the second recess 55b, the positive terminal of the AAA battery B4 abuts against the other side of the terminal 58. The terminal 58 in this embodiment is composed of a pair of leaf spring pieces 59a, 59b spaced apart from each other in the front and rear to improve flexibility, but the configuration of the terminal 58 is not particularly limited.
Terminal 58 is located between one surface and the other surface of partition 56. Therefore, even if the end of the negative terminal side of the battery is mistakenly inserted into first recess 55a or second recess 55b, the end face of the negative terminal side of the battery comes into contact with partition 56 first, so that the negative terminal is prevented from coming into contact with terminal 58.

The socket portion 53 has a conductive metal plate 60 connected to the terminal 58 wired between one surface and the other surface of the partition portion 56. The metal plate 60 is arranged to surround the terminal 58 from the front, back, top and bottom, and has an exposed portion 61 at its upper end. The exposed portion 61 is exposed from the outer peripheral surface of the socket portion 53, and functions as a contact point that comes into contact with the metal plate 50 when the socket portion 53 is fitted into the battery case portion 45. The exposed portion 61 is positioned offset from the upper end of the metal plate 60 toward the first support portion 54a.

Further, the socket portion 53 has an engaging portion 62 on its outer circumferential surface that engages with the engaged portion 52 of the battery case portion 45 (see FIGS. 2A to 2C). The engaging portion 62 is a protrusion that projects in the radial direction from the outer peripheral surface. Note that the engaging portions 62 are configured as a pair in the front and rear with the central axis of the socket portion 53 interposed therebetween. When the socket part 53 and the battery case part 45 are fitted together, the protrusion of the engaging part 62 enters the hole of the engaged part 52, so that the engaging part 62 engages with the engaged part 52.

The socket portion 53 also has finger hooks 63a, 63b on its outer circumferential surface for a user to hook their fingers (or nails) on in order to pull the socket portion 53 out of the battery case portion 45 when it is fitted into the battery case portion 45. The finger hook 63a is located on the first support portion 54a side and is a hole that penetrates from the outer circumferential surface to the inner circumferential surface. The finger hook 63b is located on the second support portion 54b side and is a groove that is recessed from the outer circumferential surface toward the central axis of the socket portion 53. The finger hooks 63a, 63b are configured as a pair, one in front of the other and one in back of the central axis of the socket portion 53.

Further, the socket portion 53 has a connecting portion 64 that connects with a link portion 66 . The connecting portion 64 has a shaft shape that projects in the radial direction from the outer circumferential surface. The connecting portion 64 is located at the lower end of the outer peripheral surface. Specifically, in a state where the first support portion 54a of the socket portion 53 faces the battery case portion 45 (or the storage space 46), the connection portion 64 is located closer to the battery case portion 45 (or the storage space 46) than the terminal 58. 46). The socket portion 53 of this embodiment can change its posture while the link portion 66 is connected to the connecting portion 64. A specific operation when changing the posture of the socket portion 53 will be described later with reference to FIG. 4.

Next, the link portion 66 will be described.
The link portion 66 connects the socket portion 53 and the battery case portion 45. The link portion 66 is a member that is long along the left-right direction. The link portion 66 is flexible in a direction perpendicular to a straight line along the left-right direction, specifically in the up-down direction. The link portion 66 is made of a flexible material, such as a synthetic resin.

Further, the link portion 66 has a connected portion 67 at the left end. The connected portion 67 is connected to the connecting portion 64 of the socket portion 53 . The connected portion 67 is a hole penetrating in the vertical direction, into which the shaft-shaped connecting portion 64 is inserted. The connected portion 67 and the connecting portion 64 are relatively rotatable around the axis of the connecting portion 64. Therefore, the entire socket portion 53 is rotatable around the connecting portion 64.

Further, the link portion 66 has a slide portion 68 at the right end (see FIG. 2E). The slide portion 68 is connected to a guide portion 51 formed on the inner surface of the housing space 46 of the battery case portion 45 . As the slide portion 68 is guided by the guide portion 51, the link portion 66 is movable in the left-right direction. When the socket part 53 is fitted into the battery case part 45, the slide part 68 is located at the right end of the guide part 51. On the other hand, when the socket part 53 is pulled out from the battery case part 45, the slide part 68 is located at the center of the guide part 51 in the left-right direction.

Next, the operation of switching the position of the socket portion 53 of the main body case member 40 configured as described above will be described with reference to FIG.
FIG. 4 is a diagram for explaining the operation when switching the position of the socket portion 53. As shown in FIG.
As shown in Figure 4(a), first, the user pulls the socket portion 53 out of the battery case portion 45, thereby separating the battery case portion 45 and the socket portion 53. At this time, the link portion 66 moves in the left-right direction, and the portion that was located inside the storage space 46 is exposed to the outside of the storage space 46. In Figure 4(a), the first support portion 54a of the socket portion 53 is positioned so as to face the storage space 46, and the second support portion 54b is positioned on the opposite side of the storage space 46. The position of the socket portion 53 shown in Figure 4(a) corresponds to the position for supporting an AA battery B3 with the first support portion 54a.

As shown in FIG. 4(b), when changing the posture of the socket part 53, the user bends the link part 66 to move the socket part 53 away from the opening edge of the accommodation space 46. The socket part 53 is rotated by 180 degrees around the connecting part 64 of. By bending the link portion 66 in this manner, the socket portion 53 can be easily rotated without the user's fingers interfering with the opening edge of the accommodation space 46. Furthermore, as shown in FIG. 4(b), the user can move the socket part 53 away from the opening edge of the accommodation space 46 by bending the link part 66. A battery can be inserted into and removed from the space 46. Specifically, as shown in FIG. 4(b), the link part 66 can be bent at least to a position where the socket part 53 does not touch the central axis of the accommodation space 46, and furthermore, It can be bent to a position where the socket portion 53 does not touch when extended along the axis.

As shown in FIG. 4(c), by restoring the bending of the link part 66, the user positions the second support part 54b of the socket part 53 to face the accommodation space 46, and the first support part 54a is located on the opposite side of the accommodation space 46. The posture of the socket portion 53 shown in FIG. 4(c) corresponds to the posture for supporting the AAA battery B4 with the second support portion 54b.

Next, referring to FIGS. 5 and 6, a case will be described in which the attitude of the socket portion 53 of the main body case member 40 configured as described above is changed to support the AA battery B3 or the AAA battery B4. I will explain.
FIGS. 5(a-1) and 5(a-2) are cross-sectional views showing the case where the first support portion 54a of the socket portion 53 supports the AA battery B3. FIGS. 5(b-1) and 5(b-2) are cross-sectional views showing the case where the second support portion 54b of the socket portion 53 supports the AAA battery B4. FIG. 6A is a perspective view showing the state of the metal plate 60 when the first support portion 54a of the socket portion 53 supports the AA battery B3. FIG. 6(b) is a perspective view showing the state of the metal plate 60 when the second support portion 54b of the socket portion 53 supports the AAA battery B4.

As shown in FIG. 5(a-1), when the user wants to use the AA battery B3, the user inserts the AA battery B3 into the housing space 46 and the first support part 54a of the socket part 53 is The socket part 53 is positioned so as to face the accommodation space 46. Note that when the second support part 54b of the socket part 53 faces the accommodation space 46, the user bends the link part 66 as described above in FIG. 4(b) and then removes the socket part. By rotating the socket part 53 around the connecting part 64 of the socket part 53, the attitude of the socket part 53 is changed.
Next, as shown in FIG. 5(a-2), the user fits the socket part 53 into the battery case part 45 by pushing the socket part 53 into the accommodation space 46. At this time, the engaging portion 62 of the socket portion 53 engages with the engaged portion 52 . By fitting the socket part 53 into the battery case part 45, the end of the positive terminal side of the AA battery B3 is inserted into the first recess 55a of the socket part 53, and the first support part 54a is inserted into the first recess 55a of the AA battery B3. Supports battery B3. Further, the end surface around the positive terminal of the AA battery B3 contacts the partition portion 56, and the positive terminal contacts the terminal 58.

Furthermore, the exposed portion 61 of the metal plate 60 connected to the terminal 58 is connected to the metal plate 50 wired to the battery case portion 45 . Note that when inserting the AA battery B3 into the first recess 55a of the socket portion 53, the position of the terminal 58 is shifted to the left compared to when inserting the AAA battery B4 into the second recess 55b. However, as shown in FIG. 6(a), the position of the exposed portion 61 of the metal plate 60 connected to the terminal 58 is shifted to the right from the upper end of the metal plate 60, so that the exposed portion 61 is not connected to the metal plate 60. can be connected.
Therefore, the positive terminal of the AA battery B3 is connected from the terminal 58 to the substrate 49 through the metal plate 60, the exposed portion 61, and the metal plate 50, and the negative terminal of the AA battery B3 is connected from the terminal 47 to the metal plate 48. Since it is connected to the board 49, power can be supplied from the AA battery B3 to the main light emitting section 41 and the auxiliary light emitting section 42 via the board 49.

On the other hand, as shown in FIG. 5(b-1), when the user wants to use the AAA battery B4, the user inserts the AAA battery B4 into the accommodation space 46 and inserts the battery into the second support part of the socket part 53. The socket part 53 is positioned so that the socket part 54b faces the accommodation space 46. Note that when the first support part 54a of the socket part 53 faces the accommodation space 46, the user bends the link part 66 as described above in FIG. The attitude of the socket part 53 is changed by rotating the socket part 53 around the connecting part 64 of the socket part 53.
Next, as shown in FIG. 5(b-2), the user fits the socket part 53 into the battery case part 45 by pushing the socket part 53 into the accommodation space 46. At this time, the engaging portion 62 of the socket portion 53 engages with the engaged portion 52 . By fitting the socket part 53 into the battery case part 45, the end of the positive terminal side of the AAA battery B4 is inserted into the second recess 55b of the socket part 53, and the second support part 54b is inserted into the second recess 55b of the AAA battery B4. Supports battery B4. Further, the end surface around the positive terminal of the AAA battery B4 contacts the partition portion 56, and the positive terminal contacts the terminal 58.

Furthermore, the exposed portion 61 of the metal plate 60 connected to the terminal 58 is connected to the metal plate 50 wired to the battery case portion 45 . Note that when inserting the AAA battery B4 into the second recess 55b of the socket portion 53, the position of the terminal 58 is shifted to the right side compared to when inserting the AA battery B3 into the first recess 55a. However, as shown in FIG. 6B, the position of the exposed portion 61 of the metal plate 60 connected to the terminal 58 is shifted to the left from the upper end of the metal plate 60, so that the exposed portion 61 is not connected to the metal plate 60. can be connected.

In this way, regardless of whether AA battery B3 or AAA battery B4 is used, the positive terminal of the battery is connected to substrate 49 from terminal 58 through metal plate 60, exposed portion 61, and metal plate 50. At the same time, the negative terminal of the battery is connected from the terminal 47 to the substrate 49 through the metal plate 48. Therefore, power can be supplied to the main light emitting section 41 and the auxiliary light emitting section 42 from the AA battery B3 or the AAA battery B4 via the substrate 49.

As described above, according to the present embodiment, the socket portion 53 is connected to the support portion of the two support portions 54a and 54b that corresponds to the battery accommodated in the battery case portion 45 while being connected by the link portion 66. The position can be changed to support the battery. Therefore, by changing the orientation of the socket section 53 depending on the battery accommodated in the battery case section 45, batteries of different sizes can be used. In particular, for the headlights 100 that may be used in emergencies or disasters, it is assumed that the user has only a few types of batteries for storage. It can increase the possibility of use.

Although the present invention has been described above along with the above-described embodiments, the present invention is not limited to the above-described embodiments, and modifications can be made within the scope of the present invention.
