Description

Hand light

[0001] This application claims priority to Japanese Patent Application No. 2023-108088, filed on June 30, 2023, the entire contents of which are incorporated herein by reference.

[0002] In recent years, the use of headlights has become mainstream at construction sites and other locations because they free up the user's hands. However, handheld flashlights (also called "flashlights") have the advantage that they allow the user to illuminate specific areas, such as narrow spaces or around the user, while maintaining the user's head position. For this reason, there is also a certain demand for handheld flashlights.

[0003] One method for carrying a flashlight while holding it close to the body is to attach it to the user's clothing using a clip provided on the flashlight (see, for example, Patent Document 1). Another carrying method is to store it in a case (see, for example, Patent Document 2).

[0004] Japanese Patent Application Laid-Open No. 11-7804 Japanese Patent Application Laid-Open No. 2005-199008

[0005] However, when the flashlight is tethered by a clip, it tends to be weak against the force of being pushed up from below. Therefore, when the flashlight is tethered by a clip, there is a risk that the clip will come off from clothing (e.g., a pocket or belt) and the flashlight will fall off. Furthermore, when the flashlight is stored in a case, the flashlight is stored inside the case, which tends to make it difficult to remove. In particular, when the flashlight is stored with other tools, it may become even more difficult to remove if it gets mixed up with the other tools.

[0006] An object of the present invention is to provide a hand light that can be securely carried using a holder and is easy to handle.

[0031] Hereinafter, a handheld light as an exemplary embodiment of the present invention will be described with reference to the drawings.

[0032] Fig. 1 shows a perspective view of a handheld light 1, which is an exemplary embodiment of the present invention. In Fig. 1, the handheld light 1 is shown from the side of the head 3 of the light-emitting device 2, which will be described later. In Fig. 1, the handheld light 1 is shown in a state in which a bracket 6, which will be described later, is housed in the light-emitting device 2 and is ready for use.

[0033] The handheld light 1, also known as a flashlight, can be held by a user to illuminate a desired location. The handheld light 1 includes, for example, a bracket 6 that can be attached to and detached from a holder 100 (described below) attached to the user's side. By attaching the bracket 6 to the holder 100, the handheld light 1 can be carried close to the user's body. Furthermore, by removing the bracket 6 from the holder 100 and separating the handheld light 1 from the user's side, the handheld light 1 can be used independently.

[0034] The handheld light 1 includes a light-emitting device 2 having a light-emitting portion 2a.

[0035] In Fig. 1, symbol O2 denotes the central axis of the light emitting device 2. The light emitting device 2 extends along the direction in which the axis O2 extends (hereinafter also referred to as the "axial direction"). In this embodiment, the light emitting device 2 has a cylindrical shape with the axis O2 as its central axis. However, the light emitting device 2 may also have a prismatic shape.

[0036] In this embodiment, the light-emitting device 2 includes a head 3, a body 4, and a tail 5. In this embodiment, the head 3 is disposed on the front side of the light-emitting device 2, and the tail 5 is disposed on the rear side of the light-emitting device 2. The body 4 is disposed between the head 3 and the tail 5. The body 4 includes a grip 4a that can be held by the user's hand. The body 4 also includes a power switch 11 for the light-emitting unit 2a.

[0037] The light-emitting unit 2a emits light to irradiate a target location. The light-emitting unit 2a is disposed at the front end of the head 3. The light source of the light emitted from the light-emitting unit 2a may be, for example, an LED (light-emitting diode). However, the light source of the light-emitting unit 2a is not limited to an LED. Examples of light sources include a resistance wire (incandescent light bulb) and a fluorescent tube (fluorescent bulb).

[0038] The handheld light 1 also includes a bracket 6 that is detachable from the holder 100 on the user side. The bracket 6 is attached to the light emitting device 2 so as to be swingable, as will be described in detail later.

[0039] In FIG. 2, the flashlight 1 is shown diagrammatically from the tail 5 side of the light emitting device 2 .

[0040] In this embodiment, the bracket 6 is disposed on the tail 5 .

[0041] In this embodiment, the bracket 6 includes an arm 61 rotatably attached to the light-emitting device 2. In this embodiment, the arm 61 is rotatably connected to a support portion 7 provided on the tail 5 of the light-emitting device 2 via a rotation shaft 8.

[0042] Fig. 3 shows an enlarged view of the periphery of the tail 5 of the light-emitting device 2 of the flashlight 1. In Fig. 3, the bracket 6 is housed in the tail 5 of the light-emitting device 2. Fig. 4 also shows an enlarged view of the periphery of the tail 5 of the light-emitting device 2. However, in Fig. 4, the bracket 6 is exposed from the tail 5 of the light-emitting device 2 by rotating an arm 61 provided on the bracket 6 outward around the rotation axis 8.

[0043] In this embodiment, the rotating shaft 8 is disposed outside the outer peripheral surface of the tail 5. In this embodiment, the rotating shaft 8 is rotatably supported by a support portion 7 provided on the tail 5. In this embodiment, the support portion 7 protrudes radially outward from the outer peripheral surface of the tail 5. Here, the "radial direction" refers to a direction perpendicular to the direction in which the axis O2 extends. In addition, the side in the radial direction that is closer to the axis O2 is referred to as the "radially inner side." Furthermore, in the radial direction, the side farther from the axis O2 is referred to as the "radially outer side." In this embodiment, the rotating shaft 8 is disposed radially outward from the outer peripheral surface of the tail 5.

[0044] In this embodiment, the bracket 6 can rotate together with the rotation shaft 8 fixed to the arm 61 relative to the support portion 7 provided on the tail 5. That is, in this embodiment, the bracket 6 can rotate together with the rotation shaft 8 relative to the light-emitting device 2. As a result, in this embodiment, the bracket 6 can swing relative to the light-emitting device 2 around the rotation shaft 8 as a base point between the open state shown in FIG. 4 and the closed state shown in FIG. 3. Also, in this embodiment, the bracket 6 can swing relative to the light-emitting device 2 around the rotation shaft 8 as a base point between the closed state shown in FIG. 3 and the open state shown in FIG. 4. That is, in this embodiment, the bracket 6 can swing around the rotation shaft 8 as a base point between the closed state shown in FIG. 3 and the open state shown in FIG. 4. However, the rotation shaft 8 may be configured to rotate relatively to the arm 61 of the bracket 6 and the support portion 7.

[0045] Referring to FIG. 4, the bracket 6 includes a bracket base 6a connected to an arm 61, a bracket neck 6b provided on the bracket base 6a, and a bracket flange 6c provided on the bracket neck 6b.

[0046] In this embodiment, the arm 61 is formed into a plate shape together with the bracket base 6a. In this embodiment, the bracket base 6a is disposed inside the bracket 6. In other words, in this embodiment, the bracket base 6a is disposed at a portion of the bracket 6 that is closest to the light emitting device 2 when the bracket 6 is attached to the light emitting device 2. Furthermore, in this embodiment, the bracket flange 6c is disposed at an outer side of the bracket 6. In other words, in this embodiment, the bracket flange 6c is disposed at a portion of the bracket 6 that is farthest from the light emitting device 2 when the bracket 6 is attached to the light emitting device 2. Furthermore, in this embodiment, the bracket neck 6b is disposed in the middle of the bracket 6. In other words, in this embodiment, the bracket neck 6b is disposed at a portion of the bracket 6 between the bracket base 6a and the bracket flange 6c.

[0047] In this embodiment, the bracket 6 has a contact surface F6 that contacts the outer surface of the light emitting device 2.

[0048] 4, in this embodiment, the contact surface F6 of the bracket 6 contacts the bottom surface F5 of the light emitting device 2, which is indicated by a dashed line. When the contact surface F6 contacts the bottom surface F5, the bracket 6 is received in the tail 5 of the light emitting device 2, as shown in FIG.

[0049] Furthermore, Fig. 5 shows the flashlight 1 of Fig. 3 in a plan view from the tail 5 side, and Fig. 6 shows the flashlight 1 of Fig. 4 in a plan view from the tail 5 side.

[0050] As shown in Fig. 5, in this embodiment, the bracket 6 has a circular external shape centered on the axis O2 when viewed in the axial direction. However, the bracket 6 may have a polygonal external shape when viewed in the axial direction. Also, referring to Fig. 6, in this embodiment, the bracket neck 6b has a smaller diameter than the bracket base 6a and the bracket flange 6c. As a result, as will be described later, the bracket neck 6b guides the bracket 6 into the holder 100. Furthermore, the bracket base 6a and the bracket flange 6c slidably engage the bracket 6 in the holder 100, as will be described later.

[0051] Furthermore, in this embodiment, the flashlight 1 is provided with a fixing portion 9 that removably fixes the bracket 6 to the light-emitting device 2 when the contact surface F6 of the bracket 6 comes into contact with the bottom surface F5 of the light-emitting device 2.

[0052] In this embodiment, the fixing portion 9 is formed by a combination of metal and a magnet. In this embodiment, the first fixing portion 9a provided on the bracket 6 is formed by metal. In contrast, in this embodiment, the second fixing portion 9b provided on the bottom surface F5 of the light-emitting device 2 is formed by a magnet. As a result, in this embodiment, when the contact surface F6 of the bracket 6 is brought into contact with the bottom surface F5 of the light-emitting device 2, the bracket 6 is removably fixed to the bottom surface F5 of the light-emitting device 2 by the magnetic force generated between the first fixing portion 9a and the second fixing portion 9b. However, in this embodiment, while the first fixing portion 9a is formed by a magnet, the second fixing portion 9b can be formed by metal.

[0053] Furthermore, the fixing portion 9 may be provided at a location other than the bottom surface F5. For example, the fixing portion 9 may be configured to be mechanically coupled by press-fitting, fitting using recesses and protrusions, or locking. For example, in the case of press-fitting, at least one of the outer peripheral surface of the bracket base 6a of the bracket 6 and the inner surface of the tail 5 (specifically, the inner surface of the protective cover 5a described below) may be coated with a high-friction material (for example, silicone, rubber, or elastomer).

[0054] Furthermore, when the fixing portion 9 is fitted or locked by, for example, recesses and projections, a hook can be provided on one of the outer surface of the bracket base 6a of the bracket 6 and the inner surface of the tail 5 (as a specific example, the inner surface of the protective cover 5a described later) to fit or lock onto the other side.

[0055] Furthermore, the fixing portion 9 can be configured by two gears that mesh with each other and are provided on the rotating shaft 8 and the support portion 7, respectively. In this case, the fixing portion 9 has two gears, one of which is a fixed gear and the other of which is a rotating gear that can ride over the teeth of the fixed gear. In this case, for example, if the gear on the bracket 6 (e.g., arm 61) side is a rotating gear and the gear on the light-emitting device 2 (e.g., support portion 7) side is a fixed gear, the teeth of the rotating gear can sequentially ride over the teeth of the fixed gear, thereby fixing the bracket 6 at a desired position (desired angle α).

[0056] However, if the fixing part 9 is made of a combination of metal and a magnet, it is advantageous in terms of durability, since it can function as the fixing part 9 for a longer period of time.

[0057] Furthermore, the flashlight 1 according to this embodiment includes a biasing member 10 that applies a biasing force to the bracket 6 so as to rotate the bracket 6 in a direction away from the light-emitting device 2. As shown in Fig. 4, the biasing member 10 biases the bracket 6 in a direction away from the light-emitting device 2. As a result, the bracket 6 assumes an initial state in which it is open from the bottom surface F5 of the light-emitting device 2, as shown in Fig. 4.

[0058] Referring to FIG. 4 , in this embodiment, the symbol α is the angle formed between the contact surface F6 of the bracket 6 and the bottom surface F5 of the light-emitting device 2 when the bracket 6 is rotated in a direction away from the bottom surface F5 of the light-emitting device 2. The angle α is preferably equal to or greater than 90 degrees. More preferably, the angle α exceeds 90 degrees. Specific examples of the angle α include a range of 100 degrees to 150 degrees. In this embodiment, the angle α is 110 degrees.

[0059] FIG. 7 schematically illustrates an example of the biasing member 10. As shown in FIG. 7, in this embodiment, the biasing member 10 is a torsion spring. The biasing member 10 includes a bracket-side extending portion 10a, one coil portion 10c, and a light-emitting device-side extending portion 10b. In this embodiment, the bracket-side extending portion 10a is set to be longer than the light-emitting device-side extending portion 10b. In this embodiment, the biasing member 10 is formed by integrally forming the bracket-side extending portion 10a, one coil portion 10c, and the light-emitting device-side extending portion 10b using a single wire rod.

[0060] Fig. 8 shows a perspective view of the bracket 6 (hereinafter also referred to as "bracket swinging body 6A") equipped with an arm 61 of the handheld light 1, viewed from the bracket flange 6c side. Fig. 9 also shows a perspective view of the bracket swinging body 6A viewed from the contact surface F6 side of the bracket 6.

[0061] In this embodiment, the arm 61 has two knuckles 61a as extending end portions from the bracket 6. The two knuckles 61a are spaced apart in the width direction of the arm 61. Each of the two knuckles 61a has a through hole 62 for attaching the rotating shaft 8. In addition, as shown in FIG. 9 , a bracket-side accommodation groove 63 is formed in the arm 61. The bracket-side accommodation groove 63 can accommodate the bracket-side extending portion 10a of the urging member 10 so that the bracket-side extending portion 10a is embedded in the contact surface F6 of the bracket 6. In this embodiment, the bracket-side accommodation groove 63 is formed on the inner surface F61 of the arm 61 that is continuous with the contact surface F6 of the bracket 6. As a result, as shown in FIG. 6 , the urging member 10 is assembled to the bracket rocking body 6A in a state where it is embedded in the bracket rocking body 6A.

[0062] FIG. 10 is a perspective view of the tail 5 of the light-emitting device 2 of the flashlight 1, along with the support portion 7. In this embodiment, the support portion 7 is formed with a through-hole 72 for rotatably supporting the rotation shaft 8. This allows the bracket rocking body 6A to rotate relative to the support portion 7 together with the rotation shaft 8. However, the rotation shaft 8 can be fixed to the support portion 7. In this case, the bracket rocking body 6A rotates relative to the rotation shaft 8. In addition, as shown in FIG. 10 , the support portion 7 is formed with a light-emitting device-side accommodating groove 73. The light-emitting device-side accommodating groove 73 is formed on the side surface of the support portion 7. The light-emitting device-side accommodating groove 73 can accommodate the light-emitting device-side extending portion 10b and the coil portion 10c of the biasing member 10 so that the light-emitting device-side extending portion 10b and the coil portion 10c are embedded in the support portion 7. As a result, the biasing member 10 is assembled to the support portion 7 while embedded in the support portion 7, as shown in FIG. 3 .

[0063] That is, in this embodiment, the biasing member 10 can be assembled between the light emitting device 2 and the bracket rocking body 6A (bracket 6) in a state where it is embedded in both the bracket-side accommodating groove 63 formed in the bracket rocking body 6A and the light emitting device-side accommodating groove 73 formed in the support part 7. This allows the flashlight 1 to be made more compact.

[0064] Additionally, the tail 5 includes an attachment hole 74. Referring to Fig. 10, in this embodiment, the attachment hole 74 is formed in the support part 7. The attachment hole 74 penetrates the support part 7 in the width direction of the support part 7. The attachment hole 74 can be used to attach accessories including, for example, a safety rope, a carabiner, or other attachment hardware.

[0065] In this embodiment, the light emitting device 2 further includes a protective cover 5a that protects the bracket 6. In this embodiment, the protective cover 5a protects the bracket 6 that is disposed on the bottom surface F5 of the light emitting device 2.

[0066] In this embodiment, the protective cover 5a is formed integrally with the tail 5. In this embodiment, the protective cover 5a stands upright from the bottom surface F5 of the light-emitting device 2 toward the rear in the axial direction. For example, as shown in FIG. 3 , in this embodiment, the protective cover 5a protects the bracket 6 from the outside by covering the entire bracket 6 housed in the light-emitting device 2 in the axial direction. However, the protective cover 5a may also protect the bracket 6 from the outside by partially covering a portion of the bracket 6 in the axial direction.

[0067] Referring to FIG. 2 , in this embodiment, the light emitting device 2 includes two protective covers 5a. Two gaps 5c are formed between the two protective covers 5a. One of the two gaps 5c, a first gap 5c1, is a gap for preventing interference between the arm 61 of the bracket rocking body 6A and the protective cover 5a. That is, in this embodiment, the first gap 5c1 is a gap for allowing the arm 61 to pass through when the bracket rocking body 6A is rotated. Furthermore, in this embodiment, the other of the two gaps 5c, a second gap 5c2, is a gap for allowing a user to rotate the bracket rocking body 6A. The second gap 5c2 is a gap for inserting the user's finger when rotating the bracket rocking body 6A. However, the second gap 5c2 may be omitted if the protective cover 5a is configured to partially cover a portion of the bracket 6 in the axial direction.

[0068] The protective cover 5a may be a cylindrical protective cover extending annularly in the circumferential direction around the axis O2. In this embodiment, the gaps 5c are notches formed in the cylindrical protective cover 5a. However, the gaps 5c do not have to be formed by notches as long as the protective cover 5a is formed at intervals in the circumferential direction around the axis O2. For example, each of the multiple protective covers 5a may be independently and locally provided on the bottom surface F5 of the light-emitting device 2. In this case, the gaps 5c are formed by gaps between the multiple protective covers 5a that locally protrude from the bottom surface F5 of the light-emitting device 2.

[0069] Here, Fig. 11 shows a holder 100 from the front as an example of a holder to which the flashlight 1 can be attached, and Fig. 12 shows the holder 100 of Fig. 11 from the side.

[0070] The holder 100 includes a holding portion 110 that detachably holds the flashlight 1, and a plate-shaped portion 120 attached to the holding portion 110. As shown in Fig. 12, the holder 100 can be attached to a belt B worn by a user by passing the belt B between the holding portion 110 and the plate-shaped portion 120.

[0071] In the holder 100 , the holding portion 110 includes a main body portion 111 , a stopper member 112 , and a safety rope attachment portion 113 .

[0072] 11 , the main body 111 of the holder 110 has a notch 111d that defines a holding position 100s where the bracket 6 of the flashlight 1 is held and that guides the bracket 6 to the holding position 100s. In this example, the two notches 111d that face each other in the width direction are arranged on the main body 111 so as to extend in the vertical direction when the user is wearing the holder 100. In this embodiment, the upper side of the space between the two notches 111d is open and the lower side is closed.

[0073] As shown in FIG. 12 , the main body 111 of the holder 110 includes a base plate 111a and a sub-plate 111b. In this example, the sub-plate 111b is attached to the front side of the base plate 111a at a distance from the base plate 111a. This creates a gap between the base plate 111a and the sub-plate 111b, allowing the bracket flange 6c of the bracket 6 to be inserted. Furthermore, in this example, a U-shaped notch 111d is formed in the sub-plate 111b, as shown in FIG. 11 . The notch 111d slidably guides the bracket neck 6b of the bracket 6. Furthermore, the outer edge of the notch 111d is slidably held between the bracket base 6a and the bracket flange 6c of the bracket 6. As a result, the notch 111d guides the flashlight 1 via the bracket 6 to the holding position 100s and positions it at the holding position 100s.

[0074] In addition, the stopper member 112 of the holding portion 110 removably fixes the bracket 6 at the holding position 100s. In this example, the stopper member 112 has an initial position indicated by the dashed line in FIG. 11 . The stopper member 112 is biased to the position indicated by the dashed line in FIG. 11 by, for example, using a coil spring (not shown) disposed between the main body 111 and the stopper member 112. As a result, when the stopper member 112 is in the initial state indicated by the dashed line in FIG. 11 , the stopper member 112 closes the upper opening formed between the two notches 111d. However, the stopper member 112 can slide diagonally downward and left relative to the main body 111 against the biasing force (elastic force) of the coil spring. As a result, the upper opening formed between the two notches 111d is opened without being obstructed by the stopper member 112.

[0075] Fig. 13 is a schematic front view of the flashlight 1 attached to the holder 100. Fig. 14 is a schematic side view of the attached state of Fig. 13.

[0076] For example, the flashlight 1 can be attached to the holder 100 by the following procedure.

[0077] The flashlight 1 can be used by, for example, storing the bracket 6 in the tail 5 of the light-emitting device 2, as shown in FIG. 3 . After using the flashlight 1, when attaching the flashlight 1 to a holder 100 attached to a belt B, the bracket 6 is opened from the bottom surface F5 of the light-emitting device 2, as shown in FIG. 4 . In this embodiment, the bracket 6 is fixed to the bottom surface F5 of the light-emitting device 2 by the magnetic force of the fixing portion 9. Therefore, the user pulls up the bracket 6 with a force that resists the magnetic force of the fixing portion 9. In this embodiment, when the bracket 6 is pulled up against the magnetic force of the fixing portion 9, the bracket 6 can automatically open as shown in FIG. 4 due to the biasing force of the biasing member 10. In particular, in this embodiment, the user can hook the bracket 6 by inserting a finger inside the protective cover 5a through the second gap 5c2.

[0078] Next, referring to FIG. 11 , the user attaches the bracket 6, which has been opened from the light-emitting device 2, to the holder 100. The user presses down on the bracket 6 of the flashlight 1 from above the stopper member 112 of the holder 100. At this time, the bracket neck 6 b of the bracket 6 slides the stopper member 112, shown by the dashed line, to the position shown by the solid line. This allows the bracket neck 6 b to move along the two notches 111 d to the holding position 100 s of the main body 111. When the bracket neck 6 b moves to the holding position 100 s, the stopper member 112 returns to the position shown by the dashed line due to the biasing force of the coil spring. FIG. 13 shows the stopper member 112 returned to its initial state. This prevents the bracket 6 of the flashlight 1 from coming loose from the holder 100.

[0079] As shown in Figure 13, with the flashlight 1, the flashlight 1 can be attached to the holder 100 simply by inserting the bracket 6, which opens from the bottom surface F5 of the light-emitting device 2, into the notch 111d, and then moving it along the notch 111d to the holding position 100s of the main body 111.

[0080] Furthermore, the flashlight 1 attached to the holder 100 can be easily removed from the holder 100 by simply pushing the stopper member 112 diagonally downward to the left and then pulling the flashlight 1 upward.

[0081] As described above, the flashlight 1 includes the light-emitting device 2 with the light-emitting unit 2a and the bracket 6 that is detachable from the holder 100 on the user's side, and the bracket 6 is attached so as to be able to swing to the light-emitting device 2. The flashlight 1 is held in an exposed state on the outside of the holder 100, so that it can be attached and detached while being held directly in the hand. This allows for secure carrying using the holder and makes handling easy.

[0082] 14, the bracket 6 of the flashlight 1 is securely held by the holder 100. This prevents the flashlight 1 from falling off the holder 100 even if an external force is applied to the flashlight 1 while the flashlight 1 is being carried.

[0083] Furthermore, the flashlight 1 can be attached to and detached from the holder 100 while being held directly in the hand. In this case, there is no need to check the inside of the case, as is the case when storing the flashlight inside a case, making it easy to remove the flashlight. In particular, when a user carries the flashlight together with other tools, the flashlight 1 has a one-to-one correspondence with the holder 100. Therefore, when the flashlight 1 is carried together with other tools, the flashlight 1 will not get mixed up with the other tools. Therefore, when the flashlight 1 is carried together with other tools, it is easier to remove the flashlight 1.

[0084] Additionally, in the flashlight 1, the bracket 6 is attached to the light-emitting device 2 in a swingable manner. Therefore, the flashlight 1 can be swung relative to the holder 100 while the user is carrying the flashlight 1 via the holder 100 and performing other tasks. Specifically, even if an external force (load) is applied to the flashlight 1 when the user crouches down while carrying the flashlight 1, the external force (load) can be released by the flashlight 1 swinging relative to the holder 100. In other words, the flashlight 1 allows freedom of movement when attached to the holder 100. Therefore, the flashlight 1 can be carried in a manner that is less likely to interfere with the user's work. In particular, in this embodiment, the bracket neck 6b is circular (cylindrical), as shown in FIG. 9 . In this case, referring to FIG. 13 , the flashlight 1 can be rotated 360 degrees relative to the holder 100 while attached to the holder 100. This further reduces interference with the user's work.

[0085] In particular, in this embodiment, the bracket 6 includes an arm 61 rotatably attached to the light-emitting device 2. In this case, the bracket 6 of the flashlight 1 can be attached to the holder 100 by a simple operation of simply rotating the bracket 6 together with the arm 61 to open the bracket 6.

[0086] In this embodiment, the bracket 6 has a contact surface F6 that comes into contact with the outer surface of the light-emitting device 2. In this case, for example, as shown in Fig. 2, the flashlight 1 can be used with the bracket 6 housed in the light-emitting device 2. Therefore, if the bracket 6 is provided with a contact surface F6 that comes into contact with the outer surface of the light-emitting device 2, as in this embodiment, the flashlight 1 is easy to use.

[0087] 17 , the flashlight 1 according to this embodiment includes a fixing portion 9 that detachably fixes the bracket 6 to the light-emitting device 2 when the contact surface F6 of the bracket 6 comes into contact with the outer surface of the light-emitting device 2. In this case, the fixing portion 9 functions as an opening stopper to prevent the bracket 6 from opening in a manner unexpected by the user. Therefore, by providing fixing portions 9 on both the light-emitting device 2 and the bracket 6, as in this embodiment, the bracket 6 can be prevented from opening in a manner unexpected by the user. In particular, by configuring the fixing portion 9 using a combination of metal and a magnet, as in this embodiment, the fixing portion 9 can be easily formed and has good durability.

[0088] In this embodiment, the contact surface F6 of the bracket 6 comes into contact with the bottom surface F5 of the light-emitting device 2. In this case, for example, as shown in Fig. 2, the flashlight 1 can be used with the bracket 6 as part of the bottom surface F5 of the light-emitting device 2. Therefore, if the contact surface F6 of the bracket 6 comes into contact with the bottom surface F5 of the light-emitting device 2 as in this embodiment, the flashlight 1 becomes even easier to use.

[0089] 4, the flashlight 1 according to this embodiment is provided with a biasing member 10 that applies a biasing force to the bracket 6 so as to rotate the bracket 6 in a direction away from the light-emitting device 2. In this case, the bracket 6 can automatically open relative to the light-emitting device 2. In addition, in this case, the bracket 6 is maintained in an open state relative to the light-emitting device 2 in its initial state. Therefore, by providing the biasing member 10 that applies a biasing force to the bracket 6 as in this embodiment, the bracket 6 can be easily attached to and detached from the holder 100.

[0090] In addition, in this embodiment, when the bracket 6 is rotated in a direction away from the bottom surface F5 of the light-emitting device 2, the angle α formed between the contact surface F6 of the bracket 6 and the bottom surface F5 of the light-emitting device 2 is 90 degrees or more.

[0091] If the angle α is less than 90 degrees, the bracket 6 will tend to close toward the light-emitting device 2 (toward the bottom surface F5 of the light-emitting device 2). In contrast, if the angle α is 90 degrees or greater, more preferably greater than 90 degrees, the bracket 6 will not easily close toward the light-emitting device 2 even when a force in a closing direction is applied to the bracket 6. Therefore, if the angle α is greater than 90 degrees, for example, 110 degrees, as in this embodiment, the bracket 6 will not easily close, making it easier to attach and detach the bracket 6 to and from the holder 100.

[0092] In particular, in this embodiment, the bracket 6 opens at an angle exceeding 90 degrees relative to the bottom surface F5 of the light-emitting device 2. Therefore, as shown in FIG. 14 , when the flashlight 1 is attached to a user via the holder 100, a gap S can be formed between the flashlight 1 and the user (body side). The user's fingers or hand can be inserted into the gap S. The gap S also reduces the contact area between the user (body) and the flashlight 1. Therefore, the gap S facilitates handling of the flashlight 1 attached to the holder 100. For example, see FIG. 2 . The radially outer rear surface 7s of the support portion 7 is formed as a stopper surface that can come into contact with the arm 61 when the bracket 6 is opened. As a result, when the bracket 6 is opened, the arm 61 can open to the angle α by contacting the radially outer rear surface 7s of the support portion 7.

[0093] 2, for example, in this embodiment, the light emitting device 2 is provided with a protective cover 5a that protects the bracket 6. Providing the protective cover 5a as in this embodiment can prevent malfunction of the bracket 6, such as the bracket 6 accidentally opening. Providing the protective cover 5a as in this embodiment can also serve to prevent damage if the flashlight 1 is accidentally dropped, for example. Furthermore, providing the protective cover 5a as in this embodiment can also serve to prevent contamination, preventing the bracket 6 and the bottom surface F5 of the light emitting device 2 from becoming dirty.

[0094] In this embodiment, the bracket 6 is disposed on the tail 5. In this case, for example, as shown in FIG. 13 , when the flashlight 1 is attached to the holder 100, the flashlight 1 is attached to the holder 100 with the tail 5 of the light-emitting device 2 positioned on the upper side. In other words, the flashlight 1 is hung from the holder 100 so as to extend vertically with the head 3 facing downward. In this case, the user can remove the flashlight 1 from the holder 100 while holding the grip 4 a of the body 4 of the light-emitting device 2. This allows the flashlight 1 to be used as is after removing it from the holder 100. In this case, after using the flashlight 1, the user can attach the flashlight 1 to the holder 100 while holding the grip 4 a of the body 4 of the light-emitting device 2. Therefore, if the bracket 6 for attaching and detaching the flashlight 1 to the holder 100 is disposed on the tail 5 of the light-emitting device 2 as in this embodiment, the flashlight 1 can be easily handled.

[0095] 14 , for example, in this embodiment, the tail 5 of the light-emitting device 2 includes an attachment hole 74. In this case, an accessory (e.g., a safety rope or a metal attachment such as a carabiner) can be attached to the attachment hole 74. In particular, in this embodiment, the attachment hole 74 is formed in the support portion 7. When the attachment hole 74 is formed in the support portion 7 provided on the tail 5 as in this embodiment, the attachment hole 74 is located on the holder 100 side, i.e., on the user's body side, when the flashlight 1 is attached to the holder 100, as shown in FIG. 14 . In this case, when an accessory is attached to the attachment hole 74, the accessory is located inside the flashlight 1 (closer to the user), not outside the flashlight 1. Therefore, when the attachment hole 74 is formed in the support portion 7 provided on the tail 5 as in this embodiment, the accessory attached to the attachment hole 74 does not get in the way when the user grasps the flashlight 1. That is, if the attachment hole 74 is formed in the support part 7 provided on the tail 5 as in this embodiment, even when the accessory is attached to the attachment hole 74, the flashlight 1 can be easily grasped when attaching or detaching the flashlight 1 to or from the holder 100 and when using the flashlight 1. Therefore, if the attachment hole 74 is formed in the support part 7 provided on the tail 5 as in this embodiment, the flashlight 1 can be easily handled even when the accessory is attached to the attachment hole 74.

[0096] Although the rotation shaft 8 is disposed on the outer peripheral surface of the tail 5 of the light-emitting device 2, it can be disposed at any position on the tail 5.

[0097] 15A shows a schematic perspective view of another example of a bracket 6 equipped with an arm 61 together with the tail 5 of the light-emitting device 2. The bracket 6 equipped with the arm 61 shown in FIG. 15A (hereinafter also referred to as the "bracket rocker 6B") rotates together with the rotation shaft 8 on the bottom surface F5 of the tail 5. In this example, the support portion 7 extends from the bottom surface F5 of the tail 5 along the axis O2. In this example, the support portion 7 is disposed on a part of the outer periphery of the bottom surface F5 of the tail 5.

[0098] Next, FIG. 15B shows a schematic perspective view of an example of a bracket 6 having a shaft 65, along with a tail 5. In this example, the bracket 6 has a shaft 8 on its bracket base 6a, which is rotatable relative to the light-emitting device 2. The bracket 6 having the shaft 65 (hereinafter also referred to as a "bracket rocker 6C") shown in FIG. 15B has two shafts 65 on both sides (only one side is shown in FIG. 15B). The two shafts 65 are each arranged on an axis O65 passing through the radial center of the annular protective cover 5a. In this example, the bracket 6 rotates at least 180 degrees around the shaft 65 relative to the protective cover 5a. This allows the bracket 6 to rock relative to the light-emitting device 2 so that the bracket neck 6b and bracket flange 6c can be accommodated inside the protective cover 5a. Note that FIG. 15B shows only the bracket base 6a, and the bracket neck 6b and bracket flange 6c are omitted.

[0099] 15C is a schematic perspective view of an example of a bracket 6 equipped with a linear member 64. The bracket 6 equipped with a linear member 64 shown in FIG. 15C (hereinafter also referred to as a "bracket rocker 6D") is equipped with a deformable linear member 64. One end of the linear member 64 is connected to the bracket 6, and the other end of the linear member 64 is connected to the light-emitting device 2. The other end of the linear member 64 can be connected to, for example, the bottom surface F5 of the light-emitting device 2. Examples of the linear member 64 include flexible linear members such as a chain or a resin string.

[0100] FIG. 16 is a schematic cross-sectional view of the hand light 1 including the axis O2.

[0101] As shown in FIG. 16 , the flashlight 1 according to this embodiment includes a heater 13 in the light-emitting device 2. In this embodiment, the heater 13 is disposed radially inward of a grip (holding portion) 4a that is held by the user. In this embodiment, the grip 4a is one component of the body 4 of the light-emitting device 2. The grip 4a forms the basic external shape of the portion that is held by the user. In this embodiment, the grip 4a is a cylindrical metal member. In this embodiment, the grip 4a is made of an aluminum alloy. However, the grip 4a can be made of a material other than metal as long as it has good thermal conductivity.

[0102] 16 , in this embodiment, the body 4 of the light-emitting device 2 includes a center body 4b. In this embodiment, the center body 4b forms the basic external shape of the body 4. In this embodiment, the center body 4b is a cylindrical member. In this embodiment, a battery 15 is disposed inside the center body 4b, and applies current (voltage) to each of the light-emitting unit 2a and the heater 13. In this embodiment, the battery 15 is a rechargeable battery that can be removed from inside the center body 4b.

[0103] In this embodiment, the body 4 of the light emitting device 2 also includes a center base 4c. In this embodiment, the center base 4c serves as a base member for holding the grip 4a. In this embodiment, the center base 4c is also a cylindrical resin member. In this embodiment, the center base 4c is held by the center body 4b disposed therein.

[0104] In this embodiment, the heater 13 is disposed around the axis O2 of the light-emitting device 2. For example, the heater 13 may be a single heater extending in a band shape in the circumferential direction around the axis O2. Alternatively, the heater 13 may be a plurality of heaters disposed at intervals in the circumferential direction around the axis O2.

[0105] The heater 13 may be, for example, a printed circuit board (PCB). In this embodiment, the heater 13 is a flexible film heater. As a film heater, for example, a flexible printed circuit board (FPC) may be used. When the heater 13 is a film heater, the heater 13 may be attached along the inner circumferential surface of the grip 4a. In this embodiment, the heater 13 is a single film heater extending in a band shape in the circumferential direction around the axis O2.

[0106] In this embodiment, the heater 13 is disposed between the grip 4 a and the center base 4 c. In this embodiment, the heater 13 is disposed along the inner circumferential surface of the grip 4 a by being in contact with the inner circumferential surface of the grip 4 a.

[0107] Additionally, in this embodiment, the light-emitting device 2 includes a holding means (14) that holds the heater 13 on the inner surface side of the light-emitting device 2. In this embodiment, the holding means (14) generates a biasing force that presses the heater 13 against the inner surface of the grip 4a so that the heater 13 contacts the inner surface of the grip 4a.

[0108] In this embodiment, the holding means is an elastic member 14. In this embodiment, the elastic member 14 is a porous member having cushioning properties. In addition, in this embodiment, the elastic member 14 has heat insulating properties. A specific example of the elastic member 14 is a foamed resin member made of urethane resin or polyethylene resin.

[0109] In this embodiment, the holding means (holding member) 14 is assembled in a compressed state between the grip 4a and the center base 4c together with the heater 13. As a result, in this embodiment, the heater 13 is held pressed against the inner circumferential surface of the grip 4a by the elastic force (restoring force) of the holding member 14.

[0110] However, the holding means may be adhesive. In this case, the heater 13 may be adhered to the inner circumferential surface of the grip 4a, for example, via an adhesive. The holding means may also be mechanical. As a specific example, the holding means may be a hook provided on the inner circumferential surface of the grip 4a. In this case, the heater 13 can be engaged with the inner circumferential surface of the grip 4a by the hook. More specifically, the heater 13 is sandwiched between the inner circumferential surface of the grip 4a and the hook. This allows the heater 13 to be held in contact with the inner circumferential surface of the grip 4a.

[0111] Figure 19 shows the flashlight 1 with the grip (outer cylinder) 4a removed from the body 4 of the light-emitting device 2. In Figure 19, reference numeral 11 denotes a power switch for the light-emitting unit 2a. In this embodiment, the power switch 11 can be used to turn the light-emitting unit 2a on and off, as well as to gradually change the light intensity of the light-emitting unit 2a. In this embodiment, the light intensity can be changed between three levels: 500 lumens, 250 lumens, and 50 lumens.

[0112] FIG. 20 also shows the state in which the heater 13 has been removed from the body 4 of the light-emitting device 2 of FIG. 19 . FIG. 20 shows the opposite radial side (back side) of the flashlight 1 of FIG. 19 . In FIG. 20 , reference numeral 12 denotes a power switch for the heater 13. In this embodiment, the light-emitting device 2 is equipped with a power switch 11 for the light-emitting unit 2a and a power switch 12 for the heater 13, separately. Furthermore, in this embodiment, the power switch 11 for the light-emitting unit 2a and the power switch 12 for the heater 13 are positioned opposite each other across the axis O2 of the light-emitting device 2. In this embodiment, the power switch 12 can be used to turn the heater 13 on and off, as well as to gradually change the temperature of the heater 13. In this embodiment, the heater 13 can be switched between three temperatures, for example, 60°C, 50°C, and 40°C.

[0113] FIG. 21 is an exploded perspective view for schematically illustrating the internal structure of the body 4 of the light-emitting device 2 of the flashlight 1. As shown in FIG. 21 , in this embodiment, the holding member 14 is a sheet-shaped foam resin member. Also, in this embodiment, a recess 4c1 is formed in the outer peripheral surface of the center base 4c. Also, in this embodiment, a through-hole 4c2 is formed in the outer peripheral surface of the center base 4c. In this embodiment, the recess 4c1 extends circumferentially around the central axis of the center base 4c. In this embodiment, the holding member 14 is positioned on the center base 4c by being placed in the recess 4c1. In this embodiment, the holding member 14 is fixed to the recess 4c1 formed in the outer peripheral surface of the center base 4c using double-sided tape. Also, in this embodiment, the circumferential end 13e of the heater 13 and the circumferential end 14e of the holding member 14 are positioned opposite each other across the axis O2.

[0114] For example, as shown in Fig. 16, a flashlight 1 is provided with a heater 13 in the light-emitting device 2. In this case, the user can warm their hands by holding the flashlight 1. This is effective, for example, when working in cold regions, especially when performing precision work.

[0115] In particular, in this embodiment, the heater 13 is disposed in the grip 4a that is held by the user, so that the user can use the flashlight 1 without getting their hands cold.

[0116] 19, the heater 13 is disposed around the axis O2 of the light-emitting device 2. In this case, it is possible to heat a wider area around the flashlight 1. In particular, when the heater 13 is disposed on the grip 4a as in this embodiment, it is possible to warm the entire palm of the user's hand.

[0117] In this embodiment, the heater 13 is a flexible film heater. In this case, the heater 13 can be provided in the flashlight 1 while preventing the flashlight 1 from becoming larger. Furthermore, since the heater 13 can be freely deformed, there is a degree of freedom in the layout of the heater 13 inside the light-emitting device 2. Furthermore, since the heater 13 can be freely deformed, the heater 13 can be assembled in contact with the inner circumferential surface of the grip 4a.

[0118] In this embodiment, the light-emitting device 2 is also provided with a holding means (14) that holds the film heater on the inner surface of the light-emitting device 2. This allows the heater 13 to be reliably in contact with the inner surface of the grip 4a. In this case, the heat of the heater 13 can be efficiently transferred to the grip 4a.

[0119] In this embodiment, the holding means is an elastic member 14. In this case, by utilizing the repulsive force (restoring force) of the elastic member 14, the heater 13 can be more reliably brought into contact with the inner circumferential surface of the grip 4a. In this case, the heat of the heater 13 can be more efficiently transferred to the grip 4a.

[0120] Furthermore, in this embodiment, the elastic member 14 has heat insulating properties. In this case, the elastic member 14 can block heat transmitted to the inner region of the heater 13. For example, referring to FIG. 16 , in this embodiment, the battery 15 is disposed in the inner region of the heater 13. In this case, since the elastic member 14 blocks heat from the heater 13, deterioration of the battery 15 caused by the heat emitted from the heater 13 can be suppressed.

[0121] For example, in this embodiment, the battery 15 is a lithium ion battery. When the temperature around the lithium ion battery is too low, the power output of the lithium ion battery decreases. On the other hand, when the temperature around the lithium ion battery is too high, the power output of the lithium ion battery decreases.

[0122] In contrast, in this embodiment, the elastic member 14, which serves as a holding means for holding the heater 13, also has heat insulating properties. In this case, by appropriately selecting the heat insulating properties of the holding member 14, the temperature around the battery 15 can be kept at a temperature that has little effect on the battery 15. Therefore, by providing heat insulating properties to the elastic member 14, the battery 15 can be used efficiently.

[0123] As shown in FIG. 16 , in this embodiment, the light-emitting device 2 includes a power switch 11 for the light-emitting unit 2a and a power switch 12 for the heater 13. For example, the light-emitting unit 2a can be turned on and off by pressing and holding the power switch 11. Furthermore, in this embodiment, the light intensity can be switched in stages (three stages in this embodiment) by intermittently pressing the power switch 11. The heater 13 can also be turned on and off by pressing and holding the power switch 12. Furthermore, in this embodiment, the temperature of the heater 13 can also be switched in stages (three stages in this embodiment) by intermittently pressing the power switch 12. Furthermore, the operations corresponding to the power switch 11 and the power switch 12 are performed independently. Therefore, in this case, the function as the flashlight 1 and the function as the heater can be controlled independently.

[0124] Furthermore, as shown in FIG. 16 , in this embodiment, the power switch 11 of the light-emitting unit 2a and the power switch 12 of the heater 13 are arranged circumferentially around the axis O2 of the light-emitting device 2 and at the same axial position. In this case, the two power switches 11 and 12 can be arranged while minimizing the axial length of the light-emitting device 2, i.e., the flashlight 1. In particular, in this embodiment, the power switch 11 of the light-emitting unit 2a and the power switch 12 of the heater 13 are arranged in opposing positions across the axis O2, as shown in FIG. 16 . In this case, for example, the flashlight 1 and the heater 13 can be operated with one hand using the index finger and thumb. Therefore, by arranging the power switches 11 and 12 in opposing positions across the axis O2, as in this embodiment, the flashlight 1 is even easier to handle.

[0125] 16, reference numeral 2b denotes a heat sink, reference numeral 2c denotes a switch circuit unit of the light-emitting unit 2a connected to the power switch 11, and reference numeral 2d denotes a switch circuit unit of the heater 13 connected to the power switch 12.

[0126] In this embodiment, the tail 5 is rotatable in the circumferential direction around the axis O2 of the light-emitting device 2 relative to the body 4. This allows the user to move the mounting hole 74 to the optimal position desired.

[0127] In this embodiment, a connecting member 16 is disposed between the body 4 and the tail 5 of the light emitting device 2 for rotating the tail 5 relative to the body 4 in the circumferential direction around the axis O2.

[0128] Figure 17 shows an enlarged view of region R1 in Figure 16. In this embodiment, the connecting member 16 is a cylindrical member. In this embodiment, the connecting member 16 is fixed to the center body 4b of the body 4. In this embodiment, the tail 5 is attached to the outer peripheral surface of the connecting member 16 so as to be slidable in the circumferential direction about the axis O2. This allows the tail 5 to rotate in the circumferential direction about the axis O2 with respect to the body 4.

[0129] 18 shows an enlarged view of region R2 in FIG. 16. The head 3 is movable in the axial direction relative to the body 4. In this embodiment, the head 3 is slidably held in the center body 4b of the body 4 via an annular seal member 17. Examples of the seal member 17 include an O-ring made of rubber, elastomer, or resin. This allows the head 3 to slide forward and backward in the axial direction relative to the body 4. The focal region of the light emitted from the flashlight 1 can be changed as the head 3 moves forward and backward. Furthermore, the head 3 is rotatable in the circumferential direction around axis O2 relative to the center body 4b via the seal member 17.

[0130] In this embodiment, the tail 5 is rotatable in the circumferential direction about the axis O2 relative to the body 4 by sliding the tail 5 relative to the body 4 (connecting member 16). However, as in the case of the head 3, the tail 5 can be rotated in the circumferential direction about the axis O2 relative to the body 4b by, for example, interposing a sealing member such as an O-ring between the body 4 (e.g., connecting member 16 or center body 4b) and the tail 5. The tail 5 can also be rotated in the circumferential direction about the axis O2 relative to the body 4b by using a rotating means such as a gear.

[0131] The above is merely an exemplary embodiment of the present invention, and various modifications are possible within the scope of the claims. For example, while the flashlight 1 has a bracket attached to the tail 5 of the light-emitting device 2, the bracket can be attached to any part of the light-emitting device 2 other than the tail 5. Furthermore, the holding means can be omitted. Specifically, if the heater 13 is a film heater, the heater 13 can be brought into contact with the inner surface of the grip 4a by utilizing the restoring force of the film heater. In this case, the holding means can be omitted. The holder 100 is an example applicable to the flashlight 1. A holder applicable to the flashlight 1 preferably includes a holding portion 110 having a main body 111 with a notch 111d that guides the bracket neck 6b of the bracket 6 of the flashlight 1 and a stopper member 112 that can appropriately open the upper end opening of the notch 111d, and a plate-shaped portion 120 on which a belt B worn by the user can be placed between the holding portion 110.
