[0016] The light emitting device 1 according to the embodiment of the present invention shown in Figs. 1 to 3 is intended to be held by spectators at a concert venue, for example, and is configured to include a light emitter 3, a housing 5, and a control unit 7, as shown in Figs. 2 and 3. The light emitting device 1 may also be used at sporting event venues, theme parks, and other venues other than concert venues. That is, the light emitting device 1 may be used by spectators at sporting event venues to cheer on athletes, or by cast members and guests at theme parks to enhance the atmosphere and enjoy the event.

[0017] The housing 5 is configured to include a base end portion (gripping portion) 9 and a tip end portion (light emitting portion) 11. The base end portion 9 is formed, for example, in a cylindrical shape with a bottom, from an opaque synthetic resin that does not transmit light (visible light). The tip end portion 11 is formed, for example, in a cylindrical shape with a bottom, from a transparent or translucent (including colored transparent) synthetic resin that transmits light (visible light). The tip end portion 11 is integrally installed on the base end portion 9 such that the opening of the base end portion 9 mates with the opening of the tip end portion 11.

[0018] The exterior shape of the housing 5 is, for example, a columnar shape such as a long, thin cylinder. One side of the longitudinal direction of the housing 5 is a base end side portion 9, and the other side of the longitudinal direction of the housing 5 is a tip end side portion 11. A closed space is formed inside the housing 5. The shape of the closed space is a long, thin columnar shape (for example, a cylinder) that is slightly smaller than the exterior shape of the housing 5.

[0019] A battery 13 is accommodated and installed inside the base end portion 9 within the closed space of the housing 5. The light emitter 3 is configured to include a red LED, a green LED, and a blue LED. A control unit 7 is also provided inside the base end portion 9 within the closed space of the housing 5. The light emitter 3 is provided near the opening of the base end portion 9.

[0020] The control unit 7 receives power from the battery 13 and causes the light emitter 3 to emit light in various ways. The light emitter 3 emits light (visible light) toward the inside of the tip end portion 11. When the housing 5 with the light emitter 3 emitting light is viewed from the outside of the housing 5, the tip end portion 11 emits light.

[0021] 2 and 3, reference numeral 21 denotes a switch for turning the power on and off, and reference numeral 23 denotes a push button switch for changing the light emission mode of the light emitter 3. Similarly to the light emitter 1, light emitters 1a to 1f according to modified examples described below are also configured with a light emitter 3, a housing 5, a control unit 7, etc., and are intended to be used in concert venues and the like.

[0022] The light emitting device 1 is provided with a hook (hook; for example, a finger hook) 15. The hook 15 is provided on the base end portion 9 outside the base end portion 9. The hook 15 is designed so that when a person holds the base end portion 9 in their hand, part of their hand can be hooked onto it.

[0023] That is, when a person holds the base end portion 9 in his / her hand, the person can hook a part of his / her hand (for example, a part of his / her finger) on the hook portion 15. Furthermore, the hook portion 15 is provided to prevent the light emitting device 1 from coming off the hand and dropping even if the person swings the light emitting device 1 around while holding the base end portion 9 in his / her hand.

[0024] The hook 15 is configured to include a ring-shaped portion 17 into which a person's fingers (one or more fingers) fit when the person grips the base end portion 9. More specifically, the ring-shaped portion 17 of the hook 15 is formed by a ring-shaped portion component 19 and the base end portion 9.

[0025] The annular portion constituent member 19 extends longitudinally along the longitudinal direction of the base end portion 9 (the direction in which the central axis of the tube of the base end portion 9 extends). Both longitudinal ends of the annular portion constituent member 19 are joined to the base end portion 9.

[0026] The annular portion constituent member 19 is configured to be in an annular portion forming state in which the longitudinal intermediate portion separates from the base end portion 9 to form the annular portion 17 (see FIG. 3). Alternatively, the annular portion constituent member 19 is configured to be in an annular portion non-forming state in which it contacts the base end portion 9 over the entire longitudinal length (see FIG. 2).

[0027] In the state where the annular portion is not formed as shown in Fig. 2, the annular portion constituent member 19 protrudes only slightly from the base-end portion 9. As a result, in the state where the annular portion is not formed, even though the annular portion constituent member 19 is provided, it appears that almost no protrusion is formed by the annular portion constituent member 19 in the base-end portion 9. Furthermore, in the state where the annular portion is formed as shown in Fig. 3, the annular portion constituent member 19 clearly protrudes from the base-end portion 9.

[0028] Although not shown, a recess (recess into which the annular portion constituent material 19 fits) may be provided in the base-end side portion 9. Then, in a state where the annular portion is not formed, the annular portion constituent material 19 may fit into the recess, so that the annular portion constituent material 19 does not protrude from the base-end side portion 9.

[0029] That is, in the state where the annular portion is not formed, the annular portion constituent material 19 may be configured so that no step is formed at the boundary between the surface of the annular portion constituent material 19 and the surface of the base-end portion 9. At the boundary, the surface of the annular portion constituent material 19 and the surface of the base-end portion 9 are smoothly connected.

[0030] The annular portion constituent member 19 is made of an elastic body (such as rubber) (especially elastic in the longitudinal direction) and is formed in a strip shape (a thin, elongated rectangle) with a predetermined width and thickness. The annular portion constituent member 19 has a length dimension value > width dimension value > thickness dimension value. The annular portion constituent member 19 is installed in the base-end portion 9 so that the thickness direction is the radial direction of the base-end portion 9 and the width direction is the circumferential direction of the base-end portion 9.

[0031] In the annular portion forming state, the annular portion forming member 19 is configured to be in the annular portion forming state (see FIG. 3) by elastically deforming and stretching mainly in the longitudinal direction when subjected to a force from a hand, for example.

[0032] Furthermore, the annular portion component 10 is configured so that when no external force other than gravity is applied, the annular portion component 19 contacts the base end portion 9 over its entire length, resulting in an annular portion not being formed (see Figure 2).

[0033] For example, even when the annular portion is not formed, a tensile stress of a predetermined magnitude is generated in the annular portion component 19 in the longitudinal direction, and the annular portion component 19 contacts the base end portion 9 with a biasing force.

[0034] The light emitting device 1 is provided with a hook 15 on which part of a person's hand can hook when the person holds the base end portion 9 in their hand. The hook 15 is provided on the base end portion 9 of the housing 5. This prevents the light emitting device 1 from easily coming off the hand, even when the light emitting device 1 is held in the hand and swung around at a concert venue or the like. This prevents the light emitting device 1 from falling out of the hand, and prevents damage to the light emitting device 1.

[0035] Furthermore, the light emitting device 1 is configured such that the hook portion 15 has a ring-shaped portion 17 inside which a finger can be inserted, so that the light emitting device 1 can be more reliably prevented from slipping off the hand.

[0036] Furthermore, in the light emitting device 1, the annular portion 17 of the hook portion 15 is configured to be composed of an annular portion component 19 and a base end portion 9. The annular portion component 19 extends long along the longitudinal direction of the base end portion 9, and both longitudinal ends are joined to the base end portion 9. This allows the annular portion 17 of the hook portion 15 to be formed with a simple configuration.

[0037] Furthermore, since the annular portion component 19 extends longitudinally along the base end portion 9, when the base end portion 9 is grasped with the hand, four fingers from the index finger to the little finger can be placed inside the annular portion 17, and the light-emitting device 1 can be held in a stable state.

[0038] Furthermore, the light emitting device 1 is configured so that the annular portion constituent member 19 can be in an annular portion forming state or an annular portion non-forming state. In the annular portion forming state, the annular portion constituent member 19 is in contact with the base end side portion 9 over the entire longitudinal length. As a result, in the annular portion non-forming state, the annular portion constituent member 19 protrudes less from the base end side portion 9, and when the hook portion 15 is not in use, the annular portion constituent member 19 hardly gets in the way.

[0039] Furthermore, the light emitting device 1 is configured so that the annular portion forming state occurs when the annular portion forming member 19 elastically deforms and stretches mainly in the longitudinal direction. Also, the annular portion non-forming state occurs when the annular portion forming member 19 contacts the base end portion 9 over its entire length. Even in the annular portion non-forming state, a tensile stress of a predetermined magnitude is generated in the annular portion forming member 19 in the longitudinal direction, and the annular portion forming member 19 contacts the base end portion 9 with a biasing force.

[0040] This eliminates rattle of the annular portion constituent member 19 in the annular portion non-formed state relative to the base end portion 9. In addition, in the annular portion formed state, the annular portion constituent member 19 has elasticity and contacts the hand with a certain degree of biasing force, making the light emitting device 1 easier to hold.

[0041] Next, a light emitting device 1a according to a first modified example will be described with reference to Figures 4 to 6. In the light emitting device 1a, the annular portion constituent material 19 is made of a material with a predetermined elasticity, such as leather (including synthetic leather) or synthetic resin. The annular portion constituent material 19 is formed in a strip shape (a thin, elongated rectangle) with a predetermined width and thickness. The annular portion constituent material 19 also has the following relationship: "length dimension value > width dimension value > thickness dimension value."

[0042] The annular portion constituent member 19 is installed in the base-end portion 9 so that its thickness direction is the radial direction of the base-end portion 9 and its width direction is the circumferential direction of the base-end portion 9. The annular portion constituent member 19 is designed to be easily deformed by a rotation moment about an axis extending in the width direction. That is, it is designed to be easily deformed from the straight shape shown in Fig. 5 to the curved shape shown in Fig. 6. Furthermore, the annular portion constituent member 19 is difficult to deform by a rotation moment about an axis extending in the thickness direction and a rotation moment about an axis extending in the length direction.

[0043] One longitudinal end of the annular portion constituent member 19 (the end on the tip end portion 11 side) is joined to the base end portion 9. The other longitudinal end of the annular portion constituent member 19 is provided with a through-hole 25 (an oval through-hole that penetrates the annular portion constituent member 19 in its thickness direction) that extends a predetermined length in the longitudinal direction of the annular portion constituent member 19. The through-hole 25 is located in the center of the annular portion constituent member 19 in the width direction.

[0044] An annular portion component support protrusion 27 is provided in a portion of the base end portion 9 that is distant from the tip end portion 11 in the longitudinal direction. The annular portion component support protrusion 27 protrudes from the base end portion 9 and passes through the through hole 25 of the annular portion component 19 to support the end of the annular portion component 19 in the longitudinal direction.

[0045] More specifically, the annular portion component support projection 27 is configured to include a small-diameter disk-shaped portion 43 and a large-diameter disk-shaped portion 45. The small-diameter disk-shaped portion 43 and the large-diameter disk-shaped portion 45 overlap each other in the thickness direction. The central axis of the small-diameter disk-shaped portion 43 and the central axis of the large-diameter disk-shaped portion 45 coincide with each other. The thickness dimension of the small-diameter disk-shaped portion 43 and the thickness dimension of the large-diameter disk-shaped portion 45 are approximately equal to the thickness dimension of the annular portion component 19. The diameter dimension of the small-diameter disk-shaped portion 43 is approximately equal to the width dimension of the through-hole 25, and the diameter dimension of the large-diameter disk-shaped portion 45 is approximately equal to the width dimension of the annular portion component 19. The thickness direction of the disk-shaped portions 43, 45 is the radial direction of the base-end portion 9.

[0046] In the annular portion component support projection 27, a small-diameter disk-shaped portion 43 protrudes directly from the base-end portion 9 and passes through the through-hole 25. The portion of the annular portion component 19 at the through-hole 25 (the portions on both sides of the through-hole 25) is sandwiched between the base-end portion 9 and the large-diameter disk-shaped portion 45.

[0047] As a result, the other longitudinal end of the annular portion constituent member 19 supported by the annular portion constituent member support projection 27 moves only relative to the base end portion 9 in the longitudinal direction of the base end portion 9.

[0048] In the light emitting device 1a, as shown in Figure 5, the other end of the annular portion component 19 moves in the longitudinal direction relative to the base end portion 9, so that the annular portion component 19 comes into contact with the base end portion 9 over its entire length, resulting in no annular portion being formed.

[0049] Furthermore, in the light emitting device 1a, as shown in Figure 6, movement of the other longitudinal end of the annular portion component 19 relative to the base end portion 9 causes the middle portion of the annular portion component 19 to bend away from the base end portion 9, thereby forming an annular portion.

[0050] That is, the light emitting device 1a is configured so that the movement of the other longitudinal end of the annular portion constituent member 19 relative to the base end portion 9 causes the annular portion constituent member 19 to assume a non-annular portion forming state or a annular portion forming state.

[0051] This allows the annular portion constituent member 19 to be in a non-annular portion formed state or a annular portion formed state with a simple configuration. Furthermore, when the light emitting device 1a is held in the hand in the annular portion formed state, the annular portion constituent member 19 comes into contact with the hand without generating any substantial biasing force, so that the annular portion constituent member 19 does not feel like it is squeezing the hand.

[0052] Next, a light emitting device 1b according to a second modified example will be described with reference to Figures 7 to 9. In the light emitting device 1b, the annular portion 17 of the hook portion 15 is configured to include an annular portion component 19. The annular portion component 19 is formed in an annular shape from an elastic body such as rubber.

[0053] The annular portion component 19 is formed into a ring shape by connecting both ends of a strip-shaped (long, rectangular, thin plate-shaped) member (length dimension value > width dimension value > thickness dimension value) with a predetermined width and thickness.

[0054] The annular portion constituent member 19 is provided, for example, at a location on the distal portion 11 side of the proximal portion 9, so that the circumferential direction of the ring is the circumferential direction of the proximal portion 9. The thickness direction of the annular portion constituent member 19 provided at the proximal portion 9 is the radial direction of the proximal portion 9, and the width direction is the longitudinal direction of the proximal portion 9.

[0055] A portion of the annular portion constituent member 19 in the circumferential direction of the ring (for example, a portion extending over approximately half the circumference) is elastically deformed and stretched mainly in the circumferential direction of the ring when subjected to, for example, a force from a hand. As a result, as shown in Figures 8 and 9, the portion of the annular portion constituent member 19 in the circumferential direction of the ring separates from the base-end portion 9. This results in an annular portion formed state in which the annular portion 17 is formed.

[0056] 9, the annular portion 17 is formed by the portion of the annular portion constituent member 19 indicated by the two-dot chain line 19A. In the annular portion formed state shown in FIG. 8, the other portion of the annular portion constituent member 19 in the circumferential direction of the ring (the remaining portion spanning approximately half the circumference that does not elastically deform) is provided integrally with the base-end portion 9.

[0057] As shown in Figs. 7 and 9, the annular portion forming member 19 is in contact with the base end portion 9 over the entire circumferential length of the ring, so that no annular portion is formed.

[0058] The annular portion constituent member 19 is configured to contact the base-end portion 9 over its entire circumferential length when no external force other than gravity is applied, and to be in a state where no annular portion is formed. In the state where no annular portion is formed, a tensile stress of a predetermined magnitude is generated in the annular portion constituent member 19 in the circumferential direction of the ring, and the annular portion constituent member 19 contacts the base-end portion 9 with a biasing force.

[0059] In the state where the annular portion is not formed, the annular portion constituent material 19 protrudes only slightly from the base-end portion. As a result, in the state where the annular portion is not formed, even though the annular portion constituent material 19 is provided, it appears that almost no protrusion is formed by the annular portion constituent material 19 in the base-end portion 9. In addition, in the state where the annular portion is formed, the annular portion constituent material 10 clearly protrudes from the base-end portion 9.

[0060] In the light emitting device 1b, the annular portion constituent member 19 is provided on the base end portion 9 so that the circumferential direction of the ring is the circumferential direction of the base end portion. A part of the circumferential direction of the ring of the annular portion constituent member 19 is configured to elastically deform into an annular portion forming state. Also, the entire circumferential length of the ring of the annular portion constituent member 19 is configured to be in an annular portion non-forming state in contact with the base end portion 9.

[0061] This allows the annular portion component 19 to be installed at only a small portion of the base end portion 9 in the longitudinal direction, and when holding the light emitting device 1b in the hand, it is possible to grip the base end portion 9 without touching the annular portion component 19. Furthermore, by providing the annular portion component 19 at a location near the tip end portion 11 of the base end portion 9, it is possible to insert the index finger or first finger into the annular portion 17 when holding the base end portion 9 in the hand. Thus, the light emitting device 1b can be held in the hand in a manner different from that of the light emitting devices 1 and 1a.

[0062] As in the case of the light emitting device 1, a recess (recess into which the annular portion constituent material 19 fits) may be provided in the base end side portion 9. Also, even when the annular portion constituent material 19 is not elastically deformed, a part of the circumferential portion of the annular portion constituent material 19 may be separated from the base end side portion 9 so that a state in which the annular portion is not formed cannot be achieved.

[0063] Next, a light emitting device 1c according to a third modification will be described with reference to Figures 10 to 12. In the light emitting device 1c, the hook 15 is configured to include a hook main body 29 and a bellows 31.

[0064] The hook body 29 extends longitudinally along the longitudinal direction of the base end portion 9 (the direction in which the central axis of the tube of the base end portion 9 extends). One end of the bellows 31 in the extension / contraction direction is joined to the base end portion 9, and the other end in the extension / contraction direction is joined to the hook body 29 at an intermediate portion (for example, the center portion) of the hook body 29 in the longitudinal direction.

[0065] 12, when the bellows 31 is extended and the light emitting device 1c is held by gripping the base end portion 9 of the light emitting device 1c with the hand, the fingers of the hand can be inserted between the base end portion 9 and the hook main body 29. Then, a part of the person's hand (for example, a part of the person's finger) can be hooked on the hook main body 29.

[0066] Next, a fourth modified example of light emitting device 1d will be described with reference to Fig. 13. Light emitting device 1d differs from light emitting device 1c in that a recess 33 recessed from the surface of base end portion 9 toward the center of base end portion 9 is provided in base end portion 9, but in other respects light emitting device 1d is configured similarly to light emitting device 1c.

[0067] The light emitting device 1d is configured so that the bellows 31 and the hook body 29 are housed in the recess 33 when the bellows 31 is fully contracted.

[0068] Furthermore, a locking portion is provided at the base end portion 9, and a locked portion is provided at the hook body 29, and the locked portion is locked to the locking portion, thereby maintaining the bellows 31 and the hook body 29 housed within the recess 33. In this case, by applying force with the fingers to the hook body 29, the locked portion can be easily released from its locked state. For example, a magnet 35 can be used as the locked portion or the locking portion.

[0069] 13, the gap indicated by reference numeral 37 is where a finger is inserted to release the locked portion from the locking portion. By inserting a finger into gap 37, hook portion main body 29 can be easily pulled out.

[0070] In addition, in the embodiment shown in FIG. 3, the bellows 31 and the hook body 29 are housed in the recess 33, but a recess that houses only the bellows 31 may be provided.

[0071] In the light emitting device 1d, the hook 15 is configured to include a hook main body 29 and a bellows 31. By contracting the bellows 31, it is possible to minimize the protrusion of the bellows 31 and the hook main body 29 from the base end portion 9. Furthermore, when the bellows 31 is extended and the base end portion 9 is gripped with the hand, the backs of the fingers come into contact with the hook main body 29. This prevents the light emitting device 1c from dropping from the hand.

[0072] 12 and 13, the index finger and middle finger can be inserted between the base end portion 9 and the hook main body 29 on the upper side of the bellows 31. The ring finger and little finger can be inserted between the base end portion 9 and the hook main body 29 on the lower side of the bellows 31. This allows the light emitting devices 1c and 1d to be held in the hand in a natural manner.

[0073] Next, a light emitting device 1e according to a fifth modification will be described with reference to Fig. 14. In the light emitting device 1e, the hook 15 is configured to include a hook main body 29, a first bellows 31A, and a second bellows 31B. The hook main body 29 extends long along the longitudinal direction of the base end portion 9 (the extension direction of the central axis of the tube of the base end portion 9).

[0074] The first bellows 31A has one end in the extension / contraction direction joined to one longitudinal end of the base end portion 9, and the other end in the extension / contraction direction joined to one longitudinal end of the hook portion main body portion 29.

[0075] The second bellows 31B has one end in the extension / contraction direction joined to the other longitudinal end of the base end portion 9, and the other end in the extension / contraction direction joined to the other longitudinal end of the hook portion main body portion 29.

[0076] When the bellows 31A, 31B are extended, the base end portion 9, the pair of bellows 31A, 31B, and the hook body 29 form the annular portion 17. Note that the light emitting device 1e may be provided with a recess, a locked portion, and a locking portion, similar to the light emitting device 1d.

[0077] In the light emitting device 1e, when the first bellows 31A and the second bellows 31B are extended, the base end portion 9, the pair of bellows 31A and 31B, and the hook body 29 form the annular portion 17. This allows the light emitting device 1e to be held stably by hand.

[0078] Next, a sixth modified example of a light emitting device 1f will be described with reference to Fig. 15. The hook portion 15 of the light emitting device 1f is configured to include a ring-shaped member 39 and a string-like member 41. The ring-shaped member 39 is designed to allow, for example, one of the fingers of a hand to pass through. The string-like member 41 connects the ring-shaped member 39 to the base-end portion 9.

[0079] In the light emitting device 1f, the hook part 15 is configured to include a ring-shaped member 39 and a string-like member 41 connecting the ring-shaped member 39 to the base end part 9. This allows the light emitting device 1f to be held in a stable state by hand without having to directly attach the ring-shaped part component 19 or the hook part main body 29 to the base end part 9.

[0080] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
