DETAILED DESCRIPTION OF THE INVENTION

[0012] The light emitting device 1 according to the embodiment of the present invention shown in Figures 1 and 2 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. Note that 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] In FIG. 1, reference numeral 15 denotes a switch for turning the power on and off, and reference numeral 17 denotes a push button switch for changing the light emission mode of the light emitter 3.

[0018] As shown in Fig. 2, the light emitting device 1 is configured to include a tip space forming material (top case) 19 and a contained body (e.g., decorative body) 21. The tip space forming material 19 is installed at the tip of the tip side portion 11 and forms a tip space (e.g., a closed space) 23 together with the tip side portion 11. For example, a plurality of contained bodies 21 are contained in the tip space 23, and each of them is capable of moving (moving or rotating) within the tip space 23.

[0019] The tip space forming member 19 is detachably attached to the tip side member 11 at the tip of the tip side member 11. That is, when the tip space forming member 19 is installed integrally with the tip side member 11, the tip space forming member 19 can be easily removed from the tip side member 11 with bare hands. Furthermore, when the tip space forming member 19 has been removed from the tip side member 11, the tip space forming member 19 can be easily installed integrally with the tip side member 11 with bare hands.

[0020] The light emitting device 1 is also configured to include an engaging member (top case support) 25. The engaging member 25 is integrally installed on a bottom wall portion (bottom wall portion of the tip side portion 11) 27 located at the tip of the tip side portion 11.

[0021] The tip space forming member 19 is detachably attached to the tip side portion 11 by engaging with the engaging member 25. The engaging member 25 is installed on the bottom wall portion 27 of the tip side portion 11 and protrudes from the bottom wall portion 27 of the tip side portion 11 to the side opposite to the base end portion 9 of the housing 5 (the tip side).

[0022] As shown in FIG. 3, the tip space forming member 19 is configured to include a short cylindrical side wall portion 29 and an upper wall portion 31 having a thickness similar to that of the side wall portion 29.

[0023] The upper wall portion 31 closes one opening of the side wall portion 29. The upper surface (outer surface) and lower surface (inner surface) of the upper wall portion 31 are spherical (the curved shape of a spherical crown). The upper wall portion 31 is provided on the side wall portion 29 in a manner that protrudes from one opening of the side wall portion 29. The outer diameter of the side wall portion 29 is approximately equal to the outer diameter of the cylindrical side wall portion 28 of the tip side portion 11. A female thread 33 is formed on the inner circumference of the side wall portion 29.

[0024] As shown in Figure 4, the engaging member 25 is configured to include a short, cylindrical side wall portion 35 and a disk-shaped bottom wall portion 37 with the same thickness as the side wall portion 35. The bottom wall portion 37 closes one opening of the side wall portion 35. The outer diameter of the bottom wall portion 37 is approximately equal to the outer diameter of the cylindrical side wall portion 28 of the tip end portion 11. The outer diameter of the side wall portion 35 is smaller than the outer diameter of the bottom wall portion 37. A male thread 39 is formed on the outer periphery of the side wall portion 35.

[0025] The bottom wall 37 is provided with a plurality of (for example, four) protrusions 41. The protrusions 41 are formed in a cylindrical shape with a small diameter, and protrude a predetermined height from the surface of the bottom wall 37 opposite the side wall 35.

[0026] The engaging member 25 is attached to the distal end portion 11 by a retaining member 43 (see FIG. 2). The retaining member 43 is formed in a disk shape. The outer diameter of the retaining member 43 is smaller than the inner diameter of the side wall portion 28 of the distal end portion 11. The retaining member 43 is provided with a plurality of holes 47 into which the plurality of protrusions 41 of the engaging member 25 are inserted, respectively.

[0027] The bottom wall 27 of the tip end portion 11 is provided with a plurality of through holes 45 through which the plurality of protrusions 41 of the engagement member 25 pass. The inner diameter of the through holes 45 is slightly larger than the outer diameter of the protrusions 41.

[0028] The tip space forming member 19, the engaging member 25, and the holding member 43 are integrally installed in the tip side portion 11. In this state, the tip space 23 is formed. The state in which the tip space forming member 19, the engaging member 25, and the holding member 43 are integrally installed in the tip side portion 11 is referred to as the tip space forming state.

[0029] In the tip space forming state, the central axis of the side wall portion 29 of the tip space forming member 19, the central axis of the side wall portion 35 of the engaging member 25, the central axis of the side wall portion 28 of the tip side portion 11, and the central axis of the holding member 43 are all aligned with one another. In the tip space forming state, the bottom wall portion 37 of the engaging member 25 is in contact with the bottom wall portion 27 of the tip side portion 11, and the holding member 43 is also in contact with the bottom wall portion 27 of the tip side portion 11.

[0030] In the tip space forming state, the protrusion 41 of the engaging member 25 passes through the through-hole 45 of the bottom wall 27 of the tip side portion 11, and the protrusion 41 of the engaging member 25 is fitted into the hole 47 of the holding member 43, for example, by an interference fit. As a result, the bottom wall 27 of the tip side portion 11 is sandwiched between the bottom wall 37 of the engaging member 25 and the holding member 43, and the tip side portion 11, the engaging member 25, and the holding member 43 are integrated.

[0031] In the tip space forming state, the female thread 33 of the tip space forming member 19 is threaded onto the male thread 39 of the engaging member 25 , and the tip space forming member 19 is integrally installed on the tip side portion 11 .

[0032] The tip space forming member 19, the engaging member 25, and the holding member 43 are each integrally molded and made of synthetic resin, and the base end portion 9 and the tip end portion 11 are also each integrally molded. The tip space forming member 19, the engaging member 25, the holding member 43, and the contained body 21 are transparent or translucent (including colored transparent and colored translucent), and are configured to transmit light emitted by the light emitter 3.

[0033] When the light emitter 3 in the light emitting device 1 emits light, the light emitted by the light emitter 3 passes through the holding member 43, the bottom wall portion 27 of the tip side portion 11, the engaging member 25, the contained body 21, and the tip space forming material 19, and emerges outside the light emitting device 1.

[0034] In the light emitting device 1, a tip space 23 is formed by the tip space forming material 19, and the contained object 21 is contained in the tip space 23. This not only allows the light emitting device 1 to emit light, but also makes sounds when the contained objects 21 collide with each other, for example, by shaking the light emitting device 1, thereby further enhancing the dramatic effect.

[0035] Furthermore, by shaking the light emitting device 1, the direction of travel of the light transmitted through the contained body 21 and the light reflected by the contained body 21 changes rapidly, further enhancing the dramatic effect.

[0036] Furthermore, in the light emitting device 1, the tip space forming member 19 is detachably provided in the tip side portion 11. This makes it easy to replace the contained body 21 in the tip space 23, and by changing the shape of the contained body 21, different presentation effects can be easily obtained.

[0037] Furthermore, in the light emitting device 1, the tip space forming member 19 is detachably attached to the tip side portion 11 of the light emitting device 1 by engaging with the engaging member 25. The inner surface of the tip space forming member 19 may be damaged by the object 21 housed in the tip space 23 hitting it. However, the tip side portion 11 of the light emitting device 1 can be used as is without changing the tip space forming member 19 and the tip space forming member 19 can be replaced with a new one.

[0038] As described above, the tip space forming material 19, the engaging member 25, the holding member 43, the contained body 21, and the bottom wall 27 are transparent or translucent (including colored transparent and colored translucent). Here, at least one of the tip space forming material 19, the engaging member 25, the holding member 43, and the contained body 21 (for example, all of the tip space forming material 19, the engaging member 25, the holding member 43, and the contained body 21) may be opaque so that the light emitted by the light-emitting body 3 does not pass through. Furthermore, the reflectance of the surface of the contained body 21 (the reflectance of the light emitted by the light-emitting body 3) may be higher than the reflectance of the surfaces of the tip space forming material 19, etc.

[0039] The base end portion 9, the tip end portion 11, the tip space forming member 19, the contained body 21, the engaging member 25, and the holding member 43 have such rigidity that they can be regarded as rigid bodies. Here, the rigidity of the contained body 21 may be lower than the rigidity of the base end portion 9, etc., in order to minimize or eliminate the sound of the contained body 21 hitting each other when the light emitting device 1 is held and shook by hand.

[0040] Furthermore, in the light emitting device 1, the tip space forming material 19 has a female thread 33 and the engaging member 25 has a male thread 39, but the tip space forming material 19 may have a male thread and the engaging member 25 may have a female thread.

[0041] Next, a light emitting device 1a according to a first modified example will be described with reference to Figures 5 to 7 and 22. The light emitting device 1a differs from the light emitting device 1 shown in Figures 1, 2, etc. in the manner in which the tip space forming material 19 engages with the engaging member 25, but is otherwise configured similarly to the light emitting device 1. Note that the contained body 21 is not shown in Figure 5, etc.

[0042] To explain further, instead of a female thread, protrusions (for example, a pair of protrusions) 49 are provided on the side wall 29 of the tip space forming member 19. Moreover, instead of a male thread, L-shaped notches (for example, a pair of notches; see FIG. 7) 51 are provided on the side wall 35 of the engaging member 25. The notches 51 penetrate the side wall 35 in the thickness direction of the tube (diameter direction of the tube).

[0043] The pair of protrusions 49 fit into the pair of cutouts 51, respectively, so that the tip space forming member 19 can be detachably attached to the engaging member 25. When the tip space forming member 19 is attached to the engaging member 25, the protrusions 49 are located at the innermost part of the cutouts 51, as shown in Figures 22(a) and (b). Here, as shown in Figure 22(c), a protrusion 53 may be provided in the cutout 51. The tip space forming member 19 may be made difficult to rotate with respect to the engaging member 25, so that the tip space forming member 19 is difficult to separate from the engaging member 25.

[0044] Next, a light emitting device according to a second modified example will be described with reference to Fig. 8. In the light emitting device according to the second modified example, the shape of the "L"-shaped notch 51 of the engaging member 25 is different from the "L"-shaped notch 51 of the light emitting device 1a according to the first modified example. In other respects, the light emitting device according to the second modified example is formed in the same manner as the light emitting device 1a according to the first modified example.

[0045] In the light-emitting device according to the second variant, the "L"-shaped notch 51 of the engaging member 25 is recessed outward from the inner surface of the side wall portion 35, but does not penetrate the side wall portion 35 in the thickness direction of the tube (diameter direction of the tube) but stops halfway.

[0046] Next, a light emitting device 1b according to a third modified example will be described with reference to Figures 9 to 11. In the light emitting device 1a according to the first modified example, a protrusion 49 is provided on the side wall portion 29 of the tip space forming member 19, and an "L"-shaped notch 51 is provided on the side wall portion 35 of the engaging member 25. In the light emitting device 1b according to the third modified example, an "L"-shaped notch 51 is provided on the side wall portion 29 of the tip space forming member 19, and a protrusion 49 is provided on the side wall portion 35 of the engaging member 25. In other respects, the light emitting device 1b is configured similarly to the light emitting device 1a.

[0047] Next, a light emitting device 1c according to a fourth modification will be described with reference to Figures 12 to 14. The light emitting device 1c differs from the light emitting device 1 shown in Figures 1, 2, etc. in the manner in which the tip space forming member 19 and the engaging member 25 are engaged. In other respects, the light emitting device 1c is configured similarly to the light emitting device 1.

[0048] Explaining further, an annular groove (recess) 55 is provided on the outer periphery of the side wall 29 of the tip space forming member 19, and a groove 57 is provided on the inner periphery of the side wall 35 of the engaging member 25. Then, as shown in Figure 12, when the tip space forming member 19 is installed in the engaging member 25, an O-ring 59, which is an annular elastic body (for example, a torus-shaped elastic body), fits into the groove 55 and the groove 57. In this way, the tip space forming member 19 is installed integrally with the engaging member 25.

[0049] 12, the side wall portion 29 of the tip space forming member 19 is located on the inside, and the side wall portion 35 of the engaging member 25 is located on the outside. However, the side wall portion 29 of the tip space forming member 19 may be located on the outside, and the side wall portion 35 of the engaging member 25 may be located on the inside.

[0050] Next, a light emitting device 1d according to a fifth modified example will be described with reference to Figures 15 and 16. The light emitting device 1d according to the fifth modified example differs from the light emitting device 1c according to the fourth modified example in that a large number of elastic folds 61 are used instead of the O-ring 59, but in other respects it is configured similarly to the light emitting device 1c.

[0051] The folds 61 protrude from the outer periphery of the side wall portion 29 of the tip space forming member 19. The folds 61 are arranged at predetermined small intervals from one another in the circumferential direction of the side wall portion 29. When the tip space forming member 19 is installed in the engaging member 25, the folds 61 are slightly elastically deformed.

[0052] 15, the side wall portion 29 of the tip space forming member 19 is located on the inside, and the side wall portion 35 of the engaging member 25 is located on the outside. However, the side wall portion 29 of the tip space forming member 19 may be located on the outside, and the side wall portion 35 of the engaging member 25 may be located on the inside. In this case, the pleats 61 are provided, for example, on the inner side wall portion 35.

[0053] Next, a light emitting device 1e according to a sixth modified example will be described with reference to Fig. 17. The light emitting device 1e according to the sixth modified example differs from the light emitting device 1 in that the engaging member 25 is directly installed on the tip end portion 11 without using a holding member 43, but is otherwise configured similarly to the light emitting device 1.

[0054] A snap fit method is used to attach the engaging member 25 to the tip end portion 11. That is, the bottom wall portion 37 of the engaging member 25 is provided with a locking projection 65 having a groove 63 instead of the protrusion 41. The groove 63 is provided to allow the locking projection 65 to easily deform elastically.

[0055] When the engaging member 25 is in the process of being installed in the tip end portion 11, the tip end of the locking projection 65 enters the through hole 45 provided in the bottom wall portion 27 of the tip end portion 11. This causes the locking projection 65 to elastically deform so as to reduce the width dimension of the groove 63.

[0056] When the engagement member 25 has been installed in the distal end portion 11, the locking projection 65 returns to its original position, and the base end of the locking projection 65 passes through the through-hole 45. In addition, the bottom wall portion 27 of the distal end portion 11 is sandwiched between the tip end of the locking projection 65 and the bottom wall portion 37 of the engagement member 25. In this way, the engagement member 25 is installed integrally with the distal end portion 11.

[0057] Next, a light emitting device 1f according to a seventh modified example will be described with reference to Fig. 18. The light emitting device 1f according to the seventh modified example also differs from the light emitting device 1 in that the engaging member 25 is directly installed on the tip side portion 11 without using a holding member 43, but is otherwise configured similarly to the light emitting device 1.

[0058] In the light emitting device 1f according to the seventh modification, a protrusion 41 provided on the bottom wall portion 37 of the engaging member 25 is fitted into a through-hole 45 provided on the bottom wall portion 27 of the tip side portion 11 in an interference fit manner, so that the engaging member 25 is integrally installed on the tip side portion 11. Note that when the engaging member 25 is installed on the tip side portion 11, the protrusion 41 does not protrude, for example, from the through-hole 45 of the bottom wall portion 27 downward as shown in FIG.

[0059] Next, a light emitting device 1g according to an eighth modified example will be described with reference to Fig. 19. The light emitting device 1g according to the eighth modified example also differs from the light emitting device 1 in that the engaging member 25 is installed in the tip side portion 11 without using a holding member 43, but is otherwise configured similarly to the light emitting device 1.

[0060] In a light emitting device 1g according to an eighth modification, the engaging member 25 is integrally attached to the tip side portion 11 by using an adhesive (for example, a transparent or semi-transparent adhesive) without using the protrusion 41 or the through-hole 45. Note that instead of or in addition to using an adhesive, the engaging member 25 may be integrally attached to the tip side portion 11 by crimping a part of the tip side portion 11 and a part of the engaging member 25 together.

[0061] Next, a light emitting device 1h according to a ninth modified example will be described with reference to Fig. 20. The light emitting device 1h according to the ninth modified example differs from the light emitting device 1 in that the tip space forming member 19 is installed in the tip side portion 11 without using a holding member 43 or an engaging member 25, but is otherwise configured in the same way as the light emitting device 1.

[0062] That is, in the light emitting device 1h, a cylindrical portion 67 protrudes from the bottom wall portion 27 located at the tip of the tip side portion 11. The tip side portion 11 and the cylindrical portion 67 are formed by integral molding. The tip space forming member 19 is configured to be directly installed in the cylindrical portion 67.

[0063] To explain further, a cylindrical portion 67 protrudes from the tip of the tip side portion 11, and a male thread 69 is formed on the outer periphery of the cylindrical portion 67. A female thread 33 is formed on the inner periphery of the side wall portion 29 of the tip space forming member 19. When the tip space forming member 19 is installed in the tip side portion 11, the male thread 69 of the cylindrical portion 67 is threadedly engaged with the female thread 33 of the tip space forming member 19.

[0064] In the light emitting device 1h, the tip space forming member 19 is configured to be installed in the cylindrical portion 67, so the configuration of the light emitting device 1h is simplified.

[0065] Next, a light emitting device 1i according to a tenth modified example will be described with reference to Fig. 21. The light emitting device 1i according to the tenth modified example differs from the light emitting device 1h shown in Fig. 20 in that a male thread 71 is formed on the outer periphery of the side wall portion 29 of the tip space forming member 19, and a female thread 73 is provided on the inner periphery of the cylindrical portion 67, but in other respects it is configured similarly to the light emitting device 1h.

[0066] The light emitting devices 1h and 1i shown in Figures 20 and 21 may be modified as follows. The cylindrical portion 67, the side wall 27 of the tip portion 11, and a portion of the side wall 27 of the tip portion 11 near the bottom wall 28 are defined as a first tip portion constituent member. The remaining portion of the tip portion 11 is defined as a second tip portion constituent member. The first tip portion constituent member is integrally molded and is separate from the second tip portion constituent member, which is also integrally molded and separate from the first tip portion constituent member. For example, a screw may be provided in the portion of the side wall 27 of the first tip portion constituent member near the bottom wall 28, and a screw may also be provided in the tip portion of the second tip portion constituent member (the end portion of the first tip portion constituent member). The screws may then be threaded together to allow the first tip portion constituent member to be detachably attached to the second tip portion constituent member.

[0067] 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]
