[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a luminescent ball having a luminescent property.

[0002]

[Prior art]

 This type of luminous ball can be used for baseball, tennis, soccer, rugby, volleyball, and other ball games without lighting equipment or with little lighting, as nighttime sports population is increasing due to diversification of working hours. Make it possible with equipment. Since ball games using light-emitting balls require new skills, they have the potential to develop into ball games in new fields. Furthermore, a viewer of a ball game using a light-emitting ball can have a different sense of speed and aesthetic sense than in the daytime. In addition, the luminescent ball can be used as an appreciation object for an interior or for a night-time entertainment.

As a conventional light emitting ball, for example, Japanese Utility Model Application Laid-Open No. 63-85263 discloses a light emitting ball as shown in FIG. The luminescent ball has a transparent and tough outer skin, has a structure in which a ball is filled with a luminescent liquid, and a capsule containing a luminescent excitation liquid is contained therein. Before use, a strong impact is applied to the ball to break the capsule inside, and the ball emits light by mixing the luminescence liquid and the luminescence excitation liquid. Japanese Patent Laid-Open Publication No. 57-107171 discloses a light emitting ball as shown in FIG. This luminescent ball is obtained by applying a luminescent member such as a luminous paint to the outer surface of the ball.

[0004]

[Problems to be solved by the invention]

 However, since the luminescent ball shown in FIG. 5 is filled with the luminescent liquid inside the ball, the weight becomes heavy, and the motion characteristics of the ball are significantly different from those of the existing ball. This becomes more pronounced as the ball gets larger. Therefore, it may be difficult to play a ball game as in the case of using an existing ball. In addition, if the capsule containing the luminescence excitation liquid is formed from a resin or the like, it is difficult and inconvenient to destroy the capsule before use, and if a capsule made of glass is used to easily and surely destroy the capsule, ball games will be difficult. It is extremely dangerous in doing so. Further, the light-emitting ball shown in FIG. 6 uses a light-emitting member such as a luminous paint, so that the light amount is small and the light cannot be emitted in a non-light space, so that the use range of the ball is limited. I will.

[0005] The present invention has been made in view of such problems of the prior art, and an object of the invention is to make the light emission more secure and reliable and to obtain the same motion characteristics as existing balls. It is intended to provide an inexpensive light emitting ball that can be used.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the light emitting ball according to the first invention has a plurality of joints so as to form a sealed space between a translucent and strong spherical outer skin and the outer skin. And a luminous liquid filled in a sealed space between the inner skin and the outer skin, and an injection that is detachably attached to the outer skin. And a luminescence excitation liquid contained in the injector. That is, since the light emitting device is composed of the inner and outer coatings and the luminescent liquid is filled between the two films, the entire surface of the spherical ball can be uniformly illuminated with an appropriate amount of the luminescent liquid. By attaching an injector filled with the luminescence excitation liquid to the outer skin in advance, the luminescence liquid and the luminescence excitation liquid can be mixed securely and safely without using a syringe with a needle or a glass capsule. Can be. After pushing the injector to inject the luminescence excitation liquid into the sealed space and mixing it with the luminescence liquid to emit light, the injector is detached from the outer skin.

The light-emitting ball according to the second invention has a tough spherical outer skin having a light-transmitting and hollow inside, a sponge-like coating layer formed on the inner surface of the outer skin, and a coating layer. It comprises a luminescent liquid that has penetrated into the container, an injector detachably attached to the outer skin, and a luminescence excitation liquid contained in the injector. That is, since the luminescent liquid penetrates into the coating layer on the inner surface of the outer skin, the entire surface of the spherical ball can be uniformly illuminated with an appropriate amount of the luminescent liquid. By attaching the syringe filled with the luminescence excitation liquid to the outer skin in advance, it is possible to mix the luminescence liquid and the luminescence excitation liquid securely and safely without using an injector with a needle or a glass capsule. it can. After pushing the injector to inject the luminescence excitation liquid into the hollow part of the outer skin, the ball is shaken to mix the luminescence excitation liquid with the luminescence liquid penetrating the coating layer to emit light. The injector is detached from the skin and the ball is used.

[0008] A luminescent ball according to a third aspect of the present invention has a tough spherical outer skin having a light-transmitting and hollow inside, a sponge-like coating layer formed on the inner surface of the outer skin, and a coating layer. A core tube connecting two points on the inner surface of the outer skin and having a fragile portion, and a luminescence excitation liquid contained in the core tube. That is, since the luminescent liquid penetrates into the coating layer on the inner surface of the outer skin, the entire surface of the spherical ball can be uniformly illuminated with an appropriate amount of the luminescent liquid. By filling the core tube formed so as to connect the two points on the inner surface of the outer skin with the luminescence excitation liquid, the core tube is compressed and buckled to break the fragile portion, thereby discharging the luminescence excitation liquid. It can be mixed with the luminescent liquid reliably and safely. Since the core tube is in contact with the inner surface of the outer skin, it becomes possible to easily fill the luminescence excitation liquid into the core tube during manufacturing. After applying an external force to the outer skin to break the fragile portion of the core tube, the ball is shaken to mix the luminescence excitation liquid with the luminescence liquid penetrating the coating layer to emit light.

[0009] Since the light emitting balls according to the first to third inventions are hollow inside, they have the same motion characteristics and weight as existing balls.
