Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to tennis rackets and balls, baseball bats and balls, table tennis balls and the like.
BACKGROUND OF THE INVENTION The present invention relates to improvement of various sporting goods, and more particularly to sporting goods which emit illumination light with improved visibility and fashionability.

[0002]

2. Description of the Related Art Conventionally, various sporting goods, from shape, size to color, are determined and regulated by each sport. Among them, the acceptance of large golf balls and colored judo wear indicates that changes in competitors' demands for the regulation with the times will also change the conventional rules.

[0003]

In recent years, the number of sports which compete under artificial light has increased, and in order to improve the visibility, there is a case where a light reflecting parting line such as a line indicating a competition area is used. However, there is no direct use of sports equipment having a structure in which a part thereof emits light.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and illuminates various sporting goods such as baseball bats and balls, tennis rackets and balls, and table tennis balls, and a part of the goods. It is an object of the present invention to provide a new sporting goods which has not only improved visibility of a tool but also improved fashionability in sports that appeal to the sight.

[0005]

SUMMARY OF THE INVENTION A sporting goods that emits illuminated light according to the present invention is at least a part of various sporting goods such as tennis rackets and balls, baseball bats and balls, and table tennis balls. The gist of the invention is that the surface of the part is coated with an illumination light-emitting material or an illumination reflection material that emits illumination bright light by natural light or artificial light, or is formed of the material.

The illumination light emitting material can be applied to a gut stretched on a hitting surface such as a racket for tennis or badminton. The illumination light-emitting material is a member obtained by kneading an ultraviolet-absorbing light-emitting material, and the kneaded material can be used as a part of components of a product. Further, the illumination reflecting material can be implemented by attaching a holographic sheet to the surface of the article.

Here, the “illuminated bright light” referred to in the present invention will be described. What is illumination shine?
It refers to the formation of light shadows that emit light or reflect light so that the shape of the article is clearly visible even in dark areas, and sports equipment that emits illuminated light refers to equipment used in sports having such light shadows. .

Material that illuminates the illumination (illumination illuminant) [Reflective light system material] Retroreflective material A structural material having a minute diffusely reflecting mirror surface on its surface, which receives light and diffuses the light flux at a wide angle. Has properties. Polarizing reflector When reflecting a light beam, it has a property of shifting the wavelength cycle by 180 degrees, and forms an interference fringe of light when irradiated with the light beam. Holography Reflects the luminous flux that is split by receiving irradiation light. The reflected light forms irregular reflection, and an interference light image having a different color tone is obtained depending on the viewing position. [Phosphorescent material] Fluorescent substance Stimulates a fluorescent substance under irradiation of light to emit fluorescent light. E. FIG. L. (Electroluminescence) Visible light is emitted upon irradiation with an invisible light beam such as ultraviolet light. The E.C. L. Can be set to various colors by mixing with a pigment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The principle of a sporting goods emitting illumination light according to the present invention will be described below with reference to FIGS. FIG. 1 (a) shows a light-reflecting material, and a light-reflecting structure 2
And irregularly reflects the incident light beam L1 (reflected light beam L2). This reflection structure 2 is shown in FIG.
As shown in FIG. 7, as a structure different from the sports equipment body 1, a structure in which a retroreflective functional material such as a light reflection tape 3 is adhered may be employed.

FIG. 2 shows a luminous material, in which a luminous structure 4 is integrated with the surface of the sports equipment body 1 and the luminous material is excited by an incident light beam L1 to cause the luminous structure 4 to emit light. It was made. This phosphorescent material 4 is made of fluorescent or E. coli. L. Has been put into practical use,
Visible light in fluorescence; L. In this case, light emission L3 is obtained using ultraviolet light as the incident light beam L1. The luminous structure 4 can be formed as the sporting goods body 1 itself, for example, a gut of a tennis racket.

[0011]

Next, an embodiment of a specific combination example of an illumination light-emitting body and sports equipment will be described. [Embodiment 1] FIG. 3 shows a retroreflective material 10 integrally provided on the surface of a frame portion of a tennis racket 11.
The retroreflective material 10 has a minute diffusely reflecting mirror surface on its surface, and receives the illumination light of the stadium to diffusely reflect the light beam at a wide angle, so that the frame of the tennis racket 11 can be more clearly recognized even from a distance. Will be able to

[Embodiment 2] FIG. 4 shows an example in which a polarized light reflecting material 12 is used on a rubber surface adhered to a striking surface of a table tennis racket 13. When receiving the illumination light of the stadium and reflecting the luminous flux, the wavelength period is partially shifted by 180 degrees, so the striking surface of the racket may look like a stripe due to the effect of light interference fringes. In order to make it look, you can adopt an unusual taste, such as an exhibition match.

Embodiment 3 FIG. 5 shows a holographic reflector 14.
On the surface of the ice hockey helmet 15. The helmet receives the irradiation light of the stadium and generates irregularly-reflected light beams whose wavelengths are spectrally separated, so that a light image having interference light having a different color tone depending on the viewing position can be obtained.

[Embodiment 4] FIG. 6 shows a case where a fluorescent substance 16 which is a phosphorescent material is used as a surface material of a baseball bat 17. The bat 17 is irradiated with light to stimulate a fluorescent substance, emits fluorescent light, and shines pale.

[Embodiment 5] L. By applying (electroluminescence) to the wall or ceiling of an exercise facility, it is possible to project characters and images by irradiating the part with a laser beam of ultraviolet light.

[0016]

As described above, according to the present invention, a retroreflective material, a polarized light reflective material, a holograph, a fluorescent material, or an E.C. L. Various sports equipment such as baseball bats and balls, tennis rackets and balls, or table tennis balls, and the visual recognition of such equipment by making a part of the sports equipment illuminated with a material that emits illumination light such as illumination In addition to improved characteristics, the present invention has features such as being able to improve fashion in sports that appeal to the sight, and the effects obtained by implementing the present invention are extremely large.
