Description

  The present invention is a golf ball whose surface changes color when exposed to ultraviolet rays or the like, in particular, providing a region that changes color by applying surface decoration and a region that does not change color, and displays graphics and characters according to the color change of the golf ball. The present invention relates to a golf ball that can be used.

  A golf ball is composed of, for example, a central core and a cover that covers the core. However, as pigments that change color due to ultraviolet light, temperature, and the like are developed, by adding these to a molding material of the cover, specific conditions are satisfied. Thus, a golf ball whose surface color changes can be manufactured.

  In such a golf ball, the color of the golf ball gradually changes when the ball is continuously used on a sunny course because sunlight is applied to the ball during play and the color can be changed. On the way, the golf ball can be changed to a completely different color.

  Such golf balls merely change the color of the surface, and are mainly intended to be applied to a large number of practice balls hit at a golf driving range. In other words, a ball that can be discolored over time can be distinguished from a large number of balls that have been hit and time has passed, and a ball that was hit just before, but when actually going out on the green and competing, it is simple Just changing the color of the ball is poor in taste.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a golf ball rich in taste that can make characters and figures stand out as the surface of the golf ball changes from the first color to the second color. I do.

  The golf ball according to the present invention has a surface that changes color from a first color to a second color different from the first color due to receiving sunlight or a change in temperature, and on the outside of the surface, A print layer that displays characters or graphics in the first color, the print layer not being visually recognized before the surface is discolored, and the printing after the surface is discolored. The layer is visible.

  Further, the printing layer is formed of a third color different from any of the first color and the second color, and the first color, and the discoloration of the printing layer before the surface is discolored. Only the third color may be visually recognized, and the third color and the first color of the print layer may be visually recognized in combination after the surface is discolored.

  According to such a structure, a complete design or message is not formed only by the third color that appears from the beginning, but only when the first color appears, the two are combined and a complete design or message appears. It will be.

  Further, the printing layer is formed of the first color and the second color, the printing layer of the second color is visually recognized before the surface is discolored, and the first is after the surface is discolored. It is good also as a structure which the said printing layer of a color can be visually recognized.

  According to such a structure, two types of figures and characters can be represented on the respective print layers, and one of the figures and characters can be selectively displayed before and after the discoloration.

  As described above, according to the golf ball of the present invention, a visually recognizable pattern can be changed as the surface changes from the first color to the second color, and the golf ball 1 is rich in interest. be able to.

(First embodiment)
The above-described embodiment of the golf ball of the present invention will be described with reference to the drawings. 1 and 2 show a golf ball according to the present embodiment.

  As shown in FIG. 1, the configuration of the golf ball of the present embodiment will be described. As shown in FIG. 1, a general golf ball 1 includes a core 2 made of a rubber material having a large coefficient of restitution, and a resin cover 3 obtained by insert-molding the core 2.

  The cover 2 is usually formed of a synthetic resin material such as an ionomer resin, and a special pigment that changes color from white to colored when irradiated with ultraviolet rays (sunlight) is mixed with the cover 2 to thereby form the golf ball 1. The surface can be discolored. As an example, <3,3-Diphenyl-3H-naphto (2,1-b) pyran> is a special pigment that changes color from white to chrome yellow due to ultraviolet light, and is a special pigment that changes color from white to blue. , <1,3-dihydro-1,3,3--6'trimethyl- (2,3-dihydro-1H-indole-1-yl) spiro [2h-indole-2,8 '-[3H] naphto [ 2,1-b] [1,4] Oxazine> and a special pigment that changes color from white to purple <spiro (2H-2,3- (3H) naphtha (2,1-b) (1,4 ) Oxazine) -1,3-dihydro-1,3,3-trimethyl-6 '-(1-piperidinyl> (CAS number; 114747-45-4).

  The golf ball 1 has a printed layer 4 on a surface 1a of the golf ball 1 that shows a predetermined shape or character. The printed layer 4 does not change color and is opaque and hard to peel off, for example, is formed of a urethane-based paint, and is white, for example. Therefore, it is not visible.

  The operation of the golf ball of the present invention will now be described. FIG. 2A shows a state of the golf ball 1 before its surface 1a is discolored. The surface 1a is the first color, white A, and the printed layer 4 is also the first color, white A. For this reason, characters and figures by the print layer 4 are not visually recognized, and at first glance, the golf ball 1 is simply white A.

  Next, when the golf ball 1 is exposed to sunlight for a predetermined time, the surface 1a changes color to yellow B, which is the second color. While the surface 1a is discolored in yellow B, the printed layer 4 in white A is not discolored, and the contrast between the two allows characters and figures on the printed layer 4 to be seen and viewed.

  For this reason, when playing a golf game, characters and figures are initially invisible on the surface 3 of the golf ball 1, but thereafter, the surface 1a is discolored when the golf ball 1 receives a predetermined ultraviolet ray. As a result, characters and figures are relatively visually recognized. For this reason, the golf ball 1 is rich in interest, and various topics can be provided by characters and figures that appear due to discoloration of the surface 1a.

  In addition, if the setting for changing the color according to the predetermined amount of ultraviolet rays is performed, a player using the ball can be notified of the amount of solar radiation. For example, when the amount of solar radiation exceeds a predetermined value, characters or graphics such as “Caution for sunburn!” Or “Caution for sunstroke!” May be displayed to provide a function to alert the competitor.

(Second embodiment)
FIG. 3 shows a second embodiment of the golf ball of the present invention described above. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The golf ball 1 of the present embodiment has the third print layer 6 of the third color, for example, red C, on the surface 1a together with the first print layer 5 of the white A similarly to the first embodiment.

  As a result, the printed layer 6 of red C is visually recognized in both cases, whether the surface 1a of the golf ball 1 is white A before discoloration or yellow B after discoloration. On the other hand, when the surface 1a of the golf ball 1 changes color to yellow B, the first print layer 5 and the second print layer 6 are visually recognized at the same time as in the first embodiment, and a message combining them is displayed. Will be displayed. As shown in FIG. 2A, only the heart mark of the second print layer 5 appears before the color of the golf ball 1 changes, whereas both sides of the heart mark after the color change as shown in FIG. The first print layer 6 appears, the two are combined, and the message “I Love (heart mark) Hawaii” appears.

(Third embodiment)
FIG. 4 shows a third embodiment of the golf ball of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The golf ball 1 of the present embodiment has a second printed layer 8 of yellow B in addition to the first printed layer 7 of white A as in the first embodiment. That is, the first printed layer 7 has the same color as the surface 1a (white A) of the golf ball 1 before discoloration, and the second printed layer 8 has the same color as the surface 1a (yellow B) of the golf ball 1 after discoloration. Is displayed.

  For this reason, in the golf ball 1 of the present embodiment, before the discoloration of the surface 1a, the mark of the first print layer 7 cannot be visually recognized, and only the mark of the second print layer 8 appears. The mark on the print layer 8 disappears, and only the mark on the print layer 7 appears.

  As described above, in the golf ball 1 of the present embodiment, the image appearing on the surface can be changed with the discoloration of the surface 1a.

  In the first to third embodiments, the color of the surface 1a of the golf ball 1 is changed from white A (first color) to yellow B (second color). The first color, the second color, and the third color may be different colors from each other, and are not limited thereto. For example, a golf ball that changes color from a chromatic color such as red to white may be used. Depending on the pigment that changes color, various color combinations are possible.

  Further, in the first to third embodiments, the golf ball whose color is changed by irradiation with ultraviolet rays is described as an example. Golf balls that can be changed can also be used.

  The above invention can change a pattern or a character which can be visually recognized as the surface is discolored, and can be adopted as a golf ball having a richness of interest.
