[0009] Embodiments of the present invention will be described below with reference to the drawings. Unless otherwise specified, the same or corresponding parts in the following drawings will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0010] The configuration of a golf club head, as an example of a striking tool according to the embodiment, will be described. Specifically, the striking tool according to the embodiment is a putter head. However, the striking tool according to the embodiment is not limited to a golf club head; any striking tool capable of creating recessed areas, such as a bat or racket, may be used.

[0011] Referring to Figure 1, a golf club head 100, as an example of a striking tool W, comprises a sole portion 1, a face portion 2, a back portion 3, a toe portion 4, and a heel portion 5.

[0012] The golf club head 100 comprises a surface portion 10 and a design portion 20. In this embodiment, the surface portion 10 and the design portion 20 are each provided on the sole portion 1. The design portion 20 is the part to which the design is applied. In a plan view, the design portion 20 is configured in shapes such as straight lines, curves, X-shapes, and T-shapes.

[0013] In this embodiment, the design portion 20 is configured in a rectangular shape in plan view. The design portion 20 extends in a second direction D2 perpendicular to the first direction D1. The first direction D1 is the short-side direction of the design portion 20. The second direction D2 is the long-side direction of the design portion 20. The first direction D1 is the face-back direction where the face portion 2 and the back portion 3 face each other. The second direction D2 is the toe-heel direction where the toe portion 4 and the heel portion 5 face each other. The design portion 20 is located near the face portion 2 in the face-back direction. The design portion 20 is located on the toe portion 4 side in the toe-heel direction. Note that the position of the design portion 20 is not limited as long as the design portion 20 is visible.

[0014] Referring to Figure 2, the surface portion 10 and the design portion 20 will be described. In this embodiment, the surface portion 10 is configured to be planar. However, the surface portion 10 may also be configured to be curved.

[0015] The design portion 20 includes a recess 21 that is recessed from the surface portion 10. The recess 21 of the design portion 20 includes a side surface S that is connected to the surface portion 10.

[0016] The side surface S has two inclined surfaces IS that are inclined with respect to the surface 10 and face each other. In this embodiment, the side surface S has a side wall SW connecting the surface 10 and the two inclined surfaces IS. The side wall SW is configured to be approximately perpendicular to the surface 10. Note that the side surface S does not have to have a side wall SW. In other words, each of the two inclined surfaces IS of the side surface S may be in contact with the surface 10.

[0017] The two inclined surfaces IS are inclined such that the depth increases from both ends of the recess 21 towards the center in the first direction D1. The two inclined surfaces IS are connected to each other at the center in the first direction D1. The two inclined surfaces IS are inclined such that the depth is greatest at the center in the first direction D1.

[0018] In the recess 21, the two inclined surfaces IS are configured in a V shape. The two inclined surfaces IS are configured in a V shape in a cross-section along the first direction D1, or in other words, in a cross-section orthogonal to the second direction D2. Each of the two inclined surfaces IS is configured linearly in said cross-section.

[0019] The first direction D1 is along the direction in which the two inclined surfaces IS face each other. In the first direction D1, the depth dimension M1 at both ends of the two inclined surfaces IS is smaller than the depth dimension M2 at the center of the two inclined surfaces IS. The depth dimension M1 at both ends of the two inclined surfaces IS is, for example, 0.3 mm. The depth dimension M2 at the center of the two inclined surfaces IS is, for example, 0.4 mm. The angle A1 formed by each of the two inclined surfaces IS with the adjacent side wall SW is, for example, 105°. The angle A2 formed by the two inclined surfaces IS with each other is, for example, 150°. Since the effect of the invention is more easily obtained when the angle A2 is steeper, it is preferably set to 100° to 150°.

[0020] A color label paint is applied to the surface of each of the two inclined surfaces IS. That is, a coating film 22 to which a color label paint is applied is disposed on the surface of each of the two inclined surfaces IS. The color label paint is, for example, painted with coloring or aerosol ink. Thereby, the polarization effect can be enhanced.

[0021] For example, the thickness of the color label paint is 0.01 mm or more and 0.15 mm or less. The effect of polarization can be particularly easily obtained by thinning the thickness by spray coating.

[0022] Referring to Figure 3, the color tones of the color travel paint on the two inclined surfaces IS will be explained. In Figure 3, the dots indicated on the figure show the differences in the color tones of the color travel paint. Color travel paint is a paint characterized by its color tone changing as the angle of light entry and reflection changes. Color travel paint contains polarizing paint and polarizing pearl pigment. Since the angle of the viewer's line of sight to the two inclined surfaces IS and the angles formed by the two inclined surfaces IS are different from each other, the angles of light entry and reflection onto the color travel paint coating 22 are different from each other. For this reason, the color tones of the color travel paint coating 22 appear distinctly different to each viewer.

[0023] Next, with reference to Figure 4, Modification 1 of the recess 21 will be described. In Modification 1 of the recess 21, the two inclined surfaces IS in the recess 21 are inclined such that their height increases from both ends of the recess 21 towards the center in the first direction D1. The two inclined surfaces IS are inclined such that their height is greatest in the center of the first direction D1. In the recess 21, the two inclined surfaces IS are configured in an inverted V shape. The two inclined surfaces IS are configured in an inverted V shape in a cross section along the first direction D1, in other words, in a cross section perpendicular to the second direction D2. Each of the two inclined surfaces IS is configured in a straight line in that cross section.

[0024] Furthermore, with reference to Figure 5, a modified example 2 of the recess 21 will be described. In modified example 2 of the recess 21, the two inclined surfaces IS in the recess 21 are configured in a U-shape. The two inclined surfaces IS are configured in a U-shape in a cross-section along the first direction D1, in other words, in a cross-section perpendicular to the second direction D2. Each of the two inclined surfaces IS is configured in a curved shape in that cross-section. The two inclined surfaces IS as a whole are configured in a U-shape.

[0025] Furthermore, a modified example of the design portion 20 will be described with reference to Figure 6. In the modified example of the design portion 20, the design portion 20 is configured in a substantially X shape in plan view. Specifically, the design portion 20 includes a recess 21. The recess 21 is configured in a substantially X shape in plan view.

[0026] The effects and benefits of the striking tool W according to this embodiment will be explained. According to the striking tool W of the embodiment, a coating 22 is provided on each of the two inclined surfaces IS, which is coated with color travel paint. Since the angle of the viewer's line of sight to the two inclined surfaces IS and the angle formed by the two inclined surfaces IS are different from each other, the angles of light entry and reflection to the coating 22 of the color travel paint are different from each other. For this reason, the color tones of the coating 22 of the color travel paint placed on each of the two inclined surfaces IS appear distinctly different to the viewer. Thus, the complex hues of the color travel paint can be fully brought out. In particular, even in still images such as catalogs and photographs, two or more colors can be recognized. As a result, it is possible to realize a design that feels advanced and attracts consumer interest using color travel paint.

[0027] According to the striking tool W of this embodiment, the complex shades of the color travel paint can be fully brought out by arranging the two inclined surfaces IS in a V-shape in the recess 21.

[0028] According to the striking tool W of this embodiment, the complex shades of the color travel paint can be fully brought out by arranging the two inclined surfaces IS in an inverted V shape in the recess 21. Furthermore, because the two inclined surfaces IS are arranged in an inverted V shape, the color travel paint flows downward from the apex formed by the two inclined surfaces IS during application. For this reason, the color travel paint is less likely to accumulate at the apex formed by the two inclined surfaces IS. The apex formed by the two inclined surfaces IS forms the boundary between the paint films 22 of the color travel paint placed on each of the two inclined surfaces IS, thus clarifying the boundary between the paint films 22 of the color travel paint placed on each of the two inclined surfaces IS.

[0029] According to the striking tool W of the embodiment, the two inclined surfaces IS in the recess 21 are configured in a U-shape. Therefore, by configuring the two inclined surfaces IS in the recess 21 in a U-shape, the complex shades of the color travel paint can be fully brought out.

[0030] According to the striking tool W of this embodiment, the thickness of the color travel paint is 0.01 mm or more and 0.15 mm or less. This allows the complex hues of the color travel paint to be fully brought out.

[0031] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description and is intended to include all modifications in the sense and scope equivalent to the claims.
