Description

[Technical Field]

[0001] The present invention relates to a hitting exercise implement having a hitting part, a shaft part connected at one end to the hitting part, and a grip provided on the shaft part. [Background technology]

[0002] A conventional hitting exercise implement disclosed is a badminton racket that has a face, a hollow shaft, and a grip, with ribs extending along the axis of the shaft provided on at least a portion of the inner surface of the shaft (see, for example, Patent Document 1). This badminton racket was developed with the objective of increasing the bending rigidity and torsional rigidity of the shaft, improving flexibility in the direction perpendicular to the face surface, and reducing flexibility in the lateral direction of the racket along the face surface. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-117363 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the badminton racket described in Patent Document 1 had the problem that when trying to hit a shuttlecock hit by an opponent with more force or with a sharp backswing, the shaft bends, making it difficult to hit the shuttlecock back with force. Also, because the shaft bends, it was difficult to control the shuttlecock.

[0005] The present invention has been made with a focus on these problems, and aims to provide a hitting exercise tool that suppresses bending and twisting of the shaft portion in the swing direction, allows for strong hits, and is easy to control when hitting. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the hitting exercise equipment of the present invention is a hitting exercise equipment having a hitting portion, a shaft portion connected at one end to the hitting portion, and a grip provided on the shaft portion, characterized in that the shaft portion has a shape in which two identical long pieces having a U-shaped cross section and both edges bent outward are joined to each other in a tubular shape at both edges, and both edges extend in the longitudinal direction of the shaft portion and protrude from the base in the swing direction or opposite direction of the shaft portion.

[0007] The hitting exercise equipment of the present invention has a shaft portion which consists of two identical long pieces with a U-shaped cross section and both edges bent outward, joined together at both edges to form a tube, and both edges extend in the length direction of the shaft portion and protrude from the base in the swing direction or opposite direction of the swing of the shaft portion, thereby suppressing bending and twisting of the shaft portion in the swing direction, allowing for powerful hits and making it easier to control the hit.

[0008] The hitting exercise equipment of the present invention preferably has a long, thin reinforcing plate that is provided inside the shaft portion and has both edge portions connected to the inner surface of the shaft portion perpendicular to a plane passing through the joint surface of the elongated object. In this case, the reinforcing plate further reduces bending and twisting of the shaft portion in the swing direction, allowing for stronger return hits and easier control when hitting.

[0009] The hitting exercise implement according to the present invention preferably comprises a badminton racket, the hitting part comprises a racket head, and the swing direction and the counter-swing direction are preferably the front or rear direction of the racket head. In this case, bending and twisting of the shaft in the swing direction is suppressed, allowing for powerful hits and making the badminton racket easier to control when hitting.

[0010] The shaft portion is preferably made of titanium, carbon, resin, aluminum alloy, etc. The two edges of the elongated object are preferably joined by welding or by adhesive. The hitting exercise implement according to the present invention may comprise a badminton racket, as well as a tennis racket, a squash racket, a golf club, a hockey stick, or a baseball bat. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a hitting exercise tool that can suppress bending and twisting of the shaft portion in the swing direction, allows for strong hits, and is easy to control when hitting. [Brief explanation of the drawings]

[0012] [Figure 1] 1 is a front view showing a hitting sports tool according to an embodiment of the present invention. [Figure 2] 2 is an enlarged end view of the hitting exercise tool shown in FIG. 1 taken along line AA. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a hitting exercise device according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the hitting exercise equipment of the embodiment is a badminton racket, and has a hitting portion 1, a shaft portion 2, a grip 3, and a reinforcing plate 4.

[0014] The hitting portion 1 is made up of a racket head. One end 2a of the shaft portion 2 is connected to the hitting portion 1. The grip 3 is provided on the other end of the shaft portion 2 so as to cover the shaft portion 2. The shaft portion 2 is manufactured by the following method: a pipe material is cut lengthwise into two equal halves, and the two long pieces are subjected to external pressure to form a U-shaped cross section, with both edges of each piece bent outward. The two identical long pieces 21, 22 are then joined together at their edges 21a, 22a by welding or adhesive to form a tubular shape. The shaft portion 2 has a substantially elliptical cross section.

[0015] The reinforcing plate 4 is made of a long, narrow stainless steel plate. The reinforcing plate 4 has approximately the same length as the shaft portion 2 and approximately the same width as the longest inner diameter of the shaft portion 2. The reinforcing plate 4 is provided inside the shaft portion 2, and both edge portions are bonded to the inner surface of the shaft portion 2 with an adhesive, perpendicular to a plane passing through the joint surfaces of the elongated members 21 and 22. The reinforcing plate 4 is arranged along the longest inner diameter of the shaft portion 2.

[0016] The shaft portion 2 thus manufactured is attached to the hitting portion 1 so that both edges 21a, 22a extend in the longitudinal direction of the shaft portion 2 and protrude perpendicularly from the base portion 23 in the swing direction or the opposite direction of the shaft portion 2. The swing direction and the opposite direction of the swing direction are the front and back directions of the racket head.

[0017] The hitting exercise implement of this embodiment has a shaft portion 2 formed by joining two identical long members 21, 22, each with a U-shaped cross section and both edges bent outward, at both edges 21a, 22a to form a tube, and both edges 21a, 22a extend along the length of shaft portion 2 and protrude perpendicularly from base portion 23 in the direction of swing of shaft portion 2 or in the opposite direction to the swing, thereby suppressing bending and twisting of shaft portion 2 in the swing direction, allowing for powerful hits and easier control when hitting. This allows for a fun game of badminton. Furthermore, the reinforcing plate 4 further suppresses bending and twisting of the shaft portion 2 in the swing direction, allowing for stronger return hits and easier control when hitting.

[0018] Although a badminton racket has been shown as an example in this embodiment, the hitting exercise implement of this embodiment may also be a tennis racket, a squash racket, a golf club, a hockey stick, or a baseball bat. [Explanation of symbols]
