[Industrial applications]

 The present invention relates to a practice gateball hitting tool.

[0002]

[Prior art]

 Since the head of a conventional gate ball hitting tool is chamfered by 3 mm along the periphery of both ends of a 4.5 cm diameter cylinder, the area of both ends is slightly smaller than the area of the cross section of the middle part. However, it has a substantially uniform thickness. For this reason, it is easier to hit the ball with the end face of the head, but it is difficult to catch the center of the ball at the center of the end face. It is difficult to learn the correct swing so that you can roll in different directions and always catch the center of the ball.

[0003]

[Problems to be solved by the device]

 The purpose of the present invention is to practice training by hitting the center of the ball at the center of the ball hitting tool so that the ball can be rolled in the desired direction. To provide.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the practice gateball hitting tool of the present invention has both end surfaces of the head positioned on the central axis, and the cross-sectional area of the both end surfaces is 65% or less of the cross-sectional area of the intermediate portion. It has a certain configuration.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the gate ball hitting tool 1 is formed by mounting a head 3 having a length of 24 cm and a diameter of about 4.5 cm so as to intersect the shaft 2 at one end of the shaft 2. The head 3 has a circular cross section, and a screw hole 4 is formed at the center of the longitudinal direction from the outer surface to the vicinity of the center of the cut surface along the radial direction, and a male screw portion protruding from one end surface of the shaft 2 is formed. The head 3 and the shaft 2 are attached by screwing 5 into the screw hole 4.

Further, the circumferential surfaces of both ends in the longitudinal direction of the head 3 are tapered from the position of about 3 cm from the tip toward the central axis a, and the areas of both ends are gradually continuous toward the tip. As shown in FIG. 2, both end surfaces 8 and 8 ′ are located on the central axis a of the head 3 and are formed into a circular shape having a small area of 65% or less of the cross-sectional area of the longitudinal middle portion. Has been formed. The diameter of both end surfaces 8 and 8'is typically about 2.5 to 3.5 cm, but the larger the end surface 8, 8'area is, the easier it is to hit the ball. , 8'is made larger and the area of the end faces 8, 8'is made smaller for advanced users.

FIG. 3 shows a second embodiment of the present invention, in which the peripheral surfaces of both ends of the head 3a are concavely curved toward the outer surface and are inclined toward the central axis a, and the areas of both ends are It is being continuously reduced toward. Further, FIG. 4 shows a third embodiment of the present invention, in which the head 3b has a small diameter portion 7 along the central axis a at the center of the end surface of the large diameter portion 6, and the diameter of both ends of the head 3b is It does not tilt continuously, but is gradually reduced in stages.

In the third embodiment described above, the base portion of the small diameter portion 7 becomes weak, so in the fourth embodiment shown in FIG. 5, the diameters of both ends of the head 3c are gradually reduced through a plurality of steps. It The shape of the end faces 8 and 8'of the head may be non-circular, and may be oval like the head 3d shown in FIG. 6 or square like the head 3e shown in FIG. The head 3f shown in FIG. 9 may be rectangular, or the head 3g shown in FIG. 9 may be triangular.

Further, the cross-sectional shape of the intermediate portion of the head may be a non-circular shape, and may be square like the head 3h shown in FIG. 10 or pentagonal like the head 3i shown in FIG. Alternatively, the heads 3j, 3k, 3l shown in FIGS. 12 to 14 may be polygons having more sides. Further, as shown in FIG. 15, one end surface 8 of the head 3m has a diameter of about 2.5 cm, and the other end surface 8'has a diameter of about 3.5 cm, and the areas of the end surfaces 8 and 8'on both sides are changed. It is also possible for a player to use one end face 8 of a large area and a beginner to hit the ball using the other end face 8'of a small area.

Further, the shape of the cross section and the end surface of the head may be polygonal shapes other than those in the drawing, and the shapes of both end surfaces of the head may be different.

[0011]

[Effect of device]

 In the practice gateball hitting tool of the present invention, both end surfaces of the head are provided on the central axis of the head, and the area of both end surfaces is set to 65% or less of the cross-sectional area of the middle portion. It is not possible to hit the ball at a part far from the center axis of the head, and it is obvious that if the ball is hit on a part other than the narrow striking surface located on the center axis of the head, it is a wrong swing. As a result, the habit of swinging to hit the center of the ball at the center of the end face is acquired, and the skill improves so that the player can roll the ball in the target direction. In addition, only the area of both end faces is reduced and the middle part has the same size as the conventional one, so the weight reduction is small and the feel of swing is the same as that of a normal ball hitting tool.
