[Diagram 3] FIG. 3 is a perspective view of the bottom surface of the baseball batting training device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] FIG. 1 shows a perspective view of a baseball batting training device according to an embodiment of the present invention, FIG. 2(a) shows a back view of the same, FIG. 2(b) shows a left side view of the same, FIG. 2(c) shows a plan view of the same, FIG. 2(d) shows a right side view of the same, FIG. 2(e) shows a front view of the same, and FIG. 3 shows a perspective view of the bottom of the same, and their configuration and operation will be described.

[0013] As shown in these figures, the flat surface 2 of the baseball batting training tool 1 is composed of inclined surfaces 2a, 2b that are inclined toward the inside of the baseball batting training tool 1 at a predetermined angle with respect to a plane (plane on the X-axis and Y-axis in FIG. 1) that is perpendicular to the bottom of the side surfaces 3A, 3B (Y-axis direction in FIG. 1) and parallel to the longitudinal direction of the baseball batting training tool 1 (X-axis direction in FIG. 1), and arc surfaces 2c, 2d that are continuous with each end of the inclined surfaces 2a, 2b and protrude in an arc shape with a predetermined curvature. The part where each end of the arc surfaces 2c, 2c is connected is the apex 2e. The flat surface 2 of the baseball batting training tool 1 thus configured has a plurality of convex portions 2f formed at equal intervals parallel to the longitudinal direction of the baseball batting training tool 1. Furthermore, plate portions 2g, 2h for engraving a product logo or the like are also formed.

[0014] A plurality of auxiliary support parts 4 parallel to the side parts 3A, 3B are formed at equal intervals on the inner surface of the flat part 2, and a cross-shaped auxiliary support pattern part 5 is formed on the inner surface between the side parts 3A, 3B and the auxiliary support parts 4 and on the inner surface between adjacent auxiliary support parts 4. By forming the auxiliary support parts 4 and the auxiliary support pattern part 5 on the inner surface of the flat part 2 in this way, the load such as the weight of the user during batting practice can be dispersed, and the shock absorption can be improved. Also, by making the inner surface of the baseball batting training tool 1 substantially hollow in this way, it is possible to minimize the material and reduce the weight.

[0015] Here, for example, the dimensions of the baseball batting training tool 1 are as follows: height H is 10mm to 150mm, preferably 40mm to 80mm, and particularly 65mm, length L is 50mm to 2000mm, preferably 500mm to 1500mm, and particularly 1000mm, width W is 20 to 500mm, preferably 100mm to 260mm, and particularly 180mm, inclination angle of inclined surfaces 2a and 2b with respect to a plane perpendicular to side surface portions 3A and 3B and parallel to the longitudinal direction of baseball batting training tool 1 is 0 to 89°, preferably 20° to 50°, and particularly 35°, curvature of arc surfaces 2c and 2d is R91. ABS resin or the like can be used as the material, and it can be molded as a single piece by injection molding or the like.

[0016] In such a configuration, when actually using the baseball batting training device 1, the user places the baseball batting training device 1 at his / her feet, places both feet or one foot on the baseball batting training device 1, and performs swinging or batting practice while feeling the position of the center of gravity.

[0017] In general, many users have various problems when hitting a baseball because their body is open. For example, the bat moves toward the ball too early, causing the ball to miss a perfect hit, the force escaping to the outside, causing the ball to lose speed due to lack of power when hit, making it difficult to respond to balls on the outside corner, etc. These are phenomena caused by the body being open during the swing, so it is necessary to improve the opening of the body.

[0018] In this regard, the baseball batting training device 1 according to the embodiment of the present invention is suitable for batting practice because it is possible to improve the posture by repeating swings or batting practice while feeling the position of the center of gravity with the body when standing on tiptoes, thereby preventing the body from opening up.

[0019] As described above, according to the embodiment of the present invention, a baseball batting training tool is provided that is composed of a pair of side sections (3A, 3B), inclined surfaces (2a, 2b) that are perpendicular to the bottom of the side sections and incline inward at a predetermined angle with respect to a plane parallel to the longitudinal direction of the baseball batting training tool, and a flat section 2 that has arc surfaces (2c, 2d) that are continuous with each end of the inclined surfaces and rise in an arc shape with a predetermined curvature. Therefore, it is possible to support the player in learning the optimal posture and center of gravity during swing and batting practice while checking them.

[0020] Although the embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this embodiment and various improvements and modifications can be made without departing from the spirit and scope of the present invention.

[0021] For example, the material is not limited to the above-mentioned ABS resin, and it is of course possible to adopt various resins. [Explanation of symbols]
