Description

  The present invention relates to a tea batting practice tool such as baseball.

A conventional tee batting practice method such as baseball is a practice method in which two persons play a pair, lightly toss the ball toward the batter, and the batter strikes back the toss ball with a bat in time. At this time, there is an advantage that the person who has tossed can check the batting form of the batter. However, to practice effectively, the tossers must always throw the ball in a certain position, which was very difficult not only for children but also for adults.
On the other hand, each of the following patent documents discloses practice tools that allow such tea batting practice to be performed by one person. In the hitting practice tool disclosed in each document, a ball guide member for guiding the ball is provided instead of a person tossing the ball with his / her hand so that the hitter can perform hitting practice such as baseball and tennis alone. The ball placed on the ball guide member begins to roll on the ball guide member by an operation such as a foot switch of the batter and is released from the tip of the ball guide member. It is designed to strike together. In these hitting practice tools, a column supporting a ball guide member is integrally provided upright on a base formed in a disc shape or a square plate shape.

  However, the practice tool for single practice as described above cannot be folded and stored in a small structure due to the structure in which the support and the base are integrally provided, and a large space is required for storing the hitting practice tool after the practice. Need. Also, the practice of batting alone means that there is no one who checks the batting form, there is only a method of looking at itself using a mirror etc., but the important form at the time of batting and immediately before and after that is I couldn't confirm it because my eyes went to the ball. Furthermore, conventionally, there was only a practice method of hitting the ball that floated after one bounding in a timely manner, so the dynamic visual acuity cultivated by watching and hitting the ball while falling was not acquired.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a tea batting practice tool that can be folded compactly and stored in a small space and can perform an effective batting practice. .

  In order to achieve the above object, a tea batting practice tool according to the present invention has an inclined guide surface, and a ball guide member that guides a ball placed on the guide surface and releases it from the tip is an angle adjusting member. The tilt angle is held variable, and the angle adjusting member is supported by a leg-folding tripod.

  In the above configuration, the ball guide member has a substantially V-shaped cross section when viewed in the ball guide direction.

  In each of the above-described configurations, the angle adjusting member is supported on the tripod so that the height is variable.

  Furthermore, in each of the above-described configurations, the base of the tripod that supports the connecting portion of the angle adjusting member is formed so that the connecting portion of the angle adjusting member and the handle of the parasol can be replaced.

  Since the present invention is configured as described above, the tripod supports the ball guide member and the angle adjusting member, and after practice, the tripod leg is folded to shrink the whole, and the angle of the ball guide member is expanded. By making it parallel to the legs, the tea batting practice tool can be made very compact, the storage space is small, and the structure is simple, so that it can be manufactured at low cost. Also, since the tripod is supported at three points instead of surface support, even if the ground is somewhat uneven, it does not wobble when the tea batting practice tool is installed, it has good stability, and if the tripod leg is opened wide, A sense of stability increases. Apart from this, the present invention is for two-person hitting practice, so when one person puts the ball on the inclined guide surface of the ball guide member, this ball is guided by the guide surface and the ball guide By practicing the batter being released from the tip of the member and hitting the bat against the bat in a predetermined position with the ball in the middle of falling, one person can check the batter's form, I can give guidance.

  When the ball guide member has a substantially V-shaped cross section when viewed in the ball guide direction, the ball can be supported in a state close to point contact when the ball rolls on the ball guide member. Compared to the case where the ball is supported in a state close to surface contact, such as when the guide member is semicircular when viewed in the ball guiding direction, the rolling resistance of the ball can be reduced, so the repeatability of the ball discharge position is reduced. Can be practiced effectively to consolidate the batter's form.

  And when the ball guide member is attached to a tripod with variable height, it is possible to freely change the height at which the ball is released, and a wide range of people from children to adults with different hit points I can practice.

  Furthermore, when the base of the tripod is formed so that the connecting portion of the angle adjustment member and the handle of the parasol can be freely replaced, the ball guide member and the angle adjustment member are removed from the tripod and replaced with a parasol during a game such as baseball. be able to. This makes it possible for spectators of the game to enter the parasol in a hot or rainy day to block out direct sunlight and rain, and if the tripod legs are wide open, even if there is a strong wind, it will not fall easily .

The best embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example embodying the present invention, and does not limit the technical scope of the present invention. FIG. 1 is a perspective view of a tea batting practice tool according to an embodiment of the present invention. FIG. 2 is an enlarged view of a ball guide member and an angle adjustment member of the tea batting practice tool according to an embodiment of the present invention. 3 is a partial cross-sectional view of a tea batting practice tool according to an embodiment of the present invention. In each figure, a tea batting practice tool 1 according to the present embodiment has a ball guide member 2 and a ball guide member 2 with variable inclination angles. And a tripod 4 for supporting the ball guide member 2 and the angle adjusting member 3 at a predetermined height position.
The ball guide member 2 is formed of a steel material, has a guide surface 5 in which the inclination of the ball guide member 2 in the longitudinal direction forms an angle θ with respect to the horizontal, and a cross section viewed in the ball guide direction (arrow L direction) is substantially V-shaped. It is formed in a shape.

  The angle adjusting member 3 includes an angle fixing portion 7 and a connection portion 11, and the upper portion of the angle fixing portion 7 is fixed to the lower surface of the ball guide member 2, and the lower portion of the angle fixing portion 7 is formed to hang down into two branches. Yes. The bifurcated portion of the angle fixing portion 7 and the connecting portion 11 disposed below the angle fixing portion 7 are respectively provided with shaft holes that communicate in series in the horizontal direction. Bolts 8 are passed through these shaft holes, and a cap nut 9 with a handle is screwed to the tip of the bolt 8, whereby the angle fixing part 7 and the connecting part 11 are fixed at the vertical angle at that time. The angle fixing part 7 is swingable up and down around the shaft hole with respect to the connection part 11.

  The lower part of the connection part 11 is formed in an elongated tubular shape, is slidably accommodated in the inner tubular member 17 of the tripod 4 (base of the tripod referred to in the present invention), and is screwed by a knob 13a with a bolt. ing. The tripod 4 includes an inner tubular member 17, an outer tubular member 18, a collar 19, legs 14, 14, 14, etc., and the inner tubular member 17 is slidably received in the lower outer tubular member 18, and has a bolted knob. It is screwed by 13b. The height of the tip 16 portion of the ball guide member 2 can be freely adjusted within a range of 123 cm or more and 225 cm or less by extending and contracting the connecting portion 11 and the inner tubular member 17 and screwing them to a predetermined height by the knobs 13a and 13b. .

  The upper ends of the legs 14, 14, 14 of the tripod 4 are swingably connected to the collar 19, and the central portions in the longitudinal direction of the legs 14, 14, 14 and the lower ends of the outer tubular members 18 are arms 20, 20, 20. It is connected so that it can swing. The outer tubular member 18 is slidably inserted into a vertical cylindrical collar 19 at the top, and is fixed to a predetermined height position by being screwed by a knob 13c with a bolt.

The operation of the tea batting practice tool 1 will be described below.
When one person puts the ball 6 on the inclined guide surface 5 of the ball guide member 2, the ball 6 rolls on the guide surface 5 due to gravity and the ball guide member 2 Guided by the tip 16 and discharged from the tip 16. The released ball 6 in the middle of falling is hit by the batter when it falls to a predetermined position with no bound. At this time, one person can observe and confirm the batter's form as an instructor or assistant while placing the ball 6 on the ball guide member 2, and can give appropriate guidance on the batter's batting form. Thus, the tea batting practice tool 1 can be made into a simple structure for practice by a pair of two persons, and can be manufactured at low cost.

  In particular, since the guide surface 5 of the ball guide member 2 has a substantially V-shaped cross section when viewed in the ball guide direction, the ball 6 is close to point contact when the ball 6 rolls on the guide surface 5. Can be supported in a state. Therefore, the rolling resistance of the ball 6 can be reduced compared to the case where the ball is supported in a state close to surface contact, such as when the ball guide member 2 is semicircular when viewed in the ball guiding direction, and the tip 16 The repetition accuracy of the ball 6 release position from the ball becomes high, and it is possible to practice effectively for the batter's form hardening.

Further, since the ball 6 that is in the process of falling is hit without bound, the moving speed of the ball 6 is faster than that when hitting a one-bound ball. Nourished.
Further, by adjusting the distance between the position of the ball 6 discharged from the tip 16 of the ball guide member 2 and the position where the batter stands, the practice of hitting each course such as the inner angle if the distance is short, the outer angle if the distance is long, etc. Is possible.

  If the batter adjusts the height of the hitting point when the batter hits the ball 6 released from the tip 16 without changing the height of the ball guide member 2, he can practice hitting each course such as increasing and decreasing the hitting point. In other words, if the ball 6 released from the tip 16 of the ball guide member 2 is swung to catch the ball at a high position by swinging the bat at an early stage after the release, the hitting practice of the high course is achieved. If you catch the ball so as to sprinkle the bat at a low position after a while, you can practice hitting the lower course.

To adjust the angle of the ball guide member 2, the cap nut 9 with handle is loosened, and after adjusting the angle θ of the ball guide member 2 to a predetermined angle, the cap nut 9 with handle is tightened and fixed.
When the angle θ from the horizontal of the ball guide member 2 is large, the speed of the ball 6 guided by the guide surface 5 and discharged from the tip 16 of the ball guide member 2 is increased, and the batter must swing the bat at a fast timing. Do not hit the ball 6. Therefore, it is possible to practice hitting high-speed ball types such as straight balls and sliders. On the other hand, when the angle θ from the horizontal of the ball guide member 2 is small, the speed of the ball 6 guided by the guide surface 5 and discharged from the tip 16 of the ball guide member 2 is slow, and the batter is batted at a slow timing. If it is not shaken, it will not hit the ball 6. Therefore, it is possible to practice hitting against a changing ball such as a curve and so-called “try to hit” which is important for the batter.

  If the tee batting practice tool 1 itself is moved when the right batter and the left batter practice sequentially, the height of the ball guide member 2 and the inclination angle θ from the horizontal will vary slightly, making it very difficult to adjust. Become. That is, the tee batting practice tool 1 has a batter on the right batter on the first side when the batter stands in the bat and the batter on the left batter so that the ball 6 returned by the batter does not hit the tee batting practice tool 1 directly. It will be installed on the 3rd base when standing in a bat. Here, when the bat batting practice tool 1 itself is moved from the first base side to the third base side by changing the batter of the batter, the height of the ball guide member 2 and the inclination angle θ from the horizontal are slightly changed, and the optimum conditions It will take a lot of labor to re-align. Therefore, without changing the height of the ball guide member 2 and the inclination angle θ from the horizontal, the knob 13a is loosened while the tripod 4 is installed at the same position, and the connecting portion 11 of the angle adjusting member 3 is rotated about 90 degrees. Screw in place. As a result, the guide direction of the ball 6 that was parallel to the space between the single ribs is changed so as to be parallel to the space between the three ribs, and the ball 6 is released to a predetermined position from the tip 16 of the ball guide member 2 after the change. Thus, if the batter moves the position of the bat, it is almost unnecessary to adjust the height of the ball guide member 2 and the inclination angle θ from the horizontal.

  The height of the ball guide member 2 and the angle adjusting member 3 can be adjusted by loosening the knob 13a of the tripod 4 and pulling out the lower part of the connecting portion 11 from the inner tubular member 17 or housing it in the inner tubular member 17, Adjustment can be made by loosening the knob 13 b and pulling the inner tubular member 16 out of the outer tubular member 18 or housed in the outer tubular member 18. Accordingly, the height at which the ball 6 is released can be freely changed, and a wide range of people from children to adults having different optimum hitting point heights can practice.

  Since the ball guide member 2 and the angle adjusting member 3 are supported by a tripod 4 and the tripod 4 is supported by three points instead of a surface support, the tea batting practice tool 1 does not wobble even if there are some irregularities on the ground or the like, and is stable. If the three legs 14, 14, 14 are opened widely, the sense of stability is further increased. Further, since the tripod 4 is composed only of a skeleton, it is light and easy to carry.

  Since the ball guide member 2 and the angle adjusting member 3 are supported by the tripod 4, the legs 14, 14, 14 of the tripod 4 are folded and expanded in a straight line after practice so that the connecting portion 11 of the angle adjusting member 3 is connected. By accommodating in the inner tubular member 17 of the tripod 4, accommodating the inner tubular member 17 in the outer tubular member 18 and shrinking the whole, and making the angle of the ball guide member 2 parallel to the extended leg 14, The tea batting practice tool 1 can be made very compact, and the storage space can be small.

  Furthermore, the outer tubular member 17 of the tripod 4 is formed so that the handle 22 of the parasol 15 can be inserted as shown in FIG. Therefore, at the time of a game such as baseball, the ball guide member 2 and the angle adjusting member 3 can be removed from the tripod 4 and replaced with a commercially available parasol 15 or the like. As a result, when watching a game under harsh conditions such as hot weather or rainy weather when not performing tea batting practice, if the spectator enters the parasol 15, it can block direct sunlight and rain, Further, if the legs 14, 14, 14 of the tripod 4 are opened widely, it will be difficult to fall even if there is a strong wind.

  In the above embodiment, baseball tee batting practice has been described. However, the tea batting practice tool of the present invention can be used for both soft baseball and hard baseball, for example, and for softball hitting practice. Available. The material of the ball guide member 2 is not limited to steel, and may be a metal such as aluminum or a synthetic resin such as vinyl chloride.
