Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a tennis training device that allows users to practice serves, etc. by hitting a ball attached to a string with a racket.

(Prior Art) Recently, the number of people playing tennis has been increasing, which is called a tennis boom, and along with this, tennis courts are being constructed in various places. However, the expansion of tennis courts has not kept up with the rapid increase in the number of tennis players, and as a result, tennis schools are overflowing with trainees, making it difficult for them to sufficiently practice their serves and other skills.

Therefore, various tennis practice tools have been proposed that allow players to learn correct serves and the like without actually going out on the court.

(Problem that the invention aims to solve) However, many of these tennis practice devices have a structure in which the string to which the ball is attached is directly attached to the support frame, and as a result, it is troublesome to adjust the position or height of the ball. This is extremely inconvenient when practicing with people of different heights, and what's more, the moment you hit the ball, you feel resistance other than the ball's repulsive force (device resistance including strings, etc.), which makes it difficult to feel the ball as it should be when serving. Also, in the case of a serve, especially if it is a flat serve, the ball must fly in a certain direction relative to the position and angle of the server, but with conventional practice equipment, the ball does not fly in a certain direction. Since it is impossible to know whether the racket is flying in the correct direction, that is, whether the racket is placed correctly, the practice effect cannot be expected to be very effective.

Therefore, an object of the present invention is to provide a tennis practice tool that allows the height of the ball to be easily adjusted, provides the feel of hitting the ball as it should when serving, and can sufficiently enhance the practice effect.

(Means and effects for solving the problems) In order to solve the above problems, the present invention provides support columns 6 and 7 that are erected at a predetermined distance apart.
Tennis practice tool 1 in which a string 39 with a ball 38 attached therebetween is attached horizontally so as to be movable in the vertical direction
At least one of the pillars 7 is provided with a direction support member 35 whose inclination angle can be changed in the direction in which the ball 38 is hit.
A slide rope 36 is stretched through the slide rope 36, and one end of the string 39 is slidably attached to the slide rope 36, so that the ball 38 only swings when hit in the direction in which the slide rope 36 is provided. The vibration (reciprocating damped vibration) subsides quickly, and the feel of the ball is similar to that of hitting a real ball. On the other hand, as the direction in which the ball 38 is hit deviates from the direction in which the slide rope 36 is provided, the ball 38 begins to rotate using both ends of the string 39 as support, and it takes a long time to come to rest. In addition, the feel of the ball at impact is significantly different from the original one, making it impossible to obtain a comfortable feel.

In this way, the ball can be hit at the correct height, and feedback is always given to the practitioner as to whether the ball has been hit in the correct direction, thereby further improving the effectiveness of practice.

(Embodiments) Preferred embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a plan view of the tennis practice equipment according to the present invention;
Figure 2 is a view in the direction of arrow A in Figure 1, and Figure 3 is a view in Figure 1 B.
FIG. 4 is a partially enlarged perspective view of the tennis practice tool.

In the tennis practice device 1, reference numeral 2 denotes a support frame body consisting of support parts 3 and 4 erected on both left and right sides and a connection part 5 connecting these parts, all of which are made of pipe members.

In the support parts 3 and 4, reference numerals 6 and 7 indicate pillars that are vertically installed approximately at the center of each support part 3 and 4, respectively. Further, reference numerals 8 and 9 are provided in the shape of legs at the front and rear of the inner downward direction of the support frame 2 from the upper end of each support column 6 and 7,
These are support pipes for stabilizing the pillars 6 and 7, and base parts 10 and 11 are formed at the bottom of these pipes to improve the grounding properties of the training tool 1. Each base 10, 11 is provided with extending portions 10a, 11a whose front and rear sides extend outward, and slide ropes 12, 13 for stroke are attached to the tips of these portions. On the other hand, extending portions 14 and 15 are also provided outward from the upper ends of the support pipes 8 and 9, and one end portion of the string bodies 18 and 19 to which the balls 16 and 17 are attached is the tip of the extending portions 14 and 15. The other ends of these are attached to the ring member 2.
0, 21 through the slide ropes 12, 13
can be slidably attached to. The balls 16 and 17 thus provided are used for practicing strokes. Incidentally, reference numerals 26 and 27 indicate each extension portion 10.
This is a reinforcing member for the supporting parts 3 and 4, which connects the supports 3 and 10a and 11a and 11a, and connects the lower ends of the pillars 6 and 7 to the central part.

Now, in the support columns 6, 7, the support pipes 8,

... will be fixed. This guide member 30, ..., 3
The height adjustment ropes 32, 33 are inserted into 1, . . . to form a loop shape, and the lowermost guide members 30a,
Tie it to 31a. A sliding member 34 is fitted into one of the pillars 7 so as to be able to slide up and down along this pillar 7, and the loop-shaped height adjustment rope 33 is attached to a part of the sliding member 34. A rod-shaped direction indicating member 3 is provided on the part facing the 6 side.
5 is attached so that its inclination angle can be changed freely, and slide ropes 36 are attached to both ends of this direction indicating member 35.
Attach both ends of the The sliding member 34 is provided with a notched groove 34a in the vertical direction on its inner periphery, and a guide key 37 provided on the support column 7 is fitted into the notched groove 34a, thereby restricting its rotational movement.

A string 39, to which a ball 38 for serve practice is attached approximately in the center in the longitudinal direction, has one end slidably attached to the slide rope 36 via a slide ring 40, and the other end attached to the other support. Height adjustment rope 32 provided in a loop shape at 6
The wires are tied directly to each other as nearly horizontally as possible.

In such a configuration, the direction indicating member 35 is tilted to instruct the direction in which the ball 38 should be hit with the slide rope 36 attached thereto serving as a serve, and the ball 38 follows this slide rope 3.
Only when the ball is hit in the direction provided by the ball 6, the vibration (reciprocating damped vibration) quickly subsides, and the feel of the ball is close to that of hitting the original ball. On the other hand, as the direction in which the ball 38 is hit deviates from the direction of this slide rope 36, the ball 38
8 begins to rotate using both ends of the string 39 as supports, and it takes a long time to come to rest, and the feel of the ball at impact is also significantly different from the original, and practice results are constantly being fed back to the practitioner. That will happen. When changing the direction of the serve depending on the height difference between practitioners, this can be easily done by changing the inclination angle of the direction support member 35, and the height of the ball 38 can be adjusted using the height adjustment rope 32. , 33 in a loop shape through the guide members 30, . . . , 31, .
