Description

Tennis Ball Trainer {Tennis Ball Trainer}

The present invention relates to a tennis ball exerciser for repeated tennis ball hitting exercises.

The present invention relates to a tennis ball exerciser (Application No. 10-2021-0092733), and more particularly, to a tennis ball exerciser used to repeatedly exercise tennis ball hitting by hitting a tennis ball connected to an elastic line fixed to the floor, It is convenient to learn or continuously exercise the tennis ball exercise, is simple to mount and manage, and also makes it easy to store and use the tennis ball exerciser, which is necessary for users who exercise the tennis ball.

In the old tennis ball exerciser (Application No. 10-2021-0092733), the line is often broken and twisted due to the rotation and friction of the ball, and when a tennis ball is hit, the movement of the rotating arrival ring riding the low-elasticity line is not constant, The movement of the tennis ball after rebound is also not constant, so it is difficult to hit, and it is difficult to store and manage the ball and line, and there are difficulties due to many restrictions in its use and installation. In particular, we present a correct tennis ball exerciser so that you can practice hitting a tennis ball in a small space and can easily install and remove it from time to time.

The elastic elastic string (4) does not get tangled well due to the inverse proportion of the thickness and length, and the constant activity environment of the tennis ball (0) affects the elastic elasticity of the string, thickness, length, material,

It is solved by creating a combination of mold ring and rotating pulley, and the material is light, smooth, and highly elastic, high elastic string is used, but it is not limited to this, and any other high elastic elastic string, which is light, smooth, and has high elasticity, does not matter. A little slippery oil coating on the surface makes for a nicer environment.

As for the first rotational arrival (10) and the second rotational arrival (20), it is sufficient if one rotation has no effect on the other.

The material of the low elasticity line (5) of the second fastening part is generally a slightly stiff, light and smooth low elasticity line that is smooth like fishing line and can prevent twisting and tying, but is not limited to this. It doesn't matter if you reduce the elastic elasticity that can prevent twisting and tying.

The first ring mark and the second ring mark connect to both ends of the low elastic elastic string, are not smaller than the second rotational lower ring 20-2 passing through the low elastic elastic string, and the second rotational lower ring 20 -2) It is a mark that limits the movement.

The first high elasticity line (7-1) and the second high elasticity line (7-2) are connected to both ends of the ring marks (6-1) (6-2) at both ends of the low elasticity line (5). , It is devised to compensate for the disadvantages of only the low elastic elastic string (5), and the second rotational arrival (20) lower ring (20-2) can be used stably by moving constantly along the low elastic elastic string (5) , A light, tough, and highly elastic string is used, but it is not limited thereto, and any other light, tough, and highly elastic string can be used.

The first tubular cloth loop (8-1). The second tube-type cloth ring 8-2 may be made of a soft and tough material that can be easily pierced even if a pin or nail is stabbed in any part.

The first pin 9-1 and the second pin 9-2 use pins or screws, but are not limited thereto and other types of means that can be fixed to the floor may be used.

When the high elastic elastic string (4), the second rotation arrives, and the low elastic elastic string is pulled, the

molded rings (1-2)(2-1)(2-2)(3-1)(3-2)(4-1)(4-2) and rotating abutment rings (10-1)(10- 2) (20-1) (20-2), the low elastic elastic strings (5) contact each other and are connected, and when they are released, they can be free from each other in all rings, so that all elastic strings twisted by the rotation of the tennis ball (0) may be less affected.

When the tennis ball (0) is hit, the lower ring (20-2) at the second rotation reaches the range between the ring marks (6-1) and ring marks (6-2) at both ends of the low-stretch elastic string (5) that was located before hitting. , and when the tennis ball (0) is hit from the center to the left, the lower ring (20-2) following the second rotation follows the tennis ball (0) at the point before hitting, and the string (5) with low elasticity It rides and moves to the left, and stops in the direction in which the tennis ball (0) flew, and the tennis ball (0), which rebounded from the stop, always returns toward the user who hit it. In addition, when the tennis ball (0) is hit from the center to the right, the lower ring (20-2) of the second rotation follows the tennis ball (0) from the position before the hit and moves to the right along the elastic string (5). As it moves, the tennis ball (0) stops in the direction in which it flew, and the tennis ball (0) that rebounds from the stopped position always returns toward the user who hit it, and the returned tennis ball (0) is hit again to repeat and continue. You can exercise through movement.

It further includes a cylindrical storage container (a) equipped with a string loop (c), the top is open and there are four grooves (e) symmetrically recessed at the bottom edge, and the open top of the storage container (a) Some are cut in an inverted triangle shape from the upper side to the lower side, make a droplet-shaped hole (b) asymmetrical at the bottom of the inverted triangle, and pass through holes (d) and holes (d1) on both sides of the upper part of the body (c) ), insert the ball (0) into the storage barrel (a), take the connected line out of the storage barrel (a) through the droplet-shaped hole (b), and connect all the connected lines to the cylinder of the storage barrel (a) It is wound outside, and the end of the string is put back into the storage cylinder (a) through the droplet-shaped hole (b) to fix it, and the string loop (c) is wound on the outside of the cylinder of the storage cylinder (a)-(1) ,(2),(3),(4), 1st rotation lead, 2nd rotation lead, 1st ring mark, 2nd ring mark, 1st high elastic cord, 2nd high elastic cord, 1st tube By wrapping the second tube-shaped fabric loop and the second tube-shaped fabric loop, it is fixed once more to the bottom edge groove (e) of the storage container (a), and the hole (d) on both sides of the upper body and the string loop (c) of the hole (d1) You can hang it on the handle of your tennis racquet for easy storage and use. The waterdrop-shaped hole is always closed, but it is a structure that allows easy entry and exit of thin strings or threads.
