Abstract

PROBLEM TO BE SOLVED: To attain miniaturization, to reduce weight and to kick/hit out a ball similarly to real one by winding a non-extension rope around a drum within a case, giving energizing force in the direction of winding and taking the rope to the drum and fixing a ball through the dawn out rope. SOLUTION: At the time of training kick, a case 1 is grasped by one hand by putting the hand through a grasping string 25, to pull out the non-extension rope 17 by the degree of making a soccer ball 23 approach the feet of a practicing player. At the time of kicking the ball forward then, the rope 17 is pulled out corresponding to the flying out. At this time, the drum 3 is rotated within the case 1 to wind and fastening a main spring 6 around a center shaft 2. In a state where the extension of an extension rope 21 is maximized and large spring force is accumulated, the ball 23 is rapidly pulled back in an original direction corresponding to the spring force. When the ball is kicked out upward, as it is pulled back while keeping the component of going-up force, it is raised high and returns to the training player.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training tool for ball games such as soccer.

[0002]

2. Description of the Related Art As a soccer practice tool, a non-stretchable rope is wound around a rotating drum housed in a case, and a spring force is applied by a spiral spring to wind the rope. It is known that a fitted soccer ball is attached.

In the above-mentioned soccer practice tool, when the practitioner himself holds the case or attaches it to a fixed object to kick the ball, the rope attached to the ball is pulled out and at the same time the mainspring spring is tightened.

When the flight force of the ball decreases and the spring force of the mainspring increases, the rope is wound around the drum by the spring force, and the ball is pulled back to its original position.

[0005]

In order to repeat the practice of kicking a ball, it is necessary to pull back the kicked ball quickly and strongly. Therefore, according to the above-described practice tool, the spring force of the mainspring is considerably increased. There is a need to. Therefore, it is necessary to use a power spring having a strong spring force, which causes a problem that the training tool becomes large and the cost becomes high. Also, because of the strong spring force, the kicking force is diminished, giving a feeling different from when the ball is actually kicked.

Therefore, according to the present invention, by separating the action of winding the rope from the action of pulling back the ball, the spring force is reduced as a winding spring for winding to achieve miniaturization and cost reduction. The purpose is to be able to kick or launch close.

[0007]

In order to achieve the above object, the present invention winds a non-stretchable rope around a drum rotatably housed in a case, and winds the non-stretchable rope around the drum. A biasing force is applied in the taking direction, and a ball is attached to the non-stretchable rope pulled out from the case via the stretchable rope.

According to the above construction, when the ball is kicked or hit and the non-stretchable rope is pulled out to the maximum extent,
The elastic rope is then stretched. The ball is pulled back by the elastic force associated with the extension of the stretchable rope, and the pulled-out non-stretchable rope is rewound by the biasing force applied to the drum.

In addition to the above structure, a stopper piece for preventing rotation of the drum may be provided in the case, and the operation portion of the stopper piece may be exposed to the outside of the case. In this case, when the non-stretchable rope is pulled out by a fixed length and the stopper piece is operated to lock the drum, the pull-out amount of the non-stretchable rope is limited. Therefore, when the ball is kicked, the pull-out limit of the non-stretchable rope is immediately reached, and the stretchable rope is then extended with a large force, so that the ball is rapidly and strongly pulled back.

By adopting a construction in which the above-mentioned stretchable rope is connected to the tip of the non-stretchable rope pulled out from the pull-out opening of the case through a twisting back tool, the rope is twisted even if practice is repeated. It doesn't take.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The embodiment shown in FIGS. 1 to 3 is a soccer practice tool in which a central shaft 2 is provided inside a flat spherical case 1, and a drum 3 is rotatably attached to the central shaft 2.

The drum 3 has a center hole of a body plate 5 for supporting the body 4 inserted through the center shaft 2.
Insert the spring spring 6 inside from the open surface facing
The inner end of the main spring 6 is hooked on the central shaft 2, and
Hang the outer end on the body 4.

After the mainspring 6 is housed, the open surface is closed by a disk-shaped closing plate 7. The closing plate 7 is integrally bonded to the body 4, and the central shaft 2 is inserted into the central hole of the closing plate 7. As shown in FIG. 3, a large number of locking claws 9 are formed at regular intervals on the outer peripheral edge 8 of the outer surface of the closing plate 7.

A stopper piece 1 is provided in the diametrical direction of the outer peripheral edge 8.
1 is slidable along. This stopper piece 11
Are supported by guides 12 formed on the inner surface of the case 1. Further, on the surface of the stopper piece 11 facing the closing plate 7, there is formed a projection 13 which is fitted and locked in a space between the locking claws 9. An operation button 14 is provided on the opposite surface of the protrusion 13 and is exposed to the outside through a hole 15 of the case 1.

By operating the operation button 14 from the outside and sliding the stopper piece 11, the projection 13 can be engaged with and disengaged from the locking claw 9.

Collars 16 are provided on both sides of the outer peripheral surface of the body 4, and a non-stretchable rope 17 is wound between the collars 16. As shown in FIG. 2, the inner end of the rope 17 is locked to the body 4, and is wound in the same direction as the mainspring 6 when viewed from the center axis 2. The tip of the rope 17 is pulled out from the pull-out port 18 of the case 1. The length of the non-stretchable rope 17 is appropriately determined, but is about 180 cm, for example.

A stretchable rope 21 is connected to a tip end of the non-stretchable rope 17 pulled out from the pull-out port 18 of the case 1 via a twisting back tool 19. The elastic rope 21 is made of a rubber cord, and has a natural length of about 30 cm and a maximum length of about 50 cm.

The soccer ball 23 is housed in the net bag 22, and the opening of the net bag 22 is squeezed and passed through the distal end portion of the elastic rope 21 and tied with the binding tool 20. The net bag 22 may be omitted and the tip of the rope 21 may be directly fixed to the soccer ball 23.

In addition, around the above-mentioned twisting-back tool 19, protective sleeves 24 and 2 made of sponge which are separated into upper and lower parts.
4'is covered to prevent the metallic twisting tool 19 from directly hitting the face or the like. Further, the grip string 25 is attached to the case 1. The protective sleeves 24, 24 'are separated from each other so as not to interfere with the operation of the twisting tool 19.

The soccer practice tool of the embodiment is as described above, and when practicing a kick using this,
The case 1 is grasped by passing one hand through the grasping cord 25, and the non-stretchable rope 17 is pulled out so that the soccer ball 23 approaches the foot of the practitioner 26 (see FIG. 4A). At this time, the pull-out length of the non-stretchable rope 17 is X, and the length of the stretchable rope 21 is Y.

From this state, when the ball 23 is kicked forward as shown by an arrow A in FIG. 4 (b), the non-stretchable rope 17 is pulled out in accordance with the protrusion of the ball 23. At this time, inside the case 1, the drum 3 rotates and the mainspring 6 is wound around the central axis 2.

When the non-stretchable rope 17 is pulled out to the maximum length (X + a), the stretchable rope 21 then elastically expands to Y + b (see FIG. 4 (b)).

When the non-stretchable rope 17 is pulled out, the spring force of the power spring 6 acting on the non-stretchable rope 17 is small. Therefore, the stretchable rope 21 does not substantially extend until it is pulled out to the maximum.

In a state where the extension of the elastic rope 21 reaches the maximum and a large elastic force is accumulated, the ball 23 is suddenly pulled back in accordance with the elastic force (see arrow B) and is pulled back in the original direction. . At this time, the spring spring 6 inside the case 1 does not have a force enough to positively pull back the ball 23, and the spring force exclusively rewinds the non-stretchable rope 17 pulled out to X + a.

In this way, the ball 23 is pulled back by the elastic force of the elastic rope 21, but when it is kicked upward, it is pulled back while maintaining the upward force component. Therefore, the chain line in FIG. And, as shown by the chain double-dashed line, go up and go back to the trainee 26. The degree to which the ball 23 rises up changes depending on the kicking angle, and the momentum of the ball 23 upon returning also changes according to the kicking force.

Therefore, when the returning ball 23 is to be kicked by the leg again, it is kicked at a low angle, and when the heading is to be kicked, it is kicked at a high angle.

In this way, not only the practice of kicking the ball 23 forward, but the practice of imagining the returning ball as the ball kicked back from the opponent can be repeated.

In this case, when kicking back or heading, the non-stretchable rope 17 is wound into the case 1 at the same time when the ball 23 returns, so it does not interfere with kicking or heading.

Further, in order to limit the pull-out length of the non-stretchable rope 17, the initial pull-out length (eg, FIG. 4).
Operate the operation button 14 in the state of (a) length X),
The stopper piece 11 is locked to the locking claw 9 of the closing plate 7.
Then, when the ball 23 is kicked, the non-stretchable rope 17 does not extend beyond X, so the ball 23 is kicked out at a high angle,
Moreover, since the kicking force applied is pulled back while being sufficiently large, the practitioner 26 instantly returns to the practitioner 26 at a vigorous and high angle. Therefore, you can practice dealing with the ball kicked back high at the counter.

If, for example, a tennis ball is used as the ball and the case 1 is attached to an appropriate fixed object, it is possible to practice hitting the ball with a racket and hitting the returned ball back. It can also be used as a volleyball practice tool.

[0031]

As described above, according to the present invention, since the force for pulling back the ball is obtained by the elastic force of the elastic rope, the spring force of the mainspring in the case is small enough to rewind the non-elastic rope. Power is enough. Therefore, since the spring force of the mainspring does not affect the kicking force or the hitting force applied to the ball, the ball can be naturally kicked or hit.

Further, since the mainspring has only to have a small spring force, it has a merit that the case is small and the cost is low.
