For this reason, it is necessary for the assistant to frequently approach the knocker in order to hand the ball, and there was a safety concern when the assistant was a child. In addition, it was necessary for the knocker and the assistant to breathe together, and there was a lot of trouble.

      Accordingly, a main object of the present invention is to provide a shuttlecock shoulder type ball dispenser in which a hander is not required and a knocker can take out balls one by one from a cylinder.

The second object of the present invention is to eliminate the need for a handing assistant and to place a ball-out device on the shoulder so that a coach such as a knocker always takes out the balls one by one and quickly changes the course. An object of the present invention is to provide a shuttlecock shoulder type ball thrower that can be hit while.

      A third object of the present invention is to provide the above-mentioned shoulder type ball thrower having a structure that prevents the shuttlecock blades from being damaged when the ball is thrown out and is not injured when the shuttlecock is inserted.

A fourth object of the present invention is to provide a shoulder-type ball thrower that can be adjusted to the number of balls that matches the level of the practitioner at the time of pitching using the function of stretchable kato.

      A fifth object of the present invention is to provide a shoulder-type ball pouch that can be stored in a small and compact manner during storage because a gymnasium or the like is narrow and small relative to the size of the gymnasium.

      A sixth object of the present invention is to provide a shoulder-type ball discharger which has a loss prevention effect that prevents the shuttlecock from being exposed even if the cylinder is left and right and up and down by providing caps at both ends of the opening. is there.

The seventh object of the present invention is to prevent injury by covering the entire cylinder so that fingers are not pinched by the bellows-like stretchable barrel, and provided with shoulder straps with adjustment functions at both ends. An object of the present invention is to provide a shoulder-type ball pouch that can be adjusted according to the user's physique and can be adjusted and fitted to the user's sitting height.

Japanese Patent Laid-Open No. 6-046758 JP-A-9-117539

In the conventional practice technique, balls (shuttle cocks) are handed to the knocker one by one. In order to solve this problem, there was a badminton practice ball-out device, but the shaft was fixed and there was a problem in movement, storage and compactness.

In the conventional badminton practitioner, the shape of the cylinder is fixed, and there is a problem in the functionality of adjusting the number of balls.

In a conventional badminton practitioner, the assistant frequently goes near the pouch because the ball (shuttlecock) is inserted into a pouch installed near the knocker's coach. In particular, there was a risk that a knocker's racket could be hit, especially when young children such as elementary school students were assistants.

A conventional badminton practitioner is a relatively expensive practice device that can only be purchased by a club or the like that is organized by number of people, and is difficult to purchase individually. In addition, the number of units purchased is limited due to the space required for installation and storage.

When practicing badminton as a competition, a large number of shuttles are used. In order to store this, in many cases, a commercially available plastic case is used, or it is returned to the cylinder at the time of purchasing the shuttle, and a box in which the cylinder is contained is used. Therefore, there is a problem in storing the shuttlecock only with the badminton practice ball thrower that has a limited number of conventional purchases.

When practicing badminton as a competition, if you are practicing an advanced player or a practitioner who puts out a lot of shuttles with a single knock, there is a voice that 25 to 30 balls are not enough, and the upper limit of the number of balls There was a problem.

The problem to be solved by the present invention is to eliminate the drawbacks of the above conventional example, have openings at both ends, and have a cavity larger than the maximum length of shuttlecock blades hanging from the shoulder of the user to the waist. The cylindrical body is made to be stretchable and towable, and the head of the shuttlecock that has dropped the hollow portion of the cylindrical body is exposed to the lower end opening of the cylindrical body, and the blades An outlet member for locking the distal end portion is provided to eliminate the need for handing.

It is further characterized in that a curved surface is formed of soft felt on the inner surface of the minimum warp portion of the shrinkage take-out port member of the stretchable towable cylinder.

Furthermore, in order to achieve the fourth and fifth objects, the present invention has a shape of a stretchable towable tubular body mainly by making the tubular body bellows-like. This makes it possible to adjust the number of balls according to the level of the practitioner, to adjust the sitting height of the user, to fit the body, and to be stored compactly when stored.

      In order to achieve the sixth object, according to the present invention, by providing caps at the openings at both ends, the cylinder can be freely moved without being exposed from the cylinder even when moving or storing the shuttle. It is characterized by reduced damage and loss, and by using a shoulder-type shuttlecock storage cylinder, it is now possible to use a ball-out device that could only be used by groups, etc. It is characterized in that all users can use it conveniently when moving or storing it.

In order to achieve the seventh object, by providing a cover that wraps the entire bellows-shaped stretchable tube body, a risk prevention effect of pinching fingers, etc. during expansion and contraction, and shoulders with adjustment functions at both ends of the tube body The band is provided so that the user can freely move on the shoulder and adjust and fit the user's sitting height.

In order to achieve the eighth object, it is possible to provide a shuttlecock storage cylinder that can be used easily and easily even by fashionable and fashionable individuals by using a design cover that matches the needs of the user. And

In order to achieve the ninth object, by providing a dedicated attachment part that can fix the three practice devices of the present invention, a triple shoulder-type badminton practice ball thrower can be formed at a time. It is characterized by being able to cope with practice and practitioners that require ball-out.

The present invention can be easily obtained by simply pulling out the shuttlecock protruding from the tip of the take-out port of the ball discharger, and the shuttlecock in the subsequent stage descends by its own weight in the hollow cylinder, Can be taken out one by one continuously. Therefore, knock practice etc. can be performed very efficiently.

      In the present invention, since the ball thrower and the knocker are integrated, it becomes easy to grasp the state and position of children picking up and replenishing the shuttle. Since it is behind the knocker even when it comes close, it does not coincide with the track of the racket, and it is possible to safely replenish the ball dispenser with many balls at once. Therefore, safety during practice can be maintained.

By using a soft material for the inner surface of the catching portion of the takeout member, the frictional resistance of the shuttlecock during pulling is reduced and damage to the blades is reduced.

By making the shape of the cylindrical body into a stretchable and accordion bellows shape, it is possible to adjust the number of balls according to the level of the practitioner and to adjust and fit the sitting height of the user.

By providing caps at both ends of the opening, the shuttlecock is not exposed even if the cylinder is freely adjustable, and there is no risk of loss.

The entire tube is covered so that fingers are not caught between the stretchable kato tube, and shoulder bands with adjustment functions are provided at both ends. As a result, the user can place the ball-out device on the shoulder and can move safely and freely. Furthermore, it becomes possible to easily change the ball course during practice.

In addition to the above, even a narrow space such as a physical education warehouse or home can be compactly accommodated if it is reduced to the minimum width. It can also be used as a shuttlecock moving / storage cylinder by inserting the shuttle and closing the caps at both ends. Because the cover has an adjustable shoulder band, there is no worry of the blades being damaged or lost even when moving slightly, and it is convenient, fashionable and easy for individuals to use and carry.

In addition, by using a design cover that matches the needs of users, etc., it becomes a fashionable and stylish shuttlecock storage cylinder.

To provide a shuttlecock with more than the above-mentioned ball number adjustment at a time, a dedicated mounting part that can fix three of the practice equipment of the present invention is provided, so that a triple-shoulder-type badminton practice ball-out device is obtained. , You will be able to get the number of balls 3 times the original number.
