BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training device used for pitching and batting training of a baseball player, and in particular, trains a muscular strength required for pitching and batting in a well-balanced manner and corrects a throwing posture and a batting posture. The present invention relates to a baseball training practice device suitable for performing.

[0002]

2. Description of the Related Art Conventionally, during training of batting, a mascot bat body heavier than a normal bat body or a weight is attached to the tip of the bat body to perform a batting operation. It is also conceivable to fix one end side of an elastic body such as a rubber tube or a spring to a column or the like, and lock the other end side of the elastic body to the tip side of the bat body to perform the batting operation. In addition, during training in pitching, the towel is gripped and a pitching operation is performed so that the towel receives air resistance and becomes a load, and one end side of an elastic body such as a rubber tube or a spring is fixed to a pillar or the like. Training such as holding the other end and then performing a pitching motion is also conceivable.

[0003]

In the conventional batting training using a mascot bat body and weights, the muscular strength required for supporting and braking the bat body is used, and the muscular strength required for the swing of the bat body is pure. It was difficult to train, and it was difficult to learn the correct batting form because it had a different weight feeling from the bat body that is usually used. Further, if the batting training is performed using an elastic body, the restoring force of the elastic body changes the load applied to the tip of the bat body during the swing of the bat body, which makes it difficult to perform a correct bat body swing. This was also difficult to learn the correct batting form.

Pitching training using air resistance with a towel or the like does not break the pitching foam, but its resistance to load is small, so that it is not effective for muscle training. Also, if you try to perform pitching training using an elastic body, the restoring force of the elastic body changes the load applied to the shoulder and elbow, which does not occur in a series of movements during normal pitching, It was difficult to learn the correct pitching form, and in particular, it caused the shoulders and elbows to be injured by repeating training with the wrong pitching form for developing children and students.

The present invention has been made in view of the above problems of the prior art, and one of the objects thereof is that it can be manufactured at a low cost with an extremely simple structure, is easy to use, and is a correct foam for batting and pitching. It is an object of the present invention to provide a baseball training practice device which has an excellent effect of fully wearing and which has a practicability in which the whole body muscular strength necessary for batting and pitching movements can be well balanced, thereby eliminating breakdown due to training. .
Another object of the present invention is to use the device in a small space by reducing the number of parts of the device and making the assembly simple and compact, and can be easily carried, and can be used indoors in the snow or rainy weather. It is to provide a baseball training practice device.

It is accommodated in a state of being drawn into the inside of the unit 6. Then, the remaining one-fifth portion is pulled out to the outside of the cylindrical body 26 and connected to the tip portion of the bat body B described later. This makes it possible to sufficiently secure a necessary length corresponding to the rotational movement when the bat body B is swung during practicing batting. That is, by swinging with a load body such as a moving pulley or a weight suspended from the U-shaped bottom portion of the U-shaped rope, the vertical motion width of the load body during the rotational movement of the bat body swing is directly A shorter vertical movement width is required as compared with the case of being fixed to the end of the cord, and therefore the length of the tubular body 26 can be shortened accordingly, and concretely, the installation and construction of the device can be performed easily and in a short time. Further, the material cost can be kept low. Further, it becomes possible to easily assemble the device and replace the weight 22 without using a separate step.

Both of them are pulled up vertically in the tubular body 26, and similarly, the tow is released to lower these load bodies. Both the movable pulley 20 and the weight 22 have an outer diameter size smaller than the diameter of the tubular body 26 housed and arranged in the tubular body 26, and are always placed in the tubular body 26 and move up and down at the same time to the outside. Does not come out. Weight 22
Is replaceable so that the weight can be selected according to the physical strength of the practitioner.

In FIGS. 1 to 3, a connecting device 16 is provided on the other end side of the cord body 12 extended from the cylindrical body 26 to the outside, and the connecting device 16 is the other end of the cord body 12. It is a connecting means for connecting the side to the tip of the bat body B held by a person. In the embodiment, the connecting device 16 includes a detachable fixing tool 28 detachably attached to the head portion H of the bat body B, and a direct connection cord connecting the detachable fixing tool 28 and the other end of the cord body 12. And a section 30. In the present embodiment, the attachment / detachment fixture 28 includes a hollow inverted bowl-shaped cap body 60 having a mounting hollow portion 61 that is fitted into the head portion H of the bat body B in an inverted state. The cap body 60 is made of synthetic resin and has an opening into which the head portion H of the bat body B is inserted. Inside the cap body 60, a braking cylinder 62 made of synthetic resin and having a short hollow cylindrical shape is arranged.

In the figure, the inner diameter of the braking cylinder 62 is set to be slightly longer than the diameter of the head portion H of the commercially available bat body B, for example, so that the bat body B can be inserted and removed. . Further, a bolt member 64 is provided on the diagonal line near the opening end side of the cap body 60 so as to penetrate the cap body 60 and the braking cylinder 62. Thereby, the bat body B is inserted into the mounting hollow portion 61 of the cap body 60,
By tightening the pair of bolt members 64 from both sides in this state, the bat body B is reliably connected to the cap body 60. In addition, a ring-shaped fixture 66 rotatably connected to the cap body 60 is fixed to the inverted top of the cap body 60, whereby the bat body B is searched for via the connecting device 16. It is connected to the other end of the strip 12. In the embodiment, the fixture 66 is the direct connection cord connecting portion 30.

The fixture 66 of the connecting device 16 and the connecting device 1
By rotatably providing the joint portion with the cap body 60 which is 6, when the bat body B is shaken while being inserted and fixed in the coupling device 16,
The head portion of the bat body B rotates about 180 degrees around the axis of the bat body due to the rotation of the practitioner's arm and the twisting motion of the arm, and the cord body locked to the connecting device 16 follows the rotation. When the twisting operation of 12 is performed, an extra load of twisting rotation is applied to the head portion of the bat body B, and further, the cord 1
Although this results in accelerating the breakage of No. 2, in the present embodiment, since the fixing tool 66 is rotatable with respect to the connecting device 16, the cord body 12 can be smoothly pulled out without being twisted, and the bat body can be pulled out. The head portion of B can be strengthened by a correct batting form without applying an extra load of twisting rotation.

In this embodiment, FIGS.
As shown in FIG. 7, a striking body support mechanism 38 used during striking practice is provided near the practitioner. The striking body support mechanism 38 is a striking body 32 provided in the vicinity of the swing trajectory of the bat body B, and a spring that fixes the striking body 32 to the upper portion and is capable of restoring the position of the striking body 32 against the striking by the bat body B. It includes a member 34 and a stand post 36 for vertically supporting the spring member 34. In the figure, the practitioner stands in a batting posture, grasps the bat body B, takes it back, and swings the bat body B over the pedestal 76 and the pedestal 76 directly below the swing path of the bat body B. A hollow cylindrical support post 78 that is supported and fixed upright;
Is provided with a stand post 36. The spring member 34 is vertically supported by being supported by the stand post 36, and the striking body 32 is fixedly supported so as to be positioned at the upper end portion of the spring member 34 and on the swing track of the practitioner. A rod-shaped spring support 70 is vertically connected and fixed to the lower end of the spring member 34. The spring support body 70 is inserted in the hollow portion of the support post 78 so as to be vertically movable. A plurality of lock holes are formed in the support post 78 and the spring support 70 in the height direction with the same pitch width. Then, the positioning pin 74 is fixed to the tip of the chain 72 connected to the support body 70, and the positioning pin 74 is passed through the lock hole at the required height position of the support body 70 with respect to the support post 78, thereby the spring member. The height position of the impacting body 32 at the upper end of 34 can be adjusted.

The spring member 34 is formed of, for example, a helical spring which has strength and can be held upright at all times in a state where the striking body 32 is supported and fixed to the upper end, and the striking body 32 is struck by the bat body B. As shown in FIG. 3, the restoring means is capable of immediately restoring the shape and restoring the original position even in the fallen state. In the embodiment, the helical springs are arranged vertically and are held at all times or in an upright state when restored.

The hitting body 32 is made of, for example, a sphere, and is preferably made by directly bonding or joining real hard balls or soft balls to the spring member 34. Further, it does not have to be a sphere like a ball, and may have any shape and material. Also, the connection may be fixed by any joining means. The striker 32 of the striker support mechanism 38 adjusts the height of the ball to a height near the waist, which the practitioner is not good at, and arranges the striker 32, so that the practitioner can wear a swing suitable for the ball having a weakness. You will be able to apply it, and at the same time you will be able to train the muscular strength necessary for the swing that strikes the ball.

According to the practice device 10 of this embodiment, as shown in FIGS. 2 and 3, the practitioner moves from the position of the head H of the bat body B shown in FIG. 2 to the head of the bat body B shown in FIG. When the hitting body 32 is swung to pass through the arrow S to the position H, the connecting device 16 locked to the bat body B inevitably passes on the arrow S as well as the bat B. And move. As a result, the cord 12 locked by the connecting device 16 is pulled out from the inside of the tubular body 26. At this time, as shown in the figure, since the moving pulley 20 in which the weight 22 is connected is wound around the cord 12, the cord 22 is pulled out from the position of FIG. 3 by pulling out the cord 12. It is pulled up to the position. At this time, the gravitational load of the weight 22 is mainly applied to the cord 12 via the moving pulley 20.

When the U-shaped portion of the cord is pulled up, the load applied to the cord body 12 such as a weight is merely a constant change in the potential energy of the load, and therefore the load itself does not change. During the swing, it always swings against a constant load. Therefore, the bat body is rotated with the same force, and the form can be learned without breaking the correct batting form. In addition, the muscular strength of the whole body required for the bat body swing can be well balanced, and since it is exercise with a constant force, it does not give a sudden load to the muscles and joints and causes physical damage of the practitioner. There is no.

In FIG. 2 and FIG. 3, the head H of the bat body B is swung so as to pass on the line of sight S and be launched from the side surface of the striking body 32. In the case of performing such a swing, A force is applied to the impacting body 32 so as to be directed obliquely upward. However, the striking body support mechanism 38 of the present embodiment has the spring member 34 that fixes the striking body 32.
Is fixed to the stand post 36 by the positioning pin 74, the impacting body 32 does not come off from the stand post 36 due to the impact. Further, as shown in FIG. 3, in the impacting body 32, the spring member 34 is largely bent so that the impact that has been driven in is released, and the impact is dispersed. Then, when the spring member 34 returns to its own state, the impacting body 32 can be driven again and can be continuously used.

In the present embodiment, in addition to the dynamic strengthening of the bat body during the swing, the bat body during the swing is further stopped, for example, in the vicinity of the striking body 32, and the state is maintained to maintain the muscular strength of the whole body. It is also possible to carry out training that brings out the effect of improving strength.

Further, as in the present embodiment, the cord 12 is hung from the constant pulley 18 into the tubular body 26 in a U-shape and the movable pulley 20 is wound around the cord 12, so that the cord 12 is extended to the outside. Although the load related to pulling the rope is about one half of the gravity load by the weight 22, the length of the cord 12 that can be accommodated in the tubular body 26 can be set long. As a result, it becomes possible to sufficiently secure the length of the cord required to follow the swing motion of the bat body B in the practice device 10 set to be small.

Next, the practice apparatus 100 according to the second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The same components as those of the first embodiment are designated by the same reference numerals. , The description is omitted. In the present embodiment, the training device 100 is the same as the first embodiment in that the training device 100 is composed of the cord 12, the gravity load mechanism 14, and the connecting device 16, but the connecting device 16 is the head portion of the bat body B.
