Abstract

A single-person pitching training apparatus is composed of a frame part, a catching part, a target part, and a returning part. The muzzle part is made of a mesh net material to buffer kinetic energy with low noise. The recovery part has an upper part generating a rotational force to a ball and a gentle slope for guiding to the ground smoothly. The present invention generates almost no noise when pitching the ball, thereby being able to perform indoor pitching training.

Description

Pitching training device

The present invention is a ball thrown by a pitcher (pitcher; pitcher) to practice the throwing (pitting ball) throwing a ball, such as a baseball ball, handball ball, softball ball to the desired position alone The invention relates to an apparatus for catching and returning a ball. More specifically, the present invention relates to a ball throwing exerciser or a ball throwing exercise device having a mechanism for quietly throwing a ball and recovering it without using power.

In general, when one person does not have a lot of balls to practice throwing ball, the wall or elastic bouncing is used to recover the thrown ball. If you have a lot of balls, you can throw them all at once near the catching area. In addition, since noise is generated during catching, it is difficult to exercise indoors and to exercise outdoors.

In order to practice throwing indoors, I would like to suggest a way to throw the ball thrown by the thrower with low noise.

I would like to present a way to return the ball to the thrower without an external power source such as electricity.

In order to muzzle with low noise, the first collision noise hit by the ball and the muzzle object and the second collision noise falling on the ground after the collision were reduced. In order to reduce the primary impact noise, a net-shaped loose net was used as a sphere, and the second collision noise with the ground when dropped after the sphere was a net, a fiber woven fabric, or a non-woven fabric. ) Can be reduced.

In order to return the ball to the thrower, the potential energy of the ball was converted to the rotational force and kinetic energy in the direction of the ball at the location of the ball. The net made the ball fall to the ground after the ball was thrown, and the inclined surface was placed on the drop to give the ball a rolling force.

Since there is little noise when the ball is thrown, you can throw a ball indoors.

The ball is very easy to recover, so one person can throw a ball without a catcher.

Figure 1 is a side view of the device to show the ball and the trajectory of the ball in order to explain the interaction of the ball, catch. Target portion is an embodiment configured integrally on the upper portion of the recovery portion.
Fig. 2 is a front view of the apparatus viewed from the receiver side. It is an embodiment in which a recovery unit is located behind a loose net, which is a muzzle, and a target target unit for inducing a ball is integrated with the recovery unit.
3 is a view illustrating a structure in which the ball is rotated by being tilted at an inclination angle over the recovery part of the rear side while falling in the direction of gravity after being thrown into the net.
4 shows a printed target (Target) of the target unit integrally formed on the upper surface of the recovery unit, and a hook (outer hole, etc.) for installing the recovery unit in the frame.
5 is a product structure diagram of all parts classified by function.
6 is an embodiment of the structure in which the muzzle and the recovery part are integrally formed. In this case, the target part cannot be printed on the net, so it is located alone on the rear of the muzzle.

Ball games, such as baseball, softball and handball, require the training of the skill of throwing the ball to the desired position. Figure 1 is a conceptual diagram illustrating a training situation of throwing the ball to the front and an embodiment of the present invention as an embodiment of a baseball.

In FIG. 1, the thrower threw the baseball 40 in the direction of the target portion 30, 34, which is the device direction 41. The baseball hits the baggy net 20, which is the primary muzzle chain, and is muzzled and stopped with low noise. In the process of loosening, the loose netting envelops the baseball and is pushed in the direction of Target (34). This muzzle method is similar to the intermediate net of a golf practice range. Coarse meshes rather than dense fibrous fabrics should be used to minimize radiation noise when colliding with balls. In the muzzle process, the kinetic energy falls from the position pushed back from the original position of the mesh and falls down 42 in the direction of gravity, and the baseball strikes the inclined angle with the upper portion 30 of the fiber recovery portion. The fiber of the recovery part is also slightly concave, and the baseball is secondary to the ball, and in this process, the rotational force 43 is generated in the baseball. Since the inclined surface of the recovery portion is toward the thrower, the rotation of the baseball always rolls the ball toward the thrower. Behind the net you can put a target so that the thrower can mark the direction of the ball. This target can be installed as a separate item, but printing on the inclined surface of the recovery part can reduce the number of parts. The recovery unit 30 breaks the inclination in the middle to induce the gentle tilting unit 35 so that the rolling baseball meets the horizontal ground smoothly. It is possible to fold the inclination by placing the hooks 32 on both sides of the middle of the recovery portion in the form of cloth.

When throwing a hard baseball ball or the like as described above, the noise of the muzzle can be almost eliminated, and the thrown ball can be smoothly recovered to the thrower. With this device, you can quietly throw drills indoors and outdoors.

Claims (6)

In constructing a single-use throwing exerciser composed of a frame part, a muzzle part, a recovery part, and a target part, a single-person throwing exercise characterized in that the ball is quietly pitched by the muzzle part and the ball is rotated by the recovery part to be returned to the receiver. Device. The method of claim 1, wherein the recovery portion is characterized in that it consists of two stages of inclination to the lower gentle gentle portion that meets the top and the horizontal bottom surface generating a rotational force to the ball falling from the muzzle. In Claim 2, it can be comprised in one piece or two separate objects in order to give the inclination of a collection part in two steps. The recovery unit of claim 2 reduces the impact noise of the lesson by using a soft material in the form of a sheet such as a net, a fiber material, a rubber material, and a vinyl material. In Claim 1, a collection | recovery part can be integrated with a target part (FIG. 1 Embodiment), and a muzzle part and a collection | recovery part can be comprised integrally (FIG. 6 Embodiment).
The muzzle portion of claim 1 is made of a mesh-type net material, is installed in a loose state without pulling from the outside to surround the ball without generating a reaction force when colliding with the ball, it is concave and deformed to stop quietly.
