Description

The present invention relates to a baseball swing training device applied to a baseball bat for practice, and in particular, the moment of impact (impact) and actual hitting in the swing motion of the baseball bat for practice in order to cope with a fast pitcher ball. At the same time as practice to match the timing of the moment of hitting accurately, at the same time as strengthening the wrist power and increasing the power and swing speed, while confirming the hitting sound and swing trajectory from the perspective, of course, the batting attitude correction is of course, the degree of concentration to the hitting moment It is related with the baseball swing practice device which can raise.

In general, baseball players practice swing using a batting practice device that automatically hits a ball, or a method of hitting dozens of baseball bats on a fixed object.

In addition, baseball players practice a number of swings before entering a hit in order to keep the swing feeling efficient.

At that time, the players are actually practicing swing by picking up two or three bats at the same time depending on their individual abilities.

This is because people have the ability to remember momentary weight, so many batters tend to practice swinging in the same way as before before entering the bat.

However, when swing exercises are repeated in the above way, there are problems that the posture of the swing becomes unstable and that the person himself cannot directly use the perfect swing through repeated exercises while checking the balance of the swing point directly. there were.

Therefore, in the conventional baseball swing training device proposed as a method for solving such problems, a fixed weight body is installed at one end of the shaft and a grip member is installed at the other end, and these fixed weight body and grip It is composed of a moving weight body that generates a sound (striking sound) proportional to the impact force when it is collided with the fixed weight body while moving along the shaft by centrifugal force during the swing operation of the inter-member shaft.

However, such a conventional baseball swing training device not only makes it difficult to find the exact hit timing because the moving weight body collides with the fixed weight body quickly due to the action of gravity during the swing operation, but also at the impact moment and the actual hitting. Because the timing of the ball's hitting moment cannot be accurately matched, it is impossible to deal with a variety of pitcher balls and fast and fast straight balls, and it is impossible to increase wrist strength, power, and fast swing speed. There was a problem that the hitting rate and the long hitting power decreased.

Next, a second embodiment of the present invention will be described in detail with reference to FIGS. 5 to 8 of the accompanying drawings.

For reference, regarding the second embodiment of the present invention, the same components as those in the first embodiment are given the same names and the same reference numerals, and detailed descriptions thereof are omitted.

A baseball swing training device according to a second embodiment of the present invention includes a shaft (10), a fixed weight body (20) fixed to one side end of the shaft (10), and the other end of the shaft (10). A grip portion (30) coupled so as to be attachable and detachable, and a moving weight body (42) inserted into the shaft (10) and moved by centrifugal force along the shaft (10) during a swing operation. The moving weight body (42) is inserted into the shaft (10) between the fixed weight body (20) and the moving weight body (42) collides with the fixed weight body (20) by the swing speed. A resilient member (44) that applies a resilient force so as to give an accurate timing, and is inserted into the shaft (10) between the moving weight body (42) and the grip portion (30), and the moving weight body (42 ) Is inserted into the shaft (10) so as to be positioned between the stopper (46) and the moving weight body (42). Includes support moving weight body to increase the power (50).

At this time, on the outer peripheral side of the fixed weight body (20), while the impact moment and the trajectory can be confirmed visually, correction of the striking posture is, of course, a flasher (60) so as to increase the degree of concentration with respect to the striking moment. The flasher (60), which is connected so as to be attached and detached, is installed in a case and has an LED lamp that emits light to the outside, an impact detection sensor, and a timer that operates for a predetermined time by the impact detection sensor. It is preferable that the switching element is configured to be switched by the control of the timer and a battery that supplies power to the LED lamp through the switching element.

The grip portion (30) is formed with an insertion hole (32) on one side end side surface of the body so that the shaft (10) is inserted at a certain depth, and the inner periphery of the insertion hole (32) is formed. A male and female spiral surface (16) (34) is formed on the outer periphery of one side end of the shaft (10) so as to correspond to each other, and a grip portion is formed on the outer peripheral side end of the body. A fixing bolt (70) penetrating the grip portion (30) is installed so that the shaft (10) does not rotate or flow from (30).

In other words, the fixing bolt (70) is screwed so as to be depressed on one side of the grip portion (30), and its end is strongly bound to the outer periphery of the shaft (10).

The auxiliary moving weight body (50) is formed of a ring shape of any kind of heavy material selected from metal, wood, rubber and resin.

Next, operations and effects of the first and second embodiments of the present invention configured as described above will be described.

When the practitioner grasps the grip part (30) and takes a swinging posture, the moving weight body (42) grips along the shaft (10) by its own weight and the expansion force of the resilient member (44) as shown in FIG. Moved to the part (30) side.

At this time, when the bat is swung, the moving weight body (42) moves quickly along the shaft (10) toward the fixed weight body (20) side by its own weight and centrifugal force as shown in FIG. (42) and the fixed weight body (20), while the coil spring type resilient member (44) is pressurized (contracted) and the moving weight body (42) collides with the fixed weight body (20). A sound (battering sound) is generated.

The elastic member (44) applied here has a structure in which the pitch gradually becomes narrower from the one side end in contact with the moving weight body (42) to the other side end in contact with the fixed weight body (20). Therefore, it is possible to adjust the resilience (resistance) step by step according to the strength of the swing speed.

For example, if the centrifugal force is much larger than the elastic force of the elastic member (44), the moving weight body (42) strongly collides with the fixed weight body (20) at a high speed and generates a strong sound (battering sound). However, if the centrifugal force is a little larger than the elastic force, the moving weight body (42) will weakly collide with the fixed weight body (20) at a weak speed and generate a weak sound (battering sound). The sound (battering sound) proportional to the equal collision force is generated differently.

However, if the centrifugal force is smaller than the elastic force of the elastic member (44), the moving weight body (42) cannot reach the fixed weight body (20), so that no sound (striking sound) is generated.

The baseball swing training device can be adjusted according to the ability of the trainer by changing the weight of the moving weight body (42) and the auxiliary moving weight body (50) and the resilient member (44) having high resilience. So, it is possible to practice by matching the timing of impact moment in swing motion and the moment of impact in actual hit exactly, and in this actual battle repeated swing exercise, of course wrist strength strengthening, power and swing speed Increased efficiently.

That is, since the shaft (10) and the grip part (30) are screwed together so that they can be attached and detached as shown in FIG. 6, for example, after separating the shaft (10) from the grip part (30), the shaft (10) Additional auxiliary moving weight body (50) separately provided between the stopper (46) and moving weight body (42) on the rear side, or replacing the highly resilient spring member (44) Can be used as a swing exerciser that requires stronger power and faster swing speed, and such a swing exerciser can not only deal with a variety of ball pitches and fast straight balls in pitcher in actual battle, but also hit rate And long hitting power can be increased.

In addition, since the elastic force of the elastic member (44) is adjusted by adjusting the position of the stopper (46), the moving weight body (42) and the auxiliary moving weight body (50) depending on the swing posture and swing speed of the practitioner. The generation of different centrifugal forces depending on the moving speed, starting point, weight, swing trajectory, etc. of the vehicle is sufficiently supplemented.

On the other hand, since the luminous body (22) or the flasher (60) is attached to the outer periphery of the fixed weight body (20), not only the sound at the moment of impact (striking sound) but also daylight and nighttime during swing practice. While the impact moment and the trajectory are visually confirmed through the light generated from the body (22) or the flasher (60), the striking posture correction can of course increase the concentration with respect to the striking moment.
