Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention can be attached to a bat when practicing the swing form for hitting a hole with a bat, such as a golf club, baseball bat, or even a skateboard for Kateball. This invention relates to a swing training device used as a swing trainer.

<Prior Art> For example, improving the flight distance and directionality of a golfer's shot with a driver can be said to be of greatest interest to golfers. To send the ball straight towards the target,
Two conditions need to be met: ■Square swing ■Square impact.

With practice swings and trial shots, which are normally practiced, after a certain amount of practice, you will be able to recognize the trajectory of the swing and distinguish whether it is correct or not, but this is difficult for beginners, and it is difficult for advanced players to master the shape of the impact. Even an expert could only make an estimate based on the direction of the ball and the recognized swing trajectory based on test shots, and it was impossible to grasp the actual situation. In addition, the swing form of irons and putters, the swing form of baseball bats, and the main swing form of gateball Z'fA-t7 each have their own preferred swing trajectory and impact shape, but these are difficult to recognize during swing practice. is the same as for the driver shot above. Therefore, in order to accurately grasp the trajectory of the swing and the shape of the impact, there is no other suitable method than to record it with a video camera and replay it, or analyze it using a high-end training device. It was hoped that an application would be filed.

<Problems to be Solved by the Present Invention> The present invention aims to make it possible to separate and recognize the swing trajectory and impact shape when practicing swing form, such as swinging a golf club or a gateball stick. The purpose is to provide a swing training device for the purpose of.

<Means for Solving the Problems> The present invention includes a lighting display member in which two light emitting elements are fixed at a predetermined interval on the upper surface of one base, and a lighting display member that is used to strike the ball of a batting club used for swing practice. The base is made of fabric, felt, or synthetic material formed in a size that can be attached to the top of the head of a golf club or gateball stick, or the top of the meet point of a bat. Resin sheet 1 consists of a metal plate and a synthetic resin molded product. The light emitting elements include light emitting diodes (LEDs), visible light semiconductor lasers, electroluminescent elements (EL elements), small light bulbs, etc. The two light emitting elements emit light in red and yellow.

In addition to combinations of different luminescent colors such as red and green or yellow and green, it also includes combinations of the same color.

In addition, the mounting member for attaching the lighting display member to a hitting stick such as a club or bat must have the ability to be easily attached and detached, such as by attaching it with double-sided adhesive tape or Velcro fasteners, or by binding it with a rubber band or belt. is included.

The mounting position of the lighting display member is the part 1 of the batting club that hits the ball.
In other words, when playing a golf club or on the tee of a gate ball, the two light emitting elements are positioned in the line of sight of the practitioner looking at a perpendicular line to the plane touching the sweet spot through which the sweet spot of the club head passes. For baseball bats, the standard position is to position and install the two light emitting elements so that they are on a straight line that passes through the batting point and is parallel to a perpendicular line that is in contact with the batting point. , as long as it is on a straight line parallel to the above perpendicular line, there is no problem in practical use if the battery is slightly misaligned back and forth.In addition, a small battery may be stored in the base, or a battery with a large capacity may be stored in a battery tape. It may be stored and attached near the grip of the batting club, and connected to the light emitting element using an electric wire.In this case, the electric wire may be wrapped around the shaft or bat, and if necessary, adhesive tape or rubber bands may be used to ensure that it does not interfere with the swing. It will be fixed like this.

Note that a connection plug may be inserted into the electric wire connecting between the lighting display member and the battery tape, or a switch may be provided to turn on/off the light emitting element.

<Effect> Swing practice is performed with the two light emitting elements turned on.

If you swing a golf club or bat in this state, 2
A line along which one light emitting element moves is visually recognized by the practitioner as a locus of twelve light points. Since the two light emitting elements have brightness and colored light that stand out from the surroundings, the practitioner's eyes see a clear afterimage, which makes it easy to recognize the swing trajectory. Practitioners can also determine their own swing form, the shape of the incoming attack, and the turn of the wrist based on changes in the distance between the trajectories of these two light points, the position of the point where they intersect (hereinafter referred to as the intersection point), and the position where the light point disappears. You can immediately recognize the situation.

An embodiment of the present invention will be described below, followed by trajectories of two light points (hereinafter simply referred to as trajectories) when this practice device is used.
This will be explained in order of swing form and in batting.

<Embodiment> FIG. 1(a) is a perspective view of an embodiment of the present invention, and FIG. 1(b) is a perspective view of an embodiment of the present invention.
is a plan view showing the state attached to the driver. In the figure, the base (1) is, for example, @ 2 cm long, 6 cm thick, and 1 m thick.
It is composed of a sheet made of vinyl chloride resin of 5 cm, and on the top surface, a red light emitting LED (2R) and a yellow light emitting LED (2Y), which constitute two light emitting elements, are attached at an interval of about 5 cIrL, and the lighting display member (3 ). This lighting display member (3) is attached to the upper surface of the head α→ of the driver Qη using double-sided tape constituting the mounting member (4). In this case, the sweet spot υ of the club head
, and the line of sight E seen by the practitioner holding the club is on the line S' that cuts the upper surface of the head α. The lighting display member (3) is positioned so that the two LEDs (2R) and (2Y,) are located respectively, but in practice, it is best to position the two LEDs on a straight line parallel to the perpendicular S. , there is no problem even if it is slightly offset from the visual field @E.

L E D (2R), (2Y) of lighting display member (3)
is connected to a connector (6a) via an electric wire (5a). The connector (6a) connected to this connector (6a)
A) is connected to an output terminal (not shown) of the battery case (7) via an electric wire (5b). When installing the battery case (7) near the grip αQ of the screwdriver 〇η,
Recesses (8a,)y (8b) are formed in a shape that follows this, and the mounting member (9) is fastened and fixed as shown in FIG. Ru. The electric wire (5aL (5b)) is wound around the shaft αG of the driver (2) so as not to interfere with the swing motion, and if necessary, fixed with an adhesive tape (not shown) or the like.

The reason why the training device according to the present invention is made removable is to meet the demand for practicing using one's own club or bat. Furthermore, the battery case that houses the large-capacity battery is mounted near the grip in order to reduce the movement of the center of gravity of the club, and from this point of view it is desirable that each component be small and lightweight. In addition, when lighting two LEDs with two AA alkaline batteries, it was possible to use the device continuously for more than 24 hours.

Note that the lighting display member (3) of this example is placed on a straight line parallel to the baseball bat, with two L E D (2R), (2Y,)
Attach it so that it is positioned.

Furthermore, in the above embodiment, two LEDs emitting light of different colors were used. This is because it is easier to distinguish the loci of the two light spots if the LEDs are of different colors, but as long as the LEDs are bright enough, there is no problem even if the LEDs emit light of the same color.

Furthermore, in addition to LEDs, visible light semiconductor lasers, high-intensity electroluminescent elements, and even miniature light bulbs with high impact resistance can be used as the two light-emitting elements.

Further, in the above embodiment, the two LEDs are turned on and off by attaching and detaching the connector, but a switch may be provided.

FIG. 2 is a perspective view of another embodiment of the present invention, in which the battery is housed in the base. In the figure, the base (1
) is composed of a foamed synthetic resin molded product, and L E D (2
Recesses (1a) and (lbl) that fix R)-(2Y) in a position sunk below the top surface of the head, and pin-shaped lithium battery Q.
A concave portion (IC) constituting a battery case for accommodating O is formed, and the concave portion (IC) is attached by screw α force.

covered with a lid (1d). The switch (to) is the base (1
), and although not shown, two LE
D (2R), (2Y), the battery (10) and the switch (to) are connected by electric wires.The bottom surface of the base (1) is formed with a concave surface (1e) shaped to follow the top surface of the driver. , through the two through holes (1f) with wood screws,
It is screwed onto the head of the lever. The installation reference lines (IS) formed on both sides of the base (1) are connected to the two L E D
It shows a vertical plane including a straight line passing through (2R) and (2Y,), and serves as a positioning index when attaching the base (1) to the head of a driver bar.

By integrating the lighting display member (3) and the battery in this way, it is easy to attach and detach, and the weight of the bottle-shaped lithium battery is 1.
Since it is lightweight and weighs less than GP, the overall weight will not be so heavy that it will interfere with your practice.

Note that the two L E D (2R) and (2Y) are connected to the recess (l
The reason why they are housed in a) and (Ib) is to prevent damage from being hit by the ball.

FIG. 3 shows another embodiment of the present invention, and although this example shows an example attached to an iron, it can be similarly applied to a putter or a gateball stick.

Figure 3 (a) is a top plan view of the head portion of the iron held by the practitioner, Figure 3 (b) is an enlarged sectional view taken along the line B-B, and Figure 3 (c) is an enlarged cross-sectional view taken along the line C-C. In the side view, the lighting display member (3) accommodates a battery αG, and a mounting member (1g
) and screw (4), two L E D (2R), (
2y,) is placed on a straight line parallel to the perpendicular line S. Although detailed illustration is omitted, the battery acI is configured to be detachable.

Even if the position is offset from the line of sight E (as shown in FIG. 1(b)), there will be no practical problem if it is installed as described above.

The relationship between the driving form and impact shape and the loci of the two light emitting elements will be explained.

<In the case of driver shot practice> Figures 4 to 6 are diagrams for explaining the relationship between the trajectory of the two light emitting elements, the swing form, and the shape of impact, and all of them show the situation from the practitioner's perspective. Figure 4 shows the trajectory of the two LEDs in the case of Nukuware Impact (the trajectory R of the face side L E D (2R,) is shown as a solid line, and the other L
E D (2Y) trajectory Y is shown by a dashed-dotted line), and if the swing trajectory is "inside out" shown by A-A' in the figure, the position of the intersection OA will be to the right of the hitting point O, If the ball is hit as a "hook ball" and the swing trajectory is "square" as shown by B-B'j,
The position of the intersection point OB coincides with the batting point 0, and the first batted ball is a "nutrate ball μ", and the swing trajectory is [C-C'
In the case of ``outside-in'' shown by J, 1゛The position of the intersection point OC is from the left of the batting point 0, and the ball is a ``slice ball.''

FIG. 5 shows the case of a shut impact, and in any case where the swing trajectory is A-A', B-B/, O-c', the intersection point oA of the two trajectories R, Y is 013, 013,
o(, exists on the right side (from behind) of the hitting point 0, and the practitioner can identify how much of a shut impact it was from the distance from the hitting point O. In the case of a shut impact, the swing trajectory is A - A ' for 'strong hook ball 1/J, 13-B' for 'weak hook ball j,
When it is C-C', it becomes "Hikkake".

Figure 6 shows the case of an open impact.Whether the swing trajectory is A-A', B-B/, or C-C', the intersection points oA, OB, and Oc of the two trajectories are the practitioner's hitting points. It exists on the left side (from the front) of point O, and the practitioner can identify how open the impact was from the distance from point O. In the case of an open impact, if the swing trajectory is A-A', it will be a "butt out", if it is B-B', it will be a "weak slice pole", and if the swing trajectory is A-A', it will be a "weak slice pole".
When it is C', it becomes a "strong slice pole".

In this way, the practitioner has two L E D (2R), (
2Y) emits light, making it easier to recognize the swing trajectory, and also to determine the shape of the impact and the deviation from the Nukuwear impact from the positional relationship of the 12 trajectories R and Y and the positional relationship of their intersection point with respect to the hitting point 0. explain. FIG. 7(a) shows two trajectories R2Y in the state of square swing and square impact, the face of the putter is perpendicular to the target, and the two trajectories R and Y are straight lines toward the target, Moreover, the two trajectories R and Y overlap over the entire length.

FIG. 7(b) shows a case in which the swing locus is an arc in Nukuware Impact, and the direction of the ball is not determined. Further, FIG. 7(C) shows the case of an open impact, where the two trajectories R and Y are visually recognized as two trajectories with the trajectory Y on the near side, and the ball is hit as a slice bow. Further, FIG. 7(d) shows the case of a shut impact, where one trajectory is visually recognized as two trajectories on the near side, and one batted ball becomes a hook ball.

This example shows the case where the swing trainer shown in Figure 1 is mounted on the line of sight E (shown in Figure 1 (b)) that looks at the perpendicular line passing through the sweet spot using an L-shaped mounting bracket (not shown). However, when using the swing trainer shown in Figure 8, the positions of the trajectories R and Y simply move in parallel, resulting in two trajectories R.
, Y are not different in any way.

A gateball stick can also be used in the same way since it has the same swing trajectory as a puttball stick.

Next, the case where it is used for practicing swinging a baseball bat will be explained. Figure 8 shows the correct case of the stone lamp A, that is, the stone is attached to the right side of the body and the right hand reaches the position of hitting point 0 in front of the practitioner shown in the diagram (from (A) to the middle of the diagram). It shows the state of two trajectories R and Y in the case of an ideal Hatsu♂ Nogu form where the neck is not turning and the right wrist starts rotating from position -2-A as shown in the figure (C). The position of the intersection point OA of R and Y coincides with the position of the dot O,
The locus R disappears at a point (e) after passing the position (in the figure).

Figure 9 shows the state of the two trajectories R and Y in the case of a swing form in which the right wrist has already turned at the time of impact. The trajectory R disappears in the foreground, and the trajectory Y also disappears after passing the position (shown in the figure).

Note that whether or not the stone is far from the right side of the body can be recognized by looking at the distance from the practitioner to the two trajectory holes, Y.

<Effects of the Invention> The present invention includes a lighting display member in which two light emitting elements are fixed at a predetermined interval on the upper surface of a base, and this lighting display member is attached to the upper surface of the ball-striking part of a batting club used for swing practice. The mounting member and the above-mentioned 2
This swing practice device is equipped with a battery that supplies power to two light-emitting elements.If you attach this swing practice device to a batting stick and practice your swing, you will not only be able to easily recognize the trajectory of your swing, but also be able to easily recognize the shape of the impact. This has the effect of allowing you to easily and immediately grasp the degree of wrist curvature during the swing.
