Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf straightening device, and more particularly to a device suitable for straightening a golf swing form.

[0002]

2. Description of the Related Art In golf, in order to fly a golf ball (hereinafter simply referred to as a ball) further with less force, at the moment of impact of the club head hitting the ball, the face of the head hits the ball. It is said that it is important to swing so that it becomes a square and hit the club down against the ball.

In order to make such a swing, a backswing (takeback) is performed in a preferable form together with how to grip the club and an address when the club is held.
It's important to hit the ball with a club that leads to a follow throw, especially the form when backswing. For example, in the backswing, as shown in FIG. 9, the left and right arms 3 holding the club 1,
5 to pull up 5 to form a top position at a preferred position, or to bend the left wrist so that the shaft 7 of the club 1 and the left arm 3 form an L-shape to form a so-called "cock". You need to wear it.

In FIG. 9, reference numeral 9 is a golf player, reference numeral 11 is the head of the club 1, and reference numeral 13 is a ball. However, it is not easy to wear a preferable swing form, and it is a common experience for a general golfer to fall into a self-styled swing form at any time.

Therefore, various devices for correcting swing forms have been conventionally provided. For example, an annular swing guide that surrounds a swinging batter is provided. This is so that an appropriate form can be acquired by taking back the club along the swing guide.

[0006]

However, the ring-shaped swing guide has a large diameter of about 1.5 to 2 m,
It is fairly robust from the perspective of guiding the club, and is generally fixed and expensive to use. Moreover, it was unsuitable for personal use at any place such as a golf course or a driving range.

Incidentally, the general foam straightening device other than the above-mentioned swing guide also tends to be large in size and expensive, and cannot be easily used at any place. The present invention has been made to solve such a conventional drawback, and an object of the present invention is to provide a golf straightening device that can be used at any place and has a relatively simple and inexpensive structure.

[0008]

In order to solve such a problem, the present invention is directed to a light emitting portion for emitting visible light from a shaft end face side opposite to a head to the outside, and a drive for driving the light emitting portion. The club and the power supply unit that supplies power to the drive unit. Further, in the present invention, a condensing optical system that condenses visible light into parallel light may be arranged on the front surface side of the light emitting section, or the light emitting section, the driving section and the power source section may be built in the grip of the shaft. It is possible.

Further, according to the present invention, it is preferable that a switch for turning on / off the emission of the visible light is provided in the grip, or a gravity sensitive element is used as the switch. Furthermore, the present invention may have a configuration in which a beam splitter is arranged on the front optical path of the condensing optical system.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The same parts as those in FIG. 9 described above are designated by the same reference numerals. 1 and 2 are a schematic sectional view showing an embodiment of a golf straightening device according to the present invention and a perspective view of a club having the golf straightening device built therein. In FIGS. 1 and 2, a club head 11 is formed on one end of a general shaft 7 (not shown in FIG. 1), and a grip 15 is put on the other end.

The grip 15 is formed by molding a synthetic or natural rubber material, a synthetic resin having elasticity, artificial or synthetic leather into an elongated cap shape and press-fitting it, or the club shaft 7
It is fixed by being wound around and formed. This grip 1
The shaft 5 is partially covered with the shaft 7 partway in the axial direction, and the golf straightening device, which is the main part of the present invention, is built in on the tip side that does not overlap the shaft 7.

That is, in the grip 15, a hollow portion 17 that does not overlap with the club shaft 7 extends from the shaft 7 side toward the tip and opens, and in this hollow portion 17, a power supply battery 19, a drive circuit 21, and a light emitting element. 23 and the condensing optical system 25 are fixed while being supported by the grip 15, and at least the light emitting element 23 and the condensing optical system 25.
Are coaxially located on the club shaft 7. The power supply battery 19, the drive circuit 21, the light emitting element 23, and the condensing optical system 25 are preferably integrated in a tubular shape and arranged to be inserted into the hollow portion 17 of the grip 15.

The power supply battery 19 is a conventionally known AA to AA5 dry battery or a button type battery, and is a power supply unit for supplying a DC power supply to the drive circuit 21. The drive circuit 21 uses the power battery 19
Is a drive unit composed of an electronic circuit for driving the light emitting element 23 to emit light by the DC power source from, and has a switch (not shown in FIGS. 1 and 2) for turning on and off the emission of visible light.

The operation button 27 for turning the switch on and off penetrates the grip 15 and projects so that the switch operation is easy and does not hinder the swing. By operating the operation button 27, a DC power source from the power battery 19 to the drive circuit 21 is provided. Is turned on and off, and the light emission drive of the drive circuit 21 is turned on and off. Light emitting element 23 driven to emit light by drive circuit 21
Is a light emitting unit such as a laser light emitting diode, LED, LD, or electric bulb, and is arranged so as to emit the visible light emitted toward the tip of the grip 15.

The condensing optical system 25 is a convex lens made of, for example, glass or plastic arranged in the optical path in front of the light emitting element 23, and refracts the emitted visible light into parallel light.
As shown in FIG. 2, the club shaft is fired along the axis of the shaft 7 from the club shaft end surface side opposite to the head 11 to the outside.

FIG. 3 is a schematic block diagram of the above-mentioned golf straightening device, showing a power supply battery 19, a drive circuit 21, a light emitting element 23 and a condensing optical system 25, and a switch 2
When 9 is turned on, the drive circuit 21 drives the light emitting element 23 by the power source from the power source battery 19, and the visible light from the light emitting element 23 is collimated and emitted by the condensing optical system 25. The switch 29 operates by, for example, pressing the operation button 27 described above.

By using the club 1 having the golf straightening device of the present invention thus constructed in the grip 15 and gripping the grip 15 to address and press the operation button 27, the side opposite to the head 11 is detected. Visible light emitted from the end surface of the grip 15 hits the body of the golfer 9, so if the position where the visible light hits is confirmed, the club 1
It is easy to determine whether or not is set at a preferable position. Also,
When the club 1 is backswing while the operation button 27 is being operated and the "cock" is formed at the position (cock position) where the left arm 3 is parallel to the ground, as shown in FIG.
Since the end surface of the club 1 on the grip side faces toward the ground, it is possible to know whether or not a preferable "cock" is formed by checking the position where visible light hits.

Further, if the left and right arms 3 and 5 are pulled up to form the top position while keeping this state fixed, it becomes easy to wear a preferable backswing form, and looking back, the club 1 There is an advantage that it is less necessary to visually check the position of the left arm 3 and it can be used day or night. It can be used even in dark surroundings. Moreover, the golf straightening device is built in the grip 15,
Since the appearance is not so different from that of the normal club 1, it can be used at any place, and it is also possible to emit light and stop at will.

Further, in the golf straightening apparatus of the present invention, the position of the club 1 can be confirmed without disposing the condensing optical system 25, but the condensing optical system 25 is provided to emit parallel light. With this, the position where the visible light strikes becomes brighter and is easier to see. Further, in the structure in which the golf straightening device of the present invention is built in the grip 15, there is an advantage that the grip 15 can be detached and put in another club 1 to be used in the same manner. It is economical because it can be used for a plurality of clubs 1 with the grip 15.

However, the golf straightening device of the present invention is built in the shaft 7 in addition to being built in the grip 15.
It is also possible to use a structure in which the end face side is fired to the outside through the hollow portion 17 of the grip 15.
It is also possible to mount it on the outer periphery of the shaft 7 and shoot the outside of the shaft 7 or the grip 15 along this axis from the end surface side of the shaft 7 (grip 15) opposite to the head 11. The point is that it should be provided in club 1. In such a golf straightening device of the present invention, if the switch 29 is formed so as to continuously turn on the drive circuit 21 for a certain period of time, for example, for 3 to 5 seconds, by pressing the operation button 27 once, Since it is possible to deal with one swing even by pressing the shot operation button 27, it is not necessary to pay attention to the switch operation of the operation button 27 during the swing.

Further, in the structure using the light emitting element which emits the laser visible light as the light emitting element 23, the emitted visible light can be radiated linearly and strongly than the LED, the LD or the electric bulb, so that the position where the visible light hits is High brightness makes it easier to understand. The luminous flux of visible light emitted is
Although depending on the types of the light emitting element 23 and the condensing optical system 25, it is 3 to 15 mm, more preferably 5 to 10 mm from the viewpoint of easy viewing.
Will.

Further, according to the present invention, since the grip 15 is provided with the operation button 27 for turning on / off the visible light, the grip 15
You can turn on and off the light-emission operation just by grasping as usual, and it is easy to operate because the light-emission and rest are easy.
The battery 19 of the power source has a long life. However, the present invention is not limited to the configuration in which the operation button 27 is provided on the grip 15. Moreover, it is also possible to adopt a configuration using a gravity sensitive element 29 as shown in FIG. 5 as the switch. This gravity-sensitive element 29 has a pair of movable terminals 29 inside a shell 29a.
When the magnet 29d is brought close to the movable terminals 29b and 29c outside the shell 29a, the movable terminals 29b and 29c are moved by the magnetic fields. It has a structure in which contact is conducted.

The magnet 29d uses the end P as a fulcrum to form the shell 2
The gravity-sensitive element 2 is rotatably supported at the end of 9a.
The displacement of 9 causes the magnet 29d to be inverted and displaced by a maximum of 180 °. Reference numeral 29e is a stopper that restricts the displacement of the magnet 29d. In such a gravity-sensitive element 29, as shown by the broken line in FIG.
If the position does not overlap 9a, the movable terminals 29b, 29
c open and switch off, 180 °
When the magnet 29d is reversely displaced and overlaps the shell 29a and comes close to the movable terminals 29b and 29c, the switch is turned on.

Therefore, when the grip 15 is gripped and addressed, the end surface of the grip 15 faces upward.
Gravity sensitive element 2 so that it is switched off like A
If 9 is properly arranged in the grip 15, the backswing is performed and the club 1 is switched off to a position parallel to the ground as shown in FIG. Then, as shown in FIG. 6C, when the end surface of the grip 15 faces the ground in the cock position, the gravity-sensitive element 29 is switched on and visible light is automatically emitted downward. Even at the top position where the club 1 is parallel to the ground as in D, the gravity-sensitive element 29 remains switched on and visible light continues to be emitted.

During the follow-throw-swing of the club 1, the gravity-sensitive element 29 is switched off in the order shown in FIGS. 6D to 6A to automatically stop the emission of visible light. Therefore, switch 2 according to the swing of club 1.
Since 9 turns on and off and emits light, a switch operation is not necessary and the operation becomes easier. The above-described golf straightening device of the present invention is provided on the end face side of the grip 15
Although the visible light is emitted in the directions, the present invention is not limited to this, and the visible light may be emitted in a plurality of directions.

For example, as shown in FIGS. 7 and 8, a tubular knob 31 is coaxially and rotatably attached to the end face side of the grip 15, and a beam splitter is provided on the front optical path of the condensing optical system 25. 33 is arranged and the hollow portion 3 of the knob 31 is arranged.
1a, and visible light from the end face side of the knob 31 is emitted from the through-hole 31b provided on the side surface of the knob 31 and refracted by, for example, 90 ° with respect to the optical path on the front side of the condensing optical system 25. It is configured as possible. The other configuration is similar to that of FIG. 1, and thus the description is omitted. The beam splitter 33 is formed by laminating two prisms made of, for example, glass or a plastic material.
The incident light from No. 5 is dispersed and the light amount of 1/2 is emitted in the optical path of the incident light and in the direction perpendicular to the optical path.

In the golf straightening apparatus having such a structure, when the club 1 is backswing and becomes parallel to the ground at the top position, the axis of the club 1 is extended from the through hole 31b of the knob 31 as shown by a broken line B in FIG. Visible light refracted by 90 ° is emitted and hits the ground. In addition, in FIG. 9, the knob 31
The illustration of the through hole 31b is omitted. Therefore, if you confirm the position where the refracted visible light hits the ground, the club 1
It is possible to easily determine whether or not is parallel to the ground at the top position without looking back and visually observing the position of the club 1. Further, since the knob 31 is rotatably attached to the end portion of the grip 15, there is an advantage that the emission direction of visible light that is radially refracted from the club 1 can be arbitrarily changed.

The direction of emission of visible light refracted from the axis of the club 1 is arbitrary, and the beam splitter 33 may be selected accordingly and the through hole 31b may be provided. By the way, it goes without saying that the golf straightening device can be configured by appropriately combining the above-described embodiments.

[0029]

As described above, in the golf straightening apparatus of the present invention, the light emitting portion that emits visible light from the shaft end surface side opposite to the head toward the outside, the driving portion for driving the same to emit light, and the driving thereof. Since the club is equipped with a power supply unit that supplies power to the club, it is easy to determine whether the club is in the preferred position by checking the position where visible light hits when addressing, and when the club is backswing. Since the end surface side of the grip faces the ground direction, it is easy to determine whether or not a preferable backswing form is obtained by checking the position where visible light hits. Therefore, you can easily wear a preferable swing form with a simple operation, you do not need to look back and check the position of the club or arm, and since it can be built in or attached to the club, you can Can be used in place. Further, in the configuration in which the condensing optical system is arranged on the front surface side of the light emitting portion, it is easy to discriminate because the position where the visible light hits becomes brighter, and the light emitting portion, the driving portion and the power source portion are built in the grip. With the configuration, one grip can support a plurality of clubs, which is economical. In the configuration in which a switch for turning on / off the emission of visible light is provided in the grip, the switch can be operated by a normal address operation such as gripping the grip, and the operability is good. Further, in the configuration using the gravity-sensitive element as the switch, the emission of visible light is turned on / off simply by backswinging the club without being aware of the switch operation, and the swing can be performed naturally. Then, in the configuration in which the beam splitter is arranged on the front optical path of the condensing optical system, a part of the visible light from the condensing optical system is dispersed at an appropriate angle, and when the club is backswing, the separated visible light is dispersed. It is possible to radiate it toward the ground and check the position of the club during backswing.
