Supporter for exercising golf swing

Supporter for exercising golf swing description/claims

The present invention relates to supporters for exercising golf swing, and more specifically to supporters for exercising golf swing enabling a user to swing a golf club with an ideal form repetitively.

There have been known various types of supporters for golf swing and tools for correcting swinging forms. For instance, JP S54-6178 A (Patent document 1) proposes a correcting tool which forcefully approximates a body and an arm (for instance, a right arm) to each other with a belt or the like so that the user can swing a club preserving the posture. With the correcting tool for swinging form, it is possible to forcefully keep one side in a closed state, but the other arm is completely free from the correcting tool, and therefore it is difficult to maintain the so-called triangle formed with the user's shoulders and both arms.

JP H04-70066 U (Patent document 2) proposes a tool for correcting movement of both arms. In the invention, both arms of a user are always kept at positions close to the user's body, and therefore the user can exercise golf swing in the state where the user's both arms are kept in the forcefully closed state. When the both arms are kept at forcefully closed state as described above, the user's right arm (when a right arm is a dominant arm of the user) is advantageously kept in the forcefully closed state and also a space between the both arms are kept constant. However, at the same time, also the left arm is kept in the forcefully closed state, and therefore the left arm can not naturally move, which causes an awkward and unnatural swing.

JP H08-336628 A (Patent document 3) discloses a golf exercise tool for golf swing enabling exercise of golf swing always keeping a user's right side in the tightened state, and the tool comprises a pad section having a predefined thickness to which an arm is mounted and side pad sections extending from both sides of the pad section each having a attachment band which is disconnectably attached to an upper portion of an arm or a shoulder of a user. When this golf exercise tool is set on a right arm to exercise golf swing, it seems that the user can learn a swing form keeping the right side in the forced state by mounting the user's right arm on the pad, but both front arms of the user are not restricted at all, and therefore the tool is not suited to exercise of maintaining a triangle formed with the user' shoulders and both arms.

Patent document 3 discloses a tool for exercising golf swing based on a combination of supporters for right and left wrists each comprising a ring of an elastic band restricting a wrist. The supporters for both wrists are effective in preventing an open posture of each wrist, but can not suppress a return of wrists when impacting a golf ball, and therefore the supporters are not useful in exercise of square impact in golf swing.

JP 3051619 U (Patent document 4) discloses an arm ring which is set on each arm and is connected to another one set on another arm like handcuffs. In this arm ring, a belt-formed telescopic section capable of expanding and contracting is provided thereon, and an adhesive section which can easily be adhered to or peeled off is provided at a substantially central portion of the telescopic section. When gripping a club, the inner adhesive sections of arm rings set of both arms can be adhered and connected to each other, and movements such as slight expansion or slight contraction such as waggling or impacting are mitigated by the telescopic section, and when a balance is lost during motion or an unnatural motion is performed, the telescopic section extends to the limit and the adhesive sections of the two arm rings are separated from each other for preventing injuries. With the arm rings as described above, however, like in the tool for exercise of golf swing as described above, it is impossible to suppress turning of wrists in the impact zone.

All of the supporters for exercise of golf swing are used for correcting a user's swinging motion to preferable golf swing by fixing both arms or both wrists with a belt or the like to prevent both elbows from moving away from each other, and when the user swings a club after the supporters for exercise of golf swing are removed, the user's swinging posture easily returns to that before correction, which means that the supporters are not effective in correcting a swinging posture in golf.

In association with progress in golf clubs, also golf swing regarded as ideal has been changing. A driver which was used in the past comprises a persimmon head and a heavy steel shaft, and in those days it was regarded important that a player grips a club in the mode of square gripping and turns arms to raise the head speed. In contrast, recently a main type of golf clubs, especially a driver has a large volume head made from titanium and a light weight shaft made from carbon, and the club has a high inertial moment. When using a recent club, if the hands are turned excessively like in the old fashion of golf swing, the inertial moment is high, so that a hit ball sometimes flies in a wrong direction. To overcome this problem, recently a club is held rather strongly for swinging, and rotation of hands is held as much as possible in the impact zone, and rotation of a body is controlled in swinging so that the club face can accommodate square impact.

An object of the present invention is to provide a supporter for exercise of golf swing minimizing a gap between a state in which the supporter is mounted and a state in which the supporter is not mounted and highly effective for exercising golf swing.

Another object of the present invention is to provide a supporter for exercise of golf swing which facilitates repetitive exercise of on-plane swing (means golf swing keeping a club head on a correct swing plane) which is currently regarded as the most ideal golf swing.

The supporter for exercise of golf swing according to an embodiment of the present invention comprises a block-like space retaining body which is closely attached on both wrists or both front arms within a triangle formed by both shoulders and a grip during golf swing and also having hardness and elasticity or a buffering function enough to prevent deformation against a pressing force by the both wrists and the both front arms during addressing and swinging; and a band provided on the retaining body and enabling amounting of the retaining body on either one of the both wrists or the both front arms.

The supporter for exercise of golf swing according to another embodiment of the present invention comprises a block-like space retaining body which is closely attached on both wrists or both front arms within a triangle formed by both shoulders and a grip during golf swing and also having hardness and elasticity or a buffering function enough to prevent deformation against a pressing force by the both wrists and the front arms during addressing and swinging; and a rope provided on the retaining body for hanging down the retaining body from a user's neck.

Preferably the space retaining body has a recessed portion formed along curved surfaces of the both wrists or the both front arms in a contact section where the space retaining body contacts the both wrists or the both front arms.

The space retaining body is preferably made from any one of foamed styrol, foamed urethane, synthetic resin, synthetic rubber, or a combination thereof.

With the supporter for exercise of golf swing according to the present invention, when a user exercises swing using this supporter, the user is required to intentionally try not to widen a space between the user's both arm, and a difference in feelings between exercising and actually playing on a golf course is small, so that the user can learn an ideal swinging form without fail.

Furthermore the supporter for exercise of golf swing according to the present invention provides the effect of suppressing rotation of hands in the impact zone. In other words, if a player rotates his or her hands turning the palms upward, a space between the both wrists or between the both front arms becomes narrower, but with the supporter for exercise of golf swing according to the present invention, because of the space retaining body, a space during addressing is maintained during swinging, and a motion causing rotation of hands is inevitably suppressed.
