Claims (1)

[Claims for Utility Model Registration] Consisting of an upper support 2 and a lower support 3, the upper support 2 holds the saddle 1 rotatably while maintaining the rotational axis O' of the saddle 1, and the lower support 3 supports the rotation of the saddle 1. It is provided at a position set back from the axis O' at a predetermined distance, the lower part of the lower support 3 stands on the leg 4, and the upper part of the lower support 2 allows the upper support 2 to rotate at a predetermined angle. The axis of rotation O' of the saddle 1 held by the upper support 2 and the lower support 3
is a golf swing form practice table in which the pivot axis O of the saddle 1 is parallel to each other, and when the golf swing practitioner 5 practices his swing with the saddle 1 in contact with his groin area, he shifts his weight after address. In this case, the upper strut 2 rotates by a predetermined angle with respect to the lower strut 3, and then by twisting the waist, the saddle 1 can move by a predetermined angle with respect to the lower strut 2, and in this state, the shoulder further, during downswing, the saddle 1 returns to its original position relative to the upper support 2, and the upper support 2 also returns to its normal position N relative to the lower support 3, and furthermore, at the time of impact, only the upper support 2 is in a predetermined position relative to the lower support 3. In a golf swing form practice table which is rotated at an angle and is designed to finish in that state; when the golf swing practitioner 5 is in a state where the upper support 2 is connected to the lower support 3 and the groin part is attached to the saddle 1, The upper support column 2 is configured to be able to slide forward,
Normally, the upper strut 2 is configured to be returned to the retreated position by a spring 10d relative to the lower strut 3, and the upper strut 2 moves with respect to the lower strut 3 in the form from the time of impact to the time of the finish. A golf swing form practice table characterized by being configured to be able to slide forward as the golf swing form moves. The upper support column 2 and the saddle 1 are normally kept in the retracted position Y with respect to the lower support column 3, and the slide mechanism 10 is capable of sliding the upper support column 2 and the saddle 1 forward as the hips move. It consists of two parallel guide rails 10a, upper and lower, provided on the upper and lower supports 2, and guide rollers 10b provided on the lower supports 3, and a spring 10d is stretched between the upper supports 2 and the lower supports 3. The golf swing form practice stand according to claim 1, characterized in that: Place the saddle 1 in the normal position N with respect to the upper support 2.
The mechanism that enables rotation by a predetermined angle from the top of the upper support column 2 includes two stopper holes 11 formed at a predetermined angle in the upper part of the upper support column 2 and a pin 13 pushed by a spring 12 provided in the saddle 1. A golf swing form practice stand according to claim 1, characterized in that the tip of the pin (13) is fitted into the stopper hole (11). The lower support column 3 is held by a lower support column outer cylinder 3b, and the lower support column 3 is constantly biased by a spring 14 of the lower support column outer cylinder 3b. Golf swing form practice table.
