Description

  The present invention relates to a golf club swing robot suitable for observing and evaluating the degree of deflection of a golf club shaft by mounting a golf club and simulating a swing process.

A conventional golf club swing robot is formed by a 1-axis 2-joint or 2-axis 3-joint composed of a driving joint serving as an upper body (shoulder joint) and a non-driving joint serving as an upper arm and a wrist joint. Is configured to bend in the rotational direction of the drive joint (rotating shaft). Therefore, when the golf club is mounted and the swing process is simulated, the swing direction can only simulate a two-dimensional simple movement, so even if the bending state of the mounted golf club shaft is observed, Only the lateral bending degree could be observed and evaluated, and the vertical bending degree could not be evaluated.
Therefore, as a matter of course, the conventional golf club swing robot has not been able to correctly evaluate the club shaft deflection when the golfer actually swings.
Note that the above prior art known to the applicant of the present application is not related to the literature known invention, and therefore, prior art document information is not disclosed in the present specification.

  The present invention has been made in view of such a current situation, and it is possible to almost faithfully simulate the movement when a golfer actually swings by holding a golf club, and thus, similar to a conventional swing robot. Of course, it can be used to evaluate the performance of golf club heads and golf balls, as well as three-dimensionally simulating the deflection of a golf club shaft when a golfer actually swings, to correctly determine the performance of the golf club shaft. An object of the present invention is to provide a golf club swing robot that can be evaluated.

The golf club swing robot according to claim 1 of the present invention that achieves the above-described object is a first robot that has a pseudo upper arm that acts as a shoulder joint on a pseudo upper body that is formed in a substantially columnar shape and rotates in a circumferential direction. A pivot is connected to the pseudo upper arm so as to move up and down, and a pseudo forearm is connected to the pseudo upper arm so as to move up and down, and a golf club to be tested serves as a wrist joint on the pseudo forearm. By detachably attaching to the third pivot and rotating the pseudo upper body in the circumferential direction, the pseudo upper arm, the pseudo forearm and the golf club are swung down to simulate the process from the top position to the impact position in the golf swing. It is characterized by making it.
In addition, the golf club swing robot according to claim 2 of the present invention continuously swings up again after swinging down the pseudo upper arm, the pseudo forearm and the golf club while rotating the pseudo upper body in the circumferential direction. It is characterized by simulating a continuous process from the top position in the golf swing through the impact position to the finish position by operating.

According to the golf club swing robot of the present invention, the pseudo upper body that rotates in the circumferential direction (horizontal direction), the pseudo upper arm that operates in the vertical direction (vertical direction), the pseudo forearm, and the golf club are combined. It is possible to simulate the movement of the mounted golf club to be tested from the top position through the impact position to the finish position, which is almost the same as when the golfer actually swings while holding the golf club.
Therefore, golf can be used to test and evaluate the performance of golf club heads and golf balls, as well as conventional swing robots of this type, as well as golf that occurs when a golfer actually swings a golf club shaft. Since it is possible to reproduce the three-dimensional deflection in the horizontal and vertical directions of the club shaft, it is possible to accurately test and evaluate the performance of the golf club shaft deflection.

  In addition, it is possible to simulate a shot mistake that a golfer actually causes by appropriately combining the motions (speed, timing, etc.) of the pseudo upper body, the pseudo upper arm, the pseudo forearm, and the golf club. It is also used for the golfer to learn club swing by showing the golfer's motions (speed, timing, etc.) of the simulated upper body, simulated upper arm, simulated forearm, and golf club directly or with video or numerical values. It becomes possible.

  Further, if a load sensor is incorporated in each pivot (joint) portion connecting the pseudo upper body, the pseudo upper arm, the pseudo forearm, and the golf club, the load applied to each pivot (joint) portion during the swing of the golf club is measured. Therefore, by analyzing the measured value, it is possible to evaluate the characteristics of the golf club, and it is possible to predict the load applied to the joint portion of the golfer and use it for swing training.

Hereinafter, examples of the present invention will be described in detail with reference to schematic drawings. However, the present invention is not limited to the illustrated examples.
The golf club swing robot according to the present invention corresponds to the upper body, the upper arm, and the forearm of the human body. It is basically composed of 4c and the like.

The pseudo upper body 1 is formed in a substantially columnar shape using a rigid material, for example, a hollow steel pipe, and is vertically rotatable on a support frame (not shown) or the like in the circumferential direction (horizontal direction). Installed.
At this time, the pseudo upper body 1 may be set up in a strictly vertical state, or may be installed upright in a slightly tilted state.
The size (outer diameter and length) of the pseudo upper body 1 can be arbitrarily designed without any restriction.

  A pseudo upper arm 2 is connected to a pseudo upper body 1 that is rotatably installed in a circumferential direction (horizontal direction), and is movably connected to the pseudo upper arm 2 by a first pivot 4a that functions as a shoulder joint. 3 is connected to a second pivot 4b acting as an elbow joint so as to be movable up and down, and a golf club 5 to be tested is detachably attached to the pseudo forearm 3 via a third pivot 4c serving as a wrist joint. Attached to.

  The pseudo upper arm 2 and the pseudo forearm 3 are formed in a band plate shape having an appropriate length using a material having rigidity, for example, a steel plate, and the size (length) thereof is, for example, that of an adult male. It is preferable to form standard upper and forearm lengths.

  In addition, the pseudo upper arm 2 and the pseudo forearm 3 may be connected to the pseudo upper body 1 using only one piece, respectively. Two pseudo upper arms 2 are connected to the left and right sides of the pseudo upper body 1 standing upright by a first pivot 4a, and the pseudo forearm 3 is connected to both pseudo upper arms 2 by a second pivot 4b. The grip 5a of the golf club 5 is preferably attached detachably and vertically movable by the third pivot 4c so as to be sandwiched between the two pseudo forearms 3.

Next, the operation of the golf club swing robot according to the present invention will be described.
A pseudo upper arm 2 and a pseudo forearm 3 are already movably connected to a pseudo upper body 1 rotatably installed in a circumferential direction (horizontal direction), and a grip portion of a golf club 5 to be tested is connected to the pseudo forearm 3. 5a is attached to the third pivot 4c so as to be movable up and down.

Thereafter, the pseudo upper body 1, the pseudo upper arm 2, the pseudo forearm 3, and the golf club 5 to be tested are operated and moved, respectively, and set to the top position as shown in FIG.
Then, from the state, the pseudo upper body 1, the pseudo forearm 3 and the golf club 5 are simultaneously swung down while rotating the pseudo upper body 1 in the circumferential direction.
Then, the pseudo upper body 1, the pseudo upper arm 2, the pseudo forearm 3, and the golf club 5 to be tested cooperate with each other from the top position shown in FIG. 1 (a) to the intermediate shown in FIG. 1 (b). After going through the state, the golf ball B moves to the impact position shown in FIG. 1C, and the golf ball B is shot at the impact position.
As a result, a continuous golf swing movement from the top position to the impact position is simulated. Therefore, by adjusting the speed of rotating the pseudo upper body 1 in the circumferential direction and the speed of swinging down the pseudo upper arm 2, the pseudo forearm 3 and the golf club 5, the impact position is changed from the same top position as when the golfer actually swings. It is possible to simulate the continuous movement up to.

Further, the pseudo upper arm 2, the pseudo forearm 3, and the golf club 5 are swung down and rotated again continuously while rotating the pseudo upper body 1 in the circumferential direction, as shown in FIG. From the top position, the intermediate state shown in FIG. 1 (b) → the impact position shown in FIG. 1 (c) → the intermediate state shown in FIG. 1 (d), as shown in FIG. 1 (e). It works continuously until the finish position.
As a result, the entire process from the top position to the finish position through the impact position in the golf swing can be continuously simulated.

It is a schematic diagram showing an example of the implementation of the golf club swing robot according to the present invention and explaining the process from the top position to the finish position in the golf swing.
