Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a state where a grip end fixing unit U composed of a grip end adapter positioning tool X and a grip end adapter A according to the present embodiment is fixed to a grip end of a grip G of a golf club, and FIG. FIG. 2 shows an exploded perspective view of FIG. 1.
The grip end adapter A includes an acceleration sensor, a posture sensor, and a communication device as functions, and can detect the angle and movement of the golf club. Since the reference coordinates of the attitude sensor and the acceleration sensor are set on the premise that they are attached to the grip end at a specific position, the grip end adapter A needs to adjust the rotational position around the shaft center axis of the club to a predetermined one. There is.

3A shows a plan view of the grip end adapter A, FIG. 3B shows a front view of the grip end adapter A, and FIG. 3C shows a bottom view of the grip end adapter A. In the grip end adapter A, the above-mentioned functional parts are housed in a flat cylindrical main body whose upper and lower surfaces are sealed, and the engaged recess A1 is cut out on the outer peripheral edge of the upper surface at four locations on a substantially rectangular column. Is formed. In addition, an instruction mark A11 serving as a reference for engaging the grip end adapter positioning tool X is drawn at one place near the outer peripheral edge of the upper surface. Here, this instruction mark
If the grip end adapter A is positioned on a plane including the center mark M of the grip G and the shaft central axis, the grip end adapter A is positioned at an assumed rotational position around the shaft central axis of the club. Further, an engagement protrusion A2 provided with a bulge for engaging with a through hole provided at the center of the grip end end portion of the golf club and locking to the front end side that can be fixed is provided on the bottom surface. Thereby, the grip end adapter A is fixed to the grip end of the grip G so as to be able to rotate only around the shaft center axis. The engagement protrusion A2 is formed so as to fit relatively tightly into the grip end hole and not rotate around the shaft central axis unless a certain amount of force is applied. Here, the function of the grip end adapter A is exemplified by detecting the physical posture and movement of the club by the acceleration sensor and the posture sensor, but is fixed at a specific position with respect to the rotation around the shaft central axis. Any device having a required function can be applied.

  The grip end adapter positioning tool X is for positioning the rotational position of the grip end adapter A around the central axis of the shaft. 4 (a) is a plan view of the grip end adapter positioning tool X, FIG. 4 (b) is a front view of the grip end adapter positioning tool X, and FIG. 4 (c) is a bottom view of the grip end adapter positioning tool X. FIG. 4D is a side view of the grip end adapter positioning tool X, respectively. The grip end adapter X is provided on the main body 10 made of a flat cylindrical body, the sight 20 fixed to the side surface of the main body 10, and the bottom surface of the main body 10. It is comprised from the engaging convex part 30 engaged with each to-be-engaged recessed part A1 of the said grip end adapter A. As shown in FIG. The sighting device 20 is a thick plate body having an isosceles trapezoidal shape in plan view, and a groove 21 having an inverted triangular section is formed at the center of the upper surface. The edge line formed at the bottom of the groove 21 is gently inclined so as to approach the main body side toward the bottom surface.

Next, a method for positioning the grip end adapter A using the grip end adapter positioning tool X having the above-described configuration will be described. First, the user inserts and fixes the engagement protrusion A2 of the grip end adapter A into the hole of the grip end. Next, the engagement convex part 30 of the grip end adapter positioning tool X is engaged with the engaged concave part A1 of the grip end adapter A. At this time, the sight 20 is made to face in the direction indicated by the instruction mark A11 of the grip end adapter A. The above operation results in a state as shown in FIG. In this state, the grip end adapter A is not yet fixed at the assumed position. Therefore, first, the user removes the grip end adapter positioning tool X and the grip end adapter A fixed integrally therewith so that the sight 20 is directed in the direction of the center mark M drawn on the grip G. Rotate. In this state, when the center mark M of the grip G is seen from the grip end side through the sight 20, it becomes as shown in FIG. Normally, at this stage, as shown in this figure, when the line of sight is aligned with the edge line of the groove bottom of the sight 20, the line of sight does not coincide with the center mark M. Therefore, the grip end adapter positioning tool X is rotated together with the grip end adapter A so as to be aligned with the edge line of the groove bottom of the sight 20 and the center mark M as shown in FIG. As a result, the rotational position of the grip end adapter A is adjusted to the assumed position. Finally, the grip end adapter positioning tool X is removed as shown in FIG. 6 to complete the operation.
Thus, since the grip end adapter positioning tool X can be removed after positioning, it is not necessary to provide a positioning structure for the grip end adapter A, and the grip end adapter can be made smaller and lighter. . In addition, if the grip end adapter has an engagement recess corresponding to positioning, even a grip end adapter having a different function or form can be positioned by one grip end adapter positioning tool X.

(Modification)
In the above embodiment, the sighting device is used as a reference unit for adjusting the position reference, but other mechanisms may be used. FIG. 7 is a perspective view showing a state where the grip end adapter positioning tool Y and the grip end adapter A, to which a laser pointer is mounted as a reference portion, are fixed to the grip end of the grip G of the golf club. 8 (a) is a plan view of the grip end adapter positioning tool Y, FIG. 8 (b) is a side view of the grip end adapter positioning tool Y, and FIG. 8 (c) is a bottom view of the grip end adapter positioning tool Y. Each figure is shown.
The structure of the grip end adapter positioning tool Y is obtained by replacing the sight 20 of the grip end adapter positioning tool X described above with a laser pointer 40. The laser pointer 40 has the same mechanism as a general laser pointer. A laser diode, a drive circuit, and a power source are built in a cylindrical housing 41, and the light of the laser diode is converged by a collimating lens 42 provided at the tip. It is something to be made. Also, a push switch 43 for turning on / off the laser is provided at the rear end of the housing. The housing 41 is rotatably held between support supports 44 erected in parallel from the main body side surface of the grip end adapter positioning tool X. Thereby, as shown in FIG. 7, in a state where the grip end adapter positioning tool Y is fixed to the grip end, the laser emitted from the laser pointer 40 moves in a plane passing through the central axis of the shaft. Note that this holding is such that it does not rotate unless a certain amount of force is applied, and can be fixed at an arbitrary rotating position by moving it by hand.

  The use method of the grip end adapter positioning tool Y is substantially the same as that of the grip end adapter positioning tool X. However, in the positioning with respect to the center mark M, the light spot output from the laser pointer 40 is not centered but the center is used. This is done by matching with the mark M. That is, by adjusting the rotation of the laser pointer 40 relative to the support lid 44 and the rotation of the grip end adapter positioning tool Y and the grip end adapter A relative to the grip G, the light spot indicated by the laser pointer 40 is positioned on the center mark M. The grip end adapter A is adjusted to the assumed rotational position.

In addition to this, as a method for adjusting the reference of the position, instead of the light spot indicated by the laser pointer 40, an indicator needle 50 extending in parallel to the shaft central axis as in the grip end adapter positioning tool Z shown in FIG. Various modifications are conceivable, such that the tip of the indicator needle 50 is positioned on the center mark M.
Furthermore, even when the sighting device is used, the shape of the sighting device can be variously modified, and a scope type device or the like can also be adopted.
In addition, the shape of the engaging portion and the engaged portion that engage the grip end adapter and the grip end adapter positioning tool with each other can be any shape as long as they are fixed with respect to the direction around the shaft center axis. Can be adopted.
