  The present invention according to claim 4 is characterized in that the loft angle setting means is provided so that the loft angle can be set in a plurality of stages for each rotation angle.

  According to the first aspect of the present invention, it is possible to provide a golf club that can be set to an arbitrary loft angle by a simple operation with a simple configuration for setting the loft angle.

  According to the invention of claim 2, the loft angle setting means includes a gear member that rotates together with the head club, and a ratchet that is engageable with the gear member and restricts the rotation of the gear member in the opposite direction. By providing the mechanism, the mechanism for setting the loft angle can be simplified, and the manufacturing cost can be reduced by reducing the number of parts.

  According to the invention of claim 3, the direction of rotation of the club head at the time of setting the loft angle is a direction in which the loft angle increases, so that the club head has a direction in which the loft angle decreases due to the force received from the golf ball at the time of hitting However, the loft angle setting means regulates the rotation of the club head in the direction in which the loft angle is to be reduced. Therefore, the club head is prevented from rotating from the force received from the golf ball, and the ball is hit. The loft angle at the time can be maintained.

  According to the invention of claim 4, by setting the rotation angle in the loft angle setting means to be within 10 degrees, and setting the loft angle in a plurality of stages or more, for example, from 2 iron to 9 iron in ascending order of the loft angle, The golf of the present invention has a function equivalent to multiple golf clubs composed of consecutive counts with different loft angles in a normal iron type golf club set with PW (pitching wedge) and SW (sand wedge). It becomes possible to prepare for one club.

  Hereinafter, an embodiment of a golf club 1 of the present invention will be described with reference to FIGS. The golf club 1 of the present invention is configured to have a club head 3 having a face surface 2 as a striking surface and a shaft 4 to which the club head 3 is connected. An arbitrary score line (not shown) is formed on the face surface 2 of the club head 3. A grip portion (not shown) is provided on the opposite side of the shaft 4 to the side connected to the club head 3.

  Here, a loft angle setting means 5 is provided at a connecting portion between the club head 3 and the shaft 4.

  As shown in FIG. 2, the loft angle setting means 5 is provided with, for example, a distance between the teeth 6 at a predetermined pitch angle α, and is connected to the club head 3 by the first rotating shaft 7 and can rotate with the club head 3. A ratchet mechanism 11 having a gear member 8 such as a gear or a rack provided on the outer periphery and a locking claw 10 provided around the gear member 8 so as to be swingable by a second rotating shaft 9 is provided. In this ratchet mechanism 11, the gear member 8 is engaged with the teeth 6 of the gear member 8 every time the gear member 8 rotates one pitch angle α in the direction in which the loft angle θ of the club head 3 increases (counterclockwise direction in FIG. 2). When the claw 10 is provided so as to be engageable and the gear member 8 rotates in the reverse direction (clockwise direction in FIG. 2) in which the loft angle θ of the gear member 8 decreases, the locking claw 10 The gear member 8 is provided so as to be able to regulate reverse rotation (clockwise rotation in FIG. 2) by engaging with the 8 teeth 6.

  Further, the loft angle setting means 5 is not restricted for rotation in the direction in which the loft angle θ of the club head 3 increases (counterclockwise direction in FIG. 2). It is configured to be able to continue to rotate in the direction of increasing (counterclockwise in FIG. 2) and to make more than one rotation.

  Further, the pitch angle α as the rotation angle of the loft angle setting means 5 is, for example, a normal iron in which the 2nd iron to 9th iron, PW (pitching wedge), SW (sand wedge) are arranged in order from the smallest loft angle θ. In the type of golf club set, the loft angle θ of these golf clubs 1 is in the range of 0 to 90 degrees in the order of the above club sets 18, 21, 24, 27, 31, 35, 39, 43, 48, 56 ( In any case, the unit is degrees), that is, the difference in loft angle θ between adjacent counts is within about 10 degrees. Therefore, the pitch angle α is set to 0 degrees corresponding to such a golf club set. <Α ≦ 10 degrees, preferably 0 <α ≦ 5 degrees may be set. Further, the loft angle θ of each count in the golf club set is not limited to the above.

  For example, when the loft angle θ is set to 24 degrees corresponding to the loft angle θ of the fourth iron so that the loft angle θ is substantially the same as the loft angle of each count of the normal golf club set described above. In order to rotate the club head 3 by one pitch angle α and set it to 27 degrees corresponding to the loft angle θ of the 5 iron, the next pitch angle α when the current loft angle θ is 24 degrees is set to 4 The pitch angle α is set continuously or not so that the club head 3 stops rotating when the club head 3 is substantially the same as the loft angle θ of each count and is set to be approximately the same as the loft angle θ of each count. A continuous arbitrary angle may be set.

  Next, the operation of the golf club 1 having the above configuration will be described. In the golf club 1 of the present embodiment, the user plays by setting the loft angle θ of the club head 3 by the loft angle setting means 5 according to the remaining distance to the green and the situation where the golf ball is placed. Is.

  In the setting of the loft angle θ via the loft angle setting means 5, the club head 3 is rotated stepwise for each pitch angle α, and the club head 3 is held in its rotational position when the desired loft angle θ is reached. Then, the loft angle θ is set.

  Here, the club head 3 is provided so as not to rotate in the direction in which the loft angle θ is decreased by the loft angle setting means 5 (clockwise direction in FIGS. 2 and 3). When changing the setting to a loft angle θ having a small angle, the club head 3 is rotated until the loft angle θ reaches a maximum of 90 degrees, and the loft angle θ is further increased (FIGS. 2 and 3). In the counterclockwise direction), the loft angle θ is returned to 0 degrees, and then the club head 3 is increased once again in the direction in which the loft angle θ increases (the counterclockwise direction in FIGS. 2 and 3). To set the loft angle θ.

  Further, the operation when the golf ball B is hit with the golf club 1 of the present embodiment will be described with reference to FIG. When a golf ball B is hit with the golf club 1 with the right direction in the figure as the hitting direction, a force F1 acts counterclockwise on the golf ball B that is hit by the friction between the face surface 2 and the golf ball B at the time of hitting. In contrast to the backspin, the club head 3 rotates in the direction in which the loft angle θ decreases (clockwise in FIGS. 2 and 3) due to the longitudinal gear effect caused by friction with the golf ball B. The force F2 to be applied acts, but the rotation of the club head 3 in the direction in which the loft angle θ decreases (the clockwise direction in FIGS. 2 and 3) is regulated by the loft angle setting means 5, The loft angle θ at the time of hitting is maintained.

  In this way, by setting the loft angle θ of the club head 3 via the loft angle setting means 5 provided with the ratchet mechanism 11, the club head 3 provided so as to be able to rotate stepwise for each pitch angle α is predetermined. Since the loft angle θ can be easily set by simply stopping the rotation when the loft angle θ reaches the value, the operability is improved and the ratchet mechanism 11 reduces the loft angle θ (in FIGS. 2 and 3). Since the reverse rotation in the clockwise direction is also restricted, it is not necessary to newly provide a fixing means for preventing the reverse rotation of the club head 3, and the golf club 1 is made compact and manufactured by reducing the number of parts. Cost can be reduced.

  The above embodiment corresponds to claim 1 and is a golf club 1 comprising a club head 3 having a face surface 2 formed as a ball striking surface and a shaft 4 connected to the club head 3. The head 3 is provided so as to be rotatable in the direction in which the loft angle θ is increased in one direction, and the rotation in the direction in which the loft angle θ is decreased as the direction opposite to the direction in which the loft angle θ is increased is regulated. A loft angle setting means 5 which holds the rotation position for each pitch angle α (0 ° <α ≦ 10 °, preferably 0 <α ≦ 5 °) as a predetermined rotation angle and makes it possible to set the loft angle θ of the club head 3. It has.

  In this case, the structure of setting the loft angle θ is simplified by using the ratchet mechanism 11 including the gear member 8 and the locking claws 10 as the structure of the loft angle setting means 5, and the club is set by the loft angle setting means 5. A golf club 1 that can be set to an arbitrary loft angle θ can be provided by a simple operation by simply rotating the head 3.

  Further, the loft angle setting means corresponds to claim 2, and the gear member 8 provided so as to be rotatable together with the club head 3, and the club head 3, wherein the loft angle setting means is provided at a pitch angle α as a rotation angle. As a restricting means that engages with the gear member 8 during rotation in the direction in which the loft angle θ decreases, which is opposite to the direction in which the loft angle θ increases, and restricts rotation in the direction in which the loft angle θ decreases. A ratchet mechanism 11 having a locking claw 10 is provided.

  In this case, the mechanism for setting the loft angle θ can be simplified, and the manufacturing cost can be reduced by reducing the number of parts.

  Further, it corresponds to claim 3, and one direction as the rotation direction of the club head 3 in the loft angle setting means 5 is set to a direction in which the loft angle θ increases (counterclockwise direction in FIGS. 2 and 3). As a result, the force F2 applied to the club head 3 in the direction of decreasing the loft angle θ due to the force F1 received from the golf ball B at the time of hitting the ball, the loft angle setting means 5 tries to decrease the loft angle θ of the club head 3. Since the rotation in the direction (clockwise in FIGS. 2 and 3) is restricted, the club head 3 can be prevented from rotating by the force F1 received from the golf ball B, and the loft angle θ at the time of hitting can be maintained. can do.

  Further, the loft angle setting means 5 corresponds to claim 4 and the loft angle setting means 5 increases the rotation angle θ by a plurality of stages for each pitch angle α (0 degrees <α ≦ 10 degrees, preferably 0 <α ≦ 5 degrees). It can be set to.

  In this case, the pitch angle α in the loft angle setting means 5 is 0 degree <α ≦ 10 degrees, preferably 0 <α ≦ 5 degrees, and the setting of the loft angle θ can be set in a plurality of stages, for example, three or more stages. Thus, for example, in a normal iron type golf club set in which the 2nd iron to the 9th iron, PW (pitching wedge), SW (sand wedge) are arranged in order of increasing loft angle θ, different loft angles θ are provided. It is possible to provide one golf club of the present invention with a function equivalent to three or more golf clubs composed of three consecutive counts.

  In addition, this invention is not limited to the said Example, Various deformation | transformation implementation is possible. For example, although an iron type golf club has been described as an example in the present embodiment, the golf club of the present invention can be applied to a wood type golf club such as a driver or a fairway wood, a putter or the like. Further, a loft angle fixing means made of, for example, a screw member for fixing the club head 3 side and the shaft 4 side after the loft angle θ is set by the loft angle setting means 5 may be provided. In this case, since the fixing of the loft angle θ is reliable, the reliability of the golf club 1 is improved. Further, by providing a display unit such as a scale for displaying the loft angle θ of the club head 3 on the loft angle setting means 5, the club head 3 side, or the shaft 4 side, the setting or confirmation of the loft angle θ is facilitated. .
