Description

  The present invention relates to a park golf club having an adjustable angle (lie angle) between a shaft and a head used in park golf.

  In the park golf club, the angle (lie angle) between the shaft and the head is fixed. Although this angle is set for the average park golf player, it is not optimal for individual players and they must adapt their stance to a fixed club.

  Park golf is a sport that can be easily done with simple equipment, so players with various physical functions such as weak children, elderly people, and wheelchair users have come to participate.

  In the park golf club, since the angle between the shaft and the head (the lie angle) is fixed, an angle suitable for one's stance could not be confirmed. Also, there was no one club that could be used for right and left by using the angle adjustment function.

  Park golf clubs that can be adjusted and fixed to the optimal angle (lie angle) are effective for these people to play because the stance of setting up the club varies depending on the individual physical functions such as elderly people and wheelchair users. It is to realize a club that can be used within the range allowed by the rules of general golf tournaments.

  An object of the present invention is to provide an adjustable park golf club in which an angle (lie angle) between a shaft and a head can be arbitrarily set so as to adapt to body functions of various players.

Another object of the present invention is to provide an adjustable park golf club which can be used for right and left by a single club according to an adjustment angle of a shaft and a head.

  Another object of the present invention is to provide an adjustable park golf club in which the angle (lie angle) between the shaft and the head can be freely selected and the angle information of the club suitable for each player can be known. There is to do.

  Another object of the present invention is to provide an adjustable golf club in which the relative angle between the shaft and the head can be selected within a certain angle range, and the selected angle can be easily changed without using a special tool. There is.

  The above problems and other problems are basically overcome by the angle adjustment mechanism of the park golf club of the present invention. This is realized by a structure of a club golf club head having an outer shape that can be used in a normal state with a rotation pin incorporated therein and a shaft that can be fixed to the rotation pin. The head has vacancies extending from the bottom surface inside the club head to the top surface to ensure rotation of the shaft's binding. The bolted portion attached to the tip of the club shaft is inserted into the head cavity through a rotation pin incorporated therein through an opening in the upper surface of the head.

  The shaft and the head are tightly coupled by screwing the bolt portion attached to the tip of the shaft from the opening at the top of the head into the nut portion provided on the rotary pin incorporated therein. When the head is held in a state where the bolt of the shaft is properly screwed and the shaft is moved, the shaft rotates with the rotation pin in the head as an axis, and an angle (lie angle) between the shaft and the head can be arbitrarily obtained.

  The head hitting surface is selected to have a bilaterally symmetric shape that can be used in a normal range. If it is moved, the same rotation can be realized. If the shaft angle falls to the left with respect to the ball striking surface, it becomes a left-handed club, and if it has a right-side angle, it becomes a right-handed club. Can be realized.

  When the target angle is selected, the bolt attached to the shaft is further screwed. The receiving part attached to the terminal part of the bolt comes into contact with the upper surface of the head. When the screw is further screwed in, it is in a state of being pressed with a length having the rotation pin and the upper surface of the head as a span, and the head and the shaft are fixed.

  The tip of the rotating air chamber on the upper surface of the head is carved so as to have the same circumference around the rotation pin. On the other hand, a vertical load is applied. Further, by using an elastic material having a moderate frictional force for the receiving portion, the head and the shaft are difficult to rotate in a pressed state.

  Clamping is a method of fixing with a bolt attached to the shaft. Since the bolt is integrated with the shaft, the shaft having a large diameter is turned by hand, and the turning force is small. Angle adjustment is easily possible because no special tool is required for rotation.

  The current rotation angle suitable for the user can be confirmed by the vertical line passing through the center of the shaft close to the head surface and the horizontal line indicating the angle of the head upper surface.

  By changing the angle (lie angle) of the shaft and head of the park golf club, you can avoid using the player's stance for a club with a fixed angle as before, and set the angle that suits you. You can choose and play. In particular, Park Golf is an easy sport that small children, elderly people, wheelchair users, etc. can participate in, so there are variations in the physical ability and physical function of the people who play, and considering the difference in stance, It is impossible to fix to a certain range. For example, when trying to use a club with a ball placed on the front in a wheelchair, the angle between the shaft and the head must be reduced unlike the standing position. Make use of it. Also, because it is a wheelchair, it is difficult to hit the front on the course at all times, and there are many scenes where it is necessary to hit in an unnatural posture such as the position of the side. In this case, the angle between the shaft and the head is conversely The larger one is easier to hit, and the advantage of the present invention that the angle can be easily adjusted can be utilized.

  As technology improves, there are many cases in which custom-made equipment that suits one's own movement characteristics is custom-made. In the present invention, the angle between the head and the shaft changes, and since the memory indicating the angle is attached to the head, it is possible to confirm the optimum angle for itself, and it is possible to use it as a measuring instrument. Therefore, when placing an order with a manufacturer, it is possible to order a park golf club based on the angle, and by using the product of the present invention, it is possible to purchase equipment more suitable for the user.

  There are cases where clubs are rented out at the park golf course, but some users have a left-hand effect, so it is necessary to have both left and right clubs. In the present invention, since one can be used for right and left, management of tools is facilitated without any club shortage.

  Examples of the present invention will be described below.

  FIG. 1 is a perspective view showing a part of a head and a shaft for a park golf club according to the present invention. FIG. 2 is a side view of the same viewed from the left side. Referring to FIGS. 1 and 2, the shaft 30 is inserted from the top surface of the head 10 and connected. The head 10 includes a curved top surface 12, a curved bottom surface 14, a flat front ball striking surface 11, and a wall surface 13. The head 10 has a symmetrical shape when viewed from the surface 11. As will be described in detail below, the shaft 30 is integrated with the head 10 by screwing a bolt 33 attached to the shaft into the screw hole 41 of the internal rotation shaft 40 through the opening 16. Depending on the purpose of use, if necessary, a rubber wrap or soft foam padding (not shown) that seals the opening 16 to prevent dust or water or other objects from entering the gaps in the opening 16 ) May be used. Further, a small hole (not shown) for ventilating water may be provided on the head bottom surface.

  FIG. 3 is a cross-sectional view taken along line 1-1 in FIGS. 1 and 2, and allows the angle α (lie angle) of the shaft 30 to the head 10 to be adjusted, and these components are connected and fixed to each other in use. The structure inside the head 10 is shown.

  4 is a perspective view of the inside of the head when cut along a plane along line 1-1 in FIGS. The structure of the empty chamber which ensures a movement when the joining bolt 33 of the shaft 30 slides is shown. FIG. 5 is a perspective view of the rotating pin 40 housed inside the shaft 30 and the head 10 and shows a method of joining the joining bolt 33 and the screw hole 41 of the rotating pin.

  The upper fan-shaped air chamber 22 extends through the opening 16 into the head 10. The lower inverted fan-shaped air chamber 21 extends inside the head 10 through the gap of the rotary pin 40. A circular air chamber 23 for inserting the rotation pin 40 is provided at the boundary between the upper air chamber 22 and the lower air chamber 21.

  The air chamber 22 is configured to allow the upper portion of the bolt 33 attached to the shaft to be slid and moved when the angle is adjusted. Similarly, the air chamber 21 is capable of moving the lower portion of the bolt 33 that passes through the rotation pin 40. Is provided.

  The angle α (lie angle) between the head 10 and the shaft is such that when the head 10 is pressed with the shaft bolt 33 screwed into the screw hole 41 of the rotation pin appropriately and the shaft is moved, the shaft 10 rotates about the rotation pin 40 in the head. , Arbitrarily obtained within the movable range.

Since the structure of the head 10 has a bilaterally symmetric shape when viewed from the surface 11, the angle α (lie angle) between the head 10 and the shaft can be similarly adjusted to the left and right with respect to the vertical. When the angle α is smaller than 90 degrees, it can be adjusted for right-handed use, and when it is larger than 90 degrees, it can be adjusted for left-handed use.

  The final fixing of the head 10 and the shaft 12 is determined by determining the lie angle α of the target shaft in a state where the bolt 33 attached to the shaft is appropriately screwed into the screw hole 41 provided in the rotary pin 40 and then screwing in further. end with. A packing part 32 also serving as an anti-slip at the upper part of the bolt 33 comes into contact with the surface portion of the head 10 and is fixed by being clamped. The compression is maintained by the tension between the rotary pin and the head surface via the packing part 32. The head surface to which the packing 32 hits is a concentric circle with the rotation pin as an axis, so that the force is not distributed and it is applied perpendicular to the shaft, and the movement of the head angle α (lie angle) during use can be suppressed. I can do it. The packing part 32 is preferably made of an elastic material having a large sliding friction coefficient.

  The fixing of the head 10 and the shaft 30 can be realized by hand without using a special tool. Since the shaft 30 has bolts attached in advance, the shaft 10 has a large diameter, so that it can be easily fixed by rotating the head 10 while using the difference in rotational moment. When wheelchair users play park golf, the position of the ball is restricted depending on the position of the ball during the game, and there are cases where it is easier to hit the head angle or reverse hand use. The angle adjustment function of the invention makes the game progress smoothly.

  Some Park Golf players may be custom-made to fit their physical function without getting tired of the ready-made Park Golf Club. In order to confirm a club having an angle suitable for oneself (lie angle), if there is no club having an angle adjustment function, it is necessary to prepare and test several different clubs. Then, the intersecting position of the vertical line attached to the shaft 30, the vertical line passing through the center attached to the head surface, and the horizontal line 17 indicating the angle (lie angle) attached to the head upper surface portion becomes a scale indicating the angle. It is possible to check the current angle (lie angle) suitable for you in the book club.
