JP4491799B2 - Joining member and golf putter using the same - Google Patents

Description

  The present invention relates to a member for joining two parts, and a golf putter having a structure in which an angle formed by a shaft and a head is variable by using the member.

  As is well known, a putter, a type of golf equipment, is used when a golf ball rolls and sinks in a cup embedded on a lawn called green. It is no exaggeration to say that the results are determined by accurately grasping and how to properly handle the putter. Therefore, golf players are trying to get putters that fit their preferences as much as possible. However, since commercially available putters are standardized to some extent in shape, weight, etc., players have not always been able to meet a putter that suits their preferences.

  By the way, factors that determine the compatibility between the player and the putter include the angle between the shaft and the head in the putter (hereinafter referred to as the lie angle) and the shape of the head. As a technique corresponding to this, Patent Document 1 discloses a putter having a structure in which a head can be rotated and a screw is used for fixing the head via a pin provided at a connection portion between the head and the shaft. Yes.

  This putter can be adjusted to the desired lie angle according to the player's preference, but since the head itself is pivotally supported by the shaft portion, it is difficult to remove and replace with another head. The characteristics resulting from the shape and weight of the material cannot be changed. Therefore, it is difficult to cope with the turf state, and it remains difficult to handle. Further, since only the screw is used for fixing the head position, it is conceivable that the lie angle deviates from a desired position due to an impact such as contact with the ground.

  Accordingly, an object of the present invention is to provide a joining member that can change the angle formed by two components in a detachable state and that does not easily deviate from the set angle. The object is to provide a golf putter with a variable angle.

  The present invention has been made as a result of examining a structure for joining two parts in order to solve the above-mentioned problems.

  That is, the present invention provides a first member in which a plurality of gear-shaped first concavo-convex portions are formed on the outer peripheral side of a cylindrical member protruding on a flat plate substantially parallel to the center line of the cylindrical member. And a coupling member having a second member in which a flat plate is provided with a hole in which a second concavo-convex portion having a shape that fits into the first concavo-convex portion is provided on the inner periphery. A curved surface forming a concentric cylinder with the cylindrical member is formed in at least a part of a position facing the outer peripheral side of the cylindrical member, and the first cylinder is in an angular range formed by an end portion and a center of the curved surface. The same number of gear-shaped third concavo-convex portions as the first concavo-convex portions formed in the same angle range are formed, and the second member is fitted to the third concavo-convex portion. A joining member characterized in that a fourth uneven portion having a shape is formed.

  In the present invention, a curved surface that forms a concentric cylinder with the cylindrical member is formed at least at a part of the first member facing the outer peripheral side of the cylindrical member, and an end portion and a center of the curved surface are formed. In the angle range formed by the second cylindrical member, the same number of gear-shaped third concavo-convex portions as the first concavo-convex portions formed in the same angle range in the first cylindrical member are formed. Further, a fourth uneven portion having a shape that fits with the third uneven portion is formed.

  Further, the present invention is the golf putter characterized in that the shaft and the head are detachably joined by the joining member, and the angle formed by the shaft and the head is variable.

  The joining member of the present invention has a structure in which a gear-shaped groove, that is, an uneven portion, formed substantially parallel to the movable shaft is fitted, so that the angle formed by the two parts can be set within a certain range and is joined. The component does not rotate around the movable shaft. Therefore, by applying this joining member to joining of the shaft and the head, a golf putter capable of adjusting the lie angle within a certain range and exchangeable with a desired head can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view of a joining member according to an embodiment of the present invention. In FIG. 1, 1 is a first member, 2 is a second member, and 3 is a hexagon socket head cap screw for locking the first member and the second member.

  Moreover, FIG. 2 is a figure which shows the detail of a 1st member, (a) is a front view, (b) is AA sectional drawing. In FIG. 2, 4 is a 1st uneven part, 5 is a 3rd uneven part, 6 is a female screw, 7 and 8 are sliding surfaces with the corresponding surface in a 2nd member.

  3A and 3B are diagrams showing details of the second member, in which FIG. 3A is a BB sectional view and FIG. 3B is a front view. In FIG. 3, 9 is a 2nd uneven part, 10 is a 4th uneven part, 11 is a through-hole for inserting a volt | bolt, 12 and 13 are sliding surfaces with the corresponding surface in a 1st member. .

  In this example, the 1st uneven part 4 formed in the outer peripheral side of the cylindrical member in FIG. 2 fits the 2nd uneven part 9 in FIG. 3, and the 3rd uneven part 5 in FIG. 3 is configured to be fitted to the fourth uneven portion 10 in FIG. Moreover, since the number of the first uneven portions is 24, the angle formed by the two members can be set and fixed every 15 °. Needless to say, the settable angle can be changed by changing the number of the concave and convex portions.

  And since the internal thread 6 is provided in the 1st member 1 side and the through-hole 11 for inserting a volt | bolt is provided in the 2nd member 2 side, in the state which fitted the two members Locking by screwing is possible. For this reason, the angle formed by the two members can be set with a constant adjustment width in a state where the angle does not change, and it is extremely easy to separate the two members by removing the bolt. Moreover, if a hexagon socket head cap screw is used for locking as shown in FIG. 1 and a hole is provided on the side through which the bolt is inserted, the head of the bolt is not exposed to the outside, which is advantageous in appearance. .

  FIG. 4 is a schematic view showing an example of a golf putter using the joining member of the present invention for joining the head and the shaft. In FIG. 4, 15 is a joining member, 16 is a shaft, and 17 is a head. Since the joining member 15 used in the golf putter shown here has the structure as described above, the angle formed by the shaft 16 and the head 17 can be adjusted within a certain range, and is firmly fixed in use. Moreover, the replacement of the head 17 is extremely easy.

  As described above, according to the present invention, a joining member that can firmly join two parts in a state where the angle between the two parts can be adjusted, and the angle between the shaft and the head can be adjusted by using the joining member. A golf putter can be provided. As a result, the golf putter can be adapted to the user's preference, and its convenience can be enhanced.

  It should be noted that the present invention is not limited to the specific examples described above, and any design changes that do not depart from the gist of the present invention are included in the present invention. In other words, the present invention includes various modifications and corrections that can be conceived by those having ordinary knowledge in the technical field, and those applied to other than the golf putter are also included in the present invention.

  The perspective view of the joining member in connection with embodiment of this invention.   The figure which shows the detail of a 1st member, FIG. 2 (a) is a front view, FIG.2 (b) is AA sectional drawing.   The figure which shows the detail of a 2nd member, Fig.3 (a) is BB sectional drawing, FIG.3 (b) is a front view.   Schematic which shows the example of the golf putter which used the joining member of this invention for joining of a head and a shaft.
