Description

  This invention makes the face side and the center part light, and increases the weight of the heel side on the left and right sides of the main body and the rear side on the toe side, so that the face is completely tight and the sweet spot depth is reduced. The present invention relates to a golf putter that is deepened to the maximum, eliminates chattering of the head face during putting, improves the straightness of the head, and performs putting with excellent directionality.

  Conventionally, in order to improve the straightness of the ball and the sense of distance when putting, the head design of the putter and the material to be used are selected according to the human sense and technology.

  By the way, the conventional head can be seen with a substantially uniform weight distribution along the length direction of the face part, and a pattern with a structure in which weights are distributed to the center rear part and both end parts of the face. Yes.

  These putters have improved the direction of movement with respect to the shot direction, but even if the player tries to make a shot with the face diagonally facing the target line, the depth of the face sweet spot is shallow, and the center and rear ends Even if there is a weight, it is not possible to obtain a perfect effect, and subtle chattering on the face appears on the face, making it difficult to put the ball into the hole.

  In addition, a metallic head such as stainless steel or aluminum has a large instantaneous repulsive force against the ball when putting, and the ball rolling direction varies depending on a slight angle shift or the contact of the rimples around the ball. A thin plate of rubber or synthetic resin is affixed to the hitting portion, but there is a problem that it is difficult to hold the true direction because the plate is thin.

  Therefore, the subject of the present invention is repelled by gently receiving the ball hitting as the stress of the entire wood portion of the head body. Therefore, the head body is made of wood, the middle part of the face is thin, the heel and the toe side extend rearward, and the gate-shaped rear part is provided with a metal weight with high specific gravity. It is an object of the present invention to provide a golf putter that can perform putting with excellent directionality by improving straight running performance without causing chatter and generating straight running inertia.

In order to solve the above problems, according to the present invention, in a putter provided with a head at the tip of a shaft, the head is formed in a planar gate shape by providing an extension extending rearward at both end portions of the face portion. This occurs from the rear weight part by embedding weights at the positions of the rear end parts of the two extension parts, fixing a bottom plate for improving slippage on the lower face of the face part and the extension part, and making the last part a shoe shape. Prevent damage. In addition, by using a groove provided on the upper surface of the face portion so as to be parallel to the face surface, the sweet spot is displayed even if the short, medium, long or grip weight of the shaft changes. Adjust the position of the member.

  Here, oak or teak is used as the hard wood formed by the head so that the natural ball repulsive force of the wood can be obtained on the face surface, and the weight provided at the rear end of both extensions Due to the staggering effect, the direction of movement with respect to the shot direction is maintained, the head does not shake, and the straight inertia of the ball hitting the sweet spot can be obtained.

  When a ball is applied to a sweet spot by a pendulum hitting method with the correct direction, the face does not become wrinkled due to the effect of the left and right rear portions, and the ball has a structure that gives directionality and excellent straight inertia to the ball.

  In addition, the face and head body are made of wood, so when they hit the ball, the impact is gently transmitted to the entire xylem, and the face maintains its directionality due to the staggering effect of the pendulum, and the ball goes straight in the desired direction. Can be rolled into.

  According to the present invention, the head is formed in a flat gate shape with the extension portions extending rearward at both side end portions of the face portion, and the weights are embedded at the positions of the rear end portions of the both extension portions. The head has a gentle effect due to the weight provided at the position of the rear end, maintaining the direction of movement with respect to the shot direction and preventing the head from shaking, improving the straightness of the head when putting and improving the direction. Putting can be done.

  Also, the sweet spot display member is fixed to the upper surface of the face portion with a nail or an adhesive so that the position of the sweet spot display member can be selected by using a groove provided on the upper surface of the face portion so as to be parallel to the face surface. In the case of wooden, even if there is a difference in the position of the sweet spot due to the non-uniformity of the material, the fixed position of the display member can be set according to the sweet spot found after total assembly.

  In particular, the putter is required to deform short, medium, and long shafts and grips, and the direction of each changes. The groove on the upper surface of the face portion is provided on the upper surface of the face portion so as to be parallel to the face surface. Since the sweet spot display member is used after being adjusted in position, the adjustment slide type sweet spot display member is effective.

  Furthermore, since the weight of the back surface of the head main body and the left and right gate-shaped rear portions are fixed with a shoe-shaped integrated bottom plate, even if the head main body is made of wood or a weight is inserted from the bottom of the rear portion. The integrated reinforcement plate strengthens the head body and improves the strength of the head and the slipperiness of the movement in the shot direction, and also gently distributes the stress to the entire xylem, thereby The direct direction and the direct direction of the ball become familiar, and an accurate putt is obtained.

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

  As shown in the figure, the putter 1 is configured by providing a head 3 at the tip of a shaft 2, and the head 3 is provided with extensions 5, 5 extending rearward at both end portions of a face portion 4 that is long in the front-rear direction. It is formed in a planar gate shape, and a weight 6 is embedded at the position of the rear end portions of the extension portions 5 and 5.

  Examples of the material used for forming the head 3 include various metals such as stainless steel and aluminum, and hard wood. For example, it is preferable to use oak or teak as hard wood. By cutting out into a mold, the thickness of the central portion of the face portion 4 is reduced, the extending portions 5 and 5 extend linearly from both side end portions of the face portion 4 to the rear, and the central portion of the head 3 has a large recess R portion. By reducing the weight of the central portion to 7, it is possible to further enhance the effect of the smoothness due to the weights 6 provided at the positions of the rear end portions of the extension portions 5 and 5.

  A metal bottom plate 8 is attached and fixed to the lower surface of the face portion 4 and the extension portions 5 and 5 of the head 3, and the portion of the bottom plate 8 positioned on the lower surface of the extension portions 5 and 5 is placed behind the extension portions 5 and 5. The shoe-shaped case portion 8a covering the end side is provided, and the strength is obtained by wrapping the rear ends of the extension portions 5 and 5 with the weights 6 like shoes regardless of the direction of the grain of the head 3 using hard wood. We are trying to keep it.

  The weight 6 may be installed by being embedded and fixed in a hole provided from the rear end side or the lower surface side of the extension parts 5 and 5 and having a weight required by setting a material or a size having a high specific gravity. .

  A groove 9 that is long in the front-rear direction parallel to the face surface 4 a and a mounting hole 10 for the shaft 2 are provided on the front side of the upper surface of the face portion 4 of the head 3. The display member 11 is attached so that the position can be selected by sliding.

  The display member 11 is formed by forming a fitting plate 13 into the groove at a right angle on the front edge of the display plate 12 having a mark 11a such as an arrow on the upper surface, and selecting and displaying the position in the length direction of the groove 9 The plate 12 is fixed to the upper surface of the face portion 4 by using wood screws or nails or by bonding.

  Since the wood forming the head 3 has a variation in wood quality, the position of the sweet spot on the face surface 4a varies even if the wood is cut into the same size and shape. For this reason, the shaft 2 having a predetermined length is used. After the attachment, the position of the sweet spot in each head 3 is found comprehensively, and then the fixed position of the display member 11 may be set in accordance with the sweet spot, along the length direction of the groove 9. You can respond by sliding and selecting the position.

  The putter of the present invention has the above-described configuration, and it is only necessary to grip the shaft 2, align the mark 11a of the display member 11 with the ball, perform a favorite swing such as a pendulum hitting method, and put the ball at a sweet spot. The head 3 attached to the tip of the shaft 2 is formed in a planar gate shape by providing extension portions 5 and 5 extending rearward at both end portions of the face portion 4, and the rear end portions of the extension portions 5 and 5 are formed. Since the weight 6 is embedded in the position, the head 3 is light in the center part on the face side and heavy on the rear side, and the weight 6 provided at the positions of the rear end parts of both the extension parts 5 and 5 makes the head 3 have a gentle effect. The head 3 is not shaken without shaking and the head 3 is not shaken, and the head 3 can be moved straight at the time of putting.

  Further, by making the head 3 wooden, a natural repulsive force can be obtained when the ball hits the face surface 4a, and the true direction can be maintained.
