Description

  The present invention relates to a golf putter, and in particular, the length of a putter having a normal shaft length (standard shaft length) can be extended to be easily changed to a long putter (including a medium putter). The present invention relates to a long and short switching type golf putter.

  The length of the shaft of a general golf putter (hereinafter referred to as “standard putter”) is about 31 to 36 inches (usually called 32 to 35 inches), and the length according to the height of the player. Is used. On the other hand, in recent years, putters with long shafts called long putters or medium putters have been used to improve the accuracy of putting and putting technology. These long and medium-sized putters (hereinafter referred to as “long putters”) have a head that moves lower and longer during the stroke, and the fulcrum at the time of the stroke is higher than the standard putter. Since the moment of inertia of the entire putter is increased, the effect of improving the directional stability during putting can be expected. The long putter is also said to be easy to grasp the sense of distance because the position (viewpoint) of the player's eyes is high when putting. In addition, the commercially available long putter has the advantage that the total weight is heavier than the standard putter, so the stroke is slow, the ball core is easy to hit with the putter face core, and the ball rolling is constant. .

Here, when playing golf, the player may want to use the standard putter and the long putter properly according to the condition of the day. For example, a player who uses a standard putter may want to use a long putter when his hand is difficult to touch in winter golf, or when the player is green because of freezing. . However, in this case, it is necessary for the player to carry two clubs having the same purpose and the same function, ie, the standard putter and the long putter, in the golf bag and carry them around during the play. From this point, it is preferable that the function of the standard putter and the long putter can be exhibited with one putter. Therefore, the present inventor has eagerly studied a long putter adapter for golf that can be changed to a long putter by simply changing the length of the standard putter shaft, and to make the golf club shaft extendable and retractable. The technology described in Patent Document 1 has been devised.

Next, the medium size putter as a long putter can be divided into a short length side and a long length side, and the short length side of the medium size putter generally has a shaft length in the range of 36 to 39 inches (medium length). Therefore, it is preferable that the medium-side lie angle θ2 on the short side corresponding to the shaft length is in a range of 72 to 73 degrees as shown in FIG. On the other hand, the long side of the medium-sized putter (what is called a normal medium-sized putter) generally has a shaft length in the range of 40 to 45 inches (medium length). As shown in FIG. 5C, the medium-scale lie angle θ3 on the scale side is preferably in the range of 73 to 75 degrees. Finally, since the long putter generally has a shaft length in the range of 46 to 50 inches (long length), the long lie angle θ4 corresponding to the shaft length is shown in FIG. Thus, it is preferable to set it as the range of 78-80 degree | times. Accordingly, in the case shown in FIG. 5, the standard lie angle θ1, the short side medium lie angle θ2, the long side medium lie angle θ3, and the long side lie angle θ4 are obtained as the hosel 20.

As shown in FIG. 6 (a), in the case of a hosel having a bent portion 22 having a simple bent shape (character shape) that is bent only once between the base end portion 21 and the distal end portion 23, the bent portion 22 is bent. The angle X is a lie angle θ that is an inclination angle of the shaft 30 with respect to the sole of the head 10 (an inclination angle of an extension line of the base end portion 21 of the hosel), and an inclination angle α of the tip end portion 23 of the hosel with respect to the sole of the head 10 ( The total angle (usually 90 degrees) (X = α + θ). Therefore, based on the inclination angle α of the tip 23 of the hosel so that the lie angle θ becomes the standard lie angle θ1, the medium lie angle θ2, the medium lie angle θ3, and the long lie angle θ4, Four types of hosel 20 in which the bending angle X (= α + θ) of the bending portion 22 is set are created and used for replacement. On the other hand, as shown in FIG. 6 (b), in the case of a hosel having a bent portion (crank shape) that bends twice between the base end portion 21 and the distal end portion 23, the entire bent portion 22 is formed. The bending angle X is determined by the bending angle X1 on the distal end portion 23 side and the bending angle X2 on the proximal end portion 21 side (X = X1- (180-X2)). The overall bending angle X determined in this way is the lie angle θ that is the inclination angle of the shaft 30 with respect to the sole of the head 10 (the inclination angle of the extension line of the base end portion 21 of the hosel), and the sole of the head 10. The total angle (X = α + θ) of the inclination angle α (usually 90 degrees) of the tip portion 23 of the hosel with respect to. Therefore, based on the inclination angle α of the tip 23 of the hosel so that the lie angle θ becomes the standard lie angle θ1, the medium lie angle θ2, the medium lie angle θ3, and the long lie angle θ4, Four types of hosel 20 are prepared by setting any combination of the bending angle X1 on the distal end portion 23 side and the bending angle X2 on the proximal end portion 21 side so as to obtain the bending angle X (= α + θ) of the bending portion 22. Try to use a replacement.

  As shown in FIG. 3, the face surface 12 e of the front side portion 12 of the head 10 is not a vertical surface orthogonal to the sole surface (the lower surface in FIG. 3) of the head 10, but slightly tilts backward at a predetermined loft angle β. It is an inclined surface. In FIG. 3, for convenience of explanation, the face surface 12e of the front side portion 12 has an extremely large loft angle, but usually has a loft angle of about several degrees. Here, in the golf putter according to the first embodiment, since the head 10 is configured by assembling the front side portion 12 and the rear side portion 13 with respect to the base portion 11, as the front side portion 11 and the rear side portion 13, Depending on the length (standard length, medium length, long length), multiple types with different shapes, weights, materials, center of gravity, weight balance, etc. are prepared, and the length of the shaft 30 is changed. It can be exchanged according to the situation. That is, the head 10 is prepared by separately manufacturing a plurality of types of front side portions 12 having at least one of a loft angle and a striking surface shape (groove shape) as the front side portion 12. The front side portion 12 of the head 10 is selectively used and attached to the front side of the base portion 11 to constitute the head 10, whereby the striking surface configuration of the head 10 can be changed and adjusted. For example, by changing the length of the shaft 30 from the standard length to the enlarged length and replacing it with the front side portion 12 having a loft angle corresponding to the shaft length, optimal operability can be realized. At the same time, it is possible to realize more optimal operability by exchanging the face surface 12e of the front side portion 12 with a different shape, for example, a face groove having a different position or number. Furthermore, by exchanging the front side portion 12 with a different material for the face surface 12e, the overall weight of the head 10 and the ball touch at the time of impact can be adjusted.

  On the other hand, the head 10 has, as the rear side portion 13, a standard rear side portion 13 having a standard weight and a standard center-of-gravity position, and a length longer than the standard weight and a length different from the standard center-of-gravity position. A long rear side portion 13 having a center of gravity position is separately manufactured and prepared. Then, on the rear side of the base 11 fixed to the lower end of the front end portion 23 of the standard hosel 20, the standard rear side portion 13 is attached to constitute the head 10, and the standard 10 corresponding to the standard length of the shaft 30. We try to get a weight balance. On the other hand, on the rear side of the base portion 11 fixed to the lower end of the front end portion 23 of the long hosel 20, the long rear side portion 13 is attached to constitute the head 10, corresponding to the enlarged length of the shaft 30. A long weight balance is obtained. Thereby, the weight balance of the head 10 can be adjusted between the standard weight balance corresponding to the standard length of the shaft 30 and the long weight balance corresponding to the enlarged length. Specifically, by exchanging the rear side portion 13 of the head 10, it is possible to adjust the overall weight and the center of gravity position (center of gravity depth) of the head 10, thereby realizing appropriate operability according to the shaft length. Can do. For example, by replacing the rear portion 13 with a shape similar to the shape of a tonkachi type or mallet type (a golf putter having a deep center of gravity depth), the center of gravity depth of the head 10 can be deepened. In combination with the shaft 30 having a shaft length that requires (for example, a long putter), optimal operability can be realized. In this manner, by selectively using the standard rear side portion 13, the medium length rear side portion or the long length rear side portion 13 to adjust the overall weight and the center of gravity position (depth of the center of gravity) of the head 10, For example, the shaft length can be changed from a standard length to an enlarged length (medium length, long length), and the weight balance of the golf putter can be adjusted. Therefore, it is possible to make changes in accordance with the player's optimum feeling and operability. Note that the base 11 of the head 10 may be detachable from the hosel 20 so that the base 11 can be replaced to adjust the weight and the position of the center of gravity.

  In addition, in the shaft hole 21a of the hosel 20, as shown in FIG. 4, an adjusting member 25 made of a material such as lead having a columnar shape (a rod having a circular cross section) having the same outer diameter as the shaft hole 21a is detachable. When the golf putter is adjusted between the standard length, medium length and long length by the length adjusting means of the shaft 30, the overall weight and weight balance of the shaft 30 are adjusted. May be. The adjusting member 25 may extend only from the shaft hole 21a of the hosel 20 into the hosel 20, but the lower portion extends into the hosel 20 and the upper portion extends from the lower end opening of the shaft 30 to the inside thereof. You may extend so that it may extend predetermined distance upwards. Alternatively, only the shaft 30 may be extended from the lower end opening to the inside so as to extend a predetermined distance upward. These adjustment members are available in different types with different lengths and weights so that the shaft weight and weight balance is the optimum weight / weight balance when the golf putter is standard length, medium length or long length. Then, a predetermined one is used in accordance with the change in the length of the shaft 30.

  Here, similarly to the concave portion 12b of the front side portion 12, the rear side portion 13 may be hollow by forming a concave portion that opens to the front side, but the rear side portion 13 may be solid. Or the front side part 12 is good also as a solid state which does not have the recessed part 12b. Alternatively, at least one of the concave portion 12b of the front side portion 12 and the concave portion of the rear side portion 13 is filled with an adjusting member made of the same material or another material such as synthetic resin, lead, alloy, etc. for adjusting the weight and weight balance. May be. In this case, the adjustment member may be integrally fixed to the recess 12 b of the front side portion 12 or the recess of the rear side portion 13. However, if the adjustment member is detachably attached, the shape, material, weight, attachment position, etc. of the adjustment member when the shaft 30 is changed between the standard length, medium length, and long length and replaced. By appropriately adjusting, it is possible to adjust the overall weight, the center of gravity position, the center of gravity depth, and the like of the head 10. Further, the base 11 can be formed in a rectangular plate shape in addition to the U-shape shown in the figure. However, if the base 11 is formed in a U shape and an open portion is provided, the single adjustment member can be continuously attached from the front side portion 11 to the rear side portion 13 through the open portion of the base portion 11. It is more preferable in terms of adjusting the center of gravity of the head 10 and the like.

  Further, in addition to removably fixing the front side portion 12 and the rear side portion 13 to the base portion 11 with screws 14, the front side and the rear surface of the base portion 11 and the rear surface of the front side portion 12 and the front side of the rear side portion 13 are mutually connected. Protrusions and recesses that can be engaged and fixed in a concave-convex relationship by close fitting or insertion to each other are formed by integral formation or the like at opposing positions or portions, and the base 11 is engaged by the engagement between the convex portions and the recesses. On the other hand, the front side portion 12 and the rear side portion 13 may be detachably fixed. Alternatively, the base part 11, the front side part 12 and the rear side part 13 may be made of a magnetic material, and the front side part 12 and the rear side part 13 may be detachably fixed to the base part 11 by magnetic force. Alternatively, the front side portion 12 and the rear side portion 13 may be detachably fixed to the base portion 11 with screws 14 by combining engagement and magnetic force by the convex portions and the concave portions. That is, as long as the front side portion 12 and the rear side portion 13 can be easily attached to and detached from the base portion 11, any fastening member other than a screw or any connecting means other than the fastening member can be used. Further, the base portion 11 has an outer dimension smaller than that of the front side portion 12 and the rear side portion 13, and is tightly fitted in the concave portion 12b formed in the front side portion 11 or the concave portion formed in the rear side portion 13, and is completely accommodated. At the time of connecting and assembling, the rear surface of the front side portion 12 and the front surface of the rear side portion 13 may be in close contact with each other. If it carries out like this, while making the head 10 3 piece structure, the external appearance can be made into 2 piece shape.

  The base portion 12 of the head 10 has the same configuration as that fixed to the lower end of the standard hosel 20 and that fixed to the lower end of the long hosel 20, and the head 10 has a shaft as the rear side portion 13. The standard rear side 13 having the standard weight and the standard gravity center position corresponding to the weight balance of the entire head 10 when the length of 30 is set to the standard length, and the length of the shaft 10 are set to an enlarged length. A long side weight 13 corresponding to the weight balance of the head 10 at the time and a long side weight 13 that is larger than the standard weight and has a long center of gravity position different from the standard center of gravity position. is doing. The standard rear side 13 and the long rear side 13 are selectively used and attached to the rear side of the base 12, that is, the rear side of the base 12 fixed to the lower end of the front end of the standard hosel 20. The standard rear side portion 13 is attached to form the head 10, and the long rear side portion 13 is attached to the rear side of the base portion 12 fixed to the lower end of the distal end portion of the long hosel 20. The weight balance of the head 10 is adjusted between the standard weight balance corresponding to the standard length of the shaft 30 and the long weight balance corresponding to the enlarged length.

Embodiment 2
FIG. 7 is an exploded perspective view showing the head and hosel portion of the golf putter according to Embodiment 2 of the present invention.
As shown in FIG. 7, in the golf putter according to the second embodiment, the head 110 is not a three-part and assembly type head as in the first embodiment, but an integrated one. The head 110 may be a substantially prismatic shape, a substantially rectangular parallelepiped shape, an L shape, a pin answer type, a mallet type, a cash-in type, or the like. Specifically, the head 110 is formed with a large-diameter screw hole 111 for hosel extending downward on the upper surface, and a pair of small-diameter screws on the left and right sides of the screw hole 111 (both sides in the length direction of the head 110). The hole 112 is formed to extend downward. On the other hand, the hosel 120 integrally has a base end portion 121, a bent portion 122, and a front end portion 123 similar to the base end portion 21, the bent portion 22, and the distal end portion 23 of the hosel 20 of the first embodiment. The lower end portion of the shaft 30 is detachably attached to the circular opening 121a at the upper end of the end portion 121. Further, the hosel 120 is integrally formed with a male screw 124 at the lower end of the tip end portion 123 via a mounting flange 124 so as to be coaxial. The mounting flange 124 has a pair of band plate shape or rectangular plate shape protruding radially from the boundary portion between the distal end portion 123 and the mounting flange 124, and a small diameter insertion hole 124a is formed through each protruding portion. . Then, the male screw 125 of the hosel 120 is screwed into the screw hole 111 of the head 110, and the screw 14 is screwed into the screw hole 112 of the head 110 via the insertion hole 124a of the mounting flange 124. The head 110 is detachably attached to the lower end. Here, when the male screw 124 of the hosel 120 is completely screwed into the screw hole 111 of the head 110, the male screw 124 and the head are arranged so that the insertion hole 124 a of the mounting flange 124 is aligned with the screw hole 112 of the head 110. The pitch and depth of the screw holes 111 are set. The male screw 124 is not formed at the lower end of the front end portion 123 of the hosel 120, but the male screw 124 portion is formed as a cylindrical insertion portion and has the same circular cross section as the outer diameter of the insertion portion. An insertion hole is formed downward from the upper surface of the head 110, and after inserting the insertion portion of the hosel 120 into the insertion hole of the head 110, the mounting flange 124 is screwed to the head 110 with the screw 14, The head 110 may be detachably attached to the lower end of the hosel 120.

  Here, in the golf putter according to the second embodiment, similarly to the hosel 20 of the first embodiment, a plurality of types of hosel 120 with different bending angles of the bent portion 122 are separately prepared and the shaft length is Corresponding to the change adjustment, a predetermined hosel 120 is used for replacement. Furthermore, the golf putter according to the second embodiment is prepared by separately manufacturing the standard head 110, the medium head 110, and the long head 110 as the head 110. The standard head 110 has a standard weight and a standard gravity center position corresponding to the weight balance of the entire head 110 when the length of the shaft 30 is set to the standard length. Further, the medium-size head 110 has a weight and a depth of the center of gravity corresponding to the weight balance of the entire head 110 when the length of the shaft 30 is set to a medium-size length of the enlarged length, and is larger than the standard weight. It has a middle scale weight and a middle scale center position different from the standard center position. Further, the long head 110 has a weight and a depth of the center of gravity corresponding to the weight balance of the head 110 when the length of the shaft 30 is set to the long length of the enlarged length, and the standard weight and / or It has a longer weight than the middle weight and a longer center of gravity position different from the standard center of gravity position and / or the middle scale center of gravity position. The golf putter according to the second embodiment is attached to the lower end of the hosel 120 by selectively using the standard head 110, the medium head 110, and the long head 110, so that the standard length of the shaft 30 is increased. The weight balance of the head 110 is adjusted between the standard weight balance corresponding to the medium length, the medium weight balance corresponding to the medium length of the shaft 30, and the long weight balance corresponding to the long length. . As described above, the golf putter according to the second embodiment can easily adjust the overall weight and the position of the center of gravity (depth of center of gravity) by exchanging the entire head 110, and can be replaced with the head 110 corresponding to the shaft length. Optimal operability can be achieved. In addition, the head 110 can easily change the striking surface configuration by making the striking surface configuration different among a plurality of types of heads.

  Here, the head 110 may have a plurality of screw holes (or insertion holes) 111 formed in the length direction of the head 110. In this way, the male screw (or insertion portion) 125 of the hosel 120 is selectively screwed (or inserted) into one of the plurality of screw holes (or insertion holes) 111 of the head 110, thereby The effective hitting surface range 110 can be changed freely. In this case, the screw hole (or insertion hole) 111 of the head 110 is selectively selected according to the exchange of the shaft 30 between a standard length and an enlarged length (medium length, long shape). You may make it use for. In any case, a suitable impact range (effective hitting surface) of the head 110 at the time of putting changes. For example, when the hosel 120 is attached to the screw hole (or insertion hole) 111 on the toe side in the length direction of the head 110 or the screw hole (or insertion hole) 111 on the heel side, the effective striking surface of the head 110 is This is a wide range between the position of the center of gravity of the head 110 and the extension line of the central axis of the shaft 30. On the other hand, for example, when the hosel 120 is attached to the central screw hole (or insertion hole) 111 of the head 110, the effective striking surface is narrow between the center of gravity of the head 110 and the extension line of the central axis of the shaft 30. It becomes a range. When the toe side or heel side screw hole (or insertion hole) 111 is used, the effective striking surface of the head 110 is widened, but the face surface is easily opened during the putting stroke. On the other hand, when the screw hole (or insertion hole) 111 at the center of the head 110 is used, the face surface of the head 110 does not open during the putting stroke, but the effective hitting surface becomes small. The screw holes (insertion holes) 111 of the head 110 that are not used may be removably filled with plug members having the same shape.

  Here, when the golf putter shaft length is an enlarged length and the long putter is used, the player generally operates the golf putter with only the right hand using the left hand as a fulcrum when putting. Further, at this time, the shaft length becomes an enlarged length, and the total weight increases due to the replacement of the head 110, so that the moment of inertia acts relatively large, and the stroke becomes slow and stable. Therefore, in this case, the player can accurately impact the golf ball in the vicinity of the center of the effective hitting surface of the head 110. Therefore, even if the effective hitting surface is small, the central screw hole (insertion) that makes it difficult to open the face surface during the stroke Hole) 111 is preferably used. On the other hand, when a golf putter shaft length is used as a standard length and a standard putter is used, a general player may remove the center of the effective hitting surface when putting. Therefore, the toe side or heel side screw can increase the effective hitting surface. It is preferable to use a hole (insertion hole) 111. The golf putter thus configured can realize optimum operability according to the shaft length by selectively using any of the three screw holes (insertion holes) 111 of the head 110.

As shown in FIG. 18, the golf putter according to the twelfth embodiment integrally accommodates and fixes the filling member 1120 having the same configuration as the filling member 1020 to the head 1010 of the eleventh embodiment. Are the same as the insertion holes 611 and 613 of the head 610 of the eighth embodiment at two positions (toe side or heel side of the sole) that are close in the length direction of the head 1010 (filling member 1120). 2) insertion holes 1121 and 1122 are formed. As in the eighth embodiment, the insertion holes 1121 and 1122 of the head 1010 have insertion angles γ1 and γ3 set so as to form the standard lie angle θ1 and the long lie angle θ3, and the lower end of the hosel. Is attached and detachably held and fixed.

  Incidentally, the lie angle changing means of the golf putter according to the present invention, as described in the above embodiment, can be used for a plurality of types of hosel with different bending angles of the bent portions, or with different insertion angles of the hosel. A plurality of formed insertion holes, or a combination of the hosel and the insertion hole of the head, can be configured. You may comprise so that an angle change is freely possible between the lie angles for a scale. In the hosel according to the first to seventh embodiments of the present invention, the crossing angle formed by the extension line of the base end portion with respect to the sole of the head matches a predetermined angle such as a standard lie angle or a long lie angle. As long as it does, it can have any number (one or more) and shapes (bending, bending, multi-step bending / curving, etc.) of bent portions or bent portions. That is, as shown in FIG. 6A, when the lie angle is θ (degrees) and the lower end of the hosel is fixed to the head, the extension angle of the lower end portion of the hosel is an intersection angle formed with the sole of the head. The bending angle of the bent portion of the hosel is set so that the bending angle X (degree) of the bent portion of the hosel becomes α (degree) + θ (degree) when the mounting angle of the hosel with respect to the head is α (degree). (X = α + θ). As shown in FIG. 6B, when the hosel has a plurality of bent portions, the predetermined angle x (degrees) determined according to the bent angles x1 and x2 of the plurality of bent portions is the α (degrees). ) + Θ (degrees), the bending angle of the plurality of bent portions of the hosel is set (x = x1− (180−x2) = α + θ).

  Specifically, as shown in FIG. 6A, when the hosel has only one bent portion between the base end portion and the tip end portion, the lower end of the tip end portion is orthogonal to the sole of the head ( In the case of attachment (at 90 degrees), the bending angle x of the bent portion between the distal end portion and the proximal end portion is set to x = 90 degrees (α) + the lie angle (θ). For example, when the lie angle (θ) = 80 degrees and the mounting angle (α) = 95 degrees, x = 80 + 90 = 170 degrees (case 1). Also, when the tip of the hosel is fixed to the head at an attachment angle (α) exceeding 90 degrees, the bending angle x = the attachment angle (α) + the lie angle (θ) is set. For example, when the lie angle (θ) = 80 degrees and the mounting angle (α) = 95 degrees, x = 80 + 95 = 175 degrees (case 2). When the total angle x of the mounting angle (α) and the lie angle (θ) is 180 degrees (for example, when α = 100 degrees and θ = 80 degrees), the bending angle x = 180 degrees, and the hosel Means a straight line. Therefore, in this case, the hosel has no bending angle as a whole, but this is different from the embodiment in which the insertion angles of the plurality of insertion holes are made different in the head as in the above eighth to twelfth embodiments. It will be similar. In the case 1 described above, when there are a plurality of hosel bent portions, the bent angle x1 of the first bent portion (lower end side) is 260 degrees, and the bent angle x2 of the second bent portion (upper end side). Is 90 degrees, the bending angle x of the entire hosel is x = x1− (180−x2) = 260− (180−90) = α + θ = 80 + 90 = 170 degrees.

  Further, when the lie angle adjusting means of the present invention is constituted by a hosel, the hosel is detachably attached to the lower end of the shaft and linearly extends from the central axis of the shaft, and a predetermined fixing angle to the head. So long as it has a distal end portion that is detachably attached or integrally attached and a bent portion (including a curved portion) that integrally connects the base end portion and the distal end portion, The lie angle adjusting means includes a plurality of types of hosel with different bending angles (including curvature) of the bent portion. Further, in this case, the plurality of types of hosel are such that at least the lie angle, which is the intersection angle of the head sole with respect to the central axis of the shaft, becomes the standard lie angle, that is, the extension line of the base end portion with respect to the head sole. The standard hosel where the bending angle of the bent part is set so that the crossing angle becomes the standard lie angle, and the bending angle of the bending part is set so that the crossing angle of the extension line of the base end part to the sole of the head becomes the long angle. What is necessary is just to include the set long hosel.

  Further, the golf putter according to the present invention attaches the hosel detachably to the tip of the shaft, and when the insertion hole of the head is used as the lie angle adjustment means, the hosel is fixedly attached to the shaft. It is also called a neck or a socket, and is not limited to the illustrated one. That is, the hosel is a portion that is provided at the tip (lower end) of the shaft and connects the shaft and the head, and can have any shape and configuration as long as it has the characteristics of the present invention. The head is detachably attached to the tip of the hosel, or a part of the head is fixedly attached and the other part is detachably attached to the part. The head is not limited to the illustrated one. Further, the lie angle adjusting means is provided in at least one of the hosel and the head, and if the lie angle, which is the intersection angle of the head sole with respect to the central axis of the shaft, can be variably adjusted in a plurality of stages, the above can be set. Those other than the embodiment can be used.
