Description

  The present invention relates to a golf putter.

Conventionally, for example, as shown in FIGS. 9 to 11, in a golf putter (1) comprising a head (2) and a shaft (4) attached to the head (2) via a neck (3), The neck (3) includes a vertical axis (3A) attached to the rear top edge of the blade (2a) of the head (2), and then an axis (3B) bent backward and horizontally as viewed from the batter. Next, an axis (3C) bent upward and inclined in the direction of the hitting ball, next, an axis (3D) bent forward and horizontally when viewed from the batter, and then a shaft (4) A vertical axis (3A) that is attached to the head (2), and a coaxial core that the neck (3) is attached to the shaft (4). Axial axis (3B) and (3C , (3D) rotates the different U-shaped member having leg 90 degrees, is provided configured mounted sideways.
The putter (1) is attached to the head (2) through the neck (3) with the shaft (4) inclined to the batter side at an angle (■) of 10 degrees or more from the vertical axis (V). Therefore, when hitting a ball with the shaft (4), it is said that there is a drawback that the hitting direction is likely to be distorted.

Further, as shown in FIGS. 12 to 13, the head (12) having a semicircular planar shape, and a shaft bent in an arc shape in the direction of the hitting ball with the vicinity of the center of the top end of the head (12) as a fixed end. A golf putter (11) comprising a neck (13) attached in the direction of (14) is provided.
The putter (11) is attached to the head (12) through the neck (13) with the shaft (14) inclined to the batter side at an angle (■) of 10 degrees or more from the vertical axis (V). When hitting a ball with the shaft (14), it is said that there is a defect that the direction of the hitting ball is likely to be distorted.

  In the putter (1) shown in FIGS. 9 to 11, when the ball is hit, the shaft (4) is held and the head (2) is swung in the hitting direction so that the hitting force is coaxial with the tip of the shaft (4). The striking force is transmitted to the upper horizontal axis (3D) corresponding to the U-shaped leg portion of the neck (3) via the core axis (3E), and the striking force is sequentially applied to the neck (3C), Then, it passes through the lower horizontal axis (3B) corresponding to the U-shaped leg and is further transferred to the rising axis (3A) from the head (2) to swing out the head (2) in the hitting direction. become.

  At this time, as shown in FIG. 9, the shaft (4) is attached to the neck (3) at an angle (■) of 10 degrees or more to the batter side from the vertical axis (V). Since the head (2) is easy to rotate around the axis (P) and the strength of the rotational force of the head (2) is not easily transmitted to the batter, the head (2) can be swung out in a predetermined direction. Difficult to hit the ball.

  For this purpose, as shown in FIGS. 9 and 11, the structure of the portion where the neck (3) attaches to the head (2) is such that the vertical axis (3A) at the lowest end of the neck (3) is the head (2). When the batter tries to swing out the head (2) in a predetermined direction by holding the shaft (4), the head (2) Since the rotational force is generated around the vertical axis of the vertical axis (3A) at the lowest end of the neck (3) and becomes the moment of inertia, the batter has the strength of the rotational force of the head (2). Therefore, it is difficult to swing out the head (2) in a predetermined direction, and a deviation in the hitting direction is likely to occur.

  Further, in the putter (11) shown in FIGS. 12 and 13, when the ball is hit, by holding the shaft (14) and swinging out the head (12) in the hitting direction, the hitting force is reduced from the shaft (14). Since it is transmitted to the neck (13) that is mounted curvedly in the opposite direction from the hitting direction, the lower end of the neck (13) is fixed to the substantially central portion of the head (12) having a semicircular planar shape. As for the striking force, there is provided a putter that pushes out the blade (12a) constituting the striking surface from the back surface.

  In this putter (11), the shaft (14) is attached to the neck (13) at an angle (■) of 10 degrees or more to the batter side from the vertical axis (V). The head (12) is easy to rotate around the axis (P), and it is difficult for the batter to transmit the strength of the rotation of the head (12). Therefore, it is difficult to swing the head (12) in a predetermined direction. , The direction of the hitting ball is likely to be out of order.

  For this reason, in the putter (11) shown in FIGS. 12 and 13, when the batter tries to strike the ball in a predetermined direction with the shaft (14), the striking force is the shaft (14). Can be transferred to the head (12) and then to the head (12) to strike the ball, but the upper surface of the curved neck (13) is attached to the shaft (14) in the plane position of the head (12). The position where the lower end of the neck (13) attaches to the head (12) is located at the center of the head (12) in the semicircular shape. In the vicinity. In this case, when the batter tries to hit the ball in a predetermined direction, the head (12) rotates in the horizontal plane around the axis (P) of the shaft (14). Alternatively, the head (12) may be rotated in a horizontal plane around the lower end of the neck (13) attached near the center of the semicircular head (12). In the latter case, The striking force transmitted from the shaft (13) is from the vicinity of the center of the semicircular head (12) toward the blade (12a) of the head (12). ) And acts on the ball striking surface. As shown in FIG. 13, there is a distance (between the plane position of the upper end of the neck (13) and the plane position of the lower end of the neck (13). In addition to this large distance, the structure in which the lower end of the neck (13) is attached to the head (12) is close to a point connection, so the batter holds the shaft (14) and hits the ball. When trying to strike the head, turn the head (12) Contrary to the batter's sensitivity, the direction is free to rotate both left and right around the connection point between the neck (13) and the head (12) as seen from the batter. ) Is difficult to be transmitted, it is difficult to swing out the head (12) in a predetermined direction, and the hitting direction is likely to be out of order.

  As shown in FIGS. 9 to 11, when the batter attempts to hit the ball in a predetermined direction, the head (2) moves in a circular arc shape in the vertical direction before and after the hitting direction. However, as shown in FIGS. 9 and 10, the shaft (4) is attached to the batter side at an angle (■) of 10 degrees or more with respect to the vertical axis (V). Therefore, even if the head (2) is held by the head (2) in order to launch the ball in a predetermined direction, the takeback or stroke at the time of putting is centered on the axis of the shaft (4). The head (2) undergoes a horizontal rotational movement, which makes it difficult to instantaneously detect and suppress the strength of the moment of inertia due to the rotational movement as perceived by the batter, resulting in a deviation in the direction of the ball. Is likely to occur.

  Further, as shown in FIG. 9, as shown in FIG. 9, the batter holds the shaft (4) as another factor causing the generation of the moment of inertia of the head (2) shown in FIGS. 9 to 11. When the ball is to be launched in a predetermined direction, the rotation of the shaft is intentionally stopped, and the head (2) can be moved in an arc shape in the vertical plane before and after the hitting direction. The part 3) attaches to the head (2) is behind the top end of the blade (2a) constituting the hitting surface of the head (2), and is considerably rearward of the center of gravity position in the front-rear direction of the head (2). Therefore, the rotational movement of the head (2) occurs around the axis of the vertical mounting member (3A) at the lowermost end of the neck (3). Instantaneously sense the strength of the moment of inertia as if it were a batter. Win it becomes difficult, tends to occur deviation in the hitting direction.

  In addition, the cause of the rotational movement that acts at the time of hitting is the element of the rotary movement that works around the shaft axis, and the position where the neck attaches to the head is behind the center of gravity in the front-rear direction of the head, and the hitting ball In most cases, the two elements of the rotational movement due to the attachment to the top edge of the blade constituting the surface are combined and work in combination. Therefore, it becomes difficult to instantly detect and suppress the moment of inertia acting at the time of putting due to this as a batter's sense, and it becomes easy to cause a deviation in the direction of the hit ball.

  Accordingly, as shown in FIGS. 1 to 4, the present invention provides a golf putter (21) comprising a shaft (24), a neck (23) attached to the shaft (24), and a head (22) attached to the neck (23). The neck (23) is located on the same axis as the shaft (24), and viewed from the batter, from the rear oblique axis member (23D) to the rear and parallel to the ball striking surface of the head (22) and A member (23C) bent to a horizontal axis, an axis member (23B) bent obliquely downward at an angle attached to the head (22), and behind the head (22) and the head (22) ) And a member (23A) bent in the direction of the ball at the back surface of the blade (22a) constituting the ball striking surface. The structure in which the neck (23) is attached to the head (22) is the head (22). )of Write a provides a golf putter (21) having a socket for securing the neck (23) in the vicinity of the center of gravity in the horizontal plane of 且該 head (22).

  Accordingly, as shown in FIGS. 1 to 4, when the batter tries to strike a ball in a predetermined direction with the shaft (24), the striking force is from the shaft (24) to the uppermost end of the neck (23). Is transmitted to the shaft (24) and the coaxial core member (23E), is parallel to the hitting surface of the head (22) and passes through the axis member (23C) bent rearward as viewed from the batter, It passes through the member (23B) bent in the diagonally lower direction attached to the head (22), and is transmitted to the axis member (23A) bent in the hitting direction attached to the head (22) to hit the head (22). It will swing out in the direction.

  In this case, by providing an axis (23A) toward the direction of the ball at the lowermost end of the neck (23), when the batter tries to hit the ball in the predetermined direction with the shaft (24), The attachment structure at the lowermost end of the neck (23) that supports 22) is the head (2) in the point support of the neck (3) shown in FIG. 9 or the narrow support by the entire cross section of the member cross section of the neck (3). 1) to 4), the lowermost member (23A) of the neck shown in FIGS. 1 to 4 has a thickness of the member of the neck (23) toward the hitting direction of the head (22). In addition to the length of the ball, the batter can support the moment of inertia due to the rotational movement of the head (22), which works at the time of putting, with the long shaft of the lowermost member (23A) of the neck. Take of time Tsu rotational force of the suppression or control acting click and stroke at is facilitated, so that the batter has the effect of it is easy to draw on the head (22) in a predetermined direction.

    Hereinafter, the present invention will be described in detail with reference to Examples 1 and 2.

The present invention will be described with reference to the embodiments shown in FIGS.
As shown in FIG. 1, in a golf putter (21) comprising a head (21), a neck (23) attached to the head (21), and a shaft (24), the neck (23) An axial member (23D) that is attached to the same shaft core as the shaft (24) and is oblique to the rear as viewed from the batter, and a member that is bent rearward and parallel to the ball striking surface of the head (22) (as viewed from the batter) 23C) and the back of the blade (22a) constituting the striking surface of the head (22), the back, and the center of gravity in the horizontal plane of the head (22), or the insertion port of the neck (23) attached to the vicinity of the center of gravity. There is a difference between the member (23B) in the obliquely vertical direction, bent obliquely downward, and the back surface of the blade (22a) constituting the hitting surface of the head (22) in the direction of the hitting ball. To fit Because folded member and (23A) Te has a made structure.

  Therefore, when the batter holds the shaft (24) and tries to launch a ball in a predetermined direction, the striking force is applied to the neck (23) on the same axis that is attached to the shaft (24). , Transmitted to the diagonally inclined member (23D) as viewed from the batter, and then passed through the member (23C) which is parallel to the ball striking surface of the head (22) and bent horizontally, and then hits the ball of the head (22). A member bent downward on the back surface of the blade (22a) constituting the surface toward the insertion port of the neck (23) attached to the rear center of gravity or the vicinity of the center of gravity in the horizontal plane, as viewed from the batter (23B), further transferred to the horizontal member (23A) of the head (22) bent in the hitting direction, behind the blade (22a) constituting the hitting surface of the head (22), the head (22) Horizontal Inner transmitted to the insertion port provided near the center of gravity including the center of gravity, it is possible to draw on the head (22) in the hitting direction.

  In this case, as shown in FIGS. 1 and 3, since the shaft (24) has an angle (■) of 10 degrees or more obliquely rearward when viewed from the batter, the batter puts the shaft (24) on the shaft (24). When taking action, at the time of takeback or stroke, the head (22) tends to rotate left and right as viewed from the batter around the shaft axis. As another factor, when the batter performs a putting action, at the time of takeback or stroke, the head (22) rotates around the attachment position of the neck (23) and the head (22) as viewed from the batter. It is easy to cause. Further, when the batter performs a putting action, the cause of the rotational movement of the head (22) is the element that the head (22) rotates about the axis of the shaft (24), and the neck (23). Then, the head (22) is likely to rotate at a position where the elements that perform the rotational motion of the head (22) are synthesized around the mounting position of the head (22). Since most of the rotational movement of the head occurs at the combined position of the two major elements, the moment of inertia caused by the rotational movement of the head (22) even if the batter tries to launch the ball in a predetermined direction. It is difficult to convey the strength of the batter to the batter's sense, and it is difficult to control and control the moment of inertia.

  Therefore, in the golf putter (21) shown in FIGS. 1 to 4, the neck (23) is attached to the tip on the same axis as the shaft (24), and the rear rear member (23D) as viewed from the batter. The axial member (23C) bent in parallel and horizontally with the ball striking surface of the head (22) and the rear back surface of the blade (22a) constituting the ball striking surface of the head (22), An obliquely longitudinal axis member (23B) bent toward the insertion port of the neck (23) provided in the center of gravity in the horizontal plane or in the vicinity of the center of gravity and directed toward the hitting direction, and the blade (22a) It consists of an axial member (23A) bent in the direction of the insertion port provided on the rear rear surface, and as shown in FIG. 2, the axial member (23C) above the neck (23) is connected to the head (22 ) Parallel to the striking surface On the other hand, the axis member (23A) attached to the head (22) located at the lower end of the neck (23) is a blade near the center of gravity including the center of gravity in the horizontal plane of the head (22). The member (23C) constituting the neck (23) because the head (22) is bent at right angles to the vertical surface in the front-rear direction and bent in the direction of the ball when viewed from the batter on the rear rear surface of (22a). When the head (22) is looked down from above, the member (23A) forms an “L” -shaped virtual axis with each length, so that the batter puts the shaft (24) in the putting. When taking action, it becomes possible to predict the horizontal rotational movement of the head (22) that works by the striking force immediately before entering the stance immediately before the putting action. Exerted by talkback or stroke, to control the rotational movement of the head (22), it is possible to control, batter becomes easy to work out the ball in a predetermined direction.

    Furthermore, the part where the lowermost member (23A) of the neck (23) attaches to the head (22) is near the center of gravity including the center of gravity in the horizontal plane of the head (22), and the member (23A) Because of the thickness and length of the member, the planar shape of the member (23A) constituting the neck (23) is a rectangular shape that is long in the direction of the ball, so the shaft (24) is held to support the head (22). The mechanism to be supported by the thickness and length of the rectangular neck member, and can control the horizontal rotation of the head (22), as well as the bottom end of the neck (23) Since the axial member (23A) located at the right angle with respect to the vertical surface of the ball striking surface of the head (22) is attached with the length of the axial line, the head in the front-rear direction of the head (22) The head (22 The rolling motion of the head (22) that works by the striking force when the batter starts the putting action with the shaft (24) and enters the stance immediately before the putting action can be controlled. Therefore, the batter can easily hit the ball in a predetermined direction.

  In the putter (21) shown in FIGS. 1 to 4, the position where the neck (23) attaches to the head (22) is behind the head (22) as viewed from the batter side. For this reason, when the batter performs the putting action with the shaft (24), the head (22) is supported through the neck (23). Therefore, at the time of putting, the neck (23) and the head ( 22) With the attachment position of 22) as a support point, a balance phenomenon occurs in the head (22) body, and rotational movement tends to occur to the left and right. Therefore, the axial member (23C) constituting the neck (23) is parallel and horizontal to the ball striking surface of the head (22) and has a long axis in the front-rear direction as viewed from the batter, so that it works during hitting. The balance phenomenon of the head (22) can be sensed and controlled by the batter using the length of the member (23C) constituting the neck (23) immediately before the putting action. In the direction, the ball can be easily launched.

The present invention will be described with reference to the embodiments shown in FIGS.
As shown in FIGS. 5 to 8, in the golf putter (31) composed of a head (32), a neck (33) attached to the head (32), and a shaft (34), the neck (33 ) Is attached to the same axis as the shaft (34), and viewed from the batter, the slanted axial member (33D) and then the blade (32a) constituting the hitting surface of the head (32) from the batter An axial member (33C) bent obliquely downward toward the vicinity of the center of gravity, including the center of gravity in the horizontal plane of the head (32), and the ball striking surface of the head (32). Near the center of gravity including the entire center of gravity of the head (32) on the rear surface of the blade (32a) constituting the striking surface of the head (32). In the direction of the hit ball And an axial member (33A) bent toward the striking surface of the head (32) so as to fit the insertion port of the hook (33), and further, the axial member of the neck (33) (33C) is refracted in the middle of the axis.

  Thus, when the batter has the shaft (34) and tries to launch a ball in a predetermined direction, the striking force is on the same axis as the neck (33) attached to the shaft (34). As seen from the batter of the head, it is transmitted to the rear oblique axis member (33D), and then the back surface of the blade (32a) constituting the ball striking surface of the head (32) is viewed from the rear rear side in the horizontal plane of the head (32). In the vicinity of the center of gravity including the center of gravity, it is transmitted to the axial member (33C) bent obliquely downward, and then on the back surface of the blade (32a) constituting the hitting surface of the head (32), The difference between the neck (33) provided in the hitting direction near the center of gravity including the entire center of gravity of the head (32) is transmitted to the axial member (33B) that is parallel to the hitting surface and bent forward in the horizontal direction. To fit the slot, the head ( 2) Difference in the neck (33) provided in the hitting direction on the back surface of the blade (32a) constituting the hitting surface of the head (32) transmitted to the axial member (33A) bent toward the hitting surface of 2) The head (32) can be swung in the direction of the hit ball through the slot.

  In this case, as shown in FIGS. 5 and 7, the shaft (34) has an angle (■) of 10 degrees or more obliquely rearward when viewed from the batter, so that the batter has the shaft (34). When performing a putting action, the head (32) tends to rotate left and right around the shaft axis when viewed from the batter at the time of takeback or stroke. As another factor, when the batter performs a putting action, the head (32) rotates to the left and right as viewed from the batter around the attachment position of the neck (33) and the head (32) during takeback or stroke. It is easy to cause. Furthermore, when the batter performs a putting action, the factors that cause the rotational movement of the head (32) are the elements that the head (32) rotates about the shaft (34), the neck (33) and the head ( 32) At the position where the elements that rotate the head (32) are synthesized around the mounting position of the head (32), the rotation of the head (32) is likely to occur, and most of the rotational movement of the head (32) during putting Occurs at the combined position of the two major elements, so that even if the batter tries to launch the ball in a predetermined direction, the strength of the moment of inertia due to the rotational movement of the head (32) is reduced. It is difficult to transmit to the batter's sense and it is difficult to control and control the moment of inertia.

Therefore, in the golf putter (31) shown in FIGS. 5 to 8, the neck (33) is attached to the diagonally rear member (33D) that is attached to the same axial center tip as the shaft (34), and then the head ( The axial member (33C) bent toward the vicinity of the center of gravity, including the center of gravity of the head (32) in the horizontal plane, on the rear rear surface of the blade (32a) constituting the hitting surface of the head (32), Next, an axial member (33B) that is parallel to the hitting surface of the head (32) and is bent horizontally forward, and then the back surface of the blade (32a) that constitutes the hitting surface of the head (32), An axial member that is bent toward the ball striking surface of the head (32) so as to fit the insertion port of the neck (33) provided in the ball striking direction near the center of gravity including the entire center of gravity of the head (32). (33A) and the neck (3 ) Diagonal longitudinal axis member constituting the (33C) is in a structure the refracted near the middle of the axis.
Therefore, when the batter tries to launch a ball in a predetermined direction using the putter (31), the longitudinal axis member (33B) constituting the neck (33) as viewed from the batter is The batter has the shaft (34) because it is near the center of gravity, including the center of gravity in the horizontal plane of the head (32), is horizontal, and is parallel to the ball striking surface of the head (32). Thus, when performing the putting action for launching the ball in a predetermined direction, the axial member (33B) constituting the neck (33) has a length, so that the rotational movement acting in the horizontal direction of the head (32) is performed. In addition to being able to control using the axis, the axis member (33B) is near the center of gravity including the center of gravity in the horizontal plane of the head (32). 32) The center of gravity axis in the longitudinal direction Rolling phenomenon in the lateral direction acting around the so that it is rectified.
From this, when the batter hits the ball in a predetermined direction with the shaft (34), the batter can predict the rotational movement of the head (32) when entering the putting stance. Since the rotational movement of the head (32) can be controlled, the putting action is stabilized.

  Moreover, as shown in FIG.6 and FIG.8, the shape which combined this axial member (33A) and (33B) which comprises this neck (33) is "L" shape, Each axis line Is composed of an axis parallel to the ball striking surface of the head (32) and an axis parallel to the ball striking direction, and the angle of bending of the “L” is a right angle. Since the batter is in the horizontal plane near the center of gravity including the center of gravity in the horizontal plane of the head (32), when the batter tries to launch the ball in a predetermined direction with the shaft (34), the head (32) “L” -shaped in the form of a combination of the axial member (33A) and the axial member (33B) constituting the neck (33) while having a width and a length in plan view The shape is an imaginary rectangular surface having a width and a length formed by two sides. Therefore, it is possible to predict in advance the horizontal rotational motion that acts during the putting action, and the axial member (32A) attached to the head (32) Since it has an axis that is perpendicular to the surface perpendicular to the ball striking surface and has a length in the direction of the ball, when putting, the axis on the center of gravity in the front-rear direction of the head (32) is the center. The rolling phenomenon of the working head (32) is regulated. From this, when the batter tries to launch the ball in a predetermined direction with the shaft (34), the moment of inertia due to the take-back at the time of putting and the rotational movement of the head (32) that works at the stroke is reduced. Since it is possible to predict and control in the stance immediately before entering the putting action, it is possible to easily hit the ball in a predetermined direction.

  Further, the position at which the neck (33) attaches to the head (32) is located near the center of gravity including the center of gravity axis in the front-rear direction and the left-right direction when viewed from the batter of the head (32). ) Is attached at right angles to the vertical surface of the ball striking surface and directed in the ball striking direction. From this, when the batter tries to strike the ball in the predetermined direction with the shaft (34), the rotational force generated by the putting action becomes difficult to work, so the batter launches the ball in the predetermined direction. It becomes easy.

The embodiment of the present invention has been described with reference to the examples. However, the scope of the present invention is not limited to this, and can be changed or modified in accordance with the purpose within the scope of the claims. Is possible.
For example, the position where the neck attaches to the head may be any part in the front-rear direction as viewed from the batter on the back of the blade constituting the head striking surface. In addition to the above, the neck and the head may be manufactured integrally, or the shaft and the neck may be manufactured integrally.
Further, the angle of the axis lined in the direction of the hitting ball located at the lowermost end of the neck does not limit the mounting at a right angle to the vertical plane parallel to the hitting surface,
In addition, the shape and dimensions of the combination of the axial members that make up the neck, the balance position of the center of gravity changes depending on the structure of the head, so the refraction angle and length of each cram boat member are limited. is not.

  INDUSTRIAL APPLICABILITY The present invention can be used industrially as a putter that allows a player to perform stable putting in a golf round.
