Description

  A head position adjuster comprising a reflector or a reflector and a leveler is magnetically attached to the upper part of the golf club putter head, and the head position of the putter at the time of addressing using the putter is determined. The present invention relates to a head position adjuster that enables indirect viewing of the positions of both eyes above the ball through the mirror surface of the reflecting mirror, and a putter putting practice tool provided with the adjuster.

  When addressing using a conventional putter, whether or not the position of both eyes (heads) above the ball, which is a general base, is vertically above the ball or a specific position near the ball, and the direction connecting the eyes is a line It was almost difficult to instantly grasp whether or not it was parallel to (the direction in which the ball rolls).

  For example, the mirror surface provided on the head shown in Japanese Patent Application Laid-Open No. 2000-210397 and Japanese Patent Application Laid-Open No. 10-24125 is a mirror surface direction for indirectly viewing (projecting) the rolling direction surface (image) of the ball. It is difficult to determine whether the ball is parallel to the rolling direction line and whether the position of both eyes is in front, back, left, or right with respect to the lower ball.

  Further, for example, the orientation of the two circular mirrors provided on the upper part of the head of Japanese Patent Application Laid-Open No. 2006-110029 has no reference for the orientation of the putter, and the orientation based on the loft angle and the lie angle of the putter and the circular mirror It is difficult to make adjustments that are consistent with the orientation, and it is difficult to attach and detach the circular mirror, making it unsuitable for using the game of the putter itself.

  In addition, for example, in FIGS. 1 to 5 of Japanese Patent Laid-Open No. 59-131379, the upper eye position is indirectly viewed with an eye alignment mirror that is perpendicular to the front flange front surface corresponding to the vertically arranged putting surface. Then, if the position of the eye is not located considerably behind the ball, the eye cannot be visually observed, and is limited to be different from the general position of the eye above the ball. In addition, it seems that the target path reflected on the ball / target matching mirror has the effect of making it easy to align the putting surface with the target path. It is not suitable for setting directly above, and it seems that the patting position is limited to the position where the pin 42 is set in the hole 41. In the embodiment of FIG. 7, the eye aligning mirror has the same function as the eye aligning mirror, and the ball / target aligning mirror aligns the target path with the boundary line with the eye located far behind the ball. If the practice of hitting the ball in front of the flange is repeated, the hit feeling and the subtle feeling of the repulsive force required in the design of the putter itself may be different, which may adversely affect the putting in the game.

  Further, for example, a mirror of 45 degrees with respect to the vertical direction of the face disclosed in Japanese Patent Laid-Open No. 2000-185121 is for viewing an image of a golf ball, a ball hitting point target portion, and a rolling direction surface of the ball. Are separated, and it is difficult to adjust the angle of the mirror in the 360-degree rotation direction with respect to the level of the level, so the position of the upper eye is unclear.

  Also, for example, in Japanese Patent No. 2566535, if the reflecting mirror provided on the upper part of the head is inclined at 45 degrees so that the target image reflected on the mirror surface is reflected by the upper player's eyes, the direction of the head of the putter is set to a predetermined horizontal direction. It seems to be the most important, although it seems to have the advantage of keeping the player's head right above a certain position and the ability to easily align the face in the target direction with the target image reflected on the reflector It seems difficult to set the direction of both eyes parallel to the target line and to grasp the position of the upper head (both eyes) with respect to the lower ball, so that it is not suitable for acquiring a posture of a certain address. In addition, there is a problem that a plurality of different shapes of the mounting portion of the apparatus must be prepared depending on the shape of the head.

  Further, for example, the mirror of the special table 2002-511788 is an image of the target line. If the putter alignment assisting tool is mounted so as not to overlap the face that does not interfere with putting, the aiming member behind the mirror is fixed from the ball position. It is located on the rear side that is spaced apart, and the position of the eye for aligning the aiming member is also limited to the rear of the ball. Then, it is difficult to obtain accurate accuracy when aligning from a certain height, and it is impossible to make both eyes parallel to the target line without aligning both eyes alternately. In addition, the structure is complicated and is not practical.

  In any of the above except the above paragraph (0004), the angle of the mirror surface is adjusted in order to capture the target image on the mirror surface (it seems to be approximately 45 to 50 degrees with respect to the topographic surface). In the case of flat (horizontal) or descending slopes or climbing slopes, it is difficult to correctly project the necessary target image on the mirror surface unless the angle of the mirror surface is adjusted in accordance with the topography. For example, in the posture of an address in a club other than the putter, the body is basically tilted in accordance with the inclination of the ground (the body is tilted to the right when the left leg is inclined upward), but the putter is basically in an upright posture regardless of the terrain. Therefore, if you try to capture an image on the mirror surface without adjustment, the face (mirror surface) is placed in the launch direction when putting on downhill terrain, and if the head position is not shifted in the launch direction, the target image reflected on the mirror surface is viewed indirectly. It cannot be done and it becomes an irregular posture. Therefore, it seems that the angle adjustment of this mirror surface is troublesome and inconvenient in practice to improve the putting technology in various terrain.

  JP2000-210397   JP 10-24125 A   JP2006-110029   JP 59-131379   JP 2000-185121 A   Patent No. 2566535 (Japanese Patent Laid-Open No. 7-299181)   Special table 2002-511788

  It seems that the effect that makes it easy to align the putter in the target direction is obtained only when practicing using the conventional mirror that mirrors the target image described above, but it is difficult to think that the effect can be obtained when playing a game without using a mirror. At the time of the putter address, it is difficult to grasp the position of both eyes (heads) above the ball or a specific position near the ball, so both eyes are parallel to the line and directly above the line. It was difficult to perform effective practice of wearing a basic posture that always set the eye position constant, aiming to improve the putting technique quickly and accurately.

  The present invention is intended to solve such a conventional problem. The most important at the time of addressing is to make both eyes parallel to the line, and to place both eyes directly above the line. The orientation of the head is set to a standard orientation in design, the head position adjuster of the present invention is simplified to be one-touch detachable and easy to carry, and the head position adjuster is attached. It is possible to attach the head position adjuster and its head position adjuster, which makes it possible to make the putter structure simple and without impairing the performance, so as not to hinder the use of the putter itself during the game. It is an object of the present invention to provide a putter practice tool comprising a putter on which the head position adjuster is mounted.

  In order to achieve the above object, the head position adjuster and putter of the present invention have a flat face on the front surface and a flat upper surface of a certain width at the lower end of the shaft of the long bar body having the upper end as a grip portion. Or a block-like head having a flat vertical surface of a certain width that is back-to-back with the face and a sweet spot portion that becomes a hitting point for hitting the ball on the face, and between the sweet spot of the face and the back surface of the head at the end. A head of a putter that has a head axis and the longitudinal direction of the face is perpendicular to the head axis. When the putter head is placed on a horizontal plane, the horizontal plane including a reference line of a lie angle and the shaft When the lie angle of the angle, the reference line of the loft angle upright with respect to the horizontal plane, and the loft angle of the opening angle between the reference line and the face are designed angles, The head position adjuster provided on the upper surface of the head or the flat vertical surface of the head includes a reflecting mirror having an upward mirror surface inclined obliquely upward from the front on the face side toward the rear on the head back side. A configuration comprising a mounting member serving as a mounting means to the head of a putter provided with a mounting magnet mounted in front of the reflecting mirror, and the rear of the reflecting mirror extending rearward on the mounting member A holding member for mounting and holding (arranging) all of the reflecting mirror shown in FIG. 7 or FIG. 7 is provided in an integral structure, and the reflecting mirror is formed by the holding member and the mounting member and is open upward. The mirror surface has an inclination angle of a predetermined inclination angle that allows both eyes to be indirectly visible by copying both eyes onto the mirror surface at an address of 0 degrees 30 minutes or more and within 5 degrees with respect to the horizontal plane. The lower surface of the mounting member or the mounting Forming a positioning unit of the head in a configuration in which a flat magnetically attached mounting portion for magnetically attached attached to the rear head top or head wood front. (See Figure 1)

A leveler provided with a ferromagnetic material can be magnetically attached to the mirror surface near the attachment magnet provided in the attachment member. (See Figure 1)
In another level mounting method, the reflecting mirror is mounted on the upper part of the mounting member (see FIGS. 4 to 7 and FIGS. 10 to 15) or the rear upper part of the holding member (see FIGS. 8 and 9). A leveling device is arranged in series with the reflecting mirror in the tilt direction.

  Angle adjusting means is provided for adjusting the tilt angle of the mirror surface of the reflecting mirror to a predetermined tilt angle with respect to the holding member on the back side of the reflecting mirror. In an embodiment of the angle adjusting means, an inclination inclined in one of the front and rear directions of the reflecting mirror between the reflecting mirror and the mounting member and the holding member or between the reflecting mirror and the holding member. It is set as the structure which provided the board. (See Figs. 8 and 9)

  Further, in a modification of the angle adjusting means, a plate-shaped spring and a screw hole are formed in the holding member between the reflecting mirror and the mounting member and the holding member, or between the reflecting mirror and the holding member. Provided in the same screw hole and provided with a push bolt, the spring has a long square plate shape that is long in the front and rear directions on a plane, and has a falling portion (base) at the front end portion of the long square plate shape. An L-shaped, lower end of the base of the spring located below the front part of the reflecting mirror is fixed to the mounting member or the holding member, and the reflecting mirror is mounted and fixed on the upper surface of the spring. The push bolt positioned slightly rearward from the lower (back side) center portion is configured such that the upper end of the push bolt is in contact with the lower surface of the spring, and the reflecting mirror is used with the front fixed portion of the spring as a fulcrum. Rotate up and down with a push boltThe spring acts when the reflecting mirror rotates (when the tilt angle is adjusted) and when it is stationary. (See FIGS. 10 to 12)

  Further, in a modification of the angle adjusting means, the first ferromagnetic body disposed on the upper surface of the mounting member or the holding member, and the rear surface of the reflecting mirror opposed to the first ferromagnetic body. A second ferromagnetic body that can be magnetically attached to or absorbed by the first ferromagnetic body, and screwed into a screw hole penetrating the holding member behind the first ferromagnetic body, A push bolt provided so that a tip thereof is in contact with a contact plate attached to the back surface of the reflecting mirror, and at least one of the two ferromagnetic bodies is a magnet, and the ferromagnetic body is The reflecting mirror is fixed to the mounting member or the holding member, and the reflecting mirror is pivotally moved up and down by the push bolt to be held in a stationary manner. Adjust the tilt angle of the mirror surface. (See FIGS. 13 to 15)

  On the mirror surface of the reflecting mirror, a virtual center line is placed in the direction of inclination of the mirror surface, and at least a part of both side surfaces sandwiching the center line among the lower end side surfaces of the mounting member having a magnetic attachment mounting portion on the lower surface In order to attach the head position adjuster to the fixed position on the upper surface of the head by non-rotating magnetic attachment, it is connected to a stepped portion having an enlarged shape engraved on the upper surface of the head of the putter described later (see FIGS. 20 and 21). In order to be able to be stopped, the mounting member has a shape portion that widens from the front side toward the rear side. (See Figure 1)

  In addition, in order to attach the head position adjuster to the fixed position on the upper surface of the head by non-rotating magnetic attachment, in the modified example of the mounting member, an arbitrary position can be provided at a predetermined rear position from the front end of the lower surface of the mounting member. A locking member (stopper) having a shape is integrated with the mounting member, or a plate-shaped locking member provided with an adhesive (adhesive) agent on one side is fixedly attached to the lower surface of the mounting member or provided detachably, The locking member is interposed between the front surface of the locking member on the back surface of the head or on the back surface of the magnetic seat for magnetically mounting the head position adjuster provided on the top surface of the head (described later). Stopped. (See FIGS. 5, 14, and 15)

  The head position adjuster having the above configuration is preferably symmetrical with respect to the center line direction of the mirror surface so that it can be attached to both right and left handed putters. In order to attach the head position adjuster described in the paragraph (0018) to the non-rotary magnetic attachment at a fixed position on the upper surface of the putter head, the shape of the putter head is set to the upper surface of the head. A step portion where a part of the member is interposed is provided, and at least a portion of the step portion has a shape portion that widens symmetrically across the head axis from the face side toward the head back side, At least a part or the head itself is made of a ferromagnetic material that allows the head position adjuster to be magnetically attached. The step portion is formed by providing a depression or a belt-like protrusion on the upper surface of the head. (See FIG. 1, FIG. 20, FIG. 21)

  In addition, a plate-like magnetic seat with a pressure-sensitive adhesive on one side can be fixedly affixed or attached to the top surface of the head or the back surface of the head back to back. Affixed to. The attachment of the magnetic seat is preferably symmetrical with respect to the head axis. (See FIGS. 16 to 19)

  In the form of the putt training tool in which the head position adjuster is magnetically attached to the head of the putter having the above structure, a sweet spot located on the face of the head is formed on the extension of the center line of the mirror surface of the head position adjuster. It is preferable that the center line of the mirror surface overlaps the head axis and that the front end of the head position adjuster does not protrude forward from the face of the head. And, when using the putting practice tool, the most important mirror inclination angle that allows the player to indirectly see both eyes through the inclined mirror surface is as shown in FIG. 2 and FIG. The position of both eyes (heads) varies depending on the height and preference of the player, and the plurality of tilted line angles toward the center of the mirror surface are slightly different. Therefore, in order to make the vertical width of the mirror surface compact, it is possible to support a plurality of players whose mirror surface inclination angle perpendicular to the plurality of inclination eyes toward the central portion of the mirror surface is 0 degree 30 minutes or more and 5 degrees or less. A predetermined inclination angle is preferable. For example, as shown in FIG. 23, which will be described later, if a plurality of tilted line angles directed to mirror surfaces with different addresses are made the same, the mirror surface perpendicular to the tilted line becomes a mirror surface with a large vertical width, causing a problem of greatly impairing practicality. It will be.

  Therefore, in the present invention, in a state where the average height player sets both eyes right above the ball shown in FIG. 2 which is the most basic at the time of addressing, the eyes are slightly inclined with a slight margin on the inclined mirror surface shown in FIG. Specified tilt angle (the average angle corresponding to the preference of most players is considered to be around 2 degrees and 30 minutes) and the size of the mirror surface, and the difference in the tilt eye angle due to the height difference is not so great Although it seems that it is possible to cope with a constant inclination angle, if the head position is shifted from the upper side of the ball in the left-right direction at the time of addressing, a difference in inclination angle of a certain magnitude occurs. In other words, the tilt angle becomes gentler as the tilted line direction stands upright (the eye is positioned closer to the right side of the ball in a right-handed putter), and the tilted line direction tilts (the eye is positioned closer to the left side of the ball in a right-handed putter). The inclination angle is large.

  Therefore, in order to cope with many players, an angle adjusting means is provided on the lower side (back side) of the reflector shown in FIGS. 8 to 15 described in the paragraphs (0015) to (0017) above, and at least 0 degree 30 minutes or more. The inclination angle of the mirror surface is adjusted within a range of 5 degrees or less. At an inclination angle other than 0 degrees 30 minutes or more and 5 degrees or less, an irregular address posture that deviates too much from the purpose of increasing the practice effect is considered to be impractical.

  As described above, in the putter practice tool of the putter in which the adjuster is attached to the putter that can be attached to the head position adjuster and the adjuster of the present invention, when the address using the put practice tool is adjusted, the putter With both faces aligned at right angles to the line, by placing both eyes on the mirror centerline that is in the same direction as the line, the direction connecting the basic eyes when putting is parallel to the line. It is considered that it is possible to make the direction perpendicular to the longitudinal direction of the film, thereby enhancing the directionality with respect to the line and enhancing the image of placing the ball on the line. Therefore, in order to acquire that both eyes are parallel to the line at the time of addressing, it is practically easy to understand by remembering the orientation of the face, and indirect part of the face including both eyes through the mirror surface. It is possible to easily practice with the face direction always fixed by visual observation, and the effect of improving the patenting technique can be obtained by stabilizing the face direction.

  In addition, when a leveling device is provided that is fixed to the front or rear of the reflecting mirror or magnetized on the mirror surface of the reflecting mirror, the front / rear direction (lie angle) of the putter can be set to a predetermined design direction. By copying both eyes on the center line of the mirror surface, both eyes can be set directly above the most basic line at the time of addressing. When the omnidirectional level is set, the loft angle of the face can be set in a predetermined design direction, and the mirror surface direction of the reflecting mirror can be accurately set in a predetermined direction in all directions.

  When the level is magnetically mounted on the mirror surface, the head position adjuster is simplified, and it becomes easy to use and not use the level during practice. It is possible to immediately sense the sensory difference between the head direction and face direction of the pattern, and practice with the purpose of reducing the difference.

  By providing the angle adjusting means, it becomes easy to utilize the existing putter. That is, when the flatness of the upper surface of the head or the uprightness of the back surface of the head with respect to the loft angle of the putter is different, the mirror surface can be set to a predetermined inclination angle or an inclination angle that suits the player's preference. When the sticking type magnetic seat is provided on the putter, it is possible to attach the putter made of a material other than the ferromagnetic material to the head, and it is possible to deal with many putters having different shapes.

  By providing a locking member on the bottom surface of the head position adjuster mounting member, the head position adjuster attempts to move forward due to the positioning of the head position adjuster on the top surface of the head and the impact when putting. It is intended to stabilize the mounting during use. If the slide type or sticking type locking member is used, the mounting position of the locking member to the head position adjuster can be adjusted, and the depth width of the head upper surface or the depth width of the magnetic seat provided on the head upper surface is different. The putter can be attached to a predetermined position of the putter.

  In the putter provided with a stepped portion having a widened portion on the upper surface of the head position adjuster, and a stepped portion having a widened portion from the face side where the widened side surface is interposed to the rear surface. This makes it possible to install a one-touch magnetic attachment that inserts the head position adjuster from the rear of the head with a wide stepped portion to the inside of the stepped portion, and the head position adjuster tries to move forward due to impact during putting. It is possible to stabilize the mounting during use by receiving the shape with the shape portion that is narrowed toward the front provided in the stepped portion.

  As mentioned above, the head position adjuster and the putter that makes it possible to magnetically attach it are simple and simple to manufacture, so the head position adjuster is stored and carried in a pocket of clothes, etc. It is convenient. In addition, the appearance and performance of the putter head shape are not hindered, and when the head position adjuster is removed, the use of the putter itself of the present invention during the game is not obstructed.

  Hereinafter, among the right-handed and left-handed that can be attached to the head position adjuster of the present invention and the right-handed putter in the embodiment of the present invention, the head position adjuster is used for the putter.
