For this purpose, transparent members 4 and 14 with lengths extending downward from the upper surface of the head 2 are disposed in the head 2, and lines 6 and 7 and lines 16 and 17 extending in a direction at a right angle to a face 2A of the head 2 are displayed as the two marks on the upper and lower surfaces 4A, 4B, and 14A, 14B of the transparent members 4 and 14.

Description

  The present invention relates to a putter club used in golf, and more particularly to a head of the putter club.

  In order to swing the putter club correctly in order to strike the golf ball in the correct direction with the putter club on the golf course green, when the golfer grasps the putter club and takes the posture of the address, the golfer's It is important that the position of the eye (in other words, the position of the golfer's head) is in the correct position above the head that should be. Patent Document 1 and Patent Document 2 listed below show golf putter clubs capable of confirming whether or not a golfer's eyes are in such an accurate position.

  In the golf putter club disclosed in Patent Document 1, a groove is formed on the upper surface of the head in parallel with the face of the head, and first marks are displayed on both sides of the groove, and further, at the bottom of the groove. A second mark is displayed. When the position of the golfer's eyes is at an accurate position above the head, which is supposed to be, these marks coincide with each other. When the golfer's eyes are at an incorrect position, these marks do not coincide with each other and shift from each other.

  That is, in Patent Document 1, two marks are displayed on the head with a difference in height between the upper and lower sides, and the golfer visually recognizes these marks so that the position of the golfer's eyes should be above the head. Whether or not it is in the correct position can be determined by matching or mismatching of the two marks.

  In the golf putter club shown in Patent Document 2, a circular non-through hole extending downward from the upper surface of the head is formed in the head. When the golfer visually recognizes the non-through hole, When the eye position is at an accurate position above the head, the circular upper end portion and the circular bottom end portion of the non-through hole overlap each other. It is possible to determine whether or not it is at an accurate position above the head that should be.

  For this reason, even in the golf putter club shown in Patent Document 2, two marks (the above-described circular top end and circular bottom end) are displayed on the head with a difference in height between the top and bottom. It is the same configuration as that of the two marks, and when the golfer visually recognizes these marks, whether or not the position of the eye of the golfer is at an accurate position above the head which should be originally coincides with the two marks, Judgment can be made based on inconsistencies.

JP 2006-247320 A Japanese Utility Model Publication No. 7-27633

  In the golf putter clubs shown in Patent Document 1 and Patent Document 2, grooves and non-through holes are formed in the head in order to display two marks on the head with a difference in height between the top and bottom. Therefore, there is a possibility that dust such as turf leaves and bunker sand existing in the golf course may enter into the grooves and the non-through holes. For this reason, when such dust has entered the inside of the groove or the non-through hole, it is determined whether or not the position of the golfer's eyes is at an accurate position above the head that should be. The problem arises that it must be done after removing.

  It is an object of the present invention to enable golf players to determine whether or not the position of a golfer's eyes is at an accurate position above the head that should be originally formed without forming a groove or a non-through hole in the head. There is a putter club.

  In the golf putter club according to the present invention, two marks are displayed on the head with a difference in height between the top and bottom, and the golfer visually recognizes these marks so that the position of the eye of the golfer should be originally located. In the golf putter club for judging whether or not the two marks are in the correct position by matching or mismatching of the two marks, a transparent member having a length extending downward from the upper surface of the head inside the head And lines extending in a direction perpendicular to the face of the head are displayed on the upper and lower surfaces of the transparent member, and these lines are the two marks. To do.

  In the golf putter club according to the present invention, a transparent member having a length extending downward from the upper surface of the head is disposed inside the head, and the upper and lower surfaces of the transparent member are perpendicular to the face of the head. Since the lines extending in the direction are displayed and these lines are the two marks, no groove or non-through hole is formed in the head. In other words, even if a through hole or a non-through hole extending downward from the upper surface of the head is formed in the head in order to arrange a transparent member having a length extending downward from the upper surface of the head, Since the through hole or the non-through hole is closed by the transparent member, no groove or non-through hole is formed in the head.

  For this reason, according to the present invention, there is no problem that dust such as turf leaves or bunker sand existing in the golf course enters the groove or the non-through hole, and therefore it is unnecessary to remove these dust. become.

  In addition, the golfer visually recognizes two lines displayed as two marks with a difference in height between the head and the head from above the head, so that the position of the golfer's eyes should be above the head. Whether or not it is in the correct position can be determined by matching or mismatching between the line displayed on the upper surface of the transparent member and the line displayed on the lower surface of the transparent member and can be recognized through the transparent member. Therefore, the golfer can correctly hit the golf ball with the golf putter club after setting the eye position to the correct position above the head which should be originally.

  In the present invention, the number of the transparent members described above may be one or plural.

  One example of the case where the number of transparent members is plural is that the above-mentioned transparent member is the first transparent member, and a second transparent member having a length extending downward from the upper surface of the head is disposed inside the head. A line extending in a direction perpendicular to the head face is displayed on each of the upper and lower surfaces of the second transparent member, and the first transparent member and the second transparent member are juxtaposed in a direction perpendicular to the head face. In addition, the line displayed on the upper surface of the other transparent member is disposed on the extension of the line displayed on the upper surface of one of the first transparent member and the second transparent member. That is.

  According to this, the golfer can recognize each line displayed on the upper surface of each of the first transparent member and the second transparent member as one long line, and this one long line. Since the golf ball extends in a direction perpendicular to the head face, the golfer plays golf in a direction perpendicular to the head face, which is the direction in which the golf ball is correctly launched, using this single long line as a mark. You can hit the ball accurately.

  Another example of the case where the number of transparent members is plural is that the above-mentioned transparent member is the first transparent member, and the second transparent member has a length extending downward from the upper surface of the head inside the head. And a line extending in a direction parallel to the face of the head is displayed on each of the upper and lower surfaces of the second transparent member.

  According to this, whether or not the position of the golfer's eyes is in an accurate position above the head that should be originally in the front-rear direction of the golfer due to the match or mismatch of the lines displayed on the upper and lower surfaces of the first transparent member. The position of the golfer's eyes is the exact position above the head that should be in the horizontal direction of the golfer due to the match / mismatch of the lines displayed on the upper and lower surfaces of the second transparent member. It will be possible to determine whether or not

  In addition, as described above, lines extending in a direction perpendicular to the face of the head are displayed on the upper and lower surfaces of the first transparent member and the second transparent member disposed inside the head, respectively. The member and the second transparent member are arranged side by side in a direction perpendicular to the face of the head, and on the extension of the line displayed on the upper surface of one transparent member of the first transparent member and the second transparent member. When the lines displayed on the upper surface of the other transparent member are arranged, the upper and lower surfaces of one transparent member of the first transparent member and the second transparent member should be parallel to the face of the head. You may display the line extended in the direction made.

  According to this, a line extending in a direction perpendicular to the face of the head and a line extending in a direction parallel to the face of the head are displayed on each of the upper and lower surfaces of the first transparent member and the second transparent member. With the single transparent member, it is possible to determine whether or not the position of the golfer's eyes is in an accurate position above the head that should be originally in both the front-rear direction and the left-right direction of the golfer. In addition, the golfer recognizes one long line by the lines extending in the direction perpendicular to the head face on the upper surfaces of the first transparent member and the second transparent member. Using this single long line as a mark, hit the golf ball accurately in the direction perpendicular to the head face, which is the direction to correctly hit the golf ball. Also to be able to bet.

  Further, in the present invention, when the number of transparent members arranged inside the head is one, the upper and lower surfaces of the transparent member are arranged in a direction perpendicular to the head face as described above. In addition to displaying an extended line, a line extending in a direction parallel to the face of the head may be displayed. That is, two lines may be displayed in a cross shape on each of the upper and lower surfaces of one transparent member.

  According to this, the number of transparent members arranged inside the head can be limited to one, and the position of the golfer's eyes in both the front-rear direction and the left-right direction of the golfer can be achieved by the single transparent member. It is possible to determine whether or not the head is at an accurate position above the head that should be.

  In the present invention described above, it is preferable to provide a level for confirming the level of the head in the direction perpendicular to the aforementioned line on the upper surface of the head.

  According to this, when determining whether or not the position of the golfer's eyes is in the correct position above the head, which is supposed to be in the front-rear direction and the left-right direction of the golfer, the level is perpendicular to the line. Since the level of the head in the formed direction can be confirmed, the above determination can be made accurately.

  As for the above-mentioned line, there are two types of golf putter clubs: a line extending in a direction perpendicular to the face of the head and a line extending in a direction parallel to the face of the head. There may be two provided for each of these lines, or one that can be used to confirm the level of the head in common for both of these lines.

  In addition, as described above, disposing the transparent member having a length extending downward from the upper surface of the head inside the head means that the transparent member is disposed from the upper surface to the lower surface in order to dispose the transparent member inside the head. A through-hole reaching up to the top may be formed in the head, and a transparent member having upper and lower surfaces corresponding to the upper and lower surfaces of the head may be inserted into the through-hole, or the transparent member In the head, a non-through hole that extends downward from the upper surface of the head but does not reach the lower surface of the head is formed in the head. The non-through hole corresponds to the depth of the non-through hole. You may carry out by inserting the transparent member which has the up-and-down length to do.

  According to the present invention, it is possible to determine whether or not the position of the golfer's eyes is an accurate position above the head that should be originally formed, without forming a groove or a non-through hole in the head. Thus, it is possible to obtain an effect that it is not necessary to remove dust that enters the groove or the non-through hole.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on drawing. FIG. 1 shows a front view of a head 2 of a golf putter club 1 according to the present embodiment. Near one end portion of the upper surface of the head 2, a lower end portion of the shaft 10 is coupled, and a grip gripped by the golfer is attached to an upper end portion (not shown) of the shaft 10.

  FIG. 2 shows a plan view of the head 2, and FIG. 3 shows a perspective view of the head 2. As shown in FIG. 2, the head 2 has a bulging portion 2 </ b> B that bulges substantially backward in a substantially trapezoidal shape from the face 2 </ b> A serving as a surface for hitting the golf ball 11 in the head 2. It has become. The head 2 whose upper and lower surfaces are parallel includes a head body 3 and a first transparent member 4 and a second transparent member 14 which are solid cylindrical members. That is, as shown in FIG. 3, the head 2 extends downward from the upper surface of the head 2 and reaches the lower surface of the head 2. Since the first and second transparent members 4 and 14 that are cylindrical solid members having the same diameter are inserted into and fixed to the through holes 5, the head 2 has two through holes. The head main body 3 in which the holes 5 are formed, the first transparent member 4 and the second transparent member 14 are included.

  Further, as shown in FIG. 4 showing an exploded perspective view of the head 2, the head body 3 excluding the first and second transparent members 4, 14 of the head 2 is a thin sub-plate. The portion 3A includes an upper main portion 3B having a larger vertical dimension than the sub portion 3A and having a lower surface bonded to the upper surface of the sub portion 3A by bonding or the like. Therefore, the head body 3 is formed by vertically stacking the sub part 3A and the main part 3B. The sub-portion 3A is made of aluminum, aluminum alloy, steel, or metal such as stainless steel. On the other hand, the main portion 3B is made of wood, and the material of the main portion 3B is e.g. Hard wood such as firewood. Thereby, in the face 2A of the head 2, the sweet spot which is a place where the golf ball 11 is to be hit is formed of hard wood, and therefore, when the golf ball 11 is hit, the sweet spot is good. A hit feeling can be obtained.

  Further, since the head main body 3 is formed by laminating different materials of metal and wood in two layers, it is possible to obtain a good feel when the golf ball 11 is hit as described above with wood. However, a good head weight when the putter club 1 is swung can be obtained.

  As shown in FIG. 4, two circular holes 5 </ b> A and 5 </ b> B penetrating vertically are formed in the sub part 3 </ b> A and the main part 3 </ b> B constituting the head body 3 according to the present embodiment. When the sub-portion 3A and the main portion 3B are bonded together by bonding or the like, the above-described through-hole 5 to be formed by these holes 5A and 5B is made of, for example, a transparent synthetic resin material such as acrylic or The first and second transparent members 4, 14 made of hard glass or the like are inserted, and the transparent member 4, by the adhesive applied to the inner peripheral surface of the through hole 5 or the outer peripheral surface of the transparent members 4, 14. 14 is fixed to the through hole 5.

  The vertical length of the transparent members 4, 14, that is, the height dimension of the transparent members 4, 14 is the same as the vertical dimension of the head body 3. For this reason, when the transparent members 4 and 14 are inserted and fixed in the through-hole 5, the upper surfaces 4A and 14A of the transparent members 4 and 14 coincide with the upper surface of the head body 3, and the lower surfaces of the transparent members 4 and 14 4B and 14B coincide with the lower surface (sole) of the head body 3. Therefore, the height positions of the upper and lower surfaces 4A, 14A, 4B, and 14B of the transparent members 4 and 14 are positions corresponding to the upper and lower surfaces of the head 2. For this reason, the transparent members 4 and 14 have a length extending downward from the upper surface of the head 2.

  On the circular upper surfaces 4A and 14A of the first and second transparent members 4 and 14, lines 6 and 16 extending in the diameter direction of the upper surfaces 4A and 14A through the central portions of the upper surfaces 4A and 14A are displayed. In addition, the circular bottom surfaces 4B and 14B of the first and second transparent members 4 and 14 also pass through the central portions of the bottom surfaces 4B and 14B, and the line 7 extends in the diameter direction of the bottom surfaces 4B and 14B. , 17 are displayed, and the extending directions of these lines 6 and 7 and lines 16 and 17 are the same. These lines 6, 16, 7, and 17 are displayed by directly drawing lines with paint on the upper and lower surfaces 4A, 14A, 4B, and 14B that are flat surfaces of the first and second transparent members 4 and 14. Alternatively, the display may be performed by embedding paint in narrow grooves formed on the upper and lower surfaces 4A, 14A, 4B, and 14B.

  Further, the above-described paints of the lines 6, 16, 7, and 17 are colors that can be clearly distinguished from the green color of the golf course, that is, black, white, red, or the like. Further, when inserting and fixing the first and second transparent members 4 and 14 in the through hole 5, the direction of the lines 6, 16, 7, and 17 is set to a direction perpendicular to the face 2A of the head 2, and this insertion, Perform fixing work.

  Since the lines 6, 16, 7, and 17 that are oriented in this way are displayed on the upper and lower surfaces 4 </ b> A, 14 </ b> A, 4 </ b> B, and 14 </ b> B of the transparent members 4 and 14, the head 2 according to the present embodiment has With the lines 6 and 7 and the lines 16 and 17 displayed with a difference in height between the upper and lower sides, two marks are provided with a difference in height between the respective transparent members 4 and 14. . The lower lines 7 and 17 can be seen from above the head 2 through the transparent members 4 and 14.

  Further, in the present embodiment, the center portion of the two circular through-holes 5 is the aforementioned sweet spot 2C shown in FIG. 2 in the face 2A (the sweet spot 2C in FIG. 2 is shown in a dot state). However, it has an area.) And is on a line extending in a direction perpendicular to the face 2A. For this reason, the first and second transparent members 4 and 14 are arranged side by side in a direction perpendicular to the face 2A, thereby extending the line 6 displayed on the upper surface 4A of the first transparent member 4. The line 16 displayed on the upper surface 14A of the second transparent member 14 is arranged on the lower surface 14B of the second transparent member 14 on the extension of the line 7 displayed on the lower surface 4B of the first transparent member 4. The line 17 is arranged.

  When the golfer hits the golf ball 11 with the putter club 1 on the golf course green, as shown in FIG. 1, the golfer's eyes 12 holding the grip and taking the posture of the address are It is in the upper position. FIGS. 5A, 5B, and 5C show two marks displayed as two marks on the upper and lower surfaces 4A, 4B, 14A, and 14B of the transparent members 4 and 14 depending on the position of the eye 12, respectively. The lines 6 and 7 and the lines 16 and 17 have different appearances.

  FIG. 5A shows a case where two lines 6 and 7 and lines 16 and 17 are seen overlapping by the golfer. As described above, these lines 6, 7, 16, and 17 The extending directions are the same, and the lines 6, 7, 16, and 17 coincide with a line that passes through the sweet spot 2C and extends in a direction perpendicular to the face 2A. The position is in the exact position above the head 2 that should be.

  On the other hand, in FIG. 5B, the lines 6 and 16 displayed on the upper surfaces 4A and 14A of the transparent members 4 and 14 are displayed on the lower surfaces 4B and 14B of the transparent members 4 and 14 by the golfer. This is when the lines 7 and 17 are viewed as being shifted from the side opposite to the golfer's body side, in other words, to the front side with respect to the golfer. The position is shifted to the opposite side of the golfer's body with respect to the exact position above.

  5C shows a line 7 in which the lines 6 and 16 displayed on the upper surfaces 4A and 14A of the transparent members 4 and 14 are displayed on the lower surfaces 4B and 14B of the transparent members 4 and 14 by the golfer. , 17, 17, 17 in other words, when viewed from the back of the golfer, and in this case, the position of the eye 12 is an accurate position above the head 2 that should be originally located. On the other hand, it is in a position shifted to the golfer's body side.

  For this reason, the golfer determines whether the position of the eye 12 is originally determined by whether or not the two lines 6 and 7 and the lines 16 and 17 overlap. In other words, the line 6 and 7 and the lines 16 and 17 match or do not match. It can be determined whether or not it is at an accurate position above the head 2, and after moving the position of the eye 12 to a position where the lines 6 and 7 and the lines 16 and 17 coincide, in other words, the line After the head position is moved to the position where the lines 6 and 7 and the lines 16 and 17 coincide with each other, the golf ball 11 is hit to correctly swing the putter club 1.

  In this embodiment, the lines 6 and 7 and the lines 16 and 17 are two marks for determining whether or not the position of the eye 12 is at an accurate position above the head 2 that should be originally located. Is not displayed on the head 2 by forming non-grooves or through holes in the head 2, and these lines 6, 7, 16, and 17 are located inside the head 2 from the top surface of the head 2 downward. Displayed on the upper and lower surfaces 4A, 4B, 14A, and 14B of the transparent members 4 and 14 that are arranged to extend, and the height positions of these upper and lower surfaces 4A, 4B, 14A, and 14B are above the head 2. In other words, since the two through holes 5 formed in the head 2 are blocked by the transparent members 4 and 14, the head 2 has a groove. No non-through hole is formed.

  For this reason, according to the putter club 1 according to the present embodiment, there is no problem that dust such as turf leaves or bunker sand existing in the golf course enters the groove or the non-through hole, and the dust is removed. Thus, the golfer can concentrate on swinging the putter club 1.

  Further, in the putter club 1 according to the present embodiment, the head 2 is provided with two transparent members 4 and 14, and the transparent member 4 is displayed on the upper surface 4 </ b> A of one transparent member 4. The line 16 displayed on the upper surface of the other transparent member 14 is arranged on the extension of the line 6, and the two transparent members 4, 14 are in a direction perpendicular to the face 2 A of the head 2. Since they are arranged side by side, the golfer can recognize that the lines 6 and 7 displayed on the upper surfaces 4A and 14A of the two transparent members 4 and 14 form one long line. Since this one long line extends in a direction perpendicular to the face 2A of the head 2, the golfer uses this one long line as a mark to correctly strike the golf ball 11. The golf ball 11 can be accurately hit in a direction perpendicular to the face 2A of the head 2 formed.

  FIG. 6 shows an embodiment in which the head main body 3 is formed by stacking different materials of metal and wood in three upper and lower layers. That is, the second sub-part 3C made of metal such as aluminum, aluminum alloy, steel or stainless steel is provided on the upper side of the main part 3B arranged on the sub-part 3A. Thereby, the head body 3 has a three-layer structure.

  Even in the head 2 of this embodiment, the golf ball 11 is hit by the wooden main portion 3B which can obtain a good hit feeling. Since the metal sub-parts 3A and 3B are arranged above and below the wooden main part 3B, a better head weight when the putter club 1 is swung can be obtained, and the wooden main part 3B can be It can also be protected by the metal sub-parts 3A and 3B.

  In the embodiment of FIG. 7, the level 20 is arranged on the upper surface of the head 2. This level 20 is the level of the head 2 in the direction perpendicular to the lines 6, 7, 16, 17 displayed on the transparent members 4, 14, in other words, in the direction parallel to the face 2 A of the head 2. It is for confirming. Note that the level 20 used in the present embodiment has a liquid tube 23 and a bubble 24 sealed inside a transparent tube 22 such as a glass tube with a mark line 22A. Other structures may also be used.

  According to this embodiment, the level 20 can confirm whether or not the posture of the head 2 is accurately horizontal in the direction perpendicular to the lines 6, 7, 16, and 17. When the level 20 confirms that the level has been accurately changed, the lines 6 and 7 and the lines 16 and 17 of the transparent members 4 and 14 are determined to match or not match as described above. This judgment can be made accurate.

  Also in the embodiment of FIG. 8, two transparent members 4, 24 are arranged inside the head 2, and one of the transparent members 4, 24 is the first transparent member shown in FIG. 2 or the like. 4 and the other transparent member is the second transparent member 24 in this embodiment. The second transparent member 24 has upper and lower surfaces 24A and 24B that are at height positions corresponding to the upper and lower surfaces of the head 2, and the upper and lower surfaces 24A and 24B have circular upper and lower surfaces 24A. , 24B extending in the diameter direction of the upper and lower surfaces 24A, 24B are displayed, and these lines 26, 27 extend in a direction parallel to the face 2A of the head 2.

  According to this embodiment, due to the coincidence or mismatch of the lines 6, 7 displayed on the upper and lower surfaces 4 </ b> A, 4 </ b> B of the first transparent member 4, the golfer's eyes 12 can It is possible to determine whether or not the upper position is accurate, and the golfer's eyes 12 are moved to the left and right sides of the golfer by matching or mismatching of the lines 26 and 27 displayed on the upper and lower surfaces 24A and 24B of the second transparent member 24. It can be determined whether or not the direction is an accurate position above the head 2 that should be. For this reason, it becomes possible to more accurately determine whether or not the golfer's eyes 12 are at an accurate position above the head 2 that should be originally located.

  FIG. 9 shows a case where the golfer's eyes 12 are displaced to the left side of the golfer, in other words, to the face 2A side of the head 2 with respect to the exact position above the head 2 which should be originally, In this golf player, the line 27 appears to be shifted to the right with respect to the line 26.

  In this embodiment, as shown in FIG. 8, two levels 20 and 21 are arranged on the upper surface of the head 2. Among these levels 20 and 21, the level 20 is for confirming the level of the head 2 in the direction perpendicular to the lines 6 and 7 displayed on the first transparent member 4. The vessel 21 is for confirming the level of the head 2 in the direction perpendicular to the lines 26 and 27 displayed on the second transparent member 24. For this reason, the lines 6 and 7 and the lines 26 and 27 of the first and second transparent members 4 and 24 allow the golfer's eyes 12 to be positioned above the head 2 that should be originally in both the front-rear direction and the left-right direction of the golfer. When determining whether or not it is in the correct position, the posture of the head 2 is accurately leveled in both the direction perpendicular to the lines 6 and 7 and the direction perpendicular to the lines 26 and 27. It will be possible to confirm whether or not.
