Description

Detailed Description of the Invention

Technical field to which the invention belongs

  The present invention relates to a putter used for golf putting.

  In general, when putting, first assume the direction and distance of the hit ball, align the face correctly with the ball, take back according to the distance, swing the head down in a pendulum shape, and place the sweet spot on the face There is a theory that hits, but especially beginners have troubles that can not be performed well. As a conventional technique for solving this problem as much as possible, there has been Patent Document 1 and will be described with reference to FIG. 5. A direction indicator 52 so as to be orthogonal to this face above the sweet spot of the face 51 hitting the ball 50. The tip of the direction indicator protrudes to the tip of the face, and the rear end is provided with a telescopic rod 53 that can extend rearward of the face, so that the face can be easily aligned with the target direction of the ball. ing.

Problems to be solved by the invention

  However, in the above conventional technique, the point that the face is easily aligned with the aiming direction of the ball is improved. However, since the direction indicator is disposed above the ball, it is difficult to recognize the position of the ball. The sweet spot is difficult to align with the center of the ball

Means for solving the problem

  In order to solve the above problems, the present invention has the following means: 1. An indicator bar is inserted into a through hole formed in a toe portion of a head perpendicular to the face and separated from the sweet spot by a radius of the ball or more. The ball was slidably attached in the direction of the ball. 2. An indicator rod was detachably attached to a through hole formed in the toe portion of the head that was orthogonal to the face and separated from the sweet spot by more than the radius of the ball. 3. The indicator bar was provided with a plurality of scales at equal intervals, and means for holding the indicator bar at any fixed position within the sliding range. 4). The cross-sectional shape of the indicator rod was formed of either a circle, a tetragon, or a regular hexagon. 5. The heel portion of the head is provided with a detachable balance weight for correcting the misalignment of the sweet spot caused by sliding or attaching the indicator bar.

  In order to eliminate the disadvantage that the sweet spot of the head is difficult to align with the center of the ball and to make it easier to align the face with the target direction of the ball, the toe of the head perpendicular to the face and separated from the sweet spot by more than the radius of the ball The indicator rod is slidably engaged with the through-hole formed in the part. The indicator rod is provided with a plurality of scales at equal intervals, and this indicator rod is placed at any fixed position within the sliding range. Since it can be held by the button, it is possible to select the distance from the face of the pointing bar according to the target distance, and to realize a putter with a simple configuration that can recognize the sense of the amount of back.

1 and 2 are a top view and a side view showing an actual use state of one embodiment of the present invention, wherein 1 is a head body of a putter made of stainless steel, a sole surface 8 at the lower end, A face 17 is formed on one side, and a sweet spot 7 is located at a substantially central portion of the face, 6 is a toe portion 18 that is orthogonal to the face and is separated from the sweet spot by a radius of the ball or more. The formed through-hole is made of an aluminum alloy wire or polycarbonate resin, and is fitted with an indicator rod 15 having a plurality of scales at equal intervals in the radial direction (sliding in the direction of arrow P in FIG. 1). 20 is a screw hole formed in the protruding portion 2 provided to extend to the toe portion 18, 21 is a pore that is drilled at the tip of the screw hole and intersects the through hole 6, and 5 is a thin hole Slider with jaw and convex part slipped into the hole, 3 Is a set screw that is screwed into the screw holes 20, 4 is biased compression spring between the jaws of the set screw 3 and the slider 5.
Reference numeral 10 denotes a balance weight made of a metal having a high specific gravity (for example, lead) screwed into a screw hole 9 formed in the heel portion and having a screw shape on the outer peripheral portion, and 13 is a center formed just above the sweet spot. A display line, 14 is a ball, and 12 is a putter shaft fixed to the hosel part.

FIG. 3A shows a first embodiment of the indicator bar. The indicator bar 15 is formed in the through hole 6 with a circular cross section and a narrow groove 16 in the radial direction provided at equal intervals in the longitudinal direction. When the slider 5 slides, the convex portion of the slider 5 pressed by the compression spring 4 is fitted into the groove 16, and the indicator bar 15 is held at a predetermined position in the through hole 6.
FIG. 3B shows a second embodiment of the indicating rod, which has the same function as the above by forming a graduation with an angular section in the circumferential direction at equal intervals in the circumferential direction, and has the same function as above, but recognizes the direction more. There are easy advantages.
FIG. 3C shows a third embodiment of the indicating rod, which is hexagonal in cross section and has narrow grooves 16 in the circumferential direction at equal intervals to form a scale and performs the same function as above, but when used under hot weather. , There is an advantage that the reflection of light is small and the direction can be recognized more easily.

  Next, the case where the putter having the above-described configuration is actually practiced will be described. After assuming the hitting ball distance and the flying ball line, first, the direction indicator rod 15 is inserted into the through hole 6 according to the assumed distance. The distance from the end of the head (L dimension in FIG. 1) is set by sliding the inside of the head. In this case, a scale provided at equal intervals on the indicator bar can be used. For example, one scale is 1 m. If you decide to aim for a distance of 6m, set the 6 scales on the L dimension in Fig. 1. Next, to set the face to the assumed flying ball line, move the indicator rod from the flying ball line. The face is automatically set at a right angle to the flying line when the sweet spot 7 is aligned with the center of the ball after aligning the center display line 13 with the center of the ball 14 by aligning the H dimension in FIG. Take back accordingly and swing the head in a pendulum shape And to hit the sweet spot of the filter paper face to the ball the ball is holed out.

The invention's effect

  As described above, in the putter of the present invention, the indicator rod is slidably engaged with the through hole formed in the toe portion of the head which is orthogonal to the face and is more than the radius of the ball from the sweet spot. This makes it easy to align the face with the ball correctly, and the indicator bar is provided with a plurality of scales at equal intervals, and this indicator bar can be held at any fixed position within the sliding range. Since the distance from the head end can be selected and the sense of the takeback amount can be recognized, a configuration in which a putter with a high cup-in rate can be achieved with a simple configuration has been realized.

  It is a top view which shows the actual use condition of one Example of this invention.   It is a side view which shows the actual use condition of one Example of this invention.   FIG. 3A shows a first embodiment of the indicator bar. FIG. 3B shows a second embodiment of the indicator bar. FIG. 3C shows a third embodiment of the indicator bar.   It is a top view which shows a prior art.
