Description

  The present invention relates to a golf putter training machine that can accurately grasp the trajectory of a golf ball launched by the putter and trains an accurate putting technique in the golf putter practice.

  Conventionally, as a putter training machine devised as this type of putter training machine, there is described a putter training machine (Japanese Patent Laid-Open No. 8-89613) that can detect the level of an installation place by a level. A training machine that accurately moves a golf ball straight is well known.

  In golf putter practice, it is important that the golfer's senses match the actual golf ball trajectory, and many professional golfers and amateur golfers agree on the straight line (a straight rolling line). Practice to let you. In fact, in the course green, this feeling is combined with a sense of distance and placed on a line (a temporary trajectory that rolls into a cup that takes into account the natural forces such as tilt and grass). However, it is difficult to find a perfect straight line even on the practice green of the golf course. Even in the same place and the same line, in the morning and noon, it is often natural effects such as grass growth, and the shoe mark of the practitioner. The line and the sense of distance change under the influence of.

  In addition, the practitioner's feelings are usually found and practiced, but the practitioner's feelings differ depending on the condition and condition of the day. When a golf ball rolls with a hook rotation (a ball that rolls to the left) with respect to a line that rolls as it is applied, the golf balls cancel each other's forces, and the golf ball may roll straight. For this reason, in order for the practitioner to practice as if it were a straight line, the golf ball that should have been rolled straight on the course green in the course green turns the hook and moves to the left. In addition, the practitioner feels a hook line (a line that rolls like a curve on the left), so that the senses go wrong.

  In course green, the speed of the green (the distance that the ball rolls) changes depending on the length of the lawn, etc., because it changes the difficulty of the entire course of the day. Some golf courses display the distance the golf ball rolls with a steep meter (green speedometer) as the speed of the green of the day by feet. In addition, the course green has an inclination in most cases, and the putting technique is required in a situation where the balance changes because the toes are lowered, the toes are raised, the forefoot is raised, and the forefoot is lowered.

  In addition, golf putter training machines constructed with artificial grass as in the past do not have a perfect straight line because they are affected by the artificial grass and subtle inclinations of equipment and floors. . Also, it is important for the practitioner to recognize how the golf ball is hit by the putter and then hit with the target that hits the ball. Straight rotation (ball that rolls straight) Slice rotation (ball that rolls to the right) ) Some practitioners, such as hook rotation (balls that roll to the left), also have golfers who practice according to the situation. However, due to natural influences such as grass growth, practitioners' shoe marks, artificial grass turf and eyelids, subtle tilting of equipment and floors, etc., there is an uncertain factor, so the trajectory due to the rotation of the golf ball is pure. I can't judge.

  From these facts, a golf putter training machine that can form a complete straight line that is not affected by uncertainties and that can determine the trajectory of the golf ball purely. It is another object of the present invention to provide a golf putter training machine that can reproduce the speed of green and can reproduce an unbalanced situation when putting.

  In order to solve this problem, the means taken by the present invention includes a golf ball traveling path member on which the golf ball of claim 1 is placed, a support section on which the traveling path member is mounted and held, and a practice table on which a practitioner performs a trial. A golf putter training machine having a weight portion for maintaining the horizontal direction of the traveling road in the golf ball traveling path, and a swinging mounting point with the golf ball traveling path longitudinal center axis as a fulcrum. A golf putter training machine that is mounted and held on a support member provided with a holding part and is configured to keep the golf ball travel path width direction horizontal by gravity.

  In addition, the swingable golf ball travel path width direction is kept horizontal by gravity, and a travel path fixing portion for fixing the state is provided, and the golf ball travel path width direction is fixed and held horizontally. A golf putter practice machine characterized by being configured to maintain a horizontal position.

  Furthermore, the golf putter practice machine includes a golf ball return path that is returned to a golf ball take-out port near the practitioner on a support member provided with a supporting point holding portion for mounting the longitudinal center axis of the golf ball traveling path. A golf putter training machine characterized by

  Further, the golf ball travel path width direction is configured to have a golf cup diameter of about 4.25 inches or less, and a complete straight line can be configured by adhering a felt-based nonwoven fabric to the surface of the golf ball travel path. Golf putter training machine.

  Also, the golf ball travel path is provided with a height adjustment function for each foot (green speed) for providing an inclination in the longitudinal direction of the support member of the support member to be mounted, and the speed of the green can be reproduced by the inclination resistance. Golf putter practice machine.

  In addition, the practice platform on which the practitioner performs the trial is generally box-shaped, and includes means that can be tilted back and forth and left and right by sandwiching a golf ball or height adjustment hardware between the practice platform lid and the practice platform support Golf putter practice machine.

  In the structure of the present invention, first, the practitioner installs the training machine main body and the height practice table on the floor or the ground. After the golf ball traveling path provided with the weight portion is stabilized, the golf ball traveling path is fixed by the fixing portion. As a result, the golf ball travel path width direction is kept horizontal and maintained by gravity. It is possible to provide a complete straight line that is not affected by uncertain factors such as natural effects such as grass growth, practitioner's shoe prints, artificial grass turf and wings, and subtle inclinations of equipment and floors. In addition, a complete straight line can be provided even when grounded to a place with a certain degree of inclination or unevenness. A center train is provided on the center of the road, and the practitioner performs putting practice based on this. When hit by straight rotation, the golf ball rolls straight on the center line. Moreover, when it is launched by slicing rotation, it rolls slightly to the left from the center line and rolls back to the center line as if a curve was applied. When it is launched by hook rotation, it rolls slightly to the right from the center line and rolls back to the center line as if it was curved. A ball with poor directionality falls from the golf ball travel path to the golf ball return travel path and returns to the golf ball outlet near the practitioner.

  This makes it possible to always provide a stable and complete straight line without relying on the practitioner's senses and without having to search for a straight line. The practice you are doing can be done stably. In addition, when a sensation occurs, a stable straight line is always constructed, so that the same sensation can be regained in the same practice.

  In addition, the height adjustment function in the vertical direction of the support member can be adjusted, and the speed of the green can be reproduced by the inclination resistance, so that it is possible to practice striking strength that matches the length of the green turf (green speed).

  Furthermore, since it is in the shape of an elongated box, it can be installed on the wall and does not require a wide installation surface. This makes it possible to practice putting the head on the wall so that the head does not move when putting.

  In addition, since the felt-based non-woven fabric close to the billiards is provided on the surface, it is not affected by the lawn, so the golf ball rolls only by the rotation applied purely by the impact of the putter. It is possible to grasp whether the golf ball trajectory is a straight rotation, a slice rotation, or a hook rotation, and it is possible to practice separately. The golf ball trajectory that the practitioner launches can be grasped, and the golf ball trajectory can be practiced so that the practitioner's sense matches the actual golf ball trajectory. I can judge.

  In addition, since the practice platform can tilt forward, backward, left and right, putting exercises in a poorly balanced state such as toe-down, toe-up, forefoot-up and forefoot-down can be performed.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a schematic configuration of the present invention, and a practitioner 1 is also illustrated. The main body of the training machine has a generally elongated box shape as a whole. The rail-shaped golf ball travel path member 2 provided with a weight portion is swingably mounted and supported by a support portion 4 provided with a golf ball return path by a longitudinally central shaft portion 3. Further, the grooves 5 at both ends of the traveling path are provided larger than the golf ball, and fall on the golf ball return path when the golf ball comes off the traveling path. Further, the golf ball traveling path member 1 can be fixed so as not to move by the fixing portion 6 while keeping the level by the weight portion provided at the bottom of the traveling path. The golf ball 7 that has come off at both ends of the travel path is returned to the golf ball outlet 8 by the golf ball return path. Since the installation surface is higher than the floor due to the structure, it is possible to practice at the same height as the road by the practice table 9 that can be tilted back and forth and left and right.

  2 is a side cross-sectional view taken along line ab of FIG. The travel path member 2 can be kept horizontal by gravity by being supported by the support member 4 by the travel path member central portion 10 and by providing the weight portion 11 at the bottom. The width of the travel path member 2 is optimally about the golf cup size to the golf ball diameter in order to keep the horizontal in the width direction by the weight portion. This should be set according to the skill of the practitioner. The golf ball return path 12 provided on the support portion 4 provided with the golf ball return path is inclined so that the golf ball rolls at the golf ball take-out port 8.

  FIG. 3 is a side view of the travel path member 2. The material for forming the travel path member is preferably a light material with little distortion and an alloy such as aluminum is optimal. If a three-dimensional measuring instrument that can measure three distances of one side, depth, and height of the object to be measured is used as a device for measuring this, a precise travel path member can be provided. In addition, the weight portion 11 should be accurately provided at the center of the traveling path. Further, when the travel path member is formed of synthetic resin or the like, a flat travel path member can be formed by bonding a glass material with little distortion or warping to the travel path surface. Woven felt used for billiard rafts on the surface of a flat running road member, woven felt with a thickness of 0.85mm to 0.95mm with 70% wool and 30% nylon is optimal. A center line is provided on the center of a felt-based non-woven fabric similar to a silky non-woven fabric, and the traveling path member central shaft portion 3A is supported by the support member 4, and the weight section 11 keeps the traveling path member horizontal.

  FIG. 4 is a front view in which a travel path member is removed from a support portion provided with a golf ball return path. The material for forming the support portion provided with this golf ball return path may be an alloy such as aluminum, but is optimally formed of a synthetic resin or the like. Further, the golf ball return path 12 is inclined so that the golf ball rolls at the golf ball take-out port 8, the travel path member is held by the shaft holding part 3 </ b> B, and the weight part is kept horizontal by the fixing part 6. Later, the travel path member can be fixed so as not to move.

  FIG. 5 is a cross-sectional view of the fixing portion 6. When fixing, it is important that the traveling shaft member central shaft portion 3A is kept horizontal and can be fixed securely, and a screw type is optimal. The support portion 4 is provided with a female screw portion 14 made of metal, and by rotating the fixing portion 6, the bolt portion 15 applies pressure to the rubber portion 13 so that the travel shaft member central shaft portion does not move. Can be fixed.

  FIG. 6 is a side view showing a schematic configuration of the present invention. The ground is also shown. The practice table front leg 16 is optimally made of rubber that does not slip when installed on the floor or ground. In addition, Table 1 shows stump meters (putting) in order to reproduce the speed of the green by the inclination resistance of the training machine by providing a function 17 that can adjust the height behind the supporting member that constitutes the running path member. This is a table in which the distance by which the golf ball is actually rolled in green by a green speedometer is divided into feet and the friction coefficient is determined by distance. The actual golf ball rolling was equivalent to 7 feet 2100 mm with a friction coefficient of 0.081136297 and the same travel distance of 2100 mm with the felt-based nonwoven fabric of the present invention adhered, and an equivalent golf ball rolling at an inclination angle of 3.6 degrees. In order to provide this inclination angle, the rolling resistance equivalent to the 7-foot friction coefficient of 0.081136297 can be reproduced by increasing the depth of the training machine having a total length of 2400 mm by 150.96 mm. Similarly, it is optimal to determine the height based on the coefficient of friction and the implementation, and to provide a height adjustment function of about 5 steps for each foot. The height can be changed simply, and a simple structure is good considering the cost. It is optimal to insert a pin into the hole provided for each foot and change the height or to change the height for each foot by adjusting the angle. In addition, since the rolling speed of the ball can be adjusted by changing the thickness and composition of the felt-based nonwoven fabric, the height and angle described above vary depending on the felt-based nonwoven fabric to be bonded. Further, except for the vicinity of the putter stroke, the golf ball pop-out prevention wall 17 is configured to be higher than the travel path member, and prevents the golf ball from jumping out.

  The length of this putter training machine is about 2400mm, which is the same length as a normal training machine. Of course, beginners should be able to handle intermediate, advanced, or professional golfers. By changing it, the degree of difficulty can be changed.

  Furthermore, if a bell or sound generator reminiscent of the cup sound is provided at the back of the center line of the felt-based nonwoven fabric that has a center line at the center, the practitioner can have fun and practice.

FIG. 7 is a front view of a practice table where a practitioner performs a trial. It is configured at the same height as the support. It is generally box-shaped and consists of a practice platform lid 9A and a practice platform support 9B. The handle 19 can be detached from the support portion 9B. 9B of the support portion can be inclined by placing a golf ball or a height adjusting hardware in the concave portion 21 and attaching a lid-shaped 9A mainly to the accessory case 20. FIG. 8 is a side view in which the practice base is inclined. FIG. 9 is a side sectional view taken along line cd. There are four recesses, and the golf ball 7 and the height adjusting hardware can be sandwiched to tilt the front, rear, left and right.
