The present invention relates to a golf club, and more particularly to a golf putter with a guide ball to improve the putting stroke of the golfer.

Golf is a popular sport and has become a recreation that many people enjoy. For decades, technological advances in golf balls, golf clubs and golf courses have led to improvements in golf scores. And it has been recognized that golf putters will make tremendous advances in the golfer's operation because they play a key role.

Putters play an important role in improving the golfer's score. Most conventional putters have a shaft attached to the putter head with a flat heating surface for hitting the ball. Since most putters have a flattened plane, the golfer swings the body of the putter from side to side, relatively horizontal to the "line of sight," the line from the ball to the hole. A common design is to have a bottom surface that is used to correspond to ground.It is desirable to eliminate the potential interference by making very little or no contact with the bottom surface of the putter during the putting stroke. In preferred putting strokes, the user typically raises the putter slightly so that the heating surface does not touch the putting surface, commonly referred to as green, thus many different types of golf putters improve the putting stroke of the golfer. It has been developed to make.

US Pat. No. 5,409,220 issued to Lombardo teaches a putter with a shaft configured to be adjusted to the desired angle. Another golf putter is U.S. Patent No. 4,688,799 issued to Johnson, which has a rotatable rotating roller mounted to either the front or heel portion of the golf club. The roller prevents the head from rising and rubbing against the ground so that the heating surface does not contact the putting green during the stroke. However, a disadvantage is that a single roller does not improve the straight motion of the golfer's putting stroke.

Another putter is US Patent No. 3,319,964 issued to Steinburg. Steinberg teaches a practice putter with an axis extending across the head horizontal and a wheel rotatable on each end of the axis. As long as the stroke is in the direction of the turning wheel, the wheel will cause the fitting surface on the green to strike in a straight line. The disadvantage is that there is no indicating means to determine whether the wheel is rotating at the maximum speed of the hit. Since the user must rely only on observing the wheel, he will notice that the wheel rotates and the user's focus drops off the focused focus from the golf ball and the neckline.

No prior art teaches the improved putter taught by the present invention.

Accordingly, the main object of the present invention is to provide a golf putter that can improve the ability of a golfer by improving straight and smooth putting strokes. Another object of the present invention is to provide a golf putter that can improve the golfer's ability by maintaining a constant desired speed of the putting stroke.

The present invention relates to a putter that improves a golfer's putting game. The putter has a conventional shaft connected to an improved head. The head should essentially have a flat heating surface, top surface and bottom surface for hitting the golf ball. A portion of the head extends rearward and has an opening therein to receive the guide ball. The top plate forms part of the top surface at the head and is detachably attached to the head. The top plate can be opened and closed to insert and remove the ball into the cavity. The ball has the same size and dimensions as the size and dimensions of a conventional golf ball. The upper opening is formed through the upper plate connected to the cavity, and the lower opening is also defined through the lower surface connected to the cavity. The ball is rotatably mounted on an axis within the cavity, and the ball partially protrudes out through both the upper and lower openings to be visible from the top and bottom. This ball rotates back and forward in a direction perpendicular to the heating surface.

The neckline is indicated on the upper surface of the head perpendicular to the heating surface, and the dashed line extends around the ball in a predetermined manner so that it is co-linear with the neckline of the upper surface. If the ball rolls, the dashed line will appear as a solid line that is collinear with the neckline. The neckline helps the golfer improve the straight putting swing when hitting the target golf ball. This putter helps the golfer improve control of the ball's spinning putting stroke speed as long as the ball is in contact with the putting surface, and as long as it is moving at a predetermined speed limit.

In view of the foregoing and further objects and advantages, the present invention represents the device described below, as well as the combination of devices and arrangement of components, shown below in the accompanying drawings, for example in accordance with a preferred embodiment.

1 shows a putter 10 of the present invention. The putter 10 includes a shaft 12 connected to the head 15. The head 15 has an essentially flat heating surface 17, an upper surface 20 and a lower surface 22 for hitting a golf ball. The upper plate 25 forms a portion of the upper surface 20 on the head 15 and is detachably attached to the head 15. The head 15 has a portion 19 extending rearwardly. The head 15 has an opening defined therein to receive the guide ball 30 therein. Guide ball 30 has the same size and dimensions as the size and dimensions of conventional golf balls. In the embodiment shown in Figures 1 to 3, the guide ball 30 is a conventional golf ball having all the dimples that the golf ball has. Also, in the embodiment shown, the cavity is arranged in the part 19 extending rearward of the head 15.

The upper opening 33 is formed through the upper plate 25 connected to the cavity, and the lower opening 35 is also defined through the lower surface 22 connected to the cavity. The guide ball 30 is rotatably mounted in the cavity and partially protrudes out through both the upper opening 33 and the lower opening 35. In this way, the guide ball 30 can be visible from the top and bottom of the head 15. The guide ball 30 protrudes sufficiently from the lower opening 35 so that the lower surface 22 of the head 15 rises above the putting surface when the guide ball 30 rotates on the putting surface. In this embodiment shown in FIGS. 1 to 3, the drilled hole 38 extends through the ball, and ring-shaped bearings 40 are disposed at each end of the drilled hole 38. The guide ball 30 is mounted on the spring loaded shaft 45 extended through the drilling hole 38 and the bearing 40. Each end of the spring loaded shaft 45 is rounded and mounted to a corresponding curved portion 48 formed in the wall of the cavity in the head 15. In this way the guide ball 30 rotates back and forth in the vertical direction with respect to the heating surface 17. In order to remove the guide ball 30, the user removes the guide ball 30 by removing the upper plate 25 and pressing out the spring-loaded shaft 45 inward from the corresponding curved portion 48. In order to install the guide ball 30 again, the user simply opens the upper plate 25 and presses the spring loaded shaft 45 therein to the corresponding curved portion 48 and closes the upper plate 25.

The head 15 also has a neckline 50 extending across the top surface 20 of the head perpendicular to the heating surface 17. In the illustrated embodiment, the neckline 50 extends across the top plate 25. The dashed line 53 extends around the guide ball 30 in a predetermined manner such that the dashed line 53 is on the same line as the neckline 50 of the upper surface 20. When the guide ball 30 rotates, the broken line 53 will appear as a solid line existing on the same line as the neck line 50. Neckline 50 helps golfers improve straight putting swings when hitting a target golf ball. In the preferred putting operation, the neckline 50 should move in a straight direction.

In the second embodiment shown in FIGS. 4-7, the putter 10 includes a shaft 12 connected to the head 15. The head 15 has a heating surface 17 and a portion 67 extending rearwardly. The pair of side walls 64 form part of the rearwardly extending portion 63. The guide ball 30 is rotatably mounted between the pair of side walls 64. As shown in Figs. 1 to 3, the drilling hole 38 extends through the guide ball 30, and the ring-shaped bearing 40 is disposed at both ends of the drilling hole 38. The guide ball 30 is mounted on the spring loaded shaft 45 extended through the drilling hole 38 and the bearing 40. Each end of the spring reload shaft 45 is rounded and mounted to a corresponding curved portion 48 formed in each side wall 64 of the portion 63 extending rearward of the head 15.

As shown in FIGS. 1-3, the guide ball 30 of the second embodiment has the same size and dimensions as the size and dimensions of a conventional golf ball and extends across the upper surface 20 of the head 15. It has a dashed line 53 on the same line as the neckline 50 and extends around the guide ball 30. In addition, the rearwardly extended portion 63 has a bottom surface 68 having an opening 70 through the bottom surface 68. An edge 71 surrounding the opening of the bottom surface 68 is tapered to be inclined downward as in the embodiment shown in FIGS.

8 to 12, in the third embodiment of the present invention, the portion 63 extending rearward of the head 15 of the second embodiment is formed to be connectable with the front head portion 75. FIG. In this embodiment, the front head portion 75 necessarily has a flat rear surface 77, to which the rear extended portion 63 is attached. Each end of the side wall 64 is provided with an attachment device 79 so as to be attachable to the front head portion 75. In the embodiment shown in FIGS. 8-12, the attachment device 79 has a threaded pin 80 mounted on the top plate 85 protruding from the side wall 64. In addition, each side wall 64 has a lower plate 88 protruding below the threaded pin 80 on a corresponding upper plate 85. Turn the threaded pin 80 in the predetermined direction so that the threaded pin 80 presses against the lower plate 88 so as to be between the lower plate 88 and the protruding lower surface 89 of the rearwardly extended portion 63. By tightening the rear face 77 of the front head portion 75, the rear portion 63 extended to the front head portion 75 can be attached. In the embodiment shown in FIGS. 8-12, a spring 90 is disposed below each bottom plate on the bottom surface 89 to force each corresponding bottom plate 88 upwards. .

While the preferred embodiments of the present invention have been disclosed and illustrated for the purpose of clarifying embodiments, those skilled in the art to which the above description pertains, many modifications, alternatives and modifications to the disclosed embodiments are defined by the claims below. It will be clear that not beyond the scope and ideas.

The putter of the present invention helps the golfer to develop to be ideally flat and straight and to consistently push the putting stroke. In fact, a right-handed golfer catches a putt and swings from right to left to hit the target ball. Each putter has a sweet spot on the heating surface. This spot is typically on the center of the heating surface where the golfer wants to hit the golf ball for the most accurate results. In the most ideal putt, the sweet spot is in contact with the center of mass of the golf ball. On the putter, the sweet spot is centered on the heating surface. To use the putter properly it is necessary to roll the head across the putting surface on the freely rotating ball. The guide ball guides the head in a straight line. In addition, the guideball assists the golfer in positioning and maintaining the head at an appropriate level on the putting surface. The golfer needs to bring the guide ball into contact with the putting surface to cause rotation of the guide ball during the putting swing.

As the ball touches and rotates the putting surface, the sweet spot of the heating surface will hit the target golf ball. The putter can also help to improve the desired putting stroke by controlling the speed of the backstroke (after the head swings from the golf ball) and the front stroke (the moment the head swings toward the golf ball). The putter's guide ball rotates only within the desired speed limits of the backstroke and front stroke. If the stroke is faster than the preset speed, the guide ball will not rotate. The user will know by checking the broken line in the guide ball to see if the ball is rotating. If it remains dashed, the guide ball does not rotate. If the ball rotates, the dashed line will look like a solid line on the same line as the solid line on the top surface of the head.

The average golfer uses this putter properly, while the golfer's putting accuracy will be maximized through advanced good habits. Also, by removing the ball from the head, the golfer can use the putter without the assistance of the ball.
