(a) Field of the Invention
The present invention is related to a golf putter, and more particularly to an adjustable golf putter.
(b) Description of the Prior Art
Most of the golf clubs are each made in one-piece. That is, the grip, the shaft, and the head of a club, iron or wood, are fixed to compromise the specification. However, such a fixed construction often fails a golf player, professional or amateur, to achieve its best hitting status. Particularly when the golf ball is on the green, choosing a right putter could be a headache. Usually, the player would just grab one as desired. It's no way for a play to advance his playing skill. In the design of a putter, the primary concern is given to its specification including lie angle, off set, weight, and length. The lie angle determines whether the human body structure could be incorporated with the putter to put the ball into the hole by cashing out of the optimal pendulum effects. The offset is directly related to the direction the ball travels and thus affects the rolling route of the ball. The weight involves the size of the kinetic energy when the putter hits the ball. If affects most the rolling quality of the ball up or down the slope on the green. Should the putter be adapted with sufficient weight, the optimal stability is paid to the ball rolling on the green. Accordingly, if all those factors described above have been taken into considerations in the design of specification of a golf club, the player would have satisfactory performance on the course and on the green. However, those putters generally available on the market fail to meet those design requirements at the same time. A player is forced to have passive use of a putter without the option to adjust the putter in coping with his own particular needs. He just has to test one putter after another before deciding on one that is better meeting his own swinging habits and style. To a professional or an amateur, all he gets is an impractical answer to a question. Therefore, it is an urgent topic in the manufacturing industry of golf clubs to come up with a putter of a specification entirely suits the individual player.
The primary purpose of the present invention is to provide a putter with an adjustable head that makes easy and fast adjustment of active device of the putter for its offset, lie angle, and weight as desired by the player.
To achieve the purpose, the present invention includes a shaft and a head connect to the shaft. Wherein, the head includes a putting part and an active device connected to the back of the putting part. The active device includes a base, a concave arc part is provided on the center section of the base to accommodate a roller. A sleeve and an adjustment mechanism are respectively inserted to both ends of the roller. A hole is provided on the putting part for the installation of the sleeve, and the roller is connected with a joint to engage the shaft. Two channels are respectively provided on both sides of the base with each channel being fixed with a bolt therein for the installation of one or a plurality of weight and two nuts. The gravity center and the weight of the head are adjusted by the location and the quantity of the weight.
Referring to
A notch 321 is provided to the trough 32 on the base 31 on the distal end of the putting part 21 for incorporation to the adjustment mechanism as illustrated in
Now referring to
By turning the roller 33, the lie angle between the shaft 10 and the putting part 21 is adjusted. When the roller 33 is turned clockwise, the lie angle is increased; or counter-clockwise, decreased. Upon completing the adjustment of the lie angle, the adjustment rod (the bolt) 412 is tightened once again to push against and secure the roller 33 in position. Accordingly, the human body is incorporated to the entire putter to achieve the optimal pendulum effects to put the ball into the hole.
While putting the ball using a putter, the extent of the force applied would cause the ball to defect to either right or left to the assumed route toward the hole. In such case, the offset can be corrected by adjusting the range of the roller 33. In doing so, the adjustment rod (the bolt) 412 is released in the notch 413 of the adjustment block 41 to advance or retreat the roller 33 in the notch trough 32 of the base 31. If the route is deflected to its right due to that the timing to hit the ball varies, the offset should be increased to correct by moving the roller backward. On the contrary, if the route tends to be deflected to the left, simply by slightly advancing the roller. Upon completing the adjustment, the adjustment rod (the bolt) 412 is tightened once again to push against and secure the roller in position.
The present invention achieves the purpose of adjusting its center of gravity and weights. When the putter hits the ball, the extent of the kinetic energy applied in the hitting is sufficient to affect the stability of the rolling ball, particularly so true when putting on a slope on the green. Therefore, the ball rolling on the green would be subject to less jotting applied with the same force when supported by sufficient weights and proper center of gravity of the putter. On the contrary, the insufficient kinetic energy would subject the ball to be checked by the green, resulting in abnormal jotting. Therefore, those multiple weights 39 provided to the bolt 38 of the base 31 can be adjusted for their positions by means of two nuts 391. As illustrated in
It can be appreciated that many other preferred embodiments are possible simply by having changes in certain details. For example, the adjustment rod is made in a form of a pin to be inserted into the notch in the adjustment block to push against the roller for adjustment and restriction to achieve the same purposes sought by the present invention.
