Benefits of technology

[0011]The present invention is a putter with a clubhead that rotates from a first position to strike the ball with a practice face to a second position to strike the ball with a play face. The putter includes a hosel with an attached alignment cap that fits in mated recesses defined by the clubhead so that the shaft and clubhead are fixed as essentially one unit. The clubhead of the present invention also enables one or more weights to be inserted within the clubhead to alter the clubhead's weight. Finally, the putter includes a base plate attached to the bottom of the clubhead to reduce any friction that may be present between the green and the clubhead.

Problems solved by technology

Most of these devices do not conform to the design of clubs specified by the USGA Rules, however, and therefore are used during practice only.
As a result, the putt strokes during play are seldom as good as during practice.
However, with the many rules pertaining to the design of putters, it is difficult to design a club that provides quality training features for practicing and yet can be used for play.
For putters that are convertible from practice to play, one of the most difficult USGA Rules to comply with relates to “providing a putter with a shaft and a head, fixed to form one unit.” The fit between the clubhead and shaft must be extremely tight as to be essentially one unit.
Further, as a golfer's stroke changes over time, the golfer may want to change the weight of the putter.
While a golfer can buy several putters each of a different weight, multiple putters are expensive and each one has its own characteristics that require the golfer to practice with to become accurate.

Embodiment Construction

[0029]The present invention comprises a putter having a shaft 12 attached to a clubhead 11 with a hosel 13. See FIGS. 1-7 and 10-14. The present device may be used with shafts of any length. The hosel 13 includes an alignment cap 18 that firmly secures clubhead 11 to shaft 12 to form a unit that is not conveniently taken apart. The clubhead 11 has two faces, a practice face 14 and a play face 15. Only the play face 15 is used as a striking surface during play, thereby conforming with a USGA Rule that a clubhead have only one striking face. The shaft 12 is attached to the clubhead 11 in such a way that the clubhead can rotate from a practice position to a play position, keeping the shaft in the same position relative to the golfer. See FIG. 1 which shows the practice face 14 of the clubhead 11 in the play position for a right handed golfer. FIG. 2 shows the play face 15 of the same putter. FIG. 8 shows a right-handed golfer 80 making a putt stroke with the practice face 14 and FIG. 9...

Abstract

The present invention is an improved putter that assists a player in perfecting a putt stroke during practice and repeating it with the same club during play. The shaft is attached to the clubhead such that it can swivel from a practice configuration to a play configuration. The putter also comprises a hosel with an attached alignment cap having lobes which matingly engage a series of recesses on the clubhead to secure the clubhead to the shaft. The putter conforms to the Rules of Golf so that the player does not have to change clubs between practice and play. The club may be used for either a right or left-handed stroke.
