BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to golf clubs and is particularly concerned with a golf putter.
Traditionally golf putters, in common with other golf clubs, have a head secured to a shaft with the head in fixed angular relationship to the shaft. With some putters, the head is in alignment with the shaft, and with others, the head is offset from the shaft to a degree such that with the face of the head positioned directly behind a ball, the axis of the shaft is substantially in alignment with the centre of the ball. For the most part, putter heads are designed to provide a so-called "sweet spot", on the presumption that if the ball is struck by the sweet spot on the head, considerable feel and control is provided over the propelling of the ball in the required direction and over the required length.
There is the reality that most golfers are not sufficiently expert to guarantee striking the ball with the sweet spot, and the presence or the absence of a sweet spot has no particular effect on the degree to which the ball is propelled.
Also, positioning the club with the shaft aligned with the ball centre runs the major risk of unintentional contact between the club head and the ball and the loss of a stroke.
With a putter head in fixed relationship with the shaft, no account is taken of the different statures and different preferences of golfers, and no ability to vary the configuration of the club to allow a golfer to find a configuration that best suits him or her.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a golf putter that assists in overcoming those disadvantages mentioned above.
According to the present invention, a golf club putter comprises a shaft, an offset hosel on the shaft of a length greater than the diameter of a golf ball, and a head secured on the offset hosel. The hosel may be a straight hosel lying at 90.degree. to the axis of the shaft, and, preferably, the head is adjustably secured on the hosel and further preferably, the head has a shape and mass such that it has no sweet spot. Alternatively, the hosel may be a cranked hosel for direct attachment to a golf club head.
The length of the shaft may be relatively conventional, but equally the shaft could be of a length such that with a head on the shaft in proximity to the ground, the free end of the shaft can be gripped in the armpit of the golfer. As a further alternative, a shaft of adjustable length may be provided e.g. telescopic, to provide a first relatively conventional length and a second extended length. A still further alternative is to provide a shaft of relatively conventional length and an extension piece that can be secured to the shaft to provide the longer length to extend to the armpit of the user.
According to a further aspect of the present invention, a golf putter comprises a shaft of a length commensurate with the height of the golfer and whereby the free end of the golf club shaft can be gripped in the armpit of the golfer and the golf club head positioned behind a ball with the golfer in a generally upright disposition, the connection between the golf club head and the shaft being by way of an offset hosel, the length and the height of which is greater than the diameter of the ball, the golf club head being secured to the hosel.
Thus, the head may be angularly adjustable on the hosel to lie at a required obtuse angle to the axis of the shaft, lying to the opposite side of the shaft to the position of the golfer, and the head can be rotated on the shaft from a position where the putter is for right-hand use, to a position where it is for left-hand use. Equally, the head can be rotated about the hosel to a position where it lies at an acute angle to the axis of the shaft and to lie to the same side of the shaft to the position of the golfer.
Desirably, the head is detachably secured to the hosel whereby to allow for the provision of a number of heads for selective attachment to the shaft, for example, to suit different conditions.
With a straight hosel, the head ma
