ABSTRACT:
TECHNICAL FIELD
The present invention relates to golf clubs and, more particularly, to a golf club head that has components for adjusting the weight of the club head.
BACKGROUND OF THE INVENTION
Golf clubs are generally selected based on a number of criteria. One of these is the swing weight of the club which takes into consideration the weight of all of the club's components including the head, the shaft and the grip during use. Many golfers would prefer to have the swing weight of their clubs match to their individual needs. This is accomplished by custom-making clubs for the golfer. Since custom clubs are expensive, many golfers do not have the swing weight of their clubs matched to them individually.
Since club makers must limit the number of clubs that they design and manufacture, they limit the number of different swing weights they can offer golfers. It is desirable both to the golfer and the manufacturer to make a club that can have the swing weight adjusted after the club is formed. Various developments have attempted to provide adjustable weighted club heads.
It is desired that a club head is devised which has a simple design but allows customization of the weight of the club head in small increments. However, it is also desirable that this club head is acceptable under the rules of the USGA.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a golf club head with adjustable weight.
Another object of the present invention is to provide a golf club head with weight which is adjustable in small increments.
Yet another object of the present invention is to provide a golf club head where the location of the center of gravity can be adjusted within the club head.
According to the present invention, a golf club is formed to define a hollow interior cavity and includes a first, support wall. The club further includes a chamber connected to the support and extending into the interior cavity of the head. The chamber receives a first flowable material and a second flowable material. The first material weights more than the second material. Since both materials are flowable they can be added and removed from the chamber through an aperture. Depending on the arrangement of the materials, the weight and location of the center of gravity of the club head can be varied.
According to the present invention the second material has a fluid state and a set state.
In one embodiment, the chamber extends from a sole plate of the club head, and the material is arranged in layers.
