Golf club having a hollow air filled head
First Claim
1. A golf club comprising:
- a club head having a hollow interior and a hollow hosel attached to the club head, said hollow hosel having a first set of screw threads;
a shaft detachably connected to the club head at the hosel;
a normally closed fluid valve communicating with the hollow interior of the club head and having a second set of screw threads extending therearound, such that said normally closed fluid valve is positioned within said hollow hosel with said first and second sets of screw threads being mated together, said normally closed fluid valve being momentarily opened to permit the club head to be filled with a fluid under pressure, said fluid under pressure being sufficient to prevent the compression of the club head in response to the club head striking a golf ball during the stroke of a golfer; and
a pressure gauge communicating with the hollow interior of the club head to provide an indication of the fluid pressure therewithin.

Abstract
A golf club, such as a conventional metal/wood driver, including a hollow club head, an elongated shaft, and a hollow hosel joined at one end thereof to the club head and connected at the opposite end to the shaft. A normally closed air valve is located inside the hollow hosel. Prior to connecting the shaft to the hosel, the normally closed air valve in the hosel is momentarily opened so that a supply of fluid (e.g. air) under pressure can be delivered to the interior of the club head through the hosel. By virtue of the foregoing, the hollow club head will be filled with air so as to become less susceptible to compression during its impact with a golf ball, whereby a harder striking force will be imparted to the golf ball to enable the golfer to drive the ball a longer distance. A pressure gauge and a pressure relief valve are carried by the hollow club head to provide the golfer with a visual indication of the fluid pressure at the interior of the head and avoid over-pressurized conditions therewithin.

11. A golf club comprising:
-
a club head having a hollow interior and a hollow hosel attached to the club head; a shaft detachably connected to the club head at the hosel; a normally closed fluid valve communicating with the hollow interior of the club head, said normally closed fluid valve being momentarily opened to permit the club head to be filled with a fluid under pressure, said fluid under pressure being sufficient to prevent the compression of the club head in response to the club head striking a golf ball during the stroke of a golfer; a pressure gauge communicating with the hollow interior of the club head to provide an indication of the fluid pressure therewithin; and
an inflatable balloon located at the hollow interior of the club head to receive said fluid under pressure and thereby prevent the escape of said fluid under pressure from the hollow interior, said balloon having an open neck coupled to said normally closed fluid valve, whereby said balloon is inflated with said fluid under pressure by way of said normally closed fluid valve and the neck of said balloon when said normally closed fluid valve is momentarily opened.
