Golf club
First Claim
1. A golf club comprising a hollow head having a face adapted to be resiliently deformed when impacted on a golf ball, a weight mounted in said head, a spring having a first end secured to said weight and a second end secured to an inner wall of said head for normally pressing said weight against an inside surface of said face in a yieldable manner such that said weight moves away from said inside surface of said face under static inertia of said weight while the club is being swung forward.

Abstract
A golf club, which can increase the carry of a ball without increasing the shaft length, has a hollow head in which are mounted a weight and a mechanism for resiliently pressing the weight against the inner surface of the face of the head. In one embodiment, during a forward swing of the club, the weight separates while compressing a spring due to static inertia. When the head impacts the ball, the face dents momentarily and the weight hits against the dented face.

- 4. A golf club comprising a hollow head having a face adapted to be resiliently deformed when impacted on a golf ball, a weight movably mounted in said hollow head, a pair of permanent magnets mounted in said head, said permanent magnets having their magnetic surfaces of the same polarity facing each other so that said weight is pressed against an inside surface of said face by the magnetic repulsion force produced between said magnets, said magnets being arranged such that a distance therebetween decreases when the weight moves during a forward swing of the golf club.
