Golf club head having a device for resisting expansion between opposing walls during ball impact
First Claim
1. A golf club head having a sole, a crown, a toe, a heel and a hitting surface all forming an interior cavity and being connectable to a golf club shaft by an integral hosel, the head comprising:
- a tensioning member located in the interior cavity between apertures at opposing locations on the sole and crown for increasing compression therebetween and being affixed at respective ends to said opposing locations, said tensioning member being in a state of selected tension to apply a selected compressive force between said sole and said crown.

Abstract
An improved golf driver club head wherein each driver club head has a tensioning device, which places the peripheral/outer structure of the club head in compression; thereby, resulting in a stronger, more rigid club head structure. In the preferred embodiment, the tensioning device comprises an elongated cylindrical member having respective end members. The top and bottom surfaces of the golf club head are each provided with a cylindrical depression or recess and an aperture or passage at the lower end of the depression. The passages are just large enough to accommodate the tensioning device, but are too small to pass the respective end members. During club head manufacture, the length of the device is selected to apply a compressive force between the head surfaces. Fine adjustment is accommodated by a threaded end member. The actual compression force may be selected to yield the best performance depending on the geometry, structure and material of the club head.

6. A method for configuring a golf club head for increased compression and thus resisting deformation between two opposing walls defining an internal cavity, the deformation occurring upon impact with a golf ball;
- the method comprising the steps of;
a) positioning an elongated tensioning device between apertures at said opposing walls within said internal cavity;
b) attaching the respective ends of said tensioning device to said opposing walls; and
c) applying a selected tensioning force to said tensioning device to compress said opposing walls toward each other. - View Dependent Claims (7, 8)
