Golf driver with selective head weighting system

Abstract

An improved golf driver head design is presented which permits golf drivers to be adjusted to correct the swing characteristics of most golfers. A system of attachable weights is shown which make it possible to adjust golf club swing characteristics at the factory simply and economically. The invention is cast from very light weight metals to allow the maximum amount of weight adjustment within the head while keeping the head weight to a minimum.

1 . A golf driver head comprised of a driver head upper section, a driver head lower section, a hosel piece, a plurality of weight attachment points, and a plurality of golf club weights, 
 the driver head upper section possessing an outer and an inner surface, the driver head upper section inner surface possessing a plurality of strategically-placed weight attachment points, the weight attachment points in the shape of a bulge in the material of the driver head upper section inner surface, The driver head upper section possessing a hosel pass-through hole, the hosel pass through hole a circular hole passing through the driver head upper section,    the driver head lower section possessing an outer and an inner surface, the driver head lower section inner surface possessing a plurality of strategically-placed weight attachment points and a hosel mounting point, the weight attachment points and the hosel attachment point in the shape of a bulge in the material of the driver head lower section inner surface, the hosel mounting point placed such that when the driver upper section and driver lower section are assembled, the hosel mounting point is directly beneath the hosel pass-through hole,    the golf driver head assembled by drilling a hole in the hosel mounting point in line with the hosel pass-through hole, selecting certain of the weight attachment points to be prepared for placing of the golf club weights by choosing the characteristics of swing that the golf club head will produce, preparing the weight attachment points on the golf club head upper and lower sections that when weighted will produce those characteristics, attaching the weights permanently by means of a weight attachment means to the prepared weight attachment points, attaching the driver head upper and lower sections to each other by a golf club head assembly means, then attaching golf club weights at the weight attachment points, then permanently affixing the golf club weights with the weight attachment means.    
   
   
       2 . The golf driver head of  claim 1  where preparing the weight attachment points on the golf club head upper and lower sections consists of drilling a receiving hole into the weight attachment point from the outer surface of either or both of the golf club head lower and upper sections.  
   
   
       3 . The golf driver head of  claim 2  where the weight attachment means is a combination of screw threads on the golf club weight and permanent adhesive that holds the individual weights in the receiving hole.  
   
   
       4 . The golf driver head of  claim 1  where both the golf club head upper and lower sections are comprised of magnesium or titanium.
