Abstract

A golf club head with low peripheral and rearward weighting includes C-shaped and annular weights connected with at least one of the rear and bottom surfaces, respectively, of the head. The weighting within the peripheral weights is adjustable between the heel, rear, and toe portions of the head to customize the weight distribution of the head in accordance with a golfer's swing. The added weight and its orientation increases the moment of inertia of the head and reduces the rotation thereof.

Claims (4)

1. A golf club head of the wood type, comprising:

(a) a metal body including an upper surface, a lower surface, a front ball striking face, a curved rear surface and toe and heel surfaces between said striking face and said curved rear surface; and

(b) a peripheral weight connected with said body on at least one of said rear and lower surfaces in order to increase the moment of inertia of the club head when used to strike a golf ball, said peripheral weight having an annular configuration and being connected with said body lower surface in order to lower the center of gravity of the club head, said peripheral weight including an upwardly extending portion at the rear thereof which extends upwardly over a portion of said body rear surface to distribute more weight to the rear of the club head, and wherein weight is evenly distributed throughout said peripheral weight.

2. A golf club head as defined in claim 1 , wherein at least one of said toe and heel surfaces contains a concave slot for improving the aerodynamic qualities of the head.
