Golf club head set
First Claim
1. A set of golf club heads, comprising at least a first and second golf club head, each having a toe portion, a heel portion, a top portion, a sole portion, a front face bounded by said toe, heel, top and sole portions, and a rear wall bounded by said toe, heel, top and sole portions, a peripheral wall depending from the periphery of said sole portion to define a sole cavity in the sole portion, and two struts extending from a portion of said peripheral wall adjacent said front face to a portion of said peripheral wall adjacent said rear wall, said struts being substantially parallel to each other adjacent said portion of said peripheral wall adjacent said front face and diverging from each other toward said portion of said peripheral wall adjacent said rear wall, said struts defining therebetween and in cooperation with said portion of said peripheral wall adjacent said front face a central portion of said sole cavity, said first golf club head having a loft of less than a loft of the second golf club head, and said central portion of said sole cavity of said first golf club head having a depth of less than a depth of said sole cavity of said second golf club head, wherein a location of a center of gravity in said first golf club head is lower in said first golf club head than a location of the center of gravity in said second club head.

Abstract
A wood-type golf club head comprising toe, heel, top and sole portions, a front face bounded by the toe, heel, top and sole portions, and a rear wall bounded by the toe, heel, top and sole portions, a peripheral wall depending from the periphery of the sole portion to define a sole cavity in the sole portion, and two struts extending from a portion of the peripheral wall adjacent the front face to a portion of the peripheral wall adjacent the rear wall, the struts being in part substantially parallel to each other and in part diverging from each other and defining therebetween and in cooperation with the portion of the peripheral wall adjacent the front face, a central portion of the sole cavity, the peripheral wall being interrupted adjacent the rear wall, such that the central portion of the sole cavity is open to the rear of the club head.
A set of wood-type golf clubs, in which each club in the set has strut members on the bottom of the club defining a sole cavity, and the center of gravity is placed at the optimum location for each club in the set. On the lower lofted clubs the center of gravity is positioned lower in the club, toward the sole. As the loft of the club increases, the center of gravity moves higher, toward the top portion of the club, with the center of gravity highest on the highest lofted club.

13. A set of golf clubs, comprising at least a first and second golf club, each having
a hosel, and a head attached to said hosel, each head having a toe portion, a heel portion, a top portion, a sole portion, a front face bounded by said toe, heel, top and sole portions, and a rear wall bounded by said toe, heel, top and sole portions, a peripheral wall depending from the periphery of said sole portion to define a sole cavity in the sole portion, and two struts extending from a portion of said peripheral wall adjacent said front face to a portion of said peripheral wall adjacent said rear wall, said struts being substantially parallel to each other adjacent said portion of said peripheral wall adjacent said front face and diverging from each other toward said portion of said peripheral wall adjacent said rear wall, said struts defining therebetween and in cooperation with said portion of said peripheral wall adjacent said front face a central portion of said sole cavity, said head of said first golf club having a loft of less than a loft of said head of said second golf club, and said central portion of said sole cavity of said first golf club having a depth of less than a depth of said sole cavity of said second golf club, wherein a location of a center of gravity in said head of said first golf club is lower in said head than a location of the center of gravity in said head of said second golf club head, and said hosel of said second golf club is longer than said hosel of said first golf club.
