Sole plate internal suspension in metal shells to form metal woods
First Claim
1. A golf club head having a hollow metal shell defining a front wall, a bottom wall, and top and back sides, said bottom wall having an opening therein, a metallic sole plate attached to said bottom wall thereby closing said opening and forming a hollow golf club head, the combination comprising:
- (a) ledge structure integral with the shell and adjacent a rim formed by said opening so that the ledge structure is in the shell hollow, in offset relation to the rim, said ledge structure defined by multiple ledges spaced about said opening and spaced apart from one another, and projecting toward the central region of said opening, said ledges spaced apart in pairs at opposite sides of an upright plane bisecting the head in a front to rear direction,(b) the sole plate located in said opening and supported solely by portions of said ledges spaced from said rim to have close peripheral spacing from the rim,(c) the sole plate being peripherally connected to the shell rim by weld material which fills the spaces between the sole plate and the rim and engages said ledges,(d) upright ribs integrally formed with said front wall, at least a first two of said ledges defined by the lower terminals of said ribs, and(e) said ledges spaced from the outer surface of said bottom wall and toward the hollow interior of the shell so that the sole plate outer surface is flush with said bottom wall outer surface.

Abstract
Ledge structure is made integral with a hollow metallic golf club head, to position a metallic sole plate that closes an opening in the bottom wall of the shell. The ledge structure is defined by multiple ledges spaced apart about that opening and in pairs at opposite sides of an upright plane that bisects the head in a front to rear direction. At least two of the ledges are defined by the lower terminals of ribs integrally formed with the head front wall. The ledges are spaced from the outer surface of the bottom wall so that the sole plate outer surface is flush with the outer surface of the head bottom wall; and the sole plate periphery is connected to the rim of the opening in that bottom wall by weld material in the space between that rim and the sole plate periphery.
