Golf club head and novel method of producing same
Abstract
Abstract A plastic golf club head is formed in two major parts, a body member and a face plate. Complementary dove-tail members are provided on the body member and face plate so that the face plate may be founded by sliding it onto the body member. To prevent movement therebetween when in position, a plastic insert plug is inserted in channels provided in both the body member and face plate in mutual registry. One or more plugs and complementary channels may be utilized. The plugs may be of any desired crosssection. However, when only one plug is utilized, it should preferably have a non-circular cross-section such as rectangular to prevent rotational movement of the face plate. Where two or more plugs are utilized, they may be of any cross-section. A screw is inserted through the body member and engaged in a threaded means provided either in the insert plug or in the body member. The structure permits ready changing of the face plate to provide the club head with various striking contours and angles. The insert plugs are preferably of the same cross-section as the entry ducts of the mold used for molding of the plastic heads, so that the ''''trees'''' from molding of the heads may be used for insert plugs.
