Golf club head having internal impact assembly

Abstract

An improved golf club head having an internal impact assembly configured to improve the direction and distance of travel of a golf ball. The impact assembly is configured to impact the inside wall of the club face at an impact spot immediately after the golf ball is hit to provide a kick to the golf ball so as to direct it along the desired direction of travel. In one embodiment, the impact assembly is disposed in a club head cavity and comprises an internal tube having an impact member that travels inside the tube to contact the impact spot. In another embodiment, the impact member travels in a channel provided in a solid golf club head. Preferably, the impact member is a ball that rolls in the tube or channel. A spring can be provided in the tube or channel at end opposite the impact spot.
