Golf club vibration dampening and sound attenuation system
First Claim
1. A golf club head comprising:
- a front wall including a rearwardly sloped front strike side and a rear side, the rear side having an upper region and a lower region;
a sole portion rearwardly extending from the lower region of the rear side, the rear side and the sole portion defining a forwardly extending cavity and a recess, the recess downwardly extending into the sole portion and interconnected with the cavity; and
a resilient insert assembly positioned in and substantially filling the recess, the insert assembly coupled to at least one of the sole portion and the lower region of the rear side, the upper region of the rear side being generally uncovered, the insert assembly being fabricated of at least one material, the material having a durometer of between 20 on a Shore A hardness scale and 75 on a Shore D hardness scale.

Abstract
A golf club vibration dampening and sound attenuation system including an elongated shaft, a club head, a resilient insert assembly, a dampener, and a grip. The shaft has a distal shaft end and a proximal shaft end. The club head is coupled to the distal shaft end, and includes a front wall and a sole portion. The front wall has a rearwardly sloped front strike side and a rear side. The sole portion rearwardly extends from a lower region of the rear side. The rear side and the sole portion define a cavity and a recess. The recess downwardly extends into the sole portion. A resilient insert assembly is positioned in and substantially fills the recess. The insert assembly is coupled to one or both of the sole portion and the lower region. The dampener is disposed within the shaft and has at least one annular radially extending projection.
