Golf club head or other ball striking device having multiple face inserts

Abstract

A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, and a plurality of cavities in the face, each cavity configured to receive an insert. The head may also include a plurality of inserts received within the cavities. The inserts may be made from one or more different materials having different densities. Different inserts having different densities can be connected to the face to customize the weighting of the face, such as to adjust the location of the center of gravity of the face or to change the moment of inertia of the head.

Description

TECHNICAL FIELD[0001]The invention relates generally to ball striking devices, such as golf club heads, having multiple face inserts. Certain aspects of this invention relate to golf club heads having a plurality of cavities, each configured to receive an insert made from a material having desired properties.BACKGROUND[0002]Golf is enjoyed by a wide variety of players—players of different genders, and players of dramatically different ages and skill levels. Golf is somewhat unique in the sporting world in that such diverse collections of players can play together in golf outings or events, even in direct competition with one another (e.g., using handicapped scoring, different tee boxes, etc.), and still enjoy the golf outing or competition. These factors, together with increased golf programming on television (e.g., golf tournaments, golf news, golf history, and / or other golf programming) and the rise of well known golf superstars, at least in part, have increased golf's popularity ...

Problems solved by technology

Despite the various technological improvements, golf remains a difficult game to play at a high level.

Off-center hits may tend to “twist” the club face when it contacts the ball, thereby sending the ball in the wrong direction, imparting undesired hook or slice spin, and/or robbing the shot of distance.

Club face/ball contact that deviates from squared contact and/or is located away from th
