A ball striking device includes a ball striking plate having a front surface configured to strike a ball and a rear surface opposite the front surface. The ball striking plate has a desired-contact region and a perimeter. One or more spoke-like reinforcement ribs may be located on the rear surface and may radiate away from the desired-contact region toward the perimeter. At least one of the spoke-like reinforcement ribs may be located in an upper-toe quadrant or in an upper-heel quadrant of the rear surface. One or more encircling reinforcement ribs may be located on the rear surface. The one or more encircling reinforcement ribs may be at least partially encircling the desired-contact region. A thickened portion of the ball striking plate may be positioned behind the desired-contact region of the ball striking plate. The ball striking device may be a golf club head.

A cavity back golf club head having a bridge member and a damping element is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a damping element extends from the sole portion of the cavity back golf club head to the bridge member to define a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the damping element extends from the top portion of the cavity back golf club head to the bridge member. The damping element may reduce the vibration and sound of the golf club head upon impact with a golf ball.

A device for changing the mass characteristics of a golf club may include a first movable mass. The device may also include a first movable mass guide configured to accommodate longitudinal travel of the first movable mass along the golf club shaft. The first movable mass guide may not extend beyond the distal end of the golf club shaft. The golf club head may include a second movable mass and a second movable mass guide that accommodates travel of the second movable mass.

A golf club sleeve for use with various golf club structures is presented. The golf club sleeve may have an airfoil shaped cross section and may extend over at least a portion of the shaft of the golf club to reduce drag associated with the shaft during a golf swing, thereby increasing swing speed. The golf club sleeve may be rotatable relative to the shaft of the golf club to orient itself during a swing in order to improve air flow over the sleeve.

Golf club sleeve and golf clubs for use therewith

Iron golf clubs heads and clubs include: (a) a ball striking face; (b) an opposite rear surface; (c) a sole portion extending rearward from the ball striking face and defining a cavity having an open upper portion; (d) an insert element mounted in the cavity, wherein the insert element includes at least one weight port; and (e) a weight member mounted in the port. The insert element may substantially fill the cavity to dampen vibrations and/or noise when a ball is struck. Additionally, the insert element may allow the weight(s) to be selectively placed to enable customization and tuning of the overall weight of the club head (e.g., for swing weighting purposes, for ball flight control purposes, etc.). Methods of making such club heads and clubs also are described.

Iron type golf clubs and golf club heads having weight containing and/or vibration damping insert members

A cavity back golf club head having a bridge member is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a wall extending from the sole portion of the cavity back golf club head to the bridge member defines a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the wall extends from the top portion of the cavity back golf club head to the bridge member.
