20100029403 | GOLF CLUB - A golf club is described, in which the weight of the head is increased compared with conventional clubs, and in which the upper part of the shaft is also increased in weight, whereby the centre of gravity is disposed in the central zone of the shaft. Preferably, the weight distribution within the head of the club is such that, with the club balanced about its centre of gravity, the shaft will rotate until the face of the club faces upwardly and preferably essentially parallel with the ground whereby, in striking the ball, the inertia of the head is such as to resist any tendency for the club to rotate or twist about the longitudinal axis of the shaft in the hands of the player. | 02-04-2010 |
20100137071 | RELATIVE POSITION BETWEEN CENTER OF GRAVITY AND HIT CENTER IN A GOLF CLUB - A golf club head is provided with a center of gravity positioned within a partial ellipsoid defined in an impact reference frame that has its origin at the hit center of the face of the golf club head. The majority of the partial ellipsoid is located toward the golfer from the hit center and all of the partial ellipsoid is below the hit center in the impact reference frame. | 06-03-2010 |
20100248856 | Weighted and extended golf putter shaft - A stabilizing, weighted golf putter shaft, with the weight embedded within an extended shaft, that conforms with the rules of the United States Golf Association. The weight is adjusted prior to assembly in response to any given putter head so as to move the balance point of the club to a specific and optimum height above the sole of the club when in use by the golfer. | 09-30-2010 |
20110065523 | GOLF CLUB - A golf club having a shaft, a grip, and a head provides improved balance and feel.

The head is secured to the shaft distal end and includes a striking face, a trailing edge, a club head center of gravity, a heel section having a heel section center of gravity, and a toe section having a toe section center of gravity. The heel section center of gravity is forward of the striking face and the club head center of gravity is further from the trailing edge than the striking face. The forward bend section of the shaft projects from the vertical plane at an attachment angle such that the shaft distal end is forward of the heel section center of gravity. | 03-17-2011 |
