20090170628 | Head for Golf Putter - A head for a putter of golf club provides more effective result by improving top spin of golf ball rolling into a hole cup by a putting (striking) on a putting green and thus increasing a straightness that a direction of golf ball and a distance do not change even in a mistaken putting. The head for a golf putter includes a head body united with a shaft endmost part of putter as a kind of golf club and used for putting a golf ball; a putting wire assembled in zigzags with a club face as a putter face of the head body, to extendedly strike the golf ball in a way of surrounding a portion of the golf ball in a putting using the putter; and a tension control member to change a striking sensitivity transferred to the golf ball in the putting. | 07-02-2009 |
20100022326 | GAME APPARATUSES - Game apparatus, e.g., a game racquet or a golf club, with selectively variable and maintainable weight distribution, e.g. by moving material (e.g., liquid and/or solid weight members) within or on the apparatus and selectively positioning the weight(s) and maintaining weight position in or on the apparatus. | 01-28-2010 |
20100048320 | Rotary striking surface on a golf putter - A putter club head is provided with an elongate cavity communicating to the exterior through a rectangular opening in the striking face thereof spaced above the club head lower surface that forms a lower shielding structure to deflect any growth in the course of a putting stroke. A conforming tubular segment is then mounted for rotation within the cavity to expose a portion of its peripheral surface beyond the plane of the striking face generally elevated above the bottom surface to a height corresponding to the elevation of the contact periphery of a golf ball resting thereon. In this manner little or no spin is imparted to the ball when struck by the roller since the lower club surface shields the roller from any moments imparted by the growth covering the green. | 02-25-2010 |
20100298064 | Rotary striking surface in a golf putter - A putter club head is provided with an elongate cavity communicating to the exterior through a rectangular opening in the striking face thereof spaced above the club head lower surface so that the portion of the club head between the cavity opening and the lower surface forms a lower shielding structure to deflect any plant growth in the path of a putting stroke. A conforming cylindrical roller is then mounted for rotation within the cavity to provide a ball striking surface on its periphery generally elevated above the bottom surface to a height corresponding to the elevation of the contact periphery of a golf ball resting thereon. In this manner little or no spin is imparted to the ball when struck by the roller since the lower club surface shields the roller from any moments imparted by the growth covering the green. | 11-25-2010 |
20150343282 | Golf Clubs and Golf Club Heads - A ball striking device has a head with a body member having a face having a striking surface configured for striking a ball, a crown portion and a sole portion connected to the face and extending rearward from the face, where the body member has a void extending inwardly from a rear periphery of the body member, and a rear member connected to the body member and received within the void, such that the rear member forms portions of a crown and a sole of the head. A connection member connects the rear member to the body member to form a joint between the rear member and the body member. A resilient member separates the rear member from the body member, and the resilient member engages the rear member and the body member within the void and is configured to transfer momentum between the rear member and the body member. | 12-03-2015 |
20150343285 | GOLF CLUBS AND GOLF CLUB HEADS - Ball striking devices, such as golf clubs, have a head that includes a face member including a face having a striking surface configured for striking a ball and a rear side located behind the face, a rear member connected to the rear side of the face member, a first connection member connecting the face member to the rear member, and a resilient material separating the rear member from the face member. The first connection member is directly engaged with the rear member, and the club head further includes a first spacer separating the first connection member from the face member. The first spacer is flexible, and the first connection member indirectly engages the face member by compressing the first spacer against the face member. The resilient material engages the rear member and the face member and is configured to transfer momentum between the face member and the rear member. | 12-03-2015 |
20150352412 | GOLF CLUB HEAD - A golf club head includes a head body that has a recess part at a front portion thereof, a face plate that is in a plate shape and arranged in the recess of the head body, a front surface of the face plate being for hitting a ball, and an elastic body that is made of an elastically deformable material and intervenes between the head body and the face plate, the elastic body being fixed to the head body and the face plate so that the face plate is slidable in the recess with respect to the head body. A hardness of the material of the elastic body is ranged between Shore A Hardness 10 and Shore D Hardness 80 (inclusive), and a front side elastic body arrangement surface of the head body to which the elastic body is fixed is not parallel to the front surface of the face plate. | 12-10-2015 |
20160001143 | Dynamic, multi-impact golf club assist device - A dynamic, multi-impact golf club assist device for a golf driver is disclosed. The dynamic, multi-impact golf club assist device golf driver includes multiple pistons slidably mounted in the driver head along an axis of impact of the driver head with a ball. The device may be used with a new or existing driver head provided on a shaft. | 01-07-2016 |
20160067560 | GOLF CLUB HEAD - A golf club head comprising a variable thickness profile comprising a thick central portion; a transition portion; and a thin perimeter portion; wherein said transition portion surrounds said thick central portion; wherein said thin perimeter portion surrounds said transition portion; wherein said thick central portion comprises a center, said center of said thick central portion located equidistant from a heel most portion of said thick central portion and a toe most portion of said thick central portion; wherein said center of said thick central portion is offset from said geometric center of said striking face. | 03-10-2016 |
20160114230 | DOUBLE ACTION GOLF PUTTER HEAD - The present invention is directed to a Double Action Golf Putter Head that when the putter strikes the golf ball the force causes a spring loaded weight to compress the forward spring in a secondary striking action to accelerate the forces against the golf ball along with an optional set of balance adjustment weights on the extensions on either side of the club head. | 04-28-2016 |
