摘要:
Wood-type golf club heads (e.g., drivers, fairway woods, wood-type hybrid clubs, or the like) include: (a) a ball striking face; (b) a club head body engaged or integrally formed with the ball striking face, wherein the club head body includes a removable wrapping element proximal to the ball striking face.
摘要:
A golf club with a shaft and an asymmetrical head, wherein said head has a gravitational center which is further from a trailing edge than said striking face and is disposed on a vertical plane which includes said grip axis.

The present invention relates to a method for determining club parameters for at least one golf club, belonging to a set of golf clubs for a specific golfer, having arbitrary club length Lk,n. The method comprises: selecting club length of a first reference golf club and a second reference club; varying at least one club parameter belong to the group: club weight, club head weight, CG position and weight distribution of the first reference golf club and the second reference golf club; selecting a club parameter value for each selected club parameter. At least one torsional moment PCF, ICF, HCF, GCF is calculated and a relationship is determined as a function of club length. A club length for a first golf club belonging to the set of golf clubs is selected and club parameters for the first golf club is determined based on each determined relationship.
摘要:
A ball striking device (402), such as a golf club head (402), includes a face (412) having a ball striking surface configured for striking a ball and a body connected to the face and extending rearwardly from the face. The body has an impact-influencing structure (430) in the form of a channel positioned on the crown surface of the body. A majority of a force generated by impact with a ball is absorbed by the impact-influencing structure, and a majority of a response force generated by the head upon impact with the ball is generated by the impact-influencing structure. The face may have increased stiffness as compared to existing faces, and may include a stiffening structure to create the increased stiffness, such as a porous or cellular stiffening structure.
摘要:
A golf club such as a putter having a club shaft with an upper end and a lower end and a longitudinal axis; a club head on a lower end of the shaft and with a lie angle between the shaft and the club head; and a grip on an upper end of the shaft. The grip provides an increased effective lie angle. The lie angle between the shaft and the club head is in the range from about 67° to about 75° and the effective lie angle is in the range from about 76° to about 85°. The grip improves the performance of the golfer.
摘要:
A sports racquet including a handle assembly coupled to and longitudinally extending from a head portion. The handle assembly includes an elongate tubular shaft, a pallet positioned over the shaft, and a plurality of generally planar support members. The pallet is positioned over the shaft and has an outer surface that defines a plurality of longitudinally extending flats. Each of the flats has a length and a width. At least two of the flats define respective elongate recesses. Each of the recesses having a maximum recess width that is less than the width of the respective flat. The support members are positioned within the respective recesses.

The object of the present invention is a puck (1) and a stick (5) for an ice hockey game. The surface (2) of the puck (1) and the blade (5b) of the stick (5) are coated with a coating material (3, 6) which improves friction or attachment.
摘要:
An example system and method is provided for detecting a moment of impact and/or strength of a swing based on moving a hand-held device including an accelerometer arrangement. A moment and a magnitude of simulated striking of the object are determined based on one or more accelerometer arrangement outputs resulting from the moving of the hand-held device. Using one or more of aural, visual and tactile outputs, the striking of the object is simulated in accordance with the determined moment of simulated striking and the determined magnitude of the simulated striking.

A changeable grip 12 for a shock imparting implement has a gripping sleeve 18 positioned on a handle sleeve 15 attached to a handle 14. A lower end of gripping sleeve 18 abuts a ledge 28 integrally formed in the handle sleeve 15. A threaded cap 20 compresses the gripping sleeve 18 against the ledge 28 to secure the grip 12 to the handle sleeve 15. Optional splines 40 on an outer surface of the handle sleeve 15 meshing with channels 42 in the gripping sleeve 18 function to prevent slippage or rotation during use.
