Golf club head with a high coefficient of restitution
InactiveUS6960142B2Increase ball speedAnalysing solids using sonic/ultrasonic/infrasonic wavesGolf clubsBall impactCoefficient of restitution
The present invention relates to a golf club head provided with a face and a body. The face has a central zone and a intermediate zone adjacent and surrounding the central zone. The central zone has a first flexural stiffness and the intermediate zone has a second flexural stiffness. The club head face is configured and dimensioned such that the first flexural stiffness is significantly greater than the second flexural stiffness such that upon ball impact with the face, the intermediate zone exhibits substantial deformation so that the central zone moves into the club head. At the same time, the central zone exhibits minimal deformation so that it moves into and out of the club head as a unit. Furthermore, the face exhibits a high coefficient of restitution.

Golf club head with variable flexural stiffness for controlled ball flight and trajectory
InactiveUS7041003B2Increase ball speedAnalysing solids using sonic/ultrasonic/infrasonic wavesGolf clubsEngineeringControl zone
The present invention relates to a golf club head with a hitting face. The hitting face comprises a directional control portion, which has at least two zones with different flexural stiffness, such that when the hitting face strikes a golf ball the two zones deform differently to selectively control the direction of the flight of the golf ball. The directional control portion may comprise an upper zone and a lower zone, where the upper zone has a lower flexural stiffness. Alternatively, the lower zone has a lower flexural stiffness. On the other hand, the directional control portion may comprise a left zone and a right zone, and either the left or right zone may have a lower flexural stiffness to selectively control the lateral launch angle either to the left of right. The hitting face may further comprise a central zone disposed within the directional control zone, wherein the central zone has a flexural stiffness of at least about three times greater than the flexural stiffness of the directional control zone.

Ball bats and methods of making the same are disclosed whereby the handle and barrel members are separate structural components, and whereby the handle member is of sufficient length to extend through the hollow barrel member. The handle member is connected to the barrel member at its proximal and distal ends by proximal and distal connectors. The connection between the handle member at the proximal end of the barrel member is by means of an elastomeric proximal connector. The connection between the handle member and the distal end of the barrel member is accomplished by means of a rigid distal connector. The rigid connection of the handle member's distal end to the distal end of the barrel member and the elastomeric (flexible) connection between the handle member and the proximal end of the barrel thereby allows the handle member to flex substantially across its entire length during ball impact thereby improving ball speed and distance off the bat when struck.

A golf ball-forming composition, golf balls prepared from the composition and the process for preparing thereof. The golf ball-forming composition is composed of the following: polyvinyl alcohol resin 5-80 wt %; filler 0-90 wt %, natural high polymer material 0-60 wt %, and plasticizer 5-50 wt %. The filler is the common filler known by the skilled person in the art; the natural high polymer material is celluloses or amyloses; the plasticizer is the common substances used by the skilled person in the art. The golf ball-forming composition is water soluble and biodegradable. The water soluble and biodegradable golf ball has a hollow inside, and has a surface which is disposed with at least one through hole communicated with the hollow. When the golf ball is hit into water, water will enter the hollow via the through hole, thereby increases the contact area between water and the ball and accelerates the dissolution of the ball, so that the ball may eventually completely biodegraded in the environment.

Golf club
ActiveUS7686705B1Moment of inertia is maximally alteredLittle effectGolf clubsStringed racketsMoment of inertiaWeight management
An improved design for a golf club shaft and method increases stroke accuracy by significantly reducing stroke take-back distance. A ball traveling at a set initial velocity will travel a different distance on different parts of the course due to the friction of the grass on the ball which varies in response to height and moisture level. An inline weight management system that allows the moment of inertia of the club to be adjusted in a predictable manner. An increase in the moment of inertia translates into an increase in force which is in turn proportional to club velocity and resulting ball velocity. As green speed decreases, moment of inertia can be increased so that a stroke with a uniform take-back distance will deliver a shot that travels as far as the same stroke would deliver on a fast green.

InactiveUS20120015756A1Reduce widthLess aerodynamic dragGolf clubsRacket sportsHigh momentumMomentum transfer
The wood or iron golf club has a reduced shaft width transverse to the direction of motion and a greater shaft depth parallel to the direction of motion, therefore, has a reduced frontal area that creates less aerodynamic drag and a higher resistance to bending opposite the direction of motion, respectively. The low drag rigid shaft allows higher head velocity, higher momentum transfer to the ball, higher ball velocity, and longer more accurate drives then current clubs with elongated cone shaped symmetrical shafts.The wood or iron gulf club shaft-head configuration has the shaft axis intersecting the common axis of the horizontal component of the line of play and the head center of gravity. The club therefore does not create a torque about the shaft axis during the swing motion or ball impact and facilitates greater accuracy and consistency in hitting the optimum point on the ball with the optimum point on the club head.

The game apparatus is played on lanes such that each lane is distinctly different such as Miniature Golf holes wherein ten lanes are played sequentially, as Miniature Golf, such that each lane comprises a frame and the ten played lanes comprises a single game or string. The game apparatus is scored the same as Candlepin and Duckpin bowling. Each unique lane is not like a bowling alley but can be free formed in different shapes, lengths and proximity to one another as found in Miniature Golf. The game apparatus can be installed in a center where more than one 10 lane set can be located. In addition, the each ten lanes of the apparatus can be set up in the same or differing themes such as pirates, jungle, western, etc. The bowling game apparatus can be accomplished without the need for expensive wooden or synthetic lanes that must be critically leveled and assiduously maintained. Further, there is no need for special shoes for the players to prevent damage to the playing surfaces. Other features found in Miniature Golf and Pinball machines make the game more fun, faster and exciting. The game can be challenging for adults but permits children to compete on a equal footing with adults; and gives the players the feeling that they playing a bowling type of game while standing inside a Pinball machine.
