Glof club head or other ball striking devices with pole face mold insert

Technical field

The present invention relates generally to have the ball striking device of at least one pole face mold insert, such as glof club head.The glof club head that has by the mold insert of at least a portion ball striking face made with expected performance, that form the bar head that relates in a certain respect of the present invention.

Background technology

Golf receives player miscellaneous---and the player of different sexes and the player of remarkable all ages and classes and technical merit like.Golf is unique in sporting world in a way; Because multiple different players' like this colony can play the movable or project of golf together; Even direct each other contest (for example; Use not good enough score, different service area, or the like), also still enjoy the movable or contest of golf.The TV golf program of these factors and increase day by day (for example; Golf tournament, golf news, golf is historical; And/or other golf program); And the increasing of famous golf superstar, make in the U.S. and even All Around The World scope, quickened the popular of golf in recent years at least in part.

The golfer of each level technical merit tries hard to improve their achievement, reduces their golf scoring, and reaches the achievement of next " rank ".The manufacturer of various golf equipment responds to these demands, and in recent years, on the golf equipment, has seen significant change and improvement.For example, can obtain the golf of various different models now, some balls be designed to fly fartherly and more straight, higher or more flat track is provided, provides better and rotate, control and near feel (especially the fruit mountain range) or the like.

As the unique utensil at active stage chien shih golf, golf clubs has also become many in recent years technical research and improved theme.For example, aspect glof club head, shaft and handle, have on the market and improve in recent years.In addition; Also carried out the improvement on some other technologies; Characteristic and special user's swing characteristic or the characteristic (for example, club mounting technology, ball angle of departure measuring technique or the like) that efforts be made so that various elements and the golf of golf clubs mated better.

Although various technology are improved, want to play out high level, golf remains a kind of recreation of difficulty.For golf, be reliably fly along straight line and on the direction of expectation, golf clubs must satisfy golf and desired destination path meet at right angles (perhaps meeting at right angles substantially).In addition; Golf clubs must satisfy the expectation of golf on club head the position or near it (promptly; In " expectation " perhaps on " best " ball contact position or near it), so as in the direction of expectation reliably along the rectilinear flight and the distance of flight expectation reliably.Off-center hits is easy to " distortion " club face when club face contact ball, thereby ball is sent along the direction of mistake, hook or Slice that generation is not expected, and/or deprived the distance that ball is penetrated.Even club face/ball contact offset straight angular contact and/or be positioned at amount away from a relative pettiness of the ball contact position of club expectation; Golf is launched along the opposite way round; Hook or the Slice do not expected are often arranged, and/or can deprive the distance that ball is penetrated.Therefore, can help the user to make club face keep helping to make ball on the direction of expectation, to fly more directly and more accurate, therefore reach improved and/or distance reliably usually with the rectangular club head characteristic of ball.

Golf clubs must meet at right angles on direction or the path of expectation with golf and contact, so as on the direction of expectation generation straight and penetrate ball accurately.At contact point,, also can cause inaccurate even it is very little to depart from the right angle between club head and the golf.Various glof club heads have been designed to and can have improved golfer's the degree of accuracy through helping the golfer at square stance club head and golf to be met at right angles.A large amount of glof club heads change the position of glof club head weight, so that the position of change club head center of gravity.The position of centre of gravity of glof club head is a factor that determines whether to advance along the direction of wanting golf.In the time of after center of gravity is positioned at the abutment on the contact-making surface, golf is general along straight route operation.Yet; When center of gravity is partial to a side at abutment; Golf is along the flight of undesired direction, and/or along the route operation of left curve or right curve, and ball flight often is called " lifting the ball ", " pushing the ball ", " Draw ", " miss ", " hook " perhaps " Slice ".Similarly, when more than the center of gravity deflection abutment or when following, the route of golf demonstrates the track that moves or climb on more difficult respectively.

The degreeof tortuosity of club head also can depend on the rotary inertia of club head during off-center hits.Usually, rotary inertia is big more, and the distortion of square stance club head is more little.The weight of club head is distributed to the club head edge in proportion more and away from the center, rotary inertia increased.

The common mistake that the golfer repeats to make when waving golf clubs causes some eccentric putt balls, and many other golfers of this mistake also violate similarly.As a result, detect the phenomenon (pattem) in some zone that wherein most of off-center hits appear at club face through regular meeting.For example, detect a phenomenon like this, the not good enough golfer of wherein many height trends towards following heel area and/or the toe zone batting on club face in club face.Other golfers trend towards miss ball in other zones of club face.Because golf clubs generally is designed to or near it, to contact ball at the pole face center, so so off-center hits can make the energy that is delivered on the ball tail off, the distance that ball is penetrated reduces.Also have, relevant with the elasticity of contact point place club face at least in part by energy or speed that golf clubs is delivered on the ball, and can use the measured value that is called " recovery coefficient " (perhaps " COR ") to represent.Current, the maximum COR of glof club head is limited in 0.83 by USGA.Also have, as stated, the degree of the direction of ball flight and club head distortion is also at least in part with relevant about the position of centre of gravity of the rotary inertia of the club head of striking point on the ball and club head during batting.Energy or speed by golf clubs is delivered on the ball are also relevant with the rotary inertia and/or the position of centre of gravity of club head.Therefore, need customization or regulate the rotary inertia and/or the position of centre of gravity of golf clubs pole face, so that square stance provides ceiling capacity transmission and minimal distortion in the maximum face area of off-center hits trending towards occurring.

The distance of ball flight and direction also can be benefited from the influence of club head square stance to the rotation of ball generation significantly.When ball aloft the time, the track that can make ball by the speed and the caused air force of direction of ball rotation is higher or lower or become curve and produce " lifting the ball ", " pushing the ball ", " miss ", " Draw ", " hook ", " Slice " or the like.In addition, when after ball is making impact with the ground, rolling and bouncing, the rotation of ball can change the action (behavior) of ball.For example, highly circle round can make ball slack-off, stop or even back roll at square stance, on the contrary, on revolve or low circling round making ball after making impact with the ground, move farther distance.The various speed and the direction of ball rotation possibly be the results of many factors, comprise the direction of striking point on the ball, square stance club head, the degreeof tortuosity of square stance club head and the position of centre of gravity of club head.The degree of the rotation that the coefficient of friction of club face also can be produced the square stance ball at the striking point on the ball place has appreciable impact.Therefore, need customization or regulate rotary inertia, position of centre of gravity and/or the coefficient of friction of golf clubs pole face, so that realize the ball rotation of desired speed and direction trending towards occurring square stance in the maximum face area of off-center hits.

This device and method are provided, have been used to address the above problem and other problems, and had advantage and the aspect that such does not formerly have in the ball striking device.The following detailed description that to carry out with reference to accompanying drawing of characteristic of the present invention and advantage comes complete argumentation.
