Description

Glof club head

Technical field

The utility model relates to a kind of glof club head with high the moment of inertia (Moments of Inertia).

Background technology

Produce desirable golf strike effect and need possess following two key factors: the first, the center of gravity of the striking point on the ball in glof club head front, glof club head center of gravity and golf is arranged in line; The second, the glof club head front must be vertical with the flight path that golf is wanted.When hitting, if the center of gravity of striking point on the ball, glof club head center of gravity and the golf in glof club head front does not form desirable straight line, then the energy of transporting to golf from the golf clubs overhead pass can't reach maximum, and meaning has promptly shortened the flying distance of golf.And when hitting, if the glof club head front can't be vertical with the flight path that golf is wanted, the flight path that will cause the golf ball flight path deviation to be wanted then.

Please refer to Fig. 4, if the striking point on the ball 402 in glof club head front 408 is towards the toe skew of glof club head, cause striking point on the ball 402, the glof club head center of gravity 404 in glof club head front 408 not to form straight line with the center of gravity 406 of golf, then except the flying distance that shortens golf, glof club head also will produce turning effort because of striking point on the ball 402 skews, make glof club head when hitting, rotate the accuracy that influence is hit around axle by the glof club head center of gravity.

Be understandable that, for an experienced golf striker, it is very difficult reaching above-mentioned desirable golf strike effect, therefore need provide a kind of new-type glof club head, to reduce the turning effort that the striking point on the ball skew is produced.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of glof club head of high the moment of inertia, provides glof club head preferred rotary damping characteristic with higher the moment of inertia, reduces the turning effort that the striking point on the ball skew is produced.

To achieve these goals, the utility model provides a kind of glof club head, comprises to have in order to the groove that hits golf to hit the front in district, the back side with respect to the front, the top that forms the higher part of glof club head, low bottom, the toe that forms the glof club head leading portion, the heel of formation glof club head back segment and the bar neck with club fixing hole partly of formation glof club head.The surface of toe and front join in first edge, and toe stretches out by first edge along the direction away from the bar neck, exceed outside the front so that be positioned at the projection essence that comprises the toe on the positive plane.And the surface of bottom and the back side join in trailing edge, and the surface of bottom and toe joins in second edge, and wherein the angle between the trailing edge and second edge is less than 90 degree.

Another embodiment of the present utility model provides a kind of golf iron head, comprises to have in order to the groove that hits golf to hit the front in district, the back side with respect to the front, the top that forms the higher part of golf iron head, low bottom, the toe that forms the golf iron head leading portion, the heel of formation golf iron head back segment and the bar neck with club fixing hole partly of formation golf iron head.The surface of toe and front join in first edge, and toe stretches out by first edge along the direction away from the bar neck, exceed outside the front so that be positioned at the projection essence that comprises the toe on the positive plane.And the surface of bottom and the back side join in trailing edge, and the angle between between a trailing edge and a tangent line is less than 90 degree, and wherein this tangent line and toe are tangential on toe a bit of outer most edge when overlooking from top to bottom.

Another embodiment of the present utility model provides a kind of golf iron head, comprises to have in order to the groove that hits golf to hit the front in district, the back side with respect to the front, the top that forms the higher part of golf iron head, low bottom, the toe that forms the golf iron head leading portion, the heel of formation golf iron head back segment and the bar neck with club fixing hole partly of formation golf iron head.The surface of toe and front join in first edge, and toe stretches out by first edge along the direction away from the bar neck, exceed outside the front so that be positioned at the projection essence that comprises the toe on the positive plane.And the surface of bottom and the back side join in trailing edge, and wherein trailing edge has at least one central part towards positive indent.
