Description
Technical field
The present invention relates to a kind of golf clubs, particularly relate to the hophornbeam and Mobyneb golf clubs with dynamic mass characteristic.
Background technology
Wood and Mobyneb glof club head generally include the front or scope of attack, top, bottom and arch skirt, and this arch skirt comprises heel, toe and back.The scope of attack interacts with golf and contacts.The scope of attack can provide some grooves, sometimes referred to as " score line ", make ball rotation and the object for decoration for auxiliary.For linksman, top is usually configured to have special outward appearance, and provides the rigidity of structure for the scope of attack.The bottom of golf clubs and earth surface in the process swung.
Most of amateur golfers always seeks farther range when they impact, and when especially serving a ball, therefore golf industry is by providing the golf clubs having range and the accuracy wanted concurrently of particular design in response to this.The bar area of bed of wood-type golf clubs is increased, to allow club to have higher rotary inertia (MOI), thus is converted into larger opposing rotatory power when bias impacts.Normally, die model bar head is larger, and its center of gravity will away to move after the scope of attack and the closer to toe, cause impact to fly higher and than expection (for dexterous linksman) more to the right.The inclination angle reducing this larger bar head can compensate this point.Because move hosel axis further away from each other after center of gravity, this larger bar head can cause club to leave gap when contacting, thus causes " miss (slice) " effect (when dexterous linksman and ball is to the right).Offset arm head and/or in conjunction with hook face angle, by helping to compensate this point at square stance " finishing (the squaring) " scope of attack, but usually need to do eliminates " miss " trend more.
In recent years for general golf person provides another technical breakthrough more long-range, be when keep weight constant or by casting compatible thinner outer casing thickness and employing lighter material such as titanium, magnesium and composite make its weight even lighter, make bar large for first watch.In addition, the club scope of attack is also little by little thinning, because the so-called coefficient of resilience (COR) of the collision making to come from golf maximizes by the thinner scope of attack.During collision, scope of attack bounce-back is larger, and the energy be delivered on ball is larger, thus increases the final distance of ball movement.
The known die model bar head distribution of weight that makes improves to make club reduce the method with ball contact gap, generally includes the weight of increase casting body itself or increases weight member at some key position of club.Inquire in some patent documents and how to have made weight member become to be integrated with die model bar head.Such as, the patent No. is 7,186, and 190 U.S. patents disclose a kind ofly comprises multiple glof club head being connected to removable counterweight on rod head noumenon.' the bar head in 190 comprises multiple screw thread mouth that removable counterweight can be made to screw in patent.Although the mass property of golf clubs can be controlled by redistributing these removable counterweights, but quite a few quality must be shifted to the center of bar head by the cylindrical shape of counterweight and their placement locations in golf clubs body, and does not make the peripheral weight of bar head or MOI maximize.In addition, most of cylindrical shaped weight parts are connected on bar head by threaded engagement, and when normally using, these cylindrical shaped weight may rotate and depart from bar head in careless.
As mentioned above, the focus of high not good enough linksman is " miss " trend, and it is partial to except right except making ball, also can apply larger revolving force to ball, reduce overall ball distance further.In order to reduce this trend, weight member is directly arranged in bar head by patent ' 190 instruction.The layout of weight member designed to be able to the rotation reducing ball, and can also apply " Draw " flight of ball from right to left (for the dexterous linksman) to the flight of ball.The design of the offline mode of this ball also contributes to challenge distance type linksman, usually to roll farther distance than the ball with higher rotation speed after initial kiss the earth because have more slow-revving ball.
For by the center of gravity of glof club head in bar head backward and the optional method moved down utilizes composite construction.These composite constructions utilize two kinds, three kinds or more kinds of material with the different physical characteristics comprising different densities.By arranging the material that can provide the strength characteristic met the demands with less weight near the top of glof club head or blade top line, the overall weight of the glof club head of greater part is moved to bottom bar head.This will cause center of gravity downwards and move backward.This method can easily for dorsal muscles formula iron or fairway wood, because it produces inclination angle and strength by contributing to below ball and below.The U.S. the 5th, 720, No. 674 patents show the example of a this compound bar head.The bar head of patent ' 674 comprises the high density material arcuate part being bonded in rear skirt recess.Due to resemble those composites in the bar head of patent ' 674 must by such as welding, punch die or utilize the binding agent of such as epoxy resin to be bonded together, so they often meet with delamination or corrosion after a period of time.The delamination of this composition or corrosion cause the performance of glof club head reduce and bar head can be caused to damage.
Although there is the method for a variety of optimization glof club head mass property, still a kind of glof club head at least comprising dismantled and assembled counterweight is needed in the industry, this dismantled and assembled counterweight has reliable jockey and has low profile, can not protrude into Gan Tou center and bring negative effect to the position of center of gravity to make this counterweight.
Summary of the invention
The present invention relates to a kind of hophornbeam or Mobyneb glof club head, this bar head has the bottom comprising at least one dismantled and assembled weight member.Dismantled and assembled weight member is preferably disposed on towards bottom rear and between the major part heel that concentrates on bar head and toe.Or such as, according to the bar head mass property that requires, center of gravity, inclination angle and rotary inertia, dismantled and assembled weight member also can be arranged at towards the back of bar head and heel or towards back and toe.Preferably, weight member is connected to bar head by non-threaded mode.
