I. according to the general introduction of example golf club head of the present invention, golf clubs and method

Even there are many improvement of golf pole technology in recent years, the golfer still can not obtain the good distance of golf driving aspect, and wherein the golf center of being departed from striking surface impacts.Therefore, aspects more of the present disclosure relate to glof club head, and it comprises interchangeable quality loop, and this quality loop can help to impact with eccentric a part of striking surface the golfer lets golfer's loss distance minimization on the golf.

Usually, the golfer can attempt to impact golf with the center of golf clubs head batting surface.Core through with the glof club head body impacts golf, and golf is usually with respect to the speed of the swinging big as far as possible distance of advancing.Yet, if impact golf with eccentric a part of glof club head body, far (being meant certainly) that kind flew when golf was impacted by core not as it usually if the speed that swings is identical.This is because when mistake taking place impact (for example when impacting golf with the toe end of glof club head body or heel end), the head of golf will reverse and so expend the energy that should give golf.For limit because of mistake impact generation apart from loss, glof club head should be by restriction as much as possible mistake reversing during impacting.

Rotary inertia (MOI) is a kind of physical property, and it is meant the change of target around the axis angle motion.As being applied to glof club head, MOI typically refers to the ability reversed of club head opposing around known axis (normally striking surface plane).The high more then club head of MOI can be resisted more and reversed, and the low more then club head of MOI is easier to surrender to reverse on the contrary.Therefore, during mistake impacts, have reversing that the glof club head of high MOI will be still less, therefore expend still less owing to reverse the energy that causes.Therefore, energy can be endowed golf, and is farther so that golf is advanced.In fact, the MOI of glof club head is high more, then the distance that loses when impacting of mistake still less (club head has bigger " tolerance ").Therefore, for glof club head, advantageously have high relatively MOI, thereby glof club head will be in mistake when impacting more " tolerance ".

A kind of exemplary process that increases glof club head MOI is to let the quality of glof club head as much as possible move on to the periphery of glof club head.For Wood-type golf club head, the inside of glof club head normally hollow and the glof club head body comprise wall, said the wall extremely thin usually scope of (for example several millimeters).Therefore, multimass is meant the periphery at glof club head in order to incite somebody to action more, and mass member or counterweight can be engaged in the some parts of glof club head, for example the wall of glof club head.For example, according to some aspects of the disclosure, interchangeable quality loop can be engaged in one or more parts of glof club head body.Interchangeable quality loop is engaged with this part of club head with the more multimass of glof club head towards the edge of glof club head body respectively, and this can increase glof club head and get MOI.As stated, this can provide the bigger resistance that reverses, and therefore is provided at the bigger tolerance when by mistake impacting.

Although on foursquare basically wood club head, show in 2D at Fig. 2 A, same qualification may be used on more how traditionally shaped Wood-type golf club head (for example shown in Fig. 1 and the 3-7).

It is to be oriented at glof club head body 102 to be positioned at that part of glof club head top surface that can see when on club head, directly looking down when it designs bar head inclination angle (the bar head inclination angle of this specification for example is 60 °) that " the bizet part " of glof club head is defined as.It is that part of glof club head lower surface that when glof club head body 102 is oriented to seeing of on club head, directly making progress when being positioned at its design bar head inclination angle (the bar head inclination angle of this specification for example is 60 °), can see that " bar bottom divide " of glof club head is defined as.When club is orientated as described above, can be through arranging that along bizet part and bar bottom branch the floor projection line finds the peak of club head bizet part and the minimum point that club head rod bottom is divided respectively.

According to aspects more of the present disclosure, glof club head body 102 can comprise can be removed and interchangeable quality loop 201, and this quality loop is configured to be engaged in glof club head body 102.Fig. 3 is the embodiment of interchangeable quality loop 201.As shown in Figure 3, quality loop 201 can be circular or oval-shaped.Yet, quality loop 201 can form various other geometries (for example the square, rectangle, leg-of-mutton, etc.).Certainly, the annular shape of quality loop 201 will be provided at the opening at quality loop 201 centers.

According to aspects more of the present disclosure, interchangeable quality loop 201 can be configured to be engaged in the outside of glof club head body 102.For example, when quality loop 201 glof club head bodies 102, quality loop 201 can be configured to form the part of the outside of glof club head body 102.According to an aspect of the present disclosure, interchangeable quality loop 201 can be configured to the external engagement of the branch 114 in the bar bottom and divide 114 in the bar bottom of glof club head body 102.Further, according to aspects more of the present disclosure, the outside of bar bottom branch 114 can comprise the groove 114a that is used for quality of reception ring 201.For example, Fig. 4 is the illustrative examples according to this glof club head 102 and the quality loop 201 of aspects more of the present disclosure.As shown in Figure 4, the bar bottom that has with groove 114a according to some aspect glof club head bodies 102 of the disclosure divides 114.Groove 114a as shown in Figure 4 can be that 114 " otch " divided in the bar bottom.In other words, when club 100 was in homing position (for example as shown in Figure 1), groove 114a can divide 114 outer surface to being recessed on from bar bottom, thereby groove 114a divides 114 lowermost portion to sink with respect to the bar bottom.

According to aspects more of the present disclosure, groove 114a will meet or the shape of quality of match ring 201.For example, as shown in Figure 4, groove 114a can be circular or oval-shaped.As shown in Figure 4, quality loop 201 is configured to be engaged in groove 114a, and wherein the outside of quality loop 201 (on interior week and periphery) can contact through groove 114a and divide the ridge that forms in 114 in abutting connection with the bar bottom.Further, as shown in Figure 4, when quality loop 201 was engaged in groove 114a, the bar of glof club head body 102 bottom divided a part of 114 can extend through in the quality loop 201 opening in the heart.

Further, according to aspect quality loops 201 more of the present disclosure periphery extension of distaff bottom branch 114 at least in part.For example, as shown in Figure 4, quality loop 201 distaffs bottom divides the heel and the toe of 114 rear portions branch 114 along the bar bottom to extend.Further, as shown in Figure 4, be parallel to striking surface 108 with the relative that part of quality loop 201 of part that is engaged in branch 114 rear portions, bar bottom and extend from heel lateral to the toe side.Therefore, can see the quality loop 201 periphery extension of distaff bottom branch 114 by halves in this embodiment.Yet in other embodiments, 114 periphery extension is divided in quality loop 201 distaff fully bottom.For example, embodiment shown in Figure 5 has shown such embodiment, and wherein 114 periphery extension is divided in quality loop 201 distaff fully bottom.

According to aspects more of the present disclosure, quality loop 201 sizes can be set at and make its diameter cross glof club head 102 118 extensions from toe end part 116 to the heel end part basically.Yet diameter can be littler in other embodiments.For example, according to aspects more of the present disclosure, quality loop 201 can have at 2.5-12.5cm, 5.0-10.0cm, and the diameter between the 7.0-8.0cm.Further, according to aspects more of the present disclosure, quality loop 201 can have the round length between following size: 10-50cm, 15.0-25.0cm, 20.0-40.0cm, and 30.0-35.0cm.In addition, quality loop 201 can have at 0.25-2.0cm, 0.5-1.75cm, 0.75-1.5cm, and the thickness between the 1.0-1.25cm.Should notice that the thickness of quality loop 201 is needn't be always consistent.Instead, in certain embodiments,, the thickness of quality loop has different-thickness thereby can changing the different piece of quality loop 201.

The degree of depth of groove 114a can greater than, equal or slightly less than the thickness of quality loop 201.For example, the degree of depth of groove 114a can greater than, be equal to or less than 0.25-2.0cm, 0.5-1.75cm, 0.75-1.5cm, and 1.0-1.25cm.As stated, because the shape of groove 114a can meet the shape of quality loop 201, so the size of groove 114a can be similar to quality loop 201 aforesaid sizes.Therefore, be in concise and to the point purpose, omit further specific descriptions the size of groove 114a.

Construct the bar bottom with groove 114a divide 114 (this groove be used for quality of reception ring 201 and further gash depth is configured to equal or slightly less than quality loop 201 thickness) an advantage be; When quality loop 201 is bonded among the groove 114a; Quality loop will not extend beyond the outside that remainder is divided in the bar bottom, thereby the aerodynamics characteristics of club head body 102 are unaffected during the golfer swings.For example, the degree of depth of the thickness of quality loop 201 and groove 114a can be configured and make when quality loop 201 is engaged in groove 114a, and bar bottom divides 114 to be actually seamless and level and smooth.

Another advantage of this structure is the stability (for example as shown in Figure 1) that can not reduce at the golf clubs at homing position place.In other words, through in fact seamless assembling, glof club head body 102 will be just in time in place in not having the conventional club head body of interchangeable quality loop 201 like it.

Yet top description is not to have a mind to advise to use groove 114a.In fact, according to other aspects of the present disclosure, glof club head body 102 is not included in the bar bottom of glof club head body 102 and divides the groove in 114.For example, quality loop 201 can be engaged in the bar bottom of glof club head body 102 and divide 114, and said bar bottom is divided and do not comprised recess or the groove that is configured to quality of reception ring 201.In other words, quality loop 201 can directly be attached to the outside of the wall of bar bottom branch 114.

Should notice that quality loop 201 can have the different in width at the different piece place around ring.For example, as shown in Figure 5, according to aspects more of the present disclosure, the second portion that the first of quality loop 201 can specific mass ring 201 is wideer.Certainly, in other embodiments, the width of quality loop 201 can be uniform on quality loop 201.According to aspects more of the present disclosure, the part of quality loop 201 can have at 0.5-7.0cm, 1.0-5.0cm, 1.5-3.0cm, and the width between the 2.0-2.5cm.

The regular designated entities of golf, for example ((R&A) do not allow the some parts of golf clubs during the golf bout, to adjust in the imperial classic golf club of United States Golf Association (USGA) and St Andrews.Like USGA rules of golf, regular 4-2a.Therefore, do not violate such rule in order to ensure golf clubs, no matter how interchangeable quality loop 201 is engaged in bar the bottom divides 114, and interchangeable quality loop 201 should keep motionless through being locked into ad-hoc location during the golf bout.

According to some aspects of the disclosure, interchangeable quality loop 201 can be fixed to the bar bottom of glof club head body 102 in every way and divide 114.For example, the bar bottom divides 114 (for example groove 114a) and quality loop 201 can comprise corresponding hole, is used to receive threaded securing member.Therefore, threaded securing member (for example screw) can be inserted into, and this can be fixed to the bar bottom with interchangeable quality loop 201 and divide 114.Certainly, can use other mechanical fasteners, for example holding element, snap-fitted characteristic etc.).The bar bottom that in certain embodiments can tool using interchangeable quality loop 201 be attached to club head body 102 divides 114 or discharge from it.For example, above-mentioned structure needs screwdriver that screw is fastened in the hole of interchangeable quality loop 201 and bar bottom branch 114, to guarantee interchangeable quality loop 201 locks in place.It should be noted that further although some mechanical fasteners as above are described, this does not hint and must use mechanical fastener.On the contrary, as long as interchangeable quality loop 201 can be engaged with each other with glof club head 102 securely and can easily can be from discharging each other, such means are just because of covereding in the spirit of the present disclosure.

According to aspects more of the present disclosure, quality loop can have the counterweight characteristics different with the miscellaneous part of glof club head body 102.For example, quality loop 201 can have big proportion, density and weight.For example, quality loop 201 can have than the bigger proportion of other parts of glof club head 102 and more closely knit and heavier.For example, quality loop 201 can be at least in part basically or fully with high density and heavy made, for example various metals (for example plumbous, tungsten), alloy etc.According to some aspects of the disclosure, quality loop 201 can at least in part, basically or fully use polymer (for example relative flexibility and deformable polymer), plastics, elastomer, etc. process.According to some aspects of the disclosure, quality loop 201 can have the gram at 5.0-70,20-60 gram, or the quality between the 30-55 gram.

Further, according to aspects more of the present disclosure, quality loop 201 can have at least one first, and it is with different weighting charateristics with the second portion of quality loop 201.For example, quality loop 201 can comprise the bigger quality/weight of other parts of specific mass ring 201 in the particular portion office on the whole quality loop 201.For example, quality loop 201 can be included in the extra counterweight 202 of the specific location of whole quality loop 201.Counterweight 202 can have the bigger proportion of other parts of specific mass ring 201 and more closely knit and heavier.Therefore, counterweight 202 will further increase the weight of quality loop 201 in this part.In other words, quality loop 201 can be a loading (point loaded).Fig. 4 has shown the illustrative examples of the some loading of some aspects according to the present invention.As shown in Figure 4, quality loop 201 can comprise three counterweights 202 along 201 1 parts of quality loop.

According to aspects more of the present disclosure, quality loop 201 is interchangeable.In other words, quality loop 201 can be configured to from 102 disengagements of glof club head body and engage (for example relatively disengagement easily and joint once more) once more.In some cases, quality loop 201 can be changed by another quality loop 201, and this another quality loop can have different counterweight characteristics.For example, as stated, quality loop 201 can be a loading, wherein is provided with than the more weight of other parts at a part place of quality loop 201.Therefore, through therefore, the quality loop of the even weight of quality loop 201 usefulness through will putting loading is changed, and the center of gravity of glof club head body 102 can be shifted along specific direction.

In the embodiment shown in fig. 4, quality loop 201 is loadings, and counterweight 202 is positioned at the rear side of club head body 102.This structure of quality loop 201 makes that more multimass distributes towards the rear side of glof club head body 102.Such structure can help the golfer to obtain higher track or obtain ball flight.Therefore, tend to " low flight (duff) " (thereby promptly hit ball its along ground surface rather than pass air with higher lift angle and advance) the golfer can use such structure bond quality ring 201 so that compensation and alleviate the effect of " low flight ".For example; According to the disclosure, when quality loop 201 engages by this way, the rear side of the geometric center alignment glof club head body 102 that the center of gravity of club head can be advanced the from front to back 0.5cm at least that is shifted; And in some instances; At least being 1.25cm, is 2.0cm at least, or or even 2.5cm at least.Because the center of gravity of displacement, glof club head body 102 can be the golf that is impacted by glof club head higher track is provided.

Certainly, quality loop 201 also can be configured to have counterweight 202 in other parts.For example, quality loop 201 is configurable to be divided 114 o'clock in its bar bottom that is engaged in glof club head body 102 for making, extra counterweight 202 is positioned at the heel lateral of glof club head body 102.This structure of quality loop 201 makes that more multimass distributes towards the heel lateral of glof club head body 102.Compare with the toe that during swinging, allows the golfer to adjust the glof club head of club head better, such structure can help heel to be slowed down swinging, and this can cause less " right bent " (that is, more straight track).Therefore, the golfer who tends to " right bent " can be with such structure bond quality ring 201, so that compensation and alleviate the effect of right song.For example; According to the disclosure, when quality loop 201 engages by this way, the heel lateral of the geometric center alignment glof club head body 102 that the center of gravity of club head can be advanced the from front to back 0.5cm at least that is shifted; And in some instances; At least being 1.25cm, is 2.0cm at least, or or even 2.5cm at least.Because the center of gravity of displacement, glof club head body 102 can be the golf that is impacted by glof club head left bent deflected trajectory is provided.

On the contrary, quality loop 201 is configurable to be divided 114 o'clock in its bar bottom that is engaged in glof club head body 102 for making, extra counterweight 202 is positioned at the toe side of glof club head body 102.This structure of quality loop 201 makes that more multimass distributes towards the toe side of glof club head body 102.As stated; Compare with the heel that during swinging, allows the golfer to adjust the glof club head of golf club head better; Such structure can help during swinging, to make toe to slow down, and this can cause less " Draw (hook) " (that is, more straight track).Therefore, the golfer who tends to " Draw " can be with such structure bond quality ring 201, so that compensation and alleviate the effect of Draw.For example; According to the disclosure, when quality loop 201 engages by this way, the toe side of the geometric center alignment glof club head body 102 that the center of gravity of club head can be advanced the from front to back 0.5cm at least that is shifted; And in some instances; At least being 1.25cm, is 2.0cm at least, or or even 2.5cm at least.Because the center of gravity of displacement, glof club head body 102 can be the golf that is impacted by glof club head right bent (fade) deflected trajectory are provided.

Also have, quality loop 201 is configurable to be divided 114 o'clock in its bar bottom that is engaged in glof club head body 102 for making, extra counterweight 202 is orientated as and is in or near the striking surface of glof club head body 102.This construct more multimass distribute towards the striking surface side of glof club head body 102 111.Therefore, this structure can provide golf " to move ahead " or preceding impacting of rolling.For example, according to the disclosure, when quality loop 201 this modes engage; The center of gravity of the club head 0.5cm at least that can be shifted to the striking surface of glof club head body 102, and in some instances, be 1.25cm at least; At least be 2.0cm, or or even 2.5cm at least.Because the center of gravity of displacement, glof club head body 102 can provide and make golf " move ahead " or preceding impacting of rolling when impacting through glof club head.

According to aspects more of the present disclosure, quality loop 201 (with groove 114a alternatively) is configured so that quality loop 201 can be thrown off, rotation (for example along clockwise direction or counterclockwise) is engaged to different orientation again.Under a situation of load mass ring 201, weight can be displaced to the opposite side of club head body 102, so that redistribute the quality and weight of glof club head body 102.For example; Change into the club (wherein counterweight 202 is in the toe side of club head body) with right bent deflection for the club head body (wherein counterweight 202 is positioned at heel lateral (and therefore glof club head body 102 has left bent deflection)) that will have a load mass ring 201, the golfer only needs drop-outs load mass ring 201 and lets a load mass ring 201 rotate (for example the gyrating mass ring is 180 °) and it is engaged with club head body 102 again.In other words, quality loop 201 can be thrown off from first orientation, thereby wherein quality loop 201 first that is engaged in glof club head body 102 quality loops is in (it comprises counterweight 202) heel lateral of glof club head body 102.Quality loop 201 can rotate to second orientation from first orientation subsequently; In case wherein quality loop 201 engages with glof club head body 102 in second orientation again; Then when quality loop 201 rotations, the first of quality loop 201 (it is in the heel lateral and is in first orientation) will be in the toe side.Quality loop 201 will engage with groove 114a in second orientation subsequently again.

Certainly it should be noted that interchangeable quality loop 201 needs not to be a loading, and instead, counterweight can evenly distribute around quality loop 201.Therefore, interchangeable quality loop 201 can be substituted by another quality loop 201, although this another quality loop be still and have different counterweight characteristics uniformly (for example its equably gentlier or heavier).

Above-mentioned characteristic allows the quality and weight of glof club head body 102 easily to change.Therefore, should understand quality and the counterweight characteristics that interchangeable quality loop 201 can be used for regulating subtly based on golfer's special tendency glof club head body 102.Therefore, club head body 102 can easily customize and mate specific golfers and its specific tendency that swings.

No matter whether quality loop 201 is a loading or even distribution of weight, the bar bottom that is engaged in glof club head body 102 at quality loop 201 was divided 114 o'clock, and the center of gravity of glof club head body 102 reduces.For example, according to the disclosure, when quality loop 201 this modes are located; The center of gravity of glof club head body 102 0.5cm at least that can at the bottom of the bar of glof club head body 102, be shifted; Be 1.25cm at least in some instances, 2.0cm at least, or even 2.5cm at least.Because the center of gravity of displacement, glof club head body 102 can be the golf that is impacted by glof club head higher track is provided.

Further, as stated, the bar bottom that quality loop 201 is positioned at glof club head body 102 divides this structure on 114 the more multimass of glof club head body 102 to be redistributed the edge of glof club head body 102.Therefore, the MOI of glof club head body 102 increases.The MOI that increases is the resistance that provides bigger that reverses during the off-centre with golf of glof club head body 102 impacts, and therefore the bigger tolerance that mistake is impacted is provided.

Therefore; The center of gravity that the above-mentioned structure on 114 not only reduces glof club head body 102 (ball that this provides higher track and auxiliary golfer's acquisition in air, to advance) is divided in the bar bottom that quality loop 201 is bonded on glof club head body 102; And the quality of above-mentioned structure redistribution glof club head body 102, thereby the MOI of glof club head body 102 increases and glof club head body 102 can tolerate that more mistake impacts.
