Abstract
The present invention relates to an exemplary golf club head having additional discretionary mass which can be realized by utilizing light-weight materials, a favorable average height, and/or one or more articulation points. By using a preferred break length, the additional discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial moment properties. In one example, the center of gravity can be positioned to substantially align the sweet spot with the face center of the club head.
Description
Background technology
The mass range that the wood golf club head usually has about 150 to 250g.The part of this quality has been kept the structural intergrity of caput.Residual mass is called " freedom " quality, can divide to be equipped with mass property and/or the inertia characteristics of improving caput tactfully.
Increase the known method of available free quality, for example reduce the caput wall thickness, produced minimum benefit.Therefore, the ability that provides improved performance of modern wooden caput is partly with the amount restriction by the obtainable free quality of conventional method.
Usually, golfer's trend naturally is to impact golf around the excellent face center of caput.In most of wooden rods, excellent face center is when square stance the point of largest face resilience to take place on excellent face, and also is known as recovery coefficient (COR) " focus ".Though the batting at COR " focus " produces big stick-means of intimidation face resilience, but also may produce coarse hitting, because in the caput of routine, " dessert " (" dessert " be caput center of gravity (CG) in the lip-deep rectangular projection of impacting of caput, and be the point that caput rotation or engagement effect do not take place on the excellent face) usually be positioned at COR " focus " top.Therefore, for the wooden bat of routine, only single performance variable, promptly with bat on every side at COR " focus " relevant big stick-means of intimidation face resilience or with bat the relevant accuracy that hits on every side at " dessert ", can hit increase to arbitrary golf.
Usually, make the engagement effect expansion of caput rotation and caput, thereby cause the loss of flying distance (carry distance) and precision in the pericentral batting of excellent face of the wooden bat of routine.
Hit precision and distance also is subjected to the influence of CG with respect to the degree of depth of excellent face.In conventional golf club (driver), CG typically is positioned near the excellent face.Therefore shallow CG position has reduced bar to the dynamic bending that aligns with CG, has reduced the useful inclination (loft) of caput and the sealing of rod face with ball impact the time.In addition, shallow CG has reduced the radius of turn of excellent face when off-center hits, has therefore reduced hitting precision.

In addition, can utilize the increase of free quality to pass through along the reference path P on a plurality of top portion 2050 (Figure 11 C) at caput
1... P
nOne or more at least one artis 172 (Figure 13 A) that provide realize.By utilizing the favourable number of artis 172, the crown shape of the distribution of weight that can realize being of value to favourable.For example, as illustrating in Figure 13 A, concave surface 1015 can two artis 172 be formed in the top portion 2050 of caput 101 by for example providing.Such caput structure allows quality to be redistributed to more favourable position in the caput from the top portion of caput.Therefore, quality can be reallocated, and for example improves the inertial properties of caput and/or the position of center of gravity CG.This can allow more fault-tolerant caput and cause improved precision and the distance of hitting.
According to one or more aspects of the present invention, when for example low as far as possible and when dark, the center of gravity of caput can more advantageously be located by the position of additional free quality in typical caput 101 that utilizes local non-metallic component, favourable average height and/or one or more artis to obtain.Can have the form of one or more weight element or liner as the additional free quality that above disclosure obtained, they can have at for example combination weight between the extremely about 80g of about 5g.
As shown in Figure 10 A, it is limited that for example the conventional caput of caput 143 carries aspect the low and dark free quality potential in base, partly is because their base portion, and for example base portion 141 usually raises with respect to ground 108.Refer again to Figure 10 A, according to one or more aspects of the present invention, golf club head 101 comprises the base portion 139 that is configured with breaking length 142, compares with the corresponding breaking length 142a of the conventional caput 143 with similar volume, and this breaking length 142 is extended.Compare with the conventional caput of for example caput 143, being configured in of the novelty of base portion 139 allowed the lower and darker placement of free quality in caput 101 of the present invention in its a plurality of examples, as obvious by increasing breaking length 142.
Therefore, caput 101 can have the breaking length 142 between about 50mm and the about 110mm at vertical range 144 places between distance ground 108 about 1mm and the about 15mm.Preferably, can be in the vertical range 144 place's breaking lengths 142 between distance ground 108 about 5mm and the about 10mm approximately between 90mm and the about 150mm, more preferably approximately between 96mm and the about 140mm, again more preferably approximately between 100mm and the about 140mm, again more preferably at about 110mm with approximately between the 140mm, and most preferably at about 120mm with approximately between the 140mm.According to one or more aspects of the present invention, breaking length 142 allows lower and the depths of free quality in caput 143 placed, thereby the improvement of position of centre of gravity is provided.
Also shown in Fig. 4 A, the breaking length of the increase relevant with one or more aspects according to the present invention structure base portion 139 can allow free quality is positioned at abundant lowers in the caput 101, being to align in excellent face center 112 dessert 134 with COR " focus " substantially.By lowering the center of gravity CG and dessert 134 alignd with COR " focus " 112, the benefit of two performance variable, the precision that hits distance and the relevant increase with " dessert " 134 of promptly relevant with COR " focus " 112 increase can realize simultaneously.
The breaking length of the increase relevant with one or more aspects according to the present invention structure base portion 139 also can allow center of gravity deeper positioning in caput.With reference to figure 3A, the degree of depth of center of gravity is the shortest horizontal range between center of gravity CG and the vertical plane 126 that comprises hosel center 122, for example distance 124.The degree of depth that increases center of gravity CG has improved bar to the dynamic bending that aligns with center of gravity, with inclination caput with ball impact the time and with preferably " edge-on " sealing of excellent face.Therefore, service condition and hit precision and can improve.
