Description

The golf club face of portion's pressurization within it

1. technical field:

The present invention relates generally to the glof club head and the iron golf bar head of a kind of metal " timber ", especially relate to a kind of glof club head and a kind of optional method and employed instrument thereof that is used for changing its pressurization with double wall panel of portion's pressurization within it.

2. background technology:

In order to improve golfer's achievement, the golf clubs producer has made multiple design for golf clubs.Use in above-mentioned " timber " with flying distance that increases ball and the feel that improves club as the different materials that will contain multiple metal.Or adopted the scheme that increases the weight of miscellaneous, and comprise the perimeter weighting scheme, optimize the center of gravity and the moment of inertia of club head.Or adopt the club head of super large so that provide large-scale sweet spot on the face impacting of ball.But the weight that is used for golf clubs specialty or PGA's approval is subjected to Golf Association and strictly controls.Therefore, special in excessive club head, can not consider that its weight or its can pass this whole super large club head in panel inside or peripheral metal thickness to admit of suitable thickness.

The most important factor of perhaps accomplishing fluently golf is the face that ball impacts or the position of the striking point on the ball on the panel.The ball that impacts with the sweet spot of the center of panel or panel is usually than with flying farther more directly near panel bottom or toe or being higher or lower than the ball that the sweet spot place impacts.For this reason, the distribution of inner or peripheral weight of panel or quality becomes important extraordinarily when impacting golf in order to remedy that an off-centre impacts and in the position away from sweet spot.Therefore, no matter manage during glof club head to make in design be to carry out in sweet spot that target impacts or impacting of departing from objectives outside sweet spot can both reach maximizing efficiency to club designer.

Another key factor of accomplishing fluently golf is the coefficient of resilience of the striking surface of golf club face (" COR ").For a given club head speed, the increase of COR will strengthen dynamics that passes to golf and the flying distance that therefore increases ball.But high COR also may cause hitting the ball at sweet spot center than easier the flying to outside the line of ball with the club head of hanging down COR.Therefore, expert or professional athlete can use usually and can be harmonious better and utilize its advantage with high COR club head, and general player may be just when they can realize the advantage of high COR club head once in a while at the sweet spot square stance, the club head of remaining time to high COR may be disadvantageous.

Owing to can control departing from of sweet spot preferably, thus the club head that is combined with high COR or adjustable COR for be specialty or general golfer is beneficial.

Fig. 5 is the partial view according to another alternative embodiment of glof club head of the present invention.

The specific embodiment

Fig. 1-5 expression is according to the various views and the embodiment of the double wall panel of glof club head 10 of the present invention.Glof club head 10 is made by a kind of metal wood, though it also can be fabricated from iron from the principle.

Fig. 1 represents to pass through from front to back the side section of glof club head 10.Glof club head 10 comprises and impacts wall 12 and rear wall 14 and by chamber 16 that they limited.Glof club head 10 also comprises top 18 and base plate 20.Base plate 20 also can comprise rear portion 22.Impacting wall 12, rear wall 14 and base plate 20 preferably is made of metal.Cover layer 18 may be to be made of metal or to be made by plastics, graphite or composite, as the application number at pending trial is US10/766,220, the applying date be discuss as an example in the patent application on January 28th, 2004 like that, it is drawn herein and is reference.

Impact wall 12 and can make identical thickness with rear wall 14, still, preferably rear wall 14 is thicker, thereby its pliability is not as antetheca 12.The thickness that impacts wall 12 and rear wall 14 is preferably in 0.1mm arrives the scope of 6.0mm.This thickness also can change from top to bottom and can be constant from root edge portion to rim portion.Similarly, the cross sectional dimensions in chamber 16 can constantly also can change to rim portion from top to bottom and/or from root edge portion.Usually, the cross sectional dimensions in chamber is all in 0.1mm arrives the scope of 6.0mm.

Shown in the cutaway view of Fig. 1, bar head 10 have thickness identical impact wall 12 and rear wall 14, its thickness all at 1.5mm in the scope of 3mm.And chamber 16 has roughly the same cross sectional dimensions at 1.5mm in the scope of 3mm.Owing to taked this structure, for impacting before inwall 12 provides direct actual the enhancing, panel 12 may be towards rear wall 14 deflections until fully through the scope in chamber 16 at rear wall 14.The size dimension that impacts wall 12 and chamber 16 can be selected, and can not fall back on rear wall 14 deflection backward fully so that impact wall 12 when do not pressurizeed in chamber 16 in normal operating range.

Fig. 2 and 3 is the part sectioned views that are similar to Fig. 1, and it is illustrated in the deflection that impacts wall 12 when impacting golf 30.Fig. 2 represents when the deflection near effective striking point on the ball of the center that impacts wall 12 time of 30 dozens of golf.At this moment, impact the place deflection backward that wall is contacting with golf 30.But when pressurized back, chamber 16 and rear wall 14 had enough resistance deformed configurations rigidity, the pressurization in the inside that impacts cavity of resorption 16 of golf 30 may make the outwards deflection of periphery that impacts wall.When golf clubs 10 and golf 30 were pushed ahead after impacting at first, impacting wall 12 will be from original deflection resilience and the energy that will absorb by deflection to golf 30.In impacting process, when golf clubs 10 impacted golf 30, golf 30 was oval, and the cyclic process that will experience distortion and recover.

Fig. 3 is illustrated in the deflection situation that impacts wall 12 when impacting golf 30 on the position of departing from effective striking point on the ball.In Fig. 3, impact point is positioned at the top of the effective striking point on the ball that impacts wall 12.Because the structural drag of approaching more its deflection of edge that impacts wall 12 is big more and because cambered surface is crooked backward, near described edge, therefore, inwardly or be less than the deflection of the downside that impacts wall 12 that is positioned at golf 30 belows near the deflection on the top that impacts wall 12 at edge.Off-centre of these difference recoverable golf 30 impact, and similarly are at the effective flight path of the ball of striking point on the ball square stance thereby provided corrected.Above-mentioned correction makes the scope of effective striking point on the ball enlarge towards the direction that impacts inwall 12 edges.Thereby also can produce similar effect when shifting to the rim portion that impacts wall 12 or root edge portion when impacting.

16 in chamber is formed in the process that fixedly impacts wall 12 and rear wall 14, for example will hit wall 12 and rear wall 14 is fixed by welding.In the said fixing process, chamber 16 may under atmospheric pressure, also may at parital vacuum or add to depress and seals.The annular seal space 16 easier coefficients of resilience that cause the deflection that impacts inwall 12 and reduced golf clubs under parital vacuum.By comparison, will reduce the deflection that impacts inwall 12 and increase the golf clubs coefficient of resilience in pressurization lower seal chamber.

In addition, the present invention considers a valve is added in the glof club head 10 to allow the user selectively annular seal space 16 to be pressurizeed.As shown in Figure 4, valve 40 crosses the rim portion 22 that impacts wall 12 and install to glof club head 10.Above-mentioned valve is designed to connect a pump 42, or adds pressure cylinder 44 to be used to chamber 16 pressurizations.Preferably, chamber 16 usefulness compressible gases or air pressurize.But chamber 16 also can be full of by incompressible fluid.

Fig. 5 represents a kind of optional structure of the present invention, and wherein, valve 50 is added in root edge portion 24 1 sides (for the club of the right hand) of bar head 10, and is connected on the position of rear wall 14 and the bottom of pore 46 intersecting.This structure makes pressure to be introduced into or to allow pump is located in the golf club shaft by golf club shaft.

The valve 40 of Figure 4 and 5 is preferably check valve, so that air or other fluid media (medium) are pumped in the chamber 16.But if necessary, valve 40 also can be set to the decompression valve for chamber 16.

Bar head 10 can be in conjunction with combination cover, and it is designed to be installs closely and be harmonious with the root edge portion 24 of top board 18, rim portion 22 and base plate 20.The combinations thereof lid utilizes a kind of suitable binding material, and for example glue, epoxy resin or solvent-borne type adherent are glued on the metal part 12.

Pore 46 is in the middle vacancy of glof club head inside and in the root edge portion 24 of base plate 20 and the junction between the rear wall 14, and it is made into and is located in the bar head 10 to hold golf club shaft.The center of the center of gravity of the preferred and bar head 10 of pore 46 is a straight line or skew.Described club head 10 is suitable for the user that the right hand is held bar, and for the user that left hand is held bar, club head then is the design of a mirror image symmetry.
