In a second embodiment, glof club head can comprise body and a plurality of ribs that stretch out from the rib surface of body.Body can comprise heel end, toe-end, bizet, bottom, front surface and rear surface.A plurality of ribs can be usually straight and disjoint, and/or can comprise near the first rib of the heel end of body with near the second rib of the toe-end of body.A plurality of ribs can also arrange with substantially emanant pattern, to form similar fan-shaped shape between the first and second ribs.

In the 3rd embodiment, method can comprise that (a) forms the body of the glof club head with heel end, toe-end, bottom, front surface and rear surface, and (b) forms a plurality of ribs that stretch out from the rib surface of body.A plurality of ribs can comprise the first rib with first longitudinal axis that extends through common ground, have the second rib of the second longitudinal axis that extends through common ground and have the 3rd rib of the 3rd longitudinal axis that extends through common ground.Wherein common ground can be positioned at outside the body.

Other embodiment and embodiment are further disclosed herein.Can in accompanying drawing, claims or this specification, find these embodiment and embodiment.

With reference to Fig. 1-3, golf clubs 10 comprises club head 12, joint chair (hosel) 14 and shaft 16.Club head 12 is comprised of ducted body 18, and ducted body 18 is usually by stainless steel, titanium or have the higher coefficient of rigidity and the other materials of higher strength-to-weight ratio is made.Ducted body 18 comprises antetheca or surface 20, and it is suitable for clashing into golf.Ducted body 18 further comprises roof or bizet 22, diapire or bottom 24 and the sidewall or the skirt section 26 that surface 20 are connected to bizet 22 and bottom 24.Club head 12 also comprises heel end 30 and toe-end 32.Skirt section 26 surrounds the club head 12 between heel end 30 and the toe-end 32, thereby forms rear wall 28.Glof club head 12 can be the glof club head for service bar, Fairway Woods or mixed pole.

Bizet 22 comprises the thin-wall construction of a part that preferably is cast into ducted body 18.Bizet 22 is preferably has the relatively thin titanium that thickness is 0.076 ± 0.013cm.Adopt a plurality of lower surfaces 36 from bizet 22 to strengthen bizet 22 to the rib 34 of downward-extension.The second end that each rib 34 separates with it but the first end that separates with it extends to contiguous rear wall 28 from adjacent front wall 20.Interval between the rib 34 is large at its first end at its second end ratio, and preferred large 20%.Adjacent rib 34 departs from least 5 ° angle towards its second end from its first end.That rib 34 comprises is narrow, elongation, be generally straight, metal, shock wave distributed elements, and these parts have the height of 0.051 ± 0.013cm and the width of 0.178 ± 0.013cm.When observing with the form in cross section, rib 34 is generally to lower convexity, and is fused to smoothly the lower surface 36 of bizet 22.Should be appreciated that bizet 22 is not included in rib laterally extending between the rib 34.

The lower surface 36 of bizet 22 has forward direction part and backward part, wherein forward direction partly and backward part by usually be parallel to antetheca 20, the center line at half place of distance limits between the most front point on the antetheca 20 and the rearmost point on the rear wall 28.The first end of rib 34 ends at the forward direction part of bizet 22, and the second end of rib 34 ends at the backward part of bizet 22.

Can be clear that from Fig. 2 rib 34 is lined up array according to following pattern: the longitudinal axis 38 of rib 34, and intersects at this point to external radiation at point 40 places in the space that is arranged in antetheca 20 the place aheads.Point 40 is preferably placed in 1/3 width (W/3) of centre of antetheca 20, and preferably substantially is positioned at the front of the center line of antetheca 20.Should be noted that because club head 12 is said three-dimensional body, such as used herein, therefore when in the plane at Fig. 2 it being observed, put 40 finger a single points.Alternatively, 40 can be considered to the vertical curve that the crossover track by the vertical plane of the center line by rib 34 consists of.

Rib 34 extends to the second place adjacent with rear wall 28 from the primary importance adjacent with the intersection 42 of the rear surface 44 of antetheca 20 and the lower surface 36 of bizet 22.In schematic embodiment, in the rib 34 at least half and preferably all rib 34 all begin to extend and cross the mid point (L/2) of club head 12 from antetheca 20, but rib 34 is by any horizontal rib interconnection.Therefore, the action of each rib 34 is independent of other ribs 34 of the thinner part interconnection of the bizet 22 that only passes through betwixt insertion.Point 40 preferably is no more than L/2 in the place ahead of antetheca 20.So just, formed the pattern that is included in ten ribs 34 of (angular divergence that perhaps has 4 to 8 degree between the adjacent rib 34 preferably, is about 6 degree) in the string that is approximately 60 degree angles.

The surprising result of this configuration of rib 34 is, compare with unstrengthened crown area, although 0.051 centimetre is high, the array of 0.178 centimetre of wide vertical ribs has been only so that maximum stress has reduced 9%, according to the present invention with the rib 34 of the fan-shaped pattern arrangement of radiation so that the maximum stress of crown area has almost reduced 36%.Although do not wish to be confined to any specific operating principle, it is believed that owing to surface 20 outwards anisotropically extensions from the point of impingement own are out of shape, therefore similarly to transfer loads to crown area from the point of impingement to extraradial mode heterogeneous.Therefore, the rib 34 that has near outward extending radiation pattern point of impingement bizet 22 of stayed surface 20 more effectively collision process.

Except the straight linear rib with substantially invariable width and height shown in Fig. 1-3, also can adopt the embodiment of the substituting glof club head with rib.For example, rib can be that height and/or the width of crooked or rib can change.

For example, Fig. 4 shows another embodiment of glof club head.Fig. 5 shows the cutaway view of the embodiment of the Fig. 4 that obtains at the line place that is designated as " 5 ".Glof club head 412(Fig. 4) comprise having antetheca 420(Fig. 4) ducted body 418(Fig. 4), bizet 422(Fig. 4), bottom 524(Fig. 5), connect sidewall 526(Fig. 5 of bizet 422 and bottom 524), heel end 430(Fig. 4), toe-end 432(Fig. 4) with rear side 428(Fig. 4 relative with antetheca 420).In addition, glof club head 412 can also comprise the rib 440(Fig. 4 from the lower surface of bizet 422 to downward-extension).In the embodiment of embodiment shown in Figure 4, rib 440 comprises the first end with adjacent front wall 420 and the rib 441,442,443,444,445 and 446 that is close to the second end of rear side 428.
