The present invention relates to a kind of replaceable shaft system, it is used for the shaft of golf clubs is connected to the bar head.Can adopt this system that all kinds shaft of customization is assembled to the bar head and/or provides adjustable between shaft and bar head.Several specific embodiment of the present invention is as mentioned below.
Golf clubs with replaceable shaft of the present invention system 10 generally includes shaft 12, shaft cover 14, bar head 16 and securing member 18.In the process of assembling, the club assembler can utilize replaceable shaft system 10 to change shaft 12 and 16 combinations of bar head repeatedly.This system makes the optional quantity of wieldy Assembly part maximize.In one embodiment, after the combination of having selected desirable shaft 12 and bar head 16, replaceable shaft system 10 can be by for good and all fixing to prevent the ordinary consumer dismounting.Perhaps, replaceable shaft system 10 can constitute and can make the consumer operate this connection, to replace shaft 12 or bar head 16 and/or provide adjustable between shaft 12 and bar head 16.
As shown in the figure, replaceable shaft of the present invention system is attached in a kind of golf clubs of actuator type.Yet, be understood that replaceable shaft of the present invention system can be attached in the golf clubs of any kind.For example, replaceable shaft system can be attached in the golf clubs of push rod, wedge shape part, irony part, mixed type and/or meadow woody type.
Referring to Fig. 1-5, replaceable shaft system 10 is connected to shaft 12 on the bar head 16, thereby different shaft 12 can be connected on the different bar heads 16 selectively by the hosel socket.Replaceable shaft system 10 generally includes and joins on the shaft 12 and be contained in shafts cover 14 in the hosel 20 of bar head 16 and the securing member 18 that shaft cover 14 is couple to releasedly bar head 16 at least in part.
In the replaceable shaft system 10 that assembles, the end portion 34 of shaft 12 is contained in the shaft trepanning 36 of shaft cover 14, and is attached fixedly to this.Can use any fixing means that shaft 12 fixedly is attached in the shaft cover 14.For example, for example welding of spendable attachment method, ultrasonic bonding, solder brazing, solder, bonding and mechanical fasteners connection etc.For example the adhesive of epoxy resin or other similar material all can be used for shaft 12 and shaft cover 14 fastening reliably.Preferably end portion 34 is bonded in the shaft trepanning 36 with for example adhesive of epoxy resin.Perhaps, the structure of shaft cover, for example screw threads for fastening structure and the align structures part that can be used as one is incorporated in the structure of shaft, and for example by molded together, concrete content is introduced below with reference to Figure 25-30.
With selected orientation shaft cover 14 is inserted in the hosels 20, to guarantee that when the replaceable shaft of the assembling system, the align structures and the align structures on the hosel 20 that are included on the shaft cover 14 engage.The orientation of align structures provides desirable relative position for shaft 12 and bar head 16.In addition, the joint of align structures provides the prevention revolving property, and this characteristic prevents that the longitudinal axis around hosel 20 rotates relatively between shaft cover 14 and the hosel 20.
In this embodiment, the near-end 28 of hosel 20 is arranged on from bar head 16 outside positions away from top 25, and comprises at least one hosel align structures, and this align structures extends through at least a portion sidewall of hosel 20.In the golf clubs that assembles, the hosel align structures is for providing at least one discrete orientation of aiming between bar head 16 and the shaft 12.In this embodiment, hosel 20 included align structures are the form of a pair of recess 32, and each recess 32 extends through the sidewall of the hosel 20 of located adjacent proximal end 28, and just, each recess 32 extends to the outer surface of the near-end 28 of hosel 20 from shaft trepanning 30.
Should be understood that the hosel align structures does not need to extend through fully the sidewall of hosel, can only extend through the part of sidewall, shown in the embodiment of Fig. 6.Especially, the proximal part 22 of hosel 21 can comprise the recess 33 that only extends by hosel 21 a part of sidewalls.For example, the recess 33 of present embodiment comprises the trapezoidal section that is generally that is similar to described in the foregoing description, yet, recess 33 radially extend through from shaft trepanning 29 hosel 21 proximal part 22 a part of sidewall but do not intersect with the outer pole face of hosel 21.When the user wished to hide align structures, this embodiment was preferred.
When the replaceable shaft of assembling system 10, the shape of recess 32 and tang 42 complementations is guaranteed reliably assembling between shaft cover 14 and the hosel 20.Especially, when shaft cover 14 was inserted in the shaft trepanning 30 of hosel 20, the tapered side edges of tang 42 was forcibly against the tapered sidewalls of recess 32, so that firm assembling to be provided, guarantee that shaft cover 14 can be firm with respect to hosel 20 and location repeatably.The taper pole face also can prevent rotatablely moving between the shaft cover 14 that caused by manufacturing tolerance or wearing and tearing and the hosel 20.Perhaps, hosel and shaft cover align structures can have curved edge and the sidewall that engages between erecting stage, so that same firm assembling to be provided.
In this embodiment, the external diameter of main body 38 is less than the external diameter of lining 40 ends, so that make the interface between main body 38 and the lining 40 form shoulder 46.In the process of assembling, the main part 38 of shaft cover is inserted in the shaft trepanning 30, is positioned at the position of the top of contiguous hosel 20 up to shoulder 46.(for example, tang 42 and recess 32) size, tapering and/or curvature is preferred, only has a spot of gap so that make when the assembling golf clubs between shoulder 46 and the hosel 20 for hosel and shaft cover align structures.In addition, with regard to this embodiment, select the size of tang 42 and recess 32 and tapering so as to make the end surface of tang 42 and the end surface of recess 32 between only have little clearance.This gap allows the relative position control easily by the size of controlling each self-alignment structure between shaft cover 14 and the hosel 20.Preferably, in the golf clubs that assembles, the gap value between shoulder 46 and the hosel 20 visually is imperceptible, perhaps is not conspicuous at least.For example, gap value can be in the scope of 0.005-0.030 inch.
Also can to shaft overlap 14 and/or hosel 20 apply or surface treatment, to prevent to corrode and/or a kind of aesthetic appearance of wanting to be provided and/or other architectural characteristic is provided.For example, in an embodiment, the shaft of use cover 14 is made by first metal material, aluminium for example, hosel 20 is made by second metal material, titanium for example, but like this shaft cover 14 with regard to anodization to prevent electrochemical corrosion.Further example is, available nickel coated non-metallic shaft cover 14 is with outward appearance that metal structure is provided and/or additional strength is provided.Can select to apply provides any characteristic of wanting, and for example, can be the coat of metal with nanocrystalline structure, for example nickel alloy in order to improve the intensity coating.
With securing member 18 shaft cover 14 is fastened firmly to bar head 16, in case stopping bar body cover 14 breaks away from from shaft trepanning 30.Securing member 18 is mainly used to prevent shaft cover 14 and bar head 16 relative motion on the longitudinal axis that is parallel to hosel 20 by introducing axial compressive force.Securing member 18 can be to limit any kind securing member that relatively moves between shaft cover 14 and the hosel 20.For example, as shown in this embodiment, securing member 18 is longilineal machanical fasteners, for example is to be bonded on shaft to overlap mechanical screw in 14 screwed holes.The size of securing member 18 and shaft cover 14 provides enough reaches, thereby resists the axial force that produces in the replaceable shaft system 10.In an exemplary embodiment, the size of securing member 18 and shaft cover 14 can provide 1/4 inch threaded engagement length.In addition, increase screw strength if desired and can use threaded insert.For example, the threaded insert (Newark, the registration mark of DE company is Emhart) of for example Heli-coil can be installed in the shaft cover 14.
As shown in Figure 3, hosel 20 only partly extends through bar head 16.Provide independent securing member perforation 50 extend into from the position of approaching bottom 26 bar head 16 and roughly with hosel 20 coaxial alignments.The near-end of fastener hole 50 is stopping near flange 54 places.Flange 54 roughly be annular and provide bearing-surface for the head of securing member 18.The bar of securing member 18 extends through flange 54, crosses gap 52 between securing member perforation 50 and hosel 20, engages by flange 31 and with the flange 44 of shaft cover 14.
Between erecting stage, when securing member 18 was tightened up, shaft cover 14 was inserted in the hosel 20.Simultaneously, the tang 42 of shaft cover 14 is inserted in the recess 32 of hosel 20, and the tapered side edges of tang 42 is forcibly against the tapered sidewalls of recess 32.When the taper interface between tang 42 and the recess 32 can be guaranteed in securing member 18 is fastened to shaft cover 14, assembling between shaft cover 14 and the hosel 20 can become more firm gradually, but and shaft cover 14 move to positions predetermined and resetting in the hosel 20.
As previously mentioned, the hosel align structures is positioned the position of the near-end 28 of contiguous hosel 20, and extends through at least a portion sidewall of hosel 20.The hosel align structures is positioned at the manufacture process that contiguous hosel 20 near-ends 28 places can simplify hosel align structures and bar head 16 greatly, because should the zone approaching easily.Especially, the align structures with precision tolerance can only be incorporated in the hosel 20 by simple mechanical processing steps and the common instrument of use.For example, a kind ofly be generally the trapezoidal hosel align structures that whole hosel 20 sidewalls extend that passes through, for example recess 32, and it can use a tapering point milling cutter to carry out machining, and this end mill(ing) cutter is the near-end 28 by casting bar head 16 radially.Ding Wei result is like this, and the hosel align structures with accurate controlling dimension just can easily be made any shape of wanting by simple tools processing and step.
Align structures can be positioned on any position on shaft cover 14 and hosel 20 circumference.Preferably, a pair of align structures becomes about 180 ° of branches to be arranged (that is, align structures is radially relative) around main body 38 with hosel 20 circumference, pole face 24 location of the contiguous bar head 16 of one of them align structures.This orientation makes and club to be placed on sight line that homing position and edge be roughly parallel to the longitudinal axis of shaft 12 when seeing club as the user that align structures is sightless for the user.When the sight line that is approximately perpendicular to pole face 24 by the edge saw that bar head 16 is adjusted, this orientation also can make the user easily see align structures.
As supplementary features, also can provide locking mechanism from shaft cover 14, to break away to prevent securing member 18.Any locking mechanism all can use.For example, lock washer can be arranged between the head and contiguous bearing-surface of securing member 18.As further replacement, a kind of locking screw thread design, for example (registration mark is the Madison Heights of Detroit Tool Industries Corporation to the locking internal thread of Spiralock, MI) can be used in the screwed hole 48 of flange 44.As further replacing, with the thread lock material, for example Loctite thread lock fluid sealant (trade mark is PA, the Henkel company of Gulph factory) is applied in securing member 18 or the screwed hole 48.Further, can to provide a kind of for example be the locking piece of inserted sheet lock to securing member 18.In addition, with adhesives, for example epoxy resin is coated in the interface place of the head and the bar head 16 of the securing member 18 that assembles.
As feature further, when securing member 18 does not engage with shaft cover 14, can adopt keeper 56 that securing member 18 is remained in the bar head 16.When replacing shaft 12, wish securing member 18 is remained in the bar head 16 in case misplace.Keeper 56 is bonded on the shank and the location of securing member 18, thereby flange is inserted between the head of keeper 56 and securing member 18.The size of setting keeper 56 makes it can not pass through the through hole of each flange.Baffle ring 56 can be a clip, and its mode with friction joins the shank of securing member 18 of flange 31 location of contiguous hosel 20 to, thereby flange 31 is inserted between the head of baffle ring 56 and securing member 18.
Referring to the embodiment of Fig. 7 and 8, many shaft covers will describing can be used to replace the shaft cover 14 in the replaceable shaft system described in the preamble.The configuration that this many embodiment provided (conifiguration) is compared with single Jian machining or molded shaft cover, and it allows to adopt selectable machining process.In addition, it is for comprising that multiple material provides additional selection, the advantage that this single shaft cover can provide weight and/or make in single shaft cover.In one embodiment, shaft cover 63 comprises many structures, and it comprises main body 65, a pair of align structures (for example tang 67) and lining 69.In this embodiment, tang 67 is one with lining 69, but main body 65 is independent elements.
Referring to Fig. 8, describe shaft and overlap another optional embodiment.Shaft cover 64 comprises main body 66, a pair of align structures (for example tang 68) and lining 70.Tang 68 is one with main body 66, and lining 70 separates with main body 66 with tang 68.Main body 66 is normally columned, and comprises near-end, and in the time of on being assemblied in shaft, this near-end is positioned at the end of contiguous lining 70.The near-end that tang 68 is adjacent to main body 66 laterally stretches out from main body 66.
Available any material is made main body 66 and lining 70, and they can be made of identical or different material.For example, main body 66 can be formed by metal material machining, for example aluminium.Lining 70 can be by nonmetallic materials molded or machining form nylon for example.Using different materials is the weight that is used for reducing whole metal shaft cover, and enough architecture quality and bonding surface areas also will be provided simultaneously.In addition, can select the various materials that desirable aesthetic characteristic can be provided.
If desired, the main body of shaft cover can further comprise the feature of weight reduction among any embodiment.For example, as shown in Figure 8, dash area 72 can comprise groove, pit, through hole or reduce any further feature of the material volume that constitutes main body 66.As long as can provide enough surface areas to be used for shaft is fully engaged with the shaft cover, just can reduce the material volume of any hope part on the shaft cover main body.
A further embodiment of shaft cover as shown in Figure 9.Be similar to hereinbefore described embodiment, shaft cover 74 comprises main body 76, lining 78 and from main body 76 horizontal outward extending tang 80.With shaft cover 74 is that solid memder is an example, and it forms by nonmetallic materials are molded, for example, and nylon, fiber-reinforced polymer or Merlon.Because this structure, shaft cover 74 also comprises the threaded insert 82 in the molded end flange 84 of advancing shaft cover 74.But threaded insert 82 can comprise the structure that makes the insert moulded-in-place, for example annular knurl and/or one or more rib or flange.
Shaft overlaps another embodiment as shown in figure 10, and wherein Figure 10 is the exploded view of another embodiment part with golf clubs of replaceable shaft system.Be similar to hereinbefore described embodiment, golf clubs comprises shaft 90, and this shaft is couple to the hosel 92 of bar head by comprising the replaceable shaft system of shaft cover 94.
In this embodiment, shaft cover 94 adopts the form of many structures.Shaft cover 94 comprises with lining 98 all-in-one-piece main bodys 96 with by the shaft that the independent pin 100 that joins in main body 96 and the lining 98 forms and overlaps align structures.Pin 100 radially extends through the interface of main body 96 and lining 98, and engages securely with main body 96 and lining 98.Select the length of pin 100, the end of feasible pin 100 can laterally stretch out and exceed the outer surface of main body 96.Preferably, each end of pin 100 is laterally from main body 96 segment distance that stretches out, and this distance is equivalent to the thickness of sidewall of the hosel 92 of bar head, thereby makes the end of pin 100 roughly concordant with the outer surface of hosel 92.Though shown in pin 100 be generally cylinder component, should be understood that it can have any required section shape, and hosel 92 can comprise any hosel align structures with complementary shape.For example, pin 100 can be any key with polygon section shape, for example triangle, trapezoidal, square, rectangle and rhombus etc.
