Abstract

In a combination of shoe cleat and holder, a screw-threaded spigot (12) on the cleat is inserted with rotation into a complementary socket (18) of the holder, and has a ring of free-standing posts (34, 42) extending axially from the cleat and a ring of radially-projective teeth (26) on the holder, the rings being co-axial with the screw axis so that during at least later stages of insertion of the spigot (12) into the socket (18), on relative rotation of the rings, engagement of the teeth (26) with the posts (34, 42) causes the posts (34, 42) to deflect resiliently and engagement of the teeth (26) between the posts (34, 42) causes interengagement of the locking means.

Description

The footwear wedge

The present invention relates to set among sole and footwear root footwear wedge (shoe cleats) and the improvement that this is carried out.

When setting the footwear wedge on the sole of for example golf shoes, known is to be undertaken by the screw thread plug on the footwear wedge, and this plug matches with respective threads socket in the sole at last.This socket is normally provided by the independent mounting that forms in can being combined at the bottom of the cemented shoe, maybe can be set on the composite sole structure of the leather, EVA or other flaky materials that include the formation outsole.Generally, such footwear wedge can be backed out replacing when its excessive wear or damage.

The footwear wedge that sets in a manner described can have following side-prominent from a disc-shaped flange body, stabs bolt shape spare or the spike (described in GB-A-2028102) or the other forms of earthing member (described in EP-A-034232) on ground.

The footwear wedge of most thread forms utilizes one start screw but not multiple thread.One start screw is except being the simplest thread forms, also is the anti-resistance of unscrewing that can provide bigger after the footwear wedge inserts socket tightly than the superior part of multiple thread.But when wanting to insert by hand and assembling, then can benefit by adopting multiple thread by full-automatic factory.Particularly, multiple-threaded steeper helical angle can allow the plug of any given length through less rotation thereby can insert socket quickly.In addition, multiple thread is when from when starting orientation arbitrarily, average required amount of spin in the time of reducing thread engagement.Have again,, therefore allow short plug length because the multiple-threaded line of cutting also just can have bigger shear strength deeply than single-threaded.

The current trend of seizing the ground part that a kind of employing is arranged than flexible plastic.The life-span of such footwear wedge is short significantly.So the golfer needs to change more continually the footwear wedge.Simultaneously, the golfer will have not footwear wedge on the same group adapt to different conditions usually, so that changed the footwear wedge according to the result that field conditions is judged before motion.If adopt the one start screw system, because corresponding footwear wedge need repeatedly rotate when unloading and insert, the replacing of shoe-peg can be work time-consuming and effort.This usually is a handwork, so that hinders many golfer Chang Buneng to change its footwear wedge on request.

As overcoming required insertion of repeatedly rotating of traditional one start screw joint and the numerous confused work of unloading, employing bayonet type joint had been proposed; By the combination of bayonet type, only need rotation seldom just relative its mounting of footwear wedge to be connected or disconnect.But in practical operation, the combination of this quick connection does not prove and can be entirely satisfactory.It is very big at first in use being used for the load of footwear wedge when its mounting is backed out.Though the screw thread binding energy provides bigger and well distributed zone for the contact of the carrying between the relevant parts, but the combination of bayonet type then only relies on seldom several points that must bear whole load, thereby serious damage (for example relating to the shearing of bayonet pin) can take place.When such damage takes place,, then remove impaired footwear wedge and be difficult for if be not to be that all damages and footwear wedge are lost again.Secondly, although can the footwear wedge be designed to can be directly relatively its mounting slide into and skid off, in practical situation, the meeting of passing through of footwear wedge is hindered, this or because the distortion of parts or because the intrusion of dust makes the operation of this system impaired.

Because above various reasons, it is attractive adopting multiple thread.Adopt the example of multiple thread form to see in the specification of WO91/04685, what wherein describe is double thread.

Can not unscrew (no matter employing is single head or multiple thread) because of contingent in order to ensure the footwear wedge, propose the sealed ratchet of various ways, many just just working at last wherein at plug insertion socket.For example a kind of device that generally proposes for example used get relative annular array form on perpendicular to screw shaft surface can intermeshing tooth group.Such arrangement form makes intermeshing tooth have only very little variation leeway on the degree of depth, thereby when sealed ratchet meshed rightly, the change in depth of plug insertion socket correspondingly also had only very little leeway.This change in depth can be very important when socket is located in the composite sole, and this is because generally can not make the outer surface of outsole keep accurate plane with respect to socket in manufacture process.

Another kind can be used for overcoming the sealed ratchet formal description of above-mentioned difficulties in U.S. Patent No. 5036606.In described structure, the tooth that on the parts a circle is radially outstanding is arranged to be meshed with the axially extended teeth groove of arranging around another parts lopping, when this two parts in plug insertion socket and when relatively rotating, above-mentioned tooth just is stacked and placed on the teeth groove and (enters the space between teeth groove).The axial dimension of teeth groove can cooperate it fully with tooth in the depth bounds of plug insertion socket.But the applicant finds that under this device form tooth and/or teeth groove can be made whole system lose efficacy in the insertion of passing through several times or after unloading by heavy wear.

On the footwear wedge, one enclose independently that the profile of the inner radial surface of column piece and column piece has constituted theme of the present invention.

Have that the screw thread plug of socket in rotatable insertion one mounting and a circle extend vertically and the column piece that cooperates of the tooth in the mounting therewith according to footwear wedge of the present invention, the inner radial surface that each column piece has is crooked profile, such profile has the convex region and the first and second peripheral terminals of central authorities, and this first and second terminal has different profiles again.

The first and second peripheral terminals have different profiles to mean when the footwear wedge inserts and unloads with respect to mounting, and these column pieces provide different resistances for the athletic meeting of tooth by them.

The profile of above-mentioned terminal preferably is arranged to the resistance to tooth that column piece is provided, when when the footwear wedge inserts, unloading less than the footwear wedge.The peripheral terminal of guide's end can have the recessed profile towards tooth during as insertion, to help passing through of tooth.Guide when another peripheral terminal promptly unloads end then preferably has the convex towards tooth, unscrews in opposing when not required helping.

If the footwear wedge is to be made by different materials, then the frictional behavior of column piece and elastic characteristic are also with different.At this moment can change the profile of peripheral terminal,, when inserting and unload, require to apply approximately uniform power no matter it with which kind of material is made to guarantee each footwear wedge.

The column piece here can be to be provided with in pairs and each is to having common base.The screw thread of plug is multiple thread preferably, particularly preferably 3 head threads.

Be elaborated referring to the footwear wedge of pieceable post bolt form and the accompanying drawing of socket formation parts below, these parts have been set forth various aspects of the present invention with way of example by the mode of its structure and collaborative work mutually.In the accompanying drawings:

Fig. 1 is the side cutaway view of the footwear wedge of post bolt form;

Fig. 2 is the top plan view of this post bolt;

Fig. 3 is the side cutaway view of mounting (socket formation parts);

Fig. 4 is the flat sheet of the bottom view of this mounting;

Fig. 5 and Fig. 2 are similar, show the part of bright another embodiment.

The footwear wedge that is post bolt form that is adapted on the golf shoes has disc-shaped flange 10.Screw thread plug 12 is flange last side-prominent from then on, and 14 of the spikes of ground connection are flange following side-prominent from then on, and this plug and spike all are in the central authorities of flange.Flange and plug all are by plastic unit formula ground die forming, and this spike is to be formed by the metallic pin that passes through this moulded parts vertically, and is fixed in this moulded parts by the riveted joint mode.

Above-mentioned post bolt is arranged to and can be installed on the sole or footwear root of golf shoes by the mounting (Fig. 3 and 4) that socket forms the mounting form.This mounting comprises the lining 16 with threaded socket hole 18, and the hole of this lining is the sealing of 20 places in the upper end.Around lining 16 flange 22 is arranged, be formed with many holes 24 on this flange.During use, this mounting is packed in the molded or compound outsole (or footwear root) of golf shoes, and the screwed hole 18 that manifests it is used for admitting the screw thread plug 12 of auxilliary mutually described post bolt and this post bolt is fixed on the footwear.This mounting is the modular moulded parts formation as plastics.

The conjunction of described so far this post bolt and mounting is known in this technology.

Among the present invention, this auxilliary mutually thread forms of post bolt and mounting is 3 head threads, and steeper helical angle is provided, and can allow the post bolt only need do minimum rotation and just can insert in the mounting.For making the post bolt firm when being screwed into mounting, owing to the steepness of screw thread causes the lower lock uint that adopted of frictional resistance when unscrewing.This lock uint comprises the tooth 26 that a circle extends vertically, and they form around the outside of mounting lining 16, and the inner surface combination of ring therewith when this lining inserts on post bolt in the ring 28.

Shown in Fig. 3 and 4, tooth 26 is from the cylindrical outer surface 30 of lining 16 evagination radially, and these teeth are got along being parallel to the short and thick rib-shaped piece form that lining 16 axis directions extend, and the cross section of rib-shaped piece is roughly triangular in shape but the drift angle of rounding is arranged.These rib-shaped pieces coaxially evenly distribute around the lining axis, are provided with 12 rib-shaped pieces altogether by 30 ° of intervals.

The ring 28 of above-mentioned post bolt (Fig. 1 and 2) is extended vertically from flange 10, its highly be approximately its coaxial line around the height half of screw thread plug 12.Between plug 12 and ring 28, be formed with the annular wells 32 that is used for admitting lining 16.Ring 28 comprises a circle totally 12 fan-shaped section of separating that form independent column piece 34, and they evenly are distributed by 30 ° of intervals around the axis of post bolt, and these column pieces are separated by narrow slit 36.The radially-outer surface 38 of column piece 34 has been formed the cylindrical outer surface of ring 28.The inner radial surface 40 of column piece 34 (in the sub-assembly that is assembled into towards tooth 26) dimpling in perpendicular to the plane of post stud shaft line (Fig. 2), make ring 28 for the inner surface of narrow slit 36 blockings along peripheral direction undulate around post stud shaft line.

Tooth 26 is substantially equal to such distance of the inner surface of column piece 34 at the peripheral position of next-door neighbour's narrow slit 36 from the radial projection distance of mounting axis.In other words, except when the tooth 26 of mounting during radially with narrow slit 36 collimation of ring, causes frictional resistance for relatively rotating of these parts with regard to having diametral interference between tooth and column piece.So this post bolt just can be owing to tooth 26 progressively is obstructed with the combination of the column piece 34 that continues mutually with respect to the rotation of mounting.Like this, to want the end be to insert within the mounting or just just partly insert (supposition insert degree tooth and column piece are mutually combined) fully to this post bolt.

Tooth 26 is incompressible basically, places reliably under the elastic deflection influence of independent column piece 34, so that tooth 26 is easy to pass through from column piece when described two parts relatively rotate.The nonreentrant surface profile of column piece 34 makes tooth 26 to become the column piece surface between the junction surface in the groove by it in the neutral gear of each separated column piece glossily.When plug 12 was screwed in the socket, column piece 34 was difficult for deflection, thereby had increased resistance for tooth by them (when the bottom of tooth convergence flange 10 place's column pieces).This drag energy is used for preventing that the post bolt from crossing twists all danger that is incorporated in the mounting tightly.When plug turns over 120 ° with respect to socket, after plug and socket screw thread were done initial being meshing with each other, the post bolt just was inserted within the mounting fully.On this position, just herewith the narrow slit between the column piece of post bolt ring is relative for the tooth 26 of mounting.

Outwardly substance distortion just takes place on by the sealed tooth 26 on the mounting at it in sealed column piece 34 on the post bolt, and when combining with the groove of between cog just return.This substantial motion is not depended on the gap of screw thread thereby is not subjected to the influence of thread construction geometry, can allow two closely couplings of parts of this thread set component, make that the parts of these two couplings have intensity when combination, can resist and take and be easy to the location apart.

Fig. 5 shows another embodiment that understands ring 28 on the post bolt, gives corresponding parts attached with corresponding label simultaneously.Different with the column piece 34 of separate type, the column piece 42 among Fig. 5 is paired, every pair of shared same base 44.The inner radial surface 40 of each column piece 42 also is different.Though the peripheral terminal on these surfaces is still usually protruding in tooth, they are not the minute surface symmetries.On the contrary, inner surface 40 comprises: central convex region 46, have towards the first peripheral terminal 48 of the recessed profile of tooth, have the second peripheral terminal 50 towards the convex of tooth.When the post bolt being inserted in the mounting, first terminal 48 is front ends and second terminal 50 is tail ends, and when the post bolt was taken out from mounting, situation was then opposite.The recessed profile of first terminal 48 provides less resistance for tooth when the post bolt inserts, the convex of second terminal 50 then provides big resistance to tooth when removal post bolt.The post bolt is more easily inserted also can prevent that it from being deviate from by accident.

The profile of terminal 48,50 can change with change to be tightened and required torque when unscrewing, or provides different frictional behavior and elastic characteristics for different materials.
