Abstract

A shoe cleat is adapted to be removably secured in a holder provided on the shoe sole. 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 a locking means (26, 28) becomes interengaged to resist subsequent unscrewing of the assembly. The locking means comprises 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. 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 interangagement of the locking means.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to an improved mounting of a shoe cleat for use in a shoe sole or heel.

It is well known to attach non-slip, for example, to the bottom of a golf shoe via a threaded spigot. A threaded spigot is located on the top of the cleat and is adapted to engage a corresponding threaded socket formed in the sole. The socket is usually provided as a separately formed receptacle. The receptacle may be incorporated and merged with the molded sole, or may be mounted within a composite sole structure, including leather, EVA, or other sheet material forming the outsole. You may. Typically, the cleats are loosened and can be removed so that they can be replaced if they become excessively worn or damaged.

[0003] The non-slip installed in this manner may be a stud or spike that pierces the ground (such as that disclosed in GB-A-2028102), or other form of ground-grabbing element (such as EP-A). A-0342232). These protrude from the lower surface of the disk-shaped flange body. The spigot protrudes from the upper surface of the flange body.

[0004] The best known form of threaded non-slip utilizes a single thread instead of a multiple thread. Single-threaded screws are better than multi-threaded screws in that they are not only the easiest screw structure, but also provide greater resistance when trying to loosen the screw after the antiskid is firmly inserted into the socket. ing. However, whether inserted by hand or assembled by an automatic machine at the factory, it is advantageous to use multi-start screws. In particular, the use of a multi-start thread with a steep angle of torsion angle allows the insertion of a spigot of any given length into the socket with less rotation and therefore a shorter insertion time can do. further,
When a multi-start thread is used, when screwing is started from an arbitrary angle, the average required rotation amount until the screw engages is small. Further, since the multi-start thread is formed by cutting deeper than the single-start thread, the shear strength of the thread becomes higher. Therefore,
The length of the spigot can be reduced.

[0005] There is a recent trend to use ground gripping elements of softer materials. The durability of such cleats is quite low. Therefore, golfers need to replace the antiskid more frequently. Also, it has become common for golfers to have different sets of non-slip sets to meet different requirements. Before playing, look at the conditions of the course and change the slip according to the result.
If using a single-start thread system, replacing the non-slip would be a long and hard task. It has to be turned many times to remove and insert the non-slip. This is often done by hand, so many golfers have been forced to give up while admitting the need to replace the antiskid.

[0006] In order to eliminate the great labor involved in fixing with a conventional single-thread screw, that is, the point of having to rotate many times when inserting and removing the non-slip, a bayonet type (insert and twist) Non-slip fixing method has been proposed. With a bayonet type connection, the non-slip can be attached to and detached from the holder at a very small rotation angle. However, in practice, such a quick coupling connection scheme is not entirely satisfactory. First and foremost, the load that acts in use to attempt to tear the cleat from the holder can be quite large. Screw connections are relatively solid and the contact area to support the load between components is widely distributed, while bayonet-type connections rely on very few points of contact, The point of contact must support all loads and can be severely damaged (eg shearing bayonet pins). When such damage is received, if the damaged portion is not the entirety, the damaged non-slip may be difficult to remove, and the non-slip may be lost due to the damage. Secondly, anti-skids are designed to slide easily into and out of the holder, but in practice, slippage may occur due to component distortion, soil intrusion, or the action of protection systems. The passage where the stop enters is easily obstructed.

[0007] For these various reasons, the use of multi-start screws has become attractive. One example using a multi-start thread form is disclosed in WO 91/04685. This is for a double thread.

[0008] Many forms of locking ratchets have been proposed to prevent inadvertent loosening of the anti-slip screw (whether using single or multiple threads). In many of these, play is provided only in the last step of inserting the spigot into the socket. For example, a commonly proposed configuration is to provide opposing annular teeth on a plane perpendicular to the axis of the screw such that the teeth engage each other. In such a configuration, there is little variation in the depth (degree) at which the teeth interengage, and therefore, if the locking ratchet is properly engaged, the depth of insertion of the spigot into the socket is reduced. Also has little change. The width of the change here is important if the socket is provided in a composite sole structure. This is because there is no guarantee that the outer surface of the outsole is manufactured to the correct level (height) for the socket.

Another type of lock ratchet that solves such a disadvantage is disclosed in US-A-50366.
06. In this configuration, radially projecting teeth arranged in a ring on one component are adapted to engage with axially extending splines arranged about the ring of the other component. ing. As the spigot is inserted into the socket and the two components are rotated relatively, the teeth ride over the splines (the teeth enter the space between the splines). The axial length of the spline should not exceed the depth at which the spigot is inserted into the socket.
The teeth and the splines are of such a degree that they can cooperate perfectly with each other. However, it has been found that with this arrangement, the teeth and / or splines are heavily worn and the system fails after many insertions and removals of the cleat.

It is an object of the present invention to provide an improved non-slip shoe for a shoe, which can still provide an effective locking action beyond the depth of insertion of the spigot into the socket. It is to provide a combination of holders.

According to the invention, in combination with a non-slip shoe and a holder, a threaded spigot of one of the two components is inserted into the threaded socket of the other component while rotating. The spigot is thereby inserted into the socket to allow the components to come together into an assembly and to resist loosening of the assembly after assembly. Wherein the locking means of the two components are adapted to engage with each other, wherein the locking means extends axially from one of the components and A column arranged in a ring shape, and teeth protruding in the radial direction at the other component and arranged in a ring shape, wherein the teeth are arranged in the ring shape. The pillars and the teeth are arranged in the ring-shaped has, are coaxial arrangement with the axis of the screw, at least the second half of the stages in the spigot is inserted into said socket,
When the column arranged in the ring shape and the teeth arranged in the ring shape rotate relative to each other, by engaging the teeth and the column, the column is elastically bent, and the teeth are A combination of a non-slip shoe and a holder is provided, characterized in that the engagement between the columns results in mutual engagement of the locking means.

The range of axial length of the post ensures that locking can be achieved over the entire depth of insertion as long as the post and the teeth together form an effective locking means. It is assumed to be a degree. At this time, the elasticity of the columns minimizes wear.

The number of teeth can be an integer multiple of the number of columns. The integer can be 1, and the number of teeth can be the same as the number of columns. As in the prior art, the spigot may be provided on the non-slip and the socket may be provided on the holder, or the arrangement may be reversed.

Further, it is preferable that the ring-shaped column is provided on the non-slip, and the ring-shaped teeth are provided on the holder. Most preferably, the teeth are the hubs of the holder (forming a threaded socket)
The teeth protrude from the outer cylindrical surface of the spigot, the teeth in use are received in a ring-shaped post, and the hub is received in an annular recess formed between the spigot and the post.

[0015] Preferably, when the teeth are engaged in the recesses formed between the spaced columns, the teeth can smoothly pass through the surfaces of the columns between the engagements. As such, the post shall have a radially-facing inner surface with a profile that is convex toward the ring-shaped teeth. The ends of the inner surface on both sides in the circumferential direction may have different profiles, and the resistance to the movement of the teeth passing through the column may be different between the case of screwing and the case of loosening the screw. Desirably, the respective profiles are determined so that the resistance when tightening the screw is smaller than when loosening the screw. This simplifies insertion and prevents failure from loosening the anti-slip screw. The columns may be arranged in pairs, with each pair of columns having a common base, or each column may be erected without restraint.

The spigot and socket screws are preferably multi-start screws (most preferably triple start screws). This allows a quick and effective assembly of the stud and holder. Most preferably, the number of columns in the ring is an integer multiple of the number of threads. For example, when three-start screws are used, the number of columns is 6, 9
Or it becomes 12.

The profile of the inner surface of the column, which is oriented radially, is one of the features of the present invention. According to the present invention, there is provided a shoe non-slip having a threaded spigot which is rotatable and insertable into a socket of a holder, and which is inserted together with the holder to form an assembly. A column arranged in a link shape, each of which is erected without restriction and extends in the axial direction so as to engage with a plurality of teeth provided on the holder,
Each of the columns has a radially-facing inner surface, the inner surface having a central region having a convex profile and first and second surfaces having different profiles.
And a circumferential end of the shoe.

Since the profiles of the first and second circumferential ends are different from each other, the teeth are different between when the non-slip is inserted into the holder and when the non-slip is removed from the holder. The resistance of the post to the teeth as it passes through the post can vary.

Preferably, the profile is such that when the non-slip is inserted into the holder,
It shall be shaped so that the column exerts less resistance on the teeth than when the cleat is removed from the holder. Of the circumferential ends, the circumferential end that becomes the leading end when the non-slip is inserted into the holder has a profile that is concave toward the teeth to facilitate the passage of the teeth. You may. on the other hand,
Of the circumferential ends, the circumferential end that becomes the leading end when the antiskid is removed from the holder has a profile that is convex toward the teeth, and the screw is loosened when it is not necessary to loosen the screw. Resistance to movement may be provided.

If the cleats are made of different materials, the friction and elastic properties of the columns will also be different. The profile of the circumferential ends can also be changed accordingly, so that each anti-slip, no matter what material is made, will have approximately the same force for both insertion and removal. It may be necessary to be applied.

In the non-slip shoe according to the present invention, as in the case of the combination of the non-slip shoe and the holder described above, each column may be erected without being restrained, or , The columns may be arranged in pairs, with each pair of columns having a common base. The spigot screw is preferably a multi-start thread, most preferably a triple start thread.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The structures of the components forming the studs and sockets that can be engaged with each other and the manner of cooperation are merely examples and do not limit the present invention.

Non-slip shoes for shoes in the form of studs suitable for use in golf shoes
1 and 2) include a disk-shaped flange 10. A threaded spigot 12 protrudes from the upper surface of the flange, and a ground spike 14 protrudes from the lower surface of the flange. The spigot and spike are located in the center of the flange. The flange and the spigot are made by integral molding of a plastic material. The spikes are formed by metal pins that extend axially through the molding and are attached to the molding by rivets.

The stud is adapted to be attached to the bottom or heel of a golf shoe by a holder in the form of a receptacle (FIGS. 3 and 4) forming a socket. The receptacle includes a hub 16 having a threaded socket hole 18. The hole in the hub is closed at the upper end 20. A flange 22 surrounds the hub, and an opening 24 is formed in the flange. For use, the receptacle is complementary into the molded or compound outsole (or heel) of the golf shoe to expose the threaded hole 18 and attach the stud to the shoe. The spigot 12 provided with a suitable screw is received. The receptacle is formed as an integral molding of a plastic material.

Such combinations of studs and receptacles are well known in the art to the extent described above. In the present invention, the mutually complementary thread form of the stud and the receptacle is a triple thread, which has a relatively steep torsion angle so that the stud can be inserted into the receptacle with a minimum rotation angle. Can be inserted into Locking means is used to screw the stud into the receptacle. This is because the steep torsion angle has a relatively small frictional resistance against the loosening of the screw. The locking means includes teeth 26 extending axially and arranged in a ring.
These teeth 26 are formed on the outer periphery of the hub 16 of the receptacle.
Will engage the inner surface of the collar 28 when inserted into the collar 28.

As shown in FIGS. 3 and 4, the teeth 26 project radially outward from the outer cylindrical surface 30 of the hub 16. The teeth 26 are in the form of short squat ribs extending in a direction parallel to the axis of the hub 16. When viewed in cross section, the ribs are generally triangular in shape, but have rounded vertices. The ribs are uniformly distributed around the hub 16 so as to form a ring shape coaxial with the axis of the hub 16. In the illustrated example, twelve ribs are provided at an angular interval of 30 degrees.

Stud collar 28 (FIGS. 1 and 2) extends axially from flange 10 and extends approximately half the height of threaded spigot 12. A collar 28 coaxially surrounds the spigot 12. An annular recess 32 is formed between the spigot 12 and the collar 28 for receiving the hub 16 of the receptacle. Collar 28 includes twelve individual segments arranged in a ring. These segments form a pillar 34 which stands up without being restrained. The pillars 34 are uniformly distributed at an angular interval of 30 degrees around the axis of the stud. The columns 34 are separated from one another by narrow slits 36. Of pillar 34,
The radially facing outer surface 38 makes up the outer cylindrical surface of the collar 28. Pillar 3
4, the radially inner surface 40 (facing the teeth 26 in the assembly) is slightly convex when viewed in a plane perpendicular to the axis of the stud (FIG. 2), and has a collar. 28 define the inner surface. The inner surface of the collar 28 is divided by a slit 36 and undulates so as to substantially undulate in the circumferential direction around the axis of the stud.

The distance to the radially projecting end of the tooth 26, as measured from the axis of the receptacle, is substantially equal to the distance to the inner surface of the post 34 at a circumferential position immediately adjacent to the slit 36. That is, unless the teeth 26 of the receptacle are radially aligned with the slits 36 of the collar, there is a radial interference between the teeth 26 and the post 34, which results in friction against relative rotation between the components. Resistance occurs. Rotation of the stud relative to the receptacle is resisted by the successive engagement of teeth 26 with post 34. When the stud is fully inserted into the receptacle, or when it is partially inserted (provided that the teeth and the post interengage with each other)
This is also true.

The teeth 26 are substantially incompressible. Therefore, the columns 34 which are erected without restraint flexibly elastically, so that the teeth can easily pass through the columns when the components are relatively rotated. The convex profile of the posts 34 facilitates the teeth to cross over the surface of the posts as they successively engage in recesses formed between the spaced posts. . As the spigot 12 is screwed into the socket, the post 34 becomes less and less flexible and the resistance to teeth passing through the post increases (as the teeth approach the base of the post in the flange 10). ). This reduces the risk of over-tightening the stud in the receptacle. The stud is fully inserted into the receptacle as the spigot rotates 120 degrees with respect to the socket after the spigot and socket screws first engage (interengage). In this position, the receptacle teeth 26 are in opposition to the slits 36 between the stud collar columns 34.

The locking post 34 on the stud physically flexes outwardly as it is traversed by the locking teeth 26 of the receptacle and returns to its original position when engaged in the recess between the teeth. Return to position. This physical movement is independent of the clearance of the screw and is not affected by the shape of the screw. This physical movement tightly connects the two components of the screw assembly, thereby providing strength, resisting the tendency to dislodge, and positioning the components that are mated together during assembly. It will be easier.

FIG. 5 shows another embodiment of a collar 28 on a stud. The same reference numerals are used for parts corresponding to the previous embodiment. In the embodiment of FIG. 5, instead of individual columns 34, paired columns 42 are used. Each pair of pillars has a common base 44
have. The radially inner surface 40 of each post 42 is also different from the previous embodiment. Although they are almost convex toward the teeth, the circumferential ends of the surface are not mirror symmetric. Instead, each inner surface 40 has a central convex region, a first circumferential end 48 having a concave profile towards the teeth, and a second circumferential end 48 having a convex profile towards the teeth. Directional end 50. When the stud is inserted into the holder, the first end 48 becomes a leading end and the second end 50 becomes a trailing end. This relationship is reversed if the stud is removed from the holder. The concave profile at the first end 48 gives less resistance to the teeth when inserting the stud, and the convex profile at the second end 50 gives more resistance to the teeth when removing the stud. This makes it relatively easy to insert the stud, while preventing the stud from accidentally coming off.

The profiles of the ends 48, 50 may be varied to vary the torque required for screwing and unscrewing, and may be varied to take advantage of the different frictional and elastic properties of different materials. .
