Description:

BACKGROUND

1. Field

A fastener for utilization with cleats for athletic footwear is disclosed. In particular, a two piece fastener including a pin and sleeve having an internal lock providing both moisture resistance and ease or removal is disclosed.

2. General Background

Athletic shoes may require the use of cleats or other antislip devices. The cleats made be made of metal of ceramic. One of the challenges for providing athletic footwear is to provide an efficient technique to attach the cleats to the shoe.

There are currently several types of fasteners utilized for placing metal cleats in athletic shoes. Previous designs for metal cleat includes utilizing a solid squeeze rivet for removal of the cleats. However, these designs do not allow removal and replacement of cleats once they are worn down from excessive use.

Other previous designs of cleat fasteners utilize an internal lock having a spline lock design wherein the pin contains locking splines on the shank of the pin. While providing for a removable fastener, the locking splines create grooves in the fastener that create leak points into the shoes, allowing excess moisture into the shoes.

Thus, there is a need to provide a fastener for attaching cleats to footwear that prevents leakage and still provides easy removability.

DETAILED DESCRIPTION

A fastener for attaching cleats to footwear is disclosed. The cleats provide improved traction for footwear. Any type of cleat may be utilized for any sport. In exemplary embodiments, the fastener is utilized to connect the cleat to the footwear. Looking now at the Figures, the fastener comprises a hollow sleeve 12 and a pin 14 which are to be joined together with an internal locking mechanism.

The hollow sleeve 12 has a generally straight shank portion 16 with a uniform outer diameter terminating at its outer end 18 with an enlarged head 20. The sleeve 12 has a central through bore 22 which includes a shank bore portion 24 and a reduced diameter bore portion 26. The hollow sleeve further comprises an annular stop shoulder 28 defined at the juncture of the shank bore portion 24 and the reduced diameter bore portion 26.

In an exemplary embodiment shown in FIG. 3, a small slit 30 separates the stop shoulder from the reduced diameter bore portion 24. In exemplary embodiments, the sleeve stop shoulder may terminate in a tapered portion 34 to assist in moving of the stop shoulder 28 into a locking position. The stop shoulder 28 has a similar outer diameter to that of the shank bore portion 26.

The pin 14 includes an elongated shank portion 38 terminating at one end with an enlarged head portion. The pin member 14 comprises an elongated generally smooth pin shank portion 42 and a generally smooth reduced diameter pin shank portion 48. In an exemplary embodiment, the enlarged head portion has an enlarged flush head 45. At the other end 50 of the pin member 14 has a slight taper 58 to help move the pin 14 into the reduced diameter bore portion 26 of the sleeve 12 during installation.

The diameter of pin shank portion 42 is generally the same as that of the shank bore portion 24 in the sleeve 12, i.e. slight clearance to slight interference. The smooth reduced diameter portion 48 is generally the same as that of the to provide a slight clearance to slight interference.

An annular pin stop shoulder 52 is defined by the juncture of the reduced diameter pin portion 48 and the pin shank portion 40 and has an end surface 57 which is generally planar. An annular internal locking section 44 is defined by an annular groove located immediately adjacent the pin stop shoulder 52.

In an exemplary embodiment, the annular internal locking section 44 of the pin 14 is formed to have its wall 46 curved. This assists the internal locking section 44 in retaining the lock material of sleeve stop shoulder 28 and resisting rearward push out of pin 14 during installation.

To install, at least one sole ply 60 for the construction of a shoe and a metal cleat 66 is placed between the pin member 14 and sleeve 12. In an exemplary embodiment, three sole plies will be place Installation force should be placed on both the outer end of the sleeve 18 and the enlarged head 40 of the pin 14 to press the pin 14 and sleeve 12 together.

As axial movement of the pin 14 continues the pin stop shoulder surface 52 engages the sleeve stop shoulder surface 28 moving it radially inwardly into the internal locking section 44. After the internal locking section 44 has been substantially filled, movement of the pin 14 is arrested and the relative axial force applied between the pin 14 and sleeve 12 maintains the pin locked into the sleeve member.

As previously discussed, the sleeve stop shoulder 28 is annularly separated for a selected distance along the annular slit 30. The slit 30 or separation enhances the radially inward folding action of the material of the sleeve stop shoulder 28 into the internal locking section of the pin 14.

In other exemplary embodiments, the sleeve stop shoulder surface 36 is inclined or tapered to assist the material of the sleeve stop shoulder 28 to be folded or moved radially inward. In this regard the engaging surface of pin stop shoulder 52 is oriented relative to that of the sleeve surface 36 such as to assist in the radially inward folding action; thus the material of sleeve stop shoulder 28 will be substantially directed radially inwardly and not radially outward.

The volume of the material of the sleeve stop shoulder 28 is selected relative to the volume of the internal locking section 44 such that the internal locking section will be substantially filled and axial movement of the pin 14 will be stopped at the desired location generally when that filled condition occurs, i.e. such that pin break at breakneck 60 occurs within the sleeve head. Thus, the volume of sleeve stop shoulder 28 which is separated from the remainder of the sleeve 12 by the tapered portion and slit 30 is generally equal to or greater than the volume necessary to fill the internal locking section 58 and adjacent area between the pin 14 and sleeve 12.

In exemplary embodiments, the pin stop shoulder surface 57 first acts to fold and/or deform the material of the sleeve stop shoulder 28 radially inward; as this occurs substantially all of the surface 57 (including that portion extending into internal locking section 44) will be active as a stop. When filling the internal locking section 44 the movement of locking material from the sleeve stop shoulder 28 is generally entirely radially inward.

Upon installation of the fastener, the enlarged head of the pin will interact with the top layer 70 of sole plies 60. The enlarged head 45 of the pin will press into the sole ply 60 so that the top 70 is flush with the end 40 of the pin member 14, improving the comfort of the footwear.

The fastener also allows for easy removal and replacement of cleats utilizing a tool 90. The tool 90 with include a punch or drill piece 92 that will interact with the outer end of the pin member. To remove the fastener, the tool 90 can be pushed into the through bore of the sleeve 12 punching the outer end 50 of the pin member 14, and pushing the pin member 14 out of the sleeve 12.

In exemplary embodiments, there will be exhibited external flushness of the pin 14 with the external head surface 18 of the sleeve. The flushness of the outer end 18 of the sleeve 12 and the outer end 66 of the pin 14 provides visual confirmation of proper installation. This flushness also prevents water from seeping though the fastener 10 and provide moisture resistance to the shoe.

Additionally, the disclosed construction of the fastener promotes good filling of the locking section 44 and also minimizes variations in the axial position of the pin 14 at which the groove 58 is filled. As a result, any moisture would be prevented from entering the shoes via the cleat fastener 10.

The fastener and uses disclosed herein include any combination of the different species or embodiments disclosed. Accordingly, it is not intended that the scope of the disclosure in any way be limited by the above description. The various elements of the claims and claims themselves may be combined any combination, in accordance with the teachings of the present disclosure, which includes the claims.
