Double flush fastener for attaching cleats

Abstract

A two piece fastener for securing at least one sole member to a metal cleat to provide better traction in footwear is disclosed. The fastener comprises a pin member and a sleeve member having an internal locking mechanism. In exemplary embodiments, the internal locking mechanism is defined by axial movement of the pin to engages a sleeve stop shoulder in a through bore located in the sleeve moving it radially inward into the internal locking section of the pin. After the internal locking section has been substantially filled, the pin and sleeve are locked together stopping movement of the pin. The fastener provides both water resistance and easy removability with the use of a tool.

1 . A fastener for securing at least one sole member to a metal cleat to provide better traction in footwear comprising:
 a sleeve member having an enlarged head sleeve shank portion, a through bore, the through bore having an enlarged bore portion and a reduced diameter bore portion and a sleeve stop shoulder;   a pin member having an enlarged head, an enlarged shank portion, and a reduced diameter shank portion, the reduced diameter shank portion having a diameter about the same as and providing a clearance with the reduced diameter bore portion, wherein at a juncture of the shank portion and reduced diameter shank portion is a pin stop shoulder, the reduced diameter shank portion having an internal locking section adjacent the pin stop shoulder; and   wherein the pin stop shoulder and sleeve stop shoulder have an engaging surface for directing the material of the sleeve stop shoulder substantially radially inward into the internal locking section to lock the pin and sleeve together and stop axial movement of the pin into the sleeve during installation.   
   
   
       2 . The fastener of  claim 1  wherein the internal locking section has a curved wall to facilitate movement of the sleeve stop shoulder into the internal locking section. 
   
   
       3 . The fastener of  claim 1  wherein the sleeve stop shoulder is separated from the bore portion of the sleeve by an annular slit to facilitate easier movement of the stop shoulder into the internal locking section of the pin. 
   
   
       4 . The fastener of  claim 1  wherein the sleeve stop shoulder terminates in a generally tapered portion defined by a surface extending radially inward and downward toward outer end of pin. 
   
   
       5 . The fastener of  claim 1  wherein the sleeve stop shoulder has a volume sufficient to generally fill a volume defined by the internal locking section of the pin. 
   
   
       6 . The fastener of  claim 1  wherein a tool having a punch may be utilized to remove the fastener from the metal cleat. 
   
   
       7 . The fastener of  claim 1  providing a double flush fastener that resists the entrance of water into the footwear. 
   
   
       8 . A fastener for securing at least one sole member to a metal cleat to provide better traction in footwear comprising:
 a sleeve member having an enlarged head sleeve shank portion, a through bore, the through bore having an bore portion and a reduced diameter bore portion;   a pin member having an enlarged head, a shank portion with a diameter, and a reduced diameter shank portion, the reduced diameter shank portion having a diameter about the same as and providing a clearance with the reduced diameter bore portion, the reduced diameter shank portion; and   wherein an internal locking mechanism directs a portion of material of the sleeve substantially radially inward to lock the pin and sleeve together and stop axial movement of the pin into the sleeve during installation   
   
   
       9 . The fastener of  claim 8  wherein the internal locking mechanism is a pin stop shoulder at a juncture of the shank portion and reduced diameter shank and a sleeve stop shoulder engaged by the pin stop shoulder for directing the material of the sleeve stop shoulder substantially radially inward into the internal locking section to lock the pin and sleeve together and stop axial movement of the pin into the sleeve during installation. 
   
   
       10 . The fastener of  claim 9  wherein the internal locking section has a curved wall to facilitate movement of the sleeve stop shoulder into the internal locking section. 
   
   
       11 . The fastener of  claim 9  wherein the sleeve stop shoulder is separated from the bore portion of the sleeve by an annular slit to facilitate easier movement of the stop shoulder into the internal locking section of the pin. 
   
   
       12 . The fastener of  claim 9  wherein the sleeve stop shoulder terminates in a generally tapered portion defined by a surface extending radially inward and downward toward outer end of pin. 
   
   
       13 . The fastener of  claim 9  wherein the sleeve stop shoulder has a volume sufficient to generally fill a volume defined by the internal locking section of the pin. 
   
   
       14 . The fastener of  claim 8  wherein a tool having a punch may be utilized to remove the fastener from the metal cleat. 
   
   
       15 . The fastener of  claim 8  providing a double flush fastener that resists the entrance of water into the footwear.
