Replaceable bicycle shoe cleat assembly

Abstract

A replaceable bicycle shoe cleat assembly includes a first cleat member and a second cleat member, which can be replaced independently from a bicycle shoe when worn out. Therein, the new cleat member can get positioned by the remained member and thus be accurately fixed to the bicycle shoe at a position where the replaced cleat member was formerly installed.

What is claimed is: 
     
         1 . A replaceable bicycle shoe cleat assembly, comprising:
 a first cleat member having:
 a first fastening portion including at least one first through hole, the first through hole allowing a screw to pass therethrough and then engage with a slot formed on a shoe sole, so as to fasten the first cleat member to the shoe sole; and 
 a first positioning portion; and 
   a second cleat member having:
 a second fastening portion including at least one second through hole and at least one third through hole, the second through hole and the third through hole allowing screws to pass therethrough and then engage with two other slots formed on the shoe sole, so as to fasten the second cleat member to the shoe sole; and 
 a second positioning portion for mating the first positioning portion,
 wherein, the first positioning portion of the first cleat member and the second positioning portion of the second cleat member are configured to ensure that the first and second positioning portions are limited to be mated with each other in only one orientation, and when any of the combined first and second cleat members receives a horizontal driving force, the horizontal driving force is transmitted to the other of the first and second cleat members. 
 
   
     
     
         2 . The replaceable bicycle shoe cleat assembly of  claim 1 , wherein the first positioning portion of the first cleat member is in a W-like shape bilaterally formed with paired arms, each said arm being terminated with an anchor extending in a direction perpendicular to an axis of the arm, the first positioning portion being centrally formed with a promontory between the two arms, while the second positioning portion is shaped as a recessed portion for fittingly receiving the first positioning portion, the second positioning portion having arm recesses for fittingly receiving the arms, anchor recesses for fittingly receiving the terminal anchors of the arms, and a promontory recess for receiving the promontory, so that the first positioning portion and the second positioning portion are limited to be mated with each other in a single posture. 
     
     
         3 . The replaceable bicycle shoe cleat assembly of  claim 1 , wherein the first positioning portion and the second positioning portion include a noncircular mortise and a noncircular tenon that is limited to tightly fit the noncircular mortise in a single posture. 
     
     
         4 . The replaceable bicycle shoe cleat assembly of  claim 3 , wherein the noncircular mortise and the noncircular tenon are a rectangular mortise and a rectangular tenon that are tightly mated with each other. 
     
     
         5 . The replaceable bicycle shoe cleat assembly of  claim 1 , wherein the first fastening portion has a front end, or an end opposite to the first positioning portion, formed with a front engaging edge for engaging a front clamping member of an external clipless pedal, and the second fastening portion has a rear end, or an end opposite to the second positioning portion, formed with a rear engaging edge for engaging a rear clamping member of the clipless pedal, while the rear engaging edge is sized to be horizontally loosely received in the rear clamping member. 
     
     
         6 . The replaceable bicycle shoe cleat assembly of  claim 1 , wherein the first fastening portion has a front end, or an end opposite to the first positioning portion, formed with a front engaging edge for engaging a front clamping member of an external clipless pedal, and the second fastening portion has a rear end, or an end opposite to the second positioning portion, formed with a rear engaging edge for engaging a rear clamping member of the clipless pedal, while the rear engaging edge is sized to be horizontally fittingly received in the rear clamping member.
