Abstract
Abstract A bicycle pedal system comprising a shoe clip which attaches to a bicyclist's shoe and has a pair of serrated lateral tongues which couple with and are easily inserted into complementary serrated recesses in the associated bicycle pedal. The construction and configuration of the system, including the negative undercut serrations permits easy insertion of the clip into the pedal and permits relatively easy lateral sliding of the clip along the pedal and lateral removal of the clip from the pedal when not in use, but securely lock the clip in the pedal against relative lateral movement during use as well as against transverse separation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
142 words
A bicycle pedal system comprising: a pedal formed of rigid material and being adapted for mounting along a rotational axis thereof to a bicycle and having a pair of lateral grooves therein, each groove being defined by two faces oriented in a V-shaped configuration and having lateral serrations of negative undercut configuration in at least one face thereof; and a shoe clip formed of rigid somewhat flexible material and being adapted for attachment to a shoe and having a pair of lateral tongues of generally triangular configuration extending downwardly therefrom, the tongues having lateral serrations of negative undercut configuration extending along at least one face thereof corresponding to said at least one groove face, and the tongues and the serrations thereof being of selected size and configuration for closely fitting within the associated grooves and to the serrations of said associated grooves.
Claim 2
Dependent Claim
142 words
A bicycle pedal system comprising: a pedal formed of rigid material and being adapted for mounting along a rotational axis thereof to a bicycle and having a pair of lateral grooves therein, each groove being defined by two faces oriented in a V-shaped configuration and having lateral serrations of negative undercut configuration in at least one face thereof; and a shoe clip formed of rigid somewhat flexible material and being adapted for attachment to a shoe and having a pair of lateral tongues of generally triangular configuration extending downwardly therefrom, the tongues having lateral serrations of negative undercut configuration extending along at least one face thereof corresponding to said at least one groove face, and the tongues and the serrations thereof being of selected size and configuration for closely fitting within the associated grooves and to the serrations of said associated grooves.
Claim 3
Dependent Claim
17 words
The bicycle pedal system of claim 1, wherein the shoe clip is formed of thermoplastic polymer material.
Claim 4
Dependent Claim
32 words
The bicycle pedal system of claim 1, wherein the shoe clip is formed of thermoplastic polymer material and the pedal is formed of material selected from aluminum, titanium, polymer and filled polymer.
Claim 5
Dependent Claim
40 words
The bicycle pedal system of claim 1, wherein the serrations are undercut such that the upper surface thereof extends downwardly at an angle of about 15° relative to a plane intersecting the planes of said faces at approximately equal angles.
