Bicycle pedal and shoe connector

Claim 2

A connection between a pedal of a bicycle and a shoe, comprising: a first coupling member mounted on the underside of the shoe, a second coupling member mounted on the pedal for joining with said first coupling member, said first and second coupling members having radially projecting flanges which engageably interfit and interengage after axial engagement followed by a twist of the shoe relative to the pedal which may be released again by a corresponding countermotion, said first coupling member mounted on the underside of said shoe and said coupling member mounted on said pedal further having a circumferential guide surface on an edge between said radially projecting flanges associated with said pedal, for said coupling member mounted on said shoe; and, torque threshold locking means, located between said shoe and said pedal, for permitting interengagement of said shoe with said pedal and for holding the coupled shoe against rotation, in a normal position with respect to the pedal until a torque associated with the counter-motion reaches a certain threshold.

Claim 3

A bicycle racing shoe with a first coupling member for connection with a pedal having a second coupling member, said first coupling member being integrally formed on the outsole of said shoe and comprising a plurality of radially extending flanges and a central centering element for engagement by a corresponding centering element of the pedal the outside of the shoe in an area between said first coupling element and the tip of the shoe, comprises a recess for engagement with a lug on the pedal for forming a catch.

Claim 4

A bicycle racing shoe with a first coupling member for connection with a pedal having a second coupling member, said first coupling member being integrally formed on the outsole of said shoe and comprising a plurality of radially extending flanges and a central centering element for engagement by a corresponding centering element of the pedal the outside of the shoe in an area between said first coupling element and the tip of the shoe, comprises a recess for engagement with a lug on the pedal for forming a catch.

Claim 5

A pedal for connection to a shoe having a first coupling member, the pedal comprising a second coupling member with a plurality of radially extending flanges and a central centering element for engagement with a corresponding centering element of the shoe; a lug spaced from said centering element of said first coupling member for engagement with a recess of the shoe for forming a catch, the lug being a hemispherical head of a screw adjustably screwed into a body of the pedal.

Claim 6

A pedal for connection to a shoe having a first coupling member, the pedal comprising a second coupling member with a plurality of radially extending flanges and a central centering element for engagement with a corresponding centering element of the shoe; a lug spaced from said centering element of said first coupling member for engagement with a recess of the shoe for forming a catch, the lug being a hemispherical head of a screw adjustably screwed into a body of the pedal.

Claim 7

A pedal according to claim 3, wherein the radially extending flanges of the second coupling member are formed on a plate fastened onto the body of the pedal.

Claim 8

A connection between a pedal of a bicycle and a shoe comprising: a first coupling member mounted on the underside of the shoe, a second coupling member mounted on the pedal for joining with said first coupling member, said first and second coupling members having radially projecting flanges which engageably interfit and interengage after axial engagement followed by a twist of the shoe relative to the pedal which may be released again by a corresponding countermotion, said first coupling member mounted on the underside of said shoe of said coupling member mounted on said pedal being constructed so that during axial joining of the coupling members, the coupling members act to center the shoe relative to the pedal, and torque threshold locking device including a lug mounted on said pedal and a recess formed in said shoe, for permitting interengagement of said shoe with said pedal so as to form the coupled shoe, against rotation, in a normal position with respect to the pedal when the lug and the recess engage so as to form a catch effect until a torque associated with the counter motion reaches a certain threshold, said coupling member mounted on said pedal having a flange shaped element extending radially outwardly that can be inserted in a corresponding recess of said flange shaped element carried by said shoe, said coupling member mounted on said pedal having a circumferential guide surface on an edge between said radially projecting flanges associated with said pedel, for said coupling member mounted on said shoe.

Claim 9

A connection between a pedal of a bicycle and a shoe comprising: a first coupling member mounted on the underside of the shoe, a second coupling member mounted on the pedal for joining with said first coupling member, said first and second coupling members having radially projecting flanges which engageably interfit and interengage after axial engagement followed by a twist of the shoe relative to the pedal which may be released again by a corresponding countermotion, said first coupling member mounted on the underside of said shoe of said coupling member mounted on said pedal being constructed so that during axial joining of the coupling members, the coupling members act to center the shoe relative to the pedal, and torque threshold locking device including a lug mounted on said pedal and a recess formed in said shoe, for permitting interengagement of said shoe with said pedal so as to form the coupled shoe, against rotation, in a normal position with respect to the pedal when the lug and the recess engage so as to form a catch effect until a torque associated with the counter motion reaches a certain threshold, said coupling member mounted on said pedal having a flange shaped element extending radially outwardly that can be inserted in a corresponding recess of said flange shaped element carried by said shoe, said coupling member mounted on said pedal having a circumferential guide surface on an edge between said radially projecting flanges associated with said pedel, for said coupling member mounted on said shoe.
