Abstract
Abstract A device for providing a positive pushing or pulling connection between a bicycle pedal and the shoe worn by the cyclist, which includes a cylindrically projecting assembly to be attached to the pedal and a cylindrically recessed assembly to be fitted into the sole of the shoe. The recessed assembly is provided with radially inwardly directed lugs which can be received into a series of peripheral L-shaped slots in the assembly attached to the pedal so that by partial rotation of the foot a bayonet-type connection is made between the cyclist shoe and the pedal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A device for providing a positive pushing or pulling connection between a bicycle pedal and the shoe worn by the cyclist, said device comprising a cylindrical block a plate for supporting said cylindrical block with its cylindrical surface and one end surface exposed means for removably connecting said support plate to the pedal an open ended cylindrical housing adapted to axially receive said cylindrical block, said housing being disposed in the thickness of the sole of the cyclist's shoe, radially inwardly extending lugs fast with the internal wall of said housing circumferentially arranged recesses provided on the exposed surfaces of said block and adapted to axially receive said lugs, said recesses being L shaped in radial cross section to provide a bayonet type locking engagement when the lugs are angularly displaced after being axially received.
Claim 2
Independent Claim
135 words
A device for providing a positive pushing or pulling connection between a bicycle pedal and the shoe worn by the cyclist, said device comprising a cylindrical block a plate for supporting said cylindrical block with its cylindrical surface and one end surface exposed means for removably connecting said support plate to the pedal an open ended cylindrical housing adapted to axially receive said cylindrical block, said housing being disposed in the thickness of the sole of the cyclist's shoe, radially inwardly extending lugs fast with the internal wall of said housing circumferentially arranged recesses provided on the exposed surfaces of said block and adapted to axially receive said lugs, said recesses being L shaped in radial cross section to provide a bayonet type locking engagement when the lugs are angularly displaced after being axially received.
Claim 3
Dependent Claim
110 words
The device of claim 1, wherein the plate has a cross section in the form of an upturned U, the upper part of the U being flat for supporting the block, the downwardly directed arms of the U being disposed parallel and against the long sides of the pedal for adjustable positioning with respect to the long sides of the pedal, the arms of the U being connected to said long sides of the pedal by a set of bolts, said bolts passing through slots provided one of the elements to be assembled, thus enabling the respective positioning of the plate and the sides of the pedal to be adjusted.
Claim 4
Dependent Claim
59 words
The device of claim 2, wherein the block is fixed on the upper part of the U-shaped plate by a set of bolts passing through said block and through said upper part of the plate, and wherein arcuate slots are provided for the bolts, thus allowing the respective angular positioning of said plate and said block to be adjusted.
Claim 5
Dependent Claim
109 words
The device of claim 1, wherein the block comprises two generally circular, superposed, coaxial plates, having the same diameter; the first plate constituting the body of the block having recesses regularly distributed on its periphery; the second plate, which serves as a reinforcing piece, made of metal of high mechanical strength, such as steel, the first plate and also is provided with notches regularly distributed on its periphery, but of smaller area than the recesses in the first plate said notches partially covering said recesses so as to form together L-shaped recesses adapted to receive the lugs, said lugs being of a shape complementary to that of the notches.
Claim 6
Dependent Claim
40 words
The device of claim 1 wherein the housing is fast with a plate outwardly extending from said housing and said plate is connected to the sole of the shoe in the zone surrounding this housing by a set of rivets.
Claim 7
Dependent Claim
72 words
The device of claim 1, wherein the housing comprises a cylindrical portion and a coaxial truncated portion, the small diameter of the truncated portion being equal to that of the cylindrical portion and its larger diameter being located at the base of said housing, thus enabling the penetration of the block in said housing to be guided, the cylindrical portion having a diameter allowing the block to fit with a slight clearance.
