Patent ID: 8727436

Claim:
A seat clamp assembly for securing a bicycle seat to a bicycle frame, the assembly comprising: a body defining a vertical plane; a first member disposed on a first side of the body, the first member having a curved surface defining a first pivot axis which is oriented parallel to the vertical plane; a second member disposed on an opposed second side of the body, the second member having a curved surface defining a second pivot axis which is oriented parallel to the vertical plane; a third member having a curved surface mating against the curved surface of the first member so that the third member is pivotable about the first pivot axis to provide for vertical displacement of a clamping portion of the third member; a fourth member having a curved surface mating against the curved surface of the second member so that the fourth member is pivotable about the second pivot axis to provide for vertical displacement of a clamping portion of the fourth member; a fastening system extending through the aperture of the body for fixing relative positions of the first, second, third and fourth members together upon tightening of the fastening system; wherein the third and fourth members are pivotally displaced upon tightening of the fastening system, and the first and second members along with the clamping portions of the third and fourth members produce a vertical clamping force applied to rails of the bicycle seat between the first and second members and the claming portions of the third and fourth members.
