Patent ID: 7392967

Claim:
A clamp comprising: a flexible base comprising a first pivot at one end, a second pivot at the other end, a third pivot below the second pivot, and a staged tunnel through its center; a urging member comprising a neck securely fitted in the tunnel, and a urging surface; a bifurcation pivotably secured to the first pivot and comprising two arms and a bar interconnected the arms thereof; a fastening member having the other end pivotably secured to the second pivot and comprising a series of pawls at the other end, a transverse projection at one end, a urging section interconnected the pawls and the projection, a tunnel member projected from the urging section and being perpendicular thereto, and a toothed section formed on the tunnel member; a universal member comprising a hollow cylinder secured to the fastening member, a gear formed at the other end of the cylinder and meshed with the toothed section, and a disc projected from an outer surface of the cylinder, the disc including a hollow center having a plurality of cavities formed around; a seat comprising a U-shaped member formed on one surface with the disc being fastened therein, an elliptic member formed in the U-shaped member and adapted to fit between any two opposite ones of the cavities, and a mounting member formed on the other opposite surface and adapted to releasably secure to a light; and an elongate flexible member having one end pivotably secured to the third pivot and comprising a loop and a ratchet section having a series of teeth extended from a portion proximate the loop to the other open end; whereby wrapping the flexible member around a seat post of a bicycle by inserting the flexible member through a space between the bar and the first pivot, a space between the second and third pivots, and the loop, pivoting the fastening member toward the seat until one of the pawls catches and holds one of the teeth of the ratchet section and the urging section presses on the base to urge the urging surface against the seat post, and pivoting the bifurcation to press the bar onto the projection will fasten the clamp onto the seat post.
