Patent ID: 8075065

Claim:
A quick-release system for a quick-release device for a cycle, such device including a skewer extending in an axial direction and an end support element mounted at a first end of the skewer adapted to be supported by a first tightening support surface of the cycle, said quick-release system comprising: a tightening sub-assembly including a rotatable member and a support surface, the support surface being configured and arranged to be supported by a second support surface of the cycle; an actuation sub-assembly including a movable actuating mechanism, capable of axial rotation around said skewer, and configured and arranged to transmit a tightening torque to the rotatable member of the tightening sub-assembly when the device is being tightened; a tightening torque limiting mechanism to limit torque transmitted by the actuation sub-assembly to the tightening sub-assembly; said tightening torque limiting mechanism forming a disengageable connection interface configured and arranged to limit torque transmitted by the actuation sub-assembly to the tightening sub-assembly to a limiting value of the torque or to a predefined range of tightening torque values; said disengageable connection interface comprising respective mutually engageable surfaces of the tightening sub-assembly and the actuation sub-assembly.
