Abstract:
1. A releasably locking device for securing a bicycle component to a bicycle frame having aligned holes comprising: a traction rod configured to pass through said aligned holes of the component and of the bicycle frame, the traction rod having a first end equipped with an abutment widening at one of said aligned holes and a second end having a through hole; and a clamping element comprising: a housing having an abutment surface at the other one of said aligned holes, and two aligned through openings in a side wall thereof; a rotation cam having an eccentric central portion located within the traction rod through hole and two end portions, each end portion having a defined cross section, that can be commanded into synchronous rotation; and a lever-operated manual actuation system comprising a single forked lever having two branches, each of the branches including an engagement portion that is complementarily shaped with the cross section of a respective end portion of the rotation cam and is positively engaged with the respective end portion of the rotation cam for integral rotation of the rotation cam and commanding the end portions of the rotation cam into synchronous rotation to transmit rotation between the lever and the rotation cam, the rotation cam extending between the engagement portions of the branches, the through openings of the housing, and the through hole of the second end of the traction rod, and wherein the lever operated manual actuation system drives the rotation cam between a clamping operating position wherein the traction rod forces the abutment widening and the abutment surface towards each other, and a release position wherein the traction rod forces the abutment widening and the abutment surface apart; wherein the first end portion of the rotation cam is sized to pass through the engagement portion of the second branch and the traction rod through hole and engage the engagement portion of the first branch, and the eccentric central portion of the rotation cam is sized to pass through the engagement portion of the second branch such that the second end portion of the rotation cam engages the engagement portion of the second branch.
