Abstract:
An actuation lever assembly for the actuation of an associated element, comprising:an actuation lever having a bore defined therethrough;an eccentric element having an eccentric circumferential surface and a threaded bore defined therein;a bearing pin having a threaded portion at one end thereof for threaded engagement within said threaded bore of said eccentric element, the other end of said bearing pin having engagement means for receiving a tool by which said bearing pin may be rotated, and a shank portion rotatably supported and axially movable within said bore of said actuation lever, rotation of said bearing pin with respect to said actuation lever causing the eccentric element to be rotated so as to change said disposition of said circumferential surface of said eccentric element with respect to the associated element to be actuated; andfirst and second rotation limiting means respectively provided upon said eccentric element and said actuation lever such that when said bearing pin is disposed at a first axial position with respect to said actuation lever, said first and second rotation limiting means of said eccentric element and the actuation lever are engaged with each other so as to prevent said eccentric element from rotating with respect to said actuation lever, while when said bearing pin is disposed at a second axial position, axially spaced from said first axial position, with respect to said actuation lever, said first and second rotation limiting means of said eccentric element and said actuation lever are disengaged from each other so as to permit said eccentric element to rotate with respect to said actuation lever.
