the mechanism has plate wts. in the form of a counter wt. (1) suspended on a cable (3) connected to a lever (6) via a system (2) of pulleys. The counter wt. has only a single flat wt. with which the cable is connected via pulleys to an arm (7) of the lever in the vicinity of its axis of rotation (5). A clamp slider (8) with rollers (9) is mounted so as to slide on the arm. The cable runs between these rollers. A regulating system (10) for setting the angle between both arms of the lever is built into the rotation axis. |
