MÉCANISME DE LEVIER PERMETTANT DE CONVERTIR UN MOUVEMENT LINÉAIRE EN UN MOUVEMENT ROTATIF

摘要

A lever mechanism (10) for converting a motion from linear to rotary, comprising a guiding bar (55), a slider (60) which slides along the guiding bar (55) and acts on a lever (15) by means of a pivot (65); the lever (15) comprising a cylindrical element (30) and a pair of slot links (20, 25); each slot link (20, 25) comprises a guiding slot (35); the mechanism further comprises: – at least one sliding block (140) which is interposed between the pivot (65) and an internal surface (350) of at least one of the guiding slots (35), the sliding block (140) being able to slide within the at least one guiding slot (35) and – at least two friction elements (160, 161), which are adapted to reduce the friction between the sliding block (140) and the internal surface (350) of the at least one guiding slot (35); the two friction elements (160, 61) are arranged between the sliding block (140) and the internal surface (350) of the at least one guiding slot (35).
