Title (EN) LEVER MECHANISM FOR CONVERTING A MOTION FROM LINEAR TO ROTARY
(FR) MÉCANISME DE LEVIER PERMETTANT DE CONVERTIR UN MOUVEMENT LINÉAIRE EN UN MOUVEMENT ROTATIF
Abstract:
(EN) 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).
(FR) La présente invention concerne un mécanisme de levier (10) permettant de convertir un mouvement linéaire en un mouvement rotatif, comprenant une barre de guidage (55), un coulisseau (60) qui coulisse le long de la barre de guidage (55) et agit sur un levier (15) au moyen d'un pivot (65) ; le levier (15) comprenant un élément cylindrique (30) et une paire de liaisons à fente (20, 25) ; chaque liaison à fente (20, 25) comprend une fente de guidage (35) ; le mécanisme comprend en outre : – au moins un bloc coulissant (140) qui est intercalé entre le pivot (65) et une surface interne (350) d'au moins une des fentes de guidage (35), le bloc coulissant (140) pouvant coulisser à l'intérieur de la ou des fentes de guidage (35) et – au moins deux éléments de frottement (160, 161), qui sont conçus pour réduire le frottement entre le bloc coulissant (140) et la surface interne (350) de la ou des fentes de guidage (35) ; les deux éléments de frottement (160, 161) sont agencés entre le bloc coulissant (140) et la surface interne (350) de la ou des fentes de guidage (35).
