DISPOSITIF D'ACTIONNEMENT AVEC ELEMENT D'ENTRAINEMENT ACTIONNE PAR REPTATION

摘要

The device (1) has an actuation element (3) whose fixed and moving parts (31, 32) respectively comprise a crawling surface (311) and a movable blade (321). A length of the blade is selected such that a free end (3211) of the blade comes in contact with the crawling surface when a stress is applied between the blade and the crawling surface. A contact area between the blade and the crawling surface is longitudinally delimited by the free end and a crawling face (3213) by increasing propagation of the crawling face along the blade according to a direction to drive a drive element (2). An independent claim is also included for a method for assembling an actuation device.
