A compliant, bistable operating mechanism (10) has a plurality of coupled segments (14) including at least two rigid segments (22, 26, 30) and at least one relatively flexible, resilient segment (34). The adjacent rigid segments are coupled by flexible joints (52) or pin joints (54). The flexible, resilient segment is coupled to adjacent rigid segments either fixedly or by pin joints. There are at least four pin joints, flexible joints, and/or flexible and resilient segments. The flexible, resilient segment resists movement and biases the plural rigid segments. The coupled segments move between first and second stable equilibrium positions (70, 72). The segments have a pseudo-rigid-body model resembling a four-bar linkage. The segments and flexible joints may be integrally formed. First and second electrical contacts (90, 92) are coupled to the segments to form an electrical connection as the segments move to one of the positions.
L'invention concerne un mécanisme (10) de commande bistable compatible. Ledit mécanisme a plusieurs segments (14) couplés comprenant au moins deux segments rigides (22, 26, 30) et au moins un segment élastique (34), relativement souple. Les segments rigides adjacents sont couplés par des articulations souples (52) ou des articulations à tourillon (54). Le segment élastique souple est couplé à des segments rigides adjacents d'une manière fixe ou par des articulations à tourillon. Il y a au moins quatre articulations à tourillon, articulations souples et/ou segments élastiques et souples. Les segments couplés se déplacent entre les première et seconde positions (70, 72) d'équilibre stable. Les segments ont un modèle de corps pseudo rigide ressemblant à un quadrilatère articulé. Les segments et les articulations souples peuvent être formés d'une pièce. Les premier et second contacts électriques (90, 92) sont couplés aux segments de façon à former une liaison électrique lorsque les segments se déplacent vers l'une des positions.
