Abstract

La présente invention a pour objet de réaliser un dispositif de verrouillage et une structure de porte qui permettent de réaliser d'importantes économies d'énergie. Un dispositif de verrouillage (1) est de type à auto-maintien et il est pourvu : d'un boîtier (11) ; d'un pêne dormant (10) qui est apte à se déplacer par rapport au boîtier (11) et qui se déplace dans une direction de déplacement prescrite à partir d'une position de référence ; d'un élément de poussée qui pousse le pêne dormant (10) vers la position de référence ; d'un solénoïde (14) qui presse le pêne dormant (10) dans la direction de déplacement en s'opposant à la poussée de l'élément de poussée lorsqu'il est mis sous tension ; et un mécanisme de restriction (18) qui limite ou libère la restriction du pêne dormant (10) à chaque fois qu'une force de pressage agit sur celui-ci à partir du solénoïde (14). Le mécanisme de restriction (18) du dispositif de verrouillage (1) est un mécanisme qui utilise une came telle qu'une came en forme de cœur qui utilise une rainure de came (1800) et un élément de broche (181).
