Abstract

La présente invention concerne une charnière et un dispositif de réfrigération doté de celle-ci. La charnière comprend un siège de charnière fixe, un siège de charnière mobile, un élément de liaison, un arbre mobile et un élément élastique. L'élément de liaison est relié rotatif à l'arbre mobile et au siège de charnière mobile. L'arbre mobile est relié à une rainure de limitation formée dans le siège de charnière fixe et peut se déplacer le long de la rainure de limitation. L'élément élastique est relié à l'arbre mobile et peut se déplacer le long de la rainure de limitation. La charnière comprend en outre un élément de verrouillage utilisé pour fixer l'élément élastique au siège de charnière fixe. L'élément de verrouillage est assemblé de manière amovible sur le siège de charnière fixe.
