Abstract

L'invention concerne un assemblage pliable et son dispositif de verrouillage, ledit assemblage pliable comprenant principalement une première partie pliable (1), une seconde partie pliable (2), un bloc de verrouillage (5) et un élément de manipulation. Le bloc de verrouillage, ayant une surface inclinée, est disposé au niveau de la position de verrouillage des deux parties pliables qui sont reliées par un axe à charnière. Le bloc de verrouillage est relié à l'extérieur de la seconde partie pliable par une charnière. Une surface inclinée est positionnée sur la première partie pliable pour s'engager avec le bloc de verrouillage. Ce dernier peut être entraîné par l'élément de manipulation et un élément élastique de façon à verrouiller ou libérer les deux parties pliables. Le dispositif selon l'invention est de structure simple, et d'utilisation pratique et sûre.
