Definitions

  • the invention relates to a flat key for a cylinder lock with a coded surface running along the longitudinal extension of the flat key, control points being provided for scanning on the surface at scanning positions, which are connected by a control groove, and wherein coding features are provided at the control points for interrogation in the cylinder lock ,

Abstract

L'invention concerne une clé plate (1) pour une serrure cylindrique, comprenant au moins une surface codée (2) qui s'étend le long de la projection longitudinale de la clé plate (1). Des points de commande (3, 3', 3'') se trouvent sur la surface (2) en des positions de palpage (5) en vue de réaliser le codage, lesquels sont reliés par une rainure de commande (6), et des caractéristiques de codage servant à l'interrogation dans la serrure cylindrique se trouvent au niveau des points de commande (3, 3', 3''). La caractéristique de codage à un premier point de commande (3') forme, avec le plan longitudinal central (8) de la clé plate (1), un angle différent de celui de la caractéristique de codage à un deuxième point de commande (3''). L'invention concerne en outre une serrure cylindrique et un système composé d'une clé plate et d'une serrure cylindrique.
