Title
(EN) KEY AND DISC TUMBLER CYLINDER LOCK
(FR) SERRURE À CYLINDRE À PAILLETTES ET CLEF
Abstract
(EN)
The invention relates to a disc tumbler cylinder lock and a key for it. The key according to the invention comprises a groove (6) that is transverse to the key shank (2). The groove comprises a bottom section (6A) and side sections (6B) that are transverse to the bottom section between the bottom section and the outer surface (2A) of the key shank. The bottom section of the groove is the key's main driving surface used to transfer turning force to the disc tumbler cylinder lock. This reduces wear on the O-surfaces of the key because the O-surfaces do not transfer the majority or any of the key turning force to the disc tumbler cylinder lock.
(FR)
L'invention porte sur une serrure à cylindre à paillettes et sur une clef associée. La clef de l'invention comprend une rainure (6) transversale par rapport à la tige de la clef (2). La rainure comprend une section inférieure (6A) et des sections latérales (6B) qui sont transversales par rapport à la section inférieure entre la section inférieure et la surface extérieure (2A) de la tige de la clef. La section inférieure de la rainure constitue la principale surface d'entraînement de la clef utilisée pour transférer la force de rotation à la serrure à cylindre à paillettes. L'invention permet de réduire l'usure subie par les surfaces d'extrémité de la clef étant donné que ces dernières ne transfèrent qu'une partie insignifiante, voire nulle, de la force de rotation de la clef à la serrure à cylindre à paillettes.
