Abstract

Cette invention concerne un cadenas ayant un verrou en forme de U inversé et possédant deux modes de verrouillage. Dans un de ces modes, le verrouillage se fait uniquement en poussant le verrou dans un corps à l'état déverrouillé où une clé est extraite dudit corps. Dans l'autre mode, le verrouillage se fait non seulement en poussant le verrou dans le corps lorsque la clé est insérée dans ce dernier et que le cadenas est déverrouillé, mais aussi en tournant la clé une fois le verrou poussé dans le corps. La tige la plus longue du verrou en forme de U inversé pénètre dans le corps du cadenas de manière à ce qu'elle puisse coulisser dans ledit corps mais ne puisse s'en dissocier. Le cadenas comprend des renfoncements pratiqués dans le verrou, ainsi qu'une came de type colonne comportant des billes de verrouillage, des renfoncements et une protubérance dirigée vers un cylindre interne afin de s'y fixer. Le cylindre interne comporte également une protubérance dirigée vers la came afin de s'y fixer, la protubérance de la came entrant en interaction avec celle du cylindre interne. Un ressort hélicoïdal est situé sur la périphérie externe des parties des protubérances qui entrent en contact. Une extrémité de ce ressort est montée sur la came tandis que l'autre extrémité est montée sur le cylindre interne. Le fait de tourner la came va faire se déplacer les billes de verrouillage entre les renfoncements du verrou et les renfoncements de la came de manière à assurer le verrouillage ou le déverrouillage.
