Therefore, when pushing the inner cylinder 128, it is only necessary to push the key case 135 together with the mechanical key 81. From the key case 135 to the inner cylinder 128 via the shutter mechanism 104, a pressing force can also be applied to the inner cylinder 128. Therefore, the operability when pushing the inner cylinder 128 can be improved.

Projecting from the rotating member 107 and forming a part of the rotating member 107 on the side that operates the shutter plate 108 from the open position to the closed position when the magnet lock 105 is unlocked. Since it is formed in a shape that can be gripped for manual operation of 107, when the key case 135 is removed from the fitting recess 157 with the shutter plate 108 open at the off position P2, the protrusion 158 is gripped. Thus, by rotating, the shutter plate 108 can be moved from the open position to the closed position, and the operation of re-fitting the key case 135 to the fitting recess 157 is not necessary.
  • one end of the key case 135 is pivotally supported so that the key unit 135 is slidably held on the other end of the lever 142 accommodated in the key case 135.

Since they are connected, the amount of slide operation of the operation knob 147 can be reduced, and the operability can be improved.
  • the mechanical key 81 is held in the key case 1 35 so that it can slide along the central axis C of the key case 135 formed long in the longitudinal direction of the mechanical key 81. Since the operation knob 147 is arranged between the pivotal support to the key case 135 at one end of the lever 142 and the central axis C, the mechanical key 81 can be slid according to the rotation of the lever 142. However, the mechanical key 81 can be arranged on the central axis C of the key case 135.
  • the lever 142 is connected to the mechanical key 81 on the opposite side of the pivot with respect to the central axis C, the connecting portion of the operation knob 147 to the lever 142 and the lever 142 to the mechanical-key 81
  • the sliding distance of the mechanical key 81 can be set larger than the sliding distance of the operation knob 147.

Abstract

La présente invention concerne un dispositif de protection d'une serrure à barillet capable de commuter entre un état où une clef mécanique peut être inséré dans un trou de serrure fourni par un barillet intérieur et un état où la clef mécanique ne peut pas être insérée dans le trou de serrure lorsqu'une fermeture magnétique destinée à être ouverte selon l'approche d'un aimant est ouverte, un mécanisme de volet (26), qui possède un trou d'insertion (38) pour admettre l'insertion d'une clef mécanique (15) dans un trou de serrure (16), un élément rotatif (27) qui tourne de façon coaxiale avec l'axe de rotation d'un barillet intérieur (13) selon l'opération de rotation lors d'une ouverture d'une fermeture magnétique (35), et une plaque de volet (28) enclenchée avec et reliée à l'élément rotatif (27) afin de se déplacer entre une position ouverte pour ouvrir le trou d'insertion (38) selon la rotation de l'élément rotatif (27) et une position fermée pour fermer complètement le trou d'insertion (38), étant disposé dans un corps de barillet (11). En conséquence, il est possible de fermer complètement un trou de serrure de barillet intérieur et de réaliser le mécanisme de volet pour qu'il soit compact.
