  • second clutch 104 is temporarily rotationally coupled to cam assembly 24 via first clutch 56. Since the key 116 is fully inserted and is keyed to keyed cylinder plug 100, keyed cylinder plug 100 can now be rotated by rotation of key 116, which in turn rotates cam assembly 24 to retract or throw (i.e., extend) bolt 18 on mortise lock 10.
  • the turn-piece shaft 46 is spring loaded by compression spring 54 in order to allow the key 116 to be fully inserted even when the protruded feature 138 of second clutch 104 is not aligned with the slot feature 92 of first clutch 56 (see Figs. 9-11), i.e., thereby longitudinally displacing first clutch 56 in direction 170 away from keyed cylinder plug 100 and away from the neutral position 98 to a non-neutral position, such as when the turn-piece 42 is at an orientation other than in the vertical direction (position).
  • This displacing of first clutch 56 in direction 170 is facilitated by the longitudinal extent of through-slot 88 and results in a compression of compression spring 54.
  • the keyed cylinder plug 100 can be rotated and eventually the protruded feature 138 of second clutch 104 will self-align with the slot feature 92 of first clutch 56, and once aligned, the protruded feature 138 of second clutch 104 will engage slot feature 92 of first clutch 56 in the axial direction 95 along longitudinal axis 34 by the decompression of compression spring 54, thus returning first clutch 56 to the neutral position 98 illustrated in Figs. 12 and 13.
  • first clutch 56 can rotate independently of keyed cylinder plug 100, so the turn-piece 42 can be turned to activate mortise lock 10, even though keyed cylinder plug 100 remains in a locked condition until the key is reinserted.

Abstract

L'invention porte sur un barillet de serrure à mortaiser qui comprend un ensemble pièce de rotation comprenant une pièce de rotation en prise d'entraînement avec un premier accouplement. Un ensemble barillet à clé comprend un corps de barillet en prise d'entraînement avec un second accouplement. Une première partie de l'ensemble pièce de rotation est reçue dans la première extrémité d'un boîtier, et une seconde partie de l'ensemble barillet à clé est reçue dans la seconde extrémité du boîtier. Une came est positionnée dans la fente de came et montée à rotation. Le barillet de serrure à mortaiser est configuré de telle sorte que la came vient toujours en prise d'entraînement avec le premier accouplement, et que le second accouplement est couplé en entraînement à la came par l'intermédiaire du premier accouplement lorsque la clé est insérée dans l'ensemble barillet à clé.
