Patent
CA 2373115
A lock for a door (10) has a casing (11), a blot (55), a pivoted operating handle (36) operable to retract the bolt, and lock means comprising a lock cylinder (39). The lock cylinder (39) is secured to the housing by a screw (38g) covered by a rose (110) around said part of the housing, the rose being secured in place by fixing screws (38h) which can only be accessed upon removal of the casing assembly from the door and with the bolt in a retracted position. In this state the shank of the screwdriver to undo each fix-ing screw can easily be passed through respective aligned openings in a cover plate (12) of the housing assembly, the bolt (55), and the housing (38), thereby allowing removal of the rose and subsequent replacement of the cylinder (39) without the need to remove com-ponents of the door lock itself.
L'invention concerne un verrou de porte (10) comprenant une plaque (11), un pêne (55), une poignée (36) fonctionnant par rotation pour rétracter ledit pêne, et des moyens de verrouillage comprenant un barillet (39). Ledit barillet (39) est fixé à un logement à l'aide d'une vis (38g) recouverte d'une rosette (110) placée autour de la partie de logement, ladite rosette étant maintenue en place à l'aide de vis de fixation (38h) auxquelles on peut accéder uniquement en retirant l'ensemble de plaque de porte, le pêne étant en position rétractée. Dans cette position, la tige d'un tournevis peut facilement traverser les ouvertures respectivement alignées de la plaque de couverture, le pêne et le logement permettant le retrait de la rosette et le remplacement ultérieur du barillet (39) sans avoir besoin de retirer les composants du verrou de la porte.
