LOCK SYSTEM FOR DOOR KNOB
The invention relates to a lock system comprising a lock cylinder (4), a rotary knob (5, 5') having a greater diameter than the lock cylinder (4) and a lock cylinder sleeve (2). The lock cylinder (4) comprises a driving blade (42) at a first end (18), the driving blade (42) being configured to be rotated around a rotating axis (A), which is parallel and offset (d) relative to a longitudinal axis (L) of the lock cylinder. The rotary knob (5, 5') is connected to the lock cylinder (4) and configured to be coupled to the driving blade (42) for rotating the driving blade (42) upon a positive identification. The lock cylinder sleeve (2) comprises a circular recess (9) for receiving the lock cylinder (4) and at least a part of the rotary knob (5, 5'), whereby the lock cylinder sleeve (2) is configured to abut a surface of a door (50). The lock cylinder sleeve (2) comprises an at least partially asymmetric inner flange (8) extending perpendicular to the axis (A) into the recess (9) forming an opening (7). The opening (7) is configured to receive the lock cylinder (4), which comprises an at least partially asymmetric flange (24) at a second end (23), so that the asymmetric flange (24) abuts the inner flange (8) of the lock cylinder sleeve (2) so that a rotating axis (A') of the rotary knob (5, 5') is congruent with the rotating axis (A) of the driving blade (42). The rotary knob (5, 5'), the lock cylinder (4) and the lock cylinder sleeve (2) can then be clamped to the door (50) and a door lock (56), respectively, from an inner side of the door (50) via screws that engage the first end (18) of the lock cylinder (4) through the door lock (56).
