  • a reset mechanism is provided for rotating all disc members into a reset position.
  • the combination lock is provided with a reset function which is performed by depressing the shackle, which entails rotation of a reset component.
  • the reset cross 14 is located in the center of the mechanism which is intended to reset the CAMs 15.

  • the shackle is the source for the force supplied for the crosses' rotation.
  • a combination lock comprising a housing; a locking bolt with at least one end segment extending into the housing; a latch accommodated within the housing and selectively engageable with the locking bolt, and configured for displacing between a latched state in which the locking bolt is in secure engagement with the latch, defining 20 a locked state of the lock, and an unlatched state in which the locking bolt is free to disengage therefrom, defining an open state of the lock; and a combination mechanism accommodated within the housing and comprising:
  • a locking assembly engaged with a manipulator configured for introducing a combination thereto by planar displacement of the 25 manipulator;
  • a locking member configured for displacing between an engaged state with respect to the locking assembly and a disengaged state with respect to the locking assembly
  • a reset member configured for resetting the locking assembly for 30 introduction of another combination
  • displacement of the latch to the latched state is achieved only when the locking member is in its disengaged position, and wherein said manipulator is in selective engagement with both the locking member and the reset member, allowing both disengagement of the locking member and resetting of the mechanism by the reset member, by the manipulator.

  • any attempt to rotate either of the locking member and the reset member from their initial orientation is performed by a force against the biasing force of the biasing element, after which, once said force is no longer applied, is the members are urged to return to their initial orientation owing to the biasing element.

  • Examples of applications can be locks for bags, safes etc. Nonetheless, the present combination lock can still be used for shackle locks such as: padlocks, bicycle locks, U-lock, etc.
  • such a design enables, contrary to known combination locks, a more robust design since attempts to breach the lock by pulling on the shackle will not harm the lock's mechanism, as the force will only be directed towards the latch.
