Definitions

  • This invention relates to cylinder locks and keys therefor.
  • a plurality of tumblers are arranged to be moved radially between a released position and a locked position as a result of engagement by cam surfaces on the key when the key is rotated in the lock.
  • a lock and key set comprising a cylinder lock having a plurality of tumblers arranged to be moved radially between a released position and a locked position, and a key comprising a handle, an axially extending bit adapted to be inserted into the lock, a plurality of cam surfaces formed on the shaft for moving the tumblers between the locked and released positions upon rotation of the key relative to the cylinder lock, and stop means for positioning the key axially within the cylinder lock with the cams in registry with the tumblers, characterised in that the cams are arranged on the key in two sets which are axially off-set from each other, and the stop means are arranged to position one set of cams in registry with the tumblers when the key is inserted into the lock in a first orientation and to position the other set of cams in registry with the tumblers when the key is inserted into the lock in a second orientation rotationally spaced from the first orientation by 180 0 .
  • the key may be inserted into the lock in either of two possible angular orientations.
  • the invention also includes a key for a cylinder lock having a plurality of tumblers arranged to be moved radially between a released position and a locked position, the key comprising a handle and an axially extending bit adapted to be inserted into the lock, a plurality of cam surfaces formed on the shaft and adapted to the cam surfaces to move the tumblers between the locked and released position upon rotation of the key relative to the cylinder lock, and stop means for positioning the key axially with the cylinder lock with the came in registry with the tumblers, characterised in that the cams are arranged on the key in two sets which are axially off-set from each other, and the stop means are arranged to position one set of cams in registry with the tumblers when the key is inserted into the lock in a first orientation, and to position theother set of cams in registry with the tumblers when the key is inserted into the lock in a second orientation rotationally spaced from the first orientation by 180°.
  • the invention also includes a cylinder lock comprising a plurality of tumblers arranged to be moved radially between a released position and a locked position by rotational movement of a key relative to the cylinder lock, and stop means for positioning the key axially within the cylinder lock with the cams in registry with the tumblers, characterised in that the stop means are arranged to position the key in two different positions axially off-set from each other according to whether the key is inserted into the lock in a first orientation or a second orientation rotationally spaced therefrom by 1 80 0 .
  • the stop means may be provided by appropriate shaping of either the key or the lock or both.
  • the stop means may comprise a shoulder on the key adjacent handle, or a shaped abutment surface on the end of the bit.
  • the stop means may comprise/shaped abutment on the cylinder lock, such as a face within the cylinder of the lock or a outer wall of the cylinder lock.
  • a cylinder lock 1 comprises a two- part cylindrical housing 2,2, and a barrel 3 rotatably mounted in the housing.
  • the barrel 3 is hollow and carries a stack of tumblers 6 spaced from each other by spacers 7.
  • Each tumbler and spacer has an aperture through which the axially extending bit 10 of a key 11 can be inserted.
  • the apertures in the spacers 7 do not interfere with the rotation of the key bit 10 in the barrel 3, but the apertures 8 of the tumblers 6 are shaped to engage cam surfaces 12 on the key bit 10.
  • the cam surfaces 12 are arranged on the key bit 10 in two sets as indicated at 12a and 12b.
  • the axial spacings between the cam surfaces of each set is identical and corresponds to the spacings between the tumblers 6. However the two sets of cams are axially off-set from each other.
  • the cams 12 remote from the handle of the key have end faces which cooperate with a corresponding abutment (not shown) within the barrel 3 to position the key axially within the barrel 3. Since the two sets of cams 12a, 12b are axially offset from each other, the axial position of the key within the barrel 3 is different, according to whether the key is inserted into the lock in the orientation illustrated in the drawing, or in an orientation spaced therefore by rotation through 180° about the axis 1 8 of the key, as indicated by the arrow 20.
  • initial rotation of the key causes the tumblers 6 to withdraw from their locking positions (illustrated in the drawings). Thereafter the barrel 3 rotates with the key to operate a component (not shown) such as a door latch mechanism attached thereto.
  • a component such as a door latch mechanism attached thereto. In using the key therefore, the driver does not have to concern his or herself with the orientation of the key relative to the lock.
