Definitions

  • the invention relates to a cylinder lock comprising a stationary cylinder housing and a rotatable cylinder enclosing a number of locking disks turnable by means of the key of the lock, and between the locking disks intermediate disks, the turning of which with respect to the cylinder is prevented, and a locking bar locking the cylinder with respect to the cylinder housing, situated between the outer rim of the locking disks and the stationary cylinder housing and being movable from its locking position into a cylinder releasing position in a channel formed by recesses in the rim of the locking disks when aligned in a certain position.
  • the invention is characterized in that the form of the key of the lock and its turning angle when moving the locking disks from their initial position to the cylinder releasing position, are in a way known per se so determined that the angle covered by the cross-section of the key is smaller than 360, preferably only 270, the position of the locking bar being so chosen that it is situated in the sector left uncovered by the cross-section of the key, and that in the intermediate disk its central key receiving opening is in the said sector smaller than a full circle.
  • the central opening of the intermediate disk has the form of a segment of a circle, the central angle of the segment being preferably about 270.
  • FIG. 1 shows a cross-section of a lock according to the invention.
  • FIG. 2 shows an intermediate disk for a lock according to the invention.
  • FIG. 1 indicates a stationary cylinder housing, 2 a turnable cylinder, 3 a locking bar, 4 a locking disk and 5 a key.
  • this cross-section of the key has a semiciricular form, this cross-section will cover an angle of 270 during the said turning movement. Hence a right angle sector will remain uncovered and the locking bar 3 is situated in the middle of this sector.
  • the recesses 8 in the locking disks are aligned and form a channel at the locking bar 3, and the locking bar can move from a groove 9 made in the cylinder housing 1 to the channel formed by the recesses 8 of the locking disks.
  • the entire set of locking disks including the intermediate disks turns, bringing with it the cylinder.
  • the turning movement of the cylinder influences, for instance, the lock bolt of a door lock or any other member connected to the cylinder lock in question.
  • FIG. 2 shows an intermediate disk 10 having in its bottom part a protrusion 11 extending over a sector of about 90, which protrusion fits into the opening 7 of the cylinder and prevents the turning of the intermediate disks relative to the cylinder.
  • the central opening 12 of the intermediate disk has the form of a segment of a circle and the central angle of the segment is about 270".
  • the intermediate disk there is a recess 13 which corresponds to the recesses 8 of the locking disks.
  • the weak portion 14 will be broader than in intermediate disks previously known having a circular central opening.
  • a cylinder lock comprising a stationary cylinder housing, a rotatable cylinder in said housing, a plurality of locking disks enclosed by said housing and turnable by means of a key for the operation of said lock, intermediate disks disposed between said locking disks in a non-turning relationship with respect to said cylinder, a locking bar located between the outer surface of said locking disks and said housing, said intermediate disks being each provided with a recess for receiving said lock ing bar during the operation of the lock, said intermediate disks having a central opening for said key, said key having a cross-section and turning through an angle during the operation of the lock so determined as to leave a sector of said intermediate disks untraversed by said References Cited cross-section of the key, said recess of each of the inter- T mediate disks being situated Within said untraversed sec- FOREIGN PATENTS tor, said central opening being non-circular and having 25,706 12/1952 i in said untraversed sector a smaller radial extent than
  • a lock a ccording to claim 2, in which the central 10 angle of said segment is about 270.
