Definitions

  • ABSTRACT A cylinder lock which comprises a core having a key slot. A key is to be inserted in the key slot and includes wide faces for receiving recesses therein. Tumblers are provided in the core adjusted by the key with the recesses.
  • a housing receives the core and includes a flange extending radially to the core and has bores.
  • the key slot is disposed in symmetric cross position to the flange.
  • At least two rows of the tumblers are arranged in the flange.
  • the tumblers have a non-round cross-section and sit non-rotatably in the bores of the vflange. 1
  • the present invention relates to a cylinder lock, in general, and to such cylinder lock with a key to be inserted into a key slot of a cone, which coordinates tumblers with its recesses provided on the wide faces of the key.
  • Round cylinder locks are known already, wherein rows of pin tumblers are provided on one wide side of a key slot, in order to realize so called fiat key constructions.
  • Such cylinder locks have, compared with the conventional locks a higher closing combination number, however, they are comparatively easy to open by pick-locks and auxiliary tools.
  • the present invention has the advantage, that the separating gap of the tumbler pins is adjusted to the curved configuration of the jacket face of the core.
  • the key slot is closed on the one narrow side by a filling member, the outer bent side face of which supports itself on the wall of the bore.
  • the filling member forms a rib, projecting into the key slot, which rib enters formfittingly the groove, projecting beyond the point range of the key.
  • one or a plurality of tumbleripins disposed on-the flange side is formed of more than two parts, such, that two separating gaps, superposed relativeto each other and adjustable into the slide gap of-the core areprovided.
  • an advantageousfeature of the present invention resides in the fact, that the separating gap of each pair of tumbler pins is adjusted by a curved formation of the end faces of the slide'gap of the core.
  • a further advantage is a variation realized, in accordance with the present invention, such, that a rear end section of the key slot free of tumbler pins, is crosssection profiled by projections extending only over the length of this end section.
  • the projections are formed by ribs of a filling member inserted into the cylinder core, the bent narrow faces of the filling member are disposed in the core slide gap.
  • the projections are formed by radially directed screws in the core, which projections have preferably a set-off pin projection extending into the lock slot.
  • a further still different advantageous embodiment resides in the fact, that, in accordance withthe present invention, theprojections areformed as keys of a comb inserted into a cross slot .of the core with a sector shaped cross-section.
  • a cross-section profile of the end section of the key slot is favorably realized by projections entering the latter, which projections perform a double function..Firstly of all, they limit the insertion movement of the key and, on the otherhand, only the key can be inserted, the grooves of which open towards the key end complement the projections disposed at the inner side end of thekey slot by a form filling entrance. Furthermore,
  • the closing combination is additionally increased by the variation of the length and form of the projections. Due to
  • a filling member equipped with ribs and filling out the total key slot cross-section isarranged, an advantageous structural form is obtained.
  • the filling member is easily insertable and permits a fast exchangeability against another filling member equipped with ribs.
  • Another advantageous configuration has radially directed screws in the core, which screws project with their pin projections into the key slot.
  • the projections are formed by teeth of the sector-shaped comb. The latter is to be produced with saving of costs as a punching part.
  • here is also a fast exchangeability against another comb equipped with teeth possible.
  • a further solution resides, in accordance with the present invention, in the fact, that the abutment limit for the insertion movement of the key is obtained by a form-filling entrance of a rib disposed at the inside end of the key slot into a corresponding groove of the key displaceable locking member of the cylinder core.
  • a positive feature of the present invention resides in the fact, that the locking member carrying the rib is displaceable from the locking position into a releasing 00 position and beyond the latter again in a locking position.
  • the filling member has a rib.
  • a particularly sensitive formation save against sensing is in a most favorable manner realized by a groove widened towards the then the cylinder core can be rotated.
  • a groove of a false key which is dimensional for instance too short, displaces the locking member over the releasing position again into a locking position; a groove of the key dimensioned too long, however, brings about, that the locking member is likewise not put in a releasing position.
