Definitions

  • the present invention relates generally to keying systems for cylinder locks and particularly to a keying system that includes a temporary master key, an intermediate key for voiding use of the temporary master key, and an occupant key.
  • each lock having its own key combination.
  • each cylinder lock is generally provided with tumbler pins (in the rotatable tumbler of the lock which has a keyway) and driver pins (positioned in the lock body and alignable with the tumbler pins to a shear line by insertion of a proper key into the keyway).
  • the construction manager Before any apartment is turned over to an occupant, the construction manager generally has a master key that operates all the locks in the building.
  • the present invention seeks to provide an improved keying system that solves the above problems.
  • the keying system includes a temporary master key, an intermediate key for voiding use of the temporary master key, and an occupant key, as is described more in detail hereinbelow.
  • the keying system may be easily manufactured and assembled.
  • a keying system including a cylinder lock including a tumbler having a keyway and tumbler pins, driver pins being disposed in the cylinder lock, a master key element disposed in the cylinder lock that forms together with the tumbler pins and the driver pins a master key combination alignable with a shear line by insertion of a master key into the keyway, the tumbler being rotatable along the shear line, and an intermediate key, which when inserted in the keyway, aligns the tumbler pins, the driver pins and the master key element with the shear line to permit rotation of the tumbler, and displaces the master key element so that the master key element is no longer alignable with the shear line by means of the master key.
  • the intermediate key is adapted to displace the master key element to a position that permits removal of the master key element from the cylinder lock. After removal of the master key element from the cylinder lock, the intermediate key does not align the tumbler pins and the driver pins with the shear line to permit rotation of the tumbler.
  • the master key element may be positioned between the tumbler and at least one of the driver pins, wherein that at least one of the driver pins does not participate in alignment with the shear line upon insertion of the master key into the keyway.
  • the intermediate key may be formed with a recess and the at least one of the driver pins is biased against the master key element by a biasing device, wherein when the intermediate key is inserted in the keyway, the biasing device urges the master key element into the recess.
  • rotation of the intermediate key may move the master key element away from its position between the tumbler and the at least one of the driver pins and permit removal of the master key element from the cylinder lock.
  • a method for master keying including providing a master key that operates a plurality of cylinder locks, each cylinder lock including a tumbler having a keyway and tumbler pins, driver pins being disposed in the cylinder lock, wherein a master key element is disposed in the cylinder lock that forms together with the tumbler pins and the driver pins a master key combination alignable with a shear line by insertion of the master key into the keyway, the tumbler being rotatable along the shear line, and providing an intermediate key, which when inserted in the keyway, aligns the tumbler pins, the driver pins and the master key element with the shear line to permit rotation of the tumbler, and displaces the master key element so that the master key element is no longer alignable with the shear line by means of the master key.
  • the intermediate key may be adapted to displace the master key element to a position that permits removal of the master key element from the cylinder lock, and further including using the intermediate key to remove the master key element from the cylinder lock.
  • the method may further include providing an occupant key, which after removal of the master key element from the cylinder lock, aligns the tumbler pins and the driver pins with the shear line to permit rotation of the tumbler.
  • Fig. 1 is a simplified partially cutaway illustration of a keying system, constructed and operative in accordance with an embodiment of the present invention, including a master key and master key element;
  • Fig. 2 is a simplified partially cutaway illustration of the master key used in the keying system of Fig. 1, and Fig. 2A is a detailed portion of Fig. 2;
  • Fig. 3 is a simplified partially cutaway illustration of an intermediate key used in the keying system of Fig. 1 , constructed and operative in accordance with an embodiment of the present invention, and Fig. 3 A is a detailed portion of Fig. 3;
  • Fig. 4 is simplified partially cutaway illustration of the intermediate key inserted in a keyway of a cylinder lock of the keying system of Fig. 1, constructed and operative in accordance with an embodiment of the present invention, wherein a biasing device urges the master key element into a recess formed in the intermediate key;
  • Fig. 5 is simplified partially cutaway illustration of the intermediate key being turned in the keyway, thereby moving the master key element away from its original position;
  • Fig. 6 is simplified partially cutaway illustration of removing the intermediate key from the keyway and thereby removing the master key element from the cylinder lock, in accordance with an embodiment of the present invention.
  • Keying system 10 may include a cylinder lock 12 that has a tumbler 14 with a key way 16 and tumbler pins 18 (seen in Fig. 6).
  • Driver pins 20 are disposed in the cylinder lock 12, as is known in the art.
  • a master key element 22 may be disposed in the cylinder lock 12.
  • the master key element 22 may be positioned between the tumbler 14 and one or more driver pins 20.
  • the master key element 22 is a rod-shaped element that lies over three out of a total of five driver pins 20. It is appreciated that the invention is not limited to this number of pins or configuration of master key element 22.
  • the master key element 22 forms together with tumbler pins 18 and driver pins 20 a master key combination that is alignable with a shear line 24 by insertion of a master key 26 into keyway 16. Accordingly, the master key 26 may be inserted into keyway 16 for turning the tumbler 14 about the shear line 24.
  • the master key element 22 effectively neutralizes the driver pins that it lies over. That is, the driver pins that the master key element 22 lies over do not participate in alignment with the shear line upon insertion of the master key 26 into keyway 16.
  • An intermediate key 28 may be provided, which may be formed with a recess 29 along its shank.
  • intermediate key 28 has key cuts such that when it is inserted in keyway 16, it aligns the tumbler pins 18, the driver pins 20 and the master key element 22 with the shear line 24 to permit rotation of the tumbler 14.
  • intermediate key 28 also displaces the master key element 22 so that the master key element 22 is no longer alignable with the shear line 24 by means of the master key 26. This may be accomplished by the action of one or more biasing devices 30 (e.g., coil springs) that urge the driver pins 20 against the master key element 22 (over which driver pins the element 22 lies).
  • the biasing devices 30 urge master key element 22 into recess 29, as seen in Fig. 4.
  • FIG. 5 After insertion of intermediate key 28 into keyway 16, rotation of intermediate key 28 may move master key element 22 away from its position between tumbler 14 and the driver pins 20. The master key element 22 is trapped in recess 29. Referring to Fig. 6, removal of intermediate key 28 from keyway 16 removes the master key element 22 from the cylinder lock 12.

Abstract

L'invention concerne un système de cléage qui comprend : une serrure à barillet comportant une gorge qui présente un chemin de clé et des broches à gorges, des broches d'entraînement étant disposées dans la serrure à barillet ; un élément clé maître disposé dans la serrure à barillet et formant avec les broches à gorges et les broches d'entraînement un ensemble clé maître pouvant être aligné sur une ligne de rupture par insertion d'une clé maître dans le chemin de clé, la gorge étant rotative le long de la ligne de rupture ; et une clé intermédiaire, qui lorsqu'elle est insérée dans le chemin de clé, aligne les broches à gorges, les broches d'entraînement et l'élément clé maître sur la ligne de rupture pour permettre la rotation de la gorge, et déplace l'élément clé maître de façon que ce dernier ne puisse plus être aligné sur la ligne de rupture au moyen de la clé maître.
