Definitions

  • the present invention relates to a cylinder lock. More specifically, the present invention relates to cylinder lock of pin tumbler type with pick-resistant mechanism to prevent it from being opened by conventional lock picking or bumping methods.
  • a typical cylinder lock in the prior state of the art generally includes a housing compressing a plurality of driver pin bores; a plug, rotatable within the shell, compressing a plurality of combination pin bores facing to their corresponding driver pin bores on the housing; a plurality of spring loaded driver pins seated in the driver pin bores on the housing, a plurality of combination pins resided in the combination pin bores on the plug.
  • the locking mechanism is created by having driver pins extended into the combination pin bores on the plug so to block the plug from rotating. The other end of the combination pins expose to an opening keyway for receiving and transferring external force from a pie-determined key profile.
  • an exemplary cylinder lock that comprises a housing having a through bore and a plurality of driver pin bores communicating with the through bore and outer peripheral surface; a plurality of driver pins and driver springs being sHdably disposed into the driver pin bores then sealed by driver pin bore seals; a plug rotatabe in the through bore in the housing having a keyway, a plurality of balancing pin bores defined in a longitude pattern on outer cylindrical surface that each balancing pin bore partially overlapping with the keyway, and a plurality of combination pin bores defined also in a longitude pattern on outer cylindrical surface and angularly spaced apart from the balancing pin bores that each combination pin bore communicating with one of the balancing pin bores.
  • the combination pin bores are arranged such that each one of the combination pin bore extends coaxially with a corresponding one of the driver pin bores when the plug is in a first rotational orientation relative to the housing.
  • a plurality of combination pins are slidably disposed into the combination pin bores, and a plurality of spring balancing pins and coiled compression balancing springs being slidably disposed into the balancing pin bores.
  • the balancing pin bores are sealed by balancing pin bore seals.
  • the main difference between the cylinder lock of the present invention with the cylinder lock in prior art is the initial-on-duty pin. Almost all the cylinder lock in the prior art use its driver pins as its i ⁇ itial-on-duty pins which span the plug from rotating within the lock housing while the combination pins or pin sub-assemblies are normally exposed to the opening keyway. This pin-configuration makes lock picking or bumping practically or theoretically easy.
  • the cylinder lock of the present invention uses the combination pins as the initial-on-duty pins and isolates these pins from the opening keyway. Each combination pin's position is not controlled directly by the key profile and the driver spring as it is in the prior art, but by the compound force of its corresponding balancing spring and driver spring.
  • the extension force of the balancing spring at its initial preloaded length within the balancing pin bore is greater than the extension force of its corresponding driver spring at its initial fully loaded length within the driver pin bore.
  • the key profile can only touch the balancing pins and move them to such new positions that the top end of all combination pins being just tangent to the outer cylindrical surface of the plug, or as we say the share line of the locking mechanism.
  • the cylinder lock of the present invention makes it impossible to unlock the lock by means of conventional lock picking or bumping technologies.
  • the above mentioned new locking mechanism may be achieved also by a minor modification which replaces the balancing pin, balancing spring and balancing bore seal with a magnetic balancing pin and a magnetic seal pin.
  • the extension force of the balancing spring is substituted by the repulsive force of the magnetic pin pair.
  • the repulsive force of the magnetic pin pair at their biggest separation is greater than the extension force of the driver spring at its fully loaded length.
  • the magnetic poles of the magnetic balancing pin and magnetic seal pin are arranged in such way that the like poles of the magnetic balancing pin and the magnetic seal pin are facing each other so they are repelled each other within the balancing pin bores on the plug all the time.
  • all components except the magnetic balancing pins and magnetic seal pins are made of non-magnetic material, such as brass.

Abstract

L'invention porte sur une serrure à barillet haute sécurité munie d' un boîtier comprenant une pluralité d'alésages de goupille d'entraînement pour disposer des goupilles d'entraînement à ressort; d' une fiche pouvant tourner dans le boîtier comprenant une pluralité d'alésages de goupille d'équilibrage pour disposer des goupilles d'équilibrage à ressort et une pluralité d'alésages de goupille de combinaison pour disposer des goupilles de combinaison. Chaque goupille de combinaison est prise en sandwich entre une goupille d'entraînement et une goupille d'équilibrage. La force d'allongement du ressort d'équilibrage au niveau de sa longueur de précharge est supérieure à la force d'allongement du ressort d'entraînement au niveau de sa longueur de charge totale. La force composée amène au moins une goupille de combinaison à s'étendre partiellement dans un alésage de goupille d'entraînement correspondant dans le boîtier quand la fiche est dans sa première orientation angulaire lorsqu' aucune clé n'est engagée. Le profil de clé pousse les goupilles d'équilibrage à se déplacer vers une position telle que toutes les surfaces de contact des goupilles de combinaison et des goupilles d'entraînement se trouvent sur la ligne de cisaillement de la serrure. L'ensemble goupille d'équilibrage, ressort d'équilibrage et joint de ressort d'équilibrage peut être remplacé par un ensemble goupille d'équilibrage magnétique et goupille de joint magnétique.
