Definitions

  • the present invention relates to locking apparatus generally and more particularly to a key combination element movably disposed in a key blank or key, and to locks actuated thereby.
  • cylinder locks generally include a plug (also called tumbler) arranged for rotation in a lock cylinder housing.
  • Plug pins are slidingly disposed in the plug and are arranged to move against driver pins, which are disposed in bores formed in the cylinder housing and are spring biased toward the axis of the plug rotation. Insertion of a properly cut key in a keyway provided in the plug moves the plug pins against the driver pins and aligns all the pins along a shear line defined by the plug outer circumference, thereby permitting rotation of the plug to cause operation of a latch or locking mechanism.
  • Cylinders locks are also known that are equipped with a movable element (e.g., pin) disposed in the key blade.
  • An auxiliary locking pin is spring-loaded in the cylinder housing.
  • the movable element aligns with the auxiliary locking pin and interacts therewith to align with the shear line and permit rotation of the plug. Even if a would-be thief were to pick the key-cut combination of the key, he still would not defeat the lock without additionally aligning the movable element with the auxiliary locking pin. The latter action is very difficult without an authorized key, and thus the lock provides high security.
  • Such locks are described, for example, in US Patents 5520035, 5784910 and 5839308 to Eizen et al., assigned to the assignee of the present application.
  • These patents describe a key blank that includes a generally elongate shaft portion defining a key combination surface adapted to have formed thereon key cuts which define a key combination.
  • the key blank includes a movable pin element retained within the elongate shaft portion. The movable pin element may be displaced in a single direction, outwardly from the key combination surface.
  • PCT Published Patent Application WO 00/57006 to Weinberger describes a key blank that has a body and a head.
  • the body includes key combination elements that facilitate the operation of a lock when inserted in a keyway of the lock.
  • At least one resiliently protruding pin element is provided on the body, mounted inside a cavity.
  • the resiliently protruding pin element partially protrudes from the cavity when no external force is exerted on it, and retracts inwardly into the cavity, when a predetermined force is exerted on it, whereby the resiliency protruding pin may actuate an internal mechanism provided within the lock.
  • US Patent 5437176 to Keller describes an additional tumbler that is disposed in a rotary lock cylinder, which is aligned by means of a control element disposed in the key, A blocking element is provided in a stator at a distance from this tumbler which, in a set rotational position of the rotor, radially displaces the control element with the core pin of the additional tumbler against a restoring force.
  • US Patent 6508091 to Donatini describes a cylinder lock with a key, the lock having a plug with at least one hole intersecting the keyway.
  • the hole is provided with two shoulders, one whereof lies further outward, the other one lying further inward with respect to the surface of the plug.
  • An auxiliary tumbler is accommodated in the hole and comprises an auxiliary pin, an auxiliary complementary pin and a spring acting by expansion between the auxiliary pin and complementary pin.
  • the tumbler can assume an elongated configuration, wherein the pin and the complementary pin are mutually spaced and axially offset angularly with respect to each other, or a shortened configuration, wherein they are aligned in mutual abutment without axially offset.
  • the key has an elastic element adapted to cooperate with the auxiliary tumbler to allow, with the key inserted, compression thereof to the shortened configuration and disengagement from the notch and rotation of the plug.
  • British Patent GB2161204 to Gallego describes pair of aligned moving bodies that are formed in opposite edges of a shank of a key.
  • Each moving body comprises an operating part and a rear part which is located in a blind hole.
  • a spring acts on the moving body so as to cause the head of the operating part to protrude beyond the shank, the moving body being retained in the hole by an annular rim.
  • the key is used with a lock which is provided with additional locking pins which are engaged by the moving bodies and driven thereby into an unlocking position.
  • a pair of moving bodies are provided in the straight edge of the shank of a key, the other edge of which is provided with teeth.
  • the present invention seeks to provide an improved key blank, key and lock, as is described more in detail hereinbelow.
  • a key blank (and/or key made therefrom, and lock provided therefor) including a generally elongate shaft portion defining first and second generally flat oppositely directed side surfaces, joined by edge surfaces, at least one of the first and second side surfaces cuttable to form key cuts that define a key combination surface, the shaft portion having a longitudinal axis that extends along a length thereof and a transverse axis that extends along a width thereof, and at least one key combination element movably disposed in the elongate shaft portion and adapted for touching a lock combination element disposed in a cylinder lock plug, characterized by the at least one key combination element including a resilient arm disposed in a recess formed in the elongate shaft portion, the resilient arm and recess being slanted at a non-zero angle with respect to both longitudinal and transverse axes of the shaft portion.
  • the key blank (and/or key made therefrom, and lock provided therefor) may include one or more of the following features.
  • the one or more key combination elements may have inherent energy for applying an urging force against the lock combination element.
  • the key combination element may resiliently protrude outwards from the recess beyond the first or second side surfaces or both of them.
  • the key combination element may have a chamfered portion that protrudes outwards from the recess.
  • Figs. 1 and 2 are respective front and side view illustrations of a key blank with a key combination element movably disposed therein, constructed and operative in accordance with an embodiment of the present invention
  • Fig. 3 is a transverse sectional illustration of a cylinder lock, constructed and operative in accordance with an embodiment of the present invention, showing the orientation of the key combination element when the lock elements of the cylinder lock are aligned along the shear line, in accordance with an embodiment of the present invention.
  • Key blank 10 may have a generally elongate shaft portion 12 extending along a longitudinal axis 13 and defining first and second generally flat oppositely directed side surfaces 14 and 16, joined by edge surfaces 18. Either one or both of first and second side surfaces 14 and 16 may have key cuts 20 formed thereon that define a key combination surface, thereby forming a key 22.
  • the key cuts 20 may be cut for interfacing any kind of lock pins, such as telescoping lock pins, as is well known in the art.

  • key combination elements 26 are movably disposed in key 22.
  • key combination it is meant that key combination element 26 is capable of touching a lock combination element disposed in a cylinder lock tumbler to bring about alignment with a shear line, as is described hereinbelow.
  • Key combination element 26 may include one or more resilient arms 28, for example, made of spring metal.
  • key combination element 26 includes a pair of resilient arms 28, one for each of side surfaces 14 and 16.
  • the resilient arm 28 may be disposed in a recess 30 formed in the elongate shaft portion 12.

  • Plug pins 48 and driver pins 50 may be, but do not have to be, telescopic. Insertion of key 22 in keyway 42 moves the plug pins 48 against the driver pins 50 and aligns all the pins along a shear line 52 defined by the plug outer circumference, thereby permitting rotation of the plug 46 to cause operation of a locking mechanism, e.g., a cam (not shown).
