Definitions

  • the present invention relates to gun locks generally and more particularly to chamber and magazine locks and to mechanisms for preventing unauthorized opening of such locks
  • the present invention seeks to provide an improved weapon lock.
  • a lock for use with firearms having a chamber and a magazine well communicating therewith for secu ⁇ n such firearms against unauthorized filing including a chamber pin element arranged to be placed in the chamber, and a locking assembly including an actuation member foi lockingly ret.-ining the chamber pin element in the chamber, the locking assembly being disposed at least partiallv within the magazine well, and wherein the chamber pin element is slidingly attached to the locking assembly and is lockingly slidable into the chamber
  • tne actuation member may be selectively engaged with the chamber pin element, the chamber pin element being free to slide with respect to the locking assembly when the actuation member is disengaged from the chamber pin element.
  • the chamber pin element includes at least one lug which upon actuation of the lock protrudes from the chamber pin element and fixedly abuts against an inner surface of the chamber, thereby lockingly retaining the chamber pin element in the chamber.
  • the inner surface is at least in propinquity to a depression formed in the chamber for receiving a base portion of a cartridge.
  • the chamber pin element includes a plunger including a proximal portion and a distal portion, the distal portion having a larger cross section than the proximal portion, and locking actuation of the lock moves the distal portion into contact with the at least one lug thereby to cause the at least one lug to protrude from the chamber pin element and fixedly abut against an inner surface of the chamber, thereby lockingly retaining the chamber pin element in the chamber, and unlocking actuation of the lock moves the proximal portion into contact with the at least one lug thereby to permit the at least one lug to be brought into a non-protruding relation with the chamber pin element.
  • the actuation member may be selectively actuated to move the plunger with respect to the at least lug.
  • the chamber pin element includes an anti-tampering mechanism which upon tampering with contact of the actuation member with the plunger while the at least one lug is in contact with the distal portion, substantially fixedly protrudes into a groove formed in the chamber pin element, thereby substantially fixing the plunger with respect to the at least one lug in a position wherein the at least one lug contacts the distal portion and fixedly abuts against an inner surface of the chamber, thereby lockingly retaining the chamber pin element in the chamber.
  • the distal portion is urged by a biasing device against the actuation member
  • the biasing device urges the anti-tampering mechanism towards the proximal portion upon tampering with contact of the actuation member with the plunger while the at least one lug is in contact with the distal portion, thereby causing the anti-tampering mechanism to substantially fixedly protrude into the groove formed in the chamber pin element
  • Figs 1A and IB are simplified partially cutaway and pictorial illustrations, respectively, of a lock for use with firearms, constructed and operative in accordance with a preferred embodiment of the present invention
  • Fig 2 is a simplified sectional illustration of the lock of Fig 1A, taken along lines II - II in Fig 1A,
  • Fig 3 is a simplified sectional illustration of the lock of Fig 1A, taken along lines III - III in Fig 2,
  • Fig 4 is a simplified sectional illustration of the lock of Fig 1A, taken along lines IV - IV in Fig 3,
  • Figs 5 and 6 are simplified sectional illustrations of the lock of Fig 1A with the lock lockingly assembled in the firearms, corresponding respectively to Figs 2 and 3, Fig 5 being taken along lines V - V in Fig 1A, and Fig 6 being taken along lines VI- VI in Fig 5, and Figs 7 and 8 are simplified sectional illustrations of an anti-tampering mechanism of the lock of Fig 1A corresponding respectively to Figs 2 and 3, Fig 8 being taken along lines VIII- VIII in Fig 7
  • Figs 1A and IB illustrate a firearm 5 and a lock 10 therefor constructed and operative in accordance with a preferred embodiment of the present invention
  • Firearm 5 here shown to be part of a rifle, may be any suitable firearm, having a chamber 12 and a magazine well 14 (Fig IB) communicating therewith Lock 10, which prevents unauthorized firing of firearm 5, preferably include ⁇ es a cnamoer pin element to arranged to be placed in chamber 12 and a locking assembly 18 for lockingly retaining chamber pin element 16 in chamber 12.
  • the locking assembly is disposed at least partially within magazine well 14.
  • locking assembly 18 is preferably substantially surrounded by magazine well 14 and is nearly completely enclosed thereby. This arrangement makes it nearly impossible to forcibly disengage locking assembly 18 from the chamber pin element 16 without simultaneously damaging firearm 5 to an extent which prevents it from being used in a normal manner.
  • Locking assembly 18 preferably comprises a hardened lock body 20 in which is disposed a pin tumbler lock 22. Suitable rotation of pin tumbler lock 22 with an appropriate key (not shown) rotates an actuation member 24.
  • Actuation member 24 preferably comprises a threaded eccentric member 26 which may be raised and lowered generally along an axis 28 upon rotation of pin tumbler lock 22. When chamber pin element 16 is slid in the direction of an arrow 15, actuation member 24 may be selectively engaged with a surface 30 formed in chamber pin element 16.
  • Actuation member 24 may be completely lowered and disengaged from chamber pin element 16, in which case chamber pin element 16 is free to slide with respect to locking assembly 18 along a track 32.
  • track 32 may be trapezoidally shaped, although it is appreciated that other shapes may be employed as well.
  • a stop 33 may be provided for limiting sliding travel of chamber pin element 16 with respect to locking assembly 18.
  • Chamber pin element 16 comprises at least one lug 34, most preferably a pair of lugs 34, which upon actuation of lock 10 protrudes from chamber pin element 16 and fixedly abuts against an inner surface of chamber 12, thereby lockingly retaining chamber pin element 16 in chamber 12, as will be described hereinbelow.
  • Chamber pin element 16 preferably includes a plunger 36 slidingly disposed in a bore 38 formed in a housing 40.
  • Plunger 36 preferably includes a proximal portion 42 and a distal portion 44.
  • Distal portion 44 has a larger cross section than proximal portion 42.
  • Figs. 2 and 3 illustrate lock 10 in an orientation wherein actuation member 24 contacts a proximally facing surface 31 of chamber pin element 16 and lugs 34 contact a portion of proximal portion 42. It is seen that lugs 34 do not protrude outwards of housing 40.
  • Figs. 5 and 6 illustrate lock 1U assembled in firearms 5. Chamber pin element 16 has been slid in the direction of arrow 15.
  • actuation member 24 may be selectively actuated to move plunger 36 with respect to lugs 34.
  • actuation member 24 has moved plunger in the direction of an arrow 46 thereby to move distal portion 44 into contact with lugs 34.
  • this causes lugs 34 to protrude from housing 40 of chamber pin element 16 and fixedly abut against an inner surface 48 of chamber 12, thereby lockingly retaining chamber pin element 16 in chamber 12.
  • Inner surface 48 may comprise, or is at least in propinquity to, an existing depression formed in chamber 12 for receiving a base portion of a cartridge (not shown).
  • unlocking actuation of lock 10 comprises rotating actuation member 24 to move proximal portion 42 of plunger 36 in the direction of arrow 15, opposite to arrow 46, so that proximal portion 42 is brought into contact with lugs 34 and lugs 34 do not protrude from housing 40.
  • Anti-tampering mechanism 50 preferably includes a pair of biased detents 52, which may be biased against each other with a spring 54. Detents 52 are positioned at an end 56 of distal portion 44. A spring 58 preferably presses against end 56 in the direction of arrow 46.
  • detents 52 are normally positioned distally (i.e., in the direction of arrow 15) of a pair of corresponding grooves 60 formed in housing 40.
  • spring 58 forces plunger 36 to move in the direction of arrow 46 so that detents substantially fixedly protrude into grooves 60, thereby substantially fixing plunger 36 with respect to lugs 34 and fixing lugs 34 in a position wherein lugs 34 contact distal portion 44 and fixedly abut against inner surface 48 (Fig. 6) of chamber 12, thereby lockingly retaining chamber pin element 16 in chamber 12.
