Definitions

  • Safety device for firearms The present invention relates to a safety device, particularly for firearms but also fully usable for hollow bodies other than the barrel of firearms or shot guns.
  • the application is particularly suited for weapons kept in military depots, arms dealers, guns in the home or during transport.
  • the weapon is not permanently damaged even if a forced extraction or drifting out of the safety device should be attempted, in comparison to a device comprising an explosive, and the risk for dangerous and damaging effects in the near-by environment is avoided.
  • a safety device for inserting in a firearm chamber or barrel and locking to a locked condition in a given position by means of locking elements, said safety device comprising a lock for locking the safety device in the given position by establishing a radial trust against the inner wall of the firearm chamber or barrel, and an activator for additional blocking of the locking elements in the locked position of same within said firearm, as a result of an attempt to remove the safety device with force from the locked position thereof, characterised in that said activator comprises a lock housing enclosing said lock and the locking elements, and a container containing an expansion fluid under pressure, said locking elements comprising a penetration pin for the penetration of said container so as to release the expansion fluid for filling all the voids in the safety device, when the force during the attempt to bring the device out of the locked position within the firearm exceeds a predetermined value.
  • the container comprises external threads for engagement in internal threads in one end of said lock housing, and is provided with a diaphragm for controlled penetration by said penetration pin of the locking elements, said penetration pin being provided on a cam shaft forming an extension of a lock cylinder of the lock, said penetration pin being kept a given distance from said diaphragm of the container in the locked position of said lock within the lock housing, said locking elements comprising trust elements radially extending from said cam shaft, and an expansion mechanism to urge said trust elements to a locking bearing under pressure against the inner wall of the firearm chamber or barrel, said expansion mechanism comprising cams on said cam shaft and arranged for the urging of said trust elements radially outward as a result of a rotating under force of said lock from the firearm chamber side, said trust elements comprising a trust arm and a trust pad at one end of said trust arm, said trust pad being shaped and structured so as to achieve a high friction against the firearm barrel or chamber even under a moderate rotating momentum to the lock from the chamber side, and said
  • a safety device wherein the at least one key or similar for locking/unlocking said lock is/are adapted for remote control and/or is/are programmable so as to be unlocked by an individual code only, said key or similar comprising a remotely releasable first locking part combined with a second locking part to be unlocked locally and/or wherein the remotely releasable first locking part comprises a radio, an audio or an optical receiver.
  • Fig. 1 schematically, partly in axial cross section and partly having a portion broken away illustrates a preferred embodiment of the safety device of the invention locked in position in a firearm barrel
  • Fig. 2 is a view according to the section I-I in Fig. 1, illustrating three locking pads to be cammed radially outward by tapered cams, and Fig. 3 further illustrates the safety device components within a firearm barrel or cartridge chamber.
  • FIG. 1 A preferred and typical embodiment of the safety device according to the invention is illustrated in Fig. 1 and comprises two main components: an outer activator 4 and a lock 2 centrally arranged within same.
  • the activator comprises an outer lock housing 10 surrounding the lock at the inner end, that is the end opposite the weapon muzzle, and a sealed container 12 at the other end of the activator, that is nearest the muzzle.
  • a safety mechanism is provided within the lock housing 10 and partly belonging to it and/or the lock 2.
  • the lock 2 comprises a lock cylinder 6 to be locked in position within the lock housing 10 by means of a key or similar, and a central extension protruding inwards within the lock housing, preferably in the form of a cam shaft 8.
  • the safety mechanism By interaction between the lock 2 and the activator 4, after the insertion of the safety device 1 in a firearm chamber and barrel 14, the safety mechanism is activated, thereby securing the firearm so that nobody except the owner or another authorized person can use it.
  • the safety device 1 is locked into position in the weapon with the aid of a locking means comprising a number of, such as three, trust elements 16 which are pressed radially against the barrel 14 inside.
  • the pressure is generated by turning the lock 2 and its cam shaft 8 and is due to a camming action between a cam below the inner end of each trust element 16 (see also Fig. 2 and 3).
  • Each trust element 16 comprises a radially directed trust arm 19 in the illustrated embodiment having a trust pad 20 at the outer end, said pad being adapted to be pressed with force against the inner wall of the barrel 14.
  • the shape and structure of the trust pads 20 can be varied in order to establish a high friction but without damaging the barrel wall.
  • the outer surface of the pads 20 could be transversely machined and being of a high density material so as to be pressed further into the barrel wall in a situation where the lock housing is pressed or driven with force in either direction in the barrel, in an attempt to overcome the securing of the weapon.
  • a window 22 in the lock housing 10 wall, for each trust pad 20 allows these to freely move between an outer trusting position in the locking position of the complete safety device 1, and an innermost position where each trust arm 19 is camming on a part of the corresponding cam 18 having a minimum radius.
  • the trust elements 16 can be supported in several ways, either to the lock housing 10 by the use of a supporting cage or similar (not shown), or to the lock cam shaft 8 in a similar way.
  • Fig. 2 is shown the situation where the trust elements 16 are riding on their corresponding low portion of each cam 18, and no radial trust is then applied between the trust pads 20 and the barrel.
  • the safety device 1 thus can be inserted into and removed from the gun barrel quite easily.
  • the safety device 1 is activated by turning the lock clockwise, thereby pressing the trust elements radially outward due to the interaction between the cams 18 and the trust arms 19.
  • Fig. 3 indicates how a sufficient momentum can be transferred to a corresponding trust force for each of the elements 16, in that openings 24 are provided in the outer surface of the lock cylinder 6, for a suitable locking tool (not shown).
  • a holding means (not shown) can be arranged for interaction between the lock cylinder 6 and the inner wall of the lock housing 10, such as protruding teeth circumferentially arranged on the cylinder 6 and adapted to interact with a ratchet groove or similar in the housing 10.
  • the function of the holding means is of course to avoid that the cam shaft 8 can be moved in the opposite direction without unlocking the lock 2.
  • Fig. 3 indicates the use of a more conventional single key, in that there is provided a keyhole centrally in the lock cylinder 6.
  • a programmable electronic key that can be released from a remote unit by encoded radio or audio signals or by optical means using modulated light.
  • the remote enabling signals can very well be transmitted from a command central, such as a military station.
  • the safety device lends itself to the combinations of keys, for example a centrally generated enabling command that unlocks a first locking part in all the weapons in a given area, combined with a code transferred by phone to each weapon owner or soldier for the unlocking of a second locking part.
  • Fig. 3 illustrates further how the container 12 is fixedly mounted in the muzzle end of the lock housing, in the preferred embodiment.
  • the container is filled with an expansion fluid 26 under pressure.
  • the container 12 end facing the lock 2 comprises a diaphragm 28, and a sharpened penetration pin 30 is arranged centrally at the free end of the cam shaft 8 a short distance from said diaphragm 28 when the lock 2 is in its hold position within the lock housing 10. In this position the safety device 1 is locked and securing the weapon, but the device is not activated in order to withstand a forcing attempt.
  • the safety device of the invention is quite simple to use.
  • the various elements can be of steel, other metal types or plastic materials, depending on the requirement. Reference numerals to the drawings
  • Container 28 Container wall diaphragm
