Definitions

  • the present invention relates to a lightweight firearm equipped with a mechanical safety locking device disposed in the grip of the lightweight firearm.
  • a firearm is normally equipped with a manually actuated safety catch which has the function of preventing the firearm from discharging accidentally or involuntarily, preventing operation and/or activation of the firing mechanism thereof, directly or indirectly.
  • FIG. 1 shows an exploded view of a short lightweight firearm with a grip safety.
  • the internal firing mechanism of a pistol with a safety catch comprises at least a hammer ( 1 . 1 ), a hammer stirrup ( 1 . 2 ), a hammer spring ( 1 . 3 ), a trigger ( 1 . 4 ), a trigger bar or hammer bridge ( 1 . 5 ), a safety catch ( 1 . 6 ), a grip safety ( 1 . 7 ) and a firing pin ( 1 . 8 ).
  • the hammer ( 1 . 1 ) rotates around the hammer pin ( 1 . 9 ), moving from an idle position to a retarded position.
  • the hammer spring ( 1 . 3 ) through the hammer stirrup ( 1 . 2 ), exerts a force on the hammer ( 1 . 1 ).
  • the hammer ( 1 . 1 ) After this movement by the components of the firing sequence, the hammer ( 1 . 1 ) remains in a fixed position due to the fact that the safety catch ( 1 . 6 ) prevents rotation thereof with respect to the pin ( 1 . 9 ).
  • the trigger bar ( 1 . 5 ) moves in the direction of the barrel ( 1 . 10 ) towards the rear of the gun ( 1 . 11 ).
  • the appendix ( 1 . 12 ) of the grip safety ( 1 . 7 ) allows the trigger bar ( 1 . 5 ) to move so that it comes into contact with the safety catch ( 1 . 6 ), causing it to rotate around the safety catch pin so that the hammer moves freely and the tension accumulated in the hammer spring is released, causing it to rotate suddenly and strike the firing pin ( 1 . 8 ), causing ignition of the gunpowder in the cartridge and subsequent discharge.
  • the function of the sear spring ( 1 . 13 ) is to return the trigger bar ( 1 . 5 ), safety catch ( 1 . 6 ) and grip safety ( 1 . 7 ) to the idle position. If the gun is not being gripped the appendix ( 1 . 12 ) of the grip safety ( 1 . 7 ) prevents the trigger bar ( 1 . 5 ) from moving in the event that pressure is exerted on the trigger ( 1 . 4 ), avoiding completion of the firing sequence.
  • the present invention seeks to resolve one or more of the previously expounded drawbacks by means of a mechanical safety lock device such as that claimed in the claims.
  • An object of the invention is to provide a mechanical safety locking device electromechanically coupled to an authenticator device that provides stable interlocking in an active safety position, where the interlocking can only be deactivated by means of a personalised predefined password associated with a specific user.
  • Another object of the invention is to supply a mechanical safety locking device positioned in the grip behind the trigger of the lightweight firearm, maintaining the structural characteristics of the grip and preventing or allowing use of the firearm by a previously authorised person through the authentication device.
  • FIG. 1 shows an isometric perspective view of a lightweight firearm according to the state of the art
  • FIG. 2 shows a perspective view of a firearm that includes a mechanical safety locking device
  • FIG. 3 shows an elevational view of the lightweight firearm that includes the mechanical safety locking device
  • FIG. 4 shows a block diagram of the mechanical safety locking device.
  • FIGS. 2 and 3 show a mechanical safety locking device disposed between the outer face of the grip of the lightweight firearm frame and the inner face of a side of the handgrip; and which has an active position and an inactive position combined with a disinterlocked and interlocked position, respectively, electromechanically supplied by an authenticator device ( 7 . 1 ).
  • the mechanical blocking device comprises a trigger lever ( 2 . 1 ) that cooperates with a trigger bar ( 1 . 5 ) or firearm hammer bridge; an interlocking element ( 2 . 4 ) or interlock bolt for interlocking the trigger lever ( 2 . 1 ); a displacer element ( 2 . 6 ) for moving the interlock bolt ( 2 . 4 ) between the interlocked position, defined by the physical contact between an appendix ( 2 . 12 ) and the interlock bolt ( 2 . 4 ), and the interlocked position, defined by the absence of physical contact between the appendix ( 2 . 12 ) and the interlock bolt ( 2 . 4 ).
  • the trigger lever ( 2 . 1 ) has a broken zig-zag line shape, comprising a first section ( 2 . 2 ) which is in physical contact with one of the parallel sides of the trigger bar ( 1 . 5 ), which extends in a substantially straight line from the trigger ( 1 . 4 ) area towards the firing pin of the firearm, folding upon itself, i.e. folding 180° along the exterior of the first section ( 2 . 2 ); this second section ( 2 . 3 ) extends up to the central body of the trigger bar ( 1 . 5 ) next to the trigger ( 1 . 4 ) area; and a third section ( 2 . 12 ) or appendix perpendicular to the second section ( 2 . 3 ).
  • the interlock bolt ( 2 . 4 ) interrupts the axial movement of the appendix ( 2 . 12 ) and, therefore, of the trigger lever ( 2 . 1 ).
  • the trigger lever ( 2 . 1 ) cannot move or slide, thereby preventing completion of the firing sequence, even if an authorised user actuates the trigger ( 2 . 8 ).
  • the trigger lever ( 2 . 1 ) can move freely.
  • the grip safety ( 1 . 7 ) is in physical contact with the end of the first section ( 2 . 2 ) of the trigger lever ( 2 . 1 ).
  • the first section ( 2 . 2 ) is disposed in the interior of the firearm body and is in contact with an element of the firearm firing sequence.
  • the other sections ( 2 . 3 , 2 . 12 ) of the trigger lever ( 2 . 1 ) are disposed on the exterior of the firearm in such a manner that a side wall ( 2 . 5 ) of the grip area of the firearm frame is disposed between the first section ( 2 . 2 ) and the second section ( 2 . 3 ) of the trigger lever ( 2 . 1 ).
  • the trigger lever ( 2 . 1 ) has a broken zig-zag line shape which allows part of the components of the mechanical safety locking device to be disposed in the exterior of the firearm frame, such as the interlock bolt ( 2 . 4 ) and the displacer element ( 2 . 6 ), which are hidden from sight and fixed to the sides ( 3 . 1 ) of the grip, in such a manner that the mechanical locking device is invisible, providing greater safety to authorised users.
  • the locking device elements are distributed in the firearm frame.
  • the location of the various mechanical locking device elements in the firearm allows adaptation of the physical design and dimensions of each element of the device to prevent deformation thereof due to the pressure exerted on the trigger ( 2 . 8 ) on firing.
  • the trigger lever ( 2 . 1 ) moves axially towards the firing pin area of the firearm.
  • the interlock bolt ( 2 . 4 ) has been vertically moved away from the gun barrel and disposed in the disinterlocked position, in which the trigger lever ( 2 . 1 ) can move freely.
  • the trigger lever ( 2 . 1 ) returns to its idle position aided by a compressed recoil spring ( 5 . 6 ).
  • One end of the recoil spring ( 5 . 6 ) is fixed mechanically to the trigger lever ( 2 . 1 ) and the other end of the recoil spring ( 5 . 6 ) is fixed mechanically to the firearm frame or firearm grip.
  • the trigger lever ( 2 . 1 ) is not axially displaced towards the firearm firing pin area, as the interlock bolt ( 2 . 4 ) comes into physical contact with the appendix ( 2 . 2 ), thereby preventing completion of the firing sequence.
  • the displacer element ( 2 . 6 ) is adapted to move the interlock bolt ( 2 . 4 ) between the interlocked and disinterlocked position, said displacer element ( 2 . 6 ) being of the bushing ( 2 . 10 ) type, which is adapted to mechanically engage with the interlock bolt ( 2 . 4 ).
  • the bushing ( 2 . 6 ) is adapted to transform the rotational movement of a reducer motor ( 2 . 11 ), along a straight line, in this case, a substantially vertical movement whereby the position of the interlock bolt ( 2 . 4 ) is controlled.
  • the interlock bolt ( 2 . 4 ) may move in a direction perpendicular to the gun barrel or in another direction that prevents the free movement of the trigger lever ( 2 . 1 ) when it is in the interlocked position and releases the lever ( 2 . 1 ) when it is in the disinterlocked position.
  • the reducer motor ( 2 . 11 ) is disposed in a fixed predefined position that secures it to the grip ( 6 . 9 ) or firearm frame ( 2 . 5 ) by means of a mechanical fixing element ( 6 . 8 ), such as for example, a double bolt and screw assembly.
  • the reducer motor ( 2 . 11 ) is thus disposed in a fixed position with respect to the firearm body and there is a controlled displacement of the interlock bolt ( 2 . 4 ) with respect to that fixed point of the firearm body.
  • the grip ( 6 . 9 ) is fixed to the firearm frame ( 2 . 5 ) by means of a standard mechanical fixing subassembly, such as for example a set of screws ( 3 . 5 ).
  • Rails are disposed along the inner surface ( 6 . 7 ) of the grip that serve as a guide for the linear movement of the interlock bolt ( 6 . 4 ).
  • the inverted pattern of that made on the inner side of the grip ( 6 . 7 ) may be engraved on the surface of the interlock bolt ( 2 . 4 ) that comes into contact with the grip ( 6 . 7 ), further facilitating the linear movement of said interlock bolt ( 2 . 4 ).
  • the mechanical locking device also comprises an authenticator device ( 7 . 1 ) for generating electrical control signals that are sent to the reducer motor ( 2 . 11 ) to allow the interlock bolt ( 2 . 4 ) to move between the interlocked and disinterlocked position.
  • the authenticator device ( 7 . 1 ) is adapted to evaluate whether a user of the firearm is or is not authorised to use said firearm in accordance with a personalised password provided by a potential user of the firearm.
  • the authenticator device ( 7 . 1 ) sends an electrical signal to the reducer motor ( 7 . 11 ), which moves the interlock bolt ( 2 . 4 ) from an interlocked position to a disinterlocked position. Otherwise, if it is negatively verified, no electrical signal is sent from the authenticator device ( 7 . 1 ).
  • the locking device is in a permanently locked position and only allows use of the firearm upon identification of an authorised user.
  • the authenticator device ( 7 . 1 ) is assembled on the inner face of a side ( 6 . 7 ) of the firearm grip.
  • the authenticator device ( 7 . 1 ) comprises a power source ( 7 . 2 ), a status indicator button ( 7 . 9 ), a light signal ( 7 . 4 ), a central control unit ( 7 . 5 ) comprising a microprocessor ( 7 . 6 ) and a memory-type mass storage unit ( 7 . 7 ).
  • the authenticator device ( 7 . 1 ) includes a grip detection unit ( 7 . 8 ) and a grip transmitter-receiver, namely, a grip transceiver ( 7 . 3 ).
  • the power source ( 7 . 2 ) supplies electricity to all the components of the mechanical locking device and, in particular, to the displacer ( 2 . 6 ) wherethrough the position of the interlock bolt ( 2 . 4 ) is controlled.
  • the power source ( 7 . 2 ) is of the disposable battery type, rechargeable battery type, etc. If a rechargeable battery is used, a USB port shall be disposed to charge the rechargeable battery, for example.
  • the light signal ( 7 . 4 ) visually indicates whether the locking device is in the interlocked or disinterlocked position.
  • the personalised password can be introduced using a keyboard ( 8 . 1 ) disposed on firearm grip or using a portable alphanumeric keyboard ( 8 . 2 ) that allows remote connection through the transceiver ( 7 . 3 ) of the mechanical locking device.
  • the authenticator device compares it with a stored password. If the access code supplied and that stored coincide, the interlock bolt ( 2 . 4 ) is moved to the disinterlocked position, allowing the firearm to be used.
  • the grip detector ( 7 . 8 ) is adapted to allow the power source ( 7 . 2 ) to supply electricity to the different components of the authenticator device ( 7 . 1 ).
  • the personalised password may also be supplied by a transmitter device to the authenticator device ( 7 . 1 ) via the grip transceiver ( 7 . 3 ). Communication between the transmitter device and the grip transceiver is via a BLUETOOTH-type radio interface. Consequently, the user of the firearm does not have to introduce the personalised password, as when the two devices are within range of the radio interface, i.e. the two devices detect each other, the transmitter device emits a signal containing the personalised password to the grip transceiver ( 7 . 3 ), which retransmits said signal to the authenticator device ( 7 . 1 ).
