Definitions

  • the present invention refers to the technical field of weapons, and more specifically to safety arrangements for firing weapons.
  • the object of the present invention is to provide a reliable safety device for weapons, a drive mechanism and a control system for the same, said safety device being able to be controlled by the shooter, by a third user, by another transmitting device like a bracelet or by an emitter located in a region surrounding a target and a receiving device located in the weapon.
  • said kinematic shooting chain comprises basically the following pieces: the trigger (10), the trigger bar (20), the striker safety lever (30), the striker safety (40), the sear (50) and the striker (60) or firing pin. More specifically, the operation of the main parts involved in the weapon's shooting mechanism is as follows: when the trigger (10) is pulled, it moves the trigger bar (20) by means of a spring (6), as represented in figure 1A , wherein the trigger bar (20) in turn moves (through an upper protrusion) the striker safety lever (30). Said striker safety lever (30) has two functions, its upper front zone releases the striker safety (40) and its lower rear zone acts on the sear (50), which is the one that finally releases the striker (60), producing the shot.
  • the upper protrusion of the trigger bar (20) drops/lows whenever the weapon slide is not completely closed, said closed position being the natural position of the slide, in which it is aligned with the frame.
  • This downward movement of the trigger bar (20) is carried out to avoid that shots can be fired without the slide being completely closed.
  • This occurs in weapons because the slide has an area or footprint that houses the upper protrusion of the trigger bar (20).
  • the slide has an area or footprint that houses the upper protrusion of the trigger bar (20).
  • the present invention solves the above-mentioned drawbacks, providing a reliable and robust electromechanical safety device that maximises the security of the weapon while preventing accidental firing situations. Furthermore, a drive mechanism and a control system for the safety device is also provided, the latter being able to be controlled by the shooter or by a third user.
  • weapon any small arm or light weapon, such as a firearm, gun, shotgun, air gun, machine gun, pistol, rifle, revolver, etc. and non-lethal weapon or archery weapon as well.
  • the weapon is a weapon with a striker fired system, e.g., a pistol with a striker fired system.
  • safety position when the term "safe position” is mentioned in this application, it means that the weapon is disabled, and even if the shooter pulls the trigger there is no shot.
  • firing position when “firing position” is mentioned, it means that the weapon is enabled, that is, in the case that the rest of the original weapon locks are enabled, if the shooter pulls the trigger a shot is produced.
  • the safety device of the invention is applicable for weapons having a frame, a slide, a backstrap and a magazine or grip, wherein the transition from a firing position to a safe position is made by disconnection of the kinematic shooting chain, said kinematic shooting chain comprising a trigger, a trigger bar operated by the trigger and displaceable between a high position and a low position, a striker safety lever, a striker safety, a sear and a striker.
  • the safety device of the invention comprises a safety element for connect or disconnect the kinematic shooting chain; wherein said safety element is located inside the weapon at its rear part, communicating with the trigger bar and the backstrap of the weapon.
  • the safety element acts on the trigger bar, causing said trigger bar to move downwardly to its low position, so the trigger bar does not contact with the rest of the kinematic shooting chain, so regardless of whether the trigger is pulled, a shot is not produced.
  • the safety element acts on the trigger bar, causing said trigger bar to move upwardly to its high position, so the trigger bar does contact with the rest of the kinematic shooting chain, so a shot can be produced when the trigger is pulled.
  • the safety element is a rod comprising an upper protruding section located inside the weapon, preferably in contact with the trigger bar; a lower protruding section located in the backstrap of the weapon, projecting outwards from said backstrap, for operation by the user; and a central section located between both protruding sections.
  • said safety element is made from steel, especially indicated for its tenacity and hardness.
  • the steel can be a stainless or with some later treatment.
  • the safety element can also be made by a different metallic material or even in plastic.
  • the upper protruding section of the safety element is longer than the lower protruding section. This is not a trivial or random feature, but it pursues a well-identified objective. More specifically, the length of the upper protruding section must allow the trigger bar to move (forward and backward) when the trigger is at rest position (not pulled) or when the trigger is pulled, in both, the safe and firing positions.
  • This feature is critical in the firing position, since, if the upper protruding section is not long enough, when the trigger is pulled, the trigger bar would be released from the safety element, transmitting its movement to the rest of the kinematic shooting chain and possibly producing a shot, while the shooter thinks the gun is in a safe position, resulting in a serious safety problem.
  • the safety element can incorporate an elastic piece, or even that the safety element itself is flexible, to allow the trigger bar to descend, move downwards, independently from the safety element.
  • a drive mechanism of the safety device comprising a motor; a spindle attached to the motor; a pusher coupled to the spindle, configured for raising (firing position) or lowering (safe position) the safety element; and a housing in which the motor and the spindle are mounted, said housing being coupled to the weapon's backstrap.
  • the drive mechanism also comprises at least a magnet and a magnetic sensor, both attached to the pusher. Said elements, magnet and magnetic sensor allow to know the position of the pusher, which is relevant for many reasons explained below.
  • the drive mechanism further comprises an elastic element, located between the pusher and the housing, to counteract the force exerted by the original spring of the trigger bar of the weapon, which makes by default the trigger bar position in its highest position. This feature allows that the passage from firing to safe position is less abrupt.
  • Said control system comprises at least one flexible PCB (Printed Circuit Board) that allows adapting to the limited spaces available and the shapes of the weapon; a LED status indicator, connected to the flexible PCB; a battery; a main communication circuit attached to the battery; and an electrical connection, between the main communication circuit and the flexible PCB.
  • flexible PCB Print Circuit Board
  • the battery is located under the front area of the weapon's frame.
  • the battery can be housed on the backstrap of the weapon.
  • the proposed safety device (1) comprises a safety element (100) for connect or disconnect the kinematic shooting chain; wherein said safety element (100) is located inside the weapon in its rear part, communicating with the trigger bar (20) and the backstrap (4) of the weapon, as can be appreciated in figures 3A and 3B .
  • the safety element (100) acts on the trigger bar (20), causing said trigger bar (20) to move downwardly to its low position, as shown in figure 4C . Consequently, the trigger bar (20) does not contact with the rest of the kinematic shooting chain, so regardless of whether the trigger (10) is pulled, see figure 4D , a shot is not produced.
  • Figure 3C shows a detail view of the overlapping positions of the trigger bar (20) and the upper protruding section (101) of the safety element (100), both in the firing position and in the safe position of the weapon, see movement as indicated by the arrows.
  • the trigger bar (20) is in its rearmost and highest position possible, due to a weapon's spring (6) shown in figure 1A . This is its position when the safety element (100) is at rest (firing position) and the trigger (10) is not pulled. If the trigger (10) is pulled from this position, a shot is fired, as appreciated in figure 4B , omitting the rest of the weapon's safeties for simplicity.
  • the position of the weapon is firing position, the weapon is enabled, it depends on whether one pull the trigger (10) that a shot occurs.
  • the safety element (100) is in its highest position, which corresponds to the firing position of the weapon.
  • the weapon is in a safe position, i.e. disabled, so even if the shooter pulls the trigger (10), no shot is fired. This is because the safety element (100) is in its lowest position, which corresponds to the safe position of the weapon.
  • figure 4C the trigger (10) has not been pulled and is therefore in its most rearward position.
  • figure 4D shows the situation when the trigger (10) is being pulled and is therefore, temporarily, in its most forward position.
  • the weapon must continue to function as the original, so the trigger bar (20) must be allowed to drop whenever the slide (3) is open. Furthermore, it is foreseen that the safety element (100) does not require to be always in contact with the trigger bar (20), to allow the original operation of the weapon.
  • both the upper and lower protruding sections (101, 102) of the safety element (100) are oriented towards the rear part of the weapon, in the opposite direction to the direction of the shot.
  • the location of the sections (101, 102, 103) of the safety element (100) has been specifically designed to adapt to the particular morphology of the weapon, taking into account the small dimensions of a weapon (gun in particular) and the limited spaces in it.
  • the upper protruding section (101) of the safety element (100) forms an angle of less than 90° with the central section (103), preferably 75° as shown in figures 5 and 6 .
  • This feature is relevant, since it takes into account both that the main axis of the safety element (100) is parallel to the magazine or grip (5) axis and that the upper protruding section (101) axis takes into account the position of the trigger bar (20).
  • the lower protruding section (102) of the safety element (100) forms an angle of 90° with the central section (103). This is also relevant because it contributes to facilitate the assembly of the drive mechanism (200), as will be explained.
  • the upper protruding section (101) of the safety element (100) is longer than the lower protruding section (102), such that the trigger bar (20) is able to move (forward and backward), see figure 7 , when the trigger (10) is at rest position, not pulled, figures 4A, 4C , as well as when the trigger (10) is pulled, in both the safe and firing positions, figures 4B, 4D .
  • FIGS 8A - 8I show the drive mechanism (200) of the safety device (1) from the weapon's backstrap (4).
  • said drive mechanism (200) is based on a motor-spindle-pusher assembly, in particular comprising:
  • the firing position means that the weapon is ready to fire, with a shot being fired only if the shooter pulls the trigger (10).
  • the motor (201) is housed in the central axis of the backstrap (4), since this is the area where there is more space to house the motor (201), as shown in figures 8F, 8G and 8H .
  • a change of axis is required, which in this case is done through the pusher (203) in the backstrap (4) area, as shown in figure 8B .
  • said change of axis is done in other areas depending on the available spaces and morphology of each weapon.
  • the axis can be changed by the safety element itself.
  • the drive mechanism (200) also comprises at least a magnet (205) and a magnetic sensor (206) as a Hall sensor in figure 8H , both being coupled on a fixed PCB. Said magnet (205) and magnetic sensor (206) allow to know the position of the pusher (203), which is important for the following reasons:
  • a second magnetic sensor is placed, so that if someone, knowing that the state of the safety device is magnetically detected, wants to cause a malfunction of the status indication and brings a magnet closer to the safety device, that external magnetic field that can interfere with the status indication can be detected, and therefore it is possible to place the weapon in a safe position.
  • the drive mechanism (200) further comprises an elastic element (207), which is a compression spring in figures 8H, 8I .
  • Said elastic element (207) is located between the pusher (203) and the housing (204) of the drive mechanism (200) to counteract the force exerted by the original spring (6) of the trigger bar (20) of the weapon, which makes by default the trigger bar (20) position in its highest position.
  • Said original spring (6) is shown in figure 1A .
  • the trigger bar (20) is by default in its highest position (firing position), see figure 4A , the passage from safe position to firing position is smoother than the opposite movement (passage from firing to safe position).
  • This conventional situation makes the shooter feel insecure because when the order to move from firing to safe position is given, the motor (201) has to make a bigger effort than when moving from safe to firing position. Therefore, the elastic element (207) mentioned above is able to counteract the original spring (6) force of the trigger bar (20), said elastic element (207) making force in the opposite direction to the original spring (6), so that the passage from firing to safe position is less abrupt.
  • Figure 8C shows a cross-section of the rear area of a weapon including the safety device (1) of the invention, wherein the particular location and dimension of the safety element (100) can be appreciated.
  • a battery is housed in the backstrap (4) of the weapon, so that both the drive mechanism (200) and the battery are housed in said backstrap (4).
  • the backstrap (4) can also include control or identification electronics.
  • the battery and other electronic control components can be housed in other parts of the weapon. More in particular, according to the preferred embodiment of figure 9A , said control system (300) comprises:
  • the weapon can be controlled in different ways, to avoid accidental firing. More specifically, the weapon can be controlled:
