Definitions

  • the present invention relates to a manual and tactical safety device to be assembled on an automatic or semiautomatic firearm and which can be presented in kit form adaptable to conventional commercially available firearms.
  • the safety device is a locking device which mandatorily requires manual release by the user independently of trigger pull.
  • the present invention also relates to a semiautomatic type firearm, such as a pistol, equipped with this device.
  • Safety mechanisms for firearms intended to prevent unintentional or inadvertent percussion are well-known. These safety mechanisms are of two types.
  • the safety device blocks the hammer in the cocked position ready to shoot, which nevertheless still involves risks if the weapon is dropped.
  • the system has the disadvantage of causing damage to the hammer and sear mechanisms or of causing the accidental firing of a bullet.
  • the firing pin is hooked by a mechanism which, when the trigger is pressed, releases the firing pin from its cocked position and thus allows percussion. In other cases, the firing pin is in an intermediate position between the percussion position and the armed position.
  • the stroke for fully cocking the firing pin is effected when the trigger is pressed thanks to the trigger bar. At the end of the stroke, the trigger bar is retracted and releases the firing pin. The latter, actuated by its spring, can then, by its forward movement, strike the primer of the cartridge located in the chamber.
  • This system generally does not have manual safety mechanism and therefore also involves a risk of inadvertent firing.
  • the present invention aims to provide a rapid manual safety mechanism to be assembled on a hammerless semiautomatic firearm, such as a pistol without firearm hammer, when such a safety is not provided on the original firearm.
  • the invention aims to provide such a safety mechanism provided with visualization and/or tactile marking or indexing of the firearm in the safety and ready to shoot positions respectively.
  • the present invention aims to provide a safety mechanism in kit form, which is relatively easily adaptable to a particular type of weapon while retaining the conventional structure of a firearm already in service, thus without requiring any additional machining of the weapon in question or of its component parts.
  • the kit can therefore be assembled without irreversible modification of the firearm.
  • Another goal of the present invention is to provide a mechanism which allows, with a single movement, to lock the firing of the weapon and likewise, with a reversed single movement, allows to release the locking without pulling the trigger, in order to prepare the firearm for firing.
  • An additional goal of the present invention is to provide such a safety mechanism which, in the safety position, does not block any element of the gun but prevents the trigger bar from releasing the firing pin without blocking the other parts. Therefore, this design would not involve any risk of damage, whatever the effort on the trigger.
  • Another aim of the present invention is to further allow the placing of a padlock preventing any shooting and thus to secure the weapon in its safe position when the gun is not used.
  • An additional aim of the present invention is to provide such a mechanism, which removes the requirement to press the trigger, when removing the slide, thus permitting to avoid unwanted fire when servicing the gun.
  • a first aspect of the present invention relates to a removable manual and tactical safety device for a hammerless or linear striker fired firearm having a frame, a slide with a slide cover plate, a trigger mechanism comprising a trigger, a trigger bar attached to the trigger and engaging by the intermediate of a connector the rear portion of a firing pin to prevent the firing pin from moving forward, the trigger bar being also capable by going down to release the firing pin for firing, when the trigger is pulled rearward, said safety device being intended to be attached at the rear of the slide and comprising a cylindrical body having a longitudinal recess, a first lever and a second lever being secured together according to the axis of said longitudinal recess, said cylindrical body having a transverse housing for lodging a push pin comprising a cogwheel having at least two cut cogs defining at least a first position and a second position of the push pin respectively, said first lever having a body provided on its external surface with at least two pinions teeth capable of cooperating with corresponding cut cogs, so that the rotating
  • the safety device further comprises one of the following characteristics or a suitable combination of such characteristics:
  • a second aspect of the present invention relates to a firearm of the Glock type comprising a removable safety device as recited above.
  • the connector of the trigger bar is pushed inwardly towards the slide axis by the protrusion of the push pin which is in an advanced position, the connector being prevented in this position to contact the trigger bar and further to unlock the latter for releasing the firing pin, when the trigger is pressed by the user.
  • the protrusion of the push pin is in a retracted rearward position, the connector being not prevented to contact the trigger bar and further to unlock the latter for releasing the firing pin, when the trigger is pressed by the user.
  • the manual safety mechanism hereinafter referred to as a "manual tactical safety system”
  • a conventional automatic or semiautomatic firearm such as a pistol of the Glock type during manufacturing or may be presented in kit form and adapted on a weapon of this type which is already in service.
  • the weapon modification will be very simply performed using the aforementioned kit corresponding to the respective firearm, the rest of the weapon remaining identical to the original firearm.
  • the safety mechanism of the invention which is particularly simple, may thus be adapted to any hammerless semiautomatic firearm in such a manner that no modification of the firing characteristics of said firearm is needed.
  • Figure 1 shows the conventional parts of a commercially-available Glock-type semi-automatic pistol. Only the parts of the firearm which are related to the operation of the device of the present invention are provided with reference numbers in Figure 1 .
  • FIG 2 represents an exploded perspective view of the various parts forming the safety device intended to be assembled on a Glock-type pistol as represented in Figure 1 .
  • the safety device 1 comprises a cylindrical body 2 having a longitudinal recess 3.
  • first lever 4 and a second lever 5 are assembled to the cylindrical body 2 and secured together by clicking them respectively within said longitudinal recess 3.
  • first lever 4 has a main body 6 extending with two teeth 7, and these teeth 7 are suitable to snap in a slot 24 provided in the main body 8 of the second lever 5.
  • a push pin 10 is located in a housing 9 provided transversally in the cylindrical body 2.
  • the push pin 10 is held in its housing 9 by a spring 11 cooperating with a pin 12.
  • Spring 11 and pin 12 permit to locate and maintain the push pin 10 by a pressure exerted by the spring 11, the pressure being perpendicular to the axis of the push pin 10.
  • spring 11 and pin 12 are located in a separate cavity 13 provided in the cylindrical body 2, parallel to the longitudinal recess 3.
  • the push pin 10 comprises two cut cogs 14A of a cogwheel while the external surface of the cylindrical body 6 of the first lever 4 comprises two pinions teeth 14B cooperating with the corresponding cut cogs 14A.
  • two conical recesses 30 are provided on the side of the push pin 10, each capable of lodging the tip of pin 12, thanks to the above mentioned pressure exerted by the spring 11.
  • the two conical recesses 30 respectively correspond to the "safe" and "ready to shoot” positions of the safety device (see below). Thanks to the cogwheel, the rotation of the levers 4, 5 permits the linear displacement of the push pin 10, perpendicularly to the axis of the cylindrical body 2.
  • the pinions teeth 14B on the first lever 4 cooperate with the cut teeth 14A on the push pin 10 to transform the rotation of the levers 4, 5 into a linear displacement of the push pin 10, the pin 12 passing then from one of the above-mentioned recesses 30 to the other one (see Figures 3c and 3d for the "ready to shoot” position and Figure 3e for the "safe” position).
  • the position, advanced or retracted, of the push pin 10 in the safety device 1 permits in use to prevent or authorize the trigger bar of the firearm to release the firing pin.
  • a classical gear can even be contemplated.
  • the safety device of the invention may be assembled easily on a firearm of the Glock type, as illustrated in Figure 4 .
  • the safety device comprises simple fastening means 21 located on the cylindrical body 2. Firstly, the user has to remove the slide cover plate 22 of the Glock firearm, located at the back of the slide 17. Then, the user secures the safety device 1 on the rear part of the slide 17, instead of the slide cover plate 22, thanks to the fastening means 21.
  • the fastening can be effected by sliding the fastening means 21 inside the back of slide 17.
  • Figures 5 and 6 illustrate the operation mode of the safety mechanism, and its interaction with the firearm.
  • the safety device is in a "safety position", and therefore even if the user presses the trigger, he will not be able to fire.
  • Figures 5b and 6b show the "ready to shoot position". In this position the weapon is able to fire.
  • the user has to rotate the first or the second lever as described above. As the two levers are interconnected, the displacement of the one causes the displacement of the other. Both positions of the levers 4, 5 are illustrated by Figures 8a and 8b respectively.
  • the safety device 1 is located on the firearm in the safe position.
  • the connector 23 of the firearm is pushed in the transverse direction (see arrow A) by the push pin 10 which is in an advanced position.
  • the connector 23 of the firearm is pushed and displaced towards the center, and closer to the longitudinal axis of the weapon. In this position, it is impossible for the connector 23 to reach and contact the trigger bar 15A and to lower the latter.
  • the trigger bar 15A always remains in contact with the firing pin 16 and cannot be separated from it. Consequently the firing pin 16 cannot be released. This makes the firing impossible, regardless of the trigger position.
  • the levers 4 and 5 of the safety device are in the high position and are visible during the preparation for firing. In this position the push pin 10 does not come out at the rear of the cylindrical body 2.
  • FIGs 6a to 6c and Figures 7a to 7c show different views of the firing parts with the push pin of the safety device in different positions: “a” is the “safety position, “b” is the “ready to shoot position” and “c” is the “firing position” respectively.
  • Figure 9 illustrates the assembling steps for the manual safety device 1 of the instant invention.
  • the internal pin 12 is assembled with its spring 11 (A).
  • said assembly is pushed within the recess 13 of the cylindrical body 2 (B) and the push pin 10 is inserted into the transversal housing 9 provided in the cylindrical body (C).
  • a tool such as a screwdriver the pin 12 is pushed against the force of the spring 11 in order to allow the tip of pin 12 to position itself in one of the conical recesses 30 (D).
  • the first lever 4 and the second lever 5 are assembled by clicking within the cylindrical body 2, the teeths 7 of the first lever 4 being clipped into the body 8 of the second lever 5 (E).
  • Trigger being in forward position, introduce the frame into the slide 17 up to locking by the slide lock 27;
  • a padlock 20 is provided to secure the firearm in its safe position when the firearm is not used.
  • the cylindrical body 2 of the safety device comprises a boring 18, provided parallel to the longitudinal recess 3 and the ends of which are aligned on the housing 9 of the push pin 10.
  • a groove 19 is provided in the push pin 10, and when the safety device is in the safety position, i. e. when the levers 4 and 5 are in the high position, and the push pin 10 is advanced, the boring 18 is aligned with the groove 19. In this way, the insertion of the padlock 20 is possible to secure the firearm, by the introduction of the ring of this padlock 20 in the boring 18.
