Definitions

  • the present invention relates to the supply devices or systems considered, in the general sense, to ensure the operation of compressed gas shooting devices in semi-automatic mode of various projectiles.
  • the present invention relates, indifferently, to devices for firing nails or the like, such as nail guns or staplers or, again, weapons, such as those firing projectiles based on malleable materials such as lead, for training in shooting or playing sports.
  • the present invention aims to remedy the above drawbacks by proposing a new supply device for the semi-automatic firing by compressed gas of projectiles of various shapes.
  • the object of the invention is to provide a new supply system making it possible to set up a projectile to be fired by a simple intervention on the ordinary control trigger and without there being a risk of 'a primer of double introduction of such projectiles into the launching chamber.
  • An additional object of the invention is to propose a supply device making it possible to obtain, during a single maneuver, the introduction or the setting in position of a projectile, then then its firing without risk of false maneuver .
  • Yet another object of the invention lies in the fact that it is possible to assume the various functions above with projectiles which can be considered to be of the same general caliber but which nevertheless exhibit variations in external configuration.
  • the magazine has a storage column associated with an elevator and opening in the head containing the sliding drawer offering a housing for receiving a projectile, the drawer being movable transversely against the action of an elastic member into a position. where the housing coincides with the bore opposite the barrel receiving chamber.
  • the magazine has a keying and coding window.
  • the piston slides, against the action of the elastic return means constituted by a spring, in the carriage guided in translation in the housing, and the transfer bar slides relatively on a shank formed by the piston being disposed between the latter and the cart.
  • the elastic return means biases the piston in the withdrawal position relative to the magazine and in the opposite direction to the action of the cocking rod to which the piston is connected, the spring having a force less than that of a spring. when closing the valve.
  • the transfer bar consists of a coping core with the tail of the piston and of a branch provided with an inclined ramp offset laterally relative to the axis of the barrel to cooperate with the transfer drawer of the magazine head.
  • the trigger is controlled in rotation against its return member by a branch of the cocking rod brought to the end of the controlled movement.
  • the trigger comprises a lug formed to cooperate with the front face of the carriage and with the rear face of the web of the bar associated with the insertion piston, so as to engage between the carriage and the bar in the sliding phase independent of the piston and the bar relative to the carriage.
  • the invention also relates to an apparatus for projecting or firing various projectiles of all types, applying the device of the invention.
  • Figure 1 shows the carcass 1 of a semi-automatic compressed gas firing device firing non-explosive projectiles, for example of the type of those made of malleable metal.
  • a semi-automatic compressed gas firing device firing non-explosive projectiles, for example of the type of those made of malleable metal.
  • Such an apparatus can be of the type of nail guns or, again, that of training or sporting weapons. In the latter case, they may be rifles or pistols within the meaning of the definition of weapons.
  • the carcass 1 supports a housing 2 containing the entire mechanism as well as a launching barrel 3 offering, inside the housing, a chamber 4.
  • the housing 2 comprises, for example at its upper part, a connector 5 for mounting a reserve of compressed gas 6 which may consist of a cartridge of any suitable type.
  • the connector 5 opens into a transfer capacity 7 which communicates via a conduit 8 with the chamber 4.
  • the conduit 8 is controlled by a shutter 9 of the valve or piston type permanently urged to close by an elastic member 10.
  • the shutter 9 is extended by a control needle 11 opening into a bore 12 formed in the housing 2.
  • the bore 12 is reserved for the passage of a striker 13, of the launched type, which is carried by a movable assembly 14 disposed in the 'axis of the barrel 3 at a distance from the rear part of the latter, that is to say that offering the chamber 4.
  • the crew 14 comprises a carriage 15 guided in axial sliding in a slide 16 presented by the housing 2.
  • the carriage 15 supports a cylindrical rod 17 whose rear end is provided with a stop 18.
  • a spring 19 is mounted concentrically on the rod 17 between the stop 18 and the front part 20 of the carriage 15, so as to always stress the rod 17 moving in the direction of the arrow f l .
  • the spring 19 has a force less than that of the spring 10.
  • the rod 17 represents the tail of an introduction piston 21 which is oriented towards the chamber 4 of the barrel 3.
  • the piston 21 is associated, at its base, to a transfer bar 22 comprising a core 23 which is free to slide axially on the shank 17 while being disposed between the base of the piston 21 and the front face of the carriage 15.
  • the transfer bar comprises a branch 24 extending in the direction of the barrel 3 parallel to the axis of the latter, being offset laterally.
  • the branch 24 forms an introduction ramp 25 whose function will appear in the following.
  • the supply device further comprises a trigger 26 mounted articulated by a pin 27 on the housing 2.
  • the trigger 26 is extended inside the housing by a lever 28 articulated by a pin 29 to a cocking rod 30 appearing in dashed lines in FIG. 1 and, more precisely illustrated in FIGS. 2 and 3.
  • the cocking rod 30 is, moreover, mounted on a pin 31 formed by the core 23 of the transfer bar 22. Beyond the pin 31, the cocking rod forms a branch 30a extending rearward in alignment with a stud 32 formed by a trigger 33 mounted free to pivot on an axis 34 carried by the housing 2.
  • the trigger 33 is arranged below the piston 21 and comprises a lug 35 intended to come to cooperate, as a retaining stop, with the front part of the carriage 15
  • the trigger 33 is associated with an elastic member 36 urging it permanently in pivoting in the direction for which the lug 35 is placed on the path of the carriage 15.
  • FIGS. 2 and 3 show that the cocking rod extends laterally to the branch 24 of the bar 22 which it partially overlaps, so as to constitute a guide and stop element opposing the rotation of the core 23 on the tail 17 of the piston 21.
  • the device further comprises a storage magazine 37 intended to be mounted and maintained, for example by a lever 38, in a housing 39 presented by the carcass 1 and / or the housing 2.
  • the magazine 37 as illustrated schematically by fig. 4, is shaped to internally delimit a storage column 40 intended to contain projectiles 41 which can be introduced into the column 40 by a packing window 42.
  • FIG. 1 shows that this window can be executed to assume a keying function in the case where the projectiles used are not symmetrical in relation to a median transverse plane.
  • Column 40 is associated with a spring elevator 43 which can be operated manually during the packing operation.
  • the elevator 43 is responsible for pushing the stack of projectiles 41 occupying the column 40 towards a drawer 44 for transfer and presentation occupying the upper part or head of the magazine 37.
  • the drawer 44 is capable of occupying, against the action an elastic member 45 of the pin type, two stable positions in which it has a housing 46, either in the axis and above the open section of the column 40, or in coincidence with a telescope 47 formed in the head of the magazine 37, along an axis perpendicular to that of the column 40 and offset laterally relative to the latter.
  • the housing 39 is provided so that the telescope 47 is permanently placed coincident with the open section of the chamber 4 and so that the drawer 44 occupies a plane corresponding substantially to that of the branch 24 of the transfer bar 22.
  • this housing 39 is arranged so that the head of the magazine is placed between the open section of the chamber 4 and the piston 21.
  • the feeding device described above operates as follows.
  • the spring 36 maintains the trigger 33 in its upwardly tilted position in which the lug 35 bears on the core 23 and represents a stop for the carriage 15.
  • the movable assembly 14 is held in the rear recoil position in which the introduction piston 21 is set back from the magazine 37.
  • the magazine 37 suitably packed with projectiles 41, is immobilized in a stable position by the lever 38.
  • the transfer drawer occupies the position according to FIG. 4 by offering the housing 46 in the axis of the column 40.
  • the first projectile 41 is introduced into the housing 46.
  • the branch 28 urges the cocking rod in the direction of the arrow f 3 .
  • the cocking rod moves the piston 21 and the tail 17 relative to the carriage 15 immobilized in the waiting position by the lug 35 of the trigger 33.
  • the sliding of the piston 21 and the rod 17 is performed in the opposite direction to that of the arrow f i , causing the elastic member 19 to be placed under compression.
  • the displacement of the piston 21 and of the transfer bar 22 has the effect of causing the ramp 25 to act on the slide 44 to move it in the direction of the arrow f 4 (fig. 4).
  • This has the effect of bringing the housing 46 lined up coincident with the telescope 47, at the moment when the piston 21 arrives in an introduction phase
  • the projectile 41, lining the housing 46 is in this way suitably presented facing the chamber 4 then introduced into the latter by the piston 21 urging it in axial thrust, as appears in FIG. 5.
  • the lug 35 engages between it and the front face of the carriage 15 by rotation of the trigger 33 under the action of the spring 36.
  • the piston 21 is biased in the direction of the arrow f 1 by the work restitution stored by a known return spring not shown.
  • the recoil of the piston cannot however intervene beyond the stop represented by the lug 35 bearing against the carriage 15.
  • the piston 21 remains engaged, at least in part, in the housing 46 of the drawer 44 maintained by the ramp 25 in the position of presentation of a projectile facing the chamber 4, as appears in FIG. 6.
  • the branch 30a of the cocking rod 30 makes contact with the lug 32 and then requests the trigger 33 in reverse pivoting against the action of the spring 36.
  • the striker 13 is thus moved in the same direction in the bore 12 and strikes the needle 11 of the shutter 9. This percussion occurs when the projectile 41 is completely introduced into the chamber 4.
  • the opening of the shutter 9 then delivers a charge of compressed gas supplied by the conduit 8, in the rear part of the chamber 4 closed by the head of the magazine 37 and by the piston 21. This charge of compressed fluid produces the launch of the projectile required to follow canon 3.
  • the charge of compressed fluid from the reserve 6 is delivered for a short time, since the spring 10 has a force greater than that of the spring 19. As soon as the kinetic energy resulting from the launching of the crew 14 has been absorbed , the spring 10 pushes the shutter 9 which interrupts the communication between the reserve 6 and the chamber 4.
  • the return spring urges the rod 17, the piston 21 and the core 23 in the direction of the arrow f, and brings the mobile assembly 14 back to the extreme position.
  • rear view as illustrated in fig. 1.
  • the core 23 is again applied against the front face of the carriage 15, so that the piston 21 is released from the housing 46, while the ramp 25 is erased relative to the drawer 44.
  • the spring 45 returns the drawer in the loading position of a new projectile pushed by the elevator 43 into the housing 46.
  • the return to the rear recoil position of the mobile assembly 14 authorizes the pivoting of the trigger 33 under the action of the spring 36, so as to bring the lug 35 in the abutment position relative to the front face of the carriage 15 and in contact with the soul 23.
  • the entire supply device is then ready to operate again, as described above as soon as the operator acts on the trigger 26.
  • the supply device represents a reliable, robust, inexpensive assembly capable of supplying, in the general sense, projectiles of various external shapes, but of the same caliber, without the risk of double introduction and of entrainment as a result of false maneuver.
  • the feeding device is particularly intended to be used for feeding weapons firing balls of malleable material and which are used for the practice of sport shooting or training, as well as for training in handling. combat arms.
