Definitions

  • the present invention relates to a device for the projection of a projectile by compressed air, the compression of which is obtained by an electromagnetic piston.
  • the invention also covers a method for controlling the compression spraying device by electromagnetic piston.
  • the power of the projectiles is limited in order to remain in the field of sporting, playful and strategic play.
  • electromechanical means comprise an electric motor and a set of pinions driven by said so-called “gear box” motor.
  • These pinions have two functions, one of supplying a thrust nose with a projectile and the other of propelling said projectile with pressurized air, from the thrust nose.
  • the thrust nose is a hollow tube, tightly connected to a fixed pressure chamber.
  • the assembly being designed to be housed in a replica weapon.
  • This thrust nose can assume two positions, a rear position allowing the introduction of a ball in front of said thrust nose and a forward position in which the thrust nose introduces the projectile into the barrel of the replica weapon.
  • This projectile usually a ball, is positioned in front of the thrust nose from a reserve.
  • the fixed pressure chamber comprises a piston, movable in translation in said fixed pressure chamber.
  • the front part of the movable piston carries sealing means with the fixed chamber in which it is movable in translation.
  • the rear of the piston rests on one end of a spring interposed between the rear of said piston, the other end of the spring resting on the bottom of a casing in which all the electromagnetic means are arranged.
  • the pinions and the motor ensure the displacement of the piston in the fixed chamber of pressure towards the rear of the chamber, generally by means of a rack, which compresses the spring and when the piston is moved back to the maximum of its translation, the spring is also compressed to the maximum, simultaneously.
  • the piston drive pinion is provided with a range without teeth, so that during its rotation, immediately after the maximum compression, said pinion releases the piston which is propelled forwards in the chamber under the effect spring relaxation. This displacement compresses the air in said chamber. This therefore greatly accelerates the air in the thrust nose and this air then propels the projectile, in this case the ball in the barrel.
  • This mechanism is very interesting because it uses electrical energy that can be stored in batteries or batteries to power the motor.
  • the electromechanical means are nevertheless high consumers of energy, in particular due to friction
  • This field is therefore looking for a mechanism which retains the advantages of electrical energy, which reduces consumption as much as possible so as to increase the capacity of the number of shots or for the same capacity to lighten the weight of the replica of weapon, which generates little or no vibration, shock and noise.
  • the field is above all looking for technical performance which consists, for the same power consumed, in delivering the optimal power and therefore in improving the projection efficiency of the projectile.
  • the present invention makes it possible to overcome the problems of the prior art, to provide new characteristics and even to propose control of the projection device.
  • a device for projecting a projectile according to claim 1 as well as steering methods according to claim 11 are provided.
  • This various constituents are in particular designed to be integrated into a casing which may be a replica of a weapon.
  • This replica weapon comprises at least one barrel intended to guide the projectile projected by the projection device according to the present invention.
  • a source of electrical energy must be associated with the projection device according to the invention to allow its operation, said source not forming part of the present invention and remaining within the reach of those skilled in the art. .
  • a sheath 10 which receives inside mobile electromagnetic means 12 and a thrust nose 14.
  • the sheath 10 has a cylindrical internal shape with a diameter D1.
  • the material of the sheath is made of soft iron with a very low carbon content or of an iron/cobalt alloy.
  • annular groove 10-3 is provided on the inner wall of the sheath.
  • the sheath 10 comprises at least one slot, in this case two slots 16-1, 16-2, each arranged along a generatrix, therefore parallel. These openings open out and allow communication between the interior of the sheath and the exterior of said sheath.
  • These slots 16-1, 16-2 have a length L and extend substantially from the rear end 10-2 of the sheath 10.
  • the sheath 10 receives the electromagnetic projection means 12 as detailed on the figure 3 , 4 and 5 .
  • These electromagnetic means 12 comprise at the rear end 10-2 of the sheath 10, a yoke 18 made of soft iron with a very low carbon content or iron/cobalt alloy.
  • This cylinder head is fixed on the rear end of the sleeve 10 by means of a counterbore with a diameter D2 ⁇ D1, receiving the thickness of the sleeve so that the cylinder head externally has a diameter D1 identical to that of the sleeve, as shown on the figure 1 .
  • This yoke 18 comprises a second counterbore with a diameter D3 ⁇ D2 so as to generate a so-called circulation space E.
  • this cylinder head 18 carries, in the preferred embodiment adopted, an axial passage hole 20, of diameter d , opening out on the front side of the cylinder head at 20-1 and on the rear side at 20-2.
  • the rear face 22 of the yoke constitutes the rear of the device.
  • the electromagnetic means 12 further comprise a permanent magnet 24, attached to the yoke 18 to which it is secured. This permanent magnet 24 takes the form of a cylindrical bar with a diameter equal to D3 .
  • the length of the permanent magnet 24 is such that the front end of the magnet 24 is located at a distance L1 from the rear face 22 of the yoke 18.
  • This permanent magnet 24 is axially magnetized, that is to say that the front end of the bar constitutes a north pole and the other rear end constitutes a south pole.
  • This permanent magnet 24 is pierced with an axial, central hole 26, also of a diameter d .
  • a field plate 28 is attached to the permanent magnet 24.
  • This field plate 28 is made of soft iron and this plate is in the form of a ring with an outside diameter D3 .
  • This field plate 28 is also pierced with an axial, central hole 30, also of diameter d .
  • This stack further comprises a damper 32 in the form of a ring of elastomeric material for example, attached to the field plate 28 and of the same outside diameter.
  • This ring also has a central hole.
  • the electromagnetic projection means 12 are completed by a piston 34.
  • This piston has a cylindrical section and an outside diameter equal to D2-e and an inside diameter equal to D3+e , e being considered as an air gap or an operating clearance.
  • the thickness of the piston 34 is therefore substantially equal to the circulation space E except for clearances e .
  • the piston comprises a front guide zone 34-1 and a rear guide zone 34-2 inside the sleeve 10.
  • a counterbore 36 is made in the thickness of the piston, counterbore which receives a winding 38 of a conductive wire, for example copper or aluminum, on at least one layer.
  • the ends 38-1 and 38-2 of the wire constituting this winding 38 are arranged to project at the rear of the piston and are connected, each for example by means of a terminal 40-1, 40-2, rigid and conductive , to the source of electrical energy, not shown.
  • the connection is for example obtained by a flexible braid 42-1 and 42-2 which connects the source of electrical energy and said rigid and conductive terminals.
  • the rigid terminals 40 provide in addition to the electrical connection, a mechanical guide and an anti-rotation effect because these terminals 40 are designed to pass through the slots 16-1, 16-2.
  • a piston head 44 Upstream of the front guide zone 34-1, on the front of the piston 34, there is provided a piston head 44, manufactured with said piston 34.
  • This head 44 has the shape of a teat with a rounded end, with a maximum diameter ⁇ .
  • the teat shape ensures an excellent air penetration coefficient.
  • means 46 for sealing relative to the inner surface of sleeve 10 are carried by said piston 34.
  • These means 46 for sealing may be in the form of at least one gasket of the segment type or, in the case shown , in the form of dynamic joints.
  • These dynamic seals consist in providing at least one peripheral groove 48, 3 grooves in line with the front guide zone 34-1 in the embodiment shown, in the zone where the space between the piston and the inner surface of the sleeve is the lowest e .
  • These grooves are spaced irregularly and possibly have different depths in order to generate depressions which annihilate any leaks. These grooves avoid the mechanical friction of a segment or a seal.
  • the thrust nose 14 comprises, as shown in detail on the figure 5 and 6 , a projection tube 50 with a front end 50-1 and a rear end 50-2.
  • the rear end carries a cap 52, manufactured with said tube, this cap having a profile conjugate with that of the piston 34 and more particularly of the head 44 of the piston 34 and of a diameter ⁇ greater than ⁇ to accommodate said piston .
  • This cap 52 comprises means 54 for sealing with the inner wall of the sheath 10, in the form of at least one peripheral groove, in this case two grooves 54-1 and 54-2, each intended to receive a seal 56 of the O-ring type, 56-1 and 56-2.
  • the cap 52 receives the head 44 of the piston and a reinforcement 58 is arranged in line with the contact surface as shown on the figure 7 , especially.
  • a seal 60 of the O-ring type, is arranged in a groove 62 made in the inner wall, in line with the rear end 50-2 of the projection tube 50. This zone being possibly reinforced in rigidity by the reinforcement 58, see figure 6 .
  • This seal 60 is smaller than that of the front tip of the head 44 of the piston in order to provide a seal with this front tip.
  • the thrust nose 14 also comprises means 64 for returning to position.
  • These means 64 for returning to position comprise a front abutment 66, formed and monolithic with the tube, a cup 68, capable of being mounted on the tube and coming to rest against said abutment, a cylindrical casing 70, made in two half -shells 70-1 and 70-2, intended to close around said projection tube 50, and a spring 72 interposed between the rear end of said casing 70 and cup 68.
  • the two half-shells of the cylindrical casing 70 are held in place by positioning lugs and by a peripheral circlip 74 which is housed in a groove 76.
  • the arrangement is shown once mounted on the figure 7 .
  • the sleeve received the thrust nose and more particularly the cap 52.
  • the casing 70 is held in the sleeve immobile in translation by the circlip 74 which cooperates with the groove 10-3 made in the sleeve.
  • the piston 34 is forward and its head 44 cooperates conjugately with the inside of the cap 52.
  • the front tip of the head 44 is introduced into the seal 60 carried by the inside of the rear part 50-2 of the projection tube 50.
  • the spring 72 pushes the tube forward.
  • the piston 34 has its rear part 34-2 which partially surrounds the bar 24, the concentrator 28 and the shock absorber 32.
  • the sealing means 46 have played their role and the piston has been perfectly guided in the sleeve 10 by the zones 34-1 and 34-2 during this recoil phase.
  • Ball B remains in front of the end of the projection tube.
  • Ball B receives pressurized air which launches it and accelerates it during its movement.
  • the air is compressed during the translational movement of the piston due to the sealing generated by the means 46 for sealing the piston 34 and by the gaskets 56-1, 56-2 for sealing the cap 52.
  • phase a/ corresponds to the air compression phase with the piston moving forwards with an acceleration phase kept constant followed by a braking phase b/ by reversing the polarity of the current , just before it comes to a stop. Then, the piston moves back slowly during a phase c/ consuming very little energy then the piston is slowed down in its backward movement during a phase d/, before returning to the initial position.
  • the movement of the piston is thus perfectly piloted and controlled to provide constant acceleration to the end of the stroke and to limit energy consumption.
  • vents are made at the edge of the holes 30 of the concentrator 28 and of the outlet of the cylinder head 18.
  • vents facilitate the evacuation of air from the device during the rearward translation of the piston and the introduction of air from outside the device during the forward translation of this same piston.
  • the flows are not turbulent as at the outlet of a rough hole and do not generate a drag, therefore energy losses and therefore an overconsumption of energy.
  • the head of the piston is in the shape of a teat for a good penetration in the air during the movement but the shape can present any improved penetrating profile, these shapes falling under aerodynamic studies within the reach of the man of the art of the domain.
  • the material of the piston can be chosen from composite materials in order to reduce the weight and to limit the disturbances of the magnetic fields, letting them act with maximum efficiency.
  • the ends of the conductive wires of winding 38 can also pass through passages made through yoke 18, the openings made on the sheath then being eliminated.
