Definitions

  • the present invention relates to a sealing device, comprising a barrel holder, a barrel slidably mounted in the barrel holder, at the rear of which is provided a housing for receiving a propellant charge case provided with a bead, and arranged to receive a fixing buffer intended to be propelled under the action of the combustion gases of the load, an extractor, with an extraction claw intended to retain the case when the device is opened, mounted on the barrel holder to be pushed back towards the axis of the barrel holder by elastic return means, and a groove for passage of the extraction claw being formed in the axial plane of the barrel, with a ramp inclined towards the rear on the axis of the barrel.
  • Such an apparatus is already known, in particular from document FR-A-1 083 665.
  • This apparatus comprises an extractor having in particular two characteristics. In the firing position of the device, the claw of the extractor is in contact with the bead of the load; the extractor is pivotally mounted on a fixed axis.
  • the present invention aims to eliminate this hard point.
  • the present invention relates to an apparatus of the type mentioned above, characterized in that the extractor is mounted on the barrel holder free in translation, with axial clearance, between two rear and front stops formed by a notch lateral formed in the barrel holder, it is arranged so that, when the device is opened, it is moved forwards by the bead of the case of the load, the housing of which comprises a rear portion of slightly larger diameter large to receive the bead base of the case and thus allow the good closing of the device, the rear portion and the front portion of reduced diameter forming an abutment shoulder for the bead of the case, and, in the position of shooting, the extractor claw of the extractor is disposed in front of this abutment shoulder to provide an axial clearance between the shoulder and the claw.
  • the extractor comprises a front retaining rim, arranged to be moved between the stops of the notch, and around which it can pivot under the action of the ramp and recall means.
  • the extractor is arranged so that, in the firing position, its extraction claw is in contact with the ramp of the passage groove, formed in the barrel, and raised against the action of the return means to provide a radial clearance between a nozzle of the extractor and a bearing surface formed on the barrel holder and against which the spout is intended to come into abutment.
  • the apparatus shown in the figures comprises a barrel holder 1 and a barrel 2 slidably mounted in the barrel holder of axis 15.
  • the barrel holder is mounted in a stock 4, here formed by two half-shells 4 ′, 4 ⁇ .
  • the rear part 3 of the gun holder is arranged to constitute a cylinder head for the striker 6.
  • the gun receives a piston 7 intended to propel a fixing pad under the action of the combustion gases of a powder charge 8.
  • the case 10 of the charge 8 is housed in a receiving housing 9 formed at the rear of the barrel 2.
  • the housing 9 has a rear portion of slightly larger diameter to receive the bead of base 11 of the case and thus allow the good closing of the device, the rear portion and the front portion of reduced diameter forming a shoulder 30 for abutment of the bead.
  • a groove 12 has been formed for the passage of an extractor 13.
  • the groove 12 has a ramp 14 inclined towards the rear of the device on the axis 15 of the barrel.
  • the groove 12 opens into the area of the receiving housing 9 of reduced diameter receiving the charging case 10, in front of the enlarged rear area for receiving the bead of the case.
  • the extractor 13 ( Figure 3), generally planar and longitudinal, has a tapered extraction claw 16, intended to cooperate, through the groove 12, with the case 10 and the bead 11 of the load, a spout abutment 17, intended to cooperate with a bearing surface 18 of the barrel holder, parallel to the axis 15, and, extending perpendicular to the general plane of the extractor, a retaining flange 19.
  • the extractor 13 here consists of a cut sheet, the flange 19 having been obtained by bending at 90 °.
  • the extractor extends substantially parallel to the axis 15 of the device, with the stop spout 17 at the rear, the retaining flange 19 at the front, and, between the two, the extraction claw 16 projecting , but closer to the stopper spout.
  • the extractor 13 is mounted free in axial translation in an axial groove 20 of the barrel holder, its translational movement being however limited by two rear shoulders 21 and front 22 formed by a lateral notch 23 formed in the barrel holder and in which extends the retaining rim 19 which can therefore move between these two shoulders.
  • the extractor 13 is also mounted relatively free in radial, or lateral displacement, between the wall of the half-shell 4 ′ of the stick, by its external edge 24, on the one hand, and the flat 25 of the notch 23 , by the internal face of the rim 19, and the bearing surface 18 of the gun holder, by the internal face of the stopper spout 17, on the other hand. More specifically, the extractor 13 is mounted practically pivoting around its rim 19 in the notch 23, under the action of a compression spring 26 bearing against the outer edge 24 and the bottom of a recess 27 formed in the half-shell 4 ′ of the stick.
  • the extraction claw 16 In the open position of the device, the extraction claw 16 is behind the opening of the load receiving housing 9, the edge 24 of the extractor 13 is substantially parallel to the axis 15, the spout 17 being brought back into abutment against the bearing surface 18 of the barrel holder by the spring 26.
  • the extraction claw 16 In this closed, or firing, position of the device, the extraction claw 16 is in front of the shoulder 30, of abutment of the bead 11, of the housing 9 for receiving the load 8, in abutment against the ramp 14 of the groove 12, in the pivoted position.
  • barrel 2 After firing, and during the opening of the device, when the barrel is driven forward in the barrel holder, to eject the holster, barrel 2 moves forward and the extraction claw 16, under the action of the spring 26, slides along the inclined ramp 14 to first come into contact with the bead 11 and cancel the clearance ( Figure 5).
  • the distance from the tip of the extraction claw 16 to the axis 15 is substantially equal to one fifth of the diameter of the bead 11, in this case approximately 1.5 mm, the axial clearances possibly being equal, J, to approximately 1 to 2.5 mm and, t, to approximately 1 to 2 mm.
