Definitions

  • the subject of the present invention is a sound moderating device for clay pigeon shooting or leisure rifle.
  • the device according to the present invention aims to remedy this state of affairs and is particularly intended to considerably reduce the nuisance caused by recreational shooting in urban areas and clay pigeon shooting stands, so as to allow them to continue to exist near cities.
  • It consists of a tubular body adapting to the barrel (s) of the weapon and comprising an annular decompression chamber disposed at the rear of said tubular body, as well as a series of internal transverse deflectors maintained by spacers and provided with orifices allowing the passage of sheaves of lead and the evacuation of the wads.
  • FIG. 1 represents a longitudinal section of a rifle with two superimposed barrels equipped with a sound moderator
  • the Figure 2 is a cross section along the arrows AA of Figure 1
  • Figures 3 to 6 are cross sections along the arrows BB of Figure 1 showing different possible forms of the device
  • Figures 7 and 8 show in longitudinal section a rifle single-channel equipped with a sound moderator with concentric and eccentric mounting respectively
  • Figure 9 shows the device seen from the rear, according to arrow C in Figure 7
  • Figures 10 and 11 show the device seen from the front , respectively according to the arrows D in FIG. 7 and E in FIG. 8.
  • the device comprises a tubular body 1 provided at one end with a centering piece 2 in which the barrel (s) 3 are inserted, then at the other end a plug 4.
  • baffles or deflectors 5 held in place by means of spacers 6, as well as possibly an intermediate centering piece 7.
  • deflectors 5 as well as the plug 4 are machined with an orifice 8 to allow the free passage of the sheaves of lead as well as the evacuation of the flocks, as indicated by arrows F, while braking the speed of combustion gases which are one of the main sources of noise.
  • the intermediate centering piece 7 is pierced with several passages 9 to allow the return of the combustion gases in an annular decompression chamber 10 located between the two centering pieces, around the barrel (s) 3, the gas outlet being effected thanks to the discharge orifices 11 provided in the body 1.
  • the latter is an integral part of the weapon and covers the barrel (s) 3 over three quarters of their length from which a portion of the sighting strip 12 will have been removed beforehand.
  • the upper part of the body 1 is determined to coincide exactly with the remaining sight strip 12 so as to retain the original aim of the weapon (FIG. 1).
  • the decompression chamber 10 is located at the outlet of the barrel and is formed by the space located between a perforated sleeve 13 extending said barrel and the body 1 of the sound reducing device ( Figures 7 and 8).
  • the decompression chamber will be filled with a sound insulating product.
  • the centering piece 2 is unique and will advantageously include a split fixing ring 14 tightened by screwing onto the barrel 3 (FIG. 9).
  • the deflectors 5, as well as the plug 4 will be pierced with several holes 15 around the orifice 8 to allow the decompression of the sound moderator and thus allow to fire several successive shots without loss of performance.
  • the sound moderator of a single-barreled shotgun can be made eccentrically, the axis 16 of the body 1 not coinciding with the axis 17 of the barrel 3.
  • the orifices 8 of the deflectors 5 and of the plug 4 may have an increasing diameter from the outlet of the barrel (s) 3 towards the outside of the sound moderator, to allow the free passage of the sheaf of pellets as well as the evacuation of the flock , as indicated by arrows F, while braking the speed of the combustion gases which are one of the main sources of noise.
  • the sound moderator combined with subsonic clay pellet cartridges can reduce noise by around 70%.
  • the weight, shape and dimensions of the device described above may vary depending on the weapon as well as its caliber.
