Definitions

  • the present invention relates to firearms, and more particularly to double barrel guns superimposed.
  • Firearms in the variety of rifles have existed in many different forms and types for several decades. Different types of rifles have been developed for different types of shots. For example, and without limitation, there are smooth single-hinge guns, side-by-side smooth double-barreled rifles, superimposed smooth two-barreled rifles, single-shot smooth-action guns, gun guns semiautomatic rails, as well as various other types of smooth guns.
  • the technology of smooth guns continues to evolve to meet the different needs of shooting enthusiasts. A large number of factors are taken into account in the design of smooth guns, such as appearance, weight, feel, ease of use, end use and individual preferences of the fencers.
  • Especially shotgun double-barreled rifles are extremely popular among shooters.
  • Super-smooth two-barrel guns are particularly suitable for pigeon shooting.
  • the present invention relates to improvements made to two superposed smooth guns.
  • the overall weight of a super-smooth two-barreled shotgun represents a major problem for all models and all types of smooth barrel rifles of this type.
  • the lighter the shotgun the easier it will be to handle it.
  • the weight is particularly important.
  • the main object of the present invention is to provide a two-barreled rifle apparatus that utilizes a hinge assembly that absorbs the rearwardly-oriented compressive elastic force of a spring of a detent assembly, which reverses such a force and reorients the force towards the anterior portion of the firearm for the purpose of actuating the striker.
  • Another object of the invention is to provide a two-barreled rifle apparatus which involves a firing pin which is loaded by moving a helical spring toward the front portion of the rifle.
  • Another object of the invention is to provide additional security so that, when the trigger is not pressed and the linear hammer attempts to move toward the rear end of the firearm, the Linear hammer is blocked by the trigger and will not give rise to a discharge.
  • each linear hammer will systematically come into contact with a front portion of the trigger as the fingering (tail) trigger will remain in the lower position (front position). In this case, there is no action possible linear hammers on the rockers and therefore no percussion.
  • the stroke of moving parts is short.
  • the combination of high speed (proportional acceleration) and reduced stroke provides the fastest percussion times, on the order of 0.0018 seconds.
  • One aspect of the present invention involves a unique reverse direction detent assembly.
  • Each main coil spring of the linear hammer is cocked by compressing the spring toward the end of the firearm corresponding to the mouth.
  • the spring of one of the linear hammers relaxes and exerts a force directed rearward on the joint assembly which, in turn, redirects the force towards a striker in the direction towards the anterior portion or the end of the smooth-barreled rifle corresponding to the mouth. Thanks to this unique detent assembly, a unique safety mechanism can be obtained (which will be described below).
  • a shotgun apparatus 30 generally comprises a section 32 corresponding to the barrel disposed at the front or distal end of the firearm and a section 34 corresponding to the rocker / butt, disposed at the rear end or proximal of the shotgun apparatus.
  • the section 32 corresponding to the barrel includes a unit block 60 to which are fixed an upper barrel 62 and a lower barrel 64.
  • a pair of ejection assemblies 56, 58 is also housed in the section 32 corresponding to the barrel.
  • the rocker section 34 encloses the trigger assembly 38, the locking system 100, the internal cocking links, the security system 200, and various other operating parts of the smooth-bore rifle apparatus 30.
  • the butt of the shotgun is attached to the rear portion of the carcass.
  • the smooth-barreled rifle apparatus comprises in one embodiment, a two-barreled, superimposed shotgun.
  • the section 32 corresponding to the barrel comprises a first barrel or upper barrel 62 (see FIG. figure 3 ) arranged in alignment with a second barrel or lower barrel 64, while being mounted directly on the latter.
  • the over-and-under shotgun rifle 30 further comprises an end 36 occupied by the buttstock, which may include a recoil pad, and an end 37 occupied by the mouth.
  • the firearm 30 further includes a detent assembly 38 for discharging the firearm and a lever actuated locking system 40 for opening the breech of the shotgun apparatus.
  • the portion 32 corresponding to the barrel ends at the end of the shotgun, occupied by the mouth.
  • a hinge assembly 42 which is defined in part by a male hinge portion 46 (see FIG. figure 7 ) formed on the section 34 corresponding to the rocker and by a female hinge portion 48 (see figure 8 ) formed on the monoblock unit 60 of the section 32 corresponding to the barrel of the particularly smooth rifle apparatus.
  • a male hinge portion 46 On the male joint portion 46 is defined a curved abutment zone 44 (i.e., a curved track 44).
  • the abutment zone 44 further includes a convex abutment surface 45 which provides a main bearing surface for sliding contact with a corresponding concave abutment surface 47 (see FIG. figure 8 ) formed within the female hinge portion 48 on the one-piece unit 60.
  • the male joint portion may comprise a pair of abutment zones 44 and abutment surfaces 45, 47 formed on either side of the firearm 30.
  • the abutment zones 44 and the surfaces stop 45, 47 serve as joint and support surface for the articulation of section 32 corresponding to the barrel relative to the section 34 occupied by the rocker / butt and to absorb the recoil force of the firearm during the discharge.
  • the hinge assembly 42 defines a pivot axis 50 (see FIG. figure 3 ) which is remote or spaced from the abutment zones 44. A joint proper does not exist at the pivot axis 50.
  • the first curved abutment surface 45 and the second curved abutment surface 47 see FIG.
  • the abutment zone or the curved track 44 is capable of absorbing the totality of the recoil force generated during the discharge of the firearm. There is no need for a second stop zone or additional stop zone, as is the case with conventional two-barreled guns. Further, since two separate abutment surfaces are unnecessary, it is not necessary to coordinate the tolerances with respect to different and spatially separated contacting surfaces. Traditionally, the tolerances of two or more abutment surfaces must be precisely adjusted so that one abutment surface does not support a greater load than that supported by the other abutment surface. In addition, after repeatedly discharging, the moving parts and the lever mechanism of the shotgun will relax.
  • Another important advantage related to the curved track or to the abutment zone 44 lies in the fact that the curved track 44 itself provides the articulation or bearing surfaces against which the two portions of the shotgun come into contact. arrange for articulation purposes.
  • the pivot axis 50 (see FIG. figure 3 ) defined by the curved track or by the abutment zone 44 is spaced from the actual articulation surfaces (that is to say the abutment surfaces 45, 47). Accordingly, the actual positioning of the pivot axis 50 should not be located at a location on the smooth-bore rifle apparatus corresponding to a substantial amount of structure.
  • the defined pivot axis 50 may correspond to a location where no structure exists (i.e., below the lowest structure of the firearm) depending on the actual radius of the firearm. the abutment area 44. No trunnion itself and no other articulation device is required at the pivot axis 50. In this way, a smooth-bore rifle having a profile can be obtained. lower. If a specific trunnion or bushing were required to locate at the pivot point 50, a substantial structure would be needed on the smooth-barrel rifle surrounding the pivot point which would in turn require an overall height plus dimension. important of the shotgun. As a result, the curved track 44 gives rise to a rifle apparatus that is smoother, lighter and easier to handle.
  • ejection assemblies 56, 58 are shown operatively mounted on the one-piece unit 60 of the section 32 corresponding to the barrel.
  • the monobloc unit 60 provides the first part of the guns 62, 64 and serves as an interface with the section 34 corresponding to the rocker / butt.
  • the unitary unit 60 furthermore has the object of rigidly connecting the upper barrel 62 and the lower barrel 64 of the two barrel rifle apparatus.
  • Ejection heads 66, 68 are intended to undergo an outward thrust with a force sufficient to discharge from the monobloc unit in its entirety a consumed lead cartridge. If, for whatever reason, a discharge of the pellet cartridge were not obtained, the ejection heads 66, 68 would push the pellet cartridges away from the base end 70 of the cartridge. the monoblock unit sufficiently (approximately 10 mm) to allow the shooter to easily remove the cartridge or cartridges from the chamber.
  • the ejection system 56 includes an ejection spring 76 which imparts outward pretensioning to the other ejection elements.
  • a guide 72 of the ejection spring holds the spring in place.
  • the combination of spring 76 and spring guide 72 is inserted into appropriately sized openings in the barrels and is held in place by appropriate stops formed within the barrel assembly.
  • a linear ejection hammer 77 is coupled to the ejection system.
