  • a major reason for the need for two load-bearing surfaces is the surface area.
  • an amount of additional surface is usually required to absorb the shock generated by the recoil of the firearm during the discharge of the latter. Accordingly, since the surface area surrounding the hinge portion itself can not be increased, a second load bearing surface must be provided to absorb a portion of the recoil force shock.

No specific articulation and trunnion is required at the specific pivot axis, unlike most traditional smooth guns, if although the height dimension of the shotgun can be reduced.

  • surfaces of abutment surfaces 45 and 47 come into reciprocal contact along substantially all of the curved track 44 (see FIG. figure 7 ). This gives a substantial surface area that is sufficient, without more, to adequately absorb the recoil force when discharging the shotgun.
  • most other conventional double-barreled guns require two separate abutment surfaces to provide a sufficient abutment surface area to absorb the shock associated with the recoil force of the smooth-barreled shotgun during discharge. .

  • figures 7 and 8 the convex male hinge portion 46 and the concave female hinge portion 48 come into reciprocal contact along their respective lengths and widths, and over the substantial portion of their length along the abutment surfaces 45 and 47.
  • the total surface area of the curved track 44 is large relative to the surface area of a fixed hinge or conventional trunnion provided on a double-barreled rifle device.
  • the abutment zone or curved track 44 is capable of absorbing all of the recoil force generated upon 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, tolerances of two or more abutment surfaces must be precisely adjusted such that an 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. The present invention does not require any critical tolerance coordination of this type because of the unique substantial abutment surface provided by each curved track 44.
  • 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 stop zone 44, without departing from the scope of the present invention. No trunnion itself and no other hinge device is required at the pivot axis 50. In this way, a smooth-barreled shotgun with a lower profile can be obtained. If a trunnion or socket Specifically required to locate at pivot point 50, there would be a need for a substantial structure on the smooth barrel rifle surrounding the pivot point which would in turn require a larger overall height dimension of the shotgun. . As a result, the new curved track 44 of the present invention gives rise to a smoother, lighter and easier to handle rifle apparatus.
