摘要： An over-and-under shotgun apparatus includes a radius track which serves as a hinge for articulating the barrel portion of the shotgun apparatus relative to the receiver/stock portion of the shotgun apparatus. The radius track is defined by a female or concave portion formed on the monoblock attached to the shotgun barrels, and a male or convex portion formed on the frame or receiver section. The radius track defines a pivot axis that is spaced from the radius track. The radius track provides a substantial surface area sufficient to absorb all of the recoil force generated when the shotgun is discharged. No additional abutment surfaces are needed. A further aspect of the invention involves a novel trigger assembly, including a striker which moves toward the front end of the firearm when the firearm is cocked, and moves toward the butt end of the firearm when the trigger is pulled to discharge the firearm. Yet another novel aspect of the invention relates to a four-position safety switch for selecting the firing sequence of the upper and lower barrels.

摘要翻译： 一种下射式霰弹枪装置包括半径轨道，该半径轨道用作铰接件，用于相对于猎枪装置的接收器/存放部分铰接霰弹枪装置的枪管部分。 半径轨道由形成在霰弹枪筒上的整体上形成的阴或凹部限定，以及形成在框架或接收器部分上的凸形或凸形部分。 半径轨道定义与半径轨道间隔开的枢转轴线。 半径轨道提供足够的足够的表面积，以吸收在霰弹枪排出时产生的所有后坐力。 不需要附加的邻接表面。 本发明的另一方面涉及一种新颖的触发器组件，其包括当枪械被起动时朝向枪支的前端移动的撞针，并且当触发器被拉动以释放枪支时朝向枪支的对端移动。 本发明的另一新颖方面涉及一种用于选择上下筒的击发次序的四位安全开关。

摘要： Firing mechanism for fire arms, includes a hammer (5) revolving between a "cocked" position and a "tumbled" position which makes contact with the striker (4), a tumbler (8) which can retain the hammer (5) in the cocked position, a trigger (13) which controls the tumbler (8), an assembly (20) to make the hammer (5) revolve from its cocked position towards the striker (4) of the arm when the hammer (5) is released by the tumbler (8), and a security device containing a bolt element (27) which can be manually locked and which can lock the trigger (13). The bolt element (27), in the security position, not only cooperates with the trigger (13), but simultaneously with the assembly (20) to make the hammer revolve in order to prevent the hammer (5) from knocking against the striker (4) as long as the bolt element (27) is in its security position.

摘要： An improved semi-automatic shotgun of the type contains a magazine tube (8) around which is provided a cylinder (9) whose interior part communicates with an interior part of a barrel (2) of the invention. In this cylinder (9) and around the magazine tube (8), a piston (10) can be shifted by propulsion gases. The piston cooperates with a sleeve (12) provided with a rod (13) which can act upon the whole of the moving parts (14) on the one hand, and a control or pressure control valve (11) on the other hand is situated in the piston block (10).

摘要： A bolt for a firearm is described that can be used to chamber, extract, and/or eject different cartridges that have different outside rim diameters. In one embodiment, the bolt includes a bolt head that is configured to engage the rearward end of a plurality of different cartridges. The bolt may include an extractor that is configured to engage the rims of the plurality of cartridges and/or an ejector that is configured to bias the cartridge case out of an ejection port of the firearm.
