摘要:
The mechanism comprises a main frame (1) and its extension (1′), which accommodate a barrel (21) with fixed mounting, a mobile bolt (22) and its guiding pin ensemble (66) and main spring (67) moving in the main frame (1), a mobile mass (34) and its assembly of guiding pin (60), push plate (61) and return spring (62), and a mobile mass catch sear (42) and its spring (7). The mobile mass pivots from a first position under the barrel to a downward position in reaction to the backward movement of the mobile bolt. The placement of the mobile mass in front of the chamber directs counteracting forces down on the barrel to prevent muzzle climb during operation.

The invention relates to improvements in the design and operating mechanisms in a KRISS-type firearm, or a firearm employing a mobile mass. In one aspect, the invention is an improved cocking lever assembly comprising a main pin provided with a tenon (9) at one end (E), with a supporting compression spring (5), a cocking button (3), and a retention means (4), attached to a mobile mass (1). This assembly allows direct activation of the mobile mass (1) by the action of the operator's force on the cocking lever. Advantageously, this cocking lever assembly can be mounted indiscriminately on the right or the left of the mobile mass (1) and therefore of the firearm, according to the user's preference. This cocking lever assembly combines certain safety criteria with the option of ambidextrous use often preferred in modern firearms.

The invention comprises an improved recoil control device comprising a bolt head and an inertia block for use in a variety of firearms. In one embodiment, the bolt head and inertia block are articulated so that the displacement of the bolt head results in a force component outside the firing axis of the barrel of the firearm. The device can be incorporated into firearms of a variety of sizes and configurations to produce recoil reduction and/or weight reduction advantages.

The invention relates to a stamped or braided form of a solid material or foil that can be inserted into a tank or container, for example to prevent an explosion of fuel inside the tank. Various combinations of materials can be used to produce the forms and braids. In a preferred embodiment, two or more stamped, helical forms of a metal foil material are interlocked or linked together, and a wire or fiber is placed at least partially in the center of one of the helical forms. This structure presents advantageous properties when used in fuel tanks, and resists deformation. In addition, certain forms or structures can be designed and used so they can be easily removed from the container or tank.
