GUN WITH A DELAY FUNCTION

Abstract

Delayed action magazine-based self-loading firearm with gas piston action. Delay action prevents the movement of the self-loading firearm's slide and lock during the actual shot and will keep them closed. The construction of the delayed action stores the energy from the powder gas either mechanically or pneumatically, to be used later for the operation of the firearm's load-lock mechanism. The delayed action mechanism of a delayed action firearm consists of the body (E) and a guide (C) with its openings (D) placed inside it, through which the high-pressure powder gas escapes through the firearm's barrel (A) onward to the gas piston (F), which moves pierced by a pole (H), with the pole (H) being attached to the bottom piece (I). A spring (G) may be connected to the pole (H), with the pressure of the powder gas compressing either the spring (G) or alternatively the air by the gas piston (F) against the bottom piece (I). The retainer (K) stops the gas piston (F) into its back position leaving the spring (G) or air into compression. Through the action of the shooter or a separate automatic mechanism on the releaser (M) the bottom piece (I) is allowed to dash backwards with the help of the spring (G) or air. The bottom piece (I) is fixed to the firearm's slide (O), which uses the firearm's load and lock mechanism to perform the cartridge case removal and loading actions.

Claims

1. A delayed action firearm having a magazine and being of self-loading type, the delay function mechanism consisting of body (E) containing a guide (C) with openings (D), a connected rod (H) penetrating a gas piston (F) attached to the bottom piece (I) and a retainer (K) adjoined to the mechanism, a releaser (M) and springs (J, N) designed to operate them. The bottom piece (I) is connected to the firearm's slide (O), the powder gas energy being stored either into a spring (G) or air being squeezed between the gas piston (F) and the bottom piece (I), and from which the energy at a later selected moment is directed via the bottom piece (I) to the slide (O) for operating the load and lock mechanism to remove the spent cartridge and to move a new cartridge into the cartridge chamber, and to cock the firearm in preparation for the next shot.

2. A delayed-action firearm as described in patent claim 1, characterized in that pressurized air is squeezed with the help of powder gas indirectly into a separate container to be used later to achieve delayed action.

3. Any delayed action firearm similar to patent claim 1-2, characterized in that after firing of a shot the energy of the powder gas is stored to prevent the slide and lock from moving before the time set or adjusted by the shooter.

4. Any delayed action firearm similar to patent claim 1-3, characterized in that the delayed action is switched on separately the firearm otherwise functioning without a delay function.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The following is one possible execution option of a delayed action firearm delay mechanism.

[0026] FIG. 1

[0027] After the firearm has been fired the bullet passes the gas port (B) opening located in the barrel (A), through which very hot and high-pressure gas is allowed to be discharged through machined gas ports (D) on the guide (C) onward to the gas piston (F) inside the body (E).

[0028] FIG. 2

[0029] The gas will make the gas piston (F) pierced by a rod (H) lunge backwards pressing the spring (G) against the bottom piece (I). The gas piston (F) will lock into the backward position arrested by the retainer (K). The retainer (K) is operated by spring (J).

[0030] FIG. 3

[0031] The shooter will use the release lever (L), which moves the releaser (M), loaded by the spring (N). The claw of the releaser (M) will release the bottom piece (I), which is connected using a stiff joint to the slide (O) of the firearm. The force of the compressed spring (G) will make the bottom piece (I), rod (H) and guide (C), connected to it using a stiff joint, and the slide (O) of the firearm lunge backwards enabling the removal of the spent cartridge from the cartridge chamber and from the firearm and the reloading of a new cartridge from a clip or magazine into the cartridge chamber. The guide (C) will also take along with it the gas piston (F) while lunging backwards.

[0032] The return spring pushes the moving parts of the firearm back to the forward position and the delay mechanism will return into a position described in FIG. 1 to wait for the next shot by the same return spring. The skewed surfaces of the delay mechanism (P, Q, R, S) will make the retainer (K) and releaser (M) move aside out of the way of the guide (C), gas piston (F) and bottom piece (I), after which the retainer (K) and releaser (M) return to a state shown in FIG. 1 with the force from springs (J, N). It is possible to carry out the realization economically also without separate springs (J, N) with the retainer (K) and releaser (M) body acting as a spring-like elastic element attached to the body (E).
