BRIEF SUMMARY
The present invention concerna an automatic hand firearm with mass obturation.
BACKGROUND OF THE INVENTION
The problem encumbering automatic hand firearms with mass obturation is the lack of safety in the forward position of the slide. As a consequence, when the firearm is forcefully knocked on the ground, butt first, the slide will move to the rear and by action of the spring forward again, at the same time feeding a cartridge into the barrel and firing the round. Shots fired accidentally in this way have in certain instances caused great causalties.
SUMMARY OF THE INVENTION
The object of the present invention is to eliminate the drawback mentioned and to provide an automatic hand firearm where the slide can be made safe also in the forward position so that accidental movement of the slide into its rear position and loading of the gun is prevented. A further object of the invention is to provide an automatic hand firearm where unintentional forward and/or rearward movement of the slide is prevented. It is a further object of the invention to provide an automatic hand firearm where the slide may, if desired, be slowly admitted to go into its forward position so that no firing of the round takes place. Furthermore, it is an object of the invention to provide an automatic hand firearm which is provided, in addition to the conventional handle, with a particular operating handle, placed to advantage at the muzzle end of the barrel, to facilitate aiming when giving continuous fire.
Regarding the features which are characteristic of the invention, reference is made to the claims section.
The invention is based on a construction in which the operating handle has been pivoted to the body with the aid of a slide member to be turnable from its transporting position into the shooting position and to be movable in the longitudinal direction of the gun, that is in the direction parallel to the barrel. The slide member cooperates with the slide so that the slide can be cocked with the slide member and advantageously allowed to go into the forward position slowly under control by the slide member, without firing the gun. Moreover, the operating handle has been provided with at least one safety member for putting the slide on safety and for locking it in the cocked rear position and/or in the uncocked forward position with the aid of the operating handle.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
In FIG. 1 is seen an automatic hand firearm with mass obturation, i.e. the recoil force caused by firing the firearm is utilized to move the mass of a sliding mechanism into its rear firing position, comprising a gun body 1 with handle 2 and barrel 3. The slide 4 has been disposed to be movable substantially parallel to the barrel, carried by the guide groove 5, and it has been provided with a return spring 6. The gun furthermore comprises a cocking mechanism 30 and firing mechanism 7 and an operating handle 8 for cocking the slide. When using the firearm, the slide 4 is cocked in its rear position, where it is held by the cocking step 20, removable by means of the firing mechanism 7. When the gun is fired with the aid of the firing mechanism 7, the
