AUTOMATIC HAND FIREARM

The present invention concerns an automatic hand firearm with mass obturation comprising a body with a handle, a barrel joined to the body, a slide with a guide and a return spring, a cocking and firing mechanism and an operating handle placed forward of the magazine, by which handle the front part of the gun can be supported during firing. Such firearms are well-known in pratice.

An important drawback of the known 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 cartrige into the barrel and firing the round. Shots fired accidentally in this was have in certain instances caused great casualties.

Is is an object of the present invention 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. Another object of the invention is to provide an automatic hand firearm having, in addition to the conventional handle, a special operating handle, placed to advantage at the muzzle end of the barrel, to facilitate aiming when giving continuous fire.

The automatic hand firearm according to the invention is characterized in that the operating handle is pivoted to the body with the aid of a slide member to be turnable from its transporting position substantially parallelling the barrel into a shooting position and movably turned out of its transporting position, that the slide member and the operating handle are movable in the direction of the barrel, that the slide can be pulled into a cocked rear position by the operating handle, and that the operating handle is provided at least with a safety member so disposed thatthe slide can be put on safety in the cocked rear position and/or in the uncocked forward position with the aid of the operating handle.

Secondary features of the automatic hand firearm according to the invention are indicated in the subclaims.

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.

In Fig. 1 is seen an automatic hand firearm with mass obturation, comprising a gun body 1 with a handle 2 and a 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 firearm furthermore comprises a cocking and firearm 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 rest 20, removable by means of the firing mechanism 7. When the firearm is fired with the aid of the firing mechanism 7, the slide is enabled to move forward, pushed by the force of the spring 6, whereat in its forward rush it takes a cartridge from the magazine, feeds it into the barrel and fires it. The recoil force from the round moves the slide into its rear position again.

As taught by the invention, the operating handle 8 has been joined to the body 1 by the aid of a particular slide member 9, this slide member being carried in the body of the firearm and being, movable substantially in the direction of the barrel. It is thus understood that the slide member 9 and the operating handle 8 are movable in the direction of the barrel 3. The slide member 9 cooperates with the slide 4 in such manner that the slide can be pulled into its cocked rear position by pulling the operating handle and therewith the slide member, and thus the slide, into the rear position. The operating handle 8 has been provided with a safety member 10 (Figs. 2-4), which has beeen so disposed that the slide 4 can be put on safety in the cocked rear position and/or the uncocked forward position with the aid of the operating handle 8.

Fig. 2 reveals the detailed construction of the operating handle 8. In the embodiment depicted, the safety member 10 consists of a shoulder comprising the bracing face of the barrel's 3 muzzle, that is the forward bracing face, 16 and/or the opposite, that is the rearward engagement face 13 having been so arranged that the slide is braced against said bracing face by mediation of said engagement face when it is substantially in its forward position and the bracing face prevents the rearward movement of the slide. In the embodiment depicted, the operating handle 8 has been pivoted to the slide member 9 to be turnable in a plane parallel to the barrel 3, and the safety member is constituted by the shoulder established on the lower end of the operating handle. In Fig. 2, the operating handle 8 has been pushed rearward and up, to parallel the barrel, so that the safety member 10 is pushed into a mating notch 25 formed on the slide, while the said forward bracing face pushes against the engagement face 13 and thus locks the slide in its forward position.

In Fig. 4, the slide 4 is in its rear position, that is in cocked position, held for instance by the cocking rest 20 (see Fig. 1). The operating handle 8 has been turned rearwards and upwards to parallel the barrel 3, against the barrel, so that the safety member 10 has been pushed into the path of movement of the slide 4, and the slide rests by its latter bracing face 14 against the rearward, latter bracing face 17 of the safety member, whereby the safety member prevents the pushing forward of the slide 4 even if the trigger were pressed. The operating handle has been provided with a locking member, for instance a spring latch, for locking the handle in the position shown in Figs. 2 and 4.

Fig. 3 illustrates how the slide is cocked with the aid of the operating handle 8. The slide member 9, which has been carried in the body 1 to be movable in the direction of the barrel 3, has been pulled backwards by the operating handle 8, the latter being connected to the slide member 9. The slide member 9 has been provided witha bracing face 15, disposed on the path of motion of the slide 4 so that the engagement face 14 of the slide rests against the slide member by mediation of said bracing face. When the operating handle 8 is pulled further rearwards, the slide member will move rearwards, thereby moving the slide further rearwards and into the locked rear position, to be held by the cocking rest 20 (Fig. 1). The slide member may thereafter be pushed into the forward position with the aid of the handle 8. When shooting the firearm, the slide member 9 is pushed into the forward position and turned forwards as shown in Fig. 5, whereby the locking member 11, that is a ferrule pivoted to the slide member by means of an axle pin 12, turns along with the operating handle and the locking shoulder 22 enters behind a shoulder formed on the body, preventing the rearwards movement of the slide member, and thus of the operating handle. The locking is released by turning the operating handle 8 rearwards, causing the ferrule to be braced against the handle and to turn therewith, opening the locking. In Figs. 3 and 5, the operating handle has been locked to the ferrule, that is to the locking member 11, with the aid of a springloaded pin 18, which enters a groove 19 provided in the ferrule. The shoulder 21 establised on the body 1 and in support of which the slide member 9 can be locked with the aid of the locking member 11, is seen in Fig. 3.

It is possible, if desired, to let the slide 4 slip forwards from its rearward position, in controlled manner, carried by the slide member 9, by moving the slide member into the rear position so that the slide rests against the slide member by mediation of the bracing surface 15 and the engagement face 14, whereafter the slide is allowed to move forwards by pressing the trigger and letting the slide member move forwards into its forward position while restraining this movement by the handle 8.

In the embodiment depicted in Fig. 6, the locking member 11 has been formed of groove-like depression 26 made on the end of the operating handle. When the handle is turned into its forward position, the part 27 of the firearm's body enters the recess 26 and locks the handle in the firing position when the handle is held in the forward position.
