Previously known weapon constructions in which the barrel is adapted to be movable are disclosed in German Patent Publication Nos. 79090, 2085 * 10, 889568 and * 102 * 177; Norwegian Patent Publications ** 307 and 83936; English Patent Nos. 5,284 and 1,0222 and U.S. Patent Nos. 3,088,378 and 3,892,082.

The loading slide is used in semi-automatic and fully automatic firearms, especially automatic pistols.

In previously known weapon designs, loading occurs as the barrel moves forward such that the gun mechanism releases a new cartridge from the magazine or magazine or moves the new cartridge elsewhere behind the barrel, leaving the cartridge in the barrel return movement 2 63488 in the cartridge housing and pushing the barrel as it moves forward behind the barrel of the cartridge, from which it enters the cartridge housing in the return movement of the barrel, or so that as the barrel moves forward it strikes a separate feeder which pushes the cartridge behind the barrel from where it enters the cartridge housing. In this case, the cartridge cannot be pushed into the cartridge housing by the feeder. Thus, in the previous weapon structures, the loading does not take place in a continuous motion from the magazine or magazine to the cartridge case, which is a good side of conventional weapons.

It is an object of the present invention to provide a loading slide arrangement for an automatic weapon in which loading can take place continuously from the magazine, magazine or belt in whole or in part in the cartridge housing, and the invention is mainly characterized in that the slide is fixedly movable longitudinally between the slide and the slide. there is one or more springs which tend to bring the slide against the end of the barrel cartridge housing and that the sliding latch controlled by the forward movement of the barrel and the spring acting on the slide latch is adapted to control the movement of the slider a retaining slide latch against the spring force of this spring to allow the charging slide to move towards the rear of the barrel.

The loading slide according to the invention makes it possible for the handle of the pistol to be shaped so that the longitudinal axis of the barrel is inside a support surface against the palm of the shooter. This reduces the upward turning effect of the recoil. In addition, the total length of the pistol and rifle-caliber weapons is considerably smaller than at present, with the same barrel length. Because the barrel and loading slide move inside the body, the size of the gun is made small without the risk of the moving parts hitting the shooter's hands. Because the movement of the moving parts is two-stage, or the forward movement of the barrel and the movement of the skate are consecutive in time, the characteristic velocity of the fully automatic weapon decreases and the controllability of the weapon improves. It is safe to fire with a weapon containing the invention, since the cartridge rests on a fixed body of the body at the moment of firing. When loading, the loading slide pushes the cartridge partially or completely into the cartridge housing before the return movement of the barrel, which reduces the supply fault • finally 11 is reduced, as it reduces the number of parts. Conventional magazines and, in general, detachable magazines can be used in the weapon.

It has not been possible to combine the above features sufficiently, for example, in the case of weapons with a feeder, space is required behind the barrel, which either prevents the advantageous shape of the handle from recoiling, or prevents the use of conventional magazines.

The invention will become more apparent from the following description and the accompanying drawings, in which Figures 1 to 4 show a part of a weapon according to the invention in a side sectional view at different stages of operation, Figure 5 shows section 1 from Figure 1, Figure 6 shows section 2 from Figure 2, BB shows Figure 7 cross-sectional view of equipping a weapon with two spindles, Fig. 8 shows a cross-sectional view of equipping a weapon with one • spindle, Fig. 9 shows a side view of the end of a spindle provided with a surrounding sleeve when the sleeve is cut, Fig. 10 and around this spring, Fig. 11 shows a section taken at CC from Fig. 10, Fig. 12 shows a side view of the weapon handle, and Fig. 13 shows the arrangement of the weapon of Figs. arrangement.

According to Figures 1-4, the weapon comprises a body 7 with respect to which there is a longitudinal! in its direction-movably arranged barrel 1. The barrel 1 is pressed backwards by a return spring 3 arranged around the barrel 1. The barrel 1 has at its rear end above the cartridge housing 10 in the lug Ib bores for the slides 9 of the slider 9.

The slider 9 is fixed to the barrel 1 by means of slider spindles 11 in its longitudinal direction, and between the slider 9 and the barrel 1 there is one or more springs 2 which tend to bring the slider 9 against the end 10 of the cartridge housing 10. The sliding latch 8 rotatable by the bearing pin 8c, guided by the forward movement of the barrel 1 on the one hand, and the spring 8b acting on the slide latch 8, is adapted to control the movement of the slider 9 so that at the end of the barrel 1 f 4 63 * 88 to open the sliding latch 8 holding the loading slider 2 against the spring force of this spring 8b to allow the loading slider 9 to engage at the rear end of the barrel 9.

The weapon in Figures 1-4 operates as follows.

In Figure 1, the weapon is ready to fire. When the striker hits the detonator of the cartridge 5, the cartridge is triggered. When the cartridge 5 is triggered, the pressure of the gunpowder and the friction between the bullet and the barrel 1 cause the barrel 1 to move forward inside the fixed body 7. The barrel 1 tensions forward as it moves the slide springs 2, because the slide 9 does not move with the barrel 1 at this stage, because the slide latch 8 prevents this movement. At the same time compressing the barrel 1 return spring 3 ·

The empty sleeve 4 (Fig. 2) is removed from the weapon after the barrel 1 has moved a distance of about the length of the sleeve. As the barrel 1 moves forward over the length of the cartridge 5, the inclined surface 6 of the barrel 1 opens the slide latch 8 mounted on the shaft 7 of the weapon body 7c, as the surface 6 lifts the front end of the slide latch 8 9 is released. In this case, the slide springs 2 push the slide 9 forward and the slide detaches the uppermost cartridge 5 from the cartridge 14 and pushes it further at least partially into the cartridge housing 10 (Fig. 3). At the latest during the return movement of the barrel 1 (Fig. 4), the loading slide 9 is pushed onto the rear end of the barrel 1, closing the cartridge housing 1Q. The barrel 1 and the slide 9 stop against the body 7 in the position according to Fig. 1, whereby the cartridge 5 rests on its base on the slide 9 · Next the spring 8b of the slide latch 8 lifts the rear end of the slide latch 8, thus locking the slide 9 As shown above, and as can also be seen from Fig. 7, there may be two parallel spindles 11 guiding and moving the slide 9 in parallel. However, the structure can also be made as shown in Fig. 8, in which the slide 9 is guided and moved by only one slide spindle 11.

In weapons where the removal of the cartridge 5 from the magazine 14, magazine or belt requires a great deal of force, a sleeve 16 is fitted to the front end of the spindle 11 surrounded by the slide spring 2, as shown in FIG. The barrel 1 strikes forward as it moves with the lug Ib onto the sleeve 16 and thus forces the loading slide 11 forward through the sleeve 16. The width of the gun can be small

Claims (3)

63488 5 by placing the return spring 3 * of the barrel 1 around the spring guide 17 fixed to the barrel 1 and the slide spring 2 with its slide spindles 11 inside the spring guide 17 according to Figs. The preferred shape of the handle and the use of a conventional magazine can be combined by shaping the handle in pistol applications as in Figure 12 so that the extension 18 of the longitudinal axis of the barrel 1 clearly fits inside the support surface 13 of the weapon handle 12. The drawer lh is placed on the handle. The characteristic rate of fire of a fully automatic weapon can be reduced, as in Fig. 13, by locking the barrel 1 in its forward position on the latch 15 of the barrel 1.
