Handgun

The invention "relates to a handgun in general and in particular the formation of the bolt of such weapons.

In known handguns with a fixed barrel, the disadvantage arises that an adjustment is made by hand before firing must do on the weapon in order to prepare it for the shot, so that the pressure can be counteracted during the explosion is generated by the gunpowder, so that the breech block or the Versohlußkammer during the Bücksohlagea is not destroyed, and to facilitate ejection of the cartridge case.

The invention has the task of addressing this disadvantage overcome and create a handgun with which one can repeatedly close heavy or light cartridges, with a considerable reduction in setback in comparison to known handguns is achieved as well as a simple and safe ejection of the cartridge case

Essentially, the handgun according to the invention provided that they have a separate bolt head from the locking bolt with a loose spring lying between these parts.

! 09824/0002

This spring is designed in such a way that it performs the following functions:

a) The spring causes the bolt head to hit the bolt head elastically and thus dampens the kickback j

b) the spring allows an automatic adjustment of the solution of the locking system in that a more or less long Delay in resolution in relation to the various, of pressures generated by various cartridges;

o) the spring causes the ejected cartridge case and the reloading of the weapon by its expansion causing the entire system to move backwards Locking bolt and bolt head causes

In the following, the invention is used to explain further details and features explained on an exemplary embodiment with reference to the drawing. In the drawing showsι

the spanking bolt being in the fire position is located;

FIG. 3 shows a view corresponding to FIGS. 1 and 2, at which of the locking bolts is in the position in which the bolt head is released (kickback).

Reference is first made to FIG. The locking frame or the locking housing 7 shows a "movably arranged inside" bolt head 1 and a locking bolt 9> between which parts a helical spring 10 lay loosely. The bolt head 1 and the locking bolt 9 each have an axial bore 12 and 13 through which the firing pin 14. The bolt head 1 also has a seat 15 with a rounded end, in which seat engages the correspondingly rounded end 4- of a rod 3. At the other end, the rod has a foot part 5 with four flat surfaces 16, 17, 18 and 19, the function of which is explained below ₀ The surface 16 serves to interact with an inclined surface 6 in the frame 7 »The surface 17 of the foot part 5 serves to interact with a surface 20 in a recess 21 in the lower part of the locking bolt 9 o the surface 18 cooperates with a surface 22 in the cavity 21 of the locking bolt 9 and the surface 19 cooperates with a surface 8 which is located in the hollow space m 21 of the bolt -9 is formed »The j trigger hammer is shown at 23 and the cartridge chamber at 24.

In the position shown, the bolt head 1 holds a cartridge 2 in the cartridge chamber 4 by means of the rod 3, which acts as a push rod and protrudes with its rounded end M- into the rounded section of the seat 15. At the other end, the surface 16 is supported against the inclined plane 6 in the housing. The weapon is now ready to fire "

After the shot, the entire weapon suffers the familiar kickback because of the pressure developed in the cartridge 2 and the shutter frame 7 suddenly moves backwards while the mass of the movable bolt 9, which is not formed in one piece with the weapon, the shot thereby -

10982W0002

counteracts that the impact compresses the spring 10 and thereby dampens and delays the recoil of the entire locking system for a more or less long time depending on the powder charge. During this process, the foot part 5 of the rod 3 is constantly in contact with the inclined surface 6 to the frame 7 and is held in this position by the engagement of surface 19 with the surface 18 in the cavity 21 of the locking pin "as a result, the bolt head is held sealed against the cartridge chamber 24, as shown in Figure 2 _e ersihtlich

When the spring 10 because of the blow through the mass of the locking bolt 9 is compressed to a predetermined force during the setback, for which it is calibrated was, this spring pushes the locking bolt 9 to the rear with slight support from the base discharge, the strikes with its surface 22 against the surface 18 of the foot part 5 of the rod 3, whereby the surface 17 on the obliquely inclined Surface 6 slides in the frame until surface 17 of the foot part 5 with the surface 20 on the locking bolt 9 (see Figure 3) "engages" and thus the push rod 3 is disengaged with the frame 7 takes. The bolt head 1 now follows partly because of the still lasting kickback effect and partly due to the explosion gases the locking bolt 9 in its rearward movement until the locking bolts and the bolt head pushes the existing movable unit against the rear stop of the locking frame or housing 7, thereby causing the cartridge case to be ejected normally and easily.

Obviously, the invention can be applied to handguns Use for hunting as well as for military use. All details presented are relevant to the invention of Meaning.

Patents Handgun, characterized in that that the bolt head from the locking bolt, a spring is separated, which resiliently absorbs the impact of the bolt head against the locking bolt and thus the kickback dampens, which spring also automatically opens the locking system depending on the pressure the explosion gases are delayed and, when they are released, the ejection is delayed when the bolt and bolt head go back the cartridge case and reloading 2o handgun according to claim 1, characterized in that a push rod at the rear at one end when the breechblock is ready to fire on the bolt head and on the other end firmly in the bolt housing as well rests on at least one point on the locking bolt 3. Handgun according to claim 2, characterized in that the stop on the lock housing for the rod is an inclined surface and that at the foot of the rod there is a section which is in engagement with the inclined surface and that the locking bolt also has a stop with an inclined surface which has a second surface at the foot of the push rod: is engaged. 4. Handgun according to claim 3 »characterized in that the engagement with the lock housing and the locking bolt serving end of the bumper has a third surface which is arranged at a distance from that surface, soft abuts against the inclined surface in the housing, which third surface is designed such that it rests against a stop can come on the locking bolt, which is opposite the inclined stop on the locking bolt.
