Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention pertains to a handgun, particularly an automatic pistol, with a grip piece, a breech that can be longitudinally displaced relative to the grip piece, and a breechblock mechanism that can be actuated on both sides.

2. Prior Art

A handgun of this type with a breechblock mechanism that can be actuated on both sides is known from DE 100 08 979 A1. In this case, the breechblock consists of a first pivot lever that is provided with a catch element and arranged on one side of the weapon, wherein this first pivot lever is non-rotatably fitted to a pivot lever shaft that laterally extends through the weapon to the other side. A second pivot lever provided on the other side of the weapon is detachably connected to the free end of the pivot lever shaft. However, the manufacture of such a multi-piece breechblock mechanism is quite complicated. In order to install and remove this breechblock mechanism, both pivot levers must be assembled or disassembled, which is time- and labor-intensive. In addition, suitable measures must be taken in order to ensure that both pivot levers are held together in the assembled state.

SUMMARY OF THE INVENTION

The invention is based on the objective of developing a handgun of the initially mentioned type with a breechblock mechanism that can be inexpensively manufactured and easily installed.

This objective is attained with a handgun with the characteristics of claim 1. Practical additional developments and advantageous embodiments of the invention form the objects of the dependent claims.

One significant advantage of the handgun according to the invention can be seen in the fact that the breechblock lever can be manufactured quite easily from a sheet metal by means of punching and bending processes, wherein the breechblock lever can also be easily installed. Complicated manufacturing and installation steps are not required. Another advantage of the invention is that the elimination of any play between the two operating elements results in improved accuracy.

In one particularly practical embodiment of the invention, the two lateral parts are bent upwards relative to the crosspiece. The two respective lateral parts contain front sections that project forwards relative to the crosspiece and are provided with aligned through-openings for a pivot pin.

Holding and operating parts that are respectively bent outwards and downwards preferably are integrally connected to the sections of the two lateral parts that project rearwards relative to the crosspiece, wherein at least one of the holding parts is designed for engaging into a lateral slot of the breech.

A tab that causes the breechblock lever to be pressed into a raised locking position by the feeder mechanism of the inserted magazine is integrally connected to one of the lateral parts.

BRIEF DESCRIPTION OF THE DRAWINGS

Other particularities and advantages of the invention are described below with reference to a preferred embodiment that is illustrated in the drawings in which:

FIGS. 1a and 1b show a breechblock lever in two perspective representations;

FIG. 2 shows a pistol with the breechblock lever shown in FIGS. 1a and 1b, wherein the breech of the pistol is in the closed position; and

FIG. 3 shows a pistol with the breechblock lever shown in FIGS. 1a and 1b, wherein the breech of the pistol is in the open position.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

The pistol that is schematically illustrated in FIGS. 2 and 3 contains a grip piece 1 that is made of plastic or metal and a breech 2 that can be longitudinally displaced relative to the grip piece 1. This breech can be held in an open position by the breechblock lever 3 that is illustrated separately in FIGS. 1a and 1b. A barrel 4 is conventionally arranged within the breech 2.

According to FIGS. 1a and 1b, the breechblock lever 3 consists of two flat lateral parts 5 and 6 that are separated from one another and connected by a lower crosspiece 7. The two respective lateral parts 5 and 6 contain front sections 8 and 9 that project forwards relative to the crosspiece 7 and are provided with aligned circular through-openings 10 and 11 for a shaft journal or a pivot pin. The breechblock lever 3 is pivotably arranged in an insert that can be installed into the grip piece 1 with the aid of the lateral through-openings 10 and 11 and the (not-shown) pivot pin. The sections 12 and 13 of the two lateral parts 5 and 6 that project rearwards relative to the crosspiece 7 are perpendicularly bent outwards and respectively contain outwardly projecting arms with perpendicularly bent holding parts 14 and 15 and downwardly angled operating parts 16 and 17. A knurling is embossed into the outer side of the operating parts 16 and 17. An inwardly bent tab 18 is provided on the front lateral part 5 in FIG. 1, wherein said tab engages with a feed mechanism of a magazine 19 inserted into the grip piece 1 in order to raise the breechblock lever 3. The breechblock lever 3 shown in the figures can be easily manufactured in the form of a one-piece punched and bent part.

• • a. The breechblock lever 3 is arranged on an insert within the grip piece 1 in such a way that it can be pivoted between the lower position shown in FIG. 2 and the upper position shown in FIG. 3. In the lower position, the holding part 14 of the breechblock lever 3 engages into a lateral recess 20 on the upper edge of the grip piece 1. In this position of the breechblock lever 3, the breech 2 is able to freely move rearwards. However, once the last cartridge is fired, the breechblock lever 3 is pressed upwards by the (not-shown) spring-loaded feed mechanism of the magazine 19 that engages with the tab 18. As the breech 2 is displaced rearwards, the holding part 14 of the breechblock lever 3 engages into a lateral slot 21 on the underside of the breech 2 so that it is held in the open position.

After removing the empty magazine and inserting a full magazine, the breechblock lever 3 can be pressed downwards with the thumb of the right or left hand, namely with the aid of the operating parts 16 and 17 that project from the right and left side of the grip piece. This causes the holding part 14 to disengage from the lateral slot 21 such that the pistol is once again ready to be fired.
