FIREARM

Abstract

The invention relates to a firearm comprising a housing (1) with a rigid barrel (2) arranged therein, a magazine that can be mounted in the receptacle of the housing (1) and provided with cartridges (4), a closure (3) that can be moved with respect to the housing (1) in the longitudinal direction of the barrel (2) and that is used to guide cartridges (4) from the magazine into a cartridge holder (5) or for ejecting empty cartridge cases. The closure (3) is mounted completely inside the housing (1) over its entire movement path. A sear frame (6) is coupled to the closure (3) which is tensioned by means of a closing spring (7) in the direction of the front closed position of the closure (3). The invention also relates to a locking block (8) coupled to the closure (3) when the closure is in the front closed position. The locking block (8) can be tensioned by a locking spring (9) in the direction of said position, and the locking block (8) can be moved when triggering a shot through the closure (3) by compressing the locking spring (9) only for one part of the movement path of the closure (3) until the decoupling position is reached together with the closure (3).

Claims

1. A firearm comprising: a receiver; a barrel; a slide movable relative to the receiver in a longitudinal direction of the barrel in order to transfer cartridges from a magazine into a chamber in the barrel and to move cartridge casings from the chamber to an ejection port, the slide being supported inside the receiver over its entire movement path; a drive clip supported inside the receiver and coupled with the slide; a recoil spring biasing the drive clip toward a front closed position; a latch block supported inside the receiver and coupled with the slide when the slide is in the front closed position; and a latch spring biasing the latch block longitudinally forward such that, upon firing of a shot under compression of the latch spring, the latch block is displaced together with and by the slide only for a portion of the movement path of the slide until a position decoupled from the slide is reached.

2. The firearm according to claim 1, wherein the latch spring has a greater spring constant than the recoil spring.

3. The firearm according to claim 1 or 2, wherein the slide has lateral projections that extend normal to a longitudinal direction of movement and engage with respective stop faces on the latch block on movement from the front closed position to the decoupled position, and vice versa.

4. The firearm according to claim 1, wherein the latch block has bearing pins that extend normal to the longitudinal direction of the barrel and that are guided in respective slide tracks in the receiver, each of the slide tracks having a rear end portion that deviates from the direction of movement of the slide at an angle, thus moving the latch block into the decoupled position upon entry of the bearing pins into these rear end portions.

5. The firearm according to claim 1, wherein the drive clip has securing projections that, upon reaching the decoupled position, engage in corresponding recesses in the latch block during rearward movement of the slide after a shot is fired and secure the latch block during further rearward movement of the drive clip in the decoupled position.

6. The firearm according to claim 1, wherein the recoil spring is supported between a bearing portion of the drive clip and a bearing portion of the latch block.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The invention will now be described in greater detail with reference to an embodiment and the accompanying drawings, wherein

[0013] FIGS. 2 to 6 each schematically show the main components of the present invention in the different positions along the movement path of the slide, and

[0014] FIG. 7 is another schematic perspective view of a handgun with the receiver removed only on the upper side.

MANNER(S) OF CARRYING OUT THE INVENTION

[0015] FIG. 1 shows only the essential main components of one possible embodiment of a firearm according to the invention. Only a portion of the multipart receiver 1 is shown on which the parts of the latch system are mounted, the receiver as a whole having additional parts, such as the grip with magazine well, an upper cover, etc. The chamber 5 (see FIG. 7) extended forward by the rigidly mounted barrel 2 is in the upper illustrated part of the receiver portion. The slide 3 shown here in the front closed position behind the chamber 5 can move inside the receiver 1 in the longitudinal direction of the barrel 2. Grooves 19 into which wings 20 of the drive clip 6 engage are at the rear end of the slide. The drive clip 6 also extends longitudinally of the barrel 2 to a front bearing portion 17, against which the recoil spring 7 is braced.

[0016] Furthermore, a latch block 8 is inside the receiver 1 and mounted in the receiver by lateral bearing pins 12 in respective slide tracks 13. A bearing portion 18 is located at the front end of the latch block 8, and a latch spring 9 is braced between the receiver 1 and the bearing portion 18. On the other hand, the recoil spring 7 is supported between the bearing portion 17 of the drive clip 6 and the bearing portion 18 of the latch block 8. Abutment surfaces 11 are present at the rear end of the latch block 8 in the form of upwardly open hooks that cooperate with corresponding lateral projections 10 on the slide 3 and bias it toward the front closed position.

[0017] FIG. 2 shows the illustration of FIG. 1 in a side view in the locked front position. When a shot is fired, the entire subassembly consisting of the slide 3, drive clip 6, and latch block 8 is first moved rearward by the gas pressure while compressing the latch spring 9 (see FIG. 3). After a short distance, the bearing pins 12 of the latch block 8 enter the rear end portions 14 of the slide tracks 13 in the receiver 1. These end portions are inclined downward at an angle and thus pivot the latch block 8 downward into a decoupled position (see FIG. 4). As a result, the stop faces 11 disengage from the lateral projections 10 of the slide 3, and the slide 3 together with the drive clip 6 now move further rearward while only compressing the recoil spring 7 (see FIG. 5).

[0018] During this rearward movement, lateral securing projections 15, here in the form of lateral ribs on both sides of the drive clip 6, slide into corresponding grooves 16 (see FIG. 1) on the latch block 8 and thereby hold the latch block 8 in the downwardly pivoted-out decoupled position.

[0019] After reaching the rearmost end position (see FIG. 6), the slide 3 is moved forward again by the recoil spring 7 acting on the driving bracket 6, a new cartridge 4 also being taken out of the magazine by the slide. After the slide 3 and drive clip 6 have passed the decoupled position of the latch block 8, the securing projections 15 emerge again from the corresponding recesses 16 on the latch block 8 and release it. Due to the force of the latch spring 9, this is now forced forward and upward along the slide tracks 13, engages with its stop faces 11 on the lateral projections 10 on the slide 3, and pulls the slide 3 back into the front closed position, whereby the position according to FIG. 1 is reached again.

[0020] FIG. 7 shows another perspective view of one possible handgun with a latch system therein. Only the upper receiver cover has been removed for the sake of better visibility. In this illustration, the slide 3 is in the rear end position according to FIG. 6. It can be clearly seen that the entire action can be easily accommodated inside the receiver 1, thus enabling the receiver 1 to have a largely closed design without external moving parts, which is why the firearm according to the invention has a particularly low susceptibility to malfunctions and contamination. Due to the small number of moving parts in the action, the firearm according to the invention has a low susceptibility to malfunctions and, due to the rigidly mounted barrel, a high level of accuracy.
