Abstract

Repeating rifle with repeating action via linear sliding movement of the handle (7) surrounded by the trigger hand, hereinafter referred to as the repeater handle, characterized in that the breech (4) is prestressed by a compression spring (6) positioned behind it coaxially to the barrel axis and is held in the closed state by the latter becomes.

Description

State of the art

Bolt-action rifles, the reloading process of which is carried out by a sliding movement parallel or essentially parallel to the barrel axis by means of a handle located behind the trigger unit or by means of the trigger guard itself, have been known in individual examples or small series since the end of the 19th century, but have not yet been able to establish themselves .

problem

The main problem with previously industrially manufactured weapons (Sommer & Ockenfuss) is due to the principle of the distance between the force application point on the grip (7) and the barrel axis, which results in a tilting moment when repeating in connection with the axially undefined breech (4), which causes a sluggish repetition with clamps. This effect is intensified by the stick-slip effect (“rattling effect”, constant alternation between static and sliding friction) of the movable handle (11) and by any catch devices of the breech for fixing in the end positions. A further problem is the possible risk of injury to the repeating hand due to the displaceable handle (11) by crushing the fingers or the hand in the rear end position.

The basis of the invention is now to eliminate the existing problems through a new design.

Solution

The slide (4) is loaded coaxially to the barrel axis, similar to self-loading rifles, with a pressure spring (6) at the rear in the front slide position, so that it is opened with force via the handle (7) and closed without force. This avoids the stick-slip effect that occurs more when pushing the handle (11) than when pulling it, and the repeating process is very smooth. This effect is additionally supported by guiding the handle (11) via two parallel rods (10) and mounting the carriage on them using special plastic sliding bushes.

The elimination of the risk of injury from crushing is achieved by a protective plate (18) attached to the handle (11) above the handle (7) and thus sliding to the rear.

The hammer (15) can only be triggered if the breech (4) and thus also the handle (7) are in the locked position. In order to achieve this, there are very small contact surfaces on the trigger bar (14) as well as on the trigger tongue (12) and the interrupter (13) on it, which are only a few millimeters after opening the bolt carrier when the bolt head is still safely in the bolted position due to the dead travel. This reliably prevents the hammer (15) from unlocking when the breech (4) is open.

In order to prevent unnecessary stress on the firing pin (16) from being knocked off when the cartridge chamber (3) is empty, a slide catch (19) controlled by the spring-loaded slide in the magazine (9) is also installed, which is firmly connected to the modularly exchangeable magazine well (8). is. The modularity enables a very universal adaptability to magazines (9) from different manufacturers.

Claims (7)

Repeating rifle with repeating action via linear sliding movement of the grip (7) surrounded by the trigger hand, hereinafter referred to as repeating grip, characterized in that the breech (4) is coaxial with a behind it is preloaded by a compression spring (6) positioned in relation to the barrel axis and is held in the closed state by this. Grip repeater after claim 1 , characterized in that the trigger (12) or the interrupter (13) mounted on it can only come into contact with the trigger rod (14) in the closed position such that the hammer (15) can be triggered. Grip repeater after claim 1 , characterized in that the displaceable handle (11) is mounted in two parallel, round guide rods (10). Grip repeater after claim 1 , characterized in that the displaceable handle (11) has inserted plastic bushings, which in turn are in contact with the guide rods (10). Grip repeater after claim 1 , characterized in that a protective plate (18) is mounted on the upper side of the slide, which completely covers the non-moving parts of the sliding device such as the guide rods (10) in all positions during the repeating process. Grip repeater after claim 1 , characterized in that the magazine shaft (8) is connected to the weapon housing (1) in a modular manner, i.e. detachably, and is therefore interchangeable. Grip repeater after claim 1 , characterized in that after the last cartridge (17) has been unloaded from the magazine (9) by the breech (4), in the next repeating operation a breech catch (19) prevents the breech (4) from moving to the rear, open position without removal of the empty magazine(9) or inserting a full magazine(9).
