73827 5 Locking device for loading a weapon

The invention is used in biathlon rifles and other competitive rifles. It removes the old cartridge from the gun and inserts a new one.

10 The cartridge is removed and loaded in commonly used bolt-locked rifles by first opening the lock by turning the crank, which also re-tunes the lock and then removing the cartridge by pulling back on the crank. When the locking pin is pushed forward 15, the locking pin feeds the new cartridge into place and when the crank is turned to the initial position, the weapon is ready to fire again.

In addition to this, some, albeit very little, rifles have been used in which the cartridge is removed and loaded 20 using the lever under the weapon. The used cartridge is removed when the lever is pushed forward, and a new cartridge is inserted when the lever is pulled back. Tightening of the shock spring can occur during either movement of the lever. The invention relates to such a locking device. What all known models have in common is that the lever under the log is moved a long distance, even more than 100 mm. The tuning of the striker spring is also made light on a long tuning distance.

The operation of both described locks thus requires the removal of the right hand from the handle of the log and the repositioning of the right hand on the handle. All of this takes time: the mere number of seconds of the charge movement and the firing position of the firing position Due to the fact that the cat has to be detached from the logs, there is a loss of total time of up to several seconds.

The present invention eliminates this drawback because the loading movement of the lever under the log 2 73827 is so short that it is not necessary to detach the hand from the logs during the loading movement, but reloading can be performed with a simple finger movement while the weapon position remains stable. The Kek-5 invention is more closely known from the claims.

The weapon locking device according to the invention operates as follows: when the lever handle 8 under the weapon lock 25 is pushed to the front position, the lower end of the feed lever 13 pivots forward as the bearing 7 moves in the slide groove 6. The upper end of to the rear position of the locking pin 5. At the same time, the torsion lever 1 of the rear sleeve 3 pivots so that the rear sleeve 3 moves backwards in the locking pin, pulling the striker sleeve 4, which pulls the striker spike 14 back about 2 mm.

35 When the impact spike 14 rises out of the way, the old cartridge can exit and as the locking pin 15 moves forward, the new cartridge can rise out of the magazine unimpeded and the locking pin 5 pushes it into place as the lever handle 8 ti 3 73827 moves backwards.

The lever handle 8 is mounted at the bottom of the lock frame. The two-arm bearing 7 at the lower arm end of the feed lever 13 moves in a groove 6 near the lower end of the lever handle 8. Due to the shape of the lever handle bearing 12, the shaft 9, the slider groove 6 and the relative position of the lever handle 8, the loading movement is significantly reduced by about 40-50 mm. still long enough. The stroke length can be further increased by selecting the length of the upper arm of the feed lever to be greater than the length of the lower arm. Thus, the free movement of the locking pin 5 movable by means of the connecting piece 10 and the closing part 11 mounted at the end of the upper arm is made long enough for charging, even if the movement 15 of the lower end of the lever handle 8 is short. Also, due to the short movement, there is no need to detach the hand from the back of the gun. This charging movement is thus substantially accelerated. The forward movement of the lever handle 8 is light because during it the striker is not tuned, so the push can be performed with the fingers.

20

When the lever handle 8 is pulled backwards, the locking pin 5 first moves freely forwards. The movement of the lever handle 8 is then short and the movement of the locking pin 5 long.

The tuning step of the shock spring, which is heavy, only takes place 25 at the end of the pulling of the lever handle 8 backwards, when the locking pin 5 moves after free movement the last millimeters before locking. Thus, the squeezing force of the fingers can be utilized: the palm presses the lever handle 8 against the log of the lower end and at the same time the upper end of the feed lever 13 formed on the knee joint and the binding piece 10 mounted on this end straightens when the locking pin 5 locks and the shock spring tightens. The knee joint provides a strong tightening force for the shock spring. The total length of the rearward movement of the lever handle 8 corresponding to the long free movement of the locking pin 5 and the movement occurring when the shock spring 35 is tightened can thus also be short and fast. The length of the above-mentioned charging movement of less than 50 mm is completely sufficient.

Claims (1)

A locking device for loading a weapon using a lever handle (8) placed under the weapon, which, when pushed into the forward position, is pulled by the upper end of the feed lever (13) by means of a bearing-connected coupling (10) to the rear position of the locking pin (5) and its side closure (11). at the same time the torsion lever (1) of the rear sleeve (3) so that the rear sleeve (3) moves backwards in the locking pin (5) and at the same time pulls the striker sleeve (4) and the striker spike (14) backwards so that the old cartridge can exit and the locking pin (5) ) when moving forward again the new cartridge can rise out of the magazine without hindrance, after which the locking pin (5) pushes the lever handle (8) 15 backwards into the cartridge barrel, characterized in that the lever handle (8) is mounted (12) immediately at the bottom of the locking frame and (13), the bearing (7) at the end of the lower arm moves in a groove (6) near the lower end of the lever handle (8), so that the lower end of the feed lever (13) the yoke groove is relatively long, which can be further increased by selecting the length of the upper arm of the feed lever to be greater than the lower arm, so the free movement of the locking pin (5) movable via the upper arm end (10) and the closure part (11) is short with short movement of the lever handle (8) , and that the shock spring is tightened only when the locking pin (5) moves after its free movement for the last millimeters before locking, whereby the required large force 30 is obtained first by pressing the palm against the log at the lower end of the lever handle (8) and secondly by a knee-shaped feed lever (13) the upper end and the connecting piece (10) mounted on this end are currently straightened when the locking pin (5) locks 35 and the shock spring is tightened, so that the long free movement of the locking pin (5) and the short movement of the shock spring when closing can be the total movement of the lower handle (8) j guide under Tue 5 73827 50 mm, which movement can be performed without having to remove the hand from behind.
