The invention relates to a stop stock for pistols, which consists of a shoulder piece and a holding part, the pistol having a housing with a downwardly projecting at least partially hollow handle and a slide guided on the upper part of the housing, and the holding part of the stop shaft can be attached to the handle of the pistol.

If a pistol is to be used for greater distances or for quick successive shots or if increased accuracy is required, the weapon must be supported on the shooter's shoulder. Foldable shoulder rests are known for submachine guns; there they have the purpose of being folded in for easier transport. But they are always folded out for use. As a rule, they are not removable.

In the case of pistols, it is known from practice to attach the stop shaft from the outside to the handle (Mauser, Ruger) so that either guide rails are provided on the outside of the handle or even the handle is surrounded by a holder when used with the stop shaft in order to ensure a firm connection reach. The stop shaft should be connected to the pistol without play when aiming and shooting and should absorb the recoil force. In both cases this is not the case. In addition, the grip feeling is disturbed by the shaft attached to the outside of the grip, which impairs handling and accuracy. The shooter wants the grip to be able to be held securely and comfortably with or without a stop shaft.

From US Pat. No. 3,861,273 a stop shaft for pistols is known which is connected to the pistol by means of four T-shaped sliders which can be pushed into the undercuts of the pistol. The connection approximately at the height of the barrel, however, cannot absorb the overturning moment that occurs when the pistol is fired, and is therefore not usable.

A submachine gun with a shoulder rest is known from US Pat. No. 3,906,833, which in turn cannot be dismantled by means of two rods attached to the weapon.

Finally, GB 2 300 248 A discloses a stop shaft for pistols which can be pushed in the firing direction onto an adapter that can be attached to the pistol grip at the bottom. It is inconceivable that the connection between the adapter and the stop shaft would be sufficiently strong against displacement in this direction. When firing, the front part of the stop stock is subjected to full bending stress from the recoil of the pistol and its tilting moment. There is no connection between the stop shaft and the pistol approximately at running height.

It is therefore the object of the invention to design a stop shaft in such a way that it can be firmly connected to the pistol and the feel of the grip is not impaired with and without it.

According to the invention this is achieved in that the holding part has a lower and an upper strut which run approximately in the firing direction, the lower strut ending in an upwardly directed guide bar which can be inserted from below into guides in the interior of the handle of the pistol, and which upper strut connects to the upper part of the housing.

When the guide is placed inside the handle, its outside is completely unchanged, it feels like the shooter is used to. Since the grip piece is already hollow to reduce weight and to accommodate the magazine, this requires only little structural effort. Because the entire depth of the handle is available, a good stiffness of the connection is achieved. This is further improved by the fact that the upper strut connects to the upper part of the housing. In this way, it can also absorb the recoil force directly without hindering the return movement of the slide. Lanyards are not required because the recoil force is a compressive force. In addition, the two longitudinal struts, which are arranged at a vertical distance from one another, leave enough space for the shooter's hand to reach through.

The guides preferably have grooves formed in the rear part of the side walls of the handle, and the guide strip can be pushed into these grooves with its side edges (claim 2). The grooves in the side walls offer a sufficient guide width so that the guide can also absorb bending moments and, with sufficient accuracy, even side forces. The guides themselves can be profiled differently. Since the edges of the groove have to protrude inward due to the small wall thickness of the handle, they also stiffen the handle.

The arrangement of the guides in the rear part improves the use of space, since the rear rounded part of the interior cannot be used for the magazine. So can the tours

AT 410 141 B at the same time serve as a delimitation of the space formed in the interior of the handle for the magazine (claim 3), even as a magazine guide.

In a preferred embodiment, the lower and upper struts of the holding part are part of a closed reinforced zone which extends from the guide bar to the end of the upper strut adjoining the housing (claim 4). The two ends of the struts that absorb forces are thus connected to one another on the shortest path around the access opening, resulting in closed lines of force. If the stop shaft is made of plastic, the closed reinforced zone is a metal part embedded in the plastic (claim 5).

In a further development of the invention, a locking element is provided which counteracts a displacement in the direction of the guides (claim 6). This can be designed very differently. A particularly practical and beautiful solution is that the locking element is a spring-loaded ball part which engages from the inside against a recess in the rear wall of the handle (claim 7). So the grip feeling and the sight are not impaired.

The invention is described and explained below with reference to figures. They represent:

Fig. 1: The stop stock according to the invention with pistol,

Fig. 2: the stop stock according to the invention without a pistol,

Fig. 3: a section according to III-III in Fig. 2,

Fig. 4: a section according to IV-IV in Fig. 1,

FIG. 5: like FIG. 4 in a variant.

In Fig. 1 a pistol is summarized with 1 and the (cut) stop shaft with 10. The housing 2 of the pistol is of the usual shape, it has a hollow handle 3 and an upper guide part 4, which is the upper part of the housing , on which a slide 5 is guided, which (not visible) contains a barrel and a breech. A magazine 6 can be inserted into the handle 3 from below. The returned position of the carriage 5 is indicated by dashed lines and denoted by 5 '.

Fig. 2 shows a little more of the stop shaft 10; the shoulder piece 11 is cut off again. This is followed by a holding part 12 at the front, which consists of an upper strut 13, a lower strut 14 and an intermediate strut 15. These three struts 13, 14, 15 form a closed zone, approximately C-shaped and surround an opening 16 for the hand and the ball of the thumb of the shooter. Connecting struts 17, which establish the connection between the struts 13, 14, 15 and the shoulder piece 11, connect approximately as an extension of the upper and lower struts 13, 14. They can be elastic. The upper strut 13 ends in a stop surface 18. The lower strut 14 is angled at its front end and forms a guide bar 20 with a stiffening rib 21 to increase the flexural rigidity, the plate 22 merges into the lower strut 14 on a stop.

In Fig. 3, the cross section of the guide bar 20 with stiffening rib 21 can be seen better. In the exemplary embodiment shown, the cross section of the intermediate strut 15 consists of a reinforced zone 25 and a plastic jacket 26 surrounding it. The reinforced zone 25 can be a metal bracket which penetrates the struts 13, 14 and 15 and is encapsulated with plastic. If the plastic is sufficiently hard, the metallic reinforcement can also be omitted. The cross section is then simply that of the plastic jacket, the ribs 27 ensuring the flexural rigidity of the entire C-shaped closed zone.

4 is a section through the hollow handle 3. It consists of side walls 30, 31 which are connected at the front and rear by a suitably shaped circular wall 32, 33 to form a closed profile and approximately at the transition from the side walls 30, 31 to the front circular wall 32 are reinforced with a transverse wall 34. Approximately at the transition to the rear circular wall 33, reinforcements 35 with a nose-shaped cross section are provided in both side walls 30, 31. On the one hand, these together with the transverse wall 34 form the guide for the magazine 6. On the other hand, they form the guide for the guide bar 20. For this purpose, they have guide grooves 36 into which the side edges of the guide bar 20 are inserted. The guide bar 20 is pushed so deep into the handle 3 that its lower end rests on the stop plate 22.

Fig. 1 shows the pistol with the stop shaft 10 in the mounted position thus reached. In this the stop surface 18 (see Fig. 2) has reached the rear wall of the upper part of the housing 2 of the pistol. A connection or fastening is not required at this point, because

AT 410 141 Β the rigidity of the lower strut 14 and the guide bar 20 with stiffening rib 21 ensures a clean and play-free guidance of the pistol, both in the firing direction and in the transverse direction. The recoil generated during the shot acts as a compressive force directly from the upper part of the housing on the upper strut 13.

FIG. 5 shows a possibility of locking the guide bar pushed into the handle 3 in such a way that it cannot be easily pulled out. In the exemplary embodiment shown in FIG. 5, the reinforcing rib 21 is widened to form a spring housing 40 at the point of the incision. In this there is a pin 41 which is pressed outward by a spring 42 and has a ball head 43 which engages in a bore 44 in the rear circular wall of the handle 3. In order to pull the guide bar 20 out of the handle, the ball head 43 must either be pushed out of the bore 44 against spring force, or it is pushed in from the outside with a pin. For the locking, a number of other solutions are conceivable within the scope of the invention.

Overall, a lighter, stiff and handy stop stock was created that is easy to attach to the pistol and, on top of that, requires no or only minor changes to the pistol.
