Shoulder stock for handguns

Abstract

A shoulder stock for pistols consists of an elongate body (5), the rear end of which forms a first supporting surface (6) for bearing against the shoulder region of the shooter and the front end of which has a handle (9) for the hand of the shooter and also forms a second supporting surface (16) for absorbing the entire reaction force of the pistol, and is intended to make it possible for various handguns with differently shaped grips (2) to be used with just one shoulder stock (5) with little effort. For this purpose, the entire handle (31) is exchangeable and makes it possible to use different pistols (1) with just one elongate body (5).

Description

[0001] Stock for handguns

[0002] The invention relates to a stock for pistols, consisting of an elongated body, the rear end of which has a first support surface for engagement with the shoulder region of the shooter and the front end of which has a handle for the shooter's hand and a second support surface for absorbing the reaction force of the pistol.

[0003] Common pistol stocks are detachably attached to the grip or receiver of the respective pistol. This provides the pistol shooter with the advantages of a standard rifle, such as increased accuracy. Such stocks are known from US Pat. Nos. 8,438,771 and 4,291,482.

[0004] The applicant's patent AT 410141 describes a buttstock whose lower strut engages with a specially designed guide for the grip, and whose upper strut forms a contact surface for the grip. Because the shooter's hand only grips the grip of the pistol during use, the stability of the connection is limited by the flexural rigidity of the lower strut.

[0005] All of these buttstocks have the disadvantage that their assembly and disassembly require skill and considerable training. This can be problematic in the field. Furthermore, such buttstocks must be mounted in such a way that the slide's recoil is not obstructed. This either impairs the grip (see US 8,438,771) or requires structural modifications to the pistol (see US 4,291,482). Furthermore, these buttstocks are each designed for connection to a specific pistol.

[0006] From the applicant's patent AT514689, a shoulder stock is known that has a handle for the shooter's hand and a support surface for absorbing the reaction force. The connection to the pistol is established through the shooter's hand. The handle forms a recess open at the front, into which the contour of the rear part of the pistol's grip fits. The free space in front of the handle accommodates the firing hand, allowing the shooter to grasp the handle together with the grip, which is held by the handle, with one hand. The grip and grip are held together by the shooter's hand, thus eliminating the need for any additional connecting element or latch.

[0007] The disadvantage is that the buttstock only fits a specific weapon. Producing different buttstocks for different handguns is not practical due to the high tooling costs for plastic injection molded parts.

[0008] It is therefore the object of the invention to enable the use of various handguns with different grip shapes with only one stock at low cost.

[0009] According to the invention, the front part of the buttstock, i.e. the handle area, is interchangeable, with its shape being adapted to the respective pistol grip. This allows the buttstock to be used with various weapons. In this preferred embodiment, the elongated body branches into two arms at the front, and the handle forms a grip section that can be attached to the ends of the arms, with the arms and handle being connected to one another via longitudinal plug-in pins. In this embodiment, very wide or narrow pistol grips or pistols with unusual grip shapes can be used. The plug-in pins fit into an opening in the other part and can be secured by means of pins arranged transversely to the direction of fire. A recess bordered by side walls and open at the front positions the pistol and provides support so that it can be quickly and securely grasped with the handle and brought into the position of use.

[0010] In a variant of the preferred embodiment, the handle of a one-piece shoulder stock forms a recess open towards the front into which an insert can be inserted, the front contour of which fits the rear contour of the grip of a pistol. The rear contour of the insert corresponds in any case to the shape of the forward-open recess of the handle. The front contour of the insert corresponds to the grip shape of the respective weapon. Thus, the shoulder stock can be used with different weapons by selecting and exchanging a small part. The insert can be made of any material, for example an elastic material to dampen recoil. It could be connected to the handle by gluing, locking, snapping, or screwing, preferably by means of pins arranged transversely to the direction of fire.It consists of a base extending the entire length of the recess, a hook at the top forming a vertical stop surface, and side walls. The width of the base of the insert corresponds to the inner width of the handle's open-front recess.

[0011] The invention is described and explained below with reference to two embodiments. They show:

[0012] Fig. 1: A stock with pistol in the position of use, Fig. 2: The stock in a first embodiment, Fig. 3: The front part thereof, enlarged and exploded, Fig. 4: The insert part in side view, Fig. 5: The same in plan view, Fig. 6: The same seen from behind, Fig. 7: The same in section according to AA in Fig. 5, Fig. 8: The same seen from the front;

[0013] Fig. 9: The stop shaft in the preferred embodiment, exploded, Fig.lO: A longitudinal section along AA in Fig. 9, Fig.ll: An axonometric view of Fig. 10.

[0014] In Fig. 1, a pistol is designated 1 and a stock is collectively designated 5. The pistol's grip is designated 2, its barrel slide 3, and the trigger 4. The stock 5 is an elongated injection-molded part made of a suitable plastic with reinforcing ribs, which forms a first support surface 6 at its rear end for engagement with the shooter's shoulder region. Towards the front, it branches into two struts 7, 8, the ends of which merge into a handle 9.

[0015] The two arms 7,8 and the handle 9 surround a free space

[0016] 10 for the shooter's hand, which alone holds the handle 9 and the grip 2 of the pistol together

[0017] In Fig. 2 the stop shaft 5 is shown with the inserted part attached. In Fig. 3 it is shown enlarged with the inserted part removed.

[0018] 11. The upper strut 7 has a flattened portion 12 at the top to create clearance for the recoiling barrel slide 3. The handle 9 forms a recess 13 that is open toward the front and has a rearward extension 14 at the top. The horizontal section through the recess can be rectangular. An insert part 11 is positively inserted into this recess 13.

[0019] (Fig. 2). The rear contour of the insert part 11 corresponds in any case to the shape of the forwardly open recess 13, 14 of the handle 9. Its front contour corresponds to the rear contour of the grip 2 of the respective pistol; it forms a second support surface 16. The insert part 11 has at its upper end a rearward extension 17 which extends into the extension 14 of the recess 13 of the handle 9 and thus facilitates the vertical positioning of the insert part 11. For the secure connection of the insert part 11 to the handle 9, bores 18, 19, 18', 19' for pins, in particular roll pins 20, are provided in the two parts, arranged transversely to the firing direction. The bore 18 is approximately vertical and the bore 19 is horizontal.

[0020] In general, the front refers to the side facing the target and the back refers to the side facing the shooter.

[0021] In Figs. 4, 5, 6, and 8, the insert part 11 can be seen from the side, from the front, from the rear, and from above; in Fig. 7, it is shown in section. The recess 13 of the handle 9 and its extension 14 can be rectangular, U-shaped, or oval in cross-section. Depending on the shape of the recess 13, the rear contour of the insert part 11 is formed by a base 24 with the extension 17 at the top and a tab 25 on each side. The tabs 25 enclose the grip 2 of the pistol 1 and provide lateral support.

[0022] The insert part 11 can be easily replaced in two steps after removing the roll pins 20. This allows a different insert part 11 to be used for other pistol models.

[0023] Fig. 9 shows the preferred stop shaft 30 and the handle 31. In its basic form, the stop shaft 30 corresponds to that of the first embodiment, but the arms 37, 38 have free ends to which the two curved pieces 40, 41 of the handle 31 are attached.

[0024] In Fig. 10 and Fig. 11, it can be seen that pins 42, 43 at the ends of the arms 37, 38 fit into corresponding recesses 44, 45 of the handle 31. Cylindrical pins 49 in transverse bores 50 serve for securing.

[0025] The handle 31 is a bow. It consists of an approximately vertical base 54, against which the shooter's ball of the hand rests at the rear, i.e., outside, and curved sections 40, 41 adjoining it at the top and bottom, and side walls 57, which form a recess 51 open to the front. Its shape corresponds to that of the rear part of the grip (2) of the respective pistol. The recesses 44, 45 are located at the ends of the curved sections 40, 41, but can also be located at the ends of the arms 37, 38.

[0026] In Fig. 11 it is indicated that by having differently shaped handles 31 available the use of different pistols is possible.

[0027] It is within the scope of the invention that the above technical solutions can also be applied to revolvers and submachine guns.
