Abstract

A shoulder stock for pistols, consisting of an elongated body, having a rear end that forms a first support surface for contact against a shoulder region of a shooter and having a front end that forms a hand grip for the hand of the shooter as well as a second support surface for receiving an entire reaction force of the pistol, is intended to enable the use of various handguns with differently shaped grip pieces with only one shoulder stock, with minimal effort. For this purpose, the entire hand grip is replaceable and makes it possible to use different pistols with only one elongated body.

Description

The invention relates to a shoulder stock for pistols, consisting of an elongated body whose rear end has a first support surface for contact against the shoulder region of the shooter and whose front end has a hand grip for the shooters hand as well as a second support surface for receiving the reaction force of the pistol. Known shoulder stocks for pistols are detachably fastened to the grip piece or to the housing of the respective pistol. As a result, the pistol shooter benefits from the advantages of a standard rifle, for example an increase in shooting accuracy. Such shoulder stocks are known from U.S. Pat. Nos. 8,438,771 and 4,291,482. In patent AT 410141 of the applicant, a shoulder stock is described whose lower strut engages in a guide specially created for this purpose on the grip piece, and whose upper strut forms a contact surface for the grip piece. Because the shooters hand during use only encompasses the pistols grip piece, the stability of the connection is limited by the bending stiffness of the lower strut. All these shoulder stocks share the disadvantage that their assembly and disassembly require skill and increased training. In an operational scenario, this can present a problem. Further-more, such shoulder stocks must be attached in such a way that the slide's recoil is not impeded. This either impairs the feel of the grip (see U.S. Pat. No. 8,438,771) or requires design measures on the pistol (see U.S. Pat. No. 4,291,482). Moreover, these shoulder stocks are each designed for connection with a specific pistol. From patent AT 514689 of the applicant, a shoulder stock is known which comprises a hand grip for the shooters hand and a support surface for receiving the reaction force, and the connection with the pistol is made by the shooters hand. The hand grip forms a forwardly open recess into which the contour of the rear part of the pistols grip piece fits. The free space in front of the hand grip accommodates the shooting hand, so that the shooter can encompass the hand grip together with the grip piece, which is received by the hand grip, using one hand. The grip piece and the hand grip are held together by the shooters hand, meaning that no additional connecting element and no locking mechanism are required. The disadvantage here is that the shoulder stock only fits one particular weapon. Producing various shoulder stocks for different hand firearms is not expedient due to the high tooling costs for plastic injection-molded parts. It is therefore the object of the invention to enable, with minimal effort, the use of different handguns with different grip piece shapes using only a single shoulder stock. According to the invention, the front part of the shoulder stock, that is, the hand grip area is interchangeable, with its shape adapted to the respective pistol grip. This allows the shoulder stock to be used with different weapons. In this preferred embodiment, the elongated body branches at the front into two arms, and the hand grip is a grip element attachable to the ends of the arms, with the arms and the hand grip being connected by longitudinally oriented plug pins. In this embodiment, very wide or narrow pistol grip pieces, or pistols with unusual grip shapes, can be used. The plug pins fit into an opening of the respective other part and can be secured by pins arranged transversely to the firing direction. A forwardly open recess bounded by side walls positions the pistol and provides support so that it can be quickly and securely grasped at the same time as the hand grip and brought into the in-use position. In a variant of the preferred embodiment, the hand grip in a one-piece shoulder stock forms a forwardly open recess into which an insert part can be placed, into whose front contour the rear contour of the grip piece of a pistol fits. In any event, the rear contour of the insert part corresponds to the shape of the forwardly open recess of the hand grip. The front contour of the insert part 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 part can be made of any materials, for instance also of an elastic material for damping recoil. It could be joined to the hand grip by gluing, latching, snapping in, or screwing, preferably by pins arranged transversely to the firing direction. It consists of a base extending over the entire length of the recess, of an upper hook that forms a contact surface acting in the vertical direction, and of side walls. The width of the base of the insert part corresponds to the inner clearance of the forwardly open recess of the hand grip. Below, the invention is described and explained on the basis of figures of two embodiments. These are showing: FIG. 1: A shoulder stock with pistol in the in-use position, FIG. 2: The shoulder stock in a first embodiment, FIG. 3: Its front part, enlarged and exploded, FIG. 4: The insert part
