The invention relates to a rifle stock. The invention furthermore relates to a rifle having such a rifle stock.
From DE 10 2011 010 940 A1, a rifle stock is known, which contains, as bedding for the receiver and/or barrel, a support part attached in the rifle stock. The support part comprises on the top side a support area for the support of the receiver and on its bottom area a profiling for the positive-fitting holding of the support part in the rifle stock. In this known system bedding, the support part is inserted into a corresponding recess on the top side of the rifle stock, and pulled inward by an attachment screw from beneath into the recess, and thus braced against the rifle stock. As a counter bearing for the attachment screw, a magazine frame is used, which is inserted into a deepening on the bottom side of the rifle stock. Due to various weather conditions, it is possible, however, for the rifle stock to expand or shrink, as a result of which tensioning or a clearance can occur between the rifle stock and the support part, and resulting adverse effects on the accuracy and the firing capacity can occur.
An embodiment provides a rifle stock and a rifle having such a rifle stock, which allow a bedding of a receiver and/or a barrel, which is accurate in terms of position and not influenced by changes of the rifle stock.
Other advantageous variants and advantageous embodiments are also disclosed.
In an embodiment, the support part is held via profiling not only with a positive-fitting connection in the rifle stock, but it is also connected undetachably by an adhesive connection to the rifle stock. As a result, the system or the receiver and/or the barrel are uncoupled from the rifle stock, but nevertheless connected to the latter. The profiling on the support part engages at the time of the installation in the shaft which is made, for example, of wood or plastic, and ensures an additional securing and positive-fitting connection. As a result, lateral spread is clearly reduced, and an optimized system bedding and barrel securing can be achieved for a tension-free mounting in the shaft.
In a particularly advantageous embodiment, the support part is inserted into a recess of the rifle stock and glued into the latter. This recess here can be adapted to the outer contour of the support part, so that an additional positive-fitting holding of the support part in the shaft is achieved.
The receiver and/or the barrel is (are) advantageously attached via an attachment screw to the support part. For this purpose, the attachment screw can comprise a threaded rod for engagement in a threaded bore in the receiver and a clamping surface for application against the lower application surface of the support part. In an additional advantageous embodiment, the attachment screw can comprise a threaded bore for a screw for the attachment of a magazine frame.
The profiling on the bottom side of the receiver can be formed by downward projecting guide rails which are preferably designed for pressing into the shaft. The guide rails that extend, for example, in the longitudinal direction of the support part, during the installation of the support part, push into the shaft and ensure a play-free lateral guidance. Due to the positive-fitting engagement of the guide rails in the shaft, it is also possible to achieve, without expensive preliminary work on the shaft, an offset-free and precisely repeatable connection between shaft and receiver for the precise arrangement of the receiver and/or barrel.
In an additional preferred embodiment, the preferably wedge-shaped guide rails have a cross section that converges to a tip. Due to this special shape, the guide rails press into the shaft made, for example, of wood or plastic, as a result of which a play-free positive-fitting connection is formed in an easy way.
For the support of a hollow cylindrical sleeve head of the receiver, the support area can be designed as a prism support with opposite slanted inner support surfaces on two mutually separated support rails. The support area can also be designed as a half shell or the like. In the case of a noncylindrical sleeve head, the support area can also comprise a shape adapted to the outer contour of the sleeve head or to another portion of the receiver. On the support area of the support part, one or more engagement elements for a positive-fitting engagement in the barrel can be arranged.
Additional features and advantages result from the following description of a preferred embodiment in reference to the drawing. Herein:

It is apparent from
By means of the attachment screw 14, the sleeve head 5 is secured to the support part 8 glued into the rifle stock 2. For this purpose, the attachment screw 14, which is applied with the ring-shaped clamping surface 16 on the lower application surface 15 of the support part 8, is screwed with an upper threaded rod into a threaded bore 21 on the bottom side of the sleeve head 5 and it engages with its upper end in a recess 22 of the barrel 2. The attachment screw 14 contains, in its externally hexagonal bottom part, a threaded bore 23 for a screw 24, by means of which a front part of a magazine frame 25 is attached in a lower recess 26 of the rifle stock 2.
The invention is not limited to the above-described embodiment example. Thus, it is possible to bed not only the sleeve head of a receiver designed as a chamber sleeve, but also the barrel or both, in the support part glued into the rifle stock.
