Interchangeable and adjustable stock for all types of rifles,

especially for hunting rifles

The present invention relates to an exchangeable stock for rifles of all types, but in particular for hunting rifles.

As is well known, the stock of a rifle is that part of the weapon that is supported against the shooter's shoulder. So he must be suitably designed and shaped so that, in addition to comfortable support, the rifle can be put on quickly and safely, for example, when moving from the wearing position to the Target and shot position to ensure.

If one also takes into account that the butt of a rifle is manufactured in series according to mean values and standard dimensions If specifications are made, the shaft comes first The task of adapting the weapon to the physical characteristics of the user as much as possible. In other words, the stock is the component through which a rifle is shaped to fit the body.

According to the current state of the art, these are usually

Shaft ends made in one piece from a suitable material attached to the piston by conventional means} the shape and strength of each shaft depend on it the physical conditions of the average user and the type of use for which the rifle is intended.

However, if, for example, a shooter has other than the usual physical conditions and / or if the rifle is to be used for a purpose other than that for which it was originally intended (other sporting discipline), or If a stock extension or shortening is desired in a rifle, then according to the known state of the art, the Existing shaft or the shaft cap can be replaced by corresponding parts with a different strength or thickness.

Replacing the shaft in this way is a lengthy and labor-intensive process, which sometimes presents considerable difficulties prepared, especially when only a more or less small number of replacement stocks are available for a rifle stands.

According to the current state of the art of the rifle stock, this is a major disadvantage, the main purpose of which is to remedy it present invention is.

This object and further objects explained in more detail in the following description are achieved by a shaft according to the invention for rifles of all kinds, but especially for hunting rifles, in that the following features are provided:

- a base plate attached to the free piston end ,

- a butt cap movably connected to the base plate by at least one adjusting screw, one end of such a screw being firmly connected to the butt cap and the other end engaging adjustably in a threaded seat embedded in the base plate,

- Guide parts for moving the butt plate against the base plate,

- resilient elements between the butt plate and the base plate, to counteract the displacement of the butt plate in the direction of the base plate.

According to a further feature of the rifle stock according to the invention, the length of the entire circumference of the butt plate is running edge is provided which, together with the base plate, forms a recess in which the shaft cap is movably guided.

The resilient elements provided between the base plate and the shaft cap preferably consist of an insert elastically deformable material, the outer contour of which essentially coincides with the contour of the edge and its thickness in the is essentially equal to the depth of the recess for receiving the shaft cap.

Further features and advantages associated therewith emerge from the following description of an exemplary embodiment of an invent appropriate rifle stock, which is shown in the attached drawings. Show it:

1 shows a sectional drawing of a rifle stock end, the components of which according to the invention are shown individually,

Fig. 2 is a sectional drawing of the shaft end of Fig. 1, the is attached to the free butt end of a rifle and

Fig. 3 is a perspective view of one in its inventive Components dismantled the shaft end from the preceding figures immediately before their attachment on the free butt end of a rifle.

In the figures, the piston neck or the end of the shaft is of a rifle, in particular a hunting rifle, denoted by 1

net, to which the shaft end according to the invention, designated in its entirety by 2 in FIG. 2, is attached.

The end of the shaft consists of a base plate 3, for example fastened with wood screws 4, 5 via through holes 6 and 7 let into the base plate 3 at the free end of the piston will.

This base plate 3 is over its entire circumference with a Edge 8 is provided which, together with the base plate 3, forms a recess 9, the bottom of which is denoted by 9a in FIG. 1 is.

The shaft end according to the invention also consists of a shaft cap 1O ₍ the outer contour of which follows the contour of the inner wall of the recess 9, from which the shaft cap 10 is movably received Butt cap 10 is guided through its outer circumference 11, which is aligned with the inner wall of the recess 9, during this Verstrllvorgangs.

An insert 12 made of elastically deformable material, for example Rubber, is located between said base plate and the butt plate 10 to prevent undesired displacement of the same to dampen towards the base plate 3 in a suitable manner, as will be explained in more detail in the following description will.

The contour 12a of the insert 12 corresponds to the contour of the inner wall of the recess 9, the thickness of the insert 12 corresponds essentially to the depth of the recess 9 from which the insert 12 is to be completely received.

To adjust the butt plate 10 relative to the base plate 3, two adjusting screws 13, 14 are preferably used, the one end freely adjustable in the corresponding, in the

Butt plate 1O attached seats 15, 16, and with the other f! End in corresponding thread in the base plate 3

's * desitze 17, 18 intervene. Of course, the | ( elastically deformable insert 12 with corresponding openings f | 19, 20, through which the screws 13, 14 pass through leads to be. H

According to a preferred embodiment of the invention The shaft is the base plate with two identical projections provided with through bores 23, 24 in the axial direction 21, 22 equipped, in the widenings 25, 26 corresponding nuts (not shown) are attached, which form the threaded seats 17, 18 for the screws 13, 14. The projections 21, 22 simultaneously form a stop for the correct assembly of the base plate 3 on the free piston end 1.

The shaft cap is adjusted by acting on the screws 13 and 14 in a similar or different manner 10 brought about against the base plate 3, with displacements that take place in the direction of the base plate 3, by the elastically deformable insert 12 is counteracted. It appears Obviously, a rifle stock designed according to the invention with its from the description and from the drawings The resulting construction and effect properties have the twofold advantage, the shaft length of a To be able to change the rifle and at the same time allow a substantial damping of the recoil when firing a shot. The possibility of changing the piston length by adjustable displacement of the butt cap 10 in relation to the Base plate 3, which can be made easily and without expenditure of time by the shooter himself, consequently allows a Adjustment of the butt length to the different prerequisites for "putting on" the weapon, which are given from case to case.
