Description

The subject of the invention is a length-adjustable butt plate with integrated recoil dampening for shoulder-supported handguns in the version as long weapons, in particular in the version as hunting and sporting weapons.

A butt plate with integrated recoil absorption, but without adjustment of the effective length of the butt plate, is, for example, the subject of US 10 317 165 B2 known. The buttplate shown there is acted upon in the buttstock by a fluid damper, the cylinder housing of which is supported in the buttstock and the piston rod of which is supported on the buttplate in order to achieve damping of the buttplate by the fluid damper. The disadvantage of this arrangement, however, is that the length of the buttstock cannot be adjusted. Since the support of the damping piston rod on the buttplate always remains the same, it is not possible to adjust the length of the buttplate in the buttstock. Only the damping force can be adjusted.

With the US 7,762,018 B1 an arrangement is known in which the setting length of the buttstock can be adjusted and fixed. However, this arrangement does not have any butt plate cushioning.

With the US 10,578,394 B2 A damping of a buttplate has become known, which also works with a liquid damper, but in which the adjustment of the shaft length of the buttstock is possible by inserting adapter plates, which means a complicated and very difficult to operate adjustment of the buttstock length.

With the US 7,762,018 B1 A length of the buttstock length that can be adjusted using locking means is known, but there is no damping.

The invention is based on the US 10 317 165 B2 the task is based on the butt plate on the buttstock of a weapon, especially a hunting weapon To develop a sporting weapon in such a way that the butt plate is dampened while at the same time the length of the buttstock can be adjusted.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

A preferred feature is that the damping unit is integrated in the length adjustment unit for adjusting the butt plate.

This has the advantage that a very compact, operationally reliable and protected against contamination design is achieved and the elements of a damping unit and a length adjustment device are arranged in a single assembly coaxially nested within one another in the buttstock housing, which is not known from the prior art.

The preferred feature here is that the butt plate is guided in a dampened manner in the buttstock housing so that it can be moved longitudinally and locked. This ensures that the damping of the butt plate is integrated in the length adjustment device in the buttstock housing and the damping unit always takes part in the event of a change in length in the length adjustment device, so that the damping unit provides consistent damping regardless of the length adjustment device.

Coping with this combination task was associated with great difficulties, because it was necessary to integrate the damping and length adjustment device in the buttstock housing in such a way that the butt plate is, on the one hand, displaceably and lockably mounted in the buttstock housing and, on the other hand, to connect the damping device with this length adjustment device in such a way that that the damping of the butt plate is always maintained regardless of the length setting.

For this purpose, it is preferred if an axial extension of the buttplate (more precisely: the buttplate receptacle connected to the buttplate) is an axial cylindrical piston extension of reduced diameter pointing in the firing direction is designed, which is accommodated coaxially displaceably by the length of the damping play in a buttstock-side adjusting sleeve with a first larger diameter, the adjusting sleeve being coaxially displaceable and fixable along the length of the adjusting play in a buttstock housing-side guide sleeve with a second larger diameter.

The coaxial integration of the damping device in the length adjustment device ensures that the damping is always present regardless of the set length of the length adjustment device.

If the coaxially interlocking sleeve parts of the damping device and length adjustment device are referred to as "cylindrical", this is only to be understood as a preferred embodiment. The coaxially interlocking parts mentioned can also have other cross-sectional shapes instead of the cylindrical cross-section, such as. have oval, triangular, rectangular, square or diamond cross-sectional shapes

This means that the damping and length adjustment device of the butt plate in relation to the buttstock housing consists of coaxially interlocking and mutually displaceable - preferably - cylindrical sleeves. The cylindrical piston extension of the buttplate (more precisely: the buttplate receptacle) is supported by an energy accumulator arranged on the front end face on the inner end face of the buttplate-side adjustment sleeve, which in turn is accommodated in a fixed outer guide sleeve which is fastened in the buttstock housing and can be displaced by the adjustment length forms the bearing unit for the aforementioned two movable, interlocking sleeve parts.

This has the advantage that for the first time a combination of two coaxially running sleeves on the stock cap side is realized, between which the damping device acts, while the outer of the two sleeves is accommodated in a length-adjustable guide sleeve on the buttstock housing side.

It is particularly advantageous that the damping and length adjustment device is arranged in the central and - preferably centric - guide part - the piston shoulder - for the longitudinal guidance of the butt plate in the butt stock. On the one hand, this results in a space-saving structure and, on the other hand, excellent properties for the sliding guidance of the butt plate in the buttstock. This ensures that the butt plate can be moved smoothly and without tilting in the butt stock. The adjusting sleeve used for longitudinal guidance in connection with the piston extension is preferably arranged in the butt plate receptacle and engages in an associated axial longitudinal bore in the buttstock and is guided there in a displaceable and fixable manner.

In another embodiment of the invention, however, it can be provided as a kinematic reversal of the previously described arrangement that the central piston extension with the associated adjusting sleeve is arranged on the butt stock and engages in a central central bore in the butt plate receptacle and is guided there in a displaceable and fixable manner. The damping and length adjustment device is then also arranged in the piston extension on the buttstock side and fulfills all of the functions described in connection with the arrangement of the piston extension in the butt plate receptacle.

It can also be provided that not only the piston extension - which accommodates the damping and length adjustment device - is present as a guide device for the longitudinal guidance of the buttplate receptacle in the buttstock, but also further longitudinal guide elements or damping elements acting parallel to the piston extension are arranged between the buttplate receptacle and the buttstock .

It is also preferred if the length adjustment is carried out in the form of a self-locking toothing. A toothing is arranged on the outer circumference of the adjustment sleeve on the buttplate side, which interacts with a counter-toothing on a locking element fixed to the housing (=buttstock housing side). The locking element is designed to be spring-loaded and pivotable on a pivot bearing fixed to the housing and engages with it its mating teeth on the teeth on the outer circumference of the adjustment sleeve on the butt plate side. It is preferred if the recoil force acting on the butt plate when the shot is fired exerts a closing moment on the interlocking teeth in order to form an additional safety element as a safeguard against unintentional displacement of the butt plate, which has a fixed length.

It is particularly preferred if the length adjustment with said counter-toothing can be triggered by a hand-operated actuating element, which is designed as a swivel button or push button and with a suitable spring arrangement is able to disengage the counter-toothing of the actuating element from the toothing on the outer circumference of the To bring the adjusting sleeve or - conversely - to bring it into engagement with a spring load.

It is preferred if the actuation button is arranged on the lower surface of the buttstock and - as shown - is designed as a swivel button or as a push button, which is locked in the rest position in order to provide security against unintentional actuation. The advantage here is that, when arranged on the underside of the buttstock, a particularly simple operation of the length adjustment is possible because when the actuating element is actuated, the counter-toothing of a locking element firmly connected to the actuating element is disengaged from the toothing of the adjustment sleeve in the buttstock housing and so that the butt plate can be easily pushed out or in of the buttstock housing while the button is pressed.

When the actuating element is closed, the two teeth come into engagement again and are then designed to be self-locking, i.e. H. The toothing solidifies automatically due to the acting recoil force, namely the closing torque.

The invention is not limited to the technical teaching of an actuating element which brings a toothing into or out of engagement by applying pressure.

Other actuating elements can also be used, such as. B. a pin which, by means of axial displacement, engages with its bolt-side end in an associated successive row of index bores on the outer circumference of the adjusting sleeve, in order to also enable an adjustable length of the butt plate, the damping device also being integrated into this butt cap. Self-locking, stepless wedge connections or eccentric clamping devices for the length adjustment between the two mutually movable and lockable sleeve parts are also possible.

According to a preferred feature of the invention, the damping device can be integrated into the adjusting device for adjusting the effective length of the buttstock in that the damping device is present in the area between the piston-shaped extension of the butt cap and the adjusting sleeve and the adjusting sleeve itself can then be adjusted in a guide sleeve fixed to the housing can be moved and fixed.

It is therefore a matter of the coaxial engagement of three interlocking elements, with the inner element, i.e. H. the piston rod connected to the butt cap or the piston shoulder forms the damping device in the direction of the length-adjustable adjustment sleeve, while the length-adjustable adjustment sleeve is held in a length-adjustable manner in a guide sleeve fixed to the housing.

This has the advantage that the adjustment sleeve for the length adjustment position contains the damping device and interacts with the piston attachment fixed to the butt cap. This means that the damping device is arranged in the adjustment sleeve and not in the buttstock housing, as is the case in the prior art.

This is a significant difference compared to the US 10,317,165 B2 , because the length adjustment of the buttstock is arranged at a completely different construction point in the buttstock than the damping device for the recoil absorption of the buttplate. This takes up a lot of space. If the butt plate is according to the mentioned Patent specification is set, the damping device must be set additionally and separately, which is not necessary in the present invention.

The advantage of the invention is that the damping device always moves automatically with the length-adjustable adjustment sleeve because it is arranged in the length-adjustable adjustment sleeve and this in turn is slidably mounted in a guide sleeve fixed to the housing.

It is particularly advantageous if the damping path limitation is arranged in the area between the piston rod and the adjusting sleeve, because the piston rod can be moved in the adjusting sleeve by the damping path and is supported against a recoil spring.

Therefore, the two parts need to be mounted in one another in a displaceable manner, which is preferably done with the help of a cylinder pin, which is arranged in a transverse bore in the piston shoulder of the butt plate and can be moved in an elongated hole pointing in the axial direction in the adjusting sleeve used for length adjustment.

This ensures a damped displacement of the two parts, with the cylindrical pin preferably being arranged in a transverse bore in the piston shoulder and being arranged in the adjusting sleeve in the said elongated hole so that it can be displaced in the axial longitudinal direction. This means that the damping force is always independent of the adjustment length of the adjustment sleeve and therefore independent of the shaft length of the buttstock.

A helical compression spring is preferably used to dampen the recoil force, but the invention is not limited to this. Any other force storage device can be used instead of a helical compression spring, such as: B. an elastomer spring, a disc spring, a leg spring or a hydraulic or pneumatic or a friction damper.

It is important that the adjustment of the damping force is not necessary depending on the adjustment length of the buttstock length; but this with the US 10,317,165 B2 the case is.

By integrating the damping device in the adjustment device in the buttstock housing in conjunction with a guide plate arranged in the buttstock housing, a sealed and dirt-protected system is created which is insensitive to the ingress of water or dirt.

In the prior art, the parts mentioned are open and freely accessible from the outside, which makes these parts sensitive to contamination or malfunction.

For design reasons, it is provided that the length of the buttplate of a long weapon can be adjusted and dampened butt plate preferably consists of two parts, namely a buttplate receptacle and the buttplate connected to the buttplate receptacle. This has the advantage that the butt plate resting directly on the shooter's shoulder can carry additional padding or is itself designed as an elastomeric body. However, the invention is not dependent on this two-part design; More than two parts can also form the assembled buttplate or it can also be provided that the buttplate receptacle is also formed - at least partially or completely - from an elastomeric body.

The subject matter of the present invention arises not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

All information and features disclosed in the documents, including the summary, in particular the spatial configuration shown in the drawings, could be claimed as essential to the invention if, individually or in combination, they are new compared to the prior art. The use of the terms “essential” or “according to the invention” or “Essential to the invention” is subjective and does not imply that the features named in this way necessarily have to be part of one or more patent claims.

The drawings generally show a weapon 1, which in a preferred exemplary embodiment is designed as a hunting or sporting weapon. The use of the damping and length adjustment device 25 according to the invention for the buttplates of hunting and sporting weapons is preferred because such weapons should ensure particular comfort when firing and protect the shooter's shoulder against recoil blows and at the same time ensure a particularly good stop of the weapon through the adjustment to ensure or enable the shooter's body size and ergonomics.

However, the invention is not limited to use in hunting and sporting weapons.

The weapon shown can also be provided in other weapon designs, as shown in the prior art publications mentioned. These are preferably semi-automatic weapons, or shotguns, or fully automatic weapons and similar weapons.

In general, the invention relates to shoulder-supported handguns, and the invention is based on the object of optimally adjusting a length-adjustable butt plate on such a long weapon to the shooter and at the same time ensuring that the damping effect is always maintained without any further adjustment effort.

For this purpose, the weapon 1 according to the preferred exemplary embodiment in the version as a hunting or sporting weapon in the drawings provides that a barrel 5 is arranged on a forend 3 and an additional telescopic sight 2 can also be attached, which the invention is not dependent on. The forend 3 is located in front of the trigger unit 4, in which a trigger 11 is arranged.

A butt plate 7, which is adjustable in length and dampened in the firing direction, is arranged in an adjustable manner in a weapon-proof buttstock housing 10, and the adjusting device is actuated by a hand-operated actuating element 8. An eyelet 9 for a sling swivel is arranged on the lower side of the buttstock housing. The trigger unit 4 has a pistol grip 12, to which the invention is not limited. Any trigger units and any holding devices can be used for such weapons. The only focus of the invention is that the shoulder-supported butt plate 7 is adjustable in its effective length and is dampened with respect to the recoil force acting during the firing of the shot.

This is how it shows Figure 1 generally the effective damping path 14 as the distance between the rear edge 15 on the buttstock housing 10 and the associated front edge 16 of the buttplate 7 in the minimum length setting, which always remains the same regardless of the setting length of the buttplate 7.

Furthermore, the comparison between the Figures 2 and 3 the possible adjustment play of the effective length of the buttstock 50. Off Figure 2 It can be seen that the buttstock 50 with its butt plate 7 is adjusted and locked backwards by a relatively large length adjustment range 13, while the Figure 3 The comparison shows that the butt plate 7 is set away from the rear edge 15 of the buttstock housing 10 by a smaller adjustment path 13a.

The effective length of the buttstock 50 can thus be individually adjusted to the shooter's body dimensions without tools.

To operate the length adjustment device, the actuating element 8 is preferably actuated with the fingers of one hand, during actuation the actuating element 8 against the force of an energy accumulator (preferably in the form of two mutually parallel push-off springs 38 see Fig. 8, 9 ) must be pressed in order to then pull the butt plate out of the buttstock housing 10 or push it into it with the other hand. The shift takes place in the direction of arrow 32 (see Figure 5 ). When the actuating element 8 is actuated again, the associated toothings 30, 34 engage one another again - preferably self-locking - and the selected extension length of the butt plate 7 is thus fixed and secured against unintentional displacement when the shot is fired.

According to Figure 3 The buttstock 50 can continue in the form of front side plates 46 into the system box of the weapon.

From the comparison of the Figures 4 and 5 further details of the invention emerge. In Figure 4 It is shown that with the minimum setting length of the butt plate 7, only the damping path 14 is present between the two lines 15 and 16. Line 15 is the rear edge of the buttstock housing 10, while line 16 denotes the front edge of the buttplate receptacle 55.

The Figure 5 shows the locked position of the adjusting device for adjusting the length of the butt plate, whereby it can be seen that the actuating element 8 is firmly connected to a pivotable locking element 18 is, which has on its upper side a rack-like counter-toothing 34 running in the longitudinal direction, which interacts with an external rack-like toothing 30, also directed in the axial direction, on the outer circumference of an adjusting sleeve 22.

After Figure 4 In the locked state, the toothing 30, 34 of the two interlocking parts is directed in such a way that when a recoil occurs in the recoil direction 51, the two interlocking toothings solidify or close themselves due to the closing torque.

The locking element 18 can be pivoted in a spring-loaded manner about a pivot bearing 27 fixed to the housing, which pivot bearing 27 is arranged in a fixed bearing 28, which is arranged in the buttstock housing 10.

The buttplate 7 is connected to the buttplate receptacle 55, in which the damping and adjustment device 25 is integrated, using fastening screws (not shown) which engage in associated screw holes 17.

The butt plate receptacle 55 with the damping and adjustment device 25 installed there preferably consists of a part made of uniform material (see Figure 12 ), on which a piston extension 21 directed in the axial direction is formed in the front part. However, the invention is not limited to this. It can also be provided in another embodiment that the piston shoulder 21 is attached to the butt cap receptacle 55 as a workpiece-separated part.

The piston shoulder 21 on the butt cap side corresponds to that Figures 4 to 6 and the basic sketch in Figure 15 slidably mounted in the adjusting sleeve 22 carrying the teeth and according to a preferred feature of the invention, the damping device is arranged between the end face 22a of the piston extension 21 and the associated end face of the adjusting sleeve 22. This results, for example, from Figure 10 , where it can be seen that the recoil spring 23 is supported with a rear end on a stop of reduced diameter on the end face of a longitudinal bore 49 arranged in the butt plate receptacle 55.

The other end of the recoil spring 23, which is preferably designed as a helical compression spring, is supported on the inner end face 22a of the adjusting sleeve 22. The damping device, consisting of the recoil spring 23, is thus arranged between the two mutually coaxial parts (piston shoulder 21 and adjusting sleeve 22).

Based on Figures 5 and 6 The adjustment process for adjusting the length of the butt plate 7 in relation to the buttstock housing 10 is explained below. This shows Figure 5 the closed and locked position of the damping and length adjustment device 25 and shows that the actuating element 8 with its slide 37 is held in the locking position by the force of the locking spring 36 and is spring-loaded in a receiving hole for the actuating element 8 in the buttstock housing 10. In the Figure 5 The locking position of the damping and length adjustment device 25 shown preferably uses a self-locking toothing, which means that the in Figure 6 counter toothing 34 shown in more detail on the locking element 18 is in self-locking engagement with the toothing 30 on the outside of the adjusting sleeve 22. This means that high recoil forces can be absorbed, which are transferred from the butt stock to the butt plate when a propellant charge is ignited, without causing an unintentional change in the setting length of the butt plate.

To change the effective length of the butt cap 7 in the area of the adjustment area 13a, for example, it is moved out of its locked position Figure 4 and 5 into an unlocked position Figure 6 pressed out of the buttstock housing 10 to the right in the direction of arrow 35. To do this, it is only necessary to actuate the slide 37 on the actuating element 8 in the direction of arrow 33 against the force of the locking spring 36 with the finger of one hand, whereby the locking part 18 moves under the force of the push-off springs 38 around the pivot bearing 27 into the in Figure 6 shown open position pivots and is held spring-loaded in this open position by means of the push-off springs 38. The nose 56 of the locking element 18 is spring-loaded against the stop surface 57 on the housing side. The slide 37 no longer needs to be actuated in this open position. The Damping and length adjustment device therefore remains in the spring-loaded open position.

This condition is in Fig. 6 shown. The counter toothing 34 of the locking element 18 is constantly and spring-loaded out of engagement with the toothing 30 on the adjusting sleeve 22, so that the buttplate 7 with the buttplate receptacle 55 can be easily pulled out or pushed in from the buttstock housing 10 - and without actuating further adjusting means. The adjusting sleeve 22 slides with the piston shoulder 21 in the interior of the buttstock-side guide sleeve 20 in the direction of arrow 32 to the right or left. When the shooter's desired extension or insertion length of the butt plate 7 from or in the buttstock housing 10 has been found, he will actuate the actuating element 8 again. In doing so, it presses the actuating element 8 against the force of the push-off springs 38 in the direction of arrow 33 into the receiving hole on the stock side. This causes the spring-loaded slide 37, which is held in the open position, to snap behind the stop edges 56, 57 arranged in the area of the receiving hole and fixes it. This is the locked position of the actuating element 8 according to Figure 5 reached.

The Figure 10 shows compared to Figure 4 and Figure 5 also that the adjustment sleeve 22 carrying the teeth 30 is slidably mounted in the guide sleeve 20 fixed to the housing.

10 fixed parts in the buttstock housing are shown schematically in Figure 10 Symbolically marked by a fixed point 44 to make it clear which part can be moved in which.

According to the schematic representation in Figure 15 is a specific damping path 14 (see Figure 1 ) between the two parts 21, 22 regardless of the setting length of the butt plate 7. To limit the damping path 14, a cylindrical pin 26 is provided, which is held in its position in an elongated hole 52 in the butt plate receptacle 55 by a retaining spring 24. The retaining spring 24 is supported on one side on a shoulder enlarged diameter in the longitudinal bore 49. The other spring end of the retaining spring 24 rests on the cylinder pin 26.

The damping path 14 is therefore determined by the displacement play of the cylindrical pin 26 in the axially aligned elongated hole 52 in the buttplate receptacle 55, which is always maintained regardless of the adjustment length of the displacement of the buttplate 7.

According to the schematically shown connection 53 in Figure 15 and the constructive representation in Figure 14 It can be seen that the cylinder pin 26 slidably connects the piston shoulder 21 to the adjusting sleeve 22 via the elongated hole connection. The retaining spring 24 serves to secure the cylinder pin 26 in its position so that it is protected from falling out of the elongated hole 52.

The comparison of the Figures 4 and 5 shows that the adjusting sleeve 22 is slidably mounted with a longitudinal guide 19 in the guide sleeve 20 fixed to the housing.

The Figure 4 also shows that in the mutually parallel and axially directed bores 58, 59 in the butt plate receptacle 55, further longitudinal guide elements - not shown in the drawing - can be arranged, which can interact with assigned longitudinal guides in the buttstock housing 10. Such longitudinal guide elements can be guide bolts which engage in associated recesses in the buttstock housing 10 and are guided there in an easily displaceable manner.

The fixed bearing 28 is provided with a fastening 29 in the buttstock housing 10 Figure 4 attached.

The Figure 5 shows the maximum possible setting length, namely the setting range 13a, while the Figure 6 shows that the setting length can be freely moved and fixed. In addition to the above description, it is also explained that the actuating element 8 is actuated in the direction of arrow 33 with a finger of one hand, whereby the slide 37, which is preloaded by a locking spring 36, can be actuated as a securing element for the actuating element 8.

The actuating element 8 with its locking element 18 molded onto it can then be moved in the direction of arrow 35 with the force of the two push-off springs 38 (see Figure 9 ) can be pivoted in the direction of arrow 35 in order to bring the counter toothing 34 on the locking element 18 out of engagement with the sleeve-side toothing 30 of the adjusting sleeve 22. This is done with the force of the two mutually parallel push-off springs 38 (see Figure 9 ), whereby the push-off springs 38 are preferably designed as leg springs.

One end of the leg spring is supported on the fixed bearing 28, while the other end of the leg spring is supported on a stop pin 39, which carries out the spring-loaded pivoting of the locking element 18.

When adjusting the length, there is automatically a free space 31 between the inner end of the guide sleeve 20 fixed to the housing and the end face 22a of the adjusting sleeve 22. The interaction of the teeth is also in Figure 10 presented with important parts omitted.

The damping and adjustment device 25 according to the invention is in perspective Figure 12 shown, where it can be seen that in the interior of the guide sleeve 20, which is fixedly arranged in the buttstock housing 10, the displaceable adjusting sleeve 22 can be moved in the directions of the arrows 32, which carries the previously mentioned teeth 30 on its underside.

In contrast, the locking element 18 carries the counter-toothing 34, so that the two parts are connected to one another in an adjustable and lockable manner and the counter-toothing 34 always presses onto the nose 56 on the stop surface 57 of the buttstock housing 10 under the action of the two parallel push-off springs 38 and thus also the Secure engagement with the sleeve-side teeth 30.

The Figure 12 shows that the butt plate 7 is spaced from a guide plate 40 via an adjustment range 13a and the guide plate 40 is part of the buttstock housing 10.

Thus, the damping and adjustment device 25 according to the invention consists of the butt plate 7 itself and the parts in the buttstock housing 10, in particular the guide plate 40, which is fixed in the buttstock housing 10 with the aid of threaded inserts 41.

The body that forms the piston shoulder 21 is referred to as a butt cap receptacle 55, to which the butt cap 7 is attached using screws in the screw holes 17.
Thus, the two parts 7, 55 are firmly connected to one another and their overall distance from the buttstock housing 10 is adjustable and dampened against recoil. From the Figures 5 and 6 It can be seen that the butt cap receptacle 55 forms the piston shoulder 21 in the axial direction forward, which is damped and displaceably arranged in the interior of the adjusting sleeve 22 via the front recoil spring 23. The adjusting sleeve 22 is guided in a length-adjustable and lockable manner with the longitudinal guide 19 in the guide sleeve 20, which is fixedly arranged on the buttstock housing side.

In the guide plate 40, guide sleeves 42 directed in the axial direction are formed, which are part of the butt cap receptacle 55. The guide sleeves 42 serve to prevent rotation of the butt plate receptacle 55 when engaging in the buttstock housing 10 (see Figure 6 ).
This means that the buttplate receptacle 55, together with the buttplate attached to it, is secured against rotation, but can be moved and fixed in the axial direction, and is guided in the buttstock housing 10 in a spring-loaded, dampened manner.

The guide plate 40 has according to Figure 12 a circumferential contour 43, which forms a collar projecting in the axial direction, which serves to guide the displacement of the butt plate receptacle 55.

As already stated previously, the parts fixed to the housing, which are connected to the buttstock housing 10 and the buttstock 50, are symbolically designated with fixed points 44 in order to identify their connection to the buttstock housing 10.

In Figure 12 one spring leg 47 of one of the impression springs 38 is still visible, which is supported by a spring on the stop pin 39, which is connected to the locking element 18. The opposite spring leg rests on the fixed bearing 28.

From the comparison between Figure 11 and the Figures 14 and 15 It can be seen that the mutual damped displacement between the piston shoulder 21 of the butt plate receptacle 55 and the adjusting sleeve takes place via the named cylinder pin 26, which is held displaceably and spring-loaded in an elongated hole 52 in the area of the adjusting sleeve. The Figure 14 shows that the cylinder pin 26 connects the piston shoulder 21 with the adjusting sleeve 22, which symbolically in Figure 15 is given as schematic connection 53.

The Figure 9 also shows that the other spring legs of the push-off springs 38 are supported on assigned stop surfaces 48 on the fixed bearing 28.

Overall, the described damping and adjustment device 25 discloses a highly integrated device that is protected against contamination and incorrect operation and which provides and ensures damping in any setting position of the butt plate 7.

Of course, the present invention is not limited to a recoil spring 23 designed as a helical compression spring for the damping device; Other energy storage devices, such as elastomeric springs, leg, spiral or disc springs, can also be used. Additional damping devices can be assigned to the energy storage device, such as a friction damper or a hydraulic or pneumatic damper.
