Length-adjustable stock cap with integrated recoil damping for a firearm, especially a hunting or sporting firearm.

Description

[0001] The invention relates to a length-adjustable butt plate with integrated recoil damping for shoulder-held handguns in the form of long guns, in particular in the form of hunting and sporting weapons.

[0002] A butt plate with integrated recoil damping, but without adjustable effective length, is known, for example, from US Patent 10,317,165 B2. The butt plate shown there is fitted with a fluid damper in the buttstock. The fluid damper's cylinder housing rests in the buttstock, and its piston rod is supported by the butt plate, thus damping the butt plate. A disadvantage of this arrangement, however, is that adjustable buttstock length is not possible. Since the support for the damping piston rod against the butt plate always remains constant, adjusting the butt plate's length in the buttstock is not possible. Only the damping force can be adjusted.

[0003] US patent 7 762 018 B1 discloses an arrangement in which the length of the buttstock is adjustable and fixed. However, this arrangement does not feature butt plate damping.

[0004] US 10 578 394 B2 is a type of butt plate damping system that also uses a fluid damper, but in which the length of the buttstock can be adjusted by inserting adapter plates, resulting in a cumbersome and very difficult-to-operate adjustment of the buttstock length.

[0005] US 7 762 018 B1 is known to have a buttstock length adjustable via detent mechanism, but it lacks damping.

[0006] The invention, based on US 10,317,165 B2, is based on the objective of further developing the butt plate on the buttstock of a firearm, in particular a hunting or sporting firearm, in such a way that the butt plate is dampened while simultaneously allowing adjustment of the buttstock length. Another relevant prior art document is US 2004 / 031182 A1.

[0007] To solve the problem posed, the invention is characterized by the technical teaching of claim 1.

[0008] According to the invention, the damping unit is integrated into the length adjustment unit for adjusting the butt plate.

[0009] This offers the advantage of a very compact, reliable and contamination-protected design, with the elements of a damping unit and a length adjustment device arranged coaxially nested within a single assembly in the buttstock housing.

[0010] The butt plate is guided in a damped manner within the buttstock housing, allowing longitudinal movement and locking.

[0011] This ensures that the damping of the butt plate is integrated into the length adjustment device in the buttstock housing, and that the damping unit always participates when the length is changed in the length adjustment device, so that the damping unit provides consistent damping regardless of the length adjustment device.

[0012] Mastering this combined task presented significant challenges, as it was necessary to integrate the damping and length adjustment device into the buttstock housing in such a way that the butt plate is both slidably and lockably mounted in the buttstock housing, and that the damping device is connected to this length adjustment device in such a way that the damping of the butt plate is always maintained regardless of the length adjustment.

[0013] It is preferred that an axial projection of the butt plate (more precisely: the butt plate receptacle connected to the butt plate) is designed as an axial cylindrical piston projection of reduced diameter pointing in the direction of fire, which is coaxially displaceable by the length of the damping play in an adjusting sleeve on the butt plate side with a first larger diameter, wherein the adjusting sleeve is coaxially displaceable and fixed in the length of the adjusting play in a guide sleeve on the butt plate side with a second larger diameter.

[0014] 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.

[0015] When the coaxially interlocking sleeve parts of the damping device and length adjustment device are described as "cylindrical," this is to be understood merely as a preferred embodiment. The aforementioned coaxially interlocking parts can also have other cross-sectional shapes instead of a cylindrical one, such as oval, triangular, rectangular, square, or rhomboid cross-sectional shapes.

[0016] This implies 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 end of the butt plate (more precisely: the butt plate receptacle) is supported by a force storage element located on the front end face against the inner end face of the butt plate-side adjustment sleeve, which in turn is displaceably mounted in a fixed outer guide sleeve. This guide sleeve is fixed in the buttstock housing and forms the bearing unit for the aforementioned two movable, interlocking sleeve parts.

[0017] This offers the advantage that, for the first time, a combination of two coaxially interlocking sleeves on the buttstock side is realized, between which the damping device acts, while the outer of the two sleeves is length-adjustable in a guide sleeve on the buttstock housing side.

[0018] A particular advantage is that the damping and length adjustment device is arranged in the central and – preferably – centric guide element – ​​the piston extension – for the longitudinal guidance of the butt plate within the buttstock. This results in a space-saving design and, on the other hand, excellent properties for the sliding guidance of the butt plate within the buttstock. This ensures smooth and jam-free sliding of the butt plate within the buttstock. The adjusting sleeve serving for longitudinal guidance, in conjunction with the piston extension, is preferably arranged in the butt plate receptacle and engages in a corresponding axial longitudinal bore in the buttstock, where it is slidably and lockably guided.

[0019] In another embodiment of the invention, however, a kinematic reversal of the previously described arrangement may be provided in such a way that the central piston extension with the associated adjusting sleeve is arranged on the buttstock and engages in a central bore in the buttplate receptacle, where it is slidably and lockably guided. The damping and length adjustment device is then also arranged in the buttstock-side piston extension and fulfills all the functions described in connection with the arrangement of the piston extension in the buttplate receptacle.

[0020] It may also be provided that, as a guide device for the longitudinal guidance of the butt plate receiver in the buttstock, not only the piston extension - which accommodates the damping and length adjustment device - is present, but also further longitudinal guide elements or damping elements acting parallel to the piston extension are arranged between the butt plate receiver and the buttstock.

[0021] It is also preferred if the length adjustment is implemented as a self-locking toothed mechanism. A toothed section is arranged on the outer circumference of the butt plate-side adjustment sleeve, which engages with a mating toothed section on a locking element fixed to the housing (i.e., located on the buttstock-housing side). The locking element is spring-loaded and pivotally mounted on a housing-mounted pivot bearing, and its mating toothed section engages with the toothed section on the outer circumference of the butt plate-side adjustment sleeve. It is preferred if the recoil force acting on the butt plate during firing exerts a closing torque on the interlocking toothed sections, thus forming an additional safety element to prevent unintentional displacement of the butt plate, which is fixed in length.

[0022] It is particularly preferred if the length adjustment with the said counter-toothing can be triggered by a hand-operated actuating element, which is designed as a pivot button or push button and is able, with a suitable spring arrangement, to disengage the counter-toothing of the actuating element from the toothing on the outer circumference of the adjusting sleeve or - conversely - to bring it into engagement under spring pressure.

[0023] It is preferred that the actuating button be arranged on the lower surface of the buttstock and – as shown – be designed as a pivot button or a push button that is lockable in the rest position to prevent unintentional actuation. The advantage of this arrangement on the underside of the buttstock is that the length adjustment is particularly easy to operate, because when the actuating element is pressed, the counter-teeth of a locking element rigidly connected to the actuating element are disengaged from the teeth of the adjustment sleeve in the buttstock housing. This allows the butt plate to be easily slid in or out of the buttstock housing while the actuating button is pressed.

[0024] When the actuating element is closed, the two teeth engage again and are then self-locking, i.e. the teeth tighten automatically due to the acting recoil force, namely the closing torque.

[0025] According to the invention, when the length adjustment is actuated, a toothed gear is brought into or out of engagement with a counter-toothed gear.

[0026] Other actuating elements, such as a pin whose bolt-side end engages with axial displacement into a corresponding series of consecutive index bores on the outer circumference of the adjusting sleeve, thus also enabling an adjustable length of the butt cap, with the damping device being simultaneously integrated into this butt cap. Likewise, self-locking stepless wedge connections or eccentric clamping devices are possible for length adjustment between the two mutually displaceable and lockable sleeve parts.

[0027] According to a preferred feature of the invention, the integration of the damping device into the adjustment device for adjusting the effective length of the buttstock is preferably achieved by the damping device being located in the area between the piston-shaped extension of the buttstock cap and the adjustment sleeve, and by the adjustment sleeve itself being adjustable, displaceable and lockable in a housing-fixed guide sleeve.

[0028] This involves the coaxial engagement of three interlocking elements, wherein the inner element, i.e., the piston rod or piston extension connected to the butt plate, forms the damping device in the direction of the length-adjustable adjusting sleeve, while the length-adjustable adjusting sleeve is held length-adjustable within a housing-fixed guide sleeve. This offers the advantage that the adjusting sleeve for length adjustment contains the damping device and interacts with the butt plate-fixed piston extension. This means that the damping device is located in the adjusting sleeve and not in the buttstock housing, as is the case in the prior art.

[0029] This is a significant difference compared to US 10,317,165 B2, because there the length adjustment of the buttstock is located at a completely different point in the buttstock than, for example, the recoil damping device for the butt plate. This requires a considerable amount of installation space. When the butt plate is adjusted according to the aforementioned patent, the recoil damping device must also be adjusted separately, which is not necessary with the present invention.

[0030] The advantage of the invention is that the damping device always moves automatically with the length-adjustable adjusting sleeve, because it is arranged in the length-adjustable adjusting sleeve and the latter is slidably mounted in a housing-fixed guide sleeve.

[0031] It is particularly advantageous if the damping travel limiter is located in the area between the piston rod and the adjusting sleeve, because the piston rod can be moved around the damping travel in the adjusting sleeve and is supported against a recoil spring.

[0032] Therefore, a sliding mounting of the two parts into each other is required, which is preferably done with the help of a cylindrical pin that is arranged in a transverse bore in the piston base of the shaft cap and is slidable in an axially pointing elongated hole in the adjusting sleeve used for length adjustment.

[0033] This ensures a damped displacement of the two parts, with the cylindrical pin preferably arranged in a transverse bore in the piston base and being axially displaceable in the longitudinal direction within the aforementioned elongated hole, thus dampening its movement in the adjusting sleeve. This means the damping force is always independent of the adjustment length of the adjusting sleeve and therefore independent of the buttstock length.

[0034] A helical compression spring is preferably used to dampen the recoil force, although the invention is not limited to this. Any other energy storage device can be used instead of a helical compression spring, such as an elastomer spring, a disc spring, a torsion spring, or a hydraulic, pneumatic, or friction damper.

[0035] It is important to note that readjusting the damping force depending on the adjustment length of the buttstock is not necessary; however, this is the case with the US 10,317,165 B2.

[0036] By integrating the damping device into the adjustment device in the buttstock housing in conjunction with a guide plate arranged in the buttstock housing, a sealed and contamination-protected system is created which is insensitive to the ingress of water or dirt.

[0037] In the current state of the art, the aforementioned parts are open and freely accessible from the outside, which makes these parts susceptible to contamination or malfunction.

[0038] For design reasons, the adjustable and cushioned buttplate of a long gun preferably consists of two parts: a buttplate receptacle and the buttplate connected to the receptacle. This offers the advantage that the buttplate, which rests directly on the shooter's shoulder, can have additional padding or be itself made of an elastomeric material. However, the invention is not limited to this two-part design; the buttplate can also be composed of more than two parts, or the buttplate receptacle can be formed—at least partially or completely—of an elastomeric material.

[0039] The subject matter of the present invention is not only derived from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

[0040] All information and features disclosed in the documents, including the abstract, and in particular the spatial configuration shown in the drawings, could be claimed as essential to the invention, insofar as they are novel individually or in combination compared to the prior art. The use of the terms "essential," "inventive," or "essential to the invention" is subjective and does not imply that the features so designated must necessarily be part of one or more patent claims.

[0041] The invention is explained in more detail below with reference to drawings illustrating only one embodiment. Further essential features and advantages of the invention will become apparent from the drawings and their description.

[0043] The drawings generally depict a weapon 1, which in a preferred embodiment is designed as a hunting or sporting weapon. The application of the damping and length adjustment device 25 according to the invention for the butt plates of hunting and sporting weapons is preferred, as such weapons are intended to ensure particular comfort during firing and to protect the shooter's shoulder against recoil, while ensuring or enabling a particularly good shooting position by adapting to the shooter's height and ergonomics.

[0044] However, the invention is not limited to use in hunting and sporting weapons.

[0045] The depicted weapon can also be provided in other weapon configurations, as described in the aforementioned publications according to the prior art. These are preferably semi-automatic weapons, shotguns, fully automatic weapons, and similar weapons.

[0046] In general, the invention relates to shoulder-fired handguns, and the object of the invention is to optimally adjust a length-adjustable butt plate on such a long gun to the shooter and at the same time to ensure that the damping effect is always maintained without further adjustment effort.

[0047] According to the preferred embodiment, the weapon 1, in its configuration as a hunting or sporting weapon as shown in the drawings, has a barrel 5 attached to a fore-end 3 and a telescopic sight 2 can also be mounted on it, although this is not a requirement of the invention. The fore-end 3 is located in front of the trigger unit 4, in which a trigger 11 is arranged.

[0048] A length-adjustable butt plate 7, dampened in the direction of fire, is adjustably arranged in a weapon-mounted buttstock housing 10, and the adjustment mechanism is actuated by a hand-operated actuating element 8. A sling swivel stud 9 is arranged on the underside of the buttstock housing. The trigger unit 4 has a pistol grip 12, but the invention is not limited to this. Any trigger unit and any holding device for such weapons can be used. The primary focus of the invention is simply that the shoulder-supported butt plate 7 is adjustable in its effective length and dampened with respect to the recoil force acting during firing.

[0049] This shows Figure 1generally 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 butt plate 7 in the minimum length setting, which always remains the same regardless of the setting length of the butt plate 7.

[0050] Furthermore, the comparison between the Figures 2 and 3 the possible adjustment range of the effective length of the buttstock 50. From Figure 2 It is evident that the buttstock 50 with its butt plate 7 is adjusted and locked to the rear over a relatively large length adjustment range 13, while the Figure 3 In comparison, it shows that the butt plate 7 is fixed a shorter distance 13a from the rear edge 15 of the buttstock housing 10.

[0051] Thus, the effective length of the buttstock can be individually adjusted to the shooter's body dimensions without tools.

[0052] To actuate the length adjustment device, the actuating element 8 is preferably operated with the fingers of one hand, wherein during actuation the actuating element 8 is against the force of a force storage device (preferably in the form of two parallel push-off springs 38 see Fig. 8, 9 ) must be pressed in order to then pull the butt plate out of or push it into the buttstock housing 10 with the other hand. The movement is in the direction of arrow 32 (see Figure 5 ). When the actuating element 8 is actuated again, the corresponding toothings 30, 34 engage again - preferably self-locking - and the selected extension length of the butt plate 7 is thus fixed and secured against unintentional displacement when firing.

[0053] According to Figure 3 The buttstock 50 can continue into the system box of the weapon in the form of front side plates 46.

[0054] From the comparison of Figures 4 and 5 Further details of the invention emerge in Figure 4 It is shown that with the minimum adjustment length of the butt plate 7, only the damping path 14 between the two lines 15 and 16 remains. Line 15 is the rear edge of the buttstock housing 10, while line 16 designates the front edge of the butt plate receptacle 55.

[0055] The Figure 5 Figure 1 shows the locked position of the adjusting device for length adjustment of the shaft cap, showing that the actuating element 8 is firmly connected to a pivotable locking element 18, which has a longitudinally extending rack-like counter toothing 34 on its upper side, which interacts with an external, also axially directed rack-like toothing 30 on the outer circumference of an adjusting sleeve 22.

[0056] After Figure 4The toothing 30, 34 of the two interlocking parts in the locked state is oriented such that, when a recoil occurs in the recoil direction 51, the two interlocking toothings tighten or close themselves due to the closing torque.

[0057] The locking element 18 is spring-loaded and pivotable about a housing-fixed pivot bearing 27, which pivot bearing 27 is arranged in a fixed bearing 28, which is arranged in the buttstock housing 10.

[0058] The butt plate 7 is connected to the butt plate receptacle 55, in which the damping and adjustment device 25 is integrated, by means of fastening screws (not shown) which engage in associated screw holes 17.

[0059] The butt plate receptacle 55 with the damping and adjustment device 25 installed therein preferably consists of a single part made of a single material (see Figure 12), to which an axially directed piston extension 21 is integrally formed in the front part. However, the invention is not limited to this. In another embodiment, the piston extension 21 can also be attached to the stock cap receptacle 55 as a workpiece-separated part.

[0060] The piston end 21 on the stock cap side is designed according to the Figures 4 to 6 and the schematic diagram in Figure 15 The damping device is slidably mounted in the adjusting sleeve 22 which carries the toothing, and according to a preferred feature of the invention, it is arranged between the end face 22a of the piston extension 21 and the associated end face of the adjusting sleeve 22. This is evident, for example, from Figure 10 , where it can be seen that the recoil spring 23 is supported at a rear end on a stop of reduced diameter on the front face of a longitudinal bore 49 arranged in the butt plate receptacle 55.

[0061] The other end of the recoil spring 23, preferably designed as a helical compression spring, is supported against the inner end face 22a of the adjusting sleeve 22. Thus, the damping device, consisting of the recoil spring 23, is arranged between the two coaxial parts (piston extension 21 and adjusting sleeve 22).

[0062] Based on the Figures 5 and 6 The following explains the adjustment procedure for setting the length of the butt plate 7 in relation to the buttstock housing 10. The Figure 5 The closed and locked position of the damping and length adjustment device 25 is shown, indicating that the actuating element 8 with its slide 37 is held in the locked position by the force of the locking spring 36 and is spring-loaded in a receiving bore for the actuating element 8 in the buttstock housing 10. The in Figure 5The depicted locking position of the damping and length adjustment device 25 preferably uses a self-locking toothing, which means that the Figure 6 The counter-toothing 34 on the locking element 18, shown in more detail, is in self-locking engagement with the toothing 30 on the outside of the adjusting sleeve 22. This allows even high recoil forces, which are transmitted from the buttstock to the butt plate during the ignition of a propellant charge, to be absorbed without unintentionally changing the adjustment length of the butt plate.

[0063] To change the effective length of the butt plate 7 in the area of ​​the adjustment range 13a, it is, for example, moved from its locked position into Figure 4 and 5 into an unlocked position Figure 6The locking element 18 is pushed out of the buttstock housing 10 to the right in the direction of arrow 35. This is achieved simply by actuating 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, under the force of the ejector springs 38, is pushed around the pivot bearing 27 into the Figure 6 The open position shown pivots and is held in this open position by means of the springs 38. The nose 56 of the locking element 18 then rests against the housing-side stop surface 57 under spring pressure. The slide 37 therefore no longer needs to be actuated in this open position. The damping and length adjustment device thus remains in the spring-loaded open position.

[0064] This condition is in Fig. 6The counter-toothing 34 of the locking element 18 is permanently and spring-loaded disengaged from the toothing 30 on the adjusting sleeve 22, so that the butt plate 7 with the butt plate receptacle 55 can be easily pulled out of or pushed into the buttstock housing 10 without the need for any further adjustments. The adjusting sleeve 22 with the piston extension 21 slides inside the buttstock-side guide sleeve 20 in the direction of arrow 32 to the right or left. Once the desired extension or insertion length of the butt plate 7 has been found, the shooter will actuate the actuating element 8 again. This pushes the actuating element 8 against the force of the release springs 38 in the direction of arrow 33 into the buttstock-side receiving bore.This causes the spring-loaded slide 37, held in the open position, to snap behind the stop edges 56, 57 located in the area of ​​the receiving bore and lock it in place. This establishes the locked position of the actuating element 8 as shown. Figure 5 reached.

[0065] The Figure 10 shows in comparison to Figure 4 and Figure 5 also that the adjusting sleeve 22, which carries the toothing 30, is slidably mounted in the housing-fixed guide sleeve 20.

[0066] The 10 fixed parts in the buttstock housing are schematically represented in Figure 10 symbolically marked by a fixed point 44 to indicate which part can be moved within which.

[0067] According to the schematic representation in Figure 15 is a specific damping path 14 (see Figure 1A gap exists between the two parts 21, 22, independent of the adjustment length of the butt plate 7. To limit the damping travel 14, a cylindrical pin 26 is provided, which is held in its position in a slot 52 in the butt plate receptacle 55 by a retaining spring 24, allowing it to slide within this slot. The retaining spring 24 is supported at one end by a shoulder of increased diameter in the longitudinal bore 49. The other end of the retaining spring 24 rests against the cylindrical pin 26.

[0068] The damping path 14 is therefore determined by the displacement play of the cylindrical pin 26 in the axially oriented elongated hole 52 in the stock cap receptacle 55, which is always maintained regardless of the adjustment length of the displacement of the stock cap 7.

[0069] According to the schematically represented connection 53 in Figure 15 and the constructive presentation in Figure 14It can be seen that the cylindrical pin 26 connects the piston extension 21 to the adjusting sleeve 22 via the elongated hole connection in a slidable manner. The retaining spring 24 serves to secure the cylindrical pin 26 in its position, preventing it from falling out of the elongated hole 52.

[0070] The comparison of Figures 4 and 5 shows that the adjusting sleeve 22 is slidably mounted with a longitudinal guide 19 in the housing-fixed guide sleeve 20.

[0071] The Figure 4 This also shows that further longitudinal guide elements – not shown in the drawing – can be arranged in the mutually parallel and axially directed bores 58, 59 in the butt plate receptacle 55, which can interact with associated longitudinal guides in the buttstock housing 10. Such longitudinal guide elements can be guide pins that engage in associated recesses in the buttstock housing 10 and are guided there so as to be easily slidable.

[0072] The fixed bearing 28 is connected to a fastening 29 in the buttstock housing 10 according to Figure 4 attached.

[0073] The Figure 5 shows the maximum possible setting length, namely setting range 13a, while the Figure 6 This shows that the adjustment length is freely adjustable and fixed. In addition to the description above, it is further explained that the actuating element 8 is actuated in the direction of arrow 33 with a finger of one hand, thereby enabling the slide 37, pre-tensioned by a locking spring 36, to actuate as a locking element for the actuating element 8.

[0074] The actuating element 8 with its integrally formed locking element 18 can then be moved in the direction of arrow 35 by the force of the two push-off springs 38 (see Figure 9) are pivoted in the direction of arrow 35 in order to disengage the mating toothing 34 on the locking element 18 from the sleeve-side toothing 30 of the adjusting sleeve 22. This is achieved by the force of the two parallel ejector springs 38 (see Figure 9 ), wherein the push-off springs 38 are preferably designed as torsion springs.

[0075] One end of the torsion spring is supported on the fixed bearing 28, while the other end of the torsion spring is supported on a stop pin 39, which performs the spring-loaded pivoting of the locking element 18.

[0076] During length adjustment, a clearance 31 automatically results between the inner end of the housing-fixed guide sleeve 20 and the end face 22a of the adjusting sleeve 22. The interaction of the gear teeth is also in Figure 10 Presented with important parts omitted.

[0077] The damping and adjustment device 25 according to the invention is shown in perspective in Figure 12 shown where it can be seen that inside the guide sleeve 20 which is fixedly arranged in the buttstock housing 10, the sliding adjustment sleeve 22 is movable in the directions of the arrows 32, which has the aforementioned toothing 30 on its underside.

[0078] In contrast, the locking element 18 carries the counter-toothing 34, so that the two parts are adjustable and lockable together and the counter-toothing 34 always presses against the nose 56 onto the stop surface 57 of the buttstock housing 10 under the action of the two parallel pressure springs 38 and thus also secures the engagement with the socket-side toothing 30.

[0079] The Figure 12 shows that the butt plate 7 is spaced from a guide plate 40 over an adjustment range 13a and that the guide plate 40 is part of the buttstock housing 10.

[0080] Thus, the damping and adjusting device 25 according to the invention consists of the butt cap 7 itself and the parts in the buttstock housing 10, in particular the guide plate 40, which is fixed in the buttstock housing 10 by means of threaded inserts 41.

[0081] The body forming the piston attachment 21 is referred to as the butt cap receptacle 55, to which the butt cap 7 is attached by means of screws in the screw holes 17.

[0082] Thus, the two parts 7 and 55 are firmly connected to each other and their distance to the buttstock housing 10 is adjustable and they are dampened against recoil. From the Figures 5 and 6It can be seen that the butt plate receptacle 55 forms the piston extension 21 in the axial direction forward, which is dampened by the recoil spring 23 on the front and is slidably arranged inside the adjusting sleeve 22. The adjusting sleeve 22 is guided length-adjustable and lockable by the longitudinal guide 19 in the fixed guide sleeve 20 on the buttstock housing side.

[0083] The guide plate 40 has axially oriented guide sleeves 42 molded into it, which are part of the butt plate receptacle 55. The guide sleeves 42 serve to prevent the butt plate receptacle 55 from rotating when engaging the buttstock housing 10 (see Figure 6 ).

[0084] This secures the butt plate receptacle 55 together with the butt plate attached to it against rotation, but allows it to be moved and fixed in the axial direction, and guides it in the buttstock housing 10 with spring-loaded damping.

[0085] 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.

[0086] As previously stated, the housing-fixed parts connected to the buttstock housing 10 and the buttstock 50 are symbolically designated by fixed points 44 to indicate their connection to the buttstock housing 10.

[0087] In Figure 12 One spring leg 47 of one of the pressure springs 38 is still visible, which is spring-loaded and supported against the stop pin 39, which is connected to the locking element 18. The opposite spring leg rests against the fixed bearing 28.

[0088] From the comparison between Figure 11 and the Figures 14 and 15It can be seen that the mutual damped displacement between the piston extension 21 of the stock cap receptacle 55 and the adjusting sleeve is effected via the aforementioned cylindrical pin 26, which is slidably held in a slot 52 in the area of ​​the adjusting sleeve and is spring-loaded. Figure 14 shows that the cylindrical pin 26 connects the piston extension 21 with the adjusting sleeve 22, which is symbolically represented in Figure 15 is indicated as schematic connection 53.

[0089] The Figure 9 This also shows that the other spring legs of the push-off springs 38 are supported on associated stop surfaces 48 on the fixed bearing 28.

[0090] Overall, the described damping and adjustment device 25 discloses a highly integrated device, protected against contamination and incorrect operation, which provides and ensures damping in any desired position of the butt plate 7.

[0091] 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, torsion springs, spiral springs or disc springs, can also be used.
