Abstract

Hunting or sporting firearm with an approximately symmetrical, roughly U-shaped profiled cheekpiece (3) arranged on a buttstock (5) of the firearm, the outer surface of which is suitable as a cheek rest (39) for the shooter's face, wherein a profile is arranged on the inner sides of the U-shaped legs of the cheekpiece which can engage with a complementary profile on the side surfaces of the buttstock (5), wherein the cheekpiece (3) can be slid onto the buttstock (5) and locked in the use position on the buttstock (5).

Description

[0001] The present invention relates to a hunting or sporting firearm according to the preamble of claim 1. A cheekpiece of the type mentioned at the outset is known, for example, from EP 4 180 758 A1, which is registered to the same applicant. The cheekpiece shown there is not symmetrical, i.e., it is designed differently on one side than on the other, which is associated with the disadvantage of more difficult handling.

[0002] The familiar cheekpiece is attached to the buttstock of a hunting or sporting rifle from above. The height of the cheekpiece relative to the stock can be adjusted by its various mounting positions. This allows for optimal alignment of the sight line for the shooter, as the height-adjustable cheekpiece can be tailored to the shooter's cheek area.

[0003] A disadvantage of the well-known cheekpiece according to EP 4 180 758 A1 is that it is asymmetrical and therefore unsuitable for left- and right-handed shooters. The fact that this cheekpiece can be attached to the stock of a hunting or sporting rifle makes it difficult to handle, as very high locking forces must be overcome to ensure a secure fit of the cheekpiece on the buttstock.

[0004] The patent EP 4 246 082 A1, also originating from the same applicant, reveals the same attachable cheek rest. With this version, adjusting the cheek rest's height is somewhat more difficult, as the notches are not visible and this tricky assembly requires a certain amount of feel from the user.

[0005] The subject matter of WO2023 / 028374A2 discloses a substantially symmetrical cheekpiece that can also be attached vertically to the stock of a hunting or sporting rifle. While it would be suitable for both left- and right-handed shooters, it has the disadvantage that the springs used to hold the cheekpiece in place must be quite strong to prevent unwanted play. Therefore, removing and attaching the cheekpiece to the buttstock requires considerable force.

[0006] The same cheek rest is also the subject of US patent application US2023 / 0068530A1. However, this design has the disadvantage that height adjustment is not possible, because... Fig. 9The aforementioned printed document shows that the lockable T-nut 16 can be locked into a non-adjustable longitudinal groove on the stock of the weapon, so that no height adjustment is possible.

[0007] The invention is therefore based on the objective of further developing a cheekpiece based on the subject matter of US2023 / 0068530A1 in such a way that it can be applied to the stock of a weapon with less effort and with a secure hold, and that its height is also adjustable, while retaining the advantage of left- or right-handed operation.

[0008] To solve the problem posed, the invention is characterized by the technical teaching of independent claim 1.

[0009] The invention relates to a hunting or sporting firearm with an approximately symmetrical, roughly U-shaped cheekpiece mounted on the buttstock. The outer surface of this cheekpiece is designed to rest against the shooter's face. A profile is arranged on the inner sides of the cheekpiece's U-shaped section, which engages with a complementary profile on the buttstock's side surfaces. The term "approximately symmetrical, roughly U-shaped profile" indicates that the cheekpiece should be usable by both left- and right-handed shooters without any loss of functionality or the need to reposition it. This means that minor deviations in the symmetrical side walls of the U-profile are possible and permissible, provided they do not impair its usability.

[0010] It is preferred that the cheek piece can be slid onto the buttstock from the rear part of the stock of the hunting or sporting firearm – relative to the weapon's operating position – preferably in a horizontal direction, and can be locked in a height-adjustable position in the direction of movement. Instead of a horizontal sliding direction, a sliding direction inclined at an angle to the horizontal is also possible.

[0011] According to a preferred feature of the technical teaching of claim 1, it is provided that the cheek piece can be slid onto the buttstock from the rear in the direction of fire of the weapon and can be locked onto the buttstock in the position of use.

[0012] In another version, it may be provided that the cheek piece can be slid onto the buttstock in the opposite direction of fire and locked in place.

[0013] According to a preferred feature of the invention, the adjustable cheek piece is height-adjustable. Sliding it from the rear of the buttstock forward towards the muzzle of the weapon offers the advantage of allowing for different cheek piece heights on the buttstock. To adapt the cheek piece to the shooter's face, the desired height above the buttstock can be selected before mounting it. The cheek piece is then slid onto the buttstock at the desired height. It is therefore height-adjustable and lockable on the buttstock of a hunting or sporting rifle.

[0014] These features of a symmetrical cheek piece, which is height-adjustable and lockable in its longitudinal displacement, cannot be found in any of the aforementioned printed materials.

[0015] The advantage of the measure according to the invention is that only a small sliding force is necessary to slide the cheek piece onto its mounting location on the buttstock, which is a significant advantage over the previously known cheek pieces that can be snapped on from above, because such cheek pieces can only be snapped onto the associated locking elements on the buttstock with a large locking or snapping force.

[0016] A further advantage of the invention lies in the fact that the cheekpiece can be attached on both the right and left side, because the corresponding retaining grooves on the buttstock of the hunting and sporting rifle are aligned with each other on both sides, thus also allowing the advantages of a symmetrical cheekpiece to be realized. This means that such a cheekpiece can also be used by left- or right-handed shooters without any adjustment effort or the need to replace the cheekpiece when switching from left- to right-handed shooting.

[0017] The cheek piece preferably has a U-profile and, due to its U-shape, acts like a saddle, which has the advantage that the cheek piece forms an upper inner cavity on the buttstock, into which, for example, the entire bolt of the weapon can be retracted during the cycling process, thus shortening the overall usable length of the weapon because the cheek piece covers the movement of the bolt on the buttstock and shields it from the shooter's face.

[0018] Thus, due to its hollow profile, the cheek piece forms a receiving space for a breech that can be inserted into it, something previously unknown in weapons technology.

[0019] The generic US2023 / 0068530A1 showed no possibility of shielding the shooter's face from the bolt because the bolt does not move into the cavity of a snap-on cheek piece, which has the disadvantage that, due to the length of the bolt travel and the cheek piece located at the end of the bolt travel, the length of the weapon is adversely increased, which impairs the handling and maneuverability of the weapon.

[0020] The ability to retract the breech into the cavity formed under the base leg by the stock cheek is suitable for all types of breech mechanisms, i.e., for example, straight-pull breech mechanisms, but also angle-pull breech mechanisms.

[0021] A particular advantage of this design is that the longitudinal movement of the cheek piece from the rear of the buttstock towards the front is limited by a locking device, which in a preferred embodiment consists of two symmetrical push buttons arranged in a straight line opposite each other. The push buttons are spring-loaded and slidably mounted in a continuous recess, designed as a transverse bore, in their direction of actuation, and can be released by pressing them with a finger.

[0022] In a preferred embodiment, the cheek piece is automatically locked in place by means of a locking mechanism such that the push buttons, in the locked position, are spring-loaded and protrude outwards beyond the lateral plane of the buttstock, and when the cheek piece is slid onto the longitudinal guide on the buttstock, the push buttons are spring-loaded and move inwards, so that manual operation of the push buttons is not necessary when sliding the cheek piece onto the buttstock.

[0023] Several sliding guides, aligned in the direction of fire and parallel to each other in the height adjustment direction, are located on the inside of the cheek piece. These guides cause the spring-loaded push buttons of the locking mechanism to be pressed inwards. The buttons remain pressed inwards in the released position until the adjustable cheek piece is fully slid onto the longitudinal guide at a specific, selected height setting. Afterward, the spring-loaded push buttons on both sides spring outwards, and their locking edges secure the rear of the cheek piece. This enables automatic locking of the cheek piece onto the buttstock after it has been slid onto the cheek piece.

[0024] To remove the cheek piece from the buttstock, the two opposing spring-loaded push buttons are preferably pressed inwards into the transverse bore in the buttstock against the spring force using the fingers of one hand to release the locking mechanism. This disengages the locking edges on the push buttons from the complementary stop surfaces on the rear face of the cheek piece, allowing it to be pulled off the buttstock from the longitudinal guide with minimal force. This eliminates the need for two-handed operation, as is common with prior art cheek pieces, which is a significant advantage.

[0025] The double-sided guidance of the height-adjustable cheek rest on the guide surfaces of the buttstock results in particularly stable sliding guidance and a particularly secure fit. This is achieved by the cheek rest abutting against corresponding fixed stops on the buttstock at the front and supporting itself against the locking edges of the push buttons at the rear, thus creating a longitudinal preload on the cheek rest. It is therefore held in its detent position by spring-loaded sliding pressure.

[0026] In a particularly preferred embodiment, it is provided that the two push buttons enable locking to the rear, i.e., to secure against displacement to the rear, whereas the forward displacement protection is achieved by stops on the buttstock-side mounting grooves on the rear side, i.e., below or next to the push buttons.

[0027] This means that the symmetrically adjustable cheek rest is held without play on the buttstock, which is a significant advantage over the state of the art.

[0028] According to a further feature of the invention, in another embodiment it is provided that the locking against rearward displacement at the buttstock is effected by stop surfaces on the two spring-loaded push buttons, but that the locking against forward displacement is effected on the front sides of the receiving grooves on the buttstock.

[0029] This is a variant compared to the embodiment described first.

[0030] It may be provided that the spring-loaded push buttons with corresponding beveled wedge surfaces rest against associated opposing wedge surfaces of the adjustable cheek piece in order to enable a pre-tensioned sliding lock of the cheek piece on the buttstock due to the spring force of the push buttons.

[0031] The draft angle, that is, the inclination in the direction of movement, would then be at the holding surface of the respective push button, which automatically springs into its locking position when it has been passed over by the cheek piece.

[0032] If a preferred example is described in the following character description, possible generalizations should be pointed out. 1. The cheek piece could also be slid onto the buttstock from the front (opposite the direction of fire). 2. The cheek piece could also be slid onto / received via angled grooves (perpendicular to the horizontal) in the buttstock and cheek piece (this applies to both directions). 3. The operating elements of the locking device described as push buttons are to be understood in a general sense. Therefore, push buttons, or more generally, operating buttons or slide switches, could be used instead of push buttons.

[0033] 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.

[0034] 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," "according to the invention," 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.

[0035] 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.

[0037] According to Figures 1 and 2 The hunting and sporting weapon essentially consists of a gun barrel 1, which is connected to a system box not shown in detail, the system box itself being connected to the forend 8.

[0038] In a manner known per se, a breechblock 2 is associated with the barrel 1, which in the illustrated embodiment is designed as a straight-pull breechblock, wherein the weapon has a butt plate 4 on the buttstock 5 in a manner known per se and, according to the invention, a height-adjustable and removable cheek rest 3 which is attached to the buttstock 5.

[0039] In a manner known per se, a trigger 7 is provided for firing a shot, and furthermore a pistol grip 6 in which a manual cocking mechanism 9 is arranged, which is intended for cocking and decocking the weapon. The firing direction is in the direction of arrow 32.

[0040] According to a preferred feature of the invention, the bolt 2 is designed to move into the upper cavity formed by the buttstock 3, thus making it possible for the first time to significantly shorten the length of the weapon without having to accept the disadvantages of bullpup firearms. A bullpup design is a type of handgun in which the chamber is located behind the grip and trigger. The German term for this design is "Hinterschaftlader" (literally "back-end loader").

[0041] In Figure 3 The weapon is depicted from the right side, with detail A, which is in Figure 4As shown in the enlarged image, it can be seen that the rear part of the cheek piece 3 rests on spring-loaded push buttons 10, 11 arranged on the right and left sides, preferably under preload directed in the direction of firing 32, wherein the cheek piece 3 has retaining ribs 23 directed inwards on its rear side, which are supported on associated, oppositely directed retaining surfaces 24 on the stock-side push buttons 10, 11.

[0042] Since the cheekpiece 3 is a longitudinally symmetrical U-profiled part, it is sufficient to describe only one side of the cheekpiece. This also applies to the two sides of the buttstock 5, which is at least in the area where the cheekpiece 3 rests, a longitudinally symmetrical part, for which it is sufficient to describe only one side.

[0043] The general description indicated that the retaining ribs 23 and the opposing retaining surfaces 24 can be inclined (conical) in the direction of movement in order to utilize the spring force of the push buttons 10, 11 so that the jaw 3 in the locking position is under spring tension on its sliding guide in the receiving grooves 16 (see Figure 13 ) is held.

[0044] However, the invention does not depend on this. In another embodiment, the invention can provide that the corresponding surfaces of the retaining ribs 23 and the snap-button-side retaining surfaces 24 are perpendicular to each other, thereby enabling a locking action with as little play as possible.

[0045] If, on the other hand, the mutually associated, complementary surfaces of retaining ribs 23 and snap-button-side retaining surfaces 24 are chamfered, a spring-loaded preload of the cheek piece 3 occurs in the area of ​​the buttstock-side receiving grooves 16, because it is held spring-loaded and without play in its detent or locking position.

[0046] A further advantage of the snap-on fastening with snap fasteners 10 and 11 is that these protrude only slightly beyond the outer surface of the buttstock 5 and are therefore barely visible and do not interfere with the operation of the weapon. They can be operated with the fingers of one hand because they are precisely aligned and symmetrically opposite each other, spring-loaded and slidably within a transverse bore in the buttstock.

[0047] Advantageous in the executions according to the Figures 3 to 7The advantage is that, for the first time, it is now possible for the buttstock cheek piece 3 according to the invention to be mounted on the buttstock 5 in the direction of arrow 17. That is, it can be slid onto the buttstock from the rear part of the buttstock 5 towards the front, in the direction of arrow 32, at a predetermined height setting, and is preferably locked onto the buttstock without play after being slid on.

[0048] According to Figure 7 It is preferred that the adjustable cheek rest 3 is height-adjustable in the directions of arrow 38, which means that the inwardly directed, symmetrically opposite and aligned ribs 15 of the cheek rest can be inserted into corresponding receiving grooves 16 that are parallel to each other and have the same vertical distance from each other. The receiving grooves are therefore arranged symmetrically and aligned with each other on two opposite sides of the buttstock 5.

[0049] The Figure 7 The vertical arrow direction 38 shows the possibility of selecting the height of the cheek piece 3, because with its inwardly directed ribs 15 it can be slid into the receiving grooves 16 on the two side surfaces of the buttstock 5 at different heights and locked in place there.

[0050] In this case, it will be according to Figure 7 Preferably, the snap fasteners 10, 11 each have a sliding ramp 28, 29, so that when the cheek piece 3 is slid onto the buttstock 5, the snap fasteners automatically spring inwards and move into their unlocked position. It is further preferred if, according to Figure 21On the inside of the cheek piece, there are 3 inclined insertion ramps 25 which have the same angle as the sliding ramps 28, 29 on the push buttons 10, 11, in order to allow easy sliding and thus easy actuation of the push buttons 10, 11 when sliding the cheek piece onto the buttstock 5.

[0051] This makes it possible for the first time to slide the cheek piece 3 onto the buttstock with one hand, without having to perform a complicated vertical locking action, as required by the prior art, which necessitates two-handed operation. This was identified as a disadvantage of the prior art.

[0052] The Figures 8 to 10Figure 1 shows the mechanics of the spring-loaded push buttons 10, 11 in detail. The two push buttons 10, 11 are arranged in a horizontal recess 19, designed as a transverse bore, which extends through the entire buttstock 5, wherein the two push buttons are biased in opposite directions into their outwardly directed locking position by a compression spring 12 arranged in the recess 19.

[0053] The locking position is therefore determined by the direction of arrow 18 to the right and left, while the release position is defined as directed inwards against the spring force of the compression spring 12.

[0054] In this case, it will be according to Figure 10 preferably, if a nose 13, 14 is formed on the lower side of each respective push button 10, 11, which rests against inner surfaces on the buttstock 5 to prevent the push buttons 10, 11 from falling outwards in the direction of arrow 18 under the force of the compression spring 12.

[0055] Furthermore, the pushbuttons 10, 11 form stop surfaces 20, 22 which can be brought into contact with corresponding stop surfaces of a travel limiting sleeve 21 to prevent the pushbuttons 10, 11 from being displaced too far into the recess 25 against the spring force of the compression spring 12. This limits any inward movement of the pushbuttons 10, 11.

[0056] This also prevents each push button 10, 11 from being moved inwards by the fingers of one hand alone and then disappearing into the recess 19. The travel limiting sleeve 21 has a locking rib 33 which is firmly anchored in the buttstock 5.

[0057] Thus, according to Figure 10It is possible to simultaneously actuate the two opposing, aligned and sliding push buttons 10, 11 with the fingers of one hand in the directions of arrow 18 in order to release the shaft jaw that is pushed on and locked there.

[0058] The Figures 11 to 13 This shows the play-free longitudinal guidance of the cheek piece 3 on the buttstock 5. This is according to Figures 12 and 13 It is provided that on both sides of the buttstock 5 there are receiving grooves 16 which are arranged in a vertical grid dimension and allow the cheek piece 3 to be inserted into one of the different receiving grooves 16 of the buttstock 5 in different height settings according to the arrow directions 38 with its inwardly directed ribs 15.

[0059] This shows Figure 13For example, the two upper mounting grooves 16 on the buttstock are left free, which results in the cheek piece being pushed onto the buttstock 5 in its lowest position. If, however, it is pulled off the buttstock and, for example, in the direction of arrow 17 towards Figure 7 and, if pushed onto the cheek rest at a different height according to arrow 38, the ribs 15 of the cheek rest 3 can, for example, be inserted into the upper mounting grooves 16 on the buttstock, thereby achieving a higher height setting for the cheek rest on the buttstock. The indexing dimension is indicated by reference numeral 35, which allows for adjustment of the height position, and the total adjustment range is given in Figure 12 indicated with reference number 34.

[0060] As a safeguard, according to Figure 20To ensure that at least two ribs 15 arranged one above the other on the inside of the buttstock are inserted into at least two complementary receiving grooves 16 on the buttstock, the upper distance of the sliding surface 37 to the first, upper receiving groove 16 in the buttstock 5 is different from the vertical grid dimension 35 between the receiving grooves. This ensures that at least two horizontally arranged ribs 15 of the buttstock 3 always engage in at least two receiving grooves 16 on the buttstock 5 and are longitudinally displaceable there.

[0061] The Figures 14 to 16 The figures show different views of the symmetrical cheek piece 3 according to the invention. In this case, Figure 14 It can be seen that the retaining rib 23 arranged on the front side at the rear end of the shaft jaw 3 is for locking onto the push buttons 10, 11 according to Figure 4 and as described therein.

[0062] The ribs 15, arranged internally and aligned opposite each other, are also visible.

[0063] Further details of the arrangement can be found in the Figures 15 to 16 . In the illustration of the jawbone 3 from the front side, it can be seen that the retaining ribs 23 are vertically oriented and cooperate with the associated snap fasteners 10, 11 and their retaining surfaces 24, whereby the retaining surfaces 24 of the snap fasteners 10, 11 can be brought into contact along the entire length of the retaining ribs 23 of the jawbone.

[0064] This results in a consistent locking surface, regardless of the height adjustment of the cheek rest on the buttstock 5.

[0065] In a preferred embodiment, according to Figures 14 and 15Above the ribs 15 provided for height adjustment, further stop ribs 26 are provided, which are arranged symmetrically and in alignment with each other on the inner sides of the shaft jaw 3 and serve as sliding surfaces with the associated sliding surfaces 37 according to Figure 25 to cooperate on the buttstock 5.

[0066] The meeting of the corresponding stop ribs 26 of the cheek rest 3 with the sliding surfaces 37 on the buttstock 5 thus serves for position orientation and to determine the lowest position of the cheek rest, because in this lowest position the upper stop ribs 26 on the cheek rest 3 then lie on the sliding surfaces 37 of the buttstock and are movable there.

[0067] From the Figures 18 to 22It follows that the shaft jaw 3 has an overall U-shaped profile, which is approximately saddle-shaped in its design and has a rounded roof surface, with the outer surfaces of the shaft jaw 3 according to Figure 20 The cheek rest 39 is designed so that the shooter's cheek rests against it when firing the weapon, thus bringing the aiming eye into the line of sight more quickly and easily.

[0068] This makes it clear that, due to the symmetrical design of the cheek rest 3, the cheek rests 39 are also symmetrically designed, so that they are equally suitable for left- or right-handed operation of the weapon.

[0069] Furthermore, at Figure 20It should be emphasized that the inner cavity 27, formed above the ribs 15 in the cheekpiece 3, constitutes a receiving space designed to allow the weapon's bolt to move into the cavity 27 during cycling and be protected there. This reduces the usable length of the weapon—because the length of the cheekpiece and the cycling travel partially overlap—and also protects the cheekpiece 3 from dirt and debris entering the bolt carrier and the rear of the action.

[0070] It is advantageous that the shooter cannot injure himself during reloading by the bolt moving longitudinally backwards, because the bolt moves into the cavity 27 of the cheek rest 3 during reloading and does not come into direct contact with the shooter's cheek or face, as is the case with other weapons.

[0071] The side parts 30, 31 of the cheek piece 3 are therefore symmetrical and also cover parts of the buttstock 5.

[0072] The Figures 23 to 25 Further details of the buttstock attachment are shown, revealing that the receiving grooves 16 are arranged on surfaces of the buttstock 5. These receiving grooves 16 can be machined into the material of the buttstock, but they can also be applied to the buttstock 5 as separate parts.

[0073] Furthermore, in Figure 23 compared to Figure 24 It can be seen that the transverse recess 19 in the buttstock accommodates the push buttons 10, 11, with position 36 in Figure 24 The figure shows that the retaining rib 23 of the shaft cheek 3 rests on the front edge at the recess 19, where the snap fasteners 10, 11 are spring-loaded and slidably mounted.

[0074] Thus, it is clear that the retaining rib 23 of the cheek piece 3 is held in this area of ​​the recess 19 by the push buttons 10, 11 in any desired height settings.

[0075] The Figure 25 This shows the buttstock-side receiving grooves 16 in the specific grid dimension 35 (see Figure 12 ).

[0076] Thus, the ribs 15 of the cheek piece 3 can be inserted into the various opposing and aligned receiving grooves 16 on the buttstock 5 at different height settings and locked there.

[0077] In the illustrated embodiment, the receiving grooves 16 on the rear of the shaft are open vertically outwards in a horizontal direction and the complementary ribs 15 engaging there also have a rectangular profile.

[0078] The invention is not limited to this. In another embodiment, the grooves may be dovetail-shaped, meaning they have undercuts, and the corresponding ribs on the buttock side may also have a profile adapted to this design in order to prevent the groove-rib guide from spreading apart or being unintentionally removed. These are therefore undercut grooves that hold the buttock parts even better and protect them against lateral spreading.

[0079] In principle, any known longitudinal guide with a specific profile of the receiving grooves 16 in the buttstock 5 can be present with a complementary profile of the longitudinally displaceable ribs 15 in the cheek piece 3. Suitable pairings 15, 16 include not only dovetail guides but also interlocking semicircular, square, triangular, or prism guides.

[0080] Likewise, the kinematic reversal of all described longitudinal guides is possible, in which the receiving grooves 16 are located in the cheek piece 3 and the longitudinally displaceable ribs 15 are located in the buttstock 5.

[0081] Within the framework of this kinematic reversal, the described locking device with the push buttons 10,11 can also be arranged in the cheek piece 3 and the cooperating, opposing and complementary parts 25, 26 in the buttstock. Drawing legend
