HUNTING OR SPORTING FIREARM WITH A LOW-MOUNTED LOCK

Description

[0001] The invention relates to a hunting or sporting weapon with a low-profile breech according to the preamble of claim 1.

[0002] The invention relates in particular to a hunting or sporting weapon with repeating function, in which the ammunition or cartridges are reloaded from a magazine into the cartridge chamber in the weapon barrel via a manually operated mechanism, wherein a breechblock which can be operated via a bolt handle and which, depending on the actuation, covers the breech guide or the magazine well of the weapon and locks a breech head in the weapon barrel or, in the open position, performs a reloading.

[0003] A disadvantage of, for example, the straight-pull bolt action of the Blaser R8 is that a relatively large bolt housing is required. This is because, on the one hand, the entire mechanism for the bolt handle and its various functions must be housed within the bolt housing, and the bolt must cover the entire magazine well of the weapon. On the other hand, the firing pin spring is arranged coaxially with the firing pin within the bolt housing, which means that the bolt housing must be large, i.e., tall, because the firing pin spring is aligned coaxially with the firing pin and almost completely fills the space within the bolt housing.

[0004] The same locking principle is also known from the Beretta BRX1, which has the same disadvantages as the locking mechanism of the Blaser R8.

[0005] US Patent 2020 / 049436 A1 depicts a repeating hunting or sporting firearm in which ammunition is loaded from a magazine into the chamber via a manually operated mechanism. The bolt is operated by a bolt handle and, depending on its position, covers either the bolt carrier or the magazine well, locking a bolt head in the barrel or, in the open position, reloading the firearm. A locking chamber is also shown, housing the firing pin, which is connected to a firing pin spring. This locking chamber is located within a straight, cylindrical receiver.

[0006] This resulted in such well-known and relatively tall breechblock housings making the weapon unwieldy, heavy and not visually appealing, and restricting ease of use.

[0007] The invention is therefore based on the objective of further developing a hunting and sporting weapon with a breech of the type mentioned above in such a way that a low breech housing can be achieved, which offers advantages in the handling of the weapon.

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

[0009] According to the invention, the breechblock is designed as a height-stepped breechblock housing, consisting of a front, higher part corresponding to the height of the weapon barrel, to which a height-reduced part is connected via a recess.

[0010] This height gradation of the breechblock housing makes it possible for the first time to move the rear part under the (low) buttstock cheek piece and to significantly reduce the moving mass of the breechblock.

[0011] It was recognized that the low overall height of the breechblock could be achieved by modifying the arrangement of the firing pin and firing pin spring. A preferred feature of the invention is that the firing pin spring is no longer arranged coaxially to the firing pin, but offset vertically below the longitudinal axis of the firing pin, namely in a Z-arrangement.

[0012] It is preferred that the firing pin spring be arranged vertically offset downwards, below the firing pin. The firing pin axis is always coaxial with the bore axis of the barrel or chamber. Since, in the prior art, the firing pin spring axis was also coaxial with the firing pin axis, this resulted in the undesirable high profile of the receiver.

[0013] This is where the invention comes in, which provides that the axes of the firing pin and the firing pin spring are preferably parallel to each other, but have a relative height offset. This allows the firing pin spring to be arranged in a rear, lower-profile section of the breechblock housing, and it is no longer necessary to design this rear section with the same height as the front section of the breechblock housing.

[0014] This makes it possible for the first time to design the receiver – at least its rear section – with a low profile. Because of this low profile, the rear part of the receiver can slide under the buttstock during cycling, which is a significant advantage. This also allows for a new arrangement of the magazine well in the front of the buttstock, thus considerably reducing the overall length of the weapon. Furthermore, because the track for the receiver's sliding mechanism can now also be relocated to the buttstock – since the rear of the receiver can slide under the buttstock – the rear sections of the receiver can also be moved into the buttstock. This results in the following additional advantage.

[0015] Another disadvantage of the straight-pull action, for example in the Blaser R8 or the Beretta BRX1, is that the receiver, with its end facing the shooter, extends towards the shooter's face and cannot be covered by a cheek rest because it is too tall. This means that the rear of the receiver and the action housing must end well in front of the buttstock, resulting in an undesirably long weapon. This disadvantage is eliminated by the stepped, low-profile receiver.

[0016] The technical teaching of the invention makes it possible for the first time to design only the front area of ​​the breech housing at the usual height, because the firing pin must always be coaxial with the bore axis.

[0017] The entire mechanism of the breech control can be housed in the raised part of the breech housing, while a rear, lower part adjoins the raised, front part of the breech housing, which can run under the buttstock cheek piece and is preferably covered by it on all sides.

[0018] This relocates the rear longitudinal displacement area for the sliding bolt housing below the buttstock cheekpiece, which is a significant advantage over known hunting or sporting rifles with straight-pull bolt action. Such a cheekpiece can also be referred to as a chin rest, and a preferred feature of the invention is that the rear part of the bolt housing moves below the cheekpiece during the cycling process and therefore does not approach the shooter's face with its rear end.

[0019] A further advantage of the inventive measure is that, due to the low overall height resulting from the radial offset of the firing pin spring relative to the firing pin, it is possible to provide a very short bolt housing (also called bolt body or bolt control housing), in the front part of which the manually operated, pivoting bolt handle with all its functions is arranged and also includes the bolt head receptacle. All functions of the bolt handle are, so to speak, relocated to the tall, short front part of the bolt housing, while in the rear part of the bolt housing there is a recess to a low overall height, which gives the rest of the bolt a low overall height, so that, due to this low overall height, the bolt can retract below the buttstock cheek piece.

[0020] The height offset achieved by arranging a radially offset firing pin spring is preferably about 12 mm, whereby a range of 5-25 mm can be provided.

[0021] To achieve the preferred height offset of approximately 12 mm, the breechblock is designed with a smaller rear section, allowing its rear portion to be positioned below the cheek piece. The height of this rear section is preferably 16 mm, although a range between 5 and 25 mm is possible.

[0022] The resulting setback of 12 mm is sufficient to allow the reduced-height breechblock to be retracted under the cheek piece, which was not possible with previously known straight-pull breechblocks.

[0023] The advantages of the invention result from a height-graduated locking housing in which the firing pin spring and the firing pin form a Z-shaped arrangement offset in height.

[0024] A further preferred feature of the invention is that the entire locking control mechanism and the receptacle for the locking head are housed in the taller part of the locking housing, which preferably has a height of approximately 30 mm and a length of approximately 30 mm within a preferred range of 15 to 40 mm, which was previously unknown.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] They show: Figure 1 : Perspective side view of a hunting and sporting weapon with the breech closed. Figure 2 : One detail A after Figure 1. Figure 3 : A front view of the breechblock housing with the breechblock head inserted. Figure 4 : A section along line BB in Figure 3 . Figure 5 : A representation similar to Figure 3 with the locking head removed Figure 6 : A cut along line BB in Figure 5 . Figure 7 : A perspective side view of the Z-arrangement of firing pin and firing pin spring

[0029] In the Figures 1 and 2Figure 1 shows a possible embodiment of a repeating hunting and sporting rifle, featuring a barrel 1 on which a telescopic sight mount 2 is attached. A bolt 3 is located in the receiver 12 of the rifle, behind the telescopic sight mount 2, with the buttstock 5 covered by a cheekpiece 4. Optionally, the buttstock 5 can also be covered at the front by a rear butt plate 6. The barrel 1 is rigidly connected to a monoblock 11, and the bolt 3 engages the monoblock 11 at its front end and can be locked to it.

[0030] In the area of ​​the pistol grip 14, a central control element for the breech mechanism is arranged, which is designated as the palm release 15 and also serves, among other things, as a manual cocking mechanism for tensioning the firing pin spring 28. The trigger guard 13 with the trigger 7 is located in the front part of the pistol grip 14.

[0031] The palm pusher 15 can be spring-loaded and pressed inwards to be moved into its position under the load of a spring (not shown). Figure 1 to swivel out into the depicted resting position.

[0032] The central control element in the form of the palm pusher 15 is designed as a hand cocking device and as a safety element for certain functions of the bolt handle 10 and the locking control.

[0033] The bolt handle 10 has a bolt handle ball 9 at its freely pivoting end and is arranged laterally on the bolt housing 30. The forend 8 connects to the receiver 12.

[0034] Out of Figure 2 is in connection with Figure 4It is evident that the breech housing 30, which is part of the breech 3, has a specific front height that determines the system height of the monoblock 11. The raised portion of the breech housing 30 extends only a short axial length 24 to the rear and transitions into a recess 31 that reduces this height and extends over the entire rear axial length of the breech housing 30. The height offset is related to the distance 23 in Figure 2 shown. The height offset has a preferred dimension of 12 mm, but can range between 5 and 25 mm.

[0035] Thus, the rear part of the shutter 3 lies below the upper edge of the shutter housing part 30a by the height offset with respect to the distance 23.

[0036] The closure housing therefore preferably consists of three interlocking and adjoining parts, namely the front raised part 30a, a middle part 30b of low height and an end part 30c which preferably adjoins the middle part at the same height.

[0037] This results in an overall length of the bolt 3, which is short in its front section 30a. Due to their reduced height, the sections 30b and 30c can move under the cheek piece 4 during the cycling process. This means the cheek piece 4 covers the shooter's face, preventing the rear sections 30b and 30c from coming unprotected and approaching the shooter's face. Thus, the shooter is protected by the cheek piece 4 covering.

[0038] A particular advantage is that the breech housing 30 transitions at its rear, axial end into the roof-shaped part 30c of low height, which together with the preceding part 30b preferably forms a continuous part of low height and thereby ensures optimal coverage of the breech opening or the breech guide of the weapon during the cycling process.

[0039] This results in a closed system for the weapon, which is protected against contamination because the bolt 3, with the extended part 30c of the bolt housing, does not expose any open parts or areas of the weapon, even during the cycling process. During the cycling process, part 30c of the bolt housing 30 moves under the cheek piece 4, and when the bolt 3 is closed, the bolt housing 30 covers the entire opening, which can represent the magazine well in the receiver 12. Figures 4 and 6It is shown that the increased length 24 of the shutter control housing 30 constitutes only one third of the total length of the shutter 3 without including the length 26 of part 30c.

[0040] From the Figures 3 to 7 Further details of the low-profile closure 3 according to the invention can be found in the following. First, in Figure 5 The front view of the breechblock 3 with the missing breech head 25 and the firing pin 19 is shown, while the Figure 3 the locking head 25 with the firing pin 19 passing centrally through the locking head 25.

[0041] The low overall height of the breech housing 30 is achieved by the Z-shaped, vertically offset arrangement of the firing pin spring 28 relative to the firing pin 19.

[0042] The firing pin spring 28 is after Figure 4 and 7One end of the firing pin spring 28 is received in a pin- or sleeve-shaped firing pin spring receptacle 20, which forms a first axial axis 17. The other end of the firing pin spring 28 is supported against a counter bearing 27 on the underside of the breechblock housing 30.

[0043] The front end of the pin- or sleeve-shaped firing pin spring receptacle 20 is attached to one end of a transverse firing pin bridge 21, which is located approximately in the region of the recess 31 of the breech housing 30. The firing pin bridge 21 is connected to the firing pin 19 at its other end. The firing pin 19 has an axis 16 that is offset vertically by a distance 18 from the axis 17 of the firing pin spring 28. The two axes 16, 17 are preferably parallel to each other. However, the invention does not require this; it is possible for the axis 17 of the firing pin spring 28 and its coaxial extension of the firing pin spring receptacle 20 to form an acute angle with the axis 16 of the firing pin 19. The axis 17 of the two parts 20, 28 can therefore also be slightly inclined.

[0044] It is preferred that the transverse axis 32 through the firing pin bridge 21 is perpendicular to the two coaxial axes 16 and 17. It is preferred that the axis 32 is oriented vertically. However, this is not essential to the invention. It is also possible that the axis 32 through the firing pin bridge 21 is oriented slightly obliquely to the vertical.

[0045] Therefore, further angles can be used to reduce the height of the breechblock housing, such as an angle of 45° to the vertical of the weapon.

[0046] The rear end of the firing pin 19 is secured in the firing pin bridge 21 by a tension pin 22.

[0047] Because of this height offset 18, which results from the offset of the two longitudinal center axes 16 and 17 by the firing pin spring receptacle 20 and by the firing pin 19, the desired low-profile design of the breechblock 3 is achieved, as shown in Figures 1 and 2 depicted.

[0048] The overall length of the weapon could be significantly reduced while maintaining comparable firing performance, caliber and dimensions to a conventional weapon, and it was also possible to minimize the optical axis of the telescopic sight to the bore axis, both of which are achieved by the low breech according to the invention.

[0049] The firing pin bridge 21 or the firing pin spring receptacle 20 is generally installed in the breechblock housing 30 in a rotationally fixed or positionally oriented manner relative to the firing pin 19. The position of the firing pin 19 is defined as being in the center of the breechblock head 25 or in the center of the bore axis of the barrel 1. This means that the axis of rotation is the firing pin, and the firing pin bridge with the firing pin spring receptacle can rotate around it. Reference symbol list
