Definitions

  • the subject of the invention is a bolt head of a hunting or sporting weapon as part of a weapon bolt according to the preamble of patent claim 1.
  • the breech is an assembly of a breech loader and closes the barrel to the rear.
  • the closure prevents propellant gases from escaping to the rear. It must be stable enough to withstand the pressure of these gases.
  • the cartridges or cartridges are fixed in the barrel by the breech and the seal is achieved by lidding the case material. The breech must therefore maintain the seal or support of the cartridge during the firing and must not open before the gas pressure has dropped to a safe value.
  • the lock can take on other functions such as loading, firing, securing and unloading the weapon.
  • the locking elements are not attached perpendicular to the axis of rotation, but rather at a slightly helical angle.
  • the rotation when unlocking the shutter causes it to move back by 1 to 2 mm, which loosens the sleeve via the extractor, this is also called forced extraction. This primary extraction significantly reduces the effort needed to reload.
  • Swivel head locks work similarly to cylinder head locks.
  • an exchangeable bolt head is particularly advantageous when a caliber group change is to take place, which means that when a specific first caliber is changed to a second caliber, the bolt head must be replaced, as does the barrel and the magazine. Further advantages of interchangeable bolt heads are that when the bolt head is removed, the weapon is rendered unusable and this represents a special safety feature.
  • Interchangeable bolt heads for hunting or sporting weapons have become known in several versions.
  • the Blaser R8 weapon type uses a bolt head that can be changed, but requires the bolt slide to be completely removed.
  • the bolt head With the Blaser R8 weapon, the bolt head is changed in such a way that the entire bolt slide must be removed towards the rear in the direction of the buttstock by pulling it completely out of the weapon and pulling it off. It must then be turned 180° until its underside is accessible, and on the underside a locking latch called a chamber lock is accessible.
  • the locking latch is operated with your finger when swiveling up, in order to then pull the locking head out of the locking slide that has been removed from the weapon after this chamber lock has been activated.
  • cylinder closures such as e.g.
  • a bolt head is installed in a completely inaccessible manner, which means that the entire chamber must also be removed in order to make the bolt head accessible and ultimately be able to be removed.
  • the problem of changing calibers is also addressed DE 39 06 496 A1 .
  • the publication proposes a barrel changing unit, a cylinder lock changing unit and a magazine changing unit.
  • the barrel is first removed with the breech open.
  • the locking head is then removed by removing a stud screw from the guide bearing taken out.
  • this comes with the disadvantage that the barrel must be completely removed to access a stud screw holding the bolt head.
  • the invention is therefore based on the preamble of independent claim 1 DE 39 06 496 A1 or the weapon type R8 from Blaser or the weapon type Sauer 404 from Sauer, which describe a hunting or sporting weapon with a bolt consisting of several components from the group of cylinder bolts or straight-pull bolts, which consists of at least one firing pin or a hammer, a firing pin spring, an extractor and a breech head, the breech head being interchangeably received with a holding means in a breech-side receiving sleeve, the breech head being fastened in a breech slide that can be moved and locked along the weapon.
  • the invention is therefore based on the object of developing a breech head of a hunting or sporting weapon in such a way that it can be replaced without removing the breech slide or the chamber or the barrel.
  • the invention is characterized by the technical teaching of claim 1.
  • the advantage is achieved of making the locking head accessible from the front without removing the locking slide or the chamber in order to move it from a locking position to a removal position.
  • an advantageous feature of the invention is that, according to the invention, the breech head can be removed and installed in the firing direction, ie in the axial direction of its longitudinal extent, without there being a need for the breech slide or the chamber or the barrel itself to be removed from the weapon. This means that it is no longer necessary to make the locking head accessible from the underside of the removed locking carriage in order to be able to remove it.
  • breech head can be quickly removed without the need for further removal measures, such as the removal of the breech slide or the chamber.
  • a manually operable locking button for the releasable and lockable fixing of the closure head is accessible on a receiving sleeve arranged on the front of the closure head.
  • latching button can be actuated with a finger pressure, the latching button being arranged in the area of a receiving sleeve, which is part of the receiving housing for the closure head.
  • Such a locking button is preferably spring-loaded and preferably works together with a closure element, which in a preferred embodiment consists of a spring-loaded, radially displaceable wedge which, in the closed position, creates a lock between the inner circumference of the receiving sleeve and the outer circumference of the closure head.
  • a closure element which in a preferred embodiment consists of a spring-loaded, radially displaceable wedge which, in the closed position, creates a lock between the inner circumference of the receiving sleeve and the outer circumference of the closure head.
  • a pin-shaped or round-shaped wedge can also be used.
  • the latching button for releasably locking the locking head is designed as a separate component. This is the subject of claim 3. This is particularly preferred for types of weapons that do not have an extractor.
  • the locking button is part of the extractor. This is the subject of claim 4.
  • the extractor is, in a known manner, part of the locking systems of firearms.
  • Other names are extractor claw or extractor hook.
  • the extractor is typically claw or hook-shaped and is resiliently mounted in the movable part of the locking system.
  • the claw or hook engages through a recess in the idle state (lock is locked).
  • end of the cartridge chamber into the designated groove (edge) or edge of the cartridge case in order to pull it out of the cartridge case when the movable part of the breech system moves backwards after the shot has been fired.
  • the cartridge case then hits the ejector, which moves it out of the breech system and thus out of the weapon.
  • the extractor can also be missing because it is not needed. There the gas pressure pushes the empty case backwards out of the chamber against the bolt head, thus initiating the repeating cycle.
  • the extractor is preferably a two-armed swivel button, which serves to extract the cartridge in the chamber when the breech slide or chamber is opened and to eject it using the ejector.
  • the extractor which is already present in a weapon, has a dual function, namely firstly for extracting the fired cartridge and secondly for actuating the catch for the bolt head.
  • the previously mentioned locking button is therefore part of the extractor.
  • a separate actuation button can be provided for unlocking the locking head.
  • a spring-loaded lock is provided for the closure head, which lock works with a locking wedge which can be displaced in the radial direction in the closure head and which is displaceable and spring-loaded in an associated radially aligned locking groove in the closure head and a locking connection with the receiving sleeve on the locking side.
  • This locking connection is preferably designed to be form-fitting.
  • the invention is therefore not limited to such a spring-loaded locking wedge that can be actuated radially from the head side of the closure head and the receiving sleeve.
  • latching latching devices arranged elsewhere can also be used for the closure head, in particular ball latching devices.
  • the spring-loaded balls engage in the radial direction in an associated annular receiving groove on the rear side of the closure head and thus establish a locking connection with the receiving housing. This locking connection is actuated by axial or vertical pressure or tension on the locking head.
  • an external thread is arranged on a rear axial extension of the closure head, which interacts with an associated internal thread in the area of the receiving sleeve.
  • a certain position-locked rotational position can then be assumed by rotating the locking head in the receiving sleeve, with which the locking head is secured in position or unlocked.
  • the threaded screw connection can also be designed as a high-helix thread or as a bayonet screw connection.
  • the term “ejection opening” is understood to mean the free space that is created when the breech slide or the chamber in which the receiving sleeve is arranged together with the breech head, which is housed there in a detachable and lockable manner, is pulled backwards towards the buttstock, so on to open the ejection opening. There is then the possibility of using a finger or, alternatively, a tool, to pull the bolt head forward out of the ejection opening via the ejection opening in the firing direction and to exchange it for another bolt head.
  • the invention has the advantage that no additional weapon parts - e.g. the bolt slide or the chamber or the barrel itself - have to be removed or changed, there is the further advantage that the bolt guide for the bolt slide on the weapon can be made very stable and compact because there is no need to remove the bolt slide or the chamber .
  • the breech slide or the chamber can therefore be guided over its entire length with close tolerances in an internal breech guide on the weapon side and thereby results in a particularly stable longitudinal guide for the breech slide or the chamber, while in the prior art this rail guide is disadvantageously extended towards the front, in order to be able to pull the breech slide out of the weapon-side rail guide, which is not necessary with the invention.
  • the bolt guide with the bolt slide or the chamber goes out into the rear, which additionally requires that the shooter-specific measures on the weapon have to be changed when the bolt slide or the chamber is removed.
  • the back of the stock must be folded in, which includes a shooter-specific adjustment of the stop.
  • the invention also lacks parts on the breech slide that disadvantageously protrude forward from the quickly removable breech head, as would have to be accepted in the prior art, which is considered to be disadvantageous, particularly in the case of the Blaser R8 weapon type.
  • These thin guide rails, which protrude forward over the locking head, can bend and thus massively impair the locking slide guide - which is already not precise and not stable - or cause it to jam.
  • the invention therefore solves the problem with particularly simple means of developing a quick-change breech head of a hunting or sporting weapon in such a way that it can be removed directly from the front of the breech slide or chamber that is moved to the rear from the ejection opening formed thereby and can also be used again directly can be, without the need to completely remove the slide or chamber or barrel from the weapon.
  • a hunting or sporting weapon 45 is shown, which in the exemplary embodiment shown consists of a weapon barrel 35 which forms a front weapon barrel muzzle 43.
  • the weapon barrel is covered in the front area by the forend 36 and ends in a barrel holder 30, which is also referred to as a monoblock.
  • the barrel recording 30 is included in the system box 33.
  • the system box 33 contains the magazine, not shown, as well as the shutter guide 25 for a shutter slide 46, which is in The arrow direction 18 enables the closure head to be removed from the closure head 1.
  • closure is according to the Figures 1, 2 , 3 and 4 opened, as can be seen in the view 54 with the opened ejection opening 47, the closure carriage 46 being moved backwards in the direction of the arrow 18 'in order to release the ejection opening 47, as shown in the detailed view 55 of 54.
  • the closure head 1 is also visible here, which according to the invention can be removed in the open ejection opening 47 without any additional aids and without tools.
  • Figure 5 shows the shutter carriage 46 in which a shutter housing 32 and a shutter guide cover 58 are arranged.
  • the closure housing 32 consists of a receiving sleeve 8, in the interior of which the closure head 1 is detachably and lockably accommodated, which, according to a preferred embodiment, can be accessed and replaced forwards in the firing direction without tools via the ejection opening 47.
  • the guides 57 and 56 are also shown, which slide in the guides 25 in the system box 33.
  • a trigger guard 37 with a trigger 38 mounted therein is attached to the system box 33, and there is preferably a pistol grip 39, the magazine preferably being arranged above the pistol grip 39 and not being shown in more detail.
  • the magazine is preferably arranged vertically in alignment below the ejection opening 47.
  • the magazine is therefore arranged above the pistol grip 39 and aligned with the ejection opening 47 on the system box 33.
  • a magazine not shown in detail, is in Firing direction is arranged in front of the pistol grip 39 and is arranged above the trigger guard 37, in which case the ejection opening 47 is also arranged above the trigger guard 37.
  • the closure carriage 46 with the forward-facing closure head 1 defines the right side of the ejection opening 47 and the closure head 1 preferably, without tools, from its closure-side receiving sleeve 8 in the closure carriage 46 can be removed.
  • the breech slide 46 with the forward-facing breech head 1 defines the left side of the ejection opening 47. This works for weapons with right-hand or left-hand systems.
  • the weapon 45 shown has, in a manner known per se, a buttstock 40 which is closed at the rear by a buttplate 41, with a vertically adjustable stock ridge 42 being arranged on the buttstock 40, which can be attached to rest on the shooter's cheek. This means that the optimal stop for the shooter is achieved.
  • the Figure 1 shows detail 29 of the view in Figure 2 , where further details of the invention can be found.
  • the breech head 1 can therefore be removed forward in the firing direction in the direction of arrow 18 when the ejection opening 47 is released by the displacement of the breech slide 46 in the direction of arrow 18 '.
  • the ejection opening 47 becomes free, and the left boundary of the ejection opening 47 is formed by the wall of the barrel receptacle 30, while the right boundary is at least partially formed by the receiving sleeve 8, so that the breech head 1 preferably emerges from this free space, without tools by actuating a The catch or locking button that will be explained later can be found.
  • FIGS. 6 to 10 show the locked state of the locking head 1 in a receiving sleeve 8, which is part of the locking carriage 46, it being pointed out that the locking slide 46 according to Figure 4 is guided in a weapon-side breech guide 25, which represents the slide guide for the breech slide 46.
  • the breech housing 32 can be moved as part of the breech slide 46 under the back of the stock 42, whereby the usable length of the weapon is significantly shortened. This allows a shorter buttstock 40 to be realized because the firing slide 46 with its locking guide 25 extends under the back of the stock 42 in the open position. This improves the handling of the weapon.
  • the locking position for the locking head 1 is characterized in that the locking head 1 is locked in a spring-loaded manner in the receiving sleeve 8 using a spring-loaded locking button.
  • this locking button is designed as an extractor 2, which means that the extractor 2 has a dual function, because on the one hand it serves to extract the cartridge from the cartridge chamber and on the other hand the extractor 2 preferably serves as a two-armed locking lever for the locking locking of the bolt head 1 in the receiving sleeve 8.
  • the extractor 2 which is designed as a two-armed lever, is provided on the front side with an actuating surface 19 on its front lever arm and by engaging this actuating surface with a finger, it can be lifted in the area of the extractor groove 19a in the direction of the arrow 12.
  • the opposite end of the lever engages with its nose, which is extended in the axial direction, into an assigned receiving groove on a locking wedge 5. It is actuated by downward pressure. This takes place against the force of a locking spring 10, which is in Figure 8 is shown.
  • the locking spring 20 pushes the lever end of the extractor 2 upwards, in the direction 13 ', whereby the locking position of the locking wedge 5 in the locking sleeve 8 on the locking side is spring-loaded in the locking groove 28, remains upright and remains secured even in the event of vibrations in order to avoid unintentional displacement when locked.
  • the entire locking device for actuating the closure head 1 is arranged in the closure head itself and is therefore removed when the closure head 1 is removed.
  • the extractor 2 is accommodated with its pivot axis 3 in the locking head 1, so that when the actuating surface 19 is actuated in the direction of the arrow 12, the locking wedge 5 is displaced downwards in the direction of the arrow 13. This is the unlocked position, which is in the Figures 11 to 15 is shown.
  • the number 9 shows the firing pin hole 9, through which the firing pin passes centrally through the bolt head 1.
  • the helical compression spring 14 is the ejector spring 14 for the ejector 10.
  • the pin-shaped ejector 10 ejects the cartridge held in the area of the bolt head 1 from the back after opening the breech slide or the chamber, the cartridge being held in the extractor 2.
  • reference number 4 shows a groove extending in the longitudinal direction of the closure head 1, in the area of which the two-armed extractor 2 is spring-loaded.
  • the nose of the extractor 2 engages in an assigned driver groove 6 in the area of the locking wedge 5.
  • the reference number 7 shows the driving nose of the extractor 2, which engages in the driving groove 6 of the locking wedge 5.
  • closure lugs 11 are arranged in a plane, which are directed axially forward and at a mutual distance from one another and which form gaps evenly distributed between them on the circumference. These breech lugs 11 lock the breech head 1 in the barrel receiver 30 (monoblock) and transfer the load of the gas charge to the breech.
  • Figure 11 shows the top view of the unlocked locking head 1 in the receiving sleeve 8, and the Figures 12 to 15 show the unlocked position. It can be seen that the actuating surface 19 is raised against the spring force of the locking springs 20, according to Figure 22 the locking springs 20 are arranged in pairs in a preferred embodiment.
