Definitions
- the present invention relates to a repeating device for a repeating rifle, which can be designed both as a rifle (rifled barrel) and as a shotgun (smooth barrel).
- the reloading process for weapons with cartridge ammunition is now carried out either automatically by the energy generated when firing in the form of recoil or gas pressure, or manually by muscle power.
- the manual repeating process considered here i.e. removing the empty cartridge case and feeding in a new cartridge as well as closing the barrel behind the cartridge chamber, is usually carried out by a bolt with a bolt body, an operating lever (chamber stem), a handle on the forearm, a rotating lower lever and, rarely, by the handle that encloses the firing hand.
- grip repeating rifles Such repeating rifles, hereinafter referred to as grip repeating rifles, whose repeating process is carried out by a sliding movement parallel or essentially parallel to the barrel axis by means of a handle located behind the trigger unit, have been known in individual examples or small series since the end of the 19th century, but have not yet been able to establish themselves.
- the main problem with industrially manufactured grip repeating rifles is a path provided by the distance between the force introduction point on the grip and the barrel axis, which when repeated in conjunction with the axially movable bolt in a This results in a tipping moment, which often causes a jerky repeating action or even jamming.
- This effect is further intensified by the stick-slip effect ("chattering effect", constant alternation between static and sliding friction) of the sliding handle and by any catch devices on the bolt for fixing it in the front end position.
- Another problem is the risk of injury to the repeating hand caused by the sliding handle by crushing the fingers or hand in the rear end position, which is also known as the open position.
- the front end position is analogously known as the closed position.
- the object of one embodiment of the present invention is therefore to create a repeating device with which a remedy for the aforementioned disadvantages can be provided and which allows grip repeating rifles to be used safely by all shooters.
- repeating should be ergonomic and easy to carry out with a high level of safety and reliability.
- the repeating process is carried out by pulling back and then pushing forward the repeating mechanism and consequently the bolt coupled to it.
- a tilting moment can be introduced into the repeating mechanism and the bolt, which can lead to the stick-slip effect described above. This effect is naturally more pronounced when the bolt is pushed forward than when it is pulled back.
- the guide element for example a compression spring of the grip repeating rifle according to the invention, stores the energy manually introduced into the bolt when it is opened for reloading a new cartridge and for pre-tensioning the bolt in the closed position.
- the bolt slides much more smoothly than in handle repeating rifles known from the state of the art due to the coaxial introduction of force when closing.
- the spring force of the compression spring can be selected so that the bolt is pushed forward and closed by the compression spring alone.
- the compression spring can be arranged in the handle repeating rifle so that the spring force acts parallel to the displacement path of the bolt. The torque introduced into the bolt can thus be kept low.
- Coupling elements such as a transmission piston, can be used to introduce the spring force into the bolt as centrally as possible, even though the guide element is arranged eccentrically.
- the spring force usually acts more evenly than the feed force that the shooter would introduce directly into the handle.
- the provision of a compression spring also helps to carry out the repeating process more reliably and to prevent the bolt from jamming. Since the stick-slip effect can be avoided in this way, the noise generated during the repeating process can also be kept lower.
- the first and second displacement axes typically run parallel to the firing direction.
- the first displacement axis is also referred to as the "barrel core” or “barrel centerline”.
- the spring force applied by the compression spring is introduced centrally or almost centrally into the bolt, so that either no torque at all ("lever arm free") or only a small, negligible torque acts on the bolt.
- the shooter can push the bolt forward very evenly and easily without the need for coupling links, as a result of which the repeating process can be carried out reliably.
- the bolt and the repeating device can be synchronized with one another by means of a coupling rod.
- the coupling rod By using the coupling rod, the bolt can be connected to the repeating device in such a way that the first displacement axis and the second displacement axis can also be at a greater distance from one another.
- the coupling rod is a relatively simple component that is inexpensive to provide. Additional coupling elements such as gears, racks or the like are not necessary.
- the distance can be dimensioned such that additional components of the grip repeating rifle can be arranged between the repeating device and the bolt, thereby achieving a compact design.
- the arrangement of the coupling rod can be chosen relatively freely, so that it can be arranged where it does not require any extensive design changes to the adjacent components.
- the trigger blade Due to the arrangement of the trigger blade in or on the repeating mechanism, the trigger blade is moved linearly together with the repeating mechanism during repeating. In particular, compared to the DE 197 35 737 A1 In the repeating rifle shown, the position of the trigger is more intuitive for the operator, which enables safe and reliable operation.
- the trigger blade or the interrupter mounted on it can only be engaged with the trigger bar in the closed position can come into contact with each other in such a way that the striking piece can be triggered.
- the sliding bushings can be made of plastic and slide along the guide rods with little friction, which is why the repeating device can be moved easily along the linear guide.
- the guide rods preferably have a circular cross-section, which makes their manufacture and assembly simple. In addition, manufacturing inaccuracies in the guide rods can be corrected relatively easily with appropriate post-processing compared to other cross-sections.
- the repeating device may be advisable for the repeating device to have a protective plate which encloses the linear guide.
- the protective plate can, for example, be attached to the handle above the grip and is therefore moved during the repeating process. As a result, the risk of injury due to crushing of the hand is reduced.
- an additional spring-loaded slide in the magazine is used to control the Slide stop inserted, which is firmly connected to the magazine well.
- a further embodiment relates to a grip repeating rifle with a repeating process via a linear sliding movement of the handle enclosed by the trigger hand, also called a grip repeater, wherein the bolt is preloaded by a compression spring positioned behind it coaxially to the barrel axis and is held by this in the closed position.
- the sliding handle is mounted in two parallel, round guide rods.
- the sliding handle can have inserted plastic bushings, which in turn are in contact with the guide rods.
- a protective plate can be mounted on the top of the slide, which completely covers the stationary parts of the sliding device such as the guide rods in all positions during the repeating process.
- the magazine well can be modular, i.e. detachably connected to the weapon housing and thus replaceable.
- a bolt catch can prevent the bolt from leaving the rear, open position (open position) during the next repeating process without removing the empty magazine or inserting a full magazine.
- the repeating device can be secured in its end positions by one and the same locking element.
- the repeating slide can be blocked in its end positions by a locking element mounted in the housing.
- a locking element is used for both The same locking element is used for all end positions, which further increases safety.
- Figure 1A is an embodiment of a grip repeating rifle 10 according to the invention in a closed position and in Figure 1B shown in an open position.
- the grip repeating rifle 10 is in this case designed as a repeating rifle.
- the firing direction S is also marked.
- the grip repeating rifle 10 comprises a housing 12 to which a barrel 14 is attached, in particular by screwing.
- the repeating rifle 10 comprises a cartridge chamber 16 in which a cartridge 18 can be stored (neither in Figure 1A still in Figure 1B there is a cartridge 18 in the cartridge chamber 16).
- the cartridge chamber 16 is incorporated into the barrel and is partially surrounded by the housing 12 in the embodiment shown.
- the grip repeating rifle 10 is equipped with a bolt 20 which is mounted linearly in the housing 12 for unloading and loading the cartridge chamber 16, a hammer 22 which is mounted movably in the housing 12 and can be preloaded, a firing pin 24 which is mounted axially in the bolt 20 and can be preloaded by a spring for firing the cartridge 18, and a rotatable trigger blade 26 with which the preloaded hammer 22 can be actuated.
- a trigger rod 28 which is mounted rotatably in the housing 12 is arranged between the trigger blade 26 and the hammer 22.
- the grip repeating rifle 10 has a slide stop 30 which is rotatably mounted in the housing 12 between a locking position and an unlocking position. In the locking position, the slide 20 cannot be moved linearly, while in the unlocking position the slide stop 30 releases the slide 20 for linear movement.
- the grip repeating rifle 10 has a repeating device 32 for unloading and loading the cartridge chamber 16 and for cocking the hammer 22.
- the repeating device 32 is mounted on a linear guide 34 so that it can be moved linearly, the linear guide 34 being fastened to the housing 12.
- a protective plate 36 is fastened to the repeating device 32, which protects the linear guide 34 at least in the Figure 1A shown open position and protects the shooter's hand from crushing.
- the trigger blade 26 is arranged on the repeating device 32 and is rotatably mounted there and can therefore only be moved linearly with the same. Furthermore, a handle 38 is attached to the repeating device 32.
- the housing 12 forms a magazine slot 40 into which a top-filled magazine 42 that can be filled with cartridges 18 can be inserted.
- the bolt 20 is arranged above the hammer 22 and the trigger rod 28 so as to be linearly displaceable along a first displacement axis A1.
- the repeating device 32 is linearly displaceable along a second displacement axis A2 defined by the linear guide 34.
- the first displacement axis A1 and the second displacement axis A2 run parallel to one another and spaced apart from one another.
- the hammer 22 is mounted in the housing 12 so as to be rotatable about an axis of rotation D, wherein the axis of rotation D runs between the first displacement axis A1 and the second displacement axis A2 and perpendicular thereto.
- the bolt 20 and the repeating device 32 are connected to one another by means of a coupling rod 44, whereby the movement of the repeating device 32 is transmitted to the bolt 20.
- a compression spring 46 is provided, which is arranged coaxially to the closure 20 and to the first displacement axis A1 and interacts with the closure 20, wherein between the compression spring 46 and the closure 20 a transmission piston 47 is also arranged coaxially to the closure 20.
- the compression spring 46 is arranged at the rear end of the housing 12 as seen in the firing direction and extends into a Rifle butt 49. The compression spring 46 closes the bolt 20 in the Figure 1A shown position.
- Figure 2A shows an isolated side view of the repeating device 32 and Figure 2B a sectional view along the Figure 2A defined cutting plane AA.
- the linear guide 34 comprises a total of two guide rods 48.
- Two sliding bushings 50 in this case two plastic bushings, are inserted into the repeating device 32, which come into contact with the guide rods 48 and which can be moved along the guide rods 48.
- the Grip Repeater Rifle 10 can be operated in the following way: As mentioned, the Repeater Rifle 10 is in Figure 1A in the closed position, in which the bolt 20 and the repeating device 32 are in a front end position with respect to the firing direction S.
- the compression spring 46 is slightly compressed.
- the shooter can move the repeating device 32 to a rear end position by pulling on the handle 38. To do this, the repeating device 32 is moved on the linear guide 34 along the second displacement axis A2. Since, as mentioned, the coupling rod 44 connects the repeating device 32 to the bolt 20, the bolt 20 is also moved along the first displacement axis A1 to the rear end position. The shooter must move the repeating device 32 against the spring force of the compression spring 46, whereby the compression spring 46 is compressed. When moving to the rear end position, the empty cartridge case is pulled out of the cartridge chamber 16 and ejected from the housing 12 through an ejection window (not shown here).
- the firing of the hammer 22 is only possible when the bolt 20 and thus also the repeating device 32 are in the closed position. To achieve this, there are very small contact surfaces on the trigger rod 28 and on the trigger blade 26, or the interrupter 52 located on it, which are separated after the bolt 20 has been moved by just a few millimeters, when the bolt head is still safely in the closed position due to the dead travel. This reliably prevents the hammer 22 from being unlocked when the bolt 20 is open.
- a locking element 54 in the form of a multi-locking cross shaft is mounted in the housing 12, which, in addition to securing the trigger rod 28, also secures the repeating device 32 in the end positions and which, in an additional disassembly position, also blocks the trigger rod 28.
