Definitions
- the invention relates to a cartridge ejection arrangement with at least two cartridge extractor claws which are resiliently attached to a movable closure or closure head and which are preferably opposite one another (preamble of claim 1).
- Positional designations such as “above” or “vertical”, which are used here, refer to the weapon in the position of use, to which the said arrangement belongs.
- the shot direction runs horizontally “forwards”.
- a handgun especially a self-loading weapon, with a barrel and a breech that moves backwards and forwards along the axis of the soul (central axis of the barrel) from the rear end of the barrel generally has a cartridge ejection arrangement with an extractor claw and one Ejector on.
- the extractor claw engages around the edge or half-rim of the cartridge or engages in its bottom circumferential groove.
- the ejector sits, in relation to the axis of the soul, approximately opposite the claw, so that the edge of the cartridge bottom runs against it.
- the ejector is referred to here as stationary. This is understood here to mean that it is either firmly attached to the weapon or its housing or that it is movably mounted in the breech or breech head and at the end of its return runs up against a weapon-resistant resistance.
- the cartridge or cartridge case is ejected across the core axis.
- the extractor claw sits on the side towards which the cartridge or cartridge case is ejected.
- the ejector sits on the opposite side.
- the extractor claw sits fully in the groove when it is pulled out with a complementary holding surface.
- the cartridge or its sleeve can therefore only be released from this claw when it is tilted. This ensures reliable removal of the cartridge case.
- this hold is essentially only ensured by a force fit.
- a correspondingly strong spring then loads the puller claw to enable reliable pulling out.
- Fig. 2 of this document shows a longitudinal groove in the closure, which is located near one of the claws and could accommodate the ejector.
- Extracting shotgun cartridges for example of caliber 12 or 10
- caliber 12 or 10 is often problematic, particularly with very long cartridge cases and in self-loading weapons, because the fast-opening closure takes the extractor claws with them can then slide off the round rim of the cartridge edge.
- the double pull-out claw which is known from the publication mentioned, could perhaps remedy this. Even with extremely large cartridges that have a disproportionately small rim (fluorescent, tear gas or shot cartridges of caliber 4 (26.5 mm), grenade cartridges (4 cm) or the like), the double extractor claw could be advantageous.
- the cartridge can be ejected everywhere except towards the reloading device. If, for example, a harness sitting above the weapon is used, it can be ejected to the right or left, but also downwards, depending on where a sleeve shaft or sleeve bag can be attached.
- the object of the invention is to provide an improved cartridge ejection arrangement.
- at least one of the disadvantages outlined above is to be at least partially remedied and an arrangement of the type mentioned at the outset is preferably to be created, the ejection direction of which can be changed.
- the arrangement mentioned at the outset be further developed in that at least one stationary ejector can be assigned to one or each of the cartridge extractor claws in such a way that the cartridge or cartridge case is pulled out from a cartridge chamber by all cartridge extractor claws when the shutter or breech head retracts and, when it has come free from the cartridge chamber, swivels around the cartridge extractor claw and is thereby ejected towards its side to which no ejector is assigned (claim 1).
- each of the extractor claws is only able to hold the cartridge or cartridge case in the position in which it is pulled out to a limited extent.
- the use of multiple extractor claws also has advantages, especially with the cartridges mentioned above. If an ejector is now assigned to all extractor claws, except those on whose side the ejection is to take place, then the ejection can take place in any direction to which an extractor is assigned.
- the ejector now has two ejector projections, which are arranged on either side of one of the two cartridge ejector claws and run in the longitudinal grooves of the breech or breech head, which in the
- Buttocks open on both sides of the cartridge extractor claw (claim 3), then an arrangement is created that pulls out even difficult cartridges and cartridge cases perfectly, and can be converted from right to left ejection and vice versa with the simplest of means.
- Usual cartridge extractor claws have a hook-like end with a surface facing the impact floor, which grips around a cartridge edge. According to a further embodiment of the invention, it is proposed that when the hook-like ends encompass a cartridge rim, the surfaces of which form an acute angle to a plane parallel to the push floor, so that they move away from the front of the push floor towards the front (claim 4) ,
- This acute angle z is preferably between 0 ° and 15 ° (claim 5).
- the invention preferably uses a flat surface that sits on the edge. It is therefore possible to use cartridges of the most varied of construction types, including cartridges whose edge forms a surface that faces away from the butt plate and is parallel to it. Such an edge can be present in cartridge cases for special cartridges, for example light cartridges. Such cartridge cases are made by turning or by counter-extrusion.
- the arrangement according to the invention can be used for handguns of all kinds. It is particularly advantageous for large-caliber cartridges. It is particularly preferred, for example, that it be assigned to a shotgun (Claim 6), in particular a repeating or self-loading shotgun.
- a shotgun (Claim 6), in particular a repeating or self-loading shotgun.
- the structural diversity and mutual deviation of cartridges for one and the same caliber is particularly large, on the other hand the need to convert a weapon for right-handed shooters to one for left-handed shooters is particularly great.
- Such a weapon is not a personal weapon like a rapid-fire rifle that can accompany a soldier during practically his entire service, but is often only issued for special missions.
- wafers with a caliber of more than 15 mm are not included.
- FIG. 1 is an oblique view of a shutter of a self-loading shotgun, which is equipped with the arrangement according to the invention
- Fig. 3 is a view of an extractor claw
- Fig. 4 is a partial view of an ejector, seen from the front or the back.
- Fig. 1 shows a locking head 1 which is movable along two guide rods 3.
- This closure has a butt plate 5, on either side of which an extractor claw 7 is attached.
- the extractor claw 7 is shown enlarged in FIG. 3. It is stamped out of sheet metal, for example, and has an overall approximately T-shaped contour, the central shaft of which has a bore 9 at the end.
- a rear leg 11 and a front leg 13 extend transversely from the middle shaft at its other end.
- the rear leg 11 carries at its free end an angled nozzle 15, which is intended for engagement in a spiral compression spring (not shown).
- the front Schenekl 13 carries at its free end the actual claw 17, which has a surface facing the middle shaft 19, which extends at an acute angle to the extension of the central shaft, and thus also at an acute angle to the butt plate 5 (FIG. 2).
- Extractor claws 7 can each be pivoted about an axis, for example in the form of a retaining pin 21, which in each case passes through the bore 9.
- the closure 1 has on both sides a longitudinal web 25, on the outside of which the corresponding extractor claw 7 is attached.
- Each longitudinal web 25 has an upper and a lower edge which extend into the butt plate 5.
- Fig. 2 the closure of Fig. 1 is shown in plan view.
- the two claws 7 sit on both sides of a cartridge 23.
- An ejector 27 sits behind the closure 1 in the area of its return. This ejector is shown broken off and seen from above.
- the ejector 27 has a U-shaped cross section.
- the closure 1 runs back, then one of the longitudinal webs 25 runs through the ejector 27.
- the two U-legs of this ejector 27 overlap and underlap the corresponding longitudinal web 25 and reach with their ends into the butt plate 5.
- the ends of these legs are designated by 29 in FIG.
- the cartridge or cartridge case 23 Since the cartridge or cartridge case 23 is held on the closure 1 by means of the extractor claws 7 and taken with it, it runs back with the closure 1.
- the push bottom 5 arrives at the ejector 27, the bottom of the cartridge 23 runs on its ends 29 and is against the there (right) extractor claw 7 pressed. Because of the
- the pusher 27 can be inserted into a longitudinal or transverse groove in the weapon housing. A component of the weapon or a pen can hold the ejector in this position.
