Definitions
- Ejection device for a firearm and weapon housing and firearm with an ejector
- the invention relates to an ejection device for a firearm comprising a discharge main body with an ejection element arranged thereon such that the ejection element protrudes after mounting the ejection device on the weapon housing of the firearm in the path of movement in the weapon housing longitudinally movably guided, forward and backward closing device, an abutment for the sleeve bottom one of the returning closure device from the cartridge chamber withdrawn cartridge case forms and after active engagement with the sleeve bottom ejects the cartridge case from the weapon housing and / or ejects
- the invention also relates to a weapon housing and a firearm, each of which is equipped with such an ejection device.
- position designations such as “top”, “bottom”, “front”, “rear”, etc. always refer to the view of a shooter who keeps the gun in normal firing position with horizontal axis of the soul.
- Ejectors are known in different designs and have the task of ejecting or ejecting a cartridge case from a firearm, which has been pulled out of the cartridge chamber of the firearm immediately before by a arranged on a closure device extractor.
- the sequence of operation when firing a cartridge and subsequent ejection of the empty cartridge case is known per se and can be simplified briefly as follows: For firing initially introduces a closure device, in particular a closure head, a cartridge from a cartridge feeder into the chamber of a firearm. The operation of a trigger mechanism releases a firing pin, which then strikes the bottom of the cartridge and ignites there a propellant charge, so that a projectile is fired from the cartridge case through a pipe.
- the released during firing process forces or gases are used to put the closure back into a backward motion.
- the discharged shot gases drive the gas via a throttle linkage
- At least one cartridge extractor is provided on the closure device, for example on the closure head. This surrounds the empty cartridge case at the edge of the closure device
- the aforementioned generic type ejection device is known from DE 10 2010 009 488 B3 and is used for example in the machine gun HK121 the applicant.

- One after firing Recirculating bolt head pulls a cartridge out of the cartridge with an extractor
- this construction with rocker arm causes a relatively weak ejector spring, as the kinematically unstable rocker arm does not allow a strong return spring, but only a relatively weak, pure buffer spring.
- DE 1 015 724 shows an ejector for automatic firearms.
- a sprung mounted ejector slide is provided in the closure head.
- Lock return hits the ejector slide on a spring-mounted
- pivotable mass that extends the ejector slide forward out of the closure and thereby encounters the bottom of the cartridge.

- the buffering retards the impact energy, slows down the tube rotation, and causes a backlash of the buffered ejection main body and a total of one Harmonization of the entire ejection process. This results in softer engagement of the ejection device with the cartridge case in a first phase of the ejection operation, with the case bottom stop abutting the ejector main body, allowing a controlled homogeneous initial tilting movement of the cartridge case. Since the cartridge case is held downwardly and / or laterally by the extractor and ejected from the top of the ejector, this causes the cartridge case to rotate. To

- the ejection main body 5 approaches the guide and accommodating sleeve 9b.
- This structure illustrated here for the right-hand housing shell 23 (FIG. 7) is mirrored for the opposite left-here partially concealed-housing shell 25.
- FIGS. 5 to 9 illustrate the functional sequence of the invention
- the closure device here comprises a closure carrier and a closure head 71, wherein the extractor 69 is arranged on the closure head 71.
- the extractor 69 engages under the cartridge case 59 on the sleeve bottom 61 and pulls it out during the return of the closure device to the rear out of the chamber (not shown) out.
- the ejection element 46 protrudes into the longitudinally extending groove 77 of the
- Fig. 5 the lock carrier and the lock head 71 move to firing with the extended cartridge case 59 to the rear.
- the extractor 69 is movably supported by a spring-loaded pin 73 about a pivot axis 75.
- Closure device or the closure head 71 is a firing pin 79 mounted longitudinally movably in a firing pin 81.
- a firing pin 79 mounted longitudinally movably in a firing pin 81.
- the ejection element 46 is the
- Fig. 6 shows the impact of the sleeve bottom 61 on the ejection element 46 and there in the recess 47 at the stop and guide surface 49.
- the shutter performs at its return - as described above - no rectilinear motion, but vibrates due to acting on him Gas forces and evades sideways, up and / or down.
- the abutment and guide surfaces 49 and 51 therefore guide the cartridge case 59 in the recess 47 and thereby improve the repeatability of the system of the sleeve bottom 69 in the recess 47th
- the ejection main body 5 runs against the restoring force of the springs 7a, b a short distance within the housing shells 23, 25 back.
- the springs 7a, b buffer the force peaks completely, which act on the ejection device 1 and the extractor 69. This slows down the ejection movement or the speed of the
- FIG. 7 Cartridge sleeve 59 in the first ejection phase.
- Figs. 7 and 8 the ejection of the ejection device 1 is shown pictorially.
- the ejector 1 is compared to Fig. 6 already moved further back towards the shaft and has compressed the springs 7a, b for buffering the force peaks.
- the closure head 71 continues to run backwards with the closure carrier.
- the spring package to be compressed is designed so that the reflected ejection main body (5) on the compressed Fedem 7a, b turns and not on
- the extractor 69 acts as an abutment that holds the sleeve bottom 61 at its lower edge.
- Fig. 7 also shows a second sectional plane through the receiving and guide sleeve 9a, b, in which the compression of the spring 7a is shown.
- the ejection element 46 engages with its stop and guide surfaces 49 and 51 at the upper end of the sleeve bottom
- the ejection main body 5 moves forward again in the second ejection phase counter to the direction of movement of the closure device and the ejection element 46 pushes the sleeve bottom 61 of the cartridge case 59 further forward.
- the cartridge case 59 further tilts down, the extractor 69 with a rear, the sleeve bottom opposite stop edge, the bolt 73 against a spring 74 pushes back.
- the extractor 69 pivots about his
- Pivot axis 75 to release the cartridge case 59.
- the cartridge case 59 is subsequently ejected downwardly through a cartridge ejection window formed between the housing shells 23 and 25.
- Fig. 9 shows the ejection device 1 after the ejection process in its preloaded mounting position in which the rear end of the leg 45 a from the rear end of the
- Recess 27a and from the front end of the receiving and guiding sleeve 9a is further spaced.
- the shutter is in a rearward position and has accumulated on shutter springs, not shown, or a buffer mechanism which, in a known manner, buffers the forces of rearward movement of the shutter.
- the extractor 69 is pivoted about the spring force of the spring 74 about the pivot axis 75 back and abuts the closure head 71.
- the closure device can introduce a new cartridge in the chamber during the flow in a known manner, so that a new firing is possible.
