Definitions

  • the invention relates to a weapon with case ejection, in particular a carbine, according to the preamble of claim 1.
  • the case can be moved backwards from the actual chamber of the breech with the retracting breech, in order to then move it to a suitable place in a mostly
  • the so-called mechanism for ejecting the case to ensure that the ejection window provided on the side of the weapon housing is suitably applied with a transverse force that it reliably emerges from the window.
  • the breechblock advances under the action of the return spring, the next cartridge can then be pushed from the magazine into the chamber.
  • a claw mounted in the closure the pull-out claw
  • the pull-out claw is mostly used to safely move the sleeve with the closure, which encompasses the sleeve base, which almost always has a flanging or a similar change in the diameter in the base area, and thus for safe entrainment of the Case from the chamber of the barrel.
  • the part of the closure adjacent to the case base, in which the pull-out claw is arranged, is often referred to as the closure head.
  • the application of the transverse force which is mostly sideways, but in a few cases upwards, is mostly brought about by the fact that the case base runs eccentrically when it moves backwards onto a part connected to the frame of the weapon, usually called the ejector the combination of the action of the claw, the inertia forces and the eccentric impact on the component connected to the frame (ejector, ejector bolt) results in a corresponding moment or a corresponding transverse loading and the sleeve is ejected from the window.
  • the ejector the combination of the action of the claw, the inertia forces and the eccentric impact on the component connected to the frame (ejector, ejector bolt) results in a corresponding moment or a corresponding transverse loading and the sleeve is ejected from the window.
  • the invention has the aim and the task of creating an operationally reliable ejection mechanism that meets the conditions mentioned and, in addition to the reliable functioning, is also space-saving, which is simple and therefore inexpensive and unproblematic in maintenance.
  • it is an object to be achieved, at least in one embodiment of the invention, to trigger the ejection of a fired case or a non-fired cartridge at a defined point in time and / or at a defined position in a positively controlled manner.
  • the ejector pin is movably supported within the breechblock head parallel to the direction of movement of the breechblock head; it is under the action of a bolt spring, which pushes it backwards away from the case base; it acts indirectly with the housing stop, namely via one in the slide (also Called bolt carrier), in which the bolt head is movably guided, together rotatably mounted ejector lever.
  • the locking unit as a whole can be moved further backwards, in the direction of the end stop, by the explosion gases or the inertia, and thus the paths and the inertia forces can be moved of the breechblock and breechblock head can be determined and determined independently of the activation positions and the forces that occur for the ejection of the case, which was previously not possible.
  • the design of the ejector lever also contributes to this, due to the existence of which the lever arm from the housing stop to the axis of rotation is longer than the lever arm from contact with the ejector pin to the axis of rotation, so that its movement path is smaller, but the forces that occur are greater than those of the ejector lever on the housing stop .
  • a spring loading by means of an ejector spring can secure the return of the ejector lever to the normal standby position (rest position) when the closure and the closure head are moved forward again by the closing spring and have reached the position in which the housing stop (functional edge) no longer prevents rotation.
  • an ejector spring can also ensure that the ejector pin also returns to the standby position under the action of its pin spring.
  • the two springs are preferably designed as helical springs that work under pressure, which ensures the longest possible service life for springs.
  • the springs can either be arranged with appropriate shoulders on it and its guide around it, but preferably lie in a spring chamber lying parallel to the guide hole of the firing pin, and act on at least one thickening (or also an extension or ejector wing) of the ejector, which also determines the two end positions of the ejector.
  • the ejector lever has a spring arm designed in such a way that it is under the action of a suitably arranged helical spring that works as a compression spring.
  • the arrangement and design of such a spring arm and the guidance and mounting of the spring depend on the structure of the bolt head and can easily be designed and dimensioned by a person skilled in the art with knowledge of the invention and the basic design of the weapon.
  • the ejector pin lies in the guide recess of the locking head over the largest area of its length and is thus protected as best as possible against all types of bending stress. It can therefore be built relatively robustly for the axial load that it naturally experiences without having to deal with disadvantages, without becoming too bulky.
  • the ejector pin has, at least on one side, radial wing-like extensions, also called ejector wings, which, in cooperation with a recess in the locking head provided for this purpose, represent an axial limitation of the movement.
  • the ejector pin has a radial widening or radial extensions or ejector wings at its rear end, whereby a larger impact surface is formed for the ejector lever.
  • the ejector lever can be made solid in the direction of its axis of rotation, there is usually enough space available in the slider, and it must be taken into account that the main stress occurs despite the design as a rotary lever only in the area between the contact with the housing stop ( Functional edge) and in contact with the ejector. There is a rotating-sliding movement on both contact surfaces.
  • the part of the ejector lever located in between can be made so large (thick) in the circumferential direction, without impairing its mode of operation or undue space requirements, that the forces that occur are transmitted over a sufficiently large cross-section.
  • the contact between the ejector lever and the housing sliding surface lying in the longitudinal direction parallel to the locking movement, thus also parallel to the barrel axis, which is adjacent to the functional edge or the functional cam, can be achieved by appropriate coordination of the surface hardness and a rounded design of the free end of the ejector lever and / or After a few attempts, the transition from the housing stop to the housing sliding surface must be designed in such a way that, on the one hand, the friction contributes to the slowing down of the breech and thus to the lowering of the rate of fire in automatic weapons, and, on the other hand, there is no need to worry about damage from the friction occurring. Even if the functional edge is then a function rounding, the term functional edge is used in the following and in the claims.

  • FIG. 2 shows a perspective view of a slider 18 with a locking head 19 which has a recess 22 for an ejector 21 according to the invention, also called an ejector pin, and a central bore for a firing pin 25.
  • the ejector 21 has two radially protruding ejector wings 23 which are axially spaced from one another, which on the one hand determine its angular position and on the other hand interact with an ejector spring 24 designed as a helical spring.
  • the ejector spring 24 lies with its front end facing the barrel on a detent in the recess 22, with its other, rear end on one of the ejector wings 23 and urges it, and thus the ejector 21, from the impact base 42 (Fig. 4d). of the locking head 19 away to the rear, into its rest position.
  • Matching spring plates can be provided, and, as shown, the firing pin 25 can be arranged in the core of the ejector spring, as a result of which dynamic stabilization
  • the ejector wings 23 and the interacting abutment surfaces of the recesses 22 in the locking head 19 are geometrically coordinated with the ejector spring 24 so that the axial end positions of the ejector are not determined by the spring, whose dynamic load thus remains limited.
  • the ejector 21 protrudes with its rear end axially from the Closure head 19 and forms an abutment surface 43, which, as explained in more detail below, lies in the path of movement of an ejector lever 28.
  • a closing spring unit 26 which, after the slide 18 has returned, brings it back into its front, ready-to-shoot position, and the upper housing, the upper 4, symbolically represented as a prismatic profile, with guides 6 for the slider 18, there also purely schematically, because it does not belong to the invention, indicated by lateral, groove-shaped recesses (slots).
  • Figs. 3a-3c show three variants of an ejector lever 28 according to the invention in its rest position: In all cases it is mounted in the slide 18 in such a way that in its rest position it assumes a position that is essentially perpendicular to the barrel axis 38 and about an axis of rotation 32 that is normal to the weapon means plane 44 runs, is mounted pivotably or rotatably between two end positions.
  • a stop 33 on the ejector lever 28, in conjunction with a counter surface 40 on the slide 18, defines the first of these positions, the rest position. In the illustration of FIGS. 3a-3c, this corresponds to the prevention of any further rotation of the ejector lever 28 in the counterclockwise direction.
  • the second end position of the ejector lever 28, known as the working position, is reached when it meets with an ejector surface 39 on its front side facing the locking head 19, an abutment surface 43 on the rear side facing away from the locking head 19 at the end of the ejector 21 and this up to has brought its stop in the foremost position (Fig. 4d).
  • Remaining of the ejector lever 28 in the rest position can, but does not have to be, secured by a return device 31 comprising at least one spring element, as will be explained further below.
  • the ejector lever is formed with one leg with the leg 29, the ejector surface 39 can be designed cambered, which is the case with the sliding-rolling Contacting with the abutment surface 43 is advantageous; the Hertzian pressure, which is increased by the crown, can be well controlled by surface hardening.
  • the stop for preventing further rotation of the ejector lever 28 is formed by the geometry of the ejector 21 and its movement limitation in the locking head by the ejector wings 23.
  • the ejector lever 28 is provided, in addition to the leg 29, with a lever arm 30 which, in the exemplary embodiment shown, lies opposite the leg and rests with a projection or stop 33 on an end face 40 of the slider 18.
  • the stop 33 can also be formed by the lever arm 30 itself, which, for example, has a recess or also a flattening matched to the end face 40.
  • the end face 40 is arranged in the direction of the running axis 38 in such a way that the lever arm 30 can be deflected slightly, i.e. a few degrees, preferably 5 to 30 °, relative to a normal to the running axis 38 forwards before the stop 33 on the end face 40 strikes.
  • Such an arrangement of the end face 40 can avoid an “overshoot” and thus a possible blocking of the ejector lever 28 of the slider 18 during the return movement.
  • Fig. 3c provides a restoring device 31 for the ejector lever 28, in which the end face 40 is not fixedly arranged on the slider 18, but can deflect against the force of a spring element.
  • the ejector lever 28 When it hits the functional edge (FIG. 4), the ejector lever 28 is deflected away from the resetting device 31 (in FIG. 3c in a clockwise direction) - that is, towards the “rear”.
  • the resetting device 31 in FIG. 3c in a clockwise direction
  • an "overshoot" - that is, an excessive deflection of the leg 29 or the ejector lever 28 to the rear - can be avoided and the movement can be cushioned.
  • the arrangement of the spring is shown as a compression spring which acts on the arm 30 in the manner described. If space permits, a tension spring acting on the leg 29 can be provided instead of this compression spring, or a torsion spring arranged around the axis of rotation 32, which requires only a small amount of space, moreover at a favorable location in the slide piece 18.
  • the decisive factor is the mode of action, according to which a blocking of the ejection uplift ice 28 at the functional edge 35 when the slide 18 is running back can be efficiently avoided.
  • the ejector lever 28 is designed so that its leg 29 has a length at which, when it is in the rest position, its path of movement when moving with the slider 18 with one in the lower housing, lower 10, or there functional edge 35 or functional cam 35 'connected to it collides.
  • a slight deflection of the leg 29 to the rear by a few degrees, deviating from the normal to the running axis 38, is thus possible, but it is advantageous to avoid an "overshoot" or excessive deflection of the leg 29 to the rear by, for example, a stop accordingly the description of FIG. 3b or FIG. 3c is used, as a result of which blocking of the slider 18 at the functional edge 35 can be avoided.
  • This functional edge 35 in Figs. 4a-4d, has the shape of a step or corner in a section parallel to the weapon center plane with a stop surface running normal to the barrel axis 38 and a sliding surface running parallel to the barrel axis, as can be seen clearly from FIGS. 4a-4d. For the sake of clarity, it shows the ejection of a cartridge (that would be the case in the event of a failure in ignition and dog-like movement of the slide) and not the ejection of a case.
  • the functional cam 35 ' is rotatably mounted in the lower 10 between two end positions and also has a stop surface and a sliding surface, by means of which a functional edge is formed.
  • the sliding surface runs, seen in section parallel to the weapon means plane 44, from the stop surface at an angle away from the barrel axis, up to a distance that no longer protrudes into the movement path of the ejector lever in its rest position.
  • the cam 35 ' is urged with its functional edge into the movement path of the leg 29 by a spring and rotates it or the ejector lever 28 completely analogously to the functional edge.
  • the area of the lower 10 behind the function cam is designed in such a way that there is no contact between the ejector lever 28 and the lower 10. The slight rotation of the cam under the action of the advancing ejector lever does not bring any noticeable axial Change of position of the stop surface of the cam with it, it is thus to be regarded as weapon-proof.
  • the ejector lever thus moves into the rest position, possibly under the action of its reset device 31.
  • the cam can deflect against the force of the cam spring when it hits the ejector lever 28, which is in the rest position.
  • the reset device has the task of limiting the "overshoot" of the ejector lever.
  • the first force component acts through the ejector spring (24) on the leg (29).
  • a second force component acts through the resetting unit (31), whereby the leg is correctly positioned in FIG. 3c by the force on the stop (33).
  • a mechanical stop (40) in FIG. 3b) or also FIG. 5 can be used.
  • the leg 29 of the ejector lever 28 is ultimately positioned in an angular position on the slider 18 which, if a functional edge 35 is provided, depends on the position of the sliding surface 45 and the shape and size of the leg 29, called the ejection position.
  • the ejector wing 23 determines the “absolute” end position of the ejector and thus of the adjacent ejector lever when it rests on the end of its associated recess. For reasons of tolerance, its end position must be rotated further than when sliding on the sliding surface, otherwise it will stick.
  • This ejection position is at least as far away from the rest position as the sliding position, which is given by the sliding surface, is thus usually only reached for a short time. If a function cam 35 'is provided, in which the leg 29 returns to its rest position without contacting a sliding surface, the ejection position is only assumed for a short time.
  • the slider 18 can continue to run in the direction of its end stop due to its kinetic energy and possibly still active propellant gases, with the ejector 21 and thereby the ejector lever 28 being urged towards its rest position in the case of a functional edge 35 by the bias of the pin spring, it rests on the sliding surface and a frictional force can be applied.
  • the embodiment of the ejector mechanism according to the invention leads to a positively controlled triggering of the sleeve or cartridge ejection when the functional edge 35 is reached; the path of the ejector 21 itself has to be taken into account or not, depending on the desired accuracy; that is, at a defined point in time and / or at a defined position.
  • the return speed of the locking unit 7 is reduced by the friction between the ejector lever 28, more precisely its leg 29, and the sliding surface 45 of the functional edge 35 or functional cam 35 'arranged in the lower housing 10, whereby inter alia. the rate of fire when firing bursts or in continuous fire operation can be influenced, in particular reduced.
  • the ejector lever 28 has at least one first extension 48 in the area of its axis of rotation 32, which is provided for mounting in a corresponding receptacle of the slider 18.
  • This first extension 48 can preferably be bolt-shaped be formed, wherein in the radial direction around the axis of rotation 32 a projection can be formed at least partially in the circumferential direction, as can be seen well in Fig. 5 in conjunction with Fig. 2:
  • the first extension 48 or the projection on the extension can be flattened in this way be so that the ejector lever 28 can be inserted into the slider 18 or removed from it when it is rotated into the working position.
  • a possible shape of this type of this first extension 48 with a projection is particularly clear from the oblique view in FIG. 5c.
  • a flattening is provided on the first extension and / or a projection that is not fully formed.
  • Such a flattening or such a projection can simultaneously serve as a stop 33, which interacts with an end face 40 of the slider 18 (FIG. 5a), analogous to the mode of operation of the embodiment with a lever arm 30 as described with reference to FIG. 3.
  • the ejector lever 28 is additionally guided or supported in the direction of the axis of rotation 32 on the slider 18 when activated and rotated in the direction of its working position, and twisting or inclined position of the ejector lever 28 can be efficiently avoided .
  • This favors the reliable triggering of the ejection and, moreover, the forces acting on the ejector lever 28 are well transferred into the slide piece 18.
  • the fatigue strength of the ejector lever 28 can be increased, since a bending stress at the point of rotation, that is to say about the axis of rotation 32, is reduced.
  • the ejector lever 28 can preferably be designed in one piece, for example as a milled part or metal injection moling (MIM), which means that the number of components for the closure unit 7 can remain low and yet it can be easily dismantled and maintained / cleaned .
  • MIM metal injection moling
  • the ejector lever 28 which, with respect to the axis of rotation 32 and along this, has two opposite radial extensions 48, 49, as shown in FIG. 5c. It is advantageous if the second extension 49 has a length that it at least temporarily ensures that it protrudes beyond the firing pin safety device 27 (FIGS. 7a-7c).
  • a head start, analog to the first extension 48 described above, can be provided under certain circumstances, but is not absolutely necessary for the advantages explained below.
  • the second extension 49 on the ejector lever 28 enables a particularly simple assembly of the locking unit 7, as can be seen from FIG. 5c in conjunction with FIGS. 7a-7c it can be seen directly: Since the ejector lever 28 only has to be inserted into the recess provided on the slider and the loss protection is carried out by means of the firing pin safety device 27 accommodated in the slider 18, the installation can be carried out in the simplest way.
  • the second extension 49 can be used as a driver for the closing spring unit 26, whereby a simultaneous and very simple removal of the lock 7 together with the closing spring 26 from the upper 4 is made possible.
  • the firing pin safety 27 is usually spring-loaded and is normally only deflected laterally by the hammer when the shot is fired.
  • the firing pin safety 27 is manually deflected to the side, whereby the second extension 49 of the ejecting lever 28 can be moved past the firing pin safety 27 unhindered and the ejecting lever 28 can be inserted into the recess provided in the slide 18.
  • additional securing elements of the ejector lever 28, such as pins, screws or the like can be dispensed with.
  • the ejector lever 28 is additionally prevented from relative movement during operation by the firing pin safety device 27 - apart from the intended rotation - which enables stable guidance and, at the same time, protection against loss.
  • the bolt-shaped projection of the first extension 48 or the entire extension of the ejector lever 28 can have a stop 33.
  • a stop 33 can, for example, be designed as a link-shaped or semicircular projection in order to interact with a corresponding stop 33 on the slider 18 (see Figs. 5a-5c)
  • Such a stop 33 on the slider 18 and on the extension can be produced relatively easily and reduces the required number of components while maintaining a high level of security.
  • the ejector lever 28 can have a second lever arm 30 which is formed from the axis of rotation 32 essentially opposite the leg 29. (see Fig.3b)
  • a stop 33 is to be provided on the second lever arm 30, which interacts with the slider 18 and limits the rotation of the leg 29 towards the rear.
  • the ejector lever 28 can be under the action of a spring element (part of the restoring device 31) which urges it in the direction of the inactive position, that is to say the rest position. (Fig.3c)
  • the functional edge 35 or a functional cam of the lower housing 10 is at least partially movable, whereby it acts rigidly with respect to the ejector lever 28 when the ejector lever 28 is actuated in the return movement of the slider 18 and afterwards in the forward movement can tip or rotate at the bottom. (Fig. 6)
  • This measure has the advantage that reliable triggering of the ejector mechanism can be decoupled from any friction losses caused by the ejector lever 28 on the lower housing 10.
  • FIG. 7a shows the ejector wings 23 in a side view, which are approximately in the middle of the longitudinal extent and at the rear end are provided. These interact with ejector recesses 22 on guide piece 18; in the exemplary embodiment shown, the rear recess is stunted to form an exemption.
  • An ejector spring 24 is provided coaxially outside the firing pin spring 25, see FIG. 7c in conjunction with FIG. 2.
  • a spring plate 47 with a sleeve can be inserted into this ejector spring 24 on both sides so that the two sleeves are directed towards one another.
  • the outer diameter of the sleeves is smaller than the inner diameter of the ejector spring 24, the inner diameter of the sleeves is larger than the outer diameter of the firing pin spring.
  • the overall length of the sleeves is limited at the top so that when the spring is compressed in the course of the ejection movement of the ejector 21, this movement is not hindered.
  • the ejector 21 interacts by means of a thickening 46 on its rear side with a spring plate 47 arranged on the ejector spring 24 and is thus pushed backwards into its rest position, which in turn is determined by ejector recesses 22 on the guide piece 18 in connection with the ejector wings 23.
  • the ejector spring 24 may or may not be pre-tensioned, depending on the requirements.
  • the two spring plates 47 are preferably identical, so that it is not necessary to pay attention to an orientation during assembly as well as during insertion (FIG. 2, reference number 24).
