CARABINER WITH CLAMPING SLIDE

Description

[0001] The invention relates to a carabiner with a cocking slide unit, according to the preamble of claim 1, and DE 102018001984 A1.

[0002] This document discloses a loading device for self-loading firearms. The loading device comprises a base body and, arranged thereon, one or more pivotable loading levers, which in one embodiment have an elongated hole. The elongated hole surrounds the bearing axis of the loading lever. The loading device is complex in design, and its assembly and / or disassembly is correspondingly complex.

[0003] Cocking slides are provided on carbines (rifles) to enable the weapon to be cocked manually. For example, if there is no cartridge in the bolt and a new magazine has been inserted, the bolt is pulled back using the cocking slide, which tensions the recoil spring. The forward movement draws the cartridge into the chamber and locks the bolt. When the recoil spring is cocked, these processes are usually carried out by the recoil spring. In certain cases, however, it may be necessary to move the cocking slide forward manually, for example to push the bolt forward in the event of a loading jam if the force of the recoil spring / recoil spring is not sufficient to close the bolt and allow the next shot to be fired.In many cases, a separate device is provided for the latter activity, which is referred to in professional circles as "forward assist", but it is desirable to have a cocking slide that enables both activities.

[0004] Furthermore, the cocking slide should be equally operable by both left- and right-handed users (ambidextrous), which is becoming increasingly important compared to the past. Another requirement is that the cocking slide be located in front of the slide (muzzle side), as otherwise it would be difficult to operate it when the weapon is at the ready. Cocking slides located behind the slide require the operator to operate the slide close to the face, which is cumbersome and, above all, results in poor arm positioning for the operator.

[0005] The cocking slide should also not participate in the normal movement of the slide and bolt, as this increases the mass of the moving parts and makes it necessary to provide stronger springs, thus ensuring a stronger force introduction through the gas drive, which in turn increases the overall forces acting, which makes the weapon as a whole more unstable, since it involves moving masses.

[0006] Finally, the cocking slide should also change the outer contour of the weapon as little as possible and, above all, should not have any protruding parts that could cause obstructions and problems, especially in the field.

[0007] Numerous proposals are known from the state of the art, the most important of which will be briefly discussed below, taking into account not only the following but all the English-language documents mentioned in the description: US 8,156,854 B2, US 9,109,848 B2, US 9,366,489 B1 US 8,899,138 B2, US 7,240,600 B1, US 8,561,517 B2, US 9,733,030 B2, is incorporated by reference into the content of the present application.

[0008] US 8,156,854 B2 discloses a carbine with a cocking lever which, in a first embodiment, can be mounted on a suitable mechanism either to the right or left of the barrel, whereby the conversion requires a complete disassembly of the weapon. For reasons of strength, a different cover or housing must also be provided during the conversion, since the handle of the cocking slide protrudes through a long, slot-shaped recess in the cover. In a variant according to Figs. 15ff, a symmetrical design with two cocking levers is provided. In both cases, the handle acts on the weapon's gas drive via a slide-like component, which is thus subjected to considerable pressure during recoil against at least the force of the recoil spring, if not also against the resistance of dirt and the like. Due to its length, this requires a significantly more robust design than without this additional function.In order to avoid the usual movement during normal firing of shots, the handle engages with a pin in a lateral recess of the casing of the gas drive only when it is rotated about an axis and is thus in the action position, which creates an unpleasant dynamic situation especially for such an action, which is usually carried out with great force, and, as Fig. 10 and 15 of the publication show in particular, is very susceptible to contamination.

[0009] Another solution is known from US Pat. No. 8,899,138 B2, in which the force is applied not to the gas actuator, but to a special extension in the breechblock. This makes the breechblock significantly more massive, with the disadvantages mentioned above. Here, too, the handle protrudes through the cover, and although one illustration suggests the possibility of providing the cover with two corresponding recesses to simplify the conversion, this is hardly feasible in practice for mechanical reasons.

[0010] DE 39 28 125 A1 discloses a foldable handle as the handle of a cocking lever and deals almost exclusively with this, which is important because it is a cocking lever that moves with the bolt.

[0011] There is therefore a need for a clamping slide that at least largely avoids the aforementioned disadvantages and exhibits the desired properties mentioned above at least to a high degree. The aim and object of the invention is to create such a clamping slide and, at the same time, to ensure the simplest possible handling and a minimal number of parts for the clamping slide unit.

[0012] According to the invention, these objectives are achieved by providing a cocking slide of the type mentioned above with the features specified in claim 1. In other words, at least one handle has an elongated hole that serves to receive and support a pivot pin. The handle can thus be pivoted within limits around the pivot pin between a rest position and a working position and can be used for both the retraction and advancement movements. According to the invention, the elongated hole further has a slotted opening.

[0013] Furthermore, the clamping slide unit may have the following additional features: The cocking slide has two handles mounted on a cocking slide body so as to be rotatable about pivot pins; the handles are urged into their rest position by at least one handle spring around the pivot pins; at least one handle has a slotted control surface which, when moved into the working position, deflects a control element fixedly arranged on the housing in order to release a displacement of the cocking slide body along the weapon's center plane; the control element is designed to be elastically deflectable between a locked position and a released position; the cocking slide body comprises a counter-extension for interacting with the handle, in particular a control surface formed on the handle and / or a deflection limiter; the cocking slide body is mounted on or in a slide arranged axially in front of the slide and movable in the axial direction; the cocking slide body is mounted so as to be displaceable in the slide normal to the weapon's center plane.the cocking slide body is held in the slide by a locking mechanism; the cocking slide body has a locking recess for interacting with the spring-loaded locking mechanism which is formed on the slide at least one handle has a recoil spring driver which is designed to protrude from the handle in such a way as to interact with the recoil spring unit in the working position and to temporarily grip it; upon contact between the slide and sliding piece, when the handle is actuated into the working position, the recoil spring driver engages in a recess in the recoil spring unit, for example in a casing of the recoil spring, which corresponds to a forward position; in the forwardmost position of the slide, the recoil spring driver is pivoted out of the recess in the recoil spring by returning the handle to the rest position.

[0014] Embodiments of the invention, particularly to facilitate the use, and in particular the advancement, of the clamping slide, are specified in subclaims. In essence, these are the following features: the orientation of the elongated holes for the pivot pins attached to the cocking slide body, i.e. the elongated hole direction, runs in the unfolded position, i.e. the working position of the handles, normal to the barrel axis or weapon center plane; when the respective handle is pushed forward in the working position, a section of its contour, preferably the control surface, lies against a contact area of ​​the cocking slide body and / or a counter extension and prevents it from folding into the rest position; the handle has a control surface which is curved in plan view and can be supported on the counter extension in the working position in the direction of the weapon center plane; the control surface has a ramp orA link shape which rises along the arc shape in order to cause a displacement of the control element fixed to the housing in the vertical direction when the handle is actuated into the working position; at least one handle has a hook which is designed to substantially surround the elongated hole and to extend to the slot opening.

[0015] The inventive arrangement of an elongated hole on the handle and its mounting around a pivot pin enables limited deflection between a rest position and a working position. The pivot pin can be mounted after sliding the handle onto the cocking slide body, or in a special embodiment with an open elongated hole, the pivot pin can also be formed integrally on the cocking slide body and assembly is achieved by sliding the handle on, as explained below. The deflection between the rest and working positions made possible in any case by the elongated hole also allows for limited displacement of the handle, which enables a temporary locking effect of the handle for advancing the recoil spring unit and / or for tool-free assembly of the handle.

[0016] In a preferred embodiment, the elongated hole has an elongated hole direction, which, in the resting position of the handle, is formed at an opening angle of 5° to 85°, preferably between 20° and 70°, relative to the weapon's center plane. This ensures good force transmission from the handle to the pivot pin and thus to the cocking slide body when the handle is actuated forward, i.e., when the bolt is manually closed.

[0017] Furthermore, it may be advantageous for the elongated hole to be perpendicular to the weapon's centerline when the handle is in the working position. This also allows for good force transmission to the cocking slide body when the handle is operated in the working position—regardless of the selected handle shape.

[0018] At least one handle spring is arranged on the cocking slide body to push the handle(s) into the rest position. The handle spring can be designed as a spiral, leaf, or preferably a bow spring, which also allows for somewhat more complex geometries and reduces the total number of required components. In particular, it is advantageous to arrange only one handle spring on the cocking slide body to preload both handles toward their rest position.

[0019] To interact with the grip, or a control surface formed thereon, it has proven advantageous to provide a counter-extension on the cocking slide body. This counter-extension can serve as a stop for a grip deflection limiter and / or as a central contact surface for the grip toward the weapon's centerline in the working position. This creates a locking effect for the grip in the working position, preventing lateral displacement of the grip.

[0020] In a further embodiment, a deflection limiter as mentioned above can be arranged on the handle in such a way that accidental "over-deflection" of the handle beyond the working position is blocked, since the deflection limiter is supported on the clamping slide body and / or the counter extension.

[0021] It has proven particularly advantageous if an imaginary extension of the deflection limiter runs parallel to the slotted hole direction of the respective handle. The deflection limiter can be designed as an extension or as a step. An imaginary axis through the deflection limiter, or along the step, is particularly preferably aligned with the slotted hole direction. This enables a very slim and thus weight-saving design.

[0022] To prevent the cocking slide unit from moving along with the slide with each shot, a control element can be provided on or in the upper receiver of the carbine. This control element can interact with the cocking slide body in such a way that it controls a locking effect or a release of the cocking slide unit parallel to the direction of travel. The actuation, i.e. the "control" of the control element, is carried out via a functionally complementary control surface on the grip. The control element can be pre-tensioned in the vertical direction as a lock by means of spring elements, or it can be integrally designed as an elastic control element, e.g., as a leaf spring. The control surface on the grip has a bevel, which deflects the control element vertically when the grip is rotated, thus enabling the cocking slide unit to be moved along the direction of travel.Such a combination of control surface and control element enables a significant reduction in components and relatively simple operation.

[0023] In order to further facilitate the operation and assembly of the handle, the invention also provides a slotted opening in the elongated hole, which allows the handle to be pushed over the pivot pins.

[0024] In a particularly preferred embodiment, the handle has a hook that extends around the elongated hole. This hook-shaped extension allows the handle spring to be displaced in the assembly position, thus increasing user-friendliness.

[0025] Furthermore, a locking recess can be provided on the cocking slide body, which, with a spring-loaded locking mechanism, enables automatic locking of the cocking slide body in the installed position in the slide. This allows the cocking slide body to be pushed sideways into a designated cocking slide receptacle in the slide, even when the weapon is otherwise assembled. This allows for very high operator comfort and very quick operation or assembly of the cocking slide unit.

[0026] The shape of the handles on the cocking slide body can be adapted to specific needs by a person skilled in the art, or even by the shooter, with knowledge of the present invention. In particular, the design of the actuating surfaces or the shape of the handles can be optimized in advance and relatively easily adapted to the specific situation by the shooter through the inventive (dis)assembly using a slotted hole partially open to the outside. This allows, for example, variation between handles of different lengths and shapes, or even a "blind handle" or a cover on one side, thereby achieving a high level of versatility for the cocking slide unit.

[0027] At this point, reference should be made to the content of the as yet unpublished European patent application EP19201448, in which a very similar principle for a clamping slide is disclosed.

[0028] The invention is explained in more detail below with reference to the drawing, which shows: the Fig. 1 an overview of a largely modular weapon; the Fig. 2 the installation situation of the clamping slide unit according to the invention in an oblique view; the Fig. 3 the cocking slide of the Fig. 2 an exploded view; the Fig. 4 an embodiment of a handle in view from above (a), the side (b), front (c), bottom (d), as well as diagonally from above (e) and below (f); the Figs. 5a and 5c the cocking slide of the Fig. 2 in a cross-section in different positions, as well as 5b and 5d corresponding oblique views; the Fig. 6 the clamping slide unit without slide in rest position (a), in working position (b) and in advance position (c); the Figs. 7a-da cocking slide body with handle spring and handles schematically in different positions in top view (top row of images) and bottom view (bottom row of images); the Figs. 8a-d a clamping slide in top view with examples of different handle variants, in rest position (top row of images) and working position (bottom row of images).

[0029] In the description and claims, the terms "front," "rear," "top," "bottom," and so on are used in their common sense and with reference to the object in its usual position of use. This means that the muzzle of the barrel of the weapon is "front," that the bolt or slide is moved "backward" by the explosion gases, etc. "Perpendicular to a direction" means a direction essentially rotated by 90° to it.

[0030] As from Fig. 1, a purely schematic representation in the weapon center plane 32 can be seen, a carbine when viewed from a correspondingly functional perspective and fully equipped has, for example, a barrel 1, a gas drive 2, a locking sleeve 3, an upper housing, also outside the USA mostly called upper 4, a carrier 5, which in turn has guides 6 for a bolt 7 and / or a cocking slide 8 and / or other functional elements, a fore-end 9, a lower housing, also called lower 10, which in turn comprises a magazine holder 11, a trigger device 12, a grip 13 and a slide stop device 14, a central locking 15, a magazine 16 and a stock 17.

[0031] Not all of these parts need to be present, and their design may vary slightly depending on the application, such as with hunting rifles. However, additional parts may also be added, such as mounting elements for rifle scopes, laser pointers, etc. Some of the components mentioned may also be inseparably integrated into a more complex component, such as the lower receiver or lower 10 in the illustrated case. Thus, the illustration represents only one example of a highly modular carbine.

[0032] The following illustration will present, by way of example, the structure and partial functions of several preferred embodiments of the clamping slide unit 8 according to the invention in sections.

[0033] Basic function of the clamping slide unit 8: The Fig. 2shows a schematic perspective view of an embodiment of a cocking slide unit 8 according to the invention. Only the components of the weapon that are essential for the cocking slide unit 8 are shown: a sliding piece 18, a recoil spring unit 31, and a cocking slide carriage, or slide 19 for short. This carriage has a cocking slide receptacle 27 in its front area. This cocking slide receptacle 27 can be completely open at the top or, as shown, partially delimited by a window in the transverse direction 38 and / or vertical direction 39. The cocking slide body 20 can thus be inserted laterally into the slide 19 in the transverse direction 38, normal to the weapon center plane 32, as indicated by the movement arrow.

[0034] As from Fig. 2As can be seen, an upper housing 4 is also indicated, in which the cocking slide unit 8 is arranged so as to be displaceable in or against the barrel direction 37. In this way, a cartridge can be loaded into the cartridge chamber of a barrel against the force of the recoil spring - in a manner known per se. The design and arrangement of the cocking slide unit 8 according to the invention also makes it possible to achieve the automatic folding of the handles 21 into the rest position, as well as a manual forward movement of the slide 18. The axis system used is shown for explanation with the axes or directions in the barrel direction 37, transverse direction 38 and vertical direction 39. Attention should already be drawn here to the slightly different design of the two cheeks or control surfaces 22 of the handles 21a,b in the mutually facing end region, which is explained further below.

[0035] In Fig. 3A schematic exploded view of the cocking slide unit 8 is shown, as well as an indicated closing spring unit 31. The cocking slide body 20 has two pivot pins 23a,b, also called "pins," along whose axes extend in the vertical direction 39. The pivot pins 23a,b can be mounted on the cocking slide body 20 or, preferably, can be formed integrally therewith. Two handles 21a,b, also called "handles," which are pivotably mounted about the pivot pins 23a,b, are shown opposite one another. Furthermore, a handle spring 24 is visible, which, in the illustrated embodiment, can be inserted into the cocking slide body 20 from below to urge the handles 21a,b toward their rest position.

[0036] Lateral installation of the clamping slide unit 8: From the overview of Fig. 3 with Fig. 2 and Fig. 5A locking mechanism 25 can be seen, which, after the cocking slide body 20 has been pushed in, automatically engages with the aid of a spring-loaded locking extension 26 into a locking recess 28 provided for this purpose on the cocking slide body 20. The locking extension 26 can be released when the upper 4 is open or when the carabiner is partially disassembled simply by actuating the locking mechanism 25, whereby the cocking slide body 20 can be pushed out of the slide 19 in the transverse direction 38. It is also possible to reverse the direction of action, for example by arranging the locking mechanism 25 with its spring-loaded locking extension 26 in the cocking slide body 20 and the corresponding locking recess 28 on the slide 19.

[0037] From the exploded view of Fig. 3 in conjunction with the Figures 2 , 5 and 6The position of the control element 29 mounted on the upper housing 4 can also be assigned. The mode of operation is explained in more detail below.

[0038] Form and function of an exemplary handle 21: The Fig. 4 shows a top view ( Fig. 4a ), a side view ( Fig. 4b ) or front ( Fig. 4c ), as well as a soffit ( Fig. 4d ). The Fig. 4e and Fig. 4fshow the handle 21 in a perspective view obliquely from above or below. The handle 21 can have a straight, curved, or as illustrated in the selected embodiment, a bent actuating element. The handle 21 has an elongated hole 36, which is shown in the following illustrations as a preferred embodiment by means of an elongated hole 36 partially open to the outside. The elongated hole 36 is opened laterally to the outside by means of a slotted opening 42 in one end region. The width of the slotted opening 42 essentially corresponds to the diameter of the pivot pin 23. The longitudinal extent of the elongated hole 36 is referred to as the elongated hole direction 33, see Fig. 8 . In Fig.4b and 4c a groove 34 is clearly visible, which allows the handle 21 to be pushed onto the clamping slide body 20 and thus a very small overall lateral extension of the clamping slide unit 8 in the transverse direction 38.

[0039] A closed elongated hole 36 would also be technically possible, but then the advantages according to the invention with regard to the particularly simple disassembly / assembly would be lost, since the handles 21 would first have to be placed on the clamping slide body 20 and fixed in their position by means of the pivot pins 23. Disassembly / assembly process:

[0040] In Fig. 4a, d, e and f The central position of the elongated hole 36, which penetrates the handle 21 in the vertical direction, is clearly visible. Starting from the groove 34, the underside has a hook shape. The handle 21 therefore has smaller lateral dimensions in the area of ​​the hook 40 on the underside than on the - in the bottom view of Fig. 4dviewed from the rear, where the control surface 22 clearly has a curved shape. The hook 40 defines the slot 36 and extends to the slot opening 42. The flattened shape of the underside in the form of the hook 40 allows a good contact surface for the handle spring 24, as can be seen in conjunction with Fig. 7 is very clearly visible.

[0041] In Fig. 7 A cocking slide body 20 with handle spring 24, mounted pivot pins 23 and handles 21 in different positions is visible. In the upper row of the Fig. 7 is a top view, in the lower row a bottom view. In Fig. 7aThe cocking slide body 20 and the grip spring 24 inserted into a receiving opening on the underside are visible. During installation, the spring action pushes the two legs of the spring apart in the transverse direction 38. If a grip is now pushed onto the cocking slide body 20 from the rear, with the cocking slide body 20 removed, the pivot pin 23 is received through the slotted opening 42 in the elongated hole 36. During this assembly process, the grip spring 24 is pushed "inward" by the hook 40 toward the weapon center plane 32, and the spring action moves the grip 21 into its rest position, see Fig. 7c , folded. In the working position, Fig. 7d , the pivot pin 23 is mounted in the end area of ​​the elongated hole 36, which is further away from the slot opening.

[0042] As from Fig. 7As can also be seen, the cocking slide body 20 has a centrally arranged counter extension 35. This serves as a lateral guide for the control surface 22 and, in the example shown, is designed to complement the shape of the rounding of the control surface 22. By means of a small clearance on the underside of the control surface 22 towards the groove 34, disassembly and assembly as described above can be carried out when the cocking slide body 20 is removed, since the clearance enables displacement via the counter extension 35. In the installed position in the slide 19, however, such displacement in or against the running direction 37 is no longer possible and the handle 21 can only be pivoted between the rest and working positions, or can be displaced within the limits of the elongated hole 36 into a retraction position explained further below.

[0043] Locking effect of the control element 29 and function of the control surface 22: The locking effect of the control element 29 against undesired movement of the cocking slide unit 8 during firing can be simplified as follows. As in Fig. 5a and 5b As can be clearly seen in a cross-sectional view or perspective view, the control element 29 is pre-tensioned downwards in the vertical direction. The control element 29 prevents displacement backwards against the running direction 37, since a locking edge 43 provided on the cocking slide body 20 blocks the movement with the control element 29. The handle 21 in Fig. 5a and 5b is folded, i.e. in rest position.

[0044] If the handle 21 is now pivoted into the working position, the ramp-shaped or gate-shaped control surface 22 formed on the upper side of the handle 21 causes a vertical deflection of the control element 29, as can be seen from Fig. 5c and 5dis clearly visible. The locking edge 43 is thus no longer engaged with the control element 29 and the cocking slide unit 8 can be pulled backwards against the running direction 37. The slide 19 thereby transmits the longitudinal movement to the sliding piece 18 against the force of the closing spring unit 31, see Fig. 2 After releasing the handle 21 in the rearmost position, the handle 21 automatically folds back into the rest position due to the previously described action of the handle spring 24, and the cocking slide unit 8 is accelerated forward. The control element 29 springs back into the locked position, thus preventing the cocking slide unit 8 from moving during (semi-)automatic firing. Manual closing movement (forward assist):

[0045] The clamping slide unit 8 according to the invention can also be used for manual closing movements, compare the sequence diagrams of the Fig. 6a to 6cwhich represent a perspective view. In Fig. 6a the handle 21 is in the rest position, the control element 29 is in the locking position to the chip slide body 20. In Fig. 6b the handle 21 is in the working position, whereby the above-mentioned release of the clamping slide unit 8 can take place backwards against the running direction 37. In Fig. 6c the handle 21 is deflected slightly in the direction of the weapon center plane 32 along its slotted hole direction 33. This displacement is essentially made possible by the shape and alignment of the slotted hole 36 or its orientation to the weapon center plane 32. In conjunction with the Figures 3 and 5 a recess can be recognized on the closing spring unit 31, into which the handle 21 is inserted by means of a nose-shaped closing spring driver 30 (see also e.g. Fig. 4) can engage in the retraction position. Due to the suitable shape and arrangement of the control surface 22, the elongated hole 36, the elongated hole direction 33, and the recoil spring driver 30, the recoil spring unit 31 is automatically "gripped" when the cocking slide unit 8 is retracted to the rearmost position and can be pushed forward in the running direction 37 by pressing the handle 21. The pressure of the retraction movement is transferred from the control surface 22 and / or the deflection limiter 41 and / or the pivot pin 23 to the cocking slide body 20, whereby the pivot pin 23 can be relieved.

[0046] In a preferred embodiment, the handle 21 has a deflection limiter 41. The deflection limiter 41 is, for example, Fig. 4a and 4every clearly visible and primarily serves to prevent undesired over-deflection of the handle 21 beyond the working position. The deflection limiter 41 can preferably be arranged between the control surface 22 and the closing spring driver 30 and limits the pivoting movement of the handle 21 by striking the counter extension 35, as can be seen from the combination with Fig. 8 - bottom row of images - is clearly visible.

[0047] It has also proven advantageous that the orientation of the slot direction 33 largely coincides with the longitudinal extension of the deflection limiter 41, or is even aligned. This relationship is particularly well illustrated in Fig. 8 clearly, in which different handles 21 on the clamping slide body 20 are shown in the rest position (upper row of images) and the working position (lower row of images). Furthermore, Fig. 8It can be clearly seen that - depending on the design of the slot direction 33 - the handle 21 can be deflected to different extents in the working position and consequently protrudes laterally from the upper housing 4. However, it is advantageous if the deflection limiter 41 in the working position is fully supported on the counter extension 35 (compare Fig. 8a, 8b and 8c (bottom row of images). This is made possible by the fact that the slot direction 33 is aligned perpendicular to the weapon center plane 32 in the working position. The orientation of the slot direction 33 relative to the weapon center plane 32 can be described by the opening angle 45. It is thus possible to provide different handles 21 with different opening angles 45 in order to offer the user several options to choose from.

[0048] In Fig. 8dFurthermore, a special embodiment is shown, according to which a cover 44 is pushed onto the cocking slide body 20. The disassembly and assembly of such a "blind" and thus non-functional handle is carried out analogously to the above description. This cover 44 can be used to obtain a cocking slide unit 8 that can only be operated from one side and simultaneously prevent foreign objects from penetrating the interior of the cocking slide unit 8.

[0049] Terms such as "lower area" of a component or device, or, more generally, of an object, mean the lower half and, in particular, the lower quarter of the total height; "lowest area" means the lowest quarter and, in particular, an even smaller part; while "middle area" means the middle third of the total height (or width - length). All of these terms have their common meaning, applied to the intended position of the object in question.

[0050] In the description and claims, "substantially" means a deviation of up to 10% of the stated value, if physically possible, both upwards and downwards, otherwise only in the reasonable direction; for degrees (angle and temperature) this means ± 10°.

[0051] In terms such as "a feather", the word "a" is not to be regarded as a number, but as an indefinite article or as a pronoun, unless the context indicates otherwise.

[0052] The term "combination" or "combinations," unless otherwise stated, refers to all types of combinations, from two of the components in question to a plurality or even all of such components. The term "containing" also refers to "consisting of." Statements such as "more than three" include and disclose any number greater than three.

[0053] The features and variants specified in the individual embodiments and examples can be freely combined with those of the other examples and embodiments and can be used, in particular, to characterize the invention in the claims without necessarily including the other details of the respective embodiment or example.

[0054] In conclusion, one can therefore state: The invention relates to a carbine with a weapon center plane 32, with a barrel 1 with a bore axis 37, a gas drive 2, a slide 18, a recoil spring unit 31, and a cocking slide unit 8 arranged in front of the slide 18, wherein handles 21a,b rotatably mounted about pivot pins 23a,b are urged into their rest position by at least one handle spring 24b. By forming an elongated hole 36 on the handle 21, the cocking slide body 20 can be displaced in both the pull and push directions along or against the barrel direction 37. The elongated hole 36 has a slotted opening 42 for simplified assembly of the handle 21.

[0055] By optimizing the design of the handle 21, or rather the orientation of at least the elongated hole 36, the deflection of the handle 21 in the lateral direction can be easily optimized by a person skilled in the art for various applications.

[0056] The clamping slide unit 8 according to the invention is mounted on a carriage 19 arranged axially in front of the sliding piece 18 and movable in the axial direction and can be inserted or removed laterally relatively easily.
