Abstract

The invention relates to a cocking slide for an existing, gas-powered carabiner, in particular of the AR15 or M4 type. It can be operated on both sides and has a shaft (2), the end section (24) of which has a lateral widening on both sides, on which, rotatable about a pin (26) and urged into a fixing position by at least one spring (33, 43), an active handle (3) with a locking extension (37) and a passive handle (4) are arranged. When the active handle is rotated against the spring force, the locking extension is released; when the passive handle is rotated, it also rotates the active handle. To relieve the pin (26), the release position of the first handle is provided by a support surface (29) on the side Widening is defined, on which an internal stop surface (38) of the active handle (3) rests in the release position for direct force transmission; this applies mutatis mutandis to the passive grip.

Description

The invention relates to a cocking slide for an existing carabiner or a carabiner with a cocking slide, according to the preamble of claim 1.

In numerous rifles (carbines), especially those of the AR15 or M4 type, cocking slides have been known for many years as independent parts and are commercially available that meet a wide variety of requirements. It is therefore assumed in the following and in the claims of the carbine as existing, the invention relates to a cocking slide adapted to this, which thus fits geometrically and functionally into the weapon so that it can be used with the cocking slide according to the invention. The following can be briefly stated as a general technological background:
Cocking slides are provided for carbines (rifles) so that the weapon can be loaded manually; If, for example, there is no cartridge in the chamber and a new magazine has been attached, the rotating lug lock is opened by means of the cocking slide and the slide in which the lock head is mounted is pulled backwards, thereby tensioning the closing spring. During the advance movement, the cartridge is drawn into the chamber and the breech is locked. In the case of automatic firing, these processes usually take place by means of the closing spring, which is tensioned with every movement of the slide.

The cocking slide should be operable for both left-handers and right-handers alike. The cocking slide should also not participate in the sequence of movements of the slide and breech after the shot has been fired. On the one hand, this would increase the mass of the moving parts and make it necessary to provide stronger springs and thus to ensure a stronger introduction of force through the gas drive, which in turn increases the acting forces overall, which makes the weapon as a whole more restless, since it is moving masses acts. On the other hand, it would be very annoying, especially with AR-type rifles, if the cocking slide was deflected backwards towards the shooter after each shot. Finally, the cocking slide should change the outer contour of the weapon as little as possible and, above all, should not have any protruding parts, since these can lead to obstructions and problems, especially in the field.

Countless proposals are known from the prior art; only the most important are briefly dealt with below.

The U.S. 7,240,600 discloses a cocking slide which can be actuated on both sides, two handle pieces being provided which are pivotable about vertical axes and which are urged into their rest position by a compression spring provided between the two handle pieces. In this rest position, the left grip engages with a hook on the weapon housing and thus prevents unwanted movements with the slide. When the left handle is operated against the force of the spring, the hook comes out of the recess in the housing and releases the cocking slide to move backwards. When the right handle is actuated, a fork-like device provided on it entrains a projection that engages in the groove between the two fork prongs and thus also brings the left handle into the active position in which the hook does not engage the housing of the weapon and so the cocking slide can also be activated and used with the right handle. The advantage of this concept is that it uses only a few components, the disadvantage lies in the interaction between the groove and the projection, which is prone to contamination because of the tight tolerances to be observed and the blind hole-like shape of the groove.

The U.S. 8,336,436 discloses a cocking slide with a one-piece lever that can be swiveled either to the left or right, a spring-loaded mechanism ensuring that when swiveled, regardless of which side, the hook comes out of the area of the recess in the housing of the weapon. The mechanism for releasing the hook is complex and relatively filigree and consists of a large number of components, which makes it relatively complex and expensive.

The U.S. 9,377,258 discloses a cocking slide in which the two handle pieces each engage with a projection in the groove of a spring-loaded tube and are thus pressed into the rest position. When one of the two handle pieces is actuated, the other handle piece is moved along via this tube and the groove and so the hook in any case gets out of the area of the housing. The almost perfect symmetry makes this solution elegant, but assembling the tube under the handle in the groove is difficult and, above all, susceptible to dirt.

The U.S. 9,683,795 discloses a cocking slide with a certain similarity to the one mentioned above U.S. 7,240,600 only this construction is more complex and more asymmetrical.

The U.S. 9,423,195 goes a completely different way and achieves the two-sided operability only to a very limited extent, because for this it is necessary to simply use the existing handle on the left or right by changing the installation direction of the cocking slide from a prone to a back position, which is in the field is not an acceptable solution and can only be viewed as "quasi-bilateral".

The U.S. 9,366,489 is unique in that it dispenses with handles and instead uses a rope, cord, or the like mounted on the lever on the one hand, and on the opposite edge area of the cocking slide on the other, so that the cocking slide is actuated by pulling the cord.

Equally exotic, albeit in a different way, is the solution U.S. 9,791,225 in the fixations or connections between the cocking slide and the upper housing of the rifle instead of a spring-loaded hook using magnets, which requires both high-temperature magnets and tight fits, since the closing forces decrease with the square of the distance.

The U.S. 10,012,461 discloses a very sophisticated mechanism with two springs, a gate or cam and a gate or cam follower, which makes it possible to operate a one-piece handle either from the left or right and over the setting (cam) and the cam follower to get the lever free. This mechanism is filigree and consists of numerous components, so it is complex.

The content of the U.S. 7,240,600 , the U.S. 8,336,436 , the U.S. 9,377,258 , the U.S. 9,683,795 , the U.S. 9,423,195 , the U.S. 9,366,489 and the U.S. 10,012,461 is made part of the content of the present application by reference for the jurisdictions in which this is possible.

Apart from the problems and disadvantages mentioned in each case, all the proposals mentioned have in common that the actuating forces are usually introduced into the clamping slide via the pivot pins (pins, dowel pins) of the handles, which makes both these pivot pins and their receptacles in the clamping slide mechanically strong burdened and this also in a dynamic, namely thrusting way.

It is therefore the aim and object of the invention to provide a cocking slide of the type mentioned, in particular for a carbine (rifle) of the AR15 or M4 type, which does not have the disadvantages mentioned in each case and in particular manages with few components and is mechanically robust and durable.

According to the invention, these goals are achieved by a cocking slide with the features specified in the characterizing part of claim 1, in other words the handles have stop surfaces that interact with opposing surfaces on the shaft when actuated and thus reduce or eliminate the load on the pins. In one embodiment of the invention, the contact surfaces between the two handles are designed so that when the passive handle is operated, there is a rolling-sliding relative movement, and that when the active handle is operated, the distance between these surfaces increases, which means that dirt is largely automatic removed. Further refinements are given at the end of the description with reference to the drawing by way of example.

The invention is explained in more detail below with reference to the drawing. It shows or shows:

• the Fig. 1 a cocking slide according to the invention with the parts of the weapon in which it is used, in a perspective exploded view,
• the Fig. 2 the cocking slide of the Fig. 1 in a perspective exploded view,

It should be assumed that the further explanation is based on a cocking slide for an AR 15 rifle. Of course, the features according to the invention can also be used there independently of the adaptations for other existing weapons. In particular, mirror-image designs in which the locking hook is arranged on the right handle can be designed without problems for the person skilled in the art.

The terms "front", "forwards", etc. are used in the common sense, that is, the muzzle of the rifle is "in front", the magazine protrudes "downwards", "left" is "forwards" when viewed to understand, etc. It is in the Figs. 2 and 3 a Cartesian axis system is shown in each case, the arrow 51 pointing forward (direction of travel), the arrow 52 pointing to the left and the arrow 53 pointing upward. The weapon center plane is defined by the barrel axis and the direction parallel to arrow 53, intersecting the barrel axis.

The Fig. 1 shows the installation situation of a cocking slide in an AR15 carabiner. As in the prior art, the invention is also aimed at gripping the slider (= bolt carrier) 12 in the area of the gas intake (= gas key) 13 and pulling it backwards during the manual loading process. This movement takes place against the force of the closing spring (not shown), which moves the slide 12 forwards after the cocking slide 1 is released, a new cartridge being inserted from the magazine into the chamber of the barrel and the bolt head locked. This charging process is well known to the person skilled in the art, which is why in Fig. 1 only the installation situation of the clamping slide 1 and the slide 12 in the upper housing 5 are shown. The dashed lines illustrate this Recording of cocking slide 1 and slide 12 in the upper housing 5 of a rifle of the AR15 type, schematically. In order to lock the cocking slide 1 on the housing 5 after the shot has been fired and to prevent it from loosening or even "running" with each shot, all such cocking slides have a locking device, which is particularly often used as a locking extension 37 ( Fig. 2 ) is trained. This locking extension 37 is provided for engagement in a housing recess provided for this purpose, the "clamping slide holder" 11 (= latch lock), and is mostly in the form of a pawl or a hook (also denoted by 37).

The Fig. 2 shows a schematic exploded view of the cocking slide 1 of FIG Fig. 1 represents, which has an integrally (one-piece or firmly connected) formed shaft 2 as a central element. At its front end, the shaft 2 has a front section 21, following counter to the running direction, a central section 23 and an end section 24 that is widened laterally in both transverse directions 52 with respect to the central section.

On the front section 21, an extension is formed in the downward direction, that is, against the direction 53, with an opening 22 for the gas key 13.

The middle section 23 of the clamping slide 1 has a longitudinal groove on its underside ( Figure 4a ), which, in the event of gas escaping from the slider 12, ensures a guided removal of the gases against the running direction 51 towards the rear to a gas outlet 27. This gas outlet 27 is on the underside of the cocking slide 1 as an arcuate recess, especially in the Figs. 3b and 4a evident. The arch shape ensures that the gas can escape again, away from the shooter's face.

As in Fig. 2 shown, two handles 3, 4 (a left, active, handle 3 and a right, passive, handle 4) are attached to the end section 24 by means of pins 26 (= pin) or the like so that they can pivot about axes parallel to the vertical axis 53. Active grip only because it has the locking hook and, when actuated, deflects it in the "left" direction 52, and the cocking slide 1 can be pulled backwards.

The handles 3, 4 have groove-like recesses 31, 41 which are provided on the rear and which are designed at least essentially complementary in shape to the two side arms of the end section 24. Thus, the handles 3, 4 can be placed or slipped over the end section 24 relatively easily and fixed by means of pins 26. The handles 3, 4 have an inner contour which is shaped in such a way that, in the installed position, the distance from the rear side in the direction of the end section 24 increases outward, that is to say in the transverse direction 52.

This fact is particularly good Fig. 6 evident. In other words, the end section recess 31, 41, viewed from the top or bottom view through the sectional plane along the line VI-VI of FIG Figure 4a , in the “left” or “right” direction 52 have an increasingly widening cross-section. The handle path 39, as in Fig. 4 With Fig. 6 Looking together is very clearly visible, is - viewed in the rest position - designed to expand outwards. The course of the internal stop surfaces is 38.48 in Fig. 6 is shown curved, but can also be linear or even stepped, whereby it should be taken into account that they are designed essentially complementary in shape to the end section 24 and in particular the support surfaces 29. As a result, when at least one handle 3, 4 is actuated, the stop surface 38, 48 will come into contact with the support surfaces 29, as will be explained below.

The handles 3, 4 partially accommodate springs 33, 43, which are supported on the end section 24 in the spring recesses 25 provided for this purpose. As a result, in the rest position, both handles 3, 4 are biased forward in the running direction 52 and a pivoting movement backward is made possible. The Fig. 2 also shows that the right handle 4 has a contact surface 44 facing the shaft 2. This contact surface is designed analogously on the handle 3 as a contact surface 34 and prevents the handles 3, 4 from "overshooting" the front-inward direction when the cocking slide 2 is moved forward, be it manually or by the bias of the springs 33, 43 Central section 23 of the shaft 2. These contact surfaces 34, 44 thus form a kind of stop up to which the handles 3, 4 can be biased forward.

The Figs. 3a, b show the handles 3, 4 in the rest position, once in a top view, once in a view from below, the hook 37 on the active handle 3 can be seen just as well as the adaptation of the contours of the handles 3, 4 to the contours of the end section 24.

As already stated, the pins 26 or spring pins, dowel pins or the like, which fix and rotate the handles 3, 4, are normally very heavily loaded when the cocking slide 1 is operated manually as intended. According to the invention, the introduction of force takes place when one or both handles 3, 4 are operated by gripping and pulling the handle surfaces 35, 45 over internal stop surfaces 38, 48 of the handles, which come into contact with support surfaces 29 of the end section 24. The force is thus transmitted directly to the shaft 2, which increases the rigidity of the system and significantly relieves the load on the pin or pins 26. "Internal" stop surface because it is covered both above and below, which protects it against contamination and prevents any risk of entrapment.

The synopsis of the Figs. 4b -c shows that when one of the handles 3, 4 is actuated, a distance between the surfaces, called a handle path 39, 49, has to be overcome and then the load is transferred by supporting the internal stop surfaces 38 and / or 48 on the respective support surfaces 29. This measure creates a "two-point support", that is to say on pin 26 and at least one contact point between support 29 and stop surfaces 38, 48, which increases stability. This connection can also very easily come from Fig. 6 can be seen in which a sectional view on the plane of the line VI-VI in Figs. 4a, c is shown "up".

In the ideal case, when at least one handle 3, 4 is actuated, flat support of the support surfaces 38, 48 on the end section 24 is achieved, as a result of which the pin (s) 26 merely assume a kind of guidance. The introduction of force is therefore primarily not via the pin or pins 26, but rather through the comparatively large-area contact, as just described, as a result of which the pins 26 are significantly relieved.

To operate when using the "passive" (right) handle 4 is to be carried out: The translation of the force or movement when operating the right handle 4 on the Hook 37, in order to release it, takes place via an actuator 46, which can be seen well in FIG Fig. 2 , which acts on the back of a counterpart of the actuator 36 on the active handle 3 and thus also deflects the left handle 3. The Figure 5b A bottom view (!) shows this deflection of both handles when using the right handle 4 with the contact between the two actuators 46 and 36.

From the Figs. 5a, b it can also be seen that the shaft has a shaft stop 28 formed on its underside. The shape of the shaft stop is essentially predetermined by the radii of the handles 3, 4 with respect to the axes of the pins 26 in this area and thus has arcuate recesses 52 in the transverse direction. In a preferred embodiment of the invention, it is provided that the shaft stop 28 serves as an abutment for the passive actuator 36 (and thus indirectly also for the actuator 46 in the application) when one or both handles 3, 4 are actuated, whereby on the one hand a limit position for the pivoting is precisely defined and, on the other hand, a third bearing point is created opposite the contact area of the respective internal stop surface 38, 48 with the support surface 29. As a result, the pins, their holder in the end section 24 of the shaft 2 and the bearing for them in the respective handle 3, 4 are greatly, ideally almost completely, relieved. The fact that the respective contact surfaces and the pins have to meet certain tolerances does not pose any problems to the person skilled in the art with knowledge of the invention and the preload with the springs, which prevent any slagging, rattling and vibration.

• Die Griffe 3 und 4 sind "vollflächig" von vorne betätigbar, wodurch eine gute Krafteinleitung und auch in Stresssituationen eine zuverlässige Betätigung ermöglicht wird.
• Die Griffe 3 und 4 können jeweils einzeln oder auch gemeinsam betätigt werden und in allen Fällen wird dadurch die Freigabe des Arretierfortsatzes 37 ohne jedes weitere Zutun bewirkt.
• Durch die interne Vorspannung mit Federn 33,43 ist eine Verschmutzung unwahrscheinlich und einem "Klappern" der Komponenten effizient vorgebeugt.
• Durch die geringe Anzahl an Bauteilen ist die Fertigung kostengünstig, die Betriebssicherheit begünstigt.
• Die Anlageflächen 34,44 dienen dazu ein "Überschwingen nach innen" und damit ein mögliches Verklemmen am Rahmen der Waffe zu Verhindern.
• Die Übersetzung der Kraft von "rechts" bei Benutzung des rechten Griffes 4 erfolgt über dessen Aktuator 46 auf den "passiven Aktuator 36". Ein "Überschwingen" wird durch den Schaftanschlag 28 verhindert, der auch das Einleiten der Betätigungskraft ohne Überbeanspruchung der Stifte ermöglicht.
• Die Griffe 3, 4 stützen sich intern nach Überwindung eines Griffwegs 39 am Endabschnitt 24 ab; hierdurch wird eine Auflage ausgebildet, welche die, insbesondere bei Vorhandensein des Schaftanschlags 28, die Lagerung an den Pins 26 und dies selbst entlastet und ein Anreißen z.B. mit Handschuhen oder dgl. an einer oder beiden Seiten (Griffe 3,4) erlaubt, ohne dass filigrane Bauteile versagensanfällig wären.

The advantages that can be achieved by the invention or its embodiments are specified below:

• The handles 3 and 4 can be actuated from the front "over the entire surface", which enables a good introduction of force and reliable actuation even in stressful situations.
• The handles 3 and 4 can each be operated individually or together, and in all cases this causes the locking extension 37 to be released without any further action.
• The internal pre-tensioning with springs 33, 43 means that contamination is unlikely and a "rattling" of the components is efficiently prevented.
• Due to the small number of components, production is cost-effective, and operational reliability is enhanced.
• The contact surfaces 34, 44 serve to prevent "overshooting inwards" and thus a possible jamming on the frame of the weapon.
• The translation of the force from the “right” when the right handle 4 is used takes place via its actuator 46 to the “passive actuator 36”. An "overshoot" is prevented by the shaft stop 28, which also enables the actuation force to be introduced without overstressing the pins.
• The handles 3, 4 are supported internally after overcoming a handle path 39 on the end section 24; As a result, a support is formed which, in particular when the shaft stop 28 is present, relieves the bearing on the pins 26 and this itself and allows one or both sides (handles 3, 4) to be torn off, for example with gloves or the like filigree components would be prone to failure.

In summary, it can be stated that the invention is essentially a cocking slide for an existing, gas-powered carabiner, in particular of the AR15 or M4 type with a housing 5, the cocking slide 1 having a shaft 2 with a front section 21, a middle section 23 and an end section 24, the front section 21 reaching into the area of a gas receptacle 13 of a slide 12 of the carabiner and a lateral widening of the shaft 2 for receiving an active handle 3 and a passive handle 4 is provided on the end section 24 in the transverse direction 51, which is provided on the Widening are each rotatably mounted by means of a pin 26, the active handle 3 being formed integrally, preferably in one piece, with a locking extension 37, and is designed so that it can be rotated between two positions, the locking extension 37 in a first fixing position with a cocking slide holder 11 of the housing 5 of the karabiner cooperates and fixes the cocking slide 1 with respect to the housing 5, and in a second release position does not interact with the clamping slide holder 11 and releases the clamping slide with respect to the housing 5, the passive handle 4 being designed so that it is in operative connection with the active handle 3 is brought, both handles 3, 4 are urged by at least one spring 33, 43 into the position that corresponds to the fixing position, characterized in that the release position of the first handle by a support surface 29 on the widening of the end portion 24 is defined, on which an internal stop surface 38 of the active handle 3 rests in the release position. The desired relief of the pin 26 is thus achieved with a few, robust components. Damage to the connection points or pins 26 as a result of violent movements, such as when the clamping slide 1 is pulled back during use, can thus be efficiently avoided, the number of components being comparatively small.

Refinements protect, for example:
A cocking slide, which is characterized in that the support surface 29 lies in a plane essentially parallel to the normal direction 53. In this way, the force is transmitted as directly as possible when using the cocking slide and without introducing an additional torque about the transverse axis.

A cocking slide, which is characterized in that the internal stop surface 38 lies in the release position in a plane essentially parallel to the normal direction 53. This results in flat contact with the support surface during use without any punctual stress.

A cocking slide, which is further characterized in that the support surface 29 is at a greater distance from the center plane of the weapon than the pin 26. Since the handle is gripped on the outside, the force is transmitted without great deflection and the pin is further relieved.

A cocking slide, further characterized in that a shaft stop 28 is provided on the end section 24 for an opposing surface of the active grip 3, which is arranged closer to the weapon center plane than the pin 26. This creates a further contact surface for power transmission.

A clamping slide of the latter type, which is characterized in that, in the release position of the first handle 3, it contacts both the support surface 29 and the stop. Thus, the pin 26 is largely, ideally completely, relieved during use.

A further developed cocking slide, which is characterized in that the passive handle 4 is formed in one piece with an actuator 46, which is arranged behind a passive actuator 36 formed in one piece with the active handle 3, and that the two actuators are arranged closer to the weapon center plane than the Pins 26. This creates a simple and very robust transmission of the torque required for unlocking to the active handle when the passive handle is used.

A clamping slide of the latter type, which is characterized in that the counter surface for the shaft stop 28 is formed on the front side of the passive actuator 36. In this way, when the handle is used, the active handle is completely relieved after unlocking; with the passive handle, its pin is also relieved by its contact surfaces with the end section.

A further developed clamping slide, which is characterized in that each of the handles 3, 4 has a groove on its rear side, the end section recess 31, into which the lateral widening of the shaft 2 protrudes, and that the pins 26 are arranged in this area. This prevents tilting moments about the transverse axis 52 and protects the arrangement as a whole from the ingress of dirt; in the technical sense, the shallow groove is preferably in a plane normal to the vertical axis 53.

A cocking slide, which is further characterized in that a spring 33, 43 is provided for each handle 3, 4, that these springs are compression springs, preferably helical springs, and that their axis is parallel to the direction of travel 51 with a deviation of no more than 10 °, preferably not more than 5 °. This means that the most robust type of spring can be used; the arrangement in the direction of travel 51 means that no additional moments occur; By pre-tensioning the springs, the rattling or slagging of the handles is avoided.

A clamping slide of the latter type, which is characterized in that for receiving each of the springs 33, 43 depressions in the walls of the end section recess 31 and a recess in the contour of the lateral widening of the Shank 2 are formed. In this way, the springs are secured against loss without additional components.

A further developed cocking slide, which is characterized in that a gas opening 22 is provided on the front section 21, which opens into a longitudinal groove on the underside of the shaft 2 facing the barrel, which in turn at the end section 24 in a, preferably at least oblique, pointing at least in the transverse direction 52 forward gas outlet 27 opens. In this way, when gas escapes, the gas can be diverted harmlessly and yet be drained away by the user.

A cocking slide, which is further characterized in that the handles 3, 4 each have a contact surface 34, 44 in their front area facing the shaft 2, which under the action of the springs 33, 43 comes into contact with the associated side surface of the shaft 2 and thus prevent further rotation. Without an additional component, it clearly defines a rest position for the handles, which do not rattle due to the preload of the springs, with "forward assist" moments can be derived here.

A clamping slide of the latter type, which is characterized in that the rotation of the handles 3, 4 between the position when the contact surfaces 34, 44 and the position when the support surfaces 29 contact the outer contour of the handles defines the handle path 39. Conversely, this means that the desired length of the grip path 39 can be achieved through the appropriate arrangement of the surfaces mentioned.

A clamping slide which is further developed in that the axes of the pins 26 run parallel to the normal direction 53. This is manufacturing technology and optimal for use.

All statements made for the active handle 3, especially with regard to the contact surfaces, also apply, mutatis mutandis, to the passive handle 4.

A cocking slide which is further characterized in that the narrow surfaces of each handle 3, 4, which face one another in the end section recess 31 on the one hand and the bottom of the end section recess 31 including the support surface 29 on the other hand in the rest position in the rest position in the area in front of the pin 26 and in the release position in the area laterally in the area that is at a greater distance from the weapon center plane than the pin 26. On the one hand, this amounts to an enlargement of the support surface 29 and, on the other hand, to an additional safeguard against overshooting.

In the description and the claims, the terms "front", "rear", "top", "bottom" and so on are used in their usual form and with reference to the object in its usual position of use. This means that in a weapon the muzzle of the barrel is "front", that the breech or slide is moved "back" by the explosion gases, etc .. Transverse to a direction essentially means a direction rotated by 90 °, Unless otherwise indicated, the various items shown in Figs. Coordinate system 51, 52, 53 drawn and described is specifically pointed out

It should also be pointed out that in the description and the claims, statements such as "lower area" of an object means the lower half and in particular the lower quarter of the total height, "lowest area" the lowest quarter and in particular an even smaller part; while "middle area" means the middle third of the total height (width - length). All of this information has its common meaning, applied to the intended position of the object in question, unless otherwise stated.

In the description and the claims, "essentially" means a deviation of up to 10% of the specified value, if it is physically possible, both downwards and upwards, otherwise only in the meaningful direction, for degrees (angle and temperature) this means ± 10 °.

All quantities and proportions, in particular those to delimit the invention, unless they relate to the specific examples, are to be understood with a tolerance of ± 10%, thus for example: 11% means: from 9.9% to 12.1%. At Designations such as: "a solvent", the word "a" is not to be seen as a numerical word, but as an indefinite article or as a pronoun, if nothing else emerges from the context.
