Abstract

The handle is movable out of a rest position, in which it points in the longitudinal direction of the weapon, into an operated position, in which it is so far displaced to the side or pivoted that it can be engaged for operating the breech. A securable spring mechanism in the tension state loads the handle in the rest position against a securing point. A movable spring-loaded slide (30) locates against a movable stop. The stop is movable by impression of the handle out of the movement path of the slide. A spring (60) is provided which loads the slide (30) after release by the stop and loads the handle for displacement or pivoting.

Description

The invention relates to a loading lever mechanism for a Self-loading handgun, with one with its breech connected, swiveling or displaceable, with a sprung handle provided loading lever, the Handle from a rest position, in the longitudinal direction the weapon has, is movable into an actuating position, in which they compared to the longitudinal direction as far as the Side is offset or pivoted that they can be operated of the closure is within reach.

With older self-loading handguns, the loading lever was firmly attached to the closure, protruded on the outside out of the gun and accompanied the Movement of the clasp. There was a great danger here that the loading lever on a camouflage net, branch o. The like. Catch and thereby cause a load inhibition could.

One therefore has the generic type mentioned at the beginning Loading lever developed according to DE 19613987, for example is centered over the barrel of the weapon and is in a rest position occupies in which it is arranged parallel to the barrel.

Only when loading, i.e. when the lock moves by the shooter's hand, he is from this side folded out to the left or right - depending on whether the shooter is right-handed or left-handed - so that he can be gripped for loading. If the shooter Lets go of the loading lever, it folds back into the front its rest position.

However, the loading lever must be exposed to the top a grip by the shooter's hand even with thick ones Allow mittens. The danger that the dated Locking moving loading lever disturbing with foreign bodies collides, is reduced in this way, but it is still given. If, for example, the one in cover In the event of a burst of fire, quickly raise the gun pulls, then the loading lever can very well on a branch o. Like. Accumulate and cause a charging failure.

Another situation arises with weapons where it is structurally not possible, the loading lever freely from above attached accessible.

The aim of the invention is therefore the loading lever mechanism of the type mentioned to further develop that he in a trajectory covered from above and below can walk without sticking out to the side, but still effortlessly moved outwards (offset or swiveled) can be that he is wearing gloves loading is easy to grasp.

This goal is achieved according to the invention by a lockable spring mechanism, which in the tensioned state handle in the rest position is loaded against a rest, can be released from the catch without reaching around the handle and then, by relaxing, the handle in Direction of their operating position moved so far that this is readily accessible.

The term "spring mechanism" is too broad understand and means a mechanism in which at least a resilient part is involved.

This resilient part can be the closing spring of the weapon himself, who opposed the loading lever with his handle presses a swiveling part, which by means of an external Projection or the like. ' can be pivoted and take the handle with it and move it outwards. Prefers is the spring of the spring mechanism set up by their strength then when a lock is released will move the handle outwards automatically.

The spring mechanism preferably has a push-in type Trigger for releasing the latch on (claim 2), which also with chunky over-gloves can be operated, but preferred laterally movable at such a location is that it is covered by covering material, branches (e.g. when crossing a thicket) or similar foreign bodies or can hardly be operated.

A push button on the side of the weapon can be used as a trigger be let in; however, the trigger of is preferred the handle formed or actuated (claim 3). It In this case, it is sufficient to move the handle sideways Press to cause them to go out in one ready-to-hand position is moved. The weapon therefore needs no other controls; besides that is Handle the element to which the trained shooter automatically intervenes when he wants to load through or a jam must fix. According to the development of the invention then he only needs the handle with his fingertip touch or tap to cause them to touch him sort of jumps into your hand.

So there is no need for a separate charging handle. There is preferably a movable, spring-loaded slide against a movable stop, the stop by pushing the handle out of the path of movement of the Slider is movable, and a spring is provided which the slider indirectly after the release by the stop burdened and in turn the handle for transfer or pivoting charged (claim 4). The mobile The stop is the trigger. Because the slider with the handle not through a fixed articulation, but connected by a flexible linkage (spring) the slide can move after its release, even if the handle is still pressed in. Will the Released handle, then it moves under the effect the spring to the outside and can be gripped immediately.

It would be conceivable to return the spring-loaded Slider to use the locking movement in its rest position. Preferably, however, the handle already moves when When the actuation position is reached, slide back again so that the stop again in the path of movement of the Slider can move back (claim 5). So it is possible for the shooter, increased readiness to load (e.g. guarding prisoners) make that he swings out the handle and even if necessary. If there is no loading process, then but the handle can then return to its rest position be spent that they just up to their operating position is moved and released.

The stop could be on a sliding carriage to sit; however, the stop preferably sits on a pivotable Locking lever, which by a spring in the Slider-holding position is loaded (claim 6). A such locking lever can when he to the longitudinal center line of the Loading lever mechanism is symmetrical, with appropriate training the handle or the loading lever and the slide be effective in both directions. That is, the handle releases the slide lever, regardless of whether it from the right or from the left. The loading lever mechanism is therefore for both legal and Left-handed shooters can be used.

If the stop sits off-center, then it is sufficient to Turn the locking lever to use the loading lever mechanism to be set up by right or left-handed shooters.

It is further preferred (claim 7) that the slide loaded by a preferably helical compression spring is, one end of which is extended and the locking lever charged. It becomes the function by a spring two springs and thus the structure of the loading lever mechanism simplified. If also that extended End is centered, then it can be in its installed position remain even if the locking lever is turned over.

The fulfillment of two functions by a single spring is also made possible that the slide with a Swivel part is engaged, which in the movement of the Slider is pivotable through this and with the spring acts on the handle to the handle by the swivel out moving slide swiveled swivel part and when the slide is returned towards its rest position to burden (claim 8). Furthermore, the handle by this spring with the retracted and locked Slider forcibly returned to its rest position. It is therefore not the swing of the clasp forward loading lever mechanism required to move the handle back to its rest position.

In some cases it is necessary to reclose load in addition to the effect of the closing spring at the front, especially when the shooter does not close the breech snaps forward, but slowly pulls him forward leads to avoid the tell-tale through-loading noise. Then it may be possible that the force of the closing spring is no longer sufficient to lock the closure or to move the extractor claw over the edge of the cartridge.

In this case, there is either an unevenness in the lock trained to close the shutter through the ejection window to push forward with the thumb, or has at improved versions of the loading lever mechanism set up that the outward loading lever in its Location can be blocked.

Therefore, according to a development of the invention, it is proposed that that the loading lever with a longitudinal Elongated hole on an axis firmly connected to the lock is pivotally mounted and in its working position lengthways the slot is movable into a holding position, in which one stop in front of and one behind the slot support the fastener firmly attached counter supports (Claim 9). So it is possible to protrude transversely Block the position of the handle by pushing it in. If the handle is pulled out again, then it swings back to their rest position.

All the individual elements shown in the figures are worn throughout the same reference numerals, so that the Description of an item performed using a figure also applies to all other figures in which the item is shown.

Figure 1 shows the loading lever mechanism in plan view and in a position he takes in a gun, the one with horizontal soul axis kept ready to fire becomes. "In front", that means the muzzle of the firearm, lies to the left of Fig. 1. "Above" and "below" correspond to the label in Fig. 1

1 and 2, the loading lever mechanism is assembled shown, while in Fig. 3 to 8 main elements of this Mechanism are shown, namely the top views of the 3, 4 and 6 and the views of FIGS. 5 and 8 of below in the same orientation as in Fig. 2 and the side view 7 in the same orientation as in Fig. 1, but on different scales, for details better represented.

The loading lever mechanism is on a closure part 10 assembled, shown broken off in Fig. 1 and 2 behind is. This closure part is on its (not shown) rigid back with a not shown Lock carrier connected. The closure part 10 has a open towards the front, designed as a horizontal blind hole Spring bore 12 on, as well as a flat, strip-shaped, horizontal, below the bore and adjacent to it, self-supporting loading lever bracket 14. On the loading lever bracket 14 is in one at the end of the front third Through hole attached to a vertical axis 18, the protrudes upwards. This axis 18 is circular cylindrical, with the exception of a recess 19, which is in the form of an annular groove with a rectangular cross-section at the middle of the axis 18 is formed. Above the spring bore 12 and in parallel a cover plate 16 is inseparable from the loading lever carrier 14 appropriate. The rear portion of the cover plate 16 sits on the closure part 10 and its front section receives the upper end of the axis 18. The cover plate 16 ends in front in an upper, semicircular forward bulged upper end edge 15. Located below this set back, a lower one, towards Indented, semicircular front edge 17. The front edges 15, 17 are on the geometric axis of axis 18 centered.

A helical compression spring is seated in the spring bore 12 20, the front end in a straight bending leg 22 passes, which is at the level of the top of the spring bore 12 extends forward.

1 and 2 is an elongated, substantially flat, horizontally extending slider 30, the top view of which is shown in detail and on an enlarged scale Scale is shown in Fig. 3.

The slider 30 consists of a rear, center, itself longitudinally extending longitudinal strip, the one Spring guide 31 forms a widened, elongated, longitudinally extending center plate and one front, laterally from the longitudinal center of the slide 30 arranged, extending nose. This Nose ends at the front in a forward-facing manner arcuate locking recess 36, on the two longitudinal edges connect, one of which is groundbreaking Longitudinal edge forms a contact edge 37.

In the front part of the middle plate, opposite the rear Part of the middle plate is slightly widened there is a central round bore 39, the diameter of which a tolerance dimension is larger than the outside diameter of the Axis 18. This round bore 39 is set back and in the middle through an elongated hole 38, the width of which is one Tolerance dimension is larger than the diameter of the recess 19 of the axis 18.

Between the side edge of the middle plate and the elongated hole 38 and in the top view to the right of this, in the direction referred to the front, is a bolt 34 with a flattened, attached to the side facing the center line in such a way that it extends down. On the opposite The side edge of the middle plate is on this an upward and downward engagement lug 35 attached.

Behind the slot 38 is an elongated, substantially rectangular, continuous recess 33 in the slide 30 introduced, the width of which is a little larger than that Diameter of the round bore 39.

Between the rear edge of the recess 33 near the rear End of the middle plate are, from this upwards protruding, two spring retaining pins 32 attached. These spring retention pins 32 are symmetrical to each other on both sides the center line and have a mutual Distance on, which is about the diameter of the bending leg 22 corresponds.

The one adjoining the middle plate towards the rear Spring guide 31 has a width which is dimensioned in this way is that the helical part of the compression spring 20th can easily be postponed. The spring guide 31 A bulge on either side near its front end on, at least one of them by a turn of the Compression spring 20 is engaged, so that this is not of the spring guide 31 can slip.

With the compression spring 20 seated on the spring guide 31 grips the bending leg 22 from behind between the two spring retaining pins 32 and extends over the recess 33 and forward as best in it Fig. 2 can be seen. The helical part of the compression spring 20 is supported on the bottom of the spring bore 12 and pushes the slider 30 forward.

The bolt 34, the engagement lug 35 and the spring retaining pins 32 preferably extend around the same thing Measure not only on one side of the slide 30, but on both sides to allow the slide 30 not only in the position shown in the drawing, but can also be installed with the bottom facing upwards as will be explained below.

Is located directly above the slider 30, on this a locking lever 40, which in FIG. 4 shown on an enlarged scale compared to FIGS. 1 and 2 is.

This locking lever 40 has two to each other by about 165 ° offset legs on, with one end with each other are connected. Located at the junction there is a bore 44, by means of which the locking lever 40 is pivotally mounted on the axis 18.

At the rear, free end of one leg is a fixed spring pin 42 up and down while at the front, free end of the other leg fixed locking pin 46 protrudes up and down.

If the locking lever 40 with its bore 44 on the axis 18 is attached, then the protruding downward grips Section of the spring pin 42 in the recess 33 of the Slider 30, while the bending leg 22 against the the upstanding portion of the spring pin 42 is present. He loads it in such a way that the locking lever swiveled counterclockwise in plan view until the spring pin 42 against the edge of the Recess 33 strikes. In the rest position shown in Fig. 2 is the locking recess 36 of the slider 30 by the Compression spring 20 pressed against the locking pin 46 and thereby the locking lever 40 prevented from pivoting. Of the upwardly protruding portion of the locking pin 46 can at Swiveling the loading lever 70 (Fig. 7 and 8) of the latter Gripped nose 72 and pressed out of the recess 36 become; this will be described in detail later.

Under the slide 30 there is essentially one flat, slidable from below on the slide 30 adjacent control part 50, which is approximately the same in Fig. 5 Scale as shown in Figs. 1 and 2. The control section 50 is designed as a one-armed pivot lever with a bore 52 with which the control part 50 is pivotable sits on the axis 18. A lever arm extends to in front and carries one firmly at its front end protruding groove pin 56, which is a circumferential groove having. At the peripheral section surrounding the bore of the control part 50 are opposite to each other and on both sides two notches 54 formed obliquely to the rear. At the bottom, the bore 52 surrounds one ring bead 58 protruding below.

After installation, the ring bead 58 lies on the top of the loading lever bracket 14. The bolt 34 of the slide 30 engages in the (in the plan view) right of the notches 54 on.

A double leg spring 60 (FIG. 6) with an eye 66, a straight first leg 62 protruding therefrom and a parallel to it, arranged at a short distance second leg 64 sits with the eye 66 on the Ring bead 58 of the control part 50 and lies with both Legs 62, 64 on both sides of its grooved pin 56.

An elongated loading lever 70 is shown in FIGS. 7 and 8, with a front section that has a handle 71 forms from the bottom to save weight hollowed out, and a rear section that is close its rear end is a longitudinally extending one Has loading lever slot 74.

The loading lever slot 74 has such a width that it can be easily moved on the axis 18. Furthermore the rear section has two stepped edges in the shape of a circular arc, which matches the top end edge 15 and lower end edge 17 of the cover plate 16 are formed. As a result, the loading lever 70 is engaged by it Edges and the front edges 15, 17 over a predetermined Angular range rotatably guided. This angular range will exceeded when the loading lever 70 90 ° to the left (in the top view) is pivoted. Then he can along his Elongated hole 74 to be moved backwards.

On its underside, the loading lever 70 has the rear End of the handle two opposite lugs 72 on. In front of these lugs 72 is a protruding downward in the middle Loading lever pin 76 attached. One of the noses 72 is in the assembled state the protruding downwards Section of the locking pin 46 of the locking lever 40 opposite. The loading lever pin 76 engages in front of the grooved pin 56 of the Control part 50 between the two legs 62, 64 of the Double leg spring 60 a (see Fig. 2).

On each of the side edges of the loading lever 70 in front and behind the loading lever slot 74 is a front stop 78 and a rear counter-stop 79 is formed.

When assembled, the axle 18 is in the loading lever bracket 14 struck, and the double leg spring 60, the Control part 50, the slider 30, the locking lever 40 and the Loading lever 70 onto axle 18 in the order mentioned put on. To do this, if necessary, the force of the compression spring Switch off 20 is in the bottom of the loading lever bracket 14 a hole is formed for inserting a tool, with which the compression spring 20 or the slide 30th can be withheld.

The loading lever mechanism now takes the one in FIGS. 1 and 2 shown arrangement.

The loading lever mechanism is in the position shown Operation from the left, i.e. with the left hand of the Protect, set up. But are the slider 30 and the locking lever 40 with the bottom facing upward mounted, then the loading lever mechanism for operation from the right, i.e. with the right hand of the Protect, set up. A gunsmith or gunman can therefore be equipped with the loading lever mechanism Gun to a right or left-handed shooter individually to adjust.

It will now be shown with reference to that in FIGS. 9a to 9e Operating positions of the loading lever 70 and the occurring functional processes explained. 9a to 9e is the top view of the loading lever mechanism shown, the handle 71 of the loading lever 70 and the Closure part 10 are visible; whose cover plate is 16 not shown for the sake of simplicity.

Figure 9a shows the loading lever mechanism in the rest position is also shown in Figures 1 and 2; the loading lever is 70 aligned to the longitudinal direction of the weapon. Here is the Loading lever mechanism from above and below through other weapon parts covered, over which it does not survive laterally. In the rest position, the two legs 62 and 64 of the double leg spring 60 the loading lever 70 in its Longitudinal alignment.

If the shooter wants to load the gun, he presses with the finger horizontally from the left side against the Handle 71 of the loading lever 70 (arrow in Fig. 9b) and pivoted this a little as shown in Fig. 9b. Here presses the nose 72 of the loading lever 70 against the locking pin 46 of the locking lever 40 and pivots this against the Force of the bending leg 22 of the compression spring 20 on the Spring pin 42 acts until the locking pin 46 out of the locking recess 36 of the slider 30 is pushed out and this is no longer supported from the front. Well now the slide 30 moves due to the force of the compression spring 20 move forward, with the moving forward Bolt 34, which engages in the notch 54 of the control part 50, this pivoted counterclockwise. Of the Grooved pin 56 of the control part 50 takes at his Pivotal movement of the second leg 64 of the double leg spring 60 with. At the same time, when the handle is released the locking pin 46 of the locking lever 40 is released, which is pivoted back by the bending leg 22 until the locking pin 46 against the contact edge 37 of the slide 30 is present, which is now even after has moved forward.

If the handle 71 is now released, then it becomes and so that the loading lever 70 through the first leg 62 of the Double leg spring 60, which against the loading lever pin 76 abuts by approximately 45 ° counterclockwise to the outside pivoted (Fig. 9c), so that the handle 71 now from the Gun protrudes sideways and effortlessly gripped by the shooter can be.

When loading, the shooter pulls the handle 71 back until it protrudes from the weapon at right angles (Fig. 9d). The stop 78 of the loading lever 70 comes to System against the engagement lugs 35 of the slide 30 and presses it back against the force of the compression spring 20. Whose contact edge 37 moves under the Locking pin 46 of the locking lever 40 to the rear, so that he can jump to his starting position. The attack of the spring pin 42 against the side edge of the recess 33 the slider 30 limits this backward movement of the Locking lever 40 and ensures that the locking pin 46th is located exactly in front of the recess 36. The plant of the Stop 78 against formation of the closure part 10 or the cover plate 16 limits the pivoting movement of the Loading lever 70.

With the backward movement of the slider 30, this takes about the engagement of its bolt 34 in the notch 54 of the Control part 50 with this and swings it back, whereby the grooved pin 56 the first leg 62 of the double leg spring 60 takes along, so that the two legs 62, 64th be stretched apart and the second leg 64 den Loading lever 70 loaded via its loading lever pin 76.

If the handle 71 is now released, then this gives the Engagement lugs 35 free, so that the slide 30 after moved forward until the locking pin 46 in the locking recess 36 sits on. The second leg 64 pivots the loading lever 70 back to its rest position (Fig. 9a).

If on the closure (closure part 10) one forward directed force should be exerted, for example in the case of a Faulty loading, then the side is fully swung out Handle 71 pressed towards the center (arrow in Fig. 9e). The loading lever 70 moves in its longitudinal direction over the length of the loading lever slot enabled distance, the counter stop 79 of the Loading lever 70 on the stop 78 opposite Side of the middle a complementary training on the closure part 10 or engages behind the cover plate 16. Of the Loading lever 70 is now on both sides of the middle from behind supported and thus rigidly connected to the closure member 10. By pulling the loading lever 70 against the 9e, the loading lever 70 closes again its pivoting movement is released and works like described above.

The loading lever 70 is located in that shown in Fig. 9a Rest position and it is not from the left, but from the right tapped here, then there is no reaction and he remains in its rest position.

In contrast, as already described above, the slide 30 and the locking lever 40 compared to that in the drawing shown position so that the bottom each points upwards, then touch (Fig. 9b) and the pivoting (Fig. 9c, 9d) from or to the right. The The loading lever (Fig. 9e) is locked in by pushing it in the loading lever 70 from right to left.
