Description

The invention relates to a barrel barrel weapon for hunting purposes with devices for closing, locking and reopening the breech, for igniting a cartridge in the cartridge chamber and for removing cartridges and ejecting the sleeves.

Drop barrel weapons with the facilities mentioned are known per se. The device for closing, locking and reopening the breech regularly has a barrel hook and a hinge pin arranged in the breech piece, around which the rifle barrel can be tilted. A second barrel hook on the gun barrel is provided with a locking catch for the engagement of a spring-loaded, slidably guided and manually operated bolt. The main elements of

The device for igniting a cartridge in the chamber is the trigger device with bolt, trigger sheet, trigger pin and trigger spring and an impact piece that can be rotated about an axle bolt, while the device for pulling cartridges and for ejecting the sleeves includes an extractor pin that can be moved within the range of the cartridge chamber and one provides for an actuating element engaging the extractor pin when the barrel tilts and thus when the weapon lock is opened. It is essential that all of the above-mentioned facilities are at least partially structurally related and in a complete functional context. It is now known that the longitudinal forces occurring in the locked state of the weapon breech during the shot are absorbed exclusively via the first barrel hook by the hinge pin and introduced into the breech block, while the locking exclusively involves the pickup by the lever between the axis of the cartridge chamber and the axis of the hinge pin occurring tilting moment is used. In the case of the so-called double hook locking, the first hook on the hinge pin also has a locking catch on the back for the entry of a further bolt.

As a result of the stresses on the shot and the tipping of the barrels during loading and unloading, wear and tear occurs over time between the hinge pin and the associated, circular-shaped recess at the front end of the first hook, which loosens the breech or the end of the barrel from the butt of the breech block can take off.

Another disadvantage can be seen in the fact that the bolt is generally actuated by a rotary lever on the upper side of the closure piece, which acts on a slide having the bolt via a shaft and a lever. This is also a considerable additional effort.

In the known break-barrel weapons, the axis pin of the trigger is also mounted on a trigger plate which extends from the breech on its underside to the rear. The axle pin penetrates the trigger blade above the trigger ice, so that when the trigger is pulled, the free end of the trigger blade pushes upward against the actuating end of a rod which is mounted essentially parallel to the trigger blade and is under spring action. Thereupon the latching end of this rod, which is mounted as a rocker, disengages downward from the latching catch of the striking piece, such that the striking piece can hit a firing pin which is displaceably mounted in the butt plate of the striker under the action of its striking spring. In the case of a so-called return lock, the striker then springs back into a so-called safety position, in which the locking end of the rod can snap into a safety catch on the striker.

This known use of a trigger rod, which is arranged essentially parallel to the trigger blade, makes it necessary for the entire trigger device to extend relatively far to the rear toward the barrel of the tipping weapon, ie to build a relatively long one. Due to the position of the trigger rod mentioned, its latching end is always on the underside of the striker or the nut. Since you want to avoid making the trigger blade as long as the entire trigger rod, which would lead to unfavorable leverage, the trigger pin of the trigger must be further away from the butt plate of the barrel barrel than the pivot pin of the hammer. It is also to be regarded as a disadvantage that the trigger blade has to slide at the actuating end of the trigger rod when the trigger is removed, and thus the existing static friction between

Trigger blade and trigger rod must be overcome, which is detrimental to the directness of the trigger or its so-called «dryness». For this reason, in the known device, a so-called engraver is generally used, which ensures the sudden actuation of the trigger rod when pulling off. However, this engraver represents a further, additional effort.

Ultimately, in the case of drop barrel weapons on the forearm, thrust pieces guided in a circular arc are known, which are supported on opening the breech and thus when the barrel tilts at the front end of the breech piece and move upwards on a circular path on the forearm and thereby take the extractor pin with them in such a way that the cartridge is inserted short piece is pushed out of the cartridge chamber and can be easily gripped by hand for unloading. An additional ejector is provided for ejecting cartridges that have been fired.This ejector is also installed in the fore-end of so-called self-tensioners, in which the lock is tensioned by tipping the barrels using so-called tension levers, which on the one hand engage the forearm and on the other hand on the striking parts of the lock . If, for example, the two locks are released when a double shotgun of this type is fired, then when the barrel is subsequently tilted to remove the sleeves of the shot cartridges, not only is the locking of the locks mentioned by pivoting the tension rods on the part of the forearm, but also the triggering of the two striking pieces of two ejectors, which are locked under spring pressure and are in the forearm and which strike against the opposite end of the two extractor pins which are present on a double-barreled weapon. When the weapon is closed, the extractor pins are then pushed in again through the butt plate of the breech block, pushing the striking pieces or hammers of the ejector back into the cocking position.

The object of the invention is now to provide a barrel-barrel weapon with the devices mentioned at the outset, which is simple and has a small number of components, is space-saving and has good long-term functionality.

This object is achieved in that, in the closed position of the closure, the front barrel hook is at a distance from the hinge pin, while the rear barrel hook with a correspondingly beveled surface rests on a surface on the crosspiece of the closure piece and has a locking catch which, together with the bolt each is formed essentially> the same wedge angle, and above the rear hook, which is provided with two coaxial and spaced sections with an intermediate compression spring extractor pin, at the front end of which an actuating element engages, and that the trigger blade is rotatable about an axle pin , which is arranged closer to the butt plate of the locking piece than the axle base of the striking piece, the clamping latch of which rests in the clamping position on the latching end of the web extending upward from the trigger sheet.

In an embodiment of the invention, the crosspiece and the rear barrel hook can each have a load cross-section such that at least the longitudinal forces that occur when the shot is fired are absorbed.

With this configuration, clear load-bearing ratios are achieved, without additional, complex locking devices, in particular the longitudinal forces occurring during the shot are picked up exclusively by the second barrel and the crosspiece of the closure piece. Shear forces, insofar as they occur due to the tilting moment, as a result of the lever arm between the longitudinal axis of the barrel or the cartridge chamber and the crossbar, are absorbed by the single bolt. The hinge pin does not transmit any forces when the weapon breech is in the closed position, not even during firing. It is used exclusively in connection with the front barrel hook as a pivot bearing when the barrel is tipped over for loading or unloading the same.

When the barrel tilts, it shifts by the existing distance between the hinge pin and the associated barrel hook on the hinge pin until it comes to rest between these two parts. A change in the fit between the barrel end and the butt plate of the weapon lock, due to wear of the relatively difficult to match surfaces, between the hinge pin and the circular recess of the associated barrel hook cannot occur. On the other hand, the flat, adjacent surfaces, on the one hand of the crosspiece and on the other hand of the rear barrel, can be machined more easily and precisely, so that a perfect, flat contact of these two parts can be guaranteed, which prevents plastic deformation during the use of the weapon; quite apart from the fact that there is hardly any friction between these two surfaces. Otherwise, a barely noticeable game would already be automatically eliminated by the fact that the barrel hook moves slightly further downward into the closure piece, as a result of which both this game and any game that may occur between the end of the barrel and the pushing floor 30 would be eliminated . A self-adjustment would thus take place, so to speak.

The device according to the invention no longer requires a rod. Rather, the trigger element itself with its upwardly extending web engages in the catches of the striker or the nut.

This and the arrangement of the axle pin according to the invention result in very favorable lever ratios which ensure a direct and dry trigger. The special arrangement of the axle pin, in the area of the 40 angle formed by the trigger blade and the web, also makes it possible to move the tongue further forward, practically under the locking piece, as is the lack of a rod that extends horizontally backwards away from the striking piece contributes to the fact that the device 45 is very short and takes up little space behind the breech towards the barrel of the weapon. An engraver is no longer required.

The axis pin of the trigger is expediently arranged in the area of the web adjoining the trigger sheet, so that the web is shortened as the load arm of the lever, while the trigger sheet with the tongue as the arm of the lever can be designed to be relatively long, which, according to the lever laws, leads to a particular problem easy trigger pull.

55 The extractor pin according to the invention, with the relatively hard compression spring in between, behaves when loading and unloading a sharp cartridge in the same way as a conventional, one-piece extractor pin, that is to say, when the barrel tilts, the actuating element 60 transmits the extension movement of the adjacent section of the extractor pin via the compression spring onto the section of the extractor pin which is in contact with the cartridge, without being compressed, since the sharp cartridge has a certain clearance 65 within its cartridge chamber and can be pushed out of the cartridge chamber with practically no resistance. However, if the cartridge has now been fired, the explosion pressure has deformed the cartridge case consisting of a brass alloy in such a way

5

that it is pressed against the wall of the cartridge chamber and opposes the pushing out a considerable resistance, which is caused by the existing static friction between the outer wall of the cartridge case and the wall of the cartridge chamber.

It follows from this that the ejection movement of the adjoining section, which inevitably takes place due to the actuating element when the barrel tilts, does not initially lead to a movement of the section resting on the cartridge case or at its edge, but rather to compression of the compression spring. The spring force thus built up rises to a value which is sufficient to overcome the static friction between the cartridge case and the cartridge chamber, whereupon the empty cartridge case is suddenly ejected by the spring force, since the portion engaging on the cartridge case is abruptly pushed into its maximum extension position by the spring is moved, which leads to a considerable acceleration of the sleeve, which is thus ejected in a high arc.

Preferably, the bevelling of the two surfaces of the crossbar on the one hand and the rear barrel hook on the other hand is equal to or smaller than the respective self-locking angle, so that the static friction occurring during the shot would theoretically be sufficient to prevent the barrel from tipping over as a result of the tilting moment.

However, it is to be understood that the existing lock, regardless of the firing of a shot, is already required to absorb lateral forces which otherwise act on the barrel and which could lead to it tipping, e.g. Impact, impact, acceleration forces or the like. A further, expedient embodiment of the device according to the invention also serves for a good absorption of the tilting moment, according to which the distance of the hinge pin from the butt plate is a multiple of the distance of the transverse web from the butt plate. This requires a long design of the closure piece and thus a relatively long length of the contact surface of the barrel on the closure piece in the longitudinal direction.

The latch is preferably a locking wedge, the wedge height measured in the direction of displacement running between its two wedge surfaces and the lower wedge surface rising slightly towards the second hook, while the upper wedge surface is inclined strongly downwards and in the closed position a small distance from the opposite wedge surface of the locking catch of the assigned associated hook. This design favors an automatic readjustment of the locking fits, since the locking wedge can slide a little deeper into the locking catch when the barrel hook sits deeper on the crossbar until it rests against the lower, slightly inclined wedge surface of the locking catch.

According to a preferred embodiment, the wedge is arranged on a locking slide which has the trigger guard and is displaceably mounted back and forth, essentially parallel to the running axis in the locking direction and unlocking direction, on the underside of the locking piece against the pressure of a spring. This locking slide is formed in one piece and is slidable at its front end, between the bottom of the locking piece and the underside of the crosspiece, at its rear end on the axle pin of the trigger located transversely in the locking piece, and with its central area having the wedge on the underside of the butt plate guided. This version enables a very simple and direct opening and closing of the weapon breech, without turning and pivoting additional parts by simply moving the trigger guard towards the barrel of the barrel barrel weapon, whereupon the barrel can tip over, and by swiveling the barrel end in and snapping it back into place Lock wedge in the locking catch of the rear hook under spring pressure on the other hand.

The safety catch is advantageously in the safety position and the clamping catch in the cocking position of the trigger at the height of the axle bolt of the striking piece between the striker and the locking piece or the butt plate. Of course, this means that the web of the trigger must also be located in this area between the axle pin of the striking piece and the butt plate, in a region that has not previously been used to actuate the trigger.

The safety catch on the striking piece and the catch end of the web are preferably stepped in a step-like manner, the catch end engaging behind the safety catch. This ensures that no trigger actuation can take place at all in the safety catch, in which the striking piece is raised from the firing pin or firing pin of the weapon, but rather the striking piece and the trigger lock each other. This locking can only be released by actuating the striker by means of a tap or the like and then actuating the trigger.

According to a particularly preferred embodiment of the invention, in the clamping position, the surface of the clamping latch resting on the latching end of the web is inclined towards the axle bolt such that this surface is inclined upwards from the latching end of the web in the direction of movement of the web when it is pulled off backs away. This favors easy and dry peeling. Such pulling off is further favored by the fact that the latching end of the web can be offset relative to the thrust floor, with respect to the axis pin of the trigger, such that the line of action of the force exerted by the tension spring on the web via the tensioning latch is at a lever distance from the axle pin runs. With this arrangement, the trigger is already biased in the trigger sense. Only the static friction between the catch end and the catch stop prevents the shot from breaking. Thus, without the need for an engraver, all that is required is a slight pressure on the tongue to allow the snap end to snap forward and the striking piece to be knocked off.

In a preferred embodiment of the invention, an equally displaceable spacer for limiting the relative movement of the same is arranged between the two sections of the extractor pin. It is also advisable not to polish the cartridge chamber. The fact that one does not polish the wall of the cartridge chamber favors the occurrence of sufficient frictional adhesion between the outer wall of the fired cartridge case and the cartridge chamber even when oil residues are present. The spacer ensures that the ejection process is initiated by mechanical loosening at the appropriate moment. Without the spacer, a sleeve that was too tight would not be ejected and a sleeve that was too light would be ejected too early, so that the sleeve would be thrown against the lock case before it was fully opened. The tension of the sleeve in the bearing must always be greater than the compression pressure of the injector spring. The spacer reduces the resistance of the sleeve in the bearing to such an extent that the compression force predominates and relaxation is initiated.

Another advantage is the low noise level of the weapon according to the invention, since it dispenses with an impact piece for actuating the extractor pin when the empty cartridge case is ejected.

Preferred developments of the invention are the subject of the above claims.

The invention and its advantageous embodiments are explained in more detail below with reference to an embodiment shown in the drawing.

Fig. 7 is a side view of the trigger used in the embodiment shown;

Fig. 9 is a plan view of the rocker forming the actuator.

In Figures 1 to 3, a break barrel weapon is shown, which is a single-barrel hunting rifle. For the sake of clarity, the essential part of the barrel and the free end of barrel 1 have been omitted for this barrel barrel weapon. The barrel 1 is pivotable by means of a front barrel hook 2 and a hinge pin 4 arranged in the closure piece 3 and has a rear barrel hook 5 which has a locking catch 6 for the engagement of a spring-loaded, displaceably guided and manually operated bolt 7 on the closure piece 3. The front hook 2 engages with a semicircular recess 8 on the hinge pin 4, while the rear hook 5 engages with its locking surface 9 on a crosspiece 10 of the closure piece 3.

Between this crosspiece 10 and the butt 11 of the closure piece 3, an opening 12 (see also Fig. 4) for the engagement of the rear barrel hook 5 is provided. There is also a trigger device with a trigger 13, a trigger blade 14, an axle pin 15 and a trigger spring 16.

Furthermore, an impact piece 18 loaded by a striking spring 17 is rotatably mounted with a cock 19 about an axle bolt 22 mounted in the closure piece 3, specifically in the cheek-like extensions 20 and 21 of the same (FIG. 4). The striker 18 has a safety catch 23 and a clamping catch 24.

According to the invention, the mutually facing surfaces 9 and 25 on the one hand of the rear hook 5 and others. on the side of the crossbar 10 beveled in the same direction and lie against each other in the closed position of the weapon lock. 1 also shows the angle a of the two surfaces 9 and 25, which illustrates the bevel, in relation to a plane perpendicular to the running core. As can also be seen, the barrel hook 2 assigned to the hinge pin 4 is at a distance “a” from it in the closed position (FIGS. 1 and 2). The crosspiece 10 and the rear barrel hook 5 have such a load cross-section that they can at least absorb the longitudinal forces occurring during the shot. Finally, both the bolt 7 and the locking catch 6 are wedge-shaped, each having an essentially identical wedge angle β.

The beveling of the two surfaces 9 and 25 of the hook 5 and the crossbar 10, corresponding to the angle α, 5 is expediently equal to or smaller than the respective self-locking angle, taking into account the coefficient of friction between the two surfaces 9 and 25.

The distance of the hinge pin 4 from the butt plate 11 in the embodiment shown is a multiple of the distance of the crosspiece 10 from the butt plate 11.

The wedge height "h", measured in the direction of displacement according to double arrow A (FIG. 2), of the bolt designed as a locking wedge runs between its two wedge surfaces 27 and 28, the lower wedge surface 27 rising slightly towards the rear barrel hook 5, while the upper one Wedge surface 28 is inclined sharply downward and in the closed position (FIGS. 1 and 2) has a small distance from the opposite wedge surface 29 of the locking catch 6 of the associated hook 5. The lower wedge surface 27 thus bears against the opposite surface (FIG. 2) of the barrel hook 5. This configuration also serves to automatically adjust the fit between the end face 30 of the running end 31 and the face of the butt plate 11, since the bolt 7 under the action of the spring 16 hooks the barrel 5 25 and thus the barrel 1 in cooperation with the surfaces 9 and 25 loaded in the direction of arrow B (Fig. 1) to the bottom 32 of the closure piece 3.

In the embodiment shown, the bolt 7 is arranged in the locking direction on a locking slide 34 which is displaceable to and fro essentially parallel to the longitudinal direction of the locking piece 3 in the direction of arrow A. In the unlocking direction, the bolt 7 is arranged on the locking slide 34 35 which is mounted on the underside of the locking piece 3 and has the trigger guard 33. This locking slide 34 is formed in one piece and at its front end 35 between the locking piece base 32 and the underside 36 of the crossbar 10, at its rear end 37 on the axle pin 15 40 of the trigger which is seated transversely in the locking piece 3 or its cheeks 20 and 21 and with its middle region 38, which has the bolt 7, is slidably guided on the underside 39 of the butt plate 11.

The helical compression spring 16 engages on the one hand on a rear contact surface 40 of the central region 38 of the 45 slide slide 34 as a locking spring and on the other hand somewhat above the axle pin 15 on an essentially vertically extending web 41 of the trigger 13 as a trigger spring. The two ends of the spring 16 are expediently recessed into the indentations of the central region 38 and the web 41 indicated by dashed lines.

As can be seen from FIG. 3, the striker 18 arranged above the rear end 37 of the locking slide 34 and the trigger 13 has an extension 42 which can be brought into contact with a rear stop surface 55 43 of the locking slide 34 when tensioned and the locking slide 34 against an opening of the weapon lock locked.

The striking of the striking piece 18, according to FIG. 3, is done by pulling it back by means of the tap 60 19 until, under the action of the spring 16, the latching end 44 of the web 41 engages under the straining latch 24 of the striking piece 18. A variable locking stop in the form of a self-locking grub screw 45, which can be rotated in the striking piece 18 below the tensioning latch 24 and thus adjustable, allows the distance which the latching end 44 of the web 41 of the trigger 13 moves under the tensioning latch 24 of the striker to be adjusted 18 can cover. This is done to regulate the trigger ratio on the shot, being the same

it is ensured at an early stage by the attachment 42 that the closure cannot open before and when the shot is fired, since the closure slide 34 remains locked via the stop surface 43, the attachment 42, the locking catch 24, the locking end 44 and the axle pin 15.

If, on the other hand, the shot has been fired and the striker 18 is in the knocked-off position, as shown in FIG. 1, the web 41 of the trigger 13, which has the latching end 44, is in a forward inclined position between the striker 18 and the rear side 46 of the butt plate 11 pivoting about the axis pin 15 essentially locked. At the same time, a shoulder 47 provided on the web 41 is pivoted from above into a recess 49 of the locking slide 34 provided with a stop 48 for abutment against this stop 48, such that the locking slide 34 also in this position of the hammer 18 against opening of the weapon lock is locked.

In addition to FIG. 1, reference is also made to FIGS. 6 to 8. This configuration prevents a sharp cartridge from possibly being loaded into the weapon and then being closed in the system shown in FIG. 1 of the striking element 18 on the rear side 46 of the butt plate 11 and thus at the same time in the pushed-out position of the firing pin, which is then closed, since in In this case, when the barrel gun is closed, the cartridge can be ignited and the shot could break, since the firing pin or firing pin, not shown, could not deflect towards the striker under the pressure of the cartridge primer.

Of particular advantage is the fact that the closure slide 34 with the trigger 13 inserted and the closure or trigger spring 16 after the axle pin 15 has been pushed out of the cheeks 20, 21 of the closure piece 3 can be swung down without the need to loosen screws . It should be pointed out that the device according to the invention, if one disregards the purposes other than fastening screw 45, does not require a single screw in order to be assembled and disassembled properly and to function properly and safely. Drop barrel weapons according to the invention have already proven themselves in practice.

In the area of the cartridge chamber 26 on the underside of the barrel 1, an extractor pin according to the invention consisting of two substantially coaxial and spaced sections 50 and 51 is provided, which is mounted in a longitudinal bore 52 so as to be displaceable to a limited extent. The limit in the form of a stop is formed by a cross pin 53 mounted on the barrel 1, which engages in a longitudinal groove 54 of the section 51. The section 51 of the extractor pin also has at its end facing the butt plate 11 of the closure piece 3 an edge which engages under the cartridge bottom of the cartridge 56 located in the cartridge chamber 26 and indicated by dash-dotted lines. The second section 50 has another end 57 for the engagement of an actuating element 58. Between the two sections 50, 51 there is also a compression spring 59 which can be tensioned towards one another at the two opposite ends of the two sections 50, 51.

In the preferred embodiment shown, a likewise displaceable spacer 60 is arranged between the two sections 50, 51 to limit the relative movement of the sections 50, 51 towards one another. This spacer 60 is advantageously a substantially concentrically arranged, pin-shaped projection which is firmly connected to the section 50, the compression spring 59 being a helical spring seated on the projection.

The actuating element 58 is a rocker arm in the form of an angle lever which can be pivoted about an axis pin 61 arranged on the underside of the gun barrel 1, in the area of the angle lever at a longitudinal distance from the hinge pin 4 of the locking piece 3, and the angle bar 62 facing the barrel 1 when the barrel 1 tilts (see FIG. 2) acts on the second section 50 or on the end 57 thereof, while the angle lever engages with its angled web 63 facing the closure piece 3 on a stationary transverse pin 64 of the closure piece 3. For this purpose, the angled web 63 facing the closure piece 3 has at its end a claw 65 which rotatably encompasses the transverse pin 64 and by means of which the rocker arm or the actuating element 58 can be suspended on the closure piece 3. The free end of the claw 65 extends around the cross pin 64, back so far parallel to the adjacent area of the angled web 63 that the claw 65 can be displaced relative to the cross pin 64, remaining in contact with the same.

Furthermore, it is advantageous that the area of the claw 65 of the angled web 63 facing the locking piece 3 is angled upwards towards the extractor pin relative to the area of this angled web 63 surrounding the axial pin 61 and widened in the transverse direction. At the same time, the claw 65 has on its upper side adjacent to the barrel 1 a longitudinally extending recess 66 for receiving the adjacent region of the barrel 1 receiving the sections 50, 51 of the extractor pin in the bore 52 when the weapon lock is closed (FIG. 1 ). on.

In the embodiment shown, the area of the front hook 2 remote from the hinge pin 4 is also at least partially forked in its longitudinal center plane to form two spaced-apart webs, which are perpendicular to the plane of the drawing and hold the axle pin 61, only the one in FIG Drawing rear web 67 is indicated, while the front web has been cut away to make the mounting of the bell crank clearer. This angle lever or the actuating element 58 is namely pivotally mounted between the webs on the axle pin 61.

It can easily be seen that when the weapon breech is opened from the closed position shown in FIG. 1 to the open position shown in FIG. 2, the axis pin 61 pivots in a circular path around the hinge pin 4. It can also be seen that when the weapon lock is closed, according to FIG. 1, the axis pin 61 is at a vertical distance below an imaginary plane in which the central axes of the hinge pin 4 and the transverse pin 64 are located. For this reason, during the pivoting or tipping of the barrel into the open closed position, according to FIG. 2, in which the axle pin 61 is located at a vertical distance above the imaginary plane mentioned, the claw 65 moves back and forth along the Cross pin 64. At least in the open position shown in FIG. 2, the cross pin 64 is in contact with the base of the claw 65, so that the barrel 1 cannot be pivoted open or tilted further.

During the movement described, pivoting of the actuating element 58 or of the angle lever takes place at the same time, of course, in such a way that the angle surface 68 of the angle web 62 facing the barrel 1 of the second section 50 of the extractor pin comes to rest and pushes it out (FIG. 2). The sharp cartridge 56 shown is pulled out of the cartridge chamber 26 and is therefore easy for the user when unloading the rifle

tangible. The helical compression spring 59 is not compressed since the sharp cartridge offers practically no resistance to being pushed out.

The situation is different if the cartridge 56 was fired with the closure closed, as shown in FIG. 1.

If the barrel 1 is subsequently tilted into the position shown in FIG. 2 by opening the closure, it results that the first section 51 of the extractor pin could not follow the forced movement of the second section 50.

As a result of the explosion pressure, the wall of the cartridge case has undergone such an expansion that it is now stuck in a kind of press fit in the cartridge chamber 26. The spring 59 is inevitably compressed until the spacer 60 in the form of the pin-shaped projection comes to rest on the opposite end of the first section 51 of the extractor pin. Each further movement of the section 50, under the influence of the actuating element 58, leads to an abrupt release of the sleeve of the cartridge 56 which is stuck in the cartridge chamber 26 and is then suddenly ejected.

It should be emphasized here that not only the usually slightly conical shape of the cartridge cases favors this function, but also the fact that the cartridge chamber 26 does not need to be polished. It goes without saying that a certain, relatively slight roughness in the surface of the cartridge chamber 26 prevents the formation of Stiction between the sleeve of a shot cartridge and the wall of the chamber 26 favors. This static friction is suddenly released in the manner mentioned when the spacer 60 strikes the first section 51 of the extractor pin.

The return of the two sections 50 and 51 takes place when the weapon breech is closed by swiveling in the running end 31, the shoulder of the first section 51 being pushed in again along the surface 69 of the butt plate 11. This movement is passed on to the second section 50 via the spring 59, the movement of which is released by the pivoting back of the actuating element 58.

As one can easily imagine, when the weapon breech is closed, the bolt 7 of the slide slide 34 is pushed back by the rounding 70 of the rear hook 5 against the force of the breech spring 16 which simultaneously forms the trigger spring, until the bolt 7 under the action of this Spring 16 can snap back into the catch 6 on the hook 5.

The trigger blade 14 has an upwardly extending web 41, on the latching end 44 of which the clamping latch 24 of the striking element 18 rests in the clamping position. Furthermore, the axle pin 15 is arranged in the region of the angle formed by the trigger blade 14 and by the web 41 and closer to the plane of the butt plate 11 of the closure piece 3 than the axle pin 22 of the striking piece 18.

In the preferred embodiment shown, the axle pin 15 is arranged in the region of the web 41 adjoining the trigger sheet 14. This arrangement not only provides a more favorable leverage for the trigger, as mentioned at the beginning, but also a favorable possibility for arranging the axis pin 15 in the material of the closure piece 3.

The safety catch 23 is preferably in the safety position and the clamping catch 24 in the clamping position of the trigger device approximately at the height of the axle pin 22 of the striking element 18 between the striking element 18 and the butt plate 11 of the closing element 3.

This ensures optimal use of the space available in this area.

In the embodiment shown, the safety margins

8th

Most 23 on the striking piece 18 and the latching end on the web 41 are stepped in accordance with one another in a stepped manner, such that the latching end 44 engages behind the safety latch 23. An actuation of the tongue 13 is not possible in this safety position. Even if the tap is withdrawn by a certain angular amount, it falls back into the locking position when released, without the striking piece 18 falling on the striking pin 11 (not explained in more detail) arranged in the butt plate 11 and the cartridge being able to ignite io 56.

In the clamping position, the surface of the clamping latch 24 resting on the latching end 44 of the web 41 is inclined towards the axle bolt 22 in such a way that this surface is inclined upwards from the latching end 44 of the web 15 in the direction of movement of the web when it is pulled off backs away. Since the latching end 44 moves in a circular path around the axis pin 15 and this movement is initially tangential,

takes place while overcoming the static friction, the surface 24 moves back to the free end of the clamping catch, so to speak 20, so that the rotation of the striking element 18 can already start while the catch 24 still covers the catch end 44. It is assumed that there is even a certain acceleration of the disengaging movement of the latching end 44 on the part of the latch 24 or its surface as soon as the static friction has been overcome. This means a particularly direct, quick and dry triggering of the trigger device, in contrast to a so-called pulling trigger, in which a sliding movement between the rest and the end of the rest of the trigger, again by reducing the finger pressure on the tongue 13, over a certain movement distance of the trigger Rod, as is present in the prior art, can occur.

In order to obtain a line contact between the latching end 44 and the clamping latch 24 in the weapon according to the invention as far as possible, the edge of the latching end 44 which comes into contact with the clamping latch 24 can be formed with sharp edges in order to support the occurrence of the static friction required in the cocked position. It should be emphasized that the 40 slope of surface 24 with respect to the horizontal must of course not be so strong that the angle required for self-locking between the pivoting direction of the web and the inclination of surface 24 would be exceeded, i.e. no static friction could occur.

45 The latching end 44 of the web 41 is preferably offset with respect to the butt plate 11 with respect to the axle pin 15 such that the line of action of the force exerted by the tension spring 17 via the tension latch 24 on the web 41 runs at a lever distance from the axle pin 15 on the reverse. This embodiment places the trigger in the triggering direction under a certain pretension against the force of the trigger spring 16, which is expediently designed as a helical compression spring and, at the same time, represents the locking spring by loading the locking slide 34 in the locking direction 55. In the tensioned position, the closing slide 34 is otherwise locked by a stop provided on the striking element 18. In the safety position shown in FIG. 2, on the other hand, the locking slide 34 can be displaced against the force of the spring 16 in the direction of the shaft (not shown 60) (to the right in the figures), so that the latch 7 can disengage from the rest to the rear to enable the barrel to tip over and thus to load or unload the barrel barrel weapon.

As can be easily seen from the figures, in the embodiment shown, the trigger 13 of the trigger device is arranged essentially below the butt plate 11, which contributes to a compact design of the weapon according to the invention. The length of the trigger sheet

14 as a power arm in the sense of the lever law can be varied in adaptation to the trigger weight desired in each case, on the other hand, a stronger downward movement of the trigger ice 13 due to the greater length of the trigger blade 14 is not aimed at triggering the trigger.

In addition, it is found that it has proven to be expedient in practice to use an angle between the

To use trigger sheet 14 and the web 41, which is substantially 90 °, and the rest of the web 41 in both the safety position (Fig. 2) and in the clamping position (Fig. 3) to be arranged substantially vertically. In particular, the second measure also serves to make particularly good use of space and shorten the overall length in the longitudinal direction of the barrel barrel weapon.
