The invention relates to a folding-barrel, hunting, firearm with devices for closing, locking and reopening the bolt, for priming a cartridge in the cartridge holder and for extracting cartridges as well as for extracting cartridges. eject_the shells.? Firearms with a folding barrel having the aforementioned devices are known per se. arranged in the shutter and around the qu? folding the barrel of the weapon. A second hook on. gun barrel? equipped with a locking stop for the use of a latch. camente-,? guided-sliding on the shutter and? operated.manually. The essential elements of the device for triggering a cartridge in the cartridge holder are the firing device with bolt lock - firing blade -, - pin. shot and_spring of shot_ed. revolving firing pin_ around_a, pemo_axial_, -while the device-. for_extracting_ cartridges and ejecting the - shells foresees an extractor pin, .. which -in the area of the cartridge bridge? the overturning of the barrel and then with the opening of the bolt of the weapon rests on the pin The extractor. Is it essential that all the devices mentioned are between them in a constructive relationship at least partial and complete. And now no_to_the..done_ch.e_l.e

- longitudinal forces that occur in the locked state of the bolt of the weapon during the shot are absorbed exclusively through the first hook of the barrel from the hinge pin and are transmitted in the bolt, while the lock is used exclusively to absorb the riba torque] tament that occurs due to the effect of the lever between the axis of the cartridge holder and the axis of the pin to cer? black. In the nose of the so-called double hook lock of the bed also the first hook of the rod, which rests on the hinged pin, also has a locking stop on its side for the entry of an additional latch.

As a result of the stresses with the shot and the effect of the overturning of the barrels in the nnreo of the narination and of the unloading with the paenare of the time there is a? Wear between the pin in nemi era and the relative recess in the form of an arc of circumference on the extremity. ? front of the first ganeio of the barrel, for which the shutter is loosened mrvpro? 1end? of the barrel can? rise from the bottom of the shutter?

A further drawback consists in the fact that the latch is always operated by means of a revolving lever on the upper side of the shutter, which acts on a slider having the latch by means of a shaft and a lever. There too? represents a considerable expense

In known weapons, with the barrel being tilted, the axial pin of the firing device is also supported on a firing plate which extends backwards from the bolt on its lower side. In particular, the axial pin crosses the firing blade above the trigger, so at the moment of the shot the end? free of the gun blade strike upwards against the extremity actuation of a rod, which is substantially supported parallel to the firing blade and d? subject to elastic charge. Subsequently the extremity? stop of this rod supported as a pivot comes out downwards

such that the firing pin under the action of a percussion spring can? knock on a trigger pin slidably supported in the percussion bottom of the shutter. In a so-called return tightening, the firing pin subsequently returns elastically to a so-called safety position, in which the end? stop of the auction can? penetrate and stop in a safety stop on the firing pin.

This known use of a? Firing rod ,, ciLe? arranged_substantially parallel to the blade -of shot ago..s? necessarily, that the entire firing device extends in a relatively broad manner backwards in the direction of away from the butt of the firearm from the percussion bottom, that is. -Sults of construction - Relatively long. Thanks to the mended position_of the firing rod, the end? stop_of_this_is_ always. on the underside of the percussion or walnut. Since? - it is intended to avoid that the firing blade is made long exactly like the entire firing shaft, which would lead to unfavorable lever conditions, the axial pin should therefore be further spaced from the percussion bottom of the shutter of the 'arma__a canna re? danceable, with respect to the axial pin of the firing pin. A drawback consists in the fact that the blade disappears during the shot. necessarily scroll on the end? of activation of the firing rod and it is necessary to overcome - the existing static friction between the blade or the firing shaft, which is harmful due to the direct action of the firing device or its so-called "dryness". For this reason, in the known device, a so-called trigger is used, which during the

the shot is triggered by the sudden actuation of the firing rod? However, this trigger represents a further additional expense.

Recently, in the years with overturning barrel, translation elements have been known, which are guided in the form of an arc of circumference on the anterior shank. re and with_the_bolt_of the bolt and with the_overturning of the barrel they lean on the extremity? front of the bolt and move upwards on the front shank on a circular trajectory by dragging the extractor pin, so that the cartridge is pushed for a short distance out of the cartridge holder and pu? be .lably. grabbed manually for downloading? For the spooling of shells-fired cartridges? planned

in the front shank of so-called magazines; in which the obturator is loaded by overturning the barrel by means of said loading levers, which on one side actuate. - they come out on the anterior-stem and on the other_side_on the and.

shutter strikers? When to -pio in the course of firing-a double-barreled-gun - from this-mode? both shutters are discharged, then with the subsequent tilting of the barrel in order to remove the solos of the fired cartridges, the aforementioned loading of the shutters does not only take place by means of the orientation of the loading rods from the side of the shank. but at the same time the release of the two striker elements by two ejectors, which are arrested when loaded under elastic pressure, are located in the front leg and strike against the extremity. opposite of? 1and two extractor pins provided in a * sleeping harness? With the closure of the weapon, the extractor pins are then inserted again through the bottom of the shutter percussion, where they abut the_ elements_ of the strikers and / or hammers of the ejectors, again in the loading position. to realize a -? - folding barrel weapon, having the devices mentioned at the beginning. functioning - permanently good. * -,

This problem is solved according to the invention by the fact that in the closed position of the bolt the front hook of the barrel has a distance from the hinge pin, while the rear hook of the barrel with the surface, correspondingly beveled, rests be! between? versino of the shutter and_has a_ locking_ stop-, which together with the latch? carried out with respectively substantially equal opening angle, and above the rear hook of the channel? provided for the plug of the extractor, which? it consists of two partial elements arranged coaxially and mutually spaced, with an interposed proximity spring, and on whose extremity? an actuation element acts, and furthermore due to the fact that the firing blade is rotatable about one. axial plug what_? disposed..on._bottom _of or in_of the shutter pi? near the axial bottom of the firing pin, the loading stop of which in the loading position rests on the end stop of the crossbar which extends upwards from the firing blade

In carrying out the invention, the traver and the rear hook of the barrel can respectively have one such cross section. loading rooms that are absorbed - at least the longitudinal -zes that appear during the shot - Thanks to this execution, by doing without additional and expensive - locking devices -, univocal conditions of - absorption are obtained. -to -del - load-, where especially the - longitudinal forces - which occur at the moment of the shot come as? -sorbed-exclusively by the second hook of the can-L na-and-the shutter crossbar? The-forces between? -sversal-i-, if produced by the overturning torque as a consequence of the lever arm between the longitudinal axis of the barrel or the cartridge holder: and the crosspiece, they are absorbed by the single key. .vistell_o. The hinge pin transmits no force into the bolt-hinged position for the firearm, nor when shooting. It_in com_. The combination with the front hook of the barrel serves exclusively as a rotation bearing in the course of the overturning of the barrel. barrel for the purpose of loading. or download the same? _ _

With the overturning of the barrel, it moves according to the distance between the hinge pin and the associated hook of the barrel on the hinge shaft until it rests between these two parts. Can't there be a variation of the ac? coppiamenio between the extremity? of the barrel and the percussion bottom of the bolt of the weapon - as a consequence of the wear of the surfaces, of relatively difficult adaptation, between the hinge pin and the circular recess of the associated barrel hook? On the other hand, the flat surfaces, leaning one against the other, on one side of the transversal element? RaiR or on the other side of the rear hook of the sleep, can be processed simply and pre oisamente, so that? can you? guarantee a perfect surface support of these two parts, which will prevent plastic formations during the use of the weapon; quite apart from the fact that he can't? there is hardly any friction between these two surfaces. For the rest, a game, barely appreciable -, _ would be automatically deleted

already? due to the fact-that-the hook of-the-c.anna_ moves -lightly further downwards in the shutter, for which it would be eliminated both that also a possible play that occurs between_ -the extremity? of the - barrel and the bottom_of percussion ?. ^ Therefore for what? say would there be a self-correction? - The device according to the invention-does not require more? any auction. On the contrary, the firing element with its own crossbar that extends upwards engages itself in the stops_of the percussion, or rather of the nut?

In this way and as a consequence of the inventive arrangement of the axial pin, very advantageous lever conditions are obtained which guarantee a direct and dry firing. The special arrangement of the_axial_pin_in_zone.

- from the firing blade and from the crosspiece it also allows - to further move - the trigger - in advance practically below the bolt - which, like the lack of a rod, which extends horizontally in sense of distance from the firing pin backwards, contributes to the fact that the device? executed very short and does not occupy his uncle behind the bolt towards the butt of the weapon,> Not? more necessary a pusher <

The axial swine of the firing device? suitably arranged in the area of the cross member bordering the blade. be carried out relatively long, which on the basis of the lever laws contributes to a particularly easy actuation of the firing device.

The extractor plug which according to the invention is divided., __ with__ the interposed_spring_of .__ relatively-hard pressure, during the loading and unloading of a loaded cartridge, behaves in the same way as a convention. onal and pin of or layers; hours - in a single part -, that is the actuation element - during the overturning of the barrel - transmits the movement of use of the supported partial element of the pin of the extractor through the pressure spring on the part_item-. the leaning-to the cartridge-, of the extractor plug, without being compressed, since? the loaded cartridge inside the cartridge holder has a certain play and can? be ejected practically without resistance from the cartridge nortacartridge? However, if you are quick to point 1 to the cartridge? was the p r and s fired? f) has deformed the cartridge case, made of a brass alloy, in such a way that under pressed coupling it rests on the wall of the cartridge holder and opposes a considerable resistance to the ejection, which is caused by the Is there any static friction between the outer wall of the cartridge case and the wall of the cartridge holder?

? - Da_ci? it follows that the ejection movement of the supported partial element which occurs with the overturning of the barrel fuses from par.

of the actuation element, does not lead to a movement of the partial element which rests on the cartridge case - that is, to its edge., but leads to a compression of the pressure spring. -a sufficient value to overcome-the-friction_stati = -co between-the cartridge case and the holder? cia-, after which there is a sudden ejection of the empty case due to the cari-Tastica, since? the partial element acting on the cartridge case by the effect of the spring is moved abruptly into its maximum ejection position, which leads to a considerable acceleration of the cartridge case which is therefore ejected following a high arc.

the bevel of the two edges of the cross member on one side and of the rear hook of the barrel on the other side is equal to or less than the respective spontaneous locking angle. the static friction that occurs in the course of the shot would theoretically already be? sufficient to prevent the barrel from overturning as a consequence of the overturning torque? However, it is understood that the ^ existing block? _Gi? necessary_in a completely independent way from a shot, to absorb and on the other hand lateral forces ^ acting on the barrel which could lead to its overturning, for example forces_ of percussion, __ of impact_, of ac ed eration or similar -? of the overturning mechanism also requires a further suitable execution of the device according to 1 in? vention, -second -which_the_distance of the_group pin-. ra from the percussion background? equal to a multiple of the distance of the crosspiece from the percussion bottom; neither.

In this folding barrel gun for the sake of clarity am I? have been omitted the substantial part of the football and the extremity? free of barrel 1? The barrel 1 by means of a front hook 2 of the barrel and a hinged pin 4, arranged in the shutter 3,? pivoting and has a rear hook 5 of the barrel, it has a block 6 for the engagement of a spring-loaded bolt, slidingly guided on the shutter 3 and operated manually. pp front hook or of the barrel with a recess 8 in the half-round shape acts on the hinge pin 4, while the rear hook 5 of the barrel with its locking surface 9 acts on a crossbar

Between this cross member 10 and the impact base 11 of the shutter 3? foreseen an opening 12 (see also figure 4) for the stop of the gar ci? 5 rear of the barrel. Furthermore ? a firing device with a trigger 13, a firing blade 14, an axial pin 15 and a firing spring 16 is provided.

Also a firing pin 18, loaded by a percussion spring 17, with a hammer 19? rotatably supported about an axial pin 22 which? supported in the shutter 3 and precisely in the adjoining appendages, 20 and 21 and this (figure 4)? Does the firing pin 18 have a safety stop 23 and a loading stop 24?

According to the invention, the surfaces 9 and 25, facing each other, on one side of the hook-rear 5 of the barrel and on the other side of the crosspieces> 10 are beveled in the same direction and in the ohinmira position, of the gun stoppers rest one on top of the other? Figure 1 also shows the angle? , indicating the chamfer, of the two surfaces 9 and 25 with respect to a plane perpendicular to the core of the barrel. Furthermore, how can the hook 2 of the barrel, associated with the hinge pin 4, be detected? in P? closing position (Figures 1 and 2) has a distance "a" from these. The crossbar 10 and hook po

The chamfer of the two surfaces 9 and 25 of the hook 5 of the barrel and of the crosspiece 10, corresponding to the angle? , and suitably equal to or less than the respective automatic locking angle, taking into account the friction coefficient between the two surfaces 9 and 25?

The distance of the hinge pin 4 from the impact bottom 11 in the embodiment shown? a miltiplo of the distance of the crosspiece 10 from the percussion base 11.

The height "h". measured in the direction of displacement according to the double arrow A (Figure 2) of the bolt made in the form of a shutter wedge. extends between its two wedge surfaces 27 and 28, with the lower surface 27 a? falls weakly towards the rear hook 5 of the? the barrel, while the upper surface 28 of the wedge? strongly inclined downwards and in the closed position (Figures 1 and 2), the distance from the opposite wedge surface 29 of the locking stop 6 of the associated hook 5 of the barrel presents a small amount? The lower surface 27 of the wedge therefore rests on the opposite surface (Figure 2) of the hook 5 of the barrel. exhaustion? 31 of the barrel and the surface of the bottom of percussion 11, since? the latch 7 under the action of the spring 16 urges the hook 5 of the barrel and therefore the barrel 1 cooperating with them! there 9 and 25 in the direction of the arrow B (figure 1) towards the bottom 32 of the shutter 3?

The latch 7 in the embodiment shown in the blocking direction is disposed on a shutter slide 34, which? buoyant., to come and go in the direction of the arrow A substantially parallel to the longitudinal direction Le of the shutter 3? In the unlocking direction the bolt 7? arranged on the cursor 36, which? supported on the underside of the shutter 3 and pre? 3go the bracket 33 d. Of the firing device?

The helical pressure spring 16 acts on one side on a rear bearing surface 40 of the central region 38 of the slide 34 as a shutter spring and on the other side slightly above the axial pin 15 on a cross 41 of the trigger 13, essentially extending vertically as a firing spring. The two extremes t? deH-a-mol-la -16 are in-wind-parts-recessed? suitably in the-neavi-, outlined in the central-area_38_and_of-the-crosspiece 41?

As shown in Figure 3, the firing pin 18, which? disposed above the extremity? 37 of the slide 34 and of the trigger 13 has a hanger 42, which during the loading can? be brought to rest on a rear abutment surface 43 of the slider 34 and blocks the slider 34 against an opening of the shutter of the slider 34.

The loading of the firing pin 18, according to Figure 3? happens tii, kndo - a_rit red_this_for__ half_of the dog_19 -, - until_under the action of the spring 16 the end? stop 44 of the crosspiece 41 pitches under the loading stop 24 of the firing pin 18. A variable stop in the for? but of a nut screw 45? self-locking, rotatable and therefore movable in the firing pin 18 below the loading stop 24, it allows to set the length that the end? traverse stop 44

until 41 of the trigger 13 will have to? travel in the course of its movement under the loading stop 24 of the firing pin 18. Ci? takes place for the adjustment of the firing conditions during the shooting, where there is simultaneously by means of the appendix 42? assured that before and during the shot the shutter can not? open since? the slide 34 remains blocked by the abutment surface 43, the appendix 42, the loading stop 24, the stop end 44 and the axial pin 15.?

If instead ? the shot has been made and the firing pin 18 is in the unloaded position according to Figure 1, then the crosspiece 41 of the gripper 13, having the end? stop 44,? substantially stopped between the firing pin 18 and the rear side 46 of the firing base 11 in a forwardly inclined position against an orientably about the axial pin 15; At the same time an appendix 47, provided on the crosspiece 41, from? l? high yes? oriented in a recess 49, provided with a "stop 48, of the cursor 34 resting on this stop 48. in such a way that the cursor 34 also in this position of the firing pin 18? bloc?

against an opening of the gun's bolt.? For this purpose, in addition to figure 1, reference should also be made to figures 6 to 8? Thanks to this execution it is prevented that when possible in the support of the firing pin 18, shown in figure.

ra 1-, on the front side46 of the bottom of the 11 P, therefore in the simultaneously out-of-position position of the firing pin not shown. a loaded cartridge is placed in the firearm and this is then closed, since? in this case with the flip-up barrel lock the cartridge could be triggered and the trigger could be missing so that the trigger swine or firing pin not shown, under the pressure of the trigger the cartridge could not deflect in the direction of the firing pin.

Of particular advantage? the fact that the slide 34 with the trigger inserted 13 and the shutter or the spring 16 after the extraction of the pin as

sial 15 from the sides 20 and 21 of the obturator 3 can be oriented downwards without the need to loosen screws? Attention is drawn to the fact that the device according to the invention as a whole, when the set screw 45 serving other purposes than fixing is not taken into consideration, does not require_a single screw_ to then be perfectly assembled and disassembled. e_si-curam.ente - * _ L and tipper guns according to the invention have already? affirm-in practice <

In the area of the cartridge holder 26 on the lower side of the barrel there is provided an extractor pin, which according to the invention? consisting of two partial elements 50 and 51, arranged substantially coaxially and mutually spaced, and?

It is undoubtedly notable that in the course of an opening of the bolt of the weapon from the closed position, represented in figure 1t in the open position represented in figure 2, the axial pin.61 is oriented on a circular trajectory attom o the pin to cemiera 4? It is also detectable that the axial pin 61 when the bolt of the weapon? closed, according to Figure 1, is it located at a vertical level below an imaginary plane in which there are three central axes of the hinge pin 4 and of the transverse pin 64? For this reason, during the upward orientation or during the overturning of the barrel into the open port of the bolt, according to Figure 2, in which the axial pin 61 is located at a vertical distance and above the mentioned - imaginary plane - does a back and forth movement of the clip 65 take place along the transverse spine 64? . the open position - shown in figure-2_the_pin crossbar 64 is - resting on the bottom. of the mallet 65, so that it does not-? possible further re-entry upwards or overturning from the rods.

During the movement illustrated, of course, an orientation of the actuation element 68 or of the angular lever occurs at a non-temporal level, so that the angular surface 68 of the angular cross-member 62, facing towards the barrel 1,? of the second partial element 50 of the extractor pin comes to rest and expels (Figure 2l, the loaded cartridge 56 shown is in particular extracted from the cartridge holder 26 and is therefore unobstructed by the user in the course of unloading the weapon. In particular, there is no compression of the helical pressure spring 59, since the loaded cartridge practically does not oppose ejection resistance. This is different when the cartridge 56, with the shutter closed, according to Figure 1, has been fired.

If subsequently the barrel 1 by opening the bolt is overturned in the position?

the resultant action of Figure-2, then it can be seen that the first partial element 51 of the extractor pin could not follow the forced movement of the second partial element 50.

As a result of the explosion pressure, the cartridge case wall has suffered. to-an expansion - such that it_? now it is locked to the guide of a pressed coupling in the cartridge holder. ci-a-26? In particular, a compression of the spring occurs forcibly. 50., Until the element. the spacer 60 - in the form of a pin projection - rests on the opposite end of the first partial element 51 of the puller pin - each further movement of the second partial element 50, under the influence of the element of a ? = _ operation 58 leads to a sudden detachment of the only? cartridge -56 -, - locked_in the? cartridge holder? 26, and who is then suddenly expelled? In this regard, reference is made to 1 (attention to the fact that not only the usually slightly conical shape of the cartridge cases favors this operation but also the fact that one can do without a polishing of the cartridge holder 26. It is understood that a certain roughness The relatively modest surface of the cartridge holder 26 promotes static friction between the shell of a fired cartridge and the wall of the cartridge holder 26. This static friction is abruptly removed in the aforementioned manner when the spacer 60 meets the p2. imo partial element 51 of the plug of the extractor?

The return of the two partial elements 5? and 51 occurs during the closure of the shutter of? the weapon through the orientation of the extremity? 31 of

the barrel, towards the inside, where the appendix of the first partial element 61 creeping? along the surface 69 of the percussion base 11 is inserted again? This movement is transmitted by means of the spring 59 to the second partial element 50, the movement of which is released from the rearward orientation of the actuation element 58?

How ? It is easy to imagine that for the rest the closing of the bolt of the weapon will last for you a backward push of the bolt 7 of the slider 14 due to the rounding 70 of the rear hook> 6 of the barrel occurs in antagonism to the spring 16 load, which constitutes at the same time the mol - la_disparo, _so far when the bolt 7 under the of this_spring_16_pu? stop again-? at the stop 6 on the hook 5 of the rod.

The firing blade 14 has a crossbar -41, which extends upwards and at the end of which stop 44 in the loading position rests the loading stop 24 of the firing pin 18? In addition, the axial pin 15? arranged in the area of the corner formed by the blade 14 and the crosspiece 41 and? arranged_.on_piano.of the percussion base 11 of? the shutter 3 pi? - close to the axial pin 22 - to the firing pin 18 - <

In the embodiment shown, the preferred axial pin 15? arranged in the area of the crosspiece 41-contiguous to the blade 14. This arrangement not only involves a_pi ?.

-voie transmission to-Lever for the griletto., _ as mentioned at the beginning-, but.olire a ci? also involves an antageous possibility? The safety stop 23 in the safety position and the loading stop 24 in the firing device loading position are located approximately at the height of the firing device. axial pin 22 of the firing pin 18 between this and the percussion bottom 11 of the shutter 3?

There? guarantees optimal use of the space available in this region?

In the embodiment shown the safety stops 23 on the firing pin 18 and the extreme mit? stops on the crosspiece 41 are correspondingly stepped to each other, so that the end stop 44 engages behind the safety stop 23? Is trigger action 13 not red in this safe position? An? that when the dog is pulled backwards in reasons; of a certain angular amount, when free skiing falls back into the locked position without the firing pin 18 having been able to fall onto the firing pin, not illustrated more? in detail it is disposed in the bottom 11 and has been able to trigger the cartridge 56?

In the loading position, the surface of the loading stop 24, resting on the? the extremity stop 44 of the crosspiece 41,? indi born.in..mo.do.-from .descend resp.ett.0 to the axial.pin> 2.2, so that this surface in the direction of movement of the crossbar, that this pre? feel during the shot-, it deviates_a_ritroso upwards obliquely from the stop-end..44.of it. -the end? stop 44 -It moves on a circular_trajectory around the axial pin 15 and this movement first occurs tangentially, with overcoming of the static friction, the surface 24 deviates thereby. to say backwards towards lustrerait? free of the loading stop, so that-? start the rotation of the firing pin 18_ while the rest 24 still covers the end? 44. In-particular-it is supposed to -have-place even. a certain acceleration of the s movement of the extremity? of stop 44 by the stop-24 or its surface, as soon as? been for once the static friction was overcome? There? involves a particularly direct, rapid and dry release of the firing device unlike a so-called traction firing device, in which, first of all, on a determined movement section of the firing device, can? occur a slide? to, which turns back into static friction to reduce the pressure of the finger on the gril? bed 13, between stop and the end? auction stop, how? expected in the current state of the art?

To get the most? possible a linear between ends? stop 44 and stop of ca-?

ricamento 24 device according to the invention, the edge of the end? stop 44, which is accepted?. at the loading stop 24, can? be performed with sharp edges to assist in the development of the necessary static friction in the loading position. be such that the angle would be exceeded, necessary for the block? If there is no static friction between the direction of orientation of the crosspiece and the inclination of the surface 24?

Preferably the end? stop 44 of the crosspiece 41? arranged staggered towards the hair dryer? do 11 of percussion with respect to the axial pin 15 * in such a way that the line of action of the force e? exerted by the loading spring 17 through the loading stop 24 on the crosspiece 411 extends to a lever distance from the axial pin 15? This execution puts the firing device in the release direction under a certain preload in contrast to the firing spring 16 load, which? suitably carried out in the form of a helical pressure spring and at the same time represents a shutter spring, since it is spring-loaded. the slider 34 in the sense of locks. In the loading position, the o-34 slider is blocked by a stop on the firing pin 18. In the safety position it is represented in figure _ 2 instead of sliders or 34 - in antagonism to the -load of the spring 16 can? be moved-in the direction towards the stock not_shown_ (in the figures_ towards the right) _, _ as_si_cx? that the latch 7 can? disengage from the stop to the back to allow the barrel to be overturned and therefore to load or unload the folding barrel gun?

As can be easily seen from the figures in the example of embodiment shown the gripping 13 of the firing device? of displacement substantially below the percussion floor 11, which contributes to a compact construction of the device if the i nvenzi on is included.
