Definitions
- the invention relates to a multi-load handgun according to the preamble of claims 1 and 4.
- Breech locks are used for repeating and self-loading self-loading weapons (self-loading weapons that are ready to fire with the breech closed) of various types.
- the invention particularly extends to self-loading pistols mi: Emsteck magazine.
- the primary purpose of the breech-lock of a bullet-type handgun is to keep the breech open after the last shot to indicate to the shooter that there is no longer a shot and to shorten the subsequent loading process.
- the mechanism that forms the breech block is located entirely inside the weapon, for example with the Walther PP and PPK pistols. In this case, the shooter must insert a loaded magazine or the like. take the slide or slide, pull it back slightly and then release it. This is faster than normal loading, which means that the closure is fully retracted over its entire 3198
- the breech held by the breech lock is to be left forward when the weapon is unloaded, first remove the magazine and then carry out the same operations as described above. If the closure is in its front position, the magazine can be reinserted.
- Another, widespread mechanism of the breech lock therefore has a lever which is located on the outside of the weapon and can be pivoted about a transverse axis and which engages with its end on the one hand m the path of movement of the magazine feeder and on the other hand m the path of movement of the breech where it m a recess of the Closure can occur when it is open and the magazine is empty.
- a handle sits on the pivoting lever. If such a weapon is a full magazine m inserted a weapon in which the breech is held close to the rearmost position by the breech lock, then it is sufficient to pivot the said pivot lever by pressing on its handle so that it releases the breech and this drives forward.
- the loading process therefore does not require the use of the shooter's second hand to make the weapon ready to fire again.
- the sports shooter who only uses his weapon at the shooting range, has enough time to reload.
- the breech lock of self-loading sport pistols therefore usually allows the breech to slide forward again for safety reasons when the empty magazine is removed.
- the aim of the invention is to provide a further handgun which has a lock which can be released by means of a handle.
- a second handle is coupled to the first handle and is arranged opposite it on the other longitudinal side of the weapon.
- the locking device can also be operated by a left-hander in the same way by means of a handle as was previously only possible for a right-hander.
- This improvement is simple, i.e. without major changes to existing weapons, and inexpensive to carry out.
- the improvement can either be used or omitted.
- the breech block can have a slide which engages the magazine feeder from behind and carries on the side the first handle which extends outwards through a first slot in the weapon housing or grip. In this case, it is easy to mount the second handle on the other side of the slide, which extends outwards through a second slot which is formed opposite the first in the housing or handle.
- the first handle sits on a first pivot lever which is pivotable about a transverse axis running transversely to the longitudinal axis of the weapon, and that a second pivot lever with the second handle sits on the other side of the weapon , which can be pivoted about the same transverse axis, and that both pivot levers are connected to one another in a rotationally fixed manner by means of a pivot shaft which extends coaxially to the pivot axis.
- Swivel levers can be arranged within the walls of the housing or handle, but are preferably outside of them, since the entire wall thickness of the housing or handle can then be used to support the swivel shaft. Also then no grooves that have to extend along the movement path of the handles penetrate the wall of the housing or G ⁇ ff consortiums and thereby weaken this.
- the above-mentioned Colt-Brownmg construction has a swivel lever designed, stored and arranged in this way, the swivel shaft of which can sometimes even serve as an anchorage for a locking member and must be removed to disassemble the weapon before the breech can be removed.
- the closing spring is usually used as a detent spring, but other solutions are also known, for example fastening using a steel clip, which resembles a bicycle chain lock (Tokarew TT 1930 and 1933).
- the pivot lever or its pivot shaft is not used to disassemble the weapon.
- the first pivot lever is firmly connected to the pivot shaft, for example riveted to it.
- the pivot lever has an upwardly extending projection which, after the weapon has been assembled, is encompassed by another component with play so that the pivoting movement of the pivot lever is not impeded, but the pivot shaft no longer comes out of its receiving bore in the housing or handle can be pulled out (claim 3).
- This component is preferably a downwardly extending long edge on the closure. If the lock is removed, the swivel lever with the swivel shaft can simply be pulled out.
- This holding projection can be arranged at any point on the pivoting lever, but is preferably arranged near the junction of the pivoting shaft, since the pivoting movements of the pivoting lever take up the shortest distances there.
- the second swivel lever can in principle be permanently attached to the free end of the swivel shaft, since, as mentioned above, the dismantling of the swivel lever need not be necessary to disassemble the weapon.
- the second pivot lever is preferably detachably attached to the pivot shaft. It is possible to form the free end of the swivel shaft out of round, for example as a square, to insert a complementary hole in the second swivel lever and to hold it from the outside by means of a screw which is screwed into the swivel shaft. The second swivel lever is also held in place. When dismantling or shooting there is a risk that the small screw is lost or the thread of the swivel shaft is damaged.
- the holding of the second pivot lever is therefore achieved according to a preferred embodiment of the invention in that this second pivot lever is attached by means of a ba onett lock on the housing or on the handle of the weapon.
- a bayonet lock initially allows the second pivoting lever to move in a straight line along the transverse axis, which is also the central axis of the
- the cross shaft penetrates at least part of the second pivot lever with a non-circular section.
- the receiving bore in the second pivot lever is at least so far complementary to the non-circular section that the second pivot lever pivots with virtually no play when the cross shaft is pivoted.
- the second swivel lever is therefore not attached to the end of the transverse axis, but is only connected to it in a rotational test.
- the bayonet lock which allows the pivoting lever to be rotated to a limited extent, does not axially fasten the pivoting lever, but does not detach it from the wall of the housing or handle.
- first or the second pivot lever is located on which side of the weapon the first or the second pivot lever is located.
- first swivel lever is on the left side of the weapon above the Handle seated swivel lever meant.
- second swivel lever or both swivel levers can be designed with a touch finger which interacts with the feeder of the magazine. In the latter case, the connection of the two pivot levers need not be rotationally fixed.
- the non-circular section of the cross shaft can e.g. be a square.
- the end of the cross shaft is preferably provided with longitudinal grooves which are distributed uniformly over the circumference and extend to the end of the cross shaft. Together with the complementary hole in the swivel lever, a so-called multi-groove profile connection is thus created, which is suitable for transmitting a high torque.
- the breech lock according to the invention can be used in all-load handguns of all kinds, preferably in self-loading weapons and particularly preferably in self-loading pistols, in which an external pivoting lever is assigned to the conventional pivoting lever lying on the outside on one side of the handle on the opposite side.
- the invention interferes with the interior of the mechanism of the self-loading pistol in no way.
- the second swivel lever does not require any space in the interior of the handle of the pistol.
- the invention also relates, as noted at the beginning, to a weapon according to the preamble of claim 4.
- a weapon is known from the magazine "Deutsches Pontournal", January 20C1, pages 8-16.
- Colts In the well-known self-loading pistols according to the Colt
- the Brown g-System When disassembling the weapon, the Brown g-System, such as the high-performance brownmg system, must first remove the all-round left-hand pivot lever (the first pivot lever) before the bolt or slide can be removed with the barrel forward.
- the lock or slide is first placed in a special position. Then the first pivot lever is pivoted a recess to the left of the underside of the closure or slide. Now the first swivel lever can be pulled out of the handle to the left.
- the disassembly can take place in the same way. Pulling the shaft out of the second pivot lever does not require an additional handle, but takes place when the shaft is pulled out of the handle anyway.
- the second swivel lever can remain on the handle. However, since it is not reliably attached to it, it can fall out of the handle unnoticed when handling the handle. Because the weapon can also be assembled without a second swivel lever, this falling out can even go unnoticed.
- the multi-load handgun mentioned at the outset has a lock which essentially limits the pivoting path of the second pivoting lever to a region which is outside the pivoting position which is necessary for installing and removing the second pivoting lever.
- This lock allows the free pivoting movement of the second pivoting lever only its operating range of motion; additionally at most up to the swivel position, which has not yet reached the angular position of the second swivel lever required for installation and removal.
- the lock can lie precisely on the boundary of the operating range and thus limit it. It is therefore not necessary to limit it by means of the closure or slide, for example.
- the lock can be formed by a pin, for example, which is screwed in or screwed in from the outside of the housing or handle and is prevented from falling out by the closure or slide. This pin or screw then engages the bayonet lock approximately m and limits its pivoting range.
- a disadvantage is the fact that the pin or the lock must be strong enough to withstand the stresses in operation to which he or she is exposed when the operating range of movement is limited. Therefore, according to one embodiment of the invention, it is proposed that the lock be installed in such a way that it does not become effective within the operating range of motion, but only outside of it, and therefore is not exposed to any loads during normal operation. Of course, however, the lock must still be attached so that the second pivot lever when the lock is effective cannot reach the angular position that allows its expansion.
- the lock can be designed as a male spigot which e.g. m the bayonet lock of the second
- the lock is designed as a pin which is arranged on the outside of the handle opposite the second pivoting lever.
- the free end of the second pivot lever abuts the breech or slide when the pivot lever is pivoted with the weapon assembled.
- the second pivot lever preferably does not abut the pin. This is namely at a point a little above the second pivot lever and just below the lower edge of the breech or slide and can therefore not be reached by the second pivot lever when the weapon is assembled.
- the pin can be soldered or glued to the handle after the second pivot lever has been installed.
- this pin has the disadvantage that this pin has to be removed for disassembly.
- the invention does not now provide a pin which is more easily detachably fastened; but, conversely, a pin designed as a fixed projection, which can only be removed by destruction.
- This projection is chamfered on the top, so that the pivot lever can be attached with a slight play and / or resiliently deformed by the bayonet lock when it is first assembled.
- the shaft of the first pivot lever then centers the second pivot lever and prevents any deformation. It is also de
- Edge of the projection facing its operating position is preferably formed perpendicular to its pivoting path, so that when the weapon is disassembled it cannot or cannot easily get over the projection.
- the projection is formed on a largely made of plastic handle or housing that is not quite as rigid as a metal housing. Furthermore, the projection is preferably on the upper edge of the housing or
- Handle pieces arranged where this can more easily escape to the inside of the housing h.
- the projection is preferably arranged at a point at which the housing or handle allows slight deformation transversely to the weft direction and m horizontal direction.
- the Bet ⁇ ebs movement path of the second swivel mist is limited downwards by a stop, that is to say on the preferably lower side of the Bet ⁇ ebs movement path and opposite the projection mentioned.
- the first pivot lever is removed and the second pivot lever remains.
- the second pivot lever can be pressed against the stop and thus take up a position in which the shaft of the first pivot lever can be inserted quickly, easily and precisely into the second pivot lever. So the assembly is much easier.

- Fig. 1 shows a horizontal cross section through part of a handle 1 of a self-loading pistol, the shot direction pointing to the left.
- FIGS. 1 and 5 have approximately the same scale, while the overall representations of the handle 1 of FIGS. 2, 3 and 4 have a scale that is smaller than this. 2 and 4 points to the bottom left, m Fig. 3 to the bottom right and m Fig. 5 to the top right.
- the handle 1 surrounds a magazine shaft 3.
- a horizontal transverse bore 13 which rotatably seats a pivot shaft 7, with the left end of which is riveted to a first pivot lever 5.
- This pivot lever 5 extends approximately horizontally and in the longitudinal direction of the handle 1, on the left side of which it rests on the outside.
- the front end of the pivot lever 5 is, as already mentioned, with the
- the pivot lever 5 has, after approximately two thirds of its length, a touch finger 9 facing the handle 1, which extends through an opening in the handle 1 and protrudes a little m into the magazine shaft 3.
- the finger 9 allows the cartridges to slide past it until after the last cartridge has been removed from the magazine by its feeder is recorded and charged upwards.
- the magazine with its feeder is omitted from the drawing for simplicity.
- the breech or slide runs to the rear.
- catch piece 11 On the top of the leg lever 5 e catch piece 11 is formed near its rear end, which extends upwards and abuts against it from below when the closure is closed.
- the breech has a recess on its underside, which the catch piece can fold in when the breech is in its rear position, and when the finger 9 is raised by the feeder of the magazine.
- the pivot lever 5 can be pivoted upward with its rear end about the central axis of the pivot shaft 7 because the touch finger 9 and thus also the catch piece 11 from the feeder of the Magazine to be raised. If the closure now wants to return to the front in its closed position, then it runs onto the finger 9 and remains after leaving its rearmost position.
- the pivot lever 5 is arranged on this em upwardly projecting holding piece 15. If the closure is pushed onto the handle 1 from the front, the holding piece 15 is gripped by the closure in such a way that its outer edge is on the outside of the holding piece 15 and below its upper edge. Now the holding piece 15 no longer move outwards. If, however, the closure is removed from the handle 1, the pivot shaft 7 can be pulled out of the bore 13 by means of the pivot lever 5. A rest, which acts on the pivot shaft 7, is not necessary and is also not provided.
- the arrangement shown corresponds essentially to a known lock, and the first pivot lever 5 can be used in general and without any further addition.
- the free end of the pivot shaft 7 has a multi-groove profile 29, the mutually parallel grooves of the same angular distance extending up to this free end h.
- a spigot 23 with a bore with a complementary profile 31 is pushed onto this multi-groove profile 29.
- This nozzle 23 forms part of a second pivot lever 17 which extends from this nozzle 23 to the rear, where a second handle 21 is formed.
- the first and second pivot levers 5, 17 are almost identical on the outside, they extend parallel to one another and they carry their respective handles 19, 21 at opposite points.
- the second handle 21 of the second pivot lever 17 is located for the actuating thumb of the left hand of a lens protector at the same point as is the case with the handle 19 of the first pivot lever 5 for the right thumb of a right protector.
- a projection 25 is formed, which corresponds to the recess 33 of the part of the receiving bore 13 which receives the nozzle 23.
- the projection 25 and the recess 33 are arranged such that they face each other when the second pivot lever 17 is in an angular position which it cannot assume in normal operation.
- This installation angular position is shown in FIG. 3.
- the second pivot lever 17 is pivoted so that the projection 25 m enters a recess m in the wall of the handle 1, which thereby has a counter projection 27 (FIG 1) forms, which is engaged by the projection 25. This prevents the second pivot lever 17 from becoming loose.
- the second pivot lever 17 is thus attached to the right side wall of the handle 1 by means of a bayonet catch.
- the two swivel levers 5, 17 are installed as follows:
- the second pivot lever 17 is inserted by means of the described bayonet lock m in a certain rotational position m, the handle 1, as shown in FIG. 3.
- the second pivot lever 17 can only assume this rotational position if the closure is removed.
- the second pivot lever 17 is then pivoted m its position of use. Now the first pivot lever 5 with the pivot shaft 7 m is inserted into the receiving bore 13 (shown in FIG. 4). The touch finger 9 m penetrates the opening m assigned to it in the left wall of the handle 1. At the same time, the multi-groove profile 29 penetrates the complementary profile 31 (see FIG. 3).
- the disassembly is done in reverse order.
- the locking device shown only requires a single, additional part to the already known first pivoting lever 5, namely the second pivoting lever 17.
- This second pivoting lever 17 is an investment casting which is relatively inexpensive to produce and whose connecting piece 23 has the complementary profile 31 , which is already roughly cast, can only be cleared with a cutting tool.
- FIG. 6 shows a section of a self-loading pistol with: a handle 1 made of reinforced plastic, a slide 43 which can be moved and removed on the handle and is removable, a second swivel lever 17 and a trigger (no reference number).
- the slide 43 runs approximately horizontally, the handle (only the upper part of which is indicated) extends obliquely downwards and the direction of the shot is to the right.
- the second swivel lever 17 extends parallel to the carriage 43 in the rest position shown, is fastened with its front end to a shaft which rigidly connects it to the breech catch lever, which is not visible and is located on the right side of the weapon, and points at its rear End up a handle.
- the second pivot lever 17 is omitted, so that a receiving bore 13 and an adjoining recess 33 are visible, which together form part of the ba onet holder for the second pivot lever 17.
- protrusion 41 Behind and above the recess 33 on the outside of the handle 1 1 protrusion 41 is formed. This sits on a free upper edge of the handle 1 and thus adjoins the lower edge of the slide 43 when the pistol is assembled. As shown in FIG. 8, the wall thickness of the handle 1 is particularly small at this point.
- the projection 41 is designed as a flat, lying cuboid, the upper side of which is chamfered (chamfer 45). This bevel 45 starts from the upper edge of the handle 1.
- the projection forms an essentially horizontal transverse edge 47 which faces the second swivel arm 17.
- the second pivot lever 17 Before the carriage 43 is placed on the handle 1, the second pivot lever 17 can be mounted.
- the second pivot lever 17 can pivot within its operating range. This is delimited by the carriage 43, against which the rear end carrying the handle strikes from below. However, the second pivot lever 17 does not abut the projection 41. The projection 41 thus does not interfere with the operation of the second pivot lever 17 and is not damaged by the impact of the pivot lever 17.
- the second pivot lever 17 In the usual disassembly of the weapon for the purpose of remigment and maintenance, the second pivot lever 17 always remains in place because it is prevented by the projection 41 from detaching from the handle 1. But if it is to be removed, then it is sufficient to press the projection 41 forcefully inwards and then to pivot the pivot lever 17 over this position m, which releases the ba onett lock.
- a shoulder 49 is preferably formed below the second pivot lever 17. This limits the pivoting movement of the second pivot lever 17 downwards in such a way that it rests almost on the shoulder 49 in its rest position. Like the projection 41, the shoulder 49 does not hinder the pivoting movement of the second pivot lever 17 during normal use of the weapon, but does form a stop for the second pivot lever 17 when it is not connected to the first pivot lever. After the usual disassembly of the weapon, the second pivot lever 17 remains on the weapon. However, the first swivel lever had to be removed, otherwise disassembly would not have been possible.
- the first pivot lever is pushed in laterally from the left with its shaft m.
- the shaft should now be inserted with the non-circular cross section of its free end, the receptacle in the second pivot lever 17. So that this can be done easily and quickly, the pivot lever 17 is caused to sit on the shoulder 49. Now the first and the second pivot lever 17 both take a corresponding position em. In this the
- Shaft of the first pivot lever can be inserted quickly, effortlessly and correctly into the second pivot lever 17.
- the invention can be implemented not only on a weapon of the type shown, but also on weapons with a different construction principle, such as long weapons or the like.
- the self-loading pistol shown shows a particularly advantageous embodiment of the invention.
