Definitions
- the invention relates to a pistol having a housing, a longitudinally slidably guided thereon carriage, guided in the carriage run and a locking device which is formed by a head of the barrel, a locking block and a pair of guided in a transverse groove of the head locking bodies, which engage by the action of the locking block in recesses on the inside of the carriage and so lock the barrel with the carriage.
- a generic pistol is from the GB 668117 known.
- the locking body are circular cylindrical rollers which bear against flat boundary surfaces of the transverse groove and thus transmit the reaction force of the barrel when shooting on the carriage.
- a line contact Between the flat boundary surfaces and the circular cylindrical rollers is a line contact, which generates a high surface pressure in both parts (so-called "Hertz'sehe pressure").
- Line contact also exists between the rollers and the gate of the interlocking block. It has been shown that this high local surface pressure on all three parts, but especially on the walls of the transverse groove, resulting in deformation that can lead to breakage.
- the rollers are fitted, so that the contact line is shorter than the height of the rollers. This type of locking is thus used only for very small caliber and weak propellant charges.
- Out AT 403847 B is a semi-rigid locking system for a firearm with firmly connected to the housing barrel known, the closure by means of in radial Direction guided locking body is lockable in the housing. In order to reduce the shearing force acting on the locking bodies, the recoil is gradually reduced. In this case, there is a clearance between the locking body and the housing, whereby the closure first acts as a grounding.
- the peak values of the local surface pressure are to be reduced, so that the pistol is also suitable for normal to larger caliber and even for highly explosive ammunition.
- the locking block has two symmetrical about the longitudinal median plane first planar wedge surfaces, that the locking bodies are cylinders, whose lateral surface two parallel, in the transverse groove adjacent planar guide surfaces, a respective other locking body facing first flat wedge surface and one of each facing away from other locking body, has to engage in the respective recess of the carriage certain engagement surface, and that the head of the barrel is guided on both sides by means of first grooves and first strips in the carriage and by means of second grooves and second strips in the locking block.
- the guide surfaces of the locking body lie on a large area on the walls of the transverse groove, which significantly reduces the surface pressure and avoids local peaks.
- this advantageous type of locking can also be used for normal to large caliber and high-explosive ammunition, namely at extended life.
- the guidance of the head in the carriage ensures a clean assignment of the components involved in the locking in the vertical direction.
- the engagement surface of the locking body and the recess in the carriage can be purely circular cylindrical. In an advantageous development, they consist of a circular cylindrical zone and of a tangentially adjoining the front inclined, in particular flat, zone. This reduces the friction when unlocking and makes it easier.
- an angle to the longitudinal direction is advantageous, preferably also 45 degrees.
- the locking block is fixed at its side facing away from the head bottom by means of a second transverse groove relative to the housing in the longitudinal direction. This allows the lock block to slightly adjust in the transverse direction. This ensures a uniform distribution of the forces acting on the two locking bodies.
- the locking block forms on the side facing away from the head bottom of the second wedge surfaces a horizontal plate which overlaps the locking body partially.
- the plate holds the locking body in the transverse groove, which is also advantageous when assembling the gun.
- the plate can thus act in a similar manner as a waist of the pinch rollers in the prior art, if such effect is desired. As a result, then the entire height of the locking body for the guide surfaces is available.
- Fig. 1 the housing 1 of a pistol is indicated by dashed lines. In full line is a section through the invention relevant parts of this gun to see in the longitudinal center plane.
- a carriage 2 On the housing 1, a carriage 2 is guided in guides 34 displaceable in the longitudinal direction.
- a barrel 3 is guided displaceably in the longitudinal direction.
- a closing spring rod containing a closing spring 8 engages.
- Behind the cartridge or cartridge chamber 12 of the barrel 3, a shock pad 5 is formed in the carriage 2, followed by a percussion device 4. This is not shown in detail, since it is known per se and is immaterial to the invention.
- a guide block 6 is fixed by means of pins 14 or the like.
- the guide block 6 forms a stop 13 for the returning barrel 3.
- the locking device is denoted by 10 summarily.
- the housing-fixed part of the locking device 10 is a locking block 20 which is held by a bolt 11 with respect to the housing 1 in the longitudinal direction.
- the end face 15 of the locking block 20 forms an abutment for the closing spring 8, the back surface 16 of the locking block 20 is supported on the guide block 6 from.
- the bolt 11 is designed here pivotable about one of the pins 14 as a Zerleghebel.
- FIGS. 2 and 3 show the locking device 10 from obliquely below or in section seen, omitting the components not directly involved in the lock.
- the locking block 20 has for fixing in the longitudinal direction with respect to the housing 1 on its underside (in the picture above) a retaining groove 17, in which the bolt 11 (s. Fig. 1 ) engages, and symmetrically to the longitudinal center plane two wedge surfaces 21.
- the rear part of the barrel 3 forms a running head 22 with a transverse groove 23 on its underside, s. also Fig. 4 , In the transverse groove 23 a locking body 24,25 is guided on both sides in the transverse direction.
- first grooves 28 and first strips 29 in the carriage 2 are guided by means of first grooves 28 and first strips 29 in the carriage 2 and by means of second grooves 30 and second strips 31 on the locking block 20 in the longitudinal direction.
- groove 28; 30 and bar 29; 31 may be arranged in one or the other of the components.
- Fig. 4 are the components of the Fig. 2 , namely, the housing-fixed locking block 20, the head 22 of the movable barrel 3, the locking body 24, 25 displaceable in the transverse groove 23 and the carriage 2 with the indentations 28, enlarged in plan view.
- the locking block 20 has symmetrical with respect to the longitudinal center plane, converging from its side walls 18 to the rear first wedge surfaces 21, which include an angle 39 of 40 to 50 degrees, preferably 45 degrees with the longitudinal direction. To the wedge surfaces 21 close to the rear end of the locking block 20 parallel locking surfaces 32 at.
- the head 22 of the barrel 3 has on its underside (in the picture above) a transverse groove 23 which forms straight flat vertical surfaces for guiding the locking bodies 24, 25. Significant forces are registered by the locking bodies 24, 25 over these surfaces, the surface pressure not assuming excessive peak values thanks to the surface contact.
- the transverse groove 23 is interrupted by a central elongated channel 26 in which the locking block 20 is guided.
- the channel 26 is at its rear end (in Fig. 4 right) bounded by a transverse surface 33. This serves as a stop for the back surface 16 of the locking block 20 in the locked position.
- the locking bodies 24, 25 are cylinders whose lateral surface is not circular, but is composed of a first guide surface 35, a second guide surface 36 parallel thereto, a second wedge surface 38 and an engagement surface 40.
- the angle 39 between the second wedge surface 38 and the longitudinal direction is 40 to 50 degrees, preferably 45 degrees.
- the engagement surface 40 in turn may be formed differently, here it consists of a circular cylindrical zone 41 and an inclined, for example, flat transition zone 42.
- the oblique transition zone 42 is here a plane which with the longitudinal direction an angle 43 of 40 to 50 degrees, preferably 45 Degree, includes.

- they consist of a circular cylindrical zone 44 and an inclined, for example flat transition zone 45.
- the transition zone may be flat, but need not. At a corresponding angle 43, it reduces the force and friction required for unlocking.
- the Fig. 5 to 7 show three different operating positions of the lock 10, based on which the operation is explained.
- Fig. 5 shows the locking device locked and ready to fire.
- the carriage 2 and the barrel 3 take their foremost position. In this position, the head 22 of the barrel 3 is located on the impact plate 5 and the back surface 16 of the locking block 20 is located on the head 22 of the barrel 3 (s. Fig. 1 ).
- the locking body 24, 25 are engaged in the recesses 27 in the carriage 2 and are held by the side walls 18 of the locking block 20 in this position.

Description
Die Erfindung betrifft eine Pistole mit einem Gehäuse, einem darauf in Längsrichtung verschiebbar geführten Laufschlitten, einem im Laufschlitten geführten Lauf und einer Verriegelungsvorrichtung, welche gebildet ist von einem Kopf des Laufes, einem Verriegelungsblock und einem Paar von in einer Quernut des Kopfes geführten Verriegelungskörpern, welche durch Einwirkung des Verriegelungsblocks in Ausnehmungen an der Innenseite des Laufschlittens eingreifen und so den Lauf mit dem Laufschlitten verriegeln.The invention relates to a pistol having a housing, a longitudinally slidably guided thereon carriage, guided in the carriage run and a locking device which is formed by a head of the barrel, a locking block and a pair of guided in a transverse groove of the head locking bodies, which engage by the action of the locking block in recesses on the inside of the carriage and so lock the barrel with the carriage.
Bei den meisten Pistolen erfolgt die Verriegelung durch Kippen oder Verdrehen des Laufes bezüglich des Laufschlittens. Die dadurch entstehenden Massenkräfte beeinträchtigen die Handhabung und damit die Treffsicherheit. Dieser Nachteil tritt bei Verriegelung mittels Verriegelungskörpern, welche in aller Regel kreiszylindrische Rollen sind, nicht auf. Trotzdem hat diese Art der Verriegelung keine Verbreitung gefunden.Most pistols lock by tilting or twisting the barrel relative to the carriage. The resulting mass forces affect the handling and thus the accuracy. This disadvantage does not occur when locking by means of locking bodies, which are usually circular cylindrical rollers. Nevertheless, this type of locking has found no distribution.
Eine gattungsgemäße Pistole ist aus der
Es wurde zwar versucht, die betroffenen Teile so zu härten, dass sie hohen Flächenpressungen standhalten. Dabei hat sich örtliches induktives Härten nicht bewährt, weil es erstens zu aufwendig und nicht prozesssicher ist, und weil zweitens am Übergang von der gehärteten auf die ungehärtete Zone Risse auftreten. Diese Nachteile treten beim Gasnitrieren nicht auf, wegen der begrenzten Härtetiefe von maximal 0,35 mm sind aber bei Linienberührung Verformungen in der darunter liegenden ungehärteten Zone nicht zu vermeiden.An attempt was made to harden the affected parts in such a way that they withstand high surface pressures. In this case, local inductive hardening has not proven successful because, firstly, it is too costly and not process-reliable, and second, because cracks occur at the transition from the hardened to the uncured zone. These disadvantages do not occur in gas nitriding, but due to the limited depth of hardness of a maximum of 0.35 mm deformations in the underlying uncured zone can not be avoided on line contact.
Aus
Es ist Aufgabe der Erfindung, in einer Pistole wie eingangs angegeben die Verriegelung so zu gestalten, dass die genannten Nachteile nicht auftreten. Die Spitzenwerte der örtlichen Flächenpressung sollen verringert werden, sodass die Pistole auch für normale bis größere Kaliber und sogar für hochbrisante Munition geeignet ist.It is an object of the invention to design in a pistol as mentioned above, the lock so that the disadvantages mentioned do not occur. The peak values of the local surface pressure are to be reduced, so that the pistol is also suitable for normal to larger caliber and even for highly explosive ammunition.
Erfindungsgemäß wird das dadurch erreicht, dass der Verriegelungsblock zwei um die Längsmittenebene symmetrische erste ebene Keilflächen aufweist, dass die Verriegelungskörper Zylinder sind, deren Mantelfläche zwei parallele, in der Quernut anliegende ebene Führungsflächen, eine dem jeweils anderen Verriegelungskörper zugewandte erste ebene Keilfläche und eine vom jeweils anderen Verriegelungskörper abgewandte, zum Eingriff in die jeweilige Ausnehmung des Laufschlittens bestimmte Eingriffsfläche aufweist, und dass der Kopf des Laufes beiderseits mittels erster Nuten und erster Leisten im Laufschlitten und mittels zweiter Nuten und zweiter Leisten im Verriegelungsblock geführt ist.According to the invention this is achieved in that the locking block has two symmetrical about the longitudinal median plane first planar wedge surfaces, that the locking bodies are cylinders, whose lateral surface two parallel, in the transverse groove adjacent planar guide surfaces, a respective other locking body facing first flat wedge surface and one of each facing away from other locking body, has to engage in the respective recess of the carriage certain engagement surface, and that the head of the barrel is guided on both sides by means of first grooves and first strips in the carriage and by means of second grooves and second strips in the locking block.
Die Führungsflächen der Verriegelungskörper liegen großflächig an den Wänden der Quernut an, was die Flächenpressung signifikant verringert und örtliche Spitzenwerte vermeidet. Dadurch, dass die Verriegelungskörper in Richtung der Quernut länglich sind, ist ihre Anlagefläche auch in dieser Richtung erheblich. Mit demselben pressungsvermindernden Effekt wirken zwischen den Verriegelungskörpern und dem Verriegelungsblock ebene Keilflächen. Insgesamt sind so alle Linienberührungen durch Flächenberührung ersetzt. So kann diese vorteilhafte Art der Verriegelung auch für normale bis große Kaliber und hochbrisante Munition eingesetzt werden, und zwar bei verlängerter Lebensdauer. Die Führung des Kopfes im Laufschlitten sichert eine saubere Zuordnung der an der Verriegelung beteiligten Bauteile in Höhenrichtung.The guide surfaces of the locking body lie on a large area on the walls of the transverse groove, which significantly reduces the surface pressure and avoids local peaks. The fact that the locking body are elongated in the direction of the transverse groove, their contact surface is considerable in this direction. With the same pressure reducing effect, flat wedge surfaces act between the locking bodies and the locking block. Overall, all line contacts are replaced by surface contact. Thus, this advantageous type of locking can also be used for normal to large caliber and high-explosive ammunition, namely at extended life. The guidance of the head in the carriage ensures a clean assignment of the components involved in the locking in the vertical direction.
Günstige Kraft- und Reibungsverhältnisse herrschen, wenn die erste und die zweite ebene Keilfläche des Verriegelungskörpers mit der Längsmittenebene einen Winkel von ungefähr 45 Grad einschließt. In der praktischen Erprobung hat sich gezeigt, dass die genannten Keilflächen reibschlüssig sind, wodurch der Vorgang zur Entriegelung von Lauf und Laufschlitten, wo die meisten Kräfte auftreten, schonender für die betreffenden Teile abläuft. Auch wird die Rücklaufgeschwindigkeit des Laufschlittens, und dessen Anschlagenergie im Griffstück verringert. Das hat zur Folge, dass der Rückstoß der Waffe angenehmer ist, und dass die abgefeuerte Patronenhülse nicht so weit aus der Pistole geschleudert wird.Favorable force and friction conditions prevail when the first and second planar wedge surfaces of the locking body subtend an angle of approximately 45 degrees with the longitudinal median plane. In practical testing, it has been shown that the said wedge surfaces are frictionally engaged, whereby the process for unlocking the barrel and carriage, where most of the forces occur, runs more gently for the parts in question. Also, the return speed of the carriage, and its impact energy in the handle is reduced. This has the consequence that the recoil of the weapon is more pleasant, and that the fired cartridge case is not thrown so far out of the pistol.
Die Eingriffsfläche des Verriegelungskörpers und die Ausnehmung im Laufschlitten können rein kreiszylindrisch sein. In einer vorteilhaften Weiterbildung bestehen sie aus einer kreiszylindrischen Zone und aus einer an der Vorderseite tangential anschließenden geneigten, insbesondere ebenen, Zone. Das vermindert die Reibung beim Entriegeln und erleichtert es so. Für die geneigte Zone der Eingriffsfläche ist ein Winkel zur Längsrichtung vorteilhaft, vorzugsweise ebenfalls 45 Grad.The engagement surface of the locking body and the recess in the carriage can be purely circular cylindrical. In an advantageous development, they consist of a circular cylindrical zone and of a tangentially adjoining the front inclined, in particular flat, zone. This reduces the friction when unlocking and makes it easier. For the inclined zone of the engagement surface, an angle to the longitudinal direction is advantageous, preferably also 45 degrees.
In einer vorteilhaften Ausgestaltung ist der Verriegelungsblock an seiner vom Kopf abgewandten Unterseite mittels einer zweiten Quernut gegenüber dem Gehäuse in Längsrichtung festgelegt. Das erlaubt es dem Verriegelungsblock, sich in Querrichtung geringfügig einzustellen. Dadurch ist eine gleichmäßige Verteilung der auf die beiden Verriegelungskörper wirkenden Kräfte sichergestellt.In an advantageous embodiment, the locking block is fixed at its side facing away from the head bottom by means of a second transverse groove relative to the housing in the longitudinal direction. This allows the lock block to slightly adjust in the transverse direction. This ensures a uniform distribution of the forces acting on the two locking bodies.
In einer vorteilhaften Ausführungsform bildet der Verriegelungsblock auf der vom Kopf abgewandten Unterseite der zweiten Keilflächen eine horizontale Platte, die die Verriegelungskörper teilweise überlappt. Die Platte hält die Verriegelungskörper in der Quernut fest, was auch beim Zusammenbau der Pistole vorteilhaft ist. Die Platte kann somit in ähnlicher Weise wie eine Taillierung der Klemmrollen im Stand der Technik wirken, sofern eine solche Wirkung erwünscht ist. Dadurch steht dann die gesamte Höhe des Verriegelungskörpers für die Führungsflächen zur Verfügung.In an advantageous embodiment, the locking block forms on the side facing away from the head bottom of the second wedge surfaces a horizontal plate which overlaps the locking body partially. The plate holds the locking body in the transverse groove, which is also advantageous when assembling the gun. The plate can thus act in a similar manner as a waist of the pinch rollers in the prior art, if such effect is desired. As a result, then the entire height of the locking body for the guide surfaces is available.
