    Pistol with locking by locking body
    The invention relates to pistols having a housing, a longitudinally slidably guided thereon, a slidably guided in Laufschlitten run and a locking device, which is formed by the head of the barrel, a locking block and a pair guided in a transverse groove of the head locking body, which by action engage the locking block in recesses on the inside of the carriage and thus lock the barrel with the carriage.
    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 Verriegelungskörpem, which are usually circular cylindrical rollers on. Nevertheless, this type of locking has found no distribution.
    A generic pistol is known from GB 668,117. Again, the locking body are circular cylindrical rollers which bear against flat boundary surfaces of the Quemut and so the reaction force; of the barrel when shooting transferred to the carriage. Between the flat boundary surfaces and the circular cylindrical rollers, there is line contact, which produces a high surface pressure in both parts (called Hertz's 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, results in deformations that can lead to breakage. To make matters worse in the gun according to GB 668,117 added that the rollers are fitted, so that the contact line is shorter than the height of the rollers. This type of locking is therefore not suitable for large-caliber cartridges or cartridges with high gas pressures.
    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 been proven because it is too expensive and not process-safe, and cracking can occur at the transition from the hardened to the uncured zone. These disadvantages do not occur with gas nitriding, but due to the limited hardening depth of about 0.35 mm, deformations in the underlying uncured zone can not be avoided when touching the line.
    It is therefore an object of the invention to design the lock in a generic pistol 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.
    According to the invention this is achieved in that the locking body are cylinders whose lateral surface has two parallel planar guide surfaces abutting the quemut, a first wedge surface facing the respective other locking body and an engagement surface facing away from the respective other locking body for engagement in the respective recess of the carriage and that further comprises the locking block has two symmetrical about the longitudinal median plane second wedge surfaces, which cooperate with the first wedge surfaces of the locking body surface.
    The guide surfaces of the locking body lie on a large area of the walls of the Quemut, which significantly reduces the surface pressure and avoids local peaks. The fact that the locking body are elongated in the direction of Quemut, their contact surface is significant 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 highly explosive ammunition. Favorable force and friction conditions prevail when the first and the second planar wedge surface of the locking body encloses an angle with the longitudinal center plane, optimally 45 degrees.
    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, also optimal 45 degrees.
    In an advantageous embodiment, 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, and the locking block is fixed at its head facing away from the bottom side by means of a second Quemut relative to the housing in the longitudinal direction. This ensures a defined assignment of the components involved in the locking in the vertical direction and allows the locking block to be slightly adjusted in the transverse direction. This ensures a uniform distribution of the forces acting on the two locking bodies.
    In an advantageous embodiment, the locking block forms a horizontal plate on the underside of the second wedge surfaces facing away from the head, which partially overlaps the locking bodies. The plate holds the locking bodies in the groove, which is also advantageous when assembling the gun. The plate may thus act in a manner similar to a waist of the pinch rollers in the prior art, if such an effect is desired. As a result, then the entire height of the locking body for the guide surfaces is available.
    It is within the scope of the invention that this locking system can also be used in rifles and submachine guns.
    In the following the invention will be described and explained with reference to figures. They show:
    1 shows a vertical longitudinal section through a pistol according to the invention, FIG. 2 shows an axonometric view of the latch from below, FIG. 3 shows a cross section according to FIG. 2 in FIG.
    4 shows an enlarged view according to IV in Figure 2,
    5: the gun in a first operating position seen from below (b)), FIG. 6: As in FIG. 5, in a second operating position,
    FIG. 7: As in FIG. 5, in a third operating position,
    8: A variant of FIG. 2.
    In Fig. 1, the housing of a gun according to the invention is indicated by dashed lines and designated 1. In full line, the section through the relevant erfindungsrelevan-th parts in the longitudinal center plane to see. On the housing 1 is a running 5 * ♦ * * * · *** * a * 4 ψ * * * · i · · ι ·.,; slide 2 guided in guides 34 in the longitudinal direction displaceable. In the carriage 2, a barrel 3 is guided displaceably in the longitudinal direction. At its front end, the carriage 2 forms a pair of glasses 7, which is penetrated by the barrel 3 and on which a closing spring 8 containing a closing spring rod engages under the barrel 3. 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 because it is immaterial to the invention.
    In the housing 1, 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 run 3. The lock is summarily denoted by 10. The housing-fixed part of the lock 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 the abutment for the closing spring 8, the back surface 16 of the locking block is supported on the guide block 6 from. The bolt 11 is designed here pivotable about one of the pins 14 as a Zerleghebel.
    Fig. 2 and 3 shows the locking device 10 according to the invention in an oblique view and in the longitudinal direction turned by 180 degrees, 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 (pictured above) a retaining groove 17, in which the latch 11 (see FIG. 1) engages and symmetrical to the longitudinal center plane two wedge surfaces 21. The rear part of the barrel. 3 forms a running head 22 with at its bottom a transverse groove 23. In the Quemut 23 is on both sides each a Verrieglungskörper 24, 25 out in the transverse direction.
    The head 22 of the barrel 3 is guided in the longitudinal direction 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 this case, each groove and strip can be arranged in one or the other of the components. In Fig. 4, the components of Fig. 2, that are the housing-fixed locking block 20, the head 22 of the sliding barrel 3, in the Quemut 23 displaceable locking body 24, 25 and the carriage 2 with the recesses 28, enlarged in plan view ,
    The locking block 20 has symmetrical with respect to the longitudinal center plane of the side walls 18 converging to the rear first wedge surfaces 21, which with the longitudinal direction at an angle 39, preferably 45 degrees. At 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 Quemut 23, which forms straight flat vertical surfaces for guiding the locking body 24,25. Significant forces are entered by the locking bodies 24, 25 over these surfaces, the surface pressure not assuming excessive peak values thanks to the surface contact according to the invention. The transverse groove 23 is interrupted by a central elongated channel 26 in which the locking block 20 is guided. The channel is bounded at its rear end (in the image on the right) by a transverse surface 33. This serves as a stop against 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. There is an angle 39 between the second wedge surface 38 and the longitudinal direction, preferably this is 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 inclined transition zone 42 is here a plane which includes an angle 43 with the longitudinal direction, preferably 45 degrees.
    The carriage 2 has on the inside of its side walls on both sides recesses 27 which cooperate with the Verriegelungskörpem 24, 25. The recesses 27 have a the engagement surfaces 40 of the locking body 24, 25 corresponding shape. Here it consists of a circular cylindrical zone 41 and an inclined, for example, level, transition zone 42. The transition zone may be flat, but need not. At a corresponding angle 43, it reduces the force and friction required for unlocking.
    5 to 7 show three different operating positions of the lock 10, by means of which the mode of operation will now be explained,
    Fig. 5 shows the device locked and ready to fire. The carriage 2 and the barrel 3 take their foremost position. In this, the head 22 of the barrel 3 is located on the impact plate 5 and the back surface 16 of the locking block 20 abuts the head 22 of the barrel 3 (see 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.
    If a shot is fired, then first slide 2 and 3 barrel against the force of the closing spring 8 back (in Fig. 6 to the right) pushed. The locking block 20 does not change its position with respect to the housing 1. As a result, the locking bodies 24, 25 are located further behind with respect to the locking block 20. They are no longer held by the side walls 18 of the locking block 20 in the recesses 27 of the carriage, between them are now the locking surfaces 32, whose distance from each other is smaller than that between the side walls 18. The locking body 24, 25 can thus inward - to each other - dodge.
    The common return of the carriage 2 and 3 barrel ends when the head 22 of the barrel 3 abuts against the stop 13 of the guide block 6 and stands still, see Fig. 1. Then moves only the carriage 2 further backwards. Due to the relative movement between the carriages 2 and 3, the locking bodies 24, 25 are pressed inward by the zones 45 of the recesses 27 in the carriages 2 until they bear on the latching surfaces 32. This is the unlocked position shown in FIG. It agrees with the enlarged in Fig. 4 representation.
    During further return of the carriage 2, the cartridge 12 is ejected in a known manner and the impact device 4 stretched. When the carriage 2 advances after reversing its motion, the positions of Figs. 5, 6 and 7 are reversed.
    Fig. 8 shows a variant of Fig. 2, of which it differs only in that the locking block 20 above the wedge surfaces 21 (dashed, because invisible here) forms a plate 120 which partially overlaps the locking body 24, 25, so they can not fall out of the Quemut 23 * v
