Definitions

• the invention relates to pistols which consist of a handle, a slide which can be displaced on it in the firing direction and a barrel which can be locked with the barrel, first locking means on the barrel, second locking means on the barrel and unlocking in the handle. means are provided.
• the barrel has elevations on its upper side which, when locked, fit into corresponding shapes in the slide.
• the barrel On the underside, the barrel has an attachment with a backdrop, into which a barrel stop provided with a control profile engages.
• the interplay of scenery and control profile pulls the rear part of the barrel downwards and unlocks it.
• the backdrop and control profile are difficult and expensive to manufacture with the required precision. They take up space under the barrel, which means that the barrel lies considerably above the shooter's hand, which results in an increased tilting moment when firing. Above all, however, the reaction forces from the eccentric force attack and from the tilting movement of the barrel are disruptive, they complicate handling and impair accuracy.
• the aim of the invention is to counteract these disadvantages.
• a generic pistol is to be created, the locking of which is simple, cheap and space-saving, and which results in a pleasant, linear recoil behavior.
• the first locking means is a projection on the outer contour of the barrel with a first inclined surface facing forwards
• the second locking means is a lever which is pivotably guided in the carriage and has a claw with a second inclined surface facing backwards, which cooperates with the first inclined surface
• the unlocking means is a stop in the handle, which cooperates with a nose of the barrel.
• the angle of inclination of a normal to the inclined surfaces to the firing direction and the position of the pivoting pole of the lever are chosen so that when the barrel strikes the stop and the barrel slides on, the inclined surfaces can slide against each other and the lever is pivoted against the force of a spring that the claw releases the projection on the outer contour of the barrel and thus the carriage for the continued backward movement.
• the lever does not need a compulsory guidance, it is only pressed on by a spring without any additional control surfaces or baffles being thrown quickly into the opened, unlocked, position by the kinetic energy of the returning slide.
• the lever can be pivoted about a fixed axis or guided in some other way. In any case, the space required by the lever across the direction of the shot is small, which benefits the external dimensions of the pistol.
• the angle of inclination of the inclined surfaces with respect to the direction of movement of the barrel should be greater than the angle of friction when there is friction between the two inclined surfaces.
• the friction factor ⁇ is equal to the tangent of the friction angle.
• the lever is preferably a two-armed lever, the axis of rotation of which lies behind the inclined surface, the arm which is directed towards the front carries the claw and the arm which is directed towards the rear presses a spring outwards, the spring is a leaf spring and is the projection on the outer contour of the barrel arranged at the rear end. This gives you a compact design and short power flow paths.
• a further stop is provided in the handle, which also interacts with the nose of the barrel, the clear distance in the longitudinal direction between the stop and the further stop being greater by an amount than the length of the nose is. This amount determines in the simplest way the return path of the barrel until unlocking, which can be very short thanks to the essence of the invention. If this additional stop is designed to be retractable, it serves as a disassembly lock, after opening the barrel can be pulled out.
• the barrel has two lateral projections, a pivotable lever is provided on each side and the unlocking means are arranged under the barrel. Due to the symmetrical lateral arrangement of the levers, the locking forces also act symmetrically on the barrel and the vertical distance of the barrel axis from the shooter's hand is minimized. Since the levers are flat components, the gun does not get wider. A particularly slim design is achieved if the levers are located in the side openings in the slide.
• Fig. 1 A pistol according to the invention in side view
• Fig. 2 Detail from Fig. 1, enlarged and partially sectioned
• Fig. 3 Section III-III in Fig. 2
• Fig. 4 Cross-section according to IV-IV in Fig 3
• Fig. 5 Detail V in Fig. 3, enlarged.
• a pistol according to the invention is only roughly indicated in FIG. It consists of a handle 1, a carriage 2 and a barrel 3.
• the housing 6 goes down into a trigger guard 5 and into the handle 7.
• the barrel 3, only hinted at, is guided in the carriage 2, borrowed.
• the carriage 2 is a part of approximately rectangular cross section which extends over the length of the entire pistol. It consists of a left side wall 7, a right side wall 8 and a top wall 9 (see FIG. 4). In its rear part it contains a locking piece 10 which contains, for example, a firing pin with the associated parts (not shown). One sees only a striker pin 12 and a stud 13 which is actuated via a trigger mechanism 14 which is only indicated. At its front end, the closure piece 10 forms a butt plate 11, against which the barrel 3 rests in the locked state.
• the carriage 2 has a front plate 15 guiding the barrel 3, on which a closing spring 16 is supported at one end. Its other end rests on an abutment 17 fastened in the handle.
• a lever 20 is mounted in the side wall 8 of the carriage 2, in the exemplary embodiment shown an identical lever 20 'is provided in the other side wall 7. To reduce the width of the slide, these levers are arranged in openings in the side walls 7, 8 with approximately the same contour.
• the levers 20, 20 ' are two-armed levers, the pivot axis 21 of which is mounted vertically in the ears 26 of the slide.
• the front arm 22 (and 22 ') forms an inward claw 24 at its end.
• the rear arm 23 is urged outward at its end by a leaf spring 25 (and thus the claw 24 thus inward), the other end of which at one inner extension 27 of the carriage 2 is held.
• the ears 26 and projections 27 also serve to hold the closure piece 10 here.
• the barrel 3 has a cartridge chamber 28 at its end facing the butt plate 11 and projections 29, 29 'on the outside on the side. These projections 29 interact with the claws 24 in the locking of the carriage 2 and the barrel 3 in a manner to be described.
• a single lever would suffice for locking; in the exemplary embodiment shown, two of them, symmetrically one on each side, are arranged.
• the other organ required for locking or unlocking is a nose 32 on the underside and near the rear end of the barrel 3, which nose 32 cooperates with a stop 33 fixed to the housing.
• the stop 33 protrudes from a bridge 37 arranged in the handle 1, in which a further stop 34 is guided vertically displaceably further forward.
• the stop 34 can be withdrawn by means of a disassembly lever, not shown, in order to be able to pull off the barrel and subsequently disassemble the pistol. It can be seen that the length of the nose 32 is less than the distance between the stop 33 and the further stop 34. The difference 35 is the distance that the run 3 travels backwards with the carriage 2 until, when the stop 33 is reached, the connection between carriage 2 and 3 is unlocked. Finally, an ejection claw 36 can also be attached in the top wall 9 of the slide 2.
• the projection 29 has a first inclined surface 40 in the front weft direction and a first contact surface 44 in the weft direction.
• the claw 24 has a second inclined surface 42 in the weft direction and at the front a second contact surface 46.
• the two inclined surfaces 40, 41 here are parallel flat surfaces, the surface normal 39 of which forms an angle 41 with the running axis. But you could also be spherical.
• the angle 41 must be greater than the friction angle, the tangent of which is the coefficient of friction ⁇ between the two inclined surfaces 40, 41. It is assumed that the pivot or the pivot axis of the lever is approximately the same distance from the plane of symmetry of the pistol as the inclined surfaces.
• the effect of the two inclined surfaces is as follows: if the barrel thrown back against the direction of the shot by the recoil is suddenly stopped with its nose 32 at the stop 33, the barrel sled 2 thrown back together with the barrel 3, because of its inert mass, tends to do so to continue its movement. Since the lever 20 is connected to the sliding carriage 2 in the rotating pole 21, a force 52 acts on it, which is broken down on the inclined surfaces 40, 41 according to the angle 41 into a normal component and a tangential component. If the tangential component of this force is greater than the frictional force between the two inclined surfaces, the claw 24 is pivoted outward very quickly against the force of the spring 25 until it releases the projection 29. Now the carriage 2 can move further back.
