Definitions

  • the invention is based on a firearm, in particular a hand gun, according to the preamble of the main claim.
  • the lock is released shortly after the shot has been fired and after the projectile has left the barrel and, moreover, the breech slide including barrel has made a forward stroke counter to the firing direction.
  • the breech slide continues its way into the open position, whereby on the one hand the empty cartridge case is ejected and on the other hand a new cartridge with projectile and propellant charge into the cartridge chamber provided at the rear end of the barrel due to the now given distance between the cartridge chamber and the butt plate is slipped in when moving the breech block forward.
  • the rear barrel section in the region of the cartridge chamber has a reinforcement which forms a shoulder which interacts with an opening in the breech slide so that the barrel is firmly locked with the breech when fired. and after leaving the projectile the barrel must be pivoted downward with its rear end portion for unlocking, the reinforcement emerging from the opening, after which the locking slide can slide over this widening.
  • This unlocking movement is achieved by a backdrop located below the barrel, which, after covering a forward stroke, interacts with a corresponding counterpart in the housing so that the barrel is pulled downwards at the rear as the carriage and barrel move together and then unlocked.
  • the mutually facing transverse surfaces on the breech slide and barrel are relatively small in these known firearms, so that after firing the shot a high surface load arises, which is particularly disadvantageous because the material of the breech slide and in particular the barrel is relatively soft and which can lead to throws up to pinching and enlarged games.
  • the inclination of the barrel when firing means that the tilting moment on the weapon is increased due to the increased distance between the lines of action of the cartridge and the hand force of the shooter, which is noticeable when the weapon is struck higher.
  • a time-consuming reorientation is always necessary.
  • a certain disadvantage is that due to the inclined swivel of the barrel there must be a minimum distance between the barrel axis and the guide rod axis, which means that the trigger device with its pivot point or the finger point of attack is relatively far away from the barrel axis, which is the case when shooting due to the given Leverage ratio has an unfavorable effect.
  • the firearm according to the invention with the characterizing features of the main claim has the advantage that the barrel is not pivoted as in one of the marksmen preferred by target shooters because of their accuracy, which only work with a spring lock, and can therefore be guided axially exactly in the lock slide.
  • the relocation of the lock in the area of the guide rod offers the possibility of providing larger locking surfaces and thus reducing the surface pressure of the locking surfaces and / or using a hard material there that differs from the materials from which the barrel or the locking slide is made is made.
  • Another important advantage of the invention is to be able to choose the distance between the axes of the barrel and guide rod to be as small as possible in order to obtain a lower "Viesier line", which results in favorable handling and firing reliability of the weapon.
  • Locking slides can be used for various types of pistols, such as compact pistols in the 9 mm para range and magnum versions.
  • the locking and unlocking is accomplished by an interaction of the cantilever part in the region of the guide opening with the front end section of the guide rod.
  • the arrangement in the front end section of the guide rod relieves the load on the rear end section, which is already burdened by various tasks, and the entire closure area. Since the guide rod is guided in the guide opening of the cantilever part, there is sufficient space for the design of a locking device.
  • the advantages lie above all in a compact, space and weight-saving construction in which the locking device is arranged at a distance from the cartridge chamber and as a result there is no weakening of the barrel or locking slide.
  • a locking device can be designed which uses hard materials appropriate to the application, without having to weaken the barrel or the locking slide. As is well known, those with high toughness are chosen for the running material and less such great hardness.
  • the locking device consists of a bayonet lock connection which is open towards the front and which is located between the guide rod and the guide opening and in which a radial pin arranged on the guide rod fits into the corresponding one Locking grooves engage so that a relative displacement in the axial direction between the locking slide and the barrel is prevented. Only after turning the guide rod does the radial pin enter the section of the locking groove running in the weft direction, so that a relative displacement in the longitudinal direction between the locking slide and the barrel is made possible.
  • These interlocking bayonet fitting parts can be made of hard material without any problems, whereby, due to the design, relatively large effective surfaces between the radial pin and the groove wall can be produced.
  • the radial pin itself can be designed as a pin connected to the guide rod. However, a plurality of such radial pins are preferably provided in the form of preferably centrally symmetrically arranged lugs of rectangular cross section.
  • the guide opening having the shape of a paw cross (iron cross, knight's cross) in the end view from above.
  • a paw cross iron cross, knight's cross
  • the shape can also have only three or two radial pins.
  • the locking takes place via a spline between the guide opening and the guide rod, with an annular groove which is present in the end section and allows rotation for unlocking.
  • a spline provides smooth axial guidance for the relative displacement between the locking slide and barrel, which, however, only starts when the preliminary stroke has ended and the locking device by rotating the relative displacement between locking slide and barrel or which allows the guide rod coupled to the barrel.
  • the lead spring is arranged coaxially on the guide rod and acts as a "captive spring” via support shoulders on the end sections of the guide rod.
  • the spring can be caught on the guide rod because it has a relatively large length - also with the advantage that due to the relatively long length, a spring of certain characteristics can be easily accommodated.
  • a support is provided on the front end section of the guide rod and corresponding designs from the ring for the locking device.
  • the ring can be arranged in a wide variety of ways on the end section of the guide rod, the wedges of the guide opening or a support ring arranged behind the cantilever part compressing the spring when the guide rod is displaced in the guide opening of the cantilever part.
  • the ring can also be pressed as a press-in bushing of hard material onto the relatively soft material of the guide rod, wherein the guide rod can advantageously consist of stainless steel.
  • the radial pins are incorporated into the radial region of such a pressed-on bushing and possibly also in a bushing pressed into the cantilever part.
  • the ring can also be designed as a spring plate displaceable on the guide rod.
  • the guide rod is in two parts in the longitudinal direction formed, wherein a damping spring and / or a stop is arranged between the parts coaxially to the return spring.
  • a stop is arranged coaxially with the return spring between the two parts of the guide rod.
  • the damping spring can be dispensed with, particularly in the case of small calibres, and is advantageous in terms of production costs.
  • a turning device is provided on the rear end section of the guide rod and in the surrounding housing, by means of which the guide rod is rotated for unlocking after the advance stroke has been completed.
  • a clasp which can be inserted into the weapon housing and whose inner surface faces the guide rod serves as the surrounding housing of the rotating device. It is also true here that this clasp can consist of a harder material corresponding to its special task and in particular can take on both managerial and constructive tasks.
  • a turning hole is used transversely to the guide rod and transversely rotated to the longitudinal axis and a pin bolt penetrating it and mounted in the surrounding housing. During the forward stroke, the spring guide rod is thus rotated by sliding along the coiled wall of the elongated hole on the surface of the pin bolt.
  • bundles of rings on the guide rod in the area of the winding of the elongated hole as material reinforcement in these areas of particularly high material stress since here the pin bolt guides the guide rod as a result of its forward movement into and out of the rotary movement. Furthermore, the collar and the resulting annular groove serve to guide the guide rod and for the axial connection of the barrel and the guide rod.
  • radially arranged link pins are arranged at the rear end of the guide rod and correspondingly in the surrounding housing the rotating movement of the guide grooves producing link grooves, the link pins serving as a support shoulder for the forward spring.
  • two guide pins are advantageously sides of the side facing away from one another
  • the surrounding housing can be formed by a part which is inserted specifically into the weapon housing, but also by the weapon housing itself. This is a question of the structural design in the case of either a particularly narrow construction of the weapon or the use of special materials is taken into account. Since the diameter of the guide rod can in any case be smaller than that of the barrel, which determines the overall width of the weapon with the breech slide, there is generally sufficient space for the arrangement of an additional part receiving the link groove.
  • a barrel hook engaging behind the guide rod, which is secured against rotation with respect to the housing and serves as a stop for the guide rod which can be rotated relative to it.
  • a hook is known per se (DE-OS 1703417) but not in the manner of an interaction with the guide rod in which the latter can be rotated independently.
  • a pin or a bore is arranged on the stop side of the barrel hook or at the rear end of the guide rod, which pin corresponds to a central axial bore or a central axial pin of the guide rod or the barrel hook.
  • Such a pin or such a bore is used primarily for the rotation of the guide rod.
  • the barrel hook has a socket which is inserted over the barrel and is firmly connected to it.
  • the combination of two materials with different properties can be advantageous in terms of function and manufacturing costs, especially for small calibers.
  • an elongated hole or a path-limiting recess is provided on the barrel hook, which interacts with a retaining bolt anchored in the housing. Because the barrel has an axial guide, the recess delimiting the stroke of the barrel can also be designed to be open at the bottom. Such a design is cheaper to manufacture and more compact than one with an elongated hole.
  • the retaining bolt serves as a slide lock and trigger bearing, as a result of which a compact design and low production costs are achieved.
  • the axial journal has a coiled flattening and the corresponding axial bore overlaps with the recess or the elongated hole on the barrel.
  • the barrel is axially guided only in the region of the side facing away from the barrel opening, as a result of which the barrel can vibrate freely when the shot is fired.
  • a free-swinging barrel increases the accuracy of the firearm.
  • a leaf spring located in the weapon housing holds the trigger lug and / or pushes the interrupter forward and upward, as a result of which a compact design and low production costs are achieved.
  • Figure 1 shows the first embodiment in partial longitudinal section.
  • Fig. 2 guide rod in side view of FIG. 1;
  • Figure 3 shows the second embodiment in partial longitudinal section.
  • FIG. 5 shows a cross section along the line III - III in FIG.
  • Fig. 1 and Fig. 3 the two exemplary embodiments shown are shown in a ready-to-fire, locked state.
  • spatial terms such as “bottom”, “top”, “rear” and “front” refer to the normal firing position of the weapon with a horizontal selenium axis in the following description, the firing direction pointing "forward".
  • a locking slide 2 is guided in a longitudinally displaceable manner on a conventional sliding guide of a weapon housing 1 known per se.
  • a barrel 3 is guided axially displaceably thereon, which also has an additional guide in a recess 4 in the weapon housing.
  • a pre-spring 5 provided for braking and advancing the breech after the shot.
  • This forward spring 5 is arranged coaxially on a spring guide rod 6, which is mounted with its front section in a guide opening 7, while its rear section is mounted in a corresponding recess 8 of the weapon housing 1.
  • the guide rod 6 is axially rotatably connected to the rear end portion of the barrel 3 at the rear end in the region of the hook 9 by two ring collars 53, which serve to guide them.
  • a slightly coiled elongated hole 10 is provided transversely to the longitudinal direction, through which a pin bolt 11, which is mounted in the weapon housing 1, protrudes, so that when the guide rod 6 is axially displaced to the rear, the latter undergoes a rotation corresponding to the spiral.
  • a downwardly projecting cantilever part 12 is arranged on the closure slide 2, in which the guide opening 7 of the guide rod 6 is arranged. Furthermore, a damping spring 56 is arranged on the guide rod in this exemplary embodiment, in order to alleviate the load or recoil that occurs after a shot.
  • a stop ring 13 On the side of the guide rod 6 facing away from the cantilever part 12 there is arranged a stop ring 13 which limits the stroke of the barrel 3 and thus also the guide rod 6 and on which the damping spring moves to limit the stroke.
  • the guide rod 6 In the shown closed position of the weapon, ie the shown rotational position the guide rod 6, the inner toothing 14 and the outer toothing 15 lie one behind the other in such a way that they do not engage in the handlebar and when the locking slide 2 is moved to the rear, the guide rod 6 is taken along and through the elongated hole 10 and pin bolt 1 1 is rotated, after which the internal toothing 14 and the external toothing 15 mesh, so that the guide rod 6 can be pushed with its front end through the guide opening 7.
  • Fig. 2 shows the elongated hole 10 in the guide rod 6, here a material reinforcement of the guide rod in the form of two ring collars 53 in the areas of particularly high material stress, i.e. in which the pin bolt 11 the guide rod 6 due to the coiled elongated hole 10 from its translational movement leads to the rotary movement. Furthermore, the ring collars are used to fix and guide the guide rod and its axial positive connection with the barrel.
  • the slide 2 As soon as after the shot is fired and due to the recoil, the slide 2 is moved backwards, it takes the run for a predetermined stroke through the elongated hole 10 and the pin bolt 11 via the guide rod 6 and the ring collars 53, after which, after corresponding rotation of the Guide rod 6 pushes the damping spring 56 onto the retaining ring 13 and, due to the given unlocking in the area of the internal toothing 14 and the external toothing 15 of the cantilever part 12 via the guide rod 6 and taking the tension spring 5 with it or tensioning it, the locking slide continues the way backwards into its open position .
  • the empty cartridge is ejected and a new cartridge is inserted into the barrel.
  • a straight toothing 16 is present, which during the entire stroke of the locking slide 2 and after unlocking with the internal toothing 14 in the Guide opening 7 combs.
