Definitions

  • the invention relates to a self-loading weapon according to the preamble of claim 1.
  • Such a weapon is known from the Czechoslovak pistol CZ 1922 in 6.35 mm caliber.
  • the cartridges are transferred individually from a supply, such as a magazine or cartridge belt, to the cartridge chamber.
  • a supply such as a magazine or cartridge belt
  • they are first brought into or from the storage in a transfer position and from there, for example from the breech, pushed into the cartridge chamber.
  • the section of the weapon barrel containing the cartridge chamber can be designed as an integral part of the barrel or, as known from revolver weapons, as a separate component.
  • the number of transfer positions is mostly due to the type of storage. For example, there is Zigzag magazines with two transfer positions next to each other.
  • the transfer position (s) are usually not immediately behind the weapon barrel or the cartridge chamber. Instead, they are often arranged below the cartridge chamber or offset laterally (such lateral displacements are absolutely necessary if several transfer positions are provided next to each other).
  • a cartridge must travel a design-related intermediate distance between a transfer position and the cartridge chamber.
  • the position of the cartridge that is too low or laterally offset must be corrected to such an extent that it can be inserted into the cartridge chamber.
  • the cartridge in addition to a movement in the longitudinal direction of the weapon, the cartridge must also make a movement transversely to it, i.e. be moved in the transverse direction of the weapon and / or pivoted sideways. The latter means that in many cases the cartridge is in an inclined position when it reaches the weapon barrel, more precisely when its tip slides into the chamber. The cartridge is then aligned horizontally by pushing it further into the cartridge chamber.
  • the surface of the feed ramp has one or more guide grooves in which the cartridges are guided from their transfer position into the cartridge chamber. They slide, for example, from a lower position (relative to the chamber) in a slightly inclined position so that their tip "dips" exactly into the chamber.
  • the invention is based on the object of specifying a further possibility of providing a reliable cartridge feed for a multi-loading weapon.
  • the invention solves this problem with the subject matter of claim 1, that is to say with a weapon barrel of the type mentioned at the beginning, in which the guide element is arranged essentially where the intended feed movement of the cartridges in the transverse direction of the weapon ends during the loading process.
  • the guide element according to the invention thus limits the transverse movement of the cartridges on their way from the transfer position into the chamber.
  • it In relation to the central axis of the cartridge chamber, it is arranged essentially on the side opposite the transfer position.
  • the guide element according to the invention thus has a different function than the feed ramp known from the prior art.
  • the latter creates a physical transition for the cartridges from the transfer position to the cartridge chamber.
  • the guide element according to the invention counteracts a transverse movement of the cartridges that goes beyond the intended dimension, for example, setting them up (so-called pikes). Excessive transverse movements can lead to twisting and thus jamming of the cartridges during the loading process and, in particular, can occur with multi-loading weapons that have only simple transitions, such as the magazine lips or cutouts mentioned at the beginning.
  • the weapon barrel according to the invention is therefore particularly advantageously used in multi-load weapons in which - for cost or manufacturing reasons, for example - precise transitions have to be dispensed with.
  • the susceptibility to failure of such weapons during the loading process can then be significantly reduced with the aid of the invention.
  • the weapon barrel according to the invention is also suitable for increasing the robustness of the multi-load weapon even further in the case of precisely designed transitions (for example in the manner of the solution mentioned by the applicant).
  • the invention can in principle also be used advantageously for weapons in which the transfer position is immediately behind the weapon barrel or cartridge chamber. With such weapons, a transverse movement of the cartridges is not provided and is therefore not desired. Such undesirable transverse movements of the cartridges can then be prevented by the guide element according to the invention.
  • the present invention deviates from the traditional design of known gun barrels. So far, the area has been sought Keep as clear as possible before taking up the cartridge chamber in order to ensure that the sleeve ejection is as trouble-free as possible. It would have been expected when using the guide element arranged according to the invention that an increased number of loading inhibitions due to jamming during sleeve ejection would have to be accepted. However, initial practical tests have shown that this is not the case, but that the advantages of the invention come into play without negative side effects.
  • the weapon barrel according to the invention can in principle be used in any type of multi-load weapon in a conventional design. In individual cases, however, it may be advantageous or necessary to constructively adapt individual components of the multi-load weapon to the new weapon barrel. Therefore, in addition to the weapon barrel, the invention also relates to a multi-loading weapon, in particular a self-loading weapon, with such a weapon barrel.
  • the guide element according to the invention can be designed as a separate component and attached to the weapon barrel via a fixed or detachable connection.
  • the guide element preferably represents an integral part of the weapon barrel (according to claim 2), that is to say it is produced with it from a block of material.
  • the transfer position (s) of the cartridges are located below the cartridge chamber. Therefore, in a preferred embodiment, the guide element is arranged above the cartridge chamber (according to claim 3). Likewise, in the case of multi-loading weapons in which the transfer position (s) is arranged above the cartridge chamber, it is expedient to arrange the guide element below the cartridge chamber.
  • the guide element can also be arranged such that its relative position, as seen in the circumferential direction of the cartridge chamber, is offset from a pull-out element attached to the breech (according to claim 4). In this way it is ensured that the function of the pull-out element, for example a pull-out claw, is not impaired by the guide element. At the same time, the guide element is therefore usually not in the ejection direction of the sleeves.
  • the guide element can also be designed in several parts.
  • a plurality of guide elements can also be provided, which are then preferably distributed over the circumference of the tube.
  • the weapon barrel according to the invention is in principle suitable for advantageously supporting any type of cartridge feed of known multi-loading weapons.
  • a feed element is additionally provided which extends in the direction of the rear weapon part, is arranged essentially opposite the guide element with respect to the central axis of the cartridge chamber, and is intended to cooperate with the guide element when guiding the cartridges (according to Claim 5).
  • the feed element is preferably designed as an integral part of the weapon barrel.
  • the feed element is preferably further designed such that further means for guiding the cartridges on said intermediate section are no longer required in the case of the multi-loading weapon in question.
  • the cartridge feed is then accomplished solely by the interaction of the feed element with the guide element according to the invention.
  • the guide element and / or optionally (if present) the feed element are designed in such a way that his / her inner surface (s) at least with respect to the central axis of the cartridge chamber sections run obliquely in such a way that the distance of the inner surface (s) to the central axis decreases towards the front (according to claim 6). It is advantageous if the inner surface (s) flow smoothly into the inner wall of the cartridge chamber. If a feed element is present, the inner surfaces of the two elements preferably converge in a wedge shape.
  • the guide element and / or, if applicable, the feed element is configured in such a way that its inner surface (s) has (have) a cross-section (s) in the form of a segment of a circle, ie is / are curved, at least in sections.
  • the curvature of the circle segment (s) preferably corresponds to the radius of the cartridge chamber (according to claim 7).
  • the inner surfaces of the guide element and the feed element can also converge in a conical shape, that is to say they can each be designed as a segment of a common funnel.
  • the cone shape can then advantageously be worked on during the turning operation on the weapon barrel.
  • the guide element according to the invention and the associated feed element are primarily intended to ensure a cartridge feed that is as trouble-free as possible.
  • the guide element in particular in interaction with the feed element, is also suitable for closing the breech (or possibly breech head) when closing the cartridge chamber in relation to it to center. Therefore, the applicant also reserves independent protection for a weapon barrel according to claim 1, which fulfills the said centering function and preferably also has one or more features of claims 2 to 7.
  • the design of the closure must then be adapted so that the feed element can fulfill the centering function.
  • the barrel also apply in full to the multi-loading weapon according to the invention, namely a multi-loading weapon, in particular a self-loading weapon, with a weapon barrel, in which the cartridges are fed to the weapon barrel during the loading process and thereby move in the longitudinal and transverse directions of the weapon, and in which the weapon barrel has a cartridge chamber for receiving the cartridges and a guide element adjacent to the cartridge chamber, the guide element extending in the direction of the rear weapon part and being designed such that it guides the cartridges and is arranged essentially where the intended transverse movement the cartridges end while charging.
  • Fig. 1 shows a (only partially shown) barrel 3 of a self-loading weapon, not shown, with a cartridge chamber 5 and a (not shown) projectile bore.
  • the cartridge chamber 5 is located in the rear section 1 of the barrel 3 and opens out into the projectile bore so that the central axis of the cartridge chamber 5 corresponds to the core axis of the barrel 3.
  • the cartridge chamber 5 is used to hold cartridges (not shown).
  • the barrel 3 also has a guide element 7 which sits on an end face 9 of the barrel 3 and is an integral part of the same.
  • the guide element 7, which is referred to below as the "guide nose”, is arranged above the cartridge chamber 5 and extends (in the longitudinal direction of the weapon) to the rear.
  • the guide lug 7 has an inner surface 7a which is slightly curved in accordance with the radius of the cartridge chamber 5 and merges smoothly into the cartridge chamber 5 in a slight incline.
  • the barrel 3 is equipped with a feed element 11, which is referred to below as the "feed ramp".
  • the feed ramp 11 has an inner surface 11a which is slightly curved in accordance with the radius of the cartridge chamber 5, seen in the longitudinal direction essentially stepped into two differently sloping sections 11a 'and 11a' 'and merges smoothly into the cartridge chamber 5.
  • the barrel 3 has a cutout 13 for a pull-out claw (not shown) of the lock belonging to the barrel 3 (not shown).
  • the radii of curvature of the inner surfaces 7a and 11a correspond to those of the inner diameter of the cartridge chamber 5 in order to create the most harmonious possible transition between the inner surfaces 7a, 11a and the cartridge chamber 5. This ensures trouble-free insertion of the cartridges into the cartridge chamber 5.
  • the two surfaces Due to the inclined configuration of the inner surface 7a and the front portion 11a 'of the inner surface 11a (the inclination is approximately 8 degrees with respect to the central axis of the cartridge chamber 5), the two surfaces continuously approach each other in the longitudinal direction of the weapon. They form a kind of "beak" for better absorption of the cartridges. Due to the curved design of the inner surfaces 7a, 11a, these additionally function as guide grooves in order to hold the cartridges in a straight line in the direction of the cartridge chamber 5.
  • the cartridge feed works in the present example as follows: after the case has been ejected, a new cartridge is pushed from the transfer position (not shown) in the direction of the cartridge chamber 5 by the reloading movement of the closure.
  • the relative position of the transfer position lies below the cartridge chamber 5, so that the tip of the cartridge runs onto the rear section 11a ′′ (the inner surface 11a).
  • the cartridge is thereby lifted and directed upwards in the direction of the cartridge chamber 5 by the slope of this section 11a ′′.
  • the cartridge tip hits the inner surface 7a (the guide lug 7) and thereby tilts with the tip down into a more horizontal position, in which it comes to rest on the first section 11a 'of the inner surface 11a and then fully inserted into the cartridge chamber 5 becomes.
  • An advantage of the barrel 3 according to the invention is thus that the interaction of the guide lug 7 with the feed ramp 11 allows the latter to be designed in a relatively simple manner without having to accept increased inhibitions of loading. With the same reliability of the weapon, this reduces the manufacturing effort and thus the manufacturing costs.
  • a guide element according to the invention such as the guide lug 7, is also advantageously used in known barrels or multi-load weapons with precisely designed feed elements, since this increases the robustness of the respective multi-load weapon against inhibitions of loading.
  • the guide lug 7 limits the transverse movement of the cartridges upwards, so that they cannot move further upwards than intended in the transverse direction of the weapon.
  • the guide lug 7 "catches" cartridges that threaten to miss the cartridge chamber 5 and guides them when they strike the inner surface 7a Direction of the cartridge chamber 5.
  • a cartridge feeder is created which directs the cartridges into the intended path and holds them there immediately after they have left their transfer position (s). Therefore, no further feed elements are required apart from the feed ramp 11.
  • the guide lug 7 can generally be made shorter than the feed ramp 11. From the example it can be seen that the guide element according to the invention generally takes up relatively little space as a result and therefore has practically no disruptive effect on other processes, in particular the sleeve ejection.
  • Fig. 3 shows the barrel 3 'in the installed position in a submachine gun 15 with the breech 17, which closes the cartridge chamber 5 from behind.
  • the breech 17 shown separately in FIG. 4 is displaceable in the longitudinal direction of the weapon stored and can thus perform a reload movement in a known manner when loading or after firing a cartridge.
  • the closure 17 has on its front surface 19, in addition to various other recesses (which are not to be explained in more detail here), a groove 21 which extends continuously from a point above a push floor 23 to the bottom of the closure 17 extends and serves as a clearance for the guide lug 7 and the feed ramp 11 (see also Fig. 3).
  • the function of the closure 17 is therefore not restricted and, particularly in this area, there is also no need to adapt the design to the newly designed barrel 3 '.
  • the example also shows that the longitudinal dimensions of the weapon generally do not have to be increased for the use of the invention.
