    FIREARM WITH A DEVICE FOR DISASSEMBLY

    Abstract
    A firearm, especially a pistol, having a receiver and a guide rail for a slide that has a barrel, a retaining spring, and a slide stop device, the firearm further including a disassembling lever that is rotatable in the receiver, configured so that when the lever is in one end position: a) an abutment of the slide abuts against the lever and cannot be moved further forward, b) a fully inserted magazine is in contact with the lever and prevents any rotation, and c) an upper surface of the lever lies opposite an edge of the slide. When the magazine is withdrawn and the slide is stopped by the slide stop device, the lever can be rotated to allow the forward movement of the receiver.

    Claims



    1-3. (canceled)

    4. A firearm, comprising: a slide having a barrel; a receiver, including a trigger mechanism; at least one guide rail for the slide; a slide stop device configured to retain the slide in its rear position on the slide; a retaining spring; and a firing pin mechanism connected to and configured to cooperate with the trigger mechanism; wherein the firearm further comprises a disassembling lever rotatable in the receiver about an axis of rotation extending transversely to the direction of the barrel, where the disassembling lever is rotatable between a first end position and a second end position; wherein when the disassembling lever is in the first end position: an abutment of the slide abuts against a rear edge of the disassembling lever as the slide moves forward under the action of the retaining spring and cannot be moved further forward; independently thereof a magazine fully inserted into the receiver is in contact by means of one of its sides with a front edge of the disassembling lever and prevents any rotation by the disassembling lever; independently thereof an upper edge or surface of the disassembling lever lies opposite a lower edge of the slide such that this prevents any rotation by the disassembling lever; and when the magazine is completely or partially withdrawn from the receiver and the slide is stopped by the slide stop device, the disassembling lever can be rotated into its second end position, with the result that once the connection between the trigger mechanism and the firing pin mechanism has been eliminated and the slide stop device has been cleared, the slide can be removed from the receiver either forwardly or forwardly and upwardly.

    5. The firearm of claim 4, wherein the lower edge of the slide is its upper slide path.

    6. The firearm of claim 4, further comprising a spring configured to urge the disassembling lever away from its second end position.

    7. The firearm of claim 4, wherein the firearm is a pistol.

    Description



    The invention relates to a firearm, in particular a pistol, having a device for disassembly, corresponding to the introductory part of claim 1 and to GB 151 196.

    BACKGROUND

    [0001] This printed specification dating from 1920 discloses a pistol in which, when the magazine is fully inserted, it urges a spring-loaded cam into a position in which it is not possible to disassemble the firearm. If the magazine is withdrawn from the body by at least a certain amount, the cam is rotated under the action of its spring such that it permits the slide to be removed. Here, rotation of the cam also has the effect that the parts of the trigger mechanism that are in the receiver, often called frame, disengage from the parts in the slide, the firing pin mechanism--something which is likewise necessary for disassembly. This becomes dangerous if there is still a round in the barrel and, when the magazine is withdrawn, the uncoupled firing pin mechanism fires a shot as a result of a knock to the firearm or similar.

    SUMMARY

    [0002] Pistols are conventionally disassembled in that a movable barrier, which limits the forward movement of the slide--synonymously called a breech block--under the action of the retaining spring, is moved out of the path of the slide. Once this is done, the slide may in principle be removed forwards. However, the term "in principle" here also covers the fact that the trigger mechanism that is in the receiver of the pistol must be disengaged from the part in the slide, which is called the firing pin mechanism (synonymously also the hammer mechanism) as a whole, in order not to obstruct removal. A vast range of measures are available for this, depending on the conditions imposed by the construction.

    [0003] Further conditions that need to be observed and are implicit in the term "in principle" are the conditions specified by the buyer or user, which may be of widely different types, and require for example that disassembly shall only be possible if there is no magazine in the body, and which may furthermore and independently thereof require that disassembly shall only be possible if the slide is held firmly in its rear position by a slide stop device, often called slide stop lever, and so on.

    [0004] Since these requirements are imposed entirely erratically, without any technical or other necessity, and result in numerous special forms of firearms having to be derived from a basic form, there is a need to provide a device of this kind that cumulatively fulfils all requirements of this kind.

    [0005] It is the object of the invention to provide a firearm, in particular a pistol, having a disassembly device of this kind.

    [0006] The present disclosure is directed to a firearm having the features listed in the characterising clause of claim 1. In other words, in a firearm having a slide stop device, the holding device for the slide (breech block) is mounted in the receiver as a rotary part and takes a form such that neither rotation of the inserted magazine nor of the mounted slide is permitted, independently of one another, the latter with the proviso that, in its stopped position, the slide does not hinder rotation.

    [0007] Thus, if in this position the magazine is withdrawn or has already been withdrawn previously, it is possible to rotate the holding part such that it no longer prevents forward movement of the slide. The separation of the trigger mechanism and the firing pin mechanism, which is likewise necessary, may be performed independently thereof, according to the design and basic construction of the pistol, and in different ways, for example by lowering the trigger mechanism or axially clearing the firing pin mechanism; there are examples of both variants in the prior art that those skilled in the art who have knowledge of the invention can readily adapt to the respectively applying case, if indeed an adaptation of this kind is at all necessary and feasible under the circumstances.

    [0008] Even though the text below explains the invention in terms of a pistol, and pistols are the most frequent area of application, use with other firearms is nonetheless entirely possible in an advantageous manner.

    I believe this is the rear takedown lever that’s on the Glock 46. The 46 does not have a slide lock under the rotating barrel like all of the other glocks we have seen before.

    That’s my guess.
