Case discharge device

Abstract

A case discharge device having a case ejector for ejecting a case or a misfire for a weapon having a bolt with a bolt head, wherein a munition is supplied to a weapon barrel of the weapon by the bolt and the case or the misfire is pulled out of the weapon barrel. The case discharge device is characterized in that, now, in the bolt head, there is situated a groove into which a case ejector which is static with respect to a weapon housing engages. During the return of the bolt, the case ejector which is static with respect to the weapon housing slides within the groove and engages on the bottom of the case in order to release the latter from the bolt and, after the release, discharge said case.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

(2) FIG. 1 shows a plan view of a breech head according to the invention;

(3) FIG. 2 shows a perspective illustration of the breech head in FIG. 1;

(4) FIG. 3 shows a perspective plan view of the breech head and the casing ejector;

(5) FIGS. 4 and 5 show an illustration of the casing ejection in a (schematic) plan view without a breech head.

DETAILED DESCRIPTION

(6) In FIGS. 1-3, a breech head of a breech 2 is identified by 1. The breech head 1 and the breech 2 are mounted in a weapon housing 22 and are guided therein. A casing extractor 3 is incorporated at the front end of the breech head 1, preferably laterally, in this case on the right-hand side as seen in the firing direction. The casing ejector 3 preferably has a semicircular flat shape 3.1. As a result, optimum engagement with a casing bottom 10, illustrated schematically in FIGS. 4 and 5, of a casing 11 is ensured. In operation, the casing extractor 3 acts on a groove 10.1 in the casing bottom 10 in order to extract the casing 11 in a known manner. The casing extractor 3 is preferably spring-mounted in the breech 2 or on the breech head 1. A firing pin 4 positioned centrally in the breech head 1 is only indicated in this case.

(7) A slot 5 is introduced into the breech head 1 laterally, on the left-hand side as seen in the firing direction and opposite the casing extractor 3. This slot 5 extends preferably along the entire length of the breech head 1. In this groove 5, a casing ejector 6 that is fixed to the weapon or is fixedly connected to the weapon housing 22 is guided. Said casing ejector 6 projects laterally into the slot 5 with its lug or its face 6.1.

(8) FIG. 3 illustrates a plan view of the weapon-side incorporation of the casing ejector 6, wherein the breech 2 is still in its locked (front) position. The ejection direction of the casing 11 (not illustrated in more detail here) is indicated with A. FIG. 3 also shows the incorporation of the casing discharge device with the casing ejector 6 and the casing extractor 3 in an only partially illustrated weapon 20. This weapon 20 has a barrel bundle with a plurality of weapon barrels 21, 21, 21 (only indicated), wherein only one weapon barrel 21 is locked with the breech 2 when a shot is fired. Provision is not made here for the weapon barrel 21, 21, 21 to be changed after every shot. Rather, a barrel change takes place when the weapon barrel 21 drops below a predetermined temperature, for example, (barrel wear) or a firing condition is determined (dud; lack of weapon recoil on account of a lack of firing) etc.

(9) The illustration chosen here shows what is known as the transport position, in which none of the weapon barrels 21, 21, 21 is in front of the breech and the latter is also not tensioned. As a result, the transport safety is increased.

(10) The casing ejector comprises a face 6.1 which engages in the slot 5. The diameter or the height/thickness of the face 6.1 and also the face 6.1 itself is coordinated with the width and depth of the slot 5. In the preferred embodiment according to FIGS. 4 and 5, this face 6.1 has a recess 6.2, which for its part is coordinated with the diameter of the casing 11. By way of the recess 6.2, a lateral face 6.3 is formed on the casing ejector 6, said lateral face 6.3 serving to securely hold the casing 11 before the actual ejection during the breech movement toward the rear. A slope 6.4 then supports the ejection of the casing 11.

(11) The sequence of casing ejection can be described as follows:

(12) During its forward movement, the breech head 1 carries along a munition (not illustrated in more detail) and guides the latter into the shell chamber of a weapon (not illustrated in more detail). In the process, the breech head 1 is guided along the (stationary) casing ejector 6 fixed to the housing and carries along the munition. The casing ejector 6 is located at the rear stop of the slot 5 (FIG. 3) when the breech 2 is locked in its front position with the weapon barrel 21. After a shot has been fired, the breech 2 and breech head 1 are moved toward the rear, the casing (dud) is also moved out of the weapon barrel 21 in a known manner by the casing extractor 3 at the breech head 1. As the breech head 1 slides back, the latter slides with its slot 5 along the recess 6.1, wherein the casing 11 also passes into this region of the casing ejector 6 (FIG. 4). The lateral face 6.3 of the casing ejector 6.1 encloses the casing 11 on one side and in a somewhat planar manner 6.3, corresponding to the thickness of the casing ejector 6. As a result of further movement of the breech head 1 (FIG. 5), the rear slope 6.4 now acts on the casing bottom 10 and pushes the casing 11 in the opposite direction A, i.e. to the right as seen in the firing direction. In the process, the casing 11 is tilted away, such that the casing extractor 3 slides out of the groove 10.1.

(13) A new shell can be presented to the breech head 1.

(14) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
