Description

The The invention relates to a propellant charge container for the protection of the Guiding union of a mortar shell arranged, horseshoe-shaped formed propellant charge body against damage and environmental influences, wherein the propellant charge bodies one central opening each and a passing into the central opening Radial slot for pushing the propellant charge body on the Shaft of the grenade exhibit.

at mortar shells usually horseshoe-shaped propellant bodies are used, in each needed Number to be postponed to the Leitwerkschaft. Depending on the target distance can be provided a different number of propellant charge body then each by appropriate choice of the central opening and of the radial slot are clamped on the guide shaft.

at rough handling or improper transport can the propellant charge bodies damaged be, fall off the shaft or twist against each other. In addition, can it comes through rain and splash water to moisten the propellant charge body.

If you want to provide the propellant charge for protection against the environmental influences with a protective cover, it must be removed shortly before loading the mortar shell into a corresponding weapon (for example, in a shell mortar) again. It should be noted that for the removal of the protective cover after receiving a fire command only very little time is available, usually 0.5-2 s). The DE 26 37 609 A1 shows a protective device for the propellant charge body of a projectile.

Of the Invention has for its object to provide a propellant charge protection container which offers improved protection against damage and environmental influences and at the same time has an improved durability during the charging process.

These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.

The The invention is based essentially on the idea that the propellant charge protection container a protective cover, the at its intended use all propellant bodies encompassed on the circumference, and from one connected to the protective cover and in the region of the radial slots of the propellant charge body can be arranged Closure exists. In this case, the closure has a first flat Lock on, which has a central, radial slots the propellant body bridging Area that extends within the radial slots in the circumferential direction extends so that the propellant charge within the propellant charge container a have predefined position and above the first closure part one outwards open depression results. The first closure part is on one first side firmly attached to the protective cover and on his the first side opposite second side detachable connectable to a second closure part of the closure which in turn firmly attached to the protective cover adjacent to it. Besides that is attached to the first closure part at least one handle, by means of which the first closure part for opening the propellant charge protection container after pulled outside and the protective cover can be removed.

The cover may be made of plastic and preferably be cup-shaped, being made up of two over a hinge connection composed of interconnected plastic shells.

It but it is also possible as a protective cover to use an elastic fabric part.

The two preferably made of plastic closure parts can by means of an adhesive connector (adhesive, Velcro, etc.) detachable with each other be connected.

at a first embodiment The invention extends to the second closure part facing End of the first closure part in the radial outward direction, in this way that it acts as Ladebarriere and thus unintentional loading of with the propellant charge protection container provided mortar shell prevents a corresponding weapon. Preferably, it can be provided be that outward extending end of the first closure part designed as a handle is.

at a further embodiment the invention is attached to the first closure part handle in the Groove arranged above the first closure part.

Around a removal of the protective cover Even in the dark, the handle can be self-luminous formed (for example by means of a fluorescent material) be.

When the mortar shells are stored in a magazine in the region of the weapon (for example an anti-tank mortar), it has proven to be particularly advantageous if the second closure part has a hook-shaped end region which engages behind the propellant charge bodies in such a way that, when pulled on the gun Handle outward the Treibla training bodies of a mortar shell located on an ammunition rest rotate as long as the Leitwerkschaft until a desired removal position of the mortar shell or the propellant charge body is reached.

Further Details and advantages of the invention will become apparent from the following explained with reference to figures Embodiments. Show it:

1 a side view of a mortar shell in partial section;

2 a schematic representation of the cross section of a first embodiment of a propellant charge protection container for a mortar shell in a magazine holder, wherein the propellant charge protection container is closed;

3 a 2 corresponding view during the opening process of the propellant charge protection container;

4 a 2 corresponding view in which the propellant charge container is in its open position, in which the corresponding mortar shell can be removed from the magazine; and

5 a 2 corresponding view of a second embodiment of a propellant charge protection container according to the invention.

In 1 is with 1 a mortar shellable from a mortar mortar called, in a conventional manner from a headboard 2 with an active charge (not shown) and a Leitwerkschaft 3 with rear-mounted tail unit 4 consists.

Inside the Leitwerkschaft 3 an unillustrated lighter is arranged, which after its activation a Grundtreibladung 5 in the Leitwerkschaft 3 the grenade 1 ignites. The of the basic charge 5 generated hot combustion gases escape through holes 6 that are beyond the scope of the Leitwerkschaft 3 are arranged distributed to four there located propellant charge body 7 (often referred to as additional propellant charges) to light. In this case, the propellant charge bodies 7 in this embodiment, in each case a central opening 8th on and one in the central opening 8th passing radial slot 9 for pushing the propellant charge body 7 on the shaft 3 the grenade 1 ( 2 ).

According to the protection of the on the Leitwerkschaft 3 arranged, for example, horseshoe-shaped propellant charge body 7 against damage and environmental influences a propellant charge container 10 intended. This consists essentially of a protective cover 11 , z. B. plastic, in the intended use of the propellant charge container 10 all propellant bodies 7 peripherally includes, and at least one with the protective cover 11 connected and in the radial slots 9 the propellant charge body 7 attachable closure 12 ,

As 2 removed, is in the illustrated embodiment, the protective cover 11 cup-shaped and consists of two via a hinge connection 13 interconnected plastic shells 14 . 15 together.

The closure 12 has an existing example of plastic flat first closure part 16 on which one the radial slots 9 the propellant charge body 7 bridging mid-range 17 which is located inside the radial slots 9 extends in the circumferential direction, so that the propellant charge body 7 inside the propellant charge container 10 have a predefined position and above the first closure part 16 a recess open to the outside 18 results.

The first closure part 16 is on a first page 19 (For example, by plastic welding) firmly with the protective cover 11 connected and on its second side opposite the first page 20 detachable with a second example also made of plastic second closure part 21 of the lock 12 connected, which in turn firmly attached to the protective cover adjacent to him 11 is attached. It can for releasable connection of the two closure parts 16 and 21 an adhesive connector 22 (For example, a hook and loop fastener) may be provided.

At the first closure part 16 is also one in the depression 18 located handle 23 fastened, by means of which the first closure part 16 for opening the propellant charge container 10 pulled outward and the propellant charge container 10 can be removed (see also 3 and 4 ).

For this purpose, the second closure part 21 a hook-shaped end portion 24 on top of the propellant charge bodies 7 engages, such that when pulling on the handle 23 outward the propellant charge body 7 a mortar shell located on an ammunition pad 1 Together for so long to the Leitwerkschaft 3 Turn until a desired removal position of the mortar shell 1 or the propellant charge body 7 is reached.

Like also out 2 it is removable, he this stretches the second closure part 21 facing the end 25 of the first closure part 16 in the radial outward direction, and indeed so far that it acts as Ladebarriere and thus inadvertent loading of the with the propellant charge protection container 10 provided mortar shell 1 prevents a corresponding weapon.

Based on 2 to 4 Below is the removal of the mortar shell 1 from a magazine located in the corresponding tank 26 , which is indicated in the figures only by a dash, will be explained.

First, the entire grenade 1 on a located in front of the magazine ammunition storage (not shown) folded and then rotated by hand to a starting position, in which the in the recess 18 located handle 23 pointing upwards ( 2 ).

Then, with the right hand, the handle 23 grasped and with the left hand the mortar shell 1 secured against twisting. The propellant charge container 10 is then pulled down ( 3 ).

In this case, the propellant charge bodies 7 on the Leitwerkschaft 3 twisted so that the radial slots 9 of the propellant charges (uniformly) pointing downwards ( 4 ). In this situation can then the mortar shell 1 advantageously introduced into a corresponding gun barrel or - if desired - the propellant charge body 7 from the Leitwerkschaft 3 be removed.

For the entire operation of the above-described removal of the propellant charge protection container 10 requires a skilled loader less than 1 s. There is no mutual rotation of the propellant charge body 7 on the Leitwerkschaft 3 instead of what else could lead to charging and possibly also to shooting problems.

Of course, the invention is not limited to the embodiment described above. Thus, the protective cover of the propellant charge protection container, for example, consist of an elastic fabric part. A corresponding embodiment is in 5 shown. There are with 10 ' the propellant charge protection container and with 11 ' designates the protective cover.

At the in 5 illustrated embodiment is also provided that the outwardly extending end 25 ' of the first closure part 16 , which serves as Ladebarriere, at the same time as a handle 23 ' formed and with a self-luminous (for example, luminescent) coating 27 is provided.

It It is understood that in the context of the invention also uses multiple protective covers can be to protect the propellant. There are not necessarily several layers, but rather several on the Length of Propellant attached casings to understand.
