Description

The invention relates to a Werfereinrichtung comprising a tower with a pivotable about an axis holding means for receiving a cartridge, wherein locking means are provided for fixing the detachably attachable cartridge. Such facilities are out of the EP 0 247 712 A1 and from the US 2011/253025 A1 known.

Such a throwing device serves to launch a counter-missile with the aim of hitting and destroying a missile threatening the vehicle with this counter-missile at a sufficient distance from its own vehicle on which the throwing device is constructed, thus eliminating the threat. For this purpose, the throwing device comprises a tower on which a holding device for a cartridge is arranged. In the cartridge, the ammunition is used with the counter missile. If an approaching bullet is detected by means of a corresponding detection device, the cartridge is aligned within a very short time and the counter-projectile is fired. For this purpose, the tower is usually pivotable about a first axis or rotatable, while the cartridge is pivotable about a second axis or rotatable, wherein the two axes are perpendicular to each other. This allows alignment in azimuth and elevation. This alignment is extremely fast, the corresponding pivoting movements are performed in known Werfereinrichtungen within about one second or less, so that a quick shoot of the counter-missile is possible.

Device, the vehicle under fire, for example, by gunfire without the thrower device is to operate, may be given in the worst case, damage to the Werfereinrichtung and in particular the cartridge, so that a shoot of the counter-missile is no longer possible. However, the cartridge with the counter-missile is to be removed later, that is, it must be removed from the holding device, which of course involves a very high risk for the occupying soldier, since it can not be ruled out that it will detonate during this activity of the projectile is coming.

The invention is therefore based on the problem to provide a Werfereinrichtung that allows safe removal of the cartridge.

This problem is solved by the throwing device according to claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

In the throwing device according to the invention, the holding device is provided with a pyrotechnic release device, which can be controlled if necessary via a suitable control device and brought to the ignition. With ignition of the release device, the holding device, which fixes the cartridge firmly until then, opened, that is, the solid connection of the cartridge and holding device is released. Ideally, immediately after ignition of the release device, the released cartridge falls automatically to the ground. Should this not be so, then by a simple movement of the tower or the holding device to one of the pivot axes of the release of the released, no longer fixed cartridge done. Once the cartridge has fallen to the ground, the vehicle can safely move away. Even if an explosion occurs when it hits the ground, there is no person in the immediate vicinity, so the explosion is harmless.

In either case, to remove the loaded cartridge, it is not necessary for a soldier to manually operate on the holder to open it and remove the cartridge. The removal of the cartridge is therefore automatic and safe.

According to the invention, the locking means provided on the holding device first locking elements in the form of a locking hook and a locking pin and provided on the cartridge second locking elements in the form of a locking hook to be hooked pin and a clip closure with a hooked on the locking pin strap, the pyrotechnic release device when ignited in the area the connection of the locking hook with the Pin and / or the locking pin is arranged with the bracket. Cartridge locking takes place according to this embodiment of the invention with the aid of a clip closure. For this purpose, a locking hook and on the other side of the device opposite a locking pin is provided on the quasi-half-shell-shaped holding device. The cartridge in turn has a pin and located in the range of the other cartridge side strap closure with a swivel bracket, which hooks on a hanger hook on the locking pin of the holding device, on. To insert the cartridge, it is only necessary to use them in the half-shell-shaped device and hook the cartridge side pin on the locking hook of the holding device and then hook the hanger hook of the swing lock on halteeinrichtungsseitigen locking pin and pivot the bracket, so that a self-locking lock is given. This type of attachment of the cartridge is very simple and straightforward, so that reloading on site is very easy.

The pyrotechnic release device is now positioned so that when ignition one of the two connection points of the cartridge and holding device or both are solved. It is usually sufficient to solve only one of the connection points, since then the cartridge is at least loosely received in the holding device and can be easily dropped by a short pivoting movement of the holding device.

According to a preferred embodiment of the invention, the pyrotechnic release device acts on the locking bolt, such that it is moved out of its locking position. As described on the locking bolt hooked on the hook having the clip closure. The release device is now arranged such that the locking pin is moved by the explosion of the pyrotechnic release device from this locking position, which is most easily done by a corresponding linear movement along the bolt longitudinal axis. With sufficiently further movement, the locking pin separates from the bracket so that it is released and consequently the cartridge is no longer fixed. Only the pin located on the other side of the cartridge is still hooked on the locking hook of the holding device, but this is a simple rear grip, which no longer fixes the cartridge. It drops off respectively can be dropped by a simple short pivoting movement of the holding device.

The locking pin is preferably part of a bolt holder, in which the pyrotechnic release device is integrated. That is, a quasi self-assembly performing bolt mount is provided, which includes the locking pin and the release device. This makes it possible to carry out an exchange after ignition of a release device, and thus to restore the ability to function again in a simple manner.

The bolt holder is preferably used in a receiving bore on the holding device, wherein the receiving bore has a laterally open recess through which the locking pin is accessible to the bracket. Thus, a corresponding cylindrical receiving bore is provided on the holding device, which is readily accessible from the side, so that the bolt holder can be used in a simple manner. The locking pin passes through in the insertion a laterally open recess or is free on this, so that the bracket with its hook portion can hook on this easily.

The pyrotechnic release device is arranged to allow an axial movement of the locking pin in the axial extension of the locking bolt, so that the locking bolt is fired at ignition of the release device by the pressure building up in a arranged on the other side of the locking pin catching sleeve. If the pyrotechnic release device thus ignited, the locking pin is linearly shot from the recess, so that the rear bracket grip is released. To avoid that the bolt flies uncontrollably, a corresponding collecting sleeve is provided, in which the bolt is injected and which captures him. This collecting sleeve is arranged in the axial extension of the locking bolt, it is located a few inches away, that is, the actual, explosion-induced movement of the locking pin is relatively low.

The receiving sleeve tapers in diameter from the input side to the end, so that the bolt is securely fixed and is received in the collecting sleeve via an extremely strong clamp.

In this embodiment of the invention, the locking bolt is shot away from the pyrotechnic release device, that is, that the release device is arranged separately from the Ariel bolt. An alternative embodiment of the invention provides for this that the pyrotechnic release device in a hollow cylindrical Receiving portion of the locking bolt is received, which has one or more exhaust ports through which escapes when building up the release pressure based on what the locking pin is moved from its locked position. In this embodiment of the invention, the pyrotechnic release device, which is designed in all versions in the form of a sufficiently small primer, integrated in the locking pin. The pressure generated during ignition escapes via corresponding blow-off openings, which are preferably directed in the direction of a surrounding wall of the bolt holder. By then building up in the outer pressure of the locking pin is moved counter to the blow-out, with the primer is taken. In any case, the locking pin is moved axially from its locked position here, too.

In the embodiments described above, in each case the locking bolt has been moved out of its locking position. An inventive alternative to this provides that the pyrotechnic release device acts on the locking hook of the holding device, such that it is released from a fixation on the holding device. In this embodiment of the invention, therefore, the solution of the cartridge lock on the other side takes place by the locking hook is virtually blown off. After ignition of the release device, the cartridge is merely hooked on the hanger hook, if it has not already dropped by the ignition. This loose rear handle can be easily solved by a simple short pivoting movement of the holding device, so that the cartridge drops.

The locking hook is suitably screwed by a screw on the holding device, which acts on the release device. Alternatively, the release device can also be integrated in the screw, but in any case, when fixing the release device, the fixation of the locking hook is released via the screw. Immediately with the bursting of the screw fixation of the locking hook is free respectively falls off.

All embodiments described above provide for the cartridge fixing the clip closure, that is, that the holding device designed half-shell-shaped and the cartridge is inserted into this half-shell. An alternative to this provides that the holding device comprises a locking ring, in which the cartridge is axially insertable and in which the cartridge via locking elements, such as a bayonet lock, can be fixed. The locking ring is connected via a screw with the holding device, wherein the release device on the Screw acts or is integrated in the screw, such that when igniting the release device, the fixation is solved by the screw. In this embodiment of the invention, the cartridge is inserted axially into the locking ring and held, for example, by turning over a bayonet lock. This locking ring is screwed to the holding device via a screw. The pyrotechnic release device now acts on this screw, the screw is blown open when igniting the squib, so that the locking ring is no longer firmly connected to the holding device. He and with him the cartridge falls off with the ignition of the release device.

Fig. 1 shows a partial view of a throwing device 1 according to the invention, comprising a partially illustrated tower 2, which is rotatable about a rotation axis 3. On it a holding device 4 is provided for fixing a cartridge 5, which is rotatable about an axis of rotation 3 orthogonal axis of rotation 6. In this way, an alignment of the fixed cartridge in azimuth and elevation can take place.

Both on the holding device 4 and on the cartridge 5 corresponding locking means are provided which cooperate when the cartridge is inserted into the half-shell-shaped holding device 4.

The holding device 4 has two first locking elements 7 and 8, wherein the first locking element 7 in the form of a locking hook 9, which is formed over two hook portions 9a, 9b, which are spaced apart, is executed. The other first locking element 8 is realized in the form of a locking bolt 10, see Fig. 2 , is freely accessible via a laterally open recess 11 on the holding device 4. The locking pin is part of a bolt holder, which is inserted into a corresponding receiving bore on the holding device 4, which will be discussed below.

Second locking elements 12, 13 are provided on the cartridge 5, in the form of a pin or peg 14 hooked on the locking hook 9 in the case of the locking element 12 and in the form of a clip closure 15 in the case of the other second locking element 13. The clip closure 15 comprises a locking hook 16 having bracket 17, which is pivotally mounted on a pivot bracket 18 which is to be manually pivoted, and to a corresponding, the cartridge 5 receiving holder 19.

The FIGS. 3 to 5 show three different representations, which illustrate the process of attachment of the cartridge 5 to the holding device 4. For reasons of clarity, the cartridge 5 is only partially shown.

Fig. 3 shows the cartridge 5 a little further away to the holding device 4. The cartridge 5 is positioned so that the pin 14 to the locking hook 9 and the clip closure 13 facing the locking pin 10. The swivel bracket 18 is folded up, the bracket 17 is thus freely movable.

The cartridge 5 is now inserted in this position in the cup-shaped holding device 4. For this purpose, first the pin or pin 14 is hooked into the locking hook 9. Seen axially, the two hook sections 9a, 9b are slightly spaced apart, so that the pin 14 is hooked on two axially remote points, and thus subsequently also a tilt-proof holder is provided.

Then the bracket 17 with its hook 16, the locking bolt 10 hooked behind the locking pin 10. This situation is in Fig. 4 shown. The swivel bracket 18 is still pivoted upwards.

For fixing the cartridge 5, the swivel bracket 18 is now pivoted downwards. The holding device is fixed on the underside via the connection pin 14 - locking hooks 9. At the upper cartridge area, the bracket 17 is pulled by the pivoting of the swivel bar 18, so that the cartridge 5 is pulled firmly into the cup-shaped holding device 4. The swivel bracket 18 snaps over after overcoming the dead center and lies against the cartridge 5. From this position, he can not swing back automatically, a removal of the cartridge is possible only by manual vigorous pivoting. The either already loaded cartridge or still to be loaded cartridge is thus firmly fixed.

In order to be able to safely remove a cartridge damaged by bombardment or a striking other object, a pyrotechnic solvent is provided, with which it is possible to release the described, extremely strong cartridge fixing in the holding device 4. In the described embodiment according to Fig. 6 is the pyrotechnic release device 20 in a bolt holder 21, in which the locking pin 10 is added. The bolt holder 21 is a hollow cylindrical component which is inserted in a receiving bore 22 of the holding device 4. The bolt holder includes a hollow cylindrical housing 23, in which on the one hand the locking pin 10 is inserted, which is fixed via a fastening screw 24 which is screwed into an internally threaded portion 25 of the hollow cylindrical housing 23. The retaining screw 24 presses against a retaining foot 26 of the locking bolt 10, which is connected to the holding foot 26 via a predetermined breaking point 27.

The pyrotechnic release device comprises on the one hand a propellant charge 28, which is associated with a primer 29, which is fixed via a fastening screw 30, which is screwed to a second internally threaded portion 31 of the hollow cylindrical housing 23. The primer 29 is of course controlled by a corresponding control device.

The bolt holder 21 is inserted via an external thread in the female thread having a receiving bore 22 and counteracted on one side via a screw 32 which is penetrated by the locking pin 10. On the other side, a cover 50 is provided.

As can be seen, the locking pin 10 engages over the lateral recess 11. Opposite, the receiving bore 22 continues. The locking pin 10 is received in a screwed-in hollow screw 33 there, as Fig. 6 clearly shows. On the opposite side a collecting sleeve 34 is screwed, which has a blind bore 35 which tapers towards its end. This collecting sleeve 34 serves to catch the locking bolt 10 and decelerate.

If the cartridge 5 is to be dropped due to damage, then the primer 29 is triggered, it comes to detonation of the propellant charge 28. About the high pressure building up the locking bolt is axially and with respect to Fig. 6 pressed to the right, so it is shot across the recess 11. He is injected into the receiving sleeve 34 and remains stuck in the tapered blind bore 35. In any case, it is no longer in the region of the recess 11, so that the hook 16 of the bracket 17, the in Fig. 6 is indicated, is exposed, the locking pin 10 is therefore no longer engaged behind him. The local fixation of the cartridge is thus repealed pyrotechnic. The cartridge 5 can now fall off the holding device 4, optionally in conjunction with a short pivotal movement of the holding device 4, to release the pin 14 from its engagement with the locking hook 9.

Fig. 7 shows a further embodiment of a pyrotechnic release device 20, wherein the same reference numerals are used for the same components. There again, a locking pin 10 is provided, which passes through the recess 11 and is engaged behind by the hook 16 of the bracket 17. The pyrotechnic release device 20 in turn comprises a primer 29, a propellant charge 28 and a retaining screw 30. However, the release device 20 is here received in a hollow cylindrical receiving portion 36 of the locking pin 10. The receiving portion 36 has in the example shown on several exhaust openings 37. If the primer 29 is activated and detonation of the propellant charge 28 occurs, the pressure building up escapes from the interior of the hollow cylindrical receiving portion 36 via the exhaust openings 37 to the outside. The exhaust openings 37 open directly adjacent to a circumferential counter-pressure surface 38 of the housing 23 of the bolt holder 21, which in turn is screwed into the receiving bore 22 of the holding device 4. So there is a kind of recoil, the bolt 10 moves in Fig. 7 seen to the left along with the ignited pyrotechnic dissolving device. He is pulled out of the region of the recess 11, so that the hook 16 is released. The cartridge may fall off again. In this embodiment, therefore, the pyrotechnic release device 20 is integrated in the receiving bolt 10 and moves after ignition with this, while it is external to the receiving bolt 10 in the embodiment described above, which is shot away from her. However, both embodiments are equally functional and allow safe pyrotechnic release of entanglement.

The FIGS. 8 to 11 show a further embodiment, in which also on the holding device 4, the pyrotechnic solvent 20 (see Fig. 11 ) is integrated. This serves to release the locking hook 9. Die FIGS. 8 to 10 show three representations of how the locking hook 9 is mounted as a separate component on the holding device 4. With the interposition of a ring seal 39 of the locking hook 9, a one-piece component, attached to a corresponding mounting portion 40 of the holding device 4 and then screwed with a retaining screw 41. The mounting position is in Fig. 10 shown.

As Fig. 11 shows, the pyrotechnic release device is integrated in the retaining screw 41. The retaining screw 41 is hollow, in her the propellant charge 28 and the primer 29 is added. The screw head 42 is connected via a predetermined breaking point 43 in the form of a circumferential notch on the other screw body. comes it to detonation of the propellant charge 28, the screw head 42 ruptures at the predetermined breaking point 43 and is thrown off. The locking hook 9 is no longer fixed and falls off. Thus, the this-world fixation of the cartridge 5 is released, so that they can fall off.

The FIGS. 12 to 14 Finally, show a third embodiment of a holding device 4, which serves to receive two axially inserted cartridges 5 here. For this purpose, two locking rings 44 are arranged on the holding device 4. In the one locking ring 44, a cartridge 5 is already used as Fig. 12 shows. The cartridge 5 is pushed axially through the locking ring 44 and then fixed in it, for example by twisting in conjunction with a bayonet mount.

In order to enable a simple automatic ejection of the cartridge 5 in the event of damage, a pyrotechnic release device is again provided, which is realized via a pyrotechnic retaining screw 45. The retaining screw 45 is in a corresponding opening 46 of the holding device 4 from the back, see Fig. 13 , inserted or screwed in. It is, similarly to the screw 41, also hollow, in it the pyrotechnic release device 20 comprising a primer 29 and the propellant 28 is added. After insertion protrudes the retaining screw 45, see Fig. 14 , something from the holding device 4 forth. The locking ring 44 is placed so that an opening 47 provided on it engages around the retaining screw 45. Then, a retaining nut 48 is screwed onto the retaining screw 45 for fastening the locking ring 44, and then a cover cap 49 is attached.

If a cartridge is to be dropped in the event of damage, then the pyrotechnic release device 20 is actuated and detonation occurs. In this case, the retaining screw 45 tears in the region of the transition to the locking ring 44, so that it is released and together with the cartridge 5 drops.

Regardless of which configuration is actually provided, a secure solution of fixing the cartridge by igniting the pyrotechnic release device is always possible. This is of course connected via suitable line connections with control electronics. Of course, the respective cartridge when it is inserted into the holding device 4, connected to control the Verschusses of the recorded in the cartridge 5 projectile with control electronics.
