Such launchers are light, stable and sufficiently cheap to manufacture that they can be used after the in the missile they contain can be thrown away. However, with the demand for more powerful projectiles occurs at the same time, the problem of keeping the shipments light and cheap enough.

In the German patent specification Mr. ..... (German patent application P 20 04 291.5) a weapon is described which consists of a front launcher section and a projectile, the housing of which is strong enough to withstand the pressure of the propellant charge contained in it when the propellant charge ^ is ignited. Means are provided on this weapon with which the front part of the housing can be releasably attached to the rear end of the launcher section. These means also form a gas-tight one. Seal. In this construction, the housing section serves as a disposable launcher section, while the front section can be reused with a similar projectile. However, this weapon has the disadvantageous property that it does not already contain the projectile, that is to say that the weapon and the projectile are separate.

The present invention has for its object to design a ^ missile launcher so that it combines the advantages of the launcher described in the above first patents with the advantages of that pitcher, which was recently described "The inventive thrower to the floor included, so that he is ready to fire immediately. The bullet housing will serve as a launcher section.

Based on the projectile launcher described above, there is the invention is that the housing section has a terminating part at its rear end and a projectile head and contains a propellant charge, that the launching device is connected to the propellant charge, that holding means are provided which tlen GenciioiSkopf i.iit dem Gehäuüeal.ujchni.it connect to a relative axial Vorüohlebuiu ·;

to prevent between the projectile head and the housing section, the holding means, however, correspondingly under the action of the propellant charge formed by the burning off high gas pressure are releasable so that the housing section has a wall that is strong enough to withstand the gas pressure to resist that sealing means are provided between the projectile head and the propellant charge, which seal of the space in which the propellant charge is located, both opposite the housing section and opposite the throwing section cause - whereby an escape of the compressed gas formed by the propellant charge is prevented to the front, and that sealing means are provided to seal the overlapping parts of the two sections against each other so that the compressed gas formed by burning off the propellant charge is not between the overlapping parts of the two sections can emerge.

The projectile, so the projectile head and the propellant charge are surrounded by a housing section, which the rear, in Diameter forms smaller launcher section. The projectile head is releasably attached to the housing section, namely at its final part.

Between the projectile head and the propellant charge, an intermediate wall part is preferably provided which is connected to has the projectile head. The connection can be released as soon as the projectile head has left the launcher. There is also a connection provided with the terminating part, which by the gas pressure developed during the burning of the propellant charge is solvable.

The launcher may contain a tubular part one end of which at the terminating end of the housing section of the launcher and the other end of which extends freely into a housing part on the front launcher section. The tubular member has an axially extending chamber in it, at the rear end of which is a primer for igniting an ignition cable is provided, polygamy can be distinguished by the

In the figures, the projectile is generally designated by the reference number 20. It has a tubular housing section 21, which is provided with a terminating part 22 at its rear end. The housing section 21 is telescopically inserted into a tubular launcher section 23, the terminating part 22 at the rear end of the Launcher section looks out when the launcher is in its shortened non-use form. The housing from: Section 21 is also provided with a handle 24 (see Figure 5), which makes it easier to pull out the thrower if this from his shortened non-use position into his extended use position transfers four to the should.

The launcher section 23 v / eist an elongated housing 25, which is provided on one side with a recess 26 which is used to receive a telescopic sight 27, which with the Section 23 is connected by a hinge connection 28. The hinge connection 28 makes it possible to use the telescopic sight swing out of its protected position of use into an exposed position of use.

In the top wall of the housing 25 there is a latching recess 29 which is protected by a lock 30. Behind the latching recess 29, in a side wall of the housing 25, there is an opening 31 which is protected by a lock 32 which covers a trigger shown as a rod 33. The trigger 33 has a central, transversely extending wall part 34 which is slidably mounted in a vertical channel 35 on the inside of the other side wall of the housing 25. The wall part 34 has a transverse slot 36. ^ Slot 37 in communication: with the cross slot 36 a is vertical.

As can best be seen from Figures 7 to 13, a rigid tubular member 38 which extends freely through the slot 36 is attached to the mounting portion 39, with which the handle 24 is attached to the nozzle end of the housing section3 21. The stiff tubular

Portion 38 has a partially threaded portion at its forward end provided bore 40, into which a threaded piece is screwed, to which one end of a leaf spring 42 is attached is (see Figure 10). At the other end of the leaf spring 42 A latch part 43 is attached, which is pressed against the upper side of the housing 25 by the leaf spring 42. That The latch part 43 engages in the locking recess 29 when the two Sections are pulled out into the position of use (see Figure 17) and forms a detachable connection between the two Absclinitten.

The threaded bore 40 in the tubular part 38 forms a chamber and has a longitudinal slot 44 siuf. A sear 45 which is slidably mounted in the chamber 4ü (and whose range of motion is limited by chamber 40) extends up through slot 44 and is through an ignition spring 46 pushed back. The sear 45 is held in position by a rod 47 which extends forwardly from the sear 45 through the threaded piece 41. The protruding from the slot 44 part of the Abzugstdllens 45 is shaped and dimensioned so that it through the slot 37 in the transversely extending wall portion 34 hindurc litre ten can. An ignition line 48, which is provided with a head 49, extends through the tubular part which rests against the wall of the chamber 40. The head 49 has a recess in which an ignition charge 50 is seated. That tubular portion 38 extends through nozzle 22 into the projectile, as will be explained in detail later. Of the Sear 45 includes a cavity 51, which against the Back of the trigger tunnel is open. The cavity 51 contains a central, in cross-section curtailed part 52 in which a firing pin 53 is slidably mounted. The firing pin 53 is provided with a head 54, which in the enlarged Part of the cavity 51 is seated. In this way, the firing pin 53 with respect to the sear 45 can have a specific perform limited movement.

When the rocket launcher has been extended so far that only a short further extension movement is required until the position of use is reached (see FIG. 7), then the sear 45 and the trigger part 35 come into contact with one another. During a further pull-out movement, the ignition spring 46 (see FIG. 8) is compressed. It can be seen from FIG. 10 that the sear 45 is in contact with the head 49 of the ignition line 48 when the launcher is not cocked. Although the ignition pin 53 is or can be in contact with the ignition charge 50, the possible range of motion of the ignition pin 53 is too short to cause unintentional ignition. When the trigger stud 45 is in the cocked position and the trigger 35 is actuated, the movement of the trigger stud under the influence of the ignition spring 46 causes the ignition pin 53 to strike the ignition charge 50. This triggers the ignition of the ignition charge, as will be explained later in connection with FIGS. 12 and 13.

Up to the point in time when the trigger 33 is actuated by moving the rod 34 transversely, the edge part 35 of the trigger 33 holds the sear 45 so that it cannot move under the influence of the ignition spring 46. When the trigger is actuated, the sear is free to move when the slot 37 of the trigger part 35 is aligned with the sear 45. However, a fuse is also provided, which is designated generally by the reference number 55 and can best be seen in FIGS. 7, 8 and 9. The fuse 55 includes a slide 56 through which the tubular member 38 slidably extends. The sliding part 56 is provided with a forwardly extending arm 37 which is guided through the slot and the slot part 37 (see Figure 3). The arm 57 secures the trigger 33 against movement until the safety 35 is still pulled backwards into a certain position. The Gluitteil 56 further includes two to \

rearwardly extending elastic arms 59. At the end of each of the two elastic arms 59 there is a finger grip 60. Each elastic arm 59 is furthermore provided with two grooves 61 and 62 which are spaced apart from one another in the longitudinal direction of the elastic arm. The rear end of the housing 25 has an inwardly directed shoulder 63 on each side. Each shoulder 63 engages the corresponding hat 61 when the fuse 55 is in its secured position (see Figure 7). When the arms 59 are pressed against one another, the shoulders 63 disengage from the corresponding hats 61. When the safety device 55 is then withdrawn so far that the stop 64 rests against one of the shoulders 6j5, and when the arms 59 are released again, the shoulders 63 snap into the hats 62. In this case: the lock 58 is also withdrawn from its operative position (see FIG. 8).

Looking at FIGS. 4 to 6, it can be seen that the projectile has a projectile head 65, a propellant charge 66, an intermediate wall 67 between the projectile head 65 and the propellant charge 66 and a holding part 68 in the form of a plug for the nozzle 22. The holding part carries an axially extending tubular part 69 which has a series of

The projectile head 65 has a shoulder 76 which on the front end of the housing section 21 rests, so that the projectile head 65 is blocked against backward movement. The projectile head 65 is connected to the intermediate wall 6-7, whereby the projectile head 65 is prevented from moving forward. The bulkhead is with the nozzle end of the section connected, as already explained above. The connection between the projectile head 65 and the intermediate wall 67 is from an axial projection 77 is formed on the front side of the intermediate wall 67. The projection 77 protrudes into a base 78 at the rear end of the projectile head 65. The projection 77 is provided with a transverse bore 79, which two rasp elements 80 contains, which are pushed apart by a spring 81. The "two locking elements are in alignment with one another Drilling. 82 pressed, which are provided in the rear end of the projectile head. That way is a connection formed between the projectile head 65 and the intermediate wall 67. ■

The projectile head 65 is provided with guide fins 83 which are hinged to the rear end of the projectile head 65 84 are connected. The guide fins 83 are in their inactive position by the sections 21 and 22 prior to launch held. But as soon as the projectile head 65 leave the launcher has, the guide fins 83 are pivoted out by springs 85. Each guide fin 83 has a cam portion 86, which presses a pressure piece 87 against the corresponding latching element 80. If the guide fins are swung out, so die. pressure pieces 87 press the corresponding latching elements 80 inward, whereby the partition 67 can now detach from the projectile head. A spring 88 held in the socket 78 is arranged compressed, then ensures that the intermediate wall 67 is snapped away from the projectile head 65.

on the quality of the seal between the overlapping parts of the tubular sections when they are pulled out are. If there were a leak, not only would the user be endangered, it would also the burning of the propellant can be influenced. The effectiveness of the projectile would be seriously affected because the necessary pressure would not develop in the housing when the propellant burned off. Also the exhaust fumes would Obgeschofiseiien backs pose a danger. Despite these dangers However, the sealing means between the pipe centers of the conveyor must not prevent the two sections from shifting to aciiwierif; f .. develop.

The thrower section 23 is the basis for this requirement an i.f.cli rearwardly extending sleeve 89 which has a series of annular channels 90 (see Figure 4). The rearmost channel 90 is provided with a seal 91 Provided in the form of a ring which is in sealing contact with the housing section 2ü.

head 65 is ejected but separated therefrom after the projectile head 65 flies free. The holding part 68 and the tube 69 are pushed rearward by the recoil gases.

The backward movement of the holding part 68 should be as small as possible. A preferred construction for the holding part is shown in FIG. Those parts which correspond to certain parts of the embodiment described above are identified by the same reference number, but with the addition of an "A". The holding member 68A is in the form of a cup and consisting of identical halves, which are butt edges by overlapping 92 interconnected ψ. The tubular part 69A extends through the bottom wall of the holding part 68A and is provided with flanges 93 extending in opposite directions, one of which is in communication with one half of the holding part 68A. Furthermore, the tubular part 69A is provided with a weakened area 94 on which warping forces can act during the burning of the propellant charge. This construction not only has the advantage that the tubular part 69A moves with the partition, but it also has the advantage that the holding part 68A with its two halves represents a minimal weight; the two halves are separated when the retainer 68A is removed.

As already stated above, the seal against gas leakage between the two launcher sections is very important. FIG. 15 shows an embodiment which can be used if a substantial difference in the diameter of the thrower sections is permissible. Those parts of this embodiment which correspond to certain parts in the previously described embodiment are denoted by the same reference number, but with a "B" added to the reference number. The front end of the housing section 21B is provided with an annular part 95 which has an annular channel open to the rear

having. A sealing ring is inserted in the annular channel 96. The shutter end of the launcher section 23B is with an annular part 9ö provided. The annular part 98 has a bearing portion 99 which is in contact with the housing portion 21B and an annular one on its front side Has flange 100. The ring-shaped one. Flange is shaped and dimensioned to be slidable in channel 96 immersed and with the sealing ring 97 forms a seal.

In practice the end part 22 is slotted at 101, so that the ignition lead 48 is not exposed outside the nozzle. A sprayed heap of plastic 102 forms an effective one Seal against ingress of liquid into the projectile. From Figure 14 it can be seen that for sealing the holding part 68A a similar seal 102A is provided.

From the above description it appears that the invention Throwers are a very effective weapon that is always ready to fire, which meets all the requirements for manufacture and use suffice.
