and more particularly relates to a device for clamping the pipe in the holder. With such an arrangement the lower end of the tube forms a third support point of the grenade launcher and is movable on one of the The bedding slab is stored on the ground.

When a grenade launcher is used, the bed slab sinks usually a bit into the ground with the first shot, which is why a missile shot is usually fired first and the weapon is only finally aimed after the bed plate has been set. When firing the The pipe must not yet be firmly connected to the carriage, as this would otherwise be due to the through The movement of the pipe caused by the bedding slab would fall over and / or injure the operating crew can. It is therefore necessary that the barrel when firing the missile to a certain extent opposite the pipe bracket of the mount can move.

Known pipe holders usually have two semi-cylindrical jaws which surround the pipe and which by means of a clamping screw can be tightened around the pipe. The two jaws are used to fire the missile bullet usually screwed together loosely so that the tube can move relative to it. After the agreement shot the jaws are then clamped tightly together in order to connect the tube to the mount.

This known clamping device for the tube holder of a grenade launcher mount has certain deficiencies .. Since the the clamping force exerted on the two jaws of the holder by means of the clamping screw cannot be precisely dosed, there is a risk of the screw being tightened too tightly or too loosely, which in both cases can lead to accidents can.

609837/0656

In addition, the plague pulling the tension screw is a tedious one and time-consuming work, and especially in cold weather it is made difficult by clammy fingers.

The invention is based on the object of a clamping device for the ear of a grenade launcher. by means of which the ear can be quickly and safely clamped, with a predetermined one for the detachment shot or adjustable small and for the subsequent effect ss. shooting a predetermined or adjustable large Clamping force is exerted.

This object is achieved according to the invention in that the pipe holder is one in one of the support legs carried support fork has attached bearing shell, which is hinged to it by means of a on one side of the tube, with a guide device on the opposite side of the bearing bracket cooperating bracket is lockable, which by means of one in two independent clamping positions with different Clamping force can be brought to the clamping device attached to the bearing shell.

The device according to the invention is designed so that the clamping device with a simple hand movement and without taking into account the clamping force to be exerted Can be brought into the two clamping positions, so that the risk of accidents due to incorrectly set clamping forces between the bracket and the barrel is reduced and the grenade launcher can be quickly brought into the firing position can. Overall, the invention facilitates the operation of the grenade launcher, so that he can in the shortest possible time can be set up and dismantled.

The following is an embodiment of the invention based on the drawing explained. Show it:

A grenade launcher mount shown in FIGS. 1 and 2 has two support legs 1, a bracket 2, which are spread outwards for a pipe 3 as well as a side ″ and a leveling device 4 or 5. ·

The support legs 1 form two support points for the grenade launcher and the sides movably mounted on a (not. Shown) bed plate lower end of the pipe 3 forms a third support point * · the support legs Λ have the lower end in each case a removable foot 6 with a vorzugsxfeise made of steel spur 7 'and are pivotably mounted on a heart plate 8 at the upper end. This has a pair of edges 9t which each form a stop for the support legs 1 in the spread position, so that the heart plate 8 always assumes a vorbe certain position relative to the support legs. the

609837/0656

Heart plate 8 also carries a device 10 for the lateral Tilting, as well as a device 11 for raising and lowering the pipe.

The bracket 2 carrying the tube 3 has a mount 2 mounted on a double-acting shock absorber arrangement 13 Bearing shell 12, which can be closed by means of a bracket 14, and a clamping device 15 for clamping the Tube 3 in the holder 2. The recoil damper assembly is attached to a support fork 16, which also has a A Mount for. the side straightening device 4 forms. The support fork 16 is about a transverse to the vertical axis of the The axis of the carriage can be swiveled. Fig. 1 shows the fork in the normal firing position, while in Fig. is folded up for better representation.

The side straightening device 4 also contains a threaded spindle which is rotatably mounted at its ends in the support fork 16 a nut 18 running back and forth between the ends. This sits on a protruding at right angles to the spindle Threaded nipple 19, by means of which the side straightening device 4 with the holder 2 on a height straightening housing 20 is attached. This in turn is fastened to the heart plate 8 by means of guides 21.

The bearing shell 12 of the pipe bracket 2 is attached to the Rückst oßdampferanordnung 13, which in turn is attached to the support fork 16 is attached. The recoil damper assembly comprises two mirror syrametrically and parallel to each other recoil dampers 13a, 13b attached to each arm 22 of the support fork, between which the bearing shell 12 is suspended from two sockets 23 (Fig. 3 »4). The bearing shell 12 has a substantially semi-cylindrical shape and can be closed by means of the also essentially semi-cylindrical bracket 14. This one is on one side of the

609837/0658

Bearing shell 12 articulated with a bolt 24. The bracket has a guide profile 26 at its free end on the other side of the bearing shell 12 cooperating guide profile 25 and an outwardly protruding bevel 27, on which the clamping device 15 engages.

The tensioning device has an inner and an outer tensioning handle 28 and 29, respectively, as well as two tensioning straps 30. Of the inner clamping handle is pivotably mounted on an eccentric bolt 31 and has on the with respect to the same opposite side a finger 32 for engagement in one formed by the nose 27 on the bracket 14- Recess. 33 * The outer cocking handle 29 has a U-shaped Cross-section and engages over the inner clamping handle 28, so that the two handles are one unit in the clamping position form so that the bracket can be released with a single movement and thus the pipe can be released. Of the Eccentric bolt 31 is adjustable on the outer clamping handle attached and is rotated by pivoting the same clockwise in Fig. 4 so that the inner clamping handle the bracket 14- tightened. The two clamping straps 30 are with a second eccentric bolt 34 on the bearing shell 12 hinged and carry the first at their free ends. Eccentric bolt 331, which in turn the clamping handles 28 and 29 wears. The second eccentric bolt 34 is used for adjustment a desired clamping force and is firmly connected to the clamping straps 30, so that when a Pivot the tensioning straps clockwise in Pig. 4th the distance between the clamping handles 28, 29 and the relevant side of the bearing shell 12 is shortened. The eccentric bolts 31 and 34 have a partially longitudinal direction grooved peripheral surface, which in conjunction with two Clamping screws 35 are used to 'secure them in the set position.

The two tension handles 28 and 29 enable the exercise

609837/0656

different clamping forces, i.e. a relatively easy clamping of the barrel for the deal shot and a firmer one Clamping the pipe for the fire of action.

To clamp the pipe in the holder, the bracket 14 and the clamping tabs 30 are opened so that the pipe can be placed in the bearing shell 12. The bracket 14 is then folded back over the tube so that the guide profiles 25 and 26 come into mutual engagement. The outer cocking handle 29 is approximately rectangular pivoted outwardly to the inner cocking handle 28, the finger 32 is brought into engagement with the recess 33 and the inner cocking handle 28 is pressed down onto the bracket 14. The second eccentric bolt is 3 ^ something twisted so that the. Distance between the clamping handles and the. relevant side of the bearing shell 12 shortened. This means that the pipe is easily clamped for the detachment shot. After the Abkommschuß the outer cocking handle 29 is depressed over the inner cocking handle 28 and thus the first eccentric bolt 31 twisted, whereby the two clamping handles 28 and 29 moved a little closer to the second eccentric bolt 34 and the bracket a exerts increased clamping force on the pipe. By appropriately adjusting the two eccentric bolts 31 and 3 ^ the optimal EinspaMkraft both for the Achieve agreement shot as well as for the effect fire. The clamping screws are used to set the clamping forces loosened, twisted the eccentric bolts to the necessary extent and then tightened the clamping screws 35 again.

The shock absorber assembly supporting the bracket described above has two mirror-symmetrically arranged parts 13a, 13b. A cross piece of the support fork 16 is penetrated near its ends by bores into which the two arms 22 are inserted parallel to one another are until they are with a collar 36 at a step 37 in. the

609837/0656

place the respective hole. The arms 22 are 'hollow and each secured by means of a hollow screw plug 38 in the relevant hole. On the right in 6, the hollow arm 22 includes a slidable guide bushing 39 and at the other end also an in Axially displaceable guide bushing 40 which sits with a collar 41 on an inner step 41 of arm 22 and so is held in it. Between the collar of the bushing 39 and the collar 42 of the guide bushing 40 is a Compression spring 43 held under tension. A lag screw rests with its head 45 on the outer face of the Guide bushing 39 and is threaded on the other End screwed into a nut 46. This has an external thread on which a movable arm 22 surrounding it Bushing 47 is screwed. The support bushing 23 of the holder 2 is pushed onto the bushing 47 and by means of a spacer sleeve 48 secured thereon immovable. The sleeve 47 has a length such that the distance between its right-hand end in Fig. 6 approximately equal to the distance between the head 45 of the tension screw 44 and the ' Bottom 49 of the hollow screw plug 38 and the distance between the nut 46 and the free end of the arm 22 is. This allows the socket 47 together with the bracket move a certain distance in both directions without damaging the various parts. The crosspiece of the support fork 16 has on the socket 47 facing side an impact damper 50 »which if necessary recoil forces not absorbed by the spring 43 attenuates.

When a grenade is fired, there is a recoil directed to the left in FIG. 6, through which the spring 43 is compressed via the bushing 47, the nut 46, the tension screw 44 and the guide bushing 39. The recoil can be so strong that the spring is essentially completely compressed. The recoil is followed by a

609837/0656

in Fig. 6 to the right directed rebound, where the guide bushing 39 rests on the screw plug 38 again and the spring 44 is compressed via the bush 47, the nut 46 and the guide bush 40. That rebound is usually relatively weak. If the rebound is excessively strong, the bushing 47 sits on the Impact absorber 50, which the remaining rebound forces records.

The tube holder according to the invention thus enables the grenade launcher tube to be clamped safely and quickly using two different clamping forces, xvelche are extremely precisely adjustable, so that the Risk of accidents due to the pipe being clamped too lightly or too tightly reduced to a minimum. the The extremely simple design of the holder also enables the grenade thrower to be set up and dismantled quickly he s, -

The invention is not restricted to the exemplary embodiment described, but in various ways modifiable. Thus, the bearing shell 12 can have an elastic, friction-enhancing coating on the inside and the two tension handles 28 and 29 can be mounted side by side or in any other desired arrangement which enables easy operation. .
