The invention relates to a vehicle, in particular trailer vehicle, Karrette od. Like. For grenade launcher with a bottom plate un with a loading and unloading device, wherein the bottom plate and the weapon barrel connected by guided on the vehicle pulleys guided flexible tension members or traction ropes respectively an end position is moved as a transport position or as a firing position.

In use, known trailer vehicles for the purpose mentioned are uniaxial and have on their back a firmly attached to the vehicle frame support frame with conditions in which two Einhängorgane the bottom plate of a grenade launcher can be suspended. The loading of such in-situ grenade launcher on the trailer is done by this is raised on the front of the drawbar and thus tilted itself, the support frame is lowered. The suspension elements of the base plate are hung on the support frame, after which the drawbar is pulled down again under pivoting of the trailer around the trailer axle. Due to the leverage effect with the long tiller arm, the bottom plate of the grenade launcher can be lifted with the tube and pulled out of the ground. Finally, in the horizontal driving position, the bottom plate is pivoted beyond a vertical position and takes with the vehicle frame to the drawbar at an angle of less than 90 °. Disadvantage of this known trailer is that the inclusion or the loss of the grenade launcher must be done on balanced and level as possible. The backward driving with the trailer to the bottom plate of the grenade launcher must be done very accurately to hook the rigid frame in Verlastorgan the floor plate can. It is usually necessary to compensate for the inclination or drift deviations first by manually raising the grenade launcher. Also, the tilting of the trailer by lifting the drawbar may be difficult, but it is always necessary to charge the grenade launcher at all. The effort required to pull down the drawbar is high to eventually reach the towing vehicle cooperating transport position. In addition, the tippers of the carts usually have to be disassembled to tilt, and a larger operator's crew is required to cope alone with the weight balance when loading the grenade launcher when tipping the trailer back. If the Grantwerfer deeper embedded in the soil, it must first be laboriously dug and raised by hand, or must be 2ur Verlastung ever hoisted up with a crane car first out of its bedding.

From CH-PS 335 965 a mine thrower is known in which the training is made so that the bottom plate and the associated barrel guided by guided on the vehicle pulleys, flexible tension members or traction ropes each in an end position as transport position or as Firing position is moved. The flexible tension elements or Zugseile connected to a substantially extending in the vehicle longitudinal direction, hydraulic cylinder-piston unit and passed over a plurality of pulleys. For a correspondingly deep lowering of the bottom plate and the gun barrel, either the cylinder-piston unit must have a very large stroke or it must be provided additional means for changing the effective length of the tension members.

The invention has for its object to provide a vehicle of the type mentioned, which does not have the disadvantages described, and with ease of use and little complicated structure occurring during use errors in approaching the carcass and inclined and / or low position of the bottom plate is able to compensate. Furthermore, the loss should require as little operator crew, the Verlastungsvorgang should be done quickly and without complications, and it should be possible with the vehicle safer transport of the weapon even in difficult terrain.

To achieve this object, the invention essentially consists in that the loading and unloading device has a pivotally articulated on the vehicle balance lever body, at which connection or articulation points are provided for the guided over the pulleys tension elements, which connecting or Anlenkpunkte are arranged at the vertices of an imaginary triangle that extends towards the vehicle front side extending additional cable perpendicular to the imaginary triangle on the balance lever body, and that the tension elements are provided with connecting elements which releasably cooperate with connecting elements of the bottom plate. In this, a fast safe loading even in difficult terrain enabling vehicle, the balance lever body is a kind of balance beam, which is substantially horizontal or in the direction of the vehicle front side acting, forwardly extending Zugkraftaufbringungsorgan whose free balance, mobility and pivoting suspension forms suspension, and from this at three points to the rear also substantially horizontally extending three tension elements emanate vertically deflected to connect serve with the bottom plate of a grenade launcher, as a result of the free movement and pivoting of the balance lever body od each of the tension elements with its connecting element, eg hooks, Einhakösen od. Like

AT 401 310 Β the elements of the bottom plate can be brought and suspended there od. Like. The tension elements may be chains, straps, ropes or the like. Even with less accurate approach or tilt, a problem-free connection of the tension elements with the bottom plate is possible in the vehicle. If by means of the Zugkraftaufbringungsorgans the balance lever body is pulled toward the vehicle front side, as a result of its attachment, the tension elements are ultimately all stretched evenly, and it also takes place self-centering of the bottom plate while it is being wound. As a result of the vertical deflection of the tension elements, even a lower bedding of the floor slab does not hinder easy lifting and loading on the vehicle.

In order to effect more accurate guidance and smooth operation and increase the flexibility of the balance lever body, it is preferred that the compensation lever in the vehicle longitudinal direction a linearly movable longitudinal guide member, preferably with guide element, in particular guided on the frame of the vehicle car, slider, slide or the like., has, preferably connected to this articulated. In a simple design can be used as a longitudinal guide member z. B. an eyelet or the like. the balance lever body, which slides on a tensioned in the vehicle longitudinal direction guide cable may be provided.

Particularly effective tensile force transmission can be achieved if one of the connecting or articulation points of the tension elements is arranged on the longitudinal guide member of the compensating lever.

When the balance lever with the longitudinal guide member to a substantially by a connection or articulation of one of the tension elements and between the other two Verbindungsbzw. Anlenkpunkten the remaining tension elements extending axis is pivotal, precise guidance without annoying lateral deviation of all traction or train-stressed organs and yet a high level of balancing ability to connect the tension elements with the launcher in unprecedented driving, given in difficult terrain and schrägpositionieerter bottom plate.

If, as further preferred provided, the deflecting elements for the tension elements, preferably its frame or frame, hinged tilting frame are arranged, when the bottom plate is used with the launcher tube from its position to the carcass, the high tilting done with the rear tilt frame, whereby there increased ground clearance, shortening of the loaded vehicle and high position securing the weapon itself is achieved.

If, as provided according to a further advantageous embodiment, the tension elements by on the vehicle or the tilting frame arranged, with the releasably cooperating connection preferably suspension elements of the projectile weapon, in particular the bottom plate of a grenade launcher, and the tension elements cooperable receiving organs are performed, with which they are durable in the state of load in Lage, even with hochgeschwenktem tilting frame during transport slipping Base plate, which indeed has tension elements, Balancing lever body and Zugkraftaufbringungsorgan is under constant tensile load, not done. For example, these receiving organs may be about tubular Lagehalteösen.

In order to ensure a safe location of the gun barrel especially when loading and unloading the gun, especially a grenade launcher, it is particularly advantageous if the vehicle has a, preferably designed as a role, support for the gun barrel with releasable fixing organ. At this pipe support the tube can slide when mounting or depositing the bottom plate rolling.

It should be noted in particular that the distance around which the floor plate can be lifted with the just mentioned flexible pulling elements can be doubled in a simple manner in that the compensating lever body instead of direct connections with the tension elements has rollers, via which, for example anchored to the vehicle permanently connected holding elements, flexible traction elements are first performed running to the front and after deflection, as described above, extend backwards. With such a substantially inverse pulley construction, a Hubwegsvergrößerung can be achieved, but the tensile stress on the Zugkraftaufbringungsorgan is correspondingly larger. In special cases, a multi-roll pulley construction for the flexible elements may be provided instead of the individual roles. It should be mentioned that the Aufspulorgan for a trained in the form of a flexible tension element Zugbeanspruchungsorgan not necessarily on the wearer-bearing vehicle, eg on a cart, must be arranged, but it may also be on another vehicle, such as the towing vehicle itself.

For particularly heavy guns and to avoid a reduction in the lifting height, it is advantageous if the vehicle arranged the spring travel in the area of ​​the vehicle rear side

Vehicle wheels or axle (s) at Verlasten limiting, preferably on a deflection of the

Traction elements having tilting frame arranged, preferably pivotable with it, Federwegsbegrenzungsorgane, preferably bearing has.

AT 401 310 Β

If, as for rough terrain od. Like., A Verlast auxiliary device, which consists essentially in that in the region of the vehicle rear side, preferably on a deflecting member, preferably centrally, a deflecting saddle can be arranged over which, in particular for loading a deeply embedded projectile weapon with the, if necessary Guided by an auxiliary pulley, traction transfer member detachably connected Hilfszugeiement feasible and detachably connectable to the projectile weapon, Thus, the versatility of the vehicle according to the invention is significantly increased. By said leadership of the connected with its free end to the vehicle Zugkraftaufbringungsorganes on its own auxiliary role flaschenzugartige tensile force gain is achieved.

Based on the figure, the invention will be explained in more detail.

1 shows in full stroke a preferred type of uniaxial Karrette grenade launcher in the state B of the beginning of its Verlastung, and in broken line the grenade launcher tube in a position A after completed, vertical lifting, and the full state of loss T in side view. Fig. 2 shows the new Karrette in plan view, while Fig. 3 the same side view carabiner in two positions E, H, shows when a grenade launcher deeply buried in the ground is to be loaded.

In Figures 1 to 3 in side, top plan and another side view of an inventive trailer vehicle, namely a two with sprung on Achsschwingschenkel 2 common pneumatic tires having wheels 3 having Karrette 100 with Verlastungseinrichtung 200 with vehicle frame or frame and a fold-up drawbar support 22 shown. The drawbar 27 with eyelet 26 has a parallel drive 23 with, for example with not shown locking pin and link, cooperating Fixierungsausnehmungen 28, whereby it is parallel-höhenverstell- and fixed in position, and a hooks 30 and security chains 301 and further a handbrake lever 24. On the frame 1 in the longitudinal direction R1, R2 guided is movable as Guide member for a hinged to this with a leg, about Y-like balance lever body 11 trained carriage 10th To the hinged leg of the Y-frame of the balance lever body 11 is pivotable about an axis A1 in each case by angles substantially horizontally. By means of a drawbar near winch 21 with hand crank 20 can be mounted on a windable with this steel cable 37 which is hooked with Hakorgan 371 in the Einhängbolzen 181 on the balance lever body 11 approximately in the region of the fork of the Y-frame at 370 hinged drawbar 18 ,. Change horizontal position of the balance lever body 11 in the longitudinal direction of the vehicle 100. Of the balance lever body 11 go in each case in the direction R2 to the vehicle rear side of the end 140 of the carriage 11 hinged leg of the Y-frame and the other two free ends 130a, 130b, a total of three flexible tension members 13a, 13b and 14, said tension elements on Connecting elements 35,36 of the balance lever body 11 are detachably connected thereto. The tension elements 13a, 13b, 14 are deflected by means of arranged on a pivotally connected to the vehicle frame 1 tilting frame 6 deflection rollers 7 in the downward direction. They wear at their free ends fasteners, here Einhakösen 12, which, as shown, with three of six arranged substantially in a regular hexagon, over the surface of the bottom plate 40 of a grenade launcher 400 projecting hook 48 are releasably cooperatively connected. The hooks 48 have brackets 480 connected to the bottom plate 40, which are each again connected to the plate 40 via a connecting piece 482 to form a closed, handle-like, stable manipulating handle 485. The flexible tension elements 13a, 13b, 14 are cooperable with the mutually interacting suspension elements 48, 12 of bottom plate 40 and Zugelementenden, about tubular Lagehalteösen 8, with recess 81, by means of which position-stabilizing cooperation with the hooks 48 of the bottom plate 40 takes place when this is first pulled up in dash-dotted line position A against the tilting frame 6 and finally tilted with him in the likewise dash-dotted line indicated transport position T of FIG. 1. The bottom plate 40 of the grenade launcher 400 has a bearing body 401 with spherical recess 402, which cooperates with the correspondingly formed end piece 411 of the launcher 41 and a Höhenschwenkbegrenzungsorgan 49 with manipulation organ 498, which is 360 'within the bearing body 401 rotatable and positionable has , The tube 41 itself is placed at and for the loading on the roller-like pipe support 9 and can be fixed with a clamp 34 in the loaded state T. In order to prevent excessive stress on the suspension of the vehicle when pulling up the heavy base plate 40, the tilting frame 6 Federwegbegrenzungsorgane 32, which are also tilted down with him when tilting down and form an upper stop limit for the movement of the sprung axle 2. In the previously mentioned dash-dotted transport position T of FIG. 1, the tilting frame 6 is folded up with the him by means of the eyebolts 8 verschiebungssicher connected bottom plate 40, the launcher tube 41 is located substantially horizontally on the mitgekippten with the tilting frame 6 Rohrauflagerolle 9 and the ZugkraftbringungsSeil 37 is wound with the winch 21 and has only a small free length. With the carriage

AT 401 310 Β the balance lever body 11 is moved in a drawbar near position in the direction of R1, said lever body 11 with its drawbar 18 and its Einhängbolzen 181 on a hooking 171 of a support bracket 17, with the vehicle frame via a hinge 172 and with a Safety gear 39 is detachably connected, hung, so that the rope 37 and the winch 21 are relieved.

For loading is with tilted or demountable tilting frame 6 with the Karrette 100 rückling in the weft direction of the thrower 400 approximately centrally moved up to this, which is held according to the pipe pivot lock 49 of the bottom plate 40, the launcher pipe 41 in position. When about the wheel axle of the Karrette 100 has reached a position above the front outer edge of the bottom plate 40, the same can be turned off and secured with the hand brake 24. After releasing or Relaxing of the holding bracket 17 with the fixing wheel 39 depends on the Y-frame of the Ausgleichshebekörpers 11 Zugkraftaufbringungsseil 37 and after releasing the Kurbelelfixierung the winch 21 is released. The balance lever body 11 moves together with the carriage 10 in the direction R2 to the rear and thus occurs lowering of the tilting frame 6, wherein the Federwegbegrenzungsorgane 32 are effective to prevent unwanted springing. First, the centrally located and deflected at the drawbar 27 closer pulley 7 deflected rope 14 with its Einhaköse 12 pulled out of the eyelet 8, and under constant release of the pull cable 37 with the winch 21 to the respective nearest Einhakelement 48 with handle 485 of the pulled a total of six Einhakgriffe the bottom plate 40 and hooked to the hook. With further weakening of the winch 21, the two further outer cables 13a, 13b are hooked behind one another or simultaneously into a further two hooking grips 48 of the base plate 40 closest to the hooking lugs 12 of the cables 13a, 13b, so that the three ropes 13a, 13b, 14 are now hooked connected Einhakgriffe 48 with each other 120 ° occupy. Since the balance lever body 11 also around the connected to the carriage 10 leg of the Y-shaped frame, as shown in FIG. 2 can be pivoted in the directions R3, R4 in each case by relatively large angle a of about 40 °, even if the bottom plate 40 is heavily inclined, the suspension of the two further rear and outer traction cables 13a, 13b can be done easily. Thus, the attachment of a grenade launcher 400 on the trailer vehicle 100 is very quickly possible even on uneven and difficult terrain and very slanted embedded bottom plate 40. To raise the grenade launcher 400 when loading the winch 21 is operated by means of hand crank 20 for winding the pull rope, which are stretched over the compensation frame 11, the tension cables 13a, 13b, 14 with the same tensile force. Thereafter, the launcher tube is placed with bipod in the Rohrauflagerolle 9. By turning the Rohrschwenkbegrenzungsorganes 49 of the bottom plate 40 in the from Figs. 1 and 2 apparent position the launcher tube 41 is secured against tipping back in the direction R2 backwards. The tilting frame 6 itself prevented with its forward to each other at an angle guided struts 61 and a lateral tilting away of the tube 41 and secures its leadership to Auflagerolle. 9 The drawbar 27 in the case shown, causing a compression ratio of about 1: 6 held down and under winding with the winch 21 is pulled as a result of the balance lever body 11 each about the same tensile forces of the ropes 13a, 13b, 14, the grenade launcher plate 40 from their bedding, and in the sequence finally catch the Einhakösen 12 of the traction cables 13a, 13b, 14 together with the Einhakgriffe 48 of the bottom plate 40 in the eyelets 8 of the tilting frame 6, whereby position A of Figure 1 is reached. By further winding with the winch 21 then pivots the tilting frame 6 with the locked grenade launcher 400 in the transport position T, and it is then the bolt 181 of the drawbar 18 of the compensation frame 11 hooked into the hook 171 of the support bracket 17. When tightened fixing wheel 39 of the block 17, the end position of the loaded grenade launcher 400 is reached, the pull cable 37 is completely relieved and the crank 20 may, for example lashed or removed from the drive shaft of the winch. The tube 41 is secured with clamp 34. The transport of the Karrette 100 with the loaded grenade launcher 400 can be made to adapt to a towing vehicle after a corresponding height adjustment of parallel height adjustable Einhaköse 26 of the drawbar 27.

In Fig. 3 it is shown how in at a drawbar remote, notched position of the guide carriage 10 in the folded position of the frame-Ausgleichshebelkörpers 11 a loss can be initiated when a grenade launcher is embedded with its bottom plate 40 so deep that the full, approximately horizontal distance of the balance lever body 11 in the vehicle longitudinal direction R1 to a full pulling ultimately not sufficient in the Verlaststellung. The rear approaching with the Karrette 100 takes place, as already explained to Figures 1 and 2. The tilting frame 6 is lowered, the traction cables 13a, 13b and 14 and the balance lever body 11 are loose out of service. Now, as shown in the case, a Seilaufnahne 43 with separate guide roller 42 with a Hifsseil 44 and attachment accessories on the Karrette 100 are additionally attached. The pull cable 37 of the winch 21 is released from the drawbar leg 18 of the balance lever body 11, guided around the guide roller 42 of the auxiliary device and hung with its end on the support bracket 17 below. The arranged on a central pulley 7 Umlenk5

AT 401 310 saddle 431 guided auxiliary rope 44 is fixed in the bipod fixation or simply by wrapping the grenade launcher tube 41 at this, position E. When you operate the winch 21 2 tare cable 37 strained itself, so to speak, in the Fig. 3 dash-dotted lines after Rear tilted position H. Now, the resistance of the deep embedded grenade launcher 400 is overcome by the fact that the crew the Karrette 100 on the drawbar 27 and Eyelet 26 pulls down in the direction of the arrows R5, which with a leverage effect, in the case shown of about 1:12, the bottom plate 40 can be pulled out of its bedding. This lifting process is repeated until the Einhakhöhe necessary for Verlastung or sufficient Hochhievkraft is reached so that the grenade launcher, as described in FIGS. 1 and 2, can be charged. In addition, it should be noted that in an analogous manner, the bottom plate 40 can be pulled up in their Einhakgriffe 48. It may further be omitted the cable saddle 431 and the auxiliary cable 44 and directly the pull cable 37, are guided over the saddle 43 to the low-lying grenade launcher to its attachment, although not, as in the previously described process, the pulley-like power gain achieved by the guide roller 42 becomes. Furthermore, it is possible to pull the deeply embedded grenade launcher from the ground by reversing in conjunction with a towing vehicle. In this case, it is favorable when the traction cable 37 is guided over the towing vehicle by means of deflection rollers in order to relieve the drawbar. Even when transporting the Karrette in the most difficult terrain whose winch 21 can be used with traction cable 37 and pulleys, which can be gone up to the vertical abseiling. It can therefore be transported and loaded with the trailer according to the invention a grenade launcher in rough terrain. It is achieved with him short Verlastungszeit, which makes operation by only two men possible, at the same time the risk of injury is largely eliminated. The reference numerals of Figure 3 are otherwise analogous to FIGS. 1 and 2.
