    The invention relates to a variable-length drawbar according to the preamble of claim 1, a truck trailer train with such a drawbar and a door for a box body for such a truck trailer drawbar.
    Box bodies with appropriate through-loading are known in different versions. Thus, DE 20 2009 016 356 U1 shows a towing hoist in which the passage-through possibility is produced by pulling the towing vehicle and the trailer equipped with an extendable drawbar apart for the purpose of loading and unloading and thereby producing the passage or passageway possibility is that a liftgate serves as a bridge between the towing vehicle and trailer. In order for the tail lift, which is adapted here to the cargo hold height of about 2.4 m, can serve as a crossover bridge, the towing vehicle and trailer must be pulled apart until the distance between the two vehicles corresponds to the tailgate length. 12/09/2011 15:55

    A disadvantage of this design is in particular that as a transfer device an elaborate tail lift is required.
    Furthermore, from DE 20 2009 010 516 Ul a trailer train is known, are approximated in the motor vehicle and trailer for transferring the total train of a driving mode in a loading mode to each other. The approach takes place here via a hydraulically adjustable drawbar, wherein the adjustment is made via a hydraulic motor. As front and rear gates on the box bodies here either roller doors or doors are provided.
    A disadvantage of this design is on the one hand, the complex and costly type of drawbar adjustment and the way the interaction of front and rear door: When using roller doors, as seen in the direction of travel front side of the bodies, the necessary stability and driving safety while driving , especially when braking, problematic. When using gullwing doors in particular opening in the direction of interior construction is possible only in the discharged state.
    A disadvantage of both solutions is also that a loading and unloading is not provided for set up Wechselkofferaufbauten.
    Also, the possibility of retrofitting the rigid drawbar trailer with a variable-length drawbar according to one of the solutions listed is possible only with uneconomical high effort.
    From DE 2452587 A1 a variable length towing bar is known, in which two are telescopically connected 12/09/2011 15:55
    No .: R494 P.007 / 042 12/09 2011 15:50 FAX +43 5522 73359 Patents Hefel @ 0008/0042 * * * * * * I · · · 4 · · · · · «« «« «« «« * · »· · · T 3 sliding tubes are used, which are connected in the extended state in a tension- and pressure-resistant manner. With a locking pin, the pipes can be fixed against each other. It is therefore a tow bar to replace a tow rope. A transition between two loaded - or to be loaded - vehicles is not provided.
    A similar device is shown in FR 1124718. However, this is an adjustable distance spacer to be used in a cable towing process.
    From DE 71 16 406 U a vehicle with arranged in the wall of the box-shaped structure door is known. The door consists of at least one upper and one lower part, wherein the lower part has on its underside guide pins, which cooperate with the guide rails being constructed. To open the door, the upper part of the door is pivoted hydraulically outwards about a rotation axis located on the upper side of the upper part. The guided in the guide rails guide bolts move forcibly upwards and cause a collapse of Tuerber and door base and thus the opening of the door.
    A disadvantage of this door is that the door elements can not be used for a truck trailer tow with variable length drawbar, as a pivoting of the door elements in the direction of the interior of the box body is not provided and the door always protrudes by a portion of its length on the structure. Furthermore, it is disadvantageous that a mechanical or manual solution to open the door is not 12/09/2011 15:56

    It is also known from DE 2735382 Al a controllable with a zipper tarpaulin for trucks. Although a cable pull solution is provided with which the slide of the zippers can be pulled up, at the same time open the zippers located on the sides of the rear tarpaulin and pulled up between the outer zippers cover is pulled up, but this cable solution is neither intended nor suitable to open a door consisting of fixed door elements.
    The present invention is therefore based on the object to provide an improved variable-length drawbar for a tow truck consisting of towing vehicle and trailer. Another object of the invention is to provide a truck trailer hoist consisting of a towing vehicle and a trailer, both of the towing vehicle and the trailer carrying a box body to be interconnected via a variable length drawbar. Furthermore, it is an object of the invention to provide a door for a box body of a variable-length drawbar interconnected truck trailer train.
    Motor vehicle and trailer should be able to be easily transferred from a drive into a charging mode; then loading and unloading, regardless of whether the superstructures are on the towing vehicle or the trailer chassis or whether in 12/09/2011 15:56

    Patents Hefel @ 10010/0042 presented condition with each other and / or connected to a loading ramp, can be performed.
    The object of the invention is achieved by a variable-length drawbar with the features of claim 1, a truck trailer with the features of claim 7 and a door for a box body with the features of claim. 9
    In particular, a Zentralachsanhänger can be equipped with such a collapsible drawbar. The use of, in particular hydraulic, drive components can be dispensed with. Furthermore, special components are largely dispensed with and resorted to known from the trailer technology standard components, such as an additional standard coupling pin, spring wings, compression springs and wear plates from the parts warehouse conventional automatic trailer hitches.
    The drawbar according to the invention allows in a simple manner the pushing together of towing vehicle and trailer. It is advantageous that the load is particularly secure against theft if the rearmost structure is docked to the loading dock of a logistics center consisting of a building and access to the rearmost sectional door is possible only from inside the logistics center. The cargo located in the box body block in addition to the internal locking the pivoting of the folding door.
    Insofar as the superstructures are stowable luggage stands on stanchions, it is possible for the suitcases to be erected after being pushed together by the towing vehicle or from 12/09/2011 15:57

    Separate trailer chassis and set down on unterzubauende or auszuschwenkenkende parking supports. The motor vehicle and the trailer chassis can then proceed in the direction of travel through the tunnels formed by parking supports and box bodies. The superstructures can be left individually, as far as the trailer's box body has been parked, or together, directly behind one another. It is advantageous that any length chains can be formed from successive structures. Even with such box body chains the rear, usually easy to open, sectional door is not accessible by the structure standing in front and thus secured. Access to the entire chain of superstructures is possible only through the rearmost structure.
    Preferably, the three tubes of the drawbar each have at least one located at the top of the tubes bore, preferably the tube assembly is associated with a movable, retracted from a retracted into the holes detent position in a drawbar release position sliding coupling pin. In this case, the bores are preferably arranged on a common central axis (M1), wherein the center axis of the bore of the middle tube (M2) lies in the driving mode on the central axis (M1) of the then aligned bores.
    The middle tube preferably has, in the region in front of the bore, a thickening which raises the coupling pin when the middle tube is pushed in, displacing the coupling pin drawn and locked from the bore region of the bores of the inner and middle tube into a position releasing its lock. The advantage is 12/09/2011 15:57

    7 it, if the thickening is designed as a replaceable Schleißpiatte.
    The invention preferably relates to a truck trailer train with a towing vehicle, which carries a box body, and in which at least the rear wall of the body can be opened, and a trailer, which also carries a box body and in which both the end wall and the Rear wall are openable and wherein the towing vehicle and the trailer are connected to each other via a variable-length drawbar. The construction of motor vehicle and / or trailer is preferably designed as a removable box body.
    Another embodiment of the invention relates to the design of a box body with a special folding door in the front and a known Sektio-naltor in the rear area. This combination allows the self-sufficient discharge of the parked structures from the rear side. First, the rear sector gate is opened. Subsequently, the loading space loaded, for example, with pallets is unloaded. Once the load compartment of the rear body is empty, the folding door in the front wall within the cargo space can still be pivoted up and then open the then accessible sectional door of the front body. In the same way, the cargo space of the front box body is then discharged to the rear, through the rear body, discharged.
    It is also advantageous that by the option of offsetting consecutive structures together, new logistics concepts are made possible. So it is possible, for example, two constructions in a row before 12/09/2011 15:58

In this case, the driver does not have to wait for the unloading of his first loaded train and is also independent of other warehouse personnel or their business hours. In addition, only one loading ramp is occupied by putting together a plurality of box bodies, or eliminates an intermediate transfer of a swap body by the driver with only one existing loading door.
    It is advantageous if, in the case of the door pivotally mounted in the front area below the box body roof, the at least two door elements are connected to one another via a hinge. The leadership of the door when pivoting takes place in an advantageous manner by laterally attached to the underside of the lower door element guide pins, which cooperate with a mounted on the side wall, vertical guide rail and forcibly control the up and down movement of the collapsible door elements.
    It is advantageous if the folding and upward pivoting of the door elements by pulling a rope, referred to below as pulling rope is effected, which is in the interior of the box body above the folding door with another rope, hereinafter called hoist rope, T-shaped and so that the tensile force is evenly distributed to the two branching strands of the hoist. 12/09/2011 15:58

    In this case, the branching strands are performed in an analogous manner above the folding door to the upper box body corners mounted baffles, preferably pulleys, and from there to the side of the folding door along down and around the laterally attached to the underside of the lower door element guide bolts around and back up to fixed attachment points located in the area of the upper corners of the folding door. The pulling of the pull rope causes a uniform pulling on the strands of the hoisting rope and thus lifting the guide pin and the whole folding door, with the door elements interconnected by a hinge, due to the forced guidance of the guide pin mounted on the lower door element in the on the side wall hang the box body, vertical guide rails, more and more folding and finally hang in the form of a compact package below the box body roof.
    It is advantageous if the towing rope from the point of attack on the hoist rope, about guide means, preferably guide rollers, below the box body ceiling is about 2 meters away from the folding door away and in this area has a locking device with one on the ceiling the counterweight attached to the body of the suitcase interacts and fixes the upwardly pivoted door elements after they have clicked in place, thus holding the folded-up door suspended beneath the boot lid.
    It is advantageous if the lower door element engages in fully pivoted position in a groove located in the bottom of the box body and so the closed 12/09/2011 15:59

    Patents Hefel @ 0015/0042 10 gives the door extra stability. The force exerted by a, for example, moving during the trip and pushing against the folding door charge can be compensated so better than a door that does not engage the box body floor groove.
    It is also advantageous if, the folding together of the door elements interconnected by a hinge blocked by the operation of a locking element and so the door can be locked in swung-out position.
    The invention will be explained in more detail with reference to an embodiment illustrative drawing.
    It should be noted that the special door construction according to claims 9-15 can also be regarded as an independent invention, since it is also used in trucks without length-adjustable drawbar, for example in truck trailer trains, in which the connection between the truck and trailer with a hinged Tail lift or an overhead flap is made.

    Figure 2 shows the variable length drawbar 6, which is associated with the trailer 4. But it is also possible to make the drawbar 6 as a replacement part, so that it can be used as needed in a trailer 4 instead of a non-extendable drawbar or installed.
    The drawbar 6 is a tubular structure, wherein it preferably han-delt in the tubes to square tubes, in which a total of three concentric tubes 7, 8, 9 are present. The middle tube 9 is relative to the outer tube 7, which is immovably connected to the inner tube 8, telescopically displaceable, but also fixable. The outer and inner tubes 7 and 8 form a rigidly interconnected assembly of the drawbar 6, in which a circumferential gap gap 6.1 is left open. In this distance gap 6.1, the middle tube 9 moves.
    The aforementioned assembly is connected to the chassis 37 of the trailer 4, in the illustrated case without a turntable. The middle tube 9 is provided at its free end with a 2ugöse 35, which is in a conventional trailer hitch of a trailer hitch, for example, the construction of the company Rockinger, used and there is releasably held.
    On the drawbar 6, a coupling device 6.2 is placed, which is connected to a coupling pin 13 which is displaceable in the vertical direction relative to the axial direction of the tubes 7-9. To move the coupling pin 13 is a locking lever 38. The three tubes 7, 8, 9 each have at their top one in 12/09/2011 16:00

In this locked state, the drawbar 6 is long and serves the normal transport and driving condition (see Figure 6).
    When the trailer has reached a discharge or parking position, the drawbar 6 should be shortened. With the help of the locking lever 38, the coupling pin 13 is first pulled from its locked position so high that the lock between the three tubes 7, 8 and 9 is released and the middle tube 9 between the tubes 7 and 8 is freely displaceable.
    Subsequently, the trailer tow of the driving mode (Figure 1) with the long drawbar 6 (Figure 2) in the loading mode (Figure 3) with the shortened drawbar (Figure 4) transferred.
    The towing vehicle 1 sets back and pushes the middle drawbar tube 9 in the gap between the outer and inner tubes 7 and 8, when the trailer 4 is stopped.
    FIG. 5 shows that, at the beginning of the displacement in the direction of the arrow PI, the middle drawbar tube 9 is displaced so far that the central axis M1 of the bores 10 and 11 no longer coincides with the central axis M2 of the bore 12.
    In the further course, the motor vehicle pushes the drawbar tube 9 back so far until a stop point 39.1 mounted on the middle drawbar tube 9 is attached to a stop which is formed on the inner and outer drawbar tube 7, 8

    Assembled assembly, stop point attacks 39.2 (Fig. 4).
    FIG. 3 shows that in the position thus defined, which represents the charging mode, there is only a minimal distance between motor vehicle 1 and trailer 4 and the loading and / or unloading process can be carried out.
    After completing the loading work, the towing vehicle 1 moves forward, thereby pulling the middle drawbar tube 9 in the direction P2 (FIG. 5).
    When retracting and extending the tube 9 from the position shown in Figure 5, the coupling pin 13 is only partially pulled out, namely so far that the tube 9 is movable. The coupling pin 13 is locked in this position in its vertical position and does not drag on the tube 9, which is moved in the direction of arrow P2 relative to the other two tubes 7 and 8. For the unlocking of the coupling pin a special function is provided. FIG. 5 shows that, in front of its bore 12, the middle tube 9 has a thickening 14 of the tube diameter. An inserted part of the tube 9 thus reduces the distance from the bore 12 to the lower end of the coupling pin 13. The coupling pin 13 comes just before the coincidence of the three holes 10, 11, 12 with the thickening 14 in contact and lifts the lock on the coupling pin , so that the coupling pin 13 can again pass through all three holes as soon as the central tube 9 is pulled out so far that the holes 10, 11, 12 are in alignment. 12/09/2011 16:01

    Due to the short lifting of the coupling pin 13, triggered by the thickening 14, which may preferably also be a wear plate, a hitherto the coupling pin 13 locked holding spring rocker of the coupling device releases 6.2. By the pressure of the compression spring, the coupling pin 13 connected to the spring rocker 6.3 closes and locks the pipes against each other. Triggerable coupling bolts are known per se, but not in connection with length-adjustable drawbars.
    The coupling pin 13 engages and creates a rigid connection between the motor vehicle and trailer chassis with a long drawbar. The entire train has now reached the driving mode and can then be driven forward together.
    The box bodies 2.1 and 2.2 can also be used as so-called "exchangeable cases". 2 'executed. Such exchangeable cases 2 'are usually connected via container closures, not shown, to the chassis of motor vehicle 1 or trailer 4. As far as a discontinuation of the exchangeable case 2 'of motor vehicle 1 or trailer chassis 4 is required, the container closures connecting the superstructures to the chassis are previously released and the superstructures placed on the superstructure supports 40 (Figure 1). The existing of the motor vehicle 1 and trailer chassis 31 train can then drive out under the Wechselkofferbauten 2 '.

    Subsequently, the motor vehicle 1 moves back further and pushes the middle drawbar tube 9 back so far until the attachment point 39.1 abuts the attachment point 39.2.
    Motor vehicle 1 and trailer chassis 37 are thus jointly driven so far under the bodies 2.1 and 2.2 until a position has been reached in which the container closures of the bodies 2.1 and 2.2 are located in the area of the motor vehicle 1 and trailer chassis 37 counterparts. The structures 2.1 and 2.2 can then be recorded in a known manner on towing vehicle 1 and trailer chassis 37 and connected to them.

    For this purpose, the rear-side sectional door 3 of the rear body 2.2 is opened, so that the rear bodywork can be driven or made. The discharge is usually done with this customary tools, such as smaller industrial trucks, which are suitable in terms of their size and weight for use in the interior of a box body 2 and in particular can lift and transport pallets.
    First, the rear box body 2.2 is completely discharged. Thereafter, a blocking element 34 of opposite the sectional door 3 folding door 5 is released. The latter consists of a lower door member 17 and a connected thereto via a hinge 21 upper Türele-element 16 which is mounted in the bearing points 18 and 19 in the front region of the box body 2 below the box body roof (Figure 8 and 9). By pulling on at least one of the located in the region of the hinge 21 handles 15, the folding door 5 is buckled slightly inward.

The lower door element 17 has guide pins 22 on both sides in the lower area, which are guided vertically in guide rails 24 connected to the side walls 23 of the box body 2.
    Furthermore, in the region of an upper corner of the folding door 5 (FIGS. 7-9), a hoisting rope 25 is fastened to an abutment point 26. This lifting cord 25 is initially guided downwards on the side of the folding door 5 within the guide rail 24 and then guided around the guide bolt 22 about a guide located in the foot region of the lower door element 17.

The traction cable 27 pulls the two strands of the hoisting rope 25, forcibly guided via centered left and right mounted deflection points 47, with the carriage 46 through the guide rail on the support member 30 and thereby lifts the guide pins 22 and 22 'at the bottom of the folding door. The further the pull cable 27 is pulled, the higher the guide pins 22 and 22 'are guided in the guide rail 24, wherein the upper and lower door member 16, 17 are folded against each other more and more inwardly.
    In the end position, the folding door 5 is completely folded and hangs upwardly pivoted door 33 in the interior of the box body below the box body roof 20. The pull cable 27 can be fixed by means of a latch 46 located on the carriage means 31 and the folding door 5 so in open Be held in position. The latching device 31, 32 may for example consist of a mounted on the carriage 46 locking pin 31.1, which is hooked after pivoting the folding door 5 in a provided for this locking pin 31.1 bore 32.1 in the mounted below the top 20 latching device 32. 12/09/2011 16:04

    Subsequently, the now accessible sectional door 3 of the box body 2 of the motor vehicle 1 is opened.
    Since the front and rear box body are directly behind each other, the passage between the two bodies is now possible and the front box body can be unloaded. A bridging of the minimum gap between the collapsed structures 2.1, 2.2 is not required in most cases, but can if necessary be made possible with the help of a support panel.
    This is done, for example, by a compression spring which braces the two parts of the latching means 31 and 32 together, briefly released manually for a short time and thus the withdrawal of the traction cable 27 is made possible. The weight of the two door elements 16, 17 causes their unfolding, wherein the trajectory of the guided in the guide rails 24, 24 'guide pin 22, 22' is forcibly controlled. Upon reaching the end position of the located on the underside of the lower door member 17 locking pin 42 presses against the cylinder 44 and thus against the located within the cylinder 44 compression spring 45. The weight on the cylinder dead weight of the folding door 5 presses the compression spring 45 together, so that Locking bolt 42 engages in the groove 43 located in the bottom of the box body.
    After closing of the locking element 34, the folding door 5 is thus a compact and robust unit which is also resistant to such loads as it 12/09/2011 16:05

    As an alternative to the swiveling of the folding door on the basis of a cable pull technique explained in the example, another solution, such as a rack and pinion technology with gears, can be provided for this purpose.
    The principle of the folding doors 5 is also applicable to the side walls of a box body 2, wherein the Zusammenklap-pen of upper and lower door element (16; 17) in this case is not in the direction of the interior of the box body 2, but to the outside. 12/09/2011 16:05
