Definitions

  • the invention relates to a structure of a utility vehicle, in particular a truck, trailer or semi-trailer, with a rear wall frame and a rear wall door, the at least one rear wall door being held in the closed position in the rear wall frame.
  • the known commercial vehicles are known in different configurations, for example in the form of trucks, trailers or semi-trailers. Regardless of their design, the commercial vehicles are intended in particular for the transport of goods, that is to say the cargo to be transported, predominantly in public road traffic.
  • the known commercial vehicles have a chassis, a running gear connected to the chassis and a structure carried by the chassis, which provides a loading space for receiving the load to be transported.
  • tarpaulin structures are known which have at least one tarpaulin for closing at least one side and / or a roof of the tarpaulin structure. If a tarpaulin can be moved along a side wall, it is also known as curtainsiders.
  • a rear wall frame is provided at the rear, on which two rear wall doors are held and in which the rear wall doors are accommodated when the rear wall doors are in the closed position.
  • An end wall is provided opposite the rear wall frame. Corresponding end walls and rear walls can be provided in the same way for tarpaulin bodies and box bodies.
  • the side walls, the roof, the front wall, the floor and / or the rear wall doors can be constructed in the form of multi-layer panels, the outer structure-giving cover layers and a core layer made of foamed plastic in between.
  • the corresponding cover layers can, if necessary, each have multiple layers and serve to stiffen the panels, which is why the cover layers usually have at least one layer made of a metal and / or a fiber-reinforced plastic.
  • box bodies are closed, box bodies are used in particular for the transport of moisture-sensitive goods, i.e. so-called dry transport. Since the possibly provided core layer made of a foamed plastic can provide a high level of thermal insulation, corresponding box bodies are also particularly suitable for the transport of temperature-sensitive goods, for example for so-called refrigerated transport.
  • the rear wall is usually closed by two rear wall doors designed as wing doors, through which the cargo space can be loaded from behind.
  • the rear wall doors can be pivoted from a closed position into an open position.
  • the rear wall doors regularly have locking bars that extend above and below the rear wall doors and with the protruding sections on the upper and lower cross members the rear wall frame can be locked.
  • these locking bars can only protect against burglary to a limited extent, even if these locking bars are provided with a lock.
  • This lock can be opened with relatively little effort.
  • the assembly of the lock can be forgotten or at least opened by the driver of the utility vehicle.
  • Additional door locking systems have therefore been developed to prevent unauthorized opening of the commercial vehicle. These can be purely mechanical be designed or operated with an electric motor. Actuation with an electric motor has the advantage that this can be done via a control unit. The control unit can then ensure that the commercial vehicle can only be moved when the door locking system is locked, that signals are sent to a central monitoring unit during operation of the commercial vehicle that provide information about the status of the door locking system, that the unlocking of the door locking system is only possible in a specific one spatial area is released and / or that the driver of the utility vehicle cannot unlock the door locking system or at least cannot unlock it alone.
  • door locking systems have disadvantages.
  • the door locking systems can form cold bridges and / or reduce the insulating effect of the commercial vehicle over the long term.
  • Other door locking systems are complex to use or offer only very limited protection against being broken open.
  • the present invention is based on the object of designing and developing the structure of the type mentioned at the beginning and described in more detail in such a way that reliable protection against breaking in of the commercial vehicle can be ensured without any significant disadvantages compared to conventional structures without additional door locking systems have to.
  • a door lock housing is provided on the rear side of the rear wall door, each at least partially comprising an electric motor and at least one locking element which can be adjusted by the electric motor from a locking position to a release position and back the rear wall frame is provided with at least one latch receptacle for receiving the at least one latch element in the locking position.
  • a door lock housing is therefore provided that is arranged on the outside or the rear of the rear wall door. This eliminates, for example, an integration of the door lock housing in the rear wall door itself, the insulating effect of which would be reduced without further countermeasures. There is also no need to arrange the door lock housing in the loading space, which would lead to a reduced loading volume and impairment of loading. Furthermore, it is provided that an electric motor and at least one locking element are each received at least partially in the door lock housing. This not only simplifies the handling of the corresponding door locking system, but also enables additional security features to further improve the protection against breaking into the utility vehicle. For the actual locking of the rear wall door by the door locking system, at least one bolt holder is provided on the rear wall frame of the utility vehicle. The at least one latch receptacle is used to receive the at least one latch element in a form-fitting manner when it is in the locking position. With the locking element in the locking position, the rear wall door can only be broken open with considerable damage to the utility vehicle.
  • the structure is designed as a box body.
  • the advantages of the invention come into play to a particular degree, since the loading space of box bodies is already quite well protected against break-ins due to their basic structure.
  • it would also be conceivable to also close tarpaulin structures with additional devices in the area of the at least one tarpaulin so reliably that a door locking system on a rear door, including a tarpaulin structure, leads to significantly higher protection against a break-in into the cargo space of the commercial vehicle.
  • the at least one latch receptacle is provided on the back of the rear wall frame, it is easy to assemble and neither becomes the rear wall frame nor the base of the superstructure is weakened, unless additional compensatory measures are taken.
  • a particularly stable and robust locking of the rear wall door via the door locking system can be achieved if the at least one bolt receptacle is provided on a lower cross member of the rear wall frame.
  • the lower cross member is usually very solid and stable anyway, so that the cross member can absorb and dissipate high forces. It is also advisable if the lower cross member is assigned to the loading floor, in particular partially carrying the loading floor.
  • the cross member can take on several functions so that a synergy effect can be achieved.
  • corresponding crossbeams are designed to be particularly stable and resistant, so that additional reinforcement of the crossbeam can be omitted if necessary.
  • the door lock housing is provided on a lower edge of the rear wall door, this can counteract a possible break into the cargo space of the utility vehicle particularly well, since it would be particularly useful there to pry open the rear wall door.
  • Manipulation attempts on the door locking system can be prevented particularly effectively if the door locking housing protrudes over the lower edge of the rear wall door opposite the rear wall door.
  • the door lock housing therefore stands in the way of corresponding attempts at manipulation.
  • the at least one bolt receptacle can be at least partially received in the door lock housing in the closed position of the rear wall door. This can also make manipulation of the door locking system more difficult because the accessibility of the at least one bolt receptacle through the door locking housing is made more difficult or even prevented.
  • Tampering with the door locking system can alternatively or additionally also be avoided by joining the door locking housing to the rear wall door from the side of the rear wall door facing the cargo space.
  • a screw connection can be selected for the sake of simplicity.
  • the connection of the door lock housing and the rear wall door can consequently not be released from the outside, so that no special measures have to be taken to secure the connection against unauthorized release. So that the joint connection does not lead to a cold bridge in the area of the insulation and still reliably holds the door lock housing on the rear wall door, it can be advisable for the joint connection between the door lock housing and the rear wall door to have at least one joining means that extends at least essentially over the entire thickness of the door made of plastic or a fiber-reinforced plastic.
  • the joining means can be supported on the rear wall door over at least substantially the entire thickness of the rear wall door, so that the joining means can absorb large forces and transfer them to the rear wall door.
  • the at least one joining means is designed as a sleeve.
  • a screw connected to the door lock housing can be partially provided or partially received in the sleeve. This leads to a further stiffening of the connection between the door lock housing and the rear wall door. This is especially true when the screw is supported on the sleeve.
  • the screw extends in a direction perpendicular to the rear wall door over at least 20%, preferably 40%, in particular at least 60% of the thickness of the rear wall door from an inner layer of the rear wall door assigned to the cargo space is spaced apart.
  • this can be achieved if the screw has an outer layer of the rear wall door assigned to the outside of the rear wall door. In the respective way, a not inconsiderable or sufficient part of the thickness of the rear wall door is free of the screw, which can therefore only conduct heat to the loading space to a very limited extent.
  • the insulating effect can be increased even further if the at least one joining means is filled with a plastic, in particular a foamed plastic, at least in sections over its longitudinal extension perpendicular to the rear wall door.
  • a plastic in particular a foamed plastic
  • the foamed plastic has a lower specific thermal conductivity than the joining agent itself.
  • the corresponding use of the foamed plastic is particularly expedient if the joining agent is at least essentially between the screw head and the inner layer of the rear wall door with plastic, in particular a foamed plastic, is filled out.
  • the door locking housing can be made at least essentially from metal, preferably from steel, in particular from stainless steel.
  • the door lock housing can only be damaged or removed from the rear wall door with very high forces. Such forces are difficult to generate without special tools.
  • one rear wall door has the door locking system if the other rear wall door is provided in the closed position of the rear wall doors in such a way that it is prevented from opening by the closed other rear wall door by a positive fit. Then one rear wall door must first be opened before the other rear wall door can even be opened. It is thus sufficient to reliably lock one rear wall door using a corresponding door lock system with a door lock housing of the type mentioned. The two rear wall doors can then both do not open or only open with disproportionate effort. In other words, two rear wall doors can each be provided in the closed position in such a way that one rear wall door, which does not have a door lock housing, is positively held in the closed position by the other rear wall door, which has the door lock housing.
  • the electric motor can be connected to at least one line which, if necessary, can run from outside the rear wall door through the rear wall door to the electric motor.
  • the at least one line runs at least partially in a core layer of the rear wall door and / or runs in a core layer of a side wall.
  • the line can be connected to the electric motor via a plug connection in the connection area between the rear wall door and the door lock housing.
  • the plug connection it is advisable, if necessary, for the plug connection to be arranged at least essentially in a core position of the rear wall door or at least essentially in the door lock housing.
  • the rear door can be reliably secured against being broken open if the door lock housing is close to or adjacent to a locking rod that extends vertically over the entire height of the rear door and above and below it for locking with the upper cross member and the lower one Cross member of the rear wall frame is arranged.
  • this success can also be achieved in that the door lock housing is close to or adjacent to a handle, in particular below the handle, for locking and unlocking the locking rod with the upper cross member and the lower Cross member of the rear wall frame is arranged by rotating the locking rod.
  • This arrangement means that particularly high forces are required, for example, in order to pry open the rear wall door. Such forces cannot be easily applied without special tools.
  • FIG. 1 shows a utility vehicle 1 in the form of a semi-trailer with a body 2 in the form of a box body.
  • the utility vehicle 1 is pulled by a tractor 3.
  • the structure 2 of the commercial vehicle 1 has a fixed front wall 4, a fixed roof 5, fixed side walls 6 and fixed rear wall doors 7, 8 in the area of the rear wall 9.
  • the rear wall 9 of the structure 2 is formed by a circumferential rear wall frame 10 and two rear wall doors 7, 8 which close the opening of the rear wall frame 10 and which are attached to the rear wall frame 10 via hinges 11.
  • the rear wall doors 7, 8 can via the hinges 11 between an open position in which the loading space of the body 2 of the commercial vehicle 1 is accessible for loading and unloading via the rear wall frame 10, and a closed position in which the opening of the rear wall frame 10 is through the rear wall doors 7,8 is closed, can be swiveled back and forth.
  • the Side walls 6, the roof 5, the front wall 4 and / or the rear wall doors 7, 8 can be constructed in the form of multi-layer panels which comprise outer structural cover layers and a core layer made of foamed plastic in between.
  • the corresponding cover layers can, if necessary, each have multiple layers and serve to stiffen the panels, which is why the cover layers usually have at least one layer made of a metal and / or a fiber-reinforced plastic.
  • the rear doors 7,8 are shown in the closed position.
  • at least one locking rod 12 is provided on each of the rear wall doors 7, 8.
  • two locking rods 12 are assigned to each rear wall door 7, 8.
  • a different number of locking rods 12 can also be assigned to the rear wall doors 7, 8.
  • the locking rods 12 protrude above and below the respective rear wall door 7, 8 and can be positively connected to the corresponding sections of the locking rods 12 with the lower cross member 13 and the upper cross member 14 of the rear wall frame 10, which can be connected via lateral corner stanchions 15.
  • handles 16 are provided on the locking rods 12.
  • the rear wall doors 7, 8 are provided in such a way that the left rear wall door 7 must first be closed before the right rear wall door 8 can be closed.
  • the right rear wall door 8 in the closed position also holds the left rear wall door 7 in the closed position as a result of a form fit between the two rear wall doors 7, 8. Only when the right rear wall door 8 has been at least partially opened is the corresponding form fit canceled and the left rear wall door 7 can also be opened. For this reason, and to avoid unauthorized opening of the rear wall doors 7, 8, a door locking system 17 is provided on the right rear wall door 8.
  • the door locking system 17 is not so easy and / or cannot be opened by the same people as the locking rods 12, which can be secured against unauthorized opening with mechanical locks if necessary.
  • the locks can, however, be opened by anyone who is in possession of the corresponding key.
