  • the alarm device 100 comprises a sheet metal housing 102 which is to be attached to a rear wall of the frame element 32 of the vehicle frame 26 by means of fastening tabs 104, 106.
  • the two receiving chambers 108 are closed off from the housing interior 110 of the housing 102 by partition walls 122, 124.
  • the receiving chambers 108 have openings which face the tongue openings 40 and correspond in size to the tongue openings 40. This makes it possible for the tongue 38 to get into one of the receiving chambers 108 when the door locking device 30 is closed.
  • the receiving chamber 108 shown on the right-hand side has a sensor 112 which projects into the chamber 108.
  • the sensor 112 is an inductive safety sensor, which is designed to determine whether a metallic object - here the tongue 38 - is at a minimum distance from the sensor 112.
  • All components of the alarm device 100 can be accommodated in the housing 102, but it is of course also possible to accommodate only certain components.
  • the alarm device 100 can preferably be retrofitted and allows the alarm device 100 to be put into use after it has been mounted on the truck 10 only by connecting various further components.
  • the energy supply device 114 multi-relays 118, 120, an alarm horn 116 and a receiving unit are accommodated in the housing 102. How the individual components of the alarm device 100 are connected and function will be explained in more detail below Fig. 10 evident.
  • FIG. 8 shows a perspective interior view obliquely from the rear of the rear of a vehicle trailer with body, it is immediately apparent at which point the housing or the alarm device 100 with housing is arranged in the vehicle frame 26 or the frame element 32.
  • the alarm device 100 is shown, which is mounted behind the actual frame element 32. It is therefore only shown schematically at which point the alarm device is intended for assembly in relation to the doors 22, 24 and in particular to the door locking device 30.
  • FIGs 9a and 9b each show the same horizontal sectional view through the frame element 32 or the vehicle frame 26 with the alarm device 100 mounted therein.
  • the tongue 38 is in the right receiving chamber 108 when the state is closed ( Fig. 9a ) and during the opening process ( Fig. 9b ) is located.
  • the tongue 38 is at a minimum distance from the sensor 112. Due to the fact that the tongue is a metallic tongue 38 in this exemplary embodiment, the sensor 112 detects in the armed state of the alarm system 100 that the tongue 38 is positioned correctly and thus does not trigger a signal.
  • the tongue 38 is transferred from the closed position into an open position by means of the handle 35 and in particular the tongue 38 is moved away from the sensor 112. If the alarm device 100 is armed while the door locking device 30 is being opened, the sensor 112 triggers a signal in this case, since it is determined that the tongue 38 made of metal is no longer at the necessary minimum distance from the sensor 112. Of course, an alarm is also triggered when the alarm device 100 is removed, in that the sensor 112 is part of the device 100.
  • the Fig. 10 shows an exemplary embodiment of an alarm device 100 and in particular its individual components and their interconnection.
  • the energy supply device 114 here consists of a 3AH battery or a corresponding rechargeable accumulator.
  • a charge controller 138 which charges the charge via solar cells 156 Accumulator 114 performs.
  • a connection to the shown energy supply 154 from the towing vehicle can also be made possible, which is activated in particular when no energy is emitted via the solar cells 156.
  • the solar cells 156 can, for example, be placed on the roof of a vehicle trailer or a body of a truck.
  • the charge controller 138 hereby charges the accumulator 114 and supplies the various components of the alarm device 100 with energy.
  • a receiving device here part of the GPS tracking device 150, is connected to a switching device 155 wirelessly or via a cable.
  • the switching device 155 enables the alarm device 100 to be “armed” via a corresponding signal that is received by the receiving device 154.
  • the charge controller 138 is connected via multi-relays 118, 120 to the GPS tracking device 150 and / or a signal siren 116 as well as a side marker light 152 and the sensor 112.
  • This embodiment of an alarm device 100 according to the invention works as follows:
  • the alarm device is armed by the switching device 155 via the receiving device / GPS tracking device 150.
  • the receiving device does not necessarily have to be part of the GPS tracking device. It can also be provided as an independent component.
  • the sensor 112 is triggered and an alarm signal is given via the signal siren 116 and the side marker lights 152 start to flash.
  • the position of the alarm device 100 and thus, of course, of the trailer 10 is determined via the GPS tracker device 150 and what is not yet here It is shown in detail, sent via an output device to a receiving device with a warning message etc. that theft occurs.
  • the position data and a predetermined message can be transmitted, but it can also, for. B. the position of the vehicle trailer can be continuously passed on via the GPS tracker device. If no GPS signal is received, the last available position can be sent.
