The term “truck” denotes in particular a truck or commercial vehicle that does not fall below a permissible total weight of 3.5 t, in particular 7.5 t. In particular, the term "truck" includes vehicle trailers with bodies. The structure has, for example, one or more doors on a long side or at the rear, which are equipped with a door locking device of the construction described here.

On their rear loading and unloading facilities, trucks and commercial vehicles have rear doors that allow access to the vehicle's loading space. A door locking device is usually used to fix the rear doors in their closed position. The door locking device often consists of a handle element and a holding element, in which the handle element engages in a lockable manner. The handle element is usually attached to the rear door. Whereas the mounting element is attached to the frame of the truck or commercial vehicle. By engaging the handle element in the mounting element, the rear door can be locked and fixed in its closed position.

There has long been a need to better secure uncontrolled access to the inside of the truck.

Summary of the invention

According to the invention, the aforementioned technical problem is solved by an alarm device, which is preferably used to determine the unauthorized opening of a door locking device of a door of a truck a vehicle trailer is formed. The door locking device comprises a handle element which is movably attachable to the door and has a locking section having a tongue and a locking pawl for locking the door. The door locking device further includes a frame member of a vehicle frame having a bracket portion having a tongue opening for receiving the tongue and a pawl opening for receiving the locking pawl. The frame element preferably has a mounting section which is integrally formed in the frame element and is designed to receive the locking section. The alarm device comprises a receiving device which is designed to receive a signal from an activation device and to arm the alarm device. A sensor is designed to detect whether the tongue is in its locked position when the alarm device is armed. An alarm signal output device is connected to the sensor and, if the sensor does not detect a locking position of the tongue when the alarm device is in the armed state, outputs an alarm signal. An energy supply device is connected to the receiving device, the sensor and the alarm output device in order to supply these components with energy.

Advantageous embodiments of an alarm device according to the invention can have one or more of the following features

The alarm device is preferably activated by a switch located on the truck or via remote control (switching on and off). Arming can also be carried out using other means of communication such as a cell phone, computer-controlled central unit, tablet or a telematics system. In particular, in these cases it is possible to provide the shaft circuit in such a way that it can only be canceled if the transmitter receives a signal that the arming signal that a predetermined one Target position was reached. However, arming can only take place from a certain position. The arming can then be switched off remotely, for example, or the driver can only then switch off the alarm device.

In an exemplary embodiment of the present invention, the energy supply device operates on a voltage supply of 3 V to 24 V, in particular 12V. A charge controller is preferably provided, which supplies the various electrical components of the alarm device with energy. In particular, such a charge controller is designed to ensure that an accumulator is charged by various energy sources such as that of the towing vehicle and / or solar cells on the charging vehicle.

In an exemplary embodiment of the present invention, the sensor is an inductive safety sensor, which is designed to detect the locking position of a metallic tongue without contact. An ACC alarm can be triggered via door contact and opening the doors. A door lock can also be reported. Preferably, an ACC alarm can be triggered via a switched voltage - as soon as the ignition is switched on, a message is sent via SMS about "switching on the ignition". An ACC alarm system is, for example, a system such as that offered by Alarm IT Factory GmbH, Germany.

In a further exemplary embodiment of the present invention, the alarm signal output device comprises a sound output device and / or light signal output device. In the event of an alarm, i.e. when the alarm system is armed, the door lock is opened, causing the tongue to move away from the sensor, an independent activation of a siren (Hupton) and / or of existing vehicle lights, such as side marker lights that flash kick off. For example, a relay and / or a diode is connected between the alarm device and the lights for this purpose.

In an exemplary embodiment of the present invention, the alarm device further comprises a transmission device connected to the energy supply device and the alarm signal output device, which is designed to wirelessly send a signal or a message to one or more receivers. An alarm signal can e.g. cause an ignition device and / or a fuel delivery pump, etc. to be switched off. A message can contain any desired information, in particular the current or most recently determined position, time, etc. of the alarm.

In an exemplary embodiment of the present invention, the alarm device comprises a position determining device which is connected to the energy supply device and the alarm signal output device and is designed to determine the actual position of the alarm device. For example, a GSM / GPRS mobile radio device with SMS transmission (850/900/1800 / 1900MHz Quad Band) can be installed, which one or more events such as sends a warning or intrusion to one or more programmable phone numbers via SMS or Internet service provider such as Whatsapp. Thus, instead of an SMS, an alarm device according to the invention can also be switched to the Internet protocol, the messages and positions can then be transmitted to a server. In fact, any known telematics or telemetry systems can be used.

In an exemplary embodiment of the present invention, the alarm device further comprises a movement sensor connected to the energy supply device and the alarm signal output device, which is designed to detect a movement of the alarm device.

In an exemplary embodiment of the present invention, at least the receiving device, the sensor and the energy supply device are accommodated in a common housing.

In an exemplary embodiment of the present invention, the alarm signal output device and / or the transmission device and / or the position determination device and / or the movement sensor are additionally accommodated in the housing.
In an exemplary embodiment of the present invention, the housing is designed to be fastened on the inside of the frame element of the vehicle frame.

There is preferably also a SIM card slot and a common prepaid SIM card can be inserted.

A "listening function" can also be provided from a distance. Noises and conversations can then e.g. be heard over the phone.

An SMS notification can also be provided if the energy supply device is disconnected or if its power is deteriorating or has been used up.

In addition, a safe lock activation function such as switching on or off, opening or closing can be provided not only via GPS, cell phone but also via the ignition lock on the towing vehicle (truck) or via a key on the trailer.

Furthermore, a continuous auto tracking function can be activated with different time and distance intervals.

It is also possible to integrate an SOS function into the alarm device - a programmed phone number is notified via SMS via a button.

It is also possible to provide a geo-fence function. As soon as the alarm device leaves a programmable area, this is reported via SMS along with Google Maps and possibly displayed.

Furthermore, it is also advantageous if a movement alarm is provided. As soon as the truck moves, a report is made immediately

It is also possible to provide a speed warning function. If a speed is exceeded or undershot, the vehicle is parked unscheduled or the speed is significantly reduced, this can be reported.

In a further exemplary embodiment of the present invention, the housing is designed with a dividing wall which separates the interior of the housing from a receiving chamber for the tongue. The sensor protrudes through an opening in the partition into the receiving chamber. By means of this configuration, access to the wiring of the sensor is at least made more difficult and thus the risk of manipulation on the sensor is also reduced.

Manipulation is also made more difficult by the fact that when a supply line to the sensor is disconnected, the alarm device emits an alarm signal

According to a further aspect of the present invention, the aforementioned technical problem is solved by a truck that comprises a vehicle frame, a door that is at least partially movably attached to the vehicle frame, and a door locking device. The door locking device comprises a handle element which is movably attached to the door and has a locking section having a tongue and a locking pawl for locking the door. A frame member of a vehicle frame has a bracket portion which has a tongue opening for receiving the tongue and a latch opening for receiving the Has locking pawl, an alarm device of the embodiment disclosed here is present on the truck.

In an exemplary embodiment, the sensor is arranged on the inside of the frame element and on the side of the tongue opening, so that access to the sensor is prevented at least in the locking position of the tongue. In particular in connection with the partition, this at least makes manipulation of the sensor more difficult.

In the context of this disclosure, the term “vehicle frame” denotes a longitudinal or cross member of the truck as well as a frame of a truck body, for example a roof spar, side structures or stanchions of the truck.

In a particularly inexpensive embodiment of the door locking device according to the invention, the holding section is formed by at least one opening which is formed in the frame element of the vehicle frame.

In a further embodiment of the door locking device according to the invention, the mounting section is integrally formed in the frame element such that the mounting section is flush with the frame element on a side of the frame element facing the handle element. The flat design prevents damage to the mounting section and thus to the door locking device when the truck is reset with the rear doors open. In addition, this configuration represents a weight and component saving and enables easier and cheaper maintenance of the door locking device.

In a further embodiment of the door locking device according to the invention, the handle element and the frame element have a hole through which a customs cord can be passed, so that unwanted access to the cargo space of the truck is prevented.

In a further embodiment of the door locking device according to the invention, the handle element can have a locking pawl for locking the handle element in the mounting section, the locking pawl being movable between a locking position and a release position via an actuating element of the handle element. In this embodiment, the grip element can furthermore have a bore running underneath the actuating element, through which a customs cord is guided such that actuation of the actuating element is not possible. The hole, together with the customs cord, prevents unwanted access to the cargo area of the truck.

Detailed description

In the Fig. 1 is in the form of a truck trailer 10 an example of a load or. Commercial vehicle shown. As mentioned at the beginning, in the context of this disclosure, the term “truck” is understood to mean a self-propelled or externally propelled truck for the transport of cargo, which preferably does not fall below a permissible total weight of 3.5 t, in particular 7.5 t. The truck may be a truck trailer 10 as shown here, a semi-trailer for a semi-trailer or any other type of truck trailer, such as a drawbar trailer or the like. The truck can also be a tractor, such as a tractor unit or another tractor.

The Indian Fig. 1 The truck trailer 10 shown has a truck rear area 20 and two doors 22, 24 arranged on the truck rear area. The doors 22, 24 are movably attached to the vehicle frame 26 of the truck trailer 10. As mentioned, in the context of this disclosure, the term “vehicle frame 26” is understood to mean both the transverse or longitudinal member of the truck trailer 10 and a frame of a truck trailer body. To clarify this, for example, in the Fig. 1 the stanchions attached to the side of the cross member 26 of the truck trailer 10, which are used to fasten the doors 22, 24, are also designated by the reference number 26. Further parts of the vehicle frame 26, which are not shown in detail here, are, for example, a roof rail or side structures of the truck trailer 10. Naturally, doors with a door lock disclosed here are to be provided on the front or rear of a structure.

Like in the Fig. 1 shown, the doors 22, 24 are shown as vertically pivotable doors. Of course, it is also possible for the doors 22, 24 to be pivoted horizontally or otherwise movable on the vehicle frame 26. For example, the doors 22, 24 can be movably attached to a side structure, a roof rail, stanchions or other parts of the vehicle frame 26. In other embodiments, the truck trailer 10 can of course also have more or fewer than two doors 22, 24. For example, it is possible for a roller door to be attached to the roof rail of the truck trailer 10 so that it can be rolled up.

Like in the Fig. 1 is shown, the truck rear area 20 further includes a door locking device 30, which is designed to lock the doors 22, 24 in their closed form. As will be described later, the door locking device 30 has a handle element 35 which is fastened to the door 22, 24 and has a holding section (cf. Fig. 4 ) one Frame element 32 of the vehicle frame 26 interacts in such a way that the door 22, 24 can be locked or locked in its closed form.

In the context of this disclosure, the term “frame element” designates a part of the vehicle frame 26 of the truck trailer 10. The frame element 32 is thus not a separate component of the vehicle frame 26, but rather a section of the vehicle frame 26. Thus, a frame element 32 of the vehicle frame 26 of the cross member 26 his. A frame element 32 of the vehicle frame 26 can also be the roof rail of the truck trailer 10 already mentioned.

The door locking device 30 can furthermore have a plurality of grip elements 35, each of which cooperates with a holding section correspondingly formed in the frame element 32. As an example, the door locking device 30 has two handle elements 35 per door 22, 24. Furthermore, the handle elements 35 are arranged below the door 22, 24 as an example. The handle elements 35 can of course also be arranged above or to the side of the door 22, 24. It is also possible for more or fewer than two handle elements 35 per door 22, 24 to be arranged on the truck rear area 20.

In the Fig. 2 10 is a detailed view of the truck rear area 20 of FIG Fig. 1 shown with an exemplary illustrated door locking device 30. For ease of understanding, the door 22 is only indicated schematically in the form of a door frame 34. The Fig. 2 also shows the frame element 32 described in the introduction, which is part of the vehicle frame 26 of the truck trailer 10.

The door locking device 30 consists of the handle element 35, which is connected to the door 22, 24. In the embodiments shown, the handle element 35 is rotatably connected to the door 22, 24 via a pivot pin 36. The grip element 35 interacts with the frame element 32 such that at an engagement of the grip element 35 in the frame element 32, the door 22, 24 is fixed in its closed position, as described in more detail below in connection with FIG Fig. 3 is explained.

The Fig. 3 shows a rear view of the Fig. 2 . As can be clearly seen, this is shown in a rear view in the Fig. 3 shown grip element 35 has a tongue 38 and a locking pawl 42. The tongue 38 engages in a tongue opening 40 formed in the frame element 32 and the locking pawl 42 engages in a latch opening 44 formed in the frame element 32.

The specialist is in synopsis of Fig. 2 with the Fig. 3 recognize that a handle element 35 connected to the pivot 36 below the doors 22, 24 can be used to actuate a tongue (not shown) formed on the top of the pivot 36 in such a way that it engages in a tongue opening (for example on the roof rail) ( not shown) engages lockable. In other words, it is possible that the grip element 35 attached below the doors 22, 24 not only locks the tongue 38 in the tongue opening 40, but also, via the pivot pin 36, a second tongue attached to the pivot pin in a second tongue opening above the doors 22, 24 locked. The pivot pin 36 thus enables the doors 22, 24 to be locked below and above the doors 22, 24.

The exact design of the tongue 38 and the locking pawl 40 is in connection with the Fig. 5 and 6 described in more detail. In the following, we will first use the Fig. 4 the configuration of the tongue opening 40 and the pawl opening 44 is explained.

In the Fig. 4 the frame element 32 is shown without the grip element 35. As can be seen, the tongue opening 40 and the pawl opening 44 form an integral part of the frame element 32 Bracket section 45. For example, bracket section 45 was made by a separation process applied to frame member 32 such as a chip removing process such as milling, a non-cutting process such as laser cutting or punching, or other suitable processes. The bracket portion 45 is in the embodiment of FIG Fig. 4 through openings 40, 44 formed integrally in the frame member 32. By integrally forming the mounting section 45 in the frame element 32, the door locking brackets previously attached to the cross member 26 or roof rail of the truck trailer 10 can be replaced.

Furthermore, in some embodiments, the holding section 45 can be integrally formed in the frame element 32 in such a way that the holding section 45 is flush with the frame element 32 on a side of the frame element 32 facing the grip element 35. In other words, the holding section 45 can be designed integrally in the frame element 32 such that the holding section 45 does not protrude on a side of the frame element 32 facing the grip element 35. In other words, the mounting section 45 on the side of the grip element 35 forms a flat closure with the frame element 32. The flat closure can ensure that when the truck trailer 10 is reset with the doors 22, 24 open, no damage to the mounting section 45 is caused, for example, by Bumped against a loading ramp. In that the mounting section 45 is set back from the side facing the grip element 35, accidental damage to the mounting section 45 during loading and unloading of the truck trailer 10 is avoided. The door locking brackets known from the prior art, however, are screwed to the vehicle frame and do not form a flat end, so that one Resetting the truck slightly damaged the bracket elements and thus the door locking device can be made unusable.

Like in the Fig. 4 further shown, the tongue opening 40 and the pawl opening 44 in the holding section 45 of the frame element 32 are spaced apart from one another in such a way that the tongue 38 and the locking pawl 42 can engage in the openings 40, 44. In other words, a distance 46 between the tongue opening 40 and the pawl opening 44 is in the Fig. 4 is indicated by dashed lines, adapted to a distance between the tongue 38 and the locking pawl 42. The tongue opening 40 also has a substantially rectangular shape with rounded corners. The rectangular shape of the tongue opening 40 is such that a height 47 of a side 48 facing the latch opening 44 is greater than a height 49 of a side 50 facing away from the latch opening 44. In other words, the tongue opening 40 has a tapering shape extending from the latch opening 44 on. The advantage of a tapered shape of the tongue opening 40 is associated with the 6A and 6B explained.

The pawl opening 44 also has a substantially rectangular shape. On a side 52 facing away from the tongue opening 40, the pawl opening 44 also has a tapering extension 54, into which the locking pawl 42 hooks. The pawl opening 44 thus has a height 55 on the side 52 facing away from the tongue opening 40, which is less than a height 56 of the remaining pawl opening 44. At the transition to the extension 54, the pawl opening 44 also has convex curves 57, that is to say curves that extend from the frame member 32 into the pawl opening 44. The curves 57 together with the extension 54 allow the locking pawl 42 to engage securely in the Pawl opening 44 and lateral guidance of the locking pawl 42 when engaging in the pawl opening 44.

Fig. 5 now shows a side view of the grip element 35. The grip element 35 has an elongated main body 60 which extends along a longitudinal extension axis (longitudinal axis) 62. The grip element 35 has a locking section 64 at its front end and a grip section 66 at its rear end.

The locking section 64 is designed to engage in the mounting section 45. The locking section 64 has the tongue 38 and the locking pawl 42 shown in a cutout.

The locking pawl 42 has a hook-shaped projection 67 and is rotatably mounted in the elongated main body 60 via a pin 68. The locking pawl 42 is between a locking position that in the Fig. 5 is shown with solid lines, and a release position (unlocking position), which in the Fig. 5 is shown by dashed lines, movable. In the locking position, the locking pawl 42 engages in the pawl opening 44 such that the hook-shaped projection 67 in the extension 54 (see Fig. 4 ) intervenes. In the release position, the hook-shaped projection 67 is disengaged from the extension 54, so that the locking pawl 42 can be removed from the pawl opening 44. To move the locking pawl 42 between the locking position and the release position, the grip element 35 has an actuating element 70 connected to the locking pawl 42.

The hook-shaped projection 67 also has a beveled surface 69. The beveled surface 69 serves to ensure that when the handle element 35 is moved toward the holding section 45, the hook-shaped projection 67 moves from the release position in without the actuation element 70 being actuated moves the locking position so that the hook-shaped projection 67 is automatically locked in the locking opening 44.

The grip element 35 also has two lateral guide projections 72, which extend laterally from the elongated main body 60 near the locking pawl 42. The guide projections 72 serve for the lateral guidance of the grip element 35 when the tongue 38 engages in the tongue opening 40 and the locking pawl 42 in the locking opening 44. Furthermore, because the guide projections 72 overlap at least partially laterally with the locking pawl 42, the locking pawl 42 can also move between the locking position and the release position are guided laterally. The lateral guidance thus not only facilitates the positioning of the locking pawl 42 in the pawl opening 44 but also the insertion of the tongue 38 into the tongue opening 40. Furthermore, the stability and rigidity of the grip element 35 is improved by the lateral guide projections 72.

The tongue 38 is connected to the elongated main body 60 at a front end of the elongated main body 60. The tongue 38 has a substantially arcuate shape in a first plane parallel to the longitudinal axis 62 and extends essentially along the longitudinal axis 62. The elongated main body 60 also has a bore 74 at its front end adjacent to the tongue 38. The bore 74 is designed to receive the pivot pin 36 so that the tongue 38 can be inserted into the tongue opening 40 and the locking pawl 42 into the locking opening 44 by rotating the grip element 35. If there is also a further tongue at the upper end of the pivot pin 36, the further tongue can also be inserted into a tongue opening which is correspondingly formed, for example, on the roof rail by rotating the grip element 35.

In the Fig. 5 the pivot 36 is shown schematically by a dashed line. As can be seen, the pivot axis 75 of the pivot 36 is arranged eccentrically to the bore axis 76 of the bore 74. The eccentric arrangement enables the distance between the pivot point of the grip element 35 and the frame element 32 to be variably adjusted. In this way, a position of the tongue 38 and a position of the locking pawl 42 can be adapted such that an engagement of the tongue 38 in the tongue opening 40 and an engagement of the locking pawl 42 in the pawl opening 44 can be adapted to the particular circumstances on the truck trailer 10. For example, due to the eccentric mounting of the grip element 35, a constructional delay, manufacturing tolerances or the like can be taken into account, so that an optimal engagement of the tongue 38 in the tongue opening 40 and an optimal engagement of the locking pawl 42 in the pawl opening 44 can be ensured. The eccentric arrangement of the pivot pin 36 to the bore 74 can be carried out, for example, by an eccentric (not shown) connected in between.

For the sake of good order, it should be noted that a panel can preferably be provided which has the hole pattern with the openings for the tongue and the latch and is slidably attached to the frame.

Like in the Fig. 5 As shown, the arcuate shape of the tongue 38 has a first arcuate portion 78 and a second straight or elongated portion 80. The arcuate portion 78 extends laterally from the elongated main body 60 and toward the front end of the grip member 35. The straight portion 80 extends from the arcuate portion 78 substantially along the longitudinal axis 62 and with its front end projects beyond a front end of the elongated main body 60. The straight section 80 also has a widening or thickening 82 at its front end. In other embodiments, the exact shape the tongue 38 may be slightly changed. However, all embodiments have in common that the shape of the tongue 38 is designed such that an early non-positive connection between the tongue 38 and the frame element 32 takes place when the tongue 38 engages in the tongue opening 40.

The tongue 38 can be formed in one piece with the elongated main body 60 and can be formed, for example, by laser or another suitable method.

In the Figure 6A the grip element 35 is shown in a top view. The top view represents a second plane perpendicular to the first plane, ie a plane perpendicular to the side view (see Fig. 5 ). As can be seen, the tongue 38 extends in the longitudinal direction of the main body 60, that is to say along the longitudinal axis 62, and has a shape which tapers in the direction of extension. An example is in the Figure 6A the tongue 38 is shown with a conical shape. However, other tapered shapes are also conceivable.

In the Figure 6B A further embodiment of the grip element 35 is shown, the conical tongue 38 additionally having a wedge-shaped recess 84 at its front end. If the tongue 38 is formed with a tapered or conical shape, the tongue 38 can easily be inserted into the tongue opening 40 of the frame element 32. At the same time, a flat contact of the tongue 38 on the back of the frame element 32 (cf. also Fig. 3 ) ensured.

The tapered shape means that the front, narrower end of the tongue 38 initially on the wider side (page 48 in Fig. 4 ) the tongue opening 40 moves into the tongue opening 40 and is then moved starting from the wider side 48 to the narrower side 50 of the tongue opening 40. The insertion of the tongue 38 into the tongue opening 40 starting from the wider side 48 towards the narrower side 50 enables an easier one Engagement of the tongue 38 in the tongue opening 40 and can compensate for a frame distortion, for example. In other words, a cooperation of the tapering tongue 38 and the tapering tongue opening 40 enables optimal engagement and positioning of the tongue 38 in the tongue opening 40. This also positions the door.

In the Fig. 5 , 6A and 6B it can also be seen that the locking pawl 42 is connected to the elongated main body 60 via a spring mechanism 86. The spring mechanism 86 causes the locking pawl 42 in its locking position (see, for example Fig. 3 ) is biased. By actuating (pressing) the actuating element 70, the locking pawl 42 is therefore moved from its locking position into the release position, so that the grip element 35 can be rotated and the tongue 38 can be removed from the tongue opening 40.

The grip element 35 can be made from a forged component, cast component or milling component, and the mounting section 45 can be integrally formed in any frame element 32 of the vehicle frame 26 of a truck.

The door locking device 30 according to the invention can be applied to any truck, for example on truck trailers such as semi-trailers or drawbar trailers or on tractors such as tractor units. The door locking device 30 can be attached at the rear, at the side, at the front region, at the roof rail or at other positions of the vehicle frame 26.

In the door locking device 30 according to the invention, the holding section 45 is integrally formed in a frame element of the vehicle frame 26 of the truck. Since the mounting section 45 also closes flat with a side facing the grip element 35, the door locking device 30 according to the invention can prevent that the bracket section 45 is inadvertently damaged when the truck is reset with the doors 22, 24 open. Furthermore, the door locking device 30 according to the invention enables weight and component savings and simplifies maintenance and service work on the door locking device 30.

In some embodiments, the grip element 35 can furthermore have a bore running beneath the actuating element 70, through which a customs cord can be guided in such a way that actuation of the actuating element 70 is not possible. In further embodiments, the inch cord can be passed through the grip element 35 and the frame element 32. Using an inch cord prevents unwanted access to the hold.

The following are based on the 7 to 10 Embodiments of an alarm device 100 according to the invention are discussed in more detail.

Such as B. in the Fig. 7 As shown, 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. In the in Fig. 7 shown oblique view from above, there are in particular two receiving chambers 108 for each a tongue 38 of the previously described door locking devices 30. 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 in the Fig. 7 the receiving chamber 108 shown on the right-hand side has a sensor 112 which projects into the chamber 108. in the In the present case, 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.

In the present case, at least 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.

From the Fig. 8 , which 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. In the embodiment shown, 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.

The Figures 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. In particular, it can be seen where 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.

At the in Fig. 9a shown closed state of the door locking device 30, 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.

At the in Fig. 9b shown position of the door locking device 30, 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.

It should be emphasized that the design of the receiving chambers 108 in conjunction with the narrow access opening 40 for the tongue makes manipulation of the sensor 112 extremely difficult, if not impossible. In particular, it is probably not possible to simultaneously insert a piece of metal when the tongue 38 opens in order to simulate the sensor 112 that the tongue 38 is still at the predetermined minimum distance from the sensor 112.

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. In this embodiment, there is also a charge controller 138, which charges the charge via solar cells 156 Accumulator 114 performs. Alternatively or additionally, 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. It should be noted that the receiving device does not necessarily have to be part of the GPS tracking device. It can also be provided as an independent component. In the event that the tongue 38 is at a minimum distance from the sensor 112, there is no signal output. Should the tongue 38 move away from the sensor 112, 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. At the same time, 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. In particular, not only 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.
