DE102011010537A1 - Immobilizer for e.g. semi-trailer that is utilized with e.g. tractor, has fuse block arranged on semi-trailer such that terminal block of semi-trailer is lockably accommodated within block, where block is locked by electronic code lock - Google Patents

Abstract

The immobilizer has a fuse block (1) arranged on a semi-trailer or a trailer such that a terminal block of the semi-trailer or the trailer is lockably accommodated within the fuse block. The terminal block is provided with air-tight electrical connections. A base part (10) of the fuse block is firmly mounted at the semi-trailer or the trailer. An upper cover (20) of the fuse block covers the terminal block when the semi-trailer or the trailer is parked. The fuse block is locked by an electronic code lock (30).

Description

The present invention relates to an immobilizer for semi-trailer and trailer referred to in the preamble of claim 1 Art.

State of the art

The increase in theft of parked and valuable cargo loaded truck trailers and truck semi-trailers (hereafter referred to as a trailer) makes it imperative to provide appropriate facilities that effectively prevent unauthorized removal of the trailers. In order to prevent theft, numerous solutions have been proposed in the past to ensure that the attempt to unauthorized removal, for example, by means of acoustic and / or optical warning devices is already prevented. However, these facilities have proven to be less effective. From the prior art anti-theft devices are also known, which are intended to prevent both the unauthorized coupling and uncoupling of a trailer and the theft of a standalone trailer.

Out EP 1 008 469 D1 . DE 85 19 623 U1 and DE 89 09 872 U1 For example, safety devices are known by means of which the coupling housing of a ball-and-socket coupling is enclosed in such a way that placement of the ball-and-socket coupling on the ball is prevented. DE 20 2004 010 190 U1 describes such a device, which consists of a fuse box, which is formed of two half-shells, which are pivotally connected to each other by a hinge. Out DE 2005 000 091 U1 is an anti-theft device with cylinder lock and key for semitrailers with spring brakes known in which the housing is firmly connected to the trailer frame.

In DE 10 2006 042 925 A1 an immobilizer for trailer vehicles is described, which is connected to the electronic brake system and a brake system of the trailer vehicle, wherein an operating device for activating and deactivating the protection is provided by means of the brake system.

DE 29 501 043 U1 further describes an electronic security device for trucks in which a switching means having arrangement, by which the locking or release function of a provided on the truck fastening element for a cargo container and / or a coupling system for a charge transport serving hanger so controllable in that when the power supply is interrupted via a supply line and / or a conducting connection between one or more wires of the supply line or with the vehicle ground as a result of damage, the fixing element and / or the coupling system are in a locked state locking the charge be set.

The disadvantage of the safety systems and immobilizers known from the prior art consists primarily in the fact that they have not been proven in practice, since they are either too technically complex designed and therefore difficult to handle and / or be leveraged by simple measures can.

Presentation of the invention

The present invention is based on the object to provide an immobilizer, which is simple in construction terms and easy to use and which ensures a high level of security against unauthorized removal of trailers or trailers.

According to the invention the above object is achieved with the features of claim 1. Advantageous embodiments of the immobilizer according to the invention are specified in subclaims.

Thereafter, an immobilizer of the type mentioned is characterized in that the fuse box on the trailer or trailer (both hereinafter uniformly referred to as trailer) is arranged such that the terminal block of the trailer with the luffing and electrical connections within the fuse box to prevent unauthorized access closed is housed.

The fuse box consists essentially of two components, the lower part, which is firmly mounted on the trailer and the upper part (a cover, a lid), which covers the terminal block with the luff and electrical connections, which is located within the base, with the trailer off and thus protects against unauthorized access. The upper part is preferably stored in the driver's cabin while driving and carried hanger. After placing the trailer, the fuse box is closed by means of the entrained upper part.

Preferably, the closure of the fuse box by means of a - particularly advantageous electronic - code lock. The (electronic) code lock has the advantage that it can be opened without the use of a key. Therefore, only the code must be passed on to the person who is to be authorized to open the lock. The passing / sending of a key is therefore not required. Particularly preferably, the assignment of the code to the number assigned to the carrier / forwarder (delivery number / carrier number) can be linked.

In order to reach the connection strip, in a preferred embodiment of an electronic code lock, current must be passed from the tractor to the code lock arranged on the fuse box. After entering the correct numerical code, the built-in code lock opens a lock and the lid can be opened. After removal of the upper part there is free access to the terminal strip, the trailer is now ready to drive again. To simplify the supply of electricity may be disposed on the fuse box preferably a socket.

Brief description of the drawings

Other objects, features, advantages and applications of the immobilizer according to the invention will become apparent from the following description of an embodiment with reference to the drawings. All described and / or illustrated features, alone or in any combination form the subject matter of the invention, regardless of the summary in individual claims or their dependency.

In the drawings show

3 the immobilizer as in 1 in perspective rear view, from below.

Embodiment of the invention

1 shows the immobilizer according to the invention in a perspective front view in a preferred embodiment. How out 1 can be seen, there is the fuse box 1 in this embodiment of a lower part 10 which is a floor plate 11 , a side plate 12 and a back plate 13 has and a cover 20 , consisting of a lid 21 , a side plate 22 and a front panel 23 ,

The cover 20 is for attachment to the lower part preferably in guides 14 on the lower part 10 introduced and then by means of the electronic code lock 30 locked. The guides 14 ensure that the fuse box 1 Secured on the other hand against unauthorized access, for example. By means of a bending or breaking tool.

The lower part 10 is reversibly or irreversibly fixed to the trailer, for example by means of screw or otherwise by means of one or more fasteners. Particularly preferably, the connecting elements are exclusively within the fuse box 1 accessible to prevent the fuse box 1 can be removed without authorization from the trailer. To avoid this, it also lends itself as an additional measure, the terminal block with the air and electrical connections within the fuse box 1 to fix.

lower part 10 and cover 20 of the fuse box are preferably made of a stable sheet metal. Of course, other secure against burglary materials come into consideration.

To the cover 20 from the lower part 10 easier to solve, is on the cover 20 a handle on the back 24 intended. The handle also facilitates the transport of the cover 20 to the driver's cab to carry it while driving.

This is advantageous for closing the fuse box 1 provided electronic code lock 30 attached to the cover. So those at the code lock 30 located locking parts and the electronics, with the fuse box closed safely inside the fuse box 1 are located while driving and open fuse box 1 not affected by external weather conditions such as rain, snow, ice etc.

The immobilizer according to the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of design variations are possible, which make use of the solution shown even with fundamentally different type of execution.
