Description

The invention relates to an anti-theft device

Device for tow ball couplings of vehicle trailers.

So far, it has been common practice to use a pull-swivel handle Ball couplings for car trailers such as boat trailers, horse boxes, caravans and the like in the coupled state by an in the locking device to secure plug-in lock, so that a closed once established Coupling cannot be opened by unauthorized persons.

The disadvantage of this anti-theft device is that that the vehicle trailers are not secured against theft when uncoupled, since the plug lock cannot intervene in this position of the coupling and is taken by the owner along with the key.

The invention is based on the object of providing a motor vehicle trailer in coupled as in the uncoupled state secure against theft.

This object is achieved according to the invention by a padlock with high bracket, one that can be connected to the high bracket of the padlock on both ends, the closing strap or chain and a pair of holes wrapped around the trailer drawbar at the free end of the pull-swivel handle of the coupling half on the drawbar side for Inserting the high padlock shackle.

According to a further developed embodiment of the invention takes place In addition, nooh a plug-in pipe with one edge recess and two transverse to the plane of symmetry the edge recess running pairs of holes application, which an anti-theft device of the uncoupled vehicle trailer with the D in the open position on the drawbar side Coupling half.

In the following, both embodiments are shown in FIG Side view in almost natural size explained in more detail.

He show 1 Figure 1: the embodiment of the anti-theft device, which is only used in the closed position of the coupling half on the drawbar side can be and Figure 2 t the embodiment, in which the drawbar-side coupling half the uncoupled vehicle trailer can be secured in the open position.

According to the representation given in FIG. 1, the coupling half is 3 attached to the Deichs-l 13 by means of the fastening screw 7. The pull-swivel handle 6, which is pulled out in the direction of arrow 1 and pivoted in the direction of arrow 2 is moved the clamping jaw 3 once into that shown in Figure 1 on the vehicle side spherical coupling half 4 including position and on the other hand in the in Figure 2 shown open position.

In the embodiment shown in FIG. 1, a locking chain is wrapped around it 17 the trailer drawbar 13 and is one with both ends with the high bracket 14 Padlock 15 connected. The latter is with its high bracket 14 in the @@ free End of the pull-swivel handle 6 arranged hole pair (16,16) inserted.

By the so tensioned locking chain 17 is coupled like in the uncoupled state prevents movement of the pull-swivel handle 6, so that any disengagement or engagement process is excluded.

In the embodiment shown in Figure 2, a push-in pipe is used 8 to the application, which the drawbar-side coupling half 3 with pivoted up Pull-swivel handle 6, that is, fixed in the open coupling position. To this end one free end of the plug-in tube 8 is extended to the one that is extended by a sleeve 12 Fastening screw 7 is set and then the pairs of holes (10, 10) of the Plug tube 8 and 16, 16 of the free end of the pull-swivel handle 6 to each other brought into alignment, so that the high bracket 14 of the padlock 15 is used and can be closed. This prevents the pull-swivel handle 6 from the open position shown in FIG. 2 into the closed position shown in FIG is pivoted back.

With regard to the push-in tube 8, FIG. 1 shows that the free end of the pull-swivel handle 6 in a different way into the edge recess 9 of the Steok tube 6 is inserted in such a way that another pair of bores 11, 11 of the plug-in pipe 8 is aligned with the pair of holes 16, 16 of the pull-swivel handle 6.
