Title Locking arrangement for especially ball-couplings.

The using area of the invention The invention concern an extern locking arrangement especially for trailers and other vehicles or like, with an arrangement of ball-coupling around the drawing arrangement of these.

Known technique Hitherto have one known locking arrangements as an example mentioned in the English PCT application no. PCT/GB94/02678, where one have mentioned a more hands operated locking system, with a locking house and with a separate belonging coupling stanchion or column, with an extern knob for fixing of the house on the pull of the trailer to the extern coupling column.

The disadvantages of this system is that the system is partly difficult to serve.

That will say that it is clumsy and heavy to couple and mount mutual with each other, beside that the mentioned construction for that matter also is relatively expensive to get.

Hitherto have one also known locking arrangement as an example mentioned in US patent no. 1350085. Where the system generally only exist of an open bow, with a through going pawl or tongue, where one then outer can couple a padlock on.

The disadvantages of this system is that it is very easy to break or open, as one only can clip over or cut over the pawl on the padlock.

The technical problem there must be solved With the invention one want to produce or make an extern locking arrangement of the mentioned sort, where one both can use it direct on the arrangement of the pulling rod, and with the same system or arrangement can couple it to extern steady stationary arrangements with different means.

The new technique The new is that the locking arrangement, which generally consist of an U- frame, in its essential exist of one in this generally through going and movable tongue or cross pawl, which in addition cover and block/lock the house of coupling for the trailer or like, qua one for the locking arrangement extern mounted coupling ball or like arrangement, here furthermore in it self has other integrated means or arrangements for an extern locking, as respectively a securing or fixing to generally, as an example, ideal extern stationary fixing arrangements as columns, walls an like fixing points or places.

The invention and specially favourable embodiments has to be explained nearer into details in the following under reference to the figures on the drawing.

The list of figures Fig. 1 shows in perspective a locking arrangement for specially ball- coupling on trailers and like. Where the locking pawl is drawn out from the locking arrangement for an unlocking and a mounting of a coupling house on a pull.

The locking arrangement has in itself integrated a ball for position fixing of the trailer arrangement. The locking pawl can be pulled or drawn over the ball and the house on the trailer coupling, by which the arrangements has to be locked. The locking pawl has to be pulled down to the bottom for automatic stop at a secured covered. As this in the same time have a traversing locking bead mounting holes for a padlock. The end of the locking pawl has a similar hole, so that the locking bow or clamp can go through both holes.

On the head of the locking bow, which for that matter has an angle bent flap, then is this equipped with a locking pin, which can go into a hole on the side of the trailer mount. The pin can perhaps be used for possibly extra chain fixing.

Fig. 2 shows as into Fig. 2 a locking arrangement gather and locked, where there here also can be seen the drawing arrangement itself on the trailer. As the cross pawl here can be seen pushed over this with the ball locked pulling arrangement. And where the cross pawl now lock the whole system. This can be locked for third man by mounting a padlock for the end of the inserted locking pawl, and lock it to the locking bawl itself.

Fig. 3 shows the same arrangement as shown in Fig. 1, but seen direct from the end. There are also shown, how one fixed the trailer with the locking mountings to a column, by mounting a chain into the fix-pin of the locking mountings, and couple it over a column or like.

Fig. 4 shows as in Fig. 3 an arrangement, where one have fixed the locked trailer to a coupling mountings, and this has here also been done via locking pin on the locking bowl.

The mounting of the coupling could either been fixed on the wall, or if only the locking arrangement do not shall be used, then on the side of the trailer or like.

The locking arrangement could also be fixed together with a trailer or like to a column, where the mounting of the coupling could be fixed as an example welded to the end of a column, which so again possibly ideal could be concreted.
