Device for the theft-proof fastening of a number plate to the wall of a motor vehicle

摘要

The invention relates to a device for the theft-proof fastening of a number plate to the wall of a motor vehicle, being composed of at least two screws, the threaded shanks of which in each case project through a bore in the number plate and the heads of which rest against the surface of the number plate. In order to achieve a theft-proof fastening system which is cheap to produce, can be implemented without special technical equipment or the exertion of a large amount of force and ensures that the number plate becomes unusable when it is removed legally or, in particular, illegally, the head of the screw takes the form of a hardened external bar (15) and rests via at least one claw-like projection (16) against the number plate (1), the threaded shanks (14) of the screws project through a profiled, metal supporting plate (3) and are secured on the rear of the latter by means of a lockable nut (17) and the supporting plate (3) accommodates at least four screws (10) which can be secured by their heads (11) in a non-rotating manner on the supporting plate (3), can be inserted into corresponding bores (19) in the wall (2) of the motor vehicle and in each case accommodate in pairs a metal internal bar (20) which is provided with two bores (21) and has, in the region of each bore (21), a cylindrical countersunk area (22) for a single-way nut (23). <IMAGE>
