ABSTRACT:
A device for securing the shafts of buildings, for example light shafts, against forcible intrusion or passage. The device includes at least one hollow blocking bar which spans the shaft transversely and the two ends of which are held in respective anchor members attached to the wall of the shaft with covered bolts and which contains a hollow security rod of substantially the same length. The blocking bar has the form of a polygonal prism the ends of which are received in form-fitting manner in respective recesses of associated respective attachment bases in such a way that they lie in opposing alignment to the mounting bolts of the base and are secured against pull-out by a latch member lock. The device is especially distinguished in that it offers a maximum of security against forcible intrusion while requiring a very small amount of technical and installation effort, by, firstly, giving access to the mounting bolts only after all of the blocking bars have been removed and, secondly, in that the shaping of the blocking bars contributes positively to maintaining the functional security of the components taking part in the anti-intrusion function as long as possible.
