Abstract
Die Erfindung betrifft ein Schutzgitter (1), welches aus parallel zueinander angeordneten Gitterstäben (3) und sen krecht zu diesen, ebenfalls parallel zueinander angeordneten rohrförmigen Gitterstäben (2) besteht. An den gegenüberlie genden Enden der rohrförmigen Gitterstäbe (2) sind Licht quellen (4) bzw. Lichtempfänger (5) angeordnet, so daß das Licht von den Lichtquellen (4) durch den Hohlraum der rohrförmigen Gitterstäbe (2) zu den Lichtempfängern (5) gelangt. Bei Unterbrechung des Lichtstrahles wird win Alarm ausgelöst. The invention relates to a protective grille (1), which consists of parallel bars (3) and sen perpendicular to these, also arranged parallel to each other tubular lattice bars (2). At the opposite The ends of the tubular bars (2) are light sources (4) or light receiver (5) arranged so that Light from the light sources (4) through the cavity of the tubular lattice bars (2) to the light receivers (5) reached. If the light beam is interrupted, win alarm triggered.
