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.
