Abstract

In order to provide specific information, e.g. concerning emergency exits on ships, in aeroplanes, in buildings, in specific land areas etc. there is provided a device in the form of a profile strip (1) along the path which has to be followed. The profile strip (1) is preferably installed along the walls in the form of a handrail. The profile strip (1) is designed in certain areas for the insertion of information supplying means (2) which may consist of signs and/or light panels and/or sound devices and/or direction indicating lugs or grooves. In the strip there may be cavities for providing any necessary cables for activation of the means.
