<p>The device has a cover supported in guiding profiles, and a safety device (19) comprising a primary circuit (21) with a transmission antenna (27) and a switching device (25). A secondary circuit (23) has a transponder antenna (29) and a switch rail (31). The switch rail is arranged in an area of a transverse edge of the cover. The transponder antenna has a constant distance to the transmission antenna during displacement of the cover in the guide profiles in such a manner that the transponder antenna transfers a signal condition of the switch rail to the transmission antenna.</p> |
