Abstract: A cover for servicing holes in automotive service stations consists of a band of pivotably connected support members, the ends of which are supported on the longitudinal hole edges. The band is displaceable longitudinally in opposite directions by at least one motor drive to open and close the servicing hole. During the opening movement the band is moved downwardly at one front end of the longitudinal hole. In order to avoid a broadening of this region of the hole the support members are telescopically assembled and are compressed to a reduced length in this region than in the covering region of the servicing hole.

Abstract: A cover arrangement for a servicing hole comprises a band of a plurality of supporting bars pivotably connected with one another by chains. The band can be drawn into an open position and pushed into a closed position by a reversing motor driving chain wheels which engage with the chains at the band. Guide means at both ends of each supporting bar move along a horizontal U-shaped path which is continuously surrounded by a guiding web structure ensuring that the band is positively guided and cannot buckle even during its pushing motion.
