Abstract (en)
[origin: US4628646A] 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.
