Abstract
The closure of the invention for an aperture has strips interlinked articulatedly via hinges in such a way that the distance between adjacent strips defines a space in which the hinge pins engage. Rubber sealing strips are fitted to interconnect adjacent strips; they are arranged coaxially with the hinge pins and engage with the strips virtually without any clearance.
