"SLEEPING ARK" PROTECTIVE BED

The protective bed contains the base with four wheels and the movable frame, the electric drive, the antimosquito mesh, and two backs with the rolls. The backs are strengthened by the bars attached at the diagonals. At the site where the bars cross, the axial pipe is installed with the ring designed either as the wheel with the spokes or the solid wheel attached on the axis by the nut. The ring is sheathed by the fabric, the thin steel or another material. The backs are joined by the polyhedral bars put into the extended sockets in the backs. The bars are fastened by the nuts. The rings are connected by the plates generating the "pent-roof" operating as the rotating half-cylinder. The gap between the plates in such a construction represents the site of the entry.
