SHELTER Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: shelter consists of a carcass in the shape of arcs 1 mounted on foundation 2, uncovering roof in the form of rotating bobbin 3 with flexible breadth 5 wound on its axle 4. One end of the breadth is fixed on axle 4 of bobbin 3. The other end 6 of breadth 5 of bobbin 3 is fixed on foundation 2 of the carcass. Arcs 1 of the carcass near foundation 2 are made with undercuttings 7 for placing bobbin 3 in them when the breadth is folded and unfolded. The device is equipped with flexible bendable clamping members 8 mounted over bobbin 3 and outer surface 9 of arcs 1 of the carcass. Ends 10 and 11 of the clamping members are fixed on foundation 2. Being deformed, flexible bendable clamping members 8 lead bobbin 3 between themselves and outer surface 9 of arcs 1 of the carcass and let bobbin 3 roll out over arcs 1 of the carcass when breadth 5 is unfolded and folded. This excludes the operation of "unfastening-fastening" of the clamping members during the shelter servicing and ensures the reliability of the breadth fixing to the carcass arcs. The availability of undercuttings 7 near foundation 2 of arcs 1 of the carcass simplifies the breadth assembling when the bobbin is folded and reduced the loadings on the carcass arcs when the shelter is open and closed with the bobbin weight as in such positions the bobbin interacts only with the foundation on which it can be fixed. EFFECT: simpler design. 4 dwg
