Abstract
A central hub carries a main pivotal shaft, on respective sides of which extend pivotal links, to each of which is fixed an end of a truss which trusses can be moved together and parallel when the links are in a straight line for displacement of the structure, and can be spaced and radiating when the links are disposed along a closed contour, for use of the structure.
Claims11
A displaceable openable and closable cover structure comprising:
- a main pivotal shaft (24) which is vertical in position in use of the structure,
- two first links (13) which are horizontal in use and which are each pivotally connected by way of a first end portion about the main pivotal shaft (24) respectively on two opposite sides of the shaft (24),
- a succession of supplementary links (13) which follow each other from each of the two first links (13), the number thereof being determined by the size of the structure, said links being pivotally connected together in twos by way of their end portions, each link (13) having between its end portions a central truss fixing zone (16), the succession of links (13) on each side of the main pivotal shaft (24) respectively terminating with a terminal link (13F, 13G) having a free end provided with a support and fixing means (26, 27) for fixing them to each other when the links (13) have been disposed in a closed contour,
- trusses (4) respectively fixed by one end to a corresponding link (13), to the central zone (16) thereof, and each extending substantially perpendicularly to said link,
- at least one frame (7) extending in use in a vertical plane between two successive trusses (4), each frame (7) being pivotally connected by its opposite ends to the trusses (4) that it connects and itself being pivoted at its centre about a vertical axis (35) to be folding while the frame (7G) which in use connects the trusses (4G, 4H) of the terminal links (13F, 13G) can be dismantled into two portions (7'G, 7"G),
- a jack (8) pivotally connected by way of one end to a link (13) between the two links of each pair of successive pivotally interconnected links, said jack (8) being pivotally connected by way of its opposite end to the corresponding folding frame (7) or to at least one connecting bar (10, 11) pivotally connected to said folding frame (7) and
- removable legs (5A, 5B) which are preferably foldable and which are mounted at the free end portion of certain trusses (4) which are in opposite relationship in use of the structure
