Abstract
The present invention relates in general to a roof construction and more particularly to a roof composed of a main spanning arch or arches above or beneath which other arches or arch sections rotate horizontally for the purpose of covering large areas such as stadiums, arenas, or storage and manufacturing areas, which roof can be moved from an open position where the area is exposed to the weather elements to a closed position wherein the area is shielded from the weather elements.
Claims7
A roof system for covering stadium areas and the like comprising at least one main arch having an apex and lower base legs spanning said open area,
- a substantially circular apex track supported at the apex of the main arch and a substantially circular base track system part of which is supported by the main arch adjacent said base legs,
- a series of one or more arch sections each having an apex portion supported by said apex track and base portion supported by said circular base track system and being movable from closed configuration where the main arch and arch sections close a substantial portion of the stadium area to an aligned-open configuration where the arch sections are supported by the main arch, and
- a second base track system supporting the lower base legs of said at least one main arch where by the main arch and said supported arch sections may be rolled laterally to open the stadium area.
