摘要

The arrangement is with a displaceable roof for an outdoor area, such as a sports or external arena, which includes an area for activities which can be thus covered when required. The roof is arched and multi-part, supported, driven and movable along track-forming runners, with corresponding roof parts held at reciprocal distance from each other. It is borne, running with paired collaborating rollers on the runners and driven by a motor. The motor works in conjunction with a cogged bar extending along the movement direction of the roof, allowing the roof parts to move to the required position.
