摘要

Retractable roofing for covering sports grounds against bad weather allowing sport to be practised at all times and thus preventing events from being postponed. This invention is particularly useful for protecting tennis courts from rain. Play is able to continue despite the rain and the court will always be in good condition. It is also very valuable for European football pitches, where the condition of the pitch often requires the postponement of the event and is harmful for the quality of the sport. A figure numbered one is added in sketch form for a 50 m by 100 m stadium. This figure 1, in sketch form, shows: (1): P = Pylon or Pillar; (2) Lattice girders; (3): Cable; (4): Suspended retractable roofing; (5): Wheel to which the cable is fixed and which moves in a shaped iron attached to the lattice; (6): Drainage of water falling on the roof.
