Drainage system for retractable roof
First Claim
1. A retractable roof comprising a pair of spaced parallel rafter assemblies each having a pair of oppositely directed rafters diverging upwardly from a valley to a respective peak, a plurality of guide means extending between said rafter assemblies at spaced locations and including a plurality of spaced parallel wires extending generally parallel to said valley and supported by said rafters, a flexible roof membrane extending between said rafter assemblies and from one peak through said valley to an adjacent peak, said membrane being suspended from said wires of said guide means by hooks at spaced locations and movable therealong between a deployed position in which said membrane extends between said rafter assemblies to cover the area therebetween and a retracted position in which the area between said rafter assemblies is substantially uncovered, one end of said membrane being secured to one of said rafter assemblies and an opposite end being movable toward and away from the other of said rafter assemblies, said one rafter assembly including a formation extending along one side of each of said rafters of said rafter assembly to receive said one end of said membrane, said membrane including an aperture positioned centrally between each of said spaced locations in the portion of the membrane extending through said valley, and a gutter disposed beneath and adjacent to said aperture and extending along said valley to collect water shed from said membrane and passing through said aperture.

Abstract
A roof structure to protect a crop growing area includes a retractable roof membrane or curtain that defines pitched sections of the roof. The membrane extends across the valley between pitched sections and apertures are provided in the membrane to allow water to pass through the membrane. A gutter is disposed in the valley beneath the apertures to collect water and discharge it away from the crop growing area.
