ABSTRACT:
An easily deployed barrier 400, shade or shield intended for agricultural or horticultural protection against hail, birds, sunlight, and the like is comprised of open-weave fabric 401 held over the items 402 to be protected so that it tends to assume a rectangular outline when in the fully spread out position and tends to become a slanted parallelogram outline when in the fully closed or contracted position. The shape of the barrier is altered by pulling either cord 411 or cord 410 along one edge along the direction of the length of the cloth. Accessories including supports 403, deposited-load release mechanisms 422, cross-cables 412 for stability, and deployment means 415, 419 are also described. The barriers may be deployed automatically. Barriers of this type can cover large areas such as an entire orchard.
