Abstract
Abstract A portable windbreak for animals comprising a plurality of panels hingedly joined together for movement between an extended barrier forming position and a retracted folded position. Wheels, laterally connected with the center panel, render the retracted windbreak portable in trailerlike fashion by a tongue connected with one end of the center panel. Erection struts, removably connected with the center panel and a prime mover, raise the retracted windbreak from a horizontal position to a vertical edgewise wind shelter position and vice versa. Ground anchor means, connected with the windbreak, maintain it in an erected position.
