ABSTRACT:
The present invention relates to a portable, self-anchoring, wind-deflector and shelter structure having a unique configuration so as to employ the impinging wind forces to create the self-anchoring arrangement. The structure is formed with a base member defining a floor having an arcuate rear edge and a longitudinal front edge which forms either a parabolic or hyperbolic configuration, and includes an upright wall being angularly disposed to the base member. The wall is further formed with a compound-curved surface that includes oppositely positioned, tapered, wind channels which allow the wind to blow in a forward and downward direction against the base member, thus causing the structure to be fixed in a stabilized position while subjected to high wind velocities.
