<p>This invention relates to a portable shelter. The shelter includes a shield member, made of sheet material, and a support structure including first and second parallel rails, each in the shape of a portal frame. The rails extend through two series of holes defined along opposite sides of the shield member with the shield member zigzagging across the rails. The shield member is collapsible and expandable along the rails concertina fashion. The shelter provides an operative configuration in which it is supported on its support structure on the ground and its shield member is at least partially expanded and disposed to provide shelter against the sun.</p> |
