ABSTRACT:

FIELD OF INVENTION
This invention relates to a portable windbreak for use, for example, by ice fishermen and the like.
BACKGROUND OF INVENTION
Portable, folding, screens and windbreaks are, of course, well known in the art. Attention is directed, for example, to U.S. Pat. Nos. 5,730,666; 4,971,089 and 4,870,984 which all describe some form of folding, portable sun and/or windscreen which can be simply erected or stowed. Such devices usually incorporate a collapsible metal rod frame over which a canvas or plastics material cover can be attached. These devices are, however, relatively cumbersome and not particularly well adapted for single handed erection nor are they very stable in strong wind conditions. There is a need, therefore, for an improved portable windbreak which can be quickly and easily erected by one person and which will be effective and stable when mounted on an ice surface for use in strong winds such as often pertain during such activities as ice fishing or judging skating or skiing events and the like.
OBJECT OF INVENTION
It is an object of the present invention to provide a portable and collapsible shelter which can be erected by one person and which can be used in strong winds on an ice surface.
BRIEF DESCRIPTION OF INVENTION
By one aspect of this invention there is provided a portable and foldable shelter comprising:
a hinged combination of three substantially rigid pole members, lying in substantially planar parallel relationship when in a folded position, having a hinge member at one end thereof arranged so that two outer pole members may be extended angularly to each other and a central pole member may be extended perpendicularly thereto so as to form a tripod when in an extended position;
a flexible, planar cover member attached longitudinally along the length of each of said pole members so as to provide a windbreak when in said extended position;
and ground securing means mounted on a second end of said central pole member.
