Abstract

A collapsible shield including flat spring frame and flexible sheet material. The frame substantially supporting the sheet material to form a shield. During the folding process for storage, the frames can be formed to a loop configuration by bending and having the ends of each frame held together by any suitable means such as coupling, retaining clip. The loop frames are collapsed by twisting and folding to form a plurality of concentric loop rings and layers of fabric to substantially reduce the size of the shield.

Claims

1. A method of collapsing a shield of the type comprising a fabric cover supported by a frame having at least two flexible coilable flat spring poles;

said fabric cover including a plurality of side panels, a floor panel and a plurality of corners, first and second criss-crossing sleeves for receiving said poles, each sleeve defining a passage having at least one open end for continuous insertion of a pole into the respective sleeve;

each of said poles having opposed ends positioned at said corners;

said method of collapsing comprising the following steps;

joining opposed ends of each pole together by a coupling means to form a closed-loop configuration,

folding the loops and the fabric cover on top of each other,

collapsing said loops by twisting, folding to form a compact bundle of a plurality of loop rings and layers of fabric.
