Abstract:

The invention provides a protective structure which can be used to protect a localized area within home or work place. The invention is especially usable as a protective structure for a sleeping area or for a work table area. The invention includes a rectangular frame, vertical support members and a canopy. The structure is ideally made entirely out of steel or like material. The vertical support members include at each corner, a pair of linear members, such as tubular steel members. Each pair of linear members is in abutment at their upper ends but are spaced apart by several inches at their lower ends. Also, each pair of vertical members is tilted inwardly towards the center of the rectangular frame by about 7 degrees. By these techniques, the support structure is extremely rigid and is extremely resistant to lateral moments. The horizontal members which form the lower horizontal framework and the upper horizontal framework are easily detached and reattached so that the entire structure can be readily expanded or made smaller by simply changing out the several horizontal members for longer or shorter ones.
