ABSTRACT:
A structural protective shelter designed to be used around and above beds, office chairs, or anywhere an occupant may be sitting, standing, or reclining. It is ideally suited for protective use against structural building collapse resulting from disasters such as earthquakes, tornadoes, hurricanes, bomb blasts, etc. The shelter is ideally made of steel or like material and is comprised of a rectangular continuously framed base (18) from which rise four, vertical uprights (14), two pair becoming continuous to radiused corners and common overhead horizontal primary members (20). Between and perpendicular to said two overhead primary members is attached two horizontal overhead cross members (10). Between and perpendicular to said two overhead cross members is attached a handle bar grip (12) to be used to help an occupant to maintain position within the shelter during periods of violent movement. X-bracing is attached between one pair of verticals which share a common overhead primary member (22) and between the two sides of the shelter (16 and 24) as well as plate bracing (26) is attached over the rectangle shape formed by the two overhead primary members and the two overhead cross members. The four vertical uprights are designed to repel axial force of falling objects down the length of said uprights, while the bracing systems are designed to repel diagonal and lateral forces against side collapse of said shelter.
