  • Patent number: 5176622
    Abstract: A hip mounted, springable frame that compresses between the chest and thighs of a worker when he stoops over so as to help the worker to stand erect again and ease back strain. The center of the frame comprises a pair of arc-shape springs that wrap around cylindrical spools of elastomer. The spools are attached to a belt surrounding the worker's waist at hip level. The frame is easily removed and reattached by snapping the springs over the spools. Wear is reduced since there are no moving parts, and the spring forces are adjustable with the use of variable compliance and or springs having different spring constant such as priorities by different spring geometry.
