Abstract
A portable spring leveraged device adapted for attachment to the hips in a manner that allows a person engaged in so-called "stoop labor" to bend or flex at the hips with less physical exertion, and with less stress and strain on involved musculature and vertebral joints. The device consists of a U-shaped metal or plastic frame, hinged in each arm of the U and provided with spring resistance at each hinge point. The frame is belt-mounted at the wearer's waist with the hinge points adjacent the hips and with the bottom of the U and arms providing padded contact at the wearer's chest and thighs, respectively. The two arms provide for independent leg movement for walking while the chest contact resiliently supports a major portion of the wearer's upper torso weight during leaning and stooping, thus relieving the stresses and strains normally imparted to the back muscles, ligamentous and bony support, and especially the low back structure, during, for example, use of a short hoe and/or lifting produce boxes.
