  • Publication number: 20180014631
    Abstract: [Object of the Invention] To decrease the load applied to a spine so as to prevent and treat lumbago, when carrying various shapes of goods with hands. [Solution] A load carrying supporter used for carrying goods by hands, comprising an attachment attached to a worker's body and a load supporter fixed to the attachment. The attachment attached around the worker's waist, and the load supporter has a high frictional resistance material facing outward from the worker's body. Most of the load is lead to the waist and the distance between the loading point and the spine becomes small. Therefore the pressure and the bending moment on the spine become very small.
