ABSTRACT:
The Back Jack is an upper body support to be used when a person is working on their hands and knees. The Back Jack has a base with a chest pad on one side and a support rod pivotally mounted on the other side. The chest pad is made of a high quality or memory foam and covered with a vinyl material. The support rod pivot joint can be locked in a working position perpendicular to the base, a transport position parallel to the base, and one or more intermediate positions. The support rod is made of telescoping sections to accommodate workers of different heights. The telescoping sections are adjusted by a spring pin fixed to an inner shaft which fits through holes in an outer shaft. A pivoting rubber foot is mounted to the bottom of the inner shaft.
