ABSTRACT:
An exercise and stress-relief device is disclosed comprising a bending tube and a cover. The bending tube comprises a spring and a friction element. Application of an increasing bending force results in the reduction of the radius of curvature of the device. Removal of the bending force results in the device maintaining its shape if the radius of curvature is greater than or equal to the critical radius of curvature. A reversed bending force is required to straighten the device at a radius of curvature greater than or equal to the critical value. At a radius of curvature less than the critical value, the device acts in a conventional spring manner. The preferred embodiment of the device comprises a resilient foam cover and end caps. It can be used as a hand exerciser in short lengths or an arm/upper torso exercise device in longer lengths. The device provides a stress-reduction function from its novel bending mode.
