ABSTRACT:
An air isolation hand covering has a bladder consisting of a plurality of interconnected or independent inflation cells that is positioned between the hand and a hand-held tool or other vibrating object. The cells are oriented to permit easy bending of the hand covering in directions appropriate for grasping an object. The effectiveness of the bladder in reducing the vibration energy transmitted to the hand is a function of the shape and configuration of the bladder, the pressure in the bladder, the compressible fluid used, the volume of the bladder, and the grip force and push force used when clasping a tool or other object. The bladder can be filled with air or other fluid during the fabrication of the bladder or it can be inflated or deflated with a small pump and integral air valve connected to one of the air cavities.
