The RoboHandle Adapted Tool Grip removes the wrist strain usually associated with a sweeping, mopping or raking action. People with hand and wrist arthritis will find this ergonomic handle allows them to use stronger bicep and triceps muscles to maneuver long handle tools. The RoboHandle was designed with one simple physical concept: the greater the distance of force arm, the more torque produced by the force. This adapted tool handle has been value-engineered to provide increased torque, thereby increasing leverage, so that relatively large resistance objects such as long brooms, dust pans can easily be moved. The location of the patented supporting ring creates 500% to 600% increase in torque to maneuver hand held tool poles or sporting equipment. An additional benefit is how it helps to absorb the torque to reduce the potential for operator injury to arm, wrist, or hand. Attaching the RoboHandle to tool handles is extremely easy with the two stainless steel clamps. For a more permanent attachment, the handle can be attached using sheet metal screws. The RoboHandle can be attached handles measuring 3/4 inch to 1 inch in diameter such as floor and dusting mops, telescopic window squeegees, paint roller extensions, household push and angled brooms, rakes and brooms.
