Abstract
A release tool is provided to aid in the unlocking of extending towing arms. The tool is adapted to fit a tow bar assembly that has a telescoping towing arm which is locked in an extended position by a slideable collar. The collar is moveable between a locked position and a released position. When in the locked position, the collar holds catches in engagement with legs of the towing arm to hold the legs fixed relative to each other. When in the released position, the legs are free to telescope relative to each other. Stress can build-up in the towing arms making it difficult to move the collar from the locked position to the released position. The release tool of the present invention provides a mechanical advantage to aid in the movement of the collar from the locked position to the released position. A cam surface on the tool engages the collar and moves it from the locked position to the released position as a handle is rotated about a fulcrum means.
