A compound lever mechanism of integral construction comprising a pair of opposed compound levers having common fulcra each compound lever comprising two or more simple first order levers articulated in series, the common fulcra and joints between the simple levers being provided by localized zones of the construction adapted to flex preferentially when sufficient force is applied to the levers. The mechanism is suited for incorporation in a compound lever forceps or like device, thus enabling devices having a scissors action to be formed in one piece, for example as one-shot polypropylene injection moldings. |
