Abstract:
The double action push broom of the present invention includes a dynamic double action dual brush head and a broom handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action push broom stores kinetic energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.
