  • Power wave floor squeegee and handle connector
    Patent number: 7185388
    Abstract: One embodiment of the improved squeegee has a front deflector bar, and a plurality of material folding devices that are oriented and positioned on the front deflector bar such that the material encountering the front deflector bar is folded back onto material not yet encountered by the front deflector bar. The front deflector bar has an inside wall with a predetermined configuration and the material folding devices extend from this inside wall. The material folding devices may extend substantially perpendicular from the inside wall or at other angles. The improved squeegee may also have a back support section and a blade. The front deflector bar may be operatively connected to the back support section. The blade may be secured at least partially between the back support section and the front deflector bar.
