  • Patent number: 4562611
    Abstract: A long-handled self-dumping dust pan is adapted to be used by a person standing in an upright position. Long-handled dust pans of varying shapes and sizes are known. Those which are automatic dumping however, are complex, heavy and expensive to produce. The present invention overcomes these disadvantages by providing a simple, easy to produce, long-handled dust pan. It is equipped with a lever positioned close to the operator's hand which disengages a detent from a recess in the pan, thereby allowing the refuse to fall into a suitable container.
