  • Patent number: 11452429
    Abstract: A hands-free, easy to use, manufacture and assemble upright dustpan with a hinged back door. The dustpan can pivot on the main body and the hinged back-door can be locked or unlocked via a latching mechanism and a trigger, all located on the dustpan's main body. When the latching mechanism is triggered, the hinged back door opens either under its own weight or under the weight of the debris and thus allows debris to leave the compartment and fall into the waste receptacle when the dust pan is held above the waste receptacle in pivoted orientation. The trigger can be actuated by the edge of the waste receptacle, or any rigged body. Whereas the hinged back door can be closed back by tapping on the floor.
