  • Patent number: 10201262
    Abstract: A lobby dustpan is self-standing, self-closing and comprises a lid-handle coupling feature for receiving a broom head for retaining the broom head in the bucket of the lobby dustpan. The lid of the lobby dustpan substantially covers the opening of the bucket when in a closed position. A lobby dustpan is self-standing, wherein the center of gravity is between the outer contact points of the base. In addition, when the lobby dustpan is standing in an upright position on a horizontal surface, the center of gravity of the handle keeps the lid in a closed position. Furthermore, the center of gravity of the bucket is offset from the pivot assembly which causes the bucket to close when the lobby dustpan is lifted up from an open position. The specific geometry of the lobby dustpan enables a combination of features that heretofore are not available with existing lobby dustpans.
