Abstract:
1. A dustpan comprising: a. a body having a front, a lower surface having a front lip at its front, a first sidewall, a parallel oppositely disposed second sidewall, a back having a rear wall and an upper member; b. said lower surface having a first elongated channel extending from adjacent the front lip toward the rear wall, the first elongated channel extending for a given depth into the lower surface and extending for a given height below the lower surface, and a second elongated channel extending from adjacent the front lip toward the rear wall, the second elongated channel extending for a given depth into the lower surface and extending for a given height below the lower surface, the first and second elongated channels being spaced apart and parallel to each other; c. said first sidewall having a first elongated groove which extends from the front of the sidewall toward the rear wall, and having an upper wall which slants at a downward angle from front to back, the first elongated groove having an interior chamber having a given depth and a bulge which extends laterally and outwardly from the first sidewall by a given height, the vertical height of the interior chamber decreasing from a location adjacent the front to the rear of the interior chamber, the vertical height of the exterior bulge also decreases from the front to the rear by the same amount and extending at the same downward angle as the upper wall of the interior chamber; d. said second sidewall having a second elongated groove which extends from the front of the sidewall toward the rear wall and having an upper wall which slants at a downward angle from front to back, the second elongated groove having an interior chamber having a given depth and a bulge which extends laterally and outwardly from the second sidewall by a given height, the vertical height of the interior chamber decreasing from a location adjacent the front to the rear of the interior chamber, the vertical height of the exterior bulge also decreasing from the front to the rear by the same amount and slanting at the same downward angle as the upper wall of the interior chamber; and e. means for holding and carrying the dustpan; f. whereby, when two dustpans are slid together so that one is above the other, the first and second elongated channels of the upper dustpan interlock with the respectively aligned first and second channels of the lower dustpan by having the portion of the elongated channel below the lower surface of the upper dustpan interlocking with the portion of the elongated channel above the upper surface of the lower dustpan, and the first and second grooves of the upper dustpan interlock with the respectively aligned first and second grooves of the lower dustpan where the bulge of each elongated groove of the upper dustpan interlocks with the respective interior chamber of the elongated grooves of the lower dustpan.
