Abstract:
A dust pan for collecting a mixture of materials from a flat surface to be cleaned comprising a body member havinga. a bottom wall with a leading contact edge, a rear edge, and a pair of flanking edges,each of the pair of flanking edges extends from an end of the leading contact edge to an end of the rear edge;b. a pair of upstanding side walls, each upstanding side wall has a contact leading upright edge, a side edge, a top edge, a bottom edge, and a trailing edge,each of the pair of upstanding side walls has the contact leading upright edge extending from an end of the bottom edge to a front end of the side edge, a rear end of the side edge is connected to the top edge, the top edge is connected to the trailing edge, and the trailing edge is connected to the other end of the bottom edge;c. a back wall with a top edge, a pair of lateral edges, and a bottom edge,each of the pair of lateral edges of the back wall extends between an end of the top edge and a corresponding end of the bottom edge; andd. a top wall with a trailing border, a pair of sideways edges, and a back edge,each of the pair of sideways edges of the top wall extends between an end of the trailing border and a corresponding end of the back edge,each of said pair of upstanding side walls has its bottom edge connected to one of the pair of flanking edges of the bottom wall, its trailing edge connected to one of the pair of lateral edges of the back wall, and its top edge connected to one of the pair of sideways edges of the top wall,the back edge of the top wall is connected to the top edge of the back wall, andthe bottom edge of the back wall is connected to the rear edge of the bottom wall;e. a recess for receiving the mixture is bounded by the top wall, the back wall, the bottom wall and the pair of upstanding side walls,said recess having an entryway comprising the leading contact edge of the bottom wall, the trailing border of the top wall, and the contact leading upright edges and the side edges of the pair of upstanding side walls,said leading contact edge being flexibly movable between a concave aspect relative to said recess when extraneously unbiased and a substantially straight aspect when biased by pressable contact with the flat surface to be cleaned,whereby, a sealing contact may be made between the leading contact edge of the dust pan and the flat surface to be cleaned to facilitate collection of the mixture of materials from the flat surface.
