Floor sweeper
First Claim
1. A floor sweeper comprising:
- an elongated handle having opposite top and bottom ends;
a substantially rectangular sweeper head with a front, back, and opposite first and second sides mounted at the bottom of the elongated handle, a front roller mounted on the front for rotation in a first direction;
a rear roller mounted on the rear for rotation in a second direction opposite the first direction;
first and second side rollers mounted on the first and second sides respectively;
the front, rear and side rollers all having sweeping bristles mounted thereon;
at least one front corner brush mounted adjacent to the front and first side, the front corner brush mounted on a shaft for rotating in the same direction as the front roller, the front corner brush extending radially beneath the first side to sweep debris from under the first side toward the first side roller;
at least one rear corner brush mounted adjacent to the rear and first side, the rear corner brush mounted on a shaft for rotating in the same direction as the rear roller, the rear corner brush extending radially beneath the first side to sweep debris from under the first side toward the first side roller; and
debris receiving means for receiving the debris swept by the rollers.

Abstract
A light weight floor sweeper having a very low profile sweeper head that uses glides rather than rollers to slide across the surface to be cleaned. The floor sweeper head is mounted to an elongated handle by means of a universal pivot or universal joint which allows the floor sweeper head to easily pivot about the handle in any direction to pick up debris under over hanging cabinets or under furniture. The floor sweeper has sweeping brushes mounted around all sides of the sweeper head to provide sweeping action in any direction. Furthermore there are corner brushes extending out from the sides of the sweeper head that reach into corners to sweep debris toward the main sweeping brushes. All of the brushes are powered by a small electric motor. The motor drives the brushes to direct the debris into a dust-receiving tray in the sweeper head.

12. A floor sweeper for sweeping a surface comprising:
-
a sweeper head of substantially rectangular configuration having a top and bottom, a front side, a rear side, and first and second opposite sides, the first and second sides intersecting the front side and defining two front corners at the line of intersection, the first and second sides further intersecting the rear side and defining two rear corners at the line of intersection;
a front roller mounted at the front side;
a rear roller mounted at the rear side;
a first side roller mounted at the first side;
a second side roller mounted at the second side;
the front roller, rear roller, first and second side rollers all having sweeping bristles thereon;
debris receiving means mounted on the sweeper head for receiving debris swept by the bristles;

24. A floor sweeper comprising:
-
an elongated handle having opposite top and bottom ends;
a sweeper head with at least a first, a second and a third side mounted at the bottom of the elongated handle, the three sides connected to each other in a triangular configuration to define three corners, one corner at each point of connection of a side to an adjacent side, a first side roller mounted on the first side for rotation in a first debris sweeping direction;
a second side roller mounted on the second side for rotation in a second debris sweeping direction;
a third side roller mounted on the third side for rotation in a third debris sweeping direction;
the first, second and third rollers each having first and second opposite ends, and all rollers having sweeping bristles mounted thereon;
a corner brush mounted on each side adjacent to each corner at opposite first and second ends of their respective side roller, the corner brushes mounted for rotating in opposite directions with respect to each other, each corner brush extending radially beneath the side to which it is mounted and rotating in a direction to sweep debris from under the side toward the center of its respective side roller, and debris receiving means mounted on the sweeper head for receiving the debris swept by the side rollers. - View Dependent Claims (25, 26, 27)

- 28. A floor sweeper adapted to be moved over a surface and clean surface by brushing said sweeper comprising ahead having a plurality of brushes moveably mounted thereon to extend therebelow so as to engage said surface, one of said brushes facing outwardly from said head in a first direction and another of said brushes facing outwardly from said head in a second direction different from but not opposite to said first direction, and moving means operatively connected to said brushes to cause them to move relative to said head.
- 36. A floor sweeper adapted to be moved over a surface and clean that surface by brushing, said sweeper comprising a head having a periphery, a plurality of brushes moveably mounted on said head to extend therebelow so as to engage said surface, said brushes being rotatable about non-parallel axes angularly related to one another, and moving means operatively connected to said brushes to cause them to rotate about their axes.
