Abstract
Multi-positional cleaning devices are provided. The devices have a handle, a blade holder, and a pivoting assembly. The pivoting assembly allows the handle and blade holder to be pivoted with respect to one another about a pivot axis to at least two predetermined angular positions. The pivot axis is parallel to a blade edge. The multi-positional devices can find use with a blade subassembly that has a carriage holding the blade, where the carriage cooperates with the holder to secure the blade in the holder in an easily removable manner.
Claims20
A multi-positional cleaning device, comprising:
- a blade holder;
- a handle;
- a blade with a cleaning edge;
- and
- a pivot assembly securing the handle and the blade holder to one another so that the handle and the blade holder pivot with respect to one another about a pivot axis that is parallel to the cleaning edge,
- wherein the pivot assembly releasably secures the handle and the blade holder in two or more different predetermined angular positions.
A multi-positional cleaning device, comprising:
- a scraper blade with an edge and an opening through the scraper blade;
- a blade carriage having a first protrusion and a second protrusion, the first protrusion extending through the opening when the scraper blade is positioned on carriage in a desired orientation and position;
- and
- a blade holder having a first slot and a second slot, each having an open end on a first edge and a closed end at an opposite edge, the open end of the first slot receiving the first protrusion of the blade carriage so that the blade carriage slides within the blade holder until the first protrusion abuts the closed end of the first slot, and the open end of the second slot receiving the second protrusion of the blade carriage so that the blade carriage slides within the blade holder until the second protrusion abuts the closed end of the second slot.
A method of cleaning a surface, comprising:
- adjusting a cleaning device so that a blade holder has a first angular position with respect to a handle about a pivot axis, the pivot axis being parallel to a cleaning edge of a blade received by the blade holder;
- and
- moving a cleaning edge of the cleaning device across the surface to be cleaned while grasping the handle in the first angular position;
- or
- adjusting the cleaning device so that the blade holder has a second angular position with respect to the handle about the pivot axis;
- and
- moving the cleaning edge of the cleaning device across the surface to be cleaned while grasping an extension pole secured to the handle in the second angular position.
