Abstract

A cleaning tool for a vacuum cleaner system. The cleaning tool has a manifold disposed therein for more evenly distributing a vacuum-like force produced by the vacuum cleaner system to an undersurface of the cleaning tool, thereby increasing the number of dust and dirt particulates that can be picked up by the vacuum force, and thus increasing the efficiency of the cleaning tool. In a preferred embodiment, the cleaning tool comprises a multi-piece housing within which the manifold resides. The manifold includes a pair of outwardly flaring air passageways and is operable to selectively direct the vacuum force from a vacuum cleaner system more evenly across the undersurface of the cleaning tool to improve the pick-up of dust and dirt particles by the cleaning tool.

Claims

1. A cleaning tool for a vacuum cleaner system, said cleaning tool comprising:

a housing;

a removable lower sole plate operatively associated with said housing and forming an undersurface of said housing, said lower sole plate having a plurality of openings therein;

an independently formed, removable, manifold disposed within said housing, said manifold having a plurality of independent, elongated air passageways, said air passageways each having an outermost end with each said outermost end having at least one opening forming an intake port, each said intake port being in communication with one said opening of said lower sole plate, whereby said lower sole plate operates to help restrict a vacuum airflow through only those areas defined by said intake ports, said manifold thereby being operable to evenly distribute said vacuum airflow across said undersurface of said cleaning tool to help facilitate vacuum pick-up of dust and dirt particles.

2. The cleaning tool of claim 1, wherein said cleaning tool further comprises means for allowing said cleaning tool to pivot vertically in a partially arcuate path, thereby helping facilitate articulation of said cleaning tool during use thereof.

3. A cleaning tool for a vacuum cleaner system, comprising:

a T-shaped housing;

a removable lower sole plate operatively associated with said housing and forming an undersurface of said housing, said lower sole plate having at least one opening; and

an independently formed, removable manifold disposed within said T-shaped housing, said manifold having a plurality of independent, elongated air passageways, said plurality of independent, elongated air passageways each having an outermost end which forms a port, at least one of said ports being in coaxial alignment with said opening in said sole plate, said independent, elongated air passageways and said ports being operable to evenly distribute a vacuum force produced by said vacuum cleaner system through said independent, elongated air passageways and through said openings, thereby helping to facilitate pick-up of dust and dirt particles through said first apertures.

4. The cleaning tool of claim 3, wherein said housing further comprises a pivot arm assembly operable to enable said housing to move in a partially arcuate path relative to said undersurface of said housing.

5. A vacuum cleaner system cleaning tool comprising:

a T-shaped main housing member and a T-shaped lower sole plate member, said lower sole plate member having a plurality of openings disposed therein, said main housing member and said lower sole plate member being adapted to abuttingly engage each other to form a housing assembly; and

upper and lower manifold portions, said lower manifold portion having a plurality of manifold ports therein, said upper and lower manifold portions being adapted to abuttingly engage each other to form a manifold assembly, said manifold assembly being disposed within said housing assembly so as to place said manifold ports in alignment with said openings in said lower sole plate member;

wherein said manifold assembly is operable to selectively direct a vacuum force to said ports to thereby evenly distribute said vacuum force across said loaer sole plate member, thereby helping facilitate pick-up of dust and dirt particles by said cleaning tool.

6. The vacuum cleaner system of claim 5, further comprising a pivot arm adapted to partially reside within a portion of said housing assembly and operable to couple said manifold assembly with an extension wand, said pivot arm being operable to allow said housing assembly to rotate vertically in a partially arcuate path relative to said extension wand and to enable said vacuum force to pass therethrough.

7. The vacuum cleaner system of claim 5, further comprising a floor brush circumscribing said lower sole plate member, said brush being operable to help loosen said dust and dirt particles on surfaces being cleaned.
