GROUT CLEANING APPARATUS
An improved grout cleaning apparatus has in line cleaning wheels positioned within a housing, at the terminus of a shaft. A grip is coupled at an upper end of the shaft, and may be grasped by a user to move the apparatus for cleaning purposes. In one embodiment, a drive motor supplies power to the in line cleaning wheels, which may be made to turn in opposing directions so as to provide improved cleaning efficiency. A cleaning fluid dispenser may also provided on the shaft, to permit the dispensing of fluid proximate the cleaning wheels during operation.
This non-provisional application claims priority to provisional application No. 60/919,560, filed Mar. 23, 2007.
FIELD OF THE INVENTIONThe present invention relates generally to the cleaning of tile grout and, more particularly, to an improved grout cleaning apparatus.
BACKGROUND OF THE INVENTIONTile grout is known to be a repository of dirt. It has a tendency to absorb surface dirt, and to become discolored in the process of doing so. That discoloration can be unsightly, and can harm the appearance of an otherwise attractive tile floor.
Cleaning tile grout can be labor-intensive and physically challenging. Many grout cleaning methods require a user to kneel on the floor, and to manually scrub the grout surface, with a toothbrush-type device or sponge, to obtain a cleaning benefit. These approaches may be inefficient, may damage the grout, and/or may be physically uncomfortable for certain persons, and may create an unwanted exposure to contact with or inhalation of a corrosive cleaning solution. As a consequence, people will often forego cleaning of their tile grout, and will instead accept a steady degradation in the appearance of their tile grout.
The present invention is directed to an improved grout cleaning apparatus and method which provides a number of benefits and advantages as compared to the prior art.
SUMMARY OF THE INVENTIONIn accordance with an embodiment of the present invention, an improved grout cleaning apparatus is disclosed. The apparatus comprises, in combination: a shaft having a first end and a second end; a grip coupled at the first end of the shaft; a cleaning housing coupled at the second end of the shaft; and two inline cleaning wheels positioned within the cleaning housing.
In accordance with a further embodiment of the present invention, an improved grout cleaning apparatus is disclosed. The apparatus comprises, in combination: a shaft having a first end and a second end; grip coupled at the first end of the shaft; a cleaning housing coupled at the second end of the shaft; inline cleaning wheels positioned within the cleaning housing; wherein each of the inline cleaning wheels has a brush positioned therearound; and a drive motor adapted to drive the two inline cleaning wheels; wherein the drive motor is adapted to drive one of the cleaning wheels in a clockwise direction and an other of the cleaning wheels in a counterclockwise direction.
In accordance with a still further embodiment of the present invention, an improved grout cleaning apparatus is disclosed. The apparatus comprises, in combination: a shaft having a first end and a second end; a grip coupled at the first end of the shaft; a cleaning housing coupled at the second end of the shaft; two inline cleaning wheels positioned within the cleaning housing; wherein each of the inline cleaning wheels has a brush positioned therearound; a drive motor adapted to drive the two inline cleaning wheels; wherein the drive motor is adapted to drive one of the cleaning wheels in a clockwise direction and an other of the cleaning wheels in a counterclockwise direction; a cleaning fluid dispenser positioned on the shaft, having a dispenser hose coupled thereto, wherein the dispensing hose terminates within the cleaning housing, and wherein dispensing of cleaning fluid from the cleaning fluid dispenser through the dispensing hose is activated by an activator located proximate the grip; a shock absorbing assembly located within the cleaning housing and operable on the cleaning wheels; a plurality of guide wheels positioned along a periphery of the cleaning housing; and a grout alignment guide located on the housing and visible to a user of the apparatus; wherein the grout alignment guide comprises a transparent section, located on the housing, and in alignment with the wheels.
Referring first to
The shaft 14, which may optionally be adjustable in length, is intended to permit a user to operate the apparatus 10 while in a standing position. Coupling between the shaft 14 and housing 18, as shown in
Turning more specifically to
The brush 22 preferably has a width that approximates that of a typical grout line, for example in the range of from about one-eighth of an inch to one-half of an inch or more, recognizing that it should be possible to relatively efficiently use a brush 22 on a grout line that is narrower than the width of the brush 22. The wheels 20 are positioned on axles 24 In one embodiment, shock absorbing springs 26 are interposed between axles 24 and an upper portion of the cleaning housing 18, to permit a user to maintain more even downward pressure during use of the apparatus 10.
As shown in
Referring more specifically to
In one embodiment, the drive motor 28 rotates the wheels 20 in opposing directions, so that one wheel rotates in a clockwise manner and the other rotates in a counterclockwise manner. Such a configuration may prevent the creation of unwanted pull or drag as it is maneuvered along a grout line, and may also provide increased cleaning efficiency. Alternatively, the wheels 20 may both be permitted to rotate in the same direction; i.e., either clockwise or counterclockwise.
Referring now to
It should be noted that instead of providing a fluid dispenser 16 that includes a removable fluid container 19, it may be desired to provide a fluid dispenser that remains mounted to the shaft 14, and that may be refillable thereon.
Referring now to
In operation, a user grasps the grip 12, activates the drive motor 28 (perhaps by depressing power button 29), and maneuvers the apparatus 10 so that the brushes 22 are within a grout line that the user desires to clean. When in position, the user may discharge cleaning fluid via hose 30, perhaps by pulling trigger 32, onto the grout line.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
