Abstract
To scrub adjacent parallel grout lines on a tile floor simultaneously, a long handle is attached to a base which is wider than the space between adjacent grout lines. Two or more long narrow scrubbing elements are adjustably mounted on the base with the long sides parallel to one another. They are spaced apart to correspond to the spacing between tiles and locked in position. When they are moved back and forth in a scrubbing motion, they tend to remain in the depressed grout lines so they are self-guiding. All the scrubbing effort is directed to the grout lines which tend to accumulate dirt more than the elevated, impervious tile surface. The scrubbing elements may be bristle brushes, foam or fibrous scrubbing material. An electric motor driven embodiment is shown with rotary brushes adjustably mounted on a rotary shaft.
Claims17
A grout scrubber for scrubbing a plurality of parallel grout lines between floor tiles simultaneously, the scrubber comprising:
- a plurality of individual scrubbing elements, each element having a rigid housing means and extending downwardly therefrom a long, narrow, resilient scrubbing member having a front face wider than the width of said grout lines and opposed sides substantially longer than said front face;
- a base means having a front face substantially wider than the distance between adjacent parallel grout lines;
- a handle attached to said base means and extending upwardly therefrom;
- and
- mounting means for adjustably mounting said housing means on said base means with said scrubbing members extending downwardly and said sides maintained parallel to one another and spaced apart to correspond to said distance between adjacent grout lines.
A grout scrubber for scrubbing a plurality of parallel grout lines between floor tiles simultaneously, the scrubber comprising:
- a housing having a front face substantially wider than the distance between adjacent parallel parallel grout lines;
- a handle extending upward from said housing;
- an electric motor attached to said housing;
- a rotary shaft driven by said motor, said shaft rotatably mounted on said housing parallel to said front face;
- a plurality of resilient, rotary scrubbing means, each having a width greater than the width of a grout line, a diameter substantially greater than said width, and a center hole;
- and
- mounting means for adjustably mounting said scrubbing means on said shaft for rotation therewith and parallel to one another and spaced apart to correspond to said distance between adjacent grout lines.
A grout scrubber for scrubbing a plurality of parallel grout lines between floor tiles simultaneously, the scrubber comprising:
- a plurality of individual scrubbing elements, each element having a rigid housing means and extending outwardly therefrom a long, narrow, resilient member having a front face wider than the width of said grout lines and opposed sides substantially longer than said front face, each said long, narrow, resilient scrubbing member;
- a base means having a front face substantially wider than the distance between adjacent parallel grout lines;
- a handle attached to said base means and extending upwardly therefrom;
- and
- mounting means for adjustably mounting said housing means on said base means with at least a portion of said scrubbing members extending downwardly below,said base means and said sides maintained parallel to one another and spaced apart to correspond to said distance between adjacent grout lines.
