Abstract
A brushroll having bristle tufts of different flexibility suitable to cleaning floor tile and grout between the tile, and for sweeping up debris, including liquid floor cleaner.
Description
- The present invention relates generally to floor cleaning brushrolls, and more particularly to a brushroll intended for use in a machine used to clean grouted tile floors.
- The tile and grout cleaning brushroll of the invention generally comprises two alternating series of V-shaped rows of bristles that form chevron patterns. One series of rows has bristle tufts stiff enough to extend into the grout channels of the floor and clean the grout. The grout cleaning bristles in each row alternate with more flexible bristles that flex when the brushroll is rotated during operation of the machine to thereby provide the flexibility that permits the stiff grout cleaning bristles to get into the grout channels. The other of the two series of bristles is made up of sweeping bristle tufts that are finer and more flexible than the other tufts of the brushroll. The sweeping bristle tufts cooperate in cleaning the tile surfaces and are able to sweep up debris, including liquid cleaner used in cleaning tile floors.
-
FIG. 1 is an elevational view of the brushroll; -
FIG. 2 is an enlarged elevational view of part of the brushroll ofFIG. 1 -
FIG. 3 is an end view taken in the plane of 3-3 ofFIG. 1 ; and, -
FIG. 4 is an end view taken in the plane of 4-4 ofFIG. 1 . - The brushroll of the invention is generally designated by
reference numeral 10. It is comprised of adowel 11 that carries chevron patterns of V-shaped rows of bristles. As shown, the chevron patterns are separated by adrive belt area 12 that is engaged by a belt drive (not shown) of the tile and grout cleaning machine in which the brushroll is intended to be mounted. A ball bearingassembly 13 is at each end of thebrushroll 10. - The chevron patterns are made up of
alternating rows dowel 11. The bristle tufts in each row are equally spaced apart and are staggered toward the center of thebrushroll 10 with respect to the bristle tufts adjacent rows. - In the illustrated example of the invention, each
row 20 is rotated 120 degrees from the end tuft A to the tuft A1 at the apex of the row, and 105 degrees from the tuft A1 to the tuft A2 at the other end of the row. Thus, eachrow 20 is rotated a total of 225 degrees from one end through the apex to the other end. Eachrow 21 is shown to be rotated 105 degrees from its end tuft B to the tuft B1 at the apex and 105 degrees from the tuft B2 at the apex of the row to the end of tuft B3. There is no rotation between the two apex tufts B1 and B2. Thus eachrow 21 is rotated a total of 210 degrees from one end through the apex to the other end of the row. - Each of the
rows 20 has alternatingbristle tufts bristle tufts 25 are stiff enough to penetrate into the grout channels to clean the grout. Thealternating tufts 26 are thinner and more flexible than thetufts 25. Thetufts 26 flex when in cleaning contact with the tile surfaces. The flexibility of thetufts 26 allows thestiffer tufts 25 to get into the grout channels. - The
rows 21 are made up ofbristle tufts 30 that are finer and more flexible than thebristle tufts tufts 30, which cooperate with the other tufts of the brushroll in cleaning tile surfaces, are sweeping tufts that have the capability of picking up debris, including liquid cleaner applied to the tiles as part of the cleaning procedure. Thetufts 30 are longer than thetufts tufts 30 co-act with part of the machine in which the brushroll is mounted so that material swept up by the tufts is caused to fall into a container in the machine. - In a specific example of the invention, the
bristle tufts 20 have a diameter of 0.011 inches, thebristle tufts 21 have a diameter of 0.008 inches, and thetufts 30 have a diameter of 0.006 inches. The ends of thetufts longer tufts 30 are on a diameter of 2.475 inches. In this specific example, the tufts in every row are staggered so that the tufts are displaced 0.156 inches toward the center of the brushroll. - In use, the brushroll is rotatably mounted in a tile cleaning machine and a liquid tile cleaner is applied to the floor. When the machine is actuated, the brushroll is rotatably driven to clean the tiles and the grout between them. At the same time, spent cleaner liquid and debris are swept up by the
bristles 30 and deposited into a container in the machine. - It is contemplated that variations and modifications of the invention will be apparent to those skilled in the art. Therefore, it is to be understood that, within the scope of the appended claims, the invention can be practiced otherwise than as specifically disclosed.
