Abstract

A tile joint brush structure is provided with grout cleaning nodules, which can be used from a standing position, pivotable about a horizontal axis, through vertical, to two oblique extremes at which positive stops are provided. The scrubber brush structure includes a main brush for cleaning one band of the joint, and a laterally adjustably spaced auxiliary nodules for simultaneously cleaning an adjoining band of the joint.

Description

This application emanates from a previous application filing on Apr. 19, 2010, application number 61325454.

FIELD OF THE INVENTION

This invention is directed to disposable brushes and, in particular, to a grout cleaning brush having multiple cleaning nodules and replaceable head.

BACKGROUND OF THE INVENTION

Tile, and equivalent blocky panels used for providing the wear surfaces of floors and walls often are bedded in a cementitious and/or resinous layer of settable or otherwise hardenable material, with some spacing being provided between edges of adjoining panels, which provide exposed joints, in which the bedding material, or a screeded or flowed into place outward extension thereof, is exposed. The exposed outer surface of the joint material may be flush with the wear surfaces of the panels, or (more commonly) outwardly shallowly concave, or otherwise patterned.
The floors or walls may be located within a building, or wholly or partly outdoors.
Most commonly, such wear surfaces require cleaning at least once at the conclusion of the installation process. Depending on the location, cleaning may, from time to time, be thereafter necessary or desirable.
Especially when such surfaces are provided on floors, a common way to clean them is to spread a layer of cleaning solution on the floor, e.g., by pouring or spraying, to swab, scrub or burnish the surfaces using mops, scrubbing machines and/or buffers. While the techniques conventionally used may be quite adequate for efficiently cleaning the exposed surfaces of the tiles, brick or other panels per se, it has heretofore been difficult or impossible to efficiently clean the exposed surface of the joint material. It is not uncommon for the mechanized cleaning of the panel surfaces, to be accompanied by manual, on-hands-and-knees cleaning of the joint surface, using scrub-brushes, and even tooth brushes. Special tile grout cleaning tools have previously been devised by others, but they are designed for cleaning one band of joint surface at a time, and generally are meant to be used while the worker is down on hands and knees.
Thus, it is an objective of the instant invention to provide a disposable grout cleaning head that has multiple brush heads to clean floors and grout simultaneously.

SUMMARY OF THE INVENTION

The strip is 276 mm long and 16 mm wide. It is flat on one side and the base is 1 mm thick. There are 3 rows of nubbins standing on the base. The nubbins are 6 mm tall and 2 mm in diameter. There is a 1.57 mm space between each nubbins in a row. There is a 1.57 mm space between each row of nubbins. The first row of nubbins will begin and end 4 mm from the front edge and back edge of the base, the second row of nubbins will begin and end 6 mm from the front and back edge of the base, the third row of nubbins will begin and end 4 mm from the front edge and the back edge of the base. The first row of nubbins is 2 mm from the left side edge of the base. The total height of the strip is 7 mm. 6 mm for the nubbins and 1 mm for the base.
It is another object of this invention to provide a soft plastic scrubbing strip with 3 rows of scrubbing nodules.
It is still another object of this invention to provide a novel, disposable tile grout cleaning strip for attachment to an existing floor cleaning apparatus described as; 276 mm long and 16 mm wide. It is flat on one side and the base is 1 mm thick. There are 3 rows of nubbins standing on the base. The nubbins are 6 mm tall and 2 mm in diameter. There is a 1.57 mm space between each nubbins in a row. There is a 1.57 mm space between each row of nubbins. The first row of nubbins will begin and end 4mm from the front edge and back edge of the base, the second row of nubbins will begin and end 6 mm from the front and back edge of the base, the third row of nubbins will begin and end 4 mm from the front edge and the back edge of the base. The first row of nubbins is 2 mm from the left side edge of the base. There is a 4.76 mm empty space from the third row of the nubbins to the right edge of the base.
The total height of the strip is 7 mm. 6 mm for the nubbins and 1 mm for the base.

Claims

1. A soft scrubber cleaning brush for simultaneously cleaning exposed joint surfaces between edges of wear surfaces of two neighboring rows of tile, comprising a flat side and an apposing side lined with three rows of cleaning nubbins each of which less than 10 mm tall and 3 mm in diameter.

2. A soft scrubber cleaning brush of claim 1 wherein the cleaning nubbins are spaced less than 2 mm apart.

3. A soft scrubber cleaning brush of claim 1 wherein said rows of cleaning nubbins are spaced less than 10 mm from the front and back edge of said brush base.

4. A soft scrubber cleaning brush of claim 1 wherein a space exists between the 3^rdrow of nubbins and the edge of said brush of less then 5 mm.

5. A soft scrubber cleaning brush of claim 1 wherein the total height of said cleaning brush is less then 10 mm.

6. A soft scrubber cleaning brush of claim 1 wherein said brush is constructed of resin based materials.

7. A soft scrubber cleaning brush of claim 1 wherein the device is easily and removable attached to a Soft Scrubber cleaning mechanism.
