BACKGROUND OF THE INVENTION
The present invention relates to a cleaning tool. In particular, the present invention relates to a floor cleaning tool for removing scuff marks.
Floors, such as terrazzo, vinyl, tile and hardwood, become marred by scuff marks from shoes. Presently, tennis balls are used to remove the scuff marks without damaging the floors. However, using the tennis ball can be inconvenient, especially when the floor covers a large area with many scuff marks, because the individual cleaning the marks must stoop over or kneel on the floor.
- BRIEF SUMMARY OF THE INVENTION
To overcome this, prior art tools have cut cross hairs into tennis balls to insert a handle. However, the handle tends to slip out, and the flexible nature of the tennis ball makes it less than ideal for cleaning scuffmarks. Therefore, there is a need for a better tool for cleaning scuff marks.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention is a tool for removing scuffmarks from floors. The tool includes a felt-type material covering at least part of an inflexible knob. The inflexible knob is connectable to a handle of a floor-cleaning tool.
FIG. 1 is a perspective view of the scuffmark removal tool connected to a handle.
FIG. 2 is a cross-sectional view of the scuff mark removal tool.
FIG. 1 shows is a representative embodiment of scuff mark removal system 10. System 10 includes handle 12 and scuffmark removal tool 14 with inflexible ball 16 and felt-type material 18. Handle 12 connects to inflexible ball 16. Felt-type material 18 covers the outside of inflexible knob 16.
Handle 12 may be from any standard floor-cleaning tool, such as a mop. In this way, a user simply removes the mop head and connects tool 14. This is cost effective as well as creating efficient storage, because only one handle need be purchased and stored. Alternatively, handle 12 may be specifically for tool 14.
Inflexible knob 16 may be made from any of a number of materials and should allow for connection to handle 12, which is described in detail below. Typically, knob 16 has a diameter of about 1-⅜ inches, but knob 16 may be larger or smaller depending on preference and need. One example of knob 16 is a Grainger® ball knob no. 5A013, which has a 1-⅜ inches diameter, ⅜-16 inch thread size, tapped, and made of phenolic plastic.
Alternatively, knob 16 may have a shape other than the spherical shape shown here. For example, knob 16 may be a flat disk, a flat square, or a cube.
Felt-type material 18 may be felt or any similar type of woven material. Felt-type material 18 typically covers about half of the exterior surface of knob 16 but can vary depending on preference and need.
In operation, a user holds handle 12 and places scuffmark removal tool 14 on a floor such that felt-type material is in contact with the scuff mark. The user then rubs the scuff mark with tool 14 until the scuff mark is removed. Alternatively, tool 14 may be used without handle 12.
FIG. 2 shows across section through tool 14. Tool 14 includes knob 16, felt-type material 18, backing 20, adhesive 22, and insert 24. Material 18 is the outermost layer. It is attached to backing 20, which is in turn attached to knob 16 with adhesive 22. Insert 24 extends into knob 16 from a location opposite material 18, if material 18 does not completely cover knob 16 as shown here.
An example of a suitable adhesive 22 is Devcon® 2-Ton epoxy. Backing 20 is typically composed of rubber or similar type material and prevents adhesive 22 from seeping through material 18. Examples of suitable felt-type material with a rubber backing are the covering of a tennis ball or non-slip felt grip for fishing waders. A felt material that would not require rubber backing is industrial felt material, which is thicker and would prevent seepage of glue.
Insert 24 allows connection of a handle. Insert 24 is a metal sleeve that is a ¼ inch 20NC, which is standard for attaching a handle-especially the handle of a standard floor-cleaning tool. Insert 24 allows tool 14 to be securely attached to a handle while still being easily attached and detached.
Tool 14 quickly and easily removes scuffmarks from floors. Because tool 14 attaches to handles of standard floor-cleaning tools, it is cost effective and requires little additional storage space. In addition, the materials described above for fabricating tool 14 are substantial to provide repeated use without wearing out.
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
