Abstract

A vacuum cleaner attachment has an attachment cylinder and a plate enclosing one end of the attachment cylinder. A semi-rigid tube is attached to and extends from a front side of the plate. A flexible sheet is attached at a centrally located edge to a circumference portion of the attachment cylinder. A hook and loop fastener is attached to outside edges of the flexible sheet so that when the back side of the attachment cylinder is placed over an end of a vacuum cleaner hose, the flexible sheet may be wrapped around the vacuum cleaner hose and the hook and loop faster may be engaged to secure the attachment cylinder in place. Ridges may be provided along a central portion of a length of the tube to adjust the rigidity to the central portion of the tube, and top and bottom scrapper wings are attached adjacent an end of the tube away from the attachment cylinder. Additional, detachable cleaning elements, are also provided that have a securing cylinder of diameter larger than a diameter of the attachment cylinder to enable one end to slip fit over the attachment cylinder, the securing cylinder having axial slots to engage the wings to hold the securing cylinder in place on the attachment cylinder, and bristles carried on the securing cylinder on an end opposite the one end of the securing cylinder.

Claims

1. A vacuum attachment, comprising:

an attachment cylinder;

a plate enclosing one end of said attachment cylinder, said plate having a hole therethrough for airflow through said plate to within said attachment cylinder;

a tube attached to and extending from a front side of said plate, said tube having an interior cavity along its length communicating with the hole in said plate;

a flexible planar member attached at a centrally located edge to at least a portion along a circumference of said attachment cylinder;

a hook and loop fastener attached to outside edges of said flexible planar member, whereby when said back side of said attachment cylinder is placed over an end of a vacuum extension hose, said flexible planar member may be wrapped around the end of said vacuum extension hose and said hook and loop fastener may be engaged to secure the vacuum attachment to said vacuum extension hose.

2. The vacuum cleaner attachment of claim 1 wherein said flexible planar member is a fabric sheet.

3. The vacuum cleaner attachment of claim 1 wherein said tube is of a flexible material.

4. The vacuum cleaner attachment of claim 3 further comprising ridges along a central portion of a length of said tube.

5. The vacuum cleaner attachment of claim 3 wherein said tube is flexible plastic.

6. The vacuum cleaner attachment of claim 3 wherein said attachment cylinder is hard plastic.

7. The vacuum cleaner attachment of claim 5 further comprising top and bottom scrapper wings attached adjacent an end of said tube away from said attachment cylinder.

8. The vacuum cleaner attachment of claim 7 wherein at least one of said scrapper wings is generally triangular shaped and is attached at one side to said tube to stand within a plane encompassing a centerline of said tube.

9. The vacuum cleaner attachment of claim 7 wherein at least one of said scrapper wings is generally triangular shaped and is attached at one side to said tube to stand within a plane encompassing a centerline of said tube, an upstanding edge of said generally triangular shaped scrapper wings being concavely shaped to provide a sharp point on said scrapper wing.

10. The vacuum cleaner attachment of claim 7 further comprising a detachable piggyback attachment comprising, a securing cylinder of diameter larger than a diameter of said tube to enable one end to be emplaced over said tube with a friction fit, said securing cylinder having axial slots to engage said wings to hold said securing cylinder in place on said tube, and bristles carried on said securing cylinder on an end opposite said one end of said securing cylinder.

11. A vacuum attachment for mounting onto a vacuum extension hose, comprising:

an attachment mount including a cylindrical portion and a plate portion, said plate portion enclosing one end of said cylindrical portion, and having a back side for engaging an end of said vacuum extension hose, said plate having a hole therethrough for airflow through said plate to within said cylindrical portion;

a tube extending from a front side of said plate portion, said tube having an interior cavity along its length communicating with the hole in said plate portion;

a flexible fabric sheet winged member attached to said cylindrical portion; and

a fastener attached to said flexible winged member, whereby when said back side of said plate portion is placed adjacent an end of said vacuum extension hose, said flexible winged member may be wrapped around said vacuum extension hose and said fastener may be engaged to secure the vacuum attachment to said vacuum extension hose.

12. The vacuum cleaner attachment of claim 11 wherein said fastener is a hook and loop fastener.

13. The vacuum cleaner attachment of claim 11 wherein said tube is of a flexible material.

14. The vacuum cleaner attachment of claim 13 further comprising ridges along a central portion of a length of said tube.

15. The vacuum cleaner attachment of claim 13 wherein said tube is plastic.

16. The vacuum cleaner attachment of claim 11 further comprising top and bottom protruding tips attached adjacent an end of said tube away from said attachment mount.

17. The vacuum cleaner attachment of claim 16 wherein at least one of said protruding tips is generally triangular shaped and is attached at one side to said tube to stand within a plane encompassing a centerline of said tube.

18. The vacuum cleaner attachment of claim 16 wherein at least one of said protruding tips is generally triangular shaped and is attached at one side to said tube to stand within a plane encompassing a centerline of said tube, an upstanding edge of said generally triangular shaped scrapper wings being concavely shaped to provide a point on said protruding tip.

19. A vacuum attachment for mounting onto a vacuum extension hose, comprising:

an attachment mount including a cylindrical portion and a plate portion, said plate portion enclosing one end of said cylindrical portion, and having a back side for engaging an end of said vacuum extension hose, said plate having a hole therethrough for airflow through said plate to within said cylindrical portion;

a tube extending from a front side of said plate portion, said tube having an interior cavity along its length communicating with said hole in said plate;

top and bottom protruding tips attached adjacent an end of said tube away from said attachment mount, wherein at least one of said protruding tips is generally triangular shaped and is attached at one side to said tube to stand within a plane encompassing a centerline of said tube, an upstanding edge of said generally triangular shaped scrapper wings being concavely shaped to provide a point on said protruding tip;

a flexible winged member attached to said cylindrical portion; and

a fastener attached to said flexible winged member, whereby when said back side of said plate portion is placed adjacent an end of said vacuum extension hose, said flexible winged member may be wrapped around said vacuum extension hose and said fastener may be engaged to secure the vacuum attachment to said vacuum extension hose.

20. The vacuum cleaner attachment of claim 19 further comprising a detachable piggyback attachment, said piggyback attachment comprising, a securing cylinder of diameter larger than a diameter of said tube to slip fit over said tube, said securing cylinder having axial slots to engage said protruding tips to hold said securing cylindrical in place on said tube, and bristles carried on said securing cylinder on an end opposite said one end of said securing cylinder.

21. The vacuum cleaner attachment of claim 19 wherein said fastener is a hook and loop fastener.

22. The vacuum cleaner attachment of claim 19 wherein said tube is of a flexible material.

23. The vacuum cleaner attachment of claim 22 further comprising ridges along a central portion of a length of said tube.

24. The vacuum cleaner attachment of claim 22 wherein said tube is plastic.

25. The vacuum cleaner attachment of claim 19 further comprising top and bottom protruding tips attached adjacent an end of said tube away from said attachment mount.
