Abstract

In one embodiment, a vacuum attachment for reaching smaller spaces has a gasket and narrow tubing. The gasket includes i. a cap member sized to fit over an open end of a vacuum hose, the cap member having an inner surface and a central hole to accommodate a narrow tube; ii. inner wall members extending from the central hole of the cap and gripping the narrow tube; and iii. outer wall members extending from the cap member perimeter to a distal edge and accommodating the vacuum hose, the wall members having an internal surface with ribs that extend from the distal edge of the wall members to and on the inner surface of the cap. The at least one narrow, bendable tube is fashioned to fit into the central hole of the cap member and has sufficiently thick walls to avoid collapse when a vacuum is applied thereto.

Claims

1. A vacuum attachment for reaching smaller spaces, the attachment comprising

a. a gasket comprising

i. a cap member sized to fit over an open end of a vacuum hose, the cap member having an inner surface and a central hole to accommodate a narrow tube;

ii. inner wall members extending from the central hole of the cap and gripping the narrow tube; and

iii. outer wall members extending from the cap member to a distal edge and accommodating the vacuum hose, the wall members having an internal surface with ribs that extend from the distal edge of the wall members to and on the inner surface of the cap; and

b. at least one narrow, bendable tube fashioned to fit into the central hole of the cap member and having sufficiently thick walls to avoid collapse when a vacuum is applied thereto.

2. The at least one narrow tube of claim 1, being thick-walled and flexible and comprising vinyl or polyethylene.

3. The vacuum attachment of claim 1 wherein the attachment provides four narrow tubes, a first tube that fits inside the inner wall members, a second tube that first inside the first tube, a third tube that fits inside the second tube and a fourth tube that fits inside the third tube.

4. The first tube of claim 3 being about two feet in length, and about 1.6 cm (⅝

inch) interior diameter and fitting into the central hole of the cap member.

5. The second tube of claim 3 being about one foot in length and having a 1.3 cm (½

inch) interior diameter.

6. The third tube of claim 3, having a length of about one foot and an interior diameter of about 0.95 cm (⅜

inch).

7. The fourth tube of claim 3, wherein the tube has a length of about one foot and an interior diameter of about 0.7 cm (¼

inch).

8. The gasket of claim 1 comprising thick rubber.

9. The gasket of claim 1 being provided in two outer wall diameters to accommodate vacuum hoses of about 3.2 cm (1-¼

inch), 3.8 cm (1-½

inch), 4.8 cm (1-⅞

inch) and about 6.35 cm (2-½

inch).

10. The gasket of claim 1 further comprising a middle wall between the inner wall and the outer wall members, the middle wall stiffening the gasket for more convenient operation.

12. The at least one narrow tube of claim 1, further comprising vinyl or polyethylene and being thick-walled and flexible.

13. The vacuum attachment of claim 1 wherein the attachment provides four narrow tubes, a first tube that fits inside the inner wall members, a second tube that first inside the first tube, a third tube that fits inside the second tube and a fourth tube that fits inside the third tube.

14. The first tube of claim 13 being about two feet in length, and about 1.6 cm (⅝

inch) interior diameter and fitting into the central hole of the cap member.

15. The second tube of claim 13, being about one foot in length and having a 1.3 cm (½

inch) interior diameter.

16. The third tube of claim 13, having a length of about one foot and an interior diameter of about 0.95 cm (⅜

inch).

17. The fourth tube of claim 13, wherein the tube has a length of about one foot and an interior diameter of about 0.7 cm (¼

inch).

18. The gasket of claim 1 comprising thick rubber.

19. The gasket of claim 1 being provided in two outer wall diameters to accommodate vacuum hoses of about 3.2 cm (1-¼

inch), 3.8 cm (1-½

inch), 4.8 cm (1-⅞

inch) and 6.35 (2-½

inch).

11. A vacuum attachment for reaching smaller spaces, the attachment comprising

a. a gasket comprising

i. a cap member sized to fit over an open end of a vacuum hose, the cap member having a top surface and a central hole to accommodate a narrow tube, the top surface having at least one hole to relieve pressure;

ii. inner wall members extending from the central hole of the cap and gripping the narrow tube;

iii. outer wall members extending from the cap member and accommodating the vacuum hose; and

b. at least one narrow, bendable tube fashioned to fit into the central hole of the cap member and having sufficiently thick walls to avoid collapse when a vacuum is applied thereto.

20. The gasket of claim 11, further comprising a middle wall between the inner wall and the outer wall members, the middle wall stiffening the gasket for more convenient operation.
