Abstract

A vacuum cleaner comprises a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly provided on the cleaning head and having a hair collection element adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned in a first direction and in a second direction opposite the first direction; and
a hair collection assembly provided on the cleaning head and adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned, the hair collection assembly comprising:
a hair collection element adapted to collect hair from the surface to be cleaned, wherein the hair collection element is positioned exteriorly of the cleaning head;
a mounting assembly for mounting the hair collection element on the cleaning head, wherein the mounting assembly is pivotally coupled to the cleaning head for movement of the hair collection element between a use position in which the hair collection element is in contact with the surface to be cleaned, and a non-use position, in which the hair collection element is spaced from the surface to be cleaned; and
a rotatable coupling between the hair collection element and the mounting assembly, such that the hair collection element can rotate relative to the mounting assembly between a first orientation and a second orientation when the hair collection element is in the use position;

wherein the hair collection element is configured to dig against the surface to be cleaned to collect hair when the cleaning head is moved along the surface to be cleaned in the first direction and the hair collection element is in the first orientation; and
wherein the hair collection element is configured to glide over the surface to be cleaned to release collected hair when the cleaning head is moved along the surface to be cleaned in the second direction and the hair collection element is in the second orientation.

2. The vacuum cleaner from claim 1 , wherein the hair collection element is positioned forwardly of the suction nozzle when the hair collection element is in the use position.

3. The vacuum cleaner from claim 2 , wherein the hair collection element rests atop the cleaning head in the non-use position.

4. The vacuum cleaner from claim 1 , wherein the hair collection element comprises plurality of projections in contact with the surface to be cleaned when the hair collection element is in the use position, wherein the projections are configured to frictionally engage the surface to be cleaned when the cleaning head is moved along the surface to be cleaned in the first and second directions to rotate the hair collection element between the first and second orientations.

5. The vacuum cleaner from claim 4 , wherein the hair collection element comprises a curved face and the projections extend from the curved face.

6. The vacuum cleaner from claim 4 , wherein the plurality of projections comprise elastomeric material.

7. The vacuum cleaner from claim 4 , wherein the plurality of projections comprise at least one set of longer projections and at least one set of shorter projections.

8. The vacuum cleaner from claim 7 , wherein the set of longer projections are provided forwardly of the shorter projections when the hair collection element is in the use position.

9. The vacuum cleaner from claim 1 , wherein the mounting assembly comprises a casing defining a cavity configured to at least partially receive the hair collection element and rotatably coupled with the cleaning head by a pivot coupling.

10. The vacuum cleaner from claim 9 , wherein the rotatable coupling comprises a shafting mounting the hair collection element within the cavity of the casing.

11. The vacuum cleaner from claim 1 , and further comprising a rotatable brushroll for agitating the surface to be cleaned housed within the cleaning head.

12. The vacuum cleaner from claim 1 , wherein the hair collection element comprises a bumper, and the mounting assembly is pivotally coupled to a front portion of the cleaning head, such that in the non-use position the bumper covers the front portion of the cleaning head.

13. The vacuum cleaner from claim 1 , wherein the rotatable coupling comprises an axis of rotation for that the hair collection element that is oriented transverse to the first and second directions.

14. A vacuum cleaner comprising:
a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned in a first direction and in a second direction opposite the first direction; and
a hair collection assembly provided on the cleaning head and adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned, the hair collection assembly comprising:
a hair collection element adapted to collect hair from the surface to be cleaned;
a mounting assembly for mounting the hair collection element on the cleaning head, wherein the mounting assembly is pivotally coupled to the cleaning head for movement of the hair collection element between a use position in which the hair collection element is in contact with the surface to be cleaned, and a non-use position, in which the hair collection element is spaced from the surface to be cleaned; and
a rotatable coupling between the hair collection element and the mounting assembly, such that the hair collection element can rotate relative to the mounting assembly between a first orientation and a second orientation when the hair collection element is in the use position;

wherein the hair collection element is configured to dig against the surface to be cleaned to collect hair when the cleaning head is moved along the surface to be cleaned in the first direction and the hair collection element is in the first orientation;
wherein the hair collection element is configured to glide over the surface to be cleaned to release collected hair when the cleaning head is moved along the surface to be cleaned in the second direction and the hair collection element is in the second orientation; and
wherein the hair collection element comprises a curved face and a plurality of projections extending from the curved face and in contact with the surface to be cleaned when the hair collection element is in the use position, wherein the projections are configured to frictionally engage the surface to be cleaned when the cleaning head is moved along the surface to be cleaned in the first and second directions to rotate the hair collection element between the first and second orientations.

15. The vacuum cleaner from claim 14 , wherein the curved face and the projections comprise elastomeric material.

16. The vacuum cleaner from claim 14 , wherein the plurality of projections comprise at least one set of longer projections and at least one set of shorter projections.

17. A vacuum cleaner comprising:
a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned in a first direction and in a second direction opposite the first direction; and
a hair collection assembly provided on the cleaning head and adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned, the hair collection assembly comprising:
a hair collection element adapted to collect hair from the surface to be cleaned;
a mounting assembly for mounting the hair collection element on the cleaning head, wherein the mounting assembly is pivotally coupled to the cleaning head for movement of the hair collection element between a use position in which the hair collection element is in contact with the surface to be cleaned, and a non-use position, in which the hair collection element is spaced from the surfa
