Abstract

An accessory tool for use with a suction source has a housing having a suction outlet and a suction nozzle. A hair collection element is pivotally mounted within the suction nozzle for movement between a forward position and a rearward position. The hair collection element can be in the form of a blade and a hair collecting material mounted to the blade for contacting a surface to be cleaned. Alternatively, an elastomeric material can be coated onto the blade or form the blade itself. Also, the hair collecting material can be formed into the form of the blade without any support other than a rod for mounting the fabric.

Claims (22)

1. An accessory tool for use with a suction source comprising:

a housing comprising a suction outlet and a suction nozzle opening defined by a rim on an underside of the housing, the suction outlet being adapted to be coupled to the suction source; and

a hair collection element pivotally mounted within the suction nozzle opening for movement between a forward position and a rearward position and adapted to contact a surface to be cleaned and to collect hair from the surface during movement of the suction nozzle along the surface at least in one direction, and the hair collection element is positioned within the suction nozzle opening so that the suction nozzle opening is in fluid communication with the suction outlet forwardly and rearwardly of the hair collection element regardless of the position of the hair collection element;

wherein the hair collecting element is configured to pick up hair during one of the forward and backward strokes and is adapted to release hair picked up by the hair collection element during the other of the forward and backward stroke for ingestion by the suction nozzle; and

wherein the suction nozzle is configured to ingest the released hair during the other of the forward and backward stroke.

2. The accessory tool of claim 1 wherein the hair collection element in the form of a blade that has a thin cross-sectional profile and a longitudinal axis along its length, and the hair collection element is mounted for pivotal movement about the longitudinal axis.

3. The accessory tool of claim 2 wherein the hair collection element comprises a strip of directional fabric adapted to collect hair from the surface to be cleaned when the accessory tool is moved across the surface to be cleaned in a first direction and adapted to deposit collected hair from the surface to be cleaned for ingestion by the suction nozzle opening when the accessory tool is moved across the surface to be cleaned in a second direction.

4. The accessory tool of claim 3 wherein the strip of directional fabric is mounted to a surface of the blade.

5. The accessory tool of claim 3 wherein the directional fabric is folded along a length thereof to form the blade.

6. The accessory tool of claim 2 wherein the hair collection element comprises an elastomeric material that is adapted to collect hair from the surface during movement of the suction nozzle along the surface at least in one direction.

7. The accessory tool of claim 6 wherein the elastomeric material is coated onto the blade.

8. The accessory tool of claim 6 wherein the elastomeric material forms the hair collection element.

9. The accessory tool of claim 2 wherein the longitudinal axis is along one longitudinal edge of the profile so that the hair collection element is mounted substantially vertically within the suction nozzle opening.

10. The accessory tool of claim 9 wherein the hair collection element in the forward position forms an acute forward angle with respect to the surface to be cleaned during a backward stroke of the accessory tool and the hair collection element in the rearward position forms an acute backward angle with respect to the surface to be cleaned during a forward stroke.

11. The accessory tool of claim 10 wherein the hair collection element is configured within the suction nozzle to project beneath the rim of the suction nozzle in both the forward and backward strokes.

12. An accessory tool for use with a suction source comprising:

a housing comprising a suction outlet and a suction nozzle opening defined by a rim on an underside of the housing, the suction outlet being adapted to be coupled to the suction source; and

a hair collection element mounted within the suction nozzle opening and comprising a hair collecting material that is adapted to contact a surface to be cleaned and to pick up hair during one of the forward and backward strokes of the suction nozzle and that is adapted to release hair picked up by the hair collecting material during the other of the forward and backward strokes of the suction nozzle for ingestion by the suction nozzle, and the hair collection element is positioned within the suction nozzle opening so that the suction nozzle opening is in fluid communication with the suction outlet forwardly and rearwardly of the hair collection element regardless of the position of the hair collection element;

wherein the hair collection element has a thin cross-sectional profile and a longitudinal axis along its length, and the hair collection element is mounted substantially vertically within the suction nozzle opening; and

wherein the suction nozzle is configured to ingest the released hair during the other of the forward and backward strokes.

13. The accessory tool of claim 12 wherein the hair collecting material is a directional fabric that is adapted to pick up hair only when the suction nozzle moves in only one of the forward and backward strokes and not in the other of the forward and backward strokes.

14. The accessory tool of claim 13 wherein the hair collection element is pivotally mounted within the suction nozzle opening for movement between a forward position and a rearward position as the suction nozzle moves along the surface to be cleaned between the forward and backward strokes.
