Abstract

An attachment for a vacuum cleaning appliance includes a head having a bristle carrier and a bristle cover. The bristle carrier includes a plurality of bristles and the bristle cover includes a plurality of apertures. The attachment includes a conduit which is connectable to a vacuum cleaning appliance for conveying an air flow from the bristle cover towards the appliance, a handle connected to the head, and an actuator which is depressible towards the handle to effect relative movement between the bristle carrier and the bristle cover between a stowed configuration in which the bristles are retracted relative to the bristle cover and a deployed configuration in which the bristles protrude from the bristle cover through the apertures.

Claims (20)

1. An attachment for a vacuum cleaning appliance, comprising:

a head comprising a bristle carrier and a bristle cover, the bristle carrier comprising a plurality of bristles and the bristle cover comprising a plurality of apertures;

a conduit connectable to a vacuum cleaning appliance for conveying an air flow from the bristle cover towards the appliance;

a handle connected to the head; and

an actuator which is depressible towards the handle to effect relative movement between the bristle carrier and the bristle cover between a stowed configuration in which the bristles are retracted relative to the bristle cover and a deployed configuration in which the bristles protrude from the bristle cover through the apertures.

2. An attachment as claimed in claim 1 , wherein the bristle carrier is connected to the actuator.

3. An attachment as claimed in claim 1 , wherein the bristle carrier is integral with the actuator.

4. An attachment as claimed in claim 1 , wherein at least part of the conduit is located within the handle.

5. An attachment as claimed in claim 1 , comprising a device for urging apart the handle and a depressible portion of the actuator.

6. An attachment as claimed in claim 5 , wherein said device for urging apart the actuator and the handle comprises at least one resilient element located between the actuator and the handle.

7. An attachment as claimed in claim 1 , wherein the bristle carrier is moveable relative to the bristle cover, and part of the attachment is configured to restrict movement of the bristle carrier away from the bristle cover.

8. An attachment as claimed in claim 7 , wherein part of the handle is configured to restrict movement of the bristle carrier away from the bristle cover.

9. An attachment as claimed in claim 7 , wherein said part of the attachment is arranged to engage the bristle carrier.

10. An attachment as claimed in claim 1 , wherein the bristle carrier comprises a plurality of rows of bristles, and the bristle cover comprises a plurality of rows of apertures.

11. An attachment as claimed in claim 1 , wherein the bristles are located on at least one bristle pad mounted on the bristle carrier.

12. An attachment as claimed in claim 1 , wherein the head comprises a suction opening of the conduit.

13. An attachment as claimed in claim 12 , comprising a device for varying the air flow into the suction opening.

14. An attachment as claimed in claim 13 , wherein said device for varying the air flow into the suction opening is arranged to vary the air flow into the suction opening depending on the position of the bristle carrier relative to the bristle cover.

15. An attachment as claimed in claim 13 , wherein said device for varying the air flow into the suction opening is arranged to increase the air flow into the suction opening upon relative movement between the bristle carrier and the bristle cover from the deployed configuration to the stowed configuration.

16. An attachment as claimed in claim 1 , in the form of a pet grooming device.
