Abstract

An attachment for a hand held appliance comprising a body having a first wall; a second wall; and a slot formed along at least part of the length of the attachment, wherein the slot is defined on a first side by a surface of the first wall and on a second side by a surface of the second wall. The first wall may be generally tubular. The surface of the second wall may be substantially linear. The second wall may extend out from the first wall. The second wall may be moveable or rotatable relative to the first wall. The second wall may be generally triangular. The second wall may have a first indexed position defining a first slot position. The second wall may have a second indexed position defining a second slot position. An indexed position may be defined by a detent mechanism.

First claim

The invention claimed is:

1. An attachment for a hand held appliance comprising a first wall having a first longitudinally extending edge and a second longitudinally extending edge; a second wall extending between the first longitudinally extending edge and the second longitudinally extending edge; a collar for connecting the attachment to the hand held appliance; and a slot formed along at least part of the length of the attachment, wherein the slot is defined on a first side by the second wall and on a second side by at least one of the first longitudinally extending edge and the second longitudinally extending edge of the first wall, the second wall is moveable relative to the first wall, and the first wall or the second wall is stationary relative to the collar by being fixed to the collar and remains stationary relative to the collar as the second wall moves relative to the first wall, and wherein the second wall divides the slot into two.

2. The attachment of claim 1 , wherein the second wall is rotatable with respect to the first wall.

3. The attachment of claim 1 , wherein the second wall extends out from the first wall.

4. The attachment of claim 1 , wherein the second wall has a first indexed position defining a first slot position.

5. The attachment of claim 4 , wherein a first or second indexed position is defined by a detent mechanism.

6. The attachment of claim 5 , wherein the detent mechanism includes an actuator biased into a recess.

7. The attachment of claim 6 , wherein the actuator is a ball bearing.

8. The attachment of claim 6 , wherein the actuator is biased by a spring.

9. The attachment of claim 1 , wherein the second wall has a second indexed position defining a second slot position.

10. The attachment of claim 1 , wherein an external surface of the attachment includes at least one row of bristles.

11. The attachment of claim 10 , wherein the external surface is an external surface of the first wall.

12. The attachment of claim 1 , wherein the first wall or the second wall is fixed directly to the collar.

13. A hand held appliance comprising a handle having a fluid flow path from a fluid inlet to a fluid outlet and a fan unit for drawing fluid into the fluid inlet and an attachment for attaching to the handle, the attachment comprising a first wall having a first longitudinally extending edge and a second longitudinally extending edge; a second wall extending between the first longitudinally extending edge and the second longitudinally extending edge; a collar for connecting the attachment to the handle; and a slot formed along at least part of the length of the attachment, wherein the slot is defined on a first side by the second wall and on a second side by at least one of the first longitudinally extending edge and the second longitudinally extending edge of the first wall, the second wall is moveable relative to the first wall, and the first wall or the second wall is stationary relative to the collar by being fixed to the collar and remains stationary relative to the collar as the second wall moves relative to the first wall, and wherein the second wall divides the slot into two.

14. The appliance of claim 13 , wherein the second wall is rotatable with respect to the first wall.

15. The appliance of claim 13 , wherein the second wall extends out from the first wall.

16. The appliance of claim 13 , wherein the second wall has a first indexed position defining a first slot position.

17. The appliance of claim 16 , wherein the first indexed position is defined by a detent mechanism.

18. The appliance of claim 17 , wherein the detent mechanism includes an actuator biased into a recess.

19. The appliance of claim 18 , wherein the actuator is a ball bearing.

20. The appliance of claim 18 , wherein the actuator is biased by a spring.

21. The appliance of claim 13 , wherein the second wall has a second indexed position defining a second slot position.

22. The appliance of claim 13 , wherein an external surface of the attachment includes at least one row of bristles.

23. The appliance of claim 22 , wherein the external surface is an external surface of the first wall.

24. The appliance of claim 13 , wherein the appliance is a hair care appliance.

25. The appliance of claim 13 , wherein the appliance is a hot styling appliance.

26. The appliance of claim 13 , wherein the first wall or the second wall is fixed directly to the collar.
