Cleaning nozzle for a vacuum cleaner
First Claim
1. A nozzle for a vacuum cleaner, the nozzle comprisinga rotatable member for picking up particles from a surface to be cleaned, the rotatable member being arranged to rotate around a longitudinal axis;
- anda cleaning arrangement for removing articles entangled on the rotatable member, wherein the cleaning arrangement comprises;
at least one support surface provided on at least one radially projecting member of the rotatable member, andat least one cleaning member being movable between a resting position in which the cleaning member is arranged at a distance from the support surface and at least one cleaning position in the vicinity of the rotatable member in which the cleaning member, during rotation of the rotatable member, co-operates with at least one segment of the support surface to remove entangled articles from the rotatable member;
wherein the at least one support surface comprises at least a first segment and a second segment, wherein the first segment is arranged at a first radius in relation to the longitudinal axis, the second segment is arranged at a second radius in relation to the longitudinal axis, and the second radius is different from the first radius; and
wherein the respective radiuses of the segments are gradually changed whereby the segments form a continuous support surface.

Abstract
A vacuum cleaner nozzle having a rotatable member arranged around a longitudinal axis for picking up particles from a surface to be cleaned, and a cleaning arrangement for removing articles entangled on the rotatable member. The cleaning arrangement has at least one support surface provided on at least one radially projecting member of the rotatable member, and at least one cleaning member movable between a resting position in which the cleaning member is arranged at a distance from the support surface and at least one cleaning position in the vicinity of the rotatable member. In the cleaning position, the cleaning member co-operates with at least one segment of the support surface to remove any entangled articles from the rotatable member as the rotatable member rotates. The at least one support surface comprises a number of segments arranged at an individual respective radius in relation to the longitudinal axis.
