Cleaning nozzle for a vacuum cleaner
First Claim
1. A nozzle for a vacuum cleaner, the nozzle comprising:
- a rotatable member for picking up particles from a surface to be cleaned, the rotatable member being arranged to rotate around a longitudinal axis; and
a cleaning arrangement for removing articles entangled to 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,the at least one support surface comprising a plurality of segments, each of the segments being arranged at an individual radius in relation to the longitudinal axis, wherein the radius of the segments is gradually changed whereby the segments form a continuous support surface,at 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 cleaning member comprises a resilient sheet member capable of providing a resilient contact with at least one segment of the at least one support surface in the at least one cleaning position during rotation of the rotatable member, andwherein the resilient sheet member of the cleaning member in the at least one cleaning position meets tangent of the at least one segment of the at least one support surface at an angle a which is in the range of 40°

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, 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 cleaning position, 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. The cleaning member includes a resilient sheet member capable of providing resilient contact with a segment of the support surface in the cleaning position during rotation of the rotatable member.
