Cleaning nozzle and method for vacuum cleaning
First Claim
1. A vacuum cleaner nozzle bounding an inlet for guiding aspirated air through the nozzle, the nozzle comprising:
- a rim along an outer end contour of the inlet for contacting a floor surface area when in an operating position on the floor surface, wherein at least a leading rim portion of the rim is movable between (i) a lowered position for contacting a floor surface or extending close to the floor surface, and (ii) a lifted position for leaving a spacing, or at least a larger spacing, between the rim portion and the floor surface, wherein the leading rim portion is hingedly suspended, and wherein the leading rim portion, when in the lifted position, is in a position pivoted inwardly towards the inlet from the lowered position of the leading rim portion; and
a rim operating structure for lifting and lowering, during a movement stroke of the nozzle over the floor surface in a given direction, the leading rim portion between the lowered position and the lifted position;
wherein the rim operating structure is adapted for leaving the leading rim portion in the lowered position during a portion of the movement stroke of the nozzle over the floor surface in the given direction and for subsequently, during a later portion of the movement stroke in the given direction, starting the lifting of the leading rim portion to the lifted position.

Abstract
The invention relates to a vacuum cleaner nozzle (1) bounding an inlet (2) for guiding aspirated air through the nozzle (1). The nozzle (1) comprises a rim (3, 4) along an outer end contour of the inlet (2) for contacting a floor surface area (6) when in an operating position on the floor surface (6), wherein at least a rim portion (3, 4) is movable between a 5 lowered position for contacting a floor surface (6) and a lifted position for leaving a spacing between the rim portion (3, 4) and the floor surface (6). A rim operating structure (21) is adapted for leaving the rim portion (3, 4) in the lowered position during an initial portion of a movement stroke of the nozzle over the floor surface (6) in a direction and for subsequently, during a later portion of the stroke, starting the lifting to the lifted position. This improves the aspiration of larger particles.
