Description

(54) IMPROVEMENTS RELATING TO VACUUM CLEANER NOZZLES (71) I, HANS WESSEL, a West Ger man Citizen, of D-5226 Reichshof 31, Wildbergerhutte, West Germany, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed to be particularly described in and by the following statement: This invention relates to vacuum cleaner nozzles.

Vacuum cleaner nozzles are generally equipped with brushes or fibrous elements whose main purpose is to pick up threads.

However, they are not always very effective, and they are prone to wear quickly.

The aim of this invention is to improve this performance, both by choice of material and by positioning in relation to the nozzle.

According to the present invention there is provided a vacuum cleaner nozzle having brush elements on opposite sides of a suc- tion aperture, wherein the elements are housing in recesses with downwardly projecting protective rims in the underside of the nozzle body, and wherein bristles a; the elements project below the rims, incline downwardly and inwardly towards the aperture, and terminate between 2 and 2 5mum above the lowermost points of the nozzle body.

Preferably, the elements are of brush velour, each comprising a base, secured within the associated recess, and said bristles, the overall height of each element being in the range 3 2 to 37mum and the thickness of the base being 1 2mum. Conveniently, each base is a strip of polystyrene. The brush velour may be composed of 55% nylon and 45 /0 cotton at an area density of 400 g/m2.

For a better understanding of the invention, one embodiment thereof will now be described, by way of example, with reference to the accompanying drawing, in which the single Figure is a vertical section through part of the underside of a vacuum cleaner nozzle.

The nozzle has a body shell 1 whose underside is adapted to slide over the surface to be cleaned and which has thread pick-up elements 2 on both sides of a suc- tion aperture 3. The elements 2 are housed in recesses 4 pressed, moulded, or otherwise formed in the shell 1, leaving downwardly projecting rims 5 on either side which prevent premature wear of the elements 2.

Each element 2 comprises a base 6 and bristles 7 projecting downwardly therefrom below the level of the rims 5 but terminating a distance x above the lowermost undersurfaces 8 of the body shell 1. The bristles 7 also incline from their bases 6 inwardly towards the aperture 3. The surfaces 8 flank the aperture 3 and merge into surfaces which incline upwardly to the side walls of the body shell 1.

The overall height of the elements 2 is preferably in the range 3 2 to 3 7mum, with the thickness of the base 6 about 1 2mum and the distance x between 2 and 2 5mum.

The base may be made of polystyrene and the bristles 7 may be provided by a brush velour composed of 55% nylon and 45% cotton at an area density of 400 g/m2.

In use on a carpet the tips of the velour will touch the pile, and as the nozzle is moved to and fro the elements 2 will dislodge dirt and threads. The rush of air past the whole length of the bristles will entrain any lifted dirt and carry it to the aperture 3.

The incline of the bristles 7 means that on each stroke of the nozzle one set is stripping off dirt ready to be easily sucked up on the return stroke.

WHAT I CLAIM IS:--- 1. A vacuum cleaner nozzle having brush elements on opposite sides of a suction aperture, wherein the elements are housed in recesses with downwardly projecting protective rims in the underside of the nozzle body, and wherein bristles of the elements project below the rims, incline downwardly and inwardly towards the aperture, and terminate between 2 and 2 5mum above the lowermost points of the nozzle body.

2. A vacuum cleaner nozzle as claimed in claim 1, wherein the elements are of brush velour
