Abstract

A B S T R A C T

A vacuum cleaner nozzle comprises a housing (10) having first and second air inlets (13,15) adapted to different cleaning duties. Each of the inlets is connected to a respective outlet (17,19) via a separate duct (16,18).
The outlets are arranged on different sides of the housing and are separated by a partition (20) to form two independent sockets for a tube handle con-nected to a vacuum source.

Description

63939-1~0 The present inven~ion relates to a vacuum cleaner nozzle, comprislng a housing having first and second air inlets adapted to different cleaning purposes, the first alr inlet belng connected to a first air outlet via a first duct and the second air inlet being connected to a second air outlet via a second duct.
Nozzles of the above--mentioned type, so-called combination nozzles, are previously known and are used e.g. for cleanlng of upholstered as well as hard furniture, shelves, pictures, and so on. These nozzles are relatively small in order to facilitate handling and accessibility. They have a first air inlet opening surrounded by a brush for cleaniny of hard surfaces, and a second air inlet opening surrounded by hard edges to be used on soft material. In one such type o~ a nozzle the two openings are arranged opposite to each other, and when air and dust are flowing in through one opening the other opening is serving as a holder for a tube handle belonging ~o the vacuum cleaner, and vice versa. The tube handle is in turn in connection with a fan assembly via a dusk hag. One of the openings is enlarged by folding out two nozzle portions. One disadvantage of this type of nozzle is that it comprises movable portions which complicates the manufacture of the nozzle.
In a similar type of combination nozzle having ~wo separate air inlets, ~he two outlets have such a mutual disposition tha~ the tube handle blocks one outlet while communicating with the other, and vice versa. A disadvantage of this arrangement is that the portion of the nozzle to whlch the '~

63g39-130 tube handle is connected must be made with high preclsion since otherwise leakage might occur, or difficulties ln fitting and keeping the tuhe handle in the nozzle.
The pre~ent inventlon provides a vacuum cleaner nozzle comprising a generally rectangulax housing having first and second air inlets adapted to different cleaning purpo es, the first alr inlet being connected to a ~irst air outlet via a first duct, and the second air inlet beiny connected to a second air outlet via a second duct, characterized in tha~ the outle~s are arranged on different sides of the housing and separated by a partition, said outlets forming two mutually independent socke~s for a tube handle connected to a vacuum source.
An embodiment of the invention will now be described with reference to the accompanying drawing, in which Figure 1 is a partially cut-away perspective view of a nozzle according to the invention, Figure 2 is a bottom plan view of the nozzle shown in Figure 1, Figure 3 is a longitudinal section of the nozzle along line III-III in Figure 4, and Figure 4 is a section along line IV-IV in Figure 3.
As appears from the Figures the nozzle comprises a housing 10 having a generally '`' ~9 box-like configuration. The housing is preferably of plastic and is made in one piece. The upper rim 11 o-f the housing 10 is inclined upwards and backwards in Fig. 1 and has a brush strip 12 surrounding a first air inlet opening of the nozzle. The lower rim of the housing is designated 14 and is disposed in one and the same horisontal plane, thereby forming a second air inlet opening lS.
The first inlet opening 13 is connected to a first outlet opening 17 via a firstduct 16, and the second inlet opening 15 is connected to a second outlet opening 19 via a second duct 18. The two ducts are separated by a sealing partition 20 which divides the nozzle into two separate halves. The second duct 18 is provided with a central vertical wall portion 21 having a through opening 2'~ disposed opposite to the outlet opening 19. The lower portion of wall 21 forms a surface 23 which is generally in the same plane as the rim 14 of the nozzle and is covered with a material having bristles extending therefrom and intended to pick up threads and hairs and the like during the cleaning operation, such objects being difficult ~o take up by pL~rs- suction action.

Claims (5)

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A vacuum cleaner nozzle comprising a generally rectangular housing having first and second air inlets adapted to different cleaning purposes, the first air inlet being connected to a first air outlet via a first duct, and the second air inlet being connected to a second air outlet via a second duct, characterized in that the outlets are arranged on different sides of the housing and separated by a partition, said outlets forming two mutually independent sockets for a tube handle connected to a vacuum source.

2. Nozzle according to claim 1, characterized in that the first air inlet is surrounded by a brush and that the second air inlet is encircled by a plane, hard rim portion.

3. Nozzle according to claim 2, characterized in that the second air inlet has a surface provided with a material for picking up threads and the like, said surface being situated inside the rim portion and on the same level as this.

4. Nozzle according to any of claims 1-3, characterized in that the air inlets are generally rectangular.

5. Nozzle according to any of claims 1-3, characterized in that the housing is a one-piece element made of plastic material.
