There are many various types of nozzles, each for a special purpose. Floor nozzles, furniture nozzles and nozzles for cleaning radiators may be mentioned. Almost all manufactures have their own version of the basic types.

However, there has been noticed a lack of a nozzle for vacuuming under low furni- ture on the market. Among present furniture there are many pieces of furniture in use under which can not be reached with a usual crevice nozzle. However, that type of a nozzle is just the one, which is used to finish the work while there is not a bet- ter one available. Vacuuming by means of a nozzle like this is difficult also be- cause the handle of the hose or of the extension tube of a vacuum cleaner appears to be close to the floor, which means bowing close to the floor. It is difficult and even risky especially for aged people and people in poor health to bow like that. Fur- thermore, the suction opening in the earlier mentioned nozzle is placed, as com- monly known, in the outer end of the nozzle. Therefor vacuuming under furniture is difficult even in places, which the nozzle reaches. The result very easily remains poor. Loose dust is easy to remove, but powdery dust on the floor is removed only there where the peak of the nozzle has touch the floor.

The purpose of the invention is to provide a nozzle, by using of which the earlier presented disadvantages are eliminated. Especially, the purpose of the invention is to provide a nozzle, which besides this may be used as a floor nozzle on smooth floors and on carpets.

The object of the invention is accomplished by a nozzle, the characteristics of which are presented in the claims.

Suction openings in the nozzle in accordance with the invention are placed on the long side of the suction head, which is meant to be pointed against the surface to be cleaned. The nozzle in accordance with the invention eliminates mentioned disad- vantages. Furthermore, it may successfully be used as a floor nozzle on smooth floors and on carpets. Vacuuming is done very well also under other furniture not only under low furniture by means of this nozzle. For example, vacuuming between

legs of a chair under a table is done very handy by means of the nozzle in accor- dance with the invention. Handling erconomics, which reminds of sweeping with an ordinary brush rather than toiling reminding of pushing in front of your, as work- ing with present nozzles, has surely its part in this. There are certain similarities in handling the new nozzle with the handling of an ice-hockey stick and therefor it is possible to get young men in families interested in vacuuming.

Next, the invention will be explained in more detail with reference to the accompa- nying drawings. In these applications the nozzle has been planned to be manufac- tured mainly of thermoplastic by injection moulding or blow moulding.

Figure 1 illustrates a nozzle in accordance with the invention viewed from below that is from the suction surface and side, Figure 2 illustrates a different kind of suction surface construction viewed from be- low, Figure 3 illustrates another kind of suction surface construction viewed from below, Figure 4 illustrates a variant to manufacture the angle part with a joint viewed from side, Figure 5 illustrates to manufacture the angle part with a flexible folded part viewed from side, and Figure 6 illustrates how to connect the angle part and the suction head pivotedly viewed from side.

In all figures the nozzle S includes the suction head 1, which is moved along the ob- ject to be vacuumed, the angle part 2, by means of which it is possible to do the vacuuming in standing position, and the attaching part 3, to which the hose or a stiff tube of a vacuum cleaner is connected (these are not illustrated in figures).

In figure 1 there is a suction crevice 4 almost as long as the suction head in the suc- tion head 1, through which the dust from the place to be vacuumed is removed through the angle part 2 and the attaching part 3 to a hose connected to it. In this version the flow bosses 5 are made of acid-proof steel wires, which have been placed crosswise in regard to the suction crevice 4, over it, advantageously at few centimetres intervals. The meaning of the flow bosses 5 is to let enough air to flow into the nozzle S, such that the dust may also move. The suction head 1 is formed

with rounded corners, thus the risk to damage the furniture essentially decreases.

For the same goal serves the lightness of the nozzle S.

The length of the suction head 1 is advantageously 40-60 cm, such that vacuuming under an ordinary bookcase is remarkable easy, but the length is however being within reasonable limits being handy to use. It is easy to vacuum bigger pieces of furniture, such as desks from two sides to the half way. Vacuuming of a smooth floor is carried out by sweeping with natural crosswise curved move. Vacuuming under tables with present nozzles is difficult, but the nozzle S in accordance with this invention is easy to pass between legs of chairs and tables, and even chairs must not necessary be removed.

The inclination of the angle part 2 and the floor, or the surface in general to be vac- uumed is advantageously 45 °. Very upright position decreases the effect of vac- uuming, because in that case the person doing the vacuuming is also in relatively upright, taut position. A small angle, essentially less than 45 °, on the other hand, makes the person doing the vacuuming to bow while working, which strains the back.

The attaching part 3 is planned to be such, that it is suitable with hoses of as many various vacuum cleaners as possible. On the other hand, if the product is manufac- tured for a special mark of vacuum cleaner, the suitability for especially that type is secured to be the best possible.

In figure 2 there is a variant to manufacture the flow bosses. This variant includes some bosses 5a made to the plastic suction head. The advantage of this solution is the economical manufacture, because the bosses are made of the same material without special working phase. The functional construction does not differ from the earlier mentioned.

In figure 3 there is still another solution for the construction of the suction surface of the nozzle S. It includes advantageously part 6 made of fine steel plate, in which openings 4b are made for suction crevices and bosses 5b for flow bosses. In this so- lution excellent durability and reasonable economical manufacture are combined.

Figure 4 presents the angle part 2 with a joint 7. Although the stiff angle part in ac- cordance with the figure 1 is enough in many cases, some advantages may be gained by modifiability of the angle part. The angle part 2 comprises the joint 7 connecting turnable the suction head 1 and the attaching part 3. The joint includes advantageously a tightening mechanism 8, for example, a tension screw, the tension

nut 8a of which is presented in figure. The tightening mechanism may be used to regulate the turning resistance of the joint. The joint 7 gives the user the possibility to choose the wanted angle between the suction head 1 and the attaching part 3 even by phases of work.

Figure 5 illustrates the connection of the angle part 2 and the attaching part 3 by means of a flexible bellows 9. Simply turning the attaching part 3 with the suction tube of the vacuum cleaner (not illustrated) may carry out the change of the angle of it while working. The regulation of this version is superior quick and a natural measure in comparison with the regulation of the version with the joint 7, althought the accuracy of regulation of the one with a joint is better.

Yet figure 6 illustrates the connection 10 of the angle part 2 to the suction head 1, which has been constructed such, that it makes it possible to turn the suction head 1 round its longitudinal axis in regard to the angle part 2. The connection 10 in itself is, by technique, a usual male-female-connection with a groove in one part and suit- able to it nails in the other part. This enables to vacuum also under a double bed by means of the nozzle in accordance with the invention, as the tube of the vacuum cleaner functions as an extension of the nozzle S on the same level. However, one has to bow as earlier while vacuuming under beds. Turning the suction head 1 makes many asymmetric working phases easier, for example vacuuming of walls.

Besides earlier mentioned examples of construction also commonly used brush parts in nozzles, made advantageously of bristle and/or of rough plush-like cloth, may be connected to the nozzle of a vacuum cleaner. Also many other variations, versions and development results are possible within the frames of the idea of the invention formed in the claims.
