NL8001789A - Vacuum cleaner nozzle mounting - has elastic components in top most part bearing against parallel pivot axes - Google Patents

Abstract

The vacuum cleaner nozzle has a union and a sliding shoe tilting about an axis at right angles to the reciprocating movement of the nozzle in use, so that within a defined angle it always lies flat on the surface to be cleaned. Inside the topmost part (1) of the nozzle are elastic components (10) which, when it is fitted to the lowermost part, bear against the pivot axis of the shoe (4) and also against a hinge axis (6) parallel to it. The latter axis is one part of two hinging together forming a connector hinging up and down, and for coupling to the suction pipe.

Vacuum cleaner nozzle.

The invention relates to a vacuum cleaner nozzle of the type, which is provided with a connecting element and a sliding sole, which during tilting back and forth during use can be tilted about an axis transverse to this direction of movement, such that it is always within a certain pivoting range. has a flat support on the surface to be cleaned.

'Ψ 4

A vacuum cleaner nozzle according to this prior art is known from the D.O.S. 2.36 ^ -. 750.

10 '- When using vacuum cleaner nozzles, lying flat on the surface of the sliding sole to be cleaned is a necessary condition. maximum effect when vacuuming and for picking up threads. A further important requirement is the lowest possible construction of the suction nozzles, in order to ensure that they can be moved far below furniture or the like for cleaning.

However, this is not the case with the hitherto known nozzles to the desired degree, even when, as disclosed in U.S. Pat. No. 3,815,170, they have been previously described. . see a turn-tilt hinge. This known hinge is n.1. installed in the housing in such a way that no essential reduction of the construction height is achieved.

The object of the invention is now a vacuum cleaner nozzle of the above-mentioned type, which can be manufactured rationally and with which, at minimum construction height, without significant change of position of the user, e.g. it is possible for a housewife to work around furniture pieces as well as underneath with a maximum surface on the surface to be cleaned.

This object is achieved with a vacuum cleaner nozzle of the type mentioned in the preamble, in that, according to the invention, elastic lying elements are arranged on the inside of the nozzle top part, which, when the nozzle tip is joined together with the bottom nozzle part, on the tilting axis. of the sliding sole and on a parallel to this tilting axis - 8001789 i ·.

2 the pivot axis take up its position, the latter part of which the connecting element consisting of two parts which are rotatably connected to each other is pivotally mounted in height, while the other part thereof serves to connect to a suction pipe.

Further measures according to the invention, which form further elaborations of the inventive idea, are stated in the subclaims 2 to J.

The invention will now be further elucidated with reference to the drawing, which shows an embodiment according to the invention solely by way of example for the invention.

Fig. .1 is a longitudinal section of a vacuum cleaner nozzle according to the invention; Fig. 2 is a cross-sectional view taken on the line II-II 15 of Fig. 1 of the suction channel and. the connecting element; Fig. 3 is a cross section taken on the line III-III in Fig. 2 with the mooring elements; Fig. Ij is a longitudinal section taken on the line IV-IV in Fig. 3 of the upper nozzle part and the lower nozzle part 20 together with the mooring elements.

The invented vacuum cleaner nozzle essentially exists. from a top nozzle part 1, a bottom nozzle part 2, a sliding sole h pivotable about a tilting axis 3, a suction channel 5 with a pivot axis. 6 for alloying the connecting element 7 and finally 25 'rollers 8.

The connection between upper nozzle part 1 and lower nozzle part 2 is established by mooring elements 9, which occupy a lying position on the tilting shaft 3, which is mounted in the lower nozzle part 2. For further attachment, the pivot shaft 6, which acts in the suction channel 5 is arranged and runs parallel to the tilting axis 3, the suction channel 5 being hingedly mounted on the tilting axis 3. The upper nozzle part 1 is also mounted on the pivot axis 6 by means of mooring elements 10.

The mooring elements 9, 10 are designed as thin-walled, open-spreading and retaining tabs 11 to be fitted, the spreading of the mooring elements through slots 12 in the extension.

3 of the berth zone 13 is ensured. To facilitate snapping, chamfers 1U are formed on the retaining lips 11.

In order to simplify the construction of the molds, the top nozzle part 1 and the suction channel 5 are made in two parts, after mounting via the shafts 3 and 6 as well as the mooring elements 9 and 10, which pass through the suction channel 5 and the mooring elements 9 and 10.

The sliding sole is also rigidly connected via fastening elements 15 to the lower nozzle part 2. The sliding sole 3, which is mounted in the lower mouthpiece part 2 and via the mooring elements 9 »10 in the upper mouthpiece part 1, allows the sliding sole to join together, with the lower mouthpiece part 2 in the upper mouthpiece part. 1 can be swirled over a book α. Abutment lips formed in the upper nozzle part serve as tilt limit. To avoid; of suction of false air, the connection opening 17 of the bottom nozzle part 2 engages the suction channel opening 18 of the suction channel 5.

At the rear end of the suction nozzle 5 leaving the suction channel 5 at the rear side of the suction channel 5, the connecting element 7 is pivotally mounted in height. The one part 2Q of the connecting element 7 is also mounted in the suction channel 5 in a breech-like manner, in order to ensure that the swivel weighing in height direction to avoid the supply of wrong or false air. The pivotal weighing is limited in this range by the stop 21 and by the shape of the suction channel 5. The second part 22 of the connecting element 7 is rotatably mounted in the part 20 and serves to connect to a suction pipe 23.

In order to ensure good movability of the suction nozzle 30. and to avoid excessive pressure on the tilting sole 1+ are attached to the suction channel 5 on both sides, outside, the running rollers 8 already mentioned ... These, like the connecting element 7, are attached to the pivot shaft 6 and are berth elements 10, which are in this range. hold the upper nozzle part 1, fixed in the bun position.

Fixing the position of the tilting axis 3 and of the pivoting axis 6 on the inside of the upper nozzle part 1 8001789 4 τ! + Molded lips 2h and 25 serve. In the area of the track rollers alloy, nose profile rings 26 formed on the suction channel 5 are provided, which engage in corresponding receptacles 27 in the "upper nozzle part 1 for additional fixing of the position of the suction channel to the side. 5 with respect to the upper nozzle part 1.
