Description

A VACUUM CLEANER MOUTHPIECE
The present invention relates to a vacuum cleaner nozzle for cleaning of carpets and smooth surfaces and of the type described in the introductory part of claim 1.
Froia DE-A1 23 30 867 a combination nozzle of this type is known, that is with wheel, and where one single brush mem¬ ber by means of a foot operated shift mechanism may be rai¬ sed and lowered in relation to a fixed suction sole.
The invention has for its purpose to provide a nozzle of the type described in the introductory part, and by which by simple provisions an improved useful effect may be ob¬ tained.
The vacuum cleaner nozzle according to the invention is di¬ stinctive in that upper edge parts of the suction sole has a such inclined pass, that the brush holder plate, when lo¬ wered and pressed against said upper edge part of the suc- tion sole, is also inclined in such a manner, that the brushes along the whole circumference and the stationary wheels at the same time may rest against the cleaning sur¬ face, and that the brush holder plate at its underside is provided with tightening means being adapted to cooperate with said upper edge parts of the suction sole, so that it may close totally tight to the brush holder plate. By simp¬ le provisions a strong improved useful effect is obtained that the brushes at the whole circumference of the brush holder plate - at the same time as the nozzle still is sup- ported by said wheel - may rest against the cleaning surfa¬ ce, as the whole hood-shaped housing by lowering of the brush holder plate against said upper inclined edge parts of the suction sole will take up a corresponding backwards/ downwards inclined position in relation to the wheels.
UBSTITUTE SHEET In order to improve the useful effect of the vacuum clea¬ ner nozzle further, expediently it may be provided so that the brush holder plate at its the underside is provided with tightening means, being adapted to cooperate with said upper edge parts of the suction sole, so that it may shut totally tight to the brush holder plate. Hereby by simple provisions a possibility to counteract, that parts of the housing above the brush holder plate are exposed to false air and eventually soiled, so that the function of the shift pedals is affected, which is an ordinary problem by known vacuum cleaner nozzles of the said kind, where it from time to time is necessary to dismount the suction sole in order to maintain the shift mechanism by cleaning the nozzle.
Preferably said tightening means at the underside of the brush holder plate are placed just inside the brushes and preferably stretching along the whole circumference of the brush holder plate.
In the following the invention is described in more details with reference to the drawing, in which:
Fig. 1 shows a view - partly in section through the shift mechanism - of an embodiment for a vacuum cleaner nozzle according to the invention.
Fig. 2 shows a side view - partly in section through the shift mechanism - of a vacuum cleaner nozzle according to the invention - shown with the brush holder plate in its raised inactive position,
Fig. 3 shows a side view - partly in section - of a vacuum cleaner nozzle according to the invention - shown with the brush holder plate in its lowered active position, and Fig. 4 shows a side sectional view through the middle of a vacuum cleaner nozzle according to the invention - shown with the brush holder plate in its raised inactive posi¬ tion.
The vacuum cleaner nozzle shown in Fig. 1 comprises a hood- shaped housing 4 with a central cavity 6 for a tiltable ar¬ ranged connecting part 7 around a common wheel axle 5 and a pivotable connecting piece 8 and a suction sole 10, which by means of a integrated rectangular tube 11 fitting tight inside a corresponding rectangular tube 13 provided as a part of the housing 4, is connected with the cavity 6, and secured to the housing by screws 12, for instance being placed in vertical supports 14, which lead through circular openings in a displaceable brush holder plate 16 with brus¬ hes 18, said brush holder plate being adapted to be raised and lowered around the suction sole 10 between a raised in¬ active position (Fig. 2) and a lowered active position (Fig. 3).
Springs 15 are mounted between the housing 4 and the brush holder plate 16, and these springs are placed around the supports 14 at opposite ends of the nozzle 2 and the brush holder plate 16, respectively, and affect the latter with a permanent downwards directed spring effect. The suction so¬ le 10, which as mentioned is secured to the supports 14, are also supported at the bottom of the housing 4 by fur¬ ther supports 22, lower ends of which are resting against the upperside of the suction sole 10 on level with longitu- dinal suction channels 24 being connected with the central cavity 6.
The vacuum cleaner nozzle 2 is provided with a shift mecha¬ nism for the brush holder plate 16, which in a known manner is operated by cooperating foot pedals 26, 28 being connec¬ ted with an along the housing arranged common crank-like axle 30. The latter is provided with projecting swing arms 32 at opposite ends of the nozzle, which arms 37 in a di¬ stance from the axle 30 are provided with a two-sided pro¬ jecting activation members in form of a cylindrical cross- beam 34 adapted to engage with arched underside members 36 of separate lifting arms 38 as shown. These arms 38 are at an end provided with a transverse, cylindrical bearing mem¬ ber 40, which is pivotally arranged between bearing console members 42 inside the housing 4. The lifting arms 38 are two-sided, as the bearing member 40 just inside the opposi¬ te end parts 44 has two arm parts 46, which with mutual di¬ stance are stretching inwards towards the middle of the nozzle 2, as the arm parts 46 via opposite offsets 48 con¬ tinue inwards with less mutual distance to a transverse end part 50 projecting to both sides of the arm parts 46. These are at undersides 52 from the offsets 48 and some distance towards the end parts 50 provided with downwards/outwards arched engagement surfaces 54 against which the crossbeams 34 of the swing arms 32 are adapted to be guided for rai- sing and lowering the lifting arms 38, respectively, as the crossbeams of the swing arms are adapted to be inserted between the arm parts 46 behind the offsets 48 for coopera¬ tion with the arched engagement surfaces 54 thereof in front of the offsets 48, where the mutual distance between the arm parts 46 is adjusted to the width of the swing arms 32 within the crossbeams 34.
The swing arms 32 are in a distance within the crossbeams 34 provided with a therefrom projecting arm 60 at the same level as the swing arm 32, which arm 60 with an end part 62 is adapted to form an upper stop for the brush holder plate 16, that is in practice for the transverse end parts 50 of the lifting arms 38, when the brush holder plate 16 takes up its lowered active position (Fig. 3) , where the cross- beams 34 of the swing arms 32 do not engage with the arched engagement surfaces 54 of the lifting arms 38, as the swing arms 32 by means of a spring device 25, which affects the crank-like axle 30 against one of the two possible outer positions (A and B, Fig. 4) , is fixed in a such position.
At the backside of the hood-shaped housing 4 a wheel 66 is placed in a housing part 64, which serves to support the nozzle 2 in the shown situations of use (Fig. 2 and 3) . The brush holder plate 16 is just inside the brushes 18 provi¬ ded with a surrounding tightening member 68 with a projec- ting tightening lip 70. The suction sole 10 is at its top side, that is at the side facing the brush holder plate 16, provided with an inclined pass in such a manner, preferably by a integrated edge member of plastic 72, that the suction sole 10 has the maximum height closest at the wheels 66, and that the suction sole 10 in principle is placed perma¬ nently in the housing 4, that upper edge parts 72 of the suction sole 10 may cooperate with the tightening member 68 inside its tightening lip 70, when the brush holder plate 16 is allowed to be lowered against the upper edge parts 72 of the suction sole 10, so that this may close tightly to the brush holder plate 16.
