Description

79109737- 4 Det pa ritningen visade sugmunstycket omfattar en kapa 10, ett planmunstycke ll och ett borstmunstycke 12. I planmunstyckets centrala del är väggar anordnade, vilka med sina övre kanter anligger mot kåpan. Väggarna 13 bildar en sugkanal 14, som leder luft från munstyckets sugöppning 15 till dess anslutningsrör 16, som förbinder mun- stycket via en sugledning med en icke visad dammsugare. Borstmunstycket 12 är mot kraften av en fjäder 18 rörligt mellan ett undre läge, arbetslaget, och av fjäderkraft lyftbart till ett övre läge, viloläget. The suction nozzle shown in the drawing comprises a cap 10, a flat nozzle 11 and a brush nozzle 12. In the central part of the flat nozzle, walls are arranged, which with their upper edges abut against the cover. The walls 13 form a suction duct 14, which directs air from the suction opening 15 of the nozzle to its connecting pipe 16, which connects the nozzle via a suction line to a vacuum cleaner (not shown). The brush nozzle 12 is movable against the force of a spring 18 between a lower position, the working stroke, and can be lifted by spring force to an upper position, the rest position.

I sugledningen 17, lämpligen i dess icke visade manöverskaft, medelst vilket sugmunstycket kan föras på arbetsy-tan, är en ventil 19 anordnad med hjälp av vilken sugledningens genomströmningsarea är tillslutbar, såsom visas i fig. l. Mellan mun- styckskàpan 10 och anslutningsröret 16 är ett hölje 2D anordnat inom vilket en klaff 21 är svängbart lagrad medelst ett cylindriskt nav 22. Med navets periferi är en steg- hake 23 förenad med sin ena ände. Dess andra fria ände löper pâ ett steghjul 24, som i sin periferi har fyra utåtriktade utspràng 25. Dessutom är pâ steghjulet 24 utformade två diametralt belägna kamytor 26. En fjäder 27 häller klaffen 21 i det i fig. 1 visade läget, i vilket klaffen tillsluter sugkanalen lll.In the suction line 17, suitably in its control shaft (not shown), by means of which the suction nozzle can be moved on the working surface, a valve 19 is arranged by means of which the flow area of the suction line is closable, as shown in Fig. 1. Between the nozzle housing 10 and the connecting pipe 16 a housing 2D is arranged within which a flap 21 is pivotally mounted by means of a cylindrical hub 22. With the periphery of the hub a step hook 23 is connected to its one end. Its other free end runs on a step wheel 24, which in its periphery has four outwardly directed projections 25. In addition, two diametrically located cam surfaces 26 are formed on the step wheel 24. A spring 27 pours the flap 21 in the position shown in Fig. 1, in which the flap connects the suction duct lll.

'Anordningen fungerar pa följande sätt. När ingen luft strömmar genom sug- munstycket befinner sig ventilen 19 och klaffen 21 i det i fig. 1 visade läget. Klaffen pâverkas av en fjäder 27 till stängningsläget. När ventilen 19 ställes i det i fig. 2 visade läget, vrides. klaffen Zl på grund av det i sugledningen alstrade undertrycket mot fjäderkraft till det i fig. 2 visade läget. Steghaken 23 skjutes mot ett av steghjulets 24 utspràng 25 och steghjulet 24 med sina kamytor vrides därvid 900 moturs. Kamytorna 26 intar det i fig. 2 visade läget och fjädern 18 lyfter borstmunstycket till dess viloläge. En arbetscykel består således av en stängning och en öppning av ventilen 19. Stoppas dammsugarens motorfläktaggregat, återgår klaffen 21 till det i fig. 1 visade läget och för med sig steghaken 23, som hakar in i närmast liggande utsprång.The device operates as follows. When no air flows through the suction nozzle, the valve 19 and the flap 21 are in the position shown in Fig. 1. The flap is actuated by a spring 27 to the closing position. When the valve 19 is set in the position shown in Fig. 2, it is turned. the flap Z1 due to the negative pressure generated in the suction line against spring force to the position shown in Fig. 2. The step hook 23 is pushed against one of the projections 25 of the step wheel 24 and the step wheel 24 with its cam surfaces is thereby rotated 900 clockwise. The cam surfaces 26 assume the position shown in Fig. 2 and the spring 18 lifts the brush nozzle to its rest position. A work cycle thus consists of a closing and an opening of the valve 19. If the vacuum cleaner's motor fan unit is stopped, the flap 21 returns to the position shown in Fig. 1 and carries the step hook 23, which hooks into the nearest projection.

Ventilen 19 är lämpligen anordnad i sugledningens manöverskaft och är manuellt pàverkbar mot verkan av en icke visad fjäder, så att den i sitt ändläge tillsluter sugledningens 17 genomströmningsarea. Själva munstycket kan vara försett med ett organ för visuell indikering av arbetsorganens ll, 12 läge i förhållande till arbetsytan.The valve 19 is suitably arranged in the operating shaft of the suction line and is manually actuated against the action of a spring (not shown), so that in its end position it closes the flow area of the suction line 17. The nozzle itself may be provided with a means for visually indicating the position of the working means 11, 12 in relation to the working surface.

En fördel med anordningen enligt föreliggande uppfinning är att växlingen av munstyckets arbetsorgan kan ske manuellt från manöverskaftet utan besvärliga kraft- överföringsanordningar av typ vajrar, slangar osv. Anordningen har dessutom servo- verkan, dvs. manöverkraften är avsevärt mindre än för en direktmanövrerad växlings- mekanism.An advantage of the device according to the present invention is that the working means of the nozzle can be changed manually from the control shaft without cumbersome power transmission devices such as wires, hoses, etc. The device also has a servo effect, ie. the operating power is considerably less than for a directly operated shift mechanism.
