Description
8106487-5 väggen 18 och med sina motsatta fria ändar 23, 24 löper i slitsar 25, 26 utformade i yttre väggar 19, 20. Slitsarna 25, 26 har formen av kvartscirkelsegment, som är radiellt förskjutna 900 i förhållande till varandra. Motsvarande slitsar 25', 26' är utformade i munstyckets 10 gavlar 15, 16 så att slitsarna 25, 25' och 26, 26' parvis sammanfaller. 8106487-5 the wall 18 and with its opposite free ends 23, 24 run in slots 25, 26 formed in outer walls 19, 20. The slots 25, 26 have the shape of quartz circle segments which are radially offset 900 relative to each other. Corresponding slots 25 ', 26' are formed in the ends 15, 16 of the nozzle 10 so that the slots 25, 25 'and 26, 26' coincide in pairs.
Kroppen -14 är i huvudsak indelad i tre sektorer, av vilka den första sektorn 27 uppbär en borste 28 eller alternativt en remsa av textilmaterial för användning på hårda golv. På varje sida av sektorn 27 är anordnad en sektor 29 och 30 vilka består av släta ytor och vilkas övergångskanter 31 till sektorn 27 användes på mjuka mattor. Fjä- dern 2l, 22 är så dimensionerad att kroppen 14 vrider sig först när rörelsemotståndet vid munstyckets rörelse på mattan överstiger ett visst på förhand inställt värde, exempelvis 2,5 kg. För att undvika luftläckage tätas kroppen med en icke visad gummiduk eller liknande mot munstyckshöljet 13. 'Anordningen fungerar på följande sätt.The body -14 is essentially divided into three sectors, of which the first sector 27 carries a brush 28 or alternatively a strip of textile material for use on hard floor. Arranged on each side of the sector 27 is a sector 29 and 30 which consist of smooth surfaces and the transition edges 31 of which to the sector 27 are used on soft carpets. Fjä- The gate 21, 22 is so dimensioned that the body 14 only rotates when the resistance to movement when the nozzle moves on the mat exceeds a certain preset value, for example 2.5 kg. To avoid air leakage, seal the body with a not shown rubber cloth or the like against the nozzle housing 13. The device operates on the following way.
På hårda golv är rörelsemotståndet vid munstyckets rörelse litet och understiger den inställda kraften av exempelvis 2,5 kg hos fjädrarna 21, 22. Kroppen 14 intar det i fig. 2 visade läget, dvs. borsten 28 eller ramsan ligger an mot den hårda arbetsytan och avlägsnar, medelst det i sugkanalen och sugöppningen 12 alstrade undertrycket, på ytan befintligt damm, trådar och dylikt.On hard floors, the movement resistance of the nozzle movement is small and less than the set force of, for example, 2.5 kg of the springs 21, 22. The body 14 absorbs it in Fig. 2 showed the position, i.e. the brush 28 or the frame abuts the hard work surface and removes, by means of the negative pressure generated in the suction channel and the suction opening 12, on the surface existing dust, wires and the like.
Vid munstyckets rörelse på en matta i den i fig. 3 visade riktningen, dvs. från användaren, befinner sig fjädrarnas 21, 22 fria ändar 23, 24 i slitsarnas 25, 26 översta punkter, 'såsom framgår av fig. 1 och 2, dvs. fjädern 21 spännes av rörelsemotståndet mellan borsten och underlaget vid munstyckets rörelse. Fjäderns 22 fria ände 24 löper då i slitsen 26 respektive 26' från sitt översta, förspända läge till det i fig. 3 visade ändläget ochövergångskanten 31 mellan den släta sektorn 29 och sektorn 27 löper på mattan. Borsten 28 är därvid ej i kontakt med mattan.When the nozzle moves on a mat in the direction shown in Fig. 3, i.e. from user, the free ends 23, 24 of the springs 21, 22 are located at the top of the slots 25, 26 points, 'as shown in Figs. 1 and 2, i.e. the spring 21 is tensioned by the resistance of movement between the brush and the base during movement of the nozzle. The free end 24 of the spring 22 runs then in the slot 26 and 26 ', respectively, from their uppermost, biased position to that shown in Fig. 3 the end position and the transition edge 31 between the smooth sector 29 and the sector 27 run on mattan. The brush 28 is then not in contact with the carpet.
Föres munstycket 10 i motsatt riktning, dvs. mot användaren, återföres krop- pen l4 av fjäderns Zl under föregående rörelse alstrade kraft till det i fig. 2 visade läget. Den fria fjäder-änden 24 befinner sig nu i slitsens 26 högsta punkt och rörelse- motståndet övervinner fjäderns 22 kraft och vrider kroppen 14 till det läge som visas i fig. 4. Övergångskanten 31 mellan sektorn 27 och den släta sektorn 30 löper nu på mattan. Under arbetets gång vrides sålunda kroppen 14 av rörelsemotståndet som överstiger fjäderkraften och intar växelvis det i fig. 3 respektive fig. 4 visade läget.Move the nozzle 10 in the opposite direction, ie. against the user, the body is returned pin 14 of the spring Z1 during the previous movement generated force to that shown in Fig. 2 the situation. The free spring end 24 is now at the highest point of the slot 26 and the movement the resistor overcomes the force of the spring 22 and rotates the body 14 to the position shown in Fig. 4. The transition edge 31 between the sector 27 and the smooth sector 30 now runs on mattan. Thus, during the course of the work, the body 14 is rotated by the motion resistance which exceeds the spring force and alternately assumes the position shown in Fig. 3 and Fig. 4, respectively.
Uppfinningen är icke begränsad till den visade utföringsformen utan kan varieras inom ramen för efterföljande patentkrav. Det är t.ex. möjligt att applicera en vridbar kant i ett munstycke som innehåller en i sugöppningen roterande borstvals. I sådant fall anordnas en vridbar kant på sugöppningens bakre del, dvs. i riktning mot användaren, för att undvika att smutspartiklar slungas ut av borstvalsen.The invention is not limited to the embodiment shown but can be varied within the scope of the appended claims. It is e.g. possible to apply a rotatable edge of a nozzle which contains a brush roller rotating in the suction opening. In that case a rotatable edge is arranged on the rear part of the suction opening, i.e. in the direction of the user, for to prevent dirt particles from being thrown out of the brush roller.
