Abstract
Description
520 zgv medger att hjularrangemanget kan placeras framför dammsugarhöljet varvid ett större fronthjul kan användas utan att det inkräktar på utrymmet i dammsugarhöljet. Detta ernås medelst en anordning som erhållit de i patentkraven angivna kännetecknen. 520 zgv allows the wheel arrangement to be placed in front of the vacuum cleaner housing, whereby a larger front wheel can be used without encroaching on the space in the vacuum cleaner housing. This is achieved by means of a device which has obtained the features stated in the claims.
Två iitföringsexempel kommer nu att beskrivas med hänvisning till bifogade ritningar på vilka fig. i schematisk visar en sidovy av en första utföringsforrn av en dammsugare försedd med en anordning enligt uppfinningen under det att fig 2 i en sprängskiss visar en andra utföringsforni av en dammsugare försedd med anordningen enligt uppfinningen.Two exemplary embodiments will now be described with reference to the accompanying drawings in which fi g. in schematic shows a side view of a first embodiment of a vacuum cleaner provided with a device according to the invention, while fi g 2 in an exploded view shows a second embodiment of a vacuum cleaner provided with the device according to the invention.
Såsom framgår av fig. 1 innefattar dammsugaren ett hölje 10 som uppbärs av ett par bakhjul 11 och ett främre, centralt placerat fronthjul 12. Höljet innesluter på konventionellt sätt en icke visad vakuumkälla i form av ett motorfläktaggregat vars inloppsida står i förbindelse med en slang 13. Slangen är på sedvanligt sätt kopplad till ett icke visat rörskaft som uppbär ett munstycke genom vilket dammbemängd luft är avsedd att upptas från underlaget och transporteras genom rörskaftet och slangen till ett i höljet befintligt, icke visat separationssystem där dammpartiklama avskiljs från den till fläkten strömmande, renade luften.As can be seen from Fig. 1, the vacuum cleaner comprises a housing 10 supported by a pair of rear wheels 11 and a front, centrally located front wheel 12. The housing conventionally encloses a vacuum source (not shown) in the form of a motor kt power unit whose inlet side communicates with a hose 13 . purified the air.
Slangens 13 ände utgör en slangförbindelse 14 som är ansluten till en slangkoppling 15 avsedd att förbinda slangen med ett i höljet fast eller vridbart anordnat knärör 16 varvid knäröret leder den dammbemängda luften in till separationsystemet i dammsugarens hölje.The end of the hose 13 constitutes a hose connection 14 which is connected to a hose coupling 15 intended to connect the hose to a knee tube 16 fixedly or rotatably arranged in the housing, the knee tube leading the dust-laden air into the separation system in the vacuum cleaner housing.
Fronthjulet 12 roterar runt en horisontell hjulaxel 16 som är infäst i en bygel 17 varvid bygeln uppvisar en vertikalt orienterad axel 18 som sträcker sig genom fronthjulets rotationscentrum och är upphängd för vridning i ett par lagringspunkter 19 anordnade i höljet. Vridningsaxelns 18 övre ände är fixerad till en slanghållare 20 som utgörs av en från vridningsaxeln framskjutande, i tvärsnitt huvudsakligen C-fonnad hylsa, företrädesvis av elastiskt material. Hylsans axellinje är horisontellt orienterad och normalt riktad i dammsugarens framföringsriktning och hylsan är så utformad att slangen 13 enkelt kan avlägsnas från slanghållaren genom att slangen utdrages i sidled genom hylsans längsgående öppning.The front wheel 12 rotates about a horizontal wheel axis 16 which is attached to a bracket 17, the bracket having a vertically oriented shaft 18 which extends through the center of rotation of the front wheel and is suspended for rotation in a pair of bearing points 19 arranged in the housing. The upper end of the axis of rotation 18 is fixed to a hose holder 20 which consists of a sleeve projecting from the axis of rotation, substantially in cross-section, mainly of C-shaped material, preferably of elastic material. The shaft line of the sleeve is horizontally oriented and normally directed in the direction of travel of the vacuum cleaner and the sleeve is designed so that the hose 13 can be easily removed from the hose holder by the hose being pulled out laterally through the longitudinal opening of the sleeve.
Den i fig. 1 visade anordningen fungerar på följande sätt. Vid dammsugarens användning är slangen ansluten till knäröret 16 medelst slangkopplingen 15 samtidigt som slangen är införd i slanghållaren 20. När dammsugaren framdrages över underlaget kommer slangen att påverka slanghållaren så att slanghållaren 20 och därmed fronthjulet 12 vrids i den riktning handhavaren rör sig. Då den mellan 520 ga? slanghållaren 20 och slangkopplingen 15 befintliga slangförbindelsen 14 samtidigt fungerar som ett elastiskt element förhindras att stora riktningsändringar av dragkraften i slangen påverkar dammsugaren så att den välter eller fastnar i möbler, dörrposter osv. Man får med andra ord en betydligt bättre följsamhet hos dammsugaren.The device shown in Fig. 1 operates in the following manner. When using the vacuum cleaner, the hose is connected to the knee tube 16 by means of the hose coupling 15 at the same time as the hose is inserted into the hose holder 20. When the vacuum cleaner is pulled over the base, the hose will actuate the hose holder 20 and thus the front wheel 12. Then the one between 520 ga? the hose holder 20 and the hose coupling 15 existing hose connection 14 simultaneously acts as an elastic element, it is prevented that large changes of direction of the traction force in the hose affect the vacuum cleaner so that it overturns or gets stuck in furniture, door posts, etc. In other words, you get a much better compliance with the vacuum cleaner.
Den i fig 2 visade dammsugaren skiljer sig från den i fig 1 visade dammsugaren genom att den uppvisar ett framåtriktat inlopp 21 för den dammbemängda luften varvid inloppet medelst en anslutningsring 22 och en separat, elastisk slanganslutning 23 är kopplad till en slanghållare 24 som i detta fall innefattar en hylsa 25 med en bygel 26 som medelst en axel 27 uppbär fronthjulet 12.The vacuum cleaner shown in Fig. 2 differs from the vacuum cleaner shown in Fig. 1 in that it has a forward-facing inlet 21 for the dust-laden air, the inlet being connected by means of a connecting ring 22 and a separate, elastic hose connection 23 to a hose holder 24 which in this case comprises a sleeve 25 with a bracket 26 which by means of a shaft 27 supports the front wheel 12.
Slanghållaren 24 är vridbart anordnad runt en vertikal axel 28 som bildas av på slanghållarens 24 över- och undersida anordnade axeltappar som är infäst i en övre (ej visad) och en nedre konsol 29 anordnande framför inloppet 21 i höljets främre del.The hose holder 24 is rotatably arranged around a vertical axis 28 which is formed by shaft pins arranged on the upper and lower side of the hose holder 24 which are attached to an upper (not shown) and a lower bracket 29 arranged in front of the inlet 21 in the front part of the housing.
Den i fig 2 visade anordningen fungerar så att de av slangen 13 åstadkomna rörelserna överförs till slanghållaren 24 och vrider denna runt axeln 28 i enlighet med dessa rörelser. Slanganslutningen 23 fungerar därvid som ett fjädrande element och åstadkommer en god följsamhet hos dammsugaren och dämpar häftiga ryck.The device shown in Fig. 2 functions so that the movements produced by the hose 13 are transmitted to the hose holder 24 and rotate it around the shaft 28 in accordance with these movements. The hose connection 23 then functions as a resilient element and provides good compliance with the vacuum cleaner and dampens violent jerks.
