Uppfinnare: 0 L Allen, J T Ferraris och R C Lampe Prioritet begard fran den 18 juli 1960 (USA) Uppfinningen avser en anordning for horstning och renewing av ytor, i synnerhet for rengoring eller skurning av mattor. Anordrxingen dr av den typ, som bestar av en motor med en nedhangande driven axel, en vid axeln fast borste med bojliga borsthar, en ledning for tillforsel av vatska till borsten samt en nedat runt axeln utskjutande mantel, som omger borsten och ledningens utloppsande. Inventors: 0 L Allen, J T Ferraris and R C Lamp Priority requested from 18 July 1960 (USA) The invention relates to a device for hoarding and renewing surfaces, in particular for cleaning or scrubbing carpets. The device is of the type which consists of a motor with a hanging driven shaft, a brush fixed to the shaft with flexible bristles, a line for supplying liquid to the brush and a jacket projecting downwards around the shaft, which surrounds the brush and the pipe outlet.

Enligt uppfinningen har denna 'anordning utformats med en relativt styv mantel, som. Or lostagbart fast vid motorn eh vars undre ande dr utform.ad som en stodyta for att uppbara anordningen pa den yta, som skall reneras. Borstharen ha darvid givits shdan langd, att de i rakt tillstancl stracka sig utanfor stodytan. Den anordnade manteln, som kant satt tjanar som 'skydd mot det flytande rengoringsmedlets utslungning, uppbar hela anordningens tyngd, varigenom sarskilda stadhjul bliva Overflodiga. Genom att manteln dessutom Os mouterad lostagbar, kan anordningen efter mantelns avlagsnande aven anvandas for ,andra andamal. According to the invention, this device has been designed with a relatively rigid jacket, which. Is removably attached to the engine, the lower spirit of which is designed as a support surface to support the device on the surface to be cleaned. The bristles have thus been given such a length that they, in a straight state, extend beyond the support surface. The arranged mantle, which edge served as a protection against the ejection of the liquid detergent, carried the weight of the whole device, whereby special city wheels became redundant. By the fact that the jacket is also Os mouted detachable, the device can also be used for other purposes after the jacket has been removed.

Sparrhakarna kunna fOras radiellt in-at genom att tummen anlagges mat den ena av dem och ett finger mot den andra, varpa sparrhakarna tryckas mot varandra, sa att deras hakandar 58 komma i linje med sparen 54, och skivan 50 kan tagas loss frail Hansen 46. Skivan 50 uppbar en borste bestaende av rela:tivt langa, bojliga borsthar 60, som Ore monterade i en ring eller i stjarnform (fig. 7) och av vilka atminstone en del Oro riktade snett utat, sasom framgar av fig. 2. A rotating brush disc 50 can be releasably attached to Hansen 46 by means of a pair of ratchets 52, which Oro rotatably mounted on the disc to engage in slots 54 in Hansen, as shown in particular in Figs. 6 and 7. Leaf springs 56 attempt to feed the two. sparrhaliarna 52 radially outward, sa. that the hook ends 58 of the rafters are caused to protrude beyond the outer ends of the rafters 54. The ratchets can be moved radially in by placing the thumb with one of them and one finger against the other, warping the ratchets against each other, so that their hook ends 58 are in line with the racks 54, and the disc 50 can be removed frail Hansen 46 The disc 50 bore a brush consisting of relatively long, flexible bristles 60, which Ore mounted in a ring or in star shape (Fig. 7) and of which at least some Oro directed obliquely outwards, as shown in Fig. 2.

Med 62 betecknas generellt ett skort, som Or lostagbart fast vid motorn 10 med hjalp av ett par sparrhakar 64, av vilka en visas i fig. 1, 3 och 4. Dessa sparrhakar aro monterade i urtagningar 66, som utbildats i skOrtet vid deltas motsatta sidor. Sparrhakarna Ore svangbara till och fran ingrepp med slitsar 68, som utformats i motorkapan 12. Skortets 62 undre kant Or utformad som en stodyta 70, vilken befinner sig nagot ovanfor andarna borstharen. 60, da dessa Oro raka, sasom visas i fig. 2. Da. anordningen Or placerad pa en yta, sasom exempelvis en matta, bliva emellertid borstharen ph grand av motorns vikt bdjda Ot sidan sa, att stodytan 70 kommer i kontakt med mattan och uppbar starre delen av vikten. By 62 is generally indicated a skirt which is releasably attached to the motor 10 by means of a pair of ratchets 64, one of which is shown in Figs. 1, 3 and 4. These ratchets are mounted in recesses 66 formed in the skirt at opposite ends. pages. The ratchets Ore pivotable to and from engagement with slots 68 formed in the motor housing 12. The lower edge Or of the skirt 62 is formed as a support surface 70 which is located slightly above the spirits of the bristle. 60, when these concerns are straight, as shown in Fig. 2. Da. device Or placed on a surface, such as a mat, however, the bristles are greatly reduced by the weight of the motor. On the other hand, the support surface 70 comes into contact with the mat and carries the greater part of the weight.

En vatskebehallare 72 Or lostagbart monterad ovanpa motom 10. Den eentrala delen av behallarens botten Or konkav for att tatt passa mot lockets 14 konvexa utsida. Sasom sarskilt framgar av fig. 5, Oro sparrhakar 74 svangbart fasta vid behallarens 72 batten pa ena sidan oin den konlia.va mittdelen samt Oro svangbara till ingrepp med den i motorkapans lock 14 utbildade inloppsdppningen 28, varvid behallaren fastkopplas vid motorn. Upptill Or behallaren forsedd med en pafyllningsoppning, som normalt Or tillsluten me-deist ett lock 76, vilket livarhalles pa sin plats genom friktionsingrepp. I narheten av en av sparrhakarna 74 Or behallarens botten utbildad med en utloppsoppning 78, som delvis Or utformad som ett ventilsate 80, sasom sarskilt visas i fig. 3. Ett ventilelement 82 Or monterat pa en spindel 84, som Or forskjutbart salt genom behallarens ovre vagg. En spiralfjader 86 tjanar till att h011a ventilelementet 82 mat satet 80. En bojlig ledning 88 Or kopplad till utloppet 78 saint leder till en nippel 90, som stracker sig genom skortet 62 nagot nedanfor skivan 50. Ledningen Or lastagbart kopplad till utloppet 78, till nippeln. 90 eller till badadera, sa att skortet 62 och behallaren 72 ej behova vara permanent fdrbundna med varandra. A water tank container 72 Or removably mounted on top of the motor 10. The central part of the bottom of the tank Or concave to fit against the convex outside of the lid 14. As can be seen in particular from Fig. 5, Oro ratchets 74 are pivotally attached to the bottom of the container 72 on one side of the conical center portion and Oro pivotable to engage the inlet opening 28 formed in the hood cover 14, the container being coupled to the engine. At the top, the container is provided with a filling opening, which is normally closed by means of a lid 76, which is held in place by frictional engagement. Near one of the ratchets 74, the bottom of the container is formed with an outlet opening 78, which is partly formed as a valve seat 80, as shown in particular in Fig. 3. A valve element 82 is mounted on a spindle 84, which is displaceable salt through the top of the container. cradle. A coil spring 86 serves to hold the valve member 82 to the satin 80. A flexible conduit 88 is connected to the outlet 78 which leads to a nipple 90 which extends through the skirt 62 slightly below the disc 50. The conductor is releasably connected to the outlet 78, to the nipple. . 90 or to bathers, so that the skirt 62 and the container 72 do not have to be permanently connected to each other.

Ett p0 behallarens 72 ovre vagg svangbart monterat ventilmanovreringsorgan 92 innehailer en slits 94, genom vilken ventilspindeln 84 stracker sig. Derma senare Or vid sin byre ande forsedd med en knopp 96. Ett bOjligt element 98, exempelvis ett snore eller en kedja, liar sin ena ande fast vid manovreringsorganet 92, medan den. andra anden Or fast vid en. ring 100, som romger den ovanfOr Toren 33 befintliga rorstudsen 35 pa sugslangen 37, varigenom snorets eller kedjans 98 ovre Onde Or lOtt tillganglig for manovrering av ventilen. Ringen 100 kan paforas Over rdrstudsen 35, innan denna inskjutes i raret 33. Ringens 100 innerdiameter Or mindre On ytterdiametern for rorets 33 iivre ande och kan darfor ej alida nedat. A valve actuator 92 pivotally mounted on the upper cradle of the container 72 includes a slot 94 through which the valve stem 84 extends. The latter or at its carrying spirit provided with a knob 96. A flexible element 98, for example a cord or a chain, attaches its one spirit to the actuator 92, while it. other spirit Or stuck to one. ring 100, which encloses the rudder nozzle 35 on the suction hose 37 located above the gate 33, whereby the upper end of the cord or chain 98 is easily accessible for maneuvering the valve. The ring 100 can be pushed over the pipe socket 35 before it is inserted into the tube 33. The inner diameter of the ring 100 is smaller than the outer diameter of the upper spirit of the pipe 33 and can therefore not be lowered.

Vid anordningens drift Oro de olika delarna hopmonterade p0. beskrivet satt, och ett lampligt flytande rengoringsmedel har pafyllts i behallaren 72. Vid drift av den dammsugare, till vilken slangen 37 Or kopplad, insuges luft genom oppningen 28, sa. att turbinhjulet 20 bringas att rotera. Lunen strarnmar darvid i pilarnas 102 riktning genom knarbret 31, roren 33 och slangen 37. Vid turbinhjulets rotation bringas axeln 32 att rotera med en reducerad hastighet men med flerfaldigt Rat vridmoment, och borsten 50 bringas ,darvid I sin tur att rotera med borstharen 60 i kontakt med mattan, under det att storre delen av anordningens vikt uppbares av den mot inattan anliggande stodytan 70. During the operation of the device Concern the various parts assembled p0. described, and a suitable liquid cleaning agent has been filled into the container 72. During operation of the vacuum cleaner, to which the hose 37 Or is connected, air is sucked in through the opening 28, sa. causing the turbine wheel 20 to rotate. The groove then strands in the direction of the arrows 102 through the crank 31, the rudder 33 and the hose 37. As the turbine wheel rotates, the shaft 32 is caused to rotate at a reduced speed but at multiple Rat torque, contact with the mat, while most of the weight of the device is supported by the abutment support surface 70.

Da dragning slier i snoret eller kedjan 98, svanges ventilmanovreringsorganet 92 sa., att veatilelementet 82 lyftes fran sitt sate mot verkan av fjadern 86. Harvid strommar vatska genom ledningen 88 och nippeln 90, varifrau den utmatas mot de roterande borstharen 60. Pa. grund av eentrifugalkraften bojas .dessa utat, och de som befinna sig vid eller i narheten av spetsarna ph den stjarna, som — —3 bildas av borsten, gnida mot skOrtets 62 insida. Foretradesvis är rengoringsmedlet av skummande typ, och genom borstharens gnidning mot skortet bringas det i skumning. Istallet for vatska kommer darfor huvudsakligen skum att paforas pa mattan, vilket resulterar i en jamn fordelning av rengoringsmedlet under minimal vatning. Rengoringsmedlets losande verkan i kombination med de roterande borstharens gnidning mot mattan astadkommer ,ett lOsgOrande och avlagsnande av smutspartiklarna frail mattan. As tension slides in the cord or chain 98, the valve actuator 92 is pivoted so that the valve member 82 is lifted from its seat against the action of the spring 86. In this case, liquid flows through the conduit 88 and the nipple 90, from which it is discharged towards the rotating bristles 60. Pa. due to the centrifugal force, these are bent outwards, and those at or near the tips of the star, which are formed by the brush, rub against the inside of the skirt 62. Preferably, the cleaning agent is of the foaming type, and by rubbing the bristle against the scouring it is brought to foaming. Instead of water, therefore, foam will mainly be applied to the carpet, resulting in an even distribution of the detergent during minimal watering. The release action of the cleaning agent in combination with the rubbing of the rotating bristles against the carpet creates a loosening and removal of the dirt particles from the carpet.

Sasom redan namnts, uppbares storre de-Ten av aggregatets vikt av den pa skOrtet 62 utfonnade stodytan 70. Samtidigt tjanar skortet till att fiirhindra, att flytande rengoringsmedel pa grund av ,centrifugaikraften kastas utat av borsten. Det mot skortets insida utslungade rengoringsmedlet rinner medal till skortets undre kant, .dar det omedelbart uppsamlas av borstharen, vilka sasom namnts aro bojda .utat. Sava' skortet 62 som behallaren 72 ha sä liten vikt som mojligt. Det är ingen som heist forde1 med att utforma en lung anordning, eftersom praktiskt taget ingen extra vikt paliires Pd borstharen 60. As already mentioned, greater weight of the unit is borne by the support surface 70 formed on the skirt 62. At the same time, the skirt serves to prevent liquid detergent from being thrown out of the brush due to the centrifugal force. The cleaning agent thrown out towards the inside of the skirt flows medal to the lower edge of the skirt, where it is immediately collected by the bristle, which as it is called is curved. Sava 'skirt 62 as the container 72 should have as little weight as possible. There is no heist forde1 in designing a lung device, since practically no extra weight paliires Pd the bristle 60.

Om det .ar onskvart ,att anvanda motorn 10 for andra andamal n for rengoring av mat-tor, kan borsten 50 avlagsnas genom att sparrhakarna faros radiellt mat, och skortet 62 och behallaren 72 kunna avtagas genom att sparrhakarna 64 och 74 svangas frail ingrepp med sparen. 68 resp. inloppet 28. Avensd. kan ledningen 88 losgoras fra.n antingen utloppet 78 eller nippeln 90, sa att behallaren blir hell fri fran skOrtet. Etter det att rorstudsen 35 utdragits ur angransande rordel 33, kan ringen 100 lasgoras. If it is necessary to use the motor 10 for other purposes than for cleaning mats, the brush 50 can be removed by placing the ratchets in radial food, and the skirt 62 and the container 72 can be removed by swinging the ratchets 64 and 74 in a free engagement with save. 68 resp. inlet 28. Avensd. the conduit 88 can be detached from either the outlet 78 or the nipple 90, so that the container is completely free from the skirt. After the rudder nozzle 35 has been pulled out of the adjacent rudder part 33, the ring 100 can be welded.

Anordningen enligt uppfinningen ar ej be gransad till det ovan beskrivna utfOrandet, vilket endast ar att betrakta som ett utforingsexempel. The device according to the invention is not limited to the embodiment described above, which is only to be considered as an exemplary embodiment.
