Opfindelsen angår et tæppefejeapparat af den i indledningen til krav 1 angivne art.The invention relates to a carpet sweeping apparatus of the type specified in the preamble of claim 1.
Ved kendte tæppefejeapparater af den omtalte art drives hjælpebørsten eller -børsterne af et ved hver børste anbragt drivhjul. Således kendes fra tysk fremlæggelsesskrift nr.In known carpet sweeping devices of the type mentioned, the auxiliary brush or brushes are driven by a drive wheel arranged at each brush. Thus known from German submission no.
2.055.841 et apparat, hvor drivhjulet er anbragt i det indre af S den skålformede børstekrans på hjælpebørsten. Da drivhjulets ^ aksel forløber næsten vinkelret på hjælpebørstens aksel, er der — mellem drivhjulet og hjælpebørsten indskudt et vinkelgear. End- Ω i t a 2 145113 videre står drivhjulet omtrent oprejst, således at hjælpebørsten ikke kan være flad.2,055,841, an apparatus in which the drive wheel is located in the interior of S the cup-shaped brush ring on the auxiliary brush. Since the shaft of the drive wheel extends almost perpendicular to the shaft of the auxiliary brush, an angular gear is inserted between the drive wheel and the auxiliary brush. End- Ω i t a 2 145113 further the drive wheel is approximately upright so that the auxiliary brush cannot be flat.
Formålet med opfindelsen er at anvise et tæppefeje-apparat uden en kompliceret og dyr transmission mellem drivhjulet og hjælpebørsten.The object of the invention is to provide a carpet sweeping apparatus without a complicated and expensive transmission between the drive wheel and the auxiliary brush.
Dette opnås ifølge opfindelsen ved den i krav 1 anviste konstruktion.This is achieved according to the invention by the construction indicated in claim 1.
Ved den anviste udformning er drivhjulet tallerkenformet og skråtstillet, således at en lav byggehøjde opnås. Endvidere har drivhjulsnavet et urundt ydre tværsnit og indgriber med et modsvarende hul i hjælpebørsten. Drivhjulet er derved kraftoverførende med hjælpebørsten, således at et vinkelgear kan undværes.With the design indicated, the drive wheel is plate-shaped and inclined, so that a low construction height is achieved. Furthermore, the drive wheel hub has a non-round outer cross section and engages with a corresponding hole in the auxiliary brush. The drive wheel is thus power-transmitting with the auxiliary brush, so that an angular gear can be dispensed with.
Ophænget for hjælpebørsten og tilhørende drivhjul kan ifølge opfindelsen med fordel være indrettet som angivet i krav 2.According to the invention, the suspension for the auxiliary brush and associated drive wheels can advantageously be arranged as stated in claim 2.
Derved opnås på enkel vis, at de til kipning af hjælpebørsten nødvendige momenter frembringes af drivhjulet selv, samtidig med at drivhjulet som følge af sin skrå stilling indtager en for kontakten med underlaget gunstig stilling uanset børstens kipstilling. Kontakten mellem hjulet og underlaget ville være sikret under alle forhold, også hvor underlaget er ujævnt som følge af hjulets aksiale forskydelighed.Thereby it is achieved in a simple manner that the moments necessary for tilting the auxiliary brush are produced by the drive wheel itself, at the same time as the drive wheel, due to its inclined position, occupies a position favorable for the contact with the ground regardless of the tilt position of the brush. The contact between the wheel and the ground would be ensured in all conditions, even where the ground is uneven due to the axial displacement of the wheel.
For at sikre, at hjælpebørsten under alle forhold uanset apparatets bevægelsesretning fejer indad under apparatet, kan børstens drivhjul ifølge opfindelsen være anbragt som angivet i krav 3.In order to ensure that the auxiliary brush sweeps inwards under the apparatus in all conditions, regardless of the direction of movement of the apparatus, the drive wheels of the brush according to the invention can be arranged as stated in claim 3.
Formålstjenligt er hjælpebørsten lejret således, som anført i krav 4. Derved opnås en enkel og konstruktiv løsning af problemet med børstens lejring og samtidig sikres, at børsten deltager i lejeelementets, af hjulet styrede kipbevægelse.The auxiliary brush is expediently mounted as stated in claim 4. This provides a simple and constructive solution to the problem of the brush's bearing and at the same time ensures that the brush participates in the tilting movement of the bearing element, controlled by the wheel.
I en udførelsesform, som angivet i krav 5» opnås, at drivhjulet under alle forhold og uanset ujævnheder i underlaget holdes i fast anlæg med en af fjederen bestemt kraft. Dette har betydning for friktionen mellem underlaget og hjulet, dvs. for den effekt, som hjulet er i stand til at overføre til børsten. Hvis apparatet hæves op fra underlaget, vil anslaget for hjulet hindre dette i at falde ud. Anslaget kan ifølge opfindelsen særlig enkelt udgøres af en skive, som er fastholdt ved hjælp af en i tappens endeflade indsat skrue.In an embodiment as stated in claim 5 ', it is achieved that the drive wheel is kept in fixed abutment with all forces and regardless of irregularities in the ground with a force determined by the spring. This has an effect on the friction between the ground and the wheel, ie. for the power that the wheel is able to transfer to the brush. If the appliance is raised from the ground, the stop for the wheel will prevent it from falling out. According to the invention, the stop can in particular be constituted by a disc which is held by means of a screw inserted in the end face of the pin.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor 3 145113 fig. 1 viser i perspektiv et fejeapparat ifølge opfindelsen, set aksialt ovenfra, og fig. 2 i forstørret snit apparatets ene hjælpebørste med tilhørende drivhjul og ophæng.The invention will be explained in more detail below in connection with the drawing, in which fig. 1 shows in perspective a sweeping apparatus according to the invention, seen axially from above, and fig. 2 in enlarged section one auxiliary brush of the appliance with associated drive wheels and suspension.
Det på tegningen viste tæppefejeapparat består på sædvanlig måde af et hus 10, som er sammensat af bund rammen 11 og en dækselformet overdel 12. Apparatet betjenes ved hjælp af et ikke vist skaft, som er forbundet med huset gennem en U-formet bøjle 13, der er drejeligt lejret udvendigt til rammen 11. Apparatet er på undersiden forsynet med ikke viste kørehjul og en af kørehjulene drevet børstevalse til opfejning af skam i samlebakker eller rum under dækslet. Både hjulene og børstevalsen er lejret til rammen 11 på en måde, som ikke skal beskrives næraere her. Børstevalsen strækker sig på tværs mellem rammens sidestykker og er som følge heraf kun virksom i en del af appåfatets bredde. For at øge apparatets arbejdsbredde, er apparatet udstyret med to hjælpebør-ster 23, der er virksomme helt ud under apparatets sider. Hjælpe-børsterne gør det muligt at feje helt ind til vægge og afsats.The carpet sweeping apparatus shown in the drawing usually consists of a housing 10, which is composed of the bottom frame 11 and a cover-shaped upper part 12. The apparatus is operated by means of a shaft (not shown), which is connected to the housing through a U-shaped bracket 13, there is a rotatable bearing on the outside of the frame 11. The appliance is fitted on the underside with drive wheels (not shown) and one of the drive wheels driven brush roller for sweeping shame in collecting trays or compartments under the cover. Both the wheels and the brush roller are mounted to the frame 11 in a manner which will not be described in more detail here. The brush roller extends transversely between the side pieces of the frame and as a result is only effective in a part of the width of the appendage. To increase the working width of the appliance, the appliance is equipped with two auxiliary brushes 23 which are operative completely below the sides of the appliance. The auxiliary brushes make it possible to sweep all the way to walls and ledges.
De to hjælpebørster 23 er anbragt i hver side af apparatet i dettes forreste ende og består hver af en roterbar, kopformet børste med børstehårene anbragt i en krans 23'. Kopbørsten virker kun i anlæg mod underlaget med en del af sin omkreds, dvs. med en del af børstekransen 23', og den er til dette formål anbragt med stejlt skråtstillet rotationsakse. Samtidig er børsten kipbar om en vandret akse, der strækker sig vinkelret på apparatets bevægelsesretning.The two auxiliary brushes 23 are arranged on each side of the apparatus at its front end and each consists of a rotatable, cup-shaped brush with the bristles arranged in a ring 23 '. The cup brush only works in abutment against the surface with part of its circumference, ie. with a part of the brush ring 23 ', and for this purpose it is arranged with a steeply inclined axis of rotation. At the same time, the brush is tiltable about a horizontal axis that extends perpendicular to the direction of movement of the appliance.
Til hver hjælpebørste 23 hører et tallerkenformet drivhjul 52, der er anbragt indvendigt under den respektive kopbørste 23. Drivhjulet 52 er lejret drejeligt og aksialt forskydeligt på en akseltap 53, der strækker sig skråt nedad fra et lejeelement 54, hvortil også kopbørsten 23 er lejret. Lejeelementet 54 er forsynet med to lejetappe 55, hvormed lejeelementet er ophængt kipbar i apparatets hus 10. Kipaksen er som allerede anført våndret.To each auxiliary brush 23 belongs a disc-shaped drive wheel 52, which is arranged internally below the respective cup brush 23. The drive wheel 52 is mounted rotatably and axially displaceably on a shaft pin 53 extending obliquely downwards from a bearing element 54, to which also the cup brush 23 is mounted. The bearing element 54 is provided with two bearing pins 55, with which the bearing element is suspended and can be tilted in the housing 10 of the apparatus. As already stated, the tilt axis is horizontal.
Lejetappen 53 er rettet skråt nedad og udad mod den af husets sidevæge, som den respektive hjælpebørste virker under. Herved vil drivhjulet 52 virke i anlæg mod underlaget med den del af periferien, som vender indad under huset. Hjulet har som nævnt tallerkenform og er forsynet med et centralt nav 56, hvori der findes en til lejetappen 53 svarende boring. Udvendigt er navet forsynet 145113 4 med fremspring, der griber ind i tilsvarende formede udsparinger i en central åbning i kopbørstens nav 58. Fremspringene tjener til at udføre hjulets drejebevægelse i forhold til børsten.The bearing pin 53 is directed obliquely downwards and outwards towards that of the side wall of the housing under which the respective auxiliary brush acts. Hereby the drive wheel 52 will act in abutment against the ground with the part of the periphery which faces inwards under the housing. As mentioned, the wheel has a plate shape and is provided with a central hub 56, in which there is a bore corresponding to the bearing pin 53. Externally, the hub is provided 145113 4 with projections which engage in correspondingly shaped recesses in a central opening in the hub 58 of the cup brush. The projections serve to perform the rotational movement of the wheel relative to the brush.
Til børstens 23 drejelige ledning er lejeelementet 54 på undersiden forsynet med en lejeboring i form af en cylindrisk udsparing 60. I denne udsparing er børsten indsat med en opad vendende del af et nav 58, som til det formål har en udvendig cylindrisk lejeflade 59. Det bemærkes, at lejetappen 53 strækker sig ned gennem udsparingen 60.For the rotatable conduit of the brush 23, the bearing element 54 is provided on the underside with a bearing bore in the form of a cylindrical recess 60. In this recess the brush is inserted with an upwardly facing part of a hub 58, which for this purpose has an outer cylindrical bearing surface 59. it is noted that the bearing pin 53 extends down through the recess 60.
Omkring lejetappen 53 mellem børsten 23 og hjulet 52 er indsat en skruetrykfjeder 61, som dels tjener til at holde børsten på plads i udsparingen 60, dels til at holde hjulet i ef-tergiveligt anlæg mod underlaget. For at hindre fjederen i at støde hjulet helt ud fra lejetappen 53, f.eks. når apparatet løftes op fra underlaget, er der i enden af lejetappen 53 anbragt en sikring i form af en skive 63, der er fastholdt af en skrue 62. Skiven danner et anslag for hjulet.Around the bearing pin 53 between the brush 23 and the wheel 52, a helical compression spring 61 is inserted, which partly serves to hold the brush in place in the recess 60, partly to keep the wheel in resilient abutment against the ground. To prevent the spring from projecting the wheel completely from the bearing pin 53, e.g. when the apparatus is lifted up from the ground, a fuse in the form of a disc 63 is provided at the end of the bearing pin 53, which is held by a screw 62. The disc forms an abutment for the wheel.
Under brugen bevæges apparatet over underlaget frem og tilbage. Ved bevægelse fremad kipper lejeelementet 54 bagover omkring den vandrette kipakse under virkning af det moment, friktionen mellem hjulet 52 og underlaget giver anledning til. I den bagover kippede stilling vil børsten 23 være i anlæg mod underlaget med den fremad i bevægelsesretningen vendende del af periferien. Da hjulet 52, som allerede anført, samtidig er i kontakt med underlaget med den indad vendende del af periferien, vil 'hjulets og dermed også børstens rotationsretning være således, at børstens virksomme del bevæger sig udefra og indefra i forhold til huset 10. Ved bevægelse af apparatet bagud vil lejeele-mentet 54 kippe fremover, og det vil nu være børstens bageste del, der er i anlæg mod underlaget. Da samtidig hjulets og børstens rotationsretning ændres, vil børsten også i dette tilfælde bevæge sig udefra og indad med sin virksomme del. Det vil altså sige, at børsten 23 i alle tilfælde uanset apparatets bevægelsesretning fejer skarnet ind under huset, hvor den videre opsamling sker ved hjælp af valsebørsten.During use, the appliance moves back and forth over the surface. When moving forwards, the bearing element 54 tilts backwards about the horizontal tilt axis under the action of the torque which the friction between the wheel 52 and the ground gives rise to. In the rearwardly tilted position, the brush 23 will abut against the ground with the part of the periphery facing forwards in the direction of movement. Since the wheel 52, as already stated, is at the same time in contact with the ground with the inwardly facing part of the periphery, the direction of rotation of the wheel and thus also the brush will be such that the active part of the brush moves from the outside and inside relative to the housing 10. When moving of the apparatus to the rear, the bearing element 54 will tilt forward, and it will now be the rear part of the brush which abuts against the ground. Since at the same time the direction of rotation of the wheel and the brush changes, the brush will also in this case move from the outside and inwards with its active part. This means that the brush 23 in all cases, regardless of the direction of movement of the apparatus, sweeps the notch under the housing, where the further collection takes place by means of the roller brush.
Det bemærkes, at apparatet ikke nødvendigvis behøver at have to hjælpebørster 23. X visse tilfælde vil en børste anbragt i et hjørne af apparatet være tilstrækkeligt.It is noted that the appliance does not necessarily have to have two auxiliary brushes 23. In some cases a brush placed in a corner of the appliance will suffice.
