Description
Apparat til slibning/pudsning eller afrensning af en overfladeApparatus for grinding / polishing or cleaning a surface
Opfindelsens områdeFIELD OF THE INVENTION
Den foreliggende opfindelse angår et apparat til slibning/pudsning eller afrensning af en overflade, omfattende mindst en slibeenhed, en motor, en skærm og et håndtag med skaft og håndgreb, hvor nævnte slibeenhed er en rotérbar og fortrinsvis vandret arrangeret slibecylinder, der drives af motoren, og som i en cylinderoverflade er forsynet med et antal slibeelementer, hvor nævnte skærm delvis omslutter nævnte slibeenhed, og hvor nævnte håndtag er forbundet med nævnte skærm.The present invention relates to an apparatus for grinding / polishing or cleaning a surface comprising at least one abrasive unit, motor, screen and handle with handle and handle, said abrasive unit being a rotatable and preferably horizontally arranged abrasive cylinder driven by the motor. and which is provided on a cylinder surface with a plurality of abrasive elements, said screen partially enclosing said abrasive unit and said handle being connected to said screen.
Opfindelsens baggrund Når eksempelvis et gammelt eller misligholdt trægulv skal sættes i stand, bliver det typisk afhøvlet/afslebet, inden det slutbehandles med olie eller lak.BACKGROUND OF THE INVENTION When, for example, an old or defaults wooden floor is to be repaired, it is typically leveled / sanded before being finalized with oil or varnish.
Endvidere findes der behov for slibning/pudsning af overflader af glasfiber eller lignende fiberarmerede kompositoverflader for at klargøre disse til overfladebehand-ling/maling. Som eksempler kan nævnes vindmøllevinger, bådskrog, båddæk.Furthermore, there is a need for grinding / polishing glass fiber surfaces or similar fiber-reinforced composite surfaces to prepare these for surface treatment / painting. Examples include wind turbine blades, boat hulls, boat decks.
Ligeledes er der behov for slibning af metalflader for klargøring af disse til overflade-behandling/maling.Also, grinding of metal surfaces is needed to prepare them for surface treatment / painting.
De apparater, der anvendes, er typisk gulvhøvle/gulvslibere med enten et antal roterende rondeller med cirkulære slibeskiver eller en slibecylinder. Slibecylinderen kan have et omsluttende slibebånd eller slibeelementer i cylindero verfladen.The appliances used are typically floor planer / floor grinders with either a number of rotating rounds with circular grinding wheels or a grinding cylinder. The grinding cylinder may have an enclosing grinding belt or grinding elements in the cylinder surface.
De kendte apparater er typisk store og tunge apparater, der ikke nemt kan løftes af en person, og vægten medfører, at de kan være svære at manøvrere. Endvidere er disse apparater almindeligvis forsynet med højdejusterbare hjul, hvilket ikke er en fordel, da slibecylinderne ikke optimalt vil kunne følge den underliggende flades konjunktur. Afstanden mellem slibecylinderen og den underliggende overflade vil blive bestemt af den underliggende flades konjunktur de steder, hvor hjulene kører. Støttehjul for appa- ratet vil endvidere ofte hindre, at der sker slibning/pudsning op til en tilstødende væg/hjørne.The known devices are typically large and heavy devices that cannot be easily lifted by a person, and the weight means that they can be difficult to maneuver. Furthermore, these devices are generally provided with height-adjustable wheels, which is not an advantage, since the grinding cylinders will not be able to optimally follow the cyclical nature of the underlying surface. The distance between the abrasive cylinder and the underlying surface will be determined by the cycling of the underlying surface at the places where the wheels are driven. Furthermore, support wheels for the appliance will often prevent grinding / polishing up to an adjacent wall / corner.
Ligeledes vil et håndtag være fast forbundet med apparatets slibeenhed via en gaffelgren, der udgør en endedel af styret, og som har en grendel placeret på hver side af slibeenheden. En sådan konstruktion kendes for eksempel fra WO 2006092138 fra samme opfinder. En sådan konstruktion med en gaffelgren forbundet med hver sideplade vanskeliggør også slibning/pudsning helt op til en kant og ind i hjørner. Håndtaget er fast monteret, så det kun kan strække sig til den ene side af apparatet. Dette gør det nødvendigt at skulle friløfte apparatet eller foretage vanskelige manøvrer, når apparatet benyttes til at slibe langs vægge og helt ind i et hjørne.Also, a handle will be firmly connected to the grinding unit of the apparatus via a fork branch constituting an end portion of the guide and having a latch located on each side of the grinding unit. Such a construction is known, for example, from WO 2006092138 from the same inventor. Such a construction with a fork branch connected to each side plate also makes grinding / polishing all the way up to an edge and into corners. The handle is firmly mounted so that it can only extend to one side of the device. This makes it necessary to release the appliance or make difficult maneuvers when the appliance is used to grind along walls and into a corner.
Endvidere er der et problem ved afrensning af overflader i byrum, hvor fliser og asfalt kan være forurenet, for eksempel af tyggegummi. Afrensning har hidtil været foretaget med store maskiner og med kombination af mekaniske, kemiske og/eller termisk behandling. På grund af disse maskiners størrelse har det være vanskeligt at foretage afrensning af mindre overflader og overflader tæt op til vægge, kantsten, bænke og lignende.Furthermore, there is a problem with cleaning surfaces in urban spaces where tiles and asphalt may be contaminated, for example by chewing gum. So far, cleaning has been done with large machines and with a combination of mechanical, chemical and / or thermal treatment. Due to the size of these machines, it has been difficult to clean up smaller surfaces and surfaces close to walls, curbs, benches and the like.
Opfindelsens formålThe object of the invention
Det er formålet med den foreliggende opfindelse at angive et apparat, der benytter en vandret arrangeret slibecylinder, og som er let at manøvrere især ved slibning/pudsning samt afrensning af overflader langs vægge og op mod et hjørne, og som har en lav egenvægt. Endvidere er det formålet at angive et apparat, hvor det er muligt at opnå en slibning/pudsning samt afrensning, som går så tæt som muligt ind i hjørner og ind til tilstødende lodrette flader, så som vægge.It is the object of the present invention to provide an apparatus which uses a horizontally arranged abrasive cylinder and which is easy to maneuver especially in the case of grinding / polishing and cleaning of surfaces along walls and up to a corner and having a low intrinsic weight. Furthermore, the object is to indicate an apparatus where it is possible to obtain a grinding / polishing and cleaning which goes as close as possible into corners and into adjacent vertical surfaces, such as walls.
Beskrivelse af opfindelsenDescription of the Invention
Dette opnås med et apparat af den i indledningen til krav 1 beskrevne art, der er særpræget ved, at apparatet omfatter en sideplade, at skærmen er monteret på sidepladen, at skærmen er dannet af en delcylindrisk plade, der i sin side har en åbning, hvor slibeelementerne rager ud, og som ved sin ende modsat sidepladen er lukket af en endeplade, at motoren og slibecylinderen er monteret på sidepladen, at håndtaget er monteret svingbart på sidepladen om et centralt leje med en midtakse, der er parallel med slibe cylinderens midtakse og at håndtaget er forsynet med fikseringsorganer, der kan bringes i indgreb med modsvarende fikseringsorganer på sidepladen for fastholdelse af håndtaget i mindst en stilling skråt opefter og udefter på hver side af apparatet.This is achieved by an apparatus of the kind described in the preamble of claim 1, characterized in that the apparatus comprises a side plate, that the screen is mounted on the side plate, that the screen is formed by a subcylindrical plate having in its side an opening, the abrasive elements projecting and which at their end opposite the side plate is closed by an end plate, that the motor and the grinding cylinder are mounted on the side plate, that the handle is pivotally mounted on the side plate about a central bearing with a central axis parallel to the center axis of the cylinder and the handle is provided with fixing means which can be engaged by corresponding fixing means on the side plate for holding the handle in at least one position obliquely upwards and outwards on each side of the apparatus.
Apparatet et let og mekanisk enkelt og kan slibe stort set helt ind i hjørner, idet håndtaget blot svinges mellem sine to stillinger ved slibning ind mod et hjørne langs en første væg og ved slibning væk fra hjørnet langs en tilstødende sidevæg. Slibeappara-tet kan gå ganske tæt ind til en væg og et hjørne, da sidepladen med alle elementer monteret vender væk fra væggen. Det er således alene endepladen, der adskiller slibeelementerne fra væggen. Dette har yderligere den fordel, at der ikke vil være risiko for, at slibeelementerne beskadiger fodlister og vægge.The apparatus is a light and mechanical simple and can grind almost completely into corners, the handle being simply pivoted between its two positions by grinding against a corner along a first wall and by grinding away from the corner along an adjacent side wall. The grinding device can go quite close to a wall and a corner, as the side plate with all the elements mounted faces away from the wall. Thus, only the end plate separates the abrasive elements from the wall. This further has the advantage that there will be no risk of the grinding elements damaging the moldings and walls.
Apparatet er med specielle slibeelementer egnet til afrensning af overflader i byrum, for eksempel for at fjerne tyggegummi fra fliser og asfalt.The device is equipped with special abrasive elements for cleaning surfaces in urban spaces, for example to remove chewing gum from tiles and asphalt.
Endvidere er apparatet velegnet til at slibe/pudse profilerede kompositbrædder.Furthermore, the apparatus is suitable for grinding / polishing profiled composite boards.
Ifølge en foretrukket udførelsesform er apparatet ifølge opfindelsen særpræget ved, at håndtaget har en vinkelbukket del, så håndtagets skaft forløber i et lodret plan, der stort set er placeret midt på apparatet. Herved fås en symmetrisk konstruktion, som er let at manøvrere.According to a preferred embodiment, the apparatus according to the invention is characterized in that the handle has an angularly bent portion, so that the handle of the handle extends in a vertical plane which is largely located in the middle of the apparatus. This provides a symmetrical structure that is easy to maneuver.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at håndtagets håndgreb har en bredde, der er mindre en slibecylinderens aksiale udstrækning i retning væk fra sidepladen. Herved vil apparatet kunne køre helt tæt til en væg, idet håndgrebet ikke vil begrænse muligheden for, at slibecylinderen kan køre helt ind til en væg.According to a further embodiment, the apparatus according to the invention is characterized in that the handle of the handle has a width which is less than the axial extension of the abrasive cylinder in a direction away from the side plate. This will allow the device to run very close to a wall, as the handle will not limit the possibility that the grinding cylinder can run all the way to a wall.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at håndtagets to stillinger er ca. 45° i forhold til vandret. Dette vil i praksis give den mest hensigtsmæssige arbejdsstilling. Vinklen kan dog ændres +/- 10°. Inden for et sådan interval vil det stadig være muligt at få en ergonomisk arbejdsstilling. Dette er især tilfældet, hvis håndtaget er længdejusterbart. Derfor er opfindelsen ifølge en yderligere udførelsesform særpræget ved, at håndtagets skaft er længdejusterbart.According to a further embodiment, the apparatus according to the invention is characterized in that the two positions of the handle are approx. 45 ° to the horizontal. In practice, this will provide the most appropriate posture. However, the angle can be changed +/- 10 °. Within such an interval, it will still be possible to get an ergonomic posture. This is especially the case if the handle is length adjustable. Therefore, according to a further embodiment, the invention is characterized in that the handle of the handle is length adjustable.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at håndtagets fikseringsorganer er en fjederbelastet pal, og at sidepladens modsvarende fikseringsorganer er to huller til optagelse af palen, som af fjederen trykkes ind i hullerne, når palen er liniestillet med et af hullerne. Herved fås en nem betjening, idet en bruger efter kørsel langs en væg ind mod et hjørne blot behøver at trække palen ud imod virkningen fra fjederen og drejer apparatet om mod den næste væg og svinger håndtaget til den modsatte position, hvor det automatisk låses, da fjederen fører palen ind i hullet.According to a further embodiment, the apparatus according to the invention is characterized in that the fixing means of the handle are a spring loaded pawl and that the corresponding fixing means of the side plate are two holes for receiving the pawl which are pressed into the holes by the spring when the pawl is aligned with one of the holes. This provides easy operation as a user, after driving along a wall towards a corner, simply has to pull the pile out against the action of the spring and turns the device towards the next wall and swings the handle to the opposite position where it automatically locks, as the spring leads the pile into the hole.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at håndtaget er lejret svingbart i et leje i afstand fra håndtagets ende fjernest fra håndtagets håndgreb, og at håndtagets fikseringsorganer er placeret nærmere nævnte ende. Herved vil den yderste ende af håndtaget kunne placeres ved en ydre del af skærmen nær ved den cylindriske skærms åbne bund. Dette letter manøvreringen.According to a further embodiment, the apparatus according to the invention is characterized in that the handle is pivotally mounted in a bearing at a distance from the end of the handle farthest from the handle of the handle and that the fixing means of the handle are located nearer said end. This allows the outer end of the handle to be positioned at an outer part of the screen near the open bottom of the cylindrical screen. This facilitates maneuvering.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at slibeelementeme er udskiftelige, idet de er monteret i aksialt forløbende spor i cylinderoverfladen. Således kan skærmen blot afmonteres fra sidepladen, og derefter kan slibeelementeme let udskiftes, når de er slidte, eller når apparatet skal forsynes med anden type slibeelementer.According to a further embodiment, the apparatus according to the invention is characterized in that the abrasive elements are interchangeable in that they are mounted in axially extending grooves in the cylinder surface. Thus, the screen can simply be removed from the side plate, and then the grinding elements can be easily replaced when worn or when the apparatus is to be provided with another type of grinding elements.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at slibeelementeme har en udstrækning fra sidepladen til skærmens endeplade. Herved sikres det, at apparatet kan slibe tæt op til en væg, idet alene endepladens tykkelse vil være afgørende for den del af overfladen, som ikke kan slibes/pudses.According to a further embodiment, the apparatus according to the invention is characterized in that the grinding elements extend from the side plate to the end plate of the screen. This ensures that the appliance can grind close up to a wall, since only the thickness of the end plate will determine the part of the surface that cannot be sanded / polished.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at motoren er placeret lodret over slibecylinderen, og at motoren driver slibecylinderen via et remtræk. Dette giver en god vægtfordeling og gør det muligt at fremstille apparatet med en meget lav vægt. I praksis har det vist sig muligt at opnå apparater med en vægt på 12-15 kg for apparater med slibecylinder med en diameter på 300 mm og en længde på 200 mm.According to a further embodiment, the apparatus according to the invention is characterized in that the motor is positioned vertically above the abrasive cylinder and that the motor drives the abrasive cylinder via a belt drive. This gives a good weight distribution and makes it possible to manufacture the device with a very low weight. In practice, it has been found possible to obtain appliances weighing 12-15 kg for appliances with abrasive cylinders with a diameter of 300 mm and a length of 200 mm.
Ifølge en yderligere udførelsesform er apparatet ifølge opfindelsen særpræget ved, at slibeelementeme omfatter sandpapiremner, der fortrinsvis er opslidset fra deres ydre kant indad mod cylinderoverfladen, og som har en kornstørrelse fra 36 til 60. Herved opnås et apparat, der er særlig velegnet til anvendelse ved afrensning af overflader af fliser og asfalt, for eksempel for fjernelse af tyggegummi. Sandpapiremneme og slibecylindrene kan være af den type, som forhandles af firmaet Flex Trim A/S, Glyngø-re, Danmark.According to a further embodiment, the apparatus according to the invention is characterized in that the abrasive elements comprise sandpaper blanks, which are preferably slit from their outer edge inwards towards the cylinder surface, and which have a grain size from 36 to 60. This provides an apparatus which is particularly suitable for use in cleaning surfaces of tiles and asphalt, for example for chewing gum. The sandpaper strips and grinding cylinders may be of the type negotiated by the company Flex Trim A / S, Glyngøre, Denmark.
Opfindelsen angår endvidere en anvendelse af apparatet til afrensning af overflader, for eksempel overflader i byrum, for at fjerne tyggegummi fra fliser og asfalt.The invention further relates to the use of the apparatus for cleaning surfaces, for example surfaces in urban spaces, to remove chewing gum from tiles and asphalt.
