Description
Oppfinnelsen angår et rivbrett som angitt i innledningen The invention relates to a tearing board as indicated in the introduction
til hovedkravet. to the main requirement.
Fra DE ålment tilgjengelig patentsøknad 1 943 110 er der From DE generally available patent application 1 943 110 is there
kjent et slikt rivbrett hvor sideflatene og baksiden av riv- known such a tear-off board where the side surfaces and the back of the tear-
platen er utformet med en glatt overflate med lukkede celler. the plate is designed with a smooth surface with closed cells.
Som følge av denne utformning kan det ikke utelukkes at vann As a result of this design, it cannot be ruled out that water
eller mørtel som spruter av fra rivbrettets bakside, påvirker den allerede pussede flate. or mortar that splashes off the back of the squeegee affects the already plastered surface.
Fra DE bruksmønster 1 831 764 er der kjent et rivbrett From DE utility model 1 831 764 a tear board is known
hvor der på en vanlig plate som er forsynt med et håndtak, er anordnet et belegg av skumplast som har sideflater som strekker seg rettvinklet i forhold til hverandre. Den skumplast som anvendes i belegget, kan ha enten lukkede eller åpnede porer. where on an ordinary plate which is provided with a handle, a coating of foam plastic is arranged which has side surfaces which extend at right angles to each other. The foam plastic used in the coating can have either closed or open pores.
I sistnevnte tilfelle opptar skumplasten vann på samme måte In the latter case, the foam plastic absorbs water in the same way
som en svamp. For at dette skal være mulig, må skumplasten være myk og tvers igjennom ha en åpen cellestruktur. Hensikten med denne forholdsregel er å skaffe en erstatning for et riv- like a sponge. For this to be possible, the foam must be soft and have an open cell structure throughout. The purpose of this precaution is to provide compensation for a demolition
brett med filtoverflate, samtidig som den myke, elastiske skum- board with a felt surface, while the soft, elastic foam

korn bort fra den overflate som skal glattes. grain away from the surface to be smoothed.
Til grunn for oppfinnelsen ligger den oppgave å videre- The invention is based on the task of further-
utvikle et rivbrett av den art som er angitt i innledningen til krav 1, på en slik måte at man såvidt mulig unngår å påvirke den allerede pussede flate med vann eller mørtelrester som spruter av fra brettet. develop a tear board of the type specified in the introduction to claim 1, in such a way that as far as possible one avoids affecting the already plastered surface with water or mortar residues that splash off from the board.
Denne oppgave blir ifølge oppfinnelsen løst ved de trekk According to the invention, this task is solved by the features
som er angitt i karakteristikken i krav 1. Vann eller mørtel som legger seg på baksiden av rivbrettet, blir i første rekke fastholdt på dette på grunn av baksidens ruhet. Ved hjelp av rillene eller rennene vil allikevel vann eller mørtel som løsner fra overflaten, føres bort, nærmere bestemt fordelt over en stor flate. Der finner det altså sted en løsning av bort-sprutende vann resp. mørtel i små dråper eller små stykker. which is stated in the characteristic in claim 1. Water or mortar that settles on the back of the tear board is primarily retained on this due to the roughness of the back. With the help of the grooves or gutters, however, water or mortar that loosens from the surface will be carried away, more precisely distributed over a large surface. There, therefore, takes place a solution of splashing away water resp. mortar in small drops or small pieces.
Også på de ru sideflater fås der en tilsvarende heft- og for-delingsvirkning for vannet resp. mørtelen. Det har i praksis vist seg at der på denne måte i stor utstrekning kan unngås en påvirkning av den allerede pussede flate, og at arbeids-resultatet således blir bedre med rivbrettet ifølge oppfinnelsen. Når de i overflaten liggende celler er åpnet f.eks. ved fresing eller lignende, foreligger der ikke lenger på disse sideflater noen ved støpingen tildannet hinne og dermed heller ingen fare for at overflaten her er hardere enn i det indre av rivplaten. Dette fører igjen til at der etter en viss brukstid ikke dannes noen harde bukler som rager ut fra sideflatene, og som kan føre til en medtrekking av mørtel, dvs. en påvirkning av den allerede pussede flate. Samtidig sikres det som følge av denne bortfresing eller lignende av sideflatene at alle sideflater vil strekke seg vinkelrett på hverandre, hvorved igjen pussingen av innvendige hjørner samt fremstillingen av nøyaktig vinkelrett på hinannen forløpende innerkanter lettes. Ved denne avretting av de korte sideflater oppnås det videre at. rivbrettet Also on the rough side surfaces, a corresponding adhesion and distribution effect is obtained for the water or the mortar. It has been shown in practice that in this way an influence on the already plastered surface can be avoided to a large extent, and that the work result is thus better with the tear board according to the invention. When the cells lying on the surface are opened, e.g. by milling or the like, there is no longer any film formed during casting on these side surfaces and thus no danger that the surface here is harder than in the interior of the tear plate. This in turn means that, after a certain period of use, no hard dents are formed which protrude from the side surfaces, and which can lead to the entrainment of mortar, i.e. an impact on the already plastered surface. At the same time, as a result of this milling away or similar of the side surfaces, it is ensured that all side surfaces will extend perpendicular to each other, whereby again the sanding of internal corners as well as the production of internal edges running exactly perpendicular to each other is facilitated. By this straightening of the short side surfaces, it is further achieved that. tear board
ikke må holdes på skrå for pussing av innvendige hjørner, must not be held at an angle for plastering internal corners,
hvorved der igjen kan unngås en beskadigelse på allerede ferdig pussede kanter. whereby damage to edges that have already been sanded can again be avoided.
Trekkene ifølge kravene 2 og 3 tillater en ru utformning The features according to claims 2 and 3 allow a rough design
av sideflatene av rivplaten når cellene er uåpnet. of the side surfaces of the tear plate when the cells are unopened.
Ved trekket ifølge krav 4 fås en styrt transport av sprutevann og på baksiden avsatt mørtel til siden, dvs. det oppnås at vannet resp. mørtelen renner av mot begge de lange sideflater og dermed mot det medtransporterte mørtelmateriale og ikke renner ned på resp. spruter bort på de allerede ferdige pussflater. Samtidig sikres det ved denne utformning at vannet resp. mørtelen oppløses i flere mindre deler. Ved at rennene og rillene strekker seg vinkelrett på lengdeaksen av rivflaten lettes også formgivningen av det ferdige rivbrett, slik at det for fremstilling klarer seg med en enkel, delt form. With the draft according to claim 4, a controlled transport of spray water and mortar deposited on the back to the side is achieved, i.e. it is achieved that the water resp. the mortar runs off towards both the long side surfaces and thus towards the transported mortar material and does not run down on the resp. splashes away on the already finished plaster surfaces. At the same time, this design ensures that the water or the mortar dissolves into several smaller parts. By the fact that the channels and grooves extend perpendicular to the longitudinal axis of the ripping surface, the shaping of the finished ripping board is also facilitated, so that it can be manufactured with a simple, split shape.
Ved trekkene i kravene 5 og 6 hver for seg eller til-sammen blir transporten av den mot de lange sideflater sterkt tiltagende vannmengde ytterligere forbedret. With the features in claims 5 and 6 individually or together, the transport of the strongly increasing amount of water towards the long side surfaces is further improved.
Ytterligere trekk og fordeler ved oppfinnelsen vil fremgå av den etterfølgende beskrivelse av et utførelseseksempel under hen-visning til tegningen. Fig. 1 er et grunnriss av et rivbrett ifølge oppfinnelsen'. Further features and advantages of the invention will be apparent from the subsequent description of an embodiment with reference to the drawing. Fig. 1 is a ground plan of a tearing board according to the invention.
Fig. 2 er et oppriss av rivbrettet på fig. 1. Fig. 2 is an elevation of the tear board in fig. 1.
Fig. 3 er et utsnitt av en sideflate av rivbrettet med cn overflate som er noe annerledes enn den som er vist på fig. 2. Fig. 3 is a section of a side surface of the tear board with a surface that is somewhat different from that shown in fig. 2.
Fig. 4 viser en ytterligere mulig utformning av sideflaten. Fig. 4 shows a further possible design of the side surface.
Et rivbrett ifølge oppfinnelsen består av en rivplate 1 og A shredding board according to the invention consists of a shredding plate 1 and
et håndtak 2 som er anordnet i rivbrettets vertikale langsgående midtplan og er utformet i ett stykke med platen 1. Rivplaten og håndtaket er fremstilt av en egnet.sterk skumplast, f.eks. et,hardt polyuretanskum, polyetenskum, ABS-skum eller lignende. Rivplaten 1 har to rettlinjede lange sideflater 3 og to likeledes rettlinjede korte sideflater 4, idet til hinannen støtende sideflater 3 og 4 danner en rett vinkel med hinannen. De korte' sideflater 4 gjøres rette ved bortfresing av de etter oppskummingen foreliggende sideflater 4' som danner en stumpvinklet trekant og på fig. 1 er vist stiplet. På denne måte blir samtidig de lukkede celler på de korte sideflater 4 åpnet, hvorved sideflatene 4 får en ru overflate, idet cellene åpnes resp. forbindes med atmosfæren når den ytre hud på det harde skum som danner seg på overflaten av de korte sideflater 4 ved oppskummingen, freses bort. a handle 2 which is arranged in the vertical longitudinal middle plane of the slatted board and is designed in one piece with the plate 1. The slatted plate and the handle are made of a suitable, strong foam plastic, e.g. a, hard polyurethane foam, polyethylene foam, ABS foam or similar. The tear plate 1 has two rectilinear long side surfaces 3 and two similarly rectilinear short side surfaces 4, the side surfaces 3 and 4 impinging on each other forming a right angle with each other. The short' side surfaces 4 are made straight by milling away the side surfaces 4' present after the foaming, which form an obtuse-angled triangle and in fig. 1 is shown dashed. In this way, at the same time, the closed cells on the short side surfaces 4 are opened, whereby the side surfaces 4 get a rough surface, as the cells are opened or is connected to the atmosphere when the outer skin of the hard foam that forms on the surface of the short side surfaces 4 during the foaming is milled away.
De langsgående sideflater 3 er ikke mekanisk bearbeidet, men har en ru overflate som følge av at de er forsynt med fine, vertikalt forløpende riller 5 (fig. 2) eller er forsynt med en nettlignende overflate 6, idet nettlinjene enten danner et rombemønster (se fig. 3) eller forløper vertikalt og horisontalt (se fig. 4). Når de korte sideflater ikke tildannes ved bortfresing eller lignende, men de opprinnelige sideflater 4<*> beholdes, vil også disse hensiktsmessig gis en lignende overflateform som de lange sideflater 3. The longitudinal side surfaces 3 are not mechanically processed, but have a rough surface as a result of the fact that they are provided with fine, vertically extending grooves 5 (fig. 2) or are provided with a net-like surface 6, the net lines either forming a rhombus pattern (see fig. 3) or runs vertically and horizontally (see fig. 4). When the short side surfaces are not formed by milling away or the like, but the original side surfaces 4<*> are retained, these will also suitably be given a similar surface shape as the long side surfaces 3.
Den beskrevne overflate av de lange sideflater 3 og eventuelt de korte sideflater 4 og spesielt den egenskap ved sideflatene at de ikke er nevneverdig hardere enn det indre parti av rivplaten 1, oppnås ved at den form som rivplaten 1 og håndtaket 2 skummes opp i, f.eks. ikke oppvarmes ytterligere i disse områder. The described surface of the long side surfaces 3 and possibly the short side surfaces 4 and in particular the property of the side surfaces that they are not significantly harder than the inner part of the tear plate 1, is achieved by foaming the shape in which the tear plate 1 and the handle 2, f .ex. not be heated further in these areas.
På oversiden av rivplaten 1 er der uttatt renner 8 som strekker seg ut fra rivplatens vertikale langsgående midtakse 7 og blir bredere og dypere mot de lange sideflater 3. Rennene 8 strekker seg dessuten omtrent vinkelrett på de lange sideflater 3. Overflaten av disse renner og de mellom rennene liggende steg 9 kan dessuten være utformet med i rennenes lengderetning forløpende fine riller 10 (se fig. 2) . Som følge av denne overflatestruktur av oversiden av rivplaten 1 fås der en behersket vanntransport mot sidene, dvs. at vann ikke vil sprute av fra rivbrettets overside mot bevegelsesretningen og ut på allerede pussede veggflater selv ved hurtige bevegelser av rivbrettet i sin lengderetning, idet vannet som følge av de fine riller 10 fastholdes bedre på overflaten;. On the upper side of the tear plate 1 there are grooves 8 which extend from the vertical longitudinal center axis 7 of the tear plate and become wider and deeper towards the long side surfaces 3. The grooves 8 also extend approximately perpendicular to the long side surfaces 3. The surface of these grooves and the step 9 lying between the channels can also be designed with fine grooves 10 running in the longitudinal direction of the channels (see fig. 2). As a result of this surface structure of the upper side of the tear board 1, a controlled transport of water towards the sides is obtained, i.e. that water will not splash off from the upper side of the tear board in the direction of movement and onto already plastered wall surfaces even during rapid movements of the tear board in its longitudinal direction, as the water which as a result of the fine grooves 10 are better retained on the surface;.
Rivflaten 11 kan på kjent måte, eventuelt i forbindelse med en cellestruktur med lukkede celler, ha åpnede celler som enten oppstår ved at cellene åpnes ved mekanisk bearbeidelse etter oppskummingen, eller ved at cellene åpner seg som følge av slitasje mot rivflaten når rivbrettet benyttes. The tear surface 11 can in a known manner, possibly in connection with a cell structure with closed cells, have opened cells which either occur when the cells are opened by mechanical processing after the foaming, or when the cells open as a result of wear against the tear surface when the tear board is used.
Sideflatene og^ oversiden sont er forsynt med riller 5 resp. nettlignende overflatemønstre 6, kan ifølge oppfinnelsen.utformes på The side surfaces and the upper side sont are provided with grooves 5 or net-like surface patterns 6, according to the invention, can be designed on
en hvilken som hels-t egnet måte»- og i denne forbindelse kan rennene 8 være utformet med skarpe kanter eller" være avrundet. Hvis der til oppskumming av rivbrettet anvendes en flerdelt form,l any suitable way" - and in this connection the channels 8 can be designed with sharp edges or "be rounded. If a multi-part form is used for foaming the grating board,
er det også mulig å la rennene 8 strekke seg stråleformig ut fra rivbrettets midtpunkt, slik at der finner sted en jevn vanntransport til samtlige sideflater 3,4. is it also possible to allow the channels 8 to extend radially from the midpoint of the rip board, so that a uniform water transport takes place to all side surfaces 3,4.
