Description

Vippeport. Swing gate.

Foreliggende oppfinnelse angår en vippeport, særlig garasjeport, med et dorblad som på hver side bæres av en opphengningsanordning som omfatter dels en svingearm, hvis ytre ende er leddfordun-det med et beslag på dorbladets nedre halvdel og som mellom sine ender er svingbart lagret på et ved døråpningens side festet beslag og hvis indre ende er påvirket av en trekkfjær som soker å svinge svingearmen i dorens åpningsretning, samt dels en stottearm, hvis indre ende er leddforbundet med svingearmen på et sted mellom dens svingeakse og dens ytre ende og hvis ytre ende er anordnet for sammen med svingearmen å bære dorbladet i dettes oppsvingede stilling. The present invention relates to an up-and-over door, in particular a garage door, with a door leaf which is carried on each side by a suspension device which partly comprises a swing arm, the outer end of which is articulated with a fitting on the lower half of the door leaf and which between its ends is pivotally supported on a on the side of the door opening, fittings fixed and whose inner end is influenced by a tension spring which seeks to swing the swing arm in the opening direction of the door, as well as partly a support arm, whose inner end is articulated with the swing arm at a place between its axis of swing and its outer end and whose outer end is arranged to, together with the swing arm, carry the mandrel blade in its upturned position.

Det fins allerede et stort antall forskjellige utfbrelser av opphengningsanordningen for slike vippeporter. Et eksempel er vist i tysk patentskrift 942.966. There are already a large number of different versions of the suspension device for such swing gates. An example is shown in German patent specification 942,966.

En ulempe ved de hittil kjente enkle utforelser av slike opphengningsanordninger er at det kreves forholdsvis stor håndkraft for å svinge opp henholdsvis svinge ned dorbladet. Særlig for kvinner og barn kan dette innebære betydelige vanskeligheter . A disadvantage of the previously known simple designs of such suspension devices is that a relatively large hand force is required to swing up and down respectively the mandrel blade. For women and children in particular, this can mean significant difficulties.

Formålet med foreliggende oppfinnelse er med enkle midler The purpose of the present invention is to use simple means

å forbedre angjeldende opphengningsanordning, slik at den praktisk talt i alle stillinger er avbalansert, dvs. slik at det kreves en forholdsvis liten kraft for å svinge dorbladet i onsket retning. to improve the relevant suspension device, so that it is practically balanced in all positions, i.e. so that a relatively small force is required to swing the mandrel blade in the desired direction.

Dette oppnås ifolge oppfinnelsen med en vippeport av den beskrevne art, som ifolge oppfinnelsen er kjennetegnet ved at stottearmen mellom sine ender hviler forskyvbart på et stottelager som er festet på siden av doråpningen, idet stottearmens ytre ende er fritt forskyvbar langs en styring på dorbladets ovre halvdel, eller er leddforbundet med et beslag på dorbladets ovre halvdel og at stdttearmen består av teleskopisk forlengbare deler. Ved hjelp av denne anordning er det mulig å oppnå slike vektarmer i forhold til stottelageret og svingearmens svingeakse, at momentet av dorbladets vekt praktisk talt helt ut balanseres av momentet av fjærens svingekraft om svingeaksen. This is achieved according to the invention with a tilting gate of the type described, which according to the invention is characterized by the fact that the support arm rests displaceably between its ends on a support bearing which is attached to the side of the mandrel opening, the outer end of the support arm being freely displaceable along a guide on the upper half of the mandrel blade , or is articulated with a fitting on the upper half of the mandrel blade and that the support arm consists of telescopically extendable parts. With the help of this device, it is possible to achieve such weight arms in relation to the support bearing and the swing axis of the swing arm, that the moment of the mandrel's weight is practically completely balanced by the moment of the spring's swing force about the swing axis.

I sin enkleste og billigste utfdrelse er stottearmens ytre ende glidbart lagret i en styring på dorbladet. Som et alternativ kan imidlertid stottearmens ytre ende være leddforbundet med dorbladet og stottearmen består da av to teleskopisk forlengbare deler. In its simplest and cheapest version, the outer end of the support arm is slidably stored in a guide on the mandrel blade. As an alternative, however, the outer end of the support arm can be articulated with the mandrel blade and the support arm then consists of two telescopically extendable parts.

To hensiktsmessige utforelsesformer av oppfinnelsen er vist som eksempel på tegningen, hvor fig. 1 viser en enkel utfdrelse, hvor dorbladet er vist med heltrukne linjer i oppsvinget stilling, fig. 2 viser en modifisert utfdrelse, hvor stottearmens ytre ende be-veger seg langs en noe flatere bane enn på fig. 1, og fig. 3 viser et stottelager i form av en sportrinse. Two suitable embodiments of the invention are shown as examples in the drawing, where fig. 1 shows a simple version, where the mandrel blade is shown with solid lines in an upturned position, fig. 2 shows a modified version, where the outer end of the support arm moves along a somewhat flatter path than in fig. 1, and fig. 3 shows a support bearing in the form of a sports pulley.

På fig. 1 og 2 er vist en doråpning som på begge sider er forsynt med en opphengningsanordning for et oppsvingbart dorblad 10. Bare opphengningsanordningen på den ene side skal beskrives i det fdlgende. In fig. 1 and 2 show a door opening which is provided on both sides with a suspension device for a hinged door leaf 10. Only the suspension device on one side will be described in the following.

Til dorbladets nedre halvdel er festet et beslag 11 og på dbråpningens side er festet et beslag 12. En svingearm 13 er mellom sine ender svingbart lagret om en aksel 14 på beslaget 12. Svingearmens ytre ende er ved 15 leddforbundet med beslaget 11 og svingearmens indre ende er ved 16 påvirket av en trekkf jær 17 som soker å svinge doren opp. A fitting 11 is attached to the lower half of the mandrel blade and a fitting 12 is attached to the side of the opening. A swing arm 13 is between its ends pivotably mounted about an axle 14 on the fitting 12. The outer end of the swing arm is articulated at 15 with the fitting 11 and the inner end of the swing arm is at 16 affected by a tension spring 17 which seeks to swing the mandrel up.

Mellom svingearmens svingeaksel 14 og svingearmens ytre leddpunkt foreligger et beslag 18 som danner den svingbare forbindelse for den ene ende av en stdttearm 19. Between the swing arm's pivot shaft 14 and the swing arm's outer joint point there is a fitting 18 which forms the pivotable connection for one end of a support arm 19.

Beslaget 18 ligger hensiktsmessig tilnærmet midt mellom punktene 14 og 15, men i denne foretrukne viste utforelsesform ligger beslaget 18 noe nærmere punktet 14 enn punktet 15-Fitting 18 is suitably located approximately in the middle between points 14 and 15, but in this preferred embodiment shown, fitting 18 is somewhat closer to point 14 than to point 15-

Stottearmen 19 hviler forskyvbart på et stottelager i form av en sportrinse 20 som bæres av en konsoll 21 festet på siden av dør-åpningen . The support arm 19 rests displaceably on a support bearing in the form of a pulley 20 which is carried by a console 21 attached to the side of the door opening.

Stottearmens 19 ytre ende 22 ligger fritt forskyvbart an mot en styring 23 på dorbladets nedre halvdel. I snitt har styringen hensiktsmessig U-form. Under dorens svingebevegelse kan stottearmens ytre ende 22 gli fritt langs styringen 23. The outer end 22 of the support arm 19 lies freely displaceably against a guide 23 on the lower half of the mandrel blade. On average, the steering has an appropriate U-shape. During the pivoting movement of the mandrel, the support arm's outer end 22 can slide freely along the guide 23.

Som et alternativ kan stottearmens ytre ende 22 være leddforbundet med et beslag på dorbladet, men i dette tilfelle må stottearmen bestå av to teleskopisk forlengbare deler. As an alternative, the support arm's outer end 22 can be articulated with a fitting on the mandrel blade, but in this case the support arm must consist of two telescopically extendable parts.

Ved dorbladets svingebevegelse fra den viste, hovedsakelig horisontale stilling folger stottearmens ytre ende 22 den med en brutt linje viste bue 24 og svingearmens ytre ende 15 folger sirkelbuen 25. Stottearmens indre leddpunkt 18 folger den med en brutt linje viste sirkelbue 26. During the pivoting movement of the mandrel blade from the shown, mainly horizontal position, the outer end 22 of the support arm follows the arc 24 shown with a broken line and the outer end 15 of the swing arm follows the circular arc 25. The inner joint point 18 of the support arm follows the circular arc 26 shown with a broken line.

I den viste oppsvingte stilling er vektarmen mellom punktet 18 og stottelageret forholdsvis liten, hvilket medforer et forholdsvis lite moment som praktisk talt utbalanseres av momentet av fjæren 1,7. Når doren svinges ned til f.eks. den med strek-prikk-trukne linjer viste mellomstilling, vil vektarmen mellom punktene 18 og 20 tilta med derav folgende stdrre moment. Fjæren 17 er imidlertid da spent ut og har en storre trekkraft, hvilket dessuten virker på en stdrre momentarm til svingeakselen 14. Det av fjæren bevirkede moment utbalanserer praktisk talt helt momentet av dorbladet. In the shown raised position, the weight arm between the point 18 and the support bearing is relatively small, which results in a relatively small moment which is practically balanced by the moment of the spring 1.7. When the mandrel is swung down to e.g. the intermediate position shown with dash-dotted lines, the weight arm between points 18 and 20 will increase with the consequent greater torque. However, the spring 17 is then stretched out and has a greater pulling force, which also acts on a stronger torque arm for the swing shaft 14. The torque caused by the spring practically balances out the torque of the mandrel blade.

For å muliggjdre justering av dorbladets hdydestilling i dorbladets oppsvingte stilling er stottelagerets beslag 21 hensiktsmessig innstillbart i hoyderétning. In order to enable adjustment of the door blade's height position in the door blade's upturned position, the support bearing's fitting 21 is appropriately adjustable in height.

Utforelsen på fig. 2 skiller seg fra den på fig. 1 viste utfdrelse ved at stottearmens 19 indre ende er utformet med en gaffel 27 som griper over en boyle 28 festet på svingearmen. Mellom gaffelens ben foreligger en aksel 29 som danner et ledd for stottearmens svingebevegelse. Akselen er forskyvbar mellom to sluttstillinger som bestem- The embodiment in fig. 2 differs from that of fig. 1 showed an extension in that the inner end of the support arm 19 is designed with a fork 27 that grips over a bolt 28 attached to the swing arm. Between the legs of the fork there is an axle 29 which forms a link for the pivoting movement of the support arm. The shaft is displaceable between two end positions which determine

På fig. 2 foréligger dessuten et mandvreringsledd 30 som In fig. 2 there is also a mandvrring link 30 which

This interpretation can be used when the ceiling in e.g. the garage is immediately above the upper edge of the opening.
