Description

Oppfinnelsen angår en isolerende profil, især for vindus- eller dørrammer ifølge kravenes innledning. The invention relates to an insulating profile, especially for window or door frames according to the introduction of the requirements.

Et varmehemmende sammensatt profil av denne type er kjent fra DE 2 911 832 hvor isoleringslisten holdes i det A heat-inhibiting composite profile of this type is known from DE 2 911 832 where the insulating strip is held in the

nedre område ved tilsvarende tvangsføringer på vedkommende metallprofiler. I praksis har det imidlertid vist at metall-prof ilene i det nedre område, især ved de spor som er innlagt i isoleringslisten for opptak av metallprofilenes tilsvarende mellomsteg, dvs. i tvangsføringenes område, på grunn av fremstillingstoleranser, hhv. fremstillingsunøyaktigheter ikke i tilsvarende grad holdes av isoleringslisten. Dette fører til ikke tilfredsstillende sammensatte profiler med hensyn til målholdighet og parallellitet for metallprofilene i forhold til hverandre. lower area with corresponding forced guides on the relevant metal profiles. In practice, however, it has been shown that the metal profiles in the lower area, especially at the tracks that are laid in the insulation strip for recording the corresponding intermediate steps of the metal profiles, i.e. in the area of the forced guides, due to manufacturing tolerances, or manufacturing inaccuracies are not contained to the same extent by the insulation list. This leads to unsatisfactory composite profiles with regard to dimensional accuracy and parallelism for the metal profiles in relation to each other.

Oppfinnelsen tar sikte på å løse den oppgave å frem-bringe et varmehemmende sammensatt profil av den innlednings-vis nevnte type på en slik måte at metallprofilenes og isoleringslistenes nøyaktige stillingsstabilitet sikres til tross for fremstillingstoleranser og fremstillingsunøyaktig-heter ved de deler som danner det sammensatte profil. The invention aims to solve the task of producing a heat-inhibiting composite profile of the type mentioned at the outset in such a way that the exact positional stability of the metal profiles and insulation strips is ensured despite manufacturing tolerances and manufacturing inaccuracies in the parts that form the composite profile .

Denne oppgave løses med profilet ifølge oppfinnelsen med de i kravenes karakteriserende deier anførte trekk. This task is solved with the profile according to the invention with the features listed in the characterization of the requirements.

Utførelser av det isolerende profil ifølge oppfinnelsen er vist på tegningen hvor figur 1 viser et tverrsnitt av et sammensatt profil i ennå ikke fullstendig sammensatt tilstand, figur 2 viser det sammensatte profil på figur 1 i sammensatt tilstand, figur 3 viser en modifikasjon av utførelsen på figur 1 og 2 og figur 4 viser et snitt av en ramme og en karm som er fremstilt av sammensatte profiler ifølge oppfinnelsen. Versions of the insulating profile according to the invention are shown in the drawing, where figure 1 shows a cross-section of a composite profile in a not yet fully assembled state, figure 2 shows the composite profile in figure 1 in the assembled state, figure 3 shows a modification of the embodiment in figure 1 and 2 and figure 4 show a section of a frame and a frame which are produced from composite profiles according to the invention.

Det sammensatte profil består av metallprofiler 1, 2, la, 2a, og en isoleringslist 3 av profilert, formbestandig plast. Isoleringslisten ifølge utførelsen på figur 1 og 2 The composite profile consists of metal profiles 1, 2, 1a, 2a, and an insulating strip 3 of profiled, shape-resistant plastic. The insulation strip according to the design in figures 1 and 2

har fire hulrom 4 som er utformet som luftkamre idet stegene mellom hulrommene 4 er utformet som diagonaler 5 i isoleringslisten 3. has four cavities 4 which are designed as air chambers, as the steps between the cavities 4 are designed as diagonals 5 in the insulation strip 3.

Ved utførelsen på figur 4 har isoleringslisten 3 to hulrom 4. In the embodiment in Figure 4, the insulating strip 3 has two cavities 4.

På profilene 1, 2, la, 2a er i det øvre område utenfor den isoleringslist 3 som forbinder dem, anordnet overfor hverandre, i utgangsstillingen horisontalt liggende, gjennomgående lister 6, ;7 i hvis underside gjennomgående kammer 8 er anordnet. En tilsvarende fordypning i isoleringslisten 3 er til-ordnet kammen 8. I tillegg har isoleringslisten 3 på de sider som vender mot metallprofilene 1, 2, et på skrå oppad mot dens indre rettet spor 10, 11. <:>I disse spor griper metallprofilenes mellomsteg 12, 13 inn. De skrå spors 10, 11 lysåpning er vesentlig større enn mellomstegenes 12, 13 tykkelse. Hvert mellomsteg 12, 13 har en gjennomgående rille 14 på overgangs-stedet til den tilhørende metallprofil 1, 2, la, 2a, i hvilke en kantlist 15 på isoleringslisten 3 griper inn med spissen. Videre har isoleringslisten 3 i midten på undersiden en nese 16 som ved bruk av det sammensatte profil som vindusramme tje-ner som anslag for den tilisvarend<e> karm. On the profiles 1, 2, la, 2a, in the upper area outside the insulating strip 3 which connects them, arranged opposite each other, in the initial position lying horizontally, continuous strips 6, 7 in the underside of which a continuous chamber 8 is arranged. A corresponding recess in the insulating strip 3 is assigned to the comb 8. In addition, the insulating strip 3 on the sides facing the metal profiles 1, 2, has a groove 10, 11 directed obliquely upwards towards its interior. <:>In these grooves, the metal profiles grip intermediate step 12, 13 in. The light opening of the inclined grooves 10, 11 is significantly larger than the thickness of the intermediate steps 12, 13. Each intermediate step 12, 13 has a continuous groove 14 at the transition point to the associated metal profile 1, 2, la, 2a, in which an edge strip 15 on the insulation strip 3 engages with the tip. Furthermore, the insulating strip 3 in the middle on the underside has a nose 16 which, when the composite profile is used as a window frame, serves as a stop for the corresponding frame.

Ved utførelsen på figur 1 og 2 er på hver metallprofil 1, 2 en nedre hakeformet list 17, 18 anordnet overfor de øvre lister 6, ;7. Hver list 17, 18 griper allerede i ikke innspent tilstand, slik det er vist på figur 1, inn i et tilsvarende spor 19 i isoleringslisten 3. Listenes 17, 18 steg 20 er skråstilt nedover i en vinkel på ca. 10° i forhold til metallprofilets tverrplan 21, mens vinkelen mellom innsiden av listens 17, 18 hake 22 og metallprofilets parallellplan 23, er ca. 20°. Tilsvarende er også vinkelen mellom sporets 19 sidevegger og det parallelle plan 23, ca. 20°. Herved er både overgangen fra innsiden av listens 17, 18 hake 22 til innsiden av listens 17, 18 steg 20, og også overgangen fra sporets 19 sidevegg som ligger tettest ved det tilhørende metallprofil, til isoleringslistens 3 underside, utformet avrundet. Likeledes avrundet er også overgangene utført fra sporets bunn til sideveggene. In the embodiment in Figures 1 and 2, on each metal profile 1, 2 a lower chin-shaped strip 17, 18 is arranged opposite the upper strips 6, 7. Each strip 17, 18 already engages in a non-tensioned state, as shown in Figure 1, into a corresponding groove 19 in the insulation strip 3. The steps 20 of the strips 17, 18 are inclined downwards at an angle of approx. 10° in relation to the metal profile's transverse plane 21, while the angle between the inside of the strip's 17, 18 hook 22 and the metal profile's parallel plane 23 is approx. 20°. Correspondingly, the angle between the side walls of the track 19 and the parallel plane 23 is also approx. 20°. Hereby, both the transition from the inside of the strip 17, 18 hook 22 to the inside of the strip 17, 18 step 20, and also the transition from the side wall of the track 19 which is closest to the associated metal profile, to the underside of the insulation strip 3, is designed rounded. The transitions from the bottom of the track to the side walls are also rounded.

I tillegg har overgangen fra oversiden av listens 17, 18 hake 22 til baksiden, en avrunding. Også overgangen fra utsiden av listens 17, 18 steg 20 til den tilhørende profil er utformet avrundet.! Tykkelsen av.listens 17, 18 hake 22 tilsvarer tykkelsen avj listens 17, 18 steg 20. I innsiden av listens 17, 18 steg 20 er på forbindelsesstedet med den tilhørende metallprofil innlagt en gjennomgående rille 24 som bøyeanvisning. Den ende av listens 17, 18 hake 22 som griper inn i sporets 19 sidevegg er utført spiss. In addition, the transition from the upper side of the list 17, 18 to the notch 22 to the back has a rounding. Also the transition from the outside of the strip 17, 18 step 20 to the associated profile is designed rounded.! The thickness of the strip 17, 18 hook 22 corresponds to the thickness of the strip 17, 18 step 20. In the inside of the strip 17, 18 step 20, at the point of connection with the associated metal profile, a continuous groove 24 is inserted as a bending instruction. The end of the strip 17, 18 hook 22 which engages in the side wall of the groove 19 is made pointed.

Ved fremstillingen av det sammensatte profil* ifølge figur 1 og 2 nedtrykkes samtidig eller etter hverandre på- den ene side de øvre lister 6, 7 fra deres horisontale, på figur 1 viste stilling, slik at kammene 8 med fordypningene 9 kommer til inngrep i isoleringslisten 3 og hvor på den annen side de nedre hakeformede lister 17, 18 trekkes opp fra deres på skrå nedad rettede stilling til en tilnærmet horisontal stilling, slik at listenes 17, 18 haker 22 presser isoleringslisten fast mot metallprofilens 1, 2 tilsvarende indre vegg 26. In the production of the composite profile* according to Figures 1 and 2, the upper strips 6, 7 are pressed down simultaneously or one after the other on one side from their horizontal position shown in Figure 1, so that the ridges 8 with the recesses 9 engage in the insulation strip 3 and where, on the other hand, the lower hook-shaped strips 17, 18 are pulled up from their inclined downwards position to an approximately horizontal position, so that the strips 17, 18's hooks 22 press the insulation strip firmly against the corresponding inner wall 26 of the metal profile 1, 2.

Ved deformasjonen av listene 6, 7 fra den på figur 1 viste stilling til den på figur 2 viste stilling, utføres en svingning av listene 6,7 omkring aksen A. Svingningen av de hakeformede lister 17, 18 foregår omkring aksen B. Isoleringslistens 3 kantelister 15, 25 legges kraftoverførende fast i den på figur 2 viste sluttstilling med deres sideveis begren-sningsflate 15a, 25a mot metallprofilens indre vegg 26. During the deformation of the strips 6, 7 from the position shown in figure 1 to the position shown in figure 2, a swing of the strips 6, 7 is carried out around axis A. The swing of the hook-shaped strips 17, 18 takes place around axis B. The 3 edge strips of the insulation strip 15, 25 are fixed in the final position shown in Figure 2 with their lateral limiting surface 15a, 25a against the inner wall 26 of the metal profile.

Ved dreiningen av listene 6, 7 trykkes også isoleringslisten 3 fast mot mellomstegene 12., 13 slik at det i tillegg til en kraftoverføring også oppnås en formoverensstemmeIse og at det oppnås en vedvarende, uforanderlig forbindelse mellom de enkelte deler som danner det sammensatte profil. During the rotation of the strips 6, 7, the insulating strip 3 is also pressed firmly against the intermediate steps 12, 13 so that in addition to a power transfer, a shape consistency is also achieved and that a persistent, unchanging connection is achieved between the individual parts that form the composite profile.

Ved utførelsen på figur 3 er istedenfor de hakeformede lister 17, 18 anordnet om en akse B svingbare og halvt defor-merbare steg 30 som begrenser et opptaksspor 28 på innsiden. In the embodiment in Figure 3, instead of the hook-shaped strips 17, 18, pivotable and semi-deformable steps 30 are arranged around an axis B which limit a recording groove 28 on the inside.

I opptakssporet 28 innføres en kantlist 25 på isoleringslisten 3. Stegets 30 utgangsstilling er på figur 3 tegnet med helt uttrukne linjer. Stegets 30 endestilling er tegnet stiplet. In the recording groove 28, an edge strip 25 is introduced on the insulation strip 3. The starting position of the step 30 is shown in figure 3 with fully extended lines. The end position of the step 30 is shown dotted.

Steget 30 har i sin frie endes område en fremspringende kam 27 på den side som vender mot kantlisten 25. The step 30 has, in the area of its free end, a projecting comb 27 on the side facing the edge strip 25.

Opptakssporets 28 bunn 29 strekker seg på tvers av metallprofilets 12 indre vegg 26. Også etter utformingen av steget 30 foreligger en klaring mellom kantlisten 25 og bunnen. The bottom 29 of the receiving groove 28 extends across the inner wall 26 of the metal profile 12. Even after the design of the step 30, there is a clearance between the edge strip 25 and the bottom.

De krefter med hvilke kantlistene 25 og også kantlistene 15 presses mot metallprofilenes indre vegg 26 er antydet med piler, betegnet med F. The forces with which the edge strips 25 and also the edge strips 15 are pressed against the inner wall 26 of the metal profiles are indicated by arrows, denoted by F.
