Description

Opfindelsen angår et varmeisolerende profil, især til vindues- eller dørrammer, som nærmere angivet i krav l's indledning.The invention relates to a heat insulating profile, especially to window or door frames, as further specified in the preamble of claim 1.

Der kendes et varmeisolerende profil af denne art 5 (DE-A 29 11 832), hvor isolerlisten i det nederste område holdes mod de pågældende metalprofilstave af tilsvarende tvangsføringer.A heat-insulating profile of this kind is known (DE-A 29 11 832), in which the insulating strip in the lower area is held against the metal profile rods concerned by corresponding forced guides.

Den fra DE-A-2 911 832 kendte konstruktion har den ulempe, at mellemribberne og de gennemgående lister i prak-10 sis stemmer overens i henseende til deres anlæg mod isoler listen. Tolerancer i metalprofilribberne og også isolerlisten resulterer i, at enten mellemribberne eller metallisterne kommer til anlæg mod isolerlisten. På grund af på-formningen af metallisterne på isolerlisten opstår der i 15 tilfælde af metallisternes anlæg mod isolerlisten en tvang i isolerlisten, som deformeres, indtil også mellemribberne ligger an. Denne deformation kan naturligvis være forskellig ved de to profilsider, så at denne deformation fører til unøjagtigheder i det sammensatte profil, hvorved tole-20 rancerne i det samlede profil påvirkes. Hvis kun mellemribberne ligger an mod isolerlisten, opstår der mellem metallisterne og de tilhørende noter på isolerlisten et spillerum, som sørger for, at isolerlisten i dette område ikke ligger an mod metalprofilstavenes inderflade. Herved på-25 virkes de to metalprofilstaves planparallelitet. Metalpro-filstavene pendulerer om det øverste indspændingssted på isolerlisten, som dannes af metalribberne og mellemribberne. Da der på den bort fra mellemribberhe vendende side i dette tilfælde ikke fås en sikker forbindelse mellem iso-30 lerlisten og metalprofilstavene, er heller ikke en upåklagelig kraftafgrening over forbindelsesområdet mere mulig.The construction known from DE-A-2 911 832 has the disadvantage that the intermediate ribs and the through moldings in practice correspond with respect to their insulation against the insulation list. Tolerances in the metal profile ribs and also the insulating strip result in either the middle ribs or the metal strips coming into contact with the insulating strip. Due to the molding of the metal strips on the insulating strip, in 15 cases the abutment of the metal strips against the insulating strip causes a forcing in the insulating strip, which deforms until the middle ribs also touch. This deformation can, of course, be different at the two profile sides so that this deformation leads to inaccuracies in the composite profile, thereby affecting the tolerances in the overall profile. If only the middle ribs abut the insulating strip, there is a clearance between the metal strips and the associated notes on the insulating strip, which ensures that the insulating strip in this area does not touch the inner surface of the metal profile rods. This affects the plane parallelity of the two metal profile rods. The metal profile file bars pivot about the top clamping point of the insulating strip formed by the metal ribs and the middle ribs. In this case, since the insulating side facing away from the middle ribs does not provide a safe connection between the insulating strip and the metal profile bars, an impeccable branching of the power over the connection area is also not possible.

Formålet med opfindelsen er at anvise et varmeisolerende sammensat profil af den angivne art med en sådan udformning, at der sikres en nøjagtig stillingsstabilitet af 35 metalprofilstavene og isolerlisten trods fremstillingstolerancerne og -unøjagtighederne i de konstruktionsdele, som udgør hele profilet.The object of the invention is to provide a heat-insulating composite profile of the type specified in such a manner as to ensure an accurate positioning stability of the metal profile rods and the insulating strip despite the manufacturing tolerances and inaccuracies in the structural parts which make up the entire profile.

l's kendetegnende del angivne konstruktion.1's characteristic part.

Ved konstruktionen ifølge opfindelsen sikres det, at alle randlister med deres sidebegrænsningsflader kommer i sikkert anlæg mod metalprofilstavens indervæg. I denne 5. forbindelse er spalten mellem optagenotens notbund og randlisten meget vigtig, fordi der ved hjælp af denne spalte i alle tilfælde garanteres et anlæg af randlisterne mod mellemribberne, og fordi randlisterne på grund af en ved inderribbens svingning og kolddeformation optrædende kraft 10 presses mod metalprofilstavens inderflade.In the construction according to the invention, it is ensured that all edge strips with their lateral boundary surfaces come in a secure abutment against the inner wall of the metal profile rod. In this 5th connection, the gap between the score sheet's groove bottom and the edge strip is very important because by means of this gap, in all cases, an abutment of the edge strips against the middle ribs is guaranteed and because the edge strips due to the force of the inner rib swing and cold deformation are pressed against the inner profile of the metal profile rod.

Den vertikale sammenspænding mellem metalprofilstavene og isolerlisten sker ligeledes på grund af de ikke-deformerbare mellemribber, som griber ind i noterne i isolerlisten, og på grund af de deformerbare gennemgående lister 15 på metalprofilstavene. Da kun de på indersiden af metalprof ilstavene anbragte gennemgående lister deformeres, holdes metalprofilstavenes synlige flader parallelt med hinanden. Også en forskydning i højden forebygges.The vertical tension between the metal profile bars and the insulating strip also occurs because of the non-deformable intermediate ribs which engage the grooves in the insulating strip and because of the deformable through strips 15 on the metal profile strips. Since only the through moldings on the inside of the metal profile bars are deformed, the visible surfaces of the metal profile bars are held parallel to each other. Also, an increase in height is prevented.

Til forøgelse af isolervirkningen under bibeholdelse 20 af en høj stabilitet af isolerlisten findes der hensigtsmæssigt inde i isolerlisten to eller fire hulrum, der tjener som luftkamre.To enhance the insulating effect while maintaining a high stability of the insulating strip, there are suitably within the insulating strip two or four cavities serving as air chambers.

Således opnås der en fast forbindelse mellem isolerlisten og metalprofilstavene under overholdelse af en nøj-25 agtig totalprofildybde. De konstruktionsdele, som danner hele profilet, sammenspændes med hinanden både i vertikal og i horisontal retning,idet der på grund af det til at begynde med eksisterende spillerum mellem bestanddelene også opnås, at selv større fremstillingstolerancer uden 30 videre udlignes.Thus, a firm connection is obtained between the insulating strip and the metal profile rods while maintaining an accurate total profile depth. The structural parts which form the entire profile are clamped together in both vertical and horizontal directions, because of the fact that, initially with the existing clearance between the components, it is also achieved that even greater manufacturing tolerances are further equalized.

Ved en fordelagtig udførelsesform ifølge opfindelsen har isolerlisten i alle hjørneområder landlister, som med deres sidebegrænsningsflader ligger sikkert an mod den indre væg af metalprofilstavene.In an advantageous embodiment of the invention, the insulating strip in all corner areas has land strips which, with their lateral boundary surfaces, are securely in contact with the inner wall of the metal profile bars.

3 I de fire hjørneområder af isolerlisten fås der således en sikker sammenspænding mellem isolerlisten og metalpro-filstavene, så at der slås en bro over fremstillingstolerancerne og -unøjagtighederne hos de konstruktionsdele, 5 som danner det samlede profil.3 Thus, in the four corner regions of the insulating molding, a secure tension is obtained between the insulating molding and the metal profile rods, so as to bridge the manufacturing tolerances and inaccuracies of the structural parts 5 which form the overall profile.
