Abstract

The invention relates to a method of improving the heat insulation on frames (1) which are made up of heat-insulated composite profiles (2) for windows, doors or the like, the composite profiles (2) comprising two metal profiles (3, 4) which are held at a distance from one another and are connected to one another, with the formation of at least one inner chamber (6), via at least two mutually parallel insulating webs (5) arranged in grooves of the metal profiles (3, 4), and each inner chamber (6) exhibiting a heat-insulation material (7). In order to avoid the former difficulties, the invention proposes that the heat-insulating material (7), in particular in the form of small particles (8), be introduced at at least one point (9) into each inner chamber (6) of the composite profiles (2) only when the frame (1) has been ready-assembled. <IMAGE>

Description

Oppfinnelsen angår en fremgangsmåte til forbedring av varmeisolasjonen ved rammer av varmeisolerte profiler for vinduer, dører og lignende, som angitt i innledningen til krav 1. Det finnes tallrike forslag på hvorledes varmeisolasjonen av profiler og dermed varmeisolasjonen av rammer som settes sammen av disse. Dette blir særlig oppnådd ved at varmeisolerende materiale innføres i hulrommene i profilene slik at varmestråling og varmekonveksjon reduseres (se DE-OS 3 440 710). The invention relates to a method for improving the thermal insulation of frames of heat-insulated profiles for windows, doors and the like, as stated in the introduction to claim 1. There are numerous proposals for how the thermal insulation of profiles and thus the thermal insulation of frames assembled from these. This is particularly achieved by introducing heat-insulating material into the cavities in the profiles so that heat radiation and heat convection are reduced (see DE-OS 3 440 710).

Som en illustrasjon av kjent teknikk på området skal det vises til NO 109126, NO B 161187, SE B 409220, EP A3 0131279, samt tidligere inngitte, men ved foreliggende søknads inngivelse, ikke allment tilgjengelig, EP Al 0560193. As an illustration of prior art in the area, reference should be made to NO 109126, NO B 161187, SE B 409220, EP A3 0131279, as well as previously submitted, but at the time of the submission of the present application, not generally available, EP Al 0560193.

Ved overflatebehandling av profiler som er utstyrt på denne måte står man overfor vanskeligheter eller fremstilling av tilskårne deler av slik utstyrte profiler kan vise seg vanskelig. Formålet med oppfinnelsen er derfor å forenkle fremstillingsmåten for rammer der de nevnte vanskeligheter unngås. When surface treatment of profiles equipped in this way, one is faced with difficulties or the production of cut parts of profiles equipped in this way can prove difficult. The purpose of the invention is therefore to simplify the manufacturing method for frames where the aforementioned difficulties are avoided.

Formålet blir ifølge foreliggende oppfinnelse oppfylt ved en fremgangsmåte av den innledningsvis nevnte art hvis karak-teristiske trekk fremgår av krav 1. Ytterligere trekk ved fremgangsmåten fremgår av de øvrige uselvstendige kravene. According to the present invention, the purpose is fulfilled by a method of the kind mentioned at the outset, the characteristic features of which appear in claim 1. Further features of the method appear in the other independent claims.

Dermed er det tilveiebrakt en enkel og billig fremstillings-måte samtidig med at de tidligere vanskeligheter når det gjelder overflatebearbeiding og skjæring av profilene er omgått. Thus, a simple and cheap manufacturing method has been provided, at the same time that the previous difficulties in terms of surface treatment and cutting of the profiles have been bypassed.

Det kan særlig anbefales å innføre det varmeisolerende materiale på høyst ett sted av rammen. It is particularly recommended to introduce the heat-insulating material at most in one place of the frame.

I henhold til en foretrukket utførelsesform blir det varmeisolerende materiale innført i form av små partikler der det dreier seg om partikler, særlig som granulat av organiske stoffer eller stof fblandinger, fortrinnsvis silikater, metalloksyder eller lignende, eller om kuler av oppskummet kunststoff som polyamid, polyetylen, polystyrol, polyuretan eller lignende, her oppnås ytterligere den store fordel at problemer med innføringen av varmeisolerende materiale unngås fordi det ikke lenger er nødvendig å ha forråd av varmeisolerende materiale for forskjellige tverrsnitt av hulrommet . According to a preferred embodiment, the heat-insulating material is introduced in the form of small particles, where these are particles, in particular as granules of organic substances or substance mixtures, preferably silicates, metal oxides or the like, or balls of foamed plastic such as polyamide, polyethylene .

Innføringen av det varmeisolerende materiale foregår fortrinnsvis ved innfylling eller ved at materialet blåses inn og/eller suges inn fra en forrådsbeholder. I henhold til en utførelsesform for oppfinnelsen er det da i tillegg til minst en luftinnløpsåpning anordnet minst en luftutløpsåpning som er dekket med en sil eller lignende som holder partikler tilbake. For å forbedre fyllingsgraden under fylleforløpet blir rammen satt i svingninger fortrinnsvis mekanisk, elektrisk eller med ultralyd. The introduction of the heat-insulating material takes place preferably by filling or by the material being blown in and/or sucked in from a storage container. According to an embodiment of the invention, in addition to at least one air inlet opening, at least one air outlet opening is arranged which is covered with a strainer or the like that retains particles. To improve the degree of filling during the filling process, the frame is set in oscillations preferably mechanically, electrically or with ultrasound.

Oppfinnelsen blir nærmere forklart under henvisning til utførelseseksempler som er vist på tegningene og der The invention is explained in more detail with reference to embodiment examples shown in the drawings and therein

Fig. 1 viser skjematisk en varmeisolert ramme 1 for vinduer, dører eller lignende av profiler 2 hvis profiltverrsnitt er vist på fig. 1. Det varmeisolerte profil 2 består f.eks. av to aluminiumprofiler 3, 4 som holdes i avstand fra hverandre og er forbundet med hverandre ved hjelp av minst to iso-leringssteg 5 som løper parallelt med hverandre og er innført i spor i metallprofilene 3, 4. Her dannes det da ett eller flere hulrom 6 (sonene for varmeisolasjon er antydet stiplet). Fig. 1 schematically shows a heat-insulated frame 1 for windows, doors or the like made of profiles 2 whose profile cross-section is shown in fig. 1. The heat-insulated profile 2 consists of e.g. of two aluminum profiles 3, 4 which are kept at a distance from each other and are connected to each other by means of at least two insulating steps 5 which run parallel to each other and are inserted into grooves in the metal profiles 3, 4. Here one or more cavities are then formed 6 (the zones for thermal insulation are indicated dotted).

Til forbedring av varmeisolasjonen blir varmeisolerende materiale 7 innført i det indre hulrom 6. Dette foregår ved at varmeisolerende materiale 7 i form av kuler 8 innføres i den ferdig sammensatte ramme 1 på minst ett sted som er betegnet med henvisningstallet 9 i hulrommet 6 i profilet 2. To improve the heat insulation, heat-insulating material 7 is introduced into the inner cavity 6. This takes place by introducing heat-insulating material 7 in the form of balls 8 into the finished frame 1 in at least one place designated by the reference number 9 in the cavity 6 in the profile 2 .

På fig. 3 og 4 er videre innblåsning resp. innsugning av kuler 8 av et kunststoff som polyamid, polyetylen, polystyrol, polyuretan eller av organiske granulater fra en forrådsbeholder 10 vist. Her er det i tillegg til minst en luftinnløpsåpning 9 anordnet minst en luftutløpsåpning 11 som er dekket med en sil 12 eller lignende for å holde tilbake partikler 8. In fig. 3 and 4 are further blowing in resp. suction of balls 8 of a synthetic material such as polyamide, polyethylene, polystyrene, polyurethane or of organic granules from a storage container 10 shown. Here, in addition to at least one air inlet opening 9, at least one air outlet opening 11 is arranged which is covered with a strainer 12 or the like to retain particles 8.
