Opfindelsen angår en hjørneforbindelse for hulprofiler af letmetal/ især til fremstilling af afstandsholderammer til termoruder, og bestående af en metallisk og i tværsnit omtrent U-formet hjørneforbindelsesvinkel, hvis grene er tilpas-5 set det indvendige tværsnit af hulprofilet, og hvis buede hjørneområde i forhold til grenenes sideflader er udformet ophøjet.BACKGROUND OF THE INVENTION The invention relates to a corner connection for light metal hollow profiles / especially for the manufacture of spacer frames for double glazing, and consisting of a metallic and cross-sectional approximately U-shaped corner connection angle, the branches of which are adapted to the inner cross-section of the hollow profile and whose curved corner area is proportionate. to the side surfaces of the branches are designed raised.

Hjørneforbindelsesvinkler, som opfindelsen går ud fra, er blevet kendt f.eks. fra tysk fremlæggelsesskrift nr. 2.532.896 og det tyske brugsmønster nr. 8.017,644.Corner connection angles on which the invention is based have been known e.g. from German Publication No. 2,532,896 and German usage pattern No. 8,017,644.

10 I begge tilfælde gås der ud fra en blikstrimmel, der er forsynet med indskæringer, udstansninger, indsnit og lignende, er i tværsnit U-formet præget langs sin længderetning og endelig bøjet i en vinkel. De derved dannede grene af hjørneforbindelsesvinkelen har en ydre kontur, der sva- 15 rer til den indre kontur af hulprofilet, i hvilket de enkelte grene skal indskubbes eller indpresses. Som følge heraf er hulprofilerne afskåret på tværs af deres længdeakse. Deres endekanter støder på kendt måde mod et ophøjet udformet hjørneområde på hjørneforbindelsesvinkelen.10 In both cases, a tin strip, which is provided with cut-outs, cut-outs, incisions and the like, is assumed to have a U-shaped cross-sectional shape along its longitudinal direction and finally bent at an angle. The branches formed by the corner connection angle have an outer contour which corresponds to the inner contour of the hollow profile, into which the individual branches are to be pushed or pressed. As a result, the hole profiles are cut across their longitudinal axis. Their end edges, in a known manner, abut an elevated shaped corner region of the corner connection angle.

20 I det første tilfælde bliver dette hjørneområde spændingsløst formet som en konsol, i hvilken der befinder sig en slids, der fra det indre hjørne af vinkelstykket forløber i retning mod dettes toppunkt. Med denne foranstaltning vil man opnå at kunne fremstille en fra 90° afvigende hjør- 25 neforbindelsesvinkel, som i den ønskede vinkelstilling af dens grene har en tilstrækkelig stivhed.In the first case, this corner region is tensionlessly shaped like a bracket in which is a slot extending from the inner corner of the angle piece towards its apex. By this measure, it will be possible to produce a corner joint angle deviating from 90 ° which has a sufficient stiffness in the desired angular position of its branches.

Ved genstanden ifølge brugsmønsteret bliver sidevæggene af grenene i hjørneområdet deformeret ved sammenfoldning, der ligeledes rager ophøjet frem fra grenenes sideflader.By the object according to the pattern of use, the side walls of the branches in the corner area are deformed by folding, which also protrudes protruding from the lateral surfaces of the branches.

30 De kendte hjørneforbindelsesvinkler har den ulempe, at de især i det buede hjørneområde skal være ustabile for at kunne ændres med hensyn til vinkelen.30 The known corner connection angles have the disadvantage that, especially in the curved corner region, they must be unstable in order to change with respect to the angle.

Formålet med den foreliggende opfindelse er at udforme hjørneforbindelsesvinkelen på en sådan måde, at den medThe object of the present invention is to design the corner connection angle in such a way that

2 simple formværktøjer let og nøjagtig lader sig fremstille og dermed i store styktal, idet den udøver en stiv og for den dannede ramme stabiliserende funktion.2 simple molding tools can be easily and accurately manufactured and thus in large numbers, performing a rigid and stabilizing function for the formed frame.

Idet der gås ud fra fremlæggelsesskriftet opnås dette ved, 5 at sidevæggene på de U-formede grene i hjørneområdet er anbragt hinanden overlappende, idet et vægområde, der grænser til et på tværs af grenens længdeakse forløbende indsnit, er forsat ud fra den oprindelige plan med et til dets vægtykkelse svarende stykke og efter vinkelbøjningen 10 kommer til at ligge an mod det andet udeformerede, mod indsnittet grænsende vægområde.Assuming the presentation letter, this is achieved by 5 overlapping the side walls of the U-shaped branches in the corner area, a wall area adjacent to a longitudinal axis extending transversely of the branch is set from the original plane with one piece corresponding to its wall thickness and after the angular bend 10 will abut the second undeformed wall area adjacent to the incision.

En på denne måde udformet hjørneforbindelsesvinkel lader sig på særlig simpel måde automatisk fremstille og deformere ud fra et bånd. Der gives nemlig den mulighed at 15 foretage indsnittet ifølge opfindelsen med de tilgrænsende, forsatte afsnit i samme arbejdsgang som forberedelsen til senere U-formet profilering af hjørneforbindelsesvinkelen.An angular joint angle formed in this way can be manufactured and deformed automatically from a strip in a particularly simple manner. Namely, it is given the opportunity to make the incision according to the invention with the adjacent, continued sections in the same operation as the preparation for later U-shaped profiling of the corner joint angle.

Bøjer man derefter det ϋ-formede profil til dannelse af de for det meste 90° på hinanden stående grene, da griber de 20 til indsnittet grænsende vægområder ind over hinanden og danner en geometrisk bestemt overlapning, som ophøjet rager ud over grenenes sideflader med et stykke svarende til vægtykkelsen. Kanterne af denne overlapning danner ligeledes anslagskanter for hulprofilerne, der skydes på 25 grenene.If the ϋ-shaped profile is then bent to form the mostly 90 ° spaced branches, the 20 adjacent wall areas intersect and form a geometrically determined overlap which extends protruding over the side surfaces of the branches by one piece corresponding to the wall thickness. The edges of this overlap also form abutment edges for the hollow profiles that are fired on the 25 branches.

Det har vist sig fordelagtigt at udforme bunden af indsnittet halvcirkelformet. Derved undgås uønskede revnedannelser ved udprægning af det ved indsnittet liggende vægafsnit.It has proved advantageous to shape the bottom of the semicircular incision. This avoids undesirable cracking by protruding the wall section at the incision.

Af samme årsag anbefales det at dimensionere dybden af 30 indsnittet mindre end dybden af det hosliggende og ud fra den oprindelige plan forsatte vægområde.For the same reason, it is recommended to dimension the depth of the 30 incision less than the depth of the adjacent and from the original planar wall area.

I en udførelsesform for opfindelsen har hjørneforbindelsesvinkelen i den ydre side af det buede hjørneområde en i tværsnit omtrent V-formet, langs længdeaksen forløbendeIn one embodiment of the invention, the corner junction angle in the outer side of the curved corner region has a cross-section approximately V-shaped, extending along the longitudinal axis.

3 og i grenenes ydre flade udløbende, sikkeagtig indtryk-ning. Lignende stabiliseringsforanstaltninger er ganske vist kendt. Ved opfindelsen foretrækkes en fra ydersiden indadrettet indtrykning, ved hvilken 2/5 af de tilgræn-5 sende vinkelgrene hver deformeres.3, and the exterior surface of the branches, which appears to be spiky. Similar stabilization measures are admittedly known. In the invention, an inward-facing indentation is preferred in which 2/5 of the adjacent angular branches are each deformed.

En således fremstillet hjørneforbindelsesvinkel er formstiv og dermed særlig egnet til stabilisering af en letmetalramme. Uanset dette kan de mod hinanden grænsende kanter af de overlappende vægafsnit også på sædvanlig 10 måde være sammenloddet.A corner joint angle thus produced is rigid and thus particularly suitable for stabilizing a light metal frame. Notwithstanding this, the adjacent edges of the overlapping wall sections may also be welded together in the usual manner.

Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, der skematisk og som eksempel viser enkeltheder ved opfindelsen, og hvor fig. 1 viser en hjørneforbindelsesvinkel set fra siden, 15 fig. 2 hjørneforbindelsesvinkelen i fig. 1 set fra oven, fig. 3 et tværsnit gennem hjørneområdet af hjørneforbindelsesvinkelen i fig. 1, fig. 4 en U-formet del for hjørneforbindelsesvinkelen i et mellemstadie før bøjning af denne del, set fra 20 neden, fig. 5 en udstanset del for hjørneforbindelsesvinkler set fra oven og fig. 6 indsnittene set fra oven i større målestok.The invention is explained in more detail below with reference to the drawing, which schematically and by way of example illustrates details of the invention, and in which fig. 1 is a side view of a corner connection angle; FIG. 2 shows the corner connection angle of FIG. 1, FIG. 3 is a cross section through the corner region of the corner connection angle of FIG. 1, FIG. 4 shows a U-shaped part for the corner connection angle at an intermediate stage before bending this part, as seen from below, fig. 5 is a plan view of a cut-out section for corner connection angles; and FIG. The 6 sections are viewed from above on a larger scale.

I fig. 1 er vist en hjørneforbindelsesvinkel 1 med to ved 25 afbøjning frembragte grene 2 og 3, mellem hvilke der findes et buet hjørneområde 4.In FIG. 1, a corner connection angle 1 is shown with two bends 2 and 3 provided by deflection, between which there is a curved corner region 4.

På grenene 2 og 3 indskydes endeområderne af hulprofiler 5 og 6 af letmetal, således at der på denne måde kan dannes en lukket ramme. Til fiksering af hulprofilerne 5 og 6 30 på grenene 2 og 3 findes udad afbøjede fremspring 9, der med friktion støtter mod den indvendige flade af hulprofilerne 5 og 6.On the branches 2 and 3, the end regions of the hollow sections 5 and 6 are made of light metal so that a closed frame can be formed in this way. For fixing the hollow profiles 5 and 6 30 on the branches 2 and 3 there are outwardly deflected projections 9 which with friction support the inner surface of the hollow profiles 5 and 6.

Hjørneområdet 4 er til siderne dannet af overlapninger 8 af vægområderne 13 og 14, se fig. 3 og 4. Disse overlapninger 8 har anslagskanter 7, mod hvilke endekanterne af hulprofilerne 5 og 6 kommer i anlæg.The corner region 4 is formed on the sides by overlaps 8 of the wall regions 13 and 14, see fig. 3 and 4. These overlaps 8 have abutment edges 7 against which the end edges of the hollow profiles 5 and 6 abut.

5 Stivheden af hjørneforbindelsesvinkelen 1 bestemmes i det væsentlige af en sikkeformet indtrykning 10, der langs den langsgående midterplan ude fra er således indtrykket i krumningsområde 4 af hjørneforbindelsesvinkelen 1, at denne indtrykning 10 omfatter 2/5 af grenene 2 og 3. Ved 10 denne spændingsløse deformering bliver desuden det faste anlæg af de overlapningen 8 dannende vægområder 13 og 14 forbedret.5 The stiffness of the corner joint angle 1 is determined essentially by a zig-shaped impression 10 which, along the longitudinal median plane from the outside, is so impressed in the curvature region 4 of the corner joint angle 1 that this impression 10 comprises 2/5 of the branches 2 and 3. At 10 this stressless Furthermore, the deformation of the overlap 8 forming wall regions 13 and 14 is improved.

I fig. 3 til 6 er vist, hvorledes overlapningen 8 dannes.In FIG. 3 to 6 are shown how the overlap 8 is formed.

Den udstansede del 15 for hjørneforbindelsesvinkelen 1 15 i fig. 5 bliver først ved kanten forsynet med på tværs af længderetningen forløbende indsnit 12. Et til disse indsnit 12 grænsende vægområde 13 bliver forsat med et stykke svarende til dets vægtykkelse, hvorimod det andet tilgrænsende vægområde 14 forbliver udeformeret. Disse 20 vægområder 13 og 14 er bestanddele af de U-formet afbøjede sidevægge af grenene 2 og 3. Hvis man nu bøjer det i fig.The punched portion 15 of the corner connection angle 1 15 of FIG. 5 is first provided at the edge with transverse longitudinal incisions 12. One wall area 13 adjacent to these incisions 12 is provided with a piece corresponding to its wall thickness, while the other adjacent wall area 14 remains unformed. These 20 wall regions 13 and 14 are components of the U-shaped deflected sidewalls of branches 2 and 3. If you now bend it in FIG.

4 viste, U-formede profil således, at der opstår den i fig. 1 viste form, griber det forsatte vægområde 13 om det udeformerede vægområde 14. Begge ligger i den ombøjede 25 stilling mod hinanden og danner dermed overlapningen 8.4 shows the U-shaped profile so as to produce the U-shaped profile shown in FIG. 1, the offset wall region 13 engages the undeformed wall region 14. Both lie in the bent 25 position against each other, thus forming the overlap 8.

Området for overlapningen 8 kan desuden ekstra stabiliseres ved en tosidig punktsvejsning. Hjørnevinkelen ifølge opfindelsen er således udformet, at der kan ske en fremstilling af forskellige materialer, der også kan loddes.The area of the overlap 8 can also be extra stabilized by a two-sided spot welding. The corner angle according to the invention is designed so that a variety of materials which can also be soldered can be made.

30 Som fig. 5 viser i et udsnit, bliver hjørneforbindelsesvinklerne skridtvis udstanset af et blikbånd 17, til hvis fremføring der findes medbringerhuller 16. De enkelte udstansedeAs FIG. 5 shows in a section, the corner connection angles are incrementally punched by an eye tape 17 to whose projection there are carrier holes 16. The individual punched

5 dele 15 bliver dannet for enderne først med udstansninger 18 og til siderne af skilleslidser 19. Med de parallelt med skilleslidserne 19 parallelle, stiplede linier 20 er vist bøjningskanter, omkring hvilke den U-formede 5 afbøjning af grenene 2 og 3 sker i en ikke vist yderligere arbejdsgang.5 portions 15 are formed at the ends first with punches 18 and to the sides of dividing slots 19. With the dashed lines 20 parallel to the dividing slots 19, bending edges are shown around which the U-shaped deflection of branches 2 and 3 occurs in a shown additional workflow.

Fra skilleslidserne 19 udgår indsnittene 12, hvis bund 21 er halvcirkelformet for ved senere ombøjninger at undgå en revnedannelse. Dybden af indsnittene 12 er mindre 10 end dybden af de tilgrænsende udprægninger 13, hvis fladeområde i fig. 6 er begrænset med punkterede linier 22. Efter afslutning af formgivningen bliver de enkelte udstansede dele 15 adskilt fra resten af blikbåndet 17 ved udstansning langs den stiplede linie 23.From the slits 19, the incisions 12, the bottom 21 of which is semi-circular in shape, are removed in order to avoid cracking at later bends. The depth of the incisions 12 is less than the depth of the adjacent recesses 13, the area of which of FIG. 6 is restricted by dashed lines 22. After completion of the molding, the individual punched portions 15 are separated from the rest of the tin strip 17 by punching along the dotted line 23.
