Description

Foreliggende oppfinnelse angår en kantforbindelse for ekstruderte profiler av metall eller plast, for dannelse av en veggkonstruksjon, idet de kanter på profilene som skal sammenføyes har langsgående ribber med innbyrdes avstand, slik at profilene kan sperres mot innbyrdes bevegelse på tvers av de nevnte The present invention relates to an edge connection for extruded profiles of metal or plastic, for the formation of a wall structure, the edges of the profiles to be joined having longitudinal ribs spaced apart, so that the profiles can be blocked against mutual movement across the aforementioned

kanter ved at ribbene parvis står i innbyrdes inngrep. edges in that the ribs in pairs are interlocked with each other.

Særlig ved bygging av vognkasser, containere og lignende blir sideveggene sammensatt av sammensettbare profiler. Profilene gir riktignok i de forskjelligste "Snap Lock"-utførelser en god forbindelse på tvers av profilretningen, men det oppnås ingen sikring mot forskyvning av profilene i lengderetningen. Dersom dette trengs, må profilene sveises, skrus eller nagles sammen. Av disse grunner lar selvbærende vareromkonstruksjon-er , containere og lignende seg bare fremstille på en omstende-lig måte, og ved bygging av varerom på tilhengere må det bygges solide understell. Especially when building wagon bodies, containers and the like, the side walls are composed of composite profiles. The profiles do indeed provide a good connection across the profile direction in the various "Snap Lock" designs, but no protection is achieved against displacement of the profiles in the longitudinal direction. If this is needed, the profiles must be welded, screwed or riveted together. For these reasons, self-supporting goods conversions, containers and the like can only be produced in a cumbersome way, and when building goods spaces on trailers, a solid undercarriage must be built.

Formålet med oppfinnelsen er å unngå disse ulemper, og i henhold til oppfinnelsen er dette oppnådd ved at det i et første par av ribber er dannet utsparinger som gjenstående partier av ribbene kan gripe inn i, mens det annet par av ribbene er profilert for å danne nevnte sperring mot innbyrdes tverrbevegelse, og for å muliggjøre en svingebevegelse mellom profilene for å føre det første par av ribber til innbyrdes inngrep. The purpose of the invention is to avoid these disadvantages, and according to the invention this is achieved by recesses being formed in a first pair of ribs into which remaining parts of the ribs can engage, while the second pair of ribs is profiled to form said blocking against mutual transverse movement, and to enable a pivoting movement between the profiles to bring the first pair of ribs into mutual engagement.

Ved hjelp av den foreliggende oppfinnelse kan alle vanlige "Snap Lock"-profilforbindelser derved sperres mot innbyrdes forskyvning i lengderetningen, og de sammenføyde deler er derved sperret mot innbyrdes bevegelse i alle retninger. Av disse deler lar det seg ved hjelp av øvre og undre bjelker bygge bærende vegger. By means of the present invention, all common "Snap Lock" profile connections can thereby be blocked against mutual displacement in the longitudinal direction, and the joined parts are thereby blocked against mutual movement in all directions. With the help of upper and lower beams, load-bearing walls can be built from these parts.

På de vedføyde tegninger er prinsippet ved oppfinnelsen vist ved hjelp av eksempler idet plateprofilene f.eks. kan danne en vegg eller et lasteplan. In the attached drawings, the principle of the invention is shown by means of examples, as the sheet profiles e.g. can form a wall or a loading plane.

Fig. 1 viser i perspektiv kantene av to profiler som skal sammenføyes. Fig. 2 viser et snitt etter linjen II-II i fig. 3, gjennom en dannet forbindelse, og fig. 3 viser et tverrsnitt gjennom for-bindelsen. I fig. 4, 5 og fig. 6 - 11 er vist andre utførel-sesformer av oppfinnelsen, vist på samme måte som i fig. 2 og 3. Fig. 1-3 viser to plateprofiler 1 og 2 fremstilt av f.eks. ekstrudert aluminium langs sine kanter utstyrt med et første par ribber 3, 4, i hvilke det ved fresing, stansing eller lignende er dannet utsparinger 5 og 6, og de gjenstående fremspring 7, 8 griper inn i utsparingene og danner en sperring som hindrer innbyrdes lengdeforskyvning av de to profilene. Fordi det er dannet et stort antall fremspring 7, 8 langs hvert profil, kan det opptas store krefter, slik at den sammensatte vegg styrkemessig forholder seg som en enkelt del, selv om det ikke finnes nagle- eller sveiseforbindelser eller lignende. Sammenføyningen kan utføres like enkelt som for plater uten utsparinger, ved at platene hektes sammen og svinges i forhold til hverandre. Fig. 1 shows in perspective the edges of two profiles to be joined. Fig. 2 shows a section along the line II-II in fig. 3, through a formed connection, and fig. 3 shows a cross-section through the connection. In fig. 4, 5 and fig. 6 - 11 show other embodiments of the invention, shown in the same way as in fig. 2 and 3. Fig. 1-3 show two plate profiles 1 and 2 produced by e.g. extruded aluminum along its edges equipped with a first pair of ribs 3, 4, in which recesses 5 and 6 are formed by milling, punching or the like, and the remaining projections 7, 8 engage in the recesses and form a barrier that prevents mutual longitudinal displacement of the two profiles. Because a large number of projections 7, 8 are formed along each profile, large forces can be absorbed, so that the composite wall behaves as a single part in terms of strength, even if there are no rivet or welding connections or the like. The joining can be carried out as easily as for boards without recesses, by hooking the boards together and pivoting in relation to each other.

Det er dessuten dannet et annet par ribber 9, 10, og ribben 9 har en langsgående vulst 17, mens ribben 10 har et langsgående spor 15 som har et tverrsnitt som er komplementært med vulsten 17. Ribben 9 befinner seg på et kantparti 16. Another pair of ribs 9, 10 is also formed, and the rib 9 has a longitudinal bead 17, while the rib 10 has a longitudinal groove 15 which has a cross-section which is complementary to the bead 17. The rib 9 is located on an edge portion 16.

Ribben 4 rager hovedsakelig som en forlengelse av plateprofilet 2, mens ribben 3 rager hovedsakelig i tverretning av plate-prof ilet 1, fra et kantparti 13. Kantpartiet 13 rager forbi ribben 3 og danner en dekklist 14. The rib 4 projects mainly as an extension of the plate profile 2, while the rib 3 projects mainly in the transverse direction of the plate profile 1, from an edge part 13. The edge part 13 projects past the rib 3 and forms a cover strip 14.

Som vist i fig. 2 og 3 kan vulsten 17 anbringes i sporet 15, og plateprofilene kan svinges i forhold til hverandre, idet vulsten 17 og sporet 15 sammen danner et hengselledd, slik at fremspringene 7 og 8 griper inn mellom hverandre og sperrer plateprofilene 1 og 2 mot å beveges innbyrdes i lengderetningen av fremspringene 7 og 8. Fig. 4 og 5 viser en utførelsesform der en vulst 27 og et spor 25 sammen danner et hengselledd, idet vulsten 27 befinner seg på et kantparti 26 på et plateprofil 21, mens sporet 25 befinner seg på et annet plateprofil 22. Plateprofilet 21 har dessuten et steg 29, mens plateprofilet 22 har et steg 30. Steget 29 griper med fremspring 23 inn mellom ribber 24 på steget 30, slik at det sperres mot innbyrdes bevegelse i lengderetningen av vulsten 27 og sporet 25. På profilet 22 er en kantforlengelse 32, som ender i en hake 33 som griper bak et fremspring 34 på profilet 21 når profilene er sammenføyd. Fig. 6 og 7 viser en utførelsesform der ribbene 43, 44 med utsparinger er utformet på'lignende måte som i fig. 4 og 5, mens hengseltorbindelsen er dannet av kantforlengelser 45, 46 på hvert av profilene 41, 42. Sneppforbindelsen dannes av sperreribber 52, 53 på forlengelser av profilveggene 50, 51. Fig. 8 og 9 viser en utførelsesform uten hengseltorbindelse. Det ene profil 61 har en dekklist 67 med renneform, og hver rennevegg har en innover ragende ribbe 63. På profilet 62 er det, på et kantparti 68, to fjærben 70 som rager inn i dekklisten 67, og som har utsparinger for å danne inngrep med ribbene 63, idet fjærbenene 70 har ribber 64 med hoder 71 som griper om ribbene 63. Fig. 10 og 11 viser en utførelsesform der to plateprofiler 81, 82 har hver sine par av veggforlengelser 85, 86, idet veggforlengelsene 85 på profilet 81 utgjør ribben 83 med utsparinger, mens det på profilet 81 er ribber 84 med utsparinger på innsiden av veggforlengelsene 86. Ribbene 83 griper inn mellom ribbene 84. As shown in fig. 2 and 3, the bead 17 can be placed in the groove 15, and the plate profiles can be pivoted in relation to each other, the bead 17 and the groove 15 together form a hinge joint, so that the protrusions 7 and 8 engage between each other and prevent the plate profiles 1 and 2 from moving mutually in the longitudinal direction of the projections 7 and 8. Fig. 4 and 5 show an embodiment in which a bead 27 and a groove 25 together form a hinge joint, the bead 27 being located on an edge portion 26 of a plate profile 21, while the groove 25 is located on another plate profile 22. The plate profile 21 also has a step 29, while the plate profile 22 has a step 30. The step 29 engages with projections 23 between ribs 24 on the step 30, so that it is blocked against mutual movement in the longitudinal direction of the bead 27 and the groove 25 On the profile 22 is an edge extension 32, which ends in a hook 33 which grips behind a projection 34 on the profile 21 when the profiles are joined. Fig. 6 and 7 show an embodiment where the ribs 43, 44 with recesses are designed in a similar manner as in fig. 4 and 5, while the hinge tor connection is formed by edge extensions 45, 46 on each of the profiles 41, 42. The snap connection is formed by locking ribs 52, 53 on extensions of the profile walls 50, 51. Fig. 8 and 9 show an embodiment without hinge tor connection. One profile 61 has a cover strip 67 with a gutter shape, and each gutter wall has an inwardly projecting rib 63. On the profile 62, on an edge part 68, there are two spring legs 70 that project into the cover strip 67, and which have recesses to form an engagement with the ribs 63, the spring legs 70 having ribs 64 with heads 71 which grip the ribs 63. Fig. 10 and 11 show an embodiment where two plate profiles 81, 82 each have their own pair of wall extensions 85, 86, the wall extensions 85 on the profile 81 forming the rib 83 with recesses, while on the profile 81 there are ribs 84 with recesses on the inside of the wall extensions 86. The ribs 83 engage between the ribs 84.

Fortanningen behøver ikke å være anordnet inne i profilfor-bindelsen slik at den ikke synes fra utsiden, idet fortanningen også kan være slik anordnet at den er synlig fra utsiden og kan kontrolleres. Som profiler er foruten metall-profiler også plastprofiler egnet, idet utformningen av tennene ikke bare kan være rettvinklede tannflanker men også med skrådde tannflanker. The serration does not need to be arranged inside the profile connection so that it is not visible from the outside, as the serration can also be arranged so that it is visible from the outside and can be checked. As profiles, in addition to metal profiles, plastic profiles are also suitable, as the design of the teeth can not only be right-angled tooth flanks but also with beveled tooth flanks.
