Description

Den foreliggende opfindelse angår en rulleskodde af den i indledningen til krav 1 angivne art.The present invention relates to a roller shutter of the kind set forth in the preamble of claim 1.

En rulleskodde af derme art er beskrevet i beskrivelsen til DE-GM 1928212. Af de to bevægelige skinnedele, som danner føringsbanen for bevægelsen af stavene er den yderste skinnedel bevægelig udefter, altså mod ydersiden af bygningen, og bevirker en skråstilling af stavene, så at skodden kan tjene som soljalousi. Denne skinnedel er derfor tilgængelig udefra, f.eks. for en indbrudstyv, og derved bliver den ved rulleskodden tilstræbte tyverisikring mangelfuld.A roller shutter of this kind is described in the description of DE-GM 1928212. Of the two movable rail portions which form the guide path for the movement of the rods, the outer rail portion is movable outwards, i.e. towards the outside of the building, and causes an inclination of the rods, so that the shutters can serve as solar blinds. This rail part is therefore available from the outside, e.g. for a burglar, and thereby the anti-theft aim at the roller shutter becomes defective.

1 Den foreliggende opfindelse har til formål at anvise en rulleskodde af den førnævnte art, ved hvilken tyverisikringen er forbedret.The present invention has for its object to provide a roller shutter of the aforementioned kind by which the anti-theft protection is improved.

Rulleskodden ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 anførte.The roller shutter according to the invention is characterized by the part of claim 1.

Herved opnås en forbedret sikring mod indbrud, idet både den faste, som en glideskinne udformede skinne og den bevægelige, ligeledes som en glideskinne udformede skinne er anbragt beskyttet af en føringsskinne, og således ikke er tilgængelige for en indbrudstyv, uanset stillingen af stave ne.Hereby an improved protection against break-in is obtained, since both the fixed rail-shaped rail and the movable rail-like rail are arranged protected by a guide rail and are thus not accessible to a burglar regardless of the position of the rods.

Stavene føres sikkert og tæt gennem de i glideskinnerne anbragte føringslegemer. Det er derfor muligt at opnå en bedre lyd- og varmeisolering. Dette er især muligt ved at udføre den omhandlede rulleskodde efter de i den kendetegnende del af krav 2 anførte anvisninger, der også bidrager til sikringen mod indbrud.The rods are guided safely and tightly through the guide bodies arranged in the slides. It is therefore possible to achieve a better sound and heat insulation. This is especially possible by carrying out the roll roller in accordance with the instructions given in the characterizing part of claim 2, which also contribute to the protection against break-in.

Dette sidste gælder også den i krav 3 omhandlede udførelsesform for rulleskodden ifølge opfindelsen.The latter also applies to the embodiment of the roller shutter according to the invention according to claim 3.

I krav 4 er i den kendetegnende del anført en fordelagtig udførelsesform for den faste glideskinne, idet den kan udfomes i ét stykke med føringsskinnen.In claim 4, an advantageous embodiment of the fixed slide rail is indicated in that it can be unfolded in one piece with the guide rail.

Ved den i krav 5 omhandlede udførelsesform er den bevægelige glideskinne forsynet med mindst én tap, der indgriber i en føringsbane i føringsskinnen, hvorved enhver åbningsstilling er mulig.In the embodiment according to claim 5, the movable slide rail is provided with at least one pin which engages a guide track in the guide rail, whereby any opening position is possible.

Ifølge opfindelsen kan føringsbanen være udført halvcirkulær og føringsskinnen have en sådan bredde, at en stav er svingelig udover den vandrette stilling. Der opnås således god indstillelighed trods den opnåede indbrudssikkerhed.According to the invention, the guide web can be made semi-circular and the guide rail has a width such that a rod is pivotable beyond the horizontal position. Thus, good tunability is achieved despite the intrusion protection achieved.

I lukket stilling ligger stavene på grund af den gode føring tæt mod hinanden.In the closed position the rods are close to each other due to the good guide.

I de ovenfor ikke omtalte uselvstændige øvrige krav er angivet nogle særlig fordelagtige udførelsesformer for opfindelsen.Some of the other advantageous embodiments of the invention are set forth in the other independent claims mentioned above.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, hvor fig. 1 viser en udførelsesform for en rulleskodde ifølge opfindelsen skematisk og i snit set fra siden, fig. 2 samme, men med stavene i udsvinget stilling, fig. 3 et snit efter linien 3-3 i fig. 1 og fig. 4 samme med staven drejet 90°.The invention will now be explained in more detail with reference to the drawing, in which 1 shows an embodiment of a roller shutter according to the invention in schematic and sectional side view; 2, but with the rods in the oscillating position; 3 is a sectional view taken along line 3-3 of FIG. 1 and FIG. 4 same with the rod turned 90 °.

I figurerne betegner 1 en føringsskinne, i hvilken den egentlige rulleskodde af stave 2 er ført ved enderne under mellemkobling af glide-skinner 3 og 4, af hvilke skinnerne 3 er bevægelige, medens skinnerne 4 er fast anbragt, og som vist i fig. 4 kan være udformet i materialet i skinnen 1. Den bevægelige glideskinne 3 kan, se fig. 4, bevæges i retning af pilen F]_ og i de i fig. 3 viste stilling står stavene 2 lodret, medens skinnen 3 i fig. 4 står i en stilling, hvor stavene 2 er vandrette.In the figures, 1 denotes a guide rail in which the actual roller shutter of rods 2 is guided at the ends during interconnection of sliding rails 3 and 4, of which the rails 3 are movable, while the rails 4 are fixedly mounted, and as shown in FIG. 4 may be formed in the material of the rail 1. The movable sliding rail 3 can, see fig. 4 is moved in the direction of the arrow F1 and in those of FIG. 3, the rods 2 are vertical, while the rail 3 in FIG. 4 is in a position where the rods 2 are horizontal.

Hver stav 2 er fast, men drejeligt forbundet med den tilhørende glideskinne på den måde, at der på hver stav 2 er anbragt et drejeleje 5 og 6, af hvilke lejet 5 hører til den bevægelige skinne 3 og lejet 6 til den faste skinne 4, og drejelejerne 5 og 6 forbinder staven 2 med glide-skinnerne 3 og 4 under mellemkobling af føringslegemer 7 og 8, hvoraf i den viste udførelsesform, se fig. 2, føringslegemet 7 er udformet som en træk- og trykfast kæde, og føringslegemet 8 som en til hver stav 2 hørende føringsdel, som optager lejet 6 på grund af sin udformning og som med et profilfremspring griber ind i den faste skinne 3, hvilket fremspring er betegnet med 9. Den bevægelige skinne 3 har profilfremspring 10, der omslutter lejedelene på en sådan måde, at der opnås en tæt føring af staven 2.Each rod 2 is fixed but pivotally connected to the associated slide rail in that a rod bearing 5 and 6 is provided on each rod 2, of which the bearing 5 belongs to the movable rail 3 and the bearing 6 to the fixed rail 4, and the pivot bearings 5 and 6 connect the rod 2 to the slide rails 3 and 4 during interconnection of guide bodies 7 and 8, of which in the illustrated embodiment, see fig. 2, the guide body 7 is formed as a tensile and pressure-resistant chain, and the guide body 8 as a guide part belonging to each rod 2 which accepts the bearing 6 due to its configuration and which engages with the profile projection in the fixed rail 3, which projection is indicated by 9. The movable rail 3 has profile projections 10 which enclose the bearing parts in such a way that a tight guide of the rod 2 is obtained.

Lejerne 5 og 6 på hver stav 2 ligger forsat for denne midterlinie X-X, se fig. 2, på hver sin side af denne linie, idet staven udføres så tyk, at dette kan opnås, eller den forsynes med passende fremspring.The bearings 5 and 6 on each rod 2 are positioned for this center line X-X, see fig. 2, on either side of this line, the rod being made so thick as to be achieved or provided with appropriate protuberances.

Hver stav 2 er ved sin overkant 11 og underkant 12 forsynet med trin 14 og 15, så at de i lodret stilling overlapper hinanden og giver bedst mulig vindtæthed og lydtæthed.Each rod 2 is provided at its upper edge 11 and lower edge 12 with steps 14 and 15 so that they overlap in a vertical position and provide the best possible wind density and sound density.

I den egentlige føringsskinne 1 findes i den viste udførelsesform, se især fig. 1, en halvcirkulær føringsbane 16, hvori indgriber en tap 17, som er fast forbundet med den bevægelige glideskinne 3. En bevægelse af tappen 17 i banen 16 giver bevægelse af sinnen 3 i forhold til skinnen 4 i pilretningen Fj_ og f.eks. en bevægelse af stavene 2 fra den i fig. 2 viste halvt åbne stilling til den i fig. 1 viste helt lukkede stilling. På grund af udformningen af banen 16 og tappen 17 opnås en tvangsføring, der kan forsynes med ikke viste arreteringsmidler, så at enhver stilling af stavene 2 kan arreteres.In the actual guide rail 1 is found in the embodiment shown, see in particular fig. 1, a semicircular guide path 16, in which engages a pin 17, which is firmly connected to the movable slide rail 3. A movement of the pin 17 in the web 16 causes movement of the sensing 3 relative to the rail 4 in the arrow direction Fj_ and e.g. a movement of the rods 2 from the one shown in FIG. 2 shows the semi-open position shown in FIG. 1 completely closed position. Due to the design of the web 16 and the pin 17, a forced guide can be provided which can be provided with non-showing means so that any position of the bars 2 can be arrested.

Den i skinnen 1 indgribende ende af staven 2 er, se fig. 3 og 4, T-formet og består af en del 18, der strækker sig i længdeplanet af staven 2, og to flanger 19 og 20, der strækker sig mod for- og bagside af staven 2. Størrelsen af disse dele er valgt således, at der bliver plads til fremspringet 10 og i flangen 20 til lejet 6.The end of the rod 2 engaging the rail 1 is, see fig. 3 and 4, T-shaped and consists of a portion 18 extending in the longitudinal plane of the rod 2, and two flanges 19 and 20 extending towards the front and back of the rod 2. The size of these portions is selected as follows; that space is provided for the projection 10 and in the flange 20 for the bearing 6.

21, se især fig. 3, betegner en pakning, der i den lukkede stilling ligger an mod forsiden af stavene 2 og giver en ekstra tætning.21, see in particular FIG. 3, denotes a gasket which, in the closed position, abuts the front of the rods 2 and provides an additional seal.

Højden h]_ af skinnen 4 's føringslegeme 8 svarer omtrent til middelhøjden h.2 af en stav 2, se fig. 1 og 2. Da de enkelte legemer 8 ikke er forbundet med hinanden i den viste udførelsesform, er der kun en forbindelse til tryk mellem stavene 2 foran, medens føringslegemerne 7 giver en tryk- og trækfast forbindelse bagved mellem de enkelte stave 2.The height h1 of the guide body 8 of the rail 4 corresponds approximately to the average height h.2 of a rod 2, see fig. 1 and 2. Since the individual bodies 8 are not connected to each other in the illustrated embodiment, there is only a connection for pressure between the rods 2 in front, while the guide bodies 7 provide a pressure and tensile connection at the rear between the individual rods 2.

For tydeligheds skyld er tappen 17 på tegningen vist fremstående udefter, men profilet af føringsskinnen kan let vælges således, at tappen 17 er ført i et rum i skinnen og utilgængelig udefra, men let tilgængelig indefra.For the sake of clarity, the pin 17 of the drawing is shown to be prominent from the outside, but the profile of the guide rail can be easily selected such that the pin 17 is guided into a space in the rail and inaccessible from the outside, but easily accessible from the inside.

Rulleskoddens stave 2 kan fremstilles af ethvert passende materiale og kan anbringes på inder- eller ydersiden af vinduet, og stavene 2 kan fra en vertikal stilling over en horisontal stilling drejes til en nedad rettet vertikal stilling.The roller shutter rod 2 can be made of any suitable material and can be placed on the inside or outside of the window and the bars 2 can be rotated from a vertical position over a horizontal position to a downward vertical position.
