i 5 Den foreliggende opfindelse angår en afblændingsindretning til vinduer, særligt sådanne med konstant eller forbigående skråstilling af vinduesrammen, som i givet fald er vippelig omkring en vandret akse, og hvor afblændingsindretningen har en vandret overpro-10 fil, som er fastgjort til eller er en integreret del af vinduesrammens overstykke, en vandret og i forhold til overprofilen bevægelig underprofil, et afblændingselement, som kan foldes sammen opefter og er anbragt mellem overprofilen og underprofilen, snore, 15 der løber gennem i det mindste tre rækker af åbninger i afblændingselementet og kun tjener som føringselementer for underprofilen og afblændingselementet, og en indretning til afbøjning af snorene, idet denne indretning er fastgjort til eller er en integreret 20 del af vinduesrammens understykke.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window dimming device, particularly those having a constant or transient inclination of the window frame, which is tiltable about a horizontal axis, where appropriate, and wherein the dimming device has a horizontal upper profile which is attached to or is a an integral part of the window frame upper part, a horizontal and movable sub-profile relative to the upper profile, a dimming element which can be folded upwards and arranged between the upper profile and the sub-profile, cords running through at least three rows of openings in the dimming element and serving only as guiding elements for the sub-profile and the dimming element, and a device for deflecting the cords, said device being attached to or an integral part of the lower part of the window frame.

En sådan afblændingsindretning er kendt fra US patentskrift nr. 1.229.523, jfr. især fig. 11.Such a glare device is known from US Patent No. 1,229,523, cf. in particular FIG. 11th

25 Her består indretningen til afbøjning af snorene af afbøjningsruller, som er fastgjort til vinduesrammens understykke. Snorene forløber gennem åbningerne i afblændingselementet og underprofilen og er ført rundt omkring afbøjningsrullerne. Snorene forløber også 30 foran vinduesfladen, riår afblændingselementet er trukket helt op. I praksis giver dette vanskeligheder ved for eksempel vinduespudsning.25 Here, the device for deflecting the cords consists of deflection rollers which are attached to the lower part of the window frame. The cords extend through the apertures in the deflector element and the sub-profile and are passed around the deflection rollers. The cords also extend 30 in front of the window surface, when the dimming element is pulled up completely. In practice, this provides difficulties with, for example, window cleaning.

2 bedre de kendte afblændingsindretninger.2 better the known anti-glare devices.

Dette formål opnås med en afblændingsindretning af den indledningsvis angivne art, hvilken afblændings-5 indretning ifølge opfindelsen er særegen ved, at indretningen til at afbøje snorene er en ekstraprofil, at sideføringer, der er fastgjort til vinduesrammens sidestykker eller udgør en del vinduesrammen, tjener til føring af enderne af underprofilen og forbinder 10 overprofilen med ekstraprofilen, at hver snor går ud fra dens individuelle fæstepunkt i nærheden af den ene ende af overprofilen, gennem en række af åbninger i afblændingselementet og til underprofilen, idet hver går inden i denne til dens relevante sideføring 15 og ind i sidstnævnte nedefter, hver til dens relevante ende af ekstraprofilen og gennem denne til den modstående ende af ekstraprofilen, ind i den relevante sideføring og derfra via den relevante ende af un-dérprofilen gennem en yderligere række af åbninger i 20 afblændingselementet til et fæstepunkt i nærheden af enden af overprofilen, og at i det mindste én trækfjeder er anbragt ved hver snor.This object is achieved with a dimming device of the type mentioned initially, which dimming device according to the invention is peculiar in that the device for deflecting the cords is an extra profile, that side guides which are attached to the side frames of the window frame or form part of the window frame serve guiding the ends of the sub-profile and connecting the upper profile to the auxiliary profile, each string extending from its individual attachment point near one end of the upper profile, through a series of openings in the glare element and to the sub-profile, each passing within it to its relevant side guide 15 and into the latter downwards, each to its relevant end of the auxiliary profile and through it to the opposite end of the auxiliary profile, into the relevant side guide and thence via the relevant end of the lower profile through a further series of openings in the glare element for a fastening point near the end of the upper profile, and at least one feature spring is placed at each leash.

Det er herved opnået, at der ved en optrukket af-25 blændingsindretning ifølge opfindelsen ikke forløber nogen snore foran vinduet. Trækfjederen henholdsvis trækfjedrene optager størrelsesforskelle i snorene og forhindrer, at en snor slides ved overbelastning.It is hereby achieved that in a pulled-up glare device according to the invention no cords extend in front of the window. The draw spring and the draw spring, respectively, absorb size differences in the cords and prevent a cord from being worn by overloading.

30 Foreligger den opfindelsesmæssige afblændingsindret ning i en bredere udførelsesform, er det fordelagtigt, som omhandlet i krav 2, at de to snore er fastgjort til hvert fæstepunkt og er ført til underprofilen gennem to forskellige rækker af åbninger i af- 3If the inventive dimming device is provided in a wider embodiment, it is advantageous, as defined in claim 2, that the two cords are attached to each attachment point and are passed to the sub-profile through two different rows of apertures in the aperture.

4 I de viste udførelseseksempler er afblændingselementet 3 en plisseret polyesterdug. Indretningen ifølge opfindelsen er dog også anvendelig ved afblændingsindretninger med vandretliggende aluminium- eller 5 plastlameller; den er egnet til anvendelse i forbin delse med enhver form for afblændingselement, som kan foldes sammen eller skydes sammen.4 In the exemplary embodiments shown, the glare element 3 is a pleated polyester cloth. However, the device according to the invention is also applicable to glare devices with horizontal aluminum or plastic slats; it is suitable for use in connection with any type of glare element which can be folded or pushed together.

I den viste udformning er der anvendt to snore A og 10 B.In the embodiment shown, two cords A and 10 B.

Snoren A er fastgjort i overprofilen 1 ved Al. Den forlader overprofilen 1 ved A2 og går nedad gennem åbningerne i midten af afblændingselementet 3, hvor 15 den ved A3 går ind i underprofilen 2 og forløber gennem denne til A4. Ved A4 forlader den underprofilen 2, idet den forløber herfra nedad til A5, hvor den går ind i ekstraprofilen 5 og gennem denne til A6, og herfra opad til A7. Ved A7 går snoren A ind i under-20 profilen 2 til A8, hvor den forlader underprofilen 2; fra dette punkt forløber snoren atter opad gennem åbninger i afblændingselementet 3 til punkt A9. Fra A9 løber snoren gennem overprofilen 1 til punktet Al, hvor den fastgøres.The string A is attached to the upper profile 1 by A1. It leaves the upper profile 1 at A2 and goes downwards through the openings in the center of the glare element 3, where it at A3 enters the sub-profile 2 and extends through it to A4. At A4, it leaves the sub-profile 2, extending from here downwards to A5, where it enters the auxiliary profile 5 and through it to A6, and from here upwards to A7. At A7, the string A enters the sub-profile 2 to A8, where it leaves the sub-profile 2; from this point, the cord extends upward again through openings in the dimming element 3 to point A9. From A9, the cord runs through the upper profile 1 to the point A1 where it is attached.
