Den foreliggende opfindelse angår et til vippevinduer, navnlig skråt indbyggede tagvinduer, bestemt hængselbeslag af den art, der består af en første og en anden hængselpart med grundplader, der er bestemt til 5 montering på vinduets karm og dets ramme, og som har styreorganer i form af henholdsvis en på den første hængselpart siddende, cirkelbueformet føring og en i denne forskydelig glideskinne til fastlæggelse af en uden for vinduets tykkelse liggende vippeakse for ram-10 mens bevægelse i nærheden af lukkestillingen, og hvor den anden hængselpart i stillinger fjernere fra lukkestillingen er svingbar i forhold til den første hængselpart om en af glideskinnen båret drejetap, der ved rammens bevægelse bort fra lukkestillingen ved sving-15 ning om den nævnte vippeakse er bevægelig fra en stilling inden for vinduets tykkelse til en stilling uden for denne, samt hvor den anden hængselpart bærer en styretap med en sådan placering, at den under glide-skinnens forskydning i åbneretningen i den første hæng-20 selparts føring forskydes langs dennes konkave sidevæg og derved udelukker en svingning af den anden hængselpart om drejetappen, indtil styretappen efter glide-skinnens maksimale forskydning står ud for en åbning i den nævnte sidevæg.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to hinged windows, in particular obliquely built-in skylights, of a type consisting of a first and a second hinge part with base plates intended for mounting on the window frame and its frame, and having guide members in the form of a circular arcuate guide seated on the first hinge portion and a sliding rail, respectively, for defining an outside axis of the window thickness for frame movement in the vicinity of the closing position, and wherein the second hinge portion in positions further away from the closing position is pivotable relative to the first hinge part about a pivot carried by the sliding rail, which, when moving from the frame away from the closing position by pivoting about said tilt axis, is movable from a position within the thickness of the window to a position outside it, and where the second hinge part carries a guide pin in such a position that it slides under the slide rail opening in the direction of the first hinge part guide is displaced along its concave side wall, thereby excluding a swing of the second hinge part about the pivot until the guide post, after the maximum displacement of the sliding rail, faces an opening in said sidewall.

25 Et eksempel på sådanne hængselbeslag kendes fra dansk patentskrift 99 616, og forskellige modifikationer deraf har været på markedet gennem en årrække. For de kendte udførelser gælder, at styretappens tværmål svarer til den fri bredde i føringen, og i nogle til-30 fælde udnyttes tappen til ud over sin styrefunktion også at udøve en bremsefunktion under forskydningen i føringen, idet hensigten hermed er, at vinduesrammen kan fastholdes ved friktion i enhver stilling, indtil glideskinnen er forskudt maksimalt i åbneretningen. Med 35 henblik på bremsefunktionen er det kendt at indbygge en bladfjeder eller fjederlamel, der i ubelastet tilstand25 An example of such hinge fittings is known from Danish patent specification 99 616, and various modifications thereof have been on the market for a number of years. In the known embodiments, the cross-sectional dimensions of the guide pin correspond to the free width of the guide, and in some cases, the pin is used to exercise, in addition to its control function, a braking function during the displacement of the guide, the intention being that the window frame can be retained by friction in any position until the slide rail is displaced maximally in the opening direction. For the purpose of the braking function, it is known to incorporate a leaf spring or spring slat which in unloaded condition

Ved korrekt dimensionering og justering af fjede- j 5 ren kan der fra starten sikres en ønsket bremsefrik-tion, men denne vil kunne ændre sig som følge af slid og manglende vedligeholdelse, så at hængselbeslaget i hvert fald under ugunstige forhold ikke vil virke fuldt tilfredsstillende i det lange løb. Specielt kan der 10 opstå slid på føringens konvekse sidevæg og på den mod denne vendende side af styretappen.2 is slightly raised relative to the concave side of the guide, thereby forcing the steering pin for sliding systems not only towards the spring, but also towards the convex side of the guide. By properly sizing and adjusting the spring, a desired brake friction can be ensured from the start, but this can change as a result of wear and failure to maintain, so that the hinge bracket will not at least appear fully satisfactory under adverse conditions. in the long run. In particular, wear may occur on the convex sidewall of the guide and on the facing side of the guide pin.

Fra de kendte udførelser adskiller hængselbeslaget ifølge opfindelsen sig ved, at glideskinnen ved sin modsat drejetappen liggende ende har et breddeforminds-15 ket parti eller næb, mod hvilket styretappen har anlæg under giideskinnens forskydning.From the known embodiments, the hinge bracket according to the invention differs in that the sliding rail at its opposite end of the pivot has a width-shaped recessed portion or beak against which the guide pin has abutment during the displacement of the guide rail.

Ved denne foranstaltning sker der ingen ændring i tappens styrefunktion, men sliddet på tappen og på føringens konvekse sidevæg reduceres væsentligt, efter-20 som glideskinnen virker som en sko mellem tappen og den pågældende sidevæg, der følgelig ikke udsættes for et stærkt lokaliseret anlægstryk fra tappen.By this measure, there is no change in the steering function of the pin, but the wear on the pin and on the convex sidewall is substantially reduced, as the slider acts as a shoe between the pin and the relevant sidewall, which is consequently not subjected to a strongly localized pressure from the pin. .

En udførelsesform for hængselbeslaget ifølge opfindelsen er vist på tegningen, idet den til vinduets 25 ramme hørende hængselpart er vist punkteret efter maksimal forskydning af glideskinnen i åbneretningen og i stiplet streg efter videre omsvingning.An embodiment of the hinge bracket according to the invention is shown in the drawing, in which the hinge portion of the frame 25 of the window 25 is shown punctured after maximum displacement of the sliding rail in the opening direction and in dashed line after further turning.

Den til vinduets karm hørende første hængselpart 1 har en grundplade 2 med huller 3 for monterings-30 skruer og med opbukkede vægge 4 og 5, der danner den foran omtalte cirkelbueformede føring 6. I denne indgår en på tilsvarende måde bueformet glideskinne 7, der- er vist efter maksimal forskydning i åbneretningen.The first hinge portion 1 of the window frame 1 has a base plate 2 with holes 3 for mounting screws and with curved walls 4 and 5 forming the aforementioned circular arcuate guide 6. This includes a similarly arcuate sliding rail 7, which is shown after maximum displacement in the open direction.

En i glideskinnen siddende tap 8 har i denne stilling 35 anlæg mod kanten 9 af en ikke vist bro, der overdækker den nederste ende af føringen 6.A pin 8 seated in the slide rail has in this position 35 abut the edge 9 of a bridge (not shown) which covers the lower end of the guide 6.

Også den anden, til rammen hørende hængselpart 10 har en grundplade 11 med huller 12 for monteringsskruer, og denne grundplade er gennem en drejetap 13 forbundet med den del af glideskinnen 7, der lig-5 ger uden for føringen 6. Grundpladen 11 bærer en fastsiddende knast 14, der for overskuelighedens skyld er udeladt i rammeparten 10's punkteret viste mellemstilling, og hvis konvekse bagkant 15 under glideskinnens tilbagegående forskydning i føringen 6 10 glider langs en konkav del 16 af hængselparten l’s forkant. Denne forkantdel 16 fortsætter i en lige del 17, der efter påbegyndt omsvingning af rammeparten 10 fra den med punkteret streg viste mellemstilling danner anslag for den nedad vendende ende af knasten 14, som 15 derved hindrer en tilbagegående forskydning af glideskinnen 7, indtil rammeparten er bragt tilbage til me1lemst i11ingen.Also the other hinge portion 10 of the frame has a base plate 11 with holes 12 for mounting screws, and this base plate is connected through a pivot pin 13 to the part of the slide rail 7 which lies outside the guide 6. The base plate 11 carries a fixed cam 14, which, for the sake of clarity, is omitted in the center position shown by the punctured portion 10, and whose convex trailing edge 15 during the reciprocating slide of the sliding rail in the guide 6 10 slides along a concave portion 16 of the leading edge of the hinge portion 1. This leading portion 16 continues in a straight portion 17 which, after starting to turn the frame portion 10 from the centered dashed line position, impacts the downwardly facing end of the cam 14, which 15 thus prevents a reciprocal displacement of the slide rail 7 until the frame portion is brought. back to the member.

En på rammeparten 10's grundplade 11 fastsiddende styretap 18 hindrer enhver svingning af den-20 ne grundplade på drejetappen 13, indtil stoptappen 8 er kommet til anlæg mod brokanten 9. I denne situation befinder styretappen 18 sig ud for en sideåbning 19 i føringen 6's konkave sidevæg 5, så at den nu muliggør den videre omsvingning af rammen i åbneretnin-25 gen.A guide pin 18 fixed on the frame portion 10 of the base plate 11 prevents any oscillation of this base plate on the pivot pin 13 until the stop pin 8 comes into contact with the bridge edge 9. In this situation, the guide pin 18 is located at a side opening 19 in the concave sidewall of the guide 6 5, so that it now enables the further oscillation of the frame in the opening direction.

Så længe styretappen 18 befinder sig i føringen 6, ligger den fjedrende an dels mod den konkave væg 5, dels mod en næbformet ende 20 af glideskinnen 7, så at denne under et passende tryk holdes imod 30 føringens konvekse sidevæg 4. I den viste udførelsesform er der regnet med, at styretappen 18 i sig selv er tværfjedrende, idet den er sammensat af en bærer og en eller to ovale eller halvovale bladfjedre, men det fjedrende anlæg kan også være sikret ved, at der i fø-35 ringsvæggen 6 på kendt måde indgår en fjedrende lamel eller bladfjeder, der trykker styretappen imod næb-As long as the guide pin 18 is in the guide 6, the resilient abutment rests partly against the concave wall 5 and partly against a beak-shaped end 20 of the slide rail 7 so that it is held under a suitable pressure against the convex sidewall 4. In the illustrated embodiment For example, it is assumed that the guide pin 18 itself is transverse, being composed of a carrier and one or two oval or semi-oval leaf springs, but the resilient abutment may also be secured by the fact that in the guide wall 6 on way, includes a resilient lamella or leaf spring that pushes the guide pin against the beak
