Description

Den foreliggende frembringelse vedrører en vinduesramme omfattende en forreste og en bageste rammedel, der er indrettet til at blive indsat i en vægåbning fra hver sin side af væggen, især i en væg af sandwichkonstruktion med plane for- og bagpaneler, og hvor rammedelene omfatter et afsnit, der dækker et område af for- og bagpanel langs åb- . ningen, og en læbe, der er indrettet til at hvile mod en mellem den forreste og den bageste ramme ved hjælp af læberne fastklemt vinduesrude, samt hvor den forreste rammedel har fortandede flige, der er indrettet til låsende at samvirke med lommer i den bageste rammedel, hvilke lommer er forsynet med låseorganer for fligenes fortanding.The present invention relates to a window frame comprising a front and a rear frame member adapted to be inserted into a wall opening from either side of the wall, in particular in a sandwich structure with flat front and rear panels, the frame members comprising a section covering an area of front and rear panels along the open. the lip, and a lip adapted to rest against one between the front and rear frame by means of the lips jammed window pane, and wherein the front frame portion has toothed tabs adapted to lockably cooperate with pockets in the rear frame portion. , which pockets are provided with locking means for the teeth of the tabs.

I WO-publikation nr. 90/12187 er der beskrevet en vinduesramme, der er fremstillet ved sprøjtestøbning af plast. Vinduesrammmen omfatter en forreste og en bageste rammedel, der indsættes i vægåbningen fra hver sin side, idet den forreste rammedel har et antal fortandede flige, der passer ind i et tilsvarende antal lommer i den bageste rammedel. Ved indsætningen låses fortandingen i lommerne, og den forreste og bagste rammedel vil derefter udgøre en uadskillelig helhed, der danner forbindelsen mellem vinduesruden og væggen. Sprøjtestøbning af viduesrammerne frembyder store produktionsmæssige fordele med Tiensyn til tidsforbrug ved fremstillingen i forhold til samling af rammerne ud fra ekstruderede profiler, men medfører tillige betydelige omkostninger ved tilvejebringelsen af de ved sprøjtestøbningen anvendte forme. Ved den kendte vinduesramme skal der anvendes forskellige forme til fremstilling af den forreste og den bageste rammedel. Er der behov for at levere vinduesrammer i forskellige størrelser eller med på anden måde forskellig form eller udstyr bliver omkostningerne til forme meget store.WO Publication No. 90/12187 discloses a window frame made of plastic injection molding. The window frame comprises a front and a rear frame portion which is inserted into the wall opening from each side, the front frame portion having a plurality of toothed tabs that fit into a corresponding number of pockets in the rear frame portion. Upon insertion, the tooth is locked in the pockets, and the front and rear frame members will then form an inseparable whole, forming the connection between the window pane and the wall. Injection molding of the video frames offers great production advantages with Tiensyn for time spent in manufacturing compared to assembling the frames from extruded profiles, but also incurs significant costs in providing the molds used in the injection molding. In the known window frame, various molds are used to make the front and rear frame parts. If there is a need to supply window frames of different sizes or with different shapes or equipment, the cost of molds becomes very high.

Fra US A 3.769.769 kendes der en vinduesramme omfattende en forreste og en bageste rammedel, der er udstyret med et antal fremspring og tilsvarende recesser i de flader, hvormed de to rammedele ved monteringen støtter mod hinanden. De to rammedele er udformet som en tabt form, der ind-støbes i en støbt væg for derved at danne en vinduesramme med indfatning. Fremspringene og recesserne på de to dele er placeret symmetrisk i forhold til en symmertriakse, idet der symmetrisk i forhold til hver reces er placeret et fremspring. Ved monteringen kan to ens rammedele sammensættes blot ved, at den ene rammedel vendes 180° i forhold til den anden.From US A 3,769,769 there is known a window frame comprising a front and a rear frame part, which is provided with a number of projections and corresponding recesses in the surfaces with which the two frame parts during the mounting support each other. The two frame members are designed as a lost mold which is embedded in a molded wall to thereby form a window frame with frame. The projections and recesses on the two parts are symmetrically positioned relative to a symmetry axis, with a projection symmetrically relative to each recess. When mounting, two identical frame parts can be assembled simply by turning one frame part 180 ° relative to the other.

Det er et mål for frembringelsen at reducere omkostningerne ved fremstilling af viduesrammer, dels ved at reducere formomkostningerne ved at forreste og bageste rammme fremstilles ved hjælp af den samme form, dels ved at rammedelene har en sådan udformning, at det anvendte plastmateriale udnyttes effektivt til at give rammerne styrke og stivhed.It is an object of the invention to reduce the cost of producing frame frames, partly by reducing the cost of molding the front and rear frames made using the same mold, and partly by having the frame members in such a way that the plastic material used is effectively utilized to give the frame strength and stiffness.

Vinduesrammen ifølge frembringelsen er ejendommelig ved det i den kendetegnende del af krav 1 angivne. Ved at placere fligene og lommerne som angivet kan en forreste rammedel på kendt måde anvendes som bageste rammedel, blot den vendes 180° og indsættes i en tilsvarende, ikke vendt rammedel. Vinduesrammen kan derfor sammensættes af to identiske rammedele om ønsket, eller rammedelene kan fremstilles i to varianter, der kun afviger fra hinanden f.eks. i udseendet af de afsnit, som overlapper kanterne af væggen, idet de formdele, som formgiver disse afsnit er udskiftelige indlæg i sprøjtestøbeformene. Ved at placere lommerne og fligene på en på langs af rammedelenes sidestykker placeret ribbe fordeles kraftpåvirkningerne fra sammenlåsningen jævnt ud mod de tætnende flige og kanter, hvorved der med selv beskedne dimensioner kan opnås stor styrke og stivhed af rammedelene.The window frame according to the invention is peculiar to that of the characterizing part of claim 1. By positioning the tabs and pockets as indicated, a front frame member can be used in the known manner as a rear frame member, simply turning it 180 ° and inserting into a corresponding, non-facing frame member. The window frame can therefore be composed of two identical frame parts if desired, or the frame parts can be made in two variants which differ only from one another e.g. in the appearance of the sections that overlap the edges of the wall, the molding parts shaping these sections being interchangeable inserts in the injection molds. By placing the pockets and tabs on a rib longitudinally positioned by the side portions of the frame members, the force effects from the interlocking are evenly distributed to the sealing tabs and edges, whereby even strength of the frame members can be obtained with even modest dimensions.

Anvendelsen af Udskiftelige indlæg i sprøjtestøbeformene, som iøvrigt anvendes til fremstilling af såvel den forreste som den bageste rammedel, kan også udstrække sig til udformningen af de læber, som hviler mod selve rudelelementet. Der opnås derved ved frembringelsen mulighed for et forøget udvalg af varianter af vinduesrammen uden at omkostningerne ved tilvejebringelsen af formene stiger proportionalt med antallet af varianter.The use of Interchangeable inserts in the injection molds, which are otherwise used to produce both the front and rear frame members, can also extend to the design of the lips resting on the rudder element itself. In this way, an opportunity is made for an increased choice of variants of the window frame without the cost of providing the molds increasing proportionally to the number of variants.

Ved den foretrukne udformning i henhold til frembringelsen er den forreste rammedel identisk med den bageste. ·In the preferred embodiment according to the invention, the front frame member is identical to the rear. ·

Frembringelsen skal i det følgende beskrives nærmere under henvisning til tegningen på hvilken:The invention will now be described in more detail with reference to the drawing in which:

Fig. 1 viser en perspektivisk afbildning af en rammedel til en rektangulær vinduesramme ifølge frembringelsen, fig. 2a og fig. 2b viser henholdsvis et snit gennem et par rammedele placeret over for hinanden inden samling og rammedelene i snit efter samling omkring en sandwichvæg og med en et rudeelement indsat, og fig. 3a og fig. 3b viser snit svarende til snittene ifølge fig. 2a og fig. 2b, men i en udførelsesform beregnet til indsætning af et traditionelt termorudeelement.FIG. 1 is a perspective view of a frame member for a rectangular window frame according to the invention; FIG. 2a and fig. 2b respectively show a section through a pair of frame parts positioned opposite each other before assembly and the frame parts in section after assembly around a sandwich wall and with a window element inserted, and FIG. 3a and fig. 3b shows sections corresponding to the sections of FIG. 2a and fig. 2b, but in an embodiment intended for insertion of a conventional double glazing element.

Den på fig. 1 viste rammedel 1 er indrettet til at blive forbundet med en tilsvarende rammedel til dannelse af en vinduesramme, der fikserer et rudeelelement i forhold til en gennemgående åbning i en væg, fortrinsvis en væg af sandwichkonstruktion med plane for- og bagpaneler. Rammedelen er fremstillet i ét stykke af plast ved sprøjtestøbning, men består af fire sidestykker med i det væsentlige ens og konstant profil. Profilet omfatter et afsnit 2, der er indrettet til at strække sig et stykke ind over kanten af den væg, i hvilken vinduesrammen monteres. Rammedelem omfatter tillige en forstærkningsribbe 3, der tjener til forankring af de forbindelsesorganer, med hvilke de to rammedele indbyrdes forbindes, og til fordeling af de fra disse udgående spændinger. Til fiksering af rudeelementet mellem de to rammedele er hver rammedel forsynet med en læbe 4, der med sin ind mod rammedelens midte rettede kant 5 er indrettet til tæt-nende og fjedrende at hvile mod rudeelementet. Læben 4 danner derfor en vinkel på f.eks. ca. 60° med afsnittet 2. Forbindelsesorganerne består af tunger 6, der på en eller flere sideflader er forsynet med en fortanding 7, samt af lommer 8, der er udstyret med en styreåbning 9, hvis lysning i det væsentlige svarer til tværsnittet af tungen 6. I åbningen 9 er der placeret en form for pal, der ikke ses på fig. 1. Palen samvirker med fortandingen 7 og bevirker, at tungen 6 efter at være indsat i åbningen 9 ikke kan trækkes ud igen. Det ses på fig. 1, at fligene 6 og lommerne 8 er anbragt med tilnærmelsesvis ensartede mellemrum langs forstærknings- ribben 3 og sådan, at der vekselvis er placeret en flig 6 og en lomme 8. Arrangementet er endvidere symmetrisk omkring en af symmetriakserne 10 for rammedelen 1, dog således at der symmetrisk over for hver flig 6 er placeret en lomme 8. Ved dette arrangement kan man samle en vinduesramme ved hjælp af to identiske rammedele 1, blot den ene af disse vendes 180° i forhold til den anden.The FIG. 1 frame member 1 is arranged to be connected to a corresponding frame member to form a window frame which fixes a window element relative to a through opening in a wall, preferably a wall of sandwich construction with flat front and rear panels. The frame part is made of one piece of plastic by injection molding, but consists of four side pieces with substantially the same and constant profile. The profile comprises a section 2 arranged to extend a little over the edge of the wall in which the window frame is mounted. The frame member also comprises a reinforcing rib 3 which serves to anchor the connecting means with which the two frame members are interconnected and to distribute the voltages emanating from these. For fixing the pane member between the two frame members, each frame member is provided with a lip 4, which with its edge directed towards the middle of the frame member is arranged to rest tightly and resiliently against the pane member. The lip 4 therefore forms an angle of e.g. ca. 60 ° with section 2. The connecting members consist of tongues 6 provided on one or more side surfaces with a toothed 7, and of pockets 8 provided with a guide opening 9, the illumination of which corresponds substantially to the cross-section of the tongue 6. In the opening 9 is placed a form of pawl which is not seen in FIG. 1. The pawl interacts with the tooth 7 and prevents the tongue 6 from being inserted into the opening 9 again. Referring to FIG. 1, that the tabs 6 and the pockets 8 are arranged at approximately uniform intervals along the reinforcing rib 3, and so that a tab 6 and a pocket 8 are alternately arranged. The arrangement is furthermore symmetrical about one of the axis of symmetry 10 for the frame part 1, however, that a pocket 8. is arranged symmetrically opposite each tab 6. In this arrangement, a window frame can be assembled by means of two identical frame parts 1, just one of which is turned 180 ° relative to the other.

Fig. 2a viser et snit gennem to over for hinanden in^ den samlingen placerede rammedele 1 og 1'. Rammedelene 1 og 1' er identiske, men de er vendt således i forhold til hinanden, at en flig 6 netop bliver placeret ud for en lomme 8*. Det ses, at rammedelene omfatter et afsnit 2, der er indrettet til at dække kanten af den væg, i hvilken rammen indsættes, og en læbe 4 med en skarp kant 5, der kan ligge tætnende an nod rudelementet. Bag kanten af afsnittet 2 er der en ribbe 11, der er indrettet til at begrænse udpresningen af en streng af tætningsmasse, der kan placeres på indersiden af afsnittet 2 inden monteringen af rammedelene 1,1’. Læben 4 er ligeledes forsynet med en indvendig ribbe 12, der kan virke som ekstra tætning eller som styr for en streng af tætningsmasse ved monteringen. Fig. 2b viser rammedelene 1 ig 1' efter monteringen. Rudelementet 13 lægges på plads i den ene af rammedelene f.eks. 1', i hvilken det styres af lommerne 8', derefter pesses den anden rammedel 1 på plads fra den anden side af væggen 14. Det viste rudeele-ment er en termorude af den type, hvor de to lag glas eller acryl ligger an mod hinanden langs kanten.FIG. 2a shows a section through two opposite parts 1 and 1 'located in the assembly. The frame members 1 and 1 'are identical, but they are turned in relation to each other so that a tab 6 is placed just next to a pocket 8 *. It will be seen that the frame members comprise a section 2 arranged to cover the edge of the wall into which the frame is inserted, and a lip 4 with a sharp edge 5 which may be sealing to the rod element. Behind the edge of section 2 there is a rib 11 arranged to limit the pressing of a string of sealing compound which can be placed on the inside of section 2 prior to mounting of the frame members 1,1 '. The lip 4 is also provided with an inner rib 12 which can act as an extra seal or as a guide for a string of sealant during assembly. FIG. 2b shows the frame parts 1 in 1 'after mounting. The pane member 13 is placed in place in one of the frame members e.g. 1 ', in which it is guided by the pockets 8', then the second frame member 1 is pinned in place from the other side of the wall 14. The window element shown is a thermo-glass of the type in which the two layers of glass or acrylic abut. each other along the edge.

Fig. 3a og 3b viser tilsvarende afbildninger af rammedele, der er tilpasset til anvendelse i forbindelse med konventionelle termoruder med to lag plant glas. Rammedelene er magen til rammedelene ifølge fig. 2a bortset fra udformningen af læberne 4", der er smallere og forløber tilnærmelsesvis parallelt med afsnittene 2", der dækker kanten af væggen i vinduesåbningen.FIG. Figures 3a and 3b show corresponding views of frame parts adapted for use in conventional double-pane glass double glazing. The frame members are similar to the frame members of FIG. 2a except for the shape of the lips 4 "which are narrower and extend approximately parallel to the sections 2" covering the edge of the wall of the window opening.

Rammedelene 1 fremstilles ved sprøjtestøbning af en egnet plast f.eks. ABS, som har en god formstabilitet og vejrbestandighed. Det ses, at rammedelene ifølge fig. 2a og fig. 3a er ens bortset fra de læber, som hviler mod rudeele-The frame members 1 are made by injection molding a suitable plastic e.g. ABS, which has good form stability and weather resistance. It will be seen that the frame members of FIG. 2a and fig. 3a is the same except for the lips which rest against the window part-
