Description

Opfindelsen angår et bærebeslag til rullegardin-stokke, hvilket beslag på kendt måde består af en støbt brik af i nogen grad elastisk plastmateriale og med en åbning til drejefast optagelse af en firkanttap på 5 rullegardinstokken samt en fra brikkens kant til denne åbning førende indføringsslids for tappen.BACKGROUND OF THE INVENTION The invention relates to a roller bracket support bracket, which bracket in known manner consists of a molded piece of somewhat elastic plastic material and with an opening for pivotally accommodating a square tab on the roller blind and a leading insert slot for the tab from this bracket. .
Der er i Tyskland udviklet et sådant bærebeslag, som er specielt beregnet til brug ved ovenlysvinduer, og er indrettet til fastskruning på vindues-10 rammens sidestykker ved de øverste, indvendige hjørner, så at beslagene samtidig slutter til rammens overstykke. Alt efter omstændighederne kan beslaget dog også monteres på anden måde, eksempelvis på tilsætningsstykker hørende til vinduet.In Germany, such a support bracket, specially designed for use with skylights, has been developed and is fixed for fastening on the side windows of the window frame at the upper, inner corners so that the brackets at the same time connect to the top of the frame. Depending on the circumstances, however, the bracket can also be mounted in another way, for example on fittings belonging to the window.
15 I dette kendte beslag har tapåbningen og ind føringsslidsen til denne i princippet samme udformning som i traditionelle rullegardinbeslag af udstanset metalplade, idet de tilsammen danner et vinkelformet spor og ved overgangen mellem slidsens inderende og 20 åbningen har en knast eller et fremspring, der skal hindre firkanttappen i at hoppe ud af åbningen.15 In this known bracket, the tap opening and its insertion slot have in principle the same design as in traditional die-cut metal sheet roller fittings, together forming an angular groove and at the transition between the end of the slot and the opening having a cam or protrusion which is to prevent the square pin in jumping out of the opening.
Gennem opfindelsen tilsigtes det at skabe større sikkerhed på dette punkt uden en samtidig komplice-ring af beslagets udformning eller fordyrelse af dets 25 fremstilling.It is an object of the invention to provide greater security at this point without simultaneously complicating the design or costing of its bracket.
Med henblik herpå er bærebeslaget ifølge opfindelsen ejendommeligt ved, at brikken i tilslutning til indføringsslidsen har en fjedrende tunge, som i sin normalstilling danner en spærre for åb-30 ningen i retning mod indføringsslidsen, og som under indføring af tappen i retning mod åbningen er elastisk bøjelig til en stilling, i hvilken spærrevirkningen er ophævet.To this end, the carrier according to the invention is peculiar in that the piece adjacent to the insertion slot has a resilient tongue which in its normal position forms a lock for the opening towards the insertion slot and which during the insertion of the pin towards the opening is elastic. bendable to a position in which the blocking effect is lifted.
Ved denne udførelse giver den fjedrende tunge 35 fuld sikkerhed for, at firkanttappen ikke util- 146084 2 sigtet kan komme fri af åbningen, idet dette forudsætter en tilbagebøjning af tungen fra spærrestillingen, hvilket ikke kan ske ved en eller anden tilfældig påvirkning. Den forøgede sikkerhed kan 5 være af særlig vigtighed, når beslaget monteres på et vippevindues ramme i stedet for på den faststående karm, idet tungen da selv under vipperammens omsvingning til pudsestillingen hindrer firkanttappen i at glide ud af åbningen og videre ud gen-10 nem slidsen.In this embodiment, the resilient tongue 35 provides full assurance that the square pin will not unintentionally be released from the opening, as this requires a bending of the tongue from the locking position, which cannot be effected by some random action. The increased safety may be of particular importance when the bracket is mounted on the frame of a rocker window rather than on the fixed frame, since even during the swing of the rocker frame to the plaster position, the tongue prevents sliding out of the opening and further out through the slot. .
Når bærebeslaget er af den foran omtalte art, hvor indføringsslidsen og åbningen tilsammen danner et vinkelformet spor, kan den fjedrende tunge hensigtsmæssigt danne bund alene i den til indførings-15 slidsen svarende del af dette spor og i normalstillingen med sin fri ende liggerspærrende ud for åbningen. I dette tilfælde vil tungen normalt end ikke berøres af den i åbningen hvilende firkanttap og vil derfor være helt upåvirket i spærrestillingen.When the support bracket is of the aforementioned kind, in which the insertion slot and the opening together form an angular groove, the resilient tongue can conveniently form a base only in the portion corresponding to the insertion slot and in the normal position with its free end restraining the opening. . In this case, the tongue will normally not even be touched by the square tab resting in the opening and will therefore be completely unaffected in the locking position.
20 1 denne udførelsesform er bærebeslaget ifølge opfindelsen nærmere forklaret i det følgende under henvisning til tegningen, på hvilken fig. 1 viser dette bærebeslag, set fra forsiden , og 25 fig. 2 et snit efter linien II-II i fig. 1.In this embodiment, the carrier according to the invention is explained in more detail below with reference to the drawing, in which fig. 1 shows this front bracket, and FIG. 2 is a sectional view taken along line II-II of FIG. First
I den viste udførelsesform har beslaget trapez-facon med parallelle for- og bagkanter 1 og 2 og en derpå vinkelret underkant 3 samt en skrå overkant 4. Desuden har bagsiden 5, fig. 2, et vist smig i 30 forhold til forsiden 6.In the illustrated embodiment, the bracket has a trapezoidal shape with parallel front and rear edges 1 and 2 and a perpendicular lower edge 3 thereon and an inclined upper edge 4. In addition, the rear side 5, fig. 2, a certain flattery in relation to the front 6.
Beslaget er fremstillet ved støbning i ét stykke og består af et i nogen grad elastisk materiale, såsom nylon. Forsiden 6 er sammenhængende med et par knaster 7 med forsænkede huller 8 for monte-35 ringsskruer, og mellem disse knaster har forsiden 6 146084 3 en ret bred slids 9, der udgår fra forkanten 1 og ved sin inderende går over i en siderettet åbning 10 for en firkanttap 11 på et rullegardin. Denne tap er i begge figurerne antydet i punkteret streg.The bracket is made of one-piece molding and consists of some elastic material such as nylon. The front 6 is contiguous with a pair of lugs 7 with recessed holes 8 for mounting screws, and between these lugs the front 6 has a rather wide slot 9 extending from the leading edge 1 and at its inner end into a lateral opening 10 for a square tab 11 on a roller blind. This loss is indicated in dashed lines in both figures.
5 Ved forkanten 1 har beslaget en bro 12, der danner bund i den yderste del af slidsen 9, og som ved sin på tegningen opadvendende kant er sammenhængende med roden af en tunge 13, der i sin ubelastede tilstand skråner fremad mod forsiden 6 10 og danner bund i den resterende del af indføringsslidsen 9.5 At the leading edge 1, the bracket has a bridge 12 which forms a bottom in the outer part of the slot 9 and which at its upwardly facing edge is connected to the root of a tongue 13, which in its unstressed state slopes forwardly towards the front 6 10 and forms the bottom of the remaining portion of the insertion slot 9.
Når firkanttappen 11 føres ind i denne slids, dvs. opad på tegningen, lægger dens endeflade sig an mod tungen 13 og bøjer den tilbage, så at tappen 15 kan passere helt ind i slidsen og derpå kan sideforskydes ind i åbningen 10, så at den atter slipper tungen 13. Denne fjedrer da tilbage til den i fig. 2 viste stilling, i hvilken dens fri ende danner en effektiv spærre for tappen 11 i åbningen 20 10.When the square pin 11 is inserted into this slot, i. upwardly on the drawing, its end surface abuts the tongue 13 and bends it back so that the pin 15 can pass all the way into the slot and then sideways into the opening 10 so that it again releases the tongue 13. This then springs back into it. in FIG. 2, in which its free end forms an effective lock for the pin 11 in the opening 20 10.
