Opfindelsen vedrører et skærebeslag, navnlig til brug som udstiller for en sidehængslet vinduesramme, bestående af to med hinanden drejeligt forbundne arme, der er indbyrdes arreterbare i beslagets strak-5 te stilling ved hjælp af en i nærheden af armenes indbyrdes drejepunkt anordnet snapforbindelse omfattende en forsænkning eller udskæring i den ene arm til fjedrende indgreb med et fremspring på den anden.BACKGROUND OF THE INVENTION The invention relates to a cutting bracket, in particular for use as an exhibitor for a side hinged window frame, consisting of two interconnected arms that are mutually adjustable in the straightened position of the bracket by means of a snap connection arranged near the pivot point of the arms comprising a recess or cutout in one arm for resilient engagement with a projection on the other.
Der kendes skærebeslag af den ovenfor angivne 10 art, hvor armene er udformet af flad jern og er sammenhængslet ved hjælp af en hængseltap, der er nittet i hver ende. Når armene føres fra beslagets sammenfoldede stilling til den strakte stilling, passerer fremspringet på den anden arm ind over den første arm, hvorved armene 15 i området mellem fremspringet og drejningspunktet tvinges fra hinanden. Dette giver som følge armenes store bøjningsstivhed anledning til store friktionskræfter i hængselforbindelsen og i punktet, hvor fremspringet på den anden arm kontakter overfladen af den første 20 arm. Dette bevirker, at den videre åbning af beslaget, indtil dette er helt strakt, og arreteringsfremspringet på den anden arm griber ind i et hul i den første arm, kræver overvindelse af en betydelig friktion.Known brackets of the above type are known, in which the arms are formed of flat iron and are interconnected by means of a hinge pin riveted at each end. As the arms are moved from the folded position of the bracket to the stretched position, the projection of the second arm passes over the first arm, forcing the arms 15 in the region between the projection and the pivot point. As a result, the large bending stiffness of the arms gives rise to large frictional forces in the hinge joint and at the point where the projection of the second arm contacts the surface of the first 20 arm. This means that the further opening of the bracket until fully stretched and the arresting projection on the second arm engages in a hole in the first arm requires considerable friction to be overcome.
Det er en ulempe ved dette kendte beslag, at 25 man på grund af den store friktionskraft ikke har nogen sikker fornemmelse af, hvornår beslaget er helt åbent, og at vinduet derfor utilsigtet kan efterlades i en stilling, i hvilken det fastholdes af friktionskraften i det næsten strakte beslag, men hvor arreterings-30 fremspringet ikke er gået i indgreb med den tilhørende åbning. Vinduet kan da smække i, hvis det f.eks. af vinden påvirkes mod lukkestillingen med en kraft, der svarer til friktionskraften.It is a disadvantage of this known bracket that, due to the high frictional force, there is no certain sense of when the bracket is fully open, and that the window can therefore be left unintentionally in a position in which it is retained by the frictional force of the friction force. almost stretched brackets, but where the arresting projection has not engaged with the associated opening. The window can then be slammed in if, for example. of the wind is affected against the closing position with a force corresponding to the frictional force.
En anden ulempe er, at slid ved den nittede hæng-35 seltap efterhånden kan medføre en sådan reduktion af an- 2 DK 155132 lægstrykket mellem armene, at beslagets arreteringsvirk-nlng kan gå tabt.Another disadvantage is that wear and tear at the riveted hinge pin can eventually cause such a reduction in the compressive pressure between the arms that the arresting action of the bracket can be lost.
Skærebeslaget ifølge opfindelsen adskiller si& fra det kendte ved, at begge armene har U-formet tvær-5 snit, og at mindst den ene og fortrinsvis hver af flangerne i den ene arm har en forsænkning eller udskæring til indgreb med et arreteringsfremspring i den hosliggende flange af den anden arm.The cutting bracket according to the invention differs from the known in that both arms have a U-shaped cross-section and that at least one and preferably each of the flanges in one arm has a recess or cut-out for engagement with an arresting projection in the adjacent flange. of the other arm.
Herved opnås, at friktionskraften under åbningen 10 af vinduet kan være minimal, indtil beslaget nærmer sig den strakte stilling, hvorefter de to arme kan snappe over i denne stilling, i hvilken arreteringsfremspringet går i fuldt indgreb med arreteringsåbningen og dermed sikrer vinduet mod tilfældig lukning.Hereby, the frictional force under the opening 10 of the window can be minimized until the bracket approaches the stretched position, after which the two arms can snap into this position, in which the arresting projection fully engages with the arresting opening, thus securing the window against random closure.
15 Dette beror på placeringen af arreteringsfrem springet og arreteringsåbningen i armenes flanger og udnyttelsen af disses fjedervirkning, der desuden bevirker, at beslaget føres ud i sin strakte stilling, så snart fremspringet begynder at indgribe med og glide ned 20 i arreteringsåbningen.This is due to the location of the arresting spring and the arresting opening in the flanges of the arms and the utilization of their spring action, which further causes the bracket to move into its stretched position as soon as the projection begins to engage and slide down 20 into the arresting opening.
Denne virkning bliver særlig udpræget, når arm-tværsnittenes rygpartier i beslagets strakte stilling vender i indbyrdes modsatte retninger, og den anden arms arreteringsfremspring er udformet nær ved de frie side-25 kanter af denne arms flanger.This effect is particularly noticeable when the back portions of the arm cross sections in the stretched position of the bracket face in opposite directions, and the second arm arresting projection is formed near the free side edges of the flanges of this arm.
Opfindelsen forklares i det følgende nærmere ved hjælp af et udførelseseksempel og med henvisning til tegningen, på hvilken fig. 1 er et perspektivbillede af et beslag iføl-30 ge opfindelsen under åbning mod den strakte stilling, og fig. 2 et snit langs linien II-II i fig. 1 i beslagets fuldt strakte stilling.The invention will now be explained in more detail by way of example and with reference to the drawing, in which: FIG. 1 is a perspective view of a bracket according to the invention opening to the stretched position; and FIG. 2 is a section along line II-II of FIG. 1 in the fully extended position of the bracket.
Som vist i fig. 1 omfatter beslaget en første arm 1 og en anden arm 8, der begge er udformet med 35 U-profil. Armen 1 har ved sin første ende 3 et 3 3DK 1551320 hængslet element 7, hvormed armen kan fastgøres til en vindueskarm. Armen l er i den anden ende ved hjælp af to nitter 6 forbundet med armen 8, så armene kan drejes i forhold til hinanden om en drej-5 ningsakse 4, der stort set er vinkelret på armene 1, 8's flanger. Armene er hængslet således, at armtvær-snittenes rygpartier i beslagets strakte stilling vender i indbyrdes modsatte retninger. Ved armen l's anden ende er rygpartiet af O-profilet fjernet over en 10 vis strækning, således at profilets flanger virker som to separate bladfjedre, og armen har ved roden af hver bladfjeder en halvcirkelformet arreteringsåbning 5.As shown in FIG. 1, the bracket comprises a first arm 1 and a second arm 8, both of which have a 35 U profile. The arm 1 has at its first end 3 a 3 3DK 1551320 hinged element 7 with which the arm can be attached to a window frame. The arm 1 is connected at the other end by two rivets 6 to the arm 8 so that the arms can be rotated relative to one another about a axis of rotation 4 which is substantially perpendicular to the flanges of the arms 1, 8. The arms are hinged so that the back portions of the arm sections in the stretched position of the bracket face in opposite directions. At the other end of the arm 1, the back portion of the O-profile is removed over a certain stretch so that the flanges of the profile act as two separate leaf springs and the arm has a semi-circular arresting opening 5 at the root of each leaf spring.
Ved armen 8*s første ende 9 er i hver flange præget et hovedsagelig sfærisk arreteringsfremspring 15 12, hvis konvekse side vender mod den modstående flange, og fremspringene 12 ligger i en sådan afstand fra drejningsaksen 4, at de i beslagets strakte stilling indgriber med og passer i de respektive arreteringsåbninger 5 i armen 1. Ved armen 8's 20 anden ende er hængslet et element 13, ved hjælp af hvilket armen 8 kan fastgøres på en vindueramme.At the first end 9 of the arm 8 *, a substantially spherical arresting projection 15 12 is embossed in each flange, the convex side of which faces the opposite flange, and the projections 12 are at such a distance from the axis of rotation 4 that they engage with and in the stretched position of the bracket. fits into the respective arresting openings 5 of the arm 1. At the other end of the arm 8, a hinge 13 is provided by means of which the arm 8 can be secured to a window frame.
Beslaget monteres således i et vindue, at armen 8, når vinduet er lukket, er foldet helt hen over armen l og dækker denne, og at drejningsaksen 4 stort 25 set er parallel med rammens hængslingsakse og ligger i større afstand fra denne end elementerne 7 og 13.The bracket is mounted in a window so that the arm 8, when the window is closed, is folded completely over the arm 1 and covers it, and that the axis of rotation 4 is substantially parallel to the hinged axis of the frame and is at a greater distance from it than the elements 7 and 13th
Ved åbning af vinduet drejes armene 1 og 8 mod en stilling, hvor de stort set ligger i forlængelse af hinanden. Herved føres arreteringsfrem-30 springene 12 ind over de frie, som bladfjedre virkende dele af armen l’s flanger, og når fremspringene begynder at glide ned i arreteringsåbningerne, er fjedervirkningen af armenes flanger tilstrækkelig til, at beslaget snapper ud i den fuldt strakte 35 stilling og fastlåses.When opening the window, the arms 1 and 8 are rotated towards a position where they are largely in extension. Hereby, the arresting protrusions 12 are inserted over the free, leaf-acting portions of the flanges of the arm 1, and as the protrusions begin to slide down into the arresting openings, the spring action of the flanges of the arms is sufficient for the bracket to snap into the fully stretched position and locked.
