Den foreliggende opfindelse angår et beslag til et vendbart vindue af den type, hvor vinduesrammens øverste hjørner styres i styrespor i karmsiderne, og hvor vinduesrammen, der i begge sider er fastgjort til karmen ved hjælp af et beslag, er svingbar omkring en vandret akse, 5 hvilket beslag omfatter en vinduesarm, der ved sin ene endedel er svingbart lejret i vinduesrammen, og som ved sin anden endedel er hængslet til en øverste ledarm og en længere nederste ledarm, hvilke ledarme er drejeligt lejrede ved en karmbefæstigelse, der er beregnet til montering på vindueskarmen, og hvor karmbefæstigelsen samt den 10 nederste ledarm bærer samvirkende dele af en spærre mekanisme, som skal forhindre en ukontrolleret åbning af vinduet.The present invention relates to a bracket for a reversible window of the type in which the upper corners of the window frame are guided in guide grooves in the frame sides, and wherein the window frame, fixed on both sides by a bracket, is pivotable about a horizontal axis. which bracket comprises a window arm, which at one end is pivotally mounted in the window frame, and which at its other end part is hinged to an upper articulation arm and a longer lower articulation arm, which articulated arms are pivotally mounted by a frame attachment intended for mounting on the window frame, and where the frame mounting and the bottom 10 articulation arm carry interacting parts of a locking mechanism to prevent an uncontrolled opening of the window.

Et beslag af denne type er tidligere kendt gennem det svenske patentskrift nr. 7107194-8. Dette beslag har dog bl.a. den ulempe, at spærremekanismen på grund af sin udformning udsættes for trækkræf-15 ter, hvilket er mindre ønskværdigt af sikkerhedshensyn.A fitting of this type is previously known through Swedish Patent Specification No. 7107194-8. However, this bracket has among other things the disadvantage that, due to its design, the locking mechanism is subjected to tensile forces, which is less desirable for safety reasons.

Formålet med opfindelsen er at tilvejebringe et nyt og forbedret beslag, som har en enkel udformning, og som er enkelt og sikkert at anvende.The object of the invention is to provide a new and improved fitting which is simple in design and which is simple and safe to use.

Beslaget ifølge den foreliggende opfindelse er kendetegnet ved, at 20 den nederste ledarm er forlænget ud over sit omdrejningspunkt i karmbefæstigelsen med en fri endedel, der indgår i spærremekanismen, og som er udformet for at samvirke med en på karmbefæstigelsen svingbart lejret spærrehage, der indgår i spærremekanismen, og som er beregnet til i arbejdsstilling at danne et trykbelastet afstandselement mellem et på 25 beslaget tilvejebragt stop og endedelen. Herved opnås en spærremekanisme, som let kan anvendes til forskellige vinduesstørrelser, og som er let tilgængelig ved alle vinduesstørrelser, selv når vinduet er i omvendt stilling. Desuden opnås, at spærrekraften overføres direkte gennem tryk uden nævneværdig belastning af spærrehagens omdrejningstap.The bracket according to the present invention is characterized in that the lower link arm is extended beyond its pivot point in the frame attachment with a free end part which is included in the locking mechanism and which is designed to cooperate with a locking pivotable swivel part which is included in the frame. the locking mechanism, which is intended to form in a working position a pressure-loaded spacer between a stop provided on the bracket and the end portion. This provides a locking mechanism which can be easily used for different window sizes and is easily accessible at all window sizes, even when the window is in the reverse position. In addition, the locking force is obtained directly through pressure without appreciable load on the locking pin rotation.

30 Ifølge en fordelagtig udførelsesform er spærrehagen tilvejebragt således, at den ved tyngdekraftens påvirkning er svingbar til en låse-stilling mod stoppet. Herved opnås en god funktionssikkerhed.According to an advantageous embodiment, the latch is provided so that, under the influence of gravity, it is pivotable to a locking position against the stop. This ensures good functional safety.

Beslaget ifølge den foreliggende opfindelse skal herefter forklares nærmere under henvisning til den medfølgende tegning, hvor 35 fig. 1 viser et billede set forfra af et vindue, som er forsynet med et beslag ifølge den foreliggende opfindelse, fig. 2 et snit efter linien 11-I I i fig. 1 med vinduet i en bevægelsesstilling, fig. 3 et billede til belysning af en detalje af beslaget i fig. 2, 2The bracket according to the present invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 is a front view of a window provided with a bracket according to the present invention; FIG. 2 is a sectional view taken along line 11-I of FIG. 1 with the window in a moving position; FIG. 3 is a view illustrating a detail of the bracket of FIG. 2, 2

fig. 4 et beslag ifølge den foreliggende opfindelse, set fra vinduets inderside og i sammenfoldet tilstand, og fig. 5 et snit efter linien V-V i fig. 4.FIG. 4 shows a bracket according to the present invention, seen from the inside of the window and in the folded state, and fig. 5 is a section along the line V-V in FIG. 4th

Ifølge fig. 1 er der ved et vendbart vindue 1 tilvejebragt en 5 vinduesramme 2, der er vendbart ophængt i en vindueskarm 3 ved hjælp af to beslag 4, et pi hver side af vinduesrammen. Vinduesrammen 2 bliver herved svingbar omkring en i alt væsentligt vandret akse.According to FIG. 1, a reversible window 1 is provided with a 5 window frame 2, which is reversibly suspended in a window frame 3 by means of two fittings 4, one on each side of the window frame. The window frame 2 is thereby pivotable about a substantially horizontal axis.

Den mere detaljerede udformning af et beslag 4 er vist i fig. 2, hvor vinduet er delvist åbnet. Hvert af de øverste hjørner er forsynede 10 med en styreanordning (ikke vist) for at styre vinduesrammens overside langs et i vindueskarmen 3 tilvejebragt lodret styrespor 5. Ved at flytte vinduesrammens overside langs hele styresporet 5 kan vinduesrammen 2 vendes på konventionel måde. I hvert beslag 4 indgår en vinduesarm 6, som ved sin nederste endedel er svingbart forbundet med vinduesram-15 men 2, og som ved sin øverste endedel er hængslet til en øverste ledarm 7 og en længere nederste ledarm 8, hvilke ledarme er drejeligt lejrede ved en karmbefæstigelse 9, der er beregnet til montering på vindueskarmen 3. Karmbefæstigelsen 9 og den nederste ledarm 8 bærer samvirkende dele af en spærremekanisme 10, som skal forhindre, at 20 vinduet ukontrolleret åbnes ud over den stilling, som er vist i fig. 2.The more detailed configuration of a bracket 4 is shown in FIG. 2, where the window is partially opened. Each of the upper corners is provided with a guide (not shown) for controlling the upper side of the window frame along a vertical guide groove 5 provided in the window frame 3. By moving the upper side of the window frame along the entire guide track 5, the window frame 2 can be turned in a conventional manner. Each bracket 4 includes a window arm 6, which at its lower end portion is pivotally connected to the window frame 2, and which at its upper end portion is hinged to an upper link arm 7 and a longer lower link arm 8, which link arms are pivotally mounted at a frame mounting 9 intended for mounting on the window frame 3. The frame mounting 9 and the lower link arm 8 carry cooperating portions of a locking mechanism 10 which shall prevent the window from opening uncontrollably beyond the position shown in FIG. 2nd

Spærremekanismen 10 udgør tillige en såkaldt børnesikring for vinduet.The locking mechanism 10 also provides a so-called child lock for the window.

Som det fremgår af fig. 3 er den nederste ledarm 8 forlænget ud over sit omdrejningspunkt 11 i karmbefæstigelsen 9 med en fri endedel 12, der indgår i spærremekanismen 10, og som er udformet for at 25 samvirke med en spærrehage 14, der er svingbart lejret om en lejetap 13 på karmbefæstigelsen 9, og som indgår i spærremekanismen 10, og som er beregnet til i en arbejdsstilling at samvirke med et stop 15 på karmbefæstigelsen 9. Spærrehagen 14 er således udformet, at den under tyngdekraftens indvirkning vil prøve at indtage den i fig. 3 viste 30 arbejdsstilling, som udgør en låsestilling. Lejetappen 13 strækker sig gennem spærrehagen 14 mellem en knast 17, der samvirker med et fremspring 16 på endedelen 12, og en støttedel 18, som samvirker med stoppet 15. Når fremspringet 16 svinges i retning mod stoppet 15, vil spærrehagen 14 derved danne et trykbelastet afstandselement mellem 35 endedelen 12 og stoppet 15. Den indbyrdes placering af fremspringet 16 og stoppet 15 medfører, at lejetappen 13 stort set vil forblive ubelastet, når fremspringet 16 føres i retning mod stoppet 15.As shown in FIG. 3, the lower link arm 8 is extended beyond its pivot point 11 in the frame mounting 9 with a free end portion 12 included in the locking mechanism 10, which is designed to cooperate with a locking hook 14 pivotally mounted about a bearing pin 13 on the frame mounting 9, which is included in the locking mechanism 10, and which is intended to cooperate in a working position with a stop 15 on the frame fastening 9. The locking catch 14 is designed so that it will try to take the one shown in FIG. 3, which is a locking position. The bearing pin 13 extends through the catch 14 between a cam 17 which cooperates with a projection 16 on the end portion 12, and a support member 18 which cooperates with the stop 15. As the projection 16 is pivoted in the direction of the stop 15, the catch 14 will thereby form a thrust loaded. spacing element between the end portion 12 and the stop 15. The mutual placement of the projection 16 and the stop 15 causes the bearing pin 13 to remain largely unloaded as the projection 16 is directed in the direction of the stop 15.

For at kunne åbne vinduet ud over den i fig. 2 viste stilling, føres vinduesrammen 2 til en sådan stilling, at knasten 17 på spærreha-In order to open the window beyond the one shown in FIG. 2, the window frame 2 is moved to such a position that the cam 17 on the latch

3 gen 14 kan passere fremspringet 16 pi endedelen 12, når spærrehagen vrides i retning med piien 19 i fig. 3. Derefter er det muligt at dreje den nederste ledarm 8, f.eks. til den med streg-prik-linier i fig. 3 antydede stilling for således at åbne vinduet helt og eventuelt vende 5 vinduesrammen 2. Ved lukning af vinduet kommer fremspringet 16 på endedelen 12 til at glide langs med en kontaktflade 20 på spærrehagen 14, således at spærrehagen igen drejes i retning med pilen 19. Når den nederste ledarm 8 er drejet tilstrækkeligt langt, vil spærrehagen 14 falde tilbage til sin i fig. 3 viste stilling. Vinduet er nu igen sikret.3 gene 14 can pass the projection 16 in the end portion 12 when the latch is rotated in the direction of the arrow 19 in FIG. 3. Then it is possible to rotate the lower link arm 8, e.g. to the dash-dotted lines in FIG. 3 indicates position so as to open the window completely and optionally flip the window frame 2. Upon closing the window, the projection 16 on the end part 12 slides along a contact surface 20 on the latch 14, so that the latch again turns in the direction of the arrow 19. When when the lower link arm 8 is rotated long enough, the latch 14 will fall back to its position in FIG. 3. The window is now secured again.

10 Som det fremgår af fig. 4 og 5 er beslaget 4 udformet således, at en flangedel 21 på vinduesarmen gemmer og beskytter de forskellige dele i beslaget, når vinduet er i sin lukkede stilling. Herved beskyttes bl.a. spærremekanismen 10 fra utilbørlig beskadigelse udefra samtidig med, at der opnås en bekyttelse mod vejret. Endvidere er den øverste 15 ledarm 7 og den nederste ledarm 8 anbragt væsentligst på hver sin side af en kropdel 22 på vinduesarmen 6. Herved mindskes tendensen til en skæv belastning af vinduesarmen 6. Fiksering af karmbefæstigelsen 9 i vindueskarmen 3 lettes ved, at karmbefæstigelsen 9 ved begge hængselstederne for ledarmene 7 og 8 er tilvejebragt med udragende tappe 23, 20 som er beregnet til at gribe ind i tilsvarende fordybninger i vindueskarmen 3. På selve vinduesarmen 6 findes der en vindueskarmtap 24, som har et låsespor 25, og som er beregnet til at blive fikseret i vinduesrammen. Ved den nederste ende af karmbefæstigelsen 9 findes et beskyttelsesorgan 26 til spærrehagen 14. Herved bliver spærrehagen 25 svært tilgængelig udefra. Beskyttelsesorganet 26 kan f.eks. udgøres af en ombøjet del af karmbefæstigelsen 9.10 As can be seen from FIG. 4 and 5, the bracket 4 is designed such that a flange portion 21 of the window arm stores and protects the various parts of the bracket when the window is in its closed position. This protects, among other things, the locking mechanism 10 from undue external damage while providing protection against the weather. Furthermore, the upper 15 articulating arm 7 and the lower articulating arm 8 are arranged substantially on each side of a body part 22 of the window arm 6. This reduces the tendency for a skewed load of the window arm 6. Fixing of the frame attachment 9 in the window frame 3 is facilitated by the frame mounting 9 at both hinge locations of the link arms 7 and 8 are provided with protruding pins 23, 20 which are intended to engage corresponding recesses in the window frame 3. On the window arm 6 there is a window frame pin 24 which has a locking groove 25 and which is intended to be fixed in the window frame. At the lower end of the frame mounting 9 is a protective member 26 for the latch 14. Thus, the latch 25 becomes readily accessible from the outside. The protective means 26 may e.g. is constituted by a bent part of the frame attachment 9.

Spærremekanismen 10 tjener ikke bare til at at forhindre en utilsigtet åbning af vinduet, men den kan også spærre vinduet i omvendt stilling, således at det bliver muligt at pudse ydersiden. Alt efter 30 behovet kan spærremekanismen anbringes på den ene eller begge sider af vinduet.Not only does the locking mechanism 10 serve to prevent an unintended opening of the window, but it can also lock the window in the reverse position so that the exterior can be polished. Depending on the need, the locking mechanism can be placed on one or both sides of the window.

Geometrien for spærremekanismen 10 kan naturligvis ændres inden for visse grænser, uden den ovenfor beskrevne funktion sættes over styr.The geometry of the locking mechanism 10 can of course be changed within certain limits without overriding the function described above.
