145703 i145703 i

Den foreliggende opfindelse angår et indstilleligt udskyderbeslag, hvormed man kan lade vinduer, døre, luger og lignende stå mere eller mindre åbne, og af den art, som består af en ved den ene ende svingeligt lejret spærrestang, der kan for-5 skydes og spærres i et separat spærrebeslag, der er udstyret med mindst én spærretap, og hvor spærrestangen har mindst ét langsgående spor, der direkte slutter sig til en række spærrelejer, i hvilket spor spærretappen er fanget under beslagets funktion, og hvori spærretappen kan 10 forskydes i langsgående retning og ved en tværgående forskydning spærres i et ønsket spærreleje.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjustable extension bracket which allows windows, doors, hatches and the like to be left more or less open, and of the kind which consists of a locking bar which can be slidably swiveled and locked at one end. in a separate locking bracket which is equipped with at least one locking pin and wherein the locking rod has at least one longitudinal groove directly joining a series of locking bearings, in which groove the locking pin is caught during the operation of the bracket and wherein the locking pin can be displaced in the longitudinal direction. and at a transverse displacement is locked into a desired locking bearing.

Der kendes forskellige variationer af beslag af ovenstående art, hvormed man kan stille vinduer, luger, døre og lignende åbne med forskellige åbningsvinkler enten helt trinløst eller 15 i forskellige trin ved hjælp af spærreorganer, som virker sam- men med spærrelejer langs spærrestangen.Various variations of fittings of the above kind are known by means of which windows, doors, doors and the like can be opened with different opening angles either completely steplessly or 15 in different steps by means of locking means which act together with locking bearings along the locking bar.

Eftersom man gerne vil have en mulighed for helt at kunne frikoble spærrestangen, for at man frit kan svinge vinduet eller lignende til andre ønskede åbningsvinkler, der er stør-20 re end de, der repræsenteres ved de forskellige spærrestillinger, er mange af de tidligere kendte konstruktioner udført, så spærrestængeme. gennem specielle anordninger med lethed kobles fri fra et tilhørende spærrebeslag.Since one would like to be able to completely disengage the locking bar so that one can freely swing the window or the like to other desired opening angles larger than those represented by the different locking positions, many of the prior art constructions done, then the barriers. by special devices easily disengage from an associated locking bracket.

Når det gælder fremstillingen af en vindueskrog eller lignende 25 med en konstruktion, som kun tillader åbning af vinduet eller lignende til en maksimal åbningsvinkel, tager man i første række hensyn til mindreårige børn. Ud fra andre synspunkter - f.eks, af hensyn til vinduespudsning eller lignende - er det normalt ikke tilfredsstillende med en spærrekrog, der 30 til stadighed hindrer vinduets eller et tilsvarende organs helt frie oplukning uafhængigt af spærrekrogen. Vinduet bør dog kun kunne lukkes helt frit op af voksne personer, som har tilstrækkeligt omdømme til at indse alle de risici, som også forekommer i forbindelse med vinduer, luger osv., som frit kan 145703 2 lukkes helt op. Som en naturlig konsekvens heraf er der fremkommet et ønske om, at et vinduesbeslag og lignende skal være således konstrueret, at det kan bringes både ud af og på ny ind i spærring efter en fremgangsmåde, der bør 5 være indrettet således, at en helt fri oplukning ikke kan ske utilsigtet.In the case of the manufacture of a window hull or the like with a structure which only allows the window or the like to be opened to a maximum opening angle, first of all children are taken into consideration. From other points of view - for example, for the purposes of window cleaning or the like - it is usually not satisfactory for a locking hook which constantly prevents the window or a similar body's completely free opening independently of the locking hook. However, the window should only be able to open completely freely by adults who have sufficient reputation to realize all the risks that also occur with windows, hatches, etc., which are freely open. As a natural consequence, there has been a desire for a window bracket and the like to be designed so that it can be brought out and re-locked both according to a method which should be arranged so that a completely free opening up cannot happen unintentionally.

Ved løsningen af de ovennævnte problemer har man samtidigt krævet, at manipuleringen af spærrekrogen skal være så let og bekvem - -med anvendelse af et minimum af kræfter - at 10 endog bevægelseshæmmede og på anden måde handicappede personer skal kunne indkoble og frikoble spærrekrogen uden vanskelighed.At the same time, solving the above problems has demanded that the locking hook manipulation be so easy and convenient - using a minimum of forces - that even disabled and otherwise disabled persons must be able to engage and disengage the locking hook without difficulty.

Formålet roed opfindelsen er følgelig at løse ovenstående problemer og at eliminere de antydede ulemper, dvs. anvise 15 en anordning til frikobling og indkobling af spærrestangen i forhold til spærrebeslaget, idet denne anordning i og for sig forudsætter en overlagt og kompetent manipulering af beslaget, for at frikobling overhovedet skal kunne ske.Accordingly, the object of the invention is to solve the above problems and to eliminate the disadvantages, i.e. 15 discloses a device for decoupling and switching on the locking rod relative to the locking bracket, since this device in itself requires a deliberate and competent manipulation of the bracket, in order to be able to release at all.

Dette formål opnås ved at udforme et indstilleligt udskyder-20 beslag af den indledningsvist nævnte art, som anført i krav l's kendetegnende del. Gennem denne udformning opnås, at spærrestangen let indføres i spærrebeslaget, når de har været koblet fri af hinanden, hvorefter spærretappene gennem det stive spærrebeslag giver en relativ sikker fastholdelse 25 af spærretappene i sporet.This object is achieved by designing an adjustable extension bracket of the type mentioned initially, as set forth in the characterizing part of claim 1. By this design, the locking rod is easily inserted into the locking bracket when they have been released from one another, after which the locking pins through the rigid locking bracket provide a relatively secure retention of the locking pins in the groove.

Gennem udformningen, der anvises i krav 2’s kendetegnende del, opnås at kantpartierne fanger spærreorganet i forsænkningen i alle mellemstillinger langs spærreorganet, og det tværgående oprejste kantparti ved enden af forsænkningen 30 danner stop, når vinduet stilles med den maksimale åbningsvinkel , I krav 3 og 4's kendetegnende del anvises udførelsesformer 3 145703 for spærrebeslaget.Through the design shown in the characterizing part of claim 2, the edge portions obtain the locking means in the recess in all intermediate positions along the locking means, and the transverse upright edge portion at the end of the recess 30 stops when the window is set at the maximum opening angle, in claims 3 and 4 In the characterizing part, embodiments 3 145703 for the locking bracket are disclosed.

I krav 5, 6 og 11's kendetegnende del anvises en udformning, så spærrestangen under indføring i spærrebeslaget kan virke som vægtstang, og det plovlignende organ let kiler tappene 5 fra hinanden under indkoblingen.In the characterizing part of claims 5, 6 and 11, a design is provided so that, during insertion into the locking bracket, the locking rod can act as a lever, and the plow-like member easily wedges the pins 5 apart during the engagement.

Gennem den specielle udformning, der anvises i krav 7, 8 og 10’s kendetegnende dele, opnås, at stangen kan svinges ud og frigøres fra spærrebeslaget, når stangen er indstillet, så spærretappene ligger udfor en udskæring midt udfor en mellemvæg mellem ved siden af hinanden liggende spærrelejer.Through the special design disclosed in the characterizing parts of claims 7, 8 and 10, it is achieved that the rod can be swung out and released from the locking bracket when the rod is adjusted so that the locking pins lie opposite a cut in the middle of an intermediate wall between adjacent block bearings.

Krav 12's kendetegnende del anviser en fordelagtig udformning af spærrestangen.The characteristic part of claim 12 discloses an advantageous design of the locking rod.

Opfindelsen forklares nærmere i det efterfølgende under henvisning til det på den medfølgende tegning skematisk 15 viste udførelseseksempel, og i forbindelse hermed vil yderligere blive angivet de for opfindelsen kendetegnende egenskaber.The invention will be explained in greater detail below with reference to the exemplary embodiment illustrated schematically in the accompanying drawing, and the characteristics of the invention will be further indicated.

Fig. 1 viser et vandret snit i en dørkarm, vindueskarm eller lignende samt en herved svingeligt lejret dør, luge, vindues-20 ranrne eller lignende tilligemed et indstilleligt udskyderbeslag, som står i en af de spærrende stillinger, fig. 2 viser i større målforhold og set fra oven en spærrestang ifølge opfindelsen, der svingeligt er lejret i et beslag, 25 fig. 3 viser et tværsnit efter linien III-III i fig. 2, fig. 4 viser et tværsnit efter linien XV-IV i fig, 2, fig. 5 viser et tværsnit efter linien V-V i fig. 2, 145703 4 fig. 6 viser set forfra et spærrebeslag, der virker sammen med spærrestangen, og fig. 7 viser delvis i snit og set fra højre i fig. 6 samme beslag.FIG. 1 shows a horizontal section of a door frame, window sill or the like, and a pivotally mounted door, hatch, window rails or the like, as well as an adjustable slider bracket which is in one of the locking positions; FIG. Figure 2 shows, in larger dimensions and from above, a locking bar according to the invention pivotally mounted in a bracket; 3 shows a cross section along line III-III in FIG. 2, FIG. 4 is a cross-sectional view taken along line XV-IV of FIG. 2; FIG. 5 shows a cross section along the line V-V in FIG. 2, FIG. 6 shows a front view of a locking bracket which works with the locking bar, and FIG. 7 is a partial sectional view from the right of FIG. 6 same fittings.

5 På tegningen er en karm betegnet med 10 og en ramme, f.eks. en vinduesramme, med 11, idet rammen ved hjælp af hængsler 12 er svingeligt lejret ved karmens ene lodrette side.5 In the drawing, a frame is indicated by 10 and a frame, e.g. a window frame, with 11, the frame by hinges 12 being pivotally mounted at one vertical side of the frame.

Ved karmen 10fs nedre part er på kendt måde fastgjort et lejebeslag 13, hvori en spærrestang 14 er svingeligt lejret om-10 kring en lodret tap 15. Spærrestangen 14 vises i hovedsagen i sin yderste spærrende stilling indført i et fast spærre-beslag 16, der sidder på den nedre del af vindueskarmen eller lignende organer.In the known manner, a bearing bracket 13 is secured to the lower part of the frame 10f, in which a locking bar 14 is pivotally mounted about a vertical pin 15. The locking bar 14 is generally shown in its outermost locking position inserted in a fixed locking bracket 16 which sitting on the lower part of the window sill or similar organs.

Spærrestangen 14 er normalt spærret således i spærrebeslaget 15 16, at vinduet 11 eller lignende organer kun kan svinges en maksimal vinkel bort fra karmen, f.eks, vinklen a, der svarer til en horisontal åhningsdistance A for vinduet, hvilken afhænger af lejebeslaget 13's og tappen 15's monteringsafstand fra hængslerne 12, og som derfor kan tilpasses ved det 20 indstillelige udskyderbeslags montering ved vinduet. Sædvanligvis begrænser man denne afstand således, at man får en risikofri åbning af vinduet med hensyn til mindreårige børn.The locking bar 14 is normally locked so in the locking bracket 16 that the window 11 or similar means can only be pivoted a maximum angle away from the frame, for example, the angle a corresponding to a horizontal opening distance A of the window which depends on the bearing bracket 13's and the mounting distance of the pin 15 from the hinges 12, which can therefore be adjusted by the mounting of the adjustable extension bracket at the window. This distance is usually limited to a risk-free opening of the window with respect to minor children.

Inden for drejningsvinklen α er vinduesrammen med henblik på udluftning indstillelig i forskellige vinkler ved, at 25 spærrestangen 14 er forsynet med et antal spærrelejer i spærrestangens længderetning. Spærrestangen vil senere blive beskrevet i forbindelse med fig. 2.Within the angle of rotation α, the window frame for ventilation is adjustable at different angles in that the locking bar 14 is provided with a number of locking bearings in the longitudinal direction of the locking bar. The locking bar will later be described in connection with FIG. 2nd

Den i fig, 1 med fuldt optrukne linier viste foretrukne udførelsesform for det indstillelige udskyderbeslag viser 30 spærrestangen i en af dens spærrestillinger, nærmere bestemt i yderste spærrestilling.The preferred embodiment of the adjustable slider bracket shown in FIG. 1 in Fig. 1 shows the locking rod in one of its locking positions, more specifically in the outermost locking position.

Den på tegningen viste foretrukne udførelsesform skal i nedenstående nærmere forklares under henvisning til fig. 2-7.The preferred embodiment shown in the drawing will be explained in more detail below with reference to FIG. 2-7.

Fig. 2 viser den i fig. 1 med 14 betegnede spærrestang i større målforhold. Spærrestangen 14 er som i fig. 1 svinge-5 ligt lejret omkring tappen 15 i lejebeslaget 13 med en bue-formig, knælignende part 18 og fortsætter herfra i en relativ lang, lige stangdel, som slutter i et fingergreb 19 til spærrestangens manøvrering.FIG. 2 shows the one in FIG. 1 with 14 designated locking bar in larger target conditions. The locking bar 14 is as in FIG. 1 is pivotally mounted around the pin 15 of the bearing bracket 13 with an arcuate, knee-like portion 18 and proceeds thence in a relatively long, straight rod portion ending in a finger grip 19 for locking bar maneuvering.

Som det fremgår af fig. 2 - 5, er spærrestangen 14 på hver 1Q af de to modstående sider udstyret med en langsgående forsænkning eller et spor 20, som langs den ene langside og ved fingergrebet begrænses af opstående kantpartier 21 respektive 22 og langs den anden langside af en kam-profileret væg 23 med kamtænder 24, der er afrundet i spidserne, imellem hvilke 15 spærrestangens spærrelejer 25 afgrænses. De opretstående kantpartier 21, 22 og 23 tjener til at hindre de i forsænkningen 20. forskydelige spærretappe 36 og 37 i spærrebeslaget 16 i utilsigtet at forlade forsænkningen 20. Ved indgangene til disse spærrelejer er anordnet tærskler 26 med lavere højde 20 end den kam-profilerede væg 23.As shown in FIG. 2 to 5, the locking bar 14 on each 1Q of the two opposite sides is provided with a longitudinal recess or groove 20 which, along one long side and at the finger grip, is constrained by upright edge portions 21 and 22, respectively, and along the other long side of a cam profiled wall 23 with comb teeth 24 rounded at the tips between which the locking bearings 25 of the locking rod are bounded. The upright edge portions 21, 22 and 23 serve to prevent the sliding tabs 36 and 37 of the locking bracket 16 sliding in the recess 20 inadvertently leaving the recess 20. Thresholds 26 of lower height 20 are provided at the entrances to these locking bearings. wall 23.

Videre må det nævnes, at forsænkningerne 20 ved de ender, der vender ud mod spærrestangens bueformede knælignende part ved den viste udførelsesform, savner en tværgående opstående begrænsningskant, hvilket på grund af krogens monterings-25 form her skulle savne praktisk betydning, men som meget vel kunne være anordnet på dette sted for fuldstændigt at lukke forsænkningen 20 ved denne ende af stangen.Further, it should be mentioned that the recesses 20 at the ends facing the arcuate knee-like part of the bar of the bar shown in the illustrated embodiment lack a transverse raised limiting edge, which, due to the mounting shape of the hook here, should miss practical significance, but as well could be provided at this location to completely close the recess 20 at this end of the bar.

Som det videre fremgår af fig. 1, 2 og 3, er der i forlængelse af begrænsningskanterne i overgangszonen mellem den bueformede 30 part 18 og den lige part af spærrestangen anordnet at kile- fcrmigt eller plovlignende organ 27. Dette plovlignende organ 27's frie ende 27a er i hovedsagen placeret i et plan, der ligger forskudt i forhold til et dermed parallelt aksial-plan gennem drejningsaksen, dvs. gennem aksen, der går 145703 6 gennem tappen 15's centrum, og som ligger i retning mod den lige stangpart. Det har i praksis vist sig, at plovorganets ende 27a bør ligge i et plan, som ikke passerer gennem tappen, men som ligger i en afstand fra denne, hvilken afstand 5 bør kunne justeres i forhold til spærrebeslagets spærreorgan. Videre kan nævnes, at i det viste eksempel svarer godstykkelsen i den bueformede eller knælignende part 18 til afstanden mellem de to bunde i forsænkningerne 20, hvorved forsænkningerne samtidig har en form, der minder om en 10 lomme med åbningen liggende i nævnte overgangs zone..As further shown in FIG. 1, 2 and 3, by extension of the boundary edges of the transition zone between the arcuate 30 portion 18 and the straight portion of the barrier rod, there is arranged to wedge-shaped or plow-like member 27. The free end 27a of the plow-like member 27 is substantially located in a plane. , which is offset relative to a parallel axial plane through the axis of rotation, i. through the axis passing through the center of the pin 15 and which is in the direction of the straight rod portion. In practice, it has been found that the end of the plow member 27a should lie in a plane which does not pass through the pin, but which is at a distance from it, which distance 5 should be adjustable in relation to the locking means of the locking bracket. Furthermore, it can be mentioned that in the example shown, the thickness of the arch-shaped or knee-like part 18 corresponds to the distance between the two bottoms of the recesses 20, whereby the recesses have a shape resembling a pocket with the opening lying in said transition zone.

Med hensyn til fig. 2 og 4 må bemærkes, at de rejste kanter 21 på et sted er afbrudt med udskæringerne 28, som hver er forsynet med en tærskelpart 29. Af disse figurer fremgår, at disse udskæringer begge i hovedsagen er placeret ud for 15 midten af en kamtand eller mellemvæg 30 mellem to spærrelejer. Kamtanden hgr en noget større bredde i sideretningen end de øvrige kamtænder 24, hvilket dog ikke kan ses i fig. 2. Årsagen hertil vil fremgå af nedenstående.With regard to FIG. 2 and 4, it should be noted that at one point the raised edges 21 are interrupted by the cut-outs 28, each provided with a threshold portion 29. It can be seen from these figures that these cut-offs are essentially located outside the middle of a tooth tooth or partition wall 30 between two locking bearings. The comb tooth has a somewhat greater width in the lateral direction than the other comb teeth 24, which however can not be seen in fig. 2. The reason for this will be stated below.

I fig. 6 og 7 vises separat spærrebeslaget 16, som virker 20 sammen med spærrestangen. Det består i hovedsagen af en klods-formet part 31 med gennemgående skruehuller 32, der er forsænket fra begge sider, eftersom det er tilsigtet, at spærrebeslaget i lighed med spærrestangen 14 tilligemed lejebeslaget 13 efter ønske skal kunne vendes, for at det kan bru-25 ges ved såvel højrevendte som venstrevendte vinduer. Af samme årsag er der i et symmetriplan gennem klodsen 31 anordnet et bøjleorgan 39 med et åbent gab 33, hvis kæbeparter 34 og 35 er udstyret med hver sit spærreorgan, i det viste eksempel et tapformet i snit cirkulært organ 36 respektive 37. Disse 3Q to tappe begrænser tilsammen gabet 33's effektive vidde til en værdi, som, når spærrestangen i lighed med det i fig. 1 viste, er indført i spærrebeslagets gab, og tappene fra hver sin side er fanget i hver sin forsænkning 20 i spærrestangen, bidrager til at hindre, at tappene kan gå ud af disse for-35 sænkninger. Sektionen med disse tappe er tilpasset således, • 7 145703 at tappene kan passere ind i og langs forsænkningerne, kan indføres i spærrestangens spærrelejer og desuden kan passere gennem de respektive udskæringer 28 i de rejste kantpartier 21.In FIG. 6 and 7 are shown separately the locking bracket 16 which acts 20 together with the locking rod. It consists essentially of a bell-shaped portion 31 with through-hole holes 32 recessed from both sides, since it is intended that the locking bracket, like the locking rod 14, as well as the bearing bracket 13, can be turned in order to use it. 25 is provided on both right-hand and left-hand windows. For the same reason, in a plane of symmetry through the block 31, a bracket member 39 is provided with an open gap 33, the jaw portions 34 and 35 of each having a locking means, in the example shown, a tab shaped in section circular means 36 and 37 respectively. together, the pin limits the effective width of the gap 33 to a value which, when the locking rod is similar to that of FIG. 1 is inserted into the gap of the locking bracket, and the pins on each side are trapped in each recess 20 in the locking rod, helping to prevent the pins from exiting these depressions. The section with these pins is adapted so that the pins can pass into and along the recesses, can be inserted into the locking bar locking bearings and can also pass through the respective cut-outs 28 in the raised edge portions 21.

5 Spærrebeslagets gab 33 bar - når undtages, hvor de tapformede organer 36 og 37 sidder - en højde, som i det væsentlige svarer til spærrestangens maksimale tykkelse, så at stangen med i det mindste et vist spillerum kan optages mellem gabets kæbepar 34 og 35. De tapformede spærreorganer er ved 10 det foretrukne udførelseseksempel anordnet således i spærrebeslaget, at gennem en ekstra kraftindsats er den ene eller begge til en vis grad eftergivende i spærrebeslaget, og derved muliggøres en tvangsmæssig ind- og udsvingning af stangen i forhold til gabet 33.5 The bar 33 of the locking bracket - when exempted where the tab-shaped members 36 and 37 are seated - is a height which substantially corresponds to the maximum thickness of the locking bar, so that the bar with at least some clearance can be accommodated between the jaw pairs 34 and 35 of the bar. The pin-shaped locking means are arranged in the preferred embodiment in the locking bracket in such a way that, through an extra force insertion, one or both of them are, to a certain extent, resilient in the locking bracket, thereby enabling a forced swing-in of the bar relative to the gap 33.

Hvis spærrestangen 14 fra den helt frikoblede stilling, som 15 det i fig, 1 er vist med de stiplede linier 17, skal kunne sammenkobles spærrende med spærrebeslaget 16, svinger man vinduet eller tilsvarende organ til lukket stilling, så at gabet 33's åbning og tappene 36 og 37 fra siden kommer hen foran plovorganet 27 (se fig. 2 og 3), hvorefter plovorganet 20 tvinger i det mindste en tap til at give efter, til kanterne 38 på plovorganet 27 helt er passeret af tappene, og tappene er fanget i forsænkningerne 20 bag ved plovorganet 27. Dimensioneringen og placeringen af de derved samvirkende organer er ved en foretrukken udførelsesform således, at tappenes 25 indsnapning sker automatisk ved vinduets lukning.If the locking bar 14 from the fully disengaged position, as shown in FIG. 1 in Fig. 1, is to be able to be interlocked with the locking bracket 16, the window or similar means is closed to the closed position so that the opening of the gap 33 and the pins 36 and 37 from the side come in front of the plow member 27 (see Figs. 2 and 3), after which the plow member 20 forces at least one pin to yield until the edges 38 of the plow member 27 are completely passed by the pins and the pins are trapped in the recesses. 20, at the rear of the plow member 27. The dimensioning and positioning of the cooperating means thereby is in a preferred embodiment such that the snap-in of the pins 25 takes place automatically at the closing of the window.

Når det siden ønskes at koble spærrestangen fri fra spærrebeslaget 16, åbner man vinduet eller tilsvarende organer til en sådan stilling, at tappene 36 og 37 kommer i position, hvor de står ud for udskæringerne 28 og de specielt udfor-30 mede kamtænder 30, og i denne stilling manipulerer man således med stangen, at denne under styring af tappene forbi tænderne 30 i en bestemt stilling tillader, at disse tappe 36 og 37 kan forlade forsænkningerne 20 gennem udskæringerneWhen it is then desired to disconnect the locking bar from the locking bracket 16, the window or similar means is opened to such a position that the pins 36 and 37 come into position where they face the cutouts 28 and the specially shaped cam teeth 30, and in this position one is manipulated with the rod so that under the control of the pins past the teeth 30 in a certain position, these pins 36 and 37 can leave the recesses 20 through the cuts

Claims

28. To prevent this from happening too easily, the thresholds 29 (see Fig. 4) have been provided, which force the pins to yield while generating some resistance to the pin movement movement. Thus, on the one hand, the position of pins 26 and 37 and the cuts 29 must be in a predetermined relative position, and in addition the decoupling maneuver must be carried out with an extra force effort. The same principle is used at the thresholds 26 during the insertion and execution of the locking positions of the pins 25. 1Q Although the illustrated embodiment of the adjustable slider bracket may of course be preferred because the slider bracket can be utilized for windows, which both open up to appropriate windows. Of course, right and left, it is also possible to carry out the construction for one of the alternatives.
