Titel: Åbnemekanisme til en ventilationsåbning Frembringelsens områdeTitle: Opening mechanism for a vent opening The area of production
Den foreliggende frembringelse angår en ventilationsåbning af den type, der indbygges i tagkonstruktioner og som typisk omfatter en karmdel og en lågdel, hvor denne lågdel ved brand eller røgudvikling åbnes ved en forkant og er hængslet til karmdelen ved en modstående hængsellinie og derved anvendes til ventilation af et lokale, hvor lågdelen under normale forhold anvendes til komfortventilation, hvor ventilationsåbningen er med mekaniske midler, der er monteret imellem karm dele, som forløber parallelt med hængsellinien, hvor de mekaniske midler omfatter mindst én styret lineær aktuator, hvor den lineære aktuator er forbundet mellem en tværvange og mindst en løftearm for åbning af ventilationsåbningen, og hvor aktivering af åbningen sker manuelt eller automatisk med de nævnte mekaniske midler.The present invention relates to a ventilation opening of the type which is built into roof structures and which typically comprises a frame part and a lid part, where this lid part is opened by a fire or smoke development at a leading edge and is hinged to the frame part by an opposite hinge line and is thereby used to ventilate the a room where, under normal conditions, the cover portion is used for comfort ventilation, the ventilation opening being with mechanical means mounted between frame members extending parallel to the hinge line, wherein the mechanical means comprises at least one controlled linear actuator where the linear actuator is connected between a cross member and at least one lifting arm for opening the ventilation opening and wherein the opening of the opening is done manually or automatically by said mechanical means.
Beskrivelse af kendt teknikDescription of prior art
Ventilationsåbninger eller ventilationsvinduer til indbygning i tagkonstruktioner har været kendt i mange år og mange forskellige udførelsesformer har været udbudt. I de senere år er der blevet stillet stadig højere krav til ventilation i forbindelse med brand eller røgudvikling i erhvervsbygninger, såvel industribygninger som kontorbygninger. Ligeledes er der med den moderne byggestil, hvor der anvendes glasfacader og store vinduespartier opstået et øget behov for komfortventilation. Dette klares mange steder med mekanisk udskiftning af luften men hvor det er muligt, anvendes de installerede ventilationsåbninger ofte som en mulighed for at forbedre indeklimaet.Ventilation openings or ventilation windows for incorporation into roof structures have been known for many years and many different embodiments have been offered. In recent years, increasing demands have been made for ventilation in connection with fire or smoke development in commercial buildings, both industrial buildings and office buildings. Also, with the modern building style, where glass facades and large window sections are used, there is an increased need for comfort ventilation. This is done in many places with mechanical air replacement but where possible, the installed ventilation openings are often used as an opportunity to improve the indoor climate.
I den daglige anvendelse, hvor ventilationsåbningen anvendes til komfortventilation, betyder åbnehastigheden ikke så meget, men i tilfælde af røgudvikling fra en brand eller lignende er det vigtigt, at ventilationsåbningen kan åbne hurtigt og med en tilstrækkelig åbningsvinkel. Denne åbning skal kunne ske med den påkrævede hastighed uanset om det er blæsevejr, om der ligger sne på ventilationsåbningen eller om der er andet der tynger vinduet. Derfor er kendte typer af ventilationsåbninger fremstillet med sindrige mekaniske åbnemekanismer, typisk med to eller flere kraftige aktuatorer, der er drevet elektrisk eller med trykluft eller med kombinationer af elektricitet og trykluft, som er forbundet i forlængelse af hinanden. Andre varianter er med kun én 2 DK 2008 00116 U3 aktiiator, livor aktuatoren er så lang, at den uden videre kan åbne ventilationsåbningen. Disse mekanismer er ofte noget markante og eksempelvis kan sådanne løsninger være med en åbnemekanisme, der strækker sig et godt stykke ned i rummet under ventilationsåbningen. En sådan løsning er ikke diskret og pæn og nutidens arkitekter, ingeniører og ikke mindst kunder forventer løsninger, der er mere diskrete og elegante, samtidig med, at ventilationsåbningen kan åbne hurtigt og effektivt med den ønskede og/eller påkrævede åbnings vinkel.In daily use, where the ventilation opening is used for comfort ventilation, the opening speed does not mean much, but in the case of smoke evolution from a fire or the like, it is important that the ventilation opening can open quickly and with a sufficient opening angle. This opening must be possible at the required speed, whether it is windy, whether there is snow on the ventilation opening or if there is anything else that weighs the window. Therefore, known types of ventilation openings are made with ingenious mechanical opening mechanisms, typically with two or more powerful actuators driven electrically or with compressed air or by combinations of electricity and compressed air connected in extension. Other variants are with only one 2 actuator, the livor actuator is so long that it can open the ventilation opening. These mechanisms are often somewhat marked and, for example, such solutions may be provided with an opening mechanism extending well into the space below the ventilation opening. Such a solution is not discreet and neat, and today's architects, engineers and, not least, customers expect solutions that are more discreet and elegant, while allowing the vent to open quickly and efficiently at the desired and / or required opening angle.
Det er formålet med frembringelsen at angive en ventilationsåbning, der lever op til de krav nutiden stiller, der er robust, med høj åbnehastighed, stor åbningsvinkel og som samtidig kun optager minimal plads og ikke fremstår dominerende.The purpose of the production is to specify a ventilation opening that meets the requirements of the present, which is robust, with high opening speed, large opening angle and which at the same time occupies only minimal space and does not appear dominant.
Beskrivelse af frembringelsenDescription of the production
Frembringelsen angår som nævnt indledningsvist en ventilationsåbning med mekaniske midler, der omfatter mindst én styret lineær aktuator, hvor aktuatorens bevægelsesretning fortrinsvist er væk fra forkanten, hvor aktuatoren er drejeligt fikseret til en tværvange, fortrinsvist ved den ene ende og er forbundet til en stangmekamsme fortrinsvist ved den anden ende, hvor stangmekanismen via et bevægeligt leje er forbundet til et forskydningsleje/glidespor, der er i fast forbindelse med ventilationsåbningens lågdel. Med en sådan ventilationsåbning opnås der en løsning, hvor en aktuator med en forholdsvis ringe slaglængde kan anvendes til åbning af selv store ventilationsåbninger. Der er med denne løsning en optimal udnyttelse af de kræfter, der er til rådighed fra aktuatoren, da angrebspunktet på iågdelen hele tiden flyttes efterhånden som ventilationsåbningen åbnes eller lukkes. Dette opnås med frembringelsen ved, at der anvendes et forskydningsleje/glidespor mellem mekanisme og lågdel.The production, as mentioned, initially relates to a ventilation opening by mechanical means comprising at least one controlled linear actuator, the direction of movement of the actuator preferably away from the leading edge, the actuator being pivotally fixed to a transverse bar, preferably at one end and connected to a rod cam preferably at the other end, where the rod mechanism is connected via a movable bearing to a displacement bearing / sliding track which is firmly connected to the lid portion of the ventilation opening. With such a ventilation opening, a solution is obtained in which an actuator with a relatively small stroke can be used to open even large ventilation openings. With this solution, there is an optimal utilization of the forces available from the actuator, as the point of attack on the lower part is constantly moved as the ventilation opening is opened or closed. This is achieved with the production by using a shear bearing / sliding track between mechanism and cover part.
I en foretrukken udførelsesform af en ventilationsåbning ifølge frembringelsen kan den nævnte stangmekanisme omfatte en første momentarm, hvortil aktuatoren er bevægeligt lejret, hvor den første momentarm er drejeligt fikseret ved sin ene ende til tværvangen og hvor der til momentarmen yderligere er drejeligt lejret en første løftearm, hvor den første løftearm yderligere er med et forskydningsleje, der står i forbindelse med et forskydningsleje/glidespor i fast forbindelse med lågdelen. Denne løsning angiver en mekanisme med én enkelt løftearm og er specielt egnet til ventilationsåb- 3 DK 2008 00116 U3 ninger med en ringe størrelse, hvor der ikke virker så store ydre belastninger på. Der kan således fremstilles en simpel mekanisme ifølge opfindelsen til de ventilationsåbninger, der ikke kræver så stor en kraft for at åbnes.In a preferred embodiment of a vent opening according to the invention, said rod mechanism may comprise a first torque arm to which the actuator is movably mounted, the first torque arm being pivotally fixed at one end to the transverse arm and to the torque arm further rotatably bearing a first lifting arm. wherein the first lifting arm is further provided with a shear bearing which is associated with a shear bearing / sliding track in fixed connection with the cover portion. This solution specifies a single lifting mechanism and is particularly suitable for ventilation openings of a small size, where no such large external loads act. Thus, a simple mechanism according to the invention can be produced for those ventilation openings which do not require as much force to open.
En foretrukken udførelsesform omfatter en ventilationsåbning, hvor nævnte stangmekanisme omfatter en første momentarm, hvortil aktuatoren er bevægeligt lejret, hvor den første momentarm er drejeligt fikseret ved sin ene ende til tværvangen og hvor der til momentarmen yderligere er drejeligt lejret en første løftearm. hvor den første løftearm yderligere er forbundet til en anden løftearm, hvor den anden løftearm er bevægeligt lejret til tværvangen og yderligere er med et forskydningsleje, der står i forbindelse med et forskydningsleje/glidespor i fast forbindelse med lågdelen. Ved at anvende endnu en løftearm opnås der den fordel, at en endnu mere optimeret løsning opnås med hensyn til kræfter til åbning af en ventilationsåbning, samt at en aktuator med en given slaglængde i princippet kan åbne ventilationsåbninger, der er endnu større.A preferred embodiment comprises a ventilation opening, wherein said rod mechanism comprises a first torque arm to which the actuator is movably mounted, the first torque arm being pivotally fixed at one end to the transverse arm, and to which the torque arm is further pivotally mounted a first lifting arm. wherein the first lifting arm is further connected to a second lifting arm, the second lifting arm being movably mounted to the transverse arm and further having a shear bearing which communicates with a shear bearing / sliding track in fixed connection with the lid part. By using yet another lifting arm, the advantage is obtained that an even more optimized solution is obtained in terms of forces for opening a ventilation opening, and that an actuator with a given stroke can in principle open ventilation openings which are even larger.
I en anden foretrukken variant af frembringelsen er den mindst ene styrede aktuator suppleret af yderligere mindst én anden aktuator, fortrinsvist af gasfjeder typen, hvor den yderligere mindst ene anden aktuator er arrangeret mellem tværvangen og en løftearm således, at der i det mindste udøves en løftekraft på ventilationsåbningens lågdel under den første del af åbningen, fortrinsvist indtil ventilationsåbningen er mindst 60 grader åben. Med denne udførelse opnås der en øget sikkerhed i forbindelse med snelaster, vindlaster eller andet der kan påvirke og modvirke åbning af ventilationsåbningen. Alternativt kan en given aktuator anvendes til en større ventilationsåbning, idet den suppleres af yderligere en aktuator/gasfjeder.In another preferred variant of the production, the at least one controlled actuator is supplemented by at least one other actuator, preferably of the gas spring type, wherein the further at least one other actuator is arranged between the cross member and a lifting arm such that at least one lifting force is exerted. on the cover portion of the vent opening during the first portion of the opening, preferably until the vent opening is at least 60 degrees open. With this design, an increased safety is achieved in connection with snow loads, wind loads or other things that can affect and counteract the opening of the ventilation opening. Alternatively, a given actuator can be used for a larger ventilation opening, supplemented by an additional actuator / gas spring.
Ved at placere denne mindst ene anden aktuator mellem tværvange og løftearm opnås det, at der også ved lukning af ventilationsåbningen udøves en løftekraft på ventilationsåbningens lågdel, i det mindste under den første del af lukningen, fortrinsvist indtil lågdelen kun er 90 grader åben. Således gives der et krafttilskud netop på de tidspunkter, hvor det er allermest nødvendigt og hvor egenvægten af ventilationsåbningens lågdel skal løftes fri af karmdelen eller lukkes i efter endt ventilation.By placing this at least one other actuator between the cross member and the lifting arm, it is achieved that even when closing the ventilation opening, a lifting force is exerted on the lid part of the ventilation opening, at least during the first part of the closure, preferably until the lid part is only 90 degrees open. Thus, a power supplement is given precisely at the times when it is most necessary and where the intrinsic weight of the lid opening of the ventilation opening must be lifted free of the frame part or closed in after the ventilation is completed.
4 DK 2008 00116 U34 DK 2008 00116 U3
En ventilationsåbning ifølge frembringelsen kan med fordel være indrettet således, at den mindst ene aktuator er forbundet med et system af en eller flere yderligere aktuato-rer i andre ventiiationsåbninger, hvor disse aktuatorer styres og reguleres via en eller flere styrings- og reguleringsenheder. Det er således muligt at betjene flere ventilationsåbninger på én gang og således hurtigt opnå en effektiv ventilation.Advantageously, a ventilation opening according to the invention may be arranged so that the at least one actuator is connected to a system by one or more additional actuators in other ventilation openings, where these actuators are controlled and controlled via one or more control and regulation units. Thus, it is possible to operate multiple ventilation openings at one time and thus achieve efficient ventilation quickly.
En foretrukken variant af frembringelsen omfatter en ventilationsåbning, hvor aktuator og stangmekanisme er arrangeret ved den ende af tværvangen, der er tættest på hæng-sellinien, hvor tværvangen således er længdetilpasselig ved den anden ende. Hermed er det muligt at anvende en standard mekanisme til forskellige størrelser af ventilati-onsåbninger, da der blot kan skæres af den ene ende af tværvange og glidesporet til lågdelen for at tilpasse til den aktuelle ventilationsåbning.A preferred variant of the production comprises a vent opening, wherein the actuator and rod mechanism are arranged at the end of the cross bar closest to the hinge line, the cross bar being thus length-adjustable at the other end. Hereby, it is possible to use a standard mechanism for different sizes of ventilation openings, since one can only be cut by one end of the cross member and the sliding groove to the lid part to fit the current ventilation opening.
En ventilationsåbning ifølge frembringelsen kan være udført således, at den mindst ene aktuator er en elektrisk drevet aktuator, en pneumatisk drevet aktuator eller en hydraulisk drevet aktuator. Uanset hvilken type af aktuator der anvendes, kan den suppleres af eksempelvis en eller flere gasfjedre, der er arrangeret således, at disse udøver en kraft, der hjælper til henholdsvis at åbne og lukke lågdelen.A vent opening according to the invention may be designed such that the at least one actuator is an electrically driven actuator, a pneumatically driven actuator or a hydraulically driven actuator. Regardless of the type of actuator used, it can be supplemented by, for example, one or more gas springs arranged so that they exert a force which helps to open and close the lid part, respectively.
En ventilationsåbning ifølge frembringelsen kan åbne mindst 150 grader, og den kan være indrettet således, at lågdelen kan åbnes mindst 140 grader i forhold til karmdelen på under ét minut.A vent opening according to the invention can open at least 150 degrees and it can be arranged so that the lid part can be opened at least 140 degrees relative to the frame part in less than one minute.
En ventilationsåbning ifølge frembringelsen kan udføres på flere forskellige måder end de, der her er angivet. De omtalte varianter er alle foretrukne udførelsesformer, som en fagmand vil kunne udføre i andre varianter, der ikke er diskuteret i dette skrift. Det er dog klart, at sådanne varianter stadigvæk vil være opfattet af frembringelsens genstand.A vent opening according to the invention can be made in several different ways than those disclosed herein. The variants mentioned are all preferred embodiments that a person skilled in the art will be able to perform in other variants not discussed in this specification. However, it is clear that such variants will still be perceived by the subject of production.

Detaljeret beskrivelse af frembringelsen I fig. 1 ses en ventilationsåbning 1, der i princippet består af en karmdel 2, der er beregnet til indbygning i en tagkonstruktion, og en lågdel 3, der typisk er udført med en ramme og med lysgennemtraengeligt plademateriale som låg. Typisk er selve låget udført med en buefacon eller en anden facon, der tillader sne lettere at falde af. Lågdelen 3 er fikseret til karmdelen 2 via et hængsel 4 og mellem karmdelen 2 og lågdelen 3 er der en mekanisme 5, som er fikseret delvist til karmdelen 2 og delvist til lågdelen 3 og som kan påvirke lågdele 3 til henholdsvist åbning og lukning.Detailed Description of the Invention In FIG. 1, there is shown a ventilation opening 1, which in principle consists of a frame part 2, which is intended to be built into a roof structure, and a cover part 3, which is typically constructed with a frame and with light-permeable sheet material as a lid. Typically, the cover itself is made with an arch or other shape that allows snow to fall off more easily. The lid part 3 is fixed to the frame part 2 via a hinge 4 and between the frame part 2 and the cover part 3 there is a mechanism 5 which is fixed partly to the frame part 2 and partly to the lid part 3 and which can affect the lid parts 3 for opening and closing respectively.
I fig. 2 ses den samme mekanisme 5, som i fig. 1, men her set fra den anden side og uden karmdel 2 og lågdel 3. Ligeledes er der for lettere at kunne se og overskue mekanismen 5 fjernet dele af selve mekanismen som ellers ville dække de detaljer, der i det følgende skal beskrives. De dele, der er fjernet, er dog alle dele, som der er henholdsvis en højre og en venstre af. Der er således ikke fjernet dele fra tegningen, der kan virke meningsforstyrrende. Yderst til højre i fig. 2 ses hængslet 4 og til montering mellem de ikke viste parallelle karmdele 2 ses tværvangen 6, der ved sine ender er forsynet med monteringsflanger 7, for montering til karmen 2. Denne tværvange strækker sig på tværs i karmdelen og på denne måde opnås en god stivhed i mekanismen 5. På tværvangen 6 er der i et roterbart fikspunkt 8 fikseret en elektrisk aktuator 9, med en tilslutningsledning 10. Aktuatorens stempel 11 er fikseret til en momentarm 12 i et rotationspunkt 13. Momentarmen 12 er fikseret til tværvangen 6 tæt ved hængslet 4 i et rotationspunkt 14. På momentarmen 12 er der yderligere et rotationspunlct 15, hvortil den første løftearm 16 er fikseret. Denne første løftearm 16 er ved sin anden ende fikseret til den anden løftearm 17 i yderligere et rotationspunkt 18. Den anden løftearm 17 er ved den ene ende fikseret i rotationspunktet 19 til et beslag 20, der er stift forbundet til tværvangen 6 og er ved den anden ende i et forskydningsleje 21 forbundet til en glideskinne 22, der skal fikseres til lågdelen 3. Dette forskydningsleje 21 omfatter et glideemne, der under åbning og lukning føres frem og tilbage i glideskinnen 22, 6 DK 2008 00116 U3 hvorved angrebspunktet for den anden løftearm 17 flyttes i glideskinnen 22 alt afhængig af, hvor åben eller lukket ventilationsåbningen 1 er. Som det fremgår af figuren er der et stykke af tværvangen 6 ved den ende der er modsat hængselsiden, hvor der ikke er fæstnet noget til og dette stykke kan kortes op således, at en mekanisme 5 som den viste kan tilpasses til andre størrelser af ventilationsåbninger 1. Glideskinnen 22 skal selvsagt også afkortes og afhængigt af belastning med mere kan den anden løftearm også afkortes eller alternativt udskiftes med en kortere en af slagsen. Såvel som en afkortning kan fmde sted, så kan også en forlængelse af tværvange 6, glideskinne 22 og eventuelt den anden løftearm 17 finde sted. En sådan operation skal dog beregnes nøje for at sikre, at der er tilstrækkelig med kræfter til rådighed. I fig. 2 ses der endvidere en gasfjeder 23, der er fæstnet til beslaget 20 ved den ene ende 24 og til den anden løftearm 17 ved den anden ende 25. Denne gas fjeder 23 virker med en kraft i retning mod den anden løftearm 17 og hjælper således med at løfte glideskinnen 22 og lågdelen 3. Når glideskinnen kommer op i omkring lodret position har gasfjederen 23 udført sit arbejde og kan ikke blive længere. Ved yderligere åbning sker der en sammentrykning af gasfjederen 23 på grund af egenvægten fra lågdelen 3 og på grund af leraften fra aktuatoren 3, der således medfører, at gasfjederen 23 også hjælper til med at løfte lågdelen 3 under lukning fra en position, hvor beslaget 20 og den anden løftearm 17 flugter med hinanden.In FIG. 2 shows the same mechanism 5 as in FIG. 1, but here seen from the other side and without frame part 2 and cover part 3. Also, to be able to see and overlook the mechanism 5, parts of the mechanism itself are removed which would otherwise cover the details to be described below. However, the parts removed are all parts of which there are a right and a left respectively. Thus, no parts have been removed from the drawing which may appear to be disruptive. In the far right of FIG. 2, the hinge 4 is shown and for mounting between the parallel frames not shown 2, the cross member 6, provided at its ends with mounting flanges 7, is shown for mounting to the frame 2. This cross member extends transversely in the frame part and in this way a good stiffness is obtained. in the mechanism 5. On the cross member 6, in an rotatable fixing point 8, an electric actuator 9 is fixed, with a connection line 10. The piston 11 of the actuator is fixed to a torque arm 12 at a rotation point 13. The torque arm 12 is fixed to the cross arm 6 close to the hinge 4 in a rotation point 14. On the torque arm 12 there is a further rotation point 15 to which the first lifting arm 16 is fixed. This first lifting arm 16 is fixed at its other end to the second lifting arm 17 at a further rotation point 18. The second lifting arm 17 is fixed at one end in the rotation point 19 to a bracket 20 which is rigidly connected to the cross member 6 and is attached to it. second end of a shear bearing 21 connected to a sliding rail 22 to be fixed to the lid part 3. This shear bearing 21 comprises a sliding element which is guided back and forth in the sliding rail 22 during opening and closing, whereby the point of attack of the second lifting arm 17 is moved in the slide rail 22 depending on how open or closed the vent 1 is. As can be seen from the figure, there is a piece of the cross member 6 at the end opposite to the hinge side where there is nothing attached and this piece can be shortened so that a mechanism 5 as shown can be adapted to other sizes of ventilation openings 1 Of course, the slide rail 22 must also be shortened and depending on the load, the other lifting arm can also be shortened or alternatively replaced with a shorter one of the kind. As well as a shortening can take place, so also an extension of the cross member 6, slide rail 22 and optionally the other lifting arm 17 can take place. However, such an operation must be carefully calculated to ensure that sufficient forces are available. In FIG. 2, there is also seen a gas spring 23, which is attached to the bracket 20 at one end 24 and to the other lifting arm 17 at the other end 25. This gas spring 23 acts with a force in the direction of the other lifting arm 17 and thus helps with to lift the slide rail 22 and the lid part 3. When the slide rail reaches about a vertical position, the gas spring 23 has done its job and can no longer be. Upon further opening, the gas spring 23 is compressed due to the intrinsic weight of the lid part 3 and due to the clay evening from the actuator 3, which means that the gas spring 23 also helps to lift the lid part 3 during closing from a position where the bracket 20 and the other lifting arm 17 align with each other.
1 fig. 3 ses en mekanisme 5 magen til den, der er vist i fig. 3, men her vist i helt åben position og i fig. 4 ses igen den samme mekanisme 5, men her vist i lukket position.1 FIG. 3, a mechanism 5 similar to that shown in FIG. 3, but shown here in fully open position and in FIG. 4 again shows the same mechanism 5, but shown here in closed position.
I fig. 5 ses igen den samme mekanisme 5 i samme position som er vist i fig. 2, men denne gang vist isometrisk, så det let ses, at mekanismen 5 er opbygget som en ram-mekonstruktion, hvor praktisk talt alle elementer er i en højre og i en venstre udgave, hvorved en stabil og robust konstruktion opnås, hvor der ikke sker en skæv belastning af mekanismens elementer.In FIG. 5 again, the same mechanism 5 is seen in the same position as shown in FIG. 2, but this time shown isometrically, so that it is readily seen that mechanism 5 is constructed as a frame structure in which virtually all elements are in a right and in a left version, thus providing a stable and robust construction where no there is a skewed load of the mechanism elements.
