Description
Oppfinnelsen vedrører en røk- og varmeavtrekksinnretning for tak, bestående av en til takbekledningen fastgjort ramme, som omgir takåpningen og er dannet av side- og endevegger og svingbart opplagrede tildekningssdeler, som tildekker rammen, og hvis omdreiningspunkter ligger i endeveggene innenfor tyngdepunktsaksen for de tilhørende tildekningsdeler, idet disse deler i lukket tilstand er forbundet med en lås og fiksert i deres endestilling. The invention relates to a smoke and heat extraction device for roofs, consisting of a frame attached to the roof covering, which surrounds the roof opening and is formed by side and end walls and pivotably supported covering parts, which cover the frame, and whose pivot points lie in the end walls within the center of gravity axis of the associated covering parts , these parts in the closed state being connected by a lock and fixed in their final position.
Til slike innretninger stilles det forskjellige There are different requirements for such devices
krav. Således er det nødvendig at hele tverrsnittet for takåpningen skal frigis og at avtrekket også virker når vind strømmer loddrett til avtrekksplanet. claim. Thus, it is necessary that the entire cross-section for the roof opening must be freed and that the exhaust also works when wind flows vertically to the exhaust plane.
Fra beskrivelsen i U.S. patent nr. 3741101 er det kjent en røk- og varmeavtrekksinnretning av den angitte type, hvilken innretning åpnes automatisk i tilfelle av behov og fri-gir det fulle tverrsnitt for utstrømning av røk uavhengig av til-strømningsretningen for ytterluften. Ved den kjente innretning er takåpningen omgitt av en av vegger dannet ramme ag tildekket av minst to tildekningsdeler. Disse tildekningsdeler er drei-bare og forbundet med hverandre i lukket stilling ved hjelp av en låsemekanisme og fiksert i en endestilling. From the description in the U.S. patent no. 3741101, a smoke and heat extraction device of the specified type is known, which device opens automatically in case of need and releases the full cross-section for the outflow of smoke regardless of the direction of inflow of the outside air. In the known device, the roof opening is surrounded by a frame formed by walls and covered by at least two covering parts. These cover parts are rotatable and connected to each other in the closed position by means of a locking mechanism and fixed in an end position.
Denne kjente innretning har den ulempe at tildekningsdelene ved en ubremset åpning slår mot de tilhørende vegger, slik at det kreves kraftigere vegger for å unngå deformasjoner, som kunne føre til en fastklemming av avtrekkets deler. En ytterligere ulempe er at tildekningsdelene, hvis vekt ikke er liten, i hvert fall ved lukking må beveges manuelt, uten at.det kan benyttes mekaniske hjelpemidler. Det kreves til dette så meget kraft at en person alene ikke bestandig vil kunne lukke avtrekket. This known device has the disadvantage that the covering parts strike against the associated walls when an unbraked opening is made, so that stronger walls are required to avoid deformations, which could lead to a jamming of the extractor's parts. A further disadvantage is that the covering parts, whose weight is not small, at least when closing must be moved manually, without the use of mechanical aids. This requires so much force that one person alone will not always be able to close the extractor.
Foreliggende oppfinnelse har til hensikt å tilveie-bringe en innretning av den innledningsvis nevnte, type, ved hvilken de ovenfor nevnte ulemper er unngått, og dette oppnås ifølge oppfinnelsen ved at innretningen er utformet som angitt i patentkravet. The purpose of the present invention is to provide a device of the type mentioned at the outset, in which the above-mentioned disadvantages are avoided, and this is achieved according to the invention by the device being designed as stated in the patent claim.
Ved denne utforming oppnår man at fjærene ved åpning av låsen først trekker tildekningsdelene til endestilling, men at de etter ombøyning av fjærene avbremser åpningen og derved forhindrer at tildekningsdelene slår mot tilhørende veggdeler. With this design, it is achieved that when the lock is opened, the springs first pull the cover parts to the end position, but that after bending the springs, they slow down the opening and thereby prevent the cover parts from striking the associated wall parts.
Samtidig virker fjærene under lukning til understøtt-else av lukkingen, slik at innretningen kan lukkes med betyde-lig mindre anvendelse av kraft enn de tidligere kjente innretninger av denne type. Påvirkningen av låsingen kan enten skje over et stangsystem eller ved hjelp av en pneumatisk élier elekt-risk mekanisme. At the same time, the springs act during closing to support the closing, so that the device can be closed with significantly less application of force than the previously known devices of this type. The influence of the locking can either take place via a rod system or by means of a pneumatic or electric mechanism.
Oppfinnelsen skal i det følgende nærmere forklares ved hjelp av utf ørelseseksempler som er fremstilt på tegningen, som viser: fig. 1 et riss av en innretning ifølge oppfinnelsen i åpen tilstand, 'In the following, the invention will be explained in more detail with the help of examples of implementation which are shown in the drawing, which shows: fig. 1 a drawing of a device according to the invention in the open state,
fig. 2 et riss av innretningen ifølge oppfinnelsen fig. 2 a diagram of the device according to the invention
i lukket tilstand. in the closed state.
På fig. 1 og 2 er det vist en innretning ifølge oppfinnelsen for tildekning, henholdsvis frigivning av takåpningen 11. På en påsettingsflens 10 er det festet vegger 4, 5, 12 og In fig. 1 and 2, a device according to the invention is shown for covering, respectively releasing the roof opening 11. On an attachment flange 10, walls 4, 5, 12 and
13 som begrenser åpningen 11. Tildekningsdelene 1 og 2 med sidedelene 8, 9 er dreibart opplagret ved hjelp av opplagringene 3a, 3b, slik at de kan tildekke åpningen 11. Denne opplagring 3a, 3b består av en i veggen 4, henholdsvis 5 lagret fast tapp og en på sidedelen 8, henholdsvis 9 festet lask med en lager-bøssing som tappen rager inn i. Tappen er slik opplagret på veggdelen 4, henholdsvis 5 at dreiepunktet for tildekningsdelene 1, henholdsvis 2 ligger innenfor det plan i hvilket tildeknings-innretningens tyngdepunkt ligger. Dermed blir det oppnådd at ved åpning av låsen 6, åpningen skjer ved tilbakeklapping av tildekningsdelene uavhengig av fjærene 7. I åpningsendestilling ligger tildekningsdelen 1, henholdsvis 2 omtrent parallelt med veggene 12 og 13 og danner, da de rager opp over den øvre kant 14 til veggene, en ekstra vindledeflate. Fjærene 7 er slik anordnet at de ved begynnelsen av åpningsprosessen akselererer denne ved hjelp av fjærkraften, og etter omleggingen bremser ned bevegelsen på den videre vei for tildekningsdelene mot åp-ningsendestillingen. Dermed blir det oppnådd at til tross for hurtig åpning, tildekningsdelene ikke med full kraft støter mot veggene. I sidedelene 8, henholdvis 9 er det anordnet vinkel-formede lasker 15, som i lukket tilstand ligger an mot laskene 18 og dermed forhindrer at tildekningsdelene kan riste og dermed støye. Til slutt er det på smalveggene anordnet påsetnings-plater 16, 17 som i åpen tilstand bidrar til en økning av vind-ledeflåtene. De har dessuten den fordel at de beskytter fjærene 7 og deres opphengning. 13 which limits the opening 11. The covering parts 1 and 2 with the side parts 8, 9 are rotatably supported by means of the supports 3a, 3b, so that they can cover the opening 11. This support 3a, 3b consists of one in the wall 4, respectively 5 stored firmly pin and a latch attached to the side part 8, respectively 9 with a bearing bushing into which the pin protrudes. The pin is so supported on the wall part 4, respectively 5 that the pivot point for the covering parts 1, respectively 2 lies within the plane in which the center of gravity of the covering device is located. In this way, it is achieved that when opening the lock 6, the opening occurs by folding back the cover parts independently of the springs 7. In the opening end position, the cover part 1, respectively 2 lies approximately parallel to the walls 12 and 13 and forms, as they protrude above the upper edge 14 to the walls, an additional wind guide surface. The springs 7 are arranged in such a way that at the beginning of the opening process they accelerate this with the help of the spring force, and after the reversal slows down the movement on the further path of the covering parts towards the opening end position. In this way, it is achieved that despite rapid opening, the covering parts do not hit the walls with full force. In the side parts 8, respectively 9, there are arranged angular flaps 15, which in the closed state rest against the flaps 18 and thus prevent the cover parts from shaking and thus making noise. Finally, attachment plates 16, 17 are arranged on the narrow walls which, in the open state, contribute to an increase in the wind deflectors. They also have the advantage that they protect the springs 7 and their suspension.
Den pneumatiske betjening som er foretrukket fremfor stenger samt de sikkerhetselementer som bevirker en hurtig åp-ningsprosess i avhengighet av temperatur eller røktetthet er ikke vist på tegningen. Disse byggedeler er kjent og muliggjør at innretningen ifølge oppfinnelsen kan benyttes såvel til luft-ing som også i branntilfelle som brannmelde- og sikkerhetsinn-retning. The pneumatic operation which is preferred over rods as well as the safety elements which effect a rapid opening process depending on temperature or smoke density are not shown in the drawing. These components are known and enable the device according to the invention to be used both for ventilation and also in the event of a fire as a fire alarm and safety device.
