Denne opfindelse angår et lukkeorgan for tofløjede til samme side svingbare branddøre, omfattende en stående og en gående 5 dørfløj, hvor sidstnævnte dørfløj ved hjælp af et holdeorgan ved lukning kan fastholdes til den stående dørfløj, og hvor lukkeorganet kan monteres ved den stående dørfløjs forkant, og i brug ved lukning af den gående dørfløj fastlåser den stående dørfløj i dørhullet, idet den gående dørfløj ved lukningen er 10 indrettet til at påvirke et udløserorgan på lukkeorganet til vertikal forskydning af mindst een med udløserorganet koblet vertikalt forløbende rigle i den stående dørfløj, hvorved riglen går i indgreb med dørhullets beranding, og hvor riglen er fjederbelastet til at gå ud af indgreb med dørhullets beran-15 ding, når den gående dørfløj åbnes.This invention relates to a closure means for two-wing, pivotal fire doors which can be swiveled to the same side, comprising a standing and a walking door wing, wherein the latter door wing can be secured to the standing door wing by means of a closure and where the closing member can be mounted at the front of the standing door wing. and in use in closing the walking door wing, the standing door wing locks in the door hole, the walking door wing at the closure being arranged to actuate a release member on the closing member for vertical displacement of at least one vertically coupled bolt in the standing door where the latch engages with the doorhole taping, and the latch is spring-loaded to engage the doorhole latch when the pedestrian wing is opened.

I større bygninger monteres branddøre i passagerne mellem de enkelte bygningsafsnit. I tilfælde af brand i et bygningsafsnit lukkes branddørene automatisk for at hindre branden i at 20 brede sig til andre bygningsafsnit. Alt efter, hvor brede passagerne mellem bygningsafsnittene er, opsættes der enfløjede eller tofløjede sidehængte branddøre. Ved meget brede og høje passager anvendes også skydedøre eller -porte.In larger buildings, fire doors are installed in the passages between the individual building sections. In the event of a fire in a building section, the fire doors are automatically closed to prevent the fire from spreading to other building sections. Depending on the width of the passages between the building sections, single-wing or two-wing side-hung fire doors are installed. Sliding doors or gates are also used for very wide and high passages.

25 Af brandtekniske grunde kræver myndighederne ved tofløjede branddøre, at dørfløjene, når de er lukkede, ikke kun skal være fastlåst til hinanden, men også foroven og forneden i dørhullets beranding, dvs. i overkarmen (dørkarmens topstykke) og i gulvet, hhv. i dørkarmens bundstykke.25 For fire-technical reasons, the authorities of two-wing fire doors require that the door wings, when closed, must not only be locked to each other, but also at the top and bottom of the doorway's floor, ie. in the upper frame (door frame top) and in the floor, respectively. in the bottom frame of the door frame.

Et yderligere krav fra myndighedernes side er, at begge dørfløjenes fastlåsning i dørhullets beranding skal kunne ophæves ved betjening af eet greb, såsnart den gående dørfløj åbnes for personpassage. Den gående dørfløj er den dørfløj, der er 35 forsynet med dørgreb, og denne dørfløj skal normalt åbnes, før den anden dørfløj kan åbnes. Den anden dørfløj kaldes i det følgende den stående dørfløj, 2A further requirement on the part of the authorities is that the locking of both door wings in the doorhole's barrage must be able to be lifted by operating one handle as soon as the pedestrian wing is opened for passenger passage. The walking door wing is the door wing provided with a door handle, and this door wing usually has to be opened before the second door wing can be opened. The second door wing is hereinafter referred to as the standing door wing, 2

DK 163256 BDK 163256 B

Til den således beskrevne fastlåsning af dørfløjene foroven og forneden i dørhullets beranding anvender man normalt et lukkeorgan af den indledningsvist art, der ved tofløjede branddøre monteres ved den stående dørfløjs forkant (kanten modsat hæng-5 selkanten), hvilket lukkeorgan ved lukning af den gående dørfløj fastlåser den stående dørfløj i dørhullet, idet den gående dørfløj ved lukningen påvirker et udløserorgan på lukkeorganet til vertikal forskydning af mindst een med udløserorganet koblet vertikalt forløbende rigle i den stående dørfløj, 10 hvorved riglen går i indgreb med dørhullets beranding, og hvor riglen er fjederbelastet til at gå ud af indgreb med dørhullets beranding, når den gående dørfløj åbnes.For the thus-described locking of the door wings at the top and bottom of the door hole's striping, a closing member of the initial type is normally used, which is installed at two-wing fire doors at the leading edge of the standing door wing (the edge opposite the hinged edge), which closure means when closing the going door locking the standing door wing into the door hole, the passing door wing at the closing affecting a release member on the closing means for vertical displacement of at least one vertically extending bolt coupled with the trigger means, the lock engaging the door hole ring and the door hole touching, to disengage with the doorhole's flushing when the walking doorway is opened.

Der kendes forskellige konstruktioner af sådanne lukkeorganer, 15 som har det til fælles, at udløserorganet i brug stikker frem fra den stående dørfløjs smalside. Dette medfører, at der i bevægelsesmønstret ved de kendte konstruktioner af lukkeorganer, indgår en kilevirkning. Hermed menes en vinkelomsætning af en bevægelse ved lineær forskydning af to mekaniske dele 20 vinkelret på hinanden, hvor en flade eller en kant på en af delene glider hen ad en på den anden del udformet flade, der forløber i en spids vinkel til begge delenes forskydningsretninger. En sådan glidning er forbundet med slid af de i lukkeorganet indgående dele, så disse efter lang tids brug kan 25 frygtes ikke at være tilstrækkeligt brugsdygtige.Various constructions are known of such closing means, which have in common that the actuating means in use protrudes from the narrow side of the standing door wing. This means that a wedge effect is included in the pattern of movement of the known structures of closing members. By this is meant an angular conversion of a movement by linear displacement of two mechanical parts 20 perpendicular to each other, where a surface or edge of one of the parts slides along a surface formed on the other part which extends at an acute angle to the displacement directions of both parts. . Such a slip is associated with wear of the parts included in the closure member, so that after long use, these can be feared not to be sufficiently usable.

Det er opfindelsens formål at angive et lukkeorgan af den ovenfor angivne art, hvor der i de mekaniske deles bevægelsesmønster ikke indgår nogen kilevirkning, og hvor der derfor vil 30 være et langt mindre slid af delene i lukkeorganet.It is an object of the invention to provide a closure means of the above-mentioned type, in which the movement pattern of the mechanical parts does not include any wedge effect, and therefore there will be a much less wear of the parts in the closure means.

jj

Dette formål opnås ved et lukkeorgan af den omhandlede art, hvilket lukkeorgan ifølge opfindelsen er særegent ved , at udløserorganet er bestemt til anbringelse således, at det i brug 35 stikker frem fra den stående dørfløjs bredside og ved lukning af den gående dørfløj kan påvirkes af en i og for sig kendt slagliste, der er således anbragt på den gående dørfløj, at den overdækker sprækken mellem de lukkede dørfløje.This object is achieved by a closure member of the present invention, which closure member according to the invention is peculiar in that the trigger member is intended for positioning so that in use it protrudes from the width side of the standing door wing and upon closing the walking door wing can be influenced by a a percussion list known per se so arranged on the pedestrian wing that it covers the gap between the closed door wings.

Lukkeorganet ifølge opfindelsen adskiller sig herved fra de kendte konstruktioner, hvor udløserorganet omfatter en afskrå-et falle, som skydes ind i den stående dørfløj af den gående dørfløjs forkant ved en kilevirkning. Lukkeorganet ifølge op- 5 findelsen adskiller sig ligeledes fra de kendte konstruktioner, hvor udløserorganet er en drejefalle, det vil sige en falle, der af den gående dørfløjs forkant drejes omkring en lodret akse, hvorved en bag på fallen udformet skrueflade ved kilevirkning forskyder riglen.The closure means according to the invention hereby differs from the known constructions in which the triggering means comprises a sloping trap which is slid into the standing door wing of the front door of the walking door wing by a wedge action. The closure according to the invention also differs from the known constructions in which the release means is a pivot trap, that is, a pivot, which is rotated around the vertical axis by the front of the pedestrian wing, whereby a screw surface formed at the rear of the case displaces the bolt.

Ved lukkeorganet ifølge opfindelsen er det den gående dørfløjs slagliste, der støder an mod udløserorganet og dermed skyder det foran sig og ind mod den stående dørfløj, uden at der derved sker en relativ forskydning mellem slaglisten og udløser- 15 organet. Udløserorganets ind mod den stående dørfløj rettede bevægelse omsættes let til en forskydning af riglen af en eks-centermekanisme, hvilket heller ikke kræver nogen kilevirkning.By the closure device according to the invention, the impact strip of the walking door is abutting the trigger means and thus it shoots in front of it and towards the standing door wing, without there being a relative displacement between the impact strip and the trigger means. The movement of the trigger towards the standing door wing is readily translated into an offset by the eccentric mechanism, which also requires no wedge action.

20 Man opnår herved en lettere gang i lukkeorganet, idet den ved en kilevirkning fremkommende friktion mellem de involverede dele undgås. Denne lettere gang medvirker til at gøre lukkeorganets funktion sikrere.This provides an easier passage in the closing means, avoiding friction between the parts involved in a wedge action. This easier time helps to make the function of the closing device safer.

25 Ved en udførelsesform af opfindelsen er udløserorganet en i dens længderetning forskydelig tap, hvis ene ende ligger an mod en første flade på et i lukkeorganet svingeligt ophængt legeme, og hvis anden ende stikker frem fra den. stående dørfløj, og riglen er monteret forskydelig i dens længderetning 30 og fjederbelastet til anlæg mod en anden flade på legemet, i-det fladerne på legemet er således beliggende i forhold til legemets svingningsakse, at en forskydning af tappen ved legemets svingning omsættes til en forskydning af riglen på tværs af tappens bevægelsesretning.In one embodiment of the invention, the trigger means is a longitudinally displaceable pin, one end of which abuts a first face of a body pivotally suspended in the closure member and the other end protruding from it. standing door wing, and the bolt is slidably mounted in its longitudinal direction 30 and spring-loaded for abutment against another surface of the body, in that the surfaces of the body are positioned relative to the pivot axis of the body so that a displacement of the pin at the pivot of the body translates into a displacement. of the line across the direction of movement of the pin.

Denne udformning af ekscentermekanismen er enkel i sin opbygning, men andre udførelsesformer er også mulige. Udløserorganet kunne således være en del af det svingeligt ophængte lege- 35This design of the eccentric mechanism is simple in its construction, but other embodiments are also possible. Thus, the trigger member could be part of the pivotally suspended toy 35

Lukkeorganet kan med fordel indbygges i et hylster, hvorved mekanismen beskyttes mod ydre påvirkninger og man får en mon-5 teringsvenlig, lethåndterbar enhed, der kan anbringes i en forholdsvis lille not eller udtagning ved den stående dørfløjs forkant.Advantageously, the closure member can be built into a casing, thereby protecting the mechanism from external influences and providing a mounting-friendly, easy-to-handle unit which can be placed in a relatively small groove or recess at the front of the standing door wing.

Lukkeorganet ifølge opfindelsen skal i det følgende forklares 10 nærmere under henvisning til det på den medfølgende tegning viste foretrukne udførelseseksempel, hvor:The closure means according to the invention will be explained in more detail below with reference to the preferred embodiment shown in the accompanying drawing, in which:

Fig. 1 og 2 viser et lukkeorgan ifølge opfindelsen henholdsvis i tværsnit og set fra siden, og 15 fig. 3 viser fra oven monteringen af et lukkeorgan ifølge opfindelsen i en tofløjet branddør.FIG. 1 and 2 are a side cross-sectional and side view, respectively, and FIG. 3 shows from above the mounting of a closure according to the invention in a two-wing fire door.

Ved lukkeorganet ifølge fig. 1 er selve mekanismen indbygget i 20 et hylster 1 med rektangulært tværsnit, for eksempel et stykke firkantrør. Et trekantet legeme 2 er svingeligt ophængt i en i brug horisontalt forløbende aksel 3, der er ført gennem hylsterets 1 væg. Legemet 2 svinges omkring akslen 3 ved forskydning i længderetningen af et udløserorgan 4 i form af en 25 cylindrisk tap. Den cylindriske tap 4 udgøres af et rørstykke, der med en skrue (ikke vist) skrues fast på en føringsplade 5, som kan glide hen og tilbage langs en føringsstang 6 i hylsteret 1.At the closure member of FIG. 1, the mechanism itself is built into a casing 1 of rectangular cross section, for example a piece of square tube. A triangular body 2 is pivotally suspended in a horizontally extending shaft 3 which is passed through the wall of the sheath 1. The body 2 is pivoted about the shaft 3 by longitudinal displacement of a release member 4 in the form of a cylindrical pin. The cylindrical pin 4 consists of a pipe piece that is screwed onto a guide plate 5 which can slide back and forth along a guide rod 6 in the housing 1 with a screw (not shown).

30 Som det fremgår af fig. 2 anbringes udløserorganet asymmetrisk, enten nærmere den ene eller den anden side af hylstret 1, hvorved lukkeorganet kan anvendes både foroven og forneden på en dørfløj og dermed også for venstrehængte og for højrehængte dørfløje.30 As can be seen from FIG. 2, the release means is placed asymmetrically, either closer to one or the other side of the casing 1, whereby the closing means can be used both at the top and bottom of a door wing and thus also for left-hung and right-hung door wings.

Når udløserorganet 4 trykkes ind i hylsteret 1, svinges legemet 2 til den med stiplet linje viste position, idet føringspladen 5 ligger an mod den ene smalside af legemet 2. Herved 35When the release member 4 is pressed into the sleeve 1, the body 2 is pivoted to the dotted line position, the guide plate 5 abutting one narrow side of the body 2. Hereby 35

DK 163256 BDK 163256 B

5 svinges legemets anden smalside 8 opefter. På denne anden smalside 8 af legemet hviler en forskydelig ramme 9, som af en trykfjeder 10 er belastet til anlæg mod legemet 2. Denne ramme 9 forskydes ved legemets svingning opefter mod virkningen af 5 fjederen 10.5, the second narrow side 8 of the body is pivoted upwards. On this second narrow side 8 of the body rests a displaceable frame 9, which is loaded by a compression spring 10 for abutment against the body 2. This frame 9 is displaced by the oscillation of the body upwards against the action of the spring 10.

Rammen 9 bærer en rigle 11, der er ført gennem en føringsplade 12, som er indsvejst på tværs i enden af hylsteret 1. Riglen 11 er en cylindrisk stift, der er ført gennem føringspladen 10 12, som danner den øvre væg af rammen 9. Tværs igennem den del af riglen 11, der sidder indeni rammen 9, er ført to stifter 13 og 13A, der tjener som anslag for en på riglens ende mellem stifterne påsat skive 14. En trykfjeder 15 er sat i spænd mellem denne skive 14 og den anden væg 16 af rammen. Trykfjederen 15 15 holder således riglen 11 i spænd opefter i rammen 9.The frame 9 carries a groove 11 which is passed through a guide plate 12 which is welded transversely at the end of the casing 1. The bolt 11 is a cylindrical pin passed through the guide plate 10 12 which forms the upper wall of the frame 9. Across the portion of the groove 11 which sits within the frame 9 are passed two pins 13 and 13A, which act as a stop for a disc 14 mounted on the end of the bolt between the pins 14. second wall 16 of the frame. The compression spring 15 15 thus holds the bolt 11 in tension upwards in the frame 9.

Såfremt riglen 11 blokeres af en ydre forhindring og ikke kan skydes ud af hylsteret 1, når rammen 9 skydes opad af legemet 2, vil fjederen 15 give efter for det derved opstående tryk.If the latch 11 is blocked by an outer obstruction and cannot be pushed out of the sheath 1 as the frame 9 is pushed upwardly by the body 2, the spring 15 will give way to the resulting pressure.

20 Denne indspænding af riglen 11 i rammen 9 gør, at det altid er muligt at trykke udløserorganet 4 ind i hylsteret 1, uanset om riglen 11 er fri eller blokeret.This clamping of the latch 11 in the frame 9 makes it always possible to push the release member 4 into the casing 1, regardless of whether the latch 11 is free or blocked.

Når udløserorganet 4 ikke holdes inde i hylsteret 1 af en ydre 25 kraft, vil fjederen 10 presse rammen 9 og riglen 11 nedad, hvorved legemet 2 svinges tilbage til den fuldt optrukne position og udløserorganet 4 skydes ud fra hylsteret 1.When the release member 4 is not held inside the sheath 1 by an external force, the spring 10 will push the frame 9 and the shaft 11 downwardly, thereby turning the body 2 back into the fully extended position and releasing the release member 4 from the sheath 1.

Fig. 3 viser skematisk i et syn fra oven lukkeorganets monte-30 ring ved forkanten af den stående dørfløj 20 i en sidehængt branddør med to dørfløje 20, 21. Dørfløjene ved sådanne branddøre er forsynet med hver sin slagliste 22, 23, som har til formål at overdække sprækken mellem dørfløjene, når de er lukket.FIG. 3 shows schematically in a view from above the mounting member assembly 30 at the leading edge of the standing door wing 20 in a side-hung fire door with two door wings 20, 21. The door wings of such fire doors are each provided with a punching strip 22, 23, which is intended to: cover the gap between the door wings when closed.

Lukkeorganet 100 monteres i en ikke nærmere vist not eller udtagning ved forkanten af den stående dørfløj 20 og på en sådan måde, at udløserorganet 4 stikker frem fra den" stående dør- 35 6The closing member 100 is mounted in a groove or recess not shown at the front of the standing door wing 20 and in such a way that the release member 4 protrudes from the "standing door 6".

Dette er ikke nærmere 5 vist på tegningen.wing width 25 within the area covered by the passing door wing impact strip 23. The latch 11 points upwards and will in use sit opposite a hole in a final look or the like at the top of the door frame carrying the door wings. This is not detailed in the drawing.

Når den gående dørfløj 21 lukkes af den dørpumpe, der skal være monteret ved en branddør, trykkes udløserorganet 4 ind i lukkeorganet 100 af slaglisten 23. Herved forskydes riglen 11 10 opefter i lukkeorganet 100 og går i indgreb med slutblikket i dørkarmen.When the passing door wing 21 is closed by the door pump to be mounted by a fire door, the trigger means 4 is pushed into the closing member 100 of the punching list 23. Hereby the lock 11 10 is displaced upwardly in the closing member 100 and engages with the final look in the door frame.

Ved tilsvarende montering af et lukkeorgan forneden i den stående dørfløj 20 opnår man, at denne fastlåses i dørhullets be-15 randing både foroven og forneden, når den gående dørfløj lukkes til.By correspondingly mounting a closure member at the bottom of the standing door wing 20, it is achieved that it is locked in the door hole's rim both at the top and the bottom when the walking door wing is closed.

Når den gående dørfløj 21 åbnes, frigives udløserorganet 4 af slaglisten 23, hvorefter fjederen 10 vil presse riglen 11 og 20 udløserorganet 4 tilbage til deres udgangsposition. Herved ophæves dørfløjenes fastlåsning i dørhullets beranding automatisk.When the going door 21 is opened, the release member 4 is released by the impact strip 23, after which the spring 10 will push the latch 11 and 20 the release member 4 back to their initial position. This will automatically unlock the door flaps in the doorhole striping.
