På ritningarna betecknas med hänvisningssiffran 1 ett dörrblad och företrädesvis då ett sådant dörrblad som lämpar sig att användas som en branddörr. Sagda dörrblad l uppbäres me- delst vid dess ena sidokant resp. en dörrkarmdel 2 anordnade gångleder 3, av i och för sig känt slag. Dörrbladets l andra motstående sidokant uppbär lämpligen låsorgan 4, som är anpassat att samverka med en på avstånd från den första dörrkarmdelen belägen andra dörrkarmdel 5. Dörrbladet, l som företrädesvis är tillverkat av metallmaterial, exempelvis stålplåt, Dobelplàt, aluzinkplåt etc., är i föreliggande exempel bildat av två varandra i huvudsak identiskt lika sidohalvor 1A resp. 1B, vilka sammankopplas med varandra så att de bildar ett dörrblad 1 som är ihåligt. På ritningarna visas i fig. 2 en sådan sidohalva lB i färdigformat skick och som kan vara framställd av ett metall- ämne ll som i utbrett skick uppvisar den i fig. 5 visade formen, och vilket ämne ll är avsett att bockas utmed de streckade linjerna till den i fig. 2 visade färdigvikta formen.In the drawings, the reference numeral 1 denotes a door leaf and preferably such a door leaf which is suitable for use as a fire door. Said door leaf l is supported by means at one of its side edges resp. a door frame part 2 arranged hinges 3, of a kind known per se. The second opposite side edge of the door leaf 1 suitably carries locking means 4, which are adapted to co-operate with a second door frame part 5 located at a distance from the first door frame part. examples formed by two substantially identical side halves 1A resp. 1B, which are interconnected so as to form a door leaf 1 which is hollow. The drawings show in Fig. 2 such a side half 1B in finished form and which may be made of a metal blank 11 which in widespread condition has the shape shown in Fig. 5, and which blank 11 is intended to be bent along the dashed lines. to the pre-folded mold shown in Fig. 2.

Kopplingsorgan 6, 7 i form av omgripande resp. omgripbara 7 företrädesvis snäppliknande sådana organ, som lämpligen är rännformiga resp. som sträcker sig utmed i huvudsak hela dörrbladets l vertikala utsträckning, när dörrbladet 1 uppbäres vid en karm 2, 5, är anordnade vid exempelvis ytter- änden av en från dörrbladsplanskivan 1A resp. lB vinkelställd gavel 8 resp. vid en kant 9 av sagda skiva 1A resp. lB såsom framgår av fig. 2. Sagda kopplingsorgan 6, 7 framställes liksom gaveln 8 företrädesvis samtidigt genom rullformning medan två ytterligare gavlar 10 resp. 11, som vid dörrbladets 1 verksamma läge sträcker sig horisontellt och som är belägna angränsande till sagda vertikala gavel 8, lämpligen vikes var för sig. I en speciell maskin kan exempelvis nithål 12 med försänkning 13 utföras vid sagda horisontella gavlar 10, ll på lämpligt in- bördes avstånd så att de kommer mitt för komplementära nithål 12 etc. på en sammankopplingsbar dörrbladsplansida 1A resp. lB.Coupling means 6, 7 in the form of gripping resp. grippable 7, preferably snap-like means, which are suitably gutter-shaped resp. which extend along substantially the entire vertical extent of the door leaf 1, when the door leaf 1 is supported at a frame 2, 5, are arranged at, for example, the outer end of one from the door leaf plane disc 1A resp. 1B angled end wall 8 resp. at an edge 9 of said disc 1A resp. 1B as can be seen from Fig. 2. Said coupling means 6, 7 are manufactured, like the end wall 8, preferably simultaneously by roll forming, while two further ends 10 resp. 11, which at the operative position of the door leaf 1 extends horizontally and which are located adjacent to said vertical end wall 8, are preferably folded separately. In a special machine, for example, rivet holes 12 with recess 13 can be made at said horizontal ends 10, 11 at a suitable mutual distance so that they come opposite complementary rivet holes 12 etc. on an interconnectable door leaf flat side 1A resp. lB.

De båda med varandra sammankopplingsbara kopp- lingsorganen 6, 7, som är anordnade på var sin dörrbladsplansida IA, 1B, vars tvärsnittsform'framgår av fig. 7 och 8 på ritningarna, -._._._.__...-..__._.......___:... . _.._____ ___ g 3 8103482-9 är anordnade att genom materialets fjädrande egenskaper i dörr- bladsplansidorna 1A resp. lB kunna fjädra ut resp. tryckas ihop när de sammanföres med varandra i pilarnas riktning. En vinkel- ställd tunga 61 förhindrar vid kopplingsorganens 6, 7 kopplade skick det komplementära omgripna kopplingsorganet 7 att föras ut ur den ränna 611 som det omgripande kopplingsorganet 6 bildar genom att det samverkar med en fjädrande tunga 71 vid sagda komplementära kopplingsorgan 7.The two interconnecting coupling members 6, 7, which are arranged on each door leaf plan side 1A, 1B, the cross-sectional shape of which can be seen in Figs. 7 and 8 in the drawings, -._._._.__. .__._.......___: .... _.._____ ___ g 3 8103482-9 are arranged that by the resilient properties of the material in the door leaf plan sides 1A resp. lB be able to spring out resp. are compressed when brought together in the direction of the arrows. An angular tongue 61 prevents, at the coupled condition of the coupling means 6, 7, the complementary gripped coupling member 7 from being removed from the groove 611 formed by the circumferential coupling member 6 by cooperating with a resilient tongue 71 at said complementary coupling means 7.

Montering av tvâ dörrbladshalvor 1A, lB till va- randra sker genom att de placeras med sina resp. plansidor mitt för varandra sà att gavlarna 8, 10, 11 på resp. skiva 1A resp. lB är riktade mot varandra. Gavlarna 10, 11 vid den ena skivan 1A anordnas intill motsvarande gavlar 10, 11 på den andra skivan 1B såsom visas i fig. 4 varefter de båda skivorna 1A resp. lB föres i riktning mot varandra såsom visas i fig. 7 och 8. Fäst- organen 6, 7 pà resp. skiva 1A, 1B kommer därvid i ingrepp med varandra så att det ena organet 7 omgripes av det andra organet 6 vid resp. dörrblads 1A, 1B vertikala gavel 8 och sida 9. Där- efter fästes de horisontella gavlarna 10, 11 samman med varandra medelst exempelvis blindnit 14 som införes från utsidan av gaveln 10, ll genom öppningarna 12 och nitas därefter fast så att gavlarna 10, ll fastpressas mot varandra. Eventuellt kan tomrummet mellan de båda skivorna 1A, 1B fyllas med något lämpligt material om detta är önskvärt, exempelvis isolering etc. Även andra fästorgan än de ovan beskrivna och på ritningarna visade kan naturligtvis tillämpas vid en anordning av ovan angivet slag.Assembly of two door leaf halves 1A, 1B to each other takes place by placing them with their resp. plan sides in the middle of each other so that the ends 8, 10, 11 on resp. disc 1A resp. lB are directed towards each other. The ends 10, 11 at one disc 1A are arranged next to corresponding ends 10, 11 of the other disc 1B as shown in Fig. 4, after which the two discs 1A resp. 1B is moved in the direction of each other as shown in Figs. 7 and 8. The fastening members 6, 7 on resp. disc 1A, 1B then engage with each other so that one member 7 is gripped by the other member 6 at resp. door leaves 1A, 1B vertical end 8 and side 9. Then the horizontal ends 10, 11 are fastened together by means of, for example, blind rivets 14 which are inserted from the outside of the end 10, 11 through the openings 12 and then riveted so that the ends 10, 11 pressed against each other. Optionally, the void between the two sheets 1A, 1B can be filled with any suitable material if this is desired, for example insulation, etc. Fastening means other than those described above and shown in the drawings can of course be applied to a device of the type indicated above.

Uppfinningen är ej begränsad till det på rit~ ningarna visade och ovan beskrivna utföringsexemplet utan kan varieras inom ramen för efterföljande patentkrav. Det är även möjligt att tillverka skivorna på ett och samma dörrblad av olika material samt att anordna fler än två stycken skivor till att bilda ett dörrblad. *a-Pcgg gazxinfïThe invention is not limited to the exemplary embodiment shown in the drawings and described above, but can be varied within the scope of the appended claims. It is also possible to manufacture the panels on one and the same door leaf from different materials and to arrange more than two panels to form a door leaf. * a-Pcgg gazxinfï
