Mekanisme til anvendelse i stole.Mechanism for use in chairs.

Denne frembringelse består af en mekanisme, der ved anvendelse af en tværgående torsionsfjeder, kombineret med drejeled og glidepunkter - udvirker en variabel siddevinkel mellem ryg og sæde. Mekanismen arbejder ved et pres på torsionsfjederen ved hjælp af en kraft ført af personens ryg, samt ved personens egenvægtsbelastning i lodret plan på sædet, Mekanismen er udformet således at den ikke ændrer stolens rammehøjde .eller stabelhøjde væsentligt.This creation consists of a mechanism which, by using a transverse torsion spring, combined with pivot joints and sliding points - produces a variable seat angle between the back and seat. The mechanism works at a pressure on the torsion spring by means of a force carried by the person's back, as well as at the person's vertical weight load on the seat. The mechanism is designed so that it does not significantly alter the chair height or stack height.

Kendt teknik.Prior art.

Mekanismer til ændring af siddevinkler på stole er kendt fra kontorstole samt forskellige autostole I mange varianter, Disse mekanismer, som kan opdeles i synkron og fuldsynkron - mekanismer, er opbygget på flere sammensatte bærearme samt komplicerede fjeder og vægtsystemer. Disse mekanismer er ikke anvendelige til stabelstole, idet de forøger stabelhøjden væsentligt.Mechanisms for changing seat angles on chairs are known from office chairs as well as various car seats. In many variants, these mechanisms, which can be divided into synchronous and fully synchronous mechanisms, are built on several composite support arms as well as complicated springs and weight systems. These mechanisms are not applicable to stacking chairs as they significantly increase stacking height.

Det tekniske problem der skal løses.The technical problem to be solved.

De eksisterende mekanismer giver ikke mulighed for en lav byggehøjde, de eksisterende giver ikke mulighed for stabling, og giver ikke mulighed for at anvende den samme konstruktion til en række stolemodeller med identisk sæderamme. De kendte mekanismer er komplicerede og indeholder mange komponenter der vanskeliggør god integration i designprægede produkter.The existing mechanisms do not allow for a low building height, the existing ones do not allow for stacking, and do not allow the same construction to be used for a number of chair models with identical seat frame. The known mechanisms are complicated and contain many components that make it difficult to integrate well into design embossed products.

Den nye konstruktion bygger på, at sædet som placeres på en rammes 4 punkter: Forrest på to drejeled ,og bagest på glide/drejepunkter som er fastgjort på en bevægelige flange til fastgørelse af en stoleryg.The new construction is based on the seat being placed on the 4 points of a frame: the front of two swivel joints, and the rear of the sliding / turning points attached to a movable flange to secure a chair back.

Bagest på rammen er der et tværgående rør som er opdelt i 3 dele . To faste dele i hver side, samt et bevægeligt rør hvorpå flangen til ryggen er fastgjort. I fjederrøret er monteret en fjedermekanisme der består af een eller flere indsvejste fjedre mellem tre punkter. Funktionen opnås ved at personens vægt presser på de bageste glidepunkter samtidig med at personen rykker bagud og belaster stoleryggen i en bagudrettet vinkel. Fjeder mekanismen giver et behageligt modhold samtidig med at den tillader bevægelse bagud .Personens vægt er ved hjælp af trykpunkterne medvirkende til at bevæge ryggen bagud.At the back of the frame is a transverse tube which is divided into 3 parts. Two fixed parts on each side, as well as a movable tube on which the flange to the back is attached. In the spring tube is mounted a spring mechanism consisting of one or more welded springs between three points. The function is achieved by pushing the weight of the person to the rear sliding points while pushing the person backwards and loading the chair back at a backward angle. The spring mechanism provides comfortable restraint while allowing backward movement. The weight of the person contributes to the backward movement by means of the pressure points.

Der opnås en kompakt stærk og stabelhøjde-reducerende konstruktion, med brug af få materiale-resoursser, samt anvendelse af minimale dimensioner, der samtid muliggør at brugeren kan skifte fra arbejds - til lyttestilling underf.eks møder og konferencer.A compact strong and stack height-reducing design is achieved, with the use of few material resources, as well as the use of minimal dimensions, which at the same time allows the user to change from work - to listening position eg meetings and conferences.

Med frembringelsen gives mulighed for en meget komfortabel og enkel mekanisme tit brug i mange stoletyper.The creation allows for a very comfortable and simple mechanism for use in many chair types.

Den nye teknik.The new technique.

Den nye konstruktion sikrer, at sædet med to frontplacerede drejeled - forbundet med en lav horisontal ramme, - igen forbundet med det tværgående fjederrør - som via en flange er forbundet med stoiens ryg - at personen der sidder I mekanismen ved hjælp af sin vægt kan øge vinkelen mellem sæde og ryg .The new construction ensures that the seat with two front-mounted swivel joints - connected by a low horizontal frame - is again connected to the transverse spring tube - which is connected via a flange to the back of the chair - that the person sitting in the mechanism by means of his weight can increase the angle between seat and back.

Der opnås en kompakt stærk og stabelhøjde-reducerende konstruktion, med brug af få materiale resoursser, samt anvendelse af minimale dimensioner, der samtid muliggør at brugeren kan skifte fra arbejds- til lyttestilling under f.eks møder og konferencer.A compact strong and stack height-reducing design is achieved, with the use of few material resources, and the use of minimal dimensions, which at the same time allows the user to switch from working to listening position during, for example, meetings and conferences.

Med frembringelsen gives mulighed for en meget komfortabel og enkel mekanisme til brug i mange stoletyper.The creation allows for a very comfortable and simple mechanism for use in many chair types.

Det nye ved frembringelsen er at der ved en flad og pladsreducerende mekanisme kan opnås en mulighed for at skifte sidde - rygvinkel ved en let bevægelse, samtidig med at ryggen støtter brugeren I den forreste position. Det nye er at mekanismen kan anvendes til mange stoletyper, ligesom mekanismen giver mulighed for stabling af stole af søjletypen.What is new about the production is that by a flat and space-reducing mechanism, an opportunity to change the seat back angle can be achieved by a slight movement, while the back supports the user in the front position. What is new is that the mechanism can be used for many chair types, just as the mechanism allows for stacking of pillar type chairs.

Den Tekniske Virkning.The Technical Impact.

Ved at anvende den ovenfor nævnte teknik / konstruktion kan sæderammen udformes til flere stoletyper - siddevinkler, og anvendes til såvel flrebenede - cantilever - og søjlestolestel. Den nye teknik giver ligeledes mulighed for at tilpasse fjederens styrke ved at forlænge / forkorte de enkelte fjederelementer i forhold til stolens/stoleryggens størrelse og udformning .By using the above-mentioned technique / construction, the seat frame can be designed for several chair types - seating angles, and used for both multi-legged - cantilever - and pillar chairs. The new technique also offers the possibility to adjust the strength of the spring by extending / shortening the individual spring elements according to the size and shape of the chair / backrest.

Forrest på rammen er der på aksel-enderne monteret to drejelejer : D - D, som sikrer at sædet kan bevæge sig under ændring af vinkelen. Disse lejer kan integreres i sædekonstruktionen.At the front of the frame are two swivel bearings mounted on the shaft ends: D - D, which ensures that the seat can move while changing the angle. These bearings can be integrated into the seat construction.

Den faste ramme har to rørformede ender ved C-C hvor selve fjederelementets ender E - E fastgøres ved C - C .The fixed frame has two tubular ends at C-C where the ends E - E of the spring element itself are fixed at C - C.
