Description

Oppfinnelsen vedrører en stol, hvor et sete med to setesider innbefatter et platelegeme som er forbundet med et understell. The invention relates to a chair, where a seat with two seat sides includes a plate body which is connected to a frame.

Oppfinnelsen tar utgangspunkt i den kjente stoltype hvor stolens sete og rygg dannes av fortrinnsvis laminerte, i tre tilformede eller i plast støpt platelegeme, som bæres av et fortrinnsvis av fire ben dannet understell, men er ikke begrenset til en slik spesifikk stoltype. The invention is based on the known chair type where the seat and back of the chair are formed by preferably laminated, shaped in wood or molded in plastic plate body, which is supported by a frame preferably formed by four legs, but is not limited to such a specific type of chair.

Fra US 4,529,247 er det kjent en stol som har en setedel i form av et platelegeme som er forbundet med et understell via en vippemekanisme. Den del av platelegemet som ligger mellom forbindelsen med understellet og resten av platelegemet er utformet som et torsjonslegeme. Tilsvarende er en del av platelegemet i stolryggen mellom et parti som danner forlengelsen av platelegemets setedel og resten av platelegemet i ryggpartiet utformet som et torsjonslegeme. Stolens vippebevegelse ved bruk ivaretas hovedsakelig av vippemekanismen, men torsjonslegemet bidrar også til å gi en fleksibel sittestilling. From US 4,529,247 a chair is known which has a seat part in the form of a plate body which is connected to a base via a tilting mechanism. The part of the plate body that lies between the connection with the undercarriage and the rest of the plate body is designed as a torsion body. Correspondingly, part of the plate body in the back of the chair between a part which forms the extension of the seat part of the plate body and the rest of the plate body in the back part is designed as a torsion body. The tilting movement of the chair during use is mainly handled by the tilting mechanism, but the torsion body also helps to provide a flexible sitting position.

Stoler av denne type er enkle, men byr allikevel på en relativ god sittekomfort, med mulighet for en viss svikt i ryggen. Chairs of this type are simple, but still offer relatively good sitting comfort, with the possibility of some back pain.

Det foreligger imidlertid et behov for bedring av sittekomforten, med mulighet for en vippebevegelse for stolkroppen forover og bakover fra normalstillingen Således er det et ønske å kunne lene seg forover med støttende nedtrykking av stolsetets fremre parti eller lene seg noe bakover mot ryggstøtten, altså slik at stolsetet vipper bakoverom en tverrgående akse. However, there is a need to improve sitting comfort, with the possibility of a tilting movement for the chair body forwards and backwards from the normal position. Thus, there is a desire to be able to lean forward with supportive pressure from the front part of the chair seat or to lean slightly backwards against the backrest, i.e. so that the chair seat tilts backwards about a transverse axis.

Det er en hensikt med oppfinnelsen å tilveiebringe en stol med et fleksibelt/spenstig platelegeme som muliggjør at selve platelegemet eller stolsete har materialsvikt som muliggjør vippebevegelser på en enkel måte, uten bruk av tilleggsmidler så som dreieakser, lagre, kompresjonslegemer, fjærer, torsjonsstenger og lignende, slik det er kjent fra dyrere stoler, så som avanserte kontorstoler og andre sittemøbler. Ifølge oppfinnelsen foreslås det derfor en stol som angitt i krav 1. Ytterligere trekk ved stolen er angitt i det uselvstendige krav. It is a purpose of the invention to provide a chair with a flexible/resilient plate body which enables the plate body itself or chair seat to have material failure which enables tilting movements in a simple way, without the use of additional means such as pivot axes, bearings, compression bodies, springs, torsion bars and the like , as it is known from more expensive chairs, such as advanced office chairs and other seating furniture. According to the invention, a chair as stated in claim 1 is therefore proposed. Further features of the chair are stated in the independent claim.

Ifølge oppfinnelsen foreslås det å utnytte selve platelegemet som torsjonslegeme, nærmere bestemt ved at en del av platelegemet mellom forbindelsen med understellet og resten av platelegemet, er utformet som et torsjonslegeme. According to the invention, it is proposed to use the plate body itself as a torsion body, more specifically in that a part of the plate body between the connection with the undercarriage and the rest of the plate body is designed as a torsion body.

På en frapperende enkel måte oppnås derved en stol hvor brukeren kan utføre gunstige og ønskede vippebevegelser forover og bakover , fra en bakoverlenet hvilestilling til en forovervinklet sittestilling, hele tiden med full understøttelse, på samme måte som i mer avanserte stoler med vippemekanismer. I en stol hvor platelegemet er forbundet med understellet ved hver av de to setesider, kan torsjonslegemet fordelaktig være slik utformet at det i platelegemet fra hver side er utformet et fra setesiden innoverrettet, svekket parti på hver side av forbindelsen med understellet. In a startlingly simple way, a chair is thereby achieved where the user can carry out favorable and desired tilting movements forwards and backwards, from a reclined resting position to a forward-angled sitting position, all the time with full support, in the same way as in more advanced chairs with tilting mechanisms. In a chair where the plate body is connected to the chassis at each of the two seat sides, the torsion body can advantageously be designed in such a way that a weakened part is formed in the plate body from each side, directed inwards from the seat side, on each side of the connection with the chassis.

I en slik stol kan torsjonslegemet fordelaktig være utformet ved at det i platelegemet er uttatt et innsnitt fra hver seteside, på hver side av forbindelsen med understellet. In such a chair, the torsion body can advantageously be designed in that an incision is made in the plate body from each side of the seat, on each side of the connection with the chassis.

I en stol hvor platelegemet er forbundet sentralt mellom setesidene med understellet, er torsjonslegemet fordelaktig utformet ved at det i platelegemet er utformet et svekket parti henholdsvis er uttatt et tverrgående begrenset innsnitt på hver side av forbindelsen med understellet. In a chair where the plate body is connected centrally between the seat sides to the chassis, the torsion body is advantageously designed in that a weakened part is formed in the plate body or a transverse limited incision is made on each side of the connection with the chassis.

I en fordelaktig utførelsésform strekker platelegemet seg enhetlig i setet og en stolrygg. In an advantageous embodiment, the plate body extends uniformly in the seat and a chair back.

Fordelaktig kan det i en slik stolrygg være utformet et torsjonslegeme, idet platelegemet har svekninger eller innsnitt i ryggpartiet som nevnt for setet, fortrinnsvis omtrent midt i stolrygghøyden. Slike svekninger/ innsnitt vil gi en fleksibilitet med en vridningsmulighet for platelegemet. Dette muliggjør fleksibilitet i en ellers velformet ryggstøtte, men muliggjør også at ryggplaten kan være plan i utgangspunktet, og føye seg etter brukerens rygg ved belastning. Advantageously, a torsion body can be designed in such a chair back, as the plate body has weaknesses or incisions in the back part as mentioned for the seat, preferably approximately in the middle of the chair back height. Such weakenings/incisions will provide flexibility with a possibility of twisting for the plate body. This enables flexibility in an otherwise well-shaped back support, but also enables the back plate to be flat initially, and to conform to the user's back under load.

Oppfinnelsen skal nå forklares nærmere, under henvisning til tegningen, hvor The invention will now be explained in more detail, with reference to the drawing, where

Figur 1 viser et perspektivriss av en stol ifølge oppfinnelsen, Figure 1 shows a perspective view of a chair according to the invention,

Figur 2 viser et perspektiv riss av en annen stol ifølge oppfinnelsen, Figure 2 shows a perspective view of another chair according to the invention,

Figur 3 viser et perspektivriss av nok en stol ifølge oppfinnelsen og Figure 3 shows a perspective view of yet another chair according to the invention and

Figur 4a, b og c viser skjematiske sideriss av en stol som i figur 1, med angivelse av vippebevegelser. Figure 4a, b and c show schematic side views of a chair as in Figure 1, with an indication of rocking movements.

Figur 5a-d viser en illustrasjon svarende til figur 4a-c, men av en annen utførelse. Figure 5a-d shows an illustration similar to Figure 4a-c, but of a different design.

I figur 1 er det vist en stol 1 oppbygget av et laminert platelegeme 2 som ved de to setesidene 3 og 4 er forbundet 5 og 6 med et understell som her består av to fra setet 7 innbyrdes vinkelstilte ben 8 og 9. Figure 1 shows a chair 1 made up of a laminated plate body 2 which, at the two seat sides 3 and 4, is connected 5 and 6 with a base which here consists of two legs 8 and 9 set at an angle from the seat 7 to each other.

I platelegemet 2 er det på hver side av forbindelsene 5,6 tatt ut et innsnitt 10, 11, 12 og 13, derved dannes det et torsjonslegeme 14 av den mellomliggende del av platelegemet 2. Den i figur 2 viste stol er som i figur 1, men stolryggen er utformet med innsnitt 15-19 slik at platelegemet 2 blir fleksibelt og vridbart i dette ryggområde. In the plate body 2, on each side of the connections 5,6, an incision 10, 11, 12 and 13 has been taken out, thereby forming a torsion body 14 of the intermediate part of the plate body 2. The chair shown in figure 2 is as in figure 1 , but the chair back is designed with incisions 15-19 so that the plate body 2 becomes flexible and rotatable in this back area.

Stolen 20 i figur 3 er oppbygget av et platelegeme 21, som i figur 1 og 2, men platelegemet 21 er her forbundet med understellets ben 22-25 i et sentralt seteområde 26. For utforming av det ønskede torsjonslegeme er det i platelegemet 21 tatt ut to tverrgående innsnitt 27 og 28. The chair 20 in Figure 3 is made up of a plate body 21, as in Figures 1 and 2, but the plate body 21 is here connected to the legs 22-25 of the chassis in a central seat area 26. For the design of the desired torsional body, the plate body 21 is taken out two transverse incisions 27 and 28.

I figur 4a, b, c er det vist vippebevegelser en sittende person 29 kan utføre sittende på en stol som i figur 1. Figur 4a viser en "normal" sittestilling. I figur 4b lener personen 29 seg bakover og i figur 4c lener vedkommende seg forover. Man ser at setet 7 vil vippe og "forme" seg etter personens 29 lår og sete, muliggjort av torsjonslegemet 14. Figures 4a, b, c show rocking movements a seated person 29 can perform while sitting on a chair as in figure 1. Figure 4a shows a "normal" sitting position. In figure 4b the person 29 leans backwards and in figure 4c the person in question leans forwards. It can be seen that the seat 7 will tilt and "shape" itself to the person's 29 thighs and seat, made possible by the torsion body 14.

En tilsvarende illustrasjon fremgår av 5a-d. Stolen er her utformet med rette og plane sete- og ryggdeler. Figurene illustrerer klart hvordan stolen tilpasser seg til brukerens sittestillinger. A corresponding illustration appears in 5a-d. The chair is here designed with straight and flat seat and back parts. The figures clearly illustrate how the chair adapts to the user's sitting position.

Man vil forstå at innsnittene kan være i form av svekninger i platen, slik at en begrenset vridning muliggjøres. Slike svekkede partier kan også være i form av belg- eller trekkspillignende forbindelser mellom de eller faste platepartier. It will be understood that the incisions can be in the form of weaknesses in the plate, so that a limited twist is made possible. Such weakened parts can also be in the form of bellows or accordion-like connections between them or fixed plate parts.

Ved oppfinnelsen oppnås en form for "dynamisk sitting", hvor man beveger seg med stolen om et fast dreie- eller balanseområde, som fortrinnsvis befinner seg i brukerens balansepunkt (senter av kroppstyngde). The invention achieves a form of "dynamic sitting", where one moves with the chair around a fixed turning or balance area, which is preferably located in the user's balance point (center of body weight).
