Description

Kontorstol.
Der er tidligere i og for seg kjent ved kontorstoler å anvende en fjær for å lette re-guleringen av vanlige høydeinnstillbare stol-seter.
Denne oppfinnelse vedrører en kontorstol
av den art, ved hvilken setet er fastgjort på en nedad rettet stang, som er forskyvbart lagret i et av benene bærende organ (benkrysset) og ved hvilken der på stangen finnes
en forskyvbar og fastklembar muffe, som bærer et anslagsorgan for den øverste ende av en stangen omsluttende skruef jær, hvis nederste ende ligger an mot det benene bærende organ, således at en belastning på setet vil forplante seg gjennom stangen og muffen til fjæren, som derved trykkes sammen.
Oppfinnelsen utmerker seg hovedsakelig
ved at der mellom muffen og setet er anbragt ytterligere en stangen omsluttende skrufjær som ved løs klemhylse søker å løfte setet i forhold til benkrysset og er vesentlig bløtere enn den fjær som er anbragt mellom muffen og det med benene forbundne organ således at man i halvveis sittende og halveis stående stilling kan høyderegulere stolen.
En utførelsesform er vist på tegningen i oppriss og snitt etter setestammerørets akse.
1 er en del av stolens sete til hvilket er festet den øvre ende av et vertikalt rør 2 som
fortsetter nedover gjennom benkrysset 13, hvilket er forsynt med en fast hylse 3 med øvre endeforing 4 og nedre endeforing 5, hvori røret 2 kan gli i vertikal retning. Røret er forøvrig nedenfor hylsen 3 forsynt med en stoppskrue 6, hvis hensikt senere skal forkla-res. Røret 2 er oventil omsluttet av et kort distanserør 7, som er i fast forbindelse med setekrysset 1.
Røret 2 er videre omsluttet av en klemhylse 8 som kan spennes omkring røret ved hjelp av en skrue 9 på vanlig måte, således at
hylsen 8 kan forbindes fast med røret 2 efter at dette er blitt innstilt i passende høyde. Hylsen 8 er sveiset fast til den øvre del 10a av et kulelager, hvis nedre del 10b danner holder for den øvre ende av en vanlig fjær 11 som om-slutter setestammerøret 2 og hvis nedre ende har anlegg på et særskilt stykke 12 festet på oversiden av benkrysset 13.
Denne anordning er tidligere kjent og gjør det mulig å innstille setet i den ønskede høyde efter at skruen 9 er losnet, hvoretter skruen trekkes til så hylsen 8 forbindes fast med røret 2.
Som det sees, er det mellom klemhylsen 8 og en liten skål 14 under setekryssets tverr-kanal innskutt en ekstra fjær 15, som søker å
løfte setet i forhold til benkrysset 13 når hylsen 8 er løsnet. Man kan da i halvveis sittende og halvveis stående stilling høyderegu-lere stolsetet. Fjæren 15 har i ekspandert til-stand en lengde som svarer til stolens høyeste innstilling. For å fiksere denne er den omtal-te skrue 6 anbragt på den nederste del av se-testammerøret 2. I setets høyeste stilling vil skruen 6 slå mot styringen 5 i benkrysset 13.
På setestammerøret 2 er det dessuten som nevnt under setekrysset anordnet en hylse 7, som har en sådan lengde at den slår mot hylsen 8 når fjæren 15 har den største sam-mentrykning som ønskes.

Claims (3)

1. Kontorstol av den art, ved hvilken setet er fastgjort på en nedad rettet stang, som er forskyvbart lagret i et benene bærende
organ, benkrysset, og ved hvilken der på stangen finnes en forskyvbar og fastklembar muffe, som bærer et anslagsorgan for den øverste ende av en stangen omsluttende skruefjær, hvis nederste ende ligger an mot det benene bærende organ, således at en belastning på setet vil forplante seg gjennom stangen og muffen til fjæren, som derved trykkes sammen, karakterisert ved at der mellom muffen (8) og setet (1) er anbragt ytterligere en stangen (2) omsluttende skruefjær (15), som er vesentlig bløtere enn den mellom muffen (8) og det med benene forbundne organ (13) anbragte fjær (11).
2. Kontorstol ifølge påstand 1, karakterisert ved at der på den nederste del av stangen (2) er således anbragt et stoppeorgan (6), at det vil støte mot en del (5) på det benene bærende organ (13), når stangen (2) løftes oppad.
3. Kontorstol ifølge påstand 1—2, karakterisert ved at der på setet (1) er således anbragt en nedadrettet og stangen (2) omsluttende bøssing (7), at den vil støte mot muffen (8), når stangen (2) beveges nedad i forhold til muffen (8).
