Description
Hengsel til stolrygglene. Hinge for the chair backs.
Oppfinnelsen angår et hengsel til ettergivende opphengning av et rygglene til stoler, særlig til kontorstoler og liknende stoler. The invention relates to a hinge for flexible suspension of a backrest for chairs, in particular for office chairs and similar chairs.
Formålet med en ettergivende opphengning av slike rygglener er at rygglenet automatisk skal kunne innta den riktige støttestilling når personen som sit-ter på stolen lener seg tilbake. The purpose of a compliant suspension of such backrests is that the backrest should be able to automatically assume the correct support position when the person sitting on the chair leans back.
Det er kjent å utstyre en slik ettergivende opphengning med et fjærorgan, ved hjelp av hvilket rygglenet, etter at be-lastningen er brakt til opphør, igjen kan føres tilbake til en utgangsstilling. It is known to equip such a yielding suspension with a spring element, by means of which the backrest, after the load has been brought to an end, can again be brought back to an initial position.
Det kjennes forskjellige konstruksjo-ner for slike hengsler, som dels anvender skruefjærer i form av trekkfjærer eller trykkfjærer, dels også spiralfjærer, ved hjelp av hvilke rygglenet kan føres tilbake til utgangsstillingen. ' Various constructions are known for such hinges, which partly use coil springs in the form of tension springs or compression springs, partly also spiral springs, with the help of which the backrest can be returned to the starting position. '
For å tillate en passende ettergivenhet av rygglenet er fjærene akkurat tilstrek-kelig kraftige til å kunne gjennomføre denne tilbakeføring. Hengselforbindelsen mellom rygglenet og stolunderstellet er ganske løs, dels for ikke å skape unødven-dig friksjonstap, dels for å kunne nøye seg med konstruksjonselementer, som er fremstilt i masseproduksjon med ganske store toleranser for å gjøre hengselforbindelsen så billig som mulig. Denne løse opphengning medfører imidlertid at rygglenet for-uten den tilsiktede svingningsmulighet opp og ned også vil kunne vrikke litt i sideret-ningen, hvilket kan være ubehagelig og gi anledning til støy. Anvendelse av fjærer som tilbakeføringsorgan kan likeledes gi anledning til støy, idet fjærer som kjent ofte har tilbøyelighet til å knirke. In order to allow a suitable compliance of the backrest, the springs are just sufficiently strong to be able to carry out this return. The hinge connection between the backrest and the chair base is quite loose, partly to avoid unnecessary friction loss, and partly to be able to make do with construction elements, which are produced in mass production with fairly large tolerances to make the hinge connection as cheap as possible. However, this loose suspension means that the backrest, apart from the intended possibility of swinging up and down, will also be able to wiggle a little sideways, which can be uncomfortable and give rise to noise. The use of springs as a return device can also give rise to noise, as springs, as is well known, often have a tendency to creak.
I motsetning til disse kjente konstruk-sjoner er hengslet ifølge oppfinnelsen, karakterisert ved at det består av et kautsjuklegeme i form av en dor som strekker seg hovedsakelig vinkelrett på rygglenets plan og er fast forbundet med såvel rygg-" lenet som støtteorganet. In contrast to these known constructions, the hinge according to the invention is characterized in that it consists of a rubber body in the form of a mandrel which extends mainly perpendicular to the plane of the backrest and is firmly connected to both the backrest and the support member.
Det vil forståes at et rygglene som er opphengt ved hjelp av et slikt kautsjuklegeme vil være ettergivende tvangsstyrt for alle bevegelser, og at dette hengsel vil arbeide fullstendig lydløst uten klap-ring av metalliske hengseldeler og uten knirking av spennfjærer. Det skal enn-videre forståes at hengslet ifølge oppfinnelsen er meget enkelt og derfor vil kunne fremstilles billig. It will be understood that a backrest which is suspended by means of such a rubber body will be yielding force-controlled for all movements, and that this hinge will work completely silently without clattering of metallic hinge parts and without creaking of tension springs. It should also be understood that the hinge according to the invention is very simple and will therefore be able to be produced cheaply.
For å lette såvel kautsjuklegemets an-bringelse som en eventuell utskiftning av legemet, kan det ifølge oppfinnelsen være hensiktsmessig at kautsjuklegemet er fastholdt delvis til stolens understell og delvis til rygglenet ved hjelp av et avtagbart beslag. In order to facilitate both the placement of the rubber body and a possible replacement of the body, according to the invention it may be appropriate that the rubber body is secured partly to the chair's base and partly to the backrest by means of a removable fitting.
En hensiktsmessig utførelsesform kan ifølge oppfinnelsen tilveiebringes ved at kauts juklegemet er utformet som en bolt, som består av en skaftdel og en skulder som er anbrakt på skaftdelens ene ende, mens skaftdelens annen, fri ende er innrettet til å fastholde stolunderstellet, og at beslaget består av en ryggplate, som har et hull hvis diameter svarer til skaftdelens og som er innrettet til å festes på rygglenet med skulderen anbrakt mellom ryggplaten According to the invention, a suitable embodiment can be provided by the fact that the yoke body is designed as a bolt, which consists of a shaft part and a shoulder which is placed on one end of the shaft part, while the other, free end of the shaft part is designed to hold the chair base, and that the fitting consists of a back plate, which has a hole whose diameter corresponds to that of the shaft part and which is adapted to be attached to the backrest with the shoulder placed between the back plate

nom hullet, og av minst én flik, som er anbrakt på ryggplaten ved siden av hullet og derfra strekker seg under en vinkel med ryggplaten i praktisk talt samme retning som boltens skaftdel, når bolten er anbrakt i ryggplaten, hvilken flik eller hvilke fliker er innrettet til svingbar opphengning på stolunderstellet. Som følge av flikenes og derved hele beslagets svingbare oppheng- nom the hole, and of at least one tab, which is placed on the back plate next to the hole and thence extends at an angle with the back plate in practically the same direction as the shank part of the bolt, when the bolt is placed in the back plate, which tab or tabs are aligned for swiveling suspension on the chair frame. As a result of the hinged suspension of the tabs and thereby the entire fitting
ning er også hengselforbindelsens bevege- ning is also the movement of the hinge connection
lighet begrenset til bare å kunne foregå possibility limited to only being able to take place
i en enkelt retning, dvs. i retning opp og ned. in a single direction, i.e. up and down.
En enkel og hensiktsmessig utform- A simple and appropriate design
ning av denne konstruksjon kan således ifølge oppfinnelsen tilveiebringes ved at stolunderstellet, beslagets flik eller fliker og boltens skaftdel er utstyrt med korre-sponderende huller, hvorigjennom det er ført en hengselstift. Denne hengselstift vil således ikke bare tjene som svingtapp for beslaget, men også som holdeorgan for kau ts juklegemet, slik at dette ikke kan forskyves når det påvirkes. ning of this construction can thus, according to the invention, be provided by the chair base, the tab or tabs of the fitting and the shaft part of the bolt being equipped with corresponding holes, through which a hinge pin is inserted. This hinge pin will thus not only serve as a pivot pin for the fitting, but also as a holding device for the cow's yoke body, so that this cannot be displaced when it is affected.

er fremstilt i henhold til oppfinnelsen skal i det følgende beskrives under henvisning til tegningen. is produced in accordance with the invention shall be described in the following with reference to the drawing.
