Den foreliggende opfindelse vedrører en stol udstyret med omstil bar lægstøttedel, omfattende en stol underdel, som understøtter en stol overdel, hvor stoloverdelen fortrinsvis er svingbar om en vertikal akse i forhold til stol underdel en, og hvor stol overdel en omfatter et sædeparti 5 med tilhørende rygstødsparti samt en i forhold til sædepartiet omstilbar lægstøttedel, som kan omstilles på trinløst regulerbar måde imellem inaktiv stilling, afskærmet på undersiden af sædepartiet, og aktiv læg-støttestilling foran sædepartiet ved hjælp af et par eller et sæt af indbyrdes parallelle, i længden forskydelige støtteorganer.BACKGROUND OF THE INVENTION The present invention relates to a chair equipped with adjustable leg support part, comprising a chair lower part, which supports a chair upper, the chair upper being preferably pivotable about a vertical axis relative to the chair lower part, and wherein the chair upper one comprises a seat portion 5 with associated a backrest portion and an adjustable leg support portion adjustable relative to the seat portion, which can be switched in an infinitely controllable manner between inactive position, shielded on the underside of the seat portion, and active leg support position in front of the seat portion by means of a pair or set of mutually displaceable longitudinal support members .
10 I forbindelse med stole, især lænestole, er det sædvanligt at benytte en lægstøttedel i form af en separat skammel. Et første problem ved sådanne separate skamler er, at de kræver ekstra plads i inaktiv eller ubrugt tilstand. Et andet problem er, at sådanne separate skamler, når de er i brug, må forskydes på underlaget, alt efter om brugeren af 15 stolen forskyder eller svinger den tilhørende stol rundt. Det har været foreslået at fastgøre lægstøttedelen til stolen via en ledforbindelse ved sædedelens nedre forkantsparti og at svinge lægstøttedelen fra en mere eller mindre horisontal eller skråt udad og skråt nedad forløbende, aktiv 1ægstøttesti11 i ng foran stol overdelens sædeparti til en inaktiv, 20 vertikalt forløbende stilling langs forkanten af stol underdel en. I aktiv lægstøttestilling vil nødvendige støtteorganer mellem stolen og lægstøt-tedelen i stærk grad påvirke og skæmme stolens udseende, mens lægstøtte-delen i sig selv vil påvirke og skæmme stolens udseende i lægstøttede-lens nedad forløbende, inaktive stilling.10 In the case of chairs, especially armchairs, it is usual to use a leg support part in the form of a separate stool. A first problem with such separate stools is that they require extra space in idle or unused condition. Another problem is that such separate stools, when in use, must be displaced on the substrate, depending on whether the user of the chair displaces or swivels the associated chair around. It has been proposed to attach the leg support portion to the chair via a linkage at the lower front edge of the seat portion and to swing the leg support portion from a more or less horizontal or inclined outward and inclined downwardly active active support post 11 in front of the chair upper portion of the seat to an inactive, vertically extending along the front of chair lower part one. In active leg support position, the necessary support members between the chair and the leg support portion will greatly affect and damage the appearance of the chair, while the leg support portion itself will affect and impair the appearance of the chair in the downwardly inactive position of the leg support.
25 Fra FI fremlæggelsesskrift nr. 67 174 og US patent nr. 2 919 746 kendes en svingbar benstøttedel, som kan svinges fra en inaktiv stilling på undersiden af stolesædet til en aktiv stilling foran stolesædet. Stolesædet og benstøtten udgør en sammenhængende enhed.25 From FI Patent Specification No. 67,174 and U.S. Patent No. 2,919,746, a pivotable leg support portion is known which can be pivoted from an inactive position on the underside of the seat to an active position in front of the seat. The seat and legrest form a cohesive unit.
Fra FR patent nr. 1 315 414 og US patent nr. 4 515 407 kendes en 30 aksialt bevægelig benstøttedel, som er fysisk adskilt fra stolesædet, og som kan danne støtte i forskellige afstande fra stolesædet.From FR Patent No. 1,315,414 and US Patent No. 4,515,407, there is known an axially movable leg support member which is physically separated from the seat and which can support at different distances from the seat.
Ved stole, hvor stol overdel en frit skal kunne svinges om en vertikal akse i forhold til stol underdelen, må lægstøttedelen i sin helhed, dvs. inklusive de nødvendige støtteorganer, fastgøres til stol overdel en.In the case of chairs where the chair upper can be freely pivoted about a vertical axis relative to the chair lower, the leg support part must be in its entirety, ie. including the necessary support means, attached to the chair upper one.
35 En sådan udførelse kan medføre betydelige komplikationer for fri og u-hindret svingning af stol overdel en i forhold til stol underdel en.35 Such an embodiment can cause considerable complications for free and unobstructed swinging of chair upper one relative to chair lower part one.
Med den foreliggende opfindelse tager man sigte på en stol, hvor lægstøttedelen, såvel i aktiv benstøttestilling som i inaktiv stilling,The present invention is directed to a chair in which the leg support portion, both in active leg support position and in the inactive position,
DK 165478 BDK 165478 B
2 kan indgå i stolen uden væsentligt at påvirke stolens udseende. Med andre ord tager man sigte på at indarbejde lægstøttedelen med et minimalt pladsbehov i stolen, således at stolen uden ekstra modifikationer kan udformes med en række forskellige, æstetisk tiltalende, forholdsvis 5 slanke formgivninger i moderne udførelse.2 can be included in the chair without significantly affecting the appearance of the chair. In other words, the aim is to incorporate the leg support part with a minimal space requirement in the chair, so that the chair can be designed without any additional modifications with a number of different, aesthetically pleasing, relatively 5 slim designs in modern design.
Specielt, men ikke udelukkende, tager man sigte på en lægstøttedel, som kan benyttes i forbindelse med stole, hvor stol overdel en kan svinges om en vertikal akse i forhold til stol underdel en.Particularly, but not exclusively, one aims at a leg support part which can be used in connection with chairs, where chair upper one can be pivoted about a vertical axis in relation to chair lower one.
Dette opnås ifølge opfindelsen ved, at lægstøttedelen dannes af et 10 polstret, i tværretningen afstivet, baneformet parti, og at det baneformede parti forløber i en sløjfe over et eller flere modsvarende buede føringsorganer, fastgjort til yderenden af støtteorganernes bæredele, samt at det baneformede parti har sin ene ende forløbende i forlængelse af sædedelens sædeparti og sin modsatte ende fastgjort til sædedelens 15 underside, fortrinsvis via en længdekompenseringsanordning mellem bæredelen og en tilhørende holderdel.This is achieved according to the invention in that the leg support portion is formed by a padded, transversely stiffened, web-shaped portion, and the web-shaped portion extends in a loop over one or more correspondingly curved guide members, attached to the outer end of the support members, and the web-shaped portion. has one end extending in extension of the seat portion of the seat portion and its opposite end attached to the underside of the seat portion 15, preferably via a length compensation device between the carrier portion and an associated holder portion.
Herved kan man opnå flere fordele, for eksempel at lægstøttedelen kan forskydes i forskellig udstrækning foran sædepartiet, efter behov og alt efter brugerens benlængde, uden at sådan regulerbar omstilling i væ-20 sentlig grad indvirker på lægstøttedelens generelle form. I den anledning er det fordelagtigt, at det baneformede parti, eftersom det trækkes udad fra stol overdel en, kan give effektiv sideafskærmning for lægstøttedel ens omstillingsmekanisme, indbefattet støtteorganer m.m. ved en enkel afrulning af det baneformede parti i forhold til omstil!ingsmekanismen.Thereby, several advantages can be obtained, for example that the leg support part can be displaced to a different extent in front of the seat portion, as needed and according to the user's leg length, without such an adjustable adjustment having a significant effect on the general shape of the leg support part. For this reason, it is advantageous that the web-shaped portion, as it is pulled outward from the chair upper one, can provide effective side shielding for the leg support part's similar switching mechanism, including support means and the like. by a simple roll-off of the web-shaped portion in relation to the adjustment mechanism.
25 Yderligere træk ved opfindelsen vil fremgå af den efterfølgende beskrivelse under henvisning til den medfølgende tegning, hvori fig. 1 og 2 viser en lægstøttedel ifølge opfindelsen i forbindelse med en lænestol, hvis stol underdel er udstyret 30 med fire ben, vist med lægstøttedelen i inaktiv hen holdsvis aktiv stilling, fig. 3 og 4 viser en lægstøttedel ifølge opfindelsen i forbindelse med en lænestol, hvis stoloverdel er svingbart lejret om en vertikal akse i forhold til stolunder-35 delen, vist med lægstøttedelen i inaktiv henholdsvis aktiv stilling, fig. 5 og 6 viser skematisk og i perspektiv en lægstøttedel i en første, enkel, manuelt drevet udførelse, vist med 3Further features of the invention will become apparent from the following description with reference to the accompanying drawings, in which: FIG.

4 bøjleparti 42 med et par af indbyrdes modstående føringshjul 43, hvorfra et tilhørende håndtag 44 rager ud på hver side af lægstøttedelen. Alternativt kan der, i stedet for de viste to føringshjul, benyttes tre eller flere føringshjul på række eller en sammenhængende føringsrulle. Fir-5 kantrammen 41 omfatter to kanal formede holderdele 41a og 41b med mod hinanden rettede kanal åbninger, hvor holderdelene er indbyrdes afstivede via tværgående afstivningsdele 41c og 41d. Bøjlepartiet omfatter to støttedele 42a og 42b, som ved yderenden er forbundet med hinanden ved hjælp af en tværgående afstivningsdel 42c. Støttedelene 42a og 42b er 10 aksialt forskydelige i hver sin holderdel 41a og 41b som vist i fig. 5 og 6.4 hanger portion 42 with a pair of mutually opposed guide wheels 43, from which an associated handle 44 protrudes on each side of the leg support portion. Alternatively, instead of the two guide wheels shown, three or more guide wheels may be used in a row or a continuous guide roller. The square edge frame 41 comprises two channel-shaped support portions 41a and 41b with mutually directed channel openings, the support portions being mutually stiffened via transverse stiffener portions 41c and 41d. The hanger portion comprises two support portions 42a and 42b which are joined at the outer end by a transverse stiffener portion 42c. The support members 42a and 42b are axially displaceable in each of their support members 41a and 41b as shown in FIG. 5 and 6.
I det viste udførelseseksempel er vist retløbende holderdele og retløbende støttedele, således at føringshjulene kan forskydes retlinet mellem inaktiv stilling, som vist i fig. 5, og aktiv stilling, som vist 15 i fig. 6. I det vi'ste udførelseseksempel er vist omstillingsmekanismen, forløbende parallelt med stoloverdelens sædeparti, som i praksis oftest har et noget bagud hældende forløb. For at lægstøttedelen skal få et skråt udad- og nedadrettet forløb i forhold til sædedelen, kan firkantrammen 41 være modsvarende skråtstillet i forhold til sædepartiet. Al-20 ternativt eller yderligere kan holdedelene og støttedelene have et i længderetningen buet forløb, således at føringshjulene samtidig med, at de forskydes udad, også forskydes nedad. Herved kan man samtidig med, at man forskyder føringshjulene en regulerbar længde fremfor sædepartiet, i stærkere grad også forskyde føringshjulene til regulerbare højder i for-25 hold til sædepartiet.In the exemplary embodiment shown, rectangular support members and rectangular support members are shown so that the guide wheels can be displaced rectilinearly between inactive position, as shown in FIG. 5, and active position, as shown in FIG. 6. In the second embodiment, the adjustment mechanism is shown, running parallel to the seat portion of the chair upper, which in practice usually has a somewhat backward slope. In order for the leg support part to have an inclined outward and downward direction relative to the seat part, the square frame 41 can be correspondingly inclined with respect to the seat portion. Alternatively or further, the holding members and the supporting members may have a longitudinally curved course so that the guide wheels, while being displaced outwards, can also be shifted downwards. Hereby, while displacing the guide wheels an adjustable length in front of the seat portion, it is also possible to shift the guide wheels to adjustable heights in proportion to the seat portion.
I fig. 7 og 8 er vist forløbet af det baneformede materiale 40a i en sløjfe om føringshjulene 43. Materialets 40a frie endekant 40b er ved hjælp af træksnore 45 forbundet med forkanten af en tilhørende holderdel 41b (41a). Træksnorene 45 forløber i en sløjfe om hvert sit vendehjul 46 30 på en konsol 47 på støttedelenes 42b (42a) styringsdannende endeparti, til dannelse af en længdekompenseringsindretning for det baneformede materiale.In FIG. 7 and 8, the course of the web-shaped material 40a is shown in a loop around the guide wheels 43. The free end edge 40b of the material 40a is connected to the leading edge of an associated holder part 41b (41a) by means of the drawstring 45. The pull cords 45 extend in a loop about each of their turning wheels 46 30 on a bracket 47 on the guide forming end portion of the support members 42b (42a) to form a length compensation device for the web-shaped material.
I fig. 9 er vist det baneformede materiale 40a, fastgjort til en jalousi-lignende afstivningsplade 48, dannet af en række tværgående, si-35 deværts indbyrdes sammenhængslede afstivningslameller 49, som er indbyrdes sammenhængslet via ribbeformede fremspring 49a i den ene sidekant og tilhørende spor 49b i den modsatte sidekant. Materialet 40a kan være forbundet med lægterne 49 ved lægternes endekanter og kan derfra rage etIn FIG. 9, the web-shaped material 40a is attached to a jalousi-like stiffening plate 48, formed by a series of transverse, laterally interconnected stiffening slats 49, which are interconnected via rib-shaped projections 49a in one side edge and associated groove 49b thereof. opposite side edge.
