Opfindelsen angår et siddemøbel med et stel med mindst to indbyrdes adskilte sidedele, der bærer en sædeflade og en rygflade hver bestående af et antal kontinuerlige, bugtede fjedertråde beklædt med en tynd 5 plastbelægning, der omslutter de enkelte tråde og sammenholder disse indbyrdes på de steder, hvor de nærmer sig hinanden, så at plastbelægningen dér danner bro mellem trådene og sammenholder disse til et cylindrisk hvælvet, fjedrende aggregat, der er anbragt på stellet i 10 fjedrende udspændt og affladet tilstand.The invention relates to a seat piece of furniture with a frame with at least two mutually separated side parts, carrying a seat surface and a back surface each consisting of a number of continuous, curved spring wires lined with a thin plastic coating enclosing the individual wires and holding them together in the places where they approach each other so that the plastic coating there forms a bridge between the wires and holds them together into a cylindrically domed, resilient assembly arranged on the frame in a resiliently stretched and flattened condition.
Siddemøblet ifølge opfindelsen er ejendommeligt ved, at de sædeflade og rygflade dannende aggregater buer henholdsvis opad og bagud og er så tynde og således afpasset efter hinanden, at de kan finde plads det ene 15 inden i det andet ved opklapning af sædet på et som klapstol udformet siddemøbel og ved stabling oven på hinanden af som stabelstole udformede siddemøbler.The seating furniture according to the invention is characterized in that the seat surface and back surface forming aggregates bend upwards and rearwards, respectively, and are so thin and thus adapted to each other that they can fit one inside the other by folding up the seat on a folding chair seating furniture and when stacking on top of each other of seating furniture designed as stacking chairs.
Herved opnås fordelene både ved anvendelse af fjedrende aggregater som de angivne og ved, at stellet 20 består af særskilte, stive steldele.Hereby the advantages are obtained both by using resilient units as those indicated and by the frame 20 consisting of separate, rigid frame parts.
Således kan stellet i særlig fordelagtige udformninger være indrettet til at klappe sædet op, så at det kommer til at ligge inden i ryggen med sin underside liggende inden for korden tværs over ryggen.Thus, in particularly advantageous designs, the frame can be arranged to fold up the seat so that it comes to lie inside the back with its underside lying within the cord across the back.
25 Stellet kan ogSå være stableligt' på et lignende ' stel med sæderne sat således ind i hinanden, at undersiden af heders te sæde-ligger inden for korden tværs over buen af det øvre jsæde, og at den forréste side af ryggen ligger inden for korden tværs over buen af den 30 neden under værende ryg.The frame can also be stacked 'on a similar' frame with the seats inserted so that the underside of the heath tea seat lies within the cord across the arch of the upper seat and that the front side of the back is within the cord. across the arch of the 30 below being back.
Disse to udformninger giver et siddemøbel ifølge opfindelsen muligheden for ved sajmenklapning eller stabling at optage lille plads ved transport og opbevaring.These two designs give a seating piece of furniture according to the invention the possibility of taking up small space during transport and storage by folding or stacking.
35 Opfindelsen forklares nærmere i det følgende ved hjælp af udførelseseksempler ifølge opfindelsen 145406 2 og under henvisning til tegningen, hvorpå fig. 1 viser i perspektiv en stol, som anvender principperne ifølge opfindelsen, fig. 2 i perspektiv og i forhold til fig. 1 5 i større målestok et sæde eller et rygaggregat ifølge opfindelsen før montering på stolestellet i fig. 1, fig. 3 skematisk i endebillede forskellen mellem radien af det cylindriske aggregat i fig. 2 og det 10 monterede sæde i fig. 1, som er noget fladet ud, hvorved fjedertrådene sættes under træk, fig. 4 et perspektivbillede af et andet udførelseseksempel på en stol, som anvender principperne ifølge opfindelsen, og i hvilken sæde- og rygaggrega-15 tet er monteret således i et stel, at der tilvejebringes dobbeltkrumme flader, fig. 5 et sidebillede af stolen i fig. 4, fig. 6 et sidebillede af en udslået sammenfoldelig stol, som anvender principperne ifølge opfin-20 delsen, fig. 7 et sidebillede af den sammenfoldelige stol i fig. 6 i sammenfoldet, tilstand, og fig. 8 et skematisk billede af de relative buer og radier af ryg og sæde til.stolen i fig. 6.The invention is explained in more detail in the following by means of exemplary embodiments according to the invention 145406 2 and with reference to the drawing, in which fig. 1 shows in perspective a chair which applies the principles according to the invention, fig. 2 in perspective and in relation to FIG. 1 5 on a larger scale a seat or a backrest according to the invention before mounting on the chair frame in fig. 1, fig. 3 is a schematic end view of the difference between the radius of the cylindrical assembly of FIG. 2 and the seat mounted in FIG. 1, which is somewhat flattened, whereby the spring wires are put under tension, fig. Fig. 4 is a perspective view of another embodiment of a chair which applies the principles according to the invention, and in which the seat and back assembly is mounted in such a frame that double-curved surfaces are provided; 5 is a side view of the chair of FIG. 4, fig. Fig. 6 is a side view of a folded-out folding chair which applies the principles according to the invention; 7 is a side view of the folding chair of FIG. 6 in the fold, condition, and FIG. 8 is a schematic view of the relative arches and radii of the back and seat of the chair of FIG. 6.
25 Principperne ifølge opfindelsen kan anvendes til mange typer siddemøbler, f.eks. stole, sofaer, sovesofaer, bænke, taburetter, automobilsæder, bussæder, lejrstole etc.The principles of the invention can be applied to many types of seating furniture, e.g. chairs, sofas, sofa beds, benches, stools, car seats, bus seats, camp chairs etc.
Et eksempel på en type siddemøbel, som kan 30 anvende principperne ifølge opfindelsen, er i fig. 1 vist som en stol 60.An example of a type of seating furniture which can apply the principles according to the invention is shown in fig. 1 shown as a chair 60.
Denne har forben 61 og 62 og bagben 63 og 64, som fortsætter opad fortrinsvis under en vinkel til dannelse af rygsteldele 65 og 66. Vandrette 35 sidedele 67 og 68 i stellet forbinder forbenene 61 og 62 med bagbenene 63 og 64, hvor disse møder 145406 3 stellets rygdele 65 og 66. I dette specielle udførel-seseksempel er rygsteldelene 65 og 66 holdt stift indbyrdes parallelle og sidesteldelene 67 og 68 holdt stift indbyrdes, parallelle. Denne parallelitet- _ 5 behøver ikke altid at være til stede, men er foretrukket .This has front legs 61 and 62 and hind legs 63 and 64, which continue upwards preferably at an angle to form back frame parts 65 and 66. Horizontal 35 side parts 67 and 68 in the frame connect the front legs 61 and 62 with the rear legs 63 and 64, where they meet 145406 3 the back parts 65 and 66 of the frame. In this particular exemplary embodiment, the back frame parts 65 and 66 are kept rigidly parallel to each other and the side frame parts 67 and 68 are kept rigidly parallel to each other. This parallelism does not always have to be present, but is preferred.
Et sædeaggregat 70 bæres af sidesteldelene 67 og 68, og et rygaggregat 70A bæres af steldelene 65 og 66. Sædeaggregatet 70 og rygaggregatet 10 70a ligner hinanden meget. De kan i nogle tilfælde være ens, men sædvanligvis er rygaggregatet 70A noget mindre end sædeaggregatet 70 og er sædvanligvis fremstillet af en tråd med mindre tværsnit.A seat 70 is carried by the side frame portions 67 and 68, and a back assembly 70A is carried by the frame members 65 and 66. The seat 70 and the back assembly 10a 70a are very similar. They may be similar in some cases, but usually the back assembly 70A is somewhat smaller than the seat assembly 70 and is usually made of a wire of smaller cross-section.
Fig. 2 viser sædeaggregatet 70, før det er 15 indsat i stolen. Figuren viser også i princippet, hvordan rygaggregatet 70A ser ud, selv om dette om ønsket kan være forskelligt i størrelse eller i konstruktion eller udseende. . i I dette eksempel omfatter aggregatet 70 en 20 ramme 71 med indbyrdes adskilte lige ender 72 og 73 forbundet af parallelle sidestykker 74 og 75, som, er formet som cirkulære buer. De lige endestykker 72 og 73 er bestemt til at fastgøres til sidesteldelene 67 og 68 på stolen og går således fra for-25 side til bagside på hver side af stolen 60, medens sidestykkerne 74 og 75 bliver for- og bagkanter af sædet på den samlede .stol 60. Men hvad angår selve sædeaggregatet 70, er delene 72 og 73 enderne, og sidestykkerne 74 og 75 er buede eller cirkulære 30 sider.FIG. 2 shows the seat unit 70 before it is 15 inserted in the chair. The figure also shows in principle what the back unit 70A looks like, although this may, if desired, be different in size or in construction or appearance. . In this example, the assembly 70 comprises a frame 71 with mutually spaced straight ends 72 and 73 connected by parallel side pieces 74 and 75, which are formed as circular arcs. The straight end pieces 72 and 73 are intended to be attached to the side frame portions 67 and 68 of the chair and thus go from front to back on each side of the chair 60, while the side pieces 74 and 75 become front and rear edges of the seat on the assembly. .chair 60. But as for the seat 70 itself, the parts 72 and 73 are the ends and the side pieces 74 and 75 are curved or circular 30 sides.
Fra ende til ende på tværs af de to endestykker 72 og 73 ligger et stort antal bugtede fjedertråde 76, 76a, 76b ..... 76n, som er buet i en cirkulær bue af samme størrelse og form som sidestykkerne 35 74 og 75. Disse fjedre 76, 76a etc. kan have mange faconer. Typiske tråde hertil er af fjederstål med U5406 4 0,60%-0,75% kulstof og 0,90%-1,20% mangan. Trækstyrken 2 ligger typisk på ca. 15100-18600 kg/cm og deres Rockwell hårdhed på ca. 39-41 RC. Diameteren af trådene ligger fortrinsvis i området 1,3-3,8 mm. For tyk en tråd 5 har tendens til at koncentrere stivheden for meget, og sædet bliver for fast, medens for tynd en tråd gør sædet for blødt.From end to end across the two end pieces 72 and 73 lies a large number of curved spring wires 76, 76a, 76b ..... 76n which are curved in a circular arc of the same size and shape as the side pieces 35 74 and 75. These springs 76, 76a etc. can have many shapes. Typical wires for this are of spring steel with U5406 4 0.60% -0.75% carbon and 0.90% -1.20% manganese. The tensile strength 2 is typically approx. 15100-18600 kg / cm and their Rockwell hardness of approx. 39-41 RC. The diameter of the wires is preferably in the range 1.3-3.8 mm. Too thick a thread 5 tends to concentrate the stiffness too much and the seat becomes too firm, while too thin a thread makes the seat too soft.
Begge ender af hver fjeder 76 er fast forbundet til og fastgjort til et af endestykkerne 72 og 10 73 i rammen 71. Der kan anvendes forskellige organer til opnåelse af denne faste forankring, såsom friktionsgribende organer og svejsning.Both ends of each spring 76 are fixedly connected to and attached to one of the end pieces 72 and 73 in the frame 71. Various means can be used to obtain this fixed anchorage, such as friction gripping means and welding.
Fjedrene 76, 76a, 76b ..... 76n er place ret således, at de tangerer hinanden, og hver af de to 15 yderste fjedertråde 76 og 76n tangerer hovedsagelig ved hver hele bugtning et af sidestykkerne 74 Qg 75. Hver tråd 76 rører sine nærliggende tråde mindst én gang pr. bugtning. Berøringen kan være virkelig kontakt, eller den kan være næsten berøring eller tæt til-20 nærmelse, fordi aggregatet 70 holdes sammen på en måde, som ikke kræver virkelig fysisk kontakt af metallet ved hvert tangentpunkt, men der er altid en meget tæt indbyrdes beliggenhed om ikke virkelig berøring.The springs 76, 76a, 76b ..... 76n are positioned so that they are tangent to each other, and each of the two outermost spring wires 76 and 76n substantially at each entire bend bends one of the side pieces 74 Qg 75. Each wire 76 touches its nearby threads at least once per curvature. The touch can be real contact, or it can be almost touch or close proximity, because the assembly 70 is held together in a way that does not require real physical contact of the metal at each tangent point, but there is always a very close mutual position. not really touch.
En tynd bøsningsformet plastbelægning 79 25 omgiver fjedertrådene 76, idet dén følger deres bugtede facon og bygger bro mellem trådene 76, 76a etc. hvor de helt eller hovedsagelig rører hinanden. Plastbelægningen 79's tykkelse er fortrinsvis ca. halvdelen af trådtykkelsen eller i området fra ca. en femtedel af 30 trådtykkelsen til ca. lig med trådtykkelsen. Ved forbindelsesstederne kan tykkelsen være betydelig større.A thin sleeve-shaped plastic coating 79 surrounds the spring wires 76, following their curved shape and bridging the wires 76, 76a, etc. where they completely or substantially touch each other. The thickness of the plastic coating 79 is preferably approx. half the wire thickness or in the range from approx. one-fifth of the wire thickness to approx. equal to the wire thickness. At the connection points, the thickness can be considerably greater.
Denne plastbelægning 79 omgiver også rammen 71 og lænker trådene 76 og ende- og sidestykkerne af rammen 71 sammen til et samlet aggregat 70. Plastbe-35 lægningen 79 holder trådene 76 til hinanden, når de spænder over rammeenderne 72 og 73, og den holder 1Λ 5 Λ O 6 5 sidetrådene 74 og 75 til de yderste fjedertråde 76 og 76n i alle tangentpunkter. Resultatet er den krumme eller cylindriske bueform, som typisk ligner den i fig. 2 viste, selv om buen kan være noget fladere 5 eller noget mere krum.This plastic coating 79 also surrounds the frame 71 and links the wires 76 and the end and side pieces of the frame 71 together into an assembled assembly 70. The plastic coating 79 holds the wires 76 together when they span the frame ends 72 and 73, and it holds 1 5 Λ O 6 5 the side wires 74 and 75 to the outermost spring wires 76 and 76n at all tangent points. The result is the curved or cylindrical arcuate shape which is typically similar to that of FIG. 2 showed, although the arc may be somewhat flatter 5 or somewhat more curved.
Det samlede aggregat 70 er således et aggregat, der kan håndteres og transporteres som en enhed og kan samles med stolen 60 i fig. 1 eller med mange andre typer stole, så længe den rigtige størrelse og form 10 er til stede på den ene eller den anden måde, dvs. enten ved at selve stolen er formet til at passe til sædeaggregatet 70, eller saadeaggregatet 70 selv er fremstillet således, at det vil passe med et stolestel eller anden type af stel til et siddemøbel. Selve aggre-15 gatet 70 kan masseproduceres og kan let samles med en stol eller et andet siddemøbel ved at de to endestykker 72 og 73 fastgøres til et passende stift stel.The assembled assembly 70 is thus an assembly that can be handled and transported as a unit and can be assembled with the chair 60 in fig. 1 or with many other types of chairs, as long as the right size and shape 10 is present in one way or another, i.e. either by the chair itself being shaped to fit the seat 70, or the seat 70 itself being made to fit a chair frame or other type of seat furniture seat. The aggregate hole 70 itself can be mass-produced and can be easily assembled with a chair or other piece of seating furniture by attaching the two end pieces 72 and 73 to a suitable rigid frame.
Fig. 3 viser skematisk, hvad der sker, når aggregatet 70 i fig. 2 sættes på stolen 60 i fig.FIG. 3 shows schematically what happens when the assembly 70 in fig. 2 is placed on the chair 60 in fig.
20 1. Den runde cylindriske bue i fig. 2 med radius R1 flades ud fra den facon, som er vist forneden i fig. 3, til den facon, som er vist foroven i samme figur, hvor den har en større radius R2. Aggregatet 70 får dermed en bredere spændevidde, og dets bue er fladet 25 noget ud, således at det kan anvendes som et sæde.20 1. The round cylindrical arc of FIG. 2 with radius R1 is flattened out from the shape shown below in fig. 3, to the shape shown above in the same figure, where it has a larger radius R2. The unit 70 thus has a wider span, and its arch is flattened out somewhat so that it can be used as a seat.
Det har en pilhøjde h, som er vist på tegningen, og-det er stadig en cylindrisk bue, selv om den er væsentlig fladere.It has an arrow height h, which is shown in the drawing, and-it is still a cylindrical arc, although it is significantly flatter.
Denne udfladning af et rundt aggregat er en 30 vigtig egenskab ifølge opfindelsen. Ved at forme aggregatet 70 til at begynde med som en cylindrisk bue, der er helt rund og næsten lukket, og derefter udflade den betydeligt, påføres det færdige aggregat 70 et betydeligt, tilsigtet træk, således at sædet 35 giver en fjedrende fornemmelse, der hovedsagelig virker, som om det var en stor pude i stedet for simpelthen et aggregat af tynde fjedre. Den nøjagtige størrel- 145406 6 se af pilhøjden h eller af krumningen, afhænger naturligvis noget af smag, men almindeligvis vil der være en maksimal pilhøjde på ca. 25 mm i et ca. 400 mm bredt sædeaggregat 70, og forholdet er sædvanligvis bedst be-5 stemt som værende en pilhøjde h på 1/64 - 1/16 af spændvidden.This flattening of a round assembly is an important feature of the invention. By initially shaping the assembly 70 as a cylindrical arc which is completely round and almost closed, and then flattening it considerably, the finished assembly 70 is applied a considerable, deliberate pull so that the seat 35 gives a resilient feeling which is substantially seems like it was a big pillow instead of simply an aggregate of thin springs. The exact size of the arrow height h or of the curvature, of course, depends somewhat on taste, but generally there will be a maximum arrow height of approx. 25 mm in an approx. 400 mm wide seat assembly 70, and the ratio is usually best determined to be an arrow height h of 1/64 - 1/16 of the span.
Størrelsen af den kraft, som er nødvendig til at udflade et sæde i en størrelse til en typisk spisestuestol, er ligeledes vigtig. Til brug for opfin-10 delsen er det konstateret, at en samling af fjedre i et aggregat 70, som kræver en kraft på 150-300 kg til at flade det ud, giver et sæde med rigtigt træk, fortrinsvis omkring 225 kg. Dette er den kraft, som udøves for at trække de to ender 72 og 73 fra hinanden, så 15 at de kan komme i en passende afstand til at passe på stolesteldelene 67 og 68.The magnitude of the force required to flatten a seat one size for a typical dining chair is equally important. For use in the invention, it has been found that a collection of springs in a unit 70, which requires a force of 150-300 kg to flatten it, provides a seat with proper traction, preferably about 225 kg. This is the force exerted to pull the two ends 72 and 73 apart so that they can come at a suitable distance to fit the chair frame portions 67 and 68.
Til stoleryggen anvendes noget forskellige regler, og det skal bemærkes, at i stolen i fig. 1, som i de fleste af den slags stole, vender ryggens bue 20 bagud.Somewhat different rules are used for the chair back, and it should be noted that in the chair in fig. 1, as in most such chairs, the arch 20 of the back faces backwards.
Både i sædet og i ryggen er trådenes indadgående træk fra udfladningen også en af de hovedkræfter, som holder trådene på plads.Both in the seat and in the back, the inward pull of the threads from the flattening is also one of the main forces that hold the threads in place.
Plastbelægningen 79 kan vælges fra for-25 skellige typer plast, f.eks. polyvinylchlorid, poly-vinylacetat eller blandinger af disse, andre vinylkombinationer, polyethylen, butadien, acrylelastomere etc. Materialet kan være transparent eller kan være uigennemsigtigt og bibringe aggregatet sin egen farve.The plastic coating 79 can be selected from different types of plastic, e.g. polyvinyl chloride, poly-vinyl acetate or mixtures thereof, other vinyl combinations, polyethylene, butadiene, acrylic elastomers, etc. The material may be transparent or may be opaque and impart its own color to the unit.
30 Belægningen kan indeholde farvestof eller pigment,· som giver en ønsket farve og fuldstændig forhindrer synet af selve trådene 76 og giver indtryk af at udgøre det virkelige sædemateriale. Plastbelægningen 79 kan eventuelt være halvtransparent.The coating may contain dye or pigment, which gives a desired color and completely prevents the sight of the threads 76 themselves and gives the impression of constituting the actual seat material. The plastic coating 79 may optionally be semi-transparent.
35 Det skal bemærkes, at ifølge opfindelsen er plasten begrænset til aggregatet 70 eller 70A og 145406 7 anvendes ikke til stolestellet, således at stolestellet kan have en hvilken som helst ønsket overflade eller behandling uden indflydelse fra plastbelægningen.It should be noted that according to the invention the plastic is limited to the assembly 70 or 70A and is not used for the chair frame, so that the chair frame can have any desired surface or treatment without influence from the plastic coating.
De bugtede tråde 76 er fortrinsvis ikke 5 svejset sammen på de Steders hvor de tangerer hinanden, men holdes kun sammen ved hjælp af plastbelægningen 79, idet trådene 76 enten lige berører hinanden eller endog ligger lidt på afstand fra, men dog tæt ved hinanden. Det samme gør sig gældende ved forbindelsen 10 mellem trådene 76 og de bueformede sidestykker 74 og 75 på rammen 71.The curved wires 76 are preferably not welded together at the points where they tangential to each other, but are only held together by means of the plastic coating 79, the wires 76 either just touching each other or even being slightly spaced from, but still close to each other. The same applies to the connection 10 between the wires 76 and the arcuate side pieces 74 and 75 on the frame 71.
En vigtig egenskab ved plastbelægningen 79 er, at der kan opnås en dobbeltetrækvirkning, idet fjedrene 76 strækker sig ikke blot på kendt måde for 15 spændte fjedre, men også plastbelægningea 79 mellem de nærliggende fjedre 76 strækkes, og denne dobbelte strækvirkning giver sædet et udstrakt elasti-citetsområde. Hvis plastbelægningen 79 er for hård, kan der praktisk talt ikke fås en sådan strækning, og 20 hvis plastibelægningen 79 er for blød, vil den have for stor eftergivenhed, så at selve fjedrene 76 ikke udnyttes rigtigt, og aggregatet 70 kan endog rives itu efter kort tids brug. Ved at holde Shoredurometer-værdien for plastbelægningen inden for kritiske værdi-25 er, bliver virkningen rigtig med tilstrækkelig stivhed, så at fjedrene 76 udnyttes og holdes adskilt med tilstrækkelig elastiqitet, så at det hele ikke simpelthen indesluttes i en stiv belægning. Det er konstateret,-. at durometerværdiområdet, som er nødvendigt for at opnå 30 denne særdeles vigtige virkning, ligger fra ca. 45 - ca.An important property of the plastic coating 79 is that a double pulling effect can be obtained, the springs 76 extending not only in a known manner for tensioned springs, but also the plastic coating 79 between the adjacent springs 76 is stretched, and this double stretching effect gives the seat an extended elastic site area. If the plastic coating 79 is too hard, practically no such stretch can be obtained, and if the plastic coating 79 is too soft, it will have too much resilience so that the springs 76 themselves are not used properly and the assembly 70 can even be torn after short-term use. By keeping the Shoredurometer value of the plastic coating within critical values, the effect becomes real with sufficient rigidity so that the springs 76 are utilized and kept separate with sufficient elasticity so that the whole is not simply enclosed in a rigid coating. It has been established,. that the durometer value range required to achieve this extremely important effect is from approx. 45 - ca.
90 Shore A-durometerværdi med en foretrukket værdi på ca. 75.90 Shore A durometer value with a preferred value of approx. 75.
I fig. 6 og 7 er vist en sammenfoldelig stol 200 med et sæde 201 og en ryg 202, som kan fremstil-35 les af aggregaterne 70 og 70A under anvendelse af principperne ifølge qpfindelsen. Denne sammenfoldelige 145406 8 stol 200 har to sidesteldele 203, som bærer sædet 201, to bagben 204, som udgår fra stolen 200's forkant, og to kombinerede forben og rygsteldele 205, som bærer ryggen 202.In FIG. 6 and 7 show a folding chair 200 with a seat 201 and a back 202, which can be manufactured by the assemblies 70 and 70A using the principles of the invention. This collapsible chair 200 has two side frame members 203 which support the seat 201, two rear legs 204 which extend from the front edge of the chair 200, and two combined front legs and back frame members 205 which support the back 202.
5 Fig. 6-8 viser et væsentligt træk ved opfindelsen. Sædet 201 er hvælvet opad og ryggen 202 er hvælvet bagud, således at sædet 201, når stolen 200 er klappet sammen, kan være beliggende inden i ryggen 202, som vist i fig. 7. Dette muliggør en 10 meget kompakt sammenklapning af stolen 200, således at tykkelsen af stolen i en stak med sådanne sammenklappede stole ikke behøver at være større end stellets tykkelse.FIG. 6-8 show an essential feature of the invention. The seat 201 is arched upwards and the back 202 is arched backwards, so that the seat 201, when the chair 200 is folded, can be located inside the back 202, as shown in fig. 7. This enables a very compact folding of the chair 200, so that the thickness of the chair in a stack with such folded chairs does not have to be greater than the thickness of the frame.
Denne egenskab af kompakt stabelmulighed 15 er også anvendelig i en ikke sammenfoldelig, men kompakt stablelig stol, således at sæder ligger kompakt over sæder, og rygge ligger kompakt i rygge.This feature of compact stacking option 15 is also applicable in a non-collapsible but compact stackable chair so that seats lie compactly over seats and backs lie compactly in backs.
Nogle af den sammenklappelige stols egenskaber er også vist i det skematiske billede i fig. 8.Some of the properties of the folding chair are also shown in the schematic view in fig. 8.
20 Dette viser, at sædet 201 kan bue mindre end ryggen 202, og i de fleste tilfælde giver dette en mere behagelig stol 200, end hvis de var buede kun for at passe ind i hinanden. Ryggens konkavitet skal være lig med eller større end sædets. Med andre ord krumningsradien 25 af sædet 201 er længere end krumningsradien af ryggen 202. Ryggen 202 kan variere fra at have en radius, der er lig med sædet 201's radius, til en radius, der ikke er mindre end halvdelen af sædet 201's radius, for at sikre både komfort og rigtig sam-30 menfoldning. Naturligvis kan stakningen, hvis krumningerne er forskellige, blive noget mindre kompakt, men dette er en ulempe, som skal betragtes i forhold til den anden ulempe, ved at sædet og ryggen er ukomfortabelt at sidde på. I fig. 8 er vist et andet specifikt 35 træk ifølge opfindelsen. Sædet 201 har en pilhøjde mellem 6 og 25 mm. Når sædet 201 er foldet ind i20 This shows that the seat 201 can bend less than the back 202, and in most cases this provides a more comfortable chair 200 than if they were curved only to fit into each other. The concavity of the backrest must be equal to or greater than that of the seat. In other words, the radius of curvature 25 of the seat 201 is longer than the radius of curvature of the backrest 202. The backrest 202 may vary from having a radius equal to the radius of the seat 201 to a radius not less than half the radius of the seat 201, for to ensure both comfort and proper folding. Of course, if the curvatures are different, the stacking can be somewhat less compact, but this is a disadvantage that must be considered in relation to the other disadvantage, in that the seat and back are uncomfortable to sit on. In FIG. 8 shows another specific feature according to the invention. The seat 201 has an arrow height between 6 and 25 mm. When the seat 201 is folded into
