Opfindelsen angår en stol, især spisebordsstol, som består af et par sidevanger; vandrette ben, som er forbundet med de nedre partier af sidevangerne og er indrettet til at understøtte disse; et rygstød, som forbinder sidevangernes øvre partier 5 med hinanden; en sædeplade og en fodplade, hvilke sidevanger på indersiden over en del af deres højde er forsynet med et antal vandret forløbende føringer, i hvilke kan indføres sidekanterne af sædepladen og fodpladen, og hvilke sidevanger strækker sig opad og bagud i forhold til lodret, og at de 10 vandrette ben strækker sig bagud i forhold til sidevangernes bagside.The invention relates to a chair, in particular a dining table chair, which consists of a pair of side wings; horizontal legs which are connected to the lower portions of the side wings and are adapted to support these; a backrest which connects the upper portions 5 of the laterals; a seat plate and a foot plate, said side rails on the inside of a portion of their height being provided with a number of horizontally extending guides, into which the side edges of the seat plate and the foot plate can be inserted, and said side rails extending upwards and rearwards relative to the vertical, and the 10 horizontal legs extend backwards relative to the back of the side wings.

Fra fransk patentskrift nr. 940.427 kendes en barnestol, som består af et par skrå sidevanger, som forneden går over i vand-15 rette ben og foroven bærer en sædeplade forsynet med et rygstød, som forbinder sidevangernes øvre partier med hinanden.From French Patent Specification No. 940,427 is known a child seat, which consists of a pair of oblique sidewalls, which go downwards into water-straight legs and at the top carries a seat plate provided with a backrest connecting the upper parts of the sidewalls.

De vandrette ben er forbundet med hinanden ved hjælp af et tværstykke. Lidt over midten er mellem sidevangerne anbragt en fodplade. Midt på sidevangerne findes hængsler, således at 20 stolen i udklappet tilstand kan anvendes som høj stol og i sammenklappet tilstand som lav stol, idet benene og den nedre halvdel af sidevangerne kan svinges ind under sædepladen med rygstødet. Sædepladen og fodpladen er fastgjort permanent til sidevangerne og kan derfor ikke flyttes i højden eller i dyb-25 den, hvorfor stolen kun kan bruges til små børn.The horizontal legs are connected to each other by means of a cross piece. A little above the middle is a footplate placed between the side wings. Hinges are located in the middle of the side rails so that the folded chair can be used as a high chair and in the folded state as a low chair, as the legs and the lower half of the side rails can be swung under the seat plate with the backrest. The seat plate and foot plate are permanently attached to the side wings and therefore cannot be moved to height or depth, which is why the chair can only be used for small children.

Formålet med opfindelsen er at anvise en stol af den ovenfor nævnte art, som har stor stivhed og let kan tilpasses til børn i forskellige aldre.The object of the invention is to provide a chair of the above-mentioned type which has a high stiffness and can easily be adapted for children of different ages.

Stolen ifølge opfindelsen er ejendommelig ved, at sidevangerne er indbyrdes forbundet ved hjælp af tværgående dele i forbindelse med fastspændingsorganer, f.eks. skruemøtri korganer, til fastspænding af sæde- og fodpladen i de valgte føringer på si-35 devangernes inderside, og at både sædepladen og fodpladen strækker sig fremad fra sidevangernes forside. Ved denne udformning tilvejebringes en stol med stor stivhed, hvor flyt- 2 DK 159367 B \ ning af sædepladen og fodpladen i indbyrdes højdeafstand eller i passende dybde, eventuelt ombytning af pladerne, kan ske på en hurtig og enkel måde uden behov for skrueforbindelse mellem den pågældende plade og sidevangerne, således at stolen let 5 kan tilpasses til børn i forskellige aldre. Desuden opnås en stol, som i brug er meget stabil. Selv når et barn sidder i stolen og sparker mod et tilhørende bord, skal der et meget kraftigt tryk mod bordet, før stolen vælter. Samtidigt tilvejebringes en stol, som er let at flytte.The chair according to the invention is characterized in that the side wings are interconnected by means of transverse parts in connection with clamping means, e.g. screw nuts for fastening the seat and foot plate in the selected guides on the inside of the si-35 vanes, and that both the seat plate and foot plate extend forward from the front of the side vanes. In this embodiment, a chair with high rigidity is provided in which the movement of the seat plate and the foot plate at mutual height or at a suitable depth, possibly changing the plates, can be done in a quick and simple manner without the need for screw connection between it. plate and the side wings so that the chair can easily be adapted for children of different ages. In addition, a chair is obtained which is very stable in use. Even when a child sits in the chair and kicks at an associated table, a very strong pressure must be pressed against the table before the chair is overturned. At the same time, a chair is provided which is easy to move.

Ifølge opfindelsen kan sædepladen og fodpladen have forskellig dybde for ved ombytning at kunne tjene som fodstøtte henholdsvis sæde. Herved opnås en komfortabel siddestilling for personer af forskellig højde, som sidder ved et bord med stan-15 dardhøjde. Små børn er nemlig i væsentlig grad afhængige af en god understøtningsflade for benene (den større fodplade anbragt nederst, fig. 2 og 3), medens voksne kan klare sig med en mindre understøtningsplade for benene (den mindre sædeplade anbragt nederst, fig. 4). Voksne er nemlig mere afhængige af 20 en stor sædeflade på grund af en større længde af overbenet, end hvad tilfældet er for børn.According to the invention, the seat plate and the foot plate may have different depth in order to be able to serve as footrests or seat, respectively, in exchange. This provides a comfortable sitting position for people of different heights sitting at a table with standard height. Namely, young children are substantially dependent on a good support surface for the legs (the larger foot plate placed at the bottom, Figs. 2 and 3), while adults can cope with a smaller support plate for the legs (the smaller seat plate placed at the bottom, Figure 4). . Adults are more dependent on a large seat surface due to a greater length of upper leg than is the case for children.

Endvidere kan ifølge opfindelsen sædepladen være i stand til at rage frem foran fodpladen, når sædepladen danner en fod-25 støtte. Herved opnås, at når en voksen sidder i stolen, vil den voksnes underben danne en omtrent ret vinkel med den voksnes overben, således at en korrekt siddestilling opnås.Furthermore, according to the invention, the seat plate may be able to project in front of the foot plate when the seat plate forms a foot support. This results in the fact that when an adult sits in the chair, the adult's lower leg will form at approximately the right angle with the adult's upper leg so that a correct sitting position is obtained.

Opfindelsen forklares nærmere under henvisning til tegningen, 30 hvor fig. 1 viser en udførelsesform for en stol ifølge opfindelsen set i perspektiv, og 35 fig. 2-5 stolen i forskellige tiIpasningssti11inger for børn i forskellige aldre.The invention is explained in more detail with reference to the drawing, in which fig. 1 is a perspective view of an embodiment of a chair according to the invention, and FIG. 2-5 chairs in various fitting positions for children of different ages.

Den i fig. 1 viste udførelsesform for en stol består af to sidevanger 1 med langstrakt rektangulært tværsnit. Sidevangerne 1 kan f.eks. være udformet af to solide planker af træmateriale, eller de kan være udformet af plast. Forneden går side-5 vangerne 1 over i vandrette ben 2, som hviler på gulvet. Foroven er sidevangerne 1 forbundet med et rygstød 3, på midten med et tværstag 4 og forneden med en tværplanke 5.The FIG. 1 embodiment of a chair consists of two side wings 1 of elongated rectangular cross section. The side vanes 1 can e.g. be made of two solid planks of wood material, or they may be made of plastic. Below, the side-5 racks 1 move into horizontal legs 2 which rest on the floor. At the top, the side wings 1 are connected to a backrest 3, in the middle with a transverse rod 4 and the bottom with a transverse plank 5.

I sidevangerne l's inderside er der over størstedelen af deres 10 højde udformet i hovedsagen vandrette føringer eller spor 10, således som dette tydeligt fremgår af fig. 1. Disse spor 10 er tilpasset til at kunne optage sidekanter 9 af en sædeplade 7 og en fodplade 6. Sædepladen 7 har en væsentlig mindre dybde end fodpladen 6.In the interior of the side rails 1, over most of their height 10, substantially horizontal guides or grooves 10 are formed, as can be clearly seen in FIG. 1. These grooves 10 are adapted to accommodate side edges 9 of a seat plate 7 and a foot plate 6. The seat plate 7 has a substantially less depth than the foot plate 6.

Som det fremgår af fig. 1 strækker sidevangerne 1 sig opad og bagud i forhold til lodret, og de vandrette ben 2 strækker sig bagud i forhold til sidevangerne l's bagside. Sædepladen 7 og fodpladen 6 strækker sig fremad fra sidevangerne l's forside.As shown in FIG. 1, the side wings 1 extend upwardly and rearwardly relative to the vertical, and the horizontal legs 2 extend rearwardly relative to the backside 1 of the side wings. Seat plate 7 and foot plate 6 extend forwardly from the front of side vanes 1.

2Ό Herved opnås en stol med stor stabilitet, dvs. som vanskeligt kan vælte, og som samtidigt er forholdsvis let at flytte.2Ό This results in a chair with great stability, ie. which can be easily overturned and which are at the same time relatively easy to move.

Ved at indsætte sædepladen 7 og fodpladen 6 i hensigtsmæssig indbyrdes afstand samt i ønsket højde i forhold til bordplade-25 højden, vil man få en stol, som giver tilfredsstillende understøtning. I fig. 2 vises således stolens tilpasning til et lille barn. Sædepladen 7 står her i et af de øverste spor 10, og fodpladen 6 er tilsvarende anbragt således, at barnet får en gunstig understøtning af sæde og fødder. I den viste udfø- 30 relsesform er stolen også udført med en strop eller bøjle 11, som hindrer barnet i at falde fremover. Stolen kan således anvendes til børn, som er meget små. 1 fig. 3 er stolen tilpasset til et noget større barn. Sæde- 35 pladen 7 og fodpladen 6 er da flyttet et stykke ned på side vangerne 1 for at give rigtig sædehøjde.By inserting the seat plate 7 and the foot plate 6 at a suitable distance from each other and at the desired height in relation to the table top height, a chair will be provided which provides satisfactory support. In FIG. 2, the adjustment of the chair to a small child is thus shown. The seat plate 7 stands here in one of the upper grooves 10, and the foot plate 6 is similarly arranged so that the child receives a favorable support of the seat and feet. In the embodiment shown, the chair is also provided with a strap or brace 11 which prevents the child from falling forward. The chair can thus be used for children who are very small. 1 FIG. 3, the chair is adapted for a somewhat larger child. The seat plate 7 and the foot plate 6 are then moved slightly down the side of the racks 1 to give proper seat height.

DK 159367 BDK 159367 B

4 I fig. 4 er stolen indrettet til et større barn. For at give rigtig sædehøjde og således god sædeunderstøtning er fodpladen 6 her flyttet op og anvendt som sædeplade, mens sædepladen 7 er flyttet ned og anvendt som fodplade.4 In FIG. 4, the chair is designed for a larger child. In order to provide proper seat height and thus good seat support, the foot plate 6 has here been moved up and used as a seat plate, while the seat plate 7 has been moved down and used as a foot plate.

5 I fig. 5 vises endelig stolen tilpasset til et stort barn eller en voksen. Sædepladen udgøres da igen af den noget dybere fodplade 6, medens fodpladen som sådan er sløjfet, idet personen, som sidde på stolen, kan anvende gulvet som fodunder-10 støtning.5 In FIG. 5 finally, the chair is adapted for a large child or an adult. The seat plate is then again constituted by the somewhat deeper foot plate 6, while the foot plate as such is loosened, the person sitting on the chair being able to use the floor as foot support.

□et vil umiddelbart forstås, at den viste udførelsesform blot illustrerer, hvorledes opfindelsen kan bringes til udførelse.It will be understood immediately that the embodiment shown merely illustrates how the invention may be carried out.

15 Sidevangerne såvel som disses forbindelsesdele kan således æn dres på mange måder. I den viste udførelsesform sker forbindelsen mellem sidevangerne 1 som nævnt ved hjælp af delene 3, 4 og 5. Disse er anbragt i forbindelse med skrue-møtrikorga-ner, som bevirker, at man ved at skrue møtrikkerne 8 til på 20 ydersiden af sidevangerne 1 kan trække disse mod hinanden og dermed fastklemme og sikkert fastlåse sæde- og fodpladen i de ønskede stillinger, hvori de er blevet anbragt. Imidlertid kan der naturligvis også tænkes anvendt andre fastholdelses- eller fastlåsningsorganer. Det aller enkleste vil i øvrigt være, at 25 sæde- og fodpladen med deres kanter anbringes i sporene 10 med en sådan prespasning, at de fastholdes ved friktion. Da imidlertid en sådan løsning vil være utilfredsstillende efter en vis tid, idet spillerum vil opstå ved slitage, bør denne løsning eventuelt kombineres med elastiske organer, som er ind-30 lagt i de samvirkende dele eller andre låseorganer. Ved låsningen ifølge den viste udførelsesform opnår man også den fordel, at de øvre skrue-møtrikorganer 8 kan tjene til befæsti-gelse af stroppen eller bøjlen 11, når stolen anvendes til meget små børn.15 The side vanes as well as their connecting parts can thus be changed in many ways. In the illustrated embodiment, the connection between the side vanes 1 as mentioned is made by means of the parts 3, 4 and 5. These are arranged in connection with screw-nut members, which by screwing the nuts 8 to 20 on the outside of the side vanes 1 can pull these against each other, thereby clamping and securely locking the seat and foot plate in the desired positions in which they have been placed. However, of course, other retaining or locking means may also be used. Incidentally, the simplest will be that the seat and foot plate, with their edges, are placed in the grooves 10 with such a press fit that they are retained by friction. However, since such a solution will be unsatisfactory after a certain period of time as clearance will result from wear and tear, this solution should optionally be combined with elastic means which are inserted into the cooperating members or other locking means. In the locking according to the embodiment shown, the advantage is also obtained that the upper screw-nut means 8 can serve to fasten the strap or brace 11 when the chair is used for very young children.
