Ramkonstruktion for en fållbar stol -Taitettavan tuolin runkorakenneFrame construction for a folding chair - Taitettavan tuolin runkorakenne
Denna uppfinning avser en ramkonstruktion får en fållbar 5 stol omfattende en sittdel och en till dennas bakre ånde svångbart lagrad ryggstodsdel, varvid roggstbdsdelen dessutom år svångbart lagrad vid stolens vardera armstods-del på avstånd från ryggstodets lagringspunkt med sittde-len, vilken sittdel invid respektive armstddsdel uppvisar 10 en framåt snett uppåt riktad glid, vilken glid år anordnade att samverka med en vid respektive armstddsdel vridbart lagrad lås- och/eller lagerdosa.This invention relates to a frame structure provided with a foldable chair comprising a seat part and a backrest pivotally supported backrest portion, the ridge support portion being additionally pivotally stored at each armrest portion of the chair at a distance from the backrest storage point with the seat portion, which seat portion adjacent the respective armrest 10 has a forward obliquely upwardly directed slide, which slide is arranged to cooperate with a locking and / or bearing box rotatable at each armrest part.
I tidigare kånda Tårnkonstruktioner av ovannåmnda typ har de 15 vardera armstodsdelarna varit uppbyggda av en av flatjårn svetsad huvudsakligen trapetsformig ramkonstruktion vid vilken ett i trå framstållt egentligt armstdd år fastskru-vat. Dessutom år de bågge armstddsdelarna sammanbundna medelst ett tvårgående metallstag. En dylik ramkonstruktion 20 erhåller en relativt hdr vikt samtidigt som den fordrar ett ytterst arbetsdrygt framstållningsforfarande.In previously known Tower structures of the above-mentioned type, each of the armrests has been made up of a mainly trapezoidal frame structure welded by flat iron to which an actual arm-supported year is screwed. In addition, the arched armrests are joined together by a two-way metal rod. Such a frame structure 20 obtains a relatively heavy weight while requiring an extremely laborious manufacturing process.
Foreliggande uppfinning har till uppgift att åstadkomma en lått och enkel ramkonstruktion som går snabbt och enkelt 25 att framstålla och omfattar ett betydligt reducerat antal ' ‘ komponenter.The object of the present invention is to provide a light and simple frame construction which is quick and easy to manufacture and comprises a significantly reduced number of components.
Detta uppnås med en ramkonstruktion som kånnetecknas av att armstodsdelens stomme utgdrs av en huvudsakligen Z-formigt 30 bockad tunn metallplåt, varvid metallplåtens 5vre horison-. tella skånkel utgdr sjålva armstddet och dess nedre ho- risontella skånkel utg6r fåstplatta f6r stolens stativ eller gunga.This is achieved with a frame structure which is characterized in that the body of the armrest part is made up of a substantially Z-shaped curved thin metal plate, the horizontal of the metal plate 5 being. counting shank consists of the actual armrest and its lower horizontal shank is the fixing plate for the chair's stand or swing.
35 Genom Tårnkonstruktionen enligt foreliggende ansokan elimineres en mångd svetsningsarbete vilket avsevårt reducerer framstållningskostnaderna. Uppfinningens bvriga kånnetecken 2 91707 framgår ur de bifogade osjålvståndiga patentkraven 2-5.35 The tower construction according to the present application eliminates a lot of welding work which considerably reduces the production costs. The other characteristic features of the invention 2 91707 are apparent from the attached non-dependent claims 2-5.
I det f01jånde skall uppfinningen nårmare beskrivas under 5 hanvisning till den bifogade ritningen, i vilken fig. 1 visar ett exempel på en ramkonstruktion enligt uppfinningen sett från sidan, 10 fig. 2 visar Tårnkonstruktioner sedd uppifrån och fig. 3 visar ramkostruktionen sedd fraraifrån.In the foregoing, the invention will be described in more detail with reference to the accompanying drawing, in which Fig. 1 shows an example of a frame construction according to the invention seen from the side, Fig. 2 shows tower structures seen from above and Fig. 3 shows the frame construction seen from a distance.

Ryggstddsdelen 2 år dessutom svångbart lagrad vid stolens bågge armstOdsdelar 3, fore-trådesvis kring en horisonten axel 4 i respektive arm-stodsdels 3 bakre Ovre hOrn, på avstånd från ryggstOdets 2 20 lagringspunkt 5 med sittdelen 1. Sittdelen 1 år å sin sida glidbart lagrad till stolens bågge armstOdsdelar 3 medelst ett par vid sittdelens 1 respektive sida stadigt fåst framåt snett uppåt riktad glid 6, vilken glid 6 samverkar med en vid respektive armstOdsdel 3 vridbart lagrad lås-25 och/eller lagerdosa 7. Vid påverkan av lås- och/eller lagerdosans 7 låsorgan år gliden 6 anordnad att glida utmed lås- och/eller lagerdosan 7. På ritningen år stolen visad i upprått låge. Då man Onskar åndra stolens låge påverkas lås- och/eller lagerdosans 7 låsorgan via ett på armstods-30 delen 3 anordnat manOverorgan så att gliden 6 frigOrs och kan glida utmed lås- och/eller lagerdosan 7. Då man sittan-de i stolen pressar ryggstOdsdelens 2 Ovre parti lått bakåt svånger ryddstOdet 2 kring axeln 4 i armstOdsdelens 3 ovre bakre hOrn och pressar samtidigt framåt sittdelen 1, vilken 35 i stod av glidparet 6 fOrskjts framåt och snett uppåt.The present tower construction for a foldable chair 15 comprises a seat part 1 and a backrest pivotally supported backrest portion 2 to its rear breath. The backrest part 2 is also pivotally stored at the arched armrest portions 3, preferably around a horizontal axis 4 in each arm. base part 3 rear upper corner, at a distance from the backrest 2 of the backrest 2 with the seat part 1. The seat part 1 is slidably mounted to the arched armrest parts 3 by means of a pair at the respective side of the seat part 1 steadily obtained forwardly inclined upwardly sliding 6, which slide 6 cooperates with a locking and / or bearing box rotatably stored at each armrest part 3. In the actuation of the locking means and / or the bearing box 7, the slide 6 is arranged to slide along the locking and / or the bearing box 7. In the drawing, the chair is shown. in upright position. When Onskar breathes the seat of the chair, the locking means of the locking and / or bearing box 7 is actuated via a man-upper member arranged on the armrest part 3 so that the slide 6 is released and can slide along the locking and / or bearing box 7. When sitting in the chair presses The upper portion of the backrest 2 lowered backwards, the clearance 2 rotates about the axis 4 in the upper rear corner of the armrest 3 and at the same time pushes forward the seat portion 1, which in the support of the sliding pair 6 is moved forward and obliquely upwards.
En dylik upphångning av ryggstOdsdel 2 och sittdel 1 har en 1; 91707 3 mycket stabiliserende inverkan på stolens sjålva Tårnkonstruktion, vilket gett idén till fOreliggande uppfinning att fOrenkla uppbyggnaden av stolens Tårnkonstruktion. Det ta har åstadkomraits genom att framstålla hela armstOdsdelens 5 2 stomme av en huvudsakligen Z-formigt bockad relativt tunn metallplåt. Erforderlig stadga i konstruktionen uppnås genom den ovan beskrivna upphångningen av sittdel 1 och ryggstbdsdel 2. ArmstOdsdelens 2 Ovre horisontella skånkel 9, vilken år riktad utåt från stolen utgOr stolens armstOd, 10 medan den nedre horisontella skånkeln 10 utgOr fåstplatta for stolens stativ 11 eller gunga. FOr åndamålet år fåsthål upptagna i nåmnda nedre skånkel 10. Lås- och/eller lager-dosan 7 år vridbart lagrat fåst vid det vertikala partiet av armstodesdelen 3, låmpligen medelst en fåstplatta 12, 15 vilket ytterligare Okar stabiliteten.Such a suspension of backrest part 2 and seat part 1 has a 1; 91707 3 a very stabilizing effect on the chair's actual Tower construction, which gave the idea of the present invention to simplify the structure of the chair's Tower construction. This take has been achieved by producing the body of the entire armrest portion 2 of a substantially Z-shaped bent relatively thin metal sheet. The required stature in the construction is achieved by the above-described suspension of seat part 1 and backrest part 2. Upper horizontal shank 9 of armrest part 2, which is projected outwardly from the chair, is the armrest of the chair 10, while the lower horizontal shank 10 constitutes a fixed plate for the chair stand 11. For the purpose, attachment holes are provided in said lower shank 10. The locking and / or bearing box 7 is rotatably stored at the vertical portion of the armrest portion 3, suitably by means of a fixing plate 12, which further increases stability.
For att erhålla mOjligast god stadga i de bockade metall-plåtarna kan man med fOrdel i området kring varje bookning pressa ett antal stabiliserande utbuktningar 13. I utfOran-20 det enligt ritningen uppvisar armstOdsdelen 3 fyra stycken utbuktningar 13 vid den Ovre bookningen och tre utbuktningar 13 vid den nedre bookningen.In order to obtain the best possible statute in the bent metal plates, a number of stabilizing bulges 13 can be pressed with advantage in the area around each booking. In the embodiment according to the drawing, the armrest portion 3 has four bulges 13 at the upper booking and three bulges 13 at the lower booking.
