Abstract

En stol där ryggstödet (B) kan ställas i olika lutningar tack vare infästning i stolens sidor med tvä pluggar (C) och tvä sidostöd (1) där de bakre delarna bildar ciikelbågar (2) med flera urtag för ryggstöttets nedre tvärslå (4). Genom en slits (6) i stolens sidosargar bildas en fjäder (7) som lyfts när man väljer lutning och häller ryggstödet (B) i valt läge.A chair in which the backrest (B) can be set at different angles thanks to attachment to the sides of the chair with two plugs (C) and two side supports (1) where the rear parts form circular arches (2) with several recesses for the lower crossbar of the backrest (4). Through a slot (6) in the side edges of the chair, a spring (7) is formed, which is lifted when the inclination is selected and tilts the backrest (B) into the selected position.

Description

Stol med ställbart ryggstöd Tekniskt område Den här uppfinningen avser en stol där ryggstödet kan ställas i olika lägen och där lägena låses av fjädrar i sidosargarna. Chair with adjustable backrest Technical area This invention relates to a chair where the backrest can be set in different positions and where the positions are locked by springs in the side frames.

Teknikens ståndpunkt De flesta stolar har fix form och saknar möjlighet att ändra sittställning. Detta kan vara ett problem då våra kroppar uppvisar stor variationsrikedom. The state of the technology Most chairs have a fixed shape and lack the possibility to change the sitting position. This can be a problem as our bodies show great diversity.

Problemlösning Föreliggande uppfinning löser problemet med de fixa stolarna genom de i efterföljande patentkrav angivna särdragen. Den förbättrar också möjligheterna att renovera en trasig stol då den är enkel att demontera i flera delar. Problem solution The present invention solves the problem with the fixed chairs through the features specified in the subsequent patent claims. It also improves the possibilities of renovating a broken chair as it is easy to dismantle in several parts.

F igurförteckning Figur (1) visar stolen från sidan, de streckade linjerna visar läget vid omställning av ryggstödet. Figur (2) visar stolen framifrån Detaljbeskrivning av uppfinningen Stolen består av en basdel (A), uppbyggd av fyra ben, förbundna med fyra sargdelar - främre, bakre och två sidosargar, två nedre sido- och ett bakre benstöd (9). List of figures Figure (1) shows the chair from the side, the dashed lines show the position when adjusting the backrest. Figure (2) shows the chair from the front Detailed description of the invention The chair consists of a base part (A), made up of four legs, connected by four side parts - front, rear and two side sides, two lower side and a rear leg support (9).

Vidare ett ställbart ryggstöd (B), två förbindningspluggar (C) och en sits (D). Stolens nedre sidostöd (1), är utformade så att de baktill har formen av cirkelbågar (2), med urtag vända mot cirkelns vridcentrum (3). Det Ställbara ryggstödet (B) avslutas nertill med en tvärslå (4), utformad att passa i cirkelbågarnas urtag. Furthermore, an adjustable backrest (B), two connection plugs (C) and a seat (D). The chair's lower side supports (1) are designed so that at the back they have the shape of circular arcs (2), with recesses facing the center of rotation of the circle (3). The adjustable backrest (B) ends at the bottom with a cross bar (4), designed to fit into the recesses of the circular arches.

Ryggstödet fästs med två pluggar (C), genom hålen, som är cirkelns vridcentrum, längst baki de båda sidosargama (5). The backrest is attached with two plugs (C), through the holes, which are the center of rotation of the circle, at the back of the two side frames (5).

En horisontell slits (6), upptill i sidosargarna gör att den övre smalare delen, bildar en fjäder (7), som lyfts av ryggstödets pluggar vid byte av ryggstödets läge och håller ryggstödet på plats i valt urtag i cirkelbågen. Framför slitsen, som avslutas 5 cm från infästrringen i frambenet, sitter en skruv (8), vertikalt genom sidosargen för att hindra att fjädern fläks upp.A horizontal slot (6), at the top of the side skirts, causes the upper narrower part to form a spring (7), which is lifted by the backrest's plugs when the backrest's position is changed and holds the backrest in place in the selected recess in the circular arch. In front of the slit, which ends 5 cm from the attachment in the front leg, there is a screw (8), vertically through the side edge to prevent the spring from flaking up.

Claims (1)

1.En f yrbent stol, kännetecknad av att den har ett ryggstöd (B) som kan ställas i olika lägen. Ryggstödet (B) är upphängt med två pluggar (C) genom hål (3) baktill i två sidosargar (5). Dessa hål (3) utgör vridcentrum av en tänkt cirkel vars cirkelbåge (2) återfinns i bakre delen av två nedre sidostöd (1) och har urtag för att ta emot en tvärslå (4) som avslutar ryggstödet nertill och låser ryggstödet (B) i önskat läge. För att hålla ryggstödet (B) på plats i önskat urtag finns en fjäder (7) anordnad på båda sidosargarna (5) som är anordnad med en horisontell slits (6) genom de båda sidosargarna (5), där en övre smalare del bildar fjädern (7), vilken avslutas 5 cm bakom infästningen i frarnbenet. Ryggstödet (B) är anordnat att lyftas i en riktning uppåt mot fjäderns (7) kraft för att sedan vridas kring vridcentrumet till önskat läge. En vertikal skruv (8) genom sidosargen (5) hindrar slitsen från att fortskrida genom hela sidosargens (5) längd och förhindrar därför att fjädern (7) fläks upp.1. A four-legged chair, characterized by the fact that it has a backrest (B) that can be set in different positions. The backrest (B) is suspended with two plugs (C) through holes (3) at the back in two side frames (5). These holes (3) form the center of rotation of an imaginary circle whose circular arc (2) is found in the rear part of two lower side supports (1) and have recesses to receive a cross bar (4) which ends the backrest at the bottom and locks the backrest (B) in desired mode. To hold the backrest (B) in place in the desired recess, there is a spring (7) arranged on both side skirts (5) which is arranged with a horizontal slot (6) through the two side skirts (5), where an upper narrower part forms the spring (7), which ends 5 cm behind the attachment in the frontal bone. The backrest (B) is arranged to be lifted in an upward direction against the force of the spring (7) and then rotated around the center of rotation to the desired position. A vertical screw (8) through the side bar (5) prevents the slot from progressing through the entire length of the side bar (5) and therefore prevents the spring (7) from flaring up.
