The present invention relates to an arrangement in a chair, especially for regulating the level of the seat, etc., comprising a rack or carrier frame (3) extending upwardly from a base (2), on which carrier frame for example a seat member (4) is removably attached, by detachable holding means (6a, 6b) for in detached position allowing sliding along said frame (3) for affixing at various levels, and for the purpose of providing an arrangement involving both simplified regulation of chair member level, as well as variation in the appearance of the chair, its field of use and mobility; it is according to the invention suggested that said carrier frame or carrier rack (3; 103; 203; 403) comprises at least one pair or set of substantially parallel elongated means (3a, 3b; 103a, 103b; 203a, 203b, 203c; 303a, 303b; 403a, 403b) having at least an intermediate slot (5; 105; 205a, 205b; 305; 405), and that in the area of said slot there are provided chair member carrying holding means (6a, 6b; 106a, 106b; 206; 306a, 306b; 406a, 406b), which holding means comprise friction elements (7x, 7y, 7z; 107x, 107y, 107z; 207w, 207x, 207y, 207z) which in a first chair member carrying position (Fig. 3) will induce a locking effect against the rod-shaped means, and which in a second released position of said chair member carrying means (Fig. 4) will be released from its locking effect against said elongated means for thereby allowing a displacement of said chair member carrying means to various level positions.
La présente invention concerne une chaise, en particulier pour ajuster le niveau du siège, etc., comprenant un bâti ou un cadre de support (3) s'étendant verticalement depuis une base (2). Sur ce cadre de support, il y a par exemple un siège (4) fixé de manière amovible, par un moyen de retenue amovible (6a, 6b) conçu pour permettre, dans la position détachée, un glissement le long du cadre (3) pour une fixation à différents niveaux. Le système ainsi obtenu permet d'ajuster simplement le niveau de la chaise, ainsi que de modifier l'aspect de la chaise, son domaine d'utilisation et sa mobilité. Selon l'invention, le cadre de support ou bâti (3; 103; 203; 403) comprend au moins une paire ou au moins un jeu de moyens allongés sensiblement parallèles (3a, 3b; 103a, 103b; 203a, 203b, 203c; 303a, 303b; 403a, 403b) ayant au moins une fente intermédiaire (5; 105; 205a, 205b; 305; 405). Des supports (6a, 6b; 106a, 106b; 206; 306a, 306b; 406a, 406b) de la chaise sont prévus dans la zone de ladite fente, lesquels supports comprennent des éléments à friction (7x, 7y, 7z; 107x, 107y, 107z; 207w, 207x, 207y, 207z) qui, dans une première position de support de la chaise, vont assurer un effet de verrouillage contre les tiges et qui, dans une seconde position de libération du support de la chaise, seront libérés de leur position de verrouillage contre les tiges pour permettre un déplacement des support de la chaise à différents niveaux.
