Claims (1)

<Desc/Clms Page number 1> <Desc / Clms Page number 1> L'invention est relative à un siège à quatre pieds, muni d'un dossier, dans lequel le cadre de l'assise, le cadre du dossier et les deux pieds avant du siège forment un ensemble rigide. The invention relates to a four-legged seat, provided with a backrest, in which the seat frame, the backrest frame and the two front legs of the seat form a rigid assembly. Le siège, établi conformément à l'invention, est caractérisé en ce que les pieds arrière, reliés entre eux par une entretoise, peuvent pivoter au- tour d'un axe transversal et être immobilisés dans plusieurs positions inclinées différenteso De cette manière, il est possible de transformer le .siège ayant la forme d'une chaise ordinaire en un siège de repos incliné vers l'arrière, Le dessin ci-annexé montre, titre d'exemple, un mode de réalisation de l'invention* Les figo 1 et 2 montrent, en coupe verticale, le siège dans deux po- sitions différentes. The seat, established according to the invention, is characterized in that the rear legs, interconnected by a spacer, can pivot around a transverse axis and be immobilized in several different inclined positions. In this way, it is possible to transform the seat having the shape of an ordinary chair into a resting seat inclined backwards, The accompanying drawing shows, by way of example, one embodiment of the invention * Figures 1 and 2 show, in vertical section, the seat in two different positions. La fige 3 montre, à plus grande échelle, une partie du siège de la fig. 1, afin de montrer plus clairement certains détails de celui-ci. Figure 3 shows, on a larger scale, part of the seat of FIG. 1, in order to show some details of it more clearly. Le siège à quatre pieds muni d'un dossier comporte , comme visible sur les fige 1 et 2, un châssis a qui forme en même temps le cadre de l'assise et celui du dossier. Au cadre de l'assise sont fixés les deux pieds avant b, de sorte que les cadres susdits et les pieds avant b forment un ensemble rigide. The four-legged seat provided with a backrest comprises, as can be seen in figs 1 and 2, a frame a which forms at the same time the frame of the seat and that of the backrest. The two front legs b are fixed to the frame of the seat, so that the aforesaid frames and the front legs b form a rigid unit. Les deux pieds arrière c sont reliés entre eux par une entretoise ai et articu- lés au cadre de l'assise de manière à pouvoir pivoter autour d'un axe transver- sale A cet effet, on monte sur chacun des deux pieds arrière des ferrures. consti- tuées par deux plaques de butéeUne plaque d (figo 3) est fixée par des vis sur la face interne du côté correspondant du cadre de l'assiseo Cette plaque de butée d comporte, le long de son pourtour, des saillies dl, en forme de dents, rabattues vers l'intérieur, ainsi que des rebords latéraux d2 , rabattus d'une manière analogue, qui forment des butées limitant un mouvements L'autre plaque de butée a une section transversale en forme de U et est fixée par des vis sur la face externe de la partie terminale supérieure du pied arrière correspondant c. The two rear legs c are connected to each other by a spacer ai and articulated to the frame of the seat so as to be able to pivot about a transverse axis. For this purpose, fittings are fitted on each of the two rear legs. . consisting of two stop plates A plate d (figo 3) is fixed by screws on the internal face of the corresponding side of the seat frame o This stop plate d has, along its periphery, projections dl, in tooth-shaped, folded inwards, as well as lateral flanges d2, folded down in a similar manner, which form stops limiting movement The other stop plate has a U-shaped cross section and is fixed by means of screws on the outer face of the upper end part of the corresponding rear foot c. Cette plaque e comporte une fente longitudinale el dans laquelle est engagé un ergot.! fixé sur l'autre plaque de butée de Entre les deux plaques e et d exis- te, par conséquent, une liaison par fente et ergot qui permet, à proximité de la fente el, un coulissement de la plaque e par rapport à la plaque do A l'extré- mité externe de la plaque!. sont établies deux cames e2 qui sont symétriques par rapport à l'axe longitudinal de cette plaque e et qui peuvent pénétrer entre les dents dl de la plaque de butée d. This plate e has a longitudinal slot el in which a lug is engaged.! fixed on the other stop plate of Between the two plates e and d exists, consequently, a connection by slot and lug which allows, near the slot el, a sliding of the plate e relative to the plate do At the outer end of the plate !. two cams e2 are established which are symmetrical with respect to the longitudinal axis of this plate e and which can penetrate between the teeth d1 of the stop plate d. Un rebord, qui se trouve entre ces deux cames, est rabattu vers l'intérieur et forme une butée g entre laquelle et l'er- got f est intercalé un ressort de compression h qui tend à refouler la plaque e vers l'extérieur, pour assurer ainsi le contact entre les cames e2/et les dents 'il . A rim, which is located between these two cams, is folded inwards and forms a stop g between which and the ertotle f is interposed a compression spring h which tends to force the plate e outwards, thus ensuring contact between the cams e2 / and the teeth 'il. Pour amener les pieds arrière c depuis leur position de soutien montrée sur la figo 1 à la position montrée sur la figo 2, on penche le siège un peu en avant, on empoigne l'entretoise c1 et on dégage, par traction, les cames e2 , contre l'action des ressorts h hors de la partie dentée de la plaque de butée e. Les pieds arrière c peuvent alors pivoter autour de l'axe f vers l'ar- rièreo Quand on fait cesser .l'effet exercé sur l'entretoise c1, les cames e2 pénètrent à nouveau entre les dents de la plaque de butée par l'effet des ressorts de com- pression'? RESUME. **ATTENTION** fin du champ CLMS peut contenir debut de DESC **. To bring the rear legs c from their supporting position shown in fig 1 to the position shown in fig 2, tilt the seat a little forward, grasp the spacer c1 and pull out the cams e2 , against the action of the springs h outside the toothed part of the stop plate e. The rear feet c can then pivot around the axis f towards the rear o When the effect exerted on the spacer c1 is stopped, the cams e2 again enter between the teeth of the stop plate through the 'effect of compression springs'? ABSTRACT. ** CAUTION ** end of field CLMS may contain start of DESC **.
