Description

La présente invention concerne une armature, constituée d'éléments articulées, composée dtune telle manière et comportant un tel mouvement qu'elle est praticable comme construction de base et comme carcasse pour des éléments sur lesquels on peut être assis, analogue au principe des chaises avec dossier dont le siège et le dossier peuvent, l'un par rapport a' l'autre, changer de position. The present invention relates to a frame, consisting of articulated elements, composed in such a way and comprising such a movement that it is practicable as a basic construction and as a carcass for elements on which one can be seated, analogous to the principle of chairs with backrest whose seat and backrest can, relative to each other, change position.

On connait une chaise à quatre pieds suivant l'invention, enrégistrée en
France sous le numéro de brevet 85 14 707 à base d'une structure permettant deux positions d'utilisation; cependant cette construction présente plusieurs inconvér.iants, tels que:
La visibilité d'une construction compliquée en dessous du siège;
les mouvements inévitables des extrémités des pieds sur le sol pendant
le changement de position, exigeant des roulettes afin de réaliser un
mouvement assez souple;
l'endroit du point de suspension de l'élément "bascule" dans la plate
forme et non à la hauteur de l'articulation de la hanche, cause d'un
dépiacement désagréable entre le dos et le dossier pendant le mouvement
"change position".
We know a four-legged chair according to the invention, registered in
France under patent number 85 14 707 based on a structure allowing two positions of use; however, this construction has several disadvantages, such as:
The visibility of a complicated construction below the seat;
the inevitable movements of the extremities of the feet on the ground during
change of position, requiring casters in order to achieve a
fairly flexible movement;
the place of the point of suspension of the "rocking" element in the flat
shape and not at the level of the hip joint, cause of a
unpleasant tracking between the back and the backrest during the movement
"change position".

Les éléments composants pour la réalisation d'une armature selon la pré- sente invention sont: un élément "porteur" (1-2) de construction rigide et non déformable, composé d'une "plate-forme" d'environ 50 x50 ceAtimètres (2) en position horizontale ou à peu prés horizontale, supportée d'un côté par une.construction-de support d'environ 4s/45 centimètres de hauteur, en position légèrement inclinée vers l'arrière pour assurer une stabilité suffisante à la construction en tière et munie de deux points d'appui "pieds arrière" pour la pose sur le sol, pourvu en arrière et au dessus de la "plate-forme", environ dans le prolongement des"pieds arrière"de deux "joues latérales" (3) d'environ 10/15 centimètres d'hauteur, en construction ferme et non déformable avec ltélément "porteur", pour la poste des points de suspension dans lesquels pivote l'élé- ment "bascule"(5) å environ 5 à 10 centimtres audessus de la "plate-forme"; un élément "bascule" (5) suspendu au moyen de tourillons (4) dans les points de suspension montés dans les "joues latérales"(3), permettant les mouvements de l'élément "bascule"@ la hauteur de cet élément au dessus des points de suspension est adaptable; en dessous des points de suspension et dans l'interieur de la construction de ltélément "porteur" l'élément "bascule" est prolongé vers le bas jusqu' la ligne horizontale inférieure de la "plate-forme; un élément pour le support de la "plate-forme" au devant et pour la transmission des mouvements de ltélément "bascule" vers le côté devant de la "plate-forme" (6); un élément de construction rigide et indéformable composé de deux "pieds devant" d'environ 40 centimètres d'hauteur reliés au moyen de traverses (7), leurs extrémités inférieures en contact avec le sol et leurs extrémités supérieures en connection articulée avec la "plate-forme" au moyen de charnitres (8) et en connection ferme et indéformable avec des "barres ou baguettes" en position horizontale vers l'arrière et noyés dans ltépaisseur de la structure de la plate-forme (6); les extrémités postérieures sont en connection articulée avec les extrémités inférieures de l'élément "bascule" au moyen de charnières (9); les barres ou baguettes qui se trouvent aux côtés latérales sont liées au moyen de traverses (7) et les charnières spéciales (8) sont formées à base de biellettes avec leurs axes de rotation à environ 6 centimètres l'un de l'autre en construction métallique. The component elements for producing a reinforcement according to the present invention are: a "load-bearing" element (1-2) of rigid and non-deformable construction, composed of a "platform" of approximately 50 × 50 cm. (2) in a horizontal or almost horizontal position, supported on one side by a support structure of approximately 4/45 cm in height, in a slightly inclined rearward position to ensure sufficient stability for construction in full and provided with two support points "rear feet" for laying on the ground, provided behind and above the "platform", approximately in the extension of the "rear feet" of two "side cheeks" (3) about 10/15 cm high, in firm, non-deformable construction with the "load-bearing" element, for the post of suspension points in which the "tilting" element pivots (5) to about 5 10 centimeters above the "platform"; a "rocking" element (5) suspended by means of pins (4) in the suspension points mounted in the "side cheeks" (3), allowing the movements of the "rocking" element @ the height of this element above ellipsis is adaptable; below the suspension points and inside the construction of the "load-bearing" element the "tilting" element is extended downwards to the lower horizontal line of the "platform; an element for supporting the "platform" at the front and for the transmission of the movements of the "tilting" element towards the front side of the "platform" (6); a rigid and non-deformable construction element composed of two "feet in front" of approximately 40 centimeters in height connected by means of crosspieces (7), their lower ends in contact with the ground and their upper ends in articulated connection with the "platform" by means of charnitres (8) and in firm and non-deformable connection with "bars or rods" in a horizontal position towards the rear and embedded in the thickness of the platform structure (6); the rear ends are in articulated connection with the lower ends of the "rocking" element by means of hinges (9); the bars o u rods which are on the lateral sides are linked by means of crosspieces (7) and the special hinges (8) are formed on the basis of rods with their axes of rotation about 6 centimeters from each other in metal construction.

Selon des variantes 1' l'élément "plate-forme" et l'élément "porteur" peuvent être réalisés en dimensions et en formes différentes, autant que la hauteur des constructions de support peutedifférer sans sortir du cadre de l'invention.  According to variants 1 'the "platform" element and the "carrier" element can be made in different dimensions and shapes, as far as the height of the support constructions can differ without departing from the scope of the invention.

Selon une variante l'inclination de la "plate-forme" est changeable au moyen d'une particularité de la charnière articulant la "plate-forme" avec l'élément de "support devant". According to a variant, the inclination of the "platform" is changeable by means of a special feature of the hinge articulating the "platform" with the "support in front" element.

L'armature selon la présente invention comporte én soi le mouvement de plusieurs éléments en rapport mutuel; pour la réalisation d'une telle armature en forme d'utilisation pratique l'invention comprends l'arrêt des mouvements en positions souhaitées au moyen de blocages; un dispositif spécialisé et à confectionner, adapté aux mouvements des éléments de la structure, peut être ajouté afin de réaliser des positions fixes entre les deux positions extrèmes; des dispositifs pour le réglage de positions d'une chaise suivant l'invention peuvent être réalisés à base d'adaptation manuelle soit à base d'adaptation électrique. The frame according to the present invention comprises in itself the movement of several elements in mutual relation; for the production of such a frame in the form of practical use, the invention includes stopping movements in desired positions by means of blockages; a specialized device and to be made, adapted to the movements of the elements of the structure, can be added in order to achieve fixed positions between the two extreme positions; devices for adjusting the positions of a chair according to the invention can be made on the basis of manual adaptation or on the basis of electrical adaptation.
