Description

Siège ergonomique réglable. Adjustable ergonomic seat.
L'invention concerne un siège ergonomique réglable permet¬ tant entre autres de s'asseoir en appui sur les genoux, d'effectuer certaines rééducations dans cette position ou dans un usage normal, etc.The invention relates to an adjustable ergonomic seat allowing, among other things, to sit in support on the knees, to carry out certain rehabilitations in this position or in normal use, etc.
Une position naturelle de repos et de relaxation consis¬ te à s'asseoir sur les talons en conservant un appui sur les genoux. Cependant, compte-tenu de la morphologie et de la souplesse de l'individu, cette position est sou¬ vent difficile à prendre et à conserver.A natural position of rest and relaxation consists of sitting on your heels while keeping your support on your knees. However, given the morphology and flexibility of the individual, this position is often difficult to take and maintain.
La présente invention vise à créer un siège permettant de prendre une telle position et de la conserver de manière confortable, tout en pouvant s'adapter à des individus de tailles différentes ou à des positions variées d'un même individu, grâce à un système de réglage incorporé.The present invention aims to create a seat making it possible to take such a position and to keep it in a comfortable manner, while being able to adapt to individuals of different sizes or to various positions of the same individual, thanks to a system of incorporated adjustment.
A cet effet, le siège selon l'invention est caractérisé par le fait qu'il comprend une assise reliée à un sup¬ port dont au moins la région opposée à ladite assise est sensiblement sphérique, la liaison entre l'assise et le support étant réalisée par une tige filetée avec interpo¬ sition éventuelle d'entretoises amovibles.To this end, the seat according to the invention is characterized in that it comprises a seat connected to a support, at least the region opposite to said seat is substantially spherical, the connection between the seat and the support being produced by a threaded rod with possible interpo¬ sition of removable spacers.
Grâce à l'invention, on obtient un siège extrêmement sim¬ ple et économique qui permet, grâce à son assise, un re¬ pos confortable de l'utilisateur, tandis que le support arrondi permet d'effectuer divers mouvements d'assouplis¬ sement, de gymnastique, de rééducation, etc. Le réglage de la hauteur du support au moyen d'entretoises simple¬ ment enfilées sur une tige filetée de liaison, permet, sans compliquer le siège ni nuire à sa solidité, d'adap¬ ter la hauteur de l'assise à divers individus ou à diver¬ ses attitudes ou positions d'un même individu. Le dispositif de l'invention peut être utilisé en appui sur les genoux ou en position normale. Cette dernière po¬ sition peut être utilisée pour des rééducations, par exem¬ ple de la colonne vertébrale.Thanks to the invention, an extremely simple and economical seat is obtained which, thanks to its seat, allows the user to rest comfortably, while the rounded support makes it possible to carry out various movements of flexibility. , gymnastics, rehabilitation, etc. The adjustment of the height of the support by means of spacers simply threaded on a threaded connecting rod, allows, without complicating the seat or affecting its solidity, to adapt the height of the seat to various individuals or to different attitudes or positions from the same individual. The device of the invention can be used in support on the knees or in normal position. This latter position can be used for rehabilitations, for example of the spine.
Avantageusement, ladite assise est profilée selon une for¬ me sensiblement concave.Advantageously, said seat is profiled in a substantially concave form.
De préférence, la tige filetée est vissée dans un écrou prisonnier de l'assise et dans une douille taraudée fixée dans le support. L'ensemble est ainsi partiellement ou to¬ talement démontable pour occuper un encombrement réduit pour le transport ou en dehors des périodes d'utilisa¬ tion.Preferably, the threaded rod is screwed into a captive nut of the seat and into a threaded socket fixed in the support. The assembly is thus partially or completely detachable to occupy a reduced space requirement for transport or outside periods of use.
Dans une forme de réalisation de l'invention, le support est sphérique à l'exception de sa face tournée vers l'as¬ sise, qui est sensiblement plane et sur laquelle débou¬ che le moyen de fixation sur l'assise, par exemple l'ex¬ trémité de la douille taraudée. Le support sphérique per¬ met, avec une esthétique optimale, d'obtenir une mobili¬ té maximale du siège.In one embodiment of the invention, the support is spherical with the exception of its face facing the seat, which is substantially flat and on which the fixing means on the seat opens, for example the end of the threaded sleeve. The spherical support allows, with optimal aesthetics, to obtain maximum mobility of the seat.
L'invention sera bien comprise à la lecture de la descrip¬ tion suivante faite en se référant au dessin annexé dans lequel :The invention will be clearly understood on reading the following descrip¬ tion made with reference to the accompanying drawing in which:
La figure 1 est une vue schématique en perspective d'un siège selon un exemple de réalisation de l'inven¬ tion, en cours d'assemblage ; la figure 2 est une vue schématique en élévation, partiellement en coupe, du support du siège de la figure 1 ; la figure 3 est une vue schématique en élévation, partiellement en coupe, de l'assise du siège de la figure 1, et la figure 4 est une vue schématique en plan de l'assise de la fi¬ gure 3. Dans l'exemple représenté à la figure 1, le siège selon l'invention est constitué par une assise profilée 1 re¬ liée à un support 2 sensiblement sphérique par une tige filetée 3, avec ou sans interposition d'entretoises 4.Figure 1 is a schematic perspective view of a seat according to an exemplary embodiment of the invention, during assembly; Figure 2 is a schematic elevational view, partially in section, of the seat support of Figure 1; Figure 3 is a schematic elevational view, partially in section, of the seat of the seat of Figure 1, and Figure 4 is a schematic plan view of the seat of the fi¬ gure 3. In the example shown in FIG. 1, the seat according to the invention consists of a profiled seat 1 re¬ linked to a support 2 substantially spherical by a threaded rod 3, with or without the interposition of spacers 4.
Le support 2 est constitué par une boule dont une face 5 est plane (figure 2). Une douille taraudée 6, noyée dans la boule 2, débouche dans la face plane 5 et peut rece¬ voir la tige filetée 3 de liaison avec l'assise 1.The support 2 consists of a ball, one face 5 of which is planar (FIG. 2). A threaded socket 6, embedded in the ball 2, opens into the flat face 5 and can receive the threaded rod 3 for connection with the seat 1.
L'assise 1 (figures 3 et 4) est formée en matériau moulé à la forme incurvée convenable, un écrou 7 étant noyé dans la face inférieure de l'assise 1 et recevant la ti¬ ge filetée 3.The seat 1 (Figures 3 and 4) is formed of molded material with a suitable curved shape, a nut 7 being embedded in the underside of the seat 1 and receiving the threaded rod 3.
Pour régler la hauteur par rapport au sol de l'assise 1, on peut intercaler entre l'assise 1 et le support 2 une ou plusieurs éntretoises annulaires 8, ou bien visser la boule 2 directement en omettant les entretoises 8.To adjust the height from the ground of the seat 1, one or more of the annular spacers 8 can be inserted between the seat 1 and the support 2, or else screw the ball 2 directly, omitting the spacers 8.
La tige filetée 3 peut être remplacée par une vis dont la tête est noyée dans l'assise 1.The threaded rod 3 can be replaced by a screw whose head is embedded in the seat 1.
L'assise 1 peut être réalisée par exemple en matière syn¬ thétique moulée, en bois comprimé. La boule 2 peut être en bois. The seat 1 can be made for example of molded synthetic material, of compressed wood. Ball 2 can be made of wood.
