Description

La présente invention concerne un siège destiné au travail debout.The present invention relates to a seat intended for standing work.

On connaît, par le brevet FR-2 473 864, un siège pour travail debout comportant une surface d'assise plane prolongée par un appui de bassin de forme bombée ; cette assise est portée par un bâti présentant, soit une colonne centrale munie d'un piètement en étoile à plusieurs branches, soit un montant à deux branches, agencées en "V" ou en "lambda", et qui sont pourvues chacune d'une traverse horizontale en appui sur le sol de manière à ce que l'utilisateur du siège puisse faire reposer ses pieds sur la traverse située à l'avant. On connaît également, par la demande internationale WO-84/04 235, un siège pour travail debout comportant une assise de forme particulière procurant à la fois un appui fessier vers l'arrière et un appui des cuisses vers l'avant ; dans ce dernier brevet, il est proposé plusieurs types de socles prévus pour recevoir cette assise à l'extrémité d'un montant vertical, ou légèrement incliné vers l'avant, qui est coudé à sa partie inférieure pour rejoindre la zone médiane d'un piètement en "U", lequel est muni d'un jeu de quatre roulettes roulant sur le sol pour faciliter les déplacements du siège.We know, from patent FR-2 473 864, a seat for standing work comprising a flat seat surface extended by a basin support of convex shape; this seat is supported by a frame having either a central column provided with a star base with several branches, or an upright with two branches, arranged in "V" or "lambda", and which are each provided with a horizontal cross member resting on the ground so that the seat user can rest his feet on the cross member located at the front. Also known, by international application WO-84/04 235, a seat for standing work comprising a seat of particular shape providing both a buttock support rearward and a thigh support forward; in this last patent, several types of bases are proposed which are intended to receive this seat at the end of a vertical upright, or slightly inclined towards the front, which is bent at its lower part to join the middle zone of a "U" -shaped base, which is provided with a set of four rollers rolling on the ground to facilitate movement of the seat.

Les deux types de sièges pour travail debout proposés dans les deux brevets précédents présentent, à l'usage, un certain nombre d'inconvénients liés, soit à l'encombrement trop important de leur piètement, soit à leur instabilité. En particulier, le piètement en étoile à plusieurs branches du premier siège, s'il est pratiquement devenu obligatoire dans le domaine des chaises professionnelles classiques, n'offre aucun avantage de stabilité pour un siège employé dans la station debout et, au contraire, il encombre grandement les pieds de l'utilisateur, avec le risque non négligeable que ce dernier ne s'y empêtre. De même, il n'est pas souhaitable que l'utilisateur contribue à maintenir son siège avec ses pieds, en les faisant reposer sur des traverses placées en équerre à l'extrémité des branches en "V" ou en "lambda" du piètement ; dans ce dernier cas, non seulement l'encombrement du socle est important, mais les deux traverses matérialisent au sol deux axes préférentiels autour desquels le siège peut basculer. Par ailleurs, dans le siège décrit dans la demande internationale citée, le piètement en "U" muni de ses roulettes doit être doté, pour être fermement maintenu sur le sol, d'un béquet arrière lui interdisant de reculer lorsque l'utilisateur aborde l'assise, ce qui n'est pas suffisant pour assurer une sécurité correcte ; en outre, le "U" du piètement a une forme générale anguleuse, carrée ou triangulaire, présentant donc des arêtes droites autour desquelles le siège peut facilement encore basculer.The two types of seats for standing work proposed in the two previous patents have, in use, a certain number of drawbacks linked either to the excessive bulk of their legs, or to their instability. In particular, the star base with several branches of the first seat, although it has practically become compulsory in the field of conventional professional chairs, does not offer any stability advantage for a seat used in the standing station and, on the contrary, it greatly clogs the user's feet, with the not insignificant risk that the latter will get tangled up. Likewise, it is undesirable for the user to help maintain his seat with his feet, by resting them on crosspieces placed in square at the end of the "V" or "lambda" legs of the base; in the latter case, not only the size of the base is important, but the two crossbars materialize on the ground two preferential axes around which the seat can tilt. Furthermore, in the seat described in the cited international application, the "U" -shaped base fitted with its casters must be equipped, in order to be firmly held on the ground, with a rear spoiler preventing it from moving back when the user approaches the 'sitting, which is not enough to ensure correct safety; in addition, the "U" of the base has a generally angular, square or triangular shape, therefore having straight edges around which the seat can easily still tilt.

La présente invention vise à remédier à ces inconvénients en proposant un siège destiné au travail debout, comportant une assise fixée à l'extrémité supérieure d'une colonne inclinée de bas en haut et d'arrière en avant du siège, ladite colonne étant reliée, par son extrémité inférieure, à la partie centrale d'un piètement horizontal en forme d'arc outrepassé, ou en "fer à cheval", et ouvert vers l'avant dudit siège de manière à ce que l'aplomb de ladite assise soit située juste au niveau ou en arrière de la ligne virtuelle joignant les deux extrémités de ce même arc.The present invention aims to remedy these drawbacks by proposing a seat intended for standing work, comprising a seat fixed to the upper end of a column inclined from bottom to top and from rear to front of the seat, said column being connected, by its lower end, in the central part of a horizontal base in the form of a horseshoe arch, or "horseshoe", and open towards the front of said seat so that the plumb of said seat is located just at or behind the virtual line joining the two ends of this same arc.

Interbuild, vol. 12, no. 2 Février 1965, page 42, décrit une siège ayant un piètement horizontal en forme d'arc outrepassé, qui néanmoins n'est pas destinée au travail debout.Interbuild, vol. 12, no. February 2, 1965, page 42, describes a seat with a horizontal base in the shape of an arched arc, which nevertheless is not intended for standing work.

Préférentiellement, l'arc du piètement est un demi-cercle outrepassé, de sorte qu'à l'avant du piètement, cet arc est légèrement rentrant.Preferably, the arch of the base is an overstepped semi-circle, so that at the front of the base, this arc is slightly re-entrant.

Le dégagement procuré sous l'assise par l'inclinaison de la colonne et par l'ouverture en arc du piètement permet de ne pas encombrer la zone où reposent les pieds de l'utilisateur. Par ailleurs, du fait que le piètement ne présente aucune arête susceptible de matérialiser, sur le sol, un axe de basculement du siège, ce dernier est particulièrement stable. La sécurité contre le renversement est encore notablement améliorée par la disposition judicieuse de la position horizontale de l'assise portée par la colonne inclinée. Ainsi, le centre de gravité du siège, qui passe normalement par l'assise, se trouve, suivant l'invention, à l'aplomb de la surface délimitée au sol par l'arc du piètement ; toute instabilité latérale du siège est donc immédiatement compensée par un effet de contrebalancement ramenant l'assise à sa position d'équilibre normale. Ce même effet est également apparent pour un basculement provoqué vers l'avant du siège, notamment dans la configuration préférentielle de l'invention pour laquelle l'arc du cercle formant le piètement est légèrement supérieur à 180°.The clearance provided under the seat by the inclination of the column and by the arched opening of the base allows not to clutter the area where the feet of the user rest. Furthermore, the fact that the base has no edge capable of materializing, on the ground, an axis of tilting of the seat, the latter is particularly stable. Safety against overturning is further improved by the judicious arrangement of the horizontal position of the seat supported by the inclined column. So the center gravity of the seat, which normally passes through the seat, is, according to the invention, perpendicular to the surface delimited on the ground by the arch of the base; any lateral instability of the seat is therefore immediately compensated for by a counterbalancing effect bringing the seat back to its normal equilibrium position. This same effect is also apparent for a tilting caused towards the front of the seat, in particular in the preferred configuration of the invention for which the arc of the circle forming the base is slightly greater than 180 °.

Suivant cette forme d'exécution préférée de l'invention, le piètement est constitué par un tube, normalement rond, cintré en arc de cercle d'un diamètre d'environ 50 cm, les deux extrémités dudit tube étant écartés d'une distance moindre que ledit diamètre et supérieure à l'écartement moyen des deux pieds d'une personne susceptible d'utiliser le siège, soit normalement 40 cm.According to this preferred embodiment of the invention, the base consists of a tube, normally round, bent in an arc of a circle with a diameter of about 50 cm, the two ends of said tube being spaced apart by a lesser distance. that said diameter and greater than the average spacing of the two feet of a person likely to use the seat, is normally 40 cm.

Suivant une autre caractéristique de l'invention, les deux extrémités du tube formant le piètement du siège sont pourvues de bouchons d'une matière anti-dérapante, offrant une résistance au glissement sur le sol ; le cas échéant, un ensemble de patins anti-dérapants supplémentaires sont répartis sous ledit tube. De cette manière, l'inclinaison vers l'arrière de la colonne supportant l'assise n'est pas gênante quant à la stabilité du siège vis à vis des efforts qui auraient tendance à provoquer son recul ; on a même pu constater que, sur un sol relativement lisse et carrelé, les deux seuls bouchons d'extrémité du piètement étaient suffisants pour interdire tout glissement.According to another characteristic of the invention, the two ends of the tube forming the seat base are provided with plugs of a non-slip material, offering resistance to sliding on the ground; if necessary, a set of additional non-slip pads are distributed under said tube. In this way, the inclination towards the rear of the column supporting the seat is not a hindrance as to the stability of the seat with respect to the forces which would tend to cause it to recede; we have even seen that, on a relatively smooth and tiled floor, the only two end caps of the base were sufficient to prevent any sliding.

D'autres caractéristiques et avantages de la présente invention ressortiront mieux de la description qui va suivre d'un mode de réalisation d'un siège donné à titre d'exemple non limitatif en référence au dessin annexé sur lequel :

  • la figure 1 est une vue en coupe du siège en position basse, montrant schématiquement un utilisateur en position assise, genoux fléchis,
  • la figure 2 est une vue en perspective arrière d'une première variante de réalisation du siège,
  • la figure 3 est une vue en coupe du siège en position haute, montrant schématiquement un utilisateur en position assise, genoux tendus,
  • la figure 4 est une vue en perspective avant d'une seconde variante de réalisation du siège.
Other characteristics and advantages of the present invention will emerge more clearly from the description which follows of an embodiment of a seat given by way of nonlimiting example with reference to the appended drawing in which:
  • Figure 1 is a sectional view of the seat in low position, schematically showing a user in sitting position, knees bent,
  • FIG. 2 is a rear perspective view of a first alternative embodiment of the seat,
  • FIG. 3 is a sectional view of the seat in the high position, schematically showing a user in a seated position, knees extended,
  • Figure 4 is a front perspective view of a second alternative embodiment of the seat.

Le siège représenté sur les figures comporte, conformément à la présente invention, une assise 1 fixée à l'extrémité supérieure d'une colonne 2, inclinée de bas en haut et d'arrière en avant du siège, et supportée, à son extrémité inférieure, par une embase ou piètement 3, en forme d'arc de cercle outrepassé. Préférentiellement, ce piètement 3 est formé par cintrage d'un tube de section normalement circulaire, qui est avantageusement lesté, et dont les deux extrémités sont pourvues de bouchons 4 préférentiellement réalisés en un matériau anti-dérapant.The seat shown in the figures comprises, in accordance with the present invention, a seat 1 fixed to the upper end of a column 2, inclined from bottom to top and from rear to front of the seat, and supported, at its lower end , by a base or base 3, in the form of an arched circular arc. Preferably, this base 3 is formed by bending a tube of normally circular section, which is advantageously ballasted, and the two ends of which are provided with plugs 4 preferably made of an anti-slip material.

L'inclinaison de la colonne 2 peut varier de quelques degrés autour d'une valeur moyenne de 20 degrés par rapport à la verticale, mais cette valeur n'est pas impérative et dépend, dans une large mesure, de deux facteurs de dimensionnement principaux, savoir le diamètre de l'arc du piètement 3 et la hauteur moyenne de la colonne 2, de sorte que l'aplomb vertical de l'assise 1 ne dépasse jamais la ligne virtuelle reliant les deux bouchons 4. En outre, la colonne 2 est pourvue d'un moyen de réglage télescopique 5 de la hauteur de l'assise 1 qui, au maximum, atteint 90 cm ; le moyen de réglage 5, par exemple par vérin à gaz, est commandé par un mécanisme de blocage 6 connu en soi, notamment pour les chaises professionnelles. Les figures 1 et 3 représentent respectivement, d'une manière schématique, le siège avec la colonne 2 en position basse, l'utilisateur s'appuyant sur l'assise 1 avec les genoux pliés, et le siège avec la colonne 2 en position haute, l'utilisateur ayant les jambes tendues.The inclination of column 2 can vary by a few degrees around an average value of 20 degrees from the vertical, but this value is not imperative and depends, to a large extent, on two main dimensioning factors, know the diameter of the arch of the base 3 and the average height of the column 2, so that the vertical plumb of the seat 1 never exceeds the virtual line connecting the two plugs 4. In addition, column 2 is provided with a telescopic adjustment means 5 for the height of the seat 1 which, at most, reaches 90 cm; the adjustment means 5, for example by gas spring, is controlled by a locking mechanism 6 known per se, in particular for professional chairs. Figures 1 and 3 show respectively, schematically, the seat with the column 2 in the low position, the user leaning on the seat 1 with the knees bent, and the seat with the column 2 in the high position , the user with outstretched legs.

Suivant une caractéristique originale de la présente invention, l'assise 1 présente la forme d'un cylindre horizontal, rigidement fixé au droit de la colonne 2 de sorte que ladite assise 1 n'est pas orientable par rapport à l'axe de ladite colonne 2 ; ceci permet d'éviter toute mauvaise utilisation du siège, qui doit normalement être employé pour que les efforts s'exercent dans l'axe de la colonne 2.According to an original feature of this invention, the seat 1 has the shape of a horizontal cylinder, rigidly fixed to the right of the column 2 so that said seat 1 is not orientable relative to the axis of said column 2; this avoids any misuse of the seat, which should normally be used for the forces to be exerted in the axis of column 2.

Par ailleurs, le cylindre formant l'assise 1 peut avantageusement avoir un rayon de 5 cm correspondant sensiblement à la courbe moyenne décrite par la face antérieure de l'os ischion ; de cette manière, l'appui du fessier sur l'assise 1 peut être tout à fait quelconque, soit très en avant, soit très en arrière sur ladite assise 1, la courbure de cette dernière correspondant dans tous les cas à une position anatomique offrant un confort maximum à l'utilisateur. Ce profil très neutre de l'assise 1 convient donc particulièrement bien à un siège destiné au travail en station debout, pour lequel on sait bien que les postures des utilisateurs sont très variées eu égard à leur tonus musculaire, à la longueur de leurs jambes, et à leur état de fatigue. En outre, même si, dans le mode d'exécution représenté sur les figures, l'axe de la colonne 2 passe par un diamètre de l'assise 1, il est prévu que cette dernière puisse être basculée en avant ou en arrière de ce même axe, parallèlement à elle-même, ceci afin de procurer un réglage encore plus fin à l'utilisateur, lui permettant notamment de positionner le cylindre de l'assise 1 sous ses cuisses. Le confort de l'assise 1 est également améliorée par l'utilisation, dans sa fabrication, d'une matière ferme, quoique légèrement souple, procurant un soutien naturellement adapté à l'anatomie du fessier et du bassin. En outre, la largeur de l'assise 1 est prévue pour que l'utilisateur, une fois assis, puisse, s'il le souhaite, poser ses mains de chaque côté de ses cuisses.Furthermore, the cylinder forming the seat 1 may advantageously have a radius of 5 cm corresponding substantially to the mean curve described by the anterior face of the ischial bone; in this way, the support of the buttocks on the seat 1 may be entirely arbitrary, either very forward or very backward on said seat 1, the curvature of the latter corresponding in all cases to an anatomical position offering maximum user comfort. This very neutral profile of the seat 1 is therefore particularly suitable for a seat intended for work in a standing position, for which it is well known that the postures of the users are very varied having regard to their muscle tone, to the length of their legs, and their state of fatigue. In addition, even if, in the embodiment shown in the figures, the axis of the column 2 passes through a diameter of the seat 1, it is provided that the latter can be tilted forwards or backwards from this same axis, parallel to itself, this in order to provide an even finer adjustment to the user, in particular allowing him to position the cylinder of the seat 1 under his thighs. The comfort of the seat 1 is also improved by the use, in its manufacture, of a firm material, although slightly flexible, providing support naturally adapted to the anatomy of the buttocks and the pelvis. In addition, the width of the seat 1 is provided so that the user, once seated, can, if desired, put his hands on each side of his thighs.

Dans sa variante d'exécution représentée sur la figure 4, l'assise 1 est pourvue d'un béquet arrière 7 procurant à certains utilisateurs un appui de bassin. Ce béquet 7 peut s'étendre sur toute la longueur de l'assise 1 ou seulement sur sa partie centrale. En outre, ce béquet 7, qui peut être relié de façon continue au cylindre de l'assise 1, est préférentiellement évidé, c'est-à-dire qu'il comporte deux bras latéraux 8 supportant, vers l'arrière de l'assise (1), un appui de bassin 9 pouvant être plan, bombé ou, ainsi qu'il est représenté sur la figure 4, simplement cylindrique ; dans ce dernier cas, le diamètre du cylindre formant l'appui de bassin 9 est très inférieur à celui du cylindre formant l'assise 1. L'évidement du béquet arrière 7 est notamment destiné à faciliter la préhension du siège, et sert également à délimiter une cuvette dans laquelle certains utilisateurs peuvent plus ou moins poser leur fessier.In its variant shown in Figure 4, the seat 1 is provided with a rear spoiler 7 providing some users with pelvis support. This spoiler 7 can extend over the entire length of the seat 1 or only on its central part. In addition, this spoiler 7, which can be connected continuously to the cylinder of the seat 1, is preferably hollowed out, that is to say it comprises two lateral arms 8 supporting, towards the rear of the seat (1), a basin support 9 can be flat, curved or, as shown in Figure 4, simply cylindrical; in the latter case, the diameter of the cylinder forming the pelvis support 9 is much less than that of the cylinder forming the seat 1. The recess of the rear spoiler 7 is in particular intended to facilitate gripping of the seat, and also serves to delimit a bowl in which some users can more or less put their buttocks.

On a pu constater que le siège conforme à la présente invention était non seulement très sûr mais également considéré comme très confortable par les utilisateurs qui peuvent, du fait de sa géométrie variable, aussi bien en hauteur qu'en inclinaison d'assise 1, leur permettre de choisir une position anatomique variable correspondant à leur corpulence et à leur état de fatigue ; à cet égard, cette variabilité dans les possibilités d'utilisation du siège permet, en cas de fatigue musculaire importante, de trouver une position antalgique presque immédiatement.It has been observed that the seat according to the present invention is not only very safe but also considered to be very comfortable by the users who, due to its variable geometry, both in height and in seat inclination 1, their allow to choose a variable anatomical position corresponding to their build and their state of fatigue; in this regard, this variability in the possibilities of using the seat allows, in the event of significant muscle fatigue, to find an analgesic position almost immediately.
