Abstract
Description
La présente invention a pour objet un dispositif de commande destiné à être monté sur une chaise de dactylo en vue de permettre le réglage en hauteur de la surface de siège et le réglage en inclinaison du dossier à l'aide d'un seul levier d'actionnement disposé à l'intérieur du dispositif et susceptible d'être facilement manoeuvré manuellement par l'utilisateur assis sur la chaise.The subject of the present invention is a control device intended to be mounted on a typist's chair in order to allow the height adjustment of the seat surface and the adjustment of the backrest inclination using a single lever. actuation arranged inside the device and capable of being easily operated manually by the user seated on the chair.
Le dispositif suivant l'invention est défini à la revendication 1.The device according to the invention is defined in claim 1.
Il comprend un levier de commande à profil en forme de Z qui présente en fait un seul axe de pivotement et qui est engagé à travers une lumière à profil en L pratiquée dans la paroi latérale du carter qui renferme le dispositif. Ce levier peut de ce fait affecter quatre positions normales de fonctionnement, à savoir :
- 1) Une première position stable de repos, pour laquelle la surface de siège comme le dossier restent immobilisés dans la position qui leur a été affectée,
- 2) Une deuxième position, soulevée vers le haut, pour laquelle une pression est exercée sur un petit piston hydraulique de commande qui autorise le mouvement de soulèvement ou d'abaissement de la surface de siège, celle-ci pouvant ainsi être amenée à la hauteur désirée par l'utilisateur,
- 3) Une troisième position, déplacée vers le bas, qui assure l'actionnement du petit piston de commande d'un autre vérin qui autorise le réglage de l'inclinaison du dossier aussi bien vers l'avant que vers l'arrière avec un déplacement correspondant de la surface de siège. Le dossier peut de la sorte être amené à l'inclinaison désirée par l'utilisateur,
- 4) Une quatrième position du levier pour laquelle celui-ci est abaissé et repoussé vers l'arrière, en permettant au dossier et à la surface de siège de se déplacer librement en synchronisme, sans assumer aucune position stable.
- 1) A first stable rest position, for which the seat surface and the backrest remain immobilized in the position which has been assigned to them,
- 2) A second position, raised upwards, for which pressure is exerted on a small hydraulic control piston which allows the movement of raising or lowering of the seat surface, the latter thus being able to be brought up to height desired by the user,
- 3) A third position, moved down, which ensures the actuation of the small control piston of another cylinder which allows the adjustment of the inclination of the backrest both forwards and backwards with a displacement corresponding to the seat area. The backrest can thus be brought to the angle desired by the user,
- 4) A fourth position of the lever for which it is lowered and pushed back, allowing the backrest and the seat surface to move freely in synchronism, without assuming any stable position.
Un ressort spirale en acier permet de compenser le poids du dossier sur son axe de rotation, de manière à en faciliter les déplacements une fois que son piston de commande a été libéré.A steel spiral spring compensates for the weight of the backrest on its axis of rotation, so as to facilitate movement once that its control piston has been released.
La disposition particulière des étriers pour le montage de la surface de siège, tous deux articulés sur des axes horizontaux dont l'un est lié à l'étrier qui supporte le dossier, permet d'effectuer le déplacement automatique de la surface de siège lors de la modification de l'inclinaison du dossier, ce qui constitue une autre caractéristique avantageuse de la chaise de dactylo.The special arrangement of the stirrups for mounting the seat surface, both articulated on horizontal axes, one of which is linked to the stirrup which supports the backrest, makes it possible to carry out the automatic displacement of the seat surface during the modification of the inclination of the backrest, which is another advantageous characteristic of the typist chair.
Les caractéristiques ci-dessus définies vont maintenant être décrites en détail en étant illustrées au moyen du dessin annexé, dans lequel :
- La figure 1 est une vue de côté du dispositif suivant l'invention, représenté à sa position de repos.
- La figure 2 est une vue en plan schématique de ce dispositif, les étriers et la surface de siège n'étant pas représentés.
- La figure 3 est une vue de côté du même dispositif, représenté au cours de la manoeuvre destinée au réglage en hauteur de la surface de siège.
- La figure 4 montre le levier de commande à la position abaissée, pour permettre de libérer le dossier et d'assurer le réglage de son inclinaison, avec un déplacement correspondant de la surface de siège.
- La figure 5 montre le levier de commande après abaissement et déplacement vers l'arrière, pour assurer la libération complète de l'inclinaison du dossier avec un déplacement correspondant de la surface de siège.
- Figure 1 is a side view of the device according to the invention, shown in its rest position.
- Figure 2 is a schematic plan view of this device, the stirrups and the seat surface not being shown.
- Figure 3 is a side view of the same device, shown during the maneuver for adjusting the height of the seat surface.
- FIG. 4 shows the control lever in the lowered position, to allow the backrest to be released and the angle to be adjusted, with a corresponding displacement of the seat surface.
- Figure 5 shows the control lever after lowering and moving backwards, to ensure complete release of the backrest inclination with a corresponding movement of the seat surface.
Comme on peut le relever en fig. 1 et 2, le dispositif comprend un unique levier de commande 1, susceptible d'être facilement actionné par l'utilisateur assis sur la chaise ; ce levier 1 est articulé en 2 sur l'une des parois du carter 3 qui renferme le dispositif et il est équipé d'une poignée de préhension non représentée, propre à être facilement saisie par la main de l'utilisateur.As can be seen in fig. 1 and 2, the device comprises a single control lever 1, capable of being easily actuated by the user seated on the chair; this lever 1 is articulated in 2 on one of the walls of the
Le levier 1 traverse une lumière 4 à profil en L, pratiquée dans la paroi opposée du carter 3, si bien qu'il peut être soumis à des déplacements vers le haut et vers le bas, ainsi que vers l'arrière à cette position basse, en fonction de l'action de la personne assise sur la chaise.The lever 1 passes through a light 4 with an L-shaped profile, formed in the opposite wall of the
Le déplacement du levier 1 vers le haut (fig. 3) implique simultanément une rotation suivant son propre axe 2 qui opère le soulèvement de la partie coudée 5 dudit levier en provoquant le pivotement d'un premier bras 6 autour de son pivot 7, ce qui a pour effet de comprimer le petit piston 8 et de provoquer en conséquence la libération du mouvement vertical de soulèvement ou d'abaissement de la surface de siège, suivant la direction indiquée par la flèche double F.The displacement of the lever 1 upward (fig. 3) simultaneously involves a rotation along its
En abaissant le levier 1 jusqu'à la position illustrée en fig. 4, on agit sur un second bras 9, lui aussi articulé sur le même pivot 7 sur lequel est monté le bras 6, en provoquant la rotation de ce bras 9 et la compression subséquente du petit piston 10, lequel libère le vérin 11 en permettant de la sorte la modification de l'inclinaison de l'étrier qui forme support pour le dossier 12, avec un déplacement correspondant de la surface de siège 15 qui prend appui sur des étriers 16 et 17 montés à articulation sur les pivots 18 et 19 ; ce dossier peut de la sorte être amené par l'utilisateur à l'inclinaison désirée.By lowering lever 1 to the position illustrated in fig. 4, a
Le déplacement du levier 1 vers l'arrière à l'intérieur de la partie horizontale de la lumière 4 permet de libérer définitivement la manoeuvre d'orientation du dossier 12, dans un sens comme dans l'autre, autour de son axe de pivotement 13, avec un déplacement correspondant de la surface de siège 15 sur ses propres pivots 18 et 19.The movement of the lever 1 backwards inside the horizontal part of the light 4 makes it possible to definitively release the orientation maneuver of the
Un ressort spirale en acier 14 disposé autour du pivot de rotation 13 permet de compenser le poids du dossier 12, en vue de faciliter le déplacement de celui-ci une fois que son piston de commande 10 a été libéré.A steel
Comme on l'a souligné précédemment, on prévoit que la surface de siège 15 prenne appui sur les étriers 16 et 17 articulés sur leurs pivots respectifs 18 et 19, comme clairement montré aux figures du dessin annexé, cette surface de siège pouvant ainsi se déplacer longitudinalement de manière automatique en fonction de l'inclinaison du dossier 12, ce qui confère un avantage substantiel pour la commodité de l'utilisateur puisque la position de la surface de siège suit de manière automatique l'inclinaison du dossier.As previously pointed out, provision is made for the
