Abstract

The stool, for work purposes, esp. for writing, is in the form of a rocking stool where the balance must be actively achieved by a corresponding distribution of the body weight on the seat and the two legs of the sitter. The chair leg is shaped like a segment of a sphere or an ellipsoid, or is saucer-shaped. The centre of gravity of the stool and body system is positioned beneath the metacentre of the saucer shape. The axis of the stool can be pushed forward towards the axis of the segment. The leg is weighted and gives the stool a stable equilibrium, when there is no occupant.

Description

Arbeitsschaukelstuhl Work rocking chair

In der Offenlegungsschrift 1654341 ist ein Schaukelstuhl beschrieben, dessen Fuß aus einem auf dem Boden aufliegenden Kugelsegment besteht. Ziel deses Schaukelstuhls ist es, daß er eine stabile Lage einnimmt, aus jeder Abweichung, Kippung durch Wahl eines Schwerpunkts unter dem Mittelpunkt der Kugelschale wieder in die aufrechte Stellung zurückkehrt. Es handelt sich um einen Schaukelstuhl zum Zwecke der Bequemlichkeit.In the laid-open specification 1654341 a rocking chair is described, whose foot consists of a spherical segment resting on the ground. Goal deses It is the rocking chair that it assumes a stable position, from every deviation, Tilting again by choosing a center of gravity under the center of the spherical shell returns to the upright position. It is a rocking chair for Purposes of convenience.

Auch Arbeitsstühle werden so gebaut, daß sie möglichst bequemes Sitzen ermöglichen. Wird dabei eine körpergerechte Haltung erzielt, so ist dies zwar besser, als in schlechter Haltung möglichst bequem zu sitzen. Gesünder ist es allerdings, den Stuhl so zu bauen, daß die Muskeln aktiv den Körper in eine gute haltung bringen.Work chairs are also built to be as comfortable as possible enable. If a correct posture is achieved, this is better, than sitting as comfortably as possible in a bad posture. It is healthier, however, to build the chair so that the muscles actively bring the body into good posture.

Zweitens wird kein Pianist sich beim Klavierspielen anlehnen, er wird sich eher leicht nach vorne beugen, da die so entstehende Beinspannung seine präsenz erhöht; diese Idee ist auch für kreatives Schreiben nicht von der Sand zu weisen.Second, no pianist will lean on to play the piano, he will rather bend forward slightly, as the leg tension created in this way is present elevated; this idea cannot be dismissed from the sand, even for creative writing.

Also ein Stuhl, bei dem die Balance aktiv durch eine entsprechende Verteilung des Körpergewichts auf das Gesäß und die beiden Beine erzeugt werden muß, 130020/0451 Dies ist bei dem bekannten Nelkschemel, der nur ein Bein in der Iiitte hat, der Fall. iiird aber ein Kugelsegment als Grundfläche gewählt so, daß der mittelpunkt des Eugelsegments unterhalb des Schwerpunkts des Gesamtsystems Stuhl-Körper zu liegen kommt, wird die Instabilität geringer und kann konstruktiv den Erfordernissen angepaßt werden.So a chair in which the balance is actively supported by a corresponding Distribution of body weight to the buttocks and both legs are generated must, 130020/0451 This is the case with the well-known carnation stool, which only has one leg in the Iitte has the case. iiird, however, a spherical segment is chosen as the base area so that the center of the Eugen segment below the center of gravity of the entire chair-body system comes to rest, the instability is less and can constructively meet the requirements be adjusted.

Der Unterschied zum erwähnten Patent besteht erstens in dem Zweck (Arbeitsstuhl, nicht Bequemlichkeit), in der Patentunterklasse; zweitens darin, daß gerade die Instabilität, nicht die Stabilität gesucht wird.The difference to the patent mentioned is firstly in the purpose (Work chair, not comfort), in the patent subclass; secondly in that instability, not stability, is sought.

Variationen: Durch Vahl eines Ellipsoides statt eines gugelsegments können die erforderlichen dückstellkräfte für die Vor-undzurück- bzw. die Rechts-links-Kippbewegung unterschiedlich werden. Die beiden Grenzfälle wären ein längs- oder quer-gestellter Zylindermantel.Variations: By choosing an ellipsoid instead of a gel segment can apply the necessary restoring forces for the forward and backward or the right-left tilting movement become different. The two borderline cases would be longitudinal or transverse Cylinder jacket.

Durch Beschwerung des Fußes (Bleieinguß) kann erreicht werden, daß der Stuhl wie ein Stehaufmännchen stabil steht, beim Sitzen der Gesamtschwerpunkt aber über dem Netazentrum liegt, da also eine instabile Lage erhalten bleibt.By weighting the foot (lead casting) it can be achieved that the chair is stable like a man standing upright, the overall focus when sitting but is above the Netazentrum, so an unstable situation remains.

Durch versetzen der Stelle, wo das Bein in das Segment eingesetzt wird, kann Beinspannung in senkrechter wellung des Stuhls erzielt werden.(fig. 2) LeerseiteBy moving the point where the leg is inserted into the segment, leg tension can be achieved in the vertical curvature of the chair (fig. 2).
