Abstract

A chair is proposed, which is height-adjustable, is provided with a back support (5), can optionally be fitted with rollers or runners, and whose seat surface is constructed as an air-filled ball (1), thus complying, in particular, with the orthopaedic requirements of school pupils and office workers. <IMAGE>

Description

Die Erfindung bezieht sich auf Stuhl mit einer Sitzfläche, die von einem Untergestell getragen wird, welches über drei oder vier teleskopierbare und in unterschiedlichen Höhen feststellbare Stützen in unterschiedliche Sitzhöhen gebracht werden kann, und an dem eine Rückenstütze befestigt ist.The invention relates to a chair with a seat which is supported by an underframe which can be brought to different seat heights via three or four telescopic supports which can be fixed at different heights, and to which a back support is fastened.

Ein solcher Stuhl ist aus P 33.23 171.0-16 bekannt. Dieser Stuhl zeichnet sich dadurch aus, daß Sitztiefe und Rückenlehnenhöhe gleichzeitig verstellt werden können. Der Sitz besteht aus einer harten Platte, die zur Erzielung einer günstigen Sitzstellung auch nach vorne geneigt werden kann.Such a chair is known from P 33.23 171.0-16. This chair is characterized by the fact that seat depth and backrest height can be adjusted at the same time. The seat consists of a hard plate, which can also be tilted forward to achieve a favorable seating position.

Nachteil dieser Konstruktion ist, daß die Sitzflächenneigung über einen Kippmechanismus konstruktiv aufwendig und teuer ist und daß die Verstellung der Sitzflächenneigung von der Handhabung kompliziert und von der Sicherheit her nur schwer technisch lösbar erscheint.Disadvantages of this construction are that the seat inclination is structurally complex and expensive via a tilting mechanism and that the adjustment of the seat inclination is complicated to handle and appears to be technically difficult to solve from a safety standpoint.

Ein weiterer Nachteil besteht darin, daß die Sitzfläche relativ hart ist und in seiner ergonomisch vorbestimmten Verformung nur für ein ganz bestimmtes Spektrum von unterschiedlichen Körpergrößen abgestimmt sein kann.Another disadvantage is that the seat is relatively hard and its ergonomically predetermined deformation can only be adjusted for a very specific spectrum of different body sizes.

Dazu kommt, daß einem kontinuierlichen Haltungswechsel, auch nach seitlich, wie dieser gerade bei Kindern erforderlich ist, keine Rechnung getragen wird.In addition, a continual change of posture, even to the side, as is especially necessary with children, is not taken into account.

Ziel einer nach vorne neigbaren Sitzfläche ist es, den Winkel zwischen Oberschenkel und Rumpf zu öffnen, damit Bauchraum und Unterleib hinreichend Platz für Durchblutung und Bewegung haben.The aim of a seat that can be tilted forward is to open the angle between the thigh and torso so that the abdomen and abdomen have enough space for circulation and movement.

Grundsätzlich bekannt ist ebenfalls, daß anstatt eines Stuhles ein Sitzball verwendet wird. Dieser Sitzball wird auch aus medizinischer Seite für die Therapie und Rekonvaleszenz von wirbelsäulengeschädigten Personen eingesetzt. Infolge des notwendigen Ausbalancierens auf dem Sitzball wird die Wirbelsäulenmuskulatur trainiert. Gleichzeitig kann die sogenannte "Sattelsitzhaltung", bei der der Bauchraum in vorteilhafer Weise geöffnet ist, eingenommen werden. Infolge der starken Vorrotation des Beckens wird zudem die Wirbelsäule in lordosierender Form zur Aufrichtung gebracht.It is also fundamentally known that a seating ball is used instead of a chair. This seat ball is also used from a medical point of view for the therapy and convalescence of people with spinal injuries. As a result of the necessary balancing on the sitting ball, the spinal muscles are trained. At the same time, the so-called "saddle seat posture", in which the abdominal cavity is advantageously opened, can be adopted. Due to the strong pre-rotation of the pelvis, the spine is also raised in a lordosing form.

Es war zu lesen, daß in der Schweiz diese Sitzform in Schulen als Versuch zur Anwendung für Grundschulkinder kam.
Nachteil dieses Sitzballs ist, daß er nach dem Aufstehen wegrollt. Des weiteren nimmt er auf unterschiedliche Körpergrößen keine Rücksicht; im Gegenteil, wer größer ist, sinkt meist auch tiefer ein, was insbesondere in Relation zu einer fixierten Tischhöhe problematisch ist.
Ein weiterer Nachteil eines Sitzballs ist, daß das ständige Ausbalancieren doch recht anstrengend wird; eine Ausruhmöglichkeit des Rückens jedoch nicht geboten wird.It could be read that in Switzerland this type of seat was used in schools as an experiment for primary school children.
The disadvantage of this ball is that it rolls away after getting up. Furthermore, he takes no account of different body sizes; on the contrary, whoever is taller usually sinks deeper, which is particularly problematic in relation to a fixed table height.
Another disadvantage of a sitting ball is that the constant balancing is quite exhausting; however, there is no possibility of resting your back.

Ziel der vorliegenden Neuerung war es deshalb, einen höhenverstellbaren Stuhl mit Rückenstütze zu schaffen, der einen flexiblen Sitz hat, der in konstruktiv einfacher und damit preisgünstiger Form unterschiedlichen Sitzneigungen und Sitzstellungen sowie einem kontinuierlichen Haltungswechsel Rechnung trägt.The aim of the present innovation was therefore to create a height-adjustable chair with back support, which has a flexible seat, which takes account of different seat inclinations and seating positions as well as a continuous change of posture in a structurally simple and therefore inexpensive form.

Diesen und weiteren Zielen wird die Neuerung gemäß dem Oberbegriff des Anspruchs 1 durch die Kennzeichen 1 - 8 gerecht.The innovation according to the preamble of claim 1 by the marks 1-8 meets these and other goals.

Anhand in den Figuren mehr oder minder schematisch dargestellten Ausführungsformen eines Stuhles wird die Erfindung näher erläutert. Es zeigt die:

  • FIG. 1 eine perspektivische und teilweise explosive Ansicht einer beispielsweisen Ausführungsform des Stuhles
  • FIG. 2 eine alternative Ausführungsform einer Teleskopstütze des Stuhles
  • FIG.3 eine Seitenansicht eines schematisierten Sitzenden auf dem Stuhl in drei verschiedenen Sitzhaltungen
  • FIG. 4 eine Seitenansicht einer weiteren Ausführungsform des Stuhls.
The invention is explained in more detail with the aid of the more or less schematically illustrated embodiments of a chair in the figures. It shows the:
  • FIG. 1 is a perspective and partially explosive view of an exemplary embodiment of the chair
  • FIG. 2 shows an alternative embodiment of a telescopic support of the chair
  • 3 shows a side view of a schematic seated person on the chair in three different sitting positions
  • FIG. 4 is a side view of another embodiment of the chair.

Das Grundgestell des in FIG. 1 dargestellten Stuhles besteht aus einem zu einem geschlossenen Kreis gebogenem Rohrring 2, an dem vier Teleskopstützen 3 in einer gleichmäßigen Viererteilung des Kreises nahezu senkrecht gegenüber der Kreisebene angeschweißt sind. Diese Teleskopstützen 3 stehen in leichter Gradstellung nach Außen, damit ein Wackeln des Gestells eingeschränkt ist, zumal die Teleskopstützen 3 infolge ihrer Verstellbarkeit ein Spiel aufweisen. Die Teleskopstützen 3 bestehen nämlich aus einem Innenrohr 8 und einem mit mehreren abstandsgleichen Bohrungen vorgesehenem Außenrohr 9, welches über eine ansich bekannte Verstellvorrichtung 10 (Kugelschnapp-Prinzip) verstellt werden kann, indem der Kugelschnapper des Innenrohres 8 in die Bohrungen des Außenrohres 9 einrastet. Die Innenrohre 8 schließen bodenseitig mit Standflächen 11 ab, sodaß eine ausreichende Auflagefläche gewährleistet wird.
Der Rohrring 2 bettet einen Ball 1 ein, wobei der Rohrring 2 vom Durchmesser her etwa um 10 % kleiner als der des Ball 1 ist. Auf diese Weise ist ein ausreichendes Verklemmen des Balles 1 auf dem Gestell gegeben, ohne daß weitere Befestigungsverbindungen geschaffen werden müssen. Der Ball 1 selbst ist eine straff mit Luft gefüllte mit Ventil verschlossenen Kunststoffblase.The base frame of the in FIG. 1 shown chair consists of a tube ring 2 bent into a closed circle, on which four telescopic supports 3 are welded in an even division of the circle almost perpendicular to the plane of the circle. These telescopic supports 3 are at a slight degree to the outside, so that wobbling of the frame is restricted, especially since the telescopic supports 3 have a play due to their adjustability. The telescopic supports 3 consist namely of an inner tube 8 and an outer tube 9 provided with a plurality of equally spaced bores, which can be adjusted via a known adjusting device 10 (ball snap principle) by the ball snapper of the inner tube 8 snapping into the bores of the outer tube 9. The inner tubes 8 end on the bottom with standing surfaces 11, so that a sufficient contact surface is ensured.
The pipe ring 2 embeds a ball 1, the pipe ring 2 being about 10% smaller in diameter than that of the ball 1. In this way, there is sufficient jamming of the ball 1 on the frame without the need for additional fastening connections. The ball 1 itself is a tightly air-filled plastic bubble sealed with a valve.

Die Verwendung eines Balles als Sitzfläche ist auch deshalb besonders vorteilhaft, da diese Fläche von unterschiedlichen Seiten genutzt werden kann, wie dies später bei der Erläuterung der Figur 3 noch näher beschrieben wird. Ein weiterer Vorteil eines luftgefüllten Balles gegenüber beispielsweise einem luftgefüllten Kissen besteht darin, daß infolge des großen verschiebbaren Volumen sehr unterschiedliche Sitzneigungen formbar sind und dies ohne daß sich ein starker Druck unter der Körperauflagefläche ergibt.
An dem Rohrring 2 ist mittelachsig zwischen je zwei Teleskopstützen 3 ein Rückenstützenträger 4 angeschweißt.
Dieser Rückenstützenträger 4 besteht aus einem radial gebogenen Rohr, welches tangential in einem gewissen Abstand zum Ball 1 verläuft. Dieser Abstand ist so gewählt, daß beim Be-Sitzen das Ausbauchen des Balles 1 nicht beeinträchtigt wird und eine Beschädigung des Balles vermieden wird.The use of a ball as a seating surface is also particularly advantageous because this surface can be used from different sides, as will be described in more detail later in the explanation of FIG. 3. Another advantage of an air-filled ball over, for example, an air-filled pillow is that, due to the large displaceable volume, very different seat inclinations can be formed and this does not result in a strong pressure under the body support surface.
A back support bracket 4 is welded to the tubular ring 2 between two telescopic supports 3 in the center axis.
This back support bracket 4 consists of a radially bent tube, which runs tangentially at a certain distance from the ball 1. This distance is chosen so that the bulging of the ball 1 is not impaired when sitting and damage to the ball is avoided.

An dem ebenen Ende des Rückenstützträgers 4 ist quer diesem gegenüber ein horizontal liegender konkav gebogener Rohrabschnitt 6 angeschweißt, welcher mit einem weichen elastischen Materialüberzug 7 umhüllt ist.At the flat end of the back support beam 4, a horizontally lying concave pipe section 6 is welded transversely opposite it, which is covered with a soft elastic material covering 7.

Rohrabschnitt 6 und Materialüberzug 7 bilden die Rückenstütze 5.
In einer weiteren Ausführungsform der Erfindung könnte die Rückenstütze 5 ebenfalls in einer Größe wie dies bei normalen Bürodrehstühlen der Fall ist, ausgeführt sein, um eine größere Rückenauflagefläche zu bieten.
Die Rückenstütze 5 befindet sich bei Einsetzen des Benutzers in etwa auf der Höhe der Lordosenwirbelsäule. Die Rückenstütze dient zur gelegentlichen Entspannung der Wirbelsäule des Sitzenden bei Einnahme der hinteren Sitzposition, wie dies Figur 3 Abbildung A zeigt.
Die Hauptzeit verbringt der Sitzende erfahrungsgemäß in der vorderen Sitzposition, wie das Figur 3 Abbildung B zeigt.
Figur 3 Abbildung C zeigt den Sitzenden bei einer Sitzposition 180° um die Körperachse gedreht gegenüber der üblichen Sitzhaltung, wobei die Rückenstütze 5 als Bauchstütze genutzt wird; der Rückenstützenträger 4 befindet sich hier zwischen den Beinen. Auch diese Sitzhaltung bewirkt eine kurzzeitige Entspannung der Wirbelsäulenmuskulatur.Pipe section 6 and material covering 7 form the back support 5.
In a further embodiment of the invention, the back support 5 could also be of a size, as is the case with normal office swivel chairs, in order to offer a larger back support surface.
The back support 5 is approximately at the level of the lumbar spine when the user is inserted. The back support is used for occasional relaxation of the spine of the seated person when taking the rear sitting position, as shown in Figure 3 Figure A.
Experience shows that the seated person spends most of their time in the front sitting position, as shown in Figure 3 Figure B.
Figure 3 Figure C shows the seated person in a sitting position rotated 180 ° around the body axis compared to the usual sitting posture, the back support 5 being used as an abdominal support; the back support bracket 4 is here between the legs. This sitting position also causes a brief relaxation of the spinal muscles.

Figur 2 zeigt eine alternative Ausführungsform einer Teleskopstütze 3. Bei dieser Ausführungsform sind an den Innenrohren 8 lenkbare Rollen 12 befestigt, die vorteilhafterweise lastabhängig gebremst sind. Mit dieser Ausführungsform eignet sich der Stuhl für den Einsatz im Büro.Figure 2 shows an alternative embodiment of a telescopic support 3. In this embodiment, steerable rollers 12 are attached to the inner tubes 8, which are advantageously braked depending on the load. With this embodiment, the chair is suitable for use in the office.

Figur 4 zeigt eine weitere Ausführungsform der Erfindung, bei der der Rückenstützenträger 4 ebenfalls aus einem Innen- und einem Außenrohr besteht, welches über eine nicht näher beschriebene herkömmliche Klemmvorrichtung in verschiedenen Stellungen gehalten wird, sodaß eine Höhenverstellbarkeit der Rückenstütze gegeben ist.Figure 4 shows a further embodiment of the invention, in which the back support bracket 4 also consists of an inner and an outer tube, which is held in various positions by means of a conventional clamping device, not described, so that the back support can be adjusted in height.
