Abstract

The spherical-sectioned shell (2) is fixed to the central column (1) of a height-adjustable bottom frame (U) of a swivel office chair. The ball (3) is fixed to the shell by means of a leather ball-cover (4) gripping over the edge of the shell and positively fixed underneath the edge. The cover is opened and closed preferably by sliding clasp fasteners. Two back-rests (5) extend upwards over the ball and are mounted on the underneath frame.

Description

Die Erfindung betrifft einen Stuhl, dessen Sitzfläche durch einen Ball gebildet ist, welcher in einer Kugelabschnitt-Schale ruht, die über eine zentrale Stütze mit der Mittelsäule eines höhenverstellbaren Büro-Drehstuhl-Untergestelles fest verbunden ist.The invention relates to a chair, the seat is formed by a ball, which in a spherical segment shell rests over a central column with the center column of a height-adjustable office swivel chair base connected is.

Ein Stuhl dieser Art ist aus AT 000 018 U1 bekannt. Bei diesem bekannten Stuhl ist das Untergestell mittels Gasdruckfeder oder Gewinde höhenverstellbar und hat fünf Ausleger mit Rollen oder Gleitern. Der Durchmesser des Balles beträgt 24-36 cm, je nach Anwendungsbereich. Die Schale entspricht einem Kugelabschnitt, dessen Durchmesser etwa 10% kleiner sein kann als der des Balles, so daß der Ball satt in der Schale ruht. Durch die Höhenverstellbarkeit ist gewährleistet, daß der Stuhl sowohl bei normaler Arbeitstischhöhe verwendet werden kann, aber ebenso als Stehhilfe für Stehpulte, Zeichentische, Bars, in Küchen etc.A chair of this type is known from AT 000 018 U1. At this known chair is the base by means of gas pressure spring or thread height adjustable and has five brackets with Rolling or gliding. The diameter of the ball is 24-36 cm, depending on the area of application. The bowl corresponds to one Ball section, the diameter of which can be approximately 10% smaller than that of the ball, so that the ball rests well in the bowl. The height adjustment ensures that the chair can be used both at normal work table height but also as a standing aid for standing desks, drawing tables, bars, in kitchens etc.

In der Praxis hat sich gezeigt, daß ein Stuhl der vorstehend geschilderten Art mit dem Nachteil behaftet ist, daß bei aus Gründen der freien Verformung des Balles erwünschter relativ flacher Ausbildung der Schale der Ball aus dieser leicht herausgedrückt werden kann, was unter Umständen auch zu einem Sturz der sitzenden Person führen kann. Eine Befestigung mittels Saugnäpfen, wie sie im Stand der Technik vorgesehen war, erweist sich als kompliziert und unzureichend.In practice it has been shown that a chair of the above described type has the disadvantage that at more desirable for reasons of free deformation of the ball flatter the bowl the ball out of this easily can be expressed, which may also result in a Can cause the seated person to fall. An attachment by means of Suction cups, as was provided in the prior art, turns out to be complicated and inadequate.

Die vorliegende Erfindung hat eine Verbesserung der bekannten Ausführung zum Ziel und zeichnet sich dadurch aus, daß der Ball mit der Schale durch einen Ballüberzug fest verbunden ist, welcher den Rand der Schale übergreift und unterhalb desselben formschlüssig festgelegt ist. Der Überzug besteht vorzugsweise aus Leder und ist vorteilhaft mittels Reißverschlüssen öffenbar, so daß er am Ball auf einfache Weise, aber sicher befestigt werden kann und diesen mit der Schale gut verbindet. Der Ball ist infolge der erfindungsgemäßen Ausbildung ausreichend verformbar, aber dennoch mit der Schale fest verbunden. Vorzugsweise ist an dem Untergestell ein Paar von Rückenstützen montiert, die sich über den Ball nach oben erstrecken.The present invention has an improvement on the known one Execution to the goal and is characterized in that the ball is firmly connected to the shell by a ball cover is, which overlaps the edge of the bowl and below it is form-fitting. The coating is preferably made made of leather and is advantageous by means of zippers openable so that he can easily but on the ball can be securely attached and connects it well to the shell. The ball is due to the training according to the invention sufficiently deformable, but still firmly attached to the shell. Preferably there is a pair of Backrests mounted, which extend upwards over the ball.

Die vorliegende Erfindung schafft damit einen höhenverstellbaren Stuhl, der es dem Benützer ermöglicht, die Beckenlage in der Sitzhaltung jener des stehenden Menschen anzugleichen, wobei die Wirbelsäule automatisch in die richtige Lage gebracht und der Muskelapparat aktiviert wird. Zugleich werden Hüftgelenke und Bandscheiben nicht überbelastet und der Oberkörper ausbalanciert.The present invention thus creates a height adjustable Chair that enables the user to position the pool to adjust in the sitting position to that of the standing person, with the spine automatically in the correct position brought and the muscular system is activated. At the same time Hip joints and intervertebral discs are not overloaded and the upper body balanced.

Für die richtige Sitzhaltung ist die Größe des Balles so gewählt, daß er im wesentlichen das Wurzelquadrat (d.h. jenes Quadrat, welches durch Steißbein, Sitzknochen und Schambein gebildet wird) unterstützt. Der Winkel zwischen Rumpf und Oberschenkeln kann so weit geöffnet werden, daß die Position der des stehenden Menschen entspricht. Somit bleibt das Becken in waagrechter Haltung, es kippt weder nach vorne oder hinten.For the correct sitting posture, the size of the ball is like this chosen to be essentially the square root (i.e. that Square, which is formed by coccyx, ischium and pubis is supported. The angle between the trunk and thighs can be opened so far that the position of the of the standing man. So the pelvis stays in horizontal position, it does not tip forward or back.

Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen näher erläutert, die schematisch zwei Ausführungsformen des Stuhles gemäß der Erfindung darstellen. Es zeigen:

  • Fig. 5 eine Vorderansicht und
  • Fig. 6 eine Draufsicht des Stuhles nach Fig. 4, die entweder gemäß den Fig. 1 bis 3 ohne Rollen oder gemäß den Fig. 4 bis 6 mit Rollen versehen sind und außerdem gemäß Fig. 2 durch einen Hebel 1'' höhenverstellbar sein können.
  • The invention is explained in more detail below with reference to the drawings, which schematically represent two embodiments of the chair according to the invention. Show it:
  • 1 is a side view of a chair according to the invention,
  • Fig. 2 is a front view and
  • 3 is a plan view of the chair of FIG. 1,

  • Die Untergestelle U nach den Fig. 1 bis 6 weisen alle eine Mittelsäule 1 auf, mit welcher eine Schale 2, die einen Ball 3 bettet, fest verbunden ist. Die Verbindung wird hergestellt durch ein genau auf die Mittelsäule passendes Rohr 1', welches an der Schale 2 angeschweißt ist, so daß eine stabile Verbindung gewährleistet ist.The bases U according to FIGS. 1 to 6 all have one Center column 1, with which a shell 2, the ball 3 bed, is firmly connected. The connection is established through a pipe 1 'which fits exactly onto the center column and which is welded to the shell 2, so that a stable connection is guaranteed.

    Zur Fixierung des Balles 3 in der Schale 2 ist ein Überzug 4 vorgesehen, welcher den Rand der Schale formschlüssig übergreift und beispielsweise mittels nicht gezeigter Reiß- oder Klettverschlüsse auf den Ball und die Schale aufgebracht wird. Der Ball 3 ist eine straff mit Luft gefüllte, mit einem Ventil verschlossene Kunststoffblase.A cover is used to fix the ball 3 in the bowl 2 4 provided which positively engages over the edge of the shell and for example by means of tear or not shown Velcro straps are applied to the ball and the shell. The ball 3 is a tightly filled with air, with a valve sealed plastic bladder.
