Description

The invention relates to a chair with a chair column and one both its longitudinal and its transverse axis, i. forward and backward as well as to the side, against the restoring force of at least one elastically deformable element pivotable, mounted on a coupling element seat element.

Such chairs are described inter alia in the EP 2 486 826 B1 , of the EP 1 584 266 B1 and the DE 102 45 774 A1 ,

In these known chairs elastic elements between stored in the rest position of the chair substantially horizontally oriented support plates. The known chairs are relatively expensive in terms of design as well as during assembly of the coupling element.

The invention has for its object to provide a contrast structurally simpler chair, the assembly is simplified compared to the known chairs.

• – das Kopplungselement ein Stützelement mit einer Außenfläche mit kugelförmig ausgebildeten Abschnitten aufweist,
• – das Stützelement zwei entlang einer ersten Achse ausgerichtete Achszapfen und zwei weitere Achszapfen enthält, die entlang einer die erste Achse rechtwinklig schneidenden zweiten Achse ausgerichtet sind,
• – das Stützelement und die Achszapfen verschwenkbar in zwei sich gegenüberliegenden Halbschalen, die jeweils halbkugelförmig gestaltete Innenflächen aufweisen, gelagert ist, und
• – die Achszapfen unter Zwischenschaltung von elastischen Elementen als Achslager in den beiden Halbschalen gelagert sind.

To solve this problem, the chair according to the invention is characterized in that

• The coupling element has a support element with an outer surface with spherically formed sections,
• The supporting element comprises two axle journals aligned along a first axis and two further axle journals which are aligned along a second axis which intersects the first axis at right angles,
• - The support member and the axle pivotally in two opposite half-shells, each having hemispherically shaped inner surfaces, is mounted, and
• - The journals are mounted with the interposition of elastic elements as axle bearings in the two half-shells.

Preferred embodiments of the invention are dealt with in the subclaims.

The consisting of two half-shells coupling element consisting of two half-shells forming a unit and the particular spherical support elements mounted between them, can be mounted in a particularly simple manner between the chair column and the seat element or a seat element substructure, if the two half-shells one unit forming with enclosed therein support element rigidly secured together or connected to each other.

The invention will be described in more detail below with reference to the drawing:

1 shows a simplified schematic representation of the front view of a chair;

the 2 and 3 show the in 1 illustrated chair structure in laterally pivoted positions;

4 shows an exploded view in a schematic perspective view of the coupling element used in the invention;

5 shows a chair in unloaded condition;

6 shows the in 5 shown chair in a forward pivoted position of the seat element.

In the figures, the seat element 1 , the backrest 1' and the chair column 9 with the seat element 1 connecting coupling element 2 shown in a simplified, schematic representation.

• – eine untere Halbschale 6,
• – eine obere Halbschale 7 sowie als Stützelement
• – eine zwischen den beiden Halbschalen 6 und 7 gelagerte Kugel 3 mit
• – entlang einer ersten X-Achse ausgerichteten Achszapfen 4 sowie
• – zwei weitere Achszapfen 5, die entlang der Y-Achse ausgerichtet ist, die zur X-Achse der beiden Achszapfen 4 senkrecht ausgerichtet ist, sowie
• – in die Halbschalen 6 und 7 eingesetzte elastische Elemente 8 bzw. 8’, die Achslager für die Achszapfen 4 und 5 bilden.

The coupling element 2 contains in particular in 4 shown way the following individual elements

• - a lower half shell 6 .
• - an upper half shell 7 as well as a support element
• - one between the two half-shells 6 and 7 stored ball 3 With
• - Aligned along a first X-axis journals 4 such as
• - two more axle journals 5 , which is aligned along the Y-axis, to the X-axis of the two journals 4 is oriented vertically, as well
• - in the half-shells 6 and 7 used elastic elements 8th respectively. 8th' , the axle bearings for the axle journal 4 and 5 form.

In 4 is the chair column 9 shown in dashed lines, at its upper end a conventional gas spring 10 wearing. The chair column 6 is with the gas spring 6 ' in an axially aligned opening of the ball 3 used.

The ball 3 with their axle journals 4 is rigid with the chair column 9 or the gas spring 10 connected. In a weight shift of a person sitting on the seat element, the two become one unit forming half-shells 6 and 7 with the elastic elements 8th and 8th' around the stub axles 4 and / or the stub axle 5 pivoted, in each case against the restoring force of the elastic, preferably made of an elastomeric material elements 8th and 8th' in the in the 2 and 3 such as 6 shown positions in which the seat 1 relative to the chair column 9 be pivoted.

The spherical support element shown in the drawings 3 can also be divided into individual ball sections, with the alignment and attachment of the journals 4 and 5 in the in 4 way shown remains unchanged.

Between the upper half shell 7 and the seat element 1 may be a so-called synchronous mechanism unit for simultaneous displacement of the seat member in a substantially horizontal direction in response to the pivotal movement of the seat back 1' be attached to the seat element 1 and the synchronizing mechanism unit is coupled.
