Abstract: A table is provided which has variable dimensions, especially a long length, and is mainly used in offices and conferences. The base of the table is supported by feet (6) and carries table leaves (1,1) which are brought together at the longitudinal sides thereof, and an insert (8,81) which can be inserted in-between the leaves, can have different configurations and can be used as a support for various structures. The base of the table includes at least two transversal supports (2) provided with a central sunken channel region (20) from which two extension arms (21) respectively extended in opposite directions, the feet (6) being mounted on the arms, and lateral struts (4) supporting the table leaves (1,1) being arranged on the outside.

Abstract: The chair has a sub frame (1) set on the floor, a mechanism (2) set on the sub frame, a seat (3) set on the mechanism (2) and a backrest (7) attached to the mechanism (2). The backrest (7) exhibits a backrest frame (5), which supports an elastically deformable backrest part (6) with a back panel (62). The back panel (62) has a back part (60), to which a head restraint (61) is attached. The backrest (7) is capable of pivoting about a first pivot shaft (D1) from an essentially upright, neutral position to a reclined position displaced towards the rear. The movements of the seat (3) and the backrest (7) are synchronized with one another.

Abstract: The adjustment mechanism contains a pneumatic spring that is placed vertically in the underframe, for adjusting height, and a pneumatic spring that is linked to the seat support at one end and the back-rest at the other, for synchronized adjustment of the angle. The pivotable back-rest and the fixed seat support are coupled with each other on the main rotational axis in two hinge connections. The main rotational axis runs above and crosswise over the seat plate. The seat plate has guide cranks on its underside, the supporting arms of the seat support engaging is said guide cranks in such a way that they can slide crosswise to the main rotational axis. The front bearing pegs of the supporting arms engage in the guide cranks. The seat plate is coupled together with the inclination spring on the moving rotational axis on the back-rest. The invention also relates to a back cover with a variably positionable lumbar reinforcement insert and height-adjustable armrests.

Abstract: The chair mechanism is configured as a so-called synchronizing mechanism in order, in the case of an adjustment in inclination of the rear support (4), to achieve simultaneous, harmonic adjustment of the seat panel (8). The underframe is positioned on a height-adjustable pneumatic spring (13,14). For the synchronized movement, use is made of a mechanical torsion spring, preferably a rubber spring, and a further mechanical spring, preferably a helical spring, is arranged parallel thereto, with accumulative effect in relation to the resistance of the torsion spring. The strength of the torsion spring can be adjusted. The positioning of the axes of rotation (A1-A4) is of considerable importance for the kinematics. The chair can be adjusted from an assembly position, where the springs can be inserted in a state in which they are relieved of stressing, via the vertical position into the inclined position.

Abstract: Movable office furniture consisting of the following system components: a travelling table (1), a filing trolley (1) a cupboard, an equipment box and a shelf partition (7). Said office furniture can be used in permanent company offices, at exhibitions, conferences or in the home. The tables have no cross tie-bars close to the ground between legs. At least one interchangeable box (100) can be inserted into the various types of trolleys (4). Many of such boxes can be inserted into cupboards. Shelves can be installed on shelf partitions (7) and office equipment and stationery can be stored thereon. Shelf partitions (7) can be placed back to back to form a double wall in a room and have the advantage of being produced from sound absorbing material. The office furniture can be spontaneously rearranged and several components of the system are interslidable in order to gain space.
