Abstract: A table system including at least one primary module and at least two secondary modules. The primary module includes a tabletop plate and a plurality of crossbars disposed parallel to each other and secured to the underside of the tabletop plate. A secondary module comprises a table leg having an upper end and a plurality of interlocking and bracing mechanisms disposed at the upper end of the table leg. A primary module and a secondary module together have an attached state and an interconnected state. The interlocking and bracing mechanisms have an open state and a closed state. In the attached state, each interlocking and bracing mechanism is in the open state, and is achieved by vertically setting the primary module onto the secondary module. In the interconnected state, each interlocking and bracing mechanism is in the closed state, interlocked independently into the interior portion of a crossbar.

Abstract: The present invention relates to a table system with at least one tabletop plate (1) exhibiting a table underside and with at least two table legs (2). The table system comprises two distinct modules, wherein a primary module includes the tabletop plate (1) and two crossbars (3) interspaced with respect to each other and securely arranged on the underside of the table, and a secondary module includes the table leg (2) with at least two interlocking and bracing mechanisms (11), wherein at least one of the interlocking and bracing mechanisms (11) of the secondary module engages in each case into one of the crossbars (3) of the primary module, and said interlocking and bracing mechanism (11) operates according to the knuckle joint principle.

Abstract: The backrest of a chair comprises a frame, a backrest support and a neck support. A membrane is clipped into the frame, and the backrest support is articulated on a tilting mechanism. The frame comprises two side parts and two cross-pieces, the lower cross-piece lying at the height of the user's lumbar vertebra. The frame and the backrest support are interconnected in one piece. The component created as a result is advantageously a plastic injection molding produced by the gas injection technique (GIT) and the plastic is a glass-fiber-reinforced polyarylamide. This overall structure of the backrest provides a high level of sitting comfort by elastic support of the back in all major regions and directions of movement, but at the same time also considerably reduces production, transport and assembly complexity and has an aesthetically impressive, distinctive form.

Abstract: The backrest of a chair comprises a frame (1), a backrest support (6) and a neck support (15). A membrane is clipped into the frame (1), and the backrest support (6) is articulated on a tilting mechanism. The frame comprises two side parts (2, 3) and two cross-pieces (4, 5), the lower cross-piece (4) lying at the height of the user's lumbar vertebra. The frame (1) and the backrest support (6) are interconnected in one piece. The component created as a result, is advantageoulsly a plastic injection moulding produced by the gas injection technique (GIT), and the plastic is a glass-fibre-reinforced polyarylamide. This overall structure of the backrest provides a high level of sitting comfort by elastic support of the back in all major regions and directions of movement, but at the same time also considerably reduces production, transport and assembly complexity and has an aesthetically impressive, distinctive form.

Abstract: A movable table flap that which can be integrated into a work surface of a table, wherein in a closed position the upper side of the table flap is flush with the work surface of the table and a device for connecting various electric appliances and communication facilities is arranged underneath the table flap, wherein in the open position, the table flap can be both inclined and recessed simultaneously. The position of the table flap is changed by use of a compression spring, which is movable in an arched guide slot.

Abstract: A device for lumbar support for an office chair having a seatback including a seatback frame and a membrane stretched over the seatback frame. The device can be arranged behind the membrane and can be housed in the seatback frame to provide vertical and horizontal adjustment independent of the membrane. Preferably, the device includes a central part having two comparably rigid carrier elements connected to each other via an elastic element arranged therebetween, the rigid carrier elements each including a guide track that can be arranged in the seatback frame to provide the vertical adjustment. A front part includes a cushion attached to an upholstery plate, the upholstery plate facing the membrane. A rear part includes a plastic plate. The cushion and the plastic plate are connected via a clip connection, and the clip connection is guided in slots of the carrier elements.

Abstract: The invention relates to a moving table flap (1) that can be integrated into the work surface (4) of a table (2), wherein in the closed position the upper side (3) of the table flap (1) is flush with the work surface (4) of the table (2) and a device (6) for connecting various electric appliances and communication facilities is arranged underneath the table flap (1), characterised by the fact that in the open position the table flap (1) can be both inclined and recessed simultaneously. The position of the table flap (1) is changed by means of a compression spring (15), which is moved in an arched guide slot (14). The device (6) is easy to access and to operate.

Abstract: A nut or a pair of nuts connecting the inlet fitting or a pair of inlet fittings of a water-dispensing fixture to respective connecting fittings is axially aligned with a collar threaded onto each connecting fitting and bearing upon a wall from which the connecting fitting emerges. An apron is axially shiftable on the cylindrical surfaces of the nut and collar which are axially aligned and of the same diameter to completely cover the nut or nuts. The apron is held in place by an elastic member seated in the collar.
