Abstract: An office furniture piece combination of a plurality of pieces of office furniture, in particular office desks. A frame with a uniform cross piece has lateral legs which can be connected with each other by a non-free-standing coupling elements using bolts and receivers. A simple, rigid connection between the cross pieces of adjacent office furniture pieces and the coupling element, which can be made and released without tools, is achieved with receivers positioned into the front faces of the cross pieces. The exterior cross section of the coupling elements are essentially adapted to the exterior cross section of the cross pieces and support rotatably seated locking bolts which are oriented towards the receivers of the cross pieces. The coupling elements have a preset, identical dimension in the longitudinal direction of the cross pieces. The locking bolts extend from both front faces of the coupling elements with eccentric locking heads or clamping bolts.

Abstract: A work table or office desk with a work surface which is adjustable in height or inclination, and is supported by two pairs of pivotal support arms on the cross piece of a table support. One pair of support arms is oriented towards the front and the other pair of the support arms towards the back of the work surface. The support arms are hinged on sliders which are adjustable in guide rails extending from the front to the back, on the underside, of the work surface. A simple drive device, which can be integrated into the support arms, provides numerous possibilities for changing the height and/or inclination of the work surface.

Abstract: A table support for a work table or office desk having two lateral table legs, the upper ends of which are rigidly connected with each other with a cross piece and the lower ends of which have foot elements oriented towards the front and back of the work table or office desk. A simple structure with many add-on capabilities is achieved since the cross piece is formed by a tub-shaped sheet metal section which is open at the top, and the side walls of which are shaped as hollow sections. The side walls have connecting sections for fixing a cable channel cover on their interior side, facing each other. Connecting straps are inserted into both ends of the sheet metal section which, along with the side walls of sheet metal section and together with the base leg of the sheet metal section, are rigidly connected with the table legs. Insertion connectors are inserted into the ends of the side walls, which are formed as hollow sections, of the sheet metal section.
