Abstract: An adjustable table top (7, 105) is supported movably on a trestle having at least one abutment (5, 104) fixed thereto beneath the table top. The abutment coacts with a wedge-shaped intermediate piece (9, 106) which is displacable in an opening direction of its wedge angle, substantially parallel to the table top, and which can be introduced to a lesser or greater extent into a space between the abutment and the table top so that a distance between the table top and the abutment and, thus, the position of the table top relative to the trestle, are determined by the position of the intermediate piece.

Abstract: An office desk suited in particular for peripheral computer equipment consists of two side parts formed by columns provided with feet, a longitudinal beam detachably connected with the columns by connection elements establishing a form-locking connection, and of carrying arms for at least one table top mounted on the longitudinal beam. These components can be varied in many different ways and combined in the most different manners so that office desks optimally adapted in each case to the respective application can be realized with the same basic elements.
