Abstract: The table is provided with vertical cheek elements (13) provided with arcuate guiding paths (15). Arcuate rods (16,17) glide within these guiding paths (15), their upper ends being pivotably connected with the board (14). One hinge (19) is a moveable hinge that allows to vary the distance between both hinges (18,19) corresponding to the position of the rods (16,17). If only one of the two rods (16,17) is shifted in its guiding path (15), the inclination of the board (14) will be changed. If this rod is subsequently fixed and the other rod is shifted, the board may be fixed on another level parallel to the first position. The table allows optional inclinations and changes of height of the board (14).
