<p>The first table plate (3) is pivotably located on a rail segment (9) close to the second plate (5). The rail segment forms part of a parallel arm system (19, 3, 9, 7), and the second table plate rests against the rail segment. The height of the first plate is such that the second plate is at a height suitable for work in a standing position when the first plate is pivoted upwards through 90 deg. In this position, the second plate is horizontal, and it can also be pivoted upwards and locked in a position in which it constitutes an extension of the first plate.</p> |
