The table comprises a plate (30) and a rod support with two bar parts (21,29) and two articulations (14). The primary articulation is pivotable in relation to a fixture (10) around a horizontal shaft (16). The pivoting movement is restricted by a pin (18) in an arc-shaped track (17). A first bar (21) is fitted in the first articulation and locked in a height direction by a clamp (22,23). The secondary articulation is provided with fixtures (27,28) for the bar parts. The first bar part can be rigidly fitted in its fixture (27), whilst the fixture (28) for the second part (29) permits easy adaption, but can be drawn out with the aid of a screw andwheel (31). The first bar part has limited pivotable relation to the fixture and may be adjusted in its height direction, but cannot be turned relative to its articulation around the shaft. |
