| 摘要 |
The invention relates to a coupling mechanism (88), in particular for at least two relatively adjustable parts, each of which is provided with at least one coupling element (65, 72), and the coupling elements (65, 72) are provided with coupling parts standing slightly proud of a bearing surface (53, 54) of the parts receiving them and can be brought into engagement with one another, the coupling parts being of an elastically flexible, reversible design and being designed so as to locate with one another in certain regions in each of their relative positions in order to releasably fix the positioned parts. The parts (89; 90) can be pressurised in order to transmit force in the direction parallel with the bearing surface (53; 54) and are disposed so as to be relatively displaceable by means of an adjusting device (50; 51) for engaging or disengaging the locatable coupling elements (65, 72) at least at an angle relative to the bearing surface (53; 54), in particular perpendicular to the bearing surface (53; 54).
