| 摘要 |
The invention provides an articulated joint having a device for movably coupling a first movement element to a second movement element. The device comprises a fastening unit, which comprises at least one first braking element connected to the first movement element and at least one second braking element connected to the second movement element, a force application element which applies a force to at least one of the first or second braking elements, and a mechanical switching unit capable of taking up a coupling state and at least one separating state. The mechanical switching unit switches over from the coupling state into a separating state when the movement elements move relative to one another, and the mechanical switching unit deactivates the force applied by the force application element to at least one of the first or second braking elements when the mechanical switching unit is in the separating state. |
