Abstract:
An articulated joint for fastening a first movement element which, by means of the articulated joint, is movably coupled to a second movement element, comprising:a fastening unit which has at least one first and one second braking element, the first braking element being connected to the first movement element and the second braking element being connected to the second movement element, the braking elements being able, by the action of a force generated by a force-application element, to be engaged with one another in such a manner that they are fastened to one another, such that the movement elements are also fastened to one another via the connection of the braking elements to the movement elements, a mechanical switching unit characterized in that the mechanical switching unit can take up a coupling state and at least one separating state, wherein the switching unit switches over from the coupling state into the separating state when the movement elements move relative to one another, and wherein, in the coupling state, the switching unit activates the force on the braking elements, so that the braking elements enter into engagement with one another, and wherein the switching unit further comprises a first and second actuating element, wherein the first actuating element is connected to the first movement element and the second actuating element is connected to the second movement element in such a manner that the movement of the movement elements causes a rotational movement of the actuating elements which are mounted on one another in such a manner that when there is a relative movement between them, they execute a switching movement taking place in a direction which is parallel to the axis of rotation such that the actuating elements move apart from each other, causing the switching unit to switch over from the coupling state into the separating state, in which the action of the force on the braking elements is overcome, so that the braking elements become detached from one another, and at least one coupling element that converts the relative movement of the movement elements into a switching movement of the actuating elements, and whereby, in the coupling state, the coupling element activates the force on the braking elements, so that the braking elements enter into engagement with one another.
