Classification: CPC B  F | IPC B  F

Claim 0:
1. A joint device, with a first joint body and with a second joint body which whilst carrying out a working pivoting movement is pivotable about a pivoting centre with respect to the first joint body and positionable in different working pivoting positions,
wherein the first joint body defines a ball socket and the second joint body comprises a joint ball, wherein the joint ball is mounted in the ball socket rotatably about the pivoting centre for permitting the working pivoting movement of the second joint body and wherein the second joint body has an imaginary main axis which intersects the pivoting centre in each working pivoting position,
wherein two rotatable first and second drive units are arranged on the first joint body, wherein the first drive unit can be driven into a first drive rotation movement about a first rotation axis by way of introducing a drive force into a first actuation section and wherein the second drive unit can be driven into a second drive rotation movement about a second rotation axis which is aligned at an angle with respect to the first rotation axis, by way of introducing a drive force into a second actuation section,
wherein the first drive unit comprises a first drive gearwheel with a first drive gear rim which lies in a first gear rim plane which extends transversely to the first rotation axis and wherein the second drive unit comprises a second drive gearwheel with a second drive gear rim which lies in a second gear rim plane which extends transversely to the second rotation axis,
wherein the joint ball of the second joint body comprises a driven toothing, with which the drive gear rims of the two drive units are in toothing engagement, in order to permit a force transmission which causes the working pivoting movement, and
wherein the joint ball is designed as a hollow ball which encompasses a ball interior and which has a concavely curved inner peripheral surface, on which the driven toothing is formed as an inner toothing, wherein the two drive gearwheels are in toothing engagement with the driven toothing in the ball interior and wherein the two drive units can be driven independently of one another individually or simultaneously into their respective drive rotation moment for creating the working pivoting movement of the second joint body.
