Patent ID: 10862188

Abstract:
A positioning device includes a chassis, a plate to be positioned, wherein it further comprises a motor comprising a stator which is connected to the chassis and a rotor, a shaft which is connected to the rotor driven by the motor, which is mobile in rotation relative to the chassis in a first direction and in a second direction opposing the first direction, a first element for the transmission of rotational movement which is configured to be driven in rotation by the shaft in the first direction and to be free in the second direction, a second element for the transmission of rotational movement which is configured to be driven in rotation by the shaft in the second direction and to be free in the first direction, a first connecting rod which is connected to the plate by a first pivot connection and which is connected to the first element for the transmission of rotational movement by a second pivot connection which is offset to the axis of rotation of the first element for the transmission of rotational movement, a second connecting rod which is connected to the plate by a third pivot connection and which is connected to the second element for the transmission of rotational movement by a fourth pivot connection which is offset to the axis of rotation of the second element for the transmission of rotational movement, a connecting element having at least two degrees of rotational freedom between the plate and the chassis.
