Abstract

A device for opening a door includes an electric motor on a base, a slider movable relative to the base along a rectilinear direction between a rest position and an open position, and a rod pushing against the door and movable relative to the base and the slider along the rectilinear direction between a retracted position and an extracted position. An actuating element resiliently pushes the rod towards the extracted position. A gearwheel transmission is arranged between the electric motor and a transmission device to cause movement of the slider into the open position. The gearwheel transmission includes a gearwheel having a non-toothed segment which disengages the slider from the electric motor when the slider reaches the open position. A recall element recalls the slider towards the rest position or the rod towards the retracted position when the non-toothed segment disengages the slider from the electric motor.
