A drum is driven by cord ends, which are wrapped onto the drum. The drum sits in a housing with slotted openings which are opposite each other and in a plane which is substantially tangent to the surface of the drum. The cord ends exit the housing through said slotted openings such that, even if both ends of the cord are pulled at the same time, the force is directed so that it does not cause, or minimizes, deflection of the drum.
