Abstract
A driving apparatus for an object which can be moved to and fro such as a te wing, comprising a guide block movable along a guide rail (1), said guide block being coupled to the object and to a driving member (2,2') movable by a motor and, with the aim of easy assemblage from only a small number of easily manufacturable components, consisting of a guide block component (3), having slidably supported thereon an actuating member (7), and of a manually actuated coupling member (5) spring-loaded towards the coupled position with the driving member, the actuating member (7) being in operative connection with the coupling member (5) through a bolt (8) stationary with said one member (7) and engaging at a sliding edge construction (9) formed in said other member (5) so that, when the actuating member (7) is displaced, the coupling member is brought against the direction of force of the spring acting thereon from the coupled position in the uncoupled position and automatically held in an end portion of the sliding edge construction in a rest position, while any displacement of the actuating member in the opposite direction will bring the coupling member under relief of the spring from the …
