Sliding operator assemblies and associated fenestration units, systems, and methods of use and assembly are described. Some such sliding operator assemblies transition a first, linear actuation force along a first axis (e.g., vertical) to a second actuation force along a second axis (e.g., horizontal) to cause a drive mechanism to impart opening and closing forces, respectively, on the sash. Some designs relate to belt-, twisted ribbon-, or band-drive sliding operator assemblies.

An actuating apparatus for a flap which is mounted on a component for movement has a first actuating element, fastenable fixedly to the flap so as to rotate with it, and a second actuating element, fastenable to the component, and rotatable about a first rotational axis, the second actuating element has a first end and a second end, the first end configured to interact with a drive, the second end has a first locking or release geometry, the first actuating element has a second locking or release geometry, the second actuating element can be rotated between a first orientation and a second orientation, wherein the first and second locking or release geometry are configured to interact such that, in the first orientation, the first actuating element is locked to the second actuating element and, in the second orientation, the first actuating element is released from the second actuating element.

The method of door control without, hand contact, wherein, when the door leaf is in its stationary closed position, all the energy necessary for automatic opening and subsequent closing the door leaf, initiated by an actuating force, preferably realized by means of a foot lever, is accumulated in an opening and closing mechanism during the actuating action of the controlling mechanism. During the automatic opening, the only acting force is the tension of the opening member, and during the subsequent automatic closing, the only acting force is the tension of the closing member. By means of the bimodal opening and closing mechanism, the tensions of these two members act separately, not against each other.

A closing aid for a luggage compartment flap is described, which closing aid comprises an actuating element, a movement element and a connecting element. The actuating element is integrated in a locking mechanism of the luggage compartment flap. The connecting element connects the actuating element to the movement element and transmits a movement of the actuating element to the movement element such that the luggage compartment flap fastened to the movement element is moved at least part of the way from an open position to a closed position. A luggage compartment and a vehicle having a closing aid of this type are also described.

An indoor maintenance cover of a bus includes: a frame mounted on a maintenance hole; a first door and a second door in which respective both ends are connected to the frame by a hinge pin to open/close the maintenance hole; an interlocking device configured to join a hinge pin connected to one end of the first door and a hinge pin connected to one end of the second door, the interlocking device facing the hinge pin so that the first door and the second door rotate while interlocking with each other; and a fastener fastening the first door and the second door while the first door and the second door are closed. The maintenance cover can be installed to prevent accidents while increasing operability for easily opening or closing the maintenance hole in the bus.

A covering for an architectural opening has a dual cord operating system. The covering may include a head rail, blind panels depending from the head rail, and an operating system. The operating system may include a housing connected to the head rail, a first drive assembly rotatably mounted within the housing and operable to move the blind panels between an extended configuration and a retracted configuration, and a second drive assembly rotatably mounted within the housing and operable to move the blind panels between a closed configuration and an open configuration.
