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.

A smart window/door opening-closing device that can easily be installed for use with an existing door or window or can be built-in by the door or window manufacturer, can be programmed to activate the opening or closing of the door or window either (a) remotely, (b) automatically by a pet and/or (c) automatically by a voice command, is easily disengaged when use is not desired, provides safety and security to prevent unwanted opening or closing of the door or window, and is integrated with a wireless communication network to enable smart and remote control of the window/door actuator.

A device for covering at least part of a container using a tarpaulin. The device includes a rod to deploy the tarpaulin across the container and an actuator. An arm extends between the actuator and the rod to allow the actuator to rotate the rod, the arm having an arm first end coupled to the rod and an opposed arm second end. The rod is coupled to the container so that the rod second end is movable relative to the container.

A locking device includes a cam that is formed in a rotating unit configured to rotate about a rotational center axis that is parallel to an opening width direction of a door, and the cam permits or prohibits movement of a door leaf in the opening width direction in accordance with a rotational position of the rotating unit.

A casement window operator, including: a first arm; a second arm, the first arm and the second arm each being rotatably mounted to the casement window operator and the first arm and the second arm each having a toothed peripheral portion for meshingly engaging a worm rotatably received in the casement window operator, such that rotation of the worm about its axis of rotation will cause the first arm and the second arm to rotate with respect to the casement window operator; and a damper located between the worm and a housing of the casement window operator, wherein the damper has a pair of anti-rotation features each being located about an exterior peripheral portion of the damper, the pair of anti-rotation features extending outwardly from the exterior peripheral portion of the damper and wherein the pair of anti-rotation features are configured to be received within a corresponding pair of openings of the housing of the casement window operator.
