US Patent 10988969 Screening apparatus and assembly

Aspects of the present disclosure are directed to apparatuses and related methods involving a screening apparatus and assembly. As may be implemented in accordance with one or more embodiments, an apparatus includes a plurality of panels, a frame and, for each panel, a locking mechanism coupled to the frame and a mechanical actuator connected to the panel and the frame. The locking mechanism locks the panel in place when engaged with the panel, and may do so at a different angle of rotation, relative to the other panels. The mechanical actuator positions the panel relative to the frame and offset from the other panels, and facilitates rotation of the panel about an axis of rotation that is fixed relative to the frame, in response to the panel being disengaged from the locking mechanism.
