Mechanism for securing and activating closures with guidable and removable slats

摘要

The closure has a slat translation operator formed by endless screws (1) with helices. The screws are located in sides of an opening to be covered and shifted into a synchronized shape. Hooking devices (3) e.g. nuts, are screwed into the screws and supported in helices by cylindrical bearings or ball grips so as to permit variation of a pitch (2) of the screws. A pinion is placed in an axis of a support piece of slats for rotating the slats. An independent claim is also included for a mechanism for securing and activating guidable and removable slat closures.
