LEVER LOCKING DEVICE Russian patent published in 2021 - IPC B64G1/64 

FIELD: space industry.

SUBSTANCE: invention relates to activating mechanisms of devices for holding and releasing movable structural elements of spacecraft. Lever locking device contains a tightening element (9) that engages the axis (13) of the fixed element (12) when interacting with the levers (3) and (5). The lever (3) is loaded by the spring (7) through the pivot links (4₁, 4₂) on the axles (6₁, 6₂, 6₃) and is fixed in the initial state by the roller (10) of the supplementary lever (5). The lever (3) has an axis of rotation (11), and the lever (5) has an axis of rotation (14). When the fixed elements (8) and (12) approach each other, the tightening element (9) rotates the lever (5), releasing the lever (3), which rotates under the action of the spring (7) and comes into contact with the element (9), bringing it into engagement with axis (13). At the end of the lever stroke (3), the moment of impact on it sharply increases, because links (4₁, 4₂) are straightened in line. In this state, the links (4₁, 4₂) fix the lever (3).

EFFECT: improved performance and reliability of the device.
