Selectable opening flap for electronics casing

摘要

The casing (1) has a flap (3) pivoted on an axis (R) to different angular positions. A flexible arm (23) fixed to the casing has a pin (27) which extends perpendicular to the axis of rotation (R). Recesses are spaced around a rounded edge ( and ) on the flap to receive the pin. The flexible arm exerts a radial pressure on the rounded edge (7) via the pin.
