HASP LOCK Russian patent published in 1997 - IPC

FIELD: shackle-lock production engineering. SUBSTANCE: hasp lock has arranged facing each other body and clamping plate with slots having central jumpers. Body has cylindrical lead for key and cross-bar made like unclosed ring installed for rotation. Cross-bar has moving-fixing mechanism mounted at guiding member, spring loaded fixing members and driver spring loaded with respect to cross-bar and connected with it movably by spline. Mechanism has possibility of rotary and longitudinal motion with respect to its main axis. External end of guiding member has circular L-shaped recess and flange with crimp and slots. Internal end has slots for cross-bar keeping from rotation by split using. Guiding member has radial holes with balls placed inside it and interacted with guide longitudinal slots and fixing members grooves. For unlocking action key has head made like two shoulder lever with recess interacting to guiding member edge and L-shaped overhang interacting with fixing members. Key unlocks hasp-lock by drive actuating through holes after cross-bar deblocking and disfixing. While key turning cross-bar turns too, and key is fixed in working position by its own protrusions matched with slots made at guiding member internal end to restrain working path. EFFECT: higher operation reliability and better protection from breaking open and break down. 4 dwg
