Claims (4)
1. Safety and arming device for fuses in launchable missiles/ comprising a rotatable shutter actuated by a spring tending to rotate the shutter from a safety positon to an arming position, said shutter being blocked against rotation by blocking means (28) which are movable from their blocking position upon a rotating movement of a countershaft f) which is releasably coupled to the shaft of a turbine wheel driven by ram air, said. shaft extending in the axial direction of the shutter, characterized in that the countershaft is displaced axially due to its rotation, that the shutter J f is blocked by blocking means z ) which are permitted to leave their blocking position as a consequence of an axial displacement of the countershaft ^fr in the axial direction of the shutter j( "T, and that there is provided an acceleration or shock safety (1.5 to■-?¾.) which in addition to directly securing the shutter J f also holds a blocking element in engagement with the countershaft ^ in order to block said shaft against axial displacement.
2. Device according to claLm 1, characterized in that the blocking means are positioned in throughgoing apertures in a stationary sleeve between the shutter &) and the countershaft J&l and extend into . axial grooves (^&) in the shutter J^J" .
3. Device according to claim 1 or 2, characterized in that the blocking element 2iTj of the acceleration or shock safety in its blocking position extends perpendicularly to the countershaft {frf into a peripheral groove therein.
4. Device according to claims 2 and 3, characterized in that the blocking means are positioned rearwardly of the blocking element of the acceleration or shock safety when viewed in the direction of displacement of the countershaft, and are permitted to move into said peripheral groove in the countershaft Jft in order to release the blocking of the shutter when the countershaft jC-fJ has been moved rearwards.
