| (54) | End of stroke device for rolling shutter operators |
| (57) This invention concerns an end of stroke device for rolling shutter operators, comprising
two cursors each associated with an end of stroke switch and both coupled to a threaded
bar turning in response to the rotation of a roller pulley. Each cursor (18, 19) is
assembled and turning idle between two support flanges, sliding on linear guides parallel
to the threaded bar, and it is engaged by a stop means (24) which is manually moveable
between a block position to prevent the cursor from turning and an unblocked position
to enable manual idle turning of the cursor in respect to the threaded bar for positioning
along said bar and in relation to the respective switch.
