Blind tilt assembly and method of controlling tilt ladders |
摘要 |
A tilt assembly for a blind including a first tilt ring and a second tilt ring, both rotatable about a drive axis for supporting a pair of tilt ladders, an input connector rotatable about the drive axis and configured to receive a drive shaft for rotating a lift spool and the input connector, a secondary input mechanism rotatable about the drive axis and configured to receive the drive shaft for rotating the secondary input mechanism with the input connector, a main clutch mechanism for releasably connecting the first tilt ring to the input connector and configured to release connection at each of two opposite rotational orientations of the first tilt ring, and a secondary clutch mechanism for releasably connecting the second tilt ring to the secondary input mechanism and configured to release connection at each of two opposite rotational orientations of the second tilt ring. |

1. A tilt assembly for a blind comprising:
a first tilt ring and a second tilt ring, both rotatable about a drive axis for supporting a pair of tilt ladders; an input connector rotatable about the drive axis and configured to receive a drive shaft for rotating a lift spool and the input connector; a main clutch mechanism for releasably connecting the first tilt ring to the input connector and configured to release connection at each of two opposite rotational orientations of the first tilt ring; an input mechanism rotatable about the drive axis and configured to rotate with the input connector; and a secondary clutch mechanism for releasably connecting the second tilt ring to the input mechanism; wherein: with rotation of the drive shaft for rotating a lift spool, the input connector is configured to rotate the first tilt ring to one of the two opposite rotational orientations and then continue to rotate when released by the main clutch mechanism, and the input mechanism is configured to rotate the second tilt ring to one of the two opposite rotational orientations and then continue to rotate when released by the secondary clutch mechanism; and the input mechanism is configured to rotate the second tilt ring with a delay after the first tilt ring has begun to rotate. |
