Spool housing for a window covering

1. A spool housing for a window covering, comprising

a housing wall defining an interior and an exterior;

an inlet nozzle extending outwardly from said housing wall along its exterior, said inlet nozzle including a nozzle wall defining an opening for receiving a cord, at least a portion of said nozzle wall extending from a proximal end closest to said housing wall and terminating at a distal end further away from said housing wall; and

a spool housed in the interior of said housing wall for winding up the cord and having an axis of rotation;

wherein:

said inlet nozzle includes a collection trough wall defining a portion of said opening;

said collection trough wall extends away from said distal end of said nozzle wall by a distance such that an outer edge of said collection trough wall is spaced farther apart from said axis of rotation than said distal end of said nozzle wall; and

said collection trough wall defines an open face relative to said nozzle wall to permit said cord to be pushed against said collection trough wall from a direction perpendicular to an axis of said opening.

2. A spool housing for a window covering as recited in claim 1 , wherein at least one edge of said collection trough wall is radiused inwardly.

3. A spool housing for a window covering as recited in claim 1 , wherein:

said opening is a first opening and said cord is a first cord;

said inlet nozzle defines a second opening for receiving a second cord; and

said second opening is positioned adjacent to said first opening.

4. A spool housing for a window covering as recited in claim 3 , wherein said collection trough wall forms a common wall between said first opening and said second opening.

5. A spool housing for a window covering as recited in claim 3 , wherein:

said axis of said first opening corresponds to a first axis and extends perpendicular to said axis of rotation; and

said second opening defined a second axis extending parallel to said first axis.

6. A spool housing for a window covering as recited in claim 5 , wherein said collection trough wall extends lengthwise along a trough axis which is parallel to said first and second axes.

7. A spool housing for a window covering as recited in claimy 3 , wherein:

said collection trough wall is a first collection trough wall; and

said inlet nozzle includes a second collection trough wall that extends away from said outer edge of said first collection trough wall such that a second outer edge of said second collection trough wall is spaced farther apart from said axis of rotation than said outer edge said first collection trough wall.

8. A spool housing for a window covering as recited in claim 7 , wherein said second collection trough wall extends lengthwise along a second trough axis which is parallel to a second axis defined by said second opening.

9. A spool housing for a window covering as recited in claim 7 , wherein at least one of said first collection trough wall or said second collection trough wall has a partial cylindrical shape.

10. A spool housing for a window covering as recited in claim 7 , wherein said second opening is defined directly between said first collection trough wall and said second collection trough wall.

11. A spool housing for a window covering as recited in claim 7 , wherein at least one of said first collection trough wall or said second collection trough wall is substantially U-shaped.

12. A spool housing for a window covering, comprising

a housing wall defining an interior and an exterior;

an inlet nozzle extending outwardly from said housing wall along its exterior, said inlet nozzle including a nozzle wall at least partially defining an opening for receiving a cord, at least a portion of said nozzle wall extending from a proximal end closest to said housing wall and terminating at a distal end further away from said housing wall; and

a spool housed in the interior of said housing wall for winding up the cord and having an axis of rotation; wherein:

said inlet nozzle includes a collection trough wall defining a portion of said opening;

said collection trough wall extends away from said distal end of said nozzle wall; and

said nozzle wall is tapered outwardly in a direction away from said axis of rotation such that a diameter of said opening at said distal end of said nozzle wall is larger than a diameter of said opening at said proximal end of said nozzle wall.

13. A spool housing for a window covering as recited in claim 12 , wherein at least a portion of said opening is defined directIv between said nozzle wall and said collection tough wall.

14. A spool housing for a window covering as recited in claim 12 , wherein al least one edge of said colleclioii trough wall is rodiused inwardly.

15. A spool housing for a window covering as recited in claim 12 , wherein:

said opening is a first opening and said cord is a first cord;

said inlet nozzle defines a second opening for receiving a second cord; and

said second opening is positioned adjacent to said first opening.

16. A spool housing for a window covering as recited in claim 15 , wherein said first opening defines a first axis extending perpendicular to said axis of rotation and said second opening defines a second axis extending parallel to said first axis of said first opening.

17. A spool housing for a window covering as recited in claim 16 , wherein said collection trough wall extends lengthwise along a trough axis which is parallel to said first and second axes.

18. A spool housing for a window covering as recited in claim 15 , wherein said collection trough wall forms a common wall between said first opening and said second opening.

19. A spool housing for a window covering as recited in claim 15 , wherein:

said collection trough wall is a first collection trough wall; and

said inlet nozzle includes a second collection trough wall that extends away from an outer edge said first collection trough wall such that a second outer edge of said second collection trough wall is spaced farther apart from said axis of rotation than said outer edge of said first collection trough wall.

20. A spool housing for a window covering as recited in claim 19 , wherein said second collection trough wall-extends lengthwise along a second trough axis which is parallel to a second axis defined by said second opening.

21. A spool housing for a window covering as recited in claim 19 , wherein at least one of said first collection trough wall or said second collection trough wall has a partial cylindrical shape.

22. A spool housing for a window covering as recited in claim 19 , wherein at least one of said first collection trough wall or said second collection trough wall is substantially U-shaped.
