Abstract

A unitary assembly for an architectural fenestration, providing dynamic solar heat gain control, which (1) provides a track-based frame structure/blind combination in which the blind is self-correcting should the blind material fall outside of the track; (2) provides directional shading, where the assembly provides for dynamically controlling the amount of light allowed to reach the heat storage unit; (3) provides a blind motor without limiter switches and with a quick-release slip-ring; and (4) provides a heat storage unit which is a thermally efficient, transparent and translucent structure, with which gain from sunny winter days is greater than nighttime loss, so as to provide supplemental heat.

First claim

We claim:

1. An assembly for covering an architectural opening, said assembly comprising:
a shade including a shade material, said shade material movable between a retracted position and an extended position;
a plurality of louvers coupled to and extending outwardly from said shade material, each of said louvers extending in the widthwise direction between a first side segment and a second side segment opposite said first side segment;
a frame positioned relative to the architectural opening, said frame defining a guide track configured to receive opposed side sections of said shade material as said shade material is moved between said retracted and extended positions, said guide track including a first side track and an opposed second side track, said first track configured to receive said first side segment of each of said louvers, and said second guide track configured to receive said second side segment of each of said louvers as said shade material is moved between the extended and retracted positions; and
a bottom rail coupled to a bottom end of said shade material, said bottom rail extending in the widthwise direction between a first end positioned adjacent to said first side track and a second end positioned adjacent to said second side track, said bottom rail including a first track guide extending from said first end into said first side track and a second track guide extending from said second end into said second side track;
wherein said first and second track guides are maintained within said first and second side tracks as said shade material is moved between said retracted and extended positions.

2. The assembly as in claim 1 , wherein, when said shade material is in said retracted position, said side sections of said shade material are positioned outside of said first and second side tracks while said first and second track guides are maintained in engagement with said first and second side tracks.

3. The assembly as in claim 1 , further comprising first and second guide plates positioned directly above said first and second side tracks, respectively, said first and second guide plates configured to maintain said shade material centered in a widthwise direction relative to said first and second side tracks.

4. The assembly as in claim 1 , wherein:
each of said louvers includes a first edge coupled to said shade material and a second edge opposite said first edge;
each of said louvers defines a louver depth between said first and second edges; and
said opposed side segments of each of said louvers are notched so that each side segment defines a notch depth that is less than said louver depth.

5. The assembly as in claim 4 , wherein said second edge is provided in a cantilevered arrangement relative to said shade material.

6. The assembly as in claim 1 , wherein said bottom rail defines a rail width between said first and second ends, said rail width being less than a track width defined between said first and second side tracks.

7. The assembly as in claim 6 , wherein said shade material defines a shade width, said shade width being greater than said rail width.

8. The assembly as in claim 1 , further comprising a transverse alignment guide positioned above said first and second side tracks, said transverse alignment guide configured to support an underside of said shade material as said shade material is moved between said retracted and extended positions.

9. The assembly as in claim 8 , wherein said transverse alignment guide defines a forward edge, said forward edge being vertically aligned with said first and second side tracks.

10. The assembly as in claim 9 , further comprising a roller about which said shade material is wound and unwound when said shade material is being moved between said retracted and extended positions, said roller defining a rotational axis that is offset laterally from said forward edge of said transverse alignment guide and said first and second side tracks.

11. An assembly for covering an architectural opening, said assembly comprising:
a shade including a shade material, said shade material movable between a retracted position and an extended position, said shade material extending in a widthwise direction between a first side section and a second side section opposite said first side section;
a frame positioned relative to the architectural opening, said frame defining a guide track configured to receive opposed side sections of said shade material as said shade material is moved between said retracted and extended positions, said guide track including a first side track configured to receive said first side section of said shade material and an opposed second side track configured to receive said second side section of said shade material;
a transverse alignment guide positioned above said first and second side tracks, said transverse alignment guide configured to support an underside of said shade material as said shade material is moved between said retracted and extended positions; and
first and second guide plates positioned above said first and second side tracks respectively, said first and second guide plates extending outwardly from opposed first and second walls of the frame, respectively, in the widthwise direction and being configured to maintain said shade material positioned between said first and second guide plates in said widthwise direction as said shade material moves between said transverse alignment guide and said guide track.

12. The assembly as in claim 11 , further comprising a roller about which said shade material is wound and unwound when said shade material is being moved between said retracted and extended positions, said roller defining a rotational axis that is offset laterally from a forward edge of said transverse alignment guide and said first and second side tracks.

13. The assembly as in claim 11 , wherein:
said transverse alignment guide defines a forward edge; and
said forward edge is vertically aligned with said first and second side tracks.

14. The assembly as in claim 11 , wherein said first and second guide plates are configured to maintain said shade material centered in said widthwise direction between said first and second guide plates as said shade material moves between said transverse alignment guide and said guide track.

15. The assembly as in claim 11 , wherein:
said shade further comprises a plurality of louvers coupled to and extending outwardly from said shade material;
each of said louvers includes opposed side segments that overlie said opposed side sections of said shade material; and
said opposed side segments are received within said first and second side tracks as said shade material is moved between said retracted and extended positions.

16. The assembly as in claim 15 , wherein
each of said louvers includes a first edge coupled to said shade material and a second edge opposite said first edge;
each of said louvers defines a louver depth between said first and second edges; and
said opposed side segments are notched so that each side segment defines a notch depth that is less than said louver depth.

17. The assembly as in claim 16 , wherein said second edge is provided in a cantilevered arrangement relative to said shade material.

18. The assembly as in claim 11 , further comprising a bottom rail coupled to a bottom end of said shade material, said bottom rail extending in the widthwise direction between a first end positioned adjacent to said first side track and a second end positioned adjacent to said second side track, said bottom
