Trough shade system and method
View Patent ↗A trough shade system and method of use provide improved support for a roller tube and shade material. The roller tube and wound shade material are located within a support cradle to minimize unwanted deflection by the roller tube and associated wrinkling and deformation of the shade material. Various mechanisms allow the roller tube a limited range of movement within the support cradle. The system is suitable for shading larger areas than other shading systems which rely on roller tubes with fixed supports at the ends.
1. A shade system, comprising:
a roller tube having a roller axis;
a shade material wound on the roller tube;
a support cradle configured to support the roller tube; and
a floating plate configured with:
a first channel configured to allow the roller axis of the roller tube to move a limited range along only a first axis of movement with respect to the support cradle; and
a second channel configured to allow the roller axis of the roller tube to move a limited range along only a second axis of movement with respect to the support cradle.
2. The system of claim 1 , further comprising a motor plate affixed to the roller tube and received into the first channel of the floating plate.
3. The system of claim 2 , further comprising an end cap having rollers received into a second channel of the floating plate.
4. The system of claim 1 , wherein the roller tube has a first end and a second end, and wherein the floating plate comprises a first floating plate interfacing with the first end and a second floating plate interfacing with the second end.
5. The system of claim 1 , further comprising a fascia covering the roller tube.
6. The system of claim 1 , wherein the shade material is deployed in a constant plane with respect to a shaded surface.
7. The system of claim 1 , wherein the shade material is deployed at a variable distance from a shaded surface.
8. The system of claim 1 , wherein the support cradle comprises a bull nose at the feed side of the support cradle.
9. The system of claim 1 , wherein the support cradle comprises a tube dam at the feed side of the support cradle.
10. The system of claim 1 , wherein the first axis of movement is horizontal, and wherein the second axis of movement is vertical.
11. The system of claim 1 , wherein movement of the roller axis of the roller tube along the first axis of movement is independent of movement of the roller axis of the roller tube along the second axis of movement.
12. A method for enabling movement of a roller tube in a shade system, the method comprising:
at least one of rolling or unrolling a shade material around the roller tube, wherein a support cradle supports the roller tube; and,
moving, with respect to the support cradle, the roller axis of the roller tube, wherein the moving is guided by a floating plate configured with:
a first channel configured to allow the roller axis of the roller tube to move a limited range along only a first axis of movement with respect to the support cradle; and
a second channel configured to allow the roller axis of the roller tube to move a limited range along only a second axis of movement with respect to the support cradle.
13. The method of claim 12 , wherein the moving is further guided by:
a motor plate affixed to the roller tube and received into the first channel of the floating plate; and
an end cap having rollers received into the second channel of the floating plate.
14. The method of claim 12 , wherein the at least one of rolling or unrolling a shade material is performed with the shade material in a constant plane with respect to a shaded surface.
15. The method of claim 12 , wherein the at least one of rolling or unrolling a shade material is performed with the shade material at a variable distance from a shaded surface.
16. A shade system, comprising:
a roller tube having a roller axis;
a shade material wound on the roller tube;
a support cradle configured to support the roller tube;
a floating plate configured with:
a first channel configured to allow the roller axis of the roller tube to move a limited range along a first axis of movement with respect to the support cradle; and
a second channel configured to allow the roller axis of the roller tube to move a limited range along a second axis of movement with respect to the support cradle;
a motor plate affixed to the roller tube and received into the first channel of the floating plate; and
an end cap having rollers received into the second channel of the floating plate.
