A covering for architectural openings including a roller, a shade wrapped around the roller, the shade extendable from the roller when the roller rotates in a first direction, and retractable onto the roller when the roller rotates in a second direction. The covering also includes a retraction mechanism operably associated with the roller for biasing the roller in a direction to retract the shade and a positioning device operably engaging the roller for selectively holding the shade at a selected extension location and selectively releasing the shade for additional extension or retraction. The positioning device is actuated to hold the shade at the selected extension position by movement of the shade in either the extension or retraction direction.

1. A covering for architectural openings, the covering comprising: a roller;a shade wrapped around the roller, the shade extendable from the roller when the roller rotates in a first direction, and retractable onto the roller when the roller rotates in a second direction;a retraction mechanism operably associated with the roller for biasing the roller in a direction to retract the shade;a positioning device operably engaging the roller for selectively holding the shade at a selected extension location and selectively releasing the shade for additional extension or retraction; wherein:the positioning device comprises: a spool selectively rotatable with the roller; anda shuttle at least partially received around the spool;the shuttle translates along a length of the spool as the roller rotates; andthe positioning device is actuated to hold the shade at the selected extension position by movement of the shade in either the extension or retraction direction. 2. The covering of claim 1, wherein: when the shuttle is in a first position on the spool, the roller can rotate; andwhen the shuttle is in a second position on the spool, the roller is prevented from rotating. 3. The covering of claim 2, wherein: an outer surface of the spool defines a pin engagement surface defining a plurality of channels;the shuttle comprises at least one pin, wherein the at least one pin is configured to travel within the plurality of channels; andthe location of the at least one pin on the pin engagement surface determines whether the shuttle can rotate or whether the shuttle is prevented from rotating. 4. The covering of claim 2, wherein the positioning device further comprises: an engagement disk operably connected to the roller and the spool and operably connecting the spool to the roller; anda clutch operably connected to the engagement disk and the spool;wherein when the shuttle is in the second position the clutch prevents the engagement disk from rotating, preventing the roller from rotating. 5. The covering of claim 1, wherein the positioning device further comprises a retainer received around the spool and the shuttle. 6. The covering of claim 5, wherein: the shuttle includes a plurality of translation features defined on an outer surface;the retainer includes a plurality of guide grooves defined on interior surface; andthe translation features of the shuttle are received into the guide grooves of the retainer, and when the translation features are received into the guide grooves the shuttle translates along the length of the spool as the spool rotates. 7. The covering of claim 1, wherein: the positioning device further comprises at least one locking element;the spool includes an outer surface defining a first seat and a second seat;when the locking element is in the first seat, the positioning device locks the roller to hold the shade at the selected extension location; andwhen the locking element is in the second seat, the positioning device unlocks the roller. 8. The covering of claim 7, wherein the locking element is defined on the shuttle. 9. The covering of claim 7, wherein the positioning device further comprises an engagement disk operably connecting the spool and the roller, wherein the engagement disk is rotatably connected to the roller. 10. The covering of claim 9, wherein the positioning device further comprises a clutch spring having a spool tang and a disk tang, wherein the spool tang is operably connected to the spool and the disk tang is operably connected to the engagement disk, wherein the clutch spring substantially prevents the spool from rotating relative to the engagement disk. 11. The covering of claim 1, wherein: the shuttle engages the spool; andthe location of the engagement determines whether the shuttle can rotate or whether the shuttle is prevented from rotating. 12. The covering of claim 1, wherein: the positioning device further comprises at least one locking element;the spool defines a first seat and a second seat;when the locking element is in the first seat, the positioning device locks the roller; andwhen the locking element is in the second seat, the positioning device unlocks the roller. 13. A method for operating a covering for an architectural opening, the method comprising: moving a shade in a first direction to a first position;moving the shade in a second direction from the first position to hold the shade at a selected position;rotating a spool during movement of the shade; andtranslating a non-rotatable shuttle received at least partially around the spool along a length of the spool during rotation of the spool, the shuttle selectively locking with respect to the spool as the spool rotates with respect to the shuttle to restrict movement of the shade at the selected position, or unlocking with respect to the spool to permit extension and retraction of the shade from the selected position. 14. The method of claim 13, further comprising moving the shade in the first direction, after the translating of the non-rotatable shuttle during rotation of the spool, to unlock the shuttle with respect to the spool. 15. The method of claim 14, wherein a retraction mechanism of the shade moves the shade in the second direction from the first position after the moving of the shade in the first direction. 16. The method of claim 14, wherein the second direction wraps the shade onto the roller. 17. The method of claim 13, further comprising rotating an engagement disk during movement of the shade to cause rotation of the spool. 18. The method of claim 13, further comprising translating the shuttle relative to a non-rotatable retainer during rotation of the spool, the retainer restricting the shuttle from rotating with the spool. 19. A shade comprising: a roller;at least one sheet operably connected to the roller;a retraction motor operably connected to the roller, wherein the retraction motor exerts a biasing force to bias the roller in a first direction; anda locking assembly operably connected to the roller;wherein: the locking assembly selectively overcomes the biasing force of the retraction motor; andthe locking assembly comprises: a spool rotatable with the roller; anda shuttle received around a portion of the spool and traversable along a length of the spool. 20. The shade of claim 19, further comprising: a support rod operably connected to the head rail and the locking assembly; andthe locking assembly further comprises a retainer received around the spool and the shuttle and operably connected to the roller;wherein the retainer prevents the shuttle from rotating with the spool. 21. The shade of claim 20, wherein: the spool defines a pin engagement surface defining a first engagement feature;the shuttle includes at least one pin that selectively engages the pin engagement surface; andwhen the at least one pin engages the first engagement feature, the at least one pin substantially prevents the spool from rotating. 22. The shade of claim 21, wherein: the locking assembly further comprises a clutch spring operably connected between the spool and the roller; andwhen the pin engages the first engagement feature, the clutch is biased to a closed position. 23. The shade of claim 19, wherein: the shuttle engages the spool; andthe location of the engagement determines whether the shuttle can rotate or whether the shuttle is prevented from rotating.
