A retractable stand comprises a base, two ribbons, and a locking mechanism. Each ribbon has a coiled portion and an uncoiled portion. The uncoiled portions have a curved cross-sectional shape positioned in opposing relation to each other. The locking mechanism is movable between an unlocked position and a locked position where the at least one ribbon is substantially inhibited from moving relative to the base in at least one direction. The locking mechanism can comprise an auto-locking member biased toward the locked position. The locking mechanism can further comprise a trigger mounted on the base and accessible by the user to move the auto-locking member to the unlocked position. Preferably, the retractable stand further includes a manual locking mechanism that can be manually selectively moved between unlocked and locked positions to selectively lock and unlock a position of at least one of the ribbons relative to the base.

1. A retractable stand comprising: a base adapted to support a device; two ribbons, each having a coiled portion and an uncoiled portion, wherein the uncoiled portions of the ribbons have a curved cross-sectional shape and are positioned in opposing relation to each other;a brace secured to free end
1. A retractable stand comprising: a base adapted to support a device; two ribbons, each having a coiled portion and an uncoiled portion, wherein the uncoiled portions of the ribbons have a curved cross-sectional shape and are positioned in opposing relation to each other;a brace secured to free ends of the uncoiled portions of the ribbons such that the uncoiled portions of the ribbons support the base on the brace without additional structural support below the base; anda locking mechanism mounted on the base and movable between an unlocked position where at least one ribbon is substantially permitted to move relative to the base and a locked position where the at least one ribbon is substantially inhibited from moving relative to the base in at least one direction. 2. A retractable stand as claimed in claim 1, wherein the base comprises a housing that substantially entirely encloses the coiled portions of the two ribbons. 3. A retractable stand as claimed in claim 1, wherein the curved cross-sectional shape of each uncoiled portion defines a convex surface and a concave surface, and wherein the convex surfaces of the uncoiled portions of the ribbons are in facing relation to each other. 4. A retractable stand as claimed in claim 1, wherein the locking mechanism comprises a cam lock actuator. 5. A retractable stand as claimed in claim 1, wherein the locked position substantially inhibits movement of the at least ribbon into the base but does not substantially inhibit movement of the at least one ribbon out of the base. 6. A retractable stand as claimed in claim 1, wherein the locking mechanism comprises a biased locking mechanism having an auto-locking member biased toward the locked position. 7. A retractable stand as claimed in claim 6, wherein the locking mechanism further comprises a trigger mounted on the base and accessible by the user to move the auto-locking member to the unlocked position. 8. A retractable stand as claimed in claim 7, wherein the retractable stand further includes a manual locking mechanism that can be manually selectively moved between unlocked and locked positions to selectively lock and unlock a position of at least one of the ribbons relative to the base. 9. A retractable stand as claimed in claim 8, wherein the manual locking mechanism includes at least two manual locking members. 10. A retractable stand as claimed in claim 9, wherein both of the manual locking members are biased toward an unlocked position. 11. A method of using a retractable stand having a base, two ribbons each having a coiled portion positioned in the base and an uncoiled portion extending from the base wherein the uncoiled portions of the ribbons have a curved cross-sectional shape and are positioned in opposing relation to each other, and a locking mechanism mounted on the base, the method comprising: moving a free end of the uncoiled portions of the ribbons away from the base to thereby uncoil a portion of the ribbons, wherein the free end includes a foot brace, and wherein moving the free end includes placing a user's foot on the foot brace;supporting the free end on a supporting surface below the base;substantially inhibiting movement of the free end toward the base using the locking mechanism;holding the base above the supporting surface; andpositioning a device on the base. 12. A method as claimed in claim 11, wherein the locking mechanism includes a cam lock actuator, and wherein substantially inhibiting includes moving the cam lock actuator from an unlocked position to a locked position. 13. A method as claimed in claim 11, wherein substantially inhibiting includes substantially permitting movement of the free end away from the base. 14. A method as claimed in claim 11, further comprising retracting the free end toward the base until the uncoiled portions of the ribbons are completely housed within the base. 15. A method as claimed in claim 14, wherein the locking mechanism includes an auto-locking member biased toward a locked position and a trigger mounted on the base and accessible by the user to move the locking member from the locked position to an unlocked position, and wherein retracting comprises moving the trigger. 16. A method as claimed in claim 15, wherein the retractable stand further includes a manual locking mechanism that is manually movable between unlocked and locked positions to selectively lock and unlock a position of at least one of the ribbons relative to the base, and wherein the method further includes, after the moving step and before the retracting step, the step of manually moving the manual locking mechanism to the locked position. 17. A method as claimed in claim 11, wherein the devices comprises a rifle, a pistol, a still camera, a video camera, or a cross bow. 18. A retractable stand comprising: a base adapted to support a device;first and second ribbons, each having a coiled portion and an uncoiled portion, wherein the uncoiled portions of the ribbons have a curved cross-sectional shape and are positioned in opposing relation to each other; anda locking mechanism mounted on the base and movable between an unlocked position where the first ribbon is substantially permitted to move relative to the base and a locked position engaging the first ribbon to substantially inhibited the first ribbon from moving relative to the base in at least one direction. 19. A retractable stand as claimed in claim 18, wherein the curved cross-sectional shape of each ribbon defines a concave surface, and wherein the locking mechanism includes a first locking member having a convex surface engageable with the concave surface of the first ribbon when the locking mechanism is in the locked position. 20. A retractable stand as claims in claim 19, wherein the locking mechanism further includes a second locking member having a convex surface engageable with the concave surface of the second ribbon when the locking mechanism is in the locked position.
