Awning with support system having articulated mounting arm

1. In a retractable awning for mounting to a wall, the awning including a roller, a flexible canopy having one end secured to the roller and rollable onto the roller, and a motor operable to rotate the roller to roll the flexible canopy onto or off the roller, the improvement comprising

a. a pair of support arms supporting opposite ends of the roller, each support arm being operable to move from a retracted position proximate the wall where said arm is substantially vertical to an extended position where said arm is substantially horizontal and displaced from said retracted position,

b. a pair of top and bottom mounting arms pivotally connected to and extending from each support arm, each top mounting arm being connected to an upper location on the wall and each bottom mounting arm being connected to a lower location on the wall, at least one of the bottom mounting arms including first and second arm elements, each first arm element pivotally articulated with its corresponding second arm element, and

c. an extensible strut pivotally connected to and extending between each top arm and bottom mounting arm at connection locations spaced from and displaceable from the wall.

2. The retractable awning according to claim 1 , in which said strut comprises a normally-extended pneumatic cylinder.

3. The retractable awning according to claim 1 , in which said first and second arm elements are joined by an adjustment coupler.

4. The retractable awning according to claim 3 , in which said adjustment coupler comprises a bolt.

5. The retractable awning according to claim 3 , in which said adjustment coupler is operable to allow selective displacement of first and second arm elements from an axially-aligned orientation when said awning is extended and realignment said first and second arm elements to an axially-aligned orientation when said awning is returned to the retracted position.

6. The retractable awning according to claim 4 , in which said adjustment coupler further comprises a nut engaged with said bolt.

7. A retractable awning comprising:

a roller;

a flexible canopy having one end secured to the roller and rollable onto the roller;

a motor operable to rotate the roller to roll the flexible canopy onto or off of the roller; and

a support mechanism comprising:

a. a stile;

b. a pair of support arms supporting opposite ends of the roller, each support arm being operable to move from a retracted position where the support arm is substantially parallel to and proximate the stile to an extended position where the support arm is substantially perpendicular to and displaced from the stile;

c. a pair of top and bottom mounting arms pivotally connected to and extending from each support arm, each top mounting arm being connected to a top mounting arm location on the stile, a bottom mounting arm being connected to a bottom mounting arm location on the stile, at least one of the bottom mounting arms comprising first and second arm elements, each first arm element in pivotally articulated engagement with its corresponding second arm element; and

d. an extensible strut pivotally connected to and extending between each top arm and bottom mounting arm at connection locations spaced from and displaceable from the stile.

8. The retractable awning according to claim 7 , further comprising an adjustment coupler joining said first and second arm elements.

9. The retractable awning according to claim 8 , in which said adjustment coupler comprises a bolt.

10. The retractable awning according to claim 9 , in which said adjustment coupler further comprises a nut engaged with said bolt.

11. The retractable awning according to claim 7 , in which said strut comprises a normally-extended pneumatic cylinder.

12. The retractable awning according to claim 7 , in which said top and bottom mounting arms are pivotally connected to each support arm at corresponding connection points, at least one of said connection points comprising a bearing.

13. The retractable awning according to claim 7 , in which said adjustment coupler is operable to allow selective displacement of first and second arm elements from an axially-aligned orientation when said awning is extended and realignment said first and second arm elements to an axially-aligned orientation when said awning is returned to the retracted position.

14. A retractable awning comprising:

a roller;

a flexible canopy having one end secured to the roller and rollable onto the roller;

a motor operable to rotate the roller to roll the flexible canopy onto or off of the roller; and

a support mechanism configured for attachment to a wall, comprising:

a. a pair of support arms supporting opposite ends of the roller, each support arm being operable to move from a retracted position where the support arm is substantially parallel to and proximate the wall to an extended position where the support arm is substantially perpendicular to and displaced from the wall;

b. a pair of top and bottom mounting arms pivotally connected to and extending from each support arm, each top mounting arm being configured for connection to a top mounting arm location on the wall, a bottom mounting arm being configured for connection to a bottom mounting arm location on the wall, at least one of the bottom mounting arms comprising first and second arm elements, each first arm element in pivotally articulated engagement with its corresponding second arm element; and

c. an extensible strut pivotally connected to and extending between each top arm and bottom mounting arm at connection locations spaced from and displaceable from the wall.

15. The retractable awning according to claim 14 , further comprising an adjustment coupler joining said first and second arm elements.

16. The retractable awning according to claim 15 , in which said adjustment coupler comprises a bolt.

17. The retractable awning according to claim 16 , in which said adjustment coupler further comprises a nut engaged with said bolt.

18. The retractable awning according to claim 14 , in which said strut comprises a normally-extended pneumatic cylinder.

19. The retractable awning according to claim 7 , in which said adjustment coupler is operable to allow selective displacement of first and second arm elements from an axially-aligned orientation when said awning is extended and realignment said first and second arm elements to an axially-aligned orientation when said awning is returned to the retracted position.
