Abstract

An awning assembly with a mount portion, an extendable bar assembly, an upper canopy being retractable to a compact configuration adjacent to the mount portion and extendable to an extended position upon extension of the extendable bar assembly to provide shade from above, a lower canopy coupled with the extendable bar assembly and extendable therefrom to provide shade from a side position. The extendable bar assembly comprises a first roller coupled with the upper canopy, a second roller coupled with the lower canopy and a motion generator coupled with the second roller, the motion generator configured to store energy as the second roller is moved to retract the lower canopy and configured to use the stored energy to move the second roller to extend the lower canopy from the extendable bar assembly.

First claim

What is claimed is:

1 . A method of extending an awning assembly, comprising:
extending a support arm to extend away from a ground surface to move a housing away from the ground surface and to extend an upper canopy away from the ground surface; further extending a terminal length of the upper canopy away from the ground surface after the support arm is fully extended; and engaging a transmission disposed in the housing to move a first roller disposed in the housing to wind up a portion of the upper canopy to tension the upper canopy and to move a second roller disposed in the housing to unfurl a length of a lower canopy from within the housing.

2 . The method of claim 1 , wherein a ratio of the portion of the upper canopy wound up upon engaging the transmission to the length of the lower canopy being unfurled is defined substantially by the transmission coupling the first roller and the second roller.

3 . The method of claim 2 , wherein the ratio is in a range of 1:1 to 1:10.

4 . The method of claim 1 , wherein extending the support arm further comprises unwinding a base roller to extend the upper canopy and further extending the terminal length of the upper canopy comprises further unwinding the base roller.

5 . The method of claim 1 , wherein rotation of the first roller in a first direction causes rotation of the second roller and unfurling of the length of the lower canopy.

6 . The method of claim 1 , wherein the first roller rotates about a first axis and the second roller rotates about a second axis, the first axis spaced a lateral distance from the second axis.

7 . A method of storing an awning assembly, comprising:
retracting an upper canopy to unwind a portion of the upper canopy from a first roller disposed in a moveable housing of the awning assembly; simultaneously with retracting the portion of the upper canopy, winding a vertical length of a lower canopy about a second roller disposed in the moveable housing of the awning assembly; and storing potential energy in a resilient member disposed on or in the moveable housing of the awning assembly while winding the lower canopy.

8 . The method of claim 7 , wherein a ratio of the portion of the upper canopy unwound upon retracting the upper canopy to the vertical length of the lower canopy wound about the second roller is substantially defined by a ratio of rotation of a transmission configured to move the first roller and the second roller.

9 . The method of claim 8 , wherein the ratio of rotation is in a range of 1:1 to 1:10.

10 . The method of claim 7 , wherein the upper canopy is retracted by winding the upper canopy about a base roller.

11 . The method of claim 7 , wherein advancement of a transmission in a first direction retracts the lower canopy and winds the lower canopy about the second roller while unwinding a length of the upper canopy from the first roller.

12 . A method of extending an awning assembly, comprising:
extending a support arm to extend away from a surface to move a housing away from the surface and to extend an upper canopy away from the surface; further extending a terminal length of the upper canopy away from the surface after the support arm is fully extended; and engaging a transmission disposed in the housing to move a first roller disposed in the housing to wind up a portion of the upper canopy to tension the upper canopy and to move a second roller disposed in the housing to unfurl a length of a lower canopy from within the housing, wherein advancement of the transmission in a first direction is configured to tension the upper canopy and deploy the lower canopy.

13 . The method of claim 12 , wherein advancement of the transmission in a second direction is configured to retract the lower canopy and wind the lower canopy about the second roller while unwinding a length of upper canopy from the first roller.

14 . The method of claim 13 , wherein the surface includes a third roller and rotation of the third roller is configured to wind the upper canopy about the third roller, to advance the transmission in the second direction, and to retract the housing towards the surface.

15 . The method of claim 12 , wherein rotation of the first roller in a first direction causes rotation of the second roller and unfurling of the length of the lower canopy.

16 . The method of claim 12 , wherein the first roller rotates about a first axis and the second roller rotates about a second axis, the first axis spaced a lateral distance from the second axis.
