Awning system
A retractable awning system includes an awning and a support structure therefor. The support structure includes a base and first, second, and third support arms. The awning is attached to a roller connected to the third support arm and to another structure. A telescopic actuator coupled to the first and second support arms is configured to bias the first, second, and third support arms to a deployed state. The awning may be wound onto the roller. Tension in the awning resulting from the rolling process causes the support structure to transition to a collapsed position.
1. An awning support system comprising:
a base configured for attachment to a structure, said base comprising a first pivot point and a second pivot point spaced apart from said first pivot point;
a first support arm rotatably connected to said base at said first pivot point;
a second support arm rotatably connected to said base at said second pivot point;
a third support arm defining a third pivot point and a fourth pivot point spaced apart from said third pivot point, said third support arm rotatably connected to said second support arm at said third pivot point and said third support arm rotatably connected to said first support arm at said fourth pivot point;
a telescopic actuator having a first end rotatably connected to said second support arm at a fifth pivot point and a second end rotatably connected to said first support arm at a sixth pivot point; and
a biasing member disposed between said telescopic actuator and said second support arm or between said second support arm and said base, said biasing member configured to bias said second support arm apart from said telescopic actuator or said base, respectively, when said first, second, and third support arms are in said second position;
wherein said first, second, and third support arms are movable between a first position in which said first, second, and third support arms extend away from said base and a second position in which said first, second, and third support arms are positioned proximate said base; and
wherein said first support arm is elastically bent when said first, second, and third support arms are in said second position.
2. The system of claim 1 wherein said biasing member is disposed between said telescopic actuator and said second support arm.
3. The system of claim 1 wherein said biasing member is disposed between said second support arm and said base.
4. The system of claim 1 wherein said second support arm comprises a first section and a second section rotatably connected to said first section at a seventh pivot point.
5. The system of claim 4 wherein said seventh pivot point selectively maintains said first section in a non-collinear orientation with respect to said second section.
6. The system of claim 4 wherein said seventh pivot point comprises a Belleville washer.
7. The system of claim 1 wherein said first, second, and third support arms nest in said base when said first, second, and third support arms are in said second position.
8. The system of claim 1 wherein said fifth pivot point is between said second pivot point and said third pivot point.
9. The system of claim 1 further comprising a head unit connected to said third support arm.
10. An awning system comprising a pair of awning support systems as recited in claim 8 and an awning roller connected between said head unit of a first of said awning support systems and said head unit of a second of said awning support systems.
11. An awning support system comprising:
a base configured for attachment to a structure, said base comprising a first pivot point and a second pivot point spaced apart from said first pivot point;
a first support arm rotatably connected to said base at said first pivot point;
a second support arm rotatably connected to said base at said second pivot point;
a third support arm defining a third pivot point and a fourth pivot point spaced apart from said third pivot point, said third support arm rotatably connected to said second support arm at said third pivot point and said third support arm rotatably connected to said first support arm at said fourth pivot point; and
a telescopic actuator having a first end rotatably connected to said second support arm at a fifth pivot point and a second end rotatably connected to said first support arm at a sixth pivot point; and
wherein said first, second, and third support arms are movable between a first position in which said first, second, and third support arms extend away from said base and a second position in which said first, second, and third support arms are positioned proximate said base; and
wherein said first support arm is elastically bent when said first support arm when said first, second, and third support arms are in said second position.
12. The system of claim 11 wherein said second support arm comprises a first section and a second section rotatably connected to said first section at a seventh pivot point.
13. The system of claim 12 wherein said seventh pivot point selectively maintains said first section in a non-collinear orientation with respect to said second section.
14. The system of claim 11 further comprising a head unit connected to said third support arm.
15. An awning system comprising a pair of awning support systems as recited in claim 14 and an awning roller connected between said head unit of a first of said awning support systems and said head unit of a second of said awning support systems.
16. The system of claim 11 wherein said second support arm comprises a first section and a second section rotatably connected to said first section at a seventh pivot point.
17. The system of claim 12 wherein said seventh pivot point selectively maintains said first section in a non-collinear orientation with respect to said second section.
