Awning assembly
An awning assembly includes an awning and support arms and rafters that are adapted to support the awning from a backing structure both when the awning is in an extended position and when it is in a retracted position. The support arms and rafters are mounted to the backing structure in a manner that allows for the positions of the support arms and rafters to be readily converted as the awning is extended and retracted. Additionally, the manner in which each rafter is joined to a respective support arm allows for the convenient rearrangement of the rafters and support arms to facilitate supporting of the awning in both the extended and retracted positions. A cooperative awning assembly, on which the awning is wound and unwound, and locking device are provided to lock the awning in place. The awning assembly, in a particular embodiment, is applied to a pop-up trailer.
1. An awning assembly for mounting to a structure including:
a first member including a first proximal end and a first distal end, the first proximal end movably joined to a structure;
a second member including a second proximal end and a second distal end, the second proximal end movably joined to a structure; and
a roller mechanism about which a flexible material may be wound and unwound comprising;
a roller tube having two opposed end portions and a longitudinal axis of rotation extending from one opposed end portion of the roller tube to the other opposed end portion through the center of the roller tube, the roller tube being mounted for rotation in both a clockwise and a counterclockwise direction about the longitudinal axis of rotation and being adapted to be attached to one end of the flexible material, at least one opposed end portion of the roller tube having at least one longitudinal slot extending substantially parallel to the longitudinal axis of rotation of the roller tube; and
a locking device mounted adjacent the at least one opposed end portion of the roller tube having at least one longitudinal slot, the locking device being mounted for selective movement axially of the longitudinal axis of rotation of the roller tube toward and away from the at least one opposed end portion of the roller tube having at least one longitudinal slot and for selective nonrotational movement about the longitudinal axis of rotation of the roller tube, the locking device including locking pins for insertion into respective ones of the at least one longitudinal slot in the roller tube when the locking device is moved into engagement with the at least one opposed end portion of the roller tube having at least one longitudinal slot and for removal from the at least one longitudinal slot when the locking device is moved out of engagement with the at least one opposed end portion of the roller tube having at least one longitudinal slot,
wherein the longitudinal axis of rotation passes through the first distal end and the second distal end and wherein the longitudinal axis of rotation undergoes substantially translational movement as the flexible material is wound and unwound.
2. The awning assembly of claim 1 including a rod extending along the longitudinal axis of rotation of the roller tube, the rod being secured against rotational movement, and a resilient element being connected to the rod and the roller tube so as to resist rotation of the roller tube about the longitudinal axis of rotation in relation to the rod.
3. The awning assembly of claim 2 wherein the rod extends outwardly of at least the at least one opposed end portion of the roller tube that has at least one longitudinal slot and the locking device is mounted on the rod for selective movement axially toward and away from the at least one opposed end portion of the roller tube having at least one longitudinal slot and for selective non-rotational movement with respect to the rod.
4. The awning assembly of claim 3 wherein the at least one opposed end portion of the roller tube having at least one longitudinal slot includes a closure cap through which the rod extends outwardly of the roller tube and by means of which the roller tube is rotatably mounted on the rod, and the at least one longitudinal slot is located in the closure cap.
5. The awning assembly of claim 4 wherein the resilient element comprises a torsion spring through which the rod extends.
6. The awning assembly of claim 5 wherein the at least one closure cap includes two diametrically opposed longitudinal slots and a respective locking device includes two locking pins that are positioned on the locking device so that they may be inserted into the two diametrically opposed slots in the closure cap when the locking device is moved into engagement with the roller tube.
7. The awning assembly of claim 1 wherein each opposed end portion of the roller tube has at least one longitudinal slot extending substantially parallel to the longitudinal axis of rotation of the roller tube and a respective locking device is mounted adjacent each of the opposed end portions of the roller tube.
8. The awning assembly of claim 7 including a rod extending along the longitudinal axis of rotation of the roller tube, the rod being secured against rotational movement, and a resilient element being connected to the rod and the roller tube so as to resist rotation of the roller tube about the longitudinal axis of rotation in relation to the rod.
9. The awning assembly of claim 8 wherein the rod extends outwardly of both opposed end portions of the roller tube and each locking device is mounted on a respective one of the end portions of the rod for selective movement axially toward and away from a respective one of the opposed end portions of the roller tube and for selective nonrotational movement with respect to the rod.
10. The awning assembly of claim 9 wherein each of the opposed end portions of the roller tube includes a closure cap through which the rod extends outwardly of the roller tube and by means of which the roller tube is rotatably mounted on the rod, and the at least one longitudinal slot in each opposed end portion of the roller tube is located in a respective closure cap.
11. The awning assembly of claim 10 wherein each closure cap includes two diametrically opposed longitudinal slots and each locking device includes two locking pins that are positioned on the locking device so that they may be inserted into the two diametrically opposed slots in a respective closure cap when the locking device is moved into engagement with a respective opposed end portion of the roller tube.
12. The awning assembly of claim 11 wherein the resilient element comprises a torsion spring through which the rod extends.
13. The awning assembly of claim 1 , wherein the first and second members include telescoping members supporting the roller mechanism.
14. The awning assembly of claim 13 , wherein the roller mechanism is configured to form a forward border of an awning.
15. The awning assembly of claim 6 , wherein the at least one closure cap includes a first set of two diametrically opposed longitudinal slots and a second set of two diametrically opposed longitudinal slots substantially perpendicular to the first set, the rod includes diametrically opposed lugs, the locking device includes a cruciform slot such that axial movement of the locking device toward and away from the opposed end portions of the roller tube slides the locking device over the opposed lugs.
