Lateral arm awning system and method of operation
A lateral arm assembly and method of operation includes first and second articulating arms comprising first and second ends, the first ends of the articulating arms are mounted upon assembly to a support surface at separate lateral locations. The first ends each comprise separate pivoting mounting structures for forming a first pivotal connection with the first and second articulating arms. The lateral arm assembly also comprises a roller tube having spaced lateral ends supporting respective end brackets that provide a second pivotal connection to the second ends of the articulating arms. The roller tube supports a canopy coupled to a roller shaft, wherein one of the end brackets further supports a device that drives the roller shaft for furling and unfurling the canopy.
1. A lateral arm awning assembly comprising:
first and second articulating arms having first and second ends, said first ends of said articulating arms being mounted upon assembly to a support surface at separate lateral locations, the first ends each comprising separate pivoting mounting structures for forming a pivotally fixedly connection with said first and second articulating arms; and
a roller tube having spaced lateral ends supporting respective end brackets that provide a pivotally fixedly connection to said second ends of said first and second articulating arms;
said roller tube supporting a canopy coupled to a roller shaft, wherein one of the end brackets further supports a drive that drives said roller shaft for furling and unfurling said canopy;
said canopy when in an unfurled position forming a plane such that said first and second articulating arms are disposed to remain substantially parallel with said plane during the operation of the awning assembly as the canopy extends from a furled to an unfurled position;
said roller tube moving relative to said support surface as the canopy extends from the furled position to the unfurled position to move said roller tube away from said support surface, said lateral arm awning assembly being supported solely by said first and second articulating arms when the canopy is in the unfurled position.
2. The lateral arm awning assembly of claim 1 wherein said drive comprises a drive motor.
3. The lateral arm assembly of claim 1 further comprising first and second springs each coupled to respective first and second lateral arms, said first and second springs providing tension to said canopy during movement between the furled and unfurled positions of the awning assembly.
4. The lateral arm assembly of claim 3 wherein said first and second lateral arms further comprise an extruded tube having a central cavity formed by a plurality of sidewalls, wherein one of said plurality of sidewalls includes a channel extending along the length of said first and second lateral arms for supporting and concealing said first and second springs when said canopy is in the furled position.
5. The lateral arm assembly of claim 3 wherein said first and second springs are disposed to remain substantially parallel with said plane during the operation of the awning assembly as the canopy extends from the furled to the unfurled position.
6. A lateral arm awning assembly for attachment to a support structure, said assembly comprising:
first and second mounting plates mounted upon assembly directly to the structure at separate lateral locations;
first and second articulating arms each including a proximal arm pivotably connected to a distal arm, said proximal arm of each of said first and second articulating arms comprising separate pivoting mounting structures for forming a pivotally fixedly connection with said first and second mounting plates; and
a roller tube having spaced lateral ends supporting respective end brackets that provide a pivotally fixedly connection to said second ends of said first and second articulating arms;
said roller tube supporting a canopy coupled to a roller shaft, wherein one of the end brackets further supports a drive that drives said roller shaft for furling and unfurling said canopy;
said canopy when in an unfurled position forming a plane such that said first and second articulating arms are disposed to remain substantially parallel with said plane during the operation of the awning assembly as the canopy extends from a furled to an unfurled position, said lateral arm awning assembly being supported solely by said first and second articulating arms when said canopy is in the unfurled position.
7. The lateral arm assembly of claim 6 further comprising first and second springs each coupled to respective first and second lateral arms, said first and second springs providing tension to said canopy during movement between the furled and unfurled positions of the awning assembly.
8. The lateral arm assembly of claim 7 wherein said first and second lateral arms further comprise an extruded tube having a central cavity formed by a plurality of sidewalls, wherein one of said plurality of sidewalls includes a channel extending along the length of said first and second lateral arms for supporting and concealing said first and second second springs when said canopy is in the furled position.
9. The lateral arm assembly of claim 7 wherein said first and second springs are disposed to remain substantially parallel with said plane during the operation of the awning assembly as the canopy extends from the furled to the unfurled position.
