  • Patent number: 6718995
    Abstract: A collapsible awning (50) for a collapsible shelter (10) including canopy (15) supported by collapsible structure (20) including truss network (40) and legs (21). Collapsible awning (50) includes awning (90) supported by collapsible awning support (51). Awning support (51) includes a pair of side supports (52), each attached to a leg (21) of structure (20). Each side support (52) includes an arm (61) having a proximal end (62) pivotly attached to upper end (23) of leg (21) and a distal end (64) a strut (71) having outer end (74) pivotly attached to arm (61) and inner end (72) pivotly attached to slider (76) that slides up leg (21) to move side support (52) from a collapsed position to an erect position, wherein arm (61) is pivoted outward from leg (21). Awning (90) is attached to and snaps between arms (71).

  • Patent number: 6708707
    Abstract: A collapsible support (10) for a canopy (15) comprises a peripheral structure (20) and a central structure (60). Peripheral structure (20) includes four telescopingly collapsible legs (21), each having a sliding member (35) slidingly connected thereto and four pairs (40P) of X-configured truss structures (41) connecting legs (21). Central structure (60) connects between opposite side X-configured truss structure pairs (40P) and is supported thereby. Central structure (60) generally includes a center post assembly (61) supported by two pairs of orthogonal center trusses (80). Canopy (15) is attached to peripheral structure (20) so as to tension canopy (15) over center post assembly (61) in an erect configuration.
