The quickly erectable dome shelter includes an extendible perimeter truss assembly with link members connected between adjacent legs, a central truss assembly of link members, and a roof framework, including pairs of curved upper and lower peak truss members, that is movable between a lowered, collapsed configuration and a raised, upwardly arching position. The shelter also includes telescoping peak pole members coupled to the central truss assembly of link members and the roof framework, and may also include telescoping peak truss brace members connected between a peak truss member and a link member of the perimeter assembly of link members.
1. A quickly erectable dome shelter having opposing front and rear sides and opposing lateral sides, comprising:
an extendible perimeter truss assembly having opposing front and rear sides, said extendible perimeter truss assembly including a plurality of legs and a plurality of perimeter truss pairs of link members connected between adjacent legs, each of said perimeter truss pairs of link members having inner and outer ends, and each of said legs having an upper end and a lower end;
a roof framework pivotally mounted to the extendible perimeter truss assembly so as to extend across the shelter in an extended raised, upwardly arching configuration, and said roof framework being movable between a lowered, collapsed configuration and the raised, upwardly arching position, wherein said roof framework comprises a plurality of articulated peak truss assemblies each including a plurality of first and second pairs of curved upper peak truss members and curved lower peak truss members, said plurality of first and second pairs of curved upper peak truss members including front side and rear side pairs of first and second pairs of curved upper peak truss members;
a central truss assembly of link members connected between the front and rear sides of the extendible perimeter truss assembly, and connected between opposing lateral sides of the extendible perimeter truss assembly to stabilize and support the quickly erectable dome shelter, wherein said plurality of articulated peak truss assemblies includes a center pair of first and second pairs of curved upper peak truss members and curved lower peak truss members, and the bottom end portions of the center lower peak truss members are pivotally connected by a center peak mount bracket to the extendible perimeter truss assembly of link members and to the central truss assembly of link members; and
front side and rear side vertically oriented side telescoping peak pole members, said front side and rear side vertically oriented side telescoping peak pole members being pivotally connected to the front side and rear side pairs of first and second pairs of curved upper peak truss members.
2. The quickly erectable dome shelter of claim 1 , wherein said central truss assembly of link members includes a plurality of central truss pairs of link members each having inner and outer ends, with each of the central truss pairs of link members being pivotally connected to the inner ends of the perimeter truss pairs of link members.
3. The quickly erectable dome shelter of claim 2 , wherein each of said central truss pairs of link members is pivotally connected to the inner ends of the perimeter truss pairs of link members by right angle bracket members, to which the inner ends of the perimeter truss pairs of link members and the outer ends of the central truss pairs of link members are pivotally connected.
4. The quickly erectable dome shelter of claim 2 , wherein each of said central truss pairs of link members comprises a first link and a second link and each of said perimeter truss pair of link members include a first link and a second link, said first link of said central truss pairs of link members having an outer end connected to the inner end of the second link of the perimeter truss pair of link members, an inner end, and a central truss pivot point located approximately at a longitudinal center point of the central truss pair first link, said second link of said central truss pairs of link members having an outer end connected to the inner end of the first link of the perimeter truss pair of link members, an inner end, and a central truss pivot point located approximately at the longitudinal center point of the central truss pair second link.
