Patent ID: 7240687

Claim:
An erectable, collapsible shelter having a collapsed configuration and an extended configuration, comprising: a canopy; a plurality of legs having at least three legs supporting said canopy, said legs having an upper end and a lower end; a perimeter truss linkage assembly having a plurality of perimeter truss pairs of link members connected to said legs; and a canopy peak support assembly movable between a raised position and a lowered position, said canopy peak support assembly supporting said canopy above the top of the legs in said raised position, said canopy peak support assembly including a plurality of telescoping pole members having first and second ends, said first ends of said telescoping pole members being pivotally connected together, and said second ends of said telescoping pole members being pivotally connected to the legs, each of said telescoping pole members including hollow first and second telescoping sections slidably connected together, said first telescoping section slidably disposed within said second telescoping section and having a distal end for supporting said canopy and a proximal end, said second telescoping section having a spring loaded detent pin and an aperture for receiving said spring loaded detent pin, said first telescoping section having a corresponding medially located aperture located medially of said proximal end for receiving said spring loaded detent pin, whereby when said apertures of said first and second telescoping sections are aligned, said first and second telescoping sections are locked together by said detent pin, said first telescoping section including a second aperture for receiving said spring loaded detent pin proximal to said medially located aperture, said surface of said first telescoping section defining said second aperture and a ramped channel for receiving said detent pin extending and becoming shallower distally from said second aperture, such that when said detent pin is received in said second aperture, said detent pin locks said first and second telescoping sections from being disengaged, and said detent pin can slide distally from said second aperture along said channel.
