Erectable shelter with collapsible central roof support

1. In an erectable, collapsible shelter having a collapsed configuration and an extended configuration, the erectable, collapsible shelter including a canopy having at least three sides and three corners; a leg assembly 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 leg assembly; and a canopy peak support assembly connected to the leg assembly, said canopy peak support assembly including a plurality of telescoping pole members, and said canopy peak support assembly being movable between a raised position and a lowered position, the improvement in the erectable, collapsible shelter comprising:

said telescoping pole members having distal and proximal ends, said telescoping pole members including an inner telescoping section and an outer telescoping section slidably connected together, said outer telescoping section having a spring loaded detent pin, said inner telescoping section having proximal and distal sections, at least one said inner telescoping section having an outer surface defining a ramped channel and a proximal aperture adjacent to the ramped channel, said ramped channel and said proximal aperture being configured to receive the spring loaded detent pin, said ramped channel tapering and becoming shallower distally from the proximal aperture, such that when the spring loaded detent pin is received in the proximal aperture, the spring loaded detent pin locks the inner and outer telescoping sections from being disengaged, and the spring loaded detent pin can slide from the proximal aperture along the channel.

2. The erectable, collapsible shelter of claim 1 , wherein said inner telescoping section includes a medial aperture located distally of said proximal aperture and configured to receive said spring loaded detent pin, said inner telescoping section having a weighted internal stop member slidably disposed within said inner telescoping section, and said weighted internal stop member being moveable between a first position blocking said spring loaded detent pin from entering said medial aperture and a second position not blocking said spring loaded detent pin from entering said medial aperture.

3. The erectable, collapsible shelter of claim 2 , wherein said weighted internal stop member is retained between first and second stop members disposed within said inner telescoping section.
