Abstract:
1. In a telescoping pole assembly for an erectable, collapsible shelter having a plurality of legs, the telescoping pole assembly comprising a plurality of telescoping pole members being mounted to the legs, said telescoping pole members each including first and second hollow telescoping sections slidably connected together, and a spring loaded detent pin mounted to said second telescoping section, the improvement in the telescoping pole assembly comprising: at least one of said telescoping sections including means for blocking the spring loaded detent pin when the first telescoping section is above the second telescoping section to allow the telescoping pole assembly to be raised to a fully extended position, and the means for blocking the spring loaded detent pin not blocking the spring loaded detent pin when the first telescoping section is below the second telescoping section to allow the telescoping pole assembly to be locked in an unextended position; and an aperture defined in the second telescoping section for receiving the spring loaded detent pin, and a medially located aperture defined in the first telescoping section medially of a proximal end of the first telescoping section, and wherein the first telescoping section comprises a second aperture for receiving the spring loaded detent pin proximal to the medially located aperture, the surface of the first telescoping section defining a ramped channel for receiving the detent pin extending and becoming shallower distally from the second aperture, such that when the detent pin is received in the second aperture, the detent pin locks the first and second telescoping sections from being disengaged, and the detent pin can slide distally from the second aperture along the channel.
