Claims

[Scope of utility model registration request]

A required number of columns each having a C-shaped cross section provided with a foot section are slidably inserted one after another, each of the columns is extended, and the engaging members provided at the ends of each column are engaged with each other. In the telescoping ladder, each of the engaging members at the end of each of the pillars is connected to any other engaging member other than the engaging members that engage with each other within the inner cross-sectional space of each pillar. An extendable ladder characterized in that the ladders are arranged alternately so as not to interfere with each other.
