US 2003/0146048 A1 · Extension ladder and tree stand

Abstract

An extension ladder and tree stand for supporting a seated or standing person on an elevated platform against a tree trunk for hunting, photography, and the like. The ladder and platform collapse into a compact size and shape for carrying by a person. The ladder is in telescoping sections. Alternate steps of the ladder slide to the middle of each telescoping section. This provides twice as many steps as sections, reducing the number of telescoping sections by half. This minimizes weight, size, complexity, and expense. When deployed, all parts remain safely assembled in all positions. Captive spring loaded pins fix the telescoping sections in extended or retracted positions, and fix the sliding steps in a middle position of each section. A folding seat on the platform has a cushion that reconfigures into a back cushion for carrying the collapsed assembly on the back of a person.

Dependent claims

A portable extension ladder comprising:

a first elongated tubular section having an interior, an exterior, a top end, and a bottom end;
a second elongated tubular section having a top end, a bottom end, an interior, and an exterior, the exterior having front and back sides;
the first tubular section slidably nested in the interior of the second tubular section and extending from the bottom end of the second tubular section;
a section slide stopping mechanism that releasably fixes the first tubular section in an extended position from the second tubular section;
a bottom step mounted on the bottom end of the first tubular section;
a middle step slidably mounted on the exterior of the first tubular section between the bottom step and the top end of the first tubular section;
and
a middle step slide stopping mechanism that releasably fixes the middle step at an intermediate position on the first tubular section between the bottom step and the top end of the first tubular section.
