发明名称 Portable hunter's ladder
摘要 A portable, hunter's ladder, useful in climbing trees comprising a pair of tubular rails radiused at each end forming a generally "C-shaped" configuration with their ends turned at oblique angles towards each other. A plurality of rungs, spaced along the rail's length, hold the rails in a substantially parallel relationship and are spaced at regular intervals except for the uppermost rung which is placed adjacent the upper, rail radius leaving an unequal spacing between the upper two rungs. Thus providing the climber with a better footing advantage when traversing around a tree to avoid limbs or when transferring to another ladder or tree stand.
