A VERTICALLY ORIENTATED LADDER APPARATUS FOR ALLOWING A CLIMBER TO ADOPT AN IMPROVED CLIMBING STANCE IN USE
A vertical ladder has two side stiles and at least one front vertical rail. Two sets of half treads are supported by each stile and horizontal rung members connected between at least one rail and a respective half tread or stile. Each horizontal rung member only has a front straight bar portion that terminates orthogonally at the at least one rail (i.e. at a T-junction), thereby allowing a vertical grab rail portion for gripping (including for counterbalance) and an orthogonal side straight bar portion. The rung members and half treads are alternately vertically staggered. As such, a user may ascend the ladder by stepping sideways onto the inward facing half treads and shift the user's weight from side to side, thereby being able to climb the ladder even without holding on and, when holding on, the vertical grab rail portions may be used for counterbalance.
