STEP LADDER WITH RUNGS HAVING BENT FRONT FACES FOR IMPROVED LEG SUPPORT
A step ladder. Two side rails and two support legs are connected to a top cap. Two locking spreader bars are connected between the support legs. The locking spreader bars hold the two side rails at a side rail angle. Ladder rungs are rigidly connected to the side rails. At least one of the ladder rungs has a bend to form a bent rung front face. The bent rung front face has a bent rung front face angle that is less than the side rail angle. To use the step ladder, the user will stand on a ladder rung and rest at least one of his legs against a bent rung front face. The increased angle of the bent rung front face will provide comfortable support for the user. In a preferred embodiment, the bent rung front face angle is vertical at 90 degrees.
