Abstract
The present invention provides a significant improvement to a ladder by making it light-weight and easily collapsible. Ladder rails slide back and forth over ladder rungs allowing the ladder to collapse to a fraction of its extended size. After collapse of the rails, the rungs fold up using a pivoting knuckle hinge. The pivot is specifically designed to pivot only one way to prevent accidents or collapse while the ladder is in use. This design allows the ladder to be compact and easily transportable. Similarly, the materials used to construct the ladder make it light-weight enough for most adults to carry easily.
