Folding ladder especially for accessing vehicle roof rack or top box has rungs that fold inside U-section uprights

摘要

The ladder consists of square, rectangular or round-section rungs that have their ends pivoted by rivets or bolts to U-section uprights (2) so that the ladder can be folded to the width of two uprights with the rungs enclosed inside them. The height of the ladder can also be reduced by having the uprights in two halves, connected on one side by a hinge (4) and on the other by a fastening (5). A U-section panel with deep sides is fitted under an upper rung when the ladder is in use to prevent it folding or slipping.
