Abstract

A ladder having rungs (2) extending between two stiles (1) and being fixed to the stiles by means of end parts of the rungs passing through respective holes and the stile. The inner face (3) of a stile (1) and the inner face of a rung (2) being so relatively profiled that, upon assembly, when the end part of the rung is offered into he respective holes (5) a progressively increasing annular portion of the perimeter of the leading peripheral edge of the rung end parts enters and engages within the hole. The relative peripheral shapes of the hole (5) and of the rung end part being such that the diameter of the part of the hole into which the rung (2) is initially fitted is at least as big as the corresponding diameter of the rung and the progressive engagement provides a tight fit between the rung end part and the stile.
