Abstract
An access device for providing access between a lower substrate surface and an upper substrate surface. The access device includes upper and lower articulated ladder members. A first end of the upper member is pivotally connected to or near the upper surface. A second end of the lower member is pivotally connected to the second end of the upper member, such that the lower ladder member is rotatable 180° relative to the upper member. In the storage position, the ladder members are folded in a substantially compact upright disposition, while, in the access position, the members are aligned and extend downwardly and outwardly.
