Access device

A retractable access device for providing access between a substrate surface and an elevated surface of a vehicle, comprising,

• support means attached to or integral with said elevated surface,
• said access device including a pair of spaced first and second side members connected by a plurality of spaced steps extending from a lower end of said access device to an upper end thereof,
• a pair of rigid arms provided on each side member of said access device, each arm being pivotally connected at a first end thereof to said support means, and, at second end thereof to said side members,
• said first end of said first arm being pivotally connected to said support means at more upwardly and rearwardly position relative to said first end of said second arm, and, said second end of said first arm being pivotally connected to a more upward position on said respective side member relative to said second arm,
• whereby, said device is pivotally movable from a stable lower position to a stable upper position, such that, in said lower position, said access device is inclined at between 60.degree. and 76.degree. relative to a substantially horizontal substrate surface, and, said upper end of said access device is positioned substantially adjacent to and forwardly of said elevated surface, and,
• wherein, in said upper position, said access device is positioned substantially vertically or at a rearwardly inclined angle in a position which is upward and rearward of said elevated surface.
