ABSTRACT:
A folding framework (18) for a ramp section (12) includes folding legs (20). The legs include extendable members (24) extending between the sets of legs with an inner sliding member (28) and a outer sliding member (26) providing for folding motion. The sets of legs (20) both fold inward to a storage position wherein extendable members (24) and the legs (20) lie substantially flat against the underside of a supportive deck (14). The extendable members (24) include an angled end portion (32) which extend downward and pivotally mount to the legs (20) for offsetting the extendable members (24) from the legs (20) when in the folded position.
