Abstract
A wheelchair ramp assembly (10) is disclosed as including a first ramp section (22) and a second ramp section (24) joined by a keyway joint (26). The keyway joint (26) connects the two ramp section (22, 24) surfaces when the ramp is in an extended position. The keyway joint (26) includes a first ramp section outer rotating member (64a) and a second ramp section outer rotating member (64b) that each rotate about an inner member (68). The inner member (68) is configured to limit the rotation of the outer members (64) with respect to one another, thereby limiting the rotation of the first ramp section (22) with respect to the second ramp section (24).
