    Patent number: 4806062
    Abstract: A forward platform section is hingedly connected at its forward edge to lower ends of a pair of runner assemblies that are vertically movably mounted in guides of a supporting framework. A closed rear edge of the forward platform section is hingedly interconnected to a closed forward edge of a rear platform section, the hinge connection being adapted for folding an underside of the rear platform section into superposition over an underside of the forward platform section. The curb side runner assembly incorporates a power cylinder for rotating the forward platform section between vertical and horizontal positions. A known linkage effects rotation of the rear platform section between vertical and horizontal positions as a function of corresponding rotation of the forward platform section.
