Vehicular wheelchair step lift

A wheelchair step lift for used in conjunction with a vehicle having an opening and a floor opening, the lift comprising:

• a. a housing being mountable to a floor of said vehicle and located on opposite sides of said floor opening;
• b. a frame mounted to said housing for vertical movements and located adjacent to said floor opening;
• c. a platform structure mounted to said frame and having a plurality of individual plates which are rotatably connected at their adjacent edges, wherein the individual plates are manually folded from an outermost individual plate against an adjacent individual plate to an innermost individual plate for stowing the platform structure into a step position of said vehicle and manually unfolded inversely for use, and means for preventing a wheelchair from rolling-off said platform structure before said platform structure reaches a ground level position, the means including a roll-stop plate rotatably connected to a free edge of said outermost individual plate, and manually folded for stowing, and manually unfolded to a vertical position for preventing the wheelchair from rolling-off said platform structure, the roll-stop plate having two pairs of opposite adjacent protruding flanges, wherein one pair of protruding flanges are secured to said outermost individual plate and the other pair of protruding flanges are movably secured to notches on said outermost individual plate for maintaining said roll-stop plate in the vertical position.

A wheelchair step lift for used in conjunction with a vehicle having a door opening and a floor opening, the lift comprising:

• a. an elevator housing being mountable to a floor of said vehicle and located on opposite sides of said floor opening;
• b. an elevator frame mounted to said elevator housing for vertical movements and being located above said floor opening;
• c. a platform structure mounted to said elevator frame and having an inner plate, a middle plate and an outer plate, which are all rotatably connected at their transverse adjacent edges, wherein the outer plate is manually folded against the upperside of the middle plate which in turn the outer and middle plates are manually folded against the upperside of the inner plate for stowing the platform structure in a step position of said vehicle, and manually unfolded inversely for use in an entry level position;
• and
• d. a roll-stop plate rotatably connected to a free transverse edge of said outer plate and manually folded for stowing, and manually unfolded to a vertical position for preventing a wheelchair from rolling off said platform structure before said platform structure reaches a ground level position, the roll-stop plate having two pairs of opposite adjacent protruding flanges, wherein one pair of protruding flanges are secured to said outer plate and the other pair of protruding flanges are movably secured to notches on said outer plate for maintaining the roll-stop plate in the vertical position.
