ABSTRACT:
A wheelchair lifting platform device for raising or lowering of a wheelchair into or out of a vehicle. The invention includes a barrier safety mechanism which is connected to a wheelchair platform. The barrier safety mechanism includes a barrier plate and an activator flipper plate. The barrier plate extends vertically from, and is positioned substantially perpendicular to, a foldable platform during the raising or lowering of a wheelchair. The barrier plate functions as a safety stop prohibiting the inadvertent rolling of a wheelchair off of the platform. The activator flipper plate is pivotally connected to the platform and to the barrier plate. The activator flipper plate functions to engage a road surface as the platform is lowered, for retraction of the barrier plate as the activator flipper plate engages the ground. The invention additionally includes a latching mechanism for coupling a foldable wheelchair platform to the frame of a wheelchair lift device. The improved latching mechanism includes a slide having a handle, and a notch having an engagement lip. The manipulation of the handle releasably couples the notch and lip to an engagement pin mounted to the frame of a wheelchair lift device.
