  • Patent number: 4140230
    Abstract: A powered loading platform for mounting upon opening-defining walls of a vehicle to facilitate loading of objects, such as wheelchairs, from the ground into the interior of the vehicle and including support means which pivotally supports a horizontal platform and is carried by a powered parallelogram linkage which moves the support means in an arc between a lowered and outwardly disposed position upon the ground and an inwardly disposed elevated position within the body of the vehicle. Upon reaching the elevated position, the wheelchair may be rolled into the interior of the vehicle and the platform may be collapsed and then pivoted to a vertically extending position entirely within the confines of the vehicle. The support means is pivotable about a vertical axis to permit the collapsed platform to be then swung to non-blocking position relative to the vehicle opening.
