Underfloor extendible ramp for vehicles

摘要: The disclosure comprises a tray mountable under the floor of vehicle, which contains an extendible ramp mechanism. This mechanism and driving panel for ramp. is fulcrummed intermediate its ends on outer parallel arms extending from panel. Also in tray, as part mechanism, are pair toothed belts driven by reversible rotating motor, attached to retracting tray. Mounted reciprocating motor connected crank arm shaft having additional pivotally underside adjacent When fully extended, tilts so that inner end moved upwardly be flush with vehicle. Simultaneously, contacts ground. has side barriers spring into position when extended. These automatically folded against top surface angularly-mounted roller cammed at each barrier retracted
