  • Patent number: 8931792
    Abstract: A staircase for a vehicle with a rigid frame attached to a rigid bed connector that is attachable to the bed of a vehicle. The bed connector is pivotably attachable to the bed so that the connector can be rotated between a stowed position in which the connector is above the bed and a deployed position in which the connector extends behind the vehicle bed. The frame is rotatably attached to the bed connector so the frame is rotatable between a deployed position in which an end of the frame rests on the ground and a retracted position in which the frame is parallel to the bed. The bed connector is then rotatable to bring the staircase to stowed position above the vehicle bed. A plurality of steps are attached to the staircase frame so that a user can walk up the stairs and onto the vehicle bed.
