  • Patent number: 4620609
    Abstract: A removable bumper step for vehicles comprises a rigid plate having an upper, generally planar foot supporting surface terminating in a front end. The front end bends into a hook formation and is adapted to engage the upper edge of a vehicle bumper when the plate is positioned horizontally over the upper surface of the bumper. Means engaged with the plate adapt to contact the upper surface of the bumper rearwardly of the hook formation. The hook formation and means cooperate to maintain the plate in a horizontal attitude under the weight of a user. Varying vehicle bumper widths are accommodated by adjusting the means relative to the plate. Friction enhancing material adheres respectively to the foot supporting surface and the means. This material provides secure footing for a user, and stabilizes the engagement of the step to the vehicle bumper.
