Abstract
Abstract A vehicle bumper step formed by an upwardly open frame having clamp members secured to its upper surface for mounting the frame on a vehicle bumper by gripping a bumper flange. Longitudinally adjustable arms, connected with the frame, project toward a vertical surface of the bumper for stabilizing the position of the frame relative to the bumper. A step having a tread portion is movable from a first position nested by the frame to a second position projecting horizontally beyond the bumper in a direction outwardly from the vehicle and includes a hook portion engaging the frame normally preventing separation of the step relative to the frame.

Claim 1
Independent Claim
212 words
A retractable step for a vehicle bumper having a generally vertical portion and upper and lower laterally projecting flanges normal to the plane of said vertical portion, the improvement comprising: an upwardly open frame having forward and rearward ends and having lateral sides spaced longitudinally of said bumper; clamp means secured to the upper limit of said frame adjacent its respective sides for gripping one said bumper flange, said clamp means comprising a clamp member projecting outwardly from said frame and doubled back upon itself to describe a U-shape having parallel legs, and, a stud bolt projecting through one said leg normal to the plane thereof; arm means connected with said frame and projecting toward said bumper in the direction of said clamp means for stabilizing the position of said frame relative to said bumper, said arm means comprising an elongated arm, a stub arm overlapping the end portion of said arm opposite said frame and having a longitudinal slot therein, and, bolt means securing said stub arm to said elongated arm; a step movable from a first position nested by said frame to a second position projecting beyond and normal to the vertical portion of said bumper; and, hook means for normally preventing separation of said step relative to said frame.

Claim 4
Dependent Claim
200 words
A retractable step for a vehicle bumper having a generally vertical portion and upper and lower laterally projecting flanges normal to the plane of said vertical portion, the improvement comprising: an upwardly open frame having vertical forward and rearward end members and having lateral sides spaced longitudinally of said bumper, said frame end members having a rabbeted edge adjacent their upper limit; clamp means secured to the upper limit of said frame adjacent its respective sides for gripping one said bumper flange; arm means connected with said frame and projecting toward said bumper in the direction of said clamp means for stabilizing the position of said frame relative to said bumper; a step movable from a first position nested by said frame to a second position projecting beyond and normal to the vertical portion of said bumper, said step having side rails each having a notch formed in one edge surface for cooperative engagement with said rabbeted edge and preventing separation of said step relative to said frame when said step is in said second position; and, a lug secured to the upper limit of said frame and overlapping an edge portion of said step when in said second position.
