Front bumper step for trucks

An adjustable, temporary step for mounting on the front bumper of heavy-duty motor vehicles such as trucks and buses, said step comprising:

• a. a pair of widely spaced, parallel, L-shaped structural members, each L-shaped member being formed of hollow square tubing and having a generally horizontal support arm and a generally perpendicular, raised vertical post;
• b. a platform panel attached across the two support arms;
• c. each vertical post being provided with a pair of vertically spaced through bolts that are adjustably mounted to the post, the top bolt having a down-turned hook formed on its outermost end and adapted for engagement over a top flange of a bumper, while the bottom bolt has a non-mar fitting formed on its outermost end and adapted for engagement with a front wall of a bumper, each pair of vertically spaced through bolts having threaded shanks, and each post having enlarged holes for loosely receiving the pair of bolts therethrough, the top bolt being fitted with an enlarged hand-turnable nut on its free end;
• and
• d. a horizontal, elongated, adjustable rod for making a quick connection betwen the two bottom bolts and the related vertical posts, each vertical post also having side through holes on opposite sidewalls of the post and being in the same horizontal plane as the adjacent enlarged holes through which the bottom bolts extend, the elongated adjustable rod extending completely through each side through hole of each post from one post to the other, the portion of the elongated rod within each hollow post being provided with an elongated hole for receiving the threaded bottom bolt therein with a slip fit, one end wall of each elongated hole being provided with a concave, semicircular, threaded configuration for locking engagement with the threads of the adjacent bottom bolt when the rod is shifted into engagement therewith, the opposite end wall of each elongated hole being provided with an enlarged portion for permitting free axial movement of the bottom bolt, and a compression spring fitted on the elongated rod and bearing against at least one post for shifting the elongated rod into locking engagement with the two bottom bolts whereby the position of the bottom bolts may be altered after the elongated rod has been shifted against the action of the compression spring.
