ADJUSTABLE HEIGHT VEHICLE ROLL-OVER BAR Abstract of the Disclosure An adjustable height roll-over bar is provided in which the cross-piece is separate from the vertical members. The height of the roll-over bar is adjusted by adjusting the connection between the cross piece and the roll-over bar. The three embodiments for this connection are taught: First, corner brackets are provided and an extension can be added between the vertical member and the corner bracket to increase the height of the roll-over bar. One corner bracket leg is longer than the other to compensate for the difference in horizontal distance between the vertical member and the vertical member plus extension when the vertical members are angled. The same corner brackets can be used at either height simply by flipping the corner bracket end-for-end to adjust the position of the long leg. In the second embodiment, the vertical members and the cross piece each are provided with angled engagement surfaces, preferably 45 degrees. These surfaces can be engaged in a complimentary fashion so that the vertical members align with the U-shaped cross piece and provide maximum height. Alternatively, the cross piece can be flipped end-for-end so that the cross piece extends at an angle from the vertical members, preferably rearwardly at about 90 degrees. These surfaces are provided with matching knobs and depressions to prevent motion therealong and a bolt or other engagement means is provided to hold the two surfaces together. In the third embodiment, the cross piece is pivotally mounted to the vertical members. While the vertical members can be angled slightly relative to one another, the pivot surface on the two hinges is parallel. The U-shaped cross piece is pivotal between a maximum height position parallel to the vertical members and one extending rearwardly therefrom at a lower height. A quick release pin is provided to hold the cross piece in either of these positions.
