Adjustable height vehicle roll-over bar
First Claim
1. An adjustable roll-over bar comprising:
- two substantially vertical members angled slightly towards one another;
a substantially horizontal cross-piece;
two extensions, each extension being selectively connectible to a corresponding one of said vertical members; and
two corner pieces, each corner piece having two legs, with one of said legs being connectible to an end of said cross-piece and the other of said legs being connectible to one of said extensions if said extensions are connected to said vertical members and to an upper end of one of said vertical members if said extensions are not connected to said vertical members, one leg of each corner piece being longer than the other leg by an amount sufficient to compensate for the difference in horizontal distance between the tops of said vertical members and the tops of said extensions when positioned on the vertical members.

Abstract
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 degress. 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.

6. An adjustable roll-over bar comprising:
-
two substantially vertical members, the upper ends of which terminate in a plane angled relative to the plane of the ends of the vertical members; a cross-piece connecting the tops of said vertical members and having surfaces angled relative to the plane of the ends of the cross-piece; and means for selectively attaching said angled surfaces of said vertical members and said cross-piece so that said plane of the ends of the vertical members and said cross-piece are aligned or so that they are angled relative to one another. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
