Abstract
An apparatus for detecting the angle of inclination of a vehicle and for providing an alarm signal when the inclination of the vehicle exceeds a predetermined maximum safe level. An elongate, pliant tubular member made of an electrically conductive material has its intermediate segment mounted by an insulative clamp to a vertical panel which may be situated on the vehicle'"'"'s dashboard. The end segments of the tubular member are upwardly inclined, and the degree of inclination is shown by angular indicia on adjacent portions of the vertical panel. A plurality of spherical contact elements made of an electrically conductive material are positioned within the tubular member. A pair of contact points made of an electrically conductive material are inserted into the opposite ends of the tubular member. When the angle of inclination of the vehicle exceeds the safe level, the contact elements will strike one of the contact points. This causes an electric current from the vehicle'"'"'s battery to energize an indicator such as a buzzer which provides a warning signal.

means for mounting the intermediate segment of the tubular member to the panel with the end segments of the tubular member inclined upwardly; indicia on the panel for providing an indication of the degree of inclination of the end segments of the tubular member with respect to the intermediate segment of the tubular member; a pair of contact points made of an electrically conductive material inserted into the opposite ends of the tubular member; means for electrically insulating the contact points from the tubular member; a plurality of spherically shaped contact elements made of an electrically conductive material positioned within the tubular member and adapted to move longitudinally therein into contact with the contact points upon a predetermined degree of rotation of the vertical panel about an axis perpendicular to the panel; a quantity of a lubricant within the tubular member; electrical indicator means for providing a human perceivable warning signal upon energization; and electrical circuit means for connecting the tubular member, the contact points and the electrical indicator means to a source of electric current so that the electrical indicator means will be energized when the contact elements move into contact with the contact points; whereby when the vehicle exceeds a predetermined safe limit of inclination set by bending the end segments of the tubular member a predetermined amount upwardly with respect to the intermediate segment, the electrical indicator means will provide a warning signal, while jolting of the vehicle as it is driven over rough terrain will not cause a false alarm.
