Abstract
A breakaway joint for a boom arm assembly includes a first boom segment defining a pivot axis at a first end, a second boom segment pivotally coupled to the first boom segment at the pivot axis, a bracket coupled to the first boom segment, a leaf spring coupled to the bracket between the first boom segment and the second boom segment, and a cam coupled to the second boom segment and positioned adjacent to the leaf spring. The first boom segment and the second boom segment are pivotally aligned in a neutral position. In the neutral position, the leaf spring contacts the cam at a first contact force, and in any position other than the neutral position, the leaf spring contacts the cam at a contact force greater than the first contact force.
