Claim 0:
1. A boom arm assembly comprising:
a main boom;
a boom tip configured to assume a neutral position and to pivot to a forward position, a rearward position, and an upward position relative to the main boom;
an upper ball joint connecting the main boom to the boom tip;
a first hinge connected to the main boom, the first hinge having a first hinge axis defined between the upper ball joint and the first hinge;
a second hinge connected to the boom tip, the second hinge having a second hinge axis defined between the upper ball joint and the second hinge;
a hinge connecting bar connecting the first hinge to the second hinge;
a first hinge seat attached to the main boom and having a resilient insert shaped to fit about a first portion of the hinge connecting bar;
a second hinge seat attached to the boom tip and having a resilient insert shaped to fit about a second portion of the hinge connecting bar; and
a spring assembly connecting the boom tip to the main boom at a second ball joint, the spring assembly comprising a first spring and an elongated rod, wherein the first spring applies a holding force on the boom tip toward the main boom such that the spring assembly provides a break-away threshold;
wherein the boom tip is movable relative to the main boom about the first hinge axis, the second hinge axis, and a pivot point defined by the upper ball joint when the break-away threshold is exceeded;
wherein the first spring urges the boom tip toward the neutral position relative to the main boom when the boom tip is not in the neutral position.
