Abstract
A support structure includes a nose arranged to fit within a cavity of the wear member. The nose may include a front portion having a plurality of outwardly facing surfaces that may be angled with respect to a longitudinal axis of the nose at a first angle. The nose may also include a rear portion having two horizontally separated outwardly facing surfaces and two vertically separated outwardly facing surfaces. The horizontally separated outwardly facing surfaces and the vertically separated outwardly facing surfaces may be angled with respect to the longitudinal axis at a second angle that is different than the first angle. A first concave surface and a second concave surface may each be positioned on one of the vertically separated outwardly facing surfaces, may be disposed only in the rear portion and may be shaped to form an arc. A through-hole may extend between the two horizontally separated outwardly facing surfaces. Each hole of the pair of holes may be arranged to receive a locking pin, and the first and second concave surfaces may be positioned at least partially rearward of the pair of holes.
