Abstract
An apparatus for establishing dynamic ground contact is disclosed. A ground contact tip is attached to one end of an elongate member. The ground contact tip contains a connecting portion and a base portion that is opposite the connecting portion. A flexible core connects between the base portion and the connecting portion. At least one limiting ring is positioned on the flexible core. The elongate member is permitted to rotate through a range of angles while the flexible core allows the base portion to remain flat against the ground. At the maximum allowable angle, the limiting rings allow the ground contact tip to cease flexing and become rigid, so that the user can push against the ground at an angle, while the base portion remains flat against the ground.
