Abstract
A wheel-chocking device including a base member and a collapsible chock movable between lowered and raised positions. The chock includes a chocking member movable relative to the base member, and support members pivotably attached to the chocking member and defining therewith pivot axes, the pivot axes and the chocking member being movable between a substantially horizontal orientation and an inclined orientation. The chocking member and the support members are substantially coplanar when the chock is in the lowered position. The chocking member and the support members are inclined and the chocking member is substantially perpendicular to the support members when the chock is in the raised position. The base member has a longitudinal axis defining a vertical plane, and the pivot axes are substantially parallel to the vertical plane. The wheel chocking device also has a support member guide system including a first guide affixed to the base member for directing a support member toward the inclined orientation as the chocking member moves in a first direction, and a second guide affixed to the base member for directing a support member toward the horizontal orientation as the chocking member moves in a second direction opposite the first direction.
