Wheel chock handling unit

A wheel chock handling unit for use with a wheel chock, the wheel chock handling unit including:

• a base;
• an articulated cantilever arm assembly having opposite first and second ends, the first end being pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position, the arm assembly comprising:
• a proximal arm;
• and
• a distal arm;
• the proximal arm having opposite top and bottom ends and the distal arm having opposite top and bottom ends, the first end of the arm assembly corresponding to the bottom end of the proximal arm and the second end of the arm assembly corresponding to the bottom end of the distal arm;
• the proximal and distal arms being pivotally connected for pivoting the distal arm about a pivot axis perpendicular to the vertical plane;
• a pivoting assembly comprising:
• a first member configured to be secured to the distal arm, having a top end and a bottom end and a longitudinal axis extending therebetween;
• and
• a second member configured to be secured to the first member at a first position that is offset from the top end of the first member along the longitudinal axis, and configured to be pivotally connected to the proximal arm;
• a main spring assembly extending between the arm assembly and the base.

A wheel chock handling unit for use with a wheel chock, the wheel chock handling unit including:

• a base;
• an articulated cantilever arm assembly having opposite first and second ends, the first end being pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position;
• wherein the arm assembly includes a proximal arm and a distal arm that are operatively connected at an upper joint, the proximal arm having opposite top and bottom ends and the distal arm having opposite top and bottom ends, the first end of the arm assembly corresponding to the bottom end of the proximal arm and the second end of the arm assembly corresponding to the bottom end of the distal arm;
• wherein the upper joint is configured to allow pivotal movement of the distal arm with respect to the proximal arm about a pivot axis;
• a pivoting assembly laterally offset from the pivot axis of the arm assembly comprising:
• a first member secured to the distal arm;
• and
• a second member secured to the proximal arm and pivotally connected to the first member;
• and
• a main spring assembly extending between the arm assembly and the base and configured to exert a force above the upper joint for causing pivotal movement of the distal arm about the pivot axis.
