Light Transport Vehicle

A transport vehicle comprising:

• a vehicle frame having a lower chassis supporting and pivotally connected to an upper frame adjacent front ends of the lower chassis and the upper frame respectively, the lower chassis operatively supporting a transportation apparatus;
• first and second connection linkages operatively connected to rear end of the upper frame and rear end of the lower chassis respectively, wherein each of the connection linkages allows simultaneous movement about at least two non-parallel and non-intersecting axes, such that, one of the axis is rotatable about the other axis;
• and,
• a support frame operably connected between the first and the second connection linkages, the support frame including an upper member and a lower member each having a first end and a second end;
• wherein:
• the first ends are connected to one another via a folding connector allowing the upper support member to pivot toward the lower support member, and,
• the second ends are each rotatably and pivotally connected to the upper frame and the lower chassis respectively via the connection linkages such that:
• the second end of the lower member can both rotate about the lower chassis about a first axis and pivot relative to the lower chassis about a second axis;
• wherein the first and second axes are not parallel nor intersecting;
• and,
• the second end of the upper member can both rotate about the upper frame about a third axis and pivot relative to the upper frame about a fourth axis;
• wherein the third and fourth axes are not parallel nor intersecting;
• such that
• the upper frame and the lower chassis are displaceable between an extended position and a collapsed position, and the support frame folds in a lateral orientation with respect to the lower chassis and the upper frame.

A transport vehicle hitch for operatively connecting a tow bar of a transport vehicle to a bicycle and enabling simultaneous rotation of the tow bar about three non-parallel axes in relation to the bicycle;

• the hitch comprising:
• a hitch link including a rear end connectable to the tow bar, a front end formed as a ball and an intermediate portion extending therebetween;
• a hitch socket formed to retain the ball of the hitch link, the hitch socket having a front end;
• a rear end;
• a slot extending about the rear end of the hitch socket;
• and a first pivot connector, the front end of the hitch socket having an opening sized to permit the ball of the hitch link to pass therethrough and the rear end of the hitch socket is formed to retain the ball of the hitch link, wherein the assembly of the hitch link and the hitch socket enables pivotal movement of the hitch link in relation to the hitch socket about a first and second axes;
• a bicycle link for attachment to a bicycle frame, the bicycle link including a second pivot connector releasably connectable to the first pivot connector allowing the hitch socket to pivot in relation to the bicycle link about a third axis.

An adjustable suspension system for a transport vehicle having a vehicle frame and a transportation apparatus, the adjustable suspension system comprising:

• a suspension body for operative connection to the vehicle frame;
• and,
• a pivot arm pivotally connected to the suspension body, the pivot arm having:
• i.- a first end for connection to the transportation apparatus;
• and,
• ii- a first suspension connector for connection with a main suspension member, the main suspension member having:
• a pivoting end for pivotal connection to the first suspension connector;
• and,
• a sliding end for sliding support and engagement within an adjustment track within the suspension body;
• the sliding end operatively connected to an adjustment lever for operative movement of the sliding end within the adjustment track;
• wherein movement of the sliding end within the adjustment track changes the relative angle of the main suspension member with respect to the first suspension connector such that movement of the pivot arm with respect to the suspension body requires a different force depending on the relative angle of the main suspension member with respect to the first suspension connector.
