Rolling Tube Cradle with Elastic Retention

A spring-supported rolling tube assembly, comprising:

• a tube cradle and spring support member including opposing cradle walls, upstanding cradle arms, a base, cradle vents, and a plurality of axle snap-in retention features;
• a snap-in axle with spring support member including opposed axle arms, axle channels, snap-in pockets, axle bends, and axle wheel support lugs;
• a plurality of wheels mounted to the axle wheel support lugs;
• at least one spring positioned between the tube cradle and spring support member and the snap-in axle with spring support member;
• and
• an elastic band routed through the cradle vents and coupled to the upstanding cradle arms to retain a tube,
• wherein the snap-in axle with spring support member is elastically snapped into the tube cradle and spring support member, and wherein the at least one spring provides resilient load absorption during rolling movement of the tube.

A modular rolling tube system, comprising:

• a cradle with axle snap-in retention feature including opposing cradle walls, upstanding cradle arms, cradle vents, axle snap-in retention features, and spring holder snap-in retention features;
• a snap-in axle including opposed axle arms, axle channels, snap-in pockets, axle bends, and wheel support lugs;
• a plurality of spring holders selectively snapped to at least one of the cradles or the snap-in axle;
• a plurality of springs supported by the spring holders;
• a plurality of wheels mounted to the snap-in axle;
• and
• an elastic band routed through the cradle vents and coupled to the upstanding cradle arms to secure a tube,
• wherein the cradle, snap-in axle, spring holders, and springs cooperate to form a spring-supported rolling structure that retains the tube without puncturing the tube and permits selective detachment of the tube.
