CASE丨A draw-bar suitcase design 可以更换箱体的组合式拉杆箱设计

This is a modular draw-bar suitcase designed specially for the traveling youth group. In design, it makes a breakthrough in the structure of exist-ing draw-bar suitcases in that it is divided into two components--the roll-ing and support system made of the draw bar and the rollers, and the suit-case itself. The bottom rolling and support assembly provides an expand-able lateral support area by means of an extensible mechanism, able to provide 3-point latching to receive 20, 24, or 28-inch suitcase and capable of lateral length adjustment. Also, the process of draw-bar and roller assembling is saved during manufacturing and so the manufacturer saves cost in logistics and assembling related to draw-bars and rollers. On the matter of utilization, the user is allowed to select different suitcases to suit their traveling needs. On the issue of brand, due to the simpler manufacturer process of modular draw-bar suitcases, it is possible to provide soft or hard suitcase products such that the line of products may be enriched quickly.
