Suitcase with Retractable Handle Assembly

Abstract

A suitcase includes a main body and a retractable handle assembly. The handle assembly includes a pair of outer handles and at least one pair of inner handles. Each of the inner handles and the outer handles is made of a plastic pipe which is formed by a primary material which is fused, extruded and molded to form the plastic pipe of each of the inner handles and the outer handles. The primary material includes polymethyl Methacrylate (PMMA), polycarbonate (PC) or polyethylene terephthalate (PET). Thus, the handle assembly has a better outer appearance and has a lighter weight. In addition, each of the inner handles and the outer handles has a better restoring function and can be rapidly restored to the original state when being deformed due to a collision.
