Luggage with Large Storage Capacity

Abstract

A luggage includes a case, four wheels mounted on a bottom of the case, and a handle connected to the case. The case includes a case member and a lid. The case member is a single element having an opening at a front thereof to be an entrance of a chamber therein. The lid is pivoted on the case member to open and close the opening of the case member. The case member is provided with first reinforced ribs on a back side, and second reinforced ribs on a left side and a right side. The first reinforced ribs are perpendicular to the second reinforced ribs to enhance the strength of the case member.
