Suitcase

Abstract

This design relates to a suitcase, particularly a suitcase with a variable size. The storage part of the suitcase can be separated into three cylindrical storage parts. Wheels are provided at the lower edge of the upper storage part, and concave rib grooves that fit with the wheels are formed at the upper edge of the middle storage part facing the upper storage part. Wheels are provided at the lower edge of the middle storage part, and concave rib grooves are formed at the upper edge of the lower storage part facing the middle storage part. As shown in Reference Figure 1 showing the usage state, each storage part can be inserted and fitted from the lateral direction. When forming a large-capacity suitcase, all the upper, middle, and lower storage parts are used. As shown in Reference Figure 2 showing the usage state, when forming a small-capacity suitcase, the upper and lower storage parts are fitted together.
