Suitcase

Abstract

This article is a suitcase equipped with casters at each of the four corners of the bottom surface, a telescopic handle at a position near the back on the upper surface, and handles on the upper surface and the right side surface respectively. Also, this article is provided with two vertical ribs on the right side and the left side of the front respectively. As a result, even when the front is placed facing downwards, the central part of the front does not touch the floor or the ground, making it difficult for the central part of the front to be damaged. The same applies to the back. Also, as shown in the reference drawing showing the shape of the ribs, each rib is formed in a symmetric mountain shape, the top of each rib is formed in a convex arc shape with a radius of 4.0 mm, and the bottom of each rib is formed in a concave arc shape with a radius of 14.2 mm. Furthermore, the top and the bottom of each rib are smoothly connected, the bottom of each rib and the plane adjacent to the rib are smoothly connected, and the bottoms of adjacent ribs are also smoothly connected. As a result, although the ribs are provided, it gives a soft impression to the viewer. Furthermore, this article is provided with two fasteners in parallel over the entire circumference of the upper surface, the right side surface, the left side surface, and the bottom surface. The fastener on the front side is for opening and closing the shell, and the fastener on the back side is for expanding the capacity. When the fastener on the back side is opened and the front shell and the back shell are separated, the capacity can be expanded as shown in the right side view in the expanded state etc.
