Luggage case and case body structure thereof

Abstract

A case body structure of a luggage case includes a case top member, a case bottom member and a sidewall member that are independent components. Each of the case top member and the case bottom member is a hard structure. The sidewall member includes a wall plate and a cover plate. The wall plate includes a connecting section, two installation sections, and an installation breach defined and formed by the two installation sections. The cover plate is disposed correspondingly to the installation breach. The cover plate and the wall plate define a hollow cavity. The case top member and the case bottom member are respectively disposed at two ends of the sidewall member to enclose the hollow cavity. The cover plate selectively opens relative to the wall plate to allow an object to be placed into or taken out of the hollow cavity.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a luggage case and a case body structure thereof.BACKGROUND OF THE INVENTION[0002]To conveniently carry various objects for travelling or house moving, luggage cases are some of the first choices for loading objects. The most eye-catching part of a luggage case is the case body of the luggage case, which is much targeted by many consumers when a luggage case is chosen and purchased. Some main factors that consumers consider include the size and the outer appearance of the case body. For example, current luggage case structures are as disclosed by the Taiwan Patent Nos. 404193 and No. M332408, the China Patent No. 202456880, the U.S. Patent Publication No. 2014 / 0224608, and the European Patent No. 2873342A1, and have case bodies that are categorized based on the type of materials used. Current case body structures are chiefly categorized into two types—made of a textile fabric, and made of a plastic material in a formed int...

AI Technical Summary

Benefits of technology

The patent text discusses a new invention where the size and design of a case are determined by the size and pattern of the case bottom structure instead of the top surface or bottom surface. A case is made up of a case top member, case bottom member, and sidewall member that are independent components. This allows for the creation of universal parts for the case top and bottom members, reducing costs and waste during development and manufacturing. Only one-time molds need to be made for the case top and bottom members, which can be used in multiple products. This approach also improves market competitiveness.

Problems solved by technology

Luggage cases made of textile fabrics eliminate costs for developing and manufacturing molds, with however large amounts of manpower and textile machinery required as a trade-off, leading to overall costs that cannot be lowered due to manpower costs and disfavored mass production.

Further, for luggage cases implemented by plastic materials, although they can be mass produced once large sums of mold costs are invested at the beginning of the development and manufacturing process, the molds made are strictly limited to the use of one single product.

In the event of slow sales in the manufactured luggage cases, these molds become unsuitable and need to be discarded.

In addition, the manufacturer needs to invest another round of mold costs needed for a launching another product.

The cycle above may lead to not only increased costs for the manufacturer but also waste in resources.
