Description
- The present invention relates to a luggage case and a case body structure thereof.
- 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 integral.
- 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.
- Therefore, it is a primary object of the present invention to solve issues of a conventional luggage case manufacturing method.
- To achieve the above object, the present invention provides a case body structure of a luggage case. The case body structure of a luggage case includes a case top member, a case bottom member and a sidewall member. 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 respectively integrally extended from two opposite lateral sides of the connecting section and perpendicular to the connecting section, and an installation breach defined and formed by the two installation sections. The cover plate corresponds to the installation breach, and is disposed on the two installation sections. The cover plate and the wall plate define a hollow cavity. Each of the case top member, the case bottom member and the sidewall member is an independent component. 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.
- In one embodiment, the width of the connecting section of the wall plate is greater than the width of each of the installation sections, and the width of the installation breach is smaller than or equal to the width of the connecting section and greater than the width of each of the installation sections.
- In one embodiment, the wall plate includes a support element and a flexible outer layer clad on the support element. The flexible outer layer is assembled to the case top member and the case bottom member. Two ends of the support element are respectively abutted against the case top member and the case bottom member to cause the flexible outer layer to be tightened relative to the support element.
- In one embodiment, each of the case top member and the case bottom member includes an assembly groove for abutting and connecting with the sidewall member.
- In one embodiment, the flexible outer layer is selected from the group consisting of textile, nylon, leather and polyvinyl chloride (PVC).
- In one embodiment, the wall plate is a formed integral made of a hard plastic material.
- In one embodiment, the case body structure further includes at least two suture shutters. Each of the suture shutters is disposed at a seam of the case top member and the sidewall member or the case bottom member and the sidewall member, and includes a connecting portion being deep into the seam and a shutter portion integrally extended from the connecting portion and protruding out of the seam.
- The present invention further provides a luggage case, which applies one of the case body structures of the foregoing embodiments. The luggage case further includes a pull handle and a pull handle positioning module. The pull handle is assembled to the case body structure. The pull handle positioning module includes a support sleeve disposed on the case top member and causing the pull handle to be inserted therein and to be able to perform a back-and-forth movement, and a limiting element disposed in the support sleeve and limiting or allowing the pull handle to perform the back-and-forth movement relative to the support sleeve.
- In one embodiment, the case top member includes an installation opening in communication with the hollow cavity and allowing the support sleeve to be correspondingly disposed therein. The support sleeve is further located in the hollow cavity.
- In one embodiment, the luggage case further includes a plurality of rollers disposed on the case bottom member. The case body member includes a plurality of assembly holes, which are in a quantity corresponding to the rollers and are respectively assembled with the rollers.
- In one embodiment, the pull handle includes an outer tube assembled to the case body structure, and an inner tube inserted in the outer tube and capable of stretching and retracting relative to the outer tube.
- Through the above technical solution, the present invention provides following features as opposed to the prior art.
- The Applicant of the application considers that the size as well as the outer appearance and design are determined by the size and pattern of the case body structure instead of the design of a top surface or a bottom surface of the case body structure. Therefore, in the present invention, the case body structure is formed by the case top member, the case bottom member and the sidewall member that are independent components. During development and manufacturing, only one-time molds need to be made for the case top member and the case bottom member and may serve as universal parts. Thus, when a new product is developed, only the mold for the sidewall member needs to be manufactured, hence reducing unnecessary waste and development and manufacturing costs as well as enhancing market competitiveness.
