Description

    FIELD OF THE INVENTION
  • The present invention relates to a luggage case and a case body structure thereof.
  • BACKGROUND OF THE INVENTION
  • 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.
  • SUMMARY OF THE INVENTION
  • Therefore, it is a primary object of the present invention to solve issues of a conventional luggage case manufacturing method.

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.

  • 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.

  • Details and technical contents of the present invention are given with the accompanying drawings below.
  • Referring to FIG. 1 to FIG. 3, the present invention provides a luggage case and a case body structure thereof. The case body structure 1 includes a case top member 11, a case bottom member 12 and a sidewall member 13. Each of the case top member 11, the case bottom member 12 and the sidewall member 13 is an independent component. That is, the case top member 11, the case bottom member 12 and the sidewall member 13 are individually manufactured, and are not a formed integral. Further, each of the case top member 11 and the case bottom member 12 is a hard structure, which may be made of a plastic material such as polypropylene (PP), polycarbonate (PC) or polyethylene terephthalate (PET). The case top member 11 or the case bottom member 12 may be a formed integral made by machinery processing. The case top member 11 and the case bottom member 12 may be corresponding structure designs based on actual requirements to bear an expect load weight, so as to prevent the case top member 11 or the case bottom member 12 from deformation during a weight bearing process.
  • The sidewall member 13 includes a wall plate 14 and a cover plate 15. The wall plate 14 in overall appears substantially U-shaped, as shown in FIG. 4. The wall plate 14 includes a connecting section 141, two installation sections 142 respectively integrally extended from two opposite lateral sides of the connecting section 141 and perpendicular to the connecting section 141, and an installation breach 143 defined and formed by the two installation sections 142. Further, the wall plate 14 may be designed with at least one recessed pattern or protruding block according to esthetic requirements. The cover plate 15 corresponds to the installation breach 143 and is disposed on the two installation sections 142, and the cover plate 15 and the wall plate 14 define a hollow cavity 16 when assembled. Two ends of the hollow cavity 16 are not shielded and appear as a through formed. That is, when not assembled to the case top member 11 and the case bottom member 12, the sidewall member 13 appears as a through form with two open ends. To assemble the case body structure 1, the case top member 11 and the case bottom member 12 are respectively disposed correspondingly to the two open ends of the sidewall member 13 to enclose the two ends of the sidewall member 13, thereby completing the case body structure 1 of the present invention. Further, the cover plate 15 is assembled to the wall plate 14 by a zipper (not shown), such that the cover plate 15 may selectively open or close relative to the wall plate 14. When the cover plate 15 opens relative to the wall plate 14, an object may be placed into or taken out of the hollow cavity 16.
  • Referring to FIG. 4, in the present invention, the width of the connecting section 141 of the wall plate 14 is greater than the width of each of the installation sections 142, and the width of the installation breach 143 is smaller than or equal to the width of the connecting section 141 but greater than the width of each of the installation sections 142. For example but not limited to, the wall plate 14 and the cover plate 15 may be implemented by a hard plastic material. In one embodiment, the wall plate 14 includes a support element 144 and a flexible outer layer 145 clad on the support element 144. The flexible outer layer 145 has an appropriate flexibility to be appropriate stretched, and is selected from the group consisting of textile, nylon, leather and polyvinyl chloride (PVC).

When two ends of the support element 144 are respectively abutted against the case top member 11 and the case bottom member 12, the case top member 11 and the case bottom member 12 are spaced by a distance, owing to which the flexible outer layer 145 is caused be tightened relative to the support element 144. Further, when the flexible outer layer 145 is tightened, the case top member 11 and the case bottom member 12, under the effect of the flexible outer layer 145, are more stably pressed upon the support element 144, such that better assembly effects among the components of the case body structure 1 are achieved.
  • In the present invention, since the sidewall member 13 is not a formed integral with the case top member 11 or the case bottom member 12, a manufacturer or a consumer may select different patterns or materials for the sidewall member 13 according to designs or preferences. Further, with the present invention, a manufacturer is required to only replace the mold of the sidewall member 13 when launching a new product, hence innovating a conventional implementation of replacing an entire set of molds for a new product when a manufacturer launches the new product.
  • In one embodiment, respective ends of the case top member 11 and the case bottom member 12 predetermined to be assembled to the sidewall member 13 are provided with assembly grooves 111 and 121 for abutting and connecting with the sidewall member 13. The assembly grooves 111 and 121 may further surround the case top member 11 or the case bottom member 12. However, in an assembly process, the sidewall member 13 may be assembled to the case top member 11 and the case bottom member 12 by aligning with the assembly grooves 111 and 121. As such, the sidewall member 13 is substantially positioned to effectively support the case top member 11 and the case bottom member 12.
  • Referring to FIG. 5, in the present invention, the fastening between the case top member 11 or the case bottom member 12 and the sidewall member 13 may be achieved through a stitching method. As known from foregoing embodiments, only after the flexible outer layer 145 is assembled to the case top member 11 and the case bottom member 12, the sidewall member 13 is then assembled to the support element 144. The flexible outer layer 145 may be assembled to the case top member 11 and the case bottom member 12 through stitching (as shown by the stitching position 20 in FIG. 5), and the assembly of the support element 144 may then be performed after the flexible outer layer 145 is completely assembled.
  • Referring to FIG. 6, in another embodiment, the wall plate 14 may be implemented by a hard structure, and after the case top member 11 or the case bottom member 12 is assembled to the sidewall member 13, an overlapping region of the two components assembled to each other may be stitched to produce a securing effect. To more substantially implement stitching, the thickness of the sidewall member 13 of the present invention is selected to meet an appropriate support strength and to be within a range that can be stitched. Further, the stitching position of the case top member 11 or the case bottom member 12 may also be correspondingly designed to facilitate the implementation of stitching. Further, to optimize the esthetic appearance after the stitching process, the case body structure 1 further includes at least two suture shutters 17. Each of the suture shutters 17 is disposed at a seam 21 of the case top member 11 and the sidewall member 13 or the case bottom member 12 and the sidewall member 13, and includes a connecting portion 171 being deep into the seam 21 and a shutter portion 172 integrally extended from the connecting portion 171 and protruding out of the seam 21. During the implementation of the stitching process, while the case top member 11 (or the case bottom member 12) is aligned with the sidewall member 13, the connecting portion 171 of the suture shutter 17 is correspondingly placed at the seam 21 between the case top member 11 (or the case bottom member 12) and the sidewall member 13, such that the shutter portion 172 protrudes from the seam 21 and is revealed at an outer side of the sidewall member 13. The case top member 11 (or the case bottom member 12), the connecting portion 171 of the suture shutter 17 and the sidewall member 13 are stitched to secure the three through stitching. Then, the shutter portion 172 is used to cover the stitched positions to polish the overall appearance of the case body structure 1. Further, in the present invention, each of the suture shutters 17 is a formed integral made from a soft plastic material. Further, the technical solution of implementing the suture shutters 17 may be applied to the embodiment of the wall plate 14 including the support element 144 and the flexible outer layer 145, with associated details shown in FIG. 7.
  • Again referring to FIG. 1 to FIG. 3, in addition to the foregoing case body structure 1, the present invention further discloses a luggage case 9. The luggage case 9 applies the case body structure 1 disclosed in the abovementioned embodiments, and further includes a pull handle 3 and a pull handle positioning module 4. The pull handle 3 is assembled with the case body structure 1. The pull handle positioning module 4 includes a support sleeve 41 disposed on the case top member 11, and a limiting element (not shown) disposed in the support sleeve 41. The support sleeve 41 may be installed at an outer edge of the case top member 11 or inside the hollow cavity 16. Further, the case top member 11 may include an installation opening 113 in communication with the hollow cavity 16 and allowing the support sleeve 41 to be correspondingly disposed at an inner edge of the case top member 11. Further, the support sleeve 41 allows the pull handle 3 to be installed therein, such that the pull handle 3 is capable of performing a back-and-forth movement relative to the support sleeve 41, i.e., the pull handle 3 is capable of performing drawing and pulling operations relative to the support sleeve 41. Further, apart from being disposed in the support sleeve 41, the limiting element further allows the pull handle 3 to be inserted and disposed therein, or limits or allows the pull handle 3 to perform the back-and-forth movement relative to the support sleeve 41.
