Foldable storage device with a laminated structure and a central sewing pivot axis.

Abstract

The present invention provides a foldable storage device with a laminated structure having a central sewing pivot axis. [Solution] This storage device has a booklet-like structure in which multiple sheet-like members are laminated and sewn in the center, allowing each sheet-like member to rotate relative to the others using the sewn part as a pivot axis, and can be used as a wallet. As a result, multiple storage compartments can be sequentially opened like turning pages, and intuitive opening and closing operations are possible. Furthermore, because each leather part is arranged independently like a page, stored items can be organized and held on each surface, making it possible to manage cards, banknotes, and other stored items in an easily visible state. Conventional wallets generally have a structure in which storage members are fixedly connected, and structures in which multiple storage compartments are sequentially opened like the pages of a booklet have rarely been proposed. Therefore, there were limitations in the degree of freedom of the storage structure and the ease of operation during use.

Description

Technical Field

[0001] The present invention relates to a foldable portable storage device configured such that a plurality of sheet-like members are sewn along a center line to form a laminate, and each sheet-like member is relatively rotatable about the sewing portion as a rotation axis. Particularly, the present invention relates to a structure applicable to a wallet, a card case, or other portable storage devices having a structure that can be opened and closed like a booklet and capable of storing cards, banknotes, and other portable items.

Background Art

[0002] Conventionally, as portable storage devices such as wallets and card cases, Those having a two-fold structure or a three-fold structure are widely used. These storage devices are formed by a structure in which an exterior member and an interior member are bonded together, or a structure in which a plurality of storage members are stacked and sewn, and are configured to be able to store cards, banknotes, and other portable items. In addition, for the purpose of increasing the storage capacity, storage devices having pocket portions formed in a bellows shape are also known. However, in these conventional storage devices, a structure in which an exterior member and an interior member are fixedly coupled is common, and the method of deploying the storage portion and the opening / closing structure are relatively limited. On the other hand, in the field of bookbinding technology, a center-sewing structure is known in which a plurality of sheet-like members are laminated and sewn along their center lines so that each sheet-like member can be opened and closed like a page. However, there has been no example of applying such a rotation structure by center sewing to a portable storage device such as a leather wallet. Problems to be Solved by the Invention

[0003] The present invention relates to wallets, card cases, and other portable storage devices. In the conventionally widely used storage devices having a two-fold structure or a three-fold structure, a structure in which an exterior member and an interior member are bonded together, or a structure in which a plurality of storage members are fixedly coupled by sewing or the like is common. In conventional structures, designs in which storage components rotate relative to each other as they unfold are rarely employed, and portable storage devices with a structure that allows multiple storage compartments to be unfolded sequentially like the pages of a booklet were virtually unknown. Furthermore, many conventional storage devices are based on a folding or bellows structure, which limits the freedom of design in terms of the placement of storage compartments, structural design, and opening / closing mechanisms. Therefore, the present invention aims to provide a portable storage device that employs a booklet-like structure in which multiple sheet-like members are laminated and sewn together in the center, so that each sheet-like member can rotate relative to the others with the sewn portion as the pivot point, and in which the storage members can be sequentially unfolded like turning the pages of a booklet. This aims to realize a new unfolding structure different from conventional folding or bellows structures, improve the flexibility of the storage compartment layout design, and provide a structure that allows sequential access to multiple storage compartments.

[0004] To solve the aforementioned problems, this invention provides a portable storage device with a booklet-like structure in which multiple sheet-like members are laminated and sewn together in the center of the multiple sheet-like members, so that each sheet-like member can rotate relative to the others with the sewn portion as the pivot axis. Specifically, the portable storage device of this invention comprises an exterior member and a plurality of internal storage members. The aforementioned multiple internal storage members are formed in sheet form and are integrated by sewing them together along the center line while stacked on top of each other. The stitched section along the center line connects each of the internal storage members to one another and also functions as a pivot axis that allows each internal storage member to rotate relative to the stitched section. As a result, the multiple internal storage components can be opened and closed sequentially, like the pages of a booklet, allowing the user to access each storage compartment by turning the pages. Furthermore, each of the internal storage members may be optionally provided with storage compartments such as card storage compartments, banknote storage compartments, or pocket compartments. Furthermore, the exterior member is arranged to cover the outside of the plurality of internal storage members, and the portable storage device is configured to be foldable. Thus, according to this invention, a booklet-like structure formed by sewing multiple sheet-like members together in the center can be realized, which is different from conventional folding or bellows structures.

[0005] According to this invention, by adopting a saddle-stitched structure in which multiple leather parts are layered and sewn together in the center, a wallet that can be opened and closed like a booklet can be realized. This allows the user to sequentially unfold each compartment with a page-turning motion, enabling an intuitive opening and closing operation that differs from conventional wallets. Furthermore, because each leather part is arranged independently like a page, the contents can be organized and held on each surface, making it possible to manage cards, banknotes, and other stored items in an easily visible manner. Furthermore, since this invention is composed of a relatively simple structure in which multiple leather parts are sewn together in the center, it does not require complex internal components or numerous partition structures, thus simplifying the manufacturing process. Furthermore, the structure, which involves layering leather materials and integrating them with saddle stitching, allows for a lightweight wallet with overall flexibility, improving portability and storage capacity. Furthermore, the stitching in the central section serves a structural function while also acting as an aesthetic design element, creating a unique appearance not seen in conventional wallets through the combination of leather material and stitching thread.

[0007] The embodiments of this invention will be described below with reference to the drawings. It should be noted that this invention is not limited to the embodiments described below, and various modifications are possible without departing from its essence. The portable storage device according to this invention has a structure comprising an exterior member and a plurality of internal storage members. The exterior member is a sheet-like member that covers the outside of the entire storage container, and can be made of, for example, natural leather, synthetic leather, cloth, or other flexible material. The exterior component is positioned to cover the internal storage component from the outside when the storage container is closed, forming a booklet-like appearance and serving to protect the internal structure. The internal storage member is composed of multiple sheet-like members, which are arranged in a state where they are overlapping each other. The multiple internal storage members are then integrated by sewing them together in the center. The central sewing section connects multiple internal storage members to each other and also functions as a pivot axis that allows each internal storage member to rotate relative to the sewing section. This configuration creates a structure in which the multiple internal storage members rotate and unfold sequentially, like the pages of a booklet. Therefore, the user can sequentially unfold each storage compartment by turning a page-like motion and access the necessary storage compartment. Each internal storage component can be provided with various storage compartments depending on the items to be stored. For example, it is possible to create compartments for storing cards, banknotes, pockets, small items, etc. These storage parts may be formed by sewing a leather piece or the like separate from the internal storage member, or may have a structure formed by folding back the internal storage member itself. Also, the number of internal storage members is not particularly limited and can be appropriately set according to the storage capacity and usage. For example, by laminating a plurality of leather parts and sewing the central part, a structure that can be opened and closed like a booklet can be formed. For the sewing of the central part, waxed thread, hemp thread, polyester thread, or other sewing threads can be used, whereby each member can be firmly connected. Furthermore, the exterior member may have a structure for holding the storage tool in a closed state by providing closing means such as buttons, hooks, belts, magnets, etc. With the above configuration, the portable storage tool of the present invention has a booklet-like structure formed by sewing a plurality of sheet-like members at the central part, and can realize a new opening and closing structure different from the conventional two-fold structure or bellows structure.

Embodiment

[0008] Hereinafter, an embodiment of the portable storage tool according to the present invention will be described. In this embodiment, a sheet-like member made of natural leather is used as the exterior member, and a plurality of leather parts are used as the internal storage members. First, a plurality of leather parts are arranged in a stacked state, and sewing is performed along their center lines to integrate each leather part. The sewing part along this center line functions as a rotation axis that connects each leather part and allows each leather part to be relatively rotatable around the sewing part. Thereby, the plurality of leather parts have a structure that can be sequentially rotated like the pages of a booklet, and an internal structure in the form of a booklet is formed as a whole. Each leather part can be provided with a storage part such as a card storage part, a banknote storage part, or a free pocket according to the storage target. For example, a card storage section can be formed by sewing a separate leather piece to a part of the leather parts, and a pocket section can be formed by folding back and sewing the leather parts themselves. Next, an exterior member is disposed outside the booklet-shaped internal storage member. The exterior member is provided so as to cover the internal storage member from the outside and is configured to present a booklet-like appearance as a whole when the storage device is closed. Also, closing means can be provided on the exterior member as needed. For example, by using a hook, a button, a belt, a magnet, or the like, a structure can be adopted to hold the storage device in a closed state. According to this embodiment, each storage section can be sequentially unfolded by an operation of turning pages by means of the booklet-like structure formed by sewing a plurality of leather parts at the central portion. Thereby, a portable storage device having a new opening / closing structure and usability different from conventional folding wallets or accordion-structured storage devices can be realized.
