Abstract
Description
Technical Field
[0001] This utility model relates to a portable bag that is formed by overlapping and connecting two oppositely arranged pieces of fabric through sewing or the like, transforming a flat, folded portable bag into a three-dimensional structure so that it can be used quickly. Background Technology
[0002] Japan has a long history of using cloth to wrap items, and in recent years, the concept of the fumoku (wrapping cloth) as a means of transporting items, similar to a bag, has been re-examined. Because the fumoku can be freely deformed, it possesses the following basic characteristics of a bag: the corners of the fumoku can be connected to wrap various shapes and sizes of items, and at the same time, knots can be easily formed to serve as handles for carrying.
[0003] In addition to this basic feature, there are also the following solutions: a fuso-style bag with a rigid body installed at the opening for easy retrieval and placement of items to prevent them from falling out; a tote bag with handles attached to the fuso; and a fuso-style bag with handles that also function as a shoulder bag. These bags are formed by effectively utilizing the fuso, and can be compactly folded and carried as a piece of cloth when not in use.

[0009] Problems to be solved by utility models
[0010] However, all three patent documents have the following problems: when using them, it is necessary to install handle components or adjust the shape of the opening for taking out and putting in the stored items, making the operation complicated.
[0011] In order to solve the above-mentioned problems, the present invention aims to provide a portable bag that can be quickly transformed into a three-dimensional structure without the need for additional handles or auxiliary parts.
[0012] Solution for solving the problem
[0013] The utility model is characterized by comprising: a first fabric and a second fabric arranged opposite to each other; a pair of openings provided on the first fabric; and a bridge formed between the pair of openings, wherein the first fabric and the second fabric are connected to each other at their respective outer peripheries.
[0014] This portable bag is designed to transform from a flat fabric structure into a three-dimensional structure simply by lifting the bridge section and utilizing the bag's own weight. The bridge section and the opening serve as the handle and the entrance / exit for storing items, respectively, making it easy to operate.
[0015] The characteristic feature is that the pair of openings are formed in a line-symmetrical manner.
[0016] When using the portable bag, it is easy and balanced to take out and put in the contents through the opening.
[0017] The characteristic feature is that the axis of symmetry of the opening is not consistent with the center of gravity of the first fabric.
[0018] It can provide portable bags with an overall asymmetrical design and high level of sophistication.
[0019] The portable bag is characterized in that, by lifting the bridge section, it can change from a planar structure to a three-dimensional structure.
[0020] Before lifting the bridge section, the first and second fabric pieces are flatly stacked, forming a planar structure as a whole bag. However, by lifting the bridge section, the first and second fabric pieces form a bag-like storage section, transforming it into a three-dimensional structure. Here, "planar structure" does not mean a completely two-dimensional plane, but rather includes a structure close to the plane formed by stacking two pieces of fabric. "Three-dimensional structure" means that a three-dimensional shape is created from the state of the stacked two pieces of fabric by forming a gap between them.
[0021] Effects of the utility model
[0022] The portable bag according to this utility model has the following advantages: it can provide a portable bag that can be freely deformed like a bundle to store items of various shapes and sizes, and like a Western-style bag, it uses various fabrics, is highly designed and decorative, and combines the characteristics of both.
[0023] Furthermore, by simply lifting the handle of a bag that is a flat structure made by overlapping two pieces of fabric and connecting them with sewing, it can be transformed into a portable bag with a three-dimensional structure. Items can be quickly taken out and put in from the opening, making it less cumbersome to use than traditional fusuke-style bags. Attached Figure Description

[0027] Explanation of reference numerals in the attached figures
[0028] 1. Portable bag; 10. First fabric; 11. Outer perimeter; 20. Second fabric; 21. Outer perimeter; 30. Opening; 31. Inner side; 32. Outer side; 33. Bridge; L. Axis of symmetry; G. Center of gravity. Detailed Implementation
[0029] Reference Figures 1-3 The portable bag 1 includes a first fabric 10 and a second fabric 20 arranged opposite to each other, and a pair of openings 30, 30 provided on the first fabric. No opening is provided on the second fabric 20. In this embodiment, the first fabric 10 and the second fabric 20 are of the same shape and size, more specifically, circular. These first fabrics 10 and second fabrics 20 are stacked, and the outer periphery 11 of the first fabric 10 and the outer periphery 21 of the second fabric 20 are connected to each other. In this embodiment, the connection is made by sewing, but it can also be made by adhesive or the like.
[0030] The openings 30, 30 are formed in a linearly symmetrical manner across the axis of symmetry L. Each opening 30 has an inner portion 31 located on one side of the axis of symmetry L and an outer portion 32 located on the opposite side, forming an annular opening. The inner portion 31 is generally straight, while the outer portion 32 is a curved section bulging outwards. A bridge portion 33, serving as a handle, is formed between the inner portion 31 of one opening 30 and the inner portion 31 of the other opening 30.
[0031] The axis of symmetry L can be different from the center of gravity G of the first fabric 10 and the second fabric 20. In this embodiment, the centers of the first fabric 10 and the second fabric 20 are not aligned with the axis of symmetry L. By making the axis of symmetry L different from the center of gravity G, the design flexibility of the bag during use can be improved. That is, when the bridge 33 is lifted to form a bag shape, a portion of the outer periphery 11 of the first fabric 10 and a portion of the outer periphery 21 of the second fabric 20 are located above, and the opposite portions are located below, implementing an asymmetrical design for the bag as a whole.
[0032] The portable bag 1 described above, when not in use, consists of only the first fabric 10 and the second fabric 20 overlapping, making it easy to fold and compactly carry. In use, items can be inserted through the openings 30, 30, allowing for quick and easy use as a bag without cumbersome steps. These openings 30, 30 are preferably sized for easy insertion and removal of items. The bridge 33 can be used as a handle by lifting it. Therefore, the longitudinal dimension of the bridge 33 is preferably a shape and size that facilitates easy handholding or shoulder carrying.
[0033] The first fabric 10 and the second fabric 20 can be made of durable fabrics such as denim, nylon, and canvas, as well as thinner fabrics. Natural leather and synthetic leather can also be used. Furthermore, the first fabric 10 and the second fabric 20 do not need to be made of the same fabric; they can be made of different fabrics, or different fabrics can be used for specific sections. In particular, by using a more durable fabric for the bridge section 33 than for other parts, a more durable and aesthetically pleasing portable bag 1 can be provided.
[0034] The first fabric 10 and the second fabric 20 may also be lined with additional fabric, making them fully lined. Furthermore, in this embodiment, the first fabric 10 and the second fabric 20 are circular, but this is not a limitation; for example, they could be elliptical or polygonal. Also, while the first fabric 10 and the second fabric 20 are made to have the same shape and size, this is not a limitation. Their size and shape can differ as long as they are connected by the outer perimeter 11 and the outer perimeter 21.
[0035] The openings 30, 30 are designed to be linearly symmetrical, but not necessarily completely linearly symmetrical. They can also be designed to be of different sizes and shapes to the extent that the bridge portion 33 formed by these openings 30, 30 can be designed as a handle.
[0036] The portable bag 1 can also have an additional pocket between the first fabric 10 and the second fabric 20. A zipper can also be installed at the entrance of the pocket. In addition, in order to prevent stored items from falling out of the openings 30, 30 when the bridge 33 is lifted, snaps or the like can be installed on the inside of the outer sides 32, 32 of the openings 30, 30, so that these outer sides 32, 32 can be connected to each other.
[0037] The portable bag described above has the following advantages: it can provide a portable bag that can be freely deformed like a bundle to hold items of various shapes and sizes, and like a Western-style bag, it uses various fabrics, is highly designed and decorative, and combines the characteristics of both.
[0038] Furthermore, by simply lifting the handle of a bag that is a flat structure made by overlapping two pieces of fabric and connecting them with sewing, it can be transformed into a portable bag with a three-dimensional structure. The opening can be used as an entrance for taking out and putting in the contents, allowing for quick access to and from the contents. Therefore, it can be used without the hassle of traditional fusuke-style bags.
