Variable capacity bag

Abstract

To provide a bag having an expansion function for increasing the capacity of a storage section of a bag body as required while maintaining convenience as a body bag in a compact size under normal circumstances. [Solution] An expansion member 11 is provided in the bag body 2, and an expansion zipper F3 is provided to store it. When the zipper is closed, the expansion member is stored, resulting in a compact size, and when it is opened, the expansion member is exposed, increasing the storage capacity of the bag body. A thin front member 3 that is wider in both vertical and horizontal dimensions than the bag body is sewn to the front of the bag body, and the expansion zipper is attached to the adhesive part between the front member and the bag body, so the expansion zipper is not exposed when viewed from the front.

Description

[Technical Field]

[0001] This case concerns a variable capacity bag, a body bag that can be worn across the body or over the shoulder. [Background technology]

[0002] The primary functionality required of a body bag worn across the body or over the shoulder is its compact size and ease of carrying compared to other types of bags. However, there is a drawback to this type of bag, as it cannot carry a lot of luggage, limiting its use or causing inconvenience.

[0003] Furthermore, the variable-capacity bag using the expansion zipper according to the conventional technology of Patent Document 1 has the drawback that the expansion zipper is exposed to the exterior, which affects the design and reduces the fashionability, thereby reducing the product value as a fashion item. [Prior art documents]

[0004] [Patent Document 1] Utility Model Registration No. 3248944 Summary of the Invention [Problem to be solved by the invention]

[0005] There are many types of bags available in the world, and users can choose a bag with a large capacity to suit their desired storage capacity. Among these, the role and characteristics required of a body bag are that it can be worn across the body or over the shoulder to carry a small amount of luggage. For this reason, conventional body bags are mostly compact in size, but have a small storage capacity.

[0006] As a result, when you have more luggage than usual or when you are out and about, it has the disadvantage of not being able to store all of your belongings, which limits the opportunities and situations in which it can be used.While it has the advantage of being light to carry, it has the issue of low functionality as a bag originally intended for storage.

[0007] Furthermore, bags are fashion items, and design is important. The variable capacity bag using a conventional expansion fastener, as in Patent Document 1, has the problem that the expansion fastener is exposed to the exterior, which reduces design. There is a need to achieve the functionality of variable capacity without affecting design. Means to solve this problem

[0008] This variable-capacity bag is a body bag that has an expansion member in the bag body, which includes the main storage section, and the storage capacity of the bag body can be changed by opening and closing the expansion fastener stored by folding the expansion member.

[0009] When the slider of the expansion fastener installed on the bag body is pulled to the end, it becomes closed and the expansion member is folded, resulting in a compact shape for the bag body.When the slider of the zipper is pulled to the start, it becomes open and the expansion member is exposed, expanding the storage capacity of the bag body.

[0010] In addition, a pocket-shaped front member that is wider in width and height than the bag body is attached to the front of the bag body, and when viewed from the front, the bag body is hidden by the front member. The expansion zipper is installed at the connection point between the bag body and the front member, so the expansion zipper is hidden behind the front member, solving the problem of the loss of design appearance due to the exposure of the expansion zipper in the conventional technology. It can also be used as a waist bag by wearing it around the waist. Effects of the invention

[0011] The above-described structure maintains the lightweight carrying characteristics required of a body bag while eliminating the drawbacks of the small storage capacity of conventional body bags, and by attaching the expansion zipper in a way that does not affect the appearance, it is possible to create a variable-capacity bag that does not detract from its commercial value as a fashion item.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described. 2 and 3, this body bag 1 mainly consists of a bag body 2 including a storage compartment, with a front member 3 sewn to the front of the bag body 2, end fixing members 8 sewn to both ends of the back body 4, and a belt 13 sewn to the tip of the end fixing member 8. Belt 13 passes through an adjuster 10 and then through a buckle 12, and the length of belt 13 can be adjusted by sliding belt 13 through buckle 12, and the bag can function as a body bag worn across the body or over the shoulder, or as a waist bag worn around the waist.

[0014] As shown in Fig. 3, the bag body 2 including the storage compartment has two zippers. The second zipper F2 is an opening for accessing the bag body 2 including the storage compartment, and sliders 6a, 6b and tabs 7a, 7b are provided on the top of the bag body 2. As shown in Fig. 4, the third zipper F3 is for storing the expansion member 11 folded inward, and is provided so as to go around the bag body as shown in Figs. 3 and 6, and when the third zipper F3 is closed, the slider 6c and tab 7c are provided on the bottom of the bag as shown in Fig. 6.

[0015] As shown in Figures 6 and 7, by opening the third zipper F3 from the start end C to the end end O, the expansion member 11 is exposed and the depth of the bag body 2 is expanded, thereby varying the storage capacity of the bag body 2. As a result, when the third zipper F3 is closed, the compact convenience that is a characteristic of body bags is maintained, and when the amount of luggage increases, the capacity can be increased by opening the third zipper F3, improving usability.

[0016] As shown in Figures 2, 3, and 4, a front member 3 is sewn to the front of the bag body 2. As shown in Figures 1 and 4, the front member 3 is a storage compartment that opens and closes with a fourth zipper F4, and has a flat shape with no gusset. The front member 3 is designed to be wider in width and vertical width than the bag body 2, so as shown in Figures 1 and 4, the bag body 2 is hidden by the front member 3 when viewed from the front.

[0017] As shown in Figures 3, 4, and 6, the third zipper F3 is provided along the connection between the bag body 2 and the front member 3, so that when the third zipper F3 is closed, it is hidden by the front member 3 and is not exposed when viewed from the front or diagonally from the front, as shown in Figures 1 and 4. This allows the third zipper F3, which is for expansion, to be used without compromising the design of the bag, maintaining its appeal as a fashionable product and realizing convenience through adjustable capacity. The fourth zipper F4 shown in Figure 2 is an access opening for the back body part 4, which includes the storage compartment.

[0018] 3, loop fixing members 9a and 9b, which are loop-shaped connecting parts, are sewn to both ends of the front member 3, with 9a fixed to adjuster 10a and 9b fixed to adjuster 10b. Also as shown in Fig. 3, an end fixing member 8a to which a belt 13a is sewn is provided at the left end of the back surface 4 of the main body, and an end fixing member 8b to which a belt 13b is sewn is provided at the right end of the back surface 4 of the main body, with belt 13a passed through adjuster 10a and belt 13b passed through adjuster 10b, and each is capable of sliding movement.

[0019] With this mechanism, as shown in Figures 3 and 5, when the capacity of the bag body 2 increases and the depth expands by opening the third zipper F3, the widths A and B can be adjusted by sliding the belts 13a and 13b passed through the adjusters 10a and 10b, making it possible to adjust the size to suit the change in capacity.
