Description

[Technical Field]

[0001] The present invention relates to a multi-mode bag, specifically to a designer bag that combines design and functionality, allowing the bag's use to be easily changed even when out and about. [Background technology]

[0002] Bags are fashion items used in everyday life. Bags are required to have both design and functionality, and there are various types, such as crossbody bags worn diagonally across the body, shoulder bags worn over the shoulder, and handbags worn on the arm. Because bags reflect the owner's preferences, there is a demand for bags that can be used in different ways, for example, from a handbag to a shoulder bag, while retaining the design of the bag itself. Patent Document 1 discloses a bag that can be transformed into multiple shapes and used for various purposes. The bag has attachment parts at two locations on the bag body, and locking parts at both ends of the shoulder straps. When the length of the shoulder straps is adjusted to be shorter, the excess length of the shoulder straps is inserted and held within the shoulder strap guide parts of the bag body, allowing the bag to be transformed into multiple shapes and used for various purposes. Also known are bags that come with straps of different lengths to accommodate various sizes, such as crossbody, shoulder, and hand-carrying, and can be attached to different straps depending on the purpose. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3158582 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional technology has the following problems. <1> When the bag of Patent Document 1 is used as a handbag, the shoulder straps are exposed to the outside of the bag body and the surface of the bag body is pulled by the shoulder straps, significantly compromising the design. In particular, when the bag is placed on a desk or other surface, the loose shoulder straps bulge outward, further compromising the appearance. Furthermore, it is time-consuming to insert the shoulder straps into the shoulder strap guides on the bottom, making the bag less convenient. <2> Bags that use multiple straps of different lengths require the storage of multiple straps, which makes management cumbersome, and if a strap is lost, it becomes impossible to change the bag's use.Furthermore, if you do not have the strap with you, you cannot change the bag's use while you are out. <3> Both bags have a fixed strap position, so it is not possible to fine-tune the hanging position of the bag to suit one's body shape or fashion.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a multi-mode bag that can solve the above problems. [Means for solving the problem]

[0006] The multi-mode bag of the present invention comprises a bag body and a belt, the bag body comprising two body sections constituting the front and rear surfaces of the bag body, a gusset section constituting both side surfaces and the bottom surface of the bag body and connecting the two body sections, a sheath section covering the gusset section continuously from the middle of the first side surface through the bottom surface to the middle of the second side surface, an insertion passage communicating between the gusset section and the sheath section along the longitudinal direction of the sheath section, and a connecting means fixed to the second side surface above the sheath section. , wherein the belt comprises a fixed end portion fixed to a position above the sheath portion on the first side surface, and a belt portion extending upward from the fixed end portion, which has a shape that can be inserted into the insertion passage, and which can be connected to the connecting means at any position in the longitudinal direction, and the sheath portion has a fixed side on one side in the width direction that is fixed to the gusset portion, and an expansion side on the other side in the width direction that is detachable from the gusset portion, and the expansion side is configured to be expandable in the width direction relative to the gusset portion.

[0007] In the multimode bag of the present invention, the deployed side may be magnetically attached to the gusset portion.

[0008] In the multimode bag of the present invention, the sheath portion may be composed of a plurality of divided bodies arranged in parallel in the longitudinal direction.

[0009] In the multimode bag of the present invention, the gusset portion and the sheath portion may have a gently curved shape at the connection portion between the side surface and the bottom surface. [Effects of the Invention]

[0010] The multi-mode bag of the present invention has at least one of the following advantages. <1> The excess length of the belt can be stored compactly along the outer periphery of the bag body, which means that there is no visible sign of the belt length being adjusted, and it looks as if the belt is at a preset length, maintaining a high level of design. <2> Even if the belt has a long excess length, the belt can be easily stored in the insertion passage by expanding the sheath portion in the width direction. <3> There is no need to change the strap, so you can easily change the use of the bag while you are out. <4> The belt can be connected to the bag body at any length, allowing you to fine-tune the hanging position of the bag to suit your body shape and fashion. [Brief explanation of the drawings]

[0011] [Figure 1] Multi-mode bag illustration [Figure 2] Diagram of the bag body [Figure 3] Sheath diagram [Figure 4] Diagram of the passage [Figure 5] Illustration of the shape of the multi-mode bag DETAILED DESCRIPTION OF THE INVENTION

[0012] The multi-mode bag of the present invention will be described in detail below with reference to the drawings. [Example]

[0013] [Multi-mode bag] <1> Overall configuration (Figure 1) The multi-mode bag 1 is a bag that can be changed into multiple forms, such as a handbag, a shoulder bag, and a crossbody bag, without the need to replace any components. The multi-mode bag 1 includes at least a bag body 10 and a belt 20. In this example, the multi-mode bag 1 is made of leather except for the metal fittings. However, the material is not limited to this, and may be artificial leather, canvas, or the like.

[0014] <2> Bag body (Figure 2) The bag body 10 is a component for storing items. The bag body 10 includes at least two body portions 11, a gusset portion 12, a sheath portion 14, an insertion passage 15, and a connecting means 16. The body portion 11 constitutes the front and rear surfaces of the bag body 10. The gusset portion 12 constitutes both sides and the bottom of the bag body 10, and connects the front and rear body portions 11. In this example, the body portion 11 and the gusset portion 12 are separate members, but this is not limiting. For example, the body portion 11 may be a single piece, or the body portion 10 and the gusset portion 12 may be integrated as in a drawstring bag. An opening 13 that connects to the inside of the bag body 10 is defined at the top of the bag body 10 between the body portion 11 and the gusset portion 12, and in this example, the top of the opening 13 is covered by a lid portion 17 that can be opened and closed freely. The sheath portion 14 covers the lower sides and bottom surface of the gusset portion 12 . The insertion passage 15 communicates between the gusset portion 12 and the sheath portion 14 . The connecting means 16 is attached to the second side surface 12 b of the gusset portion 12 above the sheath portion 14 . In this example, the gusset portion 12 and the sheath portion 14 have a gently curved shape at the connection between the side and bottom surfaces. This allows the belt 20 to slide smoothly inside the insertion passage 15, making insertion easier, and because the sheath portion 14 has no corners, it is easier to unfold the sheath portion 14 laterally, as will be described later.

[0015] <2.1> Sheath part (Fig. 3) The sheath portion 14 is a member that partially covers the gusset portion 12 to define the insertion passage 15. In detail, the sheath portion 14 continuously covers the gusset portion 12 from the middle of the first side surface 12a, through the bottom surface 12c, to the middle of the second side surface 12b. In this example, the sheath portion 14 is configured from two divided pieces arranged in parallel in the longitudinal direction, but is not limited to this and may be configured from one piece or three or more divided pieces. The sheath portion 14 has a fixed side 14a fixed to the gusset portion 12 on one side in the width direction, and an expanded side 14b detachably attached to the gusset portion 12 on the other side in the width direction. This structure allows the sheath portion 14 to be unfolded in the width direction (toward the unfolding side 14b) relative to the gusset portion 12. When the sheath portion 14 is a divided body as in this example, it is easier to unfold than when it is a single piece. In this example, magnets and metal pieces are placed inside the gusset portion 12 and on the inner surface of the unfolded side 14b, and the unfolded side 14b is magnetically attached to the gusset portion 12. Alternatively, a structure in which a detachable member such as a hook-and-loop fastener is attached to the gusset portion 12 and the unfolded side 14b, or a structure in which the shape elasticity of the material of the sheath portion 14 is utilized may be used.

[0016] <2.2> Insertion passage (Fig. 4) The insertion passage 15 is a space capable of accommodating the belt 20 therein. The insertion passage 15 extends along the longitudinal direction of the sheath portion 14 between the surface of the gusset portion 12 and the inner surface of the sheath portion 14. In detail, by linearly fixing both widthwise end edges of the sheath portion 14 to both widthwise end edges of the gusset portion 12, the insertion passage 15 is formed as a space that is approximately U-shaped in a front view along the outer periphery of the gusset portion 12. For ease of explanation, FIG. 4 shows the sheath portion 14 in a cross section cut in the width direction.

[0017] <2.3> Connection means The connecting means 16 is a means for connecting to the belt 20 at an arbitrary position. The connecting means 16 is fixed to the second side surface 12b of the gusset portion 12 above the sheath portion 14. In this example, a trench buckle sewn to the second side surface 12b is used as the connecting means 16. In detail, a fixing piece wound around the center axis of the trench buckle is sewn to the second side surface 12b and fixed, and the belt portion 22 is connected to the belt 20 at any position in the longitudinal direction of the belt portion 22 by communicating with the two gaps of the trench buckle. However, the connecting means 16 is not limited to a trench buckle, and may be, for example, a ring buckle, a tube buckle, a roller buckle, or the like, as long as it has a structure that allows it to be connected to the belt 20 at any position.

[0018] <3> belt The belt 20 is a component that suspends the bag body 10. The belt 20 includes at least a fixed end portion 21 fixed to the bag body 10 and a long belt portion 22 extending upward from the fixed end portion 21 . The fixed end portion 21 is fixed to the first side surface 12a of the gusset portion 12 above the sheath portion 14. The belt portion 22 has a shape that allows it to be inserted into the insertion passage 15. Specifically, the height of the belt portion 22 is smaller than the height of the insertion passage 15, and the width of the belt portion 22 is smaller than the width of the insertion passage 15. Preferably, the width of the belt portion 22 is about half the width of the insertion passage 15. The length of the belt portion 22 is preferably set to the length of a crossbody bag, for example, about 130 cm. If belt 20 is made slim and made of soft natural leather to enhance the design, tip 22a may bend as it is pushed in, making it difficult to push tip 22a into insertion passage 15. In such a case, belt 22 can be easily stored in insertion passage 15 from the width direction by opening expansion side 14b of sheath portion 14.

[0019] <4> Multimode bag configuration (Figure 5) The multi-mode bag 1 can be transformed into a number of different shapes depending on the connection position of the connecting means 16 and the belt portion 22. The middle 22b of the belt portion 22 is connected to the connecting means 16 at a position about 30 to 40 cm from the fixed end 21 side, and the tip 22a is connected from the second side surface 12b side to the inside of the insertion passage 15, thereby forming a handbag (FIG. 5(a)). If the tip 22a side of the belt portion 22 is too long, the tip 22a will protrude from the inside of the insertion passage 15 towards the first side surface 12a. In this case, a belt hole may be provided near the tip 22a of the belt portion 22, and the belt may be fastened by a protrusion provided on the first side surface 12a. The middle 22b of the belt portion 22 is connected to the connecting means 16 at a position approximately 80 to 90 cm from the fixed end 21 side, and the tip 22a is connected to the insertion passage 15 from the second side 12b side, thereby forming a shoulder bag (Figure 5(b)). The vicinity of the tip 22a of the belt part 22 is connected to the connecting means 16, and the tip 22a is communicated from the second side surface 12b side into the insertion passage 15, thereby forming a crossbody bag (FIG. 5(c)). Note that if the tip 22a does not extend beyond the connecting means 16, the tip 22a may not be inserted into the insertion passage 15.

[0020] <5> Sheath Function The multi-mode bag 1 of the present invention has an insertion passage 15 formed by the sheath portion 14 along the outer periphery of the gusset portion 12, allowing the tip of the belt portion 22 to be inserted and stored compactly along the outer periphery of the gusset portion 12. This allows the appearance to be free of any visible signs that the length of the belt 20 has been adjusted, maintaining a high level of design quality. Furthermore, when the multi-mode bag 1 is used as a handbag, the length of the belt portion 22 to be inserted into the insertion passage 15 becomes considerably long, and it is a time-consuming and difficult task to insert the tip 22a into the insertion passage 15 while passing the middle 22b of the belt portion 22 through the connecting means 16. Therefore, in this case, the middle portion 22b of the belt portion 22 is first connected to the connecting means 16 at a predetermined position without inserting the tip portion 22a into the insertion passage 15. Next, the sheath portion 14 is unfolded in the width direction, and the remaining belt portion 22 is positioned on the gusset portion 12 from the width direction and the unfolded side 14b is closed, so that the belt portion 22 can be easily stored in the insertion passage 15.
