Description

3 IN 1 foldback

The present invention relates to a 3-in-1 foldback that can be used while selectively changing its shape to suit the purpose of use and stored goods, since the shape and storage space can be adjusted by the folding operation of the bag.

A typical bag has an opening on one side of which is opened and an accommodation space capable of accommodating objects therein through the opening.

Since the original purpose of such a bag is to store things, various developments are being made to change the configuration or improve the external aesthetics in order to conveniently store things. For example, it has been developed to divide a storage space to fit the size of an object or to allow a user to carry or wear it conveniently.

However, such a conventional bag has a problem in that it is not useful because it does not provide other functions to improve the convenience of storage or carrying, which is the original purpose of the bag.

Therefore, the present invention has been devised to solve the above-mentioned problems of the prior art, and is configured so that the shape and storage space can be adjusted by the folding operation of the bag, so that the shape can be selectively changed to suit the purpose of use and stored goods. The goal is to provide a possible 3 in 1 foldback.

As a means for solving the above problems, the 3 in 1 foldback of the present invention includes a main body having a square shape on a plane, a first storage space provided therein, and an opening communicating with the first storage space at the top; a pair of first coupling members respectively coupled to both ends of the body along the longitudinal direction; It is characterized by including; and one or more binding rings respectively coupled to the upper and lower portions of the main body.

As an example, the main body is folded based on a transverse center line on a plane so that a pair of first coupling members overlap each other while forming a second storage space having a relatively smaller space than the first storage space, , The pair of first coupling members are characterized in that both ends of the open second storage space are sealed by fastening mutually between overlapping portions.

As an example, one surface of the main body has a virtual divided surface divided into four equal widths along the transverse direction on a plane, and the two divided surfaces in contact with the longitudinal center line are laminated with second coupling members coupled to both ends, respectively. It is characterized by the attachment of members.

As an example, both of the dividing surfaces located on the outside of the dividing surfaces of the main body are folded in a direction in which the stacking member is exposed along the boundary line with the second coupling member, so that the pair of first coupling members overlap each other. In a state where the first coupling members are overlapped, the first coupling member is folded once more in the direction in which the first coupling member is exposed based on the center line in the horizontal direction on the plane, so that each second coupling member overlaps, and the stack facing each other is folded While a third storage space having a relatively smaller space than the first storage space is formed between the members, an auxiliary storage space is formed along the first coupling member to the outside, and each second coupling member provides a space between the overlapping parts. It is characterized in that both ends of the third storage space opened by mutual fastening are sealed, and each first coupling member opens and closes the open auxiliary storage space by selectively fastening between overlapping parts.

As an example, the upper part of the piling member and the main body are selectively coupled or separated by a third coupling member so that the fourth storage space formed between the piling member and the main body is opened or closed, and the fourth storage space It is characterized in that an inner pocket having a relatively shorter length than the third storage space is attached while having a width corresponding to the width of the stacking member.

As an example, the first coupling member, the second coupling member, and the third coupling member are characterized in that they are zippers.

As an example, the inner pocket is characterized in that it is drawn out from the inside of the fourth storage space and covers a selected surface of the main body in an overlapping state.

As an example, a plurality of pen holders are attached to the inner pocket, and one end is connected through a rope to the selected surface of the main body, and a fixing pin for fixing the inner pocket by being inserted into the selected pen holder of the drawn-out inner pocket is mounted. characteristic.

As one example, the main body is characterized in that it further comprises a cover member for covering the exposed first coupling member and the second coupling member coupled along the longitudinal direction of the first coupling member and the second coupling member.

As such, the 3 in 1 foldback of the present invention is configured so that the shape and storage space can be adjusted with a simple folding operation of the bag, so that it can be used while selectively changing its shape to suit the purpose of use and stored goods through one bag Because of this, it has excellent usability and convenience.

In addition, the present invention can be used in parallel as a cover means that can protect the bag by selectively withdrawing the inner pocket provided inside for storage purposes, and there is an excellent effect in terms of design through the use of this cover means.

In describing the present invention, the terms or words used in this specification and claims are based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her invention. should be interpreted as a meaning and concept that corresponds to the technical idea of

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

The 3 in 1 foldback (1) of the present invention is used in three forms having different storage spaces through the fastening of the

coupling members

20 and 40 that overlap each other according to the folding method of the main body 10 and the folding method this is possible

First, referring to FIG. 1, the 3 in 1 foldback 1 of the present invention includes a main body 10 having a square shape on a plane and a pair of first coupling members 20 respectively coupled to both ends of the main body 10 ) And one or more binding rings 30 coupled to the upper and lower portions of the main body 10, respectively.

The main body 10 has a first storage space 100 provided therein and an opening 110 communicating with the first storage space 100 at the top thereof, and through the opening 110, the first storage space 100 You can insert or remove storage items.

1 shows the basic shape of the body 10. In this case, the basic shape is a shape in which the body 10 has the largest area and can be used as a shoulder bag capable of storing relatively large items.

In the present invention, the material of the main body 10 is not limited. However, considering that the shape of the main body 10 is changed by performing a folding operation described below, it is preferable to use a soft material rather than a hard material.

The first coupling members 20 form a pair and are respectively coupled to both ends of the main body 10 along the longitudinal direction.

The first coupling member 20 may face each other and overlap each other as the main body 10 is folded in the transverse or longitudinal direction, and by mutually fastening the overlapped parts, exposed in a bag changed in a different shape Allows the opening to be sealed.

Here, the first coupling member 20 may be applied by selecting a suitable one from a variety of well-known coupling means for coupling between lines, but it is preferable to apply a zipper. In addition, it is more preferable that the shape of the bag is maintained by securing a supporting force by applying a zipper made of metal rather than synthetic resin in the material of the first coupling member 20 .

One or more of the binding rings 30 are coupled to the upper and lower portions of the main body 10, respectively.

The binding ring 30 allows a bag strap, strap, or bag handle suitable for each shape of the main body 10 to be fastened, and may have a ring shape.

In addition, the binding rings 30 are formed at symmetrical positions on the upper and lower portions of the main body 10, so that even when the main body 10 is folded, a bag strap, strap, or bag handle can be fastened at the same position. make it possible

As shown in FIGS. 2A and 2B, the 3 in 1 foldback 1 of the present invention is smaller in size than the original first form (basic form) because the main body 10 is folded based on the horizontal center line on the plane. It is possible to have a true second form.

That is, the main body 10 is folded based on the center line in the transverse direction on a plane, so that the pair of first coupling members 20 overlap each other to form a second shape, and the existing first storage space 100 In the case of , a second storage space having a relatively smaller space than the first storage space 100 is additionally formed between the first storage spaces 100 while being symmetrically divided along the horizontal center line.

At this time, of course, the first storage space 100 in which the opening 110 is not formed among the two divided first storage spaces 100 cannot be utilized.

In addition, the pair of first coupling members 20 overlapped according to the folding operation as described above are fastened to each other between the overlapping parts, so that both ends of the second storage space exposed from both sides of the main body 10 can be sealed. do.

Since the main body 10 of the second form has a form in which the main body 10 of the first form is folded in half, the depth of the first storage space 100 is also reduced by half, such as a laptop computer or a tablet device. It can be used as a pouch to store

On the other hand, according to another embodiment of the present invention, as shown in FIG. 1, one surface of the main body 10 is a virtual divided surface divided into four equal widths (L1, L2, L3, L3) along the transverse direction on the plane , and the stacking member 11 coupled to the second coupling member 40 is attached to both ends of the two dividing surfaces contacting the longitudinal center line.

The second coupling member 40 of the stacking member 11 is a coupling means for changing the body 10 to a third shape smaller than the second shape of the previous embodiment, and each first coupling member 20 on a plane ) and are arranged parallel to each other.

When the main body 10 is changed to the second shape, the second coupling member 40 is folded in a direction in which the second coupling member 40 is exposed from the outer surface of the bag, so that it can also be used as a design element of the bag. allow it to work

Here, the second coupling member 40 may also be a zipper made of metal, similar to the first coupling member 20 .

Hereinafter, a folding method for transforming the main body 10 into a third shape will be described.

First, as shown in FIG. 3A, both of the split surfaces located on the outer side of the split surfaces of the main body 10 are folded along the boundary line with the second coupling member 40 in the direction in which the stacking member 11 is exposed, respectively. The pair of first coupling members 20 face each other and overlap each other.

At this time, the main body 10 is divided into 4 parts with the same width, and both of the dividing surfaces located on the outer side of the dividing surface of the main body 10, that is, both ends of the main body 10 are respectively the boundary line of the second coupling member 40. Since it is folded based on , the overlapping portion between the first coupling members 20 is consequently located on the center line of the rear surface of the main body 10 in the longitudinal direction.

When the first folding operation is completed and the overlapping state between the first coupling members 20 is completed, as shown in FIG. It is folded once more in the direction exposed to the side so that each second coupling member 40 overlaps.

Accordingly, a third storage space 120 having a relatively smaller space than the first storage space 100 is formed between the folded members 11 facing each other.

In addition, when such a second folding operation is performed, as described in the previous embodiment, the first storage space 100 in which the opening 110 is not formed is not available, but in this embodiment, the first storage space 100 that is not available Since the storage space 100 can be exposed by the first coupling member 20, an auxiliary storage space 130 is additionally provided along the first coupling member 20 to the outside of the bag changed to the third shape. can be formed

In addition, each second coupling member 40 is capable of sealing both ends of the open third storage space 120 by mutually fastening the overlapping portions, and each first coupling member 20 connects between the overlapping portions. It is possible to open and close the auxiliary storage space 130 opened by selectively fastening.

Since the main body 10 deformed into the third shape through the two fold operations has the smallest size, it can be used as a cross bag that can accommodate and carry small cell phones or wallets.

On the other hand, according to an embodiment of the present invention, as shown in FIG. 1, the top of the stacking member 11 and one side of the main body 10 are selectively combined or separated by a third coupling member 50 to be laminated. The fourth storage space 140 formed between the member 11 and one surface of the main body 10 can be opened or closed.

At this time, the third coupling member 50 may also be a metal zipper similar to the first coupling member 20 and the second coupling member 40 .

And, in the case of the fourth storage space 140, the space itself can be used as a storage space, but in the bag of the third type, it is preferable to have an internal pocket 60 so that it can be used concurrently as a cover means.

Specifically, the inner pocket 60 is attached to the inside of the fourth storage space 140, has a width corresponding to the width of the stacking member 11, and is relatively larger than the third storage space 120. It is configured to have a short length.

As shown in FIG. 4A, the inner pocket 60 is pulled out from the inside of the fourth storage space 140 and the main body 10 is overlapped, that is, the bag is deformed into the third shape. ), it protects the entrance of the third storage space 120 opened from the upper part of the bag from being exposed and also serves as a design element of the bag.

In addition, a plurality of pen holders 61 are attached to the inner pocket 60 so that writing instruments such as pens can be stored when the inner pocket 60 is stored in the fourth storage space 140.

And on one side of the body 10, one end is connected through a rope 70 and inserted into the selected pen holder 61 of the drawn-out inner pocket 60 to fix the inner pocket 60. A fixing pin 71 is mounted has been

That is, as shown in FIG. 4B, the fixing pin 71 is attached to any one pen stand 61 attached to the exposed surface of the inner pocket 60 in a state where the inner pocket 60 is drawn out and covers one surface of the main body 10 ) is inserted and fastened so that the movement of the inner pocket 60 used as a cover means is fixed.

At this time, the fixing pin 71 forms a protrusion slightly larger than the diameter of the pen holder 61 along its outer circumferential surface to prevent the fixing pin 71 inserted into the pen holder 61 from easily falling out during the user's movement. It is desirable to allow the pocket 60 to be more firmly fixed.

On the other hand, as shown in FIG. 5, the body 10 is coupled along the longitudinal direction of the first coupling member 20 and the second coupling member 40, and the exposed first coupling member 20 and the second coupling A cover member 80 covering the member 40 may be further included.

This cover member 80 is different due to friction or collision with the first coupling member 20 or the second coupling member 40 exposed in the zipper structure in both the first shape as well as the second and third shapes of the bag. It is possible to prevent damage to articles or user's clothing.

In addition, although not shown in the drawings, a ring that can be raised on the handle of the travel trunk bag and a detachable strap that can be detached from the user's waist are additionally mounted on the rear side of the 3 in 1 foldback (1) of the present invention, so that it can be used as needed. The bag can be placed in various ways.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concept of the present invention defined in the following claims are also made according to the present invention. falls within the scope of the rights of
