However, with a conventional tote bag, if a handle for carrying a hand is hung on both shoulders like a rucksack, one of the sides of the bag will hit the back of the user, so it is difficult to carry it on the back. It also looks bad. Furthermore, when the depth of the tote bag is relatively small, the center of gravity of the bag is located at the information when used as a rucksack, so it is not stable.

An object of the present invention is to provide a tote bag that is stable, easy to carry on the back, and has a good appearance when used as a rucksack.

One embodiment of the present invention that achieves the above object is a bag having a first state used as a rucksack and a second state used as a tote bag, and a bag portion having an opening at the upper end. A pair of string portions provided on one side and the other side with respect to the opening on the upper end side of the bag portion, and the bag portion has a tubular inner fabric and an upper connecting tool. It has an upper outer fabric connected to the outside of the inner fabric and a lower outer fabric having a lower connecting tool connectable to the upper connecting tool and connected to the outside of the inner fabric, and the first state. At this time, the inner fabric is stretched and exposed between the lower end of the upper outer fabric and the upper end of the lower outer fabric, and from the first state, the inner fabric is abbreviated with the vertical direction as the rotation axis. A 90-degree twist is applied, contracted, and housed inside the upper outer fabric and the lower outer fabric, and the upper connecting tool is connected to the lower connecting tool to achieve the second state.

With this configuration, when used as a rucksack, the inner fabric is twisted approximately 90 degrees so that the flat portion formed on the upper outer fabric having the string portion hits the back of the user, so that it can be used as a rucksack. It is possible to provide a tote bag that is easy to carry on the back and looks good when used. In addition, when used as a rucksack, the bag extends by the length of the inner fabric in the vertical direction, so that the center of gravity is lowered and the bag can be stably carried on the back.

In another embodiment, the inner fabric has a portion that is connected to the upper outer fabric in the vicinity of the opening and is covered by the upper outer fabric and is not exposed, and the unexposed portion and the first state. The twist is applied to the exposed portion.

With this configuration, it is possible to secure a long area in the vertical direction including the part that is covered and not exposed as a twisting area while keeping the part that extends apparently to the exposed part of the inner fabric, so that the appearance is maintained. However, it is possible to add a twist efficiently.

In another embodiment, the upper outer fabric is a position in which the binding portion in which one end and the other end of the fabric are sewn faces the back of the user in the first state, and is the second. It has on one side in the width direction in the state of.

With this configuration, when used as a rucksack, the only binding portion touches the back of the user and is not exposed to the outside, so that it is possible to prevent deterioration of the appearance.

In another embodiment, in the first state, the upper connecting tool and the lower connecting tool are provided at positions displaced by approximately 90 degrees in the circumferential direction of the rotation axis.

With this configuration, a twist can be added by rotating the upper connecting tool and the lower connecting tool relative to each other by 90 degrees in the circumferential direction.

In another embodiment, the string portion is connected to the upper outer fabric at a predetermined distance downward from the opening.

With this configuration, when used as a rucksack, the length as a shoulder strap can be sufficiently secured.

According to the present invention, it is possible to provide a tote bag that is stable, easy to carry on the back, and has a good appearance when used as a rucksack.

Hereinafter, the present invention will be described with reference to the drawings.
In the drawings, the three axes orthogonal to each other are indicated by the symbols X, Y, and Z.

1, FIG. 2 and FIG. 3 are perspective views showing a bag 10 according to an embodiment of the present invention. The bag 10 according to the present embodiment has at least a "first state used as a rucksack" and a "second state used as a tote bag", from a first state to a second state, or. , Transforms from the second state to the first state. FIG. 1 shows the second state, and FIGS. 2 and 3 show the first state. FIG. 3 is a view of the bag 10 as viewed from the side opposite to FIG. 2.

As shown in these figures, the vertical length H2 of the bag 10 in the first state is longer than the vertical length H1 of the bag 10 in the second state.

Hereinafter, the structure of the bag 10 will be described first, and then the method of deforming the bag 10 will be described.

(Bag structure)
As shown in FIGS. 1, 2, and 3, the bag 10 according to the present embodiment has a bag portion 100 and a pair of string portions 200. The bag portion 100 has an opening 105 at the upper end (Z-axis positive direction). The string portion 200 is provided on one side and the other side with respect to the opening 105 of the bag portion 100, and is provided so as to be arranged in the Y-axis direction in FIGS. 1 to 3. The string portion 200 functions as a handle when the bag 10 is used as a tote bag, and as a shoulder strap when used as a rucksack.

The bag portion 100 has a tubular inner fabric 110, an upper outer fabric 120, and a lower outer fabric 130. The inner fabric 110 is housed inside the upper outer fabric 120 and the lower outer fabric 130 in the second state (FIG. 1) used as a tote bag, and is not visible from the outside, and is therefore shown by a broken line. In the first state (FIGS. 2 and 3) in which the inner fabric 110 is used as a rucksack, a part of the inner fabric 110 is exposed but a part of the inner fabric 110 is not visible, so that the invisible portion is shown by a broken line.

The string portion 200 is connected to the upper outer fabric 120 at a predetermined distance D1 downward from the opening 105 and at a position away from the opening 105. This is to ensure the length as a shoulder strap when the bag 10 is used as a rucksack, which will be described later.

The material of the inner fabric 110, the upper outer fabric 120, and the lower outer fabric 130 is a flexible material, and for example, a canvas fabric or a synthetic fiber fabric such as nylon or polyester can be used. In the state of FIG. 1, the inner fabric 110 is housed in a state in which a twist of approximately 90 degrees is applied in the circumferential direction in the vertical (Z-axis) direction.

The upper outer fabric 120 is connected to the outside of the inner fabric 110 by means such as sewing, and further has an upper connecting tool 121 for connecting to the lower outer fabric 130. The upper outer fabric 120 is connected to the inner fabric 110 in the vicinity of the opening 105. That is, the inner fabric 110 is connected to the upper outer fabric 120 only at the upper end in a state where the upper portion is covered with the upper outer fabric 120 in a state where the upper end is shared with the upper outer fabric 120.

Similarly, the lower outer fabric 130 is connected to the outside of the inner fabric 110 by means such as sewing, and further has a lower connecting tool 131 for connecting to the upper outer fabric 120. That is, the inner fabric 110 is connected to the lower outer fabric 130 only at the lower end in a state where the lower portion is covered with the lower outer fabric 130 in a state where the lower end is shared with the lower outer fabric 130.

The upper outer fabric 120 is made of one piece of fabric, and has a binding portion 122 in which one end and the other end of the fabric are sewn. That is, the binding portion 122 is provided only on one side of the bag 10 (the right side surface of FIG. 1, the center of FIG. 3). As shown in FIG. 1, when the bag 10 is used as a tote bag, the binding portion 122 is arranged on one side of the bag 10 in the width direction. When the bag 10 is used as a rucksack, the binding portion 122 is located at the back. (However, in FIG. 2, since it is blocked by the bag portion 100 and cannot be seen, the illustration and the reference numeral are omitted.) In the negative direction of the X axis in FIGS. 2 and 3, the bag 10 is used as a rucksack. In some cases, the direction facing the user's back, and the surface on which the binding portion 122 is arranged is the surface in contact with (opposing) the user's back.

The lower outer fabric 130 also has a binding portion 132 on one side of the bag 10 in the width direction in FIG. In FIG. 1, the binding portion 132 of the lower outer fabric 130 is shown so as to be located in the negative direction in the X-axis direction, but the bag 10 is deformed from the state of being used as a tote bag to the state of being used as a rucksack. At that time, the twist of about 90 degrees applied to the inner fabric 110 is released and stretched, and the lower outer fabric 130 also rotates in the vertical direction and clockwise when viewed from above in conjunction with this. , In FIG. 2, it is illustrated in the negative direction of the Y axis.

As shown in FIG. 2, when the applied twist is released and the inner fabric 110 is stretched, a part of the inner fabric 110 is exposed between the lower end of the upper outer fabric 120 and the upper end of the lower outer fabric 130. Further, as described above, the inner fabric 110 also has a portion covered with the upper outer fabric 120 and not exposed. This unexposed portion is a portion from the vicinity of the opening 105 where the inner fabric 110 and the upper outer fabric 120 are connected to the lower end of the upper outer fabric 120. A twist of approximately 90 degrees is applied to approximately the entire tubular inner fabric 110. Therefore, a twist is applied to both the unexposed portion and the exposed portion.

The lower connecting tool 131 is a connecting tool that can be connected to the upper connecting tool 121. The upper connecting tool 121 and the lower connecting tool 131 in the present embodiment are slide fasteners. However, this is only an example, and may be implemented by, for example, a hook-and-loop fastener or a button (including a hook or a magnet).

The upper connector 121, which is one side of the slide fastener, is arranged inside the lower end of the upper outer fabric 120 along the lower end, and has a slider fitting portion 123 of the slider 250.

Similarly, the lower connector 131, which is the other side of the slide fastener, is arranged along the upper end inside the upper end of the lower outer fabric 130, and the slider fitting portion into which the slider 250 fits at the end. It has 133.

Here, as shown in FIG. 2, when the bag 10 is used as a rucksack, the upper connecting tool 121 and the corresponding lower connecting tool 131 are approximately 90 degrees in the circumferential direction of the Z axis. It is provided at a displaced position. Therefore, the slider fitting portion 123 and the slider fitting portion 133 are also provided at positions displaced by approximately 90 degrees when viewed from above.

(How to deform the bag)
The method of deforming the bag 10 described above will be described below with reference to FIG.

4A and 4B are views showing a method of deforming the bag 10 according to the present embodiment, FIG. 4A is a state of being used as a tote bag, FIG. 4C is a state of being used as a rucksack, and FIG. (B) shows an intermediate state.

Explaining from the method of transforming the tote bag into a rucksack, the user first slides the slide 250 in the state of the figure (A) to connect the upper connecting tool 121 and the lower connecting tool 131 in the connected state. Remove (S1 in the same figure). Subsequently, the inner fabric 110 in the twisted state is stretched downward while being untwisted (S2 in the figure). As a result, the bag 10 is in the state shown in FIG.

Subsequently, as shown in the figure (B), the user pushes both ends of the upper outer fabric 120 of the unfolded bag 10 inward by hand to change the width, depth, and length of the bag 10. Swap the horizontal (front / back) and gusset (side) of (S3 in the figure). By eliminating the twist and replacing the horizontal and gusset in this way, the orientation of the bag 10 changes, and a flat portion of the upper outer fabric 120 is formed on the portion corresponding to the user's back, as shown in FIG. It will be easier to carry on your back. Note that FIG. C shows the bag 10 rotated 90 degrees around the Z axis from the angle shown in FIG.

Next, to explain how to transform the rucksack into a tote bag, the user pushes the upper part of the bag 10 by hand, changes its width and depth, and the length of each, and replaces the width and gusset of the bag 10 (Fig. 4). The reverse of S3 in (B)). Subsequently, the lower part is held and contracted in the Z-axis direction while being twisted approximately 90 degrees, and the inner cloth 110 is stored between the upper outer cloth 120 and the lower outer cloth 130.

Subsequently, the slider 250 attached to the upper connector 121 is fitted to the slider fitting portion 133 of the lower connector 131 and slid to connect the upper connector 121 and the lower connector 131. As a result, the bag 10 can be transformed from the state of being used as a rucksack shown in FIG. 4 (C) to the state of being used as a tote shown in FIG. 4 (A).

(How to use the bag)
Hereinafter, the method of using the bag 10 will be described, and the actions and effects brought about by the above-mentioned structure will be further described.

FIG. 5 is a diagram illustrating three ways of using the bag 10. As shown in FIG. 5A, the user holds the string portion 200 in his / her hand or hangs it on his / her shoulder when the baggage is small or when there is no problem even if one hand is blocked by the bag 10. Can be used as a tote bag. In this case, the entire bag 10 is compact and has the advantage of being easy to carry.

As shown in FIGS. 5 (B) and 5 (C), when the luggage has increased or when both hands are desired to be free (including while exercising or riding a bicycle), the user puts the bag 10 on the bag 10. It transforms into a state where it is used as a rucksack. The state (first state) referred to here as "a state used as a rucksack" for the sake of convenience is not intended to limit the mode of use. As shown in FIG. 5B, the bag 10 in this state may be used as a long tote bag (long tote).

When the bag 10 is used as a rucksack, the user hangs the string portion 200 on the shoulder and uses it as a shoulder strap as shown in FIG. 5 (C).

When the bag 10 according to the present embodiment is used as a rucksack, the inner fabric 110 is twisted approximately 90 degrees from the state in which it is used as a tote bag, so that the horizontal and gusset are interchanged. The portion (the surface provided on each side of the pair of string portions 200) comes into contact with the back of the user. Therefore, the bag 10 is easy to carry when used as a rucksack. Also, when used as a rucksack, the height H2 of the bag 10 is extended to a height above the waist for an average height user, for example, as shown in FIG. Therefore, the center of gravity of the entire bag 10 is lower and easier to carry because the bag 10 is extended by the length of the inner fabric 110 in the vertical direction, as compared with the case where the bag 10 is carried on the back as it is used as a tote bag. In addition, it looks and looks better than carrying it on its back as it is used as a tote bag, and its fashionability is further improved.

Further, the bag 10 according to the present embodiment does not have a configuration in which a twist is applied only to the exposed portion of the inner fabric 110 as shown in FIGS. 5 (B) and 5 (C), and the inner fabric 110 has an upper portion from the vicinity of the opening 105. It has a portion covered by the outer fabric 120 and not exposed. Both the unexposed and exposed parts are used as twisted areas.

With this configuration, it is possible to secure a long area in the vertical direction including a portion covered and not exposed as a twisting region while the portion where the bag 10 extends is apparently limited to the exposed portion of the inner fabric 110. According to the structure of the bag 10, it is possible to efficiently add a twist while maintaining the appearance. A design element may be added to the exposed portion. In this case, when the design element is used as a tote bag, it is hidden, and when it is used as a rucksack, it can be configured to be visible from the outside for the first time, and fashionability can be improved.

Further, the bag 10 according to the present embodiment has the only binding portion 122 of the upper outer fabric 120 at a position facing the back of the user when used as a rucksack.

With this configuration, when used as a rucksack, the only binding portion 122 hits the back of the user and is not exposed to the outside, so that it is possible to prevent deterioration of the appearance.

Further, when the bag 10 according to the present embodiment is used as a rucksack, the upper connecting tool 121 and the lower connecting tool 131 are displaced by approximately 90 degrees in the circumferential direction of the Z axis, which is the rotation axis of the twist. It is provided in. With this configuration, the bag 10 can be twisted by rotating the upper connector 121 and the lower connector 131 relative to each other by 90 degrees in the circumferential direction.

Further, in the bag 10 according to the present embodiment, the string portion 200 is connected to the upper outer fabric 120 at a predetermined distance D1 downward from the opening 105 and at a position away from the opening 105. With this configuration, when the bag 10 is used as a rucksack, the length as a shoulder strap can be sufficiently secured.

This embodiment can be modified in various ways. In the present embodiment, the upper connecting tool 121 and the lower connecting tool 131 as slide fasteners may be implemented by buttons. Also in this case, the upper connecting tool 121 and the lower connecting tool 131 may be provided at positions displaced by approximately 90 degrees in the circumferential direction of the Z axis, which is the rotation axis of the twist. In this case, for example, the upper connecting tool 121 is made up of buttons, and the lower connecting tool 131 is made up of button holes. This button hole is provided at a position approximately 90 degrees offset from the corresponding button in the circumferential direction of the Z axis. With this configuration, the same effect as that of the present embodiment can be obtained.

The present invention is not limited to the above embodiments. The present invention can be variously modified or applied within the scope of the technical idea. The scope of such practice also belongs to the technical scope of the present invention.
