[0004] However, in the backpack bag described in Patent Document 1, the back support of the bag body covers a certain area of ​​the user's back, which can cause inconvenience such as the back becoming stuffy, especially during hot seasons such as summer, making it difficult to use comfortably.

[0005] The present invention was made in consideration of the above-mentioned problems, and its purpose is to provide a backpack bag that can introduce outside air at least between the user's back and the back support, making it comfortable to use even during hot seasons such as summer.

[0006] The backpack bag disclosed herein comprises a bag body (10), a pair of left and right shoulder straps (20), a first air vent (30), a first air flow path (40), and a blower fan (50). The bag body (10) has a storage section (11) for storing items, a back support section (12) facing the user's back, and a fan opening (13) formed in an area other than the back support section (12). The pair of left and right shoulder straps (20) are attached to the bag body (10) and support the bag body (10) on the user's shoulders. The first air vent (30) is formed in the back support section (12) and discharges air from the inside of the bag body (10) toward the user's back, or introduces air from the outside of the bag body (10) into the inside. The first air flow path (40) is disposed inside the bag body (10) and communicates with the outside of the bag body (10) via the first air hole (30). The blower fan (50) is installed in the fan opening (13) and sends air between the first air hole (30) and the fan opening (13) via the first air flow path (40).

[0007] The backpack bag disclosed herein further comprises an external spacer (60) attached to the back support portion (12) to form a second air flow path (80) between the user's back and the first air hole (30).

[0008] The backpack bag disclosed herein further comprises an internal spacer (70) disposed between the storage section (11) and the back support section (12) to ensure ventilation in the first air flow path (40).

[0009] The backpack bag disclosed herein further comprises a second air vent (90). The second air vent (90) is formed in the back support portion (12) so as to connect the outside of the bag body (10) with the first air flow path (40), and when the blower fan (50) sends air from the inside of the bag body (10) through the first air vent (30) so that the air is discharged from the inside of the bag body (10) toward the user's back, the second air vent (90) discharges air from the inside of the bag body (10) toward the user's neck.

[0012] A backpack according to an embodiment of the present invention will be described in detail below with reference to the drawings. Note that the embodiment described below is a preferred example for carrying out the present invention, and therefore various technical limitations are imposed thereon. However, the present invention is not limited to this embodiment unless otherwise specified in the following description to the effect that the invention is limited thereto.

[0013] <Embodiments> A backpack bag according to a first embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 is a rear view showing the backpack bag according to the first embodiment of the present invention. Figure 2 is a cross-sectional view of the backpack bag shown in Figure 1 taken along the line A-A. Figure 3 is a bottom view of the backpack bag shown in Figure 1.

[0014] As shown in FIGS. 1 to 3, the backpack bag of this embodiment comprises a bag body 10, a pair of left and right shoulder straps 20, a first air hole 30, a first air flow path 40, and a blower fan 50.

[0015] The bag body 10 has a storage section 11, a back support section 12, and a fan opening 13.

[0016] 2, the storage section 11 of the bag body 10 is a section for storing items such as luggage, and is separated from other sections of the bag body 10 by a sheet-like member such as cloth or a plate-like member. The bag body 10 is also provided with a first zipper 14A for opening and closing an access opening for putting items in and taking items out of the storage section 11, and a handle 15.

[0017] The back support portion 12 of the bag body 10 is a portion that faces the back of the user and is formed separately from the storage portion 11. In this embodiment, the back support portion 12 is formed from a flexible plate-shaped material.

[0018] 2, the bag body 10 has a bottom space at its lowest portion that is separated from the storage section 11, and the blower fan 50 is housed in the bottom space of the bag body 10. The bottom portion of the bag body 10 that surrounds the bottom space of the bag body 10 is connected to the storage section 11 via a second fastener 14B, and the user can access the bottom space from outside the bag body 10 by opening and closing the second fastener 14B.

[0019] Furthermore, the bag body 10 has a battery storage pocket 16 on the side thereof. The battery storage pocket 16 stores a battery 51 for supplying power to the blower fan 50.

[0020] The fan opening 13 of the bag body 10 is formed in an area of ​​the bag body 10 other than the back support portion 12. As shown in Figure 3, in this embodiment, the fan opening 13 is formed in the bottom surface of the bag body 10.

[0021] The pair of shoulder belts 20 are attached to the bag body 10 and support the bag body 10 on both shoulders of the user. In this embodiment, one end of the shoulder belts 20 is connected to the upper part of the bag body 10 and the other end is connected to the lower part of the bag body 10.

[0022] The first air vents 30 are formed in the back support portion 12 and discharge air from the inside of the bag body 10 toward the back of the user, or introduce air from the outside of the bag body 10 into the inside. In this embodiment, a plurality of first air vents 30 are formed in the back support portion 12, and each first air vent 30 is a circular hole with a diameter of 1 to 3 cm and is bordered by a ring-shaped metal fitting.

[0023] The first air flow path 40 is disposed inside the bag body 10 and communicates with the outside of the bag body 10 via the first air hole 30. In this embodiment, as shown in Figure 2, the first air flow path 40 is formed by the space between the back support portion 12 and the storage portion 11 and the bottom space at the bottom of the bag body 10.

[0024] The blower fan 50 is installed in the fan opening 13 and sends air between the first air holes 30 and the fan opening 13 via the first air flow path 40. In this embodiment, the blower fan 50 takes in air from the outside to the inside of the bag body 10 via the fan opening 13, sends the air via the first air flow path 40 to the first air holes 30, and sends the air via the first air holes 30 so as to blow the air towards the back of the user.

[0025] In this embodiment, the blower fan 50 is electrically connected to the battery 51 via a USB cable 52 and blows air using power supplied from the battery 51 .

[0026] The external spacer 60 is attached to the back support portion 12 and forms a second air flow path 80 between the user's back and the first air hole 30. In this embodiment, the external spacer 60 is a cushion made of a plastic foam material such as polyurethane foam, and is attached to the back support portion 12 so as to have a thickness of 2 to 4 cm in an uncompressed state.

[0027] 1 to 3, according to the backpack bag of this embodiment, the blower fan 50 takes in air from the outside of the bag body 10 to the inside through the fan opening 13, sends the air through the first air flow path 40 to the first air hole 30, and then sends the air through the first air hole 30 so that it is blown onto the user's back. Therefore, during hot seasons such as summer, outside air can be introduced between the user's back and the back support 12, preventing inconveniences such as stuffiness on the back, and allowing the user to use the backpack bag comfortably even during hot seasons such as summer.

[0028] Furthermore, with the backpack bag of this embodiment, an external spacer 60 is attached to the back support 12, forming a second air flow path 80 between the user's back and the first air hole 30. This prevents the user's back from blocking the first air hole 30, making it easy to introduce a sufficient amount of outside air between the user's back and the back support 12 to cool the user's back, allowing the user to use the backpack bag more reliably and comfortably, even in hot seasons such as summer.

[0029] Next, a second embodiment of the present invention will be described with reference to Figures 4 and 5. Figure 4 is a rear perspective view showing a backpack bag according to the second embodiment of the present invention. Figure 5 is a cross-sectional view of the backpack bag shown in Figure 4 taken along the line B-B.

[0030] 4 and 5, the backpack bag of the second embodiment further includes an internal spacer 70. The internal spacer 70 is disposed between the storage section 11 and the back support section 12 so as to ensure ventilation in the first air flow path 40.

[0031] In the second embodiment, a plurality of first internal spacers 70A each having a rectangular prism shape are erected on the back support portion 12 to ensure ventilation in the first air flow path 40. Therefore, even when the storage portion 11 is filled to capacity with luggage, the back support portion 12 and the storage portion 11 do not come into close contact with each other, blocking the first air flow path 40. This makes it easy to introduce a sufficient amount of outside air between the user's back and the back support portion 12 to cool the user's back, allowing the user to use the backpack bag more reliably and comfortably, even in hot weather such as summer.

[0032] Next, a third embodiment of the present invention will be described with reference to Figures 6 and 7. Figure 6 is a cross-sectional view of a backpack bag according to the third embodiment of the present invention taken along the line D-D in Figure 7. Figure 7 is a cross-sectional view of the backpack bag taken along the line C-C in Figure 6.

[0033] 6 and 7, the backpack bag of the third embodiment, like the backpack bag of the second embodiment, further includes an internal spacer 70. The internal spacer 70 is disposed between the storage section 11 and the back support section 12 to ensure ventilation in the first air flow path 40.

[0034] In the third embodiment, a plurality of thick plate-shaped second internal spacers 70B are arranged in parallel at regular intervals between the storage section 11 and the back support section 12 to ensure ventilation in the first air flow path 40. Each second internal spacer 70B has a plurality of ventilation holes 71. The plurality of ventilation holes 71 penetrate the second internal spacer 70B in the width direction.

[0035] In the third embodiment, as in the second embodiment, the second internal spacer 70B prevents the back support portion 12 and the storage portion 11 from coming into close contact with each other and blocking the first air flow path 40, even when luggage is stored in the storage portion 11 so that the storage portion 11 is full, making it easier to introduce a sufficient amount of outside air between the user's back and the back support portion 12 to cool the user's back, allowing the user to more reliably use the backpack comfortably even during hot seasons such as summer.

[0036] In the third embodiment, the second internal spacer 70B has a plurality of ventilation holes 71 that penetrate the second internal spacer 70B in the width direction. This ensures ventilation in the first air flow path 40 not only in the vertical direction of the bag body 10 but also in the horizontal direction, making it easy to introduce a sufficient amount of outside air between the user's back and the back support 12 to cool the user's back, allowing the user to use the backpack more comfortably even in hot seasons such as summer.

[0037] Next, a fourth embodiment of the present invention will be described with reference to Figures 8 and 9. Figure 8 is a rear view showing a backpack bag according to the fourth embodiment of the present invention. Figure 9 is a cross-sectional view of the backpack bag of Figure 8 taken along the line E-E.

[0038] As shown in Figures 8 and 9, the backpack bag of the fourth embodiment differs from the above-described embodiments in that the fan openings 13 are formed on both sides of the lowermost part of the bag body 10 rather than on the bottom surface of the bag body 10, and the blower fans 50 are installed so as to face each other in the width direction of the bag body 10.

[0039] The fan openings 13 are formed on both sides of the bottom of the bag body 10, and the blower fans 50 are installed so as to face each other in the width direction of the bag body 10, so that the bottom space at the bottom of the bag body 10 is larger in height than in the above-described embodiments. Therefore, a lunch box, for example, can be stored in the bottom space at the bottom of the bag body 10, and even if the internal temperature of the storage section 11 becomes higher than the outside temperature due to the user's body temperature or direct sunlight, the air blown by the blower fan 50 can prevent the temperature from rising in the bottom space, thereby preventing the temperature from rising for stored items such as lunch boxes that should not be exposed to high temperatures.

[0040] Next, a fifth embodiment of the present invention will be described with reference to Figures 10 and 11. Figure 10 is a rear view showing a backpack bag according to the fifth embodiment of the present invention. Figure 11 is a cross-sectional view of the backpack bag shown in Figure 10 taken along the line F-F.

[0041] 10 and 11 , the backpack bag of the fifth embodiment further includes a second air vent 90. The second air vent 90 is formed in the back support portion 12 so as to connect the outside of the bag body 10 with the first air flow path 40, and when the blower fan 50 blows air from the inside of the bag body 10 toward the user's back through the first air vent 30, the second air vent 90 discharges air from the inside of the bag body 10 toward the user's neck.

[0042] In this embodiment, the second air vent 90 is arranged in the upper part of the bag body 10, in the back support portion 12, which is closer to the user's neck than the first air vent 30 and all of the external spacers 60 when the user is wearing the backpack bag, so that air can be effectively released toward the user's neck.

[0043] Other than the above, the backpack bag of the fifth embodiment is similar to the backpack bag of the first embodiment. The backpack bag of the fifth embodiment not only allows outside air to be introduced between the user's back and the back support 12, but also blows air around the user's neck, making the backpack bag more comfortable to use during hot seasons such as summer.

[0044] Next, a sixth embodiment of the present invention will be described with reference to Figures 12 and 13. Figure 12 is a rear view showing a backpack bag according to the sixth embodiment of the present invention. Figure 13 is a cross-sectional view of the backpack bag of Figure 12 taken along the line G-G.

[0045] 12 and 13 , the backpack bag of the sixth embodiment, like the backpack bag of the fifth embodiment, is equipped with a second air vent 90. The backpack bag of the sixth embodiment also has a wind direction adjusting plate 91. The wind direction adjusting plate 91 adjusts the wind direction so that the air released from the second air vent 90 flows along the user's neck.

[0046] The airflow direction adjusting plate 91 also functions as a cover plate for opening and closing the second air hole 90, and has a finger hook 92 on which a fingertip is hooked when opening the second air hole 90. In this embodiment, the airflow direction adjusting plate 91 is swingably connected to the back support portion 12 at one end (the lower end in FIG. 13 ) in the up-down direction of the bag body 10, and both side ends are connected to the back support portion 12 by a flexible sheet-like member such as cloth.

[0047] Other than the above, the backpack bag of the sixth embodiment is similar to the backpack bag of the first embodiment. The backpack bag of the sixth embodiment not only allows outside air to be introduced between the user's back and the back support 12, but also allows air to be blown along the user's neck to increase the user's cooling sensation, making the backpack bag more comfortable to use even in hot seasons such as summer.

[0048] Furthermore, when airflow to the nape of the neck is not required, the second air hole 90 can be closed using the airflow direction adjustment plate 91, stopping the airflow to the nape of the neck and sending air only to the back, thereby realizing optimal airflow to maximize the user's comfort depending on the situation.

[0049] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 13). However, the present invention is not limited to the above embodiments, and can be embodied in various forms without departing from the spirit of the present invention (see, for example, (1) and (2) below).

[0050] (1) In each of the above embodiments, the blower fan 50 blows air onto the user's back, but the blower fan 50 may also introduce outside air between the user's back and the back support portion 12 by blowing air from the outside to the inside of the bag body 10 through the first air hole 30.

[0051] (2) In the above fifth and sixth embodiments, as in the second or third embodiment, a first internal spacer 70A or a second internal spacer 70B can be arranged between the storage section 11 and the back support section 12 to prevent the storage section 11 and the back support section 12 from coming into close contact with each other and blocking the first air flow path 40.
