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

[0014] As shown in FIGS. 1 to 3, the backpack bag of the embodiment includes 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 an opening 13 for a fan.

[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 fastener 14A for opening and closing an 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 the embodiment, the back support portion 12 is formed from a flexible plate-shaped material.

[0018] 2, the bag body 10 has, at its lowest portion, a bottom space separated from the storage section 11, and the blower fan 50 is stored in the bottom space of the bag body 10. In addition, the bottom portion of the bag body 10 surrounding 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. A battery 51 for supplying power to the blower fan 50 is stored in the battery storage pocket 16.

[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. In the embodiment, the fan opening 13 is formed in the bottom surface of the bag body 10, as shown in FIG.

[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 the embodiment, one end of the shoulder belt 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 holes 30 are formed in the backrest portion 12 and release 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 holes 30 are formed in the backrest portion 12, and each first air hole 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 Fig. 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 lowermost part of the bag body 10.

[0024] 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. In the 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 to the first air hole 30 via the first air flow path 40, and sends the air via the first air hole 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 the USB cable 52, and blows air using the 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 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 the 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 to the first air hole 30 via the first air flow path 40, and sends the air through the first air hole 30 so as to be blown onto the back of the user. Therefore, in hot seasons such as summer, outside air can be introduced between the user's back and the back support 12, preventing inconveniences such as the back becoming stuffy, and allowing the user to use the backpack bag comfortably even in hot seasons such as summer.

[0028] Furthermore, according to the backpack bag of the embodiment, an external spacer 60 is attached to the back support portion 12, forming a second air flow path 80 between the user's back and the first air hole 30. Therefore, the first air hole 30 is not blocked by the user's back, and it becomes 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, so that the user can more reliably use the backpack bag comfortably even in hot seasons such as summer.

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

[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 with luggage, the back support portion 12 and the storage portion 11 do not come into close contact with each other to block the first air flow path 40, and it becomes 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, so that the user can more reliably use the backpack comfortably even in hot seasons such as summer.

[0032] Next, a third embodiment of the present invention will be described with reference to Fig. 6 and Fig. 7. Fig. 6 is a cross-sectional view taken along line DD in Fig. 7, showing a backpack bag according to the third embodiment of the present invention. Fig. 7 is a cross-sectional view taken along line CC in Fig. 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 so as to ensure ventilation in the first air flow path 40.

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

[0035] In the third embodiment, as in the second embodiment, the second internal spacer 70B prevents the backrest 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 backrest 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 inner spacer 70B has a plurality of ventilation holes 71 that pass through the second inner 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 portion 12 to cool the user's back, allowing the user to use the backpack more reliably and comfortably even in hot seasons such as summer.

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

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

[0039] The fan openings 13 are formed on both side surfaces at the bottom of the bag body 10, and the blower fans 50 are installed facing 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 made larger in height than the above-mentioned embodiments. Therefore, for example, a lunch box 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 blower fan 50 can suppress the temperature rise in the bottom space, and the temperature rise of stored items such as lunch boxes, which should not be kept at high temperatures, can be suppressed.

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

[0041] 10 and 11, the backpack bag of the fifth embodiment further includes a second air hole 90. The second air hole 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 so that the air is discharged from the inside of the bag body 10 toward the back of the user through the first air hole 30, the air is discharged from the inside of the bag body 10 toward the neck of the user.

[0042] In this embodiment, the second air hole 90 is disposed in the upper part of the bag body 10 in the back support portion 12, closer to the user's neck than the first air hole 30 and all of the external spacers 60 when the user is wearing the backpack, 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. According to the backpack bag of the fifth embodiment, not only can outside air be introduced between the back of the user and the back support portion 12, but air can also be blown to the neck of the user, making the backpack bag more comfortable to use even in hot seasons such as summer.

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

[0045] 12 and 13, the backpack bag of the sixth embodiment has a second air hole 90, similar to the backpack bag of the fifth embodiment. The backpack bag of the sixth embodiment also has an air direction adjustment plate 91. The air direction adjustment plate 91 adjusts the air direction so that the air discharged from the second air hole 90 flows along the user's neck.

[0046] The airflow direction adjustment plate 91 also functions as a cover plate for opening and closing the second air hole 90, and has a finger hook 92 for hooking a fingertip when opening the second air hole 90. In the embodiment, the airflow direction adjustment plate 91 is swingably connected to the backrest 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 backrest 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 portion 12, but also allows air to be blown along the user's neck to cool the user down, allowing the user to use the backpack bag more comfortably even in hot seasons such as summer.

[0048] In addition, when there is no need to blow air to the neck, the second air hole 90 can be closed using the air direction adjustment plate 91 to stop the air being blown to the neck and send air only to the back, thereby achieving 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-described embodiments, and can be embodied in various forms without departing from the spirit of the present invention (for example, see (1) to (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 backrest 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 backrest portion 12 to prevent the storage section 11 and the backrest portion 12 from coming into close contact with each other and blocking the first air flow path 40.
