[0014] As shown in FIGS. 1 to 3, the backpack 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 portion 11, a backrest portion 12, and a fan opening 13.

[0016] As shown in FIG. 2, the storage portion 11 of the bag body 10 is a portion for storing items such as luggage, and is separated from other portions of the bag body 10 by a sheet-like member such as cloth or a plate-like member. Further, the bag body 10 is provided with a first fastener 14A for opening and closing an access opening for taking items in and out of the storage portion 11, and a handle 15.

[0017] The backrest portion 12 of the bag body 10 is a portion facing the user's back and is formed separately from the storage portion 11. In the embodiment, the backrest portion 12 is formed of a flexible plate-like material.

[0018] As shown in Fig. 2, the bag body 10 has a bottom space divided into a storage portion 11 at the lowermost part, and the blower fan 50 is accommodated in the bottom space of the bag body 10. Further, the lowermost part of the bag body 10 surrounding the bottom space of the bag body 10 is connected to the storage portion 11 via a second fastener 14B, and by opening and closing the second fastener 14B, the user can access the bottom space from the outside of the bag body 10.

[0019] Furthermore, the bag body 10 has a battery storage pocket 16 on the side portion. 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 a region other than the backrest portion 12 of the bag body 10. As shown in Fig. 3, in the embodiment, the fan opening 13 is formed on the bottom surface of the bag body 10.

[0021] A pair of shoulder straps 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 strap 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 discharge air from the inside of the bag body 10 toward the user's back or introduce air from the outside of the bag body 10 to the inside. In the 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 - 3 cm and is edged 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 holes 30. In the embodiment, as shown in Fig. 2, the first air flow path 40 is formed from the space between the backrest 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 through 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 through the fan opening 13, sends the air to the first air hole 30 through the first air flow path 40, and sends the air so as to blow it toward the user's back through the first air hole 30.

[0025] Also, in the embodiment, the blower fan 50 is electrically connected to the battery 51 via the USB cable 52 and sends air by the power supplied from the battery 51.

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

[0027] As described above with reference to FIGS. 1 to 3, according to the backpack of the embodiment, the blower fan 50 takes in air from the outside to the inside of the bag body 10 through the fan opening 13, sends the air to the first air hole 30 through the first air flow path 40, and sends the air so as to blow it onto the user's back through the first air hole 30. Therefore, in hot seasons such as summer, outside air can be introduced between the user's back and the backrest portion 12, inconveniences such as the back getting stuffy can be prevented, and the user can comfortably use the backpack even in hot seasons such as summer.

[0028] Also, according to the backpack of the embodiment, the external spacer 60 is attached to the backrest portion 12 and forms 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 flow rate of outside air between the user's back and the backrest portion 12 to cool the user's back, and the user can more surely and comfortably use the backpack even in hot seasons such as summer.

[0029] Next, referring to FIGS. 4 and 5, a second embodiment of the present invention will be described. FIG. 4 is a rear perspective view showing a backpack according to the second embodiment of the present invention. FIG. 5 is a cross-sectional view taken along the line B-B of the backpack in FIG. 4.

[0030] As shown in FIGS. 4 and 5, the backpack of the second embodiment further includes an internal spacer 70. The internal spacer 70 is disposed between the storage portion 11 and the backrest portion 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 in the shape of a quadrangular prism are erected on the backrest portion 12 so as to ensure ventilation in the first air flow path 40. Therefore, even when the luggage is stored in the storage portion 11 so that the storage portion 11 is full, the backrest portion 12 and the storage portion 11 do not come into close contact with each other and the first air flow path 40 is not blocked, and it is easy to introduce outside air with a sufficient flow rate to cool the user's back between the user's back and the backrest portion 12. The user can more reliably and comfortably use the backpack even in hot seasons such as summer.

[0032] Next, referring to FIGS. 6 and 7, a third embodiment of the present invention will be described. FIG. 6 is a cross-sectional view taken along the line D-D of the backpack according to the third embodiment of the present invention shown in FIG. 7. FIG. 7 is a cross-sectional view taken along the line C-C of the backpack in FIG. 6.

[0033] As shown in FIGS. 6 and 7, the backpack of the third embodiment, like the backpack of the second embodiment, further includes an internal spacer 70. The internal spacer 70 is disposed between the storage portion 11 and the backrest portion 12 so as 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 a constant interval between the housing portion 11 and the backrest portion 12 so as 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] Also in the third embodiment, as in the second embodiment, even when the luggage is stored in the storage portion 11 so that the storage portion 11 is full by the second internal spacer 70B, the backrest portion 12 and the storage portion 11 are in close contact with each other and the first air flow path 40 is not blocked, and it becomes easy to introduce outside air with a sufficient flow rate to cool the user's back between the user's back and the backrest portion 12. Thus, the user can more surely use the backpack comfortably even in hot seasons such as summer.

[0036] Further, in the third embodiment, the second internal spacer 70B has a plurality of ventilation holes 71 penetrating the second internal spacer 70B in the width direction. Therefore, ventilation in the first air flow path 40 can be ensured not only in the vertical direction but also in the horizontal direction of the bag body 10, and it becomes easy to introduce outside air with a sufficient flow rate to cool the user's back between the user's back and the backrest portion 12. Thus, the user can more surely use the backpack comfortably even in hot seasons such as summer.

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

[0038] As shown in FIGS. 8 and 9, different from the above-described embodiments, in the backpack of the fourth embodiment, the fan opening 13 is formed not on the bottom surface of the bag body 10 but on both side surfaces at the lowermost part of the bag body 10, and the blower fan 50 is 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 side surfaces at the lowermost part 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. As a result, the bottom space at the lowermost part of the bag body 10 has a larger size in the height direction than in each of the above embodiments. Therefore, for example, a lunch box can be accommodated in the bottom space at the lowermost part of the bag body 10. Even when the internal temperature of the accommodation part 11 becomes higher than the outside air temperature due to the user's body temperature or direct sunlight, the temperature rise of the bottom space can be suppressed by the blowing of the blower fans 50, and the temperature rise of the contents such as a lunch box, which is not preferably at a high temperature, can be suppressed.

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

[0041] As shown in FIGS. 10 and 11, the backpack of the fifth embodiment further includes a second air hole 90. The second air hole 90 is formed in the backrest portion 12 so as to communicate the outside of the bag body 10 with the first air flow path 40. When the blower fan 50 sends air so that air is discharged from the inside of the bag body 10 toward the user's back through the first air hole 30, air is discharged from the inside of the bag body 10 toward the user's neck.

[0042] In the embodiment, the second air hole 90 is disposed at the upper part of the bag body 10, which is closer to the user's neck than the first air hole 30 and all the external spacers 60 in a state where the user wears the backpack, in the backrest portion 12 so that air can be effectively discharged toward the user's neck.

[0043] Except for the above, the backpack of the fifth embodiment is the same as the backpack of the first embodiment. According to the backpack of the fifth embodiment, not only can outside air be introduced between the user's back and the backrest portion 12, but also air can be blown to the user's neck, and the backpack can be used more comfortably even in hot seasons such as summer.

[0044] Next, referring to FIGS. 12 and 13, a sixth embodiment of the present invention will be described. FIG. 12 is a rear view showing a backpack according to the sixth embodiment of the present invention. FIG. 13 is a cross-sectional view taken along the line G-G of the backpack in FIG. 12.

[0045] As shown in FIGS. 12 and 13, the backpack of the sixth embodiment includes a second air hole 90, similar to the backpack of the fifth embodiment. Further, the backpack of the sixth embodiment includes a wind direction adjustment plate 91. The wind direction adjustment plate 91 adjusts the wind direction so that the air discharged from the second air hole 90 flows along the user's neck muscles.

[0046] Also, the wind direction adjustment plate 91 also functions as a lid plate for opening and closing the second air hole 90, and has a finger hook portion 92 for hanging a fingertip when opening the second air hole 90. In the embodiment, the wind direction adjustment plate 91 is swingably connected to the backrest portion 12 at one end in the vertical direction of the bag body 10 (the lower end in FIG. 13), and both side ends are connected to the backrest portion 12 by a flexible sheet-like member such as cloth.

[0047] Except for the above, the backpack of the sixth embodiment is the same as the backpack of the first embodiment. According to the backpack of the sixth embodiment, not only can outside air be introduced between the user's back and the backrest portion 12, but also air can be blown along the neck muscles to increase the user's coolness, and the backpack can be used more comfortably even in hot seasons such as summer.

[0048] Also, when the blowing to the neck muscles is not required, the second air hole 90 can be closed by the wind direction adjustment plate 91 to stop the blowing to the neck muscles and blow only to the back, and the optimum blowing can be realized to maximize the user's comfort according to 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 implemented in various aspects without departing from the gist thereof (for example, refer to the following (1) to (2)).
