(A) is a side view showing an example of the use condition of the backpack 1 carried on the back, and (B) is a side view showing an example of the use condition of the backpack 1 with the position of the lower end of the shoulder belt changed. It is a diagram. It is a figure which shows the modification of the backpack 1 of FIG. 4 is a diagram showing an example of a protruding member 52; FIG. It is a figure which shows the state which removed the 1st member 521 from the protrusion member 52 of FIG.

An example of an embodiment of the backpack of the present invention will be described below with reference to FIG. FIG. 1 is a diagram showing an embodiment of the backpack of the present invention.

As shown in FIG. 1, a backpack 1 of this embodiment has a storage space for storing luggage, a bag body 2 having a back support surface BS facing the user's back, and a back of the bag body 2. It has two shoulder belts 3 and 4 (hereinafter referred to as first shoulder belt 3 and second shoulder belt 4) attached to the contact surface BS side. Further, in the back support surface BS, a support portion 5 having a shape projecting so as to support the spine between the shoulder blades of the user, and a cover portion 7 covering the left, right, and lower peripheral edge portions of the back support surface BS. , is provided.

The support portion 5 is composed of a base member 51 and a projecting member 52 attached to this base member 51 . An upper hole 53 is formed in the upper portion of the base member 51 . The belt member 6 attached to the upper part of the bag body 2 is folded back through the upper hole 53 and fixed using an adjuster 61. With this configuration, the bag body 2 and the support portion 5 are connected. there is The adjuster 61 is an example of an adjuster capable of adjusting the length between the bag main body 2 and the support portion 5 (structure capable of adjusting the vertical position of the support portion 5). The material of the protruding member 52 is ABS resin, but EVA resin may be used to obtain flexibility and elasticity, and the material is not limited.

Lower holes 54 and 55 (hereinafter referred to as a first lower hole 54 and a second lower hole 55) are formed at two locations on the left and right sides of the lower portion of the base member 51, respectively. The first shoulder belt 3 is folded back through one of the plurality of through holes 8 formed in the cover portion 7, and is then folded back through the first lower hole 54 and fixed using the adjuster 31. there is The second shoulder belt 4 is folded back through one of the plurality of through holes 8 formed in the cover portion 7, and further folded back through the second lower hole 55 and fixed using the adjuster 41. .

FIG. 2(A) is a side view showing an example of a usage state in which the user U puts the first shoulder belt 3 and the second shoulder belt 4 on his shoulders and carries the backpack 1 on his back. 2(A) and FIG. 2(B), which will be described later, assume that the length of the belt member 6 is adjusted so that the support portion 5 is arranged between the shoulder blades of the user U. do. Also, the second shoulder belt 4 is assumed to be in the same state as the first shoulder belt 3, and illustration thereof is omitted. In the state shown in FIG. 2A, the pressure from the support portion 5 is applied to the spine between the shoulder blades of the user U, thereby encouraging the user U to take a better posture.

The pressure applied from the support portion 5 to the user U changes according to the tension applied to each of the first shoulder belt 3 and the second shoulder belt 4. For example, when the lengths of the first shoulder belt 3 and the second shoulder belt 4 are shortened, the tension applied to each of the first shoulder belt 3 and the second shoulder belt 4 increases, and the pressure from the support portion 5 decreases. It becomes higher, and the effect of posture correction can be further improved.

In the backpack 1, the first shoulder belt 3 and the second shoulder belt 4 pass through one of the plurality of through holes 8 formed in the cover portion 7 and are folded back. Here, by changing the through hole 8 through which the first shoulder belt 3 and the second shoulder belt 4 are passed, the positions of the lower ends of the first shoulder belt 3 and the second shoulder belt 4 can be changed. FIG. 2(B) shows a state in which the position of the lower end side of the first shoulder belt 3 has been changed to a position closer to the support portion 5 than in FIG. 2(A). In the state of FIG. 2(B), the force of pulling the bag body 2 on the lower end side of each of the first shoulder belt 3 and the second shoulder belt 4 is reduced by the support portion 5 as compared with the state of FIG. 2(A). It can be applied to a close position, and the pressure from the support portion 5 can be generated more reliably.

As described above, it is possible to encourage a better posture according to the tension applied to each of the first shoulder belt 3 and the second shoulder belt 4, but depending on the size, shape, and posture of the user, If this tension is too strong, there is a risk of obstructing the flow of blood and lymph. However, in the backpack 1 described above, by adjusting the positions of the lower end sides of the first shoulder belt 3 and the second shoulder belt 4, the tension of these

belts

3 and 4 is not excessively increased, and the tension from the support portion 5 is reduced. Appropriate pressure can be obtained. In addition, even if the tension is somewhat strong, the backpack 1 can be easily removed unlike a so-called posture corrector, so that it can be used every day when commuting to work or school. By repeating use in a short period of time where the swelling does not increase, you can easily get the opportunity to correct your posture.

In addition, in the backpack 1 of the present embodiment, the configuration in which the through holes 8 are changed when changing the positions of the lower ends of the first shoulder belt 3 and the second shoulder belt 4 has been described. may be provided at the respective ends of the first shoulder belt 3 and the second shoulder belt 4, and connecting members connectable to these ends may be provided at a plurality of locations in place of the through holes 8. In other words, any structure may be used as long as the positions of the lower end sides of the first shoulder belt 3 and the second shoulder belt 4 can be changed.

Note that, as in the backpack 1 of the present embodiment, when the first shoulder belt 3 and the second shoulder belt 4 folded back on the lower end side are each connected to the support portion 5, the first The respective tensions of the shoulder belt 3 and the second shoulder belt 4 are directly transmitted to the support portion 5, and pressure from the support portion 5 can be generated efficiently. Further, in the case where the vertical position of the support portion 5 is adjustable as in the backpack 1 of the present embodiment, the support portion 5 is adjusted to an appropriate position according to the body shape of the user. It can encourage you to have better posture.

In the backpack 1 shown in FIG. 1, a plurality of through-holes 8 are formed in the cover portion 7 that covers the left, right, and lower peripheral portions of the back support surface BS of the bag body 2. However, the cover portion 7 is provided. It may be configured without FIG. 3 shows a modification of the backpack 1 shown in FIG. FIG. 3 shows a backpack 1a in which a plurality of through holes 8 are formed in the back support surface BS of the bag body 2 and the support portion 5 is arranged inside the bag body 2. As shown in FIG. In addition, in FIG. 3, the configuration arranged inside the bag body 2 is indicated by a dotted line. Other configurations are the same as those of the backpack 1 shown in FIG. In this backpack 1a as well, when the user puts the first shoulder belt 3 and the second shoulder belt 4 on the shoulders, pressure is applied from the support part 5 to the spine between the shoulder blades of the user, The posture can be urged to become a better posture.
