Description

[Technical field]

[0001] The present invention relates to a backpack, school bag, or other backpack-type bag that is carried by the user on the back. [Background technology]

[0002] A backpack-type bag is known that has a cushioning material provided on the back portion that faces the user's back.

[0003] The cushioning material is formed of an elastic plate-like body, and serves to reduce shocks and the like on the user's back, thereby protecting the body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2023-167242 A [Patent Document 1] Patent No. 6829751 Summary of the Invention [Problem to be solved by the invention]

[0005] When a conventional cushioning material made of an elastic material is in contact with a user's back for a long period of time, there is a problem that the back becomes stuffy.

[0006] Furthermore, the cushioning material has no other purpose than to protect the user's back through its elasticity, and therefore has a problem of lacking versatility.

[0007] The object of the present invention is to provide a backpack-type bag that solves these problems. [Means for solving the problem]

[0008] Therefore, the first means of the present invention is a backpack bag that is carried by the user by being worn on the back, and is provided with cushioning material on the backrest that faces the user's back, and the cushioning material is removably attached to the backrest and has a shape and size that can be used as a cushion when removed from the backrest, and the backrest is provided with a breathable covering sheet that covers the surface of the cushioning material when it is attached.

[0009] In addition, the second means of the present invention is a backpack-type bag that is carried by the user by being worn on the back, and a pocket with an opening at the top is provided on the backrest portion facing the user's back, and cushioning material is removably inserted into the pocket, and when inserted into the pocket, the cushioning material is formed by an elastic disk-like body that is interposed between the backrest portion of the bag and the user's back, and when removed from the pocket, it is formed in a shape and size that can be used as a cushion, and the pocket is formed by a breathable covering sheet that covers the surface of the cushioning material when it is inserted.

[0010] In an embodiment of the present invention, the covering sheet is formed of a net sheet having a mesh.

[0011] The cushioning material is a disc-shaped body made of urethane foam of a predetermined thickness, covered with a woven or woven sheet cover. Effect of the Invention

[0012] According to this invention, the cushioning material can be removed from the backrest of the bag and used as a seat cushion. Therefore, even in an environment where a seat cushion is needed, the user does not need to carry a separate seat cushion, which is extremely convenient.

[0013] When the cushioning material is attached to the backrest of the bag, it is configured so that the cushioning material does not come into contact directly with the user's back, but comes into contact via a breathable covering sheet, thereby preventing the back from becoming stuffy. [Brief description of the drawings]

[0014] [Figure 1] 1A and 1B show an embodiment of a bag according to the present invention, in which (A) is a perspective view seen from the front, and (B) is a perspective view seen from the back. [Diagram 2] FIG. 2 is a perspective view of the bag with the cushioning material removed from the pocket. [Diagram 3] 13 shows the state in which the cushioning material is inserted into the pocket, (A) being a rear view and (B) being a central longitudinal cross-sectional view. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0016] The bag 1 is configured as a backpack-type bag that is carried by the user by being worn on the back. For this reason, a back support portion 3 is formed on the back side of the bag body 2. For example, as shown in Fig. 3(B), the back support portion 3 is formed by disposing a plate-shaped core material 4 on the back side of the bag body 2, but is not limited to this.

[0017] A pair of left and right shoulder belts 5, 5 extending in the vertical direction of the backrest portion 3 are provided, and the bag can be carried on the user's back by hanging the shoulder belts 5, 5 on both shoulders, with the backrest portion 3 facing the user's back.

[0018] In the illustrated example, the bag body 2 is provided with a flap 6 for freely opening and closing the top opening, and a small bag 7 for storing small items is provided on the front side, but both of these configurations are optional.

[0019] In the drawings, the bag 1 is shown as a rucksack (backpack), but it may also be a school bag or other type of bag worn on the back.

[0020] In such a backpack-type bag, a cushioning material 8 is arranged on the backrest portion 3, and the cushioning material 8 can be attached to the backrest portion 3 in a detachable manner.

[0021] In this case, the cushioning material 8 has a plate-like body 8a formed of thick urethane foam having a predetermined thickness covered with a woven sheet cover 8b, and has a shape and size that can be used as a seat cushion 9. In the illustrated embodiment, the cushioning material 8 is formed by using a generally used compact seat cushion 9. In other words, it is characterized in that the seat cushion 9 is used as the cushioning material 8 of the bag 1.

[0022] As a means for attaching the cushioning material 8, a pocket 10 with an opening at the top is provided in the back support portion 3, and the cushioning material 8 can be attached by being inserted into the pocket 10 in a freely detachable manner.

[0023] The pocket 10 is formed of a breathable covering sheet 11. In this case, the covering sheet 11 covers the surface of the cushioning material 8 inserted in the pocket 10, and forms a gap between the user's back and the cushioning material 8 that ensures breathability.

[0024] Preferably, the covering sheet 11 is made of a net sheet 11a having a mesh. In the illustrated embodiment, the edging strips 11b and 11c provided on both side edges and the lower edge of the net sheet 11a are fixed to the backrest portion 3, thereby forming the pocket 10.

[0025] A lateral strip 11d provided along the upper edge forms the opening edge of the pocket 10. In this case, the lateral strip 11d is preferably formed of an elastic strip that is elastically stretchable, so that the opening of the pocket 10 can be formed to be expandable and can function as a retaining means for the cushioning material 8 with the opening normally contracted.

[0026] As a result of the above configuration, the cushioning material 8 can be removed from the backrest portion 3 of the bag 1. In other words, it can be taken out from the pocket 10. As a result, the cushioning material 8 cannot be used as a cushion 9, so even in an environment where a cushion is needed, the user does not need to carry a separate cushion, which is very convenient.

[0027] In other words, a cushion 9 is used which is made of a thick urethane foam plate 8a covered with a woven sheet cover 8b, and the feature of this invention is that such a cushion 9 is configured so as to be usable as the cushioning material 8 of the bag 1.

[0028] When the cushioning material 8 is used attached to the back support portion 3 of the bag 1, it can be easily attached with one touch by inserting it into the pocket 10 from the opening, and the back of the user carrying the bag 1 can be protected with the elastic cushioning material 8 in contact with the back.

[0029] At this time, the cushioning material 8 is configured so that it does not come into direct contact with the user's back, but comes into contact with the user's back via the breathable covering sheet 11, so that the user's back can be suitably prevented from becoming stuffy.
