Description

  The present invention relates to a school bag.

  A user of the school bag may desire to attach a decorative part to the school bag according to his / her preference. For example, Japanese Patent Application Laid-Open No. 2011-194112 (Patent Document 1) discloses a school bag to which a decorative part selected by a purchaser is attached afterwards. In this school bag, a decorative part is fixed at a position facing the front of the body when the school bag on the back belt is carried. As the decorative parts, desired ones are selected from many kinds of decorative parts by the purchaser of the school bag.

  The selected decorative part is attached to the back strap as follows. A pair of attachment holes are provided on both sides of the position facing the front of the body when a tool such as a punch is used to carry the backpack of the backpack. A mounting member inserted in advance in the insertion ring of the selected decorative part is overlapped on the front surface of the backpack. A caulking rod is inserted through the through hole and the mounting hole in a state where the through holes at both ends of the mounting member are aligned with the pair of mounting holes of the backpack, and the caulking rod is caulked. Thus, the decorative part is fixed at a position facing the front of the body when the backpack of the backpack is carried on the back.

JP 2011-194112 A

  In the school bag described in the above publication, one decorative part selected from many types of decorative parts by the purchaser of the school bag is attached. However, it is not described that a plurality of decorative parts are exchanged according to preference. Further, in the school bag described in the above publication, the attachment member inserted in advance through the insertion ring of the selected decorative part is caulked to the shoulder strap. Therefore, in order to replace the decorative part, it is necessary to break the caulking ridge, remove the attachment member from the back strap, and remove the attachment member from the insertion ring of the decorative part. Then, it is necessary to insert the attachment member into the insertion ring of the new decorative part and caulk the attachment member to the shoulder strap. Therefore, it is difficult to replace the decorative part.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a school bag having a detachable member that can be easily replaced with a simple structure and can improve decorativeness. It is.

  The school bag of the present invention includes a main body having an opening, a shoulder belt connected to the main body, a lid connected to the main body so that the opening can be opened and closed, and at least the main body, the shoulder belt, and the lid. The eyelet member has a hole penetrating any one of the front surface and the back surface, and is provided so as to sandwich the front surface and the back surface, and an attaching / detaching member provided detachably on the eyelet member. The detachable member is located on the front side in a state of being attached to the eyelet member, and is located on the back side in a state of being attached to the eyelet member and having a surface portion having a diameter larger than the diameter of the hole of the eyelet member on the surface. The back surface has a diameter larger than the diameter of the hole of the eyelet member and is smaller than the diameter of the front surface portion, and is provided between the front surface portion and the back surface portion, and is inserted through the hole of the eyelet member. Including possible shank. The back surface portion can be elastically deformed and can be engaged with at least one of the eyelet member and the back surface after passing through the hole of the eyelet member.

  In the school bag of the present invention, since the detachable member is composed of the front surface portion, the back surface portion, and the shaft portion, it has a simple structure. Further, the back surface portion of the detachable member has a diameter smaller than the diameter of the front surface portion, is elastically deformable, and is configured to be able to engage with at least one of the eyelet member and the back surface after passing through the hole of the eyelet member. ing. For this reason, a back surface part can pass easily the hole of an eyelet member. Therefore, the detachable member can be easily attached to and detached from the hole of the eyelet member. Moreover, the decorativeness of the school bag can be improved by attaching a decorative member to the eyelet member.

  Preferably, the school bag further includes a holding portion that can hold the lid, a tip portion that can be attached to and detached from the holding portion, and a connecting portion that is provided so as to connect the tip portion and the lid. . The connecting portion is sandwiched between the eyelet members while being inserted between the front surface and the back surface of the lid.

  For this reason, a connection part and a cover body can be fixed with an eyelet member. Then, the detachable member can be attached to the eyelet member in a state where the connecting portion and the lid are fixed by the eyelet member. Therefore, decorativeness can be improved with the detachable member while fixing the connecting portion and the lid with the eyelet member.

  In the above-mentioned school bag, the shaft portion preferably has a diameter larger than the diameter of the hole of the eyelet member. For this reason, when a shaft part contacts the inner peripheral surface of a hole of an eyelet member, it is controlled that a shaft part rotates in a hole of a eyelet member. Thereby, the position of the detachable member can be stabilized.

  As described above, according to the present invention, it is possible to provide a school bag including a detachable member that can be easily replaced with a simple structure and can improve decorativeness.

Moreover, the shape of the surface portion 4a of the detachable member 4 may constitute a pattern.

Next, the effect of the school bag according to the embodiment of the present invention will be described.
In the school bag according to the embodiment of the present invention, since the detachable member 4 is composed of the front surface portion 4a, the back surface portion 4b, and the shaft portion 4c, it has a simple structure. Further, the back surface portion 4b of the detachable member 4 has a diameter smaller than the diameter of the front surface portion 4a, can be elastically deformed, and at least one of the eyelet member 5 and the back surface S2 after passing through the hole H of the eyelet member 5. The heel can be engaged. For this reason, the back surface part 4b can pass the hole H of the eyelet member 5 easily. Therefore, the detachable member 4 can be easily attached to and removed from the hole H of the eyelet member 5. Further, by attaching the decorative member 4 to the hole H of the eyelet member 5, the decorativeness of the school bag can be improved.

  In the school bag according to the embodiment of the present invention, the connecting portion 13 is sandwiched between the eyelet members 5 in a state of being inserted between the front surface S1 and the back surface S2 of the lid body 3. And the lid 3 can be fixed. The detachable member 4 can be attached to the eyelet member 5 in a state where the connecting portion 13 and the lid 3 are fixed by the eyelet member 5. Therefore, the decorativeness can be improved with the detachable member 4 while fixing the connecting portion 13 and the lid 3 with the eyelet member 5.

  In the school bag according to the embodiment of the present invention, the shaft portion 4c has a diameter larger than the diameter of the hole H of the eyelet member 5, so that the shaft portion 4c contacts the inner peripheral surface of the hole H of the eyelet member 5. Accordingly, the rotation of the shaft portion 4c in the hole H of the eyelet member 5 is suppressed. Thereby, the position of the detachable member 4 can be stabilized.

  Although the embodiments of the present invention have been described above, the embodiments disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is indicated by the scope of the utility model registration request, and is intended to include all modifications within the meaning and scope equivalent to the scope of the utility model registration request.
