Description of Connection State Between Main Body Portion 10 and Strap 20

As described above, in the bag 1 of the present embodiment, the first hook member 11 and the first annular portion 12 are respectively provided at both end portions in the longitudinal direction on an upper side of the main body portion 10, and the second annular portion 21 and the second hook member 22 are respectively provided at both end portions of the strap 20. Therefore, in the bag 1 of the present embodiment, the connection state between the main body portion 10 and the strap 20 can be selected from among a plurality of connection states and can be easily switched for use. Hereinafter, the first to third connection states of the bag 1 will be described.

First, in the first connection state, as illustrated in FIGS. 1 to 3, the first hook member 11 of the main body portion 10 is engaged with the second annular portion 21 at one end portion of the strap 20, and the first annular portion 12 of the main body portion 10 is engaged with the second hook member 22 at the other end portion of the strap 20. In the bag 1 in the first connection state, both end portions of the strap 20 are connected to both end portions in the longitudinal direction on the upper side of the bag 1, so that the main body portion 10 can be stably supported by the strap 20. For example, the bag 1 in the first connection state can be used like a handbag in which the strap 20 is supported by a palm or a forearm in addition to a general shoulder bag in which the strap 20 is hung on a shoulder.

Next, in the second connection state, as illustrated in FIG. 4, the first hook member 11 of the main body portion 10 is engaged with the second annular portion 21 of one end portion of the strap 20, and the second hook member 22 of the other end portion of the strap 20 is similarly engaged with the second annular portion 21 of one end portion of the strap 20. In the bag 1 in the second connection state, the main body portion 10 is in a state of being supported by the strap 20 only by the first hook member 11 at one end portion. Therefore, the main body portion 10 is supported in an inclined state in which the end portion on a side where the first hook member 11 is provided is positioned at the uppermost position and the end portion on a side where the first annular portion 12 is provided is positioned at the lowermost position. The bag 1 in the second connection state can be used like a shoulder bag or a handbag similarly to the first connection state, but an appearance impression can be greatly changed from that in the first connection state.

Finally, in the third connection state, as illustrated in FIG. 5, the first hook member 11 of the main body portion 10 is engaged with the first annular portion 12. The third connection state is a connection state in which both end portions of the main body portion 10 are connected to each other without using the strap 20. The bag 1 in the third connection state is in a state in which both end portions of the arc of the main body portion 10 having a substantially semicircular shape in the front view are lifted and engaged with each other, so that the main body portion 10 has a shape close to a circular shape in the front view. In the bag 1 of the present embodiment, the main body portion 10 is made of a material having high flexibility so as not to be deteriorated or damaged even if the deformation due to the third connection state is maintained for a long time. The bag 1 in the third connection state can be used like a handbag with the vicinities of both end portions of the arc of the main body portion 10 as a handle.

Effects of Present Embodiment

As described above in detail, in the bag 1 of the present embodiment, the main body portion 10 has the first hook member 11 attached to an upper side of the main body portion 10 and the first annular portion 12 similarly provided at a position substantially opposite to the first hook member 11 on the upper side of the main body portion 10, and the strap 20 has the second annular portion 21 that is provided at one end portion and is engageable with at least the first hook member 11 and the second hook member that is attached to the other end portion and is engageable with at least the first annular portion 12.

As described above, since the hook member and the annular portion that can be engaged with each other are provided in each of the main body portion 10 and the strap 20, it is possible to freely select a hook member and an annular portion to be engaged from among the plurality of hook members and the plurality of annular portions. Therefore, the connection state between the main body portion 10 and the strap 20 can be selected from among the plurality of connection states and can be easily changed.

In particular, the bag 1 of the present embodiment is configured to be able to switch between the first to third connection states. In the first connection state, the first hook member 11 of the main body portion 10 is engaged with the second annular portion 21 at one end portion of the strap 20, and the first annular portion 12 of the main body portion 10 is engaged with the second hook member 22 at the other end portion of the strap 20. Further, in the second connection state, the first hook member 11 of the main body portion 10 is engaged with the second annular portion 21 of one end portion of the strap 20, and the second hook member 22 of the other end portion of the strap 20 is similarly engaged with the second annular portion 21 of one end portion of the strap 20. In addition, in the third connection state, the first hook member 11 of the main body portion 10 and the first annular portion 12 are engaged with each other without using the strap 20.

As described above, since the first to third connection states in which a use method and an appearance of the bag 1 can be greatly changed can be easily switched, the user can select the use method and the appearance of the bag 1 according to a situation and a mood at that time.

In addition, since the main body portion 10 of the bag 1 is made of a material having a degree of flexibility that allows the third connection state to be maintained, even if the deformation due to the third connection state is maintained for a long time, it is possible to suppress occurrence of the deterioration or damage in the main body portion 10.

In particular, in the bag 1 of the present embodiment, the main body portion 10 has a substantially semicircular shape in the front view, the first hook member 11 is attached to the vicinity of one end portion of the arc, and the first annular portion 12 is provided in the vicinity of the other end portion of the arc. Therefore, in the third connection state in which the first hook member 11 of the main body portion 10 and the first annular portion 12 are engaged with each other, it is possible to obtain a beautiful appearance in which the main body portion 10 has a substantially circular shape in the front view.

Note that the above-described embodiments are examples for describing the present invention, and are not intended to limit the present invention only to the embodiments.

For example, in the embodiments, a part such as the slide adjuster is used as the length adjusting mechanism 23 of the strap 20, but it is also possible to provide a plurality of engagement members such as snap buttons instead of the slide adjuster and adjust the length of the strap 20 by changing an engagement position.

In addition, the present invention can be implemented in various forms without departing from the gist of the present invention.
