DETAILED DESCRIPTION OF THE INVENTION

[0016] As shown in FIG. 1 to FIG. 4, the first preferred embodiment of the present invention, a backpack for large objects 1, is revealed. Said backpack for large objects 1 includes a main body 10, two straps 20, a first wing 30, a second wing 40, and an extended piece 50, wherein the main body 10 has a holding space therein. Two ends of each of the straps 20 are respectively connected to the rear of the main body 10 so that the two straps can be used as shoulder straps.

[0017] Two opposite sides of the main body 10 are respectively connected to the first wing 30 and the second wing 40. The first wing 30 and the second wing 40 can be connected to each other detachably, and the first wing 30, the second wing 40, and the main body 10 enclose and form a first holding space B. the extended piece 50 is connected to the main body 10, and is provided close to a bottom opening P1 or a top opening P2 of the first holding space B.

[0018] In this embodiment, the first wing 30 and the second wing 40 are connected to each other through two fasteners 60 and two belts 62 on the front side 10b of the main body 10. Each of the belts 62 is provided between the first wing 30 and the second wing 40, and the length of each of the belts 62 is adjustable. Therefore, the user can adjust the lengths of the belts 62 according to the size of the objects, and thereby change the volume of the first holding space B to meet the user's needs. In other embodiments, the number of the fasteners and the belts can be one or more than two correspondingly, and is not limited to be two.

[0019] As shown in FIG. 2, the first wing 30 and the second wing 40 respectively has a containing bag 64; the containing bags 64 are respectively provided on the interior faces of the first wing 30 and the second wing 40 which face to the first holding space B. Thus, the first wing 30 and the second wing 40 have not only the function of forming the first holding space B with the main body 10, but also the function of storage. Practically, the containing bag 64 can be only provided on either the first wing 30 or the second wing 40, and is not limited to be provided on both the first wing 30 and the second wing 40.

[0020] In this embodiment, the extended piece 50 has a first side 50a and a second side 50b, wherein the first side 50a includes a first connector 52, and the second side 50b is connected to a bottom 10c of the main body 10. The first side 50a of the extended piece 50 is detachably connected to the main body 10 by the first connector 52. Furthermore, the main body 10 includes a plurality of joint pieces 12 which are disposed at intervals on the front side 10b of the main body 10, wherein the joint pieces are arranged from the part close to the top 10d of the main body 10 to the part away from the top 10d of the main body 10. The first connector 52 is detachably connected to one of the joint pieces 12. Therefore, when the first wing 30 and the second wing 40 are connected to each other to form the first holding space B with the main body 10, and moreover, the first connector 52 of the extended piece 50 is connected to the joint piece 12, the extended piece 50 covers the bottom opening P1 of the first holding space B. In this way, when a user puts an object S into the first holding space B as shown in FIG. 4, the extended piece 50 can hold the object at the bottom opening P1 of the first holding space B. Additionally, because the top opening P2 of the first holding space B communicates with the outside, if the object to be carried is large, one part of the large object S can be located inside the first holding space B, while the other part is exposed to the outside through the top opening P2. Furthermore, the user can select a suitable joint piece 12 according to the size of the object to be connected to the first connector 52 for adjusting the volume of the first holding space B.

[0021] In addition, depending on the needs, users can connect the first connector 52 of the extended piece 50 with the joint piece 12 first, and then connect the first wing 30 with the second wing 40, which makes the first wing 30 and the second wing 40 exposed as illustrated in FIG. 1. Or alternatively, as shown in FIG. 4, users can connect the first wing 30 with the second wing 40 first, and next, connect the first connector 52 of the extended piece 50 with the joint piece 12, which makes the extended piece 50 exposed as well as cover the fasteners 60 of the first wing 30 and the second wing 40 to avoid the fasteners 60 from being accidentally detached which causes the objects within the first holding space B to drop off or be lost.

[0022] As shown in FIG. 5 to FIG. 8, the second preferred embodiment of the present invention, a backpack for large objects 2, has similar structure with the backpack for large objects 1, which is not described herein again. The difference is, in this embodiment, an extended piece 70 includes a bag 72 hanging from the main body 10. In addition, the extended piece 70 is provided near the bottom opening P1 of the first holding space B. The bag 72 has an opening 72a close to the top of the bag 72, wherein the opening 72a communicates with the interior of the bag 72. The first holding space B is extended to the interior of the bag 72 through the opening 72a to form a second holding space, wherein the volume of the second holding space is greater than the volume of the first holding space B. In this way, when a large object S is placed in the second holding space, the bottom of the object S can be contained in the interior of the bag 72, while a part of the object S is located in the first holding space B through the opening 72a. Furthermore, because the top opening P2 of the first holding space B communicates with the outside, a part of the object S can pass through the top opening P2 and be exposed to the outside. By the support from the bag 72, the first wing 30, the second wing 40, and the main body 10, the object S can be contained safely in the second holding space.

[0023] In this embodiment, the second side 70a of the extended piece 70 includes a second connector 74, wherein the first connector 52 and the second connector 74 are provided on two opposite sides of the extended piece 70 respectively. The first connector 52, as described in the first embodiment, is detachably connected to the front side 10b of the main body 10. The extended piece 70 is detachably connected to the bottom 10c of the main body 10 through the second connector 74. In this embodiment, the second connectors 74 are two connection buckles. In another preferred embodiment, the second side 70a of the extended piece 70 can be connected to the top 10d of the main body 10 through the second connector 74 so as to cover the top opening P2 of the first holding space B. Additionally, depending on the needs, the user can put the extended piece 70 on the first wing 30 and the second wing 40 as shown in FIG. 7. In this way, it's convenient for the user to restore the object in or take the object out from the bag 72. Or alternatively, the user can put the extended piece 70 behind the first wing 30 and the second wing 40 as shown in FIG. 8.

[0024] The embodiments described above are only preferred embodiments of the present invention. All equivalent structures which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
