Opening. A third opening is formed between the edge of the second bag 16 and the edge of the third bag 18 to communicate with the inside of the bag body 10, and the second bag cloth 16 and the third bag cloth 18 have the bottom portion A connecting end 12a of the flap portion 12 is connected to the body portion 20. A fourth opening is formed between the edge of the bag portion 12 and the edge of the bag body 20, and the fourth opening communicates with the inside of the bag body 10 and surrounds the first, second, and third bag cloths 14, 16, 18 periphery. The bag body portion 20 is provided with two side pockets 22, which are respectively located on both sides of the flap portion 12.

The first zipper 24 and the second zipper 26 are disposed on the bag body 10 and are respectively located at the periphery of the first opening and the second opening, and respectively close the first opening and the second opening. The first zipper 24 and the second zipper 26 are respectively inclined downward from the two sides of the first woven fabric 14 in the direction of the center, and one end 242 of the first zipper 24 is opposite to one end 262 of the second zipper 26. adjacent. The first zipper 24 and the second zipper 26 each have a slider 244, 264.

The third zipper 28 is disposed on the bag body 10 and located at a periphery of the third opening. The third zipper 28 includes a first chain segment 282, a second chain segment 284, and a slider 286. The first segment 282 is located between the second segment 284 and the first bag 14 and the first segment 282 is adjacent to the end 242 of the first zipper 24 and the end 262 of the second zipper 26, the slider The 286 is moved along the first segment 282 and the second segment 284 to open or close the third opening. Thereby, the first, second, and third zippers 24, 26, 28 form a Y-shaped zipper set.

The fourth zipper 30 is disposed on the bag body 10 and is located at a periphery of the fourth opening to close the fourth opening. The fourth zipper 30 includes two sliders 302, and the two ends of the fourth zipper 30 are respectively located at the On both sides of the connecting end 12a, the two sliders 302 can respectively open the fourth opening in different directions, and the user can flip the flap portion 12 (refer to FIG. 6), thereby inserting a large item into the bag body.

The second bag cloth 16 and the third bag cloth 18 are respectively provided with two first adhesive pads 42 at the end portion 242 of the first zipper 24 and the end portion 262 of the second zipper 26, and the third zipper is provided. A first segment 282 of 28 is located between the two first mats 42.

The first cover cloth 32 is connected to the first cloth cloth 14. In the embodiment, the first cover cloth 32 includes a tongue portion 322 and a base portion 324. The inner surface of the tongue portion 322 is provided with a second surface. The base portion 324 is connected to the inner side of the first bag cloth 14, and may be connected to the outer side of the first bag cloth 14 in practice. The first cover cloth 32 can be changed in an unfolded state and a folded state. In the unfolded state (refer to FIG. 1 and FIG. 2), the tongue portion 322 is from the first zipper 24 and the second zipper. The sliders 244, 264 of the 26 protrude from the outside of the bag body 10, and the second adhesive tape 44 is detachably bonded to the two first adhesive pads 42. Thereby, the tab portion 322 of the first cover cloth 32 covers the first chain segment 282 of the third zipper 28 and the slider 286 of the third zipper 28, so that the slider 286 is hidden to achieve anti-theft. The function is to prevent the user from pulling the slider 286 of the third zipper 28 from the back of the user when the user is carrying the backpack.

In order to enable the tongue portion 322 to be received inside the bag body 10, the backpack further includes a third adhesive tape 46 disposed on the inner side of the first bag cloth 14. In the embodiment, the third adhesive tape 46 is disposed on the base portion 324 of the first cover cloth 32 (refer to FIG. 3 ), and is disposed on the inner side of the first cloth cloth 14 through the base portion 324 . 4 and FIG. 5, when the first cover cloth 32 is in the folded state, the first cover cloth 32 is stored in the bag body 10, and the tongue portion 322 is folded back to make the second adhesive felt. 44 is bonded to the third adhesive tape 46. The slider 244 of the first zipper 24 and the slider 264 of the second zipper 26 can be respectively pulled to the respective ends 242, 262 of the first zipper 24 and the second zipper 26.

A first strap 48 is disposed on the outer surface of the tab portion 322 of the first cover cloth 32. The two ends of the first strap 48 are coupled to the tab portion 322. The first strap 48 is for the user to pull. The first cover cloth 32 separates the second adhesive pad 44 from the two first adhesive pads 42 and drives the two pull ends 244, 264 from bottom to top to quickly turn the first cover cloth 14 From (Figure 3 reference).

The first bag cloth 14 is provided with a second drawing tape 50. The two ends of the second drawing tape 50 are coupled to the outer surface of the first bag cloth 14. The second drawing tape 50 is also for the user to pull the first bag. The bag cloth 14 is used to quickly flip the first bag cloth 14 from bottom to top. In particular, when the first cover cloth 32 is in the folded state (refer to FIG. 5), the user aims to quickly flip the first cloth cloth 14 by the second pull tape 50.

The fastener group 34 includes two fasteners that are detachably fastened. The two fasteners are respectively a female snap 36 and a male snap 38. The female snap 36 is coupled to the first fabric 14 and the female snap 36 The opposite sides have two notches 362 communicating with the inside thereof, and the two notches 362 are shielded by the second strap 50 (refer to FIG. 5). The male buckle 38 is coupled to the slider 286 of the third zipper 28 via a connecting strap 40. The male buckle 38 has two hooks 382 located in the two notches 362. The two notches 362 and the hooks 382 form an unfastened portion of the fastener set 34. The release engagement portion is separated from the female buckle 36 by the user after being pressed by the user. After the male buckle 38 is fastened to the female buckle 36, the connecting tape 40 is located outside the first covering cloth 32 and covers the first covering cloth 32 and the first pulling belt 48, thereby adding another weight to the backpack. It is not easy for a person with a heart to flip the first cover 32.

In order to make the opening of the flap portion 12 more convenient, in addition to directly pulling the two sliders 302 of the fourth zipper 30, the backpack of the embodiment further comprises a second cover cloth 52, and one end of the second cover cloth 52 A second adhesive pad 54 is disposed on the second cover cloth 52 in a position of the inner side of the first bag cloth 14 relative to the connecting end 12a. The second cover cloth 52 is in an unfolded state and a folded state. The state of the second cover 52 extends from the two sliders 302 of the fourth zipper 30 to the bag body 10 (refer to FIG. 8). In the folded state, the second cover is changed. The cloth 52 abuts against the inside of the first bag 14 (refer to Fig. 6).

The bag body portion 20 is provided with a fifth adhesive tape 56 at the top position for bonding the second cover cloth 52 to the fourth adhesive tape 54 in the unfolded state (refer to FIG. 7 and FIG. 8); the first bag cloth 14 Further, a sixth adhesive tape 58 is disposed on the inner side for bonding the second cover cloth 52 to the fourth adhesive tape 54 in the folded state.

When the user wants to open the flap portion 12, the top of the pocket portion 20 and the second flap 52 can be respectively pulled in opposite directions, that is, the two sliders 302 can be moved downward to quickly The flap portion 12 is opened. The second cover cloth 52 and the top of the body portion 20 are respectively coupled with a third pull belt 60 and a fourth pull belt 62, so that the user can more easily apply force when turning the cover portion 12.

In summary, the backpack of the present invention can achieve a double anti-theft effect by the design of the first cover cloth 32 and the fastener set 34, and after the female buckle 36 and the male buckle 38 are unlocked, the user pulls the first The cover 32 can easily open the bag body 10. The foldable design of the first drape 32 allows the user to select whether or not to cover the first segment of the third zipper 28.
