It has a slide fastener 20 of a book and a moving member 30 located at a closed side edge portion (upper edge portion in FIGS. 1 and 2) of the opening / closing member 10. The opening side edge portion (lower edge portion in FIGS. 1 and 2) of the opening / closing member 10 is connected to the main body 2 capable of storing an object inside. A shoulder belt 3 for carrying the backpack 1 is provided on the back surface of the main body 2.

Further, as shown in FIG. 3, the structure of the region A (near the right end of the moving member 30) in the backpack of FIG. 1 is such that the slide fastener 20 meshes a pair of fastener elements 21a and 21b with a pair of fastener elements 21a and 21b. -It is equipped with a slider 22 for separation. Although not shown in FIG. 3, the main body 2 is connected to the outside of the fastener element 20 in the meshed state (right side in FIG. 3) and the outside of the fastener element 21a arranged on the outside in the separated state. The opening / closing member 10 is connected to the inside of the fastener element 20 in the meshed state (left side in FIG. 3) and the inside of the fastener element 21b arranged inside in the separated state. Further, the structure near the left end of the moving member 30 in the backpack of FIG. 1 has a structure symmetrical to the structure of the region A shown in FIG.

Then, as shown in FIG. 3, the sliders 22 of the two slide fasteners 20 connected to the both side edges of the opening / closing member 10 are both attached to the moving member 30 (indicated by a broken line in FIG. 3) at the connecting portion 33. It is connected. Note that FIG. 3A is an embodiment in which the rear side puller 222 attached to the lower wing plate side of the slider 22 is connected to the moving member 30, and FIG. 3B is provided on the slider 22. It is an embodiment in which the lower wing protrusion plate 226 is connected to the moving member 30. The slider 22 used in FIG. 3A has a back side puller 222 attached to the lower wing plate side, and is commercially available for a so-called reversible type slide fastener. In FIG. 3A, the rear side puller 222 is connected to the moving member 30 in a state of facing upward, but the back side puller 222 may be in a state of facing downward or in a state of facing sideways. In particular, as will be described later, when a part of the opening / closing member 10 (closed side edge portion) is used as the moving member 30, the rear side puller 222 is connected to the closing side edge portion of the opening / closing member 10 in a state of facing sideways. It is preferable that it is. Further, the slider 22 used in FIG. 3B has a structure as shown in FIG. 4, for example, and has a lower wing protruding plate 226 protruding from the lower wing plate 224 in the direction of the shoulder opening 225. In addition, an embodiment in which a connecting portion 33 is formed on the back surface of the lower wing plate 224 of the slider 22 and connected to the moving member 30 is also conceivable. If the slider 22 is connected to the moving member 30 in this way, it is possible to compactly open and close the opening / closing area of the article (backpack) including those other than the above.

More specifically, first, as shown in FIG. 1, the moving member 30 is arranged at the closed end (upper end in FIG. 1) in a state where the opening / closing member 10 completely covers the opening / closing region 5. .. At this time, the two slide fasteners 20 connected to both side edges of the opening / closing member 10 are in a closed state in which the pair of fastener elements 21a and 21b are engaged with each other. From this state, when the moving member 30 is moved toward the opening side (downward in FIGS. 1 and 2), the slider 22 connected to the moving member 30 moves downward, whereby the pair of fastener elements 21a and 21b is separated. At this time, the fastener element 21a arranged on the outside in the separated state does not move because the main body 2 is connected to the outside.

On the other hand, since the opening / closing member 10 is connected to the inside of the fastener element 21b arranged inside in the separated state, the opening / closing member 10 is disconnected from the main body 2 and becomes a free state. However, since the moving member 30 located at the closed end of the opening / closing member 10 is connected to the slider 22, the opening / closing member 10 is not completely free. After all, as shown in FIG. 2, the opening / closing member 10 protrudes forward between the lower end of the opening / closing member 10 and the moving member 30 and loosens, so that it is less likely to get in the way.

On the contrary, as shown in FIG. 2, in a state where the opening / closing member 10 is completely opened and the opening / closing region 5 is not covered, the moving member 30 is arranged at the end portion on the opening side (lower end portion in FIG. 2). The two slide fasteners 20 are in a state where the pair of fastener elements 21a and 21b are separated and opened. From this state, when the moving member 30 is moved toward the closing side (upward in FIGS. 1 and 2), the slider 22 connected to the moving member 30 moves upward, whereby the pair of fastener elements 21a and 21b is meshed. At this time, the loose opening / closing member 10 is connected to and fixed to the main body 2 from below. Then, by moving the moving member 30 to the closed end (upper end in FIG. 1), the opening / closing member 10 completely covers the opening / closing region 5. In this way, the opening / closing area of the backpack (article) can be opened and closed compactly.

As shown in FIGS. 1 and 2, when the moving member 30 is moved in the closing side direction (upward in FIGS. 1 and 2), the moving member 30 moves from the closing side direction to the upper part on the front side of the main body 2. It is preferable that the eaves member 4 arranged so as to cover at least a part of the member 30 is provided. Since the eaves member 4 is provided on the main body 2, when the moving member 30 is moved in the closing side direction, the moving member 30 enters the back surface side of the eaves member 4, so that the moving member The gap between the upper part of the 30 and the main body 2 can be covered with the eaves member 4, and it is possible to prevent rain or the like from entering the inside of the main body 2.

The opening / closing member 10 may be made of a material that can be compactly loosened so as to be folded by moving the moving member 30 toward the opening side (lower side in FIGS. 1 and 2). , Knitted cloth, non-woven fabric, etc .; vinyl, fiber reinforced plastic sheet, multi-layer laminated body, etc., film; genuine leather, synthetic leather, etc. Among them, cloth or film is suitable from the viewpoint of flexibility.

If the fastener elements 21a and 21b of the above can be separated and the pair of fastener elements 21a and 21b can be meshed by moving the slider 22 in the closing side direction (upward in FIGS. 1 and 2). good. Since the two slide fasteners 20 are opened and closed at the same time by the movement of the moving member 30, it is preferable that the two slide fasteners 20 are connected to both side edges of the opening and closing member 10 in substantially parallel (including parallel).

The moving member 30 located at the closed side edge portion (upper edge portion in FIGS. 1 and 2) of the opening / closing member 10 is in the closing side direction (upper in FIGS. 1 and 2) or the opening side direction (in FIGS. 1 and 2). As long as the two sliders 22 connected to the two sliders 22 can be moved by moving them downward), they may be, for example, a part of the opening / closing member 10 (closed side edge), and the opening / closing member 10 may be closed. It may be installed as a separate body on the side edge. However, since the two sliders 22 are connected to both ends of the moving member 30, the moving member 30 is preferably a plate member 31 (plate-shaped object) extending between the two sliders 22. Further, it is preferable that the opening / closing member 10, the plate member 31, the slider 22, and the like are provided with a handle member 32 for moving the plate member 31. With the moving member 30 having such a configuration, the moving member 30 can be easily moved in the closing side direction or the opening side direction by holding the handle member 32. Since the slider 22 to which the moving member 30 is connected generally has a front side puller 221 for moving the slider 22 on the upper wing plate 223, by moving the two front side pullers 221. , The moving member 30 can be easily moved in the closing side direction or the opening side direction.

Further, as shown in FIGS. 1 and 2, both side edges of the moving member 30 (left and right side edges in FIGS. 1 and 2) are two slide fasteners 20 connected to both side edges of the opening / closing member 10. It is preferable that the fastener element 21a is arranged on the back surface side of the outer fastener element 21a. By doing so, when the moving member 30 is moved toward the opening side, the inner fastener element 21 easily protrudes toward the front side while the slide fastener 20 is separated, so that the opening / closing member 10 protrudes forward. It becomes easy to loosen in the state of being slackened.
