Description

  This invention relates to a rucksack, more specifically to a rucksack that can be easily opened and closed, can be used in a large or small size by increasing or decreasing the amount of objects to be put in, and also reliably prevents the inflow of raindrops.

Japanese Laid-Open Utility Model Publication No. 6-75224 discloses this type of rucksack. According to the publication, at least an upper surface 2 and a front portion 3 of a main container 1 are formed of one piece of cloth, and an entrance 7 which is open except for left and right side edges between the upper surface and the front portion. Describes a rucksack in which the lid 8 is formed to be openable and closable with a fastener.

  However, the opening and closing of the lid with the zipper in the U-shape has to be held with one hand and the pulling device must be operated with the other hand. There is also a problem that raindrops flow into the rucksack from the fastener portion. Also, there is a problem that a rucksack cannot be reduced in size even if the size of the rucksack continues to be kept constant irrespective of the increase or decrease in the amount to be put.

  In the present invention, the main accommodating portion of the rucksack is extended upward to form a flat, wide-mouthed extended end, a flat fastener for opening and closing is attached to the inner surface of the extended end, and a fastening band is attached to the outer surface on the back side. The extension end is turned one or more times inwardly around the flat fastener according to the amount of the contents in the rucksack, and the both ends are folded inward to close the tightening band. This is intended to solve such a problem.

  As described above, the present invention extends the rucksack upward and opens and closes the extended end by contacting and separating the flat fastener, so that it can be easily and easily opened and closed regardless of age. It is possible to change the size of the rucksack by turning the extended end one or more times around the flat fastener, depending on the increase or decrease of the contents. As a result, there is an effect that no inflow of raindrops occurs.

  The present invention extends upward with the main accommodating portion of the rucksack being open, flattens the extended end, attaches a flat fastener for opening and closing to the inner surface of the extended end, and both ends of the outer surface on the back side A fastening band is attached to the flat fastener, and the extended end is wound one or more times inward with the flat fastener as an axis, and the both ends are folded inward to tighten the band, depending on the amount of contents in the rucksack. By attaching and detaching the flat fastener, the extension end for opening and closing the object can be easily opened and closed, and the rucksack can be used big or small according to the storage capacity, and the raindrops can be prevented from entering without having to cover with a canopy Can be done.

  The main housing portion 2 of the rucksack 1 formed of waterproof fabric is extended upward while the main housing portion 2 is open, and the extension end 2a is flattened. The male and female flat fasteners 3a, 3b are provided on the inner surface of the extension end 2a. Attachment, male and female fastening bands 4a, 4b are attached to both ends of the outer surface on the back side of the extension end 2a. 5a, 5b, 5c are pockets on both sides and the front, and 6 is a backpack belt.

  In the rucksack 1 of the present invention, the fastening bands 4a, 4b are removed, the flat fasteners 3a, 3b are disengaged, the extended end 2a is opened, and an object is put into the main accommodating portion 2 from the opened extended end 2a. After that, as shown in FIG. 2 (a), the planar fasteners 3a and 3b are closed together and closed. However, depending on the large amount of storage, for example, as shown in FIG. Is packed once or twice around the flat fasteners 3a and 3b which are aligned and closed as shown in FIGS. 2 (b) to 2 (d), and then folded inward at both ends to tighten the tightening band. 4a and 4b are fastened. As shown in FIG. 3 (b), when the amount of storage is small, the extended end 2a is folded three times and four times inward, and the both ends are folded inward to tighten the tightening bands 4a, 4b. To conclude. In any case, the opening closed by the flat fastener is wound and folded so as to cover the inside, so that the infiltration of raindrops can be reliably prevented. The planar fasteners 3a and 3b may be attached with a gap between each of the opposed middles to provide a finger insertion gap for opening and closing.

  As described above, the rucksack of the present invention can be easily and easily opened and closed, and can be selectively used in accordance with the amount of storage, and can reliably prevent the inflow of raindrops. It can be widely and conveniently used.

Perspective view showing the extended end opened (A) is a partial perspective view showing a state where the flat fastener is hung and the mouth is closed, (b) is a perspective view showing a state where the flat fastener is partially closed and folded once, and (c) is a further two views. (D) is a perspective view of a state where both ends are folded inward and a tightening band is tightened. (A) is a perspective view showing a closed state when the storage amount is large, and (b) is a perspective view when the rucksack is used small when the storage amount is small.
