It is explanatory drawing which shows the state of the inside of the front surface and both side surfaces.

Hereinafter, embodiments of the rucksack according to the present invention will be described in detail with reference to the drawings.

In the figure, 1 is a rucksack main body, which is roughly composed of a backpack surface 2, a front surface 3, both side surfaces 4, 4, a bottom surface 5, and an upper surface 6.

1 to 8 mainly explain the back support surface 2. The backrest surface 2 is a portion that hits the back when the rucksack 1 is carried on the back, and includes backpack belts 10 and 10. The backrest belts 10 and 10 are formed in a shape curved outward from the upper side to the lower side, and the upper end portions thereof are sewn to the upper end portions 28, 28 of the back support surface 2. Further, the backpack belts 10 and 10 have a thickness of 10 mm or less and a width of 50 mm or less. A cushioning material is contained inside the backpack belts 10 and 10, and there are cases where only a soft material is used and cases where a soft material and a hard material are used twice.

By reducing the thickness of the backpack belts 10 and 10 to 10 mm or less and using the material inside the backpack belts 10 and 10 as a cushioning material, the load on the shoulder of the rucksack 1 is applied even when using the carrying strap. It is reduced, and it becomes easier to hang the backpack belts 10 and 10 on the shoulder with respect to the thickness of the portion of the carrying strap that is applied to the shoulder. Further, by setting the width of the backpack belts 10 and 10 of the rucksack 1 to 50 mm or less, the backpack belts 10 and 10 come into contact with the clavicle when carried on the back, and slipping from the shoulder can be prevented. Conventional backpack belts are generally 50 mm or more, and if they are wide, the backpack belt will come to the outside of the collarbone when carried on the back, and depending on the physique, it may slip off the shoulders. By forming the backpack belts 10 and 10 in the above configuration, it is possible to prevent slipping from the shoulders, and it is possible to realize ease of carrying and comfort. The width of the backpack belts 10 and 10 is preferably about 45 mm to 50 mm.

FIG. 4 shows the movements of the backpack belts 10 and 10 when the chest belt 15 is not worn, and FIG. 5 shows the movements of the backpack belts 10 and 10 when the chest belt 15 is worn. When the chest belt 15 is attached near the upper end, the backpack belt 10 is shown. As shown in FIG. 5, No. 10 is fixed at the upper part and does not slip off the shoulder, while the lower part of the rucksack 1 is not fixed to the body, so that the rucksack 1 can be comfortably carried on the back without pressure on the chest. Can be done. It is also possible to insert a hand between the back carrying surface 2 and the back.

A first pocket 23 that opens and closes with a fastener 21 is formed below the back carrying surface 2. The fastener 21 is formed in an inverted U shape in the illustrated example, and has two sliders 22 and 22. By having the two sliders 22 and 22, it is possible to open and close from either the left or right while carrying the rucksack on the back. Since the first pocket is usually in contact with the back when carrying it, it is effective for crime prevention by putting valuables such as a wallet, and it is safe to feel that it is stored in the pocket. is there.

Further, in the figure, the fasteners 24 and 24 are formed on the back support surface 2, but may be provided on both side surfaces 4 and 4.

A second pocket 29 is formed directly below the fixing surfaces 28, 28 between the back support surface 2 and the upper ends of the backrest belts 10, 10. The second pocket 29 is formed so as to extend to the lower end of the rucksack 1 main body, and a long object such as an umbrella can be put in while carrying the rucksack 1. Further, a tape 31 having a removable buckle 30 is housed in the second pocket 29, and both ends of the tape 31 are sewn to the rucksack 1 main body in the second pocket 29. .. For example, when it is desired to attach the rucksack 1 to a fence, a pole, a headrest of a car, or the like, the rucksack 1 can be hung on them by taking out the tape 31 from the pocket 29 and separating and attaching the buckle 30. The backpack belts 10 and 10 can be stored in the second pocket 29 in a state where the buckles 13 and 13 are separated.

At the lower end of the back support surface 2, the inside is covered with a vinyl material, and a third pocket 33 that opens and closes laterally with a fastener 32 is formed. A slush pocket 35 for accommodating the pull tab 34 is provided at the left end of the fastener 32, which is effective in preventing noise generated when the pull tab shakes and in crime prevention by hiding the pull tab. In the illustrated example, the pull tab 34 is housed in the slush pocket 35. It is convenient to put wet or dirty items in the pocket 33 while carrying the rucksack 1. Since the inside is made of vinyl material, other parts will not get wet and it is easy to clean even if it gets dirty.

A fastener 37 for pulling out the folded bag-shaped storage portion 36 is formed on the peripheral edge of the lower end portion of the rucksack 1 main body. By opening the fastener 37 and extending the storage portion 36 downward, the storage portion 36 is expanded as shown in FIG. 8, and as a result, the total length of the rucksack 1 main body is extended to become a two-layer rucksack with two upper and lower chambers. .. The storage unit 36 is provided with a fastener 38, and an object can be stored in the storage unit 36. For example, it is suitable for storing a jacket, a carrying strap, or the like. In the illustrated example, the fastener 38 includes two sliders 39 and 39, and can be opened and closed by either the left or right hand. Note that FIG. 8 shows the development of the front surface and the side surface of the storage unit 36.

FIG. 10 is a right side view of the rucksack 1, and lower bulging fourth pockets 40, 40 are formed below the side surfaces 4, 4. A D ring 46 sewn on the main body of the rucksack 1 is provided in the fourth pockets 40 and 40, which is suitable for storing a key chain or the like.
