Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shoulder belt upper end fitting for a backpack such as a school bag or rucksack.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, a shoulder belt upper end fitting for a backpack such as a school bag or a rucksack is formed by cutting a substantially central portion of a bent portion of a connecting plate 4 which is formed by folding a metal plate in two. Two insertion parts 31, 31 are provided, and a stop hole 32 is provided below each of the insertion parts 31, 31, and a space 33 formed on the end sides of both the insertion parts 31, 31 facing each other is approximately Ω. There is a suspension ring 19 having a shape in which a leg portion is rotatably attached, and further substantially triangular attachment rings 3 and 3 are rotatably attached to both ends of both insertion portions 31 and 31, respectively.

As shown in FIG. 6, the shoulder strap upper end fitting of the backpack bag thus configured is slightly lowered from the top or the top of the backrest portion 6 of the backpack 5 such as a school bag. It was attached to the position, and the upper ends of the shoulder belts 1 and 1 were attached to the attachment rings 3 and 3, respectively.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional shoulder belt upper end fitting for a backpack, the attachment rings 3, 3 attached to both ends of the insertion portions 31, 31 of the connecting plate 4 rotate in the user's back direction, and the attachment ring 3, During use, the shoulder straps 1 and 1 attached to 3 are gradually displaced from the shoulders due to the weight of the backpack bag 5, and the backpack bag 5 is tilted rearward away from the user's back as shown in FIG. Therefore, the center of gravity of the backpack bag 5 is separated from the user's back, and the backpack bag 5 becomes difficult to carry and feels heavy.

Further, in order to adjust the lengths of the shoulder straps 1 and 1 of the backpack 5, the connection positions of the shoulder straps 1 and 1 and the lower adjustment belt (not shown) are shifted, The shoulder belt upper end fittings of the backpack cannot move the mounting positions of the shoulder belts 1 and 1, so that it is not enough to fit the user's physique, and the user feels pressure or fatigue. Etc. had the problem of giving.

Therefore, according to the present invention, the shoulder straps 1 and 1 do not shift from the shoulders due to the weight of the backpack bag 5 during use, and the backrest portion 6 of the backpack bag 5 is in close contact with the user's back, and the backpack bag 5 is attached. The center of gravity of the shoulder bag 1 does not move away from the user's back, the shoulder bag 5 does not feel heavy, and the shoulder belts 1, 1 are attached so that the shoulder belts 1, 1 are moved when the shoulder bag 5 is carried on the back. An object of the present invention is to provide a shoulder strap upper end fitting for a backpack bag which allows the user to fit 1 into the physical constitution of the user and does not give the user a feeling of pressure or fatigue.

[0007]

[Means for Solving the Problems]

 Therefore, in the shoulder strap upper end attachment of the backpack according to the present invention, the attachment rings 3 and 3 are integrally provided above the connecting plates 4 and 4, respectively. Further, the shoulder strap upper end fitting of the backpack according to the present invention is provided with teeth 4a and 4a on the opposite side surfaces of the connecting plates 4 and 4, respectively, and the teeth 4a and 4a are meshed with each other to form the connecting plate 4, 4 is attached to the back support portion 6 of the carrying bag 5 so as to be swingable, and the connecting plates 4 and 4 are each provided with an inward elastic force.

[0008]

[Action]

 The present invention, having the above-mentioned means, has the following operation. First, since the shoulder belts 1 and 1 attached to the attachment rings 3 and 3 are in a state of being directed upward from the bag body, when carrying a backpack 5 having such a shoulder belt upper end mounting tool on its back, the backpack 5 is The user always tries to keep the backpack 5 in close contact with the user's back by pulling it diagonally upward.

Further, the mounting positions of the shoulder belts on the mounting rings 3 and 3 are moved in the left and right directions by the same width within the swing width of the connecting plates 4 and 4 according to the physical constitution of the user. In addition, the mounting rings 3, 3 can be maintained in a state corresponding to the physical constitution of the user by the inward elastic force applied to the connecting plates 4, 4.

【Example】

 The structure of the shoulder belt upper end fitting of the backpack according to the present invention will be described below with reference to the drawings shown as an embodiment. FIG. 1 is a perspective view of a school bag equipped with the shoulder strap upper end fitting of the present invention, as viewed from the back rest side. Reference numeral 1 denotes a shoulder belt, the upper end of the shoulder belt 1 is attached to an upper end fitting 2, and the lower end of the shoulder belt 1 is attached to a lower end fitting (not shown).

As shown in FIG. 2, the upper end fixture 2 has mounting rings 3 and 3 integrally provided in the upper direction of the connecting plates 4 and 4, respectively. The mounting rings 3 and 3 are not particularly limited as long as they are provided in the upper direction of the connecting plates 4 and 4. However, the mounting rings 3 and 3 are located right above the backrest portion 6 of the backpack bag 5 to the shoulder belt 1 side. It is preferably tilted by about 20 to 30 °.

Further, the upper end fitting 2 is provided with teeth 4a and 4a on the opposite side surfaces of the connecting plates 4 and 4, respectively, and these connecting teeth 4a and 4a are meshed with each other to connect the connecting plates 4 and 4 to the back support portion. 6 are swingably mounted, and the connecting plates 4 and 4 are each provided with an inward elastic force. In the embodiment, in order to swingably attach the connecting plate 4 to the back support portion 6, as shown in FIGS. 2 and 3, the connecting plate 4 is sandwiched between the upper and lower covering plates 7a and 7b, and the connecting plate 4 is inserted. The slide body 9 provided on the lower cover plate 7b is fitted into the slide hole 8 formed in the above, and the stopper body 11 provided on the lower cover plate 7b is pivotally supported in the shaft hole 10 provided at the lower end of the connecting plate 4. Furthermore, in order to apply an inward elasticity to the connecting plates 4, a spring 12 for pressing the outer surface 4b of each connecting plate 4 inward is attached between the upper and lower covering plates 7a, 7b. The spring 12 has a substantially U shape, the outer body 12a is supported by the support portion 13 and the support body 14 provided on the lower cover plate 7b, and the inner body 12b abuts the outer surface 4b of the connecting plate 4. I am trying.

Reference numeral 15 is a pressing plate for pressing the cloth 16 (see FIG. 1) on the upper cover plate 7a. Reference numeral 17 is a protector attached to both ends of the pressing plate 15, and is for preventing the cloth 16 pressed against the upper cover plate 7a by the pressing plate 15 from being damaged. Reference numeral 18 denotes a name card case, which is locked to the upper cover plate 7a from above the cloth 16.

Further, 19 is a suspension ring for suspending the backpack 5 when not in use, and is provided integrally with the lower cover plate 7b. It is preferable that the suspension ring 19 is also tilted from the back support portion 6 toward the shoulder belt 1 side by about 20 to 30 ° similarly to the attachment rings 3 and 3. Then, the upper end fitting 2 allows the rivet 21 to penetrate from the rivet hole 20a provided at the peripheral end of the upper cover plate 7a to the rivet hole 20b provided at the peripheral end of the lower cover plate 7b to carry the backpack. 5 is riveted to a stop plate 22 attached to the back side of the back support part 6 of FIG.
