Hereinafter, a mounting structure for a backpack for a school bag according to the present invention will be described with reference to the drawings.
1 to 4 show an embodiment of a backpack belt mounting structure for a school bag according to the present invention, respectively. FIGS. 1 and 2 are a side view and a perspective view of a lower end mounting tool for a lower belt of the school bag. FIG. 3 shows a front view of a pair of left and right shoulder belts of the school bag, and FIG. 4 shows a front view of an upper end fixture for attaching the upper ends of the upper belts of the pair of left and right shoulder belts. ing.

  As shown in FIGS. 5 and 6, the school bag 11 includes a school bag body 12 whose upper opening is opened and closed by a lid body 19, and a pair of left and right shoulder belts 15 fixed to the back plate 13 of the school bag body 12. ing. The backpack 15 includes a pair of left and right symmetrical upper belts 21 attached to the upper center side of the back plate portion 13 of the school bag body 12, and a pair of left and right symmetrical lower belts 23 attached to the bottom 14 side of the school bag body 12. The upper belt 21 and the lower belt 23 are connected by a connecting tool 25 such as a vision and a buckle, respectively.

  An upper end 21 a of the upper belt 21 is fixed to an upper end fixture 17 made of a mounting bracket fixed to the upper center of the back plate portion 13, and a lower end fixture 26 is formed on a lower end 23 a of the lower belt 23. Yes. The upper end fixture 17 has a plate body 41 and a wire-like connection member 42, and the plate body 41 is bent in the vertical direction to form an insertion portion 43 for the wire-like connection member 42. Note that an outward bent portion 44 a of the retaining ring 44 is inserted into the insertion portion 43. Reference numeral 45 denotes a notch formed at the center of the insertion portion 43.

  An inwardly bent portion 42a is formed in the upper part of the connecting member 42 so as to be refracted inwardly. A substantially W-shaped portion 42b is formed in the lower portion of the connecting member 42, and the center of the W-shaped portion 42b. A substantially trapezoidal portion 42c is formed to protrude upward. The inwardly bent portion 42a of the connecting member 42 is inserted into the insertion portion 43 of the plate body 41, and the upper ends of the pair of left and right upper belts 21 of the shoulder belt 15 are respectively connected to the upper and lower inclined portions of the substantially W-shaped portion 42b. Installed in a separated state.

  The distance between the lower ends of the left and right V-shaped portions of the W-shaped portion 42b is wider than that of the conventional one, and the W-shape is also formed flat. The shape of the substantially trapezoidal portion 42c at the center is not limited to that shown in the drawing, and various modifications can be made.

  As shown in FIGS. 1 and 2, the lower end fixture 26 includes a rectangular frame-shaped connecting ring 26a attached to the lower portion of the lower belt 23, and a lower side or bottom portion of the school bag body 12 that locks the connecting ring 26a. The upper and lower inner sides of the pair of left and right connecting rings 26a are respectively twisted outwardly. In the present embodiment, the locking portion 26b is rotatably attached to a mounting substrate that is attached to the bottom 14 side of the school bag body 12.

  The lower part 21b of the upper belt 21 is attached to a connecting tool 25 such as a vision and a buckle at the tip 23b of the lower belt 23 attached to the bottom part 14 of the school bag body 12 so that the length can be adjusted. As shown in FIG. 3, a locking hole 29 is formed in the lower portion 21 b of the upper belt 21 at an appropriate interval, and a locking pin 25 a of the connector 25 is inserted and locked in the locking hole 29.

  Similarly to the rectangular frame-shaped connecting ring 26a shown in FIGS. 1 and 2, the upper portion of the rectangular frame body 25b of the connector 25 is twisted outward to give a twist, thereby connecting the pair of left and right shoulder belts 15 to each other. The position of the tool 25 can be outward.

  Although not shown, the back plate portion 13 of the school bag body 12 is composed of a core material formed of a hard synthetic resin plate or the like, a pad material with good cushioning attached to the surface of the core material, The pad material is made of foamed polystyrene, foamed urethane or the like. An appropriate backing fabric is bonded to the back side of the core material.

  As shown in FIG. 6, the pair of left and right upper belts 21 of the shoulder belt 15 are hung on the shoulders of the user. Therefore, it is preferable to use different materials for the inner side and the outer side. A padding having cushioning properties can be provided between them.

  As shown in FIG. 3, the upper portion of the upper belt 21 of the shoulder belt 15 is bent outwardly to form a first bent portion 22 a, and protrudes inward from the center to the lower portion of the upper belt 21. The second bent portion 22b is formed by being bent in the state. Further, the middle portion of the pair of left and right lower belts 23 is bent inward or outward to form a third bent portion 24a.

  In the present embodiment, the third bent portion 24a is formed by bending in an inwardly convex state, but the bent state is not limited to the illustrated one. Further, the second bent portion 22b can be omitted, or the bent portion of the second bent portion 22b can be reduced.

  Since the second bent portion 22b of the upper belt 21 is twisted outward, and the third bent portion 24a of the lower belt 23 is bent inwardly, it is more at the position from the waist to the side. It effectively turns outward and can fit gently on the child's flank.

  Further, since the lower belt 23 is formed with a third bent portion 24a bent in an inwardly convex state as compared with the case using the linear lower belt 23, the tip 23b of the lower belt 23 is outward. Since it is bent, the amount of rotation when the lower belt 23 is rotated to a predetermined position can be halved, and it can be easily carried on the back when the distance between the pair of left and right shoulder belts 15 is increased.

  According to such a configuration, the child can be gently fitted to the flank. Further, the second bent portion 22b of the upper belt 21 and the third bent portion 24a of the lower belt 23 can be matched.

  According to the present invention, the lower end fixture has a square frame-shaped connecting ring attached to the lower portion of the lower belt, and a locking portion attached to the lower side of the school bag body for locking the connecting ring, Since the upper inner side of the pair of connecting rings is formed to be twisted outward, the lower belt can come out at an angle from the lower side of the school bag main body, and on one side of the lower part of the pair of left and right shoulder belts It is possible to prevent a certain inner end from hitting the user's flank and lateral waist at an acute angle.

  In addition, the upper belt can be prevented from hitting the neck, it can be used comfortably on the back of the user by preventing discomfort and pain from the user, and the structure is simple and economical. In addition, it is possible to obtain a backpack belt mounting structure that can improve the appearance.
