It is configured to prevent the phenomenon. That is, the nut 34 is rotated within the upper and lower rotation range of the waist support plate 1 by the holder 13 to prevent the loosening phenomenon.

Figure 2b is a front view of Figure 2a, Figure 2c is a cross-sectional view of the line AA of Figure 2a, the backrest plate 1 is a cross-shaped or vertical and so that the band strap 240 of the waistband 200 can be inserted and locked A plurality of first fixing holes 12 are formed in a horizontal flat form, and hinge hinge portions 31 composed of a pair of side support plates 312 and 312A and an insertion space portion 313 are integrally formed at both sides thereof. And a nut 34 (see FIG. 1) fastened to a bolt 33 inserted into a hinge hole B 311 penetrating through the side support plates 312 and 312A on one side of the hinge protrusion 31. The holder 13 is integrally formed with an upper support plate 131 and a lower support plate 132 having an interval corresponding to the nut 34 which can be held, and an insertion space 313 therebetween.

Figure 3 is a perspective view showing the structure of the back support plate support of the present invention, as shown in the back support plate 30 of the present invention is a fitting portion 301 having a frame through hole 311 is opened to one side A pair of supporting plates A 302A and a supporting plate B 302B, which are formed at the rear side and have hinge holes A 312 at the front side at both ends of the fitting portion 301, are extended to be in contact with each other, and thus the support plate fixing holes 322 are formed. It is configured to be coupled to each other by fastening through the bolt, the fitting portion 301, the frame fastening hole 321 is formed up and down and the lower back plate support by bolt fastening through the frame fastening hole 321 ( 30 is configured to be fixed on the backpack frame 100 (see Fig. 1).

The back support plate 30 configured as described above is formed in the weld 301 by inserting the weld 301 into the backpack frame 100 in a state where the support plate A 302A and the support plate B 302B are opened to both sides. The back support plate 30 is fixed to the backpack frame 100 by fastening the bolt through the frame fastening hole 321, and the support plate A 302A and the support plate B 302B are supported by the support plate fixing hole 322. Are joined to each other by bolting through).

Figure 4 is a perspective view showing another embodiment of the back support plate support of the present invention, as shown in the back support plate 30 of the present invention is a frame through-hole 311A having an opening portion 301B to the rear side A fusion fitting portion 301A having a rear side is formed, and a support plate 302 having a hinge hole A 312A is extended to the front side of the fusion portion 301A, and the frame is fastened up and down to the fusion portion 301A. Ball 321A is formed.

The waist support plate 30 is configured as described above, the fitting portion 301A is elastically coupled to the backpack frame 100 by the opening portion 301B, the frame fastening hole 321A formed in the fitting portion 301A By fastening the bolt through the waist plate support 30 is fixed to the backpack frame 100, which has the advantage that can be faster and simpler assembly than the waist plate support 30 of one embodiment.

5 is an enlarged cross-sectional view showing the assembled state of the present invention, first, the waist support plate support 30 is fixed to the backpack frame 100 as described above, the waist support plate (outside the back support plate 30) ( The insertion space 313 between the side support plate A 302A and the side support plate B 302B constituting the hinge protrusion 31 of 1) is inserted, and one holder portion 13 of the hinge protrusion 31 is inserted. The nut 34 is inserted into it.

In this state, the backpack strap fixture 2 is abutted to the outside of the hinge protrusion 31 of the waist support plate 1, the hinge hole C 32 formed in the backpack strap fixture 2 and the hinge of the waist support plate 1 The bolt 31 is inserted through the hinge hole B 311 and the hinge hole A 312 formed in the protrusion 31 and the waist support plate 30 to be fastened to the nut 34 to complete a series of assembling. Will be.

In the present invention assembled as described above, when carrying a backpack, the backrest plate (1) coupled with the waistband 200 (see Fig. 1) is to be in close contact with the user's waist, the backpack frame 100 is a hinge coupling portion (3) Since the front and rear rotation is possible around the bolt 33, the backpack frame moves together when the user moves back and forth, such as when the user leans back, so that the load of the backpack is placed on the shoulder strap of the backpack. It is distributed and not concentrated.

As described above, the present invention is configured to rotatably support the backpack frame so that the waist plate is rotatably supported on the backpack frame to carry the backpack and move the body, for example, when the waist is folded, the backpack is with the body. As the load of the backpack is distributed to the whole body instead of being concentrated on the shoulders, the fatigue is remarkably reduced even when the backpack is carried for a long time, and thus the convenience of use can be achieved. .

In addition, the present invention is composed of an elastic body that is opened to one side of the waist restraint support to be assembled by only the simple fitting operation while forming the hinge protrusion of the waist restraint structure to support both sides of the waist rest simplicity of assembly And the effect of further increasing efficiency and robustness.

In addition, the present invention by integrally forming the holder portion to hold the nut fastened to the bolt constituting the hinge coupling portion in the waist support can not only prevent the loosening of the nut in advance, but also because of the durability of the hinged state It is effective to maintain.
