In addition, an auxiliary loading unit 640 is formed between the first backpack member 610 and the second backpack member 620. The auxiliary loading part 640 is fixed to both lower ends of the first backpack member 610 and the second backpack member 620 by sewing or by combining separate hinges (not shown). The auxiliary loading part 640 is configured such that the first backpack member 610 and the second backpack member 620 can be unfolded in opposite directions in a state where the surface can be exposed.

The auxiliary loading unit 640 may use a structure described in Korean Patent Registration No. 10-2162883, which was filed and previously registered by the inventor of the present invention, so that the distance can be adjusted within a predetermined width range.

In addition to the structure described in Korean Patent Registration No. 10-2162883, the auxiliary loading part 640 of the present invention uses a pair of thin panels 640a and 640b to be folded in half based on the central part (dotted line display part) as shown in FIG. can be configured.

When the thin panels 640a and 640b constituting the auxiliary loading part are folded, the folded positions do not protrude outward from the first backpack member 610 and the second backpack member 620, but are folded inward and overlapped. do.

Referring to the structure of FIG. 5 , the auxiliary loading part 640 is fixed to the lower ends of the first backpack member 610 and the second backpack member 620 .

The fixing position of the auxiliary loading part 640 is not limited to the structure of FIG. 5, and when goods are loaded on the auxiliary loading part 640, the auxiliary loading part sags downward under the influence of the load of the goods, causing the first backpack member 610 to And considering that the lower end of the second backpack member 620 is exposed to the outside, it may be configured in a structure fixed at an upper position spaced apart from the lower ends of the first backpack member 610 and the second backpack member 620 at a predetermined interval.

When the auxiliary loading part 640 is not in use, the first backpack member 610 and the second backpack member 620 are closely attached to each other and can be fixed. The fixation of the first backpack member 610 and the second backpack member 620 corresponds to a plurality of auxiliary fixing belts 658 configured in the first backpack member 610 and the auxiliary fixing belt 658, as shown in FIG. It is made by fastening a plurality of buckles 659 configured in the second backpack member 610 to each other. Of course, the auxiliary fixing belt 658 is configured to be adjustable in length.

Another method of fixing the first backpack member 610 and the second backpack member 620 to each other when the auxiliary loading part 640 is not used is the rear edge 610b of the first backpack member 610 as shown in FIG. ) and the front edge 620b of the second backpack member 620 may be fixed by installing fasteners 631.

The main fixing belts 671 and 672 for the auxiliary loading unit, which have not been described, may be mainly used when loading articles in the auxiliary loading section 640 .

As shown in FIGS. 9 and 10, the main fixing belts 671 and 672 for the auxiliary loading part are the back plate 615 of the first backpack member 610, the lower side of the auxiliary loading part 640, and the front surface 620a of the second backpack member 620. ) is arranged to pass through the inner side. That is, the first backpack member 610 completely wraps the goods loaded in the auxiliary loading unit 640 between the rear surface 610a of the first backpack member, the front surface 620a of the second backpack member, and the auxiliary loading unit 640. It is composed of a structure that can be fastened to.

In particular, the backpack 600 of the present invention, as shown in FIG. 5, includes the rim 610b of the rear surface 610a of the first backpack member 610 with the auxiliary loading part 640 interposed therebetween, and the second backpack member ( U-shaped elastic rods 680 and 690 are inserted and fixed to the edge 620b of the front surface 620a of the 620, respectively. When the U-shaped elastic bar is made of steel, a diameter of about 3 mm is sufficient, but steel having a diameter in the range of 3 to 10 mm may be used depending on the size or strength of the backpack.

The rear surface 610a of the first backpack member 610 and the front surface 620a of the second backpack member 620 are made of thin, variable materials such as fabric, nonwoven fabric, and leather.

Even if thin and variable materials are used for the rear surface 610a of the first backpack member 610 and the front surface 620a of the second backpack member 620, the U-shaped elastic bars 680 and 690 are the first backpack member. Since the back surface 610a of the first backpack member and the front surface 620a of the second backpack member are pulled flat by the elasticity acting outward, the rear surface 610a of the first backpack member and the front surface 620a of the second backpack member are always flat. It can keep its shape. Even if the shapes of the rear surface 610a of the first backpack member 610 and the front surface 620a of the second backpack member 620 are temporarily deformed due to the loading of items, they immediately return to their original positions after the items are removed, and It has the advantage of maintaining its original appearance. In addition, since the rear surface 610a of the first backpack member 610 and the front surface 620a of the second backpack member 620 do not need to be made of a thick panel or the like, the weight of the backpack is reduced.

In addition, as shown in FIGS. 5 and 10, a securing means composed of a protruding frame 700 for securing is fixed to the back plate 615 of the backpack and is configured to extend by a predetermined length toward the upper side of the backpack.

The protruding frame 700 for securing, constituting the securing means, is fixed to the back panel 615 by forcibly fitting a pair of vertical poles 710, 720, 730, 740 constituting the left and right poles on both sides of the back panel 615 of the backpack. It is provided with a pocket-type groove (not shown) that can be used. The protruding frame 700 for fixing is configured to be detachably inserted into the bag-type groove and can be selectively used only when the backpack sags due to the heavy weight or bulkiness of the items loaded on the first backpack member and the second backpack member. there is.

The protruding frame 700 for securing is, for example, as shown in FIGS. 5, 6 and 8, the left and right poles 710, 720, 730, 740 constituting a pair of vertical poles, respectively, standing on both sides, and a horizontal pole coupled across the top. 770 and a main fixing belt 671 for auxiliary loading that fixes the first backpack member and the second backpack member to the top of the left and right poles 710 and 730 or to the horizontal pole 770 protruding upward by a predetermined length of the backpack One or more belt supports 751 and 761 supporting a belt selected from among the and auxiliary fixing belts 658 may be configured.

The belt supports 751 and 761 may be configured in pole coupling bundles 750 and 760 for fixing the horizontal poles 770 and the left and right poles 710 and 730.

The pole coupling bundle (750,760) serves as a pole coupling portion, and the pole coupling bundle 750 on the right and the pole 710 on the right have both ends coupled via the pivot shaft 755, and the pole coupling bundle 760 on the left Both ends of the pole 730 on the left side and the pivot shaft 765 are coupled to each other. The rotation shafts 755 and 765 have a width larger than the diameter of the left and right poles 710 and 730 so that the left and right poles 710 and 730 can cross each other when folded by rotating the left and right poles 710 and 730 It is preferable to configure so that the fixed ends of the poles 710 and 730 can slightly move in the longitudinal direction of the pivot shafts 755 and 765.

Horizontal pole 770 is threaded in the opposite direction on both sides are formed coupled to the threaded groove of the pole coupling bundle (750 760), or may be integrally configured.

The reason why the pole joint is configured as described above is to reduce the volume to the extent that it can be stored in a backpack when the protruding frame 700 for fixing is separated from the backpack and dismantled, and to prevent loss of parts.

The protruding frame 700 for fixing of the present invention is made of a plurality of pole couplings made of metal or non-metallic material, and each pole coupling portion is configured with a pole diffraction means capable of folding an adjacent pole.

The rotational shafts 755 and 765 act as coupling parts and diffraction means of the left and right vertical poles 710 and 730 adjacent to the horizontal poles, and a different type of pole diffraction means 1900 is between a pair of left and right vertical poles. It consists of

The pole diffraction means 1900 is linked to both ends of a pair of vertical poles 710 and 720 and 730 and 740 adjacent to each other as shown in FIG. 7, for example, and is adjacent to the vertical poles 710 and 720 adjacent to each other based on both ends of the adjacent poles. The vertical poles 730 and 740 to be diffracted. The pole diffraction unit 1900 includes a lattice-type plate 1901 having the same width as the diameter of the pole and having one corner of both ends arc in the same direction, and the vertical plate 1901 so that both ends of the lattice-type plate 1901 are fitted. A fixation that couples the incision grooves 1902 and 1903 of the poles 710 and 720 and 730 and 740, respectively, and the lattice-shaped plate 1901 whose ends are fitted into the incision grooves 1902 and 1903 to the incision grooves in a diffractive manner. It consists of pins 1904 and 1905. The poles 710 and 720 (730 and 740) and the lattice plate 901 are coupled by the fixing pins 1904 and 1905, and the overlapping portion forms a square based on the coupling holes 1906 and 1907 of the fixing pins.

As described above, by configuring the pole diffraction means 1900 between the vertical poles, diffraction to at least one side is prevented when a pair of vertical poles constituting the left and right poles form a straight line with respect to the grid-shaped plate 1901. An end of the incision groove and an end of the lattice-shaped plate may come into contact with each other to be stopped.

The pole diffraction means 1900 may support vertical poles 710 and 720 and 730 and 740 in a straight line as shown in FIG. 6 or diffract and fold the poles 710 and 720 and 730 and 740 as shown in FIG.
