When the inner covering layer 41 is unfolded, the folded-section 31 of the shoulder strap 3〇 can be placed on the inner covering layer 41. Then the inner covering layer 41 is folded in pairs, and then the folded section can be folded. The shoulder strap 30 which is folded and fixed in the inner covering layer 41 is fixed in length. ‘ The outer fastening layer 42 has a larger area than the inner cladding layer 41, so that the inner cladding layer 41& can be hidden inside when the outer buckle welding is performed. The two sides of the real outer fastening layer 42 can also be provided with a devil glue or other buckles 44 which can be fixed to each other. Therefore, when the outer fastening layer 42 is folded over the inner cladding layer μ, the pressure is applied. The buckle 44 is fastened, so that the shortened shoulder strap 3〇 can be fixed, and the fixed shoulder strap 30, the inner covering layer 41 and the outer fastening layer 42 are at the same time, because the first and second fastening members 5 〇, 6〇 interlocking each other, because 3=shoulder Γ can maintain the adjusted length, while also increasing the shoulder strap, 7 , so that the folding section 31 of the shoulder strap 30 is not because of & When the power is loose.曰口为承#田f — mm'1 reveals two types of shoulder straps for this creative backpack. In the third figure, the backpack 1Q is designed to be flat, and a buckle u is arranged on both sides of the =10, and the shoulder strap 30 is hooked at the two ends of the shoulder strap 30, and the user can use the shoulder strap 30 to side or diagonally. The back mode can be used for two purposes. At this time, the shoulder strap 30 can be placed to the longest length, so that the original can be used as a briefcase or a side strap, and the folded body buckle can be used as a user. Padded shoulders. The tip is to create a dual-use shoulder strap as a briefcase or side backpack icon. 'Shoulder strap 30 hooks 32 are still fastened by a spoon float 40 〇%11, and the shoulder strap 30 can be shortened as described above, and After the stacking body 40 is folded up, the handle of the backpack 1〇 can be formed, and the user can carry the back sentence by hand in the case of = 9 M321246 ^ - as the side strap or the briefcase of the briefcase, the foregoing Creation of the original German, βρ π «τ Stan i ▼ use 'after the shortened length adjustment, the material is formed into a handle for multi-purpose purposes.

In the second embodiment of the second embodiment, the folding section 31, the tpp, and the two fasteners 50 and 70 are fastened to each other when the fasteners 5, 6 are fastened together, and the folding section 31 is selected: ?::35 The unfolded part of the raft is longer, so when the user chooses I, one can be: 6 〇 (four) square to the shortest ' as a handle for the user to carry. ^ ^, brother nine to the young twelve Show), can be added to the length of the cable for different needs -, to achieve the adjustment length: the user side back or cross-body backpack, as shown in the back figure 'this creation in addition to the aforementioned side back or oblique & 1 & work, can also be used as a back strap of the backpack, and the same figure shows 'the shoulder (four) includes - fixed end Z opposite end ^ from / end set on the back side of the backpack 10, a second hook on the fixed end Soil 33, and the upper edge of the front side of the back pack is provided with a hook ring: or =: from the coffee shop ^ in the back 勹 - use 0 守 'send the fixed end of the shoulder strap 3 10 10, and the free end is set to hang Hook 32 is attached to the M321246 on the 1st backpack. The first hook is 33' to allow the user to carry the backpack in the back. When folded, 'as shown in Figures 14 and 16' First, the hook hook is detached from the first hook ring on the back raft, and then the shoulder strap 30 is folded, and then the folded section 31 is folded and wrapped around the covering body 4 according to the previous method. • Hook 32 buckles and hangs on the second buckle (10), which can be used as the handle of the backpack 10. If the hook is provided on the free end, the hook 32 is fastened to the first hook. 3 0 is also connected to the back side of the backpack, forming a backpack with a shoulder strap 30 on the back side of the backpack. When the hook 32 of the free end is fastened to the second hook ring _ 34, the shoulder strap 30 is respectively connected at both ends. It is arranged on the front and rear sides of the backpack, and has a backpack 1 具有 with a shoulder strap 30 on both sides. The backpack 1 with the shoulder straps on both sides is inserted into the raft. As shown in Figure 17, when the creation is carried out, the overall matching with a hard briefcase or backpack 10 (such as leather or breathable leather), the shoulder strap 30 can be added with a number of the same material than the shoulder strap 3G is a hard spacer 8G; since the material of the shoulder strap 3〇 between the spacers 80 is softer than the spacer 8〇, it can be bent by the soft shoulder strap 30 section. And the spacer 8 is placed in the covering body 40. The first, second, third=50, 60, 70 can be disposed on the back of the shoulder strap 3〇, 俾Can be hidden under the shoulder strap • 30 without affecting its appearance. As shown in Figure 18, this creation can be placed between the first and second fasteners 50, 6〇 on both sides of the shoulder strap 3〇. The position, the Japanese character buckle 90 and the mouth piece 9 which are conventionally adjusted for the length of the shoulder strap are arranged such that the shoulder strap 30 can be adjusted in length between the Japanese character buckle 90 and the mouth piece 91 to facilitate adjustment by users of different heights.
