The design is achieved in that at first with two lining (solid, wear-resisting, best waterproof of knapsack outer shell fabric that quality is different; The knapsack internal layer can be used soft lining) and space wadding (as the intermediate layer, also available other cotton material) be sewn into similar oblong-shaped, and in position add slide fastener, backpack strip, thread gluing, snap-fastener.

The design is simple in structure, and is easy to use, and a multi-purpose pack can be made into the different plurality of specifications of thickness and waterproof and non-watertight type.

Below be the concrete grammar of implementing the design: Fig. 1 is the outer coversheet expanded view, at first interior outer facing material and intermediate layer space wadding is cut into diagram 1 shape with reference to Fig. 1, and intermediate layer space wadding frame should be more smaller than inner and outer fabrics frame.To cut out the fastening straps of making 2, braces 3, restraint zone 4, slide fastener 5 are made on the correct position of outer shell fabric by thin worry wire.Then, interior outer facing material, intermediate layer space wadding partly are stitched together into three interlayers 1 along three interlayers, 1 frame fine dotted line, the disengaging of space wadding layer in the middle of being to prevent can evenly be made several lines in that three interlayers 1 are vertical or horizontal.Fig. 2 is the internal surface layer expanded view, for remedying the breach that uses as cotton-padded mattress shown in Figure 1, with the soft lining of bilayer, therebetween space wadding layer, each independently makes two cushion blocks by 6 and 8 shapes, again by 6 and 8 worry line part, respectively cushion block is made on the inner layer surface of three interlayers 1, for preventing that cushion block 6 and 8 from being moved in bed, can be at cushion block 6, fixed in position with snap-fastener or thread gluing between 8 and 1, when the receipts cage becomes knapsack, it is inwardly folding to press dotted line with 6 and 8, be to give the built-in bag of making earlier, Fig. 3 and Fig. 4 be with the both sides slide fastener when pulling into knapsack just, the reverse side schematic diagram.

According to the made knapsack of the design, both can adorn band luggage and articles, baby, can be used as baby bunting again, rain and snow, warming, comfortable; After opening slide fastener and launching, both can be used as the tour in the field and had a rest and use bed, can be used as the bedding use that migrant job, student have a rest night again, very effective to moistureproof winter protection.
