Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

As shown in FIG. 4 and FIG. 5 , a preferred embodiment of the waterproof shoes of the present invention includes a shoe unit 10 and a shoe cover unit 20 .

Referring to Fig. 6 and Fig. 7, the shoe unit 10 has a body 11 which is made of cloth material and can wrap the sole of the foot, a vamp member 12 which is sewn and fixed on the body 11, and a lining set on the body 11. The body 11 and the inner lining 13 inside the shoe upper 12 , a reinforcement 14 fixed on the inner side of the body 11 , and a midsole 15 fixed on the bottom of the body 11 . The main body 11 has a toe portion 111 (the reinforcing member 14 is fixed on the inner side of the toe portion 111 ), a heel portion 112 opposite to the toe portion 111 and a top edge formed by the toe portion 111 . The rim portion 113 extends to the top edge of the heel portion 112 . The upper part 12 of the present embodiment is made of leather material that can firmly support the ankle, and has a bottom ring portion 121 lapped on the outside of the ring portion 11 and a strip connecting the bottom ring portion 121 and the ring portion. 131 sewing thread 122 fixed by sewing. The inner lining 13 is made of soft and comfortable material. The reinforcing part 14 is made of metal, and is lined between the body 11 and the lining part 13 corresponding to the toe part 111 in accordance with the shape of the toe part 111, so that the waterproof shoes of the present invention can also be used as Safety shoes use.

Preferably, a waterproof layer 16 made of waterproof and breathable material (such as Gortex material) can be added between the upper part 12 and the inner liner 13 .

The shoe cover unit 20 can be made of waterproof materials such as rubber, polyurethane rubber (PU), thermoplastic polyurethane elastomer (TPU), thermoplastic rubber (TPR), and has a wrapping on the outside of the main body 11. The covering part 21 and a shoe outsole 22 arranged at the bottom of the covering part 21, the covering part 21 has a top ring part 211 corresponding to the ring edge part 113 and the bottom ring part 121, and the top ring part 211 can cover The sewing thread 122 is coated on the upper member 12 .

And as shown in FIG. 8 , the covering part 21 of the shoe cover unit 20 is molded, and a last 200 is used to set the inside of the shoe unit 10 , and the shoe unit 10 is inserted into a molding Inside the mold 100, when the liquid rubber material is poured into the molding mold 100 by injection or pouring, and after molding, the covering part 21 can be directly covered and fixed on the shoe unit 10, and the covering part 21 When molding, the liquid rubber material will penetrate into the sewing line 122, and the top ring part 211 will cross the sewing line 122, the bottom ring part 121 and extend to the upper part 12 .

Therefore, the covering part 21 is molded and covered and fixed on the shoe unit 10 , and the liquid glue forming the covering part 21 penetrates into the sewing line 122 and the top ring part 211 The stitching line 122 and the bottom ring portion 121 are extended to the upper part 12, so that the stitching line 122 is completely covered, and a better anti-seepage and waterproof effect is produced.

As shown in Figure 9 again, if the material of the shoe outsole 22 and the covering part 21 are different, the covering part 21 of the shoe cover unit 20 is directly molded and covered on the shoe unit 10 Afterwards, the shoe outsole 22 made independently can be bonded into one body with the covering member 21 (as shown in FIG. 4 ). If the shoe outsole 22 and the covering part 21 are made of the same material, the shoe outsole 22 and the covering part 21 can be integrally molded directly inside a molding mold (not shown).

Therefore, compared with the existing waterproof shoes in Fig. 1 and Fig. 2, the utility model can omit the sewing work of combining the shoe unit 10 and the shoe cover unit 20, and can produce the expected waterproof effect, and has the advantage of reducing the cost. effect. Compared with another existing waterproof shoe shown in FIG. 3 , the utility model utilizes the covering part 21 of the shoe cover unit 20 to be directly molded and coated on the shoe unit 10 to produce a waterproof effect. The applied process is quite simple, the manufacture is also quite easy, and the cost is also low. In addition, because the combination of the shoe unit 10 and the shoe cover unit 20 does not require sewing, the material selection of the shoe cover unit 20 is relatively wide, and rubber, PU, TPU, TPR and other materials can be used.

It is worth noting that if the waterproof layer 16 is not provided, waterproof glue can also be applied on the surface of the upper part 12 for waterproof treatment, which can also make the whole waterproof shoe completely waterproof from bottom to top.
