Description

Technical Field

[0001] The invention relates to a pair of shoes, in particular to a method for manufacturing a pair of shoes with an integrated upper and an inner lining. Background Art

[0002] like Figure 1 , 2 As shown, conventional waterproof knitted socks shoes generally include a waterproof inner sleeve 1, an inner lining 2 fixedly arranged inside the waterproof inner sleeve 1, a sock-like knitted upper 3 arranged on the waterproof inner sleeve 1, and a sole 4 fixedly arranged at the bottom of the sock-like knitted upper 3. The sock-like knitted upper 3 has a folded top portion 301. The folded top portion 301 is folded inwardly to the inside of the inner lining 2, and the folded top portion 301 is sewn together with the waterproof inner sleeve 1 and the inner lining 2 by a sewing thread 302.

[0003] Since the inner lining 2 and the sock-like knitted upper 3 of the waterproof knitted sock shoe are two-piece structures manufactured separately, in order to cover the top edge of the waterproof inner sleeve 1 and the top edge of the inner lining 2 to enhance the appearance of the shoe, the folded top portion 301 needs to be folded inwardly to the inside of the inner lining 2 and sewn and fixed by the stitching 302. However, the stitching 302 sewn through the waterproof inner sleeve 1 will not only affect the waterproof effect of the waterproof inner sleeve 1 at the user's ankle and cause the possibility of water seepage, but also cause friction on the user's ankle, affecting the user's wearing comfort.

[0042] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0043] See also Figure 3 , is an embodiment of the method for manufacturing a shoe with an integrated upper and lining of the present invention, as Fig.16 , 17 18 shows a shoe 100 manufactured by the manufacturing method of the shoe with integrated upper and lining. The shoe 100 includes an inner sleeve unit 10, an upper-lining unit 20, a bonding unit 30, a sole unit 40, and an adhesive layer 50.

[0044] It should be noted that the following descriptions of directionality are based on Fig.17 , 18 Directions shown are used as a guide.

[0045] The manufacturing method of the shoe with integrated upper and lining comprises the following steps:

[0046] Step 510 (see Figure 3 ):like Figure 4 , 5 As shown in FIG. 6 , an upper-lining unit 20 is prepared. The upper-lining unit 20 includes an inner lining structure 21 and an upper structure 22 connected to the inner lining structure 21. In the present embodiment, the inner lining structure 21 and the upper structure 22 of the upper-lining unit 20 are integrally woven.

[0047] The inner structure 21 has a first toe portion 211 , a first heel portion 212 opposite to the first toe portion 211 in a length direction X, and a first connecting portion 213 around an axis L.

[0048] The upper structure 22 has a second connecting portion 221 surrounding the axis L and connected to the first connecting portion 213, an open end 222 away from the second connecting portion 221 in the length direction X and forming an insertion opening 225, a second heel portion 223 corresponding to the first heel portion 212 and opposite to the open end 222 in the length direction X, and a shoe mouth portion 224 surrounding the axis L.

[0049] The shoe opening portion 224 is integrally connected between the first connection portion 213 of the inner lining structure 21 and the second connection portion 221 of the upper structure 22. In this embodiment, the shoe opening portion 224 is integrally woven and connected between the first connection portion 213 of the inner lining structure 21 and the second connection portion 221 of the upper structure 22. The shoe opening portion 224 of the upper structure 22 has a front pull ear 226, a rear pull ear 227 opposite to the front pull ear 226 in the longitudinal direction X, and two side straps 228 connected between the front pull ear 226 and the rear pull ear 227 and arranged opposite to each other in a transverse direction Y (see FIG. 2 ). Fig.17 ).

[0050] The first connection portion 213 of the inner lining structure 21 of the upper-inner unit 20 and the second connection portion 221 of the upper structure 22 are integrally connected together. In the present embodiment, the first connection portion 213 of the inner lining structure 21 and the second connection portion 221 of the upper structure 22 are integrally woven together via the shoe mouth portion 224.

[0051] The upper-inner unit 20 has an inner surface 25 and an outer surface 26 .

[0052] In this step 510 (see Figure 3 ), such as Figure 7 , 8 As shown, the upper-lining unit 20 is turned inside out so that the inner surface 25 of the upper-lining unit 20 is exposed. In this embodiment, after the inner surface 25 of the upper-lining unit 20 is exposed, the lining structure 21 defines a wearing space 23, and the upper structure 22 defines a last insertion channel 24 connecting the last insertion opening 225 and the wearing space 23.

[0053] Step 520 (see Figure 3 ):like Fig. 9 As shown, an adhesive 200 is coated on the inner surface 25 of the upper-inner unit 20. In this embodiment, the adhesive 200 is coated on the inner surface 25 of the upper-inner unit 20 by spraying.

[0054] Step 530 (see Figure 3 ):like Fig.10 As shown, the inner lining structure 21 is put on a shoe last 300 .

[0055] In this embodiment, the shoe last 300 is inserted into the wearing space 23 of the inner structure 21 through the last insertion opening 225 and the last insertion channel 24 of the upper structure 22 , so that the inner structure 21 is put on the shoe last 300 .

[0056] Step 540 (see Figure 3 ):like Fig.11As shown, the adhesive 200 is applied on the inner surface and the outer surface of the inner sleeve unit 10. In this embodiment, the adhesive 200 is applied on the inner surface and the outer surface of the inner sleeve unit 10 by spraying. In addition, it can be understood that if the adhesive 200 applied in step 520 can provide sufficient adhesion, step 540 can be omitted.

[0057] Step 550 (see Figure 3 ):like Fig.12 As shown, the inner sleeve unit 10 is inserted into the inner structure 21. In this embodiment, the inner sleeve unit 10 defines an inner space 14 for the inner structure 21 to penetrate.

[0058] In this embodiment, the inner sleeve unit 10 has an inner sleeve toe portion 11 corresponding to the first toe portion 211 of the inner lining structure 21, an inner sleeve heel portion 12 corresponding to the first heel portion 212 of the inner lining structure 21 and opposite to the inner sleeve toe portion 11 in the length direction X, and a top opening end portion 13 around the axis L. It should be noted that the directionality of the top opening end portion 13 is Fig.17 , 18 Directions shown are used as a guide.

[0059] In this embodiment, if Fig.19 As shown, the inner sleeve unit 10 includes a lining layer 15, a surface fabric layer 16, a support layer 17 fixed between the lining layer 15 and the surface fabric layer 16, and a moisture-permeable and waterproof layer 18 fixed to the outer surface of the surface fabric layer 16. Preferably, the support layer 17 is an upright pile layer woven between the lining layer 15 and the surface fabric layer 16, but is not limited to this. In other variations, the support layer 17 can also be a foam layer.

[0060] In this embodiment, the inner sleeve unit 10 can be sewn from a piece of cut material, and a waterproof strip is adhered at the sewing position, but it is not limited thereto.

[0061] Step 560 (see Figure 3 ):like Fig.12 , 13 As shown, the upper structure 22 is turned inside out so that the upper structure 22 is reversely sleeved on the inner sleeve unit 10 , and the shoe opening portion 224 is exposed again.

[0062] Step 570 (see Figure 3 ):like Fig.13 , 14 As shown in FIG. 15 , the open end 222 of the upper structure 22 is positioned on the bottom surface of the inner sleeve unit 10 .

[0063] In this embodiment, the open end 222 of the upper structure 22 is first folded to close the last opening 225 , and then the open end 222 is temporarily positioned on the bottom surface of the inner sleeve unit 10 opposite to the top open end 13 .

[0064] It is understandable that the adhesive 200 between the inner sleeve unit 10 and the inner lining structure 21 will solidify into an inner adhesive layer 31 of the adhesive unit 30 , and the adhesive 200 between the inner sleeve unit 10 and the upper structure 22 will solidify into an outer adhesive layer 32 of the adhesive unit 30 .

[0065] Step 580 (see Figure 3 ):like Fig.15 , 16 As shown, the sole unit 40 is fixed on the upper structure 22 .

[0066] In this embodiment, an adhesive 400 is applied to the sole unit 40 and the upper structure 22 respectively, so as to fix the sole unit 40 to the bottom of the upper structure 22 .

[0067] It is understood that the adhesive 400 between the sole unit 40 and the bottom of the upper structure 22 will cure into the adhesive layer 50 .

[0068] Step 590 (see Figure 3 ):like Fig.15 , 16 As shown, the shoe last 300 is pulled out from the inner structure 21 .

[0069] As shown in 16, 17, and 18, the shoe 100 can be manufactured. In this embodiment, the first connection portion 213 of the inner lining structure 21 is higher than the first heel portion 212 in a height direction Z, the second connection portion 221 of the upper structure 22 is higher than the second heel portion 223 in the height direction Z, the shoe mouth portion 224 is higher than the top open end 13 of the inner sleeve unit 10 in the height direction Z, and the open end 222 is positioned on the bottom surface of the inner sleeve unit 10.

[0070] Through the above description, the advantages of the present invention can be summarized as follows:

[0071] 1. The present invention utilizes the design of integrally connecting the lining structure 21 and the upper structure 22 of the upper-inner unit 20, so that the inner cover unit 10 can be directly covered between the lining structure 21 and the upper structure 22 after being combined with the upper-inner unit 20. Compared with the prior art, the present invention does not need to sew the lining structure 21 and the upper structure 22 together by sewing to cover the top opening end 13 of the inner cover unit 10. In this way, the present invention will not only not destroy the waterproof effect of the inner cover unit 10 at the user's ankle, but also will not cause friction on the user's ankle by additional sewing, thereby improving the user's wearing comfort.

[0072] 2. Compared with the prior art, the inner lining structure 21 and the upper structure 22 of the upper-inner lining unit 20 used in the present invention are a single-piece structure that is integrally connected. The inner lining structure 21 and the upper structure 22 can be woven into one piece, which not only does not need to be manufactured separately, but also can omit the subsequent sewing process of sewing the inner lining structure 21 and the upper structure 22 together. The present invention can simplify the process and reduce the manufacturing cost.

[0073] In summary, the manufacturing method of the shoe with integrated upper and lining of the present invention not only does not destroy the waterproof effect of the inner sleeve unit at the user's ankle, but also improves the user's wearing comfort, so it can indeed achieve the purpose of the present invention.

[0074] The above are only embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
