Technical Field
[0001] The present invention relates to a pair of shoes, in particular to a pair of breathable and waterproof shoes with a shoe upper and a shoe cover sealed synchronously. Background Technology
[0002] If Figure 1 、 2 , 3 shows an existing breathable and waterproof shoe with wearing coverage (Taiwan New Patent No. M618093), which includes an upper unit 1, a shoe-shaped inner sleeve unit 2, an adhesive layer 3, a tightening unit 4, and a sole 5. The adhesive layer 3 is fixed between the upper unit 1 and the shoe-shaped inner sleeve unit 2. The tightening unit 4 includes two tightening decorative pieces 401 symmetrically arranged on the left and right sides of the upper unit 1 and connected to the sole 5, and a tightening belt 402 inserted between the tightening decorative pieces 401. The sole 5 is fixed to the bottom of the upper unit 1.
[0003] If Figure 4 、 5 As shown in FIG. 1 , the upper unit 1 is formed by sewing an upper cut piece 101. The shoe-shaped inner cover unit 2 is formed by sewing a moisture-permeable and waterproof inner cover cut piece 201, and a plurality of waterproof strips 202 are attached to the sewing part of the inner cover cut piece 201.
[0004] Although this kind of breathable and waterproof shoes can provide users with better wearing coverage, they have the following deficiencies in actual manufacturing:
[0005] 1. Since the upper piece 101 and the inner cover piece 201 need to be sewn into the upper unit 1 and the shoe-shaped inner cover unit 2 respectively during the manufacture of this type of breathable waterproof shoe, this type of breathable waterproof shoe needs to be sewn twice independently. Moreover, since the upper piece 101 and the inner cover piece 201 are not in the same shape, the sewing process of these two independent sewing operations cannot be unified, making the sewing operation of this type of breathable waterproof shoe quite troublesome.
[0006] Second, after the sewing operation of the upper unit 1 and the shoe-shaped inner cover unit 2 is completed, an adhesive needs to be sprayed on the inner surface of the upper unit 1, and then the shoe-shaped inner cover unit 2 and the upper unit 1 can be successively put on a shoe last (not shown) so that the shoe-shaped inner cover unit 2 and the upper unit 1 are combined together through the adhesive layer 3 formed by the adhesive, which is quite troublesome in the process.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0040] Refer to Figure 6 、 7 For an embodiment of a moisture-permeable and waterproof shoe 100 with synchronous sealing of the upper and the shoe cover according to the present invention, the moisture-permeable and waterproof shoe 100 includes a composite structure 10 of the upper and the shoe cover, a sole unit 20, and a strengthening unit 30.
[0041] The composite structure 10 of the upper and the shoe cover includes a shoe-shaped composite body 40 defining a wearing space 47 with an open top and a closed bottom, a sewing unit 50 provided on the shoe-shaped composite body 40, and a waterproof unit 60 provided on the shoe-shaped composite body 40.
[0042] As shown in Figure 8 、 9 、10, the shoe-shaped composite body 40 is made of a composite sheet 41, the composite sheet 41 includes an upper cut piece 42, a shoe cover cut piece 43 located inside the upper cut piece 42 and having a shape corresponding to that of the upper cut piece 42, and an adhesive 44 fixed between the upper cut piece 42 and the shoe cover cut piece 43.
[0043] In this embodiment, the shapes of the upper cut piece 42 and the shoe cover cut piece 43 are substantially the same, however, this is not limiting. In addition, the upper cut piece 42 and the shoe cover cut piece 43 are bonded together by vacuum thermoforming, however, this is not limiting.
[0044] In this embodiment, the upper cut piece 42 is treated with water repellency and thus has water repellency.
[0045] The shoe cover cut piece 43 can be waterproof and breathable. In this embodiment, the shoe cover cut piece 43 includes a lining layer 431, a surface layer 432, an upright fleece layer 433 woven between the lining layer 431 and the surface layer 432, a moisture-permeable waterproof layer 434 located outside the surface layer 432, and an adhesive layer 435 fixed between the surface layer 432 and the moisture-permeable waterproof layer 434. The upright fleece layer 433 has several mutually spaced fleece yarns 436.
[0046] As shown in Figure 9 、 11As shown, the composite sheet 41 has a main face 45, and two wing portions 46 symmetrically disposed on both sides of the main face 45 and integrally connected to the main face 45.
[0047] The main face 45 has a front outward convex arc edge 451, two mutually symmetric rear end docking edges 452, a rear inward concave edge 453 connected between the rear end docking edges 452 and opposite to the front outward convex arc edge 451, and two mutually symmetric rear connecting edges 454 respectively connected to the rear end docking edges 452.
[0048] Each wing portion 46 has a side docking edge 461, a front arc edge 462 connected between the side docking edge 461 and the front outward convex arc edge 451, and a rear arc edge 463 connected between the side docking edge 461 and the corresponding rear connecting edge 454. The side docking edge 461 of each wing portion 46 is connected to the corresponding rear end docking edge 452 via the rear arc edge 463 and the corresponding rear connecting edge 454.
[0049] As Figure 11 、 12 shown, the sewing unit 50 sews the composite sheet 41 into the shoe-shaped composite body 40 and has water repellency. The sewing unit 50 includes a toe sewing portion 51 adjacent to the front end of the shoe-shaped composite body 40, a heel sewing portion 52 adjacent to the rear end of the shoe-shaped composite body 40, a sole sewing portion 53 located on the bottom side of the shoe-shaped composite body 40, and a rear end sewing portion 54 adjacent to the rear end of the shoe-shaped composite body 40. It can be understood that when the composite sheet 41 is sewn into the shoe-shaped composite body 40, the shoe-shaped composite body 40 will include a three-dimensional shoe upper 48 formed by the shoe upper cut piece 42, and a three-dimensional shoe cover 49 formed by the shoe cover cut piece 43.
[0050] The toe sewing portion 51 sews the front arc edges 462 of the wing portions 46 and the front outward convex arc edge 451 together along the front arc edges 462 of the mutually butted wing portions 46 and the front outward convex arc edge 451.
[0051] The heel sewing portion 52 sews the rear arc edges 463 of the wing portions 46 and the rear connecting edges 454 together along the rear arc edges 463 of the mutually butted wing portions 46 and the rear connecting edges 454.
[0052] The sole sewing portion 53 sews the side docking edges 461 of the wing portions 46 together along the side docking edges 461 of the mutually butted wing portions 46.
[0053] The rear end sewing portion 54 sews the rear end docking edges 452 together along the mutually butted rear end docking edges 452.
[0054] In this embodiment, the toe sewing part 51, the sole sewing part 53, the rear sewing part 54 and the heel sewing part 52 of the sewing unit 50 are all sewing threads with water-repellent properties after water-repellent treatment.
[0055] In this embodiment, the upper cut piece 42 and the shoe cover cut piece 43 are represented by substantially the same outer contour shape. However, this is not limited thereto. For example, since the upper cut piece 42 and the shoe cover cut piece 43 do not need to be sewn and aligned with each other at the rear inner concave edge 453 of the main surface part 45 of the composite sheet 41, the contours of the upper cut piece 42 and the shoe cover cut piece 43 at the rear inner concave edge 453 do not need to be completely consistent. For example, the contour of the upper cut piece 42 at the rear inner concave edge 453 can be pushed further inward to cover the contour of the shoe cover cut piece 43 at the rear inner concave edge 453.
[0056] As Figure 12 , 13 shown, the waterproof unit 60 is fixedly connected to the outer surface of the shoe-shaped composite body 40 and covers the toe sewing part 51, the heel sewing part 52, the sole sewing part 53 and the rear sewing part 54.
[0057] In this embodiment, the waterproof unit 60 has a first waterproof strip 61, two second waterproof strips 62, and two third waterproof strips 63. The first waterproof strip 61 is fixedly connected to the outer surface of the shoe upper piece 42 along the rear docking edge 452 of the main face portion 45 and the side docking edge 461 of the wing portion 46 to cover the rear docking edge 452 of the main face portion 45 and the side docking edge 461 of the wing portion 46. The first waterproof strip 61 also covers the rear sewing portion 54 and the sole sewing portion 53. One of the second waterproof strips 62 is fixedly connected to the outer surface of the shoe upper piece 42 along the front arc edge 462 of one of the wing portions 46 and the front outward convex arc edge 451 to cover the front arc edge 462 of the one wing portion 46 and the front outward convex arc edge 451, and intersects with the first waterproof strip 61. The other second waterproof strip 62 is fixedly connected to the outer surface of the shoe upper piece 42 along the front arc edge 462 of the other wing portion 46 and the front outward convex arc edge 451 to cover the front arc edge 462 of the other wing portion 46 and the front outward convex arc edge 451, and intersects with the first waterproof strip 61. The second waterproof strips 62 also cover the toe sewing portion 51. One of the third waterproof strips 63 is fixedly connected to the outer surface of the shoe upper piece 42 along the rear arc edge 463 of one of the wing portions 46 and one of the rear connecting edges 454 to cover the rear arc edge 463 of the one wing portion 46 and the one rear connecting edge 454, and intersects with the first waterproof strip 61. The other third waterproof strip 63 is fixedly connected to the outer surface of the shoe upper piece 42 along the rear arc edge 463 of the other wing portion 46 and the other rear connecting edge 454 to cover the rear arc edge 463 of the other wing portion 46 and the other rear connecting edge 454, and intersects with the first waterproof strip 61. The third waterproof strips 63 also cover the heel sewing portion 52.
[0058] As Figure 15 、 18 shown, the first waterproof strip 61 of the waterproof unit 60 has an exposed portion 611 corresponding to the rear docking edge 452 of the main face portion 45 and located outside the sole unit 20.
[0059] As Figure 16 、 17 shown, the sole unit 20 is fixedly provided at the bottom of the shoe upper shoe cover composite structure 10.
[0060] As Figure 13 、 14 、15 shown, the strengthening unit 30 is fixedly provided on the shoe upper shoe cover composite structure 10 to cover the portion of the waterproof unit 60 corresponding to the rear sewing portion 54 and located outside the sole unit 20.
[0061] As Figure 15 、 18As shown, in this embodiment, the reinforcement unit 30 is a TPU sheet. The reinforcement unit 30 is fixed to the upper shoe cover composite structure 10 by high-frequency welding and covers the exposed part 611 of the first waterproof strip 61. In addition, it should be noted that, of course, hot melt adhesive can also be coated on the inner side of the reinforcement unit 30, and then by high-frequency welding, the hot melt adhesive is fixedly connected between the reinforcement unit 30 and the upper shoe cover composite structure 10.
[0062] As Figure 8 - 16 shown, the manufacturing method of the moisture-permeable and waterproof shoe 100 is briefly described as follows, however, it is not limited thereto:
[0063] I. As Figure 8 、 9 、10 shown, the upper cut piece 42 and the shoe cover cut piece 43 are bonded together by vacuum thermoforming to form the composite sheet 41.
[0064] II. As Figure 11 、 12 shown, the composite sheet 41 is sewn into the shoe-shaped composite body 40.
[0065] III. As Figure 12 、 13 shown, the first waterproof strip 61, the second waterproof strip 62 and the third waterproof strip 63 are attached to the sewing part of the shoe-shaped composite body 40 to cover the sewing part of the shoe-shaped composite body 40.
[0066] IV. As Figure 13 、 14 、15 shown, the reinforcement unit 30 is fixed to the rear end of the upper shoe cover composite structure 10 to cover the exposed part 611 of the first waterproof strip 61.
[0067] V. As Figure 16 shown, the sole unit 20 is fixedly adhered to the bottom of the upper shoe cover composite structure 10.
[0068] Through the above description, the advantages of the present invention can be summarized as follows:
[0069] I. The upper shoe cover composite structure 10 of the present invention uses the design of pre-bonding the upper cut piece 42 and the shoe cover cut piece 43 into the composite sheet 41. The present invention only needs to perform one sewing operation to sew the composite sheet 41 into the shoe-shaped composite body 40. That is to say, the present invention only needs to perform one sewing operation to synchronously seal the three-dimensional upper 48 and the three-dimensional shoe cover 49 of the shoe-shaped composite body 40. Compared with the prior art, the present invention can effectively simplify the number and process of sewing operations required.
[0070] II. In the composite structure 10 of the shoe upper and shoe cover of the present invention, the design is such that the shoe upper cut piece 42 and the shoe cover cut piece 43 are pre-bonded into the composite sheet 41 by the adhesive 44. When the composite sheet 41 is sewn into the shoe-shaped composite body 40 in the present invention, the sewing operation and the bonding operation of the three-dimensional shoe upper 48 and the three-dimensional shoe cover 49 of the shoe-shaped composite body 40 are simultaneously completed. Compared with the prior art, the present invention can omit the adhesive spraying operation of the prior art, simplify the overall manufacturing process, and reduce the environmental problems caused by the volatilization of the adhesive.
[0071] III. In this case, the design that the shoe upper cut piece 42 has water repellency and the sewing unit 50 has water repellency can effectively prevent external moisture from infiltrating into the interior of the shoe-shaped composite body 40 from the stitches of the sewing unit 50 due to the siphon effect at the places other than the parts of the shoe-shaped composite body 40 covered by the waterproof unit 60.
[0072] IV. In this case, the design that the strengthening unit 30 covers the exposed part 611 of the first waterproof strip 61 can strengthen the bonding property between the exposed part 611 of the first waterproof strip 61 and the shoe-shaped composite body 40 and the waterproof property of the exposed part 611 of the first waterproof strip 61.
[0073] In summary, the moisture-permeable and waterproof shoe with synchronous sealing of the shoe upper and shoe cover of the present invention can not only effectively simplify the number and process of the sewing operation required, simplify the overall manufacturing process, but also effectively prevent external moisture from infiltrating into the interior of the shoe-shaped composite body from the stitches of the sewing unit due to the siphon effect. Therefore, it can indeed achieve the purpose of the present invention.
[0074] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope of the present invention.
