Method for manufacturing valgus shoes

The present invention relates to a method of manufacturing a shoe, and more particularly to a method of manufacturing an outwardly turned shoe.

Referring to Figure 1, a known eversion shoe includes a sole 11 and an upper 12. The sole 11 includes a large bottom layer 111 for contacting the ground, and a middle bottom layer 112 correspondingly bonded to the large bottom layer 111. The upper 12 is secured over the sole 111 and cooperates with the sole 11 to define a foot space 10 for the user's foot to extend into. The eversion shoe is characterized in that the upper 12 and the middle bottom layer 112 are everted, and the upper edge of the upper 12 is stitched and fixed to the periphery of the middle bottom layer 12 by a stitch 13 which extends along the circumference of the upper 12. It forms a good-looking appearance, so the valgus shoes are one of the favorite shoes for many people.

In the conventional manner of manufacturing the eversion shoe, the upper 12 is first fixed to the midsole 112, and the middle layer 112 that has been bonded to the upper 12 is bonded and fixed to the large bottom layer 111. Wherein, the suture fixation is manually stitched by a flat stitch method, and the whole needle must be continuously and repeatedly passed through the upper 12 and the middle bottom layer 112 from the top to the bottom during the flat stitching process. Then, the middle bottom layer 112 and the upper 12 are passed from bottom to top. However, the repeated upward and downward stitching is repeated, which causes the manufacturing of the valgus shoe to be time-consuming and labor-intensive, so that it is known outside. The method of turning shoes has to be improved.

Accordingly, it is an object of the present invention to provide a method of manufacturing an everted shoe that is simple in steps, convenient to carry out, and quick.

Thus, the method of manufacturing the everted shoe of the present invention is suitable for use with a crochet for engaging a suture, the crochet comprising a grip portion, and a hook segment connected to one end of the grip portion for pulling the suture The method for manufacturing the everted shoe comprises the step A: combining a middle bottom layer with a large bottom layer, the middle bottom layer having a midsole body corresponding to the large bottom layer, and a bottomed body surrounding the midsole body a midsole circumference; step B: suturing an upper layer over the middle layer, the upper layer having a top of the upper for engaging the periphery of the midsole, the step is to match the stitch with the crochet The peripheral edge of the upper is stitched to the periphery of the midsole. During the suturing process, the hook segment extends through the periphery of the upper and the periphery of the midsole, and the grip portion does not extend through the periphery of the upper. The midsole periphery.

The invention has the effect that the invention changes the manufacturing sequence of the known manufacturing method, and the middle bottom layer is first fixed on the large bottom layer, and the large bottom layer is used to bear the force of the crochet stitching process, so that the hook portion of the crochet needle can be easily applied. Pass through the midsole and the upper layer. It is also because of the support of the large bottom layer that the present invention can be stitched using crochet, thereby making the manufacturing process simpler, more convenient and faster.

Referring to Figures 2, 3, 4, and 5, a method of manufacturing the swelled shoe 2 of the present invention is for making the swelled shoe 2, the swelled shoe 2 includes a large bottom layer 21 for contacting the ground, and a affixed to the large a midsole layer 22 above the bottom layer 21, and an upper layer 23 stitched to the upper bottom layer 22, the upper layer 23 cooperating with the midsole layer 22 to define a foot space for the user's foot to extend into 20. The manufacturing method of the present embodiment is suitable for use with a crochet 3 for engaging a suture 4, the crochet 3 including a grip portion 31, and a hook portion 32 connected to one end of the grip portion 31. The grip segment 31 is radially enlarged relative to the hook segment 32 to facilitate hand grip and force application. The hook section 32 has a needle 321 at one end and is hook-shaped, and the needle 321 can pull the suture 4 by hooking.

Referring to Figures 4, 5, 6, the manufacturing method comprises the following steps:

Step 51: Combining the middle bottom layer 22 with the large bottom layer 21 by means of, for example, pasting, the middle bottom layer 22 has a midsole body 221 bonded to the large bottom layer 21, and a middle base A midsole periphery 222 around the body 221. The midsole periphery 222 is formed with a plurality of intervals, and a first perforation 223 is arranged in a circle along its outer peripheral contour. When the middle bottom layer 22 is bonded to the large bottom layer 21, the midsole periphery 223 slightly protrudes beyond the large bottom layer 21 to facilitate the subsequent stitching step.

Step 52: The upper layer 23 is stitched and fixed above the middle bottom layer 22. The upper layer 23 has an upper body 231, and an upper periphery 232 connected to the upper of the upper body 231. The upper periphery 232 is formed with a plurality of second through holes 233 corresponding to the first through holes 223, respectively. . The second through hole 233 and the first through hole 223 can pass through the hook portion 32 of the crochet 3 to pull the stitch 4 so that the stitch 4 can be sewn and the midsole periphery 222 and the upper edge of the upper 232 fixed.

Specifically, when step 52 is performed, the suture 4 is first placed on the upper layer 23, and when the needle is taken up, the crochet 3 is passed from bottom to top through one of the corresponding first perforations 223 and one of them. The second through hole 233 is further hooked downwardly through the second through hole 233 and the first through hole 223. At this time, the stitch 4 is connected and located under the middle bottom layer 22 and the upper layer 23 respectively. A first line segment 41 and a second line segment 42 are disposed above. Next, at the next first through hole 223 and the second through hole 233, the hook portion 32 of the crochet 3 is sequentially passed through the midsole periphery 222 and the upper periphery 232 from bottom to top, and the second line segment 42 is further Partially downwardly and sequentially through the upper perimeter 232 and the midsole perimeter 222, the second line segment 42 further defines an annular space 420 below the midsole perimeter 222. The first line segment 41 is continuously stretched through the annular space 420 (hereinafter referred to as the threading step), and the second line segment 42 is tightened in the direction indicated by the arrow A in FIG. 6 (hereinafter referred to as the tightening step), so that the second line segment The line segment 42 and the first line segment 41 are closely attached to the midsole periphery 222 and the upper edge 232 of the upper. Then, at the next corresponding first through hole 223 and the second through hole 233, the second line segment 42 is partially pulled down to form an annular space 420, and the threading step and the tightening step are repeated, and the step repeating number is repeated. After that, the production of the eversion shoe 2 is completed until the entire midsole periphery 222 is stitched and secured to the upper periphery 232.

It should be noted that, because the crochet 3 is used for stitching, an object having a certain hardness is supported as a support, which is more convenient for the stitching step, and the present invention first couples the middle bottom layer 22 to the large bottom layer 21, and the large bottom layer 21 has a certain The hardness of the material can be used as a basis for the force in the stitching step to withstand the force of the needle 321 of the crochet 3 as it passes through the midsole periphery 222 and the upper edge 232 of the upper. The hole design of the second through hole 233 and the first through hole 223 is preset, so that the needle 321 of the hook portion 32 passes through the midsole periphery 222 and the upper edge 232 of the upper surface, and the hole is preset. The spacing is such that the stitches formed after stitching 4 are substantially the same length and beautifully arranged.

Moreover, during the suture fixation process, the grip segment 31 does not extend through the upper edge 232 of the upper and the peripheral edge 222 of the midsole, and only the needle 321 of the crochet 3 needs to pass through the peripheral edge 232 of the upper. The midsole periphery 222, that is, the portion of the crochet 3 that needs to pass through the upper periphery 232 and the midsole periphery 222 is small, and the entire needle must pass through the suture of the shoe relative to the conventional flat stitch. In other words, the crochet portion 3 of the present invention has a small puncture site, which makes the operator less laborious when suturing, and the action amplitude can also be small, which facilitates the rapid repetitive suturing step, so the suturing process is relatively simple and rapid, and the production time can be shortened.

In summary, the present invention changes the manufacturing sequence of the known manufacturing method. First, the middle bottom layer 22 is fixed on the large bottom layer 21, and the large bottom layer 21 is used to bear the force of the crochet stitching process, so that the operator can easily apply force. The needle 321 of the crochet 3 is passed through the midsole 22 and the upper layer 23. Because of the support of the large bottom layer 21, the crochet 3 can be used for sewing according to the present invention. Compared with the conventional flat stitch, the method of the present invention is simplified, and the manufacturing process is convenient and rapid.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
