Abstract
Description
Technical Field
[0001] This invention relates to a shoe, and more particularly to a method for manufacturing a breathable and waterproof shoe that prevents slipping off the foot and is easy to wear. Background Technology
[0002] like Figure 1 , 2 As shown, existing knitted sock shoes generally include a 3D sock-shaped knitted upper 1, a shoe-shaped inner sleeve 2 fixed inside the 3D sock-shaped knitted upper 1 and having an opening 201, and a sole 3 fixed to the bottom side of the 3D sock-shaped knitted upper 1.
[0003] The 3D sock-like knitted upper 1 is generally made of elastic yarn. Although the 3D sock-like knitted upper 1 with good overall elasticity can provide good coverage for the user's feet, it lacks restraint because the 3D sock-like knitted upper 1 is elastic in the front-back direction and the left-right direction of the insertion opening 201 of the shoe-like inner sleeve 2. Therefore, during the wearing activity, the user's feet may sometimes accidentally slip out of the insertion opening 201 of the shoe-like inner sleeve 2. Summary of the Invention
[0004] The purpose of this invention is to provide a method for manufacturing breathable and waterproof shoes that can overcome at least one of the disadvantages of prior art, making them slip-proof and easy to wear.
[0005] The present invention provides a method for manufacturing breathable and waterproof shoes that are slip-resistant and easy to wear, comprising:
[0006] (A) Prepare a shoe upper piece and a binding strip. The shoe upper piece has an open concave edge and two rear end mating edges. The open concave edge is connected between the rear end mating edges. The binding strip is sewn along the open concave edge to the shoe upper piece and covers the open concave edge.
[0007] (B) The tongue piece is sewn along the opening recess to the upper piece and the binding strip. The tongue piece has a loop portion and a tongue-shaped portion protruding forward from the loop portion. The loop portion has a shoe opening perimeter, a front connecting edge opposite to the shoe opening perimeter, and two side edges connecting the front connecting edge and the shoe opening perimeter. The side edges correspond to the rear end mating edge. The tongue-shaped portion protrudes forward from the front connecting edge and has a tongue-shaped perimeter. The front connecting edge and the tongue-shaped perimeter are located inside the upper piece. The tongue piece is made of an elastic material and has greater elasticity than the upper piece.
[0008] (C) The rear end edges of the shoe upper pieces are joined together and sewn together, and the side edges of the loop portion are joined together and sewn together.
[0009] (D) Turn the shoe upper piece and the shoe tongue piece out from the inside out.
[0010] (E) Prepare a breathable and waterproof shoe-shaped inner sleeve, the shoe-shaped inner sleeve defining a wearing space with an open top and a closed bottom, the shoe-shaped inner sleeve including a top connecting end, the top connecting end being sewn to the loop portion of the shoe tongue block, so that the periphery of the shoe opening of the loop portion is located within the wearing space.
[0011] (F) Fold the upper piece and the tongue piece back from the outside to the inside relative to the shoe-shaped inner sleeve, so that the top connecting end of the shoe-shaped inner sleeve is folded back to be outside the wearing space, and the shoe-shaped inner sleeve is located inside the upper piece and the tongue piece.
[0012] (G) The upper piece is sewn closed opposite to the bottom of the tongue block, so that the upper piece and the tongue block define an internal space with an open top and a closed bottom. The internal space forms an inlet surrounded by the loop portion, and the wearing space of the shoe-shaped inner sleeve forms an entrance that communicates with the inlet.
[0013] (H) Insert the shoe last into the wearing space of the shoe-shaped inner sleeve.
[0014] (I) Secure the sole to the bottom of the upper piece.
[0015] The present invention provides a breathable and waterproof shoe manufacturing method that prevents slipping and is easy to wear, and further includes a step (C1) between step (B) and step (C), in which two eyelet pieces are sewn to the upper piece and located on both sides of the tongue-shaped portion of the tongue piece, each eyelet piece having several shoelace holes.
[0016] The present invention provides a breathable and waterproof shoe manufacturing method that prevents slipping and is easy to wear, further comprising a step (D1) between step (C) and step (D), in which a heel pull strap is temporarily positioned on the upper piece, the heel pull strap corresponding to the rear end joint edge of the upper piece.
[0017] The present invention provides a method for manufacturing breathable and waterproof shoes that prevent slippage and are easy to wear. In step (C), the binding strip is arranged around the ankle opening and the instep notch communicating with the ankle opening along the concave edge of the opening. The loop portion covers the ankle opening, and the tongue portion closes the instep notch. In step (D), the front connecting edge of the loop portion and the peripheral edge of the tongue portion are located outside the upper piece. Step (F) includes a sub-step (F1), a step (F2) after the sub-step (F1), a step (F3) after the sub-step (F2), a step (F4) after the sub-step (F3), and a step (F5) after the sub-step (F4). In sub-step (F1), the upper piece and the shoe... In step F2, the shoe-shaped inner sleeve is folded back from the outside to the inside relative to the shoe upper piece and the shoe tongue. In step F3, the heel pull tab is folded in half and sewn onto the loop portion of the shoe tongue and the shoe upper piece, with the heel pull tab corresponding to the side edge and the rear end joint edge. In step F4, the heel reinforcement piece is sewn onto the shoe upper piece, with the heel reinforcement piece symmetrical to the rear end joint edge. In step F5, the shoe-shaped inner sleeve is folded back from the outside to the inside relative to the shoe upper piece and the shoe tongue until the shoe-shaped inner sleeve is located inside the shoe upper piece and the shoe tongue, so that the top connecting end of the shoe-shaped inner sleeve is folded back to be outside the wearing space.
[0018] The present invention provides a method for manufacturing breathable and waterproof shoes that prevent slipping and are easy to wear, further comprising a step (I1) between step (H) and step (I). In step (E), the shoe-shaped inner sleeve has a breathable and waterproof layer and an adhesive layer coated on the outside of the breathable and waterproof layer. In step (I1), heating is performed to fix the adhesive layer between the shoe upper piece and the shoe-shaped inner sleeve, and between the shoe tongue piece and the shoe-shaped inner sleeve.
[0019] The present invention provides a breathable and waterproof shoe manufacturing method that prevents slipping and is easy to wear. It also includes a step (I2) between step (I1) and step (I), in which the sole is bonded to the bottom of the upper piece using an adhesive. In step (I), heating is performed to fix the sole to the bottom of the upper piece.
[0020] The present invention discloses a method for manufacturing breathable and waterproof shoes that prevent slipping and are easy to wear. In step (A), the upper piece includes a main face and two symmetrically arranged side wings integrally connected to the main face. The main face has a front outward convex arc edge, an opening concave edge opposite to the front outward convex arc edge, mutually symmetrical rear end mating edges, and two mutually symmetrical rear connecting edges connected to the rear end mating edges respectively. Each side wing has a side mating edge, a front arc-shaped edge connecting the side mating edge and the front outward convex arc edge, and a rear arc-shaped edge connecting the side mating edge and its respective rear connecting edge. In step (G), the side mating edges of the side wings are mated together and sewn together, the rear arc-shaped edges of the side wings are mated together and sewn together with the rear connecting edges respectively, and the front arc-shaped edges of the side wings are mated together and sewn together with the front outward convex arc edge. The front connecting edge of the loop portion and the tongue-shaped periphery of the tongue portion are lower than the opening concave edge.
[0021] The present invention provides a breathable and waterproof shoe manufacturing method that prevents slipping and is easy to wear. In the sub-step (F3), the heel pull tab is sewn to the loop portion of the shoe tongue block and the main surface of the shoe upper piece. In the step (F4), the heel reinforcement piece is sewn to the main surface of the shoe upper piece.
[0022] The present invention provides a method for manufacturing breathable and waterproof shoes that are slip-resistant and easy to wear. In step (E), the shoe-shaped inner sleeve further comprises a lining layer, an outer fabric layer, and a support layer disposed between the lining layer and the outer fabric layer. The breathable and waterproof layer is fixed to the outer surface of the outer fabric layer. The shoe-shaped inner sleeve is made by sewing together a single inner sleeve piece. Several waterproof strips are fixed to the outer surface of the breathable and waterproof layer to cover the seams of the shoe-shaped inner sleeve. The adhesive layer is applied to the outer side of the breathable and waterproof layer and the outer side of the waterproof strips.
[0023] The present invention provides a method for manufacturing breathable and waterproof shoes that are easy to wear and prevent slipping. In step (A), the material of the upper piece is a non-elastic mesh fabric, and in step (B), the material of the tongue piece is elastic yarn, and the tongue piece has water-repellent properties.
[0024] The beneficial effects of this invention are as follows: This invention utilizes a design where the shoe tongue block has greater elasticity than the upper panel. The shoe tongue block maintains elasticity in the front-to-back direction of the entry point in the shoe-like inner sleeve's wearing space, while the upper panel provides restraint in the left-to-right direction. Thus, when the user wears the breathable and waterproof shoes manufactured according to this invention, they can use both hands to pull open the loop portion of the shoe tongue block, widening the opening width in the front-to-back direction and increasing the entry angle, making it easier for the user to put their foot into the shoe. As the foot enters the shoe-shaped inner sleeve through the inlet of the upper unit, the elasticity of the tongue-shaped portion of the shoe tongue makes it easier for the user to completely slip the foot into the shoe-shaped inner sleeve's wearing space. Subsequently, the upper piece, with less elasticity than the tongue, provides lateral restraint to the user's foot at the entrance of the shoe-shaped inner sleeve's wearing space, preventing the foot from accidentally slipping out during wear. The breathable and waterproof shoes manufactured by this invention are not only easy to put on but also prevent accidental slippage. Furthermore, the top connecting end of the shoe-shaped inner sleeve of the breathable and waterproof shoes manufactured by this invention is folded back outside the wearing space and sewn onto the loop portion of the tongue. From the inside, this stitching is hidden between the shoe-shaped inner sleeve and the tongue, thus simplifying the stitching marks inside the breathable and waterproof shoes, increasing texture, and effectively preventing wear and tear on the stitching during wear.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0049] See Figure 3 This is an embodiment of the present invention's method for manufacturing breathable and waterproof shoes that prevent slipping and are easy to wear, such as... Figure 22 , 23 As shown, a breathable and waterproof shoe 100 manufactured by this breathable and waterproof shoe manufacturing method includes an upper unit 10, a shoe-shaped inner sleeve unit 20, a sole 30, and an adhesive layer 40 (see...). Figure 20The upper unit 10 includes an upper piece 11, a piping strip 12, a tongue piece 13, two eyelet pieces 14, a shoelace 15, a heel pull tab 16, a reinforcing strip 161, and a heel reinforcing piece 17. The shoe-shaped inner sleeve unit 20 is disposed inside the upper unit 10 and includes a shoe-shaped inner sleeve 21 and a waterproof assembly 22, which has several waterproof strips 221.
[0050] This breathable and waterproof shoe manufacturing method includes the following steps:
[0051] Step 200 (see) Figure 3 ):like Figure 4 , 5 As shown, prepare the shoe upper piece 11 and the piping strip 12, and sew the piping strip 12 onto the shoe upper piece 11.
[0052] In this embodiment, the shoe upper piece 11 includes a main face 18 and two symmetrically arranged side wings 19 on both sides of the main face 18 and integrally connected to the main face 18. The main face 18 has a front outward convex arc edge 181, an open concave edge 182 opposite to the front outward convex arc edge 181, two mutually symmetrical rear end mating edges 183, and two mutually symmetrical rear connecting edges 184 respectively connected to the rear end mating edges 183. The open concave edge 182 is connected between the rear end mating edges 183. Each side wing 19 has a side edge mating edge 191, a front arc-shaped edge 192 connecting the side edge mating edge 191 and the front outward convex arc edge 181, and a rear arc-shaped edge 193 connecting the side edge mating edge 191 and its respective rear connecting edge 184. The shoe upper piece 11 is made of non-elastic mesh fabric and has water-repellent properties.
[0053] In this embodiment, a sewing thread 121 is used to sew the piping strip 12 along the opening recess 182 onto the shoe upper piece 11 and to cover the opening recess 182.
[0054] Step 210 (see) Figure 3 ):like Figure 4 , 6 As shown, the tongue piece 13 is sewn along the opening recess 182 onto the upper piece 11 and the piping strip 12.
[0055] The shoe tongue block 13 has a loop portion 131 and a tongue-shaped portion 132 protruding forward from the loop portion 131. The shoe tongue block 13 is made of elastic material and has water-repellent properties. The shoe tongue block 13 has greater elasticity than the upper panel 11. In this embodiment, the material of the shoe tongue block 13 is elastic yarn.
[0056] The loop portion 131 has a shoe opening perimeter 133, a front connecting edge 134 opposite to the shoe opening perimeter 133, and two side edges 135 connecting the front connecting edge 134 and the shoe opening perimeter 133. The side edges 135 correspond to the rear abutment edge 183 respectively. The tongue portion 132 protrudes forward from the front connecting edge 134 and has a tongue-shaped perimeter 136.
[0057] In this embodiment, the tongue piece 13 is sewn onto the upper piece 11 and the piping strip 12 using a sewing thread 137, so that the front connecting edge 134 and the tongue-shaped periphery 136 are located on the inside of the upper piece 11.
[0058] Step 220 (see) Figure 3 ):like Figure 4 , 7 As shown, the eyelet piece 14 is sewn onto the upper piece 11 and located on both sides of the tongue-shaped portion 132 of the tongue block 13. Each eyelet piece 14 has several shoelace holes 141.
[0059] Step 230 (see) Figure 3 ):like Figure 7 , 8 As shown, the rear end edges 183 of the main face 18 of the shoe upper piece 11 are joined together and sewn together, and the side edges 135 of the loop portion 131 of the shoe tongue piece 13 are joined together and sewn together, so that the piping strip 12 runs along the opening recess 182 (see Figure 4 The ankle opening 185 is formed around the instep notch 186, which is connected to the ankle opening 185. At this time, the ring portion 131 covers the ankle opening 185, and the tongue portion 132 closes the instep notch 186.
[0060] In this embodiment, the side edge 135 and the rear abutment edge 183 are sewn together using the same stitching thread.
[0061] Step 240 (see) Figure 3 ):like Figure 4 , 9 As shown, the heel pull strap 16 is temporarily positioned on the main face 18 of the upper piece 11, and the heel pull strap 16 corresponds to the rear end joint edge 183 of the main face 18 of the upper piece 11.
[0062] In this embodiment, the reinforcing strip 161 is first sewn along the side edge 135 of the loop portion 131 of the shoe tongue block 13 to cover the side edge 135. Then, the heel pull strap 16 is temporarily attached to the heel of the main surface 18 of the upper piece 11 using double-sided tape.
[0063] Step 250 (see) Figure 3 ):like Figure 9 , 10 As shown, the shoe upper piece 11 and the shoe tongue piece 13 are turned outward from the inside, so that the front connecting edge 134 of the loop portion 131 and the tongue-shaped periphery 136 of the tongue portion 132 are located on the outside of the shoe upper piece 11.
[0064] Step 260 (see) Figure 3 ):like Figure 11 , 12 As shown, a breathable and waterproof shoe-shaped inner sleeve 21 is prepared. The shoe-shaped inner sleeve 21 defines a wearing space 24 that is open at the top and closed at the bottom. The shoe-shaped inner sleeve 21 includes a top connecting end 211, which is sewn onto the loop portion 131 of the shoe tongue block 13. The shoe opening periphery 133 of the loop portion 131 is located within the wearing space 24, surrounding the loop portion 131. In this embodiment, the top connecting end 211 is sewn onto the loop portion 131 of the shoe tongue block 13 using a sewing thread 25.
[0065] In this embodiment, as Figure 19 , 20 As shown, the shoe-shaped inner sleeve 21 has a lining layer 212, an outer fabric layer 213, a support layer 214 disposed between the lining layer 212 and the outer fabric layer 213, a breathable and waterproof layer 215 fixed to the outer surface of the outer fabric layer 213, and an adhesive layer 216. The support layer 214 is a vertical pile layer woven between the lining layer 212 and the outer fabric layer 213, but it is not limited to this. In other variations, the support layer 214 can also be a foam layer. The adhesive layer 216 is made of hot melt adhesive.
[0066] In this embodiment, the shoe-shaped inner sleeve 21 is made by sewing together an inner sleeve piece 23. The waterproof strip 221 is fixed to the outer surface of the breathable waterproof layer 215 to cover the seams of the shoe-shaped inner sleeve 21. The adhesive layer 216 is applied to the outer side of the breathable waterproof layer 215 and the outer side of the waterproof strip 221.
[0067] Step 270 (see) Figure 3 ):like Figure 11 , 13 As shown, the shoe upper piece 11 and the shoe tongue piece 13 are folded back from the outside to the inside relative to the shoe-shaped inner sleeve 21.
[0068] Step 280 (see) Figure 3 In ) such as Figure 11 , 13 As shown, the shoe-shaped inner sleeve 21 is turned outwards relative to the upper piece 11 and the tongue piece 13, so that most of the shoe-shaped inner sleeve 21 is outside the upper piece 11 and the tongue piece 13.
[0069] Step 290 (see) Figure 3 ):like Figure 13 As shown, the heel pull tab 16 is folded in half and sewn onto the loop portion 131 of the tongue block 13 and the main surface portion 18 of the upper piece 11. The heel pull tab 16 corresponds to the side edge 135 (see...). Figure 9 ) and the rear end mating edge 183 (see Figure 9 ).
[0070] Step 300 (see) Figure 3 ):like Figure 14 As shown, the heel reinforcement piece 17 is sewn onto the main surface 18 of the upper piece 11, and the heel reinforcement piece 17 is symmetrical to the rear end mating edge 183 (see...). Figure 9 ).
[0071] Step 310 (see) Figure 3 ):like Figure 14 , 15 As shown in Figure 16, the shoe-shaped inner sleeve 21 is folded back from the outside to the inside relative to the upper piece 11 and the tongue piece 13, so that the shoe-shaped inner sleeve 21 is located inside the upper piece 11 and the tongue piece 13, and the top connecting end 211 of the shoe-shaped inner sleeve 21 is folded back to be located outside the wearing space 24.
[0072] Step 320 (see) Figure 3 ):like Figure 17 , 18 As shown in Figure 19, the shoe upper piece 11 is sewn closed at the bottom opposite to the shoe tongue piece 13, so that the shoe upper piece 11 and the shoe tongue piece 13 cooperate to define an internal space 50 with an open top and a closed bottom. The internal space 50 forms an inlet 51 surrounded by the loop portion 131. The wearing space 24 of the shoe-shaped inner sleeve 21 forms an entrance 241 that communicates with the inlet 51. At this time, the front connecting edge 134 of the loop portion 131 of the shoe tongue piece 13 and the tongue-shaped periphery 136 of the tongue portion 132 are located inside the shoe upper piece 11 and are lower than the opening recess 182 (see Figure 19). Figure 19 ).
[0073] In this embodiment, the side edges 191 of the side wing portion 19 are sequentially joined together and sewn together, the rear arc-shaped edge 193 of the side wing portion 19 is joined together with the rear connecting edge 184 and sewn together, and the front arc-shaped edge 192 of the side wing portion 19 is joined together with the front outward arc-shaped edge 181 and sewn together, so as to close the bottom of the shoe upper piece 11.
[0074] Step 330 (see) Figure 3 ):like Figure 19 As shown, a shoe last 400 is inserted into the wearing space 24 of the shoe-shaped inner sleeve 21.
[0075] Step 340 (see) Figure 3 ):like Figure 19 , 20 As shown in Figure 21, the upper unit 10, the shoe-shaped inner sleeve unit 20 and the shoe last 400 are heated so that the bonding layer 216 is fixed between the upper piece 11 and the shoe-shaped inner sleeve 21, and between the tongue piece 13 and the shoe-shaped inner sleeve 21.
[0076] In this embodiment, the bonding layer 216 is fixed between the inner surface of the upper unit 10 and the outer surface of the shoe-shaped inner sleeve unit 20, so that the upper unit 10 and the shoe-shaped inner sleeve unit 20 are tightly fitted together.
[0077] Step 350 (see) Figure 3 ):like Figure 19 , 20 As shown in Figure 21, an adhesive 41 is used to bond the sole 30 to the bottom of the upper piece 11. In this embodiment, the adhesive 41 is made of hot melt adhesive.
[0078] Step 360 (see) Figure 3 ):like Figure 19 , 20 As shown in Figure 21, the upper unit 10, the shoe-shaped inner sleeve unit 20, the sole 30 and the last 400 are heated to fix the sole 30 to the bottom of the upper piece 11. In this embodiment, the adhesive 41 will be cured into an adhesive layer 40 between the sole 30 and the upper unit 10.
[0079] Step 370 (see) Figure 3 ):like Figure 19 , 22 As shown, the shoe last 400 is removed from the wearing space 24 of the shoe-shaped inner sleeve 21.
[0080] Step 380 (see) Figure 3 ):like Figure 19 , 22 As shown, the shoelace 15 is detachably threaded through the shoelace hole 141 of the eyelet 14.
[0081] Thus, as Figure 22 , 23 As shown, the manufacturing of the breathable and waterproof shoe 100 can be completed.
[0082] Based on the above description, the advantages of the present invention can be summarized as follows:
[0083] I. This invention utilizes a non-elastic upper piece 11 paired with an elastic tongue block 13. The tongue block 13 allows the upper unit 10 to maintain elasticity in the front-back direction of the entry 241 of the wearing space 24 of the shoe-shaped inner sleeve 21, while the upper piece 11 allows the upper unit 10 to exert restraint in the left-right direction of the entry 241 of the wearing space 24 of the shoe-shaped inner sleeve 21. Thus, when the user wears the breathable and waterproof shoe 100, they can use both hands to pull open the loop portion 131 of the tongue block 13, widening the opening width of the entry 51 of the internal space 50 of the upper unit 10 in the front-back direction, thereby increasing the entry angle and facilitating the user to insert their foot into the entry 51 of the internal space 50 of the upper unit 10. 1. During the process of the user inserting their foot into the wearing space 24 of the shoe-shaped inner sleeve 21 through the inlet 51 of the inner space 50 of the upper unit 10, the elasticity of the tongue portion 132 of the tongue block 13 makes it easier for the user to completely insert their foot into the wearing space 24 of the shoe-shaped inner sleeve 21. Afterwards, the non-elastic upper piece 11 can restrain the user's foot in the left and right directions of the inlet 241 of the wearing space 24 of the shoe-shaped inner sleeve 21, so as to prevent the user's foot from accidentally coming out of the inlet 241 of the wearing space 24 of the shoe-shaped inner sleeve 21 during wearing activities. Compared with the prior art, the breathable and waterproof shoe 100 manufactured by the present invention is not only easy to put on, but also does not easily cause the problem of accidental slippage.
[0084] Second, the top connecting end 211 of the shoe-shaped inner sleeve 21 of the breathable and waterproof shoe 100 manufactured by the present invention is folded back to the outside of the wearing space 24 and sewn to the loop portion 131 of the shoe tongue block 13 using the stitch 25. From the inside, the stitch 25 is hidden between the shoe-shaped inner sleeve 21 and the shoe tongue block 13. In this way, not only can the stitching marks inside the breathable and waterproof shoe 100 be simplified and the texture be increased, but the stitch 25 can also be effectively prevented from being worn during wear.
[0085] Third, the present invention utilizes the stitching thread 25 to sew the top connecting end 211 of the shoe-shaped inner sleeve 21 to the loop portion 131 of the shoe tongue block 13. Most of the stitching thread 25 extends along the upper edge of the piping strip 12 on the loop portion 131, which will produce a visually concealed effect. Only a small part of the stitching mark of the stitching thread 25 can be seen on the front side of the loop portion 131 facing the instep notch 186, which can effectively improve the appearance and texture.
[0086] In summary, the present invention provides a breathable and waterproof shoe manufacturing method that prevents slipping and is easy to wear. This method not only makes the manufactured breathable and waterproof shoe easy to put on and prevents accidental slipping, but also simplifies the stitching marks inside the breathable and waterproof shoe and avoids wear on the stitching at the top connecting end of the shoe-shaped inner sleeve during wear. Therefore, the invention truly achieves its objectives.
[0087] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
