Description

Integrally formed three-dimensional shoe blank with tongue piece and manufacturing method thereof

Technical Field

The present invention relates to a stereo shoe blank with tongue piece and its production method. More particularly, the present invention relates to an integrally knitted three-dimensional shoe sole with tongue pieces and a method for manufacturing the same.

Background

In the traditional shoe making process, the shoe body is formed by connecting a plurality of shoe sheets, so that the material and the manufacturing process for manufacturing the shoe body are very complicated. In recent years, knitted shoes have been developed rapidly and have gradually gained a place in the market due to better ventilation and comfort compared to conventional shoes, less material consumption in the manufacturing process, and lower manufacturing cost.

In general, a knitted shoe is formed by knitting a yarn with a knitting machine to form a shoe blank, and then processing the blank to join the sole. Here, the form of the footwear formed by knitting may vary depending on the type of knitting machine and the knitting method. Because the number of needle beds and the conventional knitting method are limited, a two-needle bed flat knitting machine commonly used in the industry usually weaves a two-dimensional shoe blank of a sheet fabric first, and then the two-dimensional shoe blank is made into a three-dimensional shape by utilizing a sewing technology. However, such delicate and cumbersome sewing work makes it difficult to improve the productivity of the knitted shoe. In addition, the two-dimensional sole typically covers only the instep, so that proper protection of the sole of the foot is lacking, and joint sewing of the two-dimensional sole to the sole, which lacks the sole portion, is relatively difficult. Therefore, the difficulty of combination sewing of the two-dimensional shoe blanks of the sheet-shaped fabric is further improved.

In view of the foregoing, there is a need for the development of integrally formed footwear pieces having various three-dimensional structures and methods for manufacturing or weaving integrally formed footwear pieces including various three-dimensional structures.

To solve the above problems, an embodiment of the present invention provides a method for knitting a three-dimensional shoe blank with a flat knitting machine. The method comprises providing at least one yarn knitted to form a heel and side piece; knitting the heel and the center of the end edge of the side piece to form a rear sole part; the back sole is continued to be woven to form a front sole; the front sole part is continued to be woven to form a vamp part; and continuing the knitting of the upper part of the shoe to form a tongue part. In the method, after the heel and the side piece part are formed, a plurality of to-be-knitted shoe side coils are reserved on first to-be-knitted edges on two sides of the end edge of the heel and the side piece part without unhooking, and when the knitted sole part reaches first to-be-knitted edges on two sides of a preset mesh number, the flat knitting machine can transversely move left and right to respectively enable the boundary of the back sole part to be sequentially knitted with the to-be-knitted shoe side coils which are positioned on the needle bed without unhooking, so that the heel, the side piece part and the back sole part form the three-dimensional shoe back part. In addition, when the front sole part is knitted, needles on two sides are gradually reduced for knitting, a plurality of weft loops to be knitted are reserved on the second edges to be knitted on two sides of the front sole part and are not unhooked on a needle bed, and when the knitted vamp part reaches the second edges to be knitted on two sides, the boundaries of the vamp part are sequentially knitted with the weft loops to be knitted which are located on the needle bed and are not unhooked to form the bag-shaped three-dimensional shoe front part.

In one embodiment, the method for knitting the three-dimensional shoe blank by the flat knitting machine further comprises knitting the heel and side pieces while forming a plurality of shoe holes (10c) on both sides, respectively.

Detailed Description

Various embodiments will be described hereinafter, and the spirit and principles of the invention should be readily understood by those skilled in the art with reference to the following description taken in conjunction with the accompanying drawings. However, while certain specific embodiments are specifically illustrated herein, these embodiments are merely exemplary and are not to be considered in all respects as limiting or exhaustive. Accordingly, various changes and modifications to the invention will be apparent to those skilled in the art without departing from the spirit and principles of the invention.

Hereinafter, a method of weaving an integrally formed three-dimensional footwear according to an embodiment of the present invention will be described with reference to fig. 1 to 4.

Referring to fig. 1, when the shoe blank 100 is woven, at least one yarn may be provided to be sequentially woven to form a heel and side piece portion b10, a rear sole portion b20, a front sole portion b30, a vamp portion b40, and a tongue piece portion b 50.

In the knitting process, the shoe blank 100 can be formed by knitting on both sides of the front/rear needle beds by a two-needle bed flat knitting machine, but not limited thereto. In addition, the at least one yarn described herein may be formed by twisting and combining a plurality of yarns with different properties (such as material, type, form, color, etc.), but is not limited thereto. Further, when different blocks or the same block are knitted, the used knitting yarns can be replaced according to the requirement.

As described above, the embodiment of the present invention will be described by way of example with respect to double knitting with a two-bed flat knitting machine on the front and back needle beds. However, the present invention may be woven by different weaving devices or by hand, and the present invention is not limited thereto, in conformity with the gist of the present invention.

Specifically, referring to fig. 2A in conjunction with fig. 1, according to the manufacturing method of the present invention, at least one yarn 26 is provided to be knitted on both sides of the front needle bed FB and the back needle bed BB to form the heel and side piece b 10. That is, in step S10 of manufacturing the heel and side piece portion b10, first, the yarn 26 is double-side knitted from left to right on the flat knitting machine in an alternating manner in the front needle bed FB and the back needle bed BB in the direction indicated by the arrow S11 in fig. 2A. Then, knitting is performed again in the direction indicated by the arrow S12 on the flat knitting machine from right to left. Here, in order to form the heel and side piece portion b10 of a desired size, the steps shown by the arrows S11 and S12 may optionally be repeated a plurality of times. Finally, following the step indicated by the arrow S12, knitting is performed on the flat knitting machine from left to right in the direction indicated by the arrow S13 until a predetermined position is reached.

The above directions are merely illustrated for convenience of explanation, and as long as the knitting is performed in a reciprocating manner, the actual knitting direction may be opposite to the above example, and different knitting rows may be included.

Referring to fig. 1, in the manufacturing process of the heel and side panel portion b10, one or more shoe holes 10c may be woven on both sides of the front edge of the heel and side panel portion b10, one or more shoe holes 10c may be made on both sides of the front edge with a metal ring after the heel and side panel portion b10 is completed, or the shape of the shoe hole 10c may be further reinforced by weaving a rough contour of one or more shoe holes 10c and making the metal ring. However, the present invention is not limited thereto, and various existing or future-developed technologies may be applied to form one or more eyelets 10c on the heel and side panel part b10, and the positions where the eyelets 10c are formed may also vary depending on the design of the shoe.

In the above knitting, referring to fig. 1 and 2A, after the heel and side piece portion b10 is formed, the

first edges

10a and 10b to be knitted on both sides of the end edge 10 of the heel and side piece portion b10 have a plurality of loops L10 to be knitted on the shoe side left on the front needle bed FB without being unhooked. In detail, since the rear sole portion b20 is knitted to continue the center of the end edge 10 of the heel and side piece portion b10 by a predetermined mesh number (i.e., the center portion 15 of fig. 1), a plurality of loops L10 to be knitted to the shoe side are respectively retained on both sides of the end edge 10 of the heel and side piece portion b10 by the predetermined mesh number.

As described above, after the heel and side piece portion b10 is completed and the plurality of loops L10 to be knitted are left, in step S20, the rear sole portion b20 continues knitting the heel and side piece portion b10 with a predetermined number of stitches extending from the center of the end edge 10. Specifically, the rear sole portion b20 is formed by repeating double-sided knitting a plurality of times on the flat knitting machine in a manner similar to the manner in which the heel and side piece portion b10 is formed by knitting in step S10, in a manner that the front needle bed FB and the rear needle bed BB are reciprocated from right to left/from left to right in a staggered manner.

For example, the rear sole portion b20 can be formed by knitting on both sides of the front needle bed FB and the rear needle bed BB sequentially along the directions indicated by the arrows S21, S22, S23, S24, S25, with a predetermined mesh number (e.g., the central portion 15 in fig. 1 or the 8 mesh number in fig. 2A) continuing from the center of the end edge 10 of the heel and side piece portion b 10. Here, like the heel and side panel part b10, the rear sole part b20 may be formed in a size that determines the number of times of repeating double knitting.

In the above step of knitting the rear sole portion b20, when the rear sole portion b20 reaches the

first knitting edges

20a and 20b on both sides of the predetermined mesh number, the rear needle bed BB can laterally traverse to sequentially knit the stitch position L20 on the boundary of the rear sole portion b20 with the shoe-side stitches L10 to be knitted which are positioned on the front needle bed FB without being unhooked. That is, when knitting is performed to the right side boundary of rear sole portion b20, right side ready-to-knit shoe side stitch L10 can be knitted by corresponding stitch position L20 of the right side boundary of rear sole portion b20 to right side ready-to-knit shoe side stitch L10 of heel and side piece portion b 10. On the other hand, when knitting is performed to the left side boundary of rear sole portion b20, stitch position L20 of the left side boundary of rear sole portion b20 corresponds to left side stitch L10 of heel and side piece portion b10, and left side stitch L10 to be knitted can be continued.

Accordingly, referring to fig. 3A in conjunction with fig. 1 and 2A, when the rear sole portion b20 is knitted, the corresponding shoe side loops L10 to be knitted are knitted in order at the loop positions L20 on the left and right boundaries. Therefore, when the rear sole part b20 is finished, the interlaced connection of the rear sole part b20 and the heel and side piece part b10 is also finished at the same time, so that the rear sole part b20 and the heel and side piece part b10 are folded and connected with each other through the two interlaced

lines

15a and 15b to form the three-dimensional shoe rear part 150.

Next, similarly to the above-described step of forming the stereoscopic shoe rear portion 150, the step of knitting the front sole portion B30 and the vamp portion B40 to form the stereoscopic shoe front portion 350 will be described hereinafter with continued reference to fig. 1, 2B, and 3B.

After the three-dimensional back shoe portion 150 formed by the interweaving of back sole portion b20 with heel and side panel portion b10 is completed, front sole portion b30 is formed by knitting back sole portion b20 on the front/back needle beds. Specifically, referring to fig. 1, front sole b30 is knitted continuously along rear sole b20 from boundary 25 between front sole b30 and rear sole b 20. Referring to fig. 2B, front sole portion B30 is knitted by repeating double-face knitting from right to left and from left to right on the flat knitting machine in a staggered manner on front needle bed FB and back needle bed BB in the directions indicated by arrows S31, S32, S33, S34, S35, S36, and S37 in this order. Similar to the heel and side panel portion b10, the front sole portion b30 may be formed with a size that determines the number of double knit repeats.

Referring to fig. 2B in conjunction with fig. 1, in step S30 of knitting front sole B30, starting from the width of boundary line 25, both sides of front sole B30 will be progressively knitted with decreasing stitches in sequence so that the width of front sole B30 is tapered. In addition, in the knitting step S30, when the front sole portion b30 is knitted to the two side boundaries, the

second selvedges

30a and 30b on the two sides of the front sole portion b30 are left with a plurality of weft loops L30 to be knitted on the front/back needle bed without being unhooked, respectively. Thus, a plurality of weft loops L30 will remain on the

second selvedges

30a and 30b, respectively, after the weaving of the front sole portion b30 is completed.

As described above, after the knitting of front sole part b30 is completed, front sole part b40 is knitted continuously at the front/rear needle beds for the width of front sole part b30 continuing at folding line 35 of front sole part b30 and upper face part b 40. Here, the upper portion b40 can be knitted by repeating double-face knitting a plurality of times in a manner that the front needle bed FB and the back needle bed BB are reciprocated from right to left/from left to right on the flat knitting machine in a staggered manner in the directions indicated by arrows S41, S42, S43, S44, S45, S46, S47, and S48 in this order. Similar to the heel and side pieces b10, the upper b40 may be formed to repeat double knitting repeatedly according to the size of the shoe.

In step S40 of knitting the upper portion b40, as opposed to step S30, both sides of the upper portion b40 are gradually knitted in sequence from the width of the folding line 35 so that the width of the upper portion b40 is gradually increased. In addition, in the knitting step S40, when the upper portion b40 is knitted to the two side boundaries, the front/back needle bed can be laterally moved to sequentially knit the stitch positions L40 on the second knitting edges 40a and 40b on the two sides of the upper portion b40 with the stitches L30 to be knitted which are positioned on the front/back needle bed without being disengaged. That is, when knitting is performed to the right side boundary of the upper part b40, the stitch position L40 of the right side boundary of the upper part b40 corresponds to the right side weft to be knitted L30 of the front sole part b30, and the right side weft to be knitted L30 can be knitted continuously. On the other hand, when knitting is performed on the left side boundary of the upper part b40, the stitch position L40 on the left side boundary of the upper part b40 corresponds to the left side weft to be knitted L30 of the front sole part b30, and the left side weft to be knitted L30 can be knitted continuously.

Accordingly, referring to fig. 3B in conjunction with fig. 1 and 2B, when knitting the upper part B40, the stitch positions L40 at the left and right boundaries are sequentially knitted with the corresponding weft stitches L30 to be knitted. Therefore, when the upper part b40 is completed, the interweaving connection between the upper part b40 and the front sole part b30 is also completed at the same time, so that the upper part b40 and the front sole part b30 are three-dimensional shoe front parts 350 folded and connected with each other by two interweaving

lines

35a and 35b to form a bag shape.

Next, referring to fig. 1, after knitting the three-dimensional forefoot portion 350 formed by the upper portion b40 and the front sole portion b30 being interlaced, in step S50, the upper portion b40 is knitted at the front/rear needle bed to form the tongue portion b50 starting from the width of the boundary line 45. Here, the tongue b50 can be knitted by repeating double-sided knitting a plurality of times in a reciprocating manner from right to left/from left to right on the flat knitting machine in a staggered manner on the front needle bed FB and the rear needle bed BB. In addition, similar to the heel and side piece portion b10, the tongue piece portion b50 may be formed to repeat double knitting repeatedly according to the size of the shoe.

The tongue portion b50 may be knitted by widening from the boundary line 45, by reducing knitting, by equal width knitting, or by optionally adjusting the knitting width as required, and the present invention is not limited thereto.

Referring to fig. 4, after the weaving of the tongue portion b50 is completed, the integrally formed three-dimensional footwear blank 100 may be formed. In detail, the three-dimensional shoe blank 100 is formed as an integral knitted fabric, and includes a heel and side piece portion b10 knitted by at least one yarn and having first sides to be knitted 10a and 10b on both sides; a rear sole part b20 knitted to extend from the central part 15 of the heel and side piece part b 10; a forward sole portion b30 (not shown in fig. 4) knitted in continuation from rearward sole portion b 20; a vamp part b40 knitted continuously from the position of the folding line 35 of the front sole part b 30; and a tongue piece part b50 knitted continuously from the upper part b 40. The two sides of the rear sole portion b20 are respectively provided with a first

continuous selvage

20a and 20b, the three-dimensional sole 100 is interwoven with the first to-

be-woven selvages

10a and 10b through the first

continuous selvages

20a and 20b to form a three-dimensional rear shoe portion 150, and two interwoven

lines

15a and 15b are arranged between the rear sole portion b20 and the heel side piece portion b 10. In addition, the front sole portion b30 (not shown in fig. 4) has

second selvedges

30a and 30b on both sides, the vamp portion b40 has

second selvedges

40a and 40b on both sides, and the three-dimensional sole 100 is interlaced with the

second selvedges

30a and 30b through the

second selvedges

40a and 40b, respectively, such that the front sole portion b30 is connected to the vamp portion b40 and faces to form the bag-shaped three-dimensional forefoot portion 350.

As mentioned above, the shoe holes 10c may be selectively formed in the three-dimensional shoe sole 100, but the invention is not limited thereto, and the three-dimensional shoe sole 100 may not include the shoe holes 10c, or may include other mesh structures similar to the shoe holes.

Hereinafter, a three-dimensional footwear according to various embodiments of the present invention and a method of manufacturing the same will be further described.

Referring to fig. 5, according to a first modified embodiment of the present invention, a three-dimensional shoe blank 200 is an integrally formed knitted fabric knitted by a flat knitting machine. Specifically, the three-dimensional shoe blank 200 and the manufacturing method thereof are substantially the same as those of the reference three-dimensional shoe blank 100 and the manufacturing method thereof, and the difference is that at least one continuous thread material is inserted between the front and rear needle beds to form the throat filling portion b100 having a predetermined thickness while knitting the front edge of the heel and side piece portion b 10. The knitting method of the welt filling part b100 is disclosed in the pressed yarn filling bag-shaped knitting method of taiwan patent TW M529710, and will not be described herein again.

Here, the at least one continuous thread may be a yarn having the same properties as those described above for knitting the heel and side piece portion b10, the rear sole portion b20, the front sole portion b30, the upper portion b40, and the tongue piece portion b 50. However, the present invention is not limited thereto, and the at least one continuous wire may be a material different from the yarn. In addition, the above-mentioned embodiment of the heel and side piece portion b10 having the toe-hole filling portion b100 embedded with the wire and having the predetermined thickness at the front edge thereof can be applied to any of the three-dimensional shoe-blank embodiments described above and below, and is not limited to the embodiment specifically illustrated herein.

Next, referring to fig. 6 to 8, a three-dimensional footwear 300 and a method for manufacturing the same according to a second variation of the present invention will be described.

Referring first to fig. 6, a three-dimensional shoe sole 300 is an integrally formed knitted fabric knitted by a flat knitting machine. Specifically, the three-dimensional blank 300 and the manufacturing method thereof are substantially the same as the reference three-dimensional blank 100 and the manufacturing method thereof, and the difference is that the first collar portion b11 and the second collar portion b12 are further formed before the heel and side piece portion b10 is formed. That is, according to the second variation, both sides of the heel and side piece portion b10 of the three-dimensional shoe blank 300 further include a first collar portion b11 and a second collar portion b12 provided at a position opposite to the first collar portion b 11.

Specifically, referring to fig. 6 and 7, prior to step S10 of forming the heel and side piece portion b10, a knitting step S05 of forming the first collar portion b11 and the second collar portion b12 is further included. As shown in fig. 6 and 7, first collar portion b11 and second collar portion b12 are preferably strips woven from at least one yarn 27 and 28, and are joined by at least one yarn 26 to continue knitting heel and side piece portion b10 after knitting is complete. Here, the first collar portion b11 and the second collar portion b12 are preferably knitted so that double-sided knitting is repeated a plurality of times in a reciprocating manner from right to left/from left to right on the flat knitting machine in a staggered manner on the front needle bed FB and the rear needle bed BB. In addition, similar to the heel and side piece portion b10, the first collar portion b11 and the second collar portion b12 may be formed to repeat double knitting repeatedly according to the size of the shoe. Thus, at least one yarn 27 may be provided to knit on the front/back needle beds to form a first collar portion b11 interwoven with the heel and side panel portion b 10; and at the same time providing at least another yarn 28 to knit on the front/back needle beds to form a second collar portion b12 which is interwoven with the heel and side piece portion b 10.

The first collar portion b11 and the second collar portion b12 may have the same or different lengths partially protruding from the heel and side piece portion b10, and may be interwoven with the same or different yarns as desired. In one embodiment, the yarns 27 and 28 of the first collar portion b11 and the second collar portion b120 are preferably the same yarns as the yarns 26, or may be other yarns different from the yarns 26. In another embodiment, the first collar portion b11 and the second collar portion b12 may be formed by knitting the yarn 26 with other yarns added thereto and then knitting the two sides.

The three-dimensional footwear 300 shown in fig. 8 can be formed by forming the first collar portion b11 and the second collar portion b12 and then continuing the method described above with reference to fig. 1 to 4. As can be seen in fig. 8, the first collar portion b11 and the second collar portion b12 may extend from the three-dimensional shoe rear portion 150 to form an overlapping tongue portion b 50. However, this is merely an example, and the present invention is not limited thereto.

Further, similar to the above-described formation of the shoe hole 10c in the heel and side piece portion b10, one or more shoe holes 10c may be formed at the same time when the first collar portion b11 and the second collar portion b12 are knitted, respectively, under the condition including the first collar portion b11 and the second collar portion b 12. For example, one or more eyelets 10c may be woven on both sides of first collar portion b11 and second collar portion b12, one or more eyelets 10c may be formed on both sides with a metal ring after first collar portion b11 and second collar portion b12 are completed, or the outline of one or more eyelets 10c may be woven and then the metal ring may be used to further enhance the contouring of eyelets 10 c. However, the present invention is not limited thereto, and various existing or future-developed technologies may be applied to form one or more eyelets 10c on the first collar portion b11 and the second collar portion b12, and the positions where the eyelets 10c are formed may also vary depending on the design of the footwear. Accordingly, the first collar portion b11 and the second collar portion b12 of the three-dimensional blank 300 may have a plurality of shoe holes 10c, respectively.

Herein, except for the above differences, the processes of the three-dimensional shoe blank 300 and the manufacturing method thereof, which are the same as those of the reference three-dimensional shoe blank 100 and the manufacturing method thereof, will not be described again.

Next, referring to fig. 9 to 11, a three-dimensional footwear blank 400 including both the throat filling portion b100 and the first and second collar portions b11 and b12 and a method of manufacturing the same according to a third variation of the present invention will be described below.

Referring first to fig. 9, the method of manufacturing the three-dimensional footwear blank 400, similar to the embodiment described above with reference to fig. 6 and 7, includes a step S05 of forming the first collar portion b11 and the second collar portion b 12. Next, after the first collar portion b11 and the second collar portion b12 are formed, the first collar portion b11 and the second collar portion b12 are continued to form a heel and side piece portion b 10.

In step S10 of forming the heel and side piece portion b10, similar to the knitting method disclosed in the aforementioned reference fig. 5 and taiwan patent TWM529710, at least one continuous thread is inserted between the front and rear needle beds to form the throat-filling portion b100 having a predetermined thickness while knitting the front edge of the heel and side piece portion b 10.

In the three-dimensional footwear blank 400 and the method of manufacturing the same shown in fig. 9 to 11, the processes and structures are the same as those of the embodiment shown in fig. 1 to 4, except that the first collar portion b11 and the second collar portion b12 are formed first, and the throat filling portion b100 is formed as in the embodiment of fig. 5 when the heel and side piece portion b10 is knitted. Therefore, details identical or similar to those of the above-described embodiment will not be described herein, and differences from the above-described embodiment will be described hereinafter.

Refer to fig. 10 of the three-dimensional footwear 400 woven from fig. 9. The three-dimensional shoe blank 400 includes a first collar portion b11, a second collar portion b12, and a throat filling portion b100 located at the front edge of the heel and side piece portion b 10. Further, referring to fig. 11, when the three-dimensional footwear blank 400 is cut in an arrow direction by a section line 1000 of fig. 10, the second collar portion b12 partially overlapped with the tongue portion b50 is seen, and the throat filling portion b100 for achieving a desired thickness is seen to contain the filled continuous wire 56.

Hereinafter, a three-dimensional footwear 500 and a method of manufacturing the same according to a fourth variation of the present invention will be described with reference to fig. 12 and 13.

Referring to fig. 12 and 13, the three-dimensional shoe blank 500 has a first collar portion b11 and a second collar portion b12, which are the same as the three-dimensional shoe blank 300 shown in fig. 6, and the three-dimensional shoe blank 500 further differs in that the heel and side piece portion b10 further includes an upper portion b13 protruding from the heel and side piece portion b10 and interlaced with the heel and side piece portion b 10.

Upper portion b13 may be formed in a manner similar to that described above with reference to fig. 6 for first collar portion b11 and second collar portion b 12. Specifically, the step S05 of knitting the first collar portion b11 and the second collar portion b12 further includes, before knitting the heel and side piece b 10: at least one yarn is provided to knit at the front/back needle beds to form an upper portion b13 protruding from the heel and side piece portion b10 and to be interwoven with the heel and side piece portion b 10.

That is, the first collar portion b11, the second collar portion b12, and the upper portion b13 may be substantially similar extensions woven with at least one different or the same yarn, and the heel and side piece portion b10 may be knitted in a continuous row after knitting is completed such that the first collar portion b11, the second collar portion b12, and the upper portion b13 partially protrude from the heel and side piece portion b 10. Therefore, the knitting method of the upper part b13 is substantially the same as that of the first collar part b11 and the second collar part b12, and the positions, lengths and sizes of the first collar part b11, the second collar part b12 and the upper part b13, which partially protrude from the heel and side piece part b10, may be designed according to the needs, and the present invention is not limited thereto.

For example, the upper b13 can be designed to be disposed between the first collar b11 and the second collar b12, and partially protrude from the center of the front edge of the heel and side piece b10 to form a semicircular extension. Referring to fig. 13, the three-dimensional footwear 500 knitted by the above method includes a semicircular extension portion protruding upward from the front edge of the heel and side piece portion b10, so that it is possible to assist a user to lift the footwear body by grasping the upper portion b13 when wearing the footwear. However, the shapes and functions of the first collar portion b11, the second collar portion b12, and the upper portion b13 are merely examples, and the present invention is not limited thereto. That is, various shapes of extensions partially protruding from the heel and side piece portion b10 may be formed, and such extensions may have various functions, in keeping with the spirit of the present invention.

Next, a variation of the first collar portion b11 and the second collar portion b12 according to the fifth variation of the present invention will be described with reference to fig. 14 and 15.

Referring to fig. 14, according to a fifth modified embodiment of the present invention, the three-dimensional footwear 600 includes a first collar portion b11 and a second collar portion b12, similar to the embodiment described above with reference to fig. 6. However, unlike the embodiment described above with reference to fig. 6, the first collar portion b11 and the second collar portion b12 of the three-dimensional blank 600 may be knitted through steps S01 and S02, respectively, thereby forming extension portions having different lengths and even shapes. For example, step S02 may be performed first to form the second collar portion b12 having a longer length, and step S01 may be performed in parallel to form the first collar portion b11 having a shorter length in the middle of knitting the second collar portion b 12. That is, step S01 for forming first collar portion b11 and step S02 for forming second collar portion b12 may overlap for at least a period of time.

Here, the manner of knitting the first collar portion b11 and the second collar portion b12 is substantially the same as the embodiment shown in fig. 6 except for the shape and size, and thus detailed description thereof will not be repeated.

According to the three-dimensional footwear piece 600 of this embodiment, compared to the three-dimensional footwear piece 300 of the embodiment shown in fig. 6, the arrangement of the connecting member 91 and the connecting member 92 is further included, except that the relative shapes of the first collar portion b11 and the second collar portion b12 are different.

Specifically, in the three-dimensional blank 600, the connecting member 91 may be disposed on the second collar portion b12 during or after knitting, and the connecting member 92 may be disposed on the first collar portion b11 or the heel and side piece portion b10 to be coupled with the connecting member 91. For example, referring to fig. 15, a connecting member 91 may be provided on the second collar portion b12, and a connecting member 92 may be provided on the heel and side piece portion b10 corresponding to the first collar portion b 11. Therefore, when the second collar portion b12 overlaps the first collar portion b11, the connector 91 is just coupled with the connector 92, thereby facilitating the wearing fixation of the shoe. However, the present invention is not limited to the aspects shown in fig. 14 and 15, and the connecting member 91 and the connecting member 92 can be disposed on the first collar portion b11 and the second collar portion b12 respectively or at other corresponding positions under the corresponding matching connection.

Here, the connecting member 91 and the connecting member 92 may be a corresponding magnet set, a zipper, a strap, a hidden button, a male and female buckle, a clip, a button set, a hook and loop fastener, a velcro tape, etc., and any other objects than the above may be used as long as the connecting member 91 and the connecting member 92 can be attached to each other, and the invention is not limited thereto.

The first and second collar portions b11 and b12 are described for convenience of description, and their designations may be interchanged. That is, although the second collar portion is longer than the first collar portion and the

connectors

91 and 92 are respectively disposed corresponding to the second collar portion and the first collar portion in the above description, the first collar portion may be longer than the second collar portion and the

connectors

91 and 92 may be respectively disposed corresponding to the first collar portion and the second collar portion, as long as the names are interchanged.

The above-mentioned various aspects described with reference to fig. 1 to fig. 15, such as the upper portion, the first collar portion, the second collar portion, the collar filling portion, and other structural aspects, can be mutually combined and changed into different variation embodiments without conflict, and will not be described herein again.

According to one or more embodiments of the present invention, an integrally formed footwear blank having a three-dimensional structure may be formed when knitting is completed. Therefore, the three-dimensional shoe blanks can be formed more efficiently, the sewing and combining operation procedure is omitted, and the cost and the time for manufacturing the shoe blanks are further improved. In addition, the three-dimensional shoe blank formed by the method also has better integrity, thereby improving the integrity of the appearance of the shoe body.

What has been described herein are merely some of the presently preferred embodiments of the invention. It should be noted that various changes and modifications can be made in the present invention without departing from the spirit and principle of the invention. It should be understood by those skilled in the art that the present invention is defined by the appended claims and various changes, substitutions, combinations, modifications and alterations can be made without departing from the scope of the invention as defined by the appended claims.
