Description

Technical Field

[0001] The present disclosure relates to a footwear system and method thereof, and more particularly to a footwear fastening and loosening system and method thereof. Background Art

[0002] Existing shoes often use shoelaces to tighten the shoe body. Figure 1A As shown, after the shoelace 81 of the existing low-top shoes 8 (such as jogging shoes) is wrapped around the shoe body, the user can use the knot 82 to tidy up the excess part of the shoelace 81. In order to avoid the knot 82 from being loosened improperly or the shoelace 81 being too long, some users often use the double knot 82 to increase the tightness. However, when the user wants to take off the low-top shoes 8, the knot 82 must be untied first to increase the wearing and taking off space, and after putting on the low-top shoes 8, the knot 82 must be tied again, which is inconvenient in use. In addition, the tightness of the knot 82 often varies from person to person, making it more difficult to disassemble the knot 82. In addition, if the shoelace 81 is wet, the knot 82 is often more difficult to disassemble.

[0003] In addition, if Figure 1B and Figure 1C As shown, the fastening position 91 of the existing high-top shoes 9 (such as basketball shoes) is relatively high compared to the above-mentioned low-top shoes 8, which means that when the user wants to take off the high-top shoes 9, the shoelaces 92 located at the fastening position 91 must be loosened first (the shoelaces 92 at the fastening position 91 are in a multi-layer overlapping state to ensure their tightness). If they are not loose enough, when putting on and taking off the high-top shoes 9, heel pain, ill-fitting, and reduced wearing and taking off efficiency often occur. In addition to the aforementioned knot method, the shoelaces 92 at the fastening position 91 can be controlled in tightness through a rope buckle 93. When using the rope buckle 93, it is necessary to ensure that the shoelaces 92 have a certain length, otherwise the rope buckle 93 will be separated from the shoelaces 92 when the shoelaces 92 do not reach the tightness that can be put on and taken off. However, the shoelaces 92 with a certain length cannot be effectively stored and will shake with the movement of the user's feet, increasing the trouble of the user. Summary of the invention

[0080] See also Figure 2 The footwear fastening and loosening system disclosed herein includes a shoe body 300 , at least one rope body 400 and a buckle 100 .

[0081] The shoe body 300 includes a toe cap 31, a shoe collar 32, a shoe tongue 33, a plurality of right strap holes 341, 342, 343, and a plurality of left strap holes 351, 352, 353. In the present embodiment, the shoe body 300 is a low-top shoe, such as a jogging shoe, and the number of the right strap holes 341, 342, 343 and the number of the left strap holes 351, 352, 353 are 6, but the present disclosure is not limited thereto. The right belt holes 341, 342, 343 and the left belt holes 351, 352, 353 correspond to each other and correspond to the opposite sides of the tongue 33 respectively, wherein the right belt hole 341 and the left belt hole 351 are closest to the toe 31, and the right belt hole 343 and the left belt hole 353 are closest to the collar 32, multiple right belt holes 342 are located between the right belt hole 341 and the right belt hole 343, and multiple left belt holes 352 are located between the left belt hole 351 and the left belt hole 353, and the area between the multiple right belt holes 342 and the multiple left belt holes 352 can be defined as the middle area MA.

[0082] The rope body 400 is provided with a plurality of right belt holes 341, 342, 343 and a plurality of left belt holes 351, 352, 353, and includes a first line segment 41, a second line segment 42, a first end segment 43 and a second end segment 44. Specifically, the two ends of the rope body 400 may first be provided with a right belt hole 341 and a left belt hole 351 respectively, and then be provided with a plurality of right belt holes 342 and a plurality of left belt holes 352 in a cross manner respectively, and finally pass out from the right belt hole 343 and the left belt hole 353, wherein the rope body 400 passing through the right belt hole 343 may be defined as the first end segment 43, and the rope body 400 passing through the left belt hole 353 may be defined as the second end segment 44, and the first end segment 43 and the second end segment 44 may be tied together to form at least one knot, and the knot may maintain a tightness that allows the user's foot to easily loosen the shoe body 300. In other embodiments, such as Figure 4 As shown ( Figure 4 The technical content of the embodiment and Figure 2 The same parts are not described in detail herein), and when the shoe body 300 is a high-top shoe (such as a basketball shoe), a rope buckle 5 can be provided on the first end section 43 and the second end section 44 so as to be fastened or loosened at the shoe tongue 33 .

[0083] In addition, the rope body 400 is combined with the buckle 100, and the rope body 400 will still be penetrated by the same side of the belt hole after being combined with the buckle 100. For example, the rope body 400 that passes through the right belt hole 342 (the third one from the top to the bottom) will continue to be penetrated by the right belt hole 342 (the second one from the top to the bottom) after being combined with the buckle 100, and the rope body 400 that passes through the left belt hole 352 (the third one from the top to the bottom) will continue to be penetrated by the left belt hole 352 (the second one from the top to the bottom) after being combined with the buckle 100. Therefore, the rope body 400 between any two of the multiple right belt holes 342 that are penetrated in the middle section MA can be defined as the first line segment 41, and the rope body 400 between any two of the multiple left belt holes 352 that are penetrated in the middle section MA can be defined as the second line segment 42.

[0084] See also Figure 5 , Figure 6 and Figure 7 The buckle 100 includes a first buckle 1 and a second buckle 2 that can be assembled with each other. The first buckle 1 has a first operating part 11, a limiting arm 12, a buckle groove 13, a first through groove 14 and an alignment groove 15. The first operating part 11 is roughly in the shape of a block with a trapezoidal cross section and has a first abutment surface 111. The limiting arm 12 has two wings 121 and an arm 122, and the wings 121 extend outward from the opposite sides of the first operating part 11 along the second direction Y and are spaced from each other, and the arm 122 is formed at the end of the wing 121 along the first direction X, that is, the wing 121 and the arm 122 are roughly U-shaped. The arm 122 has a first inclined surface 1221, and the first inclined surface 1221 is facing away from the first operating part 11, but is roughly parallel to the first abutment surface 111. The buckle groove 13 is surrounded and defined by the first operating part 11 and the limiting arm 12. The first through groove 14 is formed through the first operating portion 11 along the first direction X, and its cross section can be a teardrop shape or a trapezoidal shape, but the present disclosure is not limited thereto. The alignment groove 15 is formed recessed from the first abutting surface 111 in the first operating portion 11 and is approximately located at the midpoint of the first operating portion 11 in the first direction X.

[0085] Please also see Figure 8The second fastener 2 has a second operating portion 21, a base 22, a snap block 23, a second through groove 24 and an alignment portion 25. The second operating portion 21 is roughly in the shape of a block with a trapezoidal cross section, and has a second abutment surface 211. The base 22 is formed by extending outward from the second operating portion 21 along the second direction Y, and is roughly in the shape of a square plate. The snap block 23 is formed by extending outward from the base 22, and is spaced apart from the second operating portion 21, and has a roughly U-shaped cross section, but is not limited to this. The snap block 23 has a second inclined surface 231, and the second inclined surface 231 is facing away from the second operating portion 21, but is roughly parallel to the second abutment surface 211. The second through groove 24 is formed in the second operating portion 21 along the first direction X, and its cross section can be teardrop-shaped or trapezoidal, but the present disclosure is not limited to this. The alignment portion 25 is formed to extend outward from the end of the base portion 22 along the second direction Y and is approximately located at the midpoint of the base portion 22 in the first direction X.

[0086] In this embodiment, the direction in which the buckle block 23 extends outward from the base 22 is toward the second operating portion 21. Fig. 9 As shown, the direction in which the buckle block 23 extends outward from the base 22 defines an acute angle θ with the base 22 . The acute angle θ is between 40 and 60 degrees, preferably 50 degrees, but not limited thereto.

[0087] When the buckle 100 is arranged on the shoe body 300, Fig. 9 As shown, the first threading slot 14 is formed by the first line segment 41, and the second threading slot 24 is formed by the second line segment 42. The user can adjust the tightness of the first line segment 41 and the second line segment 42 on the shoe body 300 in advance, so that when the first fastener 1 and the second fastener 2 are not assembled with each other, the shoe body 300 can have a space for wearing and removing, and the user's foot can be easily removed, and when the first fastener 1 and the second fastener 2 are assembled with each other, the shoe body 300 can have no space for wearing and removing, and the user's foot cannot be removed. In addition, in this embodiment, the user can also determine the position of the first fastener 1 and the second fastener 2 on the shoe body 300. The first fastener 1 is located between two adjacent right strap holes 342 closer to the shoe collar 32, and the second fastener 2 is located between two adjacent left strap holes 352 closer to the shoe collar 32, but the present disclosure is not limited thereto. The first fastener 1 and the second fastener 2 may also be located between two right strap holes 342 and two left strap holes 352 closer to the shoe toe 31, respectively, as long as the first fastener 1 and the second fastener 2 are assembled with each other, the shoe body 300 does not have a space for wearing and taking off and the user's foot cannot be taken off. In other embodiments, such as Figure 4As shown, when the shoe body 300 is a high-top shoe (such as a basketball shoe), the first fastener 1 is mainly located between the two adjacent right strap holes 342 closer to the shoe collar 32, and the second fastener 2 is mainly located between the two adjacent left strap holes 352 closer to the shoe collar 32. Neither of them is located between the two right strap holes 342 and the two left strap holes 352 closest to the shoe toe 31. Because the first fastener 1 and the second fastener 2 are located between the two right strap holes 342 and the two left strap holes 352 closest to the shoe toe 31, they cannot effectively produce the function of preventing the user's foot from falling off.

[0088] When the first fastener 1 and the second fastener 2 are assembled with each other, the buckle block 23 is matched and accommodated in the buckle groove 13, the arm portion 122 is limited between the second operating portion 21 and the buckle block 23, the first inclined surface 1221 is adjacent to the second abutting surface 211, the second inclined surface 231 is adjacent to the first abutting surface 111, and the alignment portion 25 is matched and accommodated in the alignment groove 15. At this time, the pulling directions generated by the first line segment 41 and the second line segment 42 on the first fastener 1 and the second fastener 2 are opposite, so that the first fastener 1 and the second fastener 2 will not be separated from each other. In other words, the buckle block 23 is hooked on the arm portion 122 by using the opposite pulling forces generated by the first line segment 41 and the second line segment 42 on the first fastener 1 and the second fastener 2, so that the buckle 100 produces a limiting effect as if the shoelaces have been tied, so that the user's foot cannot be separated from the shoe body 300.

[0089] In this embodiment, when the first fastener 1 and the second fastener 2 are assembled with each other, the first inclined surface 1221 , the first abutting surface 111 , the second inclined surface 231 and the second abutting surface 211 may be substantially parallel to each other, but the present invention is not limited thereto.

[0090] In addition, before the first fastener 1 and the second fastener 2 are assembled with each other, the first end section 43 and the second end section 44 (for example Figure 2 The first end section 43 and the second end section 44 are tied together to form a knot, or as shown in Figure 4 The first end section 43 and the second end section 44 that pass through the rope buckle 5 are placed above the shoe tongue 33. Then, the first fastener 1 and the second fastener 2 are assembled with each other, and the first end section 43 and the second end section 44 can be limited by the fastener 100 and clamped between the fastener 100 and the shoe tongue 33.

[0091] If the first fastener 1 and the second fastener 2 are to be loosened, a thrust greater than the opposite pulling force generated by the first line segment 41 and the second line segment 42 is applied to the first operating portion 11 and the second operating portion 21 at the same time, so that the first fastener 1 and the second fastener 2 are dislocated from each other, that is, the first abutting surface 111 and the second inclined surface 231 are dislocated from each other, and the second abutting surface 211 and the first inclined surface 1221 are dislocated from each other, until the buckle block 23 is disengaged from the buckle groove 13 and the alignment portion 25 is disengaged from the alignment groove 15, so that the first fastener 1 and the second fastener 2 are disassembled from each other. Figure 3 As shown, at this time, the buckle 100 will lose the limiting effect of the shoelaces being tied tightly, and a wearing and taking off space will be created, thereby allowing the user's foot to easily detach from (or enter) the shoe body 300.

[0092] In one embodiment, the first fastener 1 is integrally formed, and the second fastener 2 is also integrally formed, but the present disclosure is not limited thereto.

[0093] In addition, the buckle 100 disclosed herein can be any type of two fasteners that can be assembled with each other, such as a buckle-type buckle with a male buckle or a female buckle that can be interlocked, or two fasteners of a magnetic type, etc., and is not limited to the specific structure of the first fastener 1 and the second fastener 2 mentioned above.

[0094] The present disclosure further provides a shoe fastening and loosening method using the shoe fastening and loosening system, wherein the technical contents of the shoe fastening and loosening method are the same as those of the shoe fastening and loosening system and will not be described in detail.

[0095] First, the aforementioned shoe body 300, rope body 400 and buckle 100 are provided. The two ends of the rope body 400 are respectively penetrated through the right belt hole 341 and the left belt hole 351, and then respectively penetrated through the plurality of right belt holes 342 and the plurality of left belt holes 352 in a cross manner. After selecting the position of the buckle 100 on the shoe body 300, the rope body 400 passing through the right belt hole 342 is penetrated through the first fastener 1, and then the rope body 400 is further penetrated through the right belt hole 342, and the rope body 400 passing through the left belt hole 352 is penetrated through the second fastener 2, and the rope body 400 is further penetrated through the left belt hole 352. Finally, the rope body 400 can be respectively penetrated through the right belt hole 343 and the left belt hole 353. The rope 400 passing through the right belt hole 343 can be defined as the first end section 43, the rope 400 passing through the left belt hole 353 can be defined as the second end section 44, the rope 400 passing through any two of the plurality of right belt holes 342 in the middle section area MA can be defined as the first line segment 41, and the rope 400 passing through any two of the plurality of left belt holes 352 in the middle section area MA can be defined as the second line segment 42. The first end section 43 and the second end section 44 can be arranged by using a knot or a rope buckle 5.

[0096] After the user's foot is put into the shoe body 300 and before the first fastener 1 and the second fastener 2 are assembled with each other, the first end section 43 and the second end section 44 can be placed on the shoe tongue 33. Afterwards, after the first fastener 1 and the second fastener 2 are assembled with each other, the first end section 43 and the second end section 44 can be limited by the fastener 100 and clamped between the fastener 100 and the shoe tongue 33, and the user's foot cannot be separated from the shoe body 300. If the user's foot wants to be separated from the shoe body 300, the first fastener 1 and the second fastener 2 can be separated from each other. Figure 2 In the case of the shoe body 300 shown, since the knot is maintained at a tightness that allows the user's foot to easily loosen the shoe body 300, the user's foot can immediately be detached from the shoe body 300 after the first fastener 1 and the second fastener 2 are separated from each other. Figure 4 In the case of the shoe body 300 shown, after the first fastener 1 and the second fastener 2 are separated from each other, the user only needs to operate the cord buckle 5 to adjust the tightness of the first end section 43 and the second end section 44, and the user's foot can be separated from the shoe body 300. That is, there is no multi-layer overlapping state between the first line segment 41, the second line segment 42, the first end section 43 and the second end section 44 as in the conventional shoelace 92, but the fastener 100 replaces the required tightness of the multi-layer overlapping state of the conventional shoelace 92.

[0097] The beneficial effects that can be achieved by the present disclosure are as follows. Figure 1A In the case of the low-top shoes 8 shown in the figure, the existing low-top shoes 8 must be tied or untied every time they are put on and taken off, and the time for putting on and taking off is long, for example, it takes 13 seconds to tie the knot and 9 seconds to untie the knot. Figure 2 In the case of the shoe body 300 shown, it takes only 2 seconds to assemble the first fastener 1 and the second fastener 2, and only 1 second to detach the first fastener 1 and the second fastener 2.

[0098] In addition, Figure 1B In the case of the high-top shoes 9 shown in the figure, the conventional high-top shoes 9 must be put on and taken off each time by operating the cord buckle 93 to tighten or loosen the multi-layer overlapping shoelaces 92 located at the fastening position 91. For example, it takes 16 seconds to put on and take off the shoelaces 92 by tightening them, and 11 seconds to put on and take off the shoelaces 92 by loosening them. Figure 4 In the case of the shoe body 300 shown, it takes only 5 seconds to assemble the first fastener 1, the second fastener 2 and the operating cord buckle 5, and it takes only 2 seconds to detach the first fastener 1, the second fastener 2 and the operating cord buckle 5.

[0099] In summary, the shoe tightness and loosening system and method disclosed in the present invention can quickly adjust the tightness of the rope body, thereby forming or limiting the wearing and taking off space of the shoes. The user does not need to tie the shoelaces repeatedly, and the ends of the shoelaces can be effectively fixed without shaking. It is easy to use and has low overall cost.
