Technical Field

[0001] The present invention relates to a buckle, and in particular to a buckle for passing shoelaces on shoes and capable of quickly adjusting the tightness of the shoelaces. Background Art

[0002] Conventional shoes often use shoelaces to tighten the shoe body, and after the shoelaces are tied around the shoe body, the user can use a knot to tie up the excess shoelaces. However, when the user wants to take off the shoes, the knot must be untied first to increase the wearing and taking off space, and after putting on the shoes, the knot must be tied again, which is inconvenient. Summary of the invention

[0003] The purpose of the present disclosure is to provide a buckle to solve at least one of the above problems.

[0004] The present disclosure provides a buckle, comprising: a first buckle, having a first operating portion, a limiting arm, a buckle slot and a first through-slot, the limiting arm extending outward from the first operating portion, the buckle slot being surrounded and defined by the first operating portion and the limiting arm, the first through-slot being formed through the first operating portion and being provided for the first rope body to pass through; and a second buckle, having a second operating portion, a base, a buckle block and a second through-slot, the base extending outward from the second operating portion, the buckle block extending outward from the base The second through groove is formed through the second operating part and is spaced apart from the second operating part. The second through groove is formed in the second operating part and is used for the second rope body to pass through. When the first fastener and the second fastener are assembled with each other, the buckle block is matched and accommodated in the buckle groove, and the limiting arm part is limited between the second operating part and the buckle block. At this time, the pulling directions of the first rope body and the second rope body generated by the first fastener and the second fastener are opposite, so that the first fastener and the second fastener will not be separated from each other.

[0005] As in the aforementioned buckle, the buckle block extends outward from the base toward the second operating portion and forms an acute angle with the base.

[0006] As in the aforementioned fastener, when the first fastener and the second fastener are assembled with each other, the first through groove and the second through groove are respectively formed through the first operating part and the second operating part along the first direction, the limiting arm and the base are respectively extended outward from the first operating part and the second operating part along the second direction, and the first direction is perpendicular to the second direction.

[0007] As in the aforementioned buckle, the limiting arm has two wings and an arm portion, the wings are respectively extended outward from the opposite sides of the first operating portion and are spaced apart from each other, the arm portion is formed at the end of the wing portion, and when the first fastener and the second fastener are assembled with each other, the arm portion is limited between the second operating portion and the buckle block.

[0008] As in the aforementioned buckle, the arm portion has a first inclined surface, the first operating portion has a first abutting surface, the buckle block has a second inclined surface, and the second operating portion has a second abutting surface. When the first fastener and the second fastener are assembled with each other, the first inclined surface, the first abutting surface, the second inclined surface and the second abutting surface are parallel to each other, and the first inclined surface is adjacent to the second abutting surface, and the second inclined surface is adjacent to the first abutting surface.

[0009] As in the aforementioned fastener, the first fastener also has an alignment groove, which is recessed in the first operating portion, and the second fastener also has an alignment portion, which extends outward from the base. When the first fastener and the second fastener are assembled with each other, the alignment portion is matched and accommodated in the alignment groove.

[0010] As in the aforementioned buckle, the length of the buckle slot in the first direction is between 1 / 2 and 3 / 4 of the length of the first operating portion in the first direction.

[0011] As in the aforementioned buckle, the acute angle is between 40 and 60 degrees.

[0012] As in the aforementioned buckle, the thickness of the limiting arm is greater than the thickness of the base.

[0013] As in the aforementioned buckle, the cross-sections of the first through-groove and the second through-groove are teardrop-shaped or trapezoidal.

[0014] In summary, the buckle disclosed in the present invention can quickly adjust the tightness of the rope body by whether the first buckle and the second buckle are assembled with each other, thereby forming or limiting the wearing and taking off space of the shoe. The user does not need to tie the shoelaces repeatedly, which is convenient to use and has low overall cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] See also Figure 1 The buckle 100 disclosed herein comprises a first buckle 1 and a second buckle 2 which can be assembled with each other. The structures of the components and the connection relationship between them will be described in detail below, wherein some drawings define a first direction X, a second direction Y and a third direction Z which are perpendicular to each other.

[0052] See also Figure 2 and Figure 3 The first fastener 1 has a first operating portion 11, a limiting arm 12, a snap groove 13, a first through groove 14 and an alignment groove 15. The first operating portion 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 are respectively extended outward from the opposite sides of the first operating portion 11 along the second direction Y and are spaced apart 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 portion 11, but is roughly parallel to the first abutment surface 111. The snap groove 13 is surrounded and defined by the first operating portion 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.

[0053] Please also see Figure 4 The 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.

[0054] In this embodiment, the direction in which the buckle block 23 extends outward from the base 22 is toward the second operating portion 21. Figure 7As 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.

[0055] The following describes the application scenarios of the buckle 100 disclosed in the present invention. Figure 5 and Figure 6 The buckle 100 disclosed in the present invention can be applied to the shoe 3, and the first rope body 31 is passed through the first slot 14, and the second rope body 32 is passed through the second slot 24. The user can adjust the tightness of the first rope body 31 and the second rope body 32 on the shoe 3 in advance, so that when the first fastener 1 and the second fastener 2 are not matched with each other, the shoe 3 can have a wearing and taking off space and the foot can be easily detached, and when the first fastener 1 and the second fastener 2 are matched with each other, the shoe 3 may not have a wearing and taking off space and the foot cannot be detached.

[0056] like Figure 5 and Figure 7 As shown, 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 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 rope body 31 and the second rope body 32 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 opposite pulling forces generated by the first rope body 31 and the second rope body 32 on the first fastener 1 and the second fastener 2 are used to make the buckle block 23 hook the arm 122, so that the buckle 100 produces a limiting effect as if the shoelaces have been tied, and the foot cannot be separated from the shoe 3.

[0057] 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.

[0058] 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 rope 31 and the second rope 32 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 mutually dislocated, that is, the first abutting surface 111 and the second inclined surface 231 are mutually dislocated, and the second abutting surface 211 and the first inclined surface 1221 are mutually dislocated, until the buckle block 23 is separated from the buckle groove 13, and the alignment portion 25 is separated from the alignment groove 15, so that the first fastener 1 and the second fastener 2 can be unassembled with each other. At this time, the buckle 100 will lose the limiting effect as if the shoelaces have been tied, and a wearing and taking-off space will be generated, so that the foot can be separated from the shoe 3.

[0059] In the above embodiment, if Figure 2 As shown, the length L1 of the buckle slot 13 in the first direction X is approximately 3 / 4 of the length L2 of the first operating portion 11 in the first direction X, but is not limited thereto. Figure 8 As shown, the length L1 of the buckle slot 13 in the first direction X may be approximately 1 / 2 of the length L2 of the first operating portion 11 in the first direction X. Regardless of the above embodiments, the size of the buckle block 23 can be matched to be accommodated in the buckle slot 13, and the present disclosure is not limited thereto.

[0060] In one embodiment, if Figure 7 As shown, the thickness D1 of the limiting arm 12 in the third direction Z can be greater than the thickness D2 of the base 22 in the third direction Z. When the first fastener 1 and the second fastener 2 are assembled with each other, the limiting arm 12 can be located between the shoe 3 and the base 22, that is, the first fastener 1 serves as the base of the second fastener 2, thereby increasing stability, and the buckle groove 13 will not be exposed, which can also increase the beauty of the shoe 3 using the buckle 100 of the present disclosure.

[0061] 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.

[0062] In summary, the buckle disclosed in the present invention can quickly adjust the tightness of the rope body by whether the first buckle and the second buckle are assembled with each other, thereby forming or limiting the wearing and taking off space of the shoe. The user does not need to tie the shoelaces repeatedly, which is convenient to use and has low overall cost.
