Technical Field
[0001] The present invention relates to a buckle, and in particular to a buckle for threading shoelaces on shoes and capable of quickly adjusting the tightness of the shoelaces. Background Art
[0002] Existing shoes often use shoelaces to tighten the shoe body, and the shoes are provided with buckles to fix the ends of the shoelaces. However, the buckles on existing shoes mostly use toothed structures to clamp the shoelaces. After a long time of use, the toothed structures will damage the shoelaces, causing inconvenience in use. If the buckle is changed to a buckle structure with a spring to fix the shoelaces, there is a problem of high cost. 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 base and two ribs, the ribs extending outward from the base and spaced apart from each other; and a second buckle, having an operating portion, two limiting arms and two turning grooves, the operating portion being pivotally connected to the ribs with an axis as the core, so that the second buckle can be transformed between a locked state and a released state relative to the first buckle, the limiting arms extending outward from the operating portion and spaced apart from each other, the turning grooves being defined by the operating portion and the limiting arms, respectively, and for a rope to pass through; wherein, in the locked state, the ribs respectively cover part of the turning grooves, so that the rope is limited and bent by the limiting arms and the ribs, so that the rope cannot move in the turning grooves, and in the released state, the ribs are away from the turning grooves, so that the rope is not limited by the ribs and can move in the turning grooves.
[0005] As in the aforementioned buckle, the operating part has a main body and two blocks, the blocks are respectively extended outward from the main body and are spaced apart from each other, the limiting arms respectively have an arm body and a limiting body, the arm bodies are respectively extended outward from the blocks and are bent and fixed to the main body, and the limiting bodies are extended outward from the blocks and are clamped between the main body and the arm bodies.
[0006] As in the aforementioned buckle, the steering groove has a first groove body and a second groove body that are interconnected, the first groove body is defined by the main body, the arm body and the limiting body, and the second groove body is defined by the main body, the block body and the limiting body, so that in the locked state, the rib covers the first groove body and partially extends into the second groove body.
[0007] As in the aforementioned clip, the second clip also has two openings and a receiving space, the openings are formed through the operating portion and are spaced apart from each other, and the receiving space is defined by the operating portion and the limiting arm and connects the openings and the first slot.
[0008] As in the aforementioned buckle, the rope body has two rope segments, which are accommodated in the accommodation space and pass through the opening and the first slot respectively, and wherein the directions in which the rope segments pass through the first slot from the accommodation space are opposite to each other.
[0009] As in the aforementioned buckle, when in the locked state, the rope segment is more easily arranged in the second groove body, and the first bending point is generated by the limiting body and the second bending point is generated by the rib limit, and the bending directions of the first bending point and the second bending point are opposite to each other. When in the released state, the rope segment can detach from the second groove body, and the first bending point is generated by the limiting body.
[0010] As in the aforementioned buckle, the ribs each have a contact surface, and the blocks each have a limiting surface, so that in the locked state, the contact surface and the limiting surface correspond to each other and clamp the rope segment respectively.
[0011] As in the aforementioned buckle, the first buckle also has two pivot holes, which are respectively formed through the rib along the axis, and the operating part also has two pivot columns, which are extended outward from the main body along the axis and are respectively accommodated in the pivot holes.
[0012] As in the aforementioned buckle, the operating portion further comprises a separator, which is formed by extending outward from the main body and is located between the blocks, so as to separate the rope segments and allow the rope segments to pass through the openings respectively.
[0013] As in the aforementioned buckle, the limiting arms further have a snap-on component respectively, and the snap-on components are respectively extended outward from the arm body. The first buckle also has two snap-on parts, and the snap-on parts are recessed in the base. When in the locked state, the snap-on components are respectively snap-on to the snap-on parts.
[0014] In summary, the buckle disclosed herein uses a bent rope structure to fix the rope, which does not cause the problem of the toothed structure wearing the shoelaces, and can quickly adjust the tightness of the rope, and the overall cost is low. In addition, the buckle disclosed herein can directly fix the end of the rope, and does not need to be fixed with a knot at the end, so there is no need to tie the shoelaces repeatedly.

[0059] 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.
[0060] See also Figure 2The first fastener 1 has a base 11, two ribs 12, two pivot holes 13 and two buckle parts 14. The base 11 is roughly a square plate body extending along the first direction X and the second direction Y, and the square plate body can roughly have a curvature, but it is not limited to this. The base 11 has a U-shaped protrusion 111 protruding along the third direction Z. The ribs 12 are formed by the top surface of the base 11 extending outward along the third direction Z, and are spaced apart from each other and adjacent to the two ends of the U-shaped protrusion 111, and each has a contact surface 121, and the contact surface 121 faces the U-shaped protrusion 111. The pivot holes 13 are respectively formed through the ribs 12 along the second direction Y, and are away from the contact surfaces 121. The buckle parts 14 are recessed in the U-shaped protrusion 111, corresponding to each other and spaced apart, and away from the contact surfaces 121 and the pivot holes 13.
[0061] Please also see Figure 3 and Figure 4 The second fastener 2 has an operating portion 21, two limiting arms 22, two turning grooves 23, two openings 24 and an accommodating space 25. The operating portion 21 has a body 211, two blocks 212, two pivot posts 213 and a separator 214. The body 211 is generally formed by extending along a first direction X and a second direction Y. The blocks 212 are respectively extended outwardly from the body 211 along a third direction Z and are spaced apart from each other, and each has a limiting surface 2121. The pivot posts 213 are respectively extended outwardly from the body 211 along the second direction Y in opposite directions to each other, and are respectively accommodated in the pivot hole 13 ( Fig. 9 ), that is, the main body 211 is partially sandwiched between the ribs 12. The separator 214 is formed by extending outward from the main body 211 along the third direction Z and is located between the blocks 212.
[0062] The limiting arms 22 are formed by extending outward from the operating portion 21 and are spaced apart from each other, and respectively have an arm body 221, a limiting body 222 and a buckle 223. The arm body 221 is formed by extending outward from the block body 212 along the first direction X, and then roughly bent toward the third direction Z and fixed to the body 211 (that is, fixed to a position adjacent to the pivot column 213). The limiting bodies 222 are formed by extending outward from the block body 212 along the first direction X and are sandwiched between the body 211 and the arm body 221, and are roughly perpendicular to the limiting surface 2121. The buckles 223 are formed by extending outward from the arm body 221 along the second direction Y in opposite directions to each other, and are respectively adjacent to the block body 212.
[0063] The steering groove 23 is surrounded and defined by the operating portion 21 and the limiting arm 22, and has a first groove body 231 and a second groove body 232 that are connected to each other. The first groove body 231 is surrounded and defined by the body 211, the arm body 221 and the limiting body 222, and the second groove body 232 is surrounded and defined by the body 211, the block body 212 and the limiting body 222. The openings 24 are formed through the operating portion 21 along the first direction X and are spaced from each other. The accommodating space 25 is surrounded and defined by the operating portion 21 and the limiting arm 22, and is connected to the opening 24 and the first groove body 231.
[0064] The following describes the application scenarios and operation conditions of the buckle 100 disclosed in the present invention. Figure 5 The buckle 100 disclosed herein can be applied to a shoe 4 through which a rope 3 is threaded, for example, it can be arranged on the tongue of the shoe 4. Figure 6 The buckle 100 of the present disclosure can also be arranged on the heel guard of the shoe 4. Since the operating portion 21 is pivotally connected to the rib 12 with the axis AX as the axis core, the second buckle 2 can be in a released state ( Figure 7 ) and a locked state ( Fig. 9 ). Figure 7 and Figure 8 As shown, when in the released state, the rib 12 is away from the turning groove 23, and the rope body 3 has two rope segments 31. The rope segments 31 can be respectively passed through the first groove 231, bent and accommodated in the accommodation space 25, and separated by the separator 214, and then respectively pass through the opening 24. In other words, the directions in which the rope segments 31 pass through the first groove 231 from the accommodation space 25 are opposite to each other, and the rope segments 31 can move in the first groove 231 without being limited by the rib 12, and break away from the second groove 232. At this time, the rope segments 31 are respectively bent by the limiting body 222 and generate the first bending point 311.
[0065] When changing from the release state to the locking state, that is, the user applies an external force to the second fastener 2, so that the second fastener 2 rotates relative to the first fastener 1 along the first rotation direction R1. Fig. 9 and Fig.10As shown, when in the locked state, the buckle 223 is buckled in the buckle part 14, so that the rib 12 covers the first slot 231 and partially penetrates the second slot 232. At this time, the rope segment 31 is limited by the limiting body 222 to generate the first bending point 311, and is also limited by the rib 12 to generate the second bending point 312, so that the rope segment 31 is simultaneously accommodated in the first slot 231 and the second slot 232, and the abutting surface 121 and the limiting surface 2121 correspond to each other and clamp the rope segment 31. In this embodiment, the bending directions of the first bending point 311 and the second bending point 312 are opposite to each other, but it is not limited to this. Since the rope segment 31 generates two bending points with different bending directions and is limited by the limiting body 222 and the rib 12, the rope body 3 cannot move in the turning groove 23.
[0066] In one embodiment, the rib 12 may not penetrate into the second groove 232, for example, the edge of the rib 12 is aligned with the edge of the stopper 222, as long as the rope segment 31 can generate the second bending point 312, and the present disclosure is not limited thereto. In addition, the rope body 3 can be a general webbing or elastic rope, and the present disclosure is not limited thereto.
[0067] In this embodiment, the user can freely adjust the position of the rope 3 in the released state to determine the tightness of the rope 3. After the user obtains the desired tightness, the user only needs to apply an external force to the second fastener 2 to rotate the second fastener 2 relative to the first fastener 1 along the first rotation direction R1 to change from the released state to the locked state, and the buckle 223 is buckled in the buckle portion 14 to fix the position of the rope 3. If the user wants to adjust the tightness of the rope 3 again, the user only needs to apply an external force to the second fastener 2 to rotate the second fastener 2 relative to the first fastener 1 along the second rotation direction R2 to change from the locked state to the released state. In this embodiment, the second rotation direction R2 is opposite to the first rotation direction R1.
[0068] In summary, the buckle disclosed herein uses a bent rope structure to fix the rope, which does not cause the problem of the toothed structure wearing the shoelaces, and can quickly adjust the tightness of the rope, and the overall cost is low. In addition, the buckle disclosed herein can directly fix the end of the rope, and does not need to be fixed with a knot at the end, so there is no need to tie the shoelaces repeatedly.
