[0019] The present invention will be described in more detail by referring to the following embodiments.

[0020] Refer to Figures 1 to 4. Figure 1 is a perspective view of the buckle when it is joined according to the first embodiment of the present invention. Figure 2 is a perspective view of the buckle when it is separated. Figure 3 is a cross-sectional view of the buckle when it is joined. Figure 4 is an exploded cross-sectional view of the dashed-line framed portion of the buckle when it is separated in Figure 3. The structure of the buckle 1 includes a top cover 10 and a base 20. For the sake of explanation, only a portion of the top cover 10 and base 20 are shown in Figure 4, and the cut sections are indicated by dashed lines. These technical elements will be described in detail below.

[0021] The top cover 10 includes one cover plate 11 and two first circular insertion parts 12. The shape of the cover plate 11 when viewed from above is oval. That is, the top cover 10 can be considered as a combination of one rectangular plate and two semicircular plates on the left and right. The two first circular insertion parts 12 are formed symmetrically on the two semicircular ends 111 of the cover plate 11, and the external appearance of each first circular insertion part 12 is cylindrical. Preferably, the axis of symmetry of the first circular insertion part 12 (the line connecting the centers of each cross-section) can coincide with the center of one semicircular end 111. The center of the first circular insertion part 12 is open to form a first circular groove 121, and the first magnet M1 is fixed in the first circular groove 121. Since the first magnet M1 can be fitted into the first circular groove 121, the external shape of the first magnet M1 is also cylindrical. The exposed surface of the first magnet M1 can be slightly recessed into the first circular insertion portion 12, as shown in Figure 3. In practice, the exposed surface of the first magnet M1 can also be flush with the end of the first circular insertion portion 12.

[0022] The base 20 includes one bottom plate 21 and two second circular insertion portions 22. The shape of the bottom plate 21 in top view is also oval. Preferably, the shape and dimensions of the bottom plate 21 and the cover plate 11 are identical. The two second circular insertion portions 22 are formed symmetrically on two semicircular ends 211 of the bottom plate 21, and the appearance of each second circular insertion portion 22 is cylindrical. In accordance with the present invention, the axis of symmetry of each second circular insertion portion 22 is also on the center of one semicircular end 211 of the bottom plate 21, and the radius of the cross-section of the second circular insertion portion 22 is the same as the radius of the semicircular end 211. When viewed from above the second circular insertion portion 22, the second circular insertion portion 22 completely covers the lower semicircular end 211, and the edges where the second circular insertion portion 22 and the semicircular end 211 meet overlap. The center of the second circular insertion section 22 is open to form a second circular groove 221. By design, the inner diameter of the second circular groove 221 is slightly larger than the outer diameter of the first circular insertion section 12, and the depth of the second circular groove 221 is the same as or slightly smaller than the height of the first circular insertion section 12. A third circular groove 2212 is formed in the center of the bottom 2211 of the second circular groove 221, and the second magnet M2 is fixed within the third circular groove 2212. The outer shapes of the second magnet M2 and the first magnet M1 are the same, they are cylindrical, and their outer diameters are the same. If their heights are also the same, then the second magnet M2 and the first magnet M1 are exactly the same magnet, but the present invention does not limit their heights. The exposed surface of the second magnet M2 can be slightly recessed into the third circular groove 2212 and can be flush with the surface of the bottom 2211. In this embodiment, because the height of the second magnet M2 is high, the third circular groove 2212 that houses it extends downward into the bottom plate 21 (the bottom of the third circular groove 2212 is located inside the bottom plate 21). If the height of the second magnet M2 is not high, the third circular groove 2212 is formed only within the second circular insertion portion 22 and does not need to extend downward into the bottom plate 21.

[0023] In use, each first circular insertion part 12 can be inserted into a corresponding second circular groove 221, thereby connecting the top cover 10 and the base 20. Furthermore, the top cover 10 and the base 20 are removably connected by the magnetic force between the first magnet M1 and the second magnet M2, and do not easily fall off. The top cover 10 and the base 20 can also be separated when necessary and reattached to another location. When connected, the end of the first circular insertion part 12 abuts against the bottom 2211 of the second circular groove 221.

[0024] Referring to Figures 5 and 6, Figure 5 is a cross-sectional view of another buckle 2 in a coupled state according to a second embodiment of the present invention, and Figure 6 is an exploded cross-sectional view of the dashed-line framed portion of buckle 2 in Figure 5 when separated. As for the appearance when coupled, buckle 1 and buckle 2 are identical and are therefore not shown. Similarly, in Figure 6, only a portion of the top cover 10 and base 30 is shown, and the cut sections are indicated by dashed lines. The structure of buckle 2 includes the same top cover 10 and one different base 30 as in the previously described embodiment, and below, only the technical features of the base 30 will be described in detail.

[0025] The base 30 includes one bottom plate 31 and two second circular insertion portions 32. The top view of the bottom plate 31 is oval in shape, and its shape and dimensions can be made to match those of the cover plate 11. The two second circular insertion portions 32 are formed symmetrically on the two semicircular ends 311 of the bottom plate 31, similar to the method in the previous embodiment in which the second circular insertion portion 22 is formed on the bottom plate 21. The appearance of each second circular insertion portion 32 is cylindrical, with an open center forming a second circular groove 321. The inner diameter of the second circular groove 321 is slightly larger than the outer diameter of the first circular insertion portion 12, but unlike the previous embodiment, the depth of the second circular groove 321 is greater than the height of the first circular insertion portion 12, so that fixing the second magnet M2 inside (at the bottom) of the second circular groove 321 does not affect its use. In this embodiment, the external shapes of the second magnet M2 and the first magnet M1 are identical and both are cylindrical, but their external diameters are different, with the external diameter of the second magnet M2 being larger than that of the first magnet M1. Similarly, in this embodiment, the heights of the two magnets are not limited. Furthermore, because the height of the second magnet M2 is greater, the second circular groove 321 that accommodates it can extend downward into the bottom plate 31. If the height of the second magnet M2 is not greater, the second circular groove 321 can be formed only within the second circular insertion portion 32.

[0026] In use, each first circular insertion portion 12 can be inserted into a corresponding second circular groove 321, thereby allowing the top cover 10 to be coupled to the base 30. The top cover 10 and the base 30 are removably coupled through the magnetic force between the first magnet M1 and the second magnet M2. When coupled, the end of the first circular insertion portion 12 abuts against the second magnet M2.

[0027] Refer to Figure 7. Figure 7 shows a perspective view of a first auxiliary rope loop 40 included in a third embodiment of the present invention. The previous two embodiments introduced the main components of buckle 1 or buckle 2 of the present invention. Based on the present invention, the first auxiliary rope loop 40 shown in Figure 7 may be further included on the foundation disclosed in buckle 1 or buckle 2. The first auxiliary rope loop 40 includes two rigid fixing rings 41 and one connecting rope 42. The rigid fixing rings 41 can be made of a non-elastic material, such as plastic, metal, wood, etc. The rigid fixing rings 41 may be rings with a rectangular cross-section, as shown in Figure 7. In practice, the cross-sectional shape of the rigid fixing rings 41 may be other shapes, such as circular, elliptical, etc. It should be noted that there are limitations on the thickness and inner diameter dimensions of the rigid fixing rings 41. Refer to Figure 9. Figure 9 shows the configuration when the first auxiliary rope loop 40 is connected to the top cover 10 and base 20 of the first embodiment (the same applies when applied to the second embodiment). The combined height of the two rigid fixing rings 41 is less than the height of the second circular insertion section 22 (or 32), and the inner diameter of each rigid fixing ring 41 is slightly larger than the outer diameter of the second circular insertion section 22 (or 32). This design makes it easier to fit the rigid fixing rings 41 onto the outside of the second circular insertion section 22 (or 32), and when the two rigid fixing rings 41 are fitted into the same second circular insertion section 22 (or 32), the first circular insertion section 12 of the top cover 10 and the second circular insertion section 22 (or 32) of the base 30 can be completely joined, and the width of the rigid fixing rings 41 is not too wide to prevent joining.

[0028] In Figure 7, an enlarged view of the area of ​​the first auxiliary rope loop 40 indicated by the dashed line is shown within the solid circle. Within the circle, it can be seen that a fixing groove 411 (shown by a dotted line) is provided on the side of the rigid fixing ring 41. Both ends of the connecting rope 42 are adhesively fixed into the fixing groove 411 of one rigid fixing ring 41. As can be seen from the above description, the design of the first auxiliary rope loop 40 allows the two rigid fixing rings 41 to be removably fitted into each of the two second circular insertion parts 22 (or 32), or to be removably fitted into one of the two second circular insertion parts 22 (or 32) simultaneously. The connecting rope 42 forms a closed loop after being joined to the top cover 10 and the base 20 (or base 30), and can be used for binding or fixing articles.

[0029] In the third embodiment, the first auxiliary rope loop 40 is designed to be made of a relatively inelastic material, but an elastic design may also be used, as in the fourth embodiment described below. Referring to Figure 8, which shows a perspective view of the first auxiliary elastic rope loop 50 included in the fourth embodiment of the present invention. The first auxiliary elastic rope loop 50 includes two elastic fixing ring portions 51 and one connecting rope body 52. ​​The elastic fixing ring portions 51 are more elastic than the rigid fixing ring 41 and can be made of an elastic material, such as rubber. Similarly, the cross-sectional shape of the elastic fixing ring portions 51 is not limited, and the height when the two elastic fixing ring portions 51 are superimposed is smaller than the height of the second circular insertion portion 22 (or 32), and the inner diameter of each elastic fixing ring portion 51 is slightly larger than the outer diameter of the second circular insertion portion 22 (or 32). Since the connecting rope body 52 and the elastic fixing ring portion 51 are made of the same material, they are flexible, similar to the connecting rope 42 in the previous embodiment. However, the length to which the connecting rope 42 stretches when pulled with force is far less than the length to which the connecting rope body 52 stretches when pulled. Both ends of the connecting rope body 52 are connected to one elastic fixing ring portion 51 each.

[0030] Similar to the third embodiment, the two elastic fixing ring portions 51 can be removably fitted into each of the two second circular insertion portions 22 (or 32), or can be removably fitted simultaneously into one of the two second circular insertion portions 22 (or 32). The method is described with reference to Figure 9 and the related description and will not be repeated here. Preferably, the two elastic fixing ring portions 51 and the connecting rope body 52 are manufactured from the same material by integral molding.

[0031] In the two embodiments described above, the number of rigid fixing rings 41 and elastic fixing ring portions 51 is two in both cases, but in practice, the number of these may be only one. Referring to Figure 10, Figure 10 shows a perspective view of a second auxiliary rope loop 60 included in a fifth embodiment of the present invention. The second auxiliary rope loop 60 includes one rigid fixing ring 61 and one connecting rope 62. The rigid fixing ring 61 is similar to the rigid fixing ring 41 described above, the difference being that the thickness of the single rigid fixing ring 61 is smaller than the height of the second circular insertion portion 22 (or 32), and the inner diameter is slightly larger than the outer diameter of the second circular insertion portion 22 (or 32). In Figure 10, an enlarged view of the area indicated by the dashed line frame of the second auxiliary rope loop 60 is shown within the elliptical solid line frame. Within the circular frame, it can be seen that a fixing groove 611 (shown by a dotted line) is provided on the side of the rigid fixing ring 61, and both ends of the connecting rope 62 are adhesively fixed within the fixing groove 611. The connecting ropes 62 and 42 have the same physical properties. For use, the rigid fixing ring 61 can be removably fitted into one of the two second circular insertion parts 22 (or 32).

[0032] Referring to Figure 11, which shows a perspective view of a second auxiliary elastic rope loop 70 included in a sixth embodiment of the present invention. The second auxiliary elastic rope loop 70 includes one elastic fixing ring portion 71 and one connecting rope body 72. The elastic fixing ring portion 71 is similar to the elastic fixing ring portion 51 described above, the difference being that the thickness of the single elastic fixing ring portion 71 is smaller than the height of the second circular insertion portion 22 (or 32), and its inner diameter is slightly larger than the outer diameter of the second circular insertion portion 22 (or 32). The connecting rope body 72 and the connecting rope body 52 have the same physical properties, and both ends are adhesively fixed to the elastic fixing ring portion 71. The elastic fixing ring portion 71 can be removably fitted into either of the two second circular insertion portions 22 (or 32), and the elastic fixing ring portion 71 and the connecting rope body 72 can be manufactured integrally from the same material.

[0033] The buckle of the present invention has several applications. The first is to join (adhere) decorative items, thereby securing them to a rope belt. Referring to Figure 12, which shows a buckle 1 as an example, in which the top cover 10 of the buckle 1 of the present invention and a decorative item D are joined and attached to a rope belt B. The rope belt B may be any type of rope belt, regardless of its width, flatness, or cross-sectional shape, and its method of use is not limited; for example, it can be used as a strap for a shoulder bag. The rope belt B is sandwiched when the top cover 10 and base 20 of the buckle 1 are joined, and the rope belt B passes through the space between the two second circular insertion parts 22, allowing the buckle 1 to slide along the rope belt B. In addition to the above examples of use, the buckle of the present invention can be applied to adding decorations to items such as necklaces, hanging ornaments, dangling ornaments, bags, eyeglasses, handbags, shoulder bags, bibs, clothing, trousers, slippers, sandals, shoes, hats, boots, and high heels.

[0034] A second application of the buckle of the present invention is to restrain the movement of at least one rope belt passing through it, thereby meeting people's needs in daily life. Referring to Figure 13 as an example, Figure 13 shows how the buckle of the present invention is applied to fastening shoelaces S. The buckle 1 can fasten shoelaces S that cross diagonally sideways (large angle), as in the left sneaker, and can also fasten shoelaces S that cross diagonally vertically (small angle), as in the upper part of the right sneaker, thereby limiting the sliding of the shoelaces S on the sneaker and increasing the design of the shoelaces S when in use. Furthermore, the buckle 1 may simply be placed on the shoelaces S, as in the lower part of the right sneaker, without serving to fasten the shoelaces S. In this case, the buckle 1 can be combined with decorative elements to add decoration to the sneaker. The shoelaces S may be of any form, regardless of their width, flatness, or cross-sectional shape.

[0035] A third application of the buckle of the present invention is to restrain a rope belt through the use of an elastic ring (such as a rubber band or elastic rope) or to add decoration to the rope belt by adding a decorative element on the buckle. Referring to Figure 14, which shows how the buckle of the present invention is secured to a rope belt B by an elastic ring R. The elastic ring R is fitted at one end into a second circular insertion part, then wrapped around the rope belt B once, and then fitted into another second circular insertion part before the top cover and base of the buckle 1 are joined (the thick dashed lines indicate where the elastic ring R is obstructed by the top cover).

[0036] Although the present invention has been disclosed with embodiments as described above, this is not intended to limit the invention, and those skilled in the art can make some modifications and alterations without departing from the spirit and scope of the invention, and therefore the scope of protection of the present invention shall be as defined in the appended claims.
