Description

Technical Field

[0001] The present invention relates to the field of clothing accessories, and particularly to a fastening device and a self-aligning zipper. Background Art

[0002] Zippers, as important accessories in the clothing field, have been fully applied to various garments. Generally speaking, zippers require two-handed operation, that is, when using a fastening device to lock the slider on both track sides, both hands need to be used simultaneously, which is rather troublesome.

[0003] Based on this, some people have proposed a self-aligning zipper that can be operated with one hand. For example, the self-aligning zipper disclosed in the Chinese invention patent disclosure specification with the publication number CN103917124A and its national counterpart patent specifications includes: a first lower body including a first magnet, a convex retaining element, and a first extension; a first zipper track having a plurality of teeth and fixed to the first lower body; a slider slidably connected to the first zipper track; a second lower body including a second magnet, a concave retaining element, and a second extension; a second zipper track having a plurality of teeth and fixed to the second lower body; the concave retaining element of the second lower body has a notch for receiving the convex retaining element of the first lower body and has an inclined surface for guiding the concave retaining element of the second lower body to be correctly aligned with the convex retaining element of the first lower body by the attraction of the first magnet and the second magnet.

[0004] However, in the actual use process, due to the setting of the inclined surface, although it can guide the concave retaining element to be correctly aligned with the convex retaining element, it also limits the alignment angle between the concave retaining element and the convex retaining element, that is, only when the concave retaining element is released at an angle parallel to the inclined surface can the concave retaining element and the convex retaining element be aligned and magnetically attracted. This severely restricts the usage mode of the self-aligning zipper. In daily use, the concave retaining element and the convex retaining element may not be correctly aligned because the user fails to align the angle as scheduled.

[0005] Based on this, it is necessary to propose a self-aligning zipper to solve the above problems. Summary of the Invention

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0027] It should be noted that the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes and cannot be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] Refer to Figures 1-3An embodiment of a fastening device of the present invention as shown includes: a first base 30 and a second base 40. The first base 30 includes a first fixing portion 3 and a first magnet 2 disposed within the first fixing portion 3. An outer edge of the first fixing portion 3 is provided with a first protrusion 31 extending horizontally, the first protrusion 31 is provided with a receiving portion 32, and a recessed portion is provided beside the first protrusion 31.

[0029] The second base 40 includes a second fixing portion 4 and a second magnet 5 disposed within the second fixing portion 4. An outer edge of the second fixing portion 4 is provided with a second protrusion 41 extending horizontally, and the second protrusion 41 is configured to guide the second fixing portion 4 to be correctly aligned with the first fixing portion 3 and enter the recessed portion through the attraction between the first magnet 2 and the second magnet 5.

[0030] The second fixing portion 4 is further provided with a wedge portion 42. When the second fixing portion 4 is correctly aligned with the first fixing portion 3, the wedge portion 42 is located within the receiving portion 32. Specifically, the wedge portion 42 is a protrusion perpendicular to the axis of the second base 40, and the shape can be set as a plug type, a cone, a hemisphere, or a frustum. Such structural variations still fall within the protection scope of the present invention. In this embodiment, the receiving portion 32 is a through hole opened on the first protrusion 31, or can also be a counterbore provided towards the inner side of the first protrusion 31. Such structural variations still fall within the protection scope of the present invention.

[0031] By respectively providing protrusions on the first base 30 and the second base 40 and using the attraction of the magnets to guide and combine the two bases, and finally forming a lock through the combination of the wedge portion 42 and the receiving portion 32, it avoids the problem in the prior art that the bases can only be combined at a specific angle due to the inclined surface 33 of the protrusion provided on the second base 40, enabling the user to quickly pull up the zipper with one hand whether horizontally or with a slight inclination, improving the usage efficiency.

[0032] The second protrusion 41 is at least two, and the recessed portion is provided with an inclined surface 33. The inclined surface 33 is configured to push the side of the second protrusion 41 when the second fixing portion 4 is guided to be correctly aligned with the first fixing portion 3 through the attraction between the first magnet 2 and the second magnet 5, so that the wedge portion 42 is located within the receiving portion 32. The setting of the inclined surface 33 further avoids the situation where the first base 30 and the second base 40 cannot be aligned due to the interference of the wedge portion 42 during the attraction process between the first magnet 2 and the second magnet 5.

[0033] Specifically, a protruding ridge portion 34 is provided in the middle of the recessed portion, and the inclined surfaces 33 are respectively provided on both sides of the ridge portion 34. Through the setting of the ridge portion 34, the inclined surface 33 is provided to ensure the accuracy of the alignment process.

[0034] The inner edge of the first protrusion 31 is arranged as an arc surface or an inclined surface 33 for guiding the wedge part 42 into the accommodating part 32. The arrangement of the arc surface or the inclined surface 33 enables the wedge part 42 to smoothly enter the accommodating part 32 under the guidance of the arc surface or the inclined surface 33 when entering the accommodating part 32, thus avoiding the phenomenon of inclined sliding misalignment that may cause the wedge part 42 to fail to correctly enter the accommodating part 32.

[0035] To further ensure the alignment efficiency, the outer shapes of the first base 30 and the second base 40 are both regular polygons to prevent rotation that may lead to misalignment. Preferably, the outer shapes of the first base 30 and the second base 40 are both regular hexagons. The setting of the regular hexagon also provides better usability and prevents the sliding phenomenon of the human hand during the operation of the base due to the circular outer shape.

[0036] In this embodiment, one of the first magnet 2 and the second magnet 5 is made of a magnetic material such as ferromagnetic material, and the other is made of iron material. In other embodiments, the opposite sides of the first magnet 2 and the second magnet 5 are opposite magnetic poles.

[0037] The present invention also provides a self-aligning zipper. Refer to Figure 1 the illustrated embodiment, which includes:

[0038] The fastening device as described above;

[0039] A first zipper track 7, including a plurality of teeth and connected to the first base 30;

[0040] A second zipper track 8, including a plurality of teeth and connected to the second base 40;

[0041] A zipper head (not shown in the figure), slidably connected to the first zipper track 7 and the second zipper track 8 respectively for meshing the teeth of the first zipper track 7 and the second zipper track 8.

[0042] By providing the fastening device as described above on the zipper, providing protrusions on the first base 30 and the second base 40 respectively, and using the attraction of the magnets to guide and combine the two bases, finally forming a lock through the combination of the wedge part 42 and the accommodating part 32, and completing the connection and meshing of the first zipper track 7 and the second zipper track 8 through the zipper head, when using the zipper of the present invention, it can be completely operated with one hand, improving the use efficiency.

[0043] A first fixing seat 1 is further provided between the first zipper track 7 and the first base 30, and a first extension part 11 is provided on the first fixing seat 1.

[0044] A second fixing seat 6 is further provided between the second base 40 and the second zipper track 8. A second extension portion 61 is provided on the second fixing seat 6. The first extension portion 11 and the second extension portion 61 cooperate to stop the slider from sliding down and provide zipper actuation. The first fixing seat 1 and the second fixing seat 6 are used to fix the first base 30 and the second base 40 respectively.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
