Description

Technical field

[0001] The present utility model relates to the technical field of zippers, in particular to a zipper device used on articles such as clothing, bags and tents.

[0002] The present utility model also relates to an article equipped with the zipper device. STATE OF THE ART

[0003] A zipper is a fastener used to join or separate objects by means of continuously arranged elements. Generally, a zipper comprises a pair of left and right fabric tapes, rows of elements attached to the inner edges of the fabric tapes, and a slider that engages the rows of elements. Each row of elements contains a multitude of elements arranged side by side along the front-to-back length of the zipper. When the slider is pulled forward or backward along the length of the zipper, the two rows of elements are joined or separated, thus opening or closing the zipper.

[0004] Some zippers in the prior art incorporate a separating insert. The separating insert mainly comprises an insert body (also referred to as a "separating pin") and a rotating support body (also referred to as a "retaining pin"). The insert body is continuously formed at one end of the element row on one of the two fabric strips, and the rotating support body is continuously formed at one end of the element row on the other of the two fabric strips. When the zipper is closed, the insert body is inserted and engaged from the side of the rotating support body along the width of the zipper, and when the zipper is opened, the insert body is withdrawn from the side of the rotating support body along the width of the zipper.To facilitate the engagement of the insert body and the rotating support body, magnets are often incorporated into both the insert body and the rotating support body, as is the case, for example, in the zipper disclosed in Chinese patent application No. 201880098364.4.

[0005] When a zipper equipped with a separator insert is used to open or close garments such as coats or trouser legs, the separator insert is generally located at the bottom of the garment. The wearer must pull the zipper slider along the extension of the zipper towards the bottom of the garment and then insert the separator insert body into the side of the pivot body or pull the separator insert body out of the side of the pivot body, along the width of the zipper. However, because the insert body and pivot body are generally small, it can be difficult to insert and engage them at the bottom of the garment, especially if the garment is large and thick (e.g.,Winter clothing) or if the wearer is wearing gloves or has poor eyesight. In these cases, the sequence of actions, in which the insert is inserted into the rotating support body and then the slider is grasped and pulled at this position, becomes more difficult and uncomfortable at this remote position at the bottom of the clothing. SUMMARY OF THE USAGE SAMPLE

[0006] In view of the aforementioned disadvantages of the prior art, the technical problem to be solved by the present utility model is to provide a pull tab with a removable pull tab auxiliary part which not only ensures reliable fastening between the pull tab auxiliary part and the main body of the pull tab after installation of the pull tab auxiliary part, but also improves the aesthetic appearance of the main body of the pull tab.

[0007] In view of the aforementioned disadvantages of the prior art, the technical problem to be solved by the present utility model is to provide a zipper device that facilitates the engagement of a separating insert in the zipper device.

[0008] To achieve the aforementioned objective, the present utility model provides for a zipper device comprising the following: a first zipper element and a second zipper element arranged side by side along a longitudinal direction of the zipper device, wherein the first zipper element comprises a pair of first fabric strips, a first element row attached to an inner edge of each of the first fabric strips, a first slider movably attached to the first element row, a first separator insert provided at a distal end of the first zipper element, a first magnetic body and a second magnetic body, the first separating insert comprises a first retaining pin and a first separating pin, each attached to the inner edges of the pair of first fabric strips, provided at a distal end of the first row of elements and arranged to be separated from each other and engaged with each other, a distal end of the first retaining pin is provided with a first retaining pin base and a distal end of the first separating pin is provided with a first separating pin base, the first retaining pin base and the first separating pin base are arranged so that they can be separated from each other and engaged with each other, where the first magnetic body is attached to the first retaining pin base, and the second magnetic body is attached to the first separating pin base, the magnetic poles of the first magnetic body and the second magnetic body, which are opposite each other in a separating or engagement direction of the first retaining pin base and the first separating pin base, have opposite polarities. the second zipper element comprises a pair of second fabric strips, a second element row attached to an inner edge of each of the second fabric strips, a second slider movably attached to the second element row, a second separating insert provided at a distal end of the second zipper element, a third magnetic body and a fourth magnetic body, the second separating insert comprises a second retaining pin and a second separating pin, each attached to the inner edges of the pair of second fabric strips, provided at a distal end of the second row of elements and arranged so that they can be separated from each other and engaged with each other, a distal end of the second retaining pin is provided with a second retaining pin base and a distal end of the second separating pin is provided with a second separating pin base, the second retaining pin base and the second separating pin base are arranged so that they can be separated from and engaged with each other, the third magnetic body is attached to the second retaining pin base and the fourth magnetic body is attached to the second separating pin base, magnetic poles of the third magnetic body and the fourth magnetic body, which are opposite each other in a separation or engagement direction of the second retaining pin base and the second separating pin base, have opposite polarities, and the distal end of the first zipper element and the distal end of the second zipper element abut each other, so that the first separating insert and the second separating insert are both provided at non-end positions on the zipper device along its longitudinal direction.

[0009] In the zipper device according to the present application, the first zipper element and the second zipper element are arranged such that they abut each other at their distal ends, thereby ensuring that the first separating insert at the distal end of the first zipper element and the second separating insert at the distal end of the second zipper element are both located in non-end positions on the zipper device along the longitudinal direction. This prevents the first separating insert and the second separating insert of the zipper device from interfering with each other at their ends (e.g.,the lower part) of an article such as a coat or trousers along its longitudinal direction when the zipper device is attached to the article, and the first separating insert and the second separating insert are provided along the longitudinal direction of the article from its ends, thereby achieving a centered or nearly centered arrangement of the first separating insert and the second separating insert on the zipper device along the longitudinal direction, which facilitates the engagement process between the first retaining pin and the first separating pin, as well as the engagement process between the second retaining pin and the second separating pin.During the engagement process, the first holding pin and the first separating pin are magnetically coupled via the first magnetic body and the second magnetic body, thereby facilitating the engagement process of the first holding pin and the first separating pin, and similarly, during the engagement process, the second holding pin and the second separating pin are magnetically coupled via the third magnetic body and the fourth magnetic body, thereby facilitating the engagement process of the second holding pin and the second separating pin.

[0010] Furthermore, the first zipper element and the second zipper element are two zipper elements of the same length, arranged symmetrically along the longitudinal direction, whereby the first separating insert and the second separating insert are both provided at an intermediate position of the zipper device along its longitudinal direction, which facilitates the engagement process between the first retaining pin and the first separating pin, as well as the engagement process between the second retaining pin and the second separating pin.

[0011] Furthermore, in the first zipper element, the first retaining pin base and the first separating pin base are arranged to overlap in one thickness direction of the first zipper element, and the magnetic poles of the first and second magnetic bodies, which are opposite each other in the thickness direction of the first zipper element, have opposite polarities. Therefore, in the first zipper element, the first retaining pin base and the first separating pin base are magnetically coupled in the thickness direction of the first zipper element via the first and second magnetic bodies, thus providing a positioning for the engagement of the first retaining pin and the first separating pin, which further facilitates their engagement.

[0012] Similarly, in the second zipper element, the second retaining pin base and the second separating pin base are arranged to overlap in one thickness direction of the second zipper element, and the magnetic poles of the third and fourth magnetic bodies, which are opposite each other in the thickness direction of the second zipper element, have opposite polarities. Therefore, in the second zipper element, the second retaining pin base and the second separating pin base are magnetically coupled in the thickness direction of the second zipper element via the third and fourth magnetic bodies, thus providing a positioning for the engagement of the second retaining pin and the second separating pin, which further facilitates their engagement.

[0013] Furthermore, along the longitudinal direction of the zipper device, the first retaining pin base and the second retaining pin base are arranged opposite each other, and the first separating pin base and the second separating pin base are arranged opposite each other, with the magnetic poles of the first and third magnetic bodies facing each other longitudinally having opposite polarities, and the magnetic poles of the second and fourth magnetic bodies facing each other longitudinally having opposite polarities. This arrangement causes the first and second retaining pin bases to tend to approach each other along the longitudinal direction of the zipper device, and the first and second separating pin bases also tend to approach each other along the longitudinal direction of the zipper device.This reduces the gap at the butt joint between the first and second zipper elements of the zipper device, or in other words, prevents the repulsion between the first and third magnetic bodies, as well as the repulsion between the second and fourth magnetic bodies, from creating an additional gap at the butt joint between the first and second zipper elements, thereby improving the aesthetic appearance of the zipper device and enhancing the integrity of the first and second zipper elements when closed.

[0014] Furthermore, the zipper device comprises a lining fabric arranged on the back of a butt joint between the first zipper element and the second zipper element, wherein an outer edge of the lining fabric is attached in the width direction of the zipper device to the first fabric strip and / or the second fabric strip, and the lining fabric covers a gap at the butt joint between the first zipper element and the second zipper element.Providing a lining can, on the one hand, improve the aesthetic appearance of the zipper device and enhance the integrity of the first and second zipper elements when closed, and on the other hand, it can block the gap at the butt joint between the first and second zipper elements, thus preventing inner parts of an article equipped with the zipper device from being exposed through this gap.

[0015] Furthermore, the zipper device comprises a first handle and a second handle arranged opposite each other along a width direction of the zipper device, wherein the first handle and the second handle are both provided at a butt joint between the first zipper element and the second zipper element, wherein the first handle is attached to a first fabric strip and / or a second fabric strip on one side in the width direction of the zipper device and the second handle is attached to a first fabric strip and / or a second fabric strip on the other side in the width direction of the zipper device.To open the zipper device, first the first slider is pulled to the distal end of the first zipper element and the second slider to the distal end of the second zipper element, and then, by holding the first handle and the second handle and applying an outward force along the width direction of the zipper device, the first retaining pins and the first separating pins can be easily separated from each other, and the second retaining pin and the second separating pin can be easily separated from each other, thus facilitating the opening of the zipper device.

[0016] Furthermore, in a preferred embodiment of the first and second handles, two ends of the first handle are each attached to the first and second fabric strips on one side in the width direction of the zipper assembly, and two ends of the second handle are each attached to the first and second fabric strips on the other side in the width direction of the zipper assembly. Preferably, both the first and second handles can be curved (e.g., arc-shaped or U-shaped) or concave, thereby varying the appearance of the zipper assembly.

[0017] Furthermore, in another preferred embodiment of the first handle and the second handle, both the first handle and the second handle are attached to a front of an article equipped with the zipper device.

[0018] Preferably, both the first and second handles can be designed as pocket-like structures, so that hand openings are formed between the first handle and an item equipped with the zipper device, and between the second handle and the item. This makes it easier for the user to hold the first and second handles through the hand opening, thus making it convenient for the user to exert force to separate the first and second divider inserts.

[0019] The present utility model further provides an article comprising: a first part and a second part arranged so that they can be separated from each other and engaged with each other; and the zipper device described above, wherein the first fabric strip and the second fabric strip are both attached to an inner edge of the first part on one side in the width direction of the zipper device, and the first fabric strip and the second fabric strip are both attached to an inner edge of the second part on another side in the width direction of the zipper device, and the first part and the second part are arranged so that they can be separated from each other and engaged with each other by the zipper device.

[0020] As described above, the zipper device and the article according to the present utility model have the following advantageous effects.

[0021] In the zipper device according to the present application, the first separating insert at the distal end of the first zipper element and the second separating insert at the distal end of the second zipper element are both provided at non-end positions along the longitudinal direction of the zipper device. This allows the first separating insert and the second separating insert, when the zipper device is attached to an article, to be positioned centrally or approximately centrally on the zipper device along its longitudinal direction, which facilitates the engagement process between the first retaining pin and the first separating pin, as well as the engagement process between the second retaining pin and the second separating pin.

Therefore, the first zipper element 20 comprises a pair of first fabric strips 21 arranged side by side on the left and right, the first element row 22 attached to an inner edge of each of the first fabric strips 21 and extending from front to back, the first slider 23, and the first separating insert 24 provided at the distal end of the first zipper element 20. Each row of the first element rows 22 comprises a plurality of elements arranged side by side along the longitudinal direction of the zipper from front to back.The first slider 23 is movably attached to the left first element row 22 and aligned in the front-back direction with the first retaining pin 25. Furthermore, the first zipper element 20 also includes a first magnetic body 27 and a second magnetic body 28, wherein the first magnetic body 27 and the second magnetic body 28 are each attached to the first retaining pin 25 and the first separating pin 26, respectively, thereby magnetically coupling the first retaining pin 25 and the first separating pin 26 during engagement.

[0030] As in the Fig. As shown in Figures 1 to 3, the second zipper element 30 is an independent zipper element equipped with a separating insert. One end of the second zipper element 30, along its longitudinal direction where the separating insert is attached, is defined as the distal end of the second zipper element 30, and one end of the second zipper element 30, along its longitudinal direction away from the separating insert, is defined as the tip end of the second zipper element 30. The second zipper element 30 comprises a left half and a right half, which can be separated and interlocked in a left-right direction.The left half of the second zipper element 30 comprises a second fabric strip 31, a second row of elements 32 attached to a right edge of the second fabric strip 31, a second slider 33 movably mounted on the left second row of elements 32 along the longitudinal direction of the second zipper element 30, and a second retaining pin 35 attached to the right edge of the second fabric strip 31 and located at the distal end of the left second row of elements 32. The right half of the second zipper element 30 comprises the second fabric strip 31, the second row of elements 32 attached to a left edge of the second fabric strip 31, and a second separating pin 36 attached to the left edge of the second fabric strip 31 and located at the distal end of the right second row of elements 32.The second retaining pin 35 and the second separating pin 36 form a second separating insert 34 of the second zipper element 30, and the second retaining pin 35 and the second separating pin 36 can be separated and engaged with each other in the width and thickness directions of the second zipper element 30. Therefore, the second zipper element 30 comprises a pair of second fabric strips 31 arranged side by side on the left and right, the second element row 32 attached to an inner edge of each of the second fabric strips 31 and extending from front to back, the second slider 33, and the second separating insert 34 provided at the distal end of the second zipper element 30. Each row of the second element rows 32 comprises a plurality of elements arranged side by side from front to back along the longitudinal direction of the zipper.The second slider 33 is movably attached to the left second element row 32 and aligned in the front-back direction with the second retaining pin 35. Furthermore, the second zipper element 30 also includes a third magnetic body 37 and a fourth magnetic body 38, wherein the third magnetic body 37 and the fourth magnetic body 38 are each attached to the second retaining pin 35 and the second separating pin 36, respectively, thereby magnetically coupling the second retaining pin 35 and the second separating pin 36 during engagement.

[0031] As in the Fig. As shown in Figures 1 to 3, in the zipper device 10 according to the present application, the distal end of the first zipper element 20 and the distal end of the second zipper element 30 abut each other in the front-back direction, i.e., the first separating insert 24 on the first zipper element 20 is located on the back, while the second separating insert 34 on the second zipper element 30 is located on the front. By this arrangement, both the first separating insert 24 and the second separating insert 34 are located in non-end positions on the zipper device 10 in the longitudinal direction; that is, the first separating insert 24 and the second separating insert 34 are not located at the front end or the rear end of the zipper device 10, but rather in an intermediate region of the zipper device 10 or in a region near the intermediate region.Therefore, the first separating insert 24 or the second separating insert 34 is positioned centrally or approximately centrally in the longitudinal direction on the zipper device 10.

[0032] The present utility model further provides for an article as described in the Fig. Figures 13 to 16 illustrate the article, which comprises a first part 71 and a second part 72, which are arranged to be separated and engaged, and the zipper device 10 described above. The first part 71 and the second part 72 are arranged on the left and right sides of the zipper device 10, respectively, along the width direction of the zipper device 10. The first fabric strip 21 and the second fabric strip 31 on the left side of the zipper device 10, in the width direction, are both sewn and attached to an inner edge of the first part 71, and the first fabric strip 21 and the second fabric strip 31 on the right side of the zipper device 10, in the width direction, are both sewn and attached to an inner edge of the second part 72. The first part 71 and the second part 72 are separated and engaged by the zipper device 10.

[0033] Since the zipper device 10 according to the present application has a structure in which the distal end of the first zipper element 20 and the distal end of the second zipper element 30 abut each other in the front-back direction, the first separating insert 24 and the second separating insert 34 are both provided at non-end positions on the zipper device 10 along the longitudinal direction at the distal end of the first zipper element 20 and at the distal end of the second zipper element 30, respectively, thereby preventing the first separating insert 24 or the second separating insert 34 from being located at the end along the longitudinal direction of the article, such as a coat or trousers, after the zipper device 10 has been attached to the article.Instead, the first separating insert 24 or the second separating insert 34 is provided in the intermediate area or in the area near the intermediate area along the longitudinal direction of the article, such as a coat or trousers, thereby facilitating the engagement process between the first retaining pin 25 and the first separating pin 26 as well as the engagement process between the second retaining pin 35 and the second separating pin 36.During the engagement process, the first retaining pin 25 and the first separating pin 26 are magnetically coupled via the first magnetic body 27 and the second magnetic body 28, thereby facilitating the engagement process of the first retaining pin 25 and the first separating pin 26, and similarly, the second retaining pin 35 and the second separating pin 36 are magnetically coupled during the engagement process via the third magnetic body 37 and the fourth magnetic body 38, thereby facilitating the engagement process of the second retaining pin 35 and the second separating pin 36.

[0034] If, for example, the zipper device 10 is attached to the one in Fig. 13 or Fig. As the coat shown in Figure 14 is attached, the first separating insert 24 and the second separating insert 34 in the zipper device 10 are both in the middle position of the coat and not at the top or bottom of the coat. When the zipper device 10 is used to close the coat, first the first slider 23 is pulled to the first separating insert 24 and the second slider 33 is pulled to the second separating insert 34. Then the first separating pin 26 is inserted to the left into the first retaining pin 25 until the first separating pin 26 and the first retaining pin 25 engage, and the second separating pin 36 is inserted to the left into the second retaining pin 35 until the second separating pin 36 and the second retaining pin 35 engage. After that, the first slider 23 is pulled away from the first separating insert 24 to close the first zipper element 20.and the second slider 33 is pulled away from the second divider 34 to close the second zipper element 30. Once both the first zipper element 20 and the second zipper element 30 are closed, the zipper device 10 is fully closed, thus joining the left and right parts of the coat. Since both the first divider 24 and the second divider 34 are positioned in the center of the coat, they are both within easy reach of the wearer's hands and are also within the wearer's optimal field of vision.which facilitates the engagement of the first separating pin 26 and the first retaining pin 25 as well as the engagement of the second separating pin 36 and the second retaining pin 35, and at the same time, at the beginning of the closing process of the zipper device 10, both the first slider 23 and the second slider 33 are positioned in the middle position of the coat and are both located near the wearer's hands and in the wearer's optimal field of vision, so that after the engagement of the first separating pin 26 and the first retaining pin 25 as well as after the engagement of the second separating pin 36 and the second retaining pin 35, the wearer can easily pull the first slider 23 and the second slider 33 to close the zipper device 10.

[0035] Another example: If the zipper device 10 is attached to the one in Fig. As the trouser leg is attached as shown in Figure 15, the first separating insert 24 and the second separating insert 34 in the zipper device 10 are both located in the middle of the trouser leg and not at the top or bottom of the trouser leg. The top of the trouser leg is the waist area, and the bottom of the trouser leg is the ankle area. When the zipper device 10 is used to close the trouser leg, the wearer can therefore easily engage the first separating insert 24 and the second separating insert 34, which are located in the middle of the trouser leg. If the first separating insert 24 and the second separating insert 34 are positioned at the top of the trouser leg, the wearer must lift the garment. If the first separating insert 24 and the second separating insert 34 are positioned at the bottom of the trouser leg, the wearer must squat down.Therefore, the present application allows convenient engagement of the first separating insert 24 and the second separating insert 34 and facilitates the pulling of the first slider 23 and the second slider 33 to close the zipper device 10 without the wearer having to lift the outer garment or squat down.

[0036] Another example: If the zipper device 10 is attached to the in Fig. As shown in Figure 16, the first divider 24 and the second divider 34 are attached to the bag in the zipper device 10, both in the middle position of the bag's opening and not at either end. This provides more working space in the middle position of the bag when closing it with the zipper device 10 than at either end, and this space is not affected by the bag's physical structure, making it very easy to insert the first divider 24 and the second divider 34.

[0037] Furthermore, as in the Fig. Figures 1 and 13 to 16 show the first zipper element 20 and the second zipper element 30 as two zipper elements of the same size and specifications. The length, width, and thickness of the first zipper element 20 and the second zipper element 30 are each identical, and the first zipper element 20 and the second zipper element 30 are arranged symmetrically in the front-to-back direction. This positions both the first separating insert 24 and the second separating insert 34 precisely at the intermediate position on the zipper device 10 along the longitudinal direction. This not only facilitates the engagement between the first retaining pin 25 and the first separating pin 26, as well as the engagement between the second retaining pin 35 and the second separating pin 36, but also improves the aesthetic appearance of the zipper device 10.

[0038] Furthermore, in the zipper device 10, the first fabric strip 21 and the second fabric strip 31 are woven, knitted, or both types of fabric products; the elements of the first element row 22 and the elements of the second element row 32 are nylon, resin, or metal elements; and the first slider 23 and the second slider 33 are plastic or metal sliders. The first slider 23 and the second slider 33 have the same structure as in the Fig. 6 and Fig. Figure 7 shows the first slide 23 and the second slide 33 each comprising an upper leaf 81 and a lower leaf 82, which are arranged opposite each other and connected to one another, a connecting column section 83 connected between the upper leaf 81 and the lower leaf 82, a mounting column section 84 attached to a top surface of the upper leaf 81, and a pull tab 85 rotatably attached to the mounting column section 84. The user can conveniently pull the first slide 23 and the second slide 33 forward or backward by holding the pull tab 85. Element guide channels 86 extending in the front-back direction are formed between the upper leaf 81, the lower leaf 82, and the connecting column section 83.The element guide channel 86 of the first slide 23 allows the passage of the first element row 22, and the element guide channel 86 of the second slide 33 allows the passage of the second element row 32.

[0039] Furthermore, the first retaining pin 25 and the second retaining pin 35 have the same structure, and the first separating pin 26 and the second separating pin 36 also have the same structure. As in Fig. As shown in Figure 4, the first retaining pin 25 and the second retaining pin 35 each comprise a retaining pin base provided at the distal end and a retaining pin column section 91 extending from the retaining pin base in a direction away from the distal end. The right side of the retaining pin column section 91 is provided with an engagement recess 92 having a right-facing opening. The retaining pin base of the first retaining pin 25 is defined as the first retaining pin base 251, and the retaining pin base of the second retaining pin 35 is defined as the second retaining pin base 351. As shown in Fig. As shown in Figure 5, both the first separating pin 26 and the second separating pin 36 comprise a separating pin base provided at the distal end and a separating pin column section 110 extending from the separating pin base in a direction away from the distal end. The separating pin base of the first separating pin 26 is defined as the first separating pin base 261, and the separating pin base of the second separating pin 36 is defined as the second separating pin base 361. When the first retaining pin 25 engages with the first separating pin 26, the first retaining pin base 251 and the first separating pin base 261 overlap and engage with each other in an up-down direction along the thickness direction of the first zipper element 20, and the left part of the separating pin column section 110 of the first separating pin 26 engages in the engagement recess 92 of the first retaining pin 25.The separating pin column section 110 of the first separating pin 26 and the engagement recess 92 of the first retaining pin 25 interlock in the width direction of the first zipper element 20. Similarly, when the second retaining pin 35 engages with the second separating pin 36, the second retaining pin base 351 and the second separating pin base 361 overlap and engage with each other in the up-down direction along the thickness direction of the second zipper element 30, and the left part of the separating pin column section 110 of the second separating pin 36 engages in the engagement recess 92 of the second retaining pin 35, i.e., the separating pin column section 110 of the second separating pin 36 and the engagement recess 92 of the second retaining pin 35 interlock in the width direction of the second zipper element 30.

[0040] A preferred arrangement of the first magnetic body 27 and the second magnetic body 28 in the first zipper element 20 is, as shown in Fig. 8 or Fig. As shown in Figure 9, the first magnetic body 27 is fixed in the first retaining pin base 251 and the second magnetic body 28 in the first separating pin base 261. The magnetic poles of the first magnetic body 27 and the second magnetic body 28, which are opposite each other in an overlap direction of the first retaining pin base 251 and the first separating pin base 261 (i.e., the thickness direction of the first zipper element 20), have opposite polarities, so that the first retaining pin base 251 and the first separating pin base 261 are magnetically coupled by the first magnetic body 27 and the second magnetic body 28, thereby providing a positioning for the engagement of the first retaining pin 25 and the first separating pin 26 and further facilitating the engagement of the first retaining pin 25 and the first separating pin 26. Similarly, a preferred arrangement of the third magnetic body 37 and the fourth magnetic body 38 in the second zipper element 30, as shown in Figure 9, is shown in Figure 9. Fig. 8 or Fig. Figure 9 shows the third magnetic body 37 attached to the second retaining pin base 351 and the fourth magnetic body 38 attached to the second separating pin base 361. The magnetic poles of the third magnetic body 37 and the fourth magnetic body 38, which are opposite each other in an overlap direction of the second retaining pin base 351 and the second separating pin base 361 (i.e., the thickness direction of the second zipper element 30), have opposite polarities, so that the second retaining pin base 351 and the second separating pin base 361 are magnetically coupled by the third magnetic body 37 and the fourth magnetic body 38, thereby providing a positioning for the engagement of the second retaining pin 35 and the second separating pin 36 and further facilitating the engagement of the second retaining pin 35 and the second separating pin 36. Preferably, the first magnetic body 27, the second magnetic body 28, the third magnetic body 37, and the fourth magnetic body 38 are all magnets.

[0041] Furthermore, along the longitudinal direction of the zipper device 10, the first retaining pin base 251 and the second retaining pin base 351 are arranged opposite each other in the front-back direction, the first separating pin base 261 and the second separating pin base 361 are arranged opposite each other in the front-back direction, and in particular, the magnetic poles of the first magnetic body 27 and the third magnetic body 37, which are opposite each other in the longitudinal direction of the zipper device 10, have opposite polarities, and the magnetic poles of the second magnetic body 28 and the fourth magnetic body 38, which are opposite each other in the longitudinal direction of the zipper device 10, have opposite polarities. Based on this, the magnetic poles of the first magnetic body 27, the second magnetic body 28, the third magnetic body 37, and the fourth magnetic body 38 are arranged as follows: As shown in Fig. As shown in Figure 8, the first magnetic body 27 has its N pole at the top and its S pole at the bottom, the second magnetic body 28 has its N pole at the top and its S pole at the bottom, the third magnetic body 37 has its S pole at the top and its N pole at the bottom, and the fourth magnetic body 38 has its S pole at the top and its N pole at the bottom. Alternatively, the magnetic poles of the first magnetic body 27, the second magnetic body 28, the third magnetic body 37, and the fourth magnetic body 38 are arranged as follows: As in Fig. As shown in Figure 9, the first magnetic body 27 has its S pole at the top and its N pole at the bottom, the second magnetic body 28 has its S pole at the top and its N pole at the bottom, the third magnetic body 37 has its N pole at the top and its S pole at the bottom, and the fourth magnetic body 38 has its N pole at the top and its S pole at the bottom. In this arrangement, the first magnetic body 27 and the second magnetic body 28 attract each other in an up-down direction, thereby achieving magnetic coupling between the first retaining pin 25 and the first separating pin 26. The third magnetic body 37 and the fourth magnetic body 38 attract each other in an up-down direction, thereby achieving magnetic coupling between the second retaining pin 35 and the second separating pin 36. Simultaneously, the first magnetic body 27 and the third magnetic body 37 attract each other in a front-back direction, and the second magnetic body 28 and the fourth magnetic body 38 attract each other in a front-back direction.so that the first retaining pin base 251 and the second retaining pin base 351 tend to approach each other along the longitudinal direction of the zipper device 10, and the first separating pin base 261 and the second separating pin base 361 also tend to approach each other along the longitudinal direction of the zipper device 10, thereby reducing the gap at the butt joint between the first zipper element 20 and the second zipper element 30 of the zipper device 10, or in other words, preventing the repulsion between the first magnetic body 27 and the third magnetic body 37, as well as the repulsion between the second magnetic body 28 and the fourth magnetic body 38, from creating an additional gap at the butt joint between the first zipper element 20 and the second zipper element 30.which improves the aesthetic appearance of the zipper device 10 and improves the integrity of the first zipper element 20 and the second zipper element 30 in the closed state.

[0042] Furthermore, the zipper device comprises 10, as shown in Fig. Figure 3 shows a lining fabric 40. The lining fabric 40 is arranged on the back side of the distal end joint between the first zipper element 20 and the second zipper element 30. An outer edge of the lining fabric 40 in the width direction of the zipper device 10 is attached to the first fabric strip 21 and / or the second fabric strip 31, thereby fixing the lining fabric 40 to the zipper device 10. In the Fig. In the embodiment shown in Figure 3, the right outer edge of the lining fabric 40 is attached to the right first fabric band 21 of the first zipper element 20 and the right second fabric band 31 of the second zipper element 30.Of course, in other embodiments, the right outer edge of the lining fabric 40 can be attached only to the right first fabric strip 21 of the first zipper element 20, or the right outer edge of the lining fabric 40 can be attached only to the right second fabric strip 31 of the second zipper element 30, or the left outer edge of the lining fabric 40 can be attached to the left first fabric strip 21 of the first zipper element 20 and the left second fabric strip 31 of the second zipper element 30, or the left outer edge of the lining fabric 40 can be attached only to the left first fabric strip 21 of the first zipper element 20, or the left outer edge of the lining fabric 40 can be attached only to the left second fabric strip 31 of the second zipper element 30.The fastening method between the lining fabric 40 and the first fabric strip 21 and / or the second fabric strip 31 includes, among other things, fastening by sewing and fastening with adhesive. The lining fabric 40 covers the gap at the distal end butt joint between the first zipper element 20 and the second zipper element 30, which, on the one hand, improves the aesthetic appearance of the zipper device 10 and enhances the integrity of the first zipper element 20 and the second zipper element 30 when closed, and, on the other hand, can block the gap at the butt joint between the first zipper element 20 and the second zipper element 30, thus preventing internal parts of an article equipped with the zipper device 10 from being exposed through this gap.

[0043] Furthermore, in other embodiments of the zipper device 10, as in Fig. 10 or Fig. Figure 11 shows the zipper device 10 further comprising a first handle 50 and a second handle 60, which are arranged opposite each other along the width direction of the zipper device 10, wherein the first handle 50 and the second handle 60 are both arranged at the distal end of the butt joint of the first zipper element 20 and the second zipper element 30, the first handle 50 being attached directly or indirectly to the first fabric strip 21 and / or the second fabric strip 31 on one side in the width direction of the zipper device 10, and the second handle 60 being attached directly or indirectly to the first fabric strip 21 and / or the second fabric strip 31 on another side in the width direction of the zipper device 10.To open the zipper device 10, first pull the first slider 23 to the distal end of the first zipper element 20 and the second slider 33 to the distal end of the second zipper element 30, then hold the first handle 50 and the second handle 60 firmly and exert an outward force along the width direction of the zipper device 10, whereby the force is transmitted via the first fabric band 21 to the first retaining pin 25 and the first separating pin 26 and via the second fabric band 31 to the second retaining pin 35 and the second separating pin 36, so that the first retaining pin 25 and the first separating pin 26 can be easily separated from each other and the second retaining pin 35 and the second separating pin 36 can be easily separated from each other, thus facilitating the opening of the zipper device 10.When closing the zipper device 10, holding the first handle 50 and the second handle 60 allows the first retaining pin 25 and the first separating pin 26 to be easily brought together, and the second retaining pin 35 and the second separating pin 36 to be easily brought together. Combined with the magnetic coupling of the first retaining pin 25 and the first separating pin 26, as well as the magnetic coupling of the second retaining pin 35 and the second separating pin 36, the first retaining pin 25 and the first separating pin 26 can be more easily engaged, and the second retaining pin 35 and the second separating pin 36 can be more easily engaged, thus allowing the zipper device 10 to be conveniently closed.

[0044] Furthermore, there are various arrangement methods and shapes for the first handle 50 and the second handle 60. For example, in the Fig. In the zipper device 10 shown, both the first pull 50 and the second pull 60 are curved, for example, arc-shaped or U-shaped. Both ends of the first pull 50 are fixed longitudinally to the first part 71 of the article, and the fastening method includes, but is not limited to, sewing or adhesive fastening, and the fastening point is located near the first fabric strip 21 and the second fabric strip 31 on the left side of the butt joint between the first zipper element 20 and the second zipper element 30, and the first fabric strip 21 and the second fabric strip 31 on the left side are fixedly connected to the first part 71 of the article, thereby achieving the fixed connection between the first pull 50 and the first fabric strip 21 on the left side and between the first pull 50 and the second fabric strip 31 on the left side.Both ends of the second handle 60 in the longitudinal direction are firmly connected to the second part 72 of the article, and the fastening method includes, but is not limited to, a sewing fastening or a fastening with adhesive, and the fastening point is located near the first fabric strip 21 and the second fabric strip 31 on the right side of the butt joint between the first zipper element 20 and the second zipper element 30, and the first fabric strip 21 and the second fabric strip 31 on the right side are firmly connected to the second part 72 of the article, thereby achieving the firm connection between the second handle 60 and the first fabric strip 21 on the right side and between the second handle 60 and the second fabric strip 31 on the right side.Of course, in other embodiments, both ends of the first handle 50 can be attached longitudinally directly to the first fabric strip 21 and the second fabric strip 31 on the left side of the zipper device 10 in the width direction, and both ends of the second handle 60 can each be attached longitudinally directly to the first fabric strip 21 and the second fabric strip 31 on the right side of the zipper device 10 in the cross direction. The methods for attaching the first handle 50 to the first fabric strip 21 and the second fabric strip 31, as well as the methods for attaching the second handle 60 to the first fabric strip 21 and the second fabric strip 31, include, but are not limited to, attachment by sewing and attachment with adhesive.

[0045] In another example, which in Fig. In the zipper device 10 shown in Figure 11, the first pull 50 and the second pull 60 are both straight, and both are attached to the front of the article equipped with the zipper device 10. The first fabric strip 21 and the second fabric strip 31 are also attached to the article, thereby achieving a firm connection between the first pull 50 and the first fabric strip 21, as well as between the first pull 50 and the second fabric strip 31, and between the second pull 60 and the first fabric strip 21, as well as between the second pull 60 and the second fabric strip 31. Preferably, if both the first pull 50 and the second pull 60 are attached to the front of the article, as shown in Figure 11, the zipper device 10 is attached to the front of the article. Fig. As shown in Figure 11, an edge of at least one of the first handles 50 and the second handles 60 is not attached to the article, for example, in Fig. 11 the lower edge of the first handle 50 and the lower edge of the second handle 60 not attached to the article, in another example in Fig. In one example, the top and bottom edges of the first handle 50 and the top and bottom edges of the second handle 60 are not attached to the article. In another example, the top edges of the first handle 50 and the second handle 60 are not attached to the article, forming a hand insertion opening between the first handle 50 and the article and between the second handle 60 and the article. At this point, the first handle 50 and the second handle 60 both have a pocket-like shape, which makes it convenient for the user to hold the first handle 50 and the second handle 60 through the hand opening and then to exert force to pull and separate the first separating insert 24 and the second separating insert 34.

[0046] In another example in the Fig. In the zipper device 10 shown in Figure 12, the first pull 50 and the second pull 60 are both concave, and the fastening method of the first pull 50 and the second pull 60 is the same as the fastening method of the first pull 50 and the second pull 60 in the Fig. The zipper device shown in section 10 is not repeated here.

[0047] Preferably, the first handle 50 and the second handle 60 can additionally be configured as handle components; alternatively, the first handle 50 and the second handle 60 can also be implemented by existing handle components in the article. For example, in the case of the Fig. 14 depicted coat a pair of pockets of the coat the first handle 50 and the second handle 60, and at the in Fig. The 16 depicted bags form a pair of handles of the bag, the first handle 50 and the second handle 60.
