Description

Technical Field

[0001] The present invention relates to the technology in the field of zippers, and particularly to a slider and a fastener. Background Art

[0002] Common zippers usually include a fastener chain composed of a pair of fastener stringers each consisting of a strip-shaped fastener tape and a plurality of element columns arranged on the fastener tape, and a slider installed on the fastener stringer to open or close the element columns by sliding, and a tab pull can also be provided on the slider according to requirements. Among them, when the slider is installed on the fastener stringer, the element columns on the fastener stringer pass through the element channel formed between the lower wing plate and the upper wing plate of the slider, and are opened or closed under the guidance of the guiding post of the slider during the sliding process of the slider. During this process, the inner edge of the fastener tape is likely to abut against the side surface of the guiding post of the slider to generate friction, resulting in easy damage to the fastener tape. Moreover, when a waterproof layer is provided on the surface of the fastener tape to make the fastener tape thicker, the sliding resistance received by the slider during the sliding process also becomes larger, making it difficult to smoothly perform the opening and closing operations. Thus, it is necessary to improve the structures of the slider and the fastener. Summary of the Invention

[0003] The present invention provides a slider and a fastener, which can improve the smoothness of the slider when sliding on the fastener stringer, thereby reducing the damage of the fastener stringer and having good operability.

[0004] The present invention provides a slider, which is suitable for being installed on a pair of fastener stringers to form a fastener, and includes: a lower wing plate; an upper wing plate oppositely disposed above the lower wing plate; a guiding post disposed between the lower wing plate and the upper wing plate and connecting the front end portions in the front-rear direction of the lower wing plate and the upper wing plate; and a pair of flanges respectively disposed on the opposite side edges in the width direction of one of the lower wing plate and the upper wing plate and extending towards the other of the lower wing plate and the upper wing plate, wherein the inner side surface of the other of the lower wing plate and the upper wing plate and the end surface of the flange are opposite to each other and spaced apart by a gap, a first groove is provided on the side surface of the guiding post, and the first groove corresponds to the gap in the up-down direction.

[0005] In an embodiment of the present invention, the slider further includes: a tab mounting post disposed above the upper wing plate, and the first groove is provided at one end of the guiding post close to the tab mounting post.

[0006] In an embodiment of the present invention, the first grooves are provided on opposite side surfaces of the guide post in the width direction.

[0007] In an embodiment of the present invention, the first grooves are provided on the rear side surface of the guide post in the front-rear direction.

[0008] In an embodiment of the present invention, a second groove is provided on the inner side surface of the upper wing plate facing the lower wing plate, and the second groove is located at a position on the inner side surface of the upper wing plate close to the guide post.

[0009] In an embodiment of the present invention, the front edge of the front end portion of the lower wing plate is more rearward in the front-rear direction than the front edge of the front end portion of the upper wing plate. The guide post connects the front edge of the lower wing plate and the front end portion of the upper wing plate, and there is a distance between the guide post and the front edge of the upper wing plate. A retraction portion is formed between the front side of the guide post and the front edge of the upper wing plate.

[0010] In an embodiment of the present invention, the lower wing plate has a front edge at the front end portion and a pair of shoulder side edges respectively extending rearward from the front edge on opposite sides in the width direction. The front edge is configured as an arc protruding outward, and the shoulder side edges are configured as arcs recessed inward, and avoidance portions are formed on opposite sides of the lower wing plate in the width direction.

[0011] In an embodiment of the present invention, the upper wing plate has a front edge at the front end portion and a pair of shoulder side edges respectively extending rearward from the front edge on opposite sides in the width direction. The front edge is configured as an arc protruding outward, and the shoulder side edges are configured as arcs protruding outward.

[0012] In an embodiment of the present invention, the upper wing plate has a front edge at the front end portion, a pair of shoulder side edges respectively extending rearward from the front edge on opposite sides in the width direction, and a rear side edge more rearward than the shoulder side edges in the front-rear direction. The front edge and the rear side edge are each configured as a straight line extending in the width direction, and the pair of shoulder side edges are configured as straight lines extending in the front-rear direction.

[0013] The present invention also provides a zipper, comprising: a pair of zipper teeth tapes; and the slider mounted on the pair of zipper teeth tapes to open or close the pair of zipper teeth tapes, wherein the zipper teeth tape includes a zipper tape and a coil tooth row mounted on a first surface of the zipper tape, a boundary between the first groove and a side surface of the guiding post forms a stepped portion, and the stepped portion is located between a second surface of the zipper tape opposite to the first surface and an end surface of the coil tooth row opposite to the zipper tape.

[0014] Based on the above, in the slider of the present invention, one of the lower wing plate and the upper wing plate is provided with a pair of flanges on opposite side edges in the width direction, an inner side surface of the other of the lower wing plate and the upper wing plate and an end surface of the flange face each other and are spaced apart by a gap, and a first groove corresponding to the gap in the up-and-down direction is provided on the side surface of the guiding post. When the slider is mounted on the zipper teeth tape to form a zipper, an outer edge of the zipper tape passes through the gap of the slider and an inner edge of the zipper tape corresponds to the first groove provided on the side surface of the guiding post of the slider. Thus, the provision of the first groove can reduce the friction between the inner edge of the zipper tape and the side surface of the guiding post, and reduce the sliding resistance of the slider on the zipper teeth tape. Accordingly, the slider and the zipper of the present invention can improve the smoothness of the slider when sliding on the zipper teeth tape, thereby reducing the damage of the zipper teeth tape and having good operability.

[0015] To make the above features and advantages of the present invention more obvious and understandable, the following specific embodiments are given and described in detail in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Among them, Figure 1 is a perspective view of a slider according to an embodiment of the present invention, Figure 2 is Figure 1 a perspective view of the slider shown in other perspectives, Figure 3 is Figure 1 a front view of the slider shown, Figure 4 is Figure 1 a side view of the slider shown, Figure 5 is according to an embodiment of the present invention with Figure 1Three - dimensional schematic diagram of a zipper with a slider Figure 6 is Figure 5 the side - view schematic diagram of the zipper shown Figure 7 is Figure 5 the rear - view schematic diagram of the zipper shown Figure 8 is Figure 5 the front - view schematic diagram of the zipper shown Figure 9 is a side - view schematic diagram of a double - open - end zipper with sliders having two Figure 1 in accordance with another embodiment of the present invention Figure 10 is Figure 1 the three - dimensional schematic diagram of the first variant of the slider shown Figure 11 is Figure 1 the cross - sectional schematic diagram of the slider shown after cutting the guide post along the front - to - rear direction Figure 12 is Figure 1 the side - view schematic diagram of the second variant of the slider shown Figure 13 is Figure 1 the three - dimensional schematic diagram of the third variant of the slider shown from other perspectives. The following will be described in conjunction with Figures 1 to 13 the specific structures of the slider 100, the zipper tape 50 used, and the zipper 20 formed in an embodiment of the present invention, as well as its variants, etc. However, the present invention is not limited thereto, and it can be adjusted according to requirements.

[0065] Please refer to Figures 1 to 5 , in this embodiment, the slider 100 is suitable for being installed on a pair of zipper tapes 50 to form a zipper 20. The zipper 20 includes a pair of zipper tapes 50 and a slider 100. The slider 100 is installed on a pair of zipper tapes 50 to open or close the pair of zipper tapes 50. Among them, the zipper tape 50, for example, includes a zipper band 52 and a coil chain tooth row 54 installed on the first surface 52a of the zipper band 52 (as Figure 5 shown). The second surface 52b of the zipper band 52 opposite to the first surface 52a is not provided with a coil chain tooth row 54, and a bonding layer such as a waterproof film (not shown) can be provided according to requirements. However, the present invention does not limit whether a bonding layer is provided on the second surface 52b. Furthermore, although this embodiment takes the zipper tape 50 having a coil chain tooth row 54 as an example for description, the present invention does not limit the type of the zipper tape 50 to which the slider 100 can be applied, and it can also be applied to zipper tapes with other types of chain tooth rows.

[0066] Specifically, in this embodiment, as Figures 1 to 4As shown, the slider 100 includes a lower wing plate 110, an upper wing plate 120, a guide post 130, and a pair of flanges (for example, the lower flange 140 described later). The lower wing plate 110 and the upper wing plate 120 are each configured as plate-like members, and the upper wing plate 120 is disposed opposite above the lower wing plate 110. The guide post 130 is disposed between the lower wing plate 110 and the upper wing plate 120 and connects the front end portions E1 in the front-rear direction (i.e., the longitudinal direction L) of the lower wing plate 110 and the upper wing plate 120. Accordingly, the rear end portions E2 in the front-rear direction (i.e., the longitudinal direction L) of the lower wing plate 110 and the upper wing plate 120 are configured to be in an open state. Thus, a tooth channel 102 for passing a pair of zipper tooth tapes 50 is formed between the lower wing plate 110 and the upper wing plate 120 and on opposite sides of the guide post 130 in the left-right direction (i.e., the width direction W).

[0067] Furthermore, in the present embodiment, as Figures 1 to 4 shown, a pair of flanges (for example, the lower flange 140) are respectively disposed on opposite side edges in the width direction W of one of the lower wing plate 110 and the upper wing plate 120 (for example, the lower wing plate 110) and extend toward the other of the lower wing plate 110 and the upper wing plate 120 (for example, the upper wing plate 120). That is, the flanges are the lower flanges 140 disposed on opposite side edges in the width direction W of the lower wing plate 110 in the present embodiment. Accordingly, a pair of upper flanges 150 may be correspondingly provided on opposite side edges in the width direction W of the upper wing plate 120 of the present embodiment. The upper flanges 150 and the aforementioned lower flanges 140 are opposite to each other in the up-down direction (i.e., the thickness direction T). However, in other embodiments not shown, only a pair of lower flanges 140 on the lower wing plate 110 may be provided, or only a pair of upper flanges 150 on the upper wing plate 120 may be provided. As long as one of the lower wing plate 110 and the upper wing plate 120 is provided with flanges. Thus, a pair of flanges (for example, the lower flanges 140 and / or the upper flanges 150) are located outside the aforementioned tooth channel 102, so that the coil tooth rows 54 of the pair of zipper tooth tapes 50 can be restricted in the tooth channel 102, enabling the slider 100 to open or close the coil tooth rows 54 on the zipper tooth tape 50. However, the present invention does not limit the number, position, and arrangement manner of the flanges, which can be adjusted according to requirements.

[0068] Furthermore, in the present embodiment, as Figure 3 and Figure 4As shown, when a pair of flanges (i.e., the lower flange 140 and the upper flange 150) are respectively provided on the lower wing plate 110 and the upper wing plate 120, the end face of the lower flange 140 on the lower wing plate 110 and the end face of the upper flange 150 on the upper wing plate 120 face each other with a gap G therebetween. That is, the end faces of the lower flange 140 and the upper flange 150 are separated from each other and do not contact. The gap G refers to the space between the end face of the lower flange 140 on the lower wing plate 110 and the end face of the upper flange 150 on the upper wing plate 120. Thus, when the slider 100 is installed on the zipper tape 50 to form the zipper 20, as Figure 5 as Figure 6 shown, the outer edges of the zipper tapes 52 of the pair of zipper tapes 50 can extend outward from the gap G, enabling the slider 100 to slide on the zipper tapes 52 of the zipper tape 50 in a manner of being mounted on the coil chain teeth row 54, thereby opening or closing the coil chain teeth row 54. In the case where a pair of flanges (e.g., the lower flange 140) are provided on only one of the lower wing plate 110 and the upper wing plate 120 (for example, the lower wing plate 110) (not shown), the inner side surface of the other of the lower wing plate 110 and the upper wing plate 120 (for example, the upper wing plate 120) and the end face of the flange (i.e., the lower flange 140) face each other with a gap G therebetween. However, the present invention does not limit the setting manner of the flanges and the position of the gap G, which can be adjusted according to requirements.

[0069] As an example, as Figure 3 as Figure 4 shown, the dimension (height) of the lower flange 140 in the up-and-down direction (i.e., the thickness direction T) is greater than the dimension (height) of the upper flange 150 in the up-and-down direction (i.e., the thickness direction T), so that the gap G is closer to the upper wing plate 120. Thus, when the slider 100 is installed on the zipper tape 50 to form the zipper 20, as Figure 5 as Figure 6As shown, it is preferably installed in such a manner that the coil chain teeth row 54 (i.e., the first surface 52a) provided on the zipper tape 52 faces the lower wing plate 110, so that the coil chain teeth row 54 is limited by the larger-sized lower flange 140. In this case, the coil chain teeth row 54 is hidden inside the zipper tape 52 (i.e., on the side opposite to the upper wing plate 120), so that the zipper 20 can be used as a concealed zipper. In the case where only the lower flange 140 is provided on the lower wing plate 110 (not shown), it is also preferably installed in such a manner that the coil chain teeth row 54 (i.e., the first surface 52a) provided on the zipper tape 52 faces the lower wing plate 110, so that the coil chain teeth row 54 is limited by the lower flange 140. Correspondingly, in the case where the height of the lower flange 140 is less than the height of the upper flange 150 (not shown), or in the case where only the upper flange 150 is provided on the upper wing plate 120 (not shown), it is preferably installed in such a manner that the coil chain teeth row 54 (i.e., the first surface 52a) provided on the zipper tape 52 faces the upper wing plate 120, so that the coil chain teeth row 54 is limited by the upper flange 150. However, the present invention does not limit the position of the gap G and the relative position when the slider 100 is installed on the zipper chain tape 50, which can be adjusted according to requirements.

[0070] Furthermore, in this embodiment, as Figure 3 shown in Figure 4 a first groove 132 is provided on the side surface of the guide post 130, and the first groove 132 corresponds to the gap G in the up and down direction (i.e., the thickness direction T). That is, in the perspective of viewing the slider 100 from the front or from the side, the horizontal height of the first groove 132 in the up and down direction (i.e., the thickness direction T) is substantially the same as that of the gap G in the up and down direction (i.e., the thickness direction T). The first groove 132 forms a depression on the side surface of the guide post 130, so that the dimension of the portion of the guide post 130 provided with the first groove 132 in the width direction W becomes smaller. Thus, when the slider 100 is installed on the zipper chain tape 50 to form the zipper 20, as Figure 5 shown in Figure 6 the outer edges of the zipper tapes 52 of the pair of zipper chain tapes 50 extend outward through the gap G of the slider 100, and the inner edges of the zipper tapes 52 correspond to the first groove 132 on the side surface of the guide post 130 of the slider 100.

[0071] With the above settings, in the slider 100 of the present embodiment, one of the lower wing plate 110 and the upper wing plate 120 (for example, the lower wing plate 110) is provided with a pair of flanges (for example, the lower flange 140) on opposite side edges in the width direction W. The inner surface of the other of the lower wing plate 110 and the upper wing plate 120 (for example, the upper wing plate 120) and the end surface of the flange (for example, the lower flange 140) face each other and are separated by a gap G, and the side surface of the guide post 130 is provided with a first groove 132 corresponding to the gap G in the up and down direction (i.e., the thickness direction T). When the slider 100 is installed on the zipper tooth chain tape 50 to form a zipper 20, the outer edge of the zipper tape 52 passes through the gap G of the slider 100 and the inner edge of the zipper tape 52 corresponds to the first groove 132 provided on the side surface of the guide post 130 of the slider 100. Thus, the setting of the first groove 132 can reduce the friction between the inner edge of the zipper tape 52 and the side surface of the guide post 130, and reduce the sliding resistance of the slider 100 on the zipper tooth chain tape 50. Accordingly, the slider 100 and the zipper 20 can improve the smoothness of the slider 100 when sliding on the zipper tooth chain tape 50, thereby reducing the damage of the zipper tooth chain tape 50 and having good operability.

[0072] Furthermore, in the present embodiment, as Figures 1 to 5 shown, the slider 100 further includes a tab mounting post 160, and the tab mounting post 160 is provided above the upper wing plate 120. And, the first groove 132 is provided at one end of the guide post 130 close to the tab mounting post 160 (i.e., the end close to the upper wing plate 120 in the thickness direction T). Thus, when the slider 100 is installed on the zipper tooth chain tape 50 to form a zipper 20, as Figure 5 and Figure 6 shown, the slider 100 preferably uses the upper wing plate 120 provided with the tab mounting post 160 as the operation appearance surface, and the zipper tooth chain tape 50 is installed in such a way that the coil chain tooth row 54 (i.e., the first surface 52a) provided on the zipper tape 52 faces the lower wing plate 110, so that the coil chain tooth row 54 is hidden inside the zipper tape 52 (i.e., on the side opposite to the upper wing plate 120), so that the zipper 20 can be used as a concealed zipper. At this time, the outer edge of the zipper tape 52 passes through the gap G close to the upper wing plate 120 and the inner edge of the zipper tape 52 corresponds to the first groove 132 close to the upper wing plate 120. Thus, during the process of the slider 100 sliding relative to the zipper tooth chain tape 50, the zipper tape 52 does not need to be bent significantly in the up and down direction (i.e., the thickness direction T), so that the sliding resistance of the slider 100 on the zipper tooth chain tape 50 can be reduced. However, in other embodiments not shown, the tab mounting post 160 can also be omitted, and the lower wing plate 110 can also be used as the operation appearance surface. The present invention is not limited thereto and can be adjusted according to requirements.

[0073] In addition, in the present embodiment, asFigures 3 to 6 As shown, the first groove 132 extends from the junction of the guide post 130 and the upper wing plate 120 toward the lower wing plate 110. Thus, the dimension (width) in the width direction W of the upper end portion of the guide post 130 near the upper wing plate 120 is smaller than the dimension (width) in the width direction W of the lower end portion near the lower wing plate 110, and the boundary between the first groove 132 and the side surface of the guide post 130 (for example, the lower end surface of the first groove 132) forms a stepped portion 134. In this case, if the stepped portion 134 is located at a position higher than the second surface 52b of the zipper tape 52 in the up-down direction (i.e., the thickness direction T), that is, if the size of the first groove 132 is too small and the first groove 132 is located at a position higher than the inner edge of the zipper tape 52, the inner edge of the zipper tape 52 contacts the side surface or the stepped portion 134 of the guide post 130, and the zipper tape 52 is liable to be damaged by friction. In particular, when a bonding layer such as a waterproof film (not shown) is provided on the second surface 52b of the zipper tape 52, the bonding layer is liable to peel off due to friction, and a problem of reduced waterproofness occurs. Similarly, if the stepped portion 134 is located at a position lower than the end surface (i.e., the lower end surface 54a) of the coil chain teeth row 54 opposite to the zipper tape 52 in the up-down direction (i.e., the thickness direction T), that is, if the size of the first groove 132 is too large and the first groove 132 covers the zipper tape 52 and the coil chain teeth row 54, the side surface of the guide post 130 cannot effectively guide and limit the coil chain teeth row 54, and a problem of unstable slider 100 sliding is liable to occur.

[0074] Based on the above considerations, in the present embodiment, the stepped portion 134 formed by the boundary between the first groove 132 and the side surface of the guide post 130 is further set corresponding to the positions of the zipper tape 52 and the coil chain teeth row 54 in the zipper chain tape 50 to which the slider 100 is applied. As an example, as Figure 5 And Figure 6As shown, the step portion 134 is located between the second surface 52b of the zipper tape 52 opposite to the first surface 52a and the end surface (i.e., the lower end surface 54a) of the coil chain teeth row 54 opposite to the zipper tape 52 (i.e., within the range R). From this, it can be known that when the first groove 132 extends from the junction of the guide post 130 and the upper wing plate 120 toward the lower wing plate 110, by designing the setting of the lower end portion of the first groove 132, that is, the step portion 134 in the above manner, it is possible to eliminate the situation where the size of the first groove 132 is too small or too large. In this way, the first groove 132 can better play its role (reduce friction and sliding resistance) through the above setting. Accordingly, the slider 100 and the zipper 20 can reduce the damage of the zipper chain tape 50 and have good operability. However, in other embodiments not shown, the first groove 132 may also be provided at one end of the guide post 130 close to the lower wing plate 110 in the thickness direction T, or may be provided in the middle part of the guide post 130. The present invention is not limited thereto, and it can be adjusted according to requirements.

[0075] In addition, in the present embodiment, as Figure 2 shown in Figure 7 FIG. [FIGURE NUMBER], the lower wing plate 110 has a front edge 112 located at the front end portion E1, and a pair of shoulder side edges 114 extending rearward from the front edge 112 on opposite sides in the width direction W. Among them, the front edge 112 is configured as an arc protruding outward, and the shoulder side edges 114 are configured as arcs concave inward, and avoidance portions 116 are formed on opposite sides in the width direction W of the lower wing plate 110 (as Figure 7 shown in Figure 5 FIG. [FIGURE NUMBER]). Through the above setting, when the slider 100 is mounted on the zipper chain tape 50 to form the zipper 20, as Figure 7 shown in

[0076] FIG. [FIGURE NUMBER], the lower wing plate 110 of the slider 100 corresponds to the first surface 52a of the zipper tape 52 provided with the coil chain teeth row 54. The coil chain teeth row 54 of the zipper chain tape 50 is guided by the guide post 130 of the slider 100 and passes through the chain teeth passage 102, and passes through the avoidance portion 116 formed by the shoulder side edges 114 of the lower wing plate 110 during the sliding process of the slider 100 relative to the zipper chain tape 50. In this way, the avoidance portion 116 formed by the shoulder side edges 114 of the lower wing plate 110 can reduce the friction between the lower wing plate 110 and the lower end surface 54a of the coil chain teeth row 54, and reduce the sliding resistance of the slider 100 on the zipper chain tape 50. Accordingly, the slider 100 and the zipper 20 can reduce the damage of the zipper chain tape 50 and have good operability. However, the present invention does not limit the shape of the lower wing plate 110 (i.e., does not limit the setting of the avoidance portion 116), nor does it limit that the slider 100 can only be applied to the zipper chain tape 50 having the coil chain teeth row 54, and it can be adjusted according to requirements.

[0075] , Figure 2 , Figure 7 , Figure 7 , Figure 5 , Figure 7 , ,

[0076] , Figure 1 with the actual figure numbers in the original patent text, and replace [FIGURE NUMBER] with the corresponding figure numbers in the translated text according to the actual situation.With Figure 8 As shown, the upper wing plate 120 has a front edge 122 at the front end portion E1, a pair of shoulder side edges 124 extending rearward from the front edge 122 on opposite sides in the width direction W, and a rear side edge 126 that is more rearward than the shoulder side edges 124 in the front-rear direction (i.e., the length direction L). Among them, the front edge 122 and the rear side edge 126 are each configured as straight lines extending in the width direction W, and the pair of shoulder side edges 124 are configured as straight lines extending in the front-rear direction (i.e., the length direction L). With the above arrangement, when the slider 100 is mounted on the zipper chain tape 50 to form the zipper 20, as Figure 5 With Figure 8 As shown, the upper wing plate 120 of the slider 100 corresponds to the second surface 52b of the zipper tape 52 where the coil teeth row 54 is not provided. Thus, the substantially rectangular upper wing plate 120 is configured to abut against the second surface 52b of the zipper tape 52, thereby increasing the stability when the slider 100 slides relative to the zipper chain tape 50. Also, the front edge 122 of the upper wing plate 120 of the slider 100 is parallel to the front edge of the zipper tape 52 (extending in the width direction W). Thus, when the zipper chain tape 50 is closed by the slider 100, the front edge 122 of the upper wing plate 120 and the front edge of the zipper tape 52 correspond to each other and further coincide (as Figure 8 shown), and the gap between the slider 100 and the end portion of the zipper chain tape 50 can be reduced, and the aesthetics of the slider 100 with the upper wing plate 120 as the operation appearance surface on the zipper chain tape 50 can be improved.

[0077] Furthermore, in this embodiment, as Figure 4 With Figure 9 As shown, the front edge 112 of the front end portion E1 of the lower wing plate 110 is more rearward in the front-rear direction (i.e., the length direction L) than the front edge 122 of the front end portion E1 of the upper wing plate 120. The guide post 130 connects the front edge 112 of the lower wing plate 110 and the front end portion E1 of the upper wing plate 120, and is spaced apart from the front edge 122 of the upper wing plate 120 by a distance D. A recess portion 136 is formed between the front end side of the guide post 130 and the front edge 122 of the upper wing plate 120. With the above arrangement, when two sliders 100 are mounted on the zipper chain tape 50 to form the double-open-end zipper 20A, as Figure 4 With Figure 9As shown, two sliders 100 are installed in such a way that their front ends E1 face each other. Thus, when the zipper teeth tape 50 is closed by the two sliders 100, the front edge 112 of the lower wing plate 110 of the two sliders 100 abuts against each other, and the front edge 122 of the upper wing plate 120 abuts against each other, so that the gap between the two sliders 100 and the zipper teeth tape 50 can be reduced in the front - rear direction (i.e., the length direction L) and the up - down direction (i.e., the thickness direction T). In particular, when the upper wing plate 120 of the slider 100 has a linear front edge 122 configured to extend in the width direction W as Figure 8 described, the upper wing plates 120 of the two sliders 100 abut against each other with the linear front edges 122, so that the gap between the two sliders 100 and the zipper teeth tape 50 can be reduced in the width direction W and the front - rear direction (i.e., the length direction L), and the aesthetic appearance of the slider 100 with the upper wing plate 120 as the operation appearance surface on the zipper teeth tape 50 can be improved. However, the present invention does not limit that the sliders 100 can only be arranged in pairs, and they can also be arranged singly on the zipper teeth tape 50 as Figure 6 shown, and as Figure 8 shown, the gap between the slider 100 and the end of the zipper teeth tape 50 can be reduced. Also, the present invention does not limit the presence or absence of the retraction portion 136, which can be adjusted according to requirements.

[0078] Accordingly, in the first modification example as Figure 10 shown, the slider 100A has a similar structural configuration to the aforementioned slider 100. The main difference is that the upper wing plate 120A of the slider 100A is different from the upper wing plate 120 of the aforementioned slider 100. Other parts (such as the lower wing plate 110, the guide post 130, the lower flange 140, the upper flange 150, the tab mounting post 160, and the first groove 132, etc.) can refer to the aforementioned description and will not be elaborated here. Specifically, in the modification example as Figure 10 shown, the upper wing plate 120A has a front edge 122A located at the front end E1 and a pair of shoulder - side edges 124A extending rearward from the front edge 122A on opposite sides in the width direction W. Among them, the front edge 122A is configured as an arc protruding outward, and the shoulder - side edges 124A are configured as arcs protruding outward. Through the above - mentioned setting, when the slider 100A is installed on the zipper teeth tape 50 to form the zipper 20, the upper wing plate 120A of the slider 100A can abut against the second surface 52b of the zipper tape 52 with a smaller area, thereby reducing the friction when the slider 100A slides relative to the zipper teeth tape 50. It can be seen that the present invention does not limit the shapes of the upper wing plates 120 and 120A, which can be adjusted according to requirements. As Figure 10The slider 100A in the illustrated modification example can also be provided with a retracted portion 136, and can also be provided in pairs on the zipper chain tape 50 to form a double-open-end zipper 20A. Thus, the gap between the two sliders 100A and the zipper chain tape 50 can also be reduced. However, the present invention does not limit the application of the slider 100A, and it can be adjusted according to requirements.

[0079] Please refer to Figure 4 and Figure 11 , in the present embodiment, the guide post 130 includes a front side surface S1, opposite side surfaces S2, S3 that are separated in the width direction W and parallel to each other, and a pair of inclined rear side surfaces S4, S5, and is configured as a columnar structure with a cross-section substantially presenting a pentagon (diamond shape). As an example, the first groove 132 is provided on the opposite side surfaces S2, S3 of the guide post 130 in the width direction W, and is provided on the rear side surfaces S4, S5 of the guide post 130 in the front-rear direction (i.e., the length direction L) (for example, Figure 11 the dotted area in). That is, the first groove 132 is not provided on the front side surface S1 (because the zipper chain tape 50 does not contact the front side surface S1). Through the above arrangement, when the slider 100 is mounted on the zipper chain tape 50 to form the zipper 20, as Figure 5 and Figure 11 shown, the zipper chain tape 50 is separated from each other by the opposite side surfaces S2, S3 and the rear side surfaces S4, S5 of the guide post 130 during the sliding process of the slider 100. Thus, the setting of the first groove 132 can reduce the friction between the inner edge of the zipper tape 52 and the side surfaces of the guide post 130 (i.e., the opposite side surfaces S2, S3 and the rear side surfaces S4, S5), and reduce the sliding resistance of the slider 100 on the zipper chain tape 50. Accordingly, the slider 100 and the zipper 20 can improve the smoothness of the slider 100 when sliding on the zipper chain tape 50, thereby reducing the damage of the zipper chain tape 50 and having good operability.

[0080] Correspondingly, in the second modification example shown in Figure 12 , the slider 100B has a similar structural configuration to the aforementioned slider 100. The main difference is that the first groove 132B of the slider 100B is not provided on the opposite side surfaces S2, S3 of the guide post 130B in the width direction W (as Figure 12as shown), and is only provided on the rear sides S4, S5 of the guide post 130B in the front-rear direction (i.e., the longitudinal direction L). For other parts (such as the lower wing plate 110, the upper wing plate 120, the lower flange 140, the upper flange 150, and the tab mounting post 160, etc.), reference may be made to the foregoing description, and no further elaboration will be given here. Through the above settings, when the slider 100B is mounted on the zipper tape 50 to form the zipper 20, the zipper tape 50 is separated from each other through the rear sides S4, S5 of the guide post 130B during the sliding process of the slider 100B. In this way, the setting of the first groove 132B can reduce the friction between the inner edge of the zipper tape 52 and the side surface (i.e., the rear sides S4, S5) of the guide post 130B. And, compared with the slider 100 of the foregoing embodiment, although the friction-reducing effect of the slider 100B may be relatively poor, the first groove 132B can be provided within the range that has no influence on the trimming of the guide post 130B in the subsequent process (i.e., the rear sides S4, S5), which is conducive to the subsequent process. However, in other embodiments not shown, the first groove 132 may be provided only on the opposite side surfaces S2, S3, or may be provided on all the side surfaces of the guide post 130 (including the front side S1) to form an annular groove. The present invention does not limit the setting position and size of the first groove 132, and it can be adjusted according to requirements.

[0081] In addition, in the third variant embodiment as shown in Figure 13 the slider 100C has a similar structural configuration to the foregoing slider 100. The main difference is that a second groove 128 is provided on the inner side surface of the upper wing plate 120C of the slider 100C facing the lower wing plate 110, and the second groove 128 is located at a position on the inner side surface of the upper wing plate 120C close to the guide post 130. That is, the second groove 128 is provided on the upper wing plate 120C at a position close to the first groove 132, so that the first groove 132 and the second groove 128 correspond to each other (they may also be further connected to each other, but this is not a limitation). Preferably, the second groove 128 extends from the portion of the upper wing plate 120C connected to the guide post 130 towards the rear end E2 and gradually narrows in the width direction W and gradually converges towards the central portion. For other parts (such as the lower wing plate 110, the guide post 130, the lower flange 140, the upper flange 150, the tab mounting post 160, and the first groove 132, etc.), reference may be made to the foregoing description, and no further elaboration will be given here. Through the above settings, when the slider 100C is mounted on the zipper tape 50 to form the zipper 20, the setting of the second groove 128 can reduce the friction between the inner edge of the zipper tape 52 and the junction between the guide post 130 and the upper wing plate 120C. Accordingly, the slider 100C and the zipper 20 can improve the smoothness of the slider 100C when sliding on the zipper tape 50, thereby reducing the damage of the zipper tape 50 and having good operability. However, the present invention does not limit the shape and whether the second groove 128 is provided, and it can be adjusted according to requirements.

[0082] In summary, in the slider of the present invention, one of the lower wing plate and the upper wing plate is provided with a pair of flanges on opposite side edges in the width direction, the inner surface of the other of the lower wing plate and the upper wing plate is opposite to the end surface of the flange with a gap therebetween, and a first groove corresponding to the gap in the up and down direction is provided on the side surface of the guide post. When the slider is installed on the zipper tape to form a zipper, the outer edge of the zipper tape passes through the gap of the slider and the inner edge of the zipper tape corresponds to the first groove provided on the side surface of the guide post of the slider. Thus, the provision of the first groove can reduce the friction between the inner edge of the zipper tape and the side surface of the guide post, and reduce the sliding resistance of the slider on the zipper tape. Preferably, a step portion is formed at the boundary between the first groove and the side surface of the guide post, and the step portion is further provided corresponding to the positions of the zipper tape and the coil chain teeth row in the zipper tape of the zipper tape used by the slider. Accordingly, the slider and the zipper of the present invention can improve the smoothness when the slider slides on the zipper tape, thereby reducing the damage of the zipper tape and having good operability.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
