TECHNICAL FIELD
[0001] The utility model relates to the technology in the field of zipper and especially relates to a slider for zipper and zipper (fastener). BACKGROUND
[0002] A common zipper generally includes a fastener chain composed of a left and right pair of fastener tapes and a left and right pair of element columns installed on the fastener tapes, and a slider installed on the fastener chain and opening or closing the element columns by sliding, so as to open or close the element columns by sliding the slider on the fastener chain. Among them, the slider is provided with a pair of element channels for the element columns to pass through, and the slider guides the element columns passing through the element channels to separate from each other (equivalent to opening the element columns) or engage with each other (equivalent to closing the element columns) by sliding.
[0003] However, in the prior art, the element channels of the slider are generally arranged corresponding to each other in the transverse direction. Therefore, in the case of closing the element columns by sliding the slider on the fastener chain, the left and right pair of element columns approach each other from the transverse direction to engage with each other (transverse engagement), so that the noise of the slider sliding on the fastener chain is large. Even if the element channels are adjusted to correspond to each other in the longitudinal direction (longitudinal engagement), the longitudinally arranged element channels may interfere with the fastener tapes. Therefore, it is necessary to improve the slider in order to reduce the noise of the slider sliding on the fastener chain and avoid the interference of the slider with the fastener tapes, thereby improving the operability.

Figure 1 to Figure 4 This invention describes the specific structure of the zipper pull 100 and the zipper 50 in the first embodiment of the present invention, and uses... Figure 5 to Figure 8 The specific structure of the zipper pull 100A and zipper 50A in the second embodiment of this utility model is described, but this is only one example and this utility model is not limited thereto. It can be adjusted according to needs.
[0045] Please refer to Figure 1 to Figure 4 In the first embodiment, the zipper 50 includes a zipper chain 60 and a zipper pull 100. The zipper chain 60 includes a pair of left and right zipper tapes 62a and 62b, and a pair of left and right zipper teeth 64a and 64b correspondingly disposed on the left and right zipper tapes 62a and 62b. The zipper pull 100 is adapted to be mounted on the left and right zipper tapes 62a and 62b of the zipper chain 60 and to engage with the left and right zipper teeth 64a and 64b of the zipper chain 60. The zipper pull 100 includes a pull body 110. The pull body 110 has a left zipper tooth channel 112a for inserting the left zipper tooth 64a of the left and right zipper teeth 64a and 64b, and a right zipper tooth channel 112b for inserting the right zipper tooth 64b of the left and right zipper teeth 64a and 64b. In the forward viewing angle of the pull body 110 (i.e., ...), Figure 2 From the perspective of [the viewpoint], the left chain tooth channel 112a and the right chain tooth channel 112b are offset along the longitudinal center line C1 extending in the longitudinal direction H on the transverse direction L of the slider body 110, and are also offset along the transverse center line C2 extending in the transverse direction L on the longitudinal direction H of the slider body 110.
[0046] Specifically, in this embodiment, as Figure 1 to Figure 4As shown, the left and right pairs of the chain rows 64a, 64b of the slide fastener chain 60 are provided on the same side surfaces of the left and right pairs of the slide fastener tapes 62a, 62b. As an example, the left and right pairs of the chain rows 64a, 64b are, for example, coil type chain elements (but not limited thereto). In correspondence thereto, the left and right chain element passages 112a, 112b of the slide fastener slider 100 are formed in the slider body 110 and extend from the front end to the rear end of the slider body 110, respectively. Among them, in the front view (i.e., the view from the front side), the left and right chain element passages 112a, 112b are arranged staggered in the lateral direction L and the longitudinal direction H. That is, in terms of the longitudinal center line Cl and the lateral center line C2 of the slider body 110 in the front view, the left and right chain element passages 112a, 112b are located in the lower left portion and the upper right portion (as shown), respectively, but can also be located in the upper left portion and the lower right portion (not shown), respectively. As an example, in the front view (i.e., the view from the front side) of the slider body 110, the left and right chain element passages 112a, 112b do not overlap each other in the lateral direction L and the longitudinal direction H (but not excluding a slight overlap in the lateral direction L or the longitudinal direction H). In this way, in the case where the slide fastener slider 100 is slid on the slide fastener chain 60 to close the left and right pairs of the chain rows 64a, 64b, as shown, with the sliding of the slide fastener slider 100, the left and right pairs of the chain rows 64a, 64b gradually approach each other from the longitudinal direction H and the lateral direction L to engage with each other through the left and right chain element passages 112a, 112b. Figure 2 Figure 2 Figure 2 Figure 2 to Figure 4
[0047]
[0048] Further, in the present embodiment, as shown, the left and right pairs of the chain rows 64a, 64b of the slide fastener chain 60 are provided on the same side surfaces of the left and right pairs of the slide fastener tapes 62a, 62b. As an example, the left and right pairs of the chain rows 64a, 64b are, for example, coil type chain elements (but not limited thereto). In correspondence thereto, the left and right chain element passages 112a, 112b of the slide fastener slider 100 are formed in the slider body 110 and extend from the front end to the rear end of the slider body 110, respectively. Among them, in the front view (i.e., the view from the front side), the left and right chain element passages 112a, 112b are arranged staggered in the lateral direction L and the longitudinal direction H. That is, in terms of the longitudinal center line Cl and the lateral center line C2 of the slider body 110 in the front view, the left and right chain element passages 112a, 112b are located in the lower left portion and the upper right portion (as shown), respectively, but can also be located in the upper left portion and the lower right portion (not shown), respectively. As an example, in the front view (i.e., the view from the front side) of the slider body 110, the left and right chain element passages 112a, 112b do not overlap each other in the lateral direction L and the longitudinal direction H (but not excluding a slight overlap in the lateral direction L or the longitudinal direction H). In this way, in the case where the slide fastener slider 100 is slid on the slide fastener chain 60 to close the left and right pairs of the chain rows 64a, 64b, as shown, with the sliding of the slide fastener slider 100, the left and right pairs of the chain rows 64a, 64b gradually approach each other from the longitudinal direction H and the lateral direction L to engage with each other through the left and right chain element passages 112a, 112b. Figure 1 to Figure 4 As shown, the puller body 110 further has a left zipper tape passage 114a for the left zipper tape 62a of the left and right pair of zipper tapes 62a, 62b to pass through, and a right zipper tape passage 114b for the right zipper tape 62b of the left and right pair of zipper tapes 62a, 62b to pass through. The left zipper tape passage 114a is connected with the left tooth passage 112a, the right zipper tape passage 114b is connected with the right tooth passage 112b, and the left zipper tape passage 114a and the right zipper tape passage 114b extend in the transverse direction L towards opposite directions. For example, the left zipper tape passage 114a extends in the transverse direction L from the left tooth passage 112a to the left side, and the right zipper tape passage 114b extends in the transverse direction L from the right tooth passage 112b to the right side. Thus, in the state that the left tooth passage 112a and the right tooth passage 112b allow the left and right pair of tooth rows 64a, 64b to pass through, the left zipper tape passage 114a and the right zipper tape passage 114b allow the left and right pair of zipper tapes 62a, 62b to pass through. In addition, the left zipper tape passage 114a and the right zipper tape passage 114b each have a dimension in the longitudinal direction H smaller than that of the left tooth passage 112a and the right tooth passage 112b respectively.
[0049] Further, in the present embodiment, as shown in Figure 1 to Figure 4 the puller body 110 further has a left flange 116a disposed at the left side of the transverse direction L of the left tooth passage 112a, and a right flange 116b disposed at the right side of the transverse direction L of the right tooth passage 112b. The left flange 116a is protrusively disposed at the left side of the transverse direction L of the left tooth passage 112a to form the left zipper tape passage 114a, and the right flange 116b is protrusively disposed at the right side of the transverse direction L of the right tooth passage 112b to form the right zipper tape passage 114b. Thus, by the provision of the left flange 116a and the right flange 116b, the zipper puller 100 can restrict the position of the left and right pair of tooth rows 64a, 64b passing through the left tooth passage 112a and the right tooth passage 112b in the transverse direction L, and easily form the left zipper tape passage 114a and the right zipper tape passage 114b for the left and right pair of zipper tapes 62a, 62b to pass through.
[0050] Further, in the present embodiment, as shown in Figure 1 to Figure 4 the left tooth passage 112a and the right tooth passage 112b are staggered in the transverse direction L and the longitudinal direction H at the left passage front side port 118a of the front end of the puller body 110 and the right passage front side port 118b of the front end of the puller body 110 respectively (as shown in Figure 2As shown), the left chain tooth channel 112a at the rear end of the slider body 110 has a left channel rear opening 119a, and the right chain tooth channel 112b at the rear end of the slider body 110 has a right channel rear opening 119b, which are connected to each other in the horizontal direction L (as shown). Figure 4 As shown). As an example, the left chain tooth channel 112a located in the lower left part in the forward view (as shown). Figure 2 As shown) it extends gradually from the lower left part upwards to the middle of the vertical H and from the left side to the middle of the horizontal L (as shown). Figure 4 As shown), and in the forward-looking view, the right chain tooth channel 112b is located in the upper right part (as shown). Figure 2 As shown) it extends gradually from the upper right part downwards to the middle of the vertical H and from the right side towards the middle of the horizontal L (as shown). Figure 4 (As shown). Thus, the front opening 118a of the left channel and the front opening 118b of the right channel are staggered in the horizontal direction L and the vertical direction H (as shown). Figure 2 As shown in Figure 4, the zipper strips 62a and 62b connected to the zipper pull 100, which are separated from each other by the front ends of the left zipper tooth channel 112a and the right zipper tooth channel 112b, can avoid interference with each other. Furthermore, the rear openings 119a and 119b of the left and right channels are connected in the middle part of the longitudinal direction H (as shown in Figure 4), which makes it easier for the zipper tooth rows 64a and 64b that are separated from the rear ends of the left zipper tooth channel 112a and the right zipper tooth channel 112b to mesh with each other.
[0051] Additionally, in this embodiment, as Figure 1 to Figure 4 As shown, the left zipper channel 114a is located at one end of one of the upper and lower sides of the left zipper tooth channel 112a (e.g., Figure 2 The lower end shown), and the right zipper channel 114b is located at one end of the upper and lower sides of the right zipper tooth channel 112b (e.g., the ...). Figure 2 (See the lower end shown). That is, the shape of the space formed by the left zipper tooth channel 112a and the left zipper tape channel 114a is opposite to the shape of the space formed by the right zipper tooth channel 112b and the right zipper tape channel 114b in the horizontal direction L (the left zipper tape channel 114a and the right zipper tape channel 114b extend in opposite directions), but are the same in the vertical direction H (the left zipper tape channel 114a is below the left zipper tooth channel 112a and the right zipper tape channel 114b is below the right zipper tooth channel 112b). Thus, the zipper pull 100 with zipper tape channels provided on the same side is suitable for zipper chains 60 facing the same side of the front of the zipper tapes 62a and 62b (for example, the side with the zipper tooth rows 64a and 64b, or the side without the zipper tooth rows 64a and 64b). However, this utility model is not limited to this and can be adjusted according to needs.
[0052] Therefore, please refer to Figure 5 to Figure 8 In the second embodiment, the zipper pull 100A is adapted to be installed on the left and right pairs of zipper tapes 62a, 62b of the zipper chain 60A and engage with the left and right pairs of chain teeth 64a, 64b of the zipper chain 60A. The zipper chain 60A includes the left and right pairs of zipper tapes 62a, 62b and corresponding left and right pairs of chain teeth 64a, 64b disposed on the left and right pairs of zipper tapes 62a, 62b. The main difference between this and the aforementioned zipper chain 60 is that one of the left and right pairs of zipper tapes 62a, 62b of the zipper chain 60A is reversed, so that the left and right pairs of chain teeth 64a, 64b face opposite directions. For example, the left chain teeth 64a connected to the left zipper tape 62a face upwards, and the right chain teeth 64b connected to the right zipper tape 62b face downwards. Thus, the main difference between the zipper pull 100A applied to the aforementioned zipper chain 60A and the aforementioned zipper pull 100 is that the positions of the left zipper tape channel 114a and the right zipper tape channel 114b in the pull body 110A, through which the left and right zipper tapes 62a and 62b pass, are also adjusted to correspond to the reversed zipper chain 60A.
[0053] In detail, in this embodiment, such as Figure 5 to Figure 8 The left zipper tape channel 114a in the zipper head body 110A is located at one end of the upper or lower side of the left zipper tooth channel 112a (e.g., Figure 6 (as shown at the lower end), and the right zipper tape channel 114b in the zipper head body 110A is located at the end of the other side of the upper and lower sides of the right zipper tooth channel 112b (e.g. Figure 6 (As shown at the upper end). That is, the shape of the space formed by the left zipper tooth channel 112a and the left zipper tape channel 114a is opposite to the shape of the space formed by the right zipper tooth channel 112b and the right zipper tape channel 114b in the horizontal direction L (the left zipper tape channel 114a and the right zipper tape channel 114b extend in opposite directions) and in the vertical direction H (the left zipper tape channel 114a is below the left zipper tooth channel 112a and the right zipper tape channel 114b is above the right zipper tooth channel 112b). Thus, the zipper pull 100A with zipper tape channels on different sides is suitable for the zipper chain 60A with the front side of the zipper tapes 62a and 62b (for example, the side with the zipper tooth rows 64a and 64b, or the side without the zipper tooth rows 64a and 64b) facing the opposite side (reversed). However, this utility model is not limited to this and can be adjusted according to needs.
[0054] In conclusion, in the zipper puller and the zipper, the puller body of the zipper puller has the left side zipper tooth channel and the right side zipper tooth channel, and under the front view angle of the puller body, the left side zipper tooth channel and the right side zipper tooth channel are staggered in the horizontal direction along the longitudinal center line and are staggered in the longitudinal direction along the horizontal center line. In this way, when the zipper puller slides on the zipper chain to close the zipper tooth row, the zipper tooth row is close to each other in the longitudinal direction and the horizontal direction and is engaged with each other, so that the noise of the zipper puller sliding on the zipper chain can be reduced. Moreover, the left side zipper tooth channel and the right side zipper tooth channel are staggered in the longitudinal direction without overlapping, so that the interference of the zipper puller to the zipper tape can be avoided. Preferably, the puller body also has the left side zipper tape channel and the right side zipper tape channel arranged on the same side or different sides of the upper and lower sides, so that the zipper puller is suitable for the zipper chain with the front of the zipper tape facing the same side or the opposite side (reversed) and has wide application. Accordingly, the zipper puller and the zipper can improve the operability.
[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
