Description

[Technical Field]

[0001] The present invention relates to the technical field of zippers, and more particularly to a zipper puller that is a detachable puller auxiliary device, and a zipper slider to which the zipper puller is attached. [Background technology]

[0002] Nowadays, zippers are widely used in everyday items such as clothing, bags, tents, and bedding, and zippers are used to assemble and separate items.

[0003]

[0003] A zipper typically includes a pair of fabric tapes, a zipper stringer fixed to the inner edge of each fabric tape, and a slider. The slider includes a slider body attached to the zipper stringer and a pull tab attached to the surface of the slider body. By holding the pull tab and pulling the slider body along the length of the zipper, the pair of zipper stringers are engaged or separated, thereby closing or opening the zipper. In order to improve the design of the zipper, some prior art zippers are equipped with a pull tab auxiliary device that is detachably attached to the pull tab of the zipper slider. The pull tab auxiliary device not only improves the convenience of pulling the slider, but also enhances the design of the zipper.

[0004] In the prior art fastener puller disclosed in Patent Document 1, when attaching the auxiliary puller, the auxiliary puller portion of the auxiliary puller is passed through the attachment hole of the puller body, and then the neck portion of the end of the auxiliary puller portion is held in the attachment hole of the puller body by restricting the position of the head. This makes it easy to attach the auxiliary puller, but because the auxiliary puller portion must be passed through the attachment hole when attaching, and the other end of the auxiliary puller portion away from the neck portion is the grip portion, the shape of the grip portion is restricted by the attachment hole of the puller body, making it difficult to design a more flexible outer shape of the grip portion, which in turn restricts the outer shape of the auxiliary puller.

[0005] To address the above-mentioned problems, a zipper puller with a rotatable and detachable puller auxiliary is provided, in which an attachment hole is formed in a metal puller body, an auxiliary post and an elastically deformable auxiliary head are provided at one end of the puller auxiliary, and both the attachment hole and the auxiliary head are rectangular and extend along the width direction of the zipper puller, and the auxiliary post is rotatably received in the attachment hole. To attach the puller auxiliary, the puller auxiliary is first positioned horizontally so that it coincides with the width direction of the zipper puller, and the length of the auxiliary head coincides with the length of the attachment hole. By pressing the auxiliary head, the auxiliary head can be passed through the attachment hole and the auxiliary post can be received in the attachment hole. Next, the puller auxiliary is rotated downward 90° so that it coincides with the length of the zipper puller, and the length of the auxiliary head is perpendicular to the length of the attachment hole, i.e., the auxiliary head and the attachment hole intersect to form a cross, and a portion of the auxiliary head abuts against the surface of the puller body, preventing the auxiliary head from being removed in the reverse direction from the attachment hole. The removal process of the pull aid is the reverse of the installation process. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Chinese Patent No. 110811084 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the above-mentioned zipper pullers with rotatable and detachable puller auxiliary devices still have the following drawbacks: 1. When the puller auxiliary device is attached and in a vertical position, there is a large gap between the auxiliary device post and the mounting hole wall in the width direction of the zipper puller, resulting in insufficient tightness between the puller auxiliary device and the puller body, making the puller auxiliary device prone to rattle in this direction and making it difficult to maintain a stable position after attachment; 2. To prevent rattle after attachment, some zipper pullers have a protrusion on the back of the puller body, which abuts against the outer periphery of the puller auxiliary device in a vertical position to limit rattle, but the protrusion detracts from the aesthetic appearance of the puller body.

[0008] In view of the drawbacks of the prior art, the technical problem that the present invention aims to solve is to provide a detachable zipper puller auxiliary that can ensure secure fastening between the puller auxiliary and the puller body after the puller auxiliary is attached and can improve the aesthetic appearance of the puller body. [Means for solving the problem]

[0009] In order to achieve the above object, the detachable zipper puller of the present invention includes a puller body and a puller auxiliary, The pull tab body is provided with a penetrating mounting hole, an auxiliary tool mounting portion distributed around the outer periphery of the mounting hole, and a limiting groove penetrating the auxiliary tool mounting portion, the limiting groove being distributed on the hole wall of the mounting hole and communicating with the mounting hole, and the mounting hole having different hole diameters in at least two intersecting directions, The puller auxiliary tool includes an auxiliary tool main body, an auxiliary tool post portion extending from the auxiliary tool main body, an auxiliary tool head provided at the outer end of the auxiliary tool post portion along the extension direction of the auxiliary tool post portion, and a limiting protrusion protruding from the outer periphery of the auxiliary tool post portion, the limiting protrusion being distributed between the auxiliary tool main body and the auxiliary tool head, the auxiliary tool head having different lengths in at least two intersecting directions, and the auxiliary tool post portion being rotatably accommodated in the mounting hole, The pull-tab auxiliary tool has an insertion / removal position and a holding position with respect to the pull-tab main body, When the pull-tab auxiliary tool is in the insertion / removal position, the length direction of the auxiliary tool head coincides with the length direction of the mounting hole, and the auxiliary tool head can be passed through the mounting hole; When the pull aid is in the holding position, the longitudinal direction of the aid head intersects with the longitudinal direction of the mounting hole, the aid body and the aid head abut on both sides of the aid mounting portion, respectively, the limiting protrusion is accommodated in the limiting groove, and the outer surface of the limiting protrusion abuts and engages with the groove wall surface of the limiting groove.

[0010] First, in this application, the pull-tab auxiliary tool can be rotated and detached from the pull-tab main body, and neither the mounting hole nor the auxiliary tool head has a perfect circular structure, but the mounting hole has a larger diameter in its longitudinal direction, and the auxiliary tool head has a larger length in its longitudinal direction. In this way, when attaching the pull-tab auxiliary tool, first, the pull-tab auxiliary tool is positioned in the insertion / removal position, i.e., the longitudinal direction of the auxiliary tool head is aligned with the longitudinal direction of the mounting hole, and then, by pressing the auxiliary tool head, the auxiliary tool head can be simply and easily inserted into the mounting hole and passed through the mounting hole. Next, the pull-tab auxiliary tool is rotated to its holding position, i.e., the longitudinal direction of the auxiliary tool head intersects with the longitudinal direction of the mounting hole, and at this time, the auxiliary tool main body and the auxiliary tool head abut on both sides of the auxiliary tool mounting part along the thickness direction of the auxiliary tool mounting part, thereby connecting the pull-tab auxiliary tool to the pull-tab main body. To remove the pull-tab auxiliary, first rotate the pull-tab auxiliary from the retaining position to the insertion / removal position, and then bias the auxiliary head to pull it out of the mounting hole, thereby detaching the pull-tab auxiliary from the pull-tab main body. Therefore, in this application, the pull-tab auxiliary can be rotated and detached from the pull-tab main body, and the operation of pressing the auxiliary head into the mounting hole is very simple, making it not only easy to install and replace the pull-tab auxiliary, but also because the mounting hole does not impose any restrictions on the auxiliary body, and therefore does not limit the external design of the pull-tab auxiliary, allowing pull-tab auxiliary with any external shape to be used in this application, greatly improving and enriching the design of zipper pulls and ultimately improving and enriching the design of zippers.

[0011] Next, after the pull-tab auxiliary is installed, it is always in its retaining position, and in this state, the limiting protrusion on the pull-tab auxiliary engages with the limiting groove, and the outer circumferential surface of the limiting protrusion abuts against the groove wall surface of the limiting groove, thereby improving the tightness between the pull-tab auxiliary and the pull-tab main body, and even if there is a large gap between the auxiliary post part and the hole wall of the mounting hole, rattle of the pull-tab auxiliary is reliably limited, and the state of the pull-tab auxiliary after installation can be stably maintained. Also, because the structure on the pull-tab main body that limits rattle of the pull-tab auxiliary is a limiting groove rather than a protrusion structure, there are no noticeable protruding parts on the appearance of the pull-tab main body, making the appearance of the pull-tab main body more aesthetically pleasing.

[0012] Furthermore, the mounting hole on the pull handle body is preferably provided with the following structure: the mounting hole is an oval or rectangular hole, the length of which coincides with the width of the pull handle body, the width of which coincides with the length of the pull handle body, and the hole wall of the mounting hole has a pair of lateral hole walls disposed opposite each other along the length of the pull handle body, and the limiting groove is located at a midpoint between the lateral hole walls, so that when the pull handle auxiliary tool is in the insertion / removal position, the length of the auxiliary tool head coincides with the width of the pull handle body, and when the pull handle auxiliary tool is in the retaining position, the length of the auxiliary tool head coincides with the length of the pull handle body. After providing the mounting hole in this manner, the hole wall of the mounting hole has a pair of lateral hole walls disposed opposite each other along the length of the pull handle body, and the limiting groove is located at a midpoint between the lateral hole walls, so that when the pull handle auxiliary tool is in the retaining position, the length of the auxiliary tool head coincides with the length of the pull handle body.

[0013] Furthermore, the length of the auxiliary tool body coincides with the length of the auxiliary tool head, and both ends of the auxiliary tool head are provided with vertical protrusions extending outward from the auxiliary tool post along the length of the auxiliary tool head, and the restricting protrusions are distributed between the auxiliary tool body and the vertical protrusions, and when the pull tab auxiliary is in the holding position, the vertical protrusions abut against the surface of the auxiliary tool attachment part, thereby preventing the pull tab auxiliary from coming out of the attachment hole of the pull tab main body. Furthermore, after the pull tab auxiliary is attached, the auxiliary tool body of the pull tab auxiliary extends along the length of the pull tab main body, resulting in a highly consistent overall shape of the zipper pull tab, which helps improve the overall appearance of the zipper pull tab and ultimately improves the aesthetics of the zipper pull tab's external shape.

[0014] Furthermore, when the pull-tab auxiliary is attached, the inserting direction of the auxiliary head into the mounting hole is from the front to the back of the pull-tab body, and a receiving groove is formed on the back of the auxiliary attachment part of the pull-tab body along the length of the pull-tab body on both sides of the mounting hole, communicating with the mounting hole, and when the pull-tab auxiliary is in the holding position, the vertical protrusion is located in the receiving groove. In this way, the free rotation and removal of the auxiliary head is restricted, and thus the free rotation and removal of the pull-tab auxiliary is restricted, thereby improving the attachment reliability of the pull-tab auxiliary. Furthermore, because the receiving groove is a groove structure on the back of the pull-tab body, it does not affect the front appearance of the pull-tab body, avoiding the creation of noticeable protrusions on the appearance of the pull-tab body, and ensuring the appearance of the pull-tab body.

[0015] Furthermore, the groove wall of the limiting groove has a first inclined wall surface and a second inclined wall surface that are symmetrically arranged along the width direction of the pull tab body, and the outer peripheral surface of the limiting protrusion has a first inclined wall surface and a second inclined wall surface that are symmetrically arranged, and when the pull tab auxiliary is in the holding position, the first inclined wall surface and the first inclined wall surface, and the second inclined wall surface and the second inclined wall surface, are both in surface contact and engage with each other, thereby improving the degree of fastening between the pull tab auxiliary and the pull tab body after installation and more reliably restricting rattle of the pull tab auxiliary.

[0016] Preferably, the limiting groove is a triangular groove, and the limiting protrusion is a triangular protrusion that fits into the limiting groove.

[0017] Furthermore, the horizontal hole wall has a first inclined segment and a second inclined segment arranged symmetrically along the width direction of the pull tab body, the first inclined segment and the second inclined segment respectively connected to both ends of the limiting groove, and both extend at an angle that moves away from the horizontal centerline of the mounting hole the further away from the limiting groove, and when the pull tab auxiliary is in the retaining position, the connection point between the first inclined segment and the limiting groove and the connection point between the second inclined segment and the limiting groove both abut against the outer peripheral surface of the auxiliary tool post. Thus, the presence of the inclined segments on the hole wall of the mounting hole further improves the tightness between the pull tab auxiliary and the pull tab body after installation, strengthening the multi-directional tensile force of the pull tab auxiliary and preventing the pull tab auxiliary from accidentally coming off the mounting hole during use.

[0018] Furthermore, the assisting tool body includes a pull tab connecting segment, an inclined extending segment, and a thick-walled gripping segment connected in this order along its length, the assisting tool post being located at the end of the pull tab connecting segment farther from the thick-walled gripping segment and extending along the thickness direction of the assisting tool body, the inclined extending segment extending at an angle such that it is farther from the pull tab body as it approaches the thick-walled gripping segment, thereby separating the thick-walled gripping segment from the surface of the fastener, allowing the user to grip it better, and the relatively increased thickness of the thick-walled gripping segment providing the user with a better gripping sensation.

[0019] Furthermore, the outer contour size of the auxiliary tool head is larger than the contour size of the mounting hole, and in the puller auxiliary tool, at least the auxiliary tool head is an elastically deformable body, which not only makes it easy to pass the auxiliary tool head through the mounting hole, but also prevents the auxiliary tool head from coming off in the opposite direction after passing through the mounting hole.

[0020] Furthermore, the pull tab body is a one-piece molded part made of zinc alloy, and the pull tab auxiliary is a one-piece molded part made of TPU. Because the pull tab body is a one-piece molded part made of zinc alloy, it has high structural strength and excellent durability. Furthermore, because the pull tab auxiliary is a one-piece molded part made of TPU, it is easy to manufacture at low cost, making it easy to design multiple pull tab auxiliary devices with different shapes and colors at low cost. Combined with the removable structure of the pull tab auxiliary on the pull tab body, it is easy for users to replace different pull tab auxiliary devices, enriching the design possibilities of the zipper.

[0021] The zipper slider of the present invention includes a slider body and a zipper pull tab of the aforementioned detachable pull tab auxiliary device, and the pull tab body is connected to the slider body.

[0022] As described above, the zipper pull tab and zipper slider of the detachable pull tab assistant according to the present invention have the following beneficial effects.

[0023] 1. In this application, the puller auxiliary tool can be rotated and detached from the puller body, and the operation of pressing the auxiliary tool head into the mounting hole is very simple, which not only makes it easy to install and replace the puller auxiliary tool, but also does not impose any restrictions on the auxiliary tool body due to the mounting hole, thereby not restricting the external design of the puller auxiliary tool. As a result, puller auxiliary tools of any external shape can be used in this application, which greatly improves and enriches the design of zipper pulls and ultimately improves and enriches the design of zippers.

[0024] 2. After the pull-tab auxiliary is installed, it is always in its retaining position, and in this state, the limiting protrusion on the pull-tab auxiliary engages with the limiting groove, and the outer surface of the limiting protrusion abuts against the wall of the limiting groove, thereby improving the tightness between the pull-tab auxiliary and the pull-tab main body, and even if there is a large gap between the auxiliary post and the wall of the mounting hole, it is possible to reliably limit the rattle of the pull-tab auxiliary and stably maintain the state of the pull-tab auxiliary after installation.In addition, because the structure on the pull-tab main body that limits the rattle of the pull-tab auxiliary is a limiting groove rather than a protrusion structure, there are no noticeable protrusions on the appearance of the pull-tab main body, making the appearance of the pull-tab main body more aesthetically pleasing.

When an element is described as being "connected" to another element, it may be directly connected to the other element, or it may be indirectly connected to the other element via intermediate elements.

[0029] Furthermore, references to "first," "second," etc. in this application are for illustrative purposes only and should not be understood as indicating or implying the relative importance of the features or the number of the designated technical features. Accordingly, a feature qualified as "first" or "second" may explicitly or implicitly include at least one of the features. Furthermore, to the extent feasible by a person skilled in the art, the technical means of each embodiment may be combined. If a combination of technical means is inconsistent or infeasible, such combination of technical means should be deemed not to exist and not to fall within the scope of protection of this application.

[0030] This application relates to the technical field of fasteners. For convenience of explanation, in the following examples, the length direction of the fastener is defined as the front-to-rear direction, the width direction of the fastener as the left-to-right direction, and the thickness direction of the fastener as the up-to-down direction. The fastener includes a pair of cloth tapes distributed mainly side by side laterally, zipper stringers fixed to the inner edges of each cloth tape and extending front to back, and a zipper slider, which is attached to the zipper stringers so as to be slidable back and forth. When the zipper slider is moved forward, the pair of zipper stringers engage with each other to close the zipper, and when the zipper slider is moved backward, the pair of zipper stringers separate to open the zipper.

[0031] As shown in Figures 1 to 3, the present invention mainly relates to a zipper slider and a zipper pull tab used with the zipper slider, and the zipper pull tab is a zipper pull tab of a detachable pull tab auxiliary device 20. The length, width, and thickness directions of the zipper slider correspond one-to-one to the length, width, and thickness directions of the zipper, and the length, width, and thickness directions of the zipper pull tab also correspond one-to-one to the length, width, and thickness directions of the zipper. Based on this, in the drawings shown in Figures 1, 4, and 7, the top of the paper is the front direction, the bottom of the paper is the back direction, the left side of the paper is the left direction, the right side of the paper is the right direction, the front of the paper is the up direction, and the back of the paper is the down direction.

[0032] The fastener slider according to the present invention includes a slider body 30 and a fastener pull tab of a detachable pull tab auxiliary device 20. As shown in FIGS. 1 to 3, the slider body 30 includes upper and lower wing plates 31 and 32 arranged opposite to each other at the top and bottom, an element passage formed between the upper and lower wing plates 31 and 32, and a pull tab attachment post 33 fixed to the upper surface of the upper wing plate 31, and a part of an element of a fastener stringer is accommodated in the element passage. The fastener pull tab includes a pull tab body 10 and a pull tab auxiliary device 20, and the front end of the pull tab body 10 is connected to the pull tab attachment post 33 of the slider body 30, so that the entire fastener pull tab is attached to the upper surface of the slider body 30. The rear end of the pull tab body 10 is removably connected to the pull tab auxiliary device 20, so that the pull tab auxiliary device 20 is replaceable.

[0033] 4 to 6, the front portion of the pull tab body 10 is a slider attachment portion 15 that is connected to the pull tab attachment post 33 of the slider body 30. Preferably, the slider attachment portion 15 of the pull tab body 10 is provided with a post connection hole 151 that passes through the pull tab body 10 from top to bottom along the thickness direction of the pull tab body 10, and the slider attachment portion 15 of the pull tab body 10 is attached to the pull tab attachment post 33 of the slider body 30 via the post connection hole 151, thereby attaching the pull tab body 10 to the slider body 30.

[0034] 4 and 6, the rear of the pull handle body 10 is an auxiliary tool attachment section 12 that is connected to the pull handle auxiliary tool 20. The auxiliary tool attachment section 12 of the pull handle body 10 is formed with an attachment hole 11 and a limiting groove 13 that both pass through the attachment hole 11. The auxiliary tool attachment sections 12 are distributed around the outer periphery of the attachment hole 11. The attachment hole 11 is not a perfect circle but is, for example, an ellipse, rectangle, oval, or trapezoid, and has different hole diameters in at least two intersecting directions and a larger hole diameter in the longitudinal direction. The limiting grooves 13 are distributed on the hole wall of the attachment hole 11 and communicate with the attachment hole 11. As shown in Figures 7 to 10, the pull handle auxiliary device 20 includes an auxiliary device main body 21 extending forward and backward, an auxiliary device post 22 extending downward from the front end of the auxiliary device main body 21, an auxiliary device head 23 fixed to the lower end of the auxiliary device post 22 along the extension direction of the auxiliary device post 22, and a limiting protrusion 24 protruding from the outer periphery of the auxiliary device post 22, the auxiliary device post 22 having a cylindrical or rectangular structure and being rotatably received in the mounting hole 11, the auxiliary device head 23 being fixed to the outer end of the auxiliary device post 22 and not being a perfect circle but having, for example, an ellipse, rectangle, oval, trapezoid, etc., and having different lengths in at least two intersecting directions and having a greater length in the length direction, and the limiting protrusion 24 being distributed between the auxiliary device main body 21 and the auxiliary device head 23 in the vertical direction.

[0035] Furthermore, the pull tab auxiliary 20 has an insertion / removal position and a retaining position relative to the pull tab main body 10. The insertion / removal position and the retaining position of the pull tab auxiliary 20 are two different positions, and the pull tab auxiliary 20 can be placed in the insertion / removal position or the retaining position by rotating the pull tab auxiliary 20. When the pull tab auxiliary 20 is in the insertion / removal position, as shown in FIG. 11, the length direction of the auxiliary tool head 23 coincides with the length direction of the mounting hole 11, allowing the auxiliary tool head 23 to be passed through the mounting hole 11. When the pull tab auxiliary 20 is in the retaining position, as shown in FIG. 12, the length direction of the auxiliary tool head 23 intersects with the length direction of the mounting hole 11, and the auxiliary tool main body 21 and the auxiliary tool head 23 abut on both sides of the auxiliary tool mounting part 12, the auxiliary tool post part 22 is received in the mounting hole 11, and the limiting protrusion 24 is received in the limiting groove 13, with its outer circumferential surface abutting and engaging with the groove wall surface of the limiting groove 13.

[0036] The pull tab main body 10 and the pull tab auxiliary device 20 configured as described above allow the pull tab auxiliary device 20 to be rotated and detached from the pull tab main body 10, and the pull tab main body 10 and the pull tab auxiliary device 20 can be separated or combined.

[0037] When attaching the pull tab auxiliary tool 20, as shown in FIG. 13, first, the pull tab auxiliary tool 20 is set to the insertion / removal position, that is, the length direction of the auxiliary tool head 23 is aligned with the length direction of the mounting hole 11, and after aligning the auxiliary tool head 23 with the mounting hole 11, the auxiliary tool head 23 is biased and pressed. At this time, the maximum length direction of the auxiliary tool head 23 and the maximum hole diameter direction of the mounting hole 11 are aligned, so by biasing and pressing the auxiliary tool head 23, the auxiliary tool head 23 can be easily pushed into the mounting hole 11 and can be easily passed through the mounting hole 11. Next, the auxiliary tool head 23 holds the pull tab auxiliary tool 20 that has been passed through the mounting hole 11. 2 and 3, because neither the mounting hole 11 nor the auxiliary tool head 23 is a perfect circle, the size of the auxiliary tool head 23 in the longitudinal direction is larger than the diameter of the mounting hole 11 in that direction, and the part of the auxiliary tool head 23 that protrudes from the auxiliary tool post 22 abuts against the auxiliary tool mounting part 12; in other words, the auxiliary tool main body 21 and the auxiliary tool head 23 abut against the upper and lower sides of the auxiliary tool mounting part 12 along the thickness direction of the auxiliary tool mounting part 12, respectively, preventing the auxiliary tool head 23 from coming off the mounting hole 11, and connecting the pull handle auxiliary tool 20 to the pull handle main body 10.

[0038] When removing the pull tab auxiliary device 20, as shown in Figure 14, first rotate the pull tab auxiliary device 20 from the holding position to the insertion / removal position, that is, align the length direction of the auxiliary device head 23 with the length direction of the mounting hole 11, and then force the auxiliary device head 23 to pull it out of the mounting hole 11.At this time, the maximum length direction of the auxiliary device head 23 will be aligned with the maximum hole diameter direction of the mounting hole 11, so by forcefully pulling out the pull tab auxiliary device 20, the auxiliary device head 23 can be easily pulled out of the mounting hole 11, and the pull tab auxiliary device 20 can be removed from the pull tab main body 10.

[0039] Therefore, the present application realizes rotational attachment and detachment of the puller auxiliary device 20 to the puller body 10, allowing for replacement of different puller auxiliary devices 20. The operation of pushing the auxiliary device head 23 into and pulling it out of the mounting hole 11 is very simple, making installation and removal of the puller auxiliary device 20 easy. In this way, not only is installation and replacement of the puller auxiliary device 20 easy, but the auxiliary device body 21 does not need to be passed through the mounting hole 11 during the installation and removal process, avoiding any restrictions on the auxiliary device body 21 caused by the mounting hole 11 and thus eliminating restrictions on the external design of the puller auxiliary device 20. As a result, the present application allows the use of puller auxiliary devices 20 of any external shape, greatly improving and enriching the design of zipper pullers and ultimately improving and enriching the design of zippers. In particular, after the installation of the pull-tab auxiliary 20 is complete, the pull-tab auxiliary 20 is always in its retaining position, and in this state, the limiting protrusion 24 of the pull-tab auxiliary 20 engages with the limiting groove 13, and the outer circumferential surface of the limiting protrusion 24 abuts against the groove wall surface of the limiting groove 13, thereby improving the tightness between the pull-tab auxiliary 20 and the pull-tab main body 10, and reliably limiting rattle of the pull-tab auxiliary 20 even if there is a large gap between the auxiliary post 22 and the hole wall of the mounting hole 11, thereby enabling the pull-tab auxiliary 20 to be stably maintained in its installed state. Furthermore, because the structure that limits rattle of the pull-tab auxiliary 20 on the pull-tab main body 10 is the limiting groove 13 rather than a protrusion structure, there are no noticeable protruding parts on the appearance of the pull-tab main body 10, making the appearance of the pull-tab main body 10 more aesthetically pleasing.

[0040] Furthermore, the mounting holes 11 on the pull handle body 10 may be installed in various ways, as follows: The length of the mounting holes 11 may coincide with the length of the pull handle body 10, the width of the pull handle body 10, or intersect with both the length and width of the pull handle body 10. In this embodiment, the mounting holes 11 on the pull handle body 10 are preferably installed as follows: As shown in Figures 4 and 5, the mounting holes 11 are rectangular holes, and the length of the mounting holes 11 and the width of the pull handle body 10 coincide with each other and are both left-right directions. That is, the mounting holes 11 extend left and right along the width of the pull handle body 10, and the width of the mounting holes 11 and the length of the pull handle body 10 coincide with each other and are both front-to-back directions. The mounting holes 11 penetrate the pull handle body 10 from top to bottom along the thickness of the pull handle body 10. The mounting hole 11 with a rectangular hole structure has a substantially rectangular hole wall contour, and the hole walls of the mounting hole 11 include a pair of horizontal hole walls 111 and a pair of vertical hole walls 114. The pair of horizontal hole walls 111 are distributed facing each other in the front-to-back direction along the length of the pull tab body 10 and extend substantially left-to-right. The pair of vertical hole walls 114 are distributed facing each other in the left-to-right direction along the width of the pull tab body 10 and extend front-to-back. Adjacent horizontal hole walls 111 and vertical hole walls 114 are connected by arc segments 115. That is, all four corners of the mounting hole 11 with a rectangular hole structure are arc segments 115. Therefore, the diameter of the mounting hole 11 is largest between the pair of vertical hole walls 114 (i.e., in the left-to-right direction) and smallest between the pair of horizontal hole walls 111 (i.e., in the front-to-back direction). Naturally, in other embodiments, the mounting hole 11 may be an oval hole.

[0041] Furthermore, the length direction of the auxiliary tool body 21 coincides with the length direction of the auxiliary tool head 23. When the pull handle auxiliary tool 20 is in the insertion / removal position, as shown in Fig. 11, the length direction of the auxiliary tool head 23, the length direction of the auxiliary tool body 21, and the width direction of the pull handle body 10 coincide, all of which are in the left-right direction, and the insertion / removal position of the pull handle auxiliary tool 20 is a horizontal position in the left-right direction. When the pull handle auxiliary tool 20 is in the holding position, as shown in Fig. 12, the length direction of the auxiliary tool head 23, the length direction of the auxiliary tool body 21, and the length direction of the pull handle body 10 coincide, all of which are in the front-to-back direction, and the holding position of the pull handle auxiliary tool 20 is a vertical position in the front-to-back direction. 11, when attaching the pull tab auxiliary 20, first, place the pull tab auxiliary 20 in a horizontal position and align the length of the auxiliary head 23 with the length of the mounting hole 11. Next, press the auxiliary head 23 downward to pass it through the mounting hole 11, and then rotate the pull tab auxiliary 20 backward by 90° to complete the attachment, at which point the auxiliary head 23 and the mounting hole 11 are perpendicular and intersect in a cross shape. After the attachment of the pull tab auxiliary 20 is complete, the auxiliary body 21 of the pull tab auxiliary 20 extends along the length of the pull tab body 10 and is aligned with the length of the zipper, resulting in a very high degree of conformity between the overall outlines of the zipper pull tab and the zipper, which helps to improve the overall appearance of the zipper pull tab and the appearance of the zipper pull tab and zipper.

[0042] Furthermore, whether the pull tab auxiliary device 20 is in the insertion / removal position or the holding position, after the auxiliary device head 23 is passed through the mounting hole 11, the auxiliary device post portion 22 can be accommodated in the mounting hole 11, and at this time, based on the rectangular or oval shape of the mounting hole 11, there is a gap between the outer surface of the auxiliary device post portion 22 and a pair of vertical hole walls 114 of the mounting hole 11, which allows the pull tab auxiliary device 20 to be easily rotated later, and thus also makes it easy to attach and remove the pull tab auxiliary device 20.

[0043] 8 to 10, when the pull handle auxiliary 20 is in the holding position (i.e., vertical position), vertical protrusions 231 extending outward from the auxiliary tool post 22 are provided at both the front and rear ends of the auxiliary tool head 23 along the length of the head, and the limiting protrusions 24 are distributed between the auxiliary tool main body 21 and the vertical protrusions 231. Horizontal protrusions 232 extending outward from the auxiliary tool post 22 are provided at both the left and right ends of the head 23 along the width of the head, and the extension length of the vertical protrusions 231 in the front-to-rear direction is greater than the extension length of the horizontal protrusions 232 in the left-to-right direction. When the pull handle auxiliary 20 is in the holding position, the vertical protrusions 231 abut against the lower surface (surface) of the auxiliary tool attachment portion 12, restricting the pull handle auxiliary 20 from coming off upward from the pull handle main body 10.

[0044] Preferably, the extension length of the vertical protrusion 231 in the front-to-rear direction should be such that when the pull aid 20 is in the horizontal position shown in FIG. 11 and the aid head 23 is aligned with the mounting hole 11, the aid head 23 can be easily passed through the mounting hole 11 by pressing the aid head 23 downward, and after the aid head 23 is passed downward through the mounting hole 11 and the pull aid 20 is rotated backward by 90°, most of the vertical protrusion 231 abuts against the underside of the aid mounting part 12, thereby reliably preventing the aid head 23 from coming off the mounting hole 11.

[0045] 4 and 5, the limiting grooves 13 are provided at the middle positions of the horizontal hole walls 111, are distributed along the longitudinal centerline of the pull handle body 10, and penetrate the auxiliary tool attachment part 12 from top to bottom along the thickness direction of the auxiliary tool attachment part 12. When the pull handle auxiliary tool 20 is in the holding position, the limiting grooves 13 and the limiting protrusions 24 abut and engage with each other, thereby better restricting the pull handle auxiliary tool 20 from wobbling in the width direction of the pull handle body 10, preventing the pull handle auxiliary tool 20 from deflecting to the right or left, and maintaining the pull handle auxiliary tool 20 in a vertical state. Furthermore, of the pair of horizontal hole walls 111 of the attachment hole 11, the limiting groove 13 may be provided only on the front horizontal hole wall 111, or only on the rear horizontal hole wall 111, and correspondingly, only one limiting protrusion 24 is provided on the pull handle auxiliary tool 20. In this embodiment, as shown in Figures 4 and 5, a limiting groove 13 is provided at the middle position of both the front horizontal hole wall 111 and the rear horizontal hole wall 111, and correspondingly, as shown in Figures 9 and 10, two limiting protrusions 24 are provided on the pull handle auxiliary device 20.

[0046] Furthermore, the upper surface of the pull handle body 10 is its front surface, and the lower surface of the pull handle body 10 is its back surface. When attaching the pull handle auxiliary tool 20, the auxiliary tool head 23 is inserted into the mounting hole 11 downward, i.e., from the front to the back surface of the pull handle body 10. Preferably, as shown in FIG. 5, the rear surface of the auxiliary tool mounting portion 12 of the pull handle body 10 has receiving grooves 14 on both the front and rear sides of the mounting hole 11 along the length of the pull handle body 10, the receiving grooves 14 communicating with the mounting hole 11, and the rear receiving groove 14 extends directly rearward to the rear edge of the pull handle body 10. When the pull handle auxiliary tool 20 is in the retaining position, as shown in FIG. 2, the longitudinal protrusions 231 on the front and rear ends of the auxiliary tool head 23 are respectively positioned in the front and rear receiving grooves 14, thereby restricting the free rotation and removal of the auxiliary tool head 23 and thus restricting the free rotation and removal of the pull handle auxiliary tool 20, thereby improving the installation reliability of the pull handle auxiliary tool 20. In addition, the accommodation groove 14 is a groove structure on the back surface of the pull handle body 10, and does not affect the appearance of the front surface of the pull handle body 10, preventing the appearance of the pull handle body 10 from having any noticeable protruding parts, thereby ensuring the aesthetic appearance of the pull handle body 10.

[0047] 4 and 5, the groove wall surface of the limiting groove 13 has a first inclined wall surface 131 and a second inclined wall surface 132 that are symmetrically arranged on the left and right sides, and as shown in FIGS. 9 and 10, the outer peripheral surface of the limiting protrusion 24 has a first inclined wall surface 241 and a second inclined wall surface 242 that are symmetrically arranged on the right and left sides. When the pull assisting device 20 is in the holding position, the limiting protrusion 24 is accommodated in the limiting groove 13, and the first inclined wall surface 131 and the first inclined wall surface 241 engage in surface contact, and the second inclined wall surface 132 and the second inclined wall surface 242 engage in surface contact, further improving the tightness between the pull assisting device 20 and the pull handle main body 10 after installation and more reliably restricting left and right rattle of the pull assisting device 20. Preferably, the limiting groove 13 is a triangular groove, i.e., a V-shaped groove, and the limiting protrusion 24 is a triangular protrusion that fits into the limiting groove 13.

[0048] Furthermore, of the pair of lateral hole walls 111, at least one lateral hole wall 111 has a first inclined segment 112 and a second inclined segment 113 arranged symmetrically on the left and right, and the first inclined segment 112 and the second inclined segment 113 are connected to both left and right ends of the limiting groove 13, respectively, and both extend at an incline so that the further away from the limiting groove 13 they are, the further away they are from the lateral center line of the mounting hole 11 in the left-right direction. 4 and 5, each of the pair of horizontal hole walls 111 has a first inclined segment 112 and a second inclined segment 113 arranged symmetrically. Taking the front viewing angle shown in FIG. 4 as an example, in the front horizontal hole wall 111, the first inclined segment 112 on the left side of the limiting groove 13 extends with an inclination toward the front left, and the second inclined segment 113 on the right side of the limiting groove 13 extends with an inclination toward the front right. In the rear horizontal hole wall 111, the first inclined segment 112 on the left side of the limiting groove 13 extends with an inclination toward the rear left, and the second inclined segment 113 on the right side of the limiting groove 13 extends with an inclination toward the rear right. The inclination angles of the first inclined segment 112 and the second inclined segment 113 are small, both about 4°. When the pull aid 20 is in the retaining position, the connection point between the first inclined segment 112 and the limiting groove 13 and the connection point between the second inclined segment 113 and the limiting groove 13 both abut against the outer circumferential surface of the aid post 22. In this way, the four inclined segments on the wall of the mounting hole 11 further improve the tightness between the pull aid 20 and the pull body 10 after installation, thereby strengthening the multi-directional tensile force of the pull aid 20, such as the forward tensile force when closing the zipper, the rearward tensile force when opening the zipper, and the upward tensile force when lifting the pull aid 20 up from the front of the pull body 10. This not only strengthens the tensile test strength of the pull aid 20, but also prevents the pull aid 20 from accidentally coming off the mounting hole 11 during use.

[0049] 7 to 10, the auxiliary tool body 21 includes a pull tab connecting segment 211, an inclined extending segment 212, and a thick-walled gripping segment 213, which are connected in this order from front to back along its length. The auxiliary tool post 22 is provided at the front end of the pull tab connecting segment 211, away from the thick-walled gripping segment 213, and extends up and down along the thickness direction of the auxiliary tool body 21. The inclined extending segment 212 extends at an angle, moving away from the pull tab body 10 as it approaches the thick-walled gripping segment 213, which positions the thick-walled gripping segment 213 away from the surface of the fastener, allowing the user to grip it better. Furthermore, the relatively increased thickness of the thick-walled gripping segment 213 provides the user with a better gripping sensation. The rear surface of the thick-walled gripping segment 213 is provided with a friction-increasing ridge 214 that protrudes slightly downward. When the user grips the rear end of the aid body 21 and pulls the fastener slider back and forth, the friction-increasing ridge 214 increases the frictional force between the aid body 21 and the user's fingers, thereby providing an anti-slip effect.

[0050] Furthermore, the outer contour size of the auxiliary tool head 23 is larger than the contour size of the mounting hole 11; that is, the length size of the auxiliary tool head 23 is larger than the length size of the mounting hole 11, and the width size of the auxiliary tool head 23 is larger than the width size of the mounting hole 11, so that in the pull tab auxiliary tool 20, at least the auxiliary tool head 23 is an elastically deformable body. In this way, by biasing the front end of the pull tab auxiliary tool 20 downward during installation, the auxiliary tool head 23 can be easily passed downward through the mounting hole 11, and after the auxiliary tool head 23 has been passed downward through the mounting hole 11, the auxiliary tool head 23 can be prevented from passing upward through the mounting hole 11 and being removed in the opposite direction. Preferably, as shown in FIG. 9 , the outer peripheral surface of the auxiliary tool head 23 is provided with an installation guide slope 233 that extends at an angle such that the further away from the auxiliary tool post portion 22 it is, the closer it is to the central axis of the auxiliary tool head 23. In this way, when attaching the pull-tab auxiliary tool 20, the inclined attachment guide slope 233 makes it easy to press the auxiliary tool head 23 downwardly through the attachment hole 11, making the attachment operation of the pull-tab auxiliary tool 20 easier.

[0051] Furthermore, the puller body 10 having the above structure is a one-piece molded part and a metal part, preferably a zinc alloy part, which improves the structural strength and durability of the puller body 10. The puller auxiliary element 20 having the above structure is a one-piece molded part and a plastic part, such as a hard plastic part, a soft plastic part, a rubber part, or a resin part, preferably a TPU part, where TPU is thermoplastic polyurethane. This makes the puller auxiliary element 20 easy to manufacture and inexpensive, making it easy to design multiple puller auxiliary elements 20 with different shapes and colors at low cost. Combined with the removable structure of the puller auxiliary element 20 on the puller body 10, it makes it easy for users to replace different puller auxiliary elements 20, enriching the design possibilities of the zipper. Furthermore, even if the puller auxiliary element 20 is damaged during installation and removal, or if it is damaged after a certain period of use, this does not have a significant impact due to the low cost of the puller auxiliary element 20.
