Tethered haptic tab and puller

Abstract

The application relates to a string loop puller and a puller head, the string loop puller comprising a main plate and a back plate, the back plate being connected to the back side of the main plate, and the main plate and the back plate being spaced apart in the thickness direction of the main plate to form a string passing hole, the edge of the back plate being concavely provided with two spaced-apart limiting grooves, and the two limiting grooves being communicated with the string passing hole to form a string passing channel. In the above scheme, the string loop is not easy to slide after being tied, and the diameter of the string body is no longer limited by the connecting gap between the main plate and the puller body, thereby avoiding the problem that the connection between the string loop puller and the puller body is easily blocked due to the interference caused by the too thick string body. Meanwhile, the string body is hidden at the back side of the main plate, and the string loop is invisible when the string loop puller is viewed from the front side of the main plate, thereby increasing the aesthetic degree of the string loop puller when viewed from the front side.

Description

Technical Field

[0001] This application relates to the field of zipper technology, and in particular to cord loop pull tabs and zipper heads. Background Technology

[0002] With the widespread use of zippers in bags, clothing, outdoor equipment and other fields, the drawstring pull tab, as a key component for the functionality and decoration of zippers, directly affects the user's operating experience and the overall aesthetics of the product due to the rationality and reliability of its structural design.

[0003] Currently, the rope loop technology in the industry is mainly based on two traditional solutions: one is a bottom-end front-hole knotted structure, which uses a through hole at the bottom of the pull tab to directly thread the rope and tie a knot to achieve fixation; the other is a longitudinal loop back knotted design, which uses a longitudinal hole at the bottom of the pull tab to form a loop structure, and the rope is threaded in and then folded back to tie a knot.

[0004] However, existing technologies have significant limitations in practical applications. For the first bottom-perforation scheme, the differences in friction coefficients and inconsistent diameters of the rope materials (such as nylon, polyester, and elastic fibers), coupled with the lack of an effective restraint mechanism at the knot end, cause the rope loop to easily slide circumferentially along the perforation and easily loosen and fall off. While the second longitudinal loop scheme avoids the sliding problem through a loop structure, the tolerance range for the inner diameter of the loop and the rope diameter is narrow. When the rope diameter exceeds a certain threshold, it easily leads to jamming at the loop edge or rope wear and breakage. More significantly, both schemes require exposed knot structures, creating a visually disjointed look for the zipper and failing to meet the concealed aesthetic requirements of high-end products. These technical pain points collectively point to the systemic deficiencies of existing rope loop structures in terms of mechanical adaptability, process compatibility, and aesthetic expression, urgently requiring breakthroughs through innovative structural design. Utility Model Content

[0005] Therefore, it is necessary to provide a new type of cord loop pull tab and zipper pull to address the problems of easy slippage and loosening, limited cord size, and exposed cord knots affecting the appearance of existing zipper cord loop pull tabs.

[0006] A tethering loop includes a main board and a back plate. The back plate is connected to the back side of the main board, and the main board and the back plate are spaced apart in the thickness direction of the main board to form a tethering hole. The edge of the back plate is recessed with two spaced limiting grooves, and both limiting grooves are connected to the tethering hole to form a tethering channel.

[0007] In one embodiment, the tether loop pull tab further includes a connecting plate, one end of which is connected to the back side of the main board and the other end of which is connected to the back plate. The two connecting plates are spaced apart so that the two connecting plates, the main board, and the back plate together form the tether hole.

[0008] In one embodiment, the two limiting grooves are arranged symmetrically along the axial direction of the rope threading hole.

[0009] In one embodiment, the projection of the backplate in the thickness direction of the motherboard lies within the projection of the motherboard in the thickness direction of the motherboard.

[0010] In one embodiment, the motherboard includes a connecting end and a tethering end connected together, the backplate is connected to the tethering end, and the projection of the backplate in the thickness direction of the motherboard is located within the projection of the tethering end in the thickness direction of the motherboard.

[0011] In one embodiment, the limiting groove is closer to the connecting end than the rope hole, and the distribution direction of the connecting end and the rope-tying end is the same as the axial direction of the rope hole.

[0012] In one embodiment, the motherboard is a single-piece structure.

[0013] In one embodiment, the connection end has a connection hole that extends through the connection end in the thickness direction of the motherboard.

[0014] In one embodiment, the depth direction of the limiting groove is perpendicular to the axial direction of the rope threading hole.

[0015] A zipper puller includes a cord loop pull tab as described in any of the above embodiments, and a pull body, wherein the main board is connected to the pull body, and the cord hole is located at one end of the cord loop pull tab away from the pull body.

[0016] The tether loop pull tab provided in the above solution features a tether hole between the back plate and the main plate, and a limiting groove on the circumferential surface of the back plate. This creates an angle between the limiting groove and the tether hole, preventing the tether loop from slipping after being secured. Furthermore, the tether channel through which the tether passes does not intersect with the part connecting the main plate to the pull body. The diameter of the tether is no longer limited by the connection gap between the main plate and the pull body, avoiding the problem of interference and jamming caused by an excessively thick tether. Simultaneously, with the back plate located on the back side of the main plate and the tether hole between the main plate and the back plate, the tether is hidden on the back side of the main plate when the tether is passed through the tether channel. When viewed from the front of the main plate, the tether loop is not visible, thus increasing its aesthetic appeal when viewed directly. Attached Figure Description

[0030] See Figure 1 , Figure 1 A schematic diagram of the structure of a zipper pull 10 according to one embodiment of this application is shown. The zipper pull 10 provided in one embodiment of this application includes a cord loop pull tab 100 as described in any of the following embodiments, and also includes a pull body 200. The pull body 200 engages with chain teeth, so that the chain teeth can be engaged and disengaged by moving the pull body 200. Figure 1As shown, the main board 110 of the tether loop pull tab 100 is connected to the pull body 200. In this embodiment, the pull body 200 is provided with a hole for connecting the tether loop pull tab 100. One end of the tether loop pull tab 100 passes through the hole and can be movably disposed within the hole.

[0031] Combination Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 A schematic diagram of the structure of a tether loop pull tab 100 according to an embodiment of this application is shown. This embodiment provides a tether loop pull tab 100, which includes a main plate 110 and a back plate 120. The main plate 110 is used to connect to the aforementioned pull body 200. For example... Figure 2 and Figure 3 As shown, the backplate 120 is connected to the back side of the motherboard 110, and as... Figure 2 As shown, the motherboard 110 and the backplate 120 are spaced apart in the thickness direction of the motherboard 110 to form lanyard holes 141. The edge of the backplate 120 is recessed with two spaced-apart limiting grooves 142, both of which communicate with the lanyard holes 141 to form a lanyard channel 140. (Combined) Figure 4 and Figure 5 As shown, the rope 20 can be threaded through the rope channel 140. In this embodiment, the two ends of the rope 20 enter the rope hole 141 through two limiting grooves 142 and exit from the rope hole 141. Since the limiting groove 142 is opened at the edge of the back plate 120, there will be an angle between it and the rope hole 141 between the main plate 110 and the back plate 120. Under the limiting action of the limiting groove 142, the rope loop is not easy to slip after being tied. Moreover, the rope channel 140 through which the rope 20 passes does not intersect with the part of the main plate 110 connected to the pull body 200. The diameter of the rope 20 is no longer limited by the connection gap between the main plate 110 and the pull body 200, avoiding the problem of the rope loop pull piece 100 and the pull body 200 being easily jammed due to the rope 20 being too thick.

[0032] Meanwhile, since the back plate 120 is located on the back side of the main board 110 and the lanyard hole 141 is located between the main board 110 and the back plate 120, when the lanyard 20 is threaded through the lanyard channel 140, the lanyard 20 is hidden on the back side of the main board 110. When the lanyard loop pull tab 100 is viewed from the front of the main board 110, the lanyard loop is not visible, thereby increasing the aesthetic appeal of the lanyard loop pull tab 100 when viewed from the front.

[0033] like Figure 3 As shown, in this embodiment, the main board 110 and the back plate 120 are arranged in parallel, and in this embodiment, both the main board 110 and the back plate 120 are parallel to the axial direction of the rope hole 141, so that the overall appearance of the rope loop pull piece 100 is aesthetically pleasing and easy to manufacture and install.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment, the tether loop pull tab 100 further includes a connecting plate 130, one end of which is connected to the back side of the main board 110, and the other end is connected to the back plate 120, in combination with... Figure 5 As shown, two connecting plates 130 are spaced apart so that the two connecting plates 130, the main plate 110, and the back plate 120 together form a lanyard hole 141. In other embodiments, the main plate 110 and the back plate 120 can be directly connected, and their opposite end faces are respectively provided with grooves for joining together to form the lanyard hole 141.

[0035] like Figures 2 to 3 As shown, in this embodiment, the connecting plate 130 and the back plate 120 are an integral structure, but this is not a limitation. In other embodiments, they can also be separate structures.

[0036] like Figures 2 to 5 As shown, in one embodiment, two limiting grooves 142 are symmetrically arranged along the axial direction of the rope hole 141 so that the force between the rope 20 and the back plate 120 is uniform after the rope 20 passes through the rope channel 140.

[0037] like Figure 3 and Figure 4 As shown, in one embodiment, the projection of the back plate 120 in the thickness direction of the motherboard 110 is located within the projection of the motherboard 110 in the thickness direction of the motherboard 110, so that the back plate 120 can be completely hidden on the back side of the motherboard 110, thereby enabling the motherboard 110 to cover the back plate 120 and the rope 20 connected to the back plate 120, thereby increasing the aesthetics of the tether loop pull tab 100 when viewed from the front.

[0038] In one embodiment, the main board 110 includes a connecting end 111 and a tethering end 112 connected together. The connecting end 111 is used to connect to the aforementioned pull body 200, and the tethering end 112 is located on the side of the connecting end 111 away from the pull body 200. Furthermore, in this embodiment, the tethering hole 141 is located at the end of the tethering loop pull tab 100 away from the pull body 200 to prevent the rope 20 from interfering with the connection between the connecting end 111 and the pull body 200 when it passes through the tethering channel 140.

[0039] The back plate 120 is connected to the tether end 112, and the projection of the back plate 120 in the thickness direction of the main board 110 lies within the projection of the tether end 112 in the thickness direction of the main board 110. This allows the back plate 120 to be completely hidden behind the tether end 112, thus enabling the tether end 112 to cover the back plate 120 and the rope 20 connected to the back plate 120, thereby increasing the aesthetics of the tether loop pull tab 100 when viewed from the front. In this embodiment, the projections of the tether end 112 and the back plate 120 in the thickness direction of the main board 110 are both circular structures. In other embodiments, the projections of the tether end 112 and the back plate 120 in the thickness direction of the main board 110 can also be other polygonal structures, elliptical structures, etc. In other embodiments, the projections of the tether end 112 and the back plate 120 in the thickness direction of the main board 110 can also be different.

[0040] In one embodiment, the motherboard 110 is a single-piece structure. For example, the motherboard 110 can be integrally molded or fixedly connected together after molding. In other embodiments, the motherboard 110 can also be a detachable structure.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, the limiting groove 142 is closer to the connecting end 111 than the rope hole 141, and the distribution direction of the connecting end 111 and the rope-tying end 112 is in the same direction as the axial direction of the rope hole 141. After the rope 20 passes through the limiting groove 142, it passes through the rope hole 141 along the axial direction of the rope hole 141. At this time, the rope 20 is located away from the connecting end 111 to avoid the rope 20 interfering with the fit between the connecting end 111 and the pull body 200.

[0042] In one embodiment, the connecting end 111 has a connecting hole 1111, which extends through the connecting end 111 in the thickness direction of the main board 110. The connecting hole 1111 is used to connect the pull body 200. The pull body 200 partially passes through the connecting hole 1111, so that the pull body 200 and the main board 110 can rotate and move relative to each other. The rope passage 140 through which the rope 20 passes does not intersect with the connecting hole 1111. The diameter of the rope 20 is no longer limited by the connection gap between the main board 110 and the pull body 200, thus avoiding the problem of interference and easy jamming between the rope loop pull piece 100 and the pull body 200 due to the rope 20 being too thick.

[0043] like Figure 2As shown, in one embodiment, the depth direction of the limiting groove 142 is perpendicular to the axial direction of the rope hole 141, so that when force is applied to the rope 20 after it passes through the rope hole 141, the rope 20 tends to adhere to the groove wall of the limiting groove 142, thereby making it less likely for the rope loop to slip after it is tied. In other embodiments, the depth direction of the limiting groove 142 may also be inclined relative to the axial direction of the rope hole 141 towards the direction closer to the pull body 200.

[0044] The tether loop pull tab 100 provided in the above solution has a tether hole 141 between the back plate 120 and the main plate 110, and a limiting groove 142 on the circumferential surface of the back plate 120. This creates an angle between the limiting groove 142 and the tether hole 141. Under the limiting effect of the limiting groove 142, the tether loop is not easy to slip after being tied. Furthermore, the tether channel 140 through which the rope 20 passes does not intersect with the part of the main plate 110 that connects to the pull body 200. The diameter of the rope 20 is no longer limited by the connection gap between the main plate 110 and the pull body 200. This avoids the problem of the tether loop pull tab 100 and the pull body 200 being easily jammed due to interference caused by the rope 20 being too thick. Meanwhile, the back plate 120 is located on the back side of the main board 110, and the lanyard hole 141 is located between the main board 110 and the back plate 120. When the lanyard 20 is threaded through the lanyard channel 140, the lanyard 20 is hidden on the back side of the main board 110. When the lanyard loop pull tab 100 is viewed from the front of the main board 110, the lanyard loop is not visible, thereby increasing the aesthetic appeal of the lanyard loop pull tab 100 when viewed from the front.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
