Description

Technical Field

[0001] This invention relates to the field of zipper-related technology, and in particular to an article containing a zipper. Background Technology

[0002] With the continuous advancement of zipper manufacturing technology, in order to make zipper products lighter and more flexible, the fabric strap in traditional zippers has been eliminated, and the zipper teeth are directly installed onto the clothing fabric. However, the shape, size, thickness, and density of ordinary fabrics differ significantly from those of traditional fabric straps. Directly installing the zipper teeth onto the fabric may result in problems such as insecure installation, unstable tooth spacing, and fabric arching. Therefore, improvements have been made to zipper products without fabric straps and the tooth installation method. For example, Chinese invention patent CN115515455A discloses a zipper product and its installation method. Figure 12 As shown, the zippered product includes a zipper tooth component 10 and a zipper mounting component 11. The zipper tooth component 10 is formed by mounting zipper teeth 13 onto a fixing component 12. The zipper mounting component 11 has a zipper tooth mounting edge 14 for mounting the zipper tooth component 10. A gap 15 is formed between the main body portions of adjacent zipper teeth 13 along the length direction to expose the fixing component 12. It also includes a fixing sewing part 17, by which the zipper tooth component 10 is sewn to the zipper mounting component 11. The fixing component 12 is held by being pressed by the first sewing line 18 of the fixing sewing part 17, and one side wall of the zipper tooth 13 abuts against the zipper mounting component 11. It is easy to see that the zipper products produced using this installation method only connect the fixing component 12 and the zipper tooth mounting edge 14 through the stitching, while the zipper tooth 13 and the zipper mounting component 11 are just leaning against each other. During use, the small zipper teeth are easy to shift or flip, which affects the stability of the zipper. Summary of the Invention

[0003] To address the issue of how to stably install zipper components onto fabric (ornaments), this invention, combining the features of existing technologies, proposes an improved zipper-containing product, comprising fabric and a zipper arranged on the fabric. Using the XYZ coordinate system as a reference, the zipper includes two rows of zipper teeth arranged along the X-axis and a slidable slider mounted on the two rows of zipper teeth. The zipper teeth in each row are spaced apart. The slider has side wings and fabric seams on both sides, and a zipper channel for the zipper to slide through is provided between the two side wings. The zipper teeth are divided into a front, middle, and tail section along the Y-axis. The front section of the zipper teeth has interlocking teeth to allow for forward or reverse rotation. When the zipper pull is pulled, the two rows of chain teeth can engage or disengage in the zipper channel; it also includes a front connector and a rear connector, the front connector being connected to the middle or front of the chain teeth, and the rear connector being connected to the tail of the chain teeth. A first seam passes through the fabric and binds the front connector to achieve front positioning of the chain teeth and form a front binding point at the overlap between them. A second seam passes through the fabric and binds the rear connector to achieve rear positioning of the chain teeth and form a rear binding point at the overlap between them. In the Y-axis direction, the front binding point and the rear binding point are spaced apart from each other.

[0004] The fabric is a component used to provide a connection base for the zipper, and can be cloth or leather, and its shape can be strip or sheet.

[0005] The zipper is composed of multiple teeth arranged at intervals along the Y-axis. Furthermore, the teeth arranged at intervals can be connected together by the front connector and the rear connector mentioned below to form a series of teeth.

[0006] The zipper pull is a component slidably connected to the zipper. It includes an upper plate and a lower plate arranged at an interval, with a connecting post between the upper and lower plates. Side wings are provided on the left and right sides of the upper plate and / or the lower plate, and the side wings can be divided into a left wing and a right wing. The upper plate, lower plate, left wing, and right wing define the zipper channel. The side wings can be configured in at least three ways: first, the side wing is connected to the upper plate; second, the side wing is connected to the lower plate; third, the side wing on the same side is divided into upper and lower parts, which are simultaneously connected to the upper plate and the lower plate respectively.

[0007] The fabric seam refers to a slit-like gap located on the left and right sides of the zipper head, allowing fabric, stitching, or part of the chain tooth extension component (as mentioned below, the straight arm portion) to pass through. The fabric seam can be formed in at least the following ways: First, the upper end of the side wing is connected to the upper plate, and the lower end forms the fabric seam with the lower plate; Second, the lower end of the side wing is connected to the lower plate, and the upper end forms the fabric seam with the upper plate; Third, the side wing is divided into upper and lower parts, the upper part is connected to the upper plate, the lower part is connected to the lower plate, and the upper and lower parts are disconnected in the middle to form the fabric seam.

[0008] The front connector and rear connector refer to two connecting components attached to the zipper teeth near the front and rear, respectively. The front and rear connectors have at least two functions: first, to connect adjacent zipper teeth, forming a zipper chain; second, to connect with the first or second seam mentioned later, securing the zipper to the fabric. The specific implementation of the front and rear connectors is varied. One type uses a core thread made of twisted synthetic fibers or natural silk threads, with multiple zipper teeth mounted and fixed on the core thread to form the zipper; another type uses plastic connecting components, injection molded together with the zipper teeth. Of course, to connect multiple zipper teeth together, at least one connector connects adjacent zipper teeth, while the other connector is attached to one side of the zipper teeth.

[0009] The front binding point and the rear binding point are the binding points where the first seam, the second seam, and the zipper are bound together, respectively. These points are spaced apart on the Y-axis. It should be noted that since the seam and the zipper are continuously bound together in the X-axis direction, the first seam, the second seam, and the zipper will form multiple binding points in a continuous and neat arrangement in the X-axis direction. However, the distribution of these binding points on the Y-axis is roughly located at two positions arranged front and back. Therefore, the front binding point and the rear binding point do not refer to only two binding points, but rather to the collective term for multiple binding points distributed front and back on the Y-axis when the two seams are bound to the zipper.

[0010] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) The front connector and / or the rear connector can not only form a chain of teeth, thus facilitating the manufacturing, storage, transportation and subsequent installation of the chain teeth themselves, but also form a first binding connection with the fabric by means of the front connector, the first seam, and the fabric. Secondly, the rear connector and the second seam can form a second binding connection with the fabric. Moreover, the two binding connections are placed at two different positions separated by the front and rear in the Y-axis direction, thereby forming two fixings for the zipper. The synergistic effect of the two binding connection structures makes it difficult for the chain teeth to flip, greatly improving the stability of the zipper; (2) By setting two binding connection points at the front and rear, the connection density and connection strength between the zipper and the fabric can be increased. When the chain teeth are subjected to separation tension, the tension can be dispersed through multiple binding connection points, which is beneficial to reduce the local stress deformation of the fabric and the displacement of the chain teeth. (3) By setting the rear connector at the tail of the chain tooth, the main body of the chain tooth is extended backward. The rear connector can press against the fabric, which not only simplifies the binding difficulty of the second stitch, but also increases the contact surface between the chain tooth and the fabric, further improving the connection stability between the chain tooth and the fabric.

[0011] The specific structures of the front connector and the rear connector are further described below.

[0012] The front connector includes a first connecting line that connects to the middle or front of the chain teeth. Adjacent chain teeth in a row along the X-axis are connected in a chain by the first connecting line. A first stitch passes through the fabric and binds the first connecting line, thereby achieving front positioning of the chain teeth and forming a front binding point at the overlap between them. When the zipper pull is pulled, the front binding point is arranged to pass through the zipper channel when viewed from the X-axis direction. The first connecting line refers to a section of thread connecting two adjacent chain teeth, and the first connecting line is generally exposed to allow the first stitch to bind together.

[0013] Furthermore, the front connector includes a first connecting core wire extending in the X-axis direction, with multiple chain teeth connected in series and fixed on a first connecting core wire to form a row of chain teeth, and the first connecting core wires that are empty between adjacent chain teeth forming the first connecting wire body.

[0014] The specific structure of the rear connector is quite flexible, and the following describes three specific implementation methods.

[0015] In the first embodiment, the rear connector includes a second connecting line that connects to the tail of the chain tooth. In a row of chain teeth, adjacent chain teeth in the X-axis direction are connected in a string by the second connecting line. A second stitch passes through the fabric and binds the second connecting line to achieve rear positioning of the chain teeth and form the rear binding joint point at the overlapping part between them.

[0016] The second type includes a tail shank and a second connecting core extending in the X-axis direction. The tail shank includes a straight arm extending in the Y-axis direction and connected to the tail of the chain tooth. Viewed from the X-axis direction, at least a portion of the straight arm extends from the side seam of the zipper pull. The second connecting core is located outside the side wing of the zipper pull. The straight arm is combined with the tail of the chain tooth, forming a stepped stop in the YZ coordinate on the upper and / or lower side of the straight arm. The second seam passes through the fabric and binds the second connecting core that is empty between the straight arm and / or adjacent straight arms to achieve the rear positioning of the chain tooth. The overlap between the second seam and the second connecting core that is empty between the straight arm and / or adjacent straight arms forms the rear binding joint point.

[0017] The third type includes a tail shank, which includes a straight arm extending along the Y-axis and connected to the tail of the chain tooth. Viewed from the X-axis, at least a portion of the straight arm extends from the side seam of the zipper pull, and the straight arm combines with the tail of the chain tooth to form a stepped stop in the YZ coordinate on the upper and / or lower side of the straight arm. The second seam passes through the fabric and binds the straight arm to achieve the rear positioning of the chain tooth and forms the rear binding joint point at the overlap between them.

[0018] Furthermore, the rear connector includes a tail shank, which includes a straight arm extending along the Y-axis and connected to the tail of the chain tooth, and a bent arm connecting the straight arm. The straight arm and the bent arm are combined in a bend or T-shape. Viewed from the X-axis, at least a portion of the straight arm extends from the side seam of the zipper pull. Moreover, the straight arm, combined with the tail of the chain tooth, forms a stepped stop at the YZ coordinate on the upper and / or lower side of the straight arm. A second seam passes through the fabric and binds the straight arm and / or the bent arm to achieve rear positioning of the chain tooth. The overlap between the second seam and the straight arm and / or the bent arm forms the rear binding point.

[0019] To ensure the second thread securely binds the rear connector, two spaced-apart tail shanks are further provided behind the chain teeth. The bent arms of the two tail shanks are connected to each other as a single unit, forming a door frame shape. This makes it difficult for the second thread to slip off the tail shanks. Furthermore, stitching recesses are provided on the straight or bent arms of the tail shanks. When the thread is bound in these recesses, the connection stability between the thread and the tail shanks is further improved, which helps reduce chain tooth slippage.

[0020] Because of the above-mentioned features and advantages, the present invention can be applied to the aforementioned articles containing zippers. Attached Figure Description

[0033] The structure of the zipper-containing article applying the technical solution of the present invention will be further described below with reference to the accompanying drawings. Except where explicitly stated to be equivalent or alternative embodiments, the various implementation details disclosed below may be selectively applied or combined in a single embodiment even if they are not directly related or synergistic in function.

[0034] like Figures 1-3 As shown, this invention presents a zipper-containing product, comprising a fabric 1 and a zipper 2 arranged on the fabric 1. With reference to coordinates XYZ, the zipper 2 includes two rows of chain teeth 3 arranged along the X-axis and a slidable slider 4 mounted on the two rows of chain teeth 3. The chain teeth 3 in a row are spaced apart from each other. The slider 4 has side wings and fabric seams 41 on its left and right sides, and a zipper channel 40 between the two side wings for the zipper 2 to slide through. Along the Y-axis, the chain teeth 3 are divided into a front portion H1, a middle portion H2, and a tail portion H3. The front portion H1 of the chain teeth 3 has interlocking teeth 31 so that when the slider 4 is pulled forward or backward, the two rows of chain teeth can slide through. The teeth 3 engage or disengage in the zipper channel 40; it also includes a front connector and a rear connector, the front connector being connected to the middle H2 or front H1 of the teeth 3, and the rear connector being connected to the tail H3 of the teeth 3. A first seam 61 passes through the fabric 1 and binds the front connector to achieve front positioning of the teeth 3 and forms a front binding point K at the overlap between them. A second seam 62 passes through the fabric 1 and binds the rear connector to achieve rear positioning of the teeth 3 and forms a rear binding point J at the overlap between them. In the Y-axis direction, the front binding point K and the rear binding point J are spaced apart from each other.

[0035] The XYZ coordinate system is used to define the structure of the product. In this embodiment, the X-axis is the direction in which the zipper teeth 3 are arranged, the Y-axis is the direction in which a single zipper tooth 3 extends, i.e., the front-to-back extension direction of the zipper tooth 3, and the Z-axis is the direction of the thickness of the zipper tooth 3. "In the Y-axis direction" means that what is observed along the Y-axis is the arrangement of the zipper 2 or zipper teeth 3 in the XZ plane.

[0036] like Figure 1 and Figure 2As shown, the zipper pull 4 is a component slidably connected to the zipper 2. It includes an upper plate 42 and a lower plate 43 arranged at intervals. A connecting post (not shown in the figure) is also provided between the upper plate 42 and the lower plate 43. In this embodiment, the side wings are provided on the left and right sides of the lower plate 43. The side wings can be divided into a left wing 44 and a right wing 45. The upper plate 42, the lower plate 43, the left wing 44, and the right wing 45 define the zipper channel 40. Of course, in other equivalent embodiments, the left wing 44 and the right wing 45 can also be connected to the upper plate 42, or they can be divided into upper and lower parts and connected to the upper plate 42 and the lower plate 43 respectively. Further, in this embodiment, the left wing 44 and the right wing 45 are separated from the upper plate 42 by a slit-like gap that allows the fabric 1, the seam, or part of the zipper tooth 3 extension member (the straight arm part mentioned below) to pass through. This gap is the fabric seam 41. The left wing 44 and the right wing 45 are the left and right limiting structures of the zipper head 4. In order for the zipper head 4 to slide smoothly and stably on a pair of zippers 2, the left wing 44 and the right wing 45 are generally arranged outside the middle H2 or the tail H3 of a row of chain teeth 3, so that the zipper head 4 can slide along the arrangement direction (Y-axis direction) of the chain teeth 3.

[0037] The specific structures of the front connector and the rear connector are further described below using two specific embodiments.

[0038] The first embodiment, such as Figures 2-6 As shown, the front connector includes a first connecting line 51 that connects to the middle H2 of the chain teeth 3. Adjacent chain teeth 3 in the X-axis direction are connected in a string via the first connecting line 51. A first stitch 61 passes through the fabric 1 and binds the first connecting line 51, thereby achieving the front positioning of the chain teeth 3 and forming the front binding point K at the overlap between them. When the zipper pull 4 is pulled, from the X-axis direction, the front binding point K is arranged to pass through the zipper channel 40. The first connecting line 51 refers to a section of thread connecting two adjacent chain teeth 3. The first connecting line 51 is generally exposed to allow the first stitch 61 to bind together; it can be a small independent section or a part of a long core wire. Since the left wing 44 and right wing 45 are located outside the middle H2 or tail H3 of the chain teeth 3, the first connecting line 51 connected to the middle H2 of the chain teeth 3 must pass through the zipper channel 40 when the zipper pull 4 passes by.

[0039] In this embodiment, the front connector includes a first connecting core wire 5 extending in the X-axis direction, a plurality of chain teeth 3 are connected in series and fixed on a first connecting core wire 5 to form a row of chain teeth 3, and the first connecting core wire 5 that is left empty between adjacent chain teeth 3 forms the first connecting wire body 51.

[0040] The rear connector includes a tail shank 7, which includes a straight arm 71 extending along the Y-axis and connected to the tail H3 of the chain tooth 3. Viewed from the X-axis, at least a portion of the straight arm 71 extends from the side seam 41 of the zipper pull 4, and the straight arm 71 combines with the tail H3 of the chain tooth 3 to form a stepped stop in the YZ coordinate on the upper and / or lower side of the straight arm 71. The second seam 62 passes through the fabric 1 and binds the straight arm 71 to achieve rear positioning of the chain tooth 3 and forms the rear binding joint J at the overlap between them. The stepped stop can be arranged in at least three ways (the same applies below): First, the stepped stop is arranged on the upper side of the straight arm 71 to form an upper step 63; second, the stepped stop is arranged on the lower side of the straight arm 71 to form a lower step 64; third, the stepped stop is arranged on both the upper and lower sides of the straight arm 71 to form an upper step 63 and a lower step 64 respectively. The stepped stop has two main functions: first, it is used for positioning and bonding with the fabric 1; second, it provides storage space for the sewing thread, reducing contact and friction between the sewing thread and other components. This embodiment uses the third arrangement, where the lower step 64 is used to bond with the fabric 1, and the second sewing thread 62, when tied to the straight arm 71, falls precisely on the upper step 63.

[0041] Furthermore, the rear connector includes a tail shank 7, which includes a straight arm 71 extending along the Y-axis and connected to the tail H3 of the chain tooth 3, and a bent arm 72 connecting the straight arm 71. The straight arm 71 and the bent arm 72 are combined in a bend or T-shape. From the X-axis direction, at least a portion of the straight arm 71 extends from the side seam 41 of the pull head 4, and the straight arm 71 is combined with the tail H3 of the chain tooth 3 to form a stepped stop in the YZ coordinate on the upper and / or lower side of the straight arm 71. The second seam 62 passes through the fabric 1 and binds the straight arm 71 and / or the bent arm 72 to achieve the rear positioning of the chain tooth 3. The overlap between the second seam 62 and the straight arm 71 and / or the bent arm 72 forms the rear binding joint point J. The straight arm 71 and the bent arm 72 of the tailstock 7 are combined in a T-shape, which makes it difficult for the stitching attached to the straight arm 71 to come loose. The straight arm 71 and the bent arm 72 of the tailstock 7 can also be combined in a bend shape, that is, in a figure-7 or L-shape (not shown in the figure), which has the same technical effect as the T-shape.

[0042] In order for the second seam 62 to securely and stably bind the rear connector, such as Figures 6-7As shown, two tail shanks 7 are arranged at a left-right interval behind the chain tooth 3. The bent arm portions 72 of the two tail shanks 7 are connected to each other as a whole, and the two tail shanks 7 are combined to form a door frame shape. At this time, it is difficult for the second stitch 62 to come off the tail shank 7. Furthermore, a stitching pit 73 is provided on the straight arm portion 71 or the bent arm portion 72 of the tail shank 7. When the stitch is tied in the stitching pit 73, the connection stability between the stitch and the tail shank 7 is further improved, which helps to reduce the slippage of the chain tooth 3.

[0043] The second embodiment, such as Figures 2-3 , Figures 7-11 As shown, multiple chain teeth 3 are connected and fixed on the first connecting core wire 5 to form a row of chain teeth 3. The first connecting core wire 5 that is left empty between adjacent chain teeth 3 forms the first connecting line body 51. The difference from the first embodiment is that the first connecting line body 51 is connected to the front part H1 of the chain tooth 3. The first sewing thread 61 passes through the fabric 1 and binds the first connecting line body 51 to achieve the front positioning of the chain tooth 3.

[0044] The rear connector includes a second connecting line 81 that connects to the tail H3 of the chain tooth 3. The chain teeth 3 adjacent to each other in the X-axis direction in a row of chain teeth 3 are connected in a string by the second connecting line 81. The second stitch 62 passes through the fabric 1 and binds the second connecting line 81 to achieve the rear positioning of the chain teeth 3 and form the rear binding joint point J at the overlapping part between them.

[0045] Furthermore, the rear connector includes a tail shank 7 and a second connecting core 8 extending in the X-axis direction. The tail shank 7 includes a straight arm portion 71 extending in the Y-axis direction and connected to the tail portion H3 of the chain tooth 3. Viewed from the X-axis direction, at least a portion of the straight arm portion 71 extends from the side seam 41 of the zipper pull 4. The second connecting core 8 is located outside the side wing of the zipper pull 4, and the straight arm portion 71 combines with the tail portion H3 of the chain tooth 3 to form a stepped stop in the YZ coordinate on the upper and / or lower sides of the straight arm portion 71. A second seam 62 passes through the fabric 1 and binds the second connecting core 8 that is empty between the straight arm portion 71 and / or adjacent straight arm portions 71 to achieve rear positioning of the chain tooth 3. The overlap between the second seam 62 and the second connecting core 8 that is empty between the straight arm portion 71 and / or adjacent straight arm portions 71 forms the rear binding joint point J. Figure 10 and Figure 11As shown, the tail shank 7 also includes a bent arm 72 connected to the tail end of the straight arm 71. The tail shank 7 is T-shaped. The second connecting core wire 8 is connected to the bent arm 72. When the second sewing thread 62 is tied to the straight arm 71, the second connecting core wire 8 and the bent arm 72 can prevent the second sewing thread 62 from coming off the straight arm 71, effectively improving the connection stability between the chain tooth 3 and the fabric 1.
