Description

A combined bottom stop, zipper and zipper product

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 3, 2023, with application number 202310972982.X and invention name “A combined bottom stop, zipper and zipper product”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of clothing accessories, and more particularly to a combined bottom stop, a zipper and a zipper product. Background Art

[0003] Zippers are a crucial accessory for clothing and luggage. Zippers are essentially composed of a slider, tape, chain teeth, and a latch (including a bottom stop and a movable latch). Invisible zippers are called invisible zippers because the slider is hidden behind the tape and fabric when used on clothing. When used on a garment's placket, conventional zippers interrupt the fabric's continuity, disrupting the garment's integrity. Invisible zippers, however, maintain a tight connection between the fabric on either side of the chain teeth, ensuring greater fabric continuity.

[0004] Because the zipper tape and the fabric of the garment are located at the front of the invisible zipper, the zipper's bottom stop needs to be hidden behind the slider, making it more difficult to determine whether the pin has been inserted into the correct position. If the user forcibly pulls up the slider without inserting the movable pin into the intended position, the bottom stop block and the movable pin will separate, causing the zipper teeth to pop open. Existing invisible zippers are generally closed zippers. The square pins of open invisible zippers are mostly made of metal, and their insertion and mating structure is relatively simple. This requires the user to insert and position the bottom stop block and the movable pin multiple times, making the invisible zipper's opening and closing process more inconvenient. In addition, the metal bottom stop block can easily injure the user when opening.

[0005] Therefore, how to improve the convenience of closing and closing an open invisible zipper has become a technical problem that needs to be solved urgently by those skilled in the art.

[0047] Another core of the present invention is to disclose a zipper comprising the above-mentioned combined bottom stop.

[0048] Another core of the present invention is to disclose a zipper product, which includes the above-mentioned zipper.

[0049] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0050] In the description of the embodiments of this application, unless otherwise specified, " / " represents or. For example, A / B can represent A or B. "And / or" in this article is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "plurality" means two or more than two.

[0051] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0052] The combined bottom stop disclosed in the embodiment of the present invention is applied to an invisible zipper, and can be named as an invisible zipper combined bottom stop, hereinafter referred to as the combined bottom stop.

[0053] 1 and 2 , the combined bottom stop disclosed in the embodiment of the present invention includes a bottom stop fixing portion 100 and a movable latch 200. The bottom stop fixing portion 100 includes a square fixing portion 110 and a square connecting portion 120. The square fixing portion 110 is provided with a latch receiving slot 113. One end of the square connecting portion 120 is connected to the square fixing portion 110, and the other end is used to connect to the first cloth tape 300.

[0054] 9 , the first end of the movable latch 200 is used to be inserted into and engaged with the latch receiving groove 113, and the second end is used to be connected to the second cloth tape 310. A latch introduction portion 123 is provided at one end of the square connecting portion 120 facing the movable latch 200. The latch introduction portion 123 is an inclined surface structure inclined from the bottom of the latch receiving groove 113 toward the opening.

[0055] During the process of inserting the movable latch 200 into the latch receiving groove 113, the latch introduction portion 123 plays a guiding function. Its cooperation with the pull head can more smoothly guide the movable latch 200 into the latch receiving groove 113, completing the installation of the movable latch 200 and the lower stop fixing portion 100.

[0056] Compared with the prior art, the combined bottom stop disclosed in the embodiment of the present invention adds an introduction structure during the insertion of the movable latch 200 through the latch introduction portion 123, making the insertion and removal of the movable latch 200 smoother, thereby improving the convenience of closing and closing the open invisible zipper.

[0057] In a specific embodiment, as shown in FIG5 , the movable latch 200 includes an insert rod 210 and a latch fixing member 220. The insert rod 210 is configured to engage with the latch receiving slot 113 and guide the assembly process, thereby assembling the movable latch 200 and the lower stop 100.

[0058] The latch fixing member 220 is connected to the insertion rod 210, and a latch gap is defined between the insertion rod 210 and the latch fixing member 220 for sliding engagement with the slider 500. The sliding engagement between the slider 500 and the latch gap allows the movable latch 200 to smoothly pass through the slider fabric seam of the slider 500 until it is inserted into the latch receiving groove 113 of the lower stop fixing portion 100. The latch fixing member 220 is used to connect to the second fabric tape 310, and the second coupling element 410 is disposed on the second fabric tape 310, thereby achieving a connection between the second coupling element 410, the second fabric tape 310, and the movable latch 200.

[0059] Furthermore, in order to limit the specific position of the movable latch 200 when inserted into the latch receiving groove 113, a latch limiting portion 221 is provided on the latch fixing member 220. In conjunction with Figure 5, the latch limiting portion 221 is a functional surface facing the direction of the latch receiving groove 113. When the movable latch 200 is inserted into the specified position in the latch receiving groove 113, the latch limiting portion 221 will be limited by the outer wall of the latch receiving groove 113 to ensure that the movable latch 200 is accurately positioned with the lower stop fixing portion 100.

[0060] 7 , the side wall of the block fixing portion 110 away from the block connecting portion 120 is the insertion limiting portion 114 , and the end surface of the insertion limiting portion 114 facing away from the bottom of the latch receiving groove 113 is used to abut and cooperate with the latch limiting portion 221 for limiting.

[0061] Since the movable latch 200 needs to pass through the slider 500 and then be plugged into the block fixing portion 110, the two sides of the latch gap are connected. In order to further guide the insertion process of the movable latch 200, as shown in Figure 7, a sliding guide portion 112 for embedding into the latch gap is provided on the side wall of the latch accommodating groove 113. When the movable latch 200 passes through the slider 500 and enters the latch accommodating groove 113, the latch gap is aligned with the sliding guide portion 112 and slides together to guide the movable latch 200.

[0062] 7 , the latch receiving groove 113 has limiting side walls for limiting the movable latch 200 in three circumferential directions, and the sliding guide portion 112 has a limiting function for limiting the movable latch 200 in the fourth circumferential direction. The latch receiving groove 113 and the sliding guide portion 112 together form a circumferential limit for the sliding guide portion 112 .

[0063] As shown in FIG8 , when the sliding guide portion 112 extends to the bottom of the latch receiving groove 113 , the width gradually decreases, so as to save materials and reduce product weight without affecting the guiding function.

[0064] The block fixing portion 110 and the block connecting portion 120 can be either a one-piece or split-piece structure. During the production process of a split-piece bottom stop 100, the block connecting portion 120, the first fabric tape 300, and the first coupling element 400 can be assembled first, followed by the block fixing portion 110, to reduce production complexity. Due to its larger size, the one-piece bottom stop 100 is more difficult to assemble with the first fabric tape 300 and the first coupling element 400.

[0065] In order to achieve a fixed connection between the block fixing portion 110 and the block connecting portion 120, as shown in Figure 10, a mounting groove 116 connected to the latch receiving groove 113 is provided on the block fixing portion 110, and an embedded card groove is provided on the side wall of the mounting groove 116. Mounting protrusions 122 are provided on both sides of the block connecting portion 120, and the mounting protrusions 122 are used to be embedded in the embedded card groove.

[0066] The engagement of the retaining protrusion 122 with the retaining groove allows the connection between the block fixing portion 110 and the block connecting portion 120 to be achieved. The block connecting portion 120 can be directly formed on the block fixing portion 110 by injection molding. Referring to FIG. 10 , the retaining protrusion 122 is L-shaped (the portion perpendicular to the extending direction of the block connecting portion 120 is closer to the bottom of the mounting groove 116 than the portion parallel to the block connecting portion 120). The retaining protrusion 122 can also be T-shaped or other similar shapes.

[0067] The clamping protrusion 122 can also be provided on only one side surface of the block fixing portion 110, as long as the connection function can be achieved. The connection strength is higher when the protrusion is arranged on both sides.

[0068] When the block fixing portion 110 and the block connecting portion 120 are split structures, the block fixing portion 110 and the block connecting portion 120 can be combined by secondary molding, as shown in Figure 9. Preferably, the block fixing portion 110 and the block connecting portion 120 are combined by ultrasonic hot melting.

[0069] The block fixing portion 110 and the block connecting portion 120 can also be combined by snapping together. For example, a mounting groove 116 is provided on the block fixing portion 110, and a connecting block slightly larger than the mounting groove 116 is provided on the block connecting portion 120. By squeezing the connecting block into the mounting groove 116, the block fixing portion 110 and the block connecting portion 120 are snapped together.

[0070] 6 and 8 , an extension portion 115 is provided on the end of the block fixing portion 110 facing the slider 500. A sliding gap 121 is formed between the extension portion 115 and the end of the block connecting portion 120 facing away from the movable latch 200, for sliding engagement with the slider 500. When the block connecting portion 120 is fixed to the block fixing portion 110, the sliding gap 121 is formed between the block connecting portion 120 and the extension portion 115. The sliding gap 121 can accommodate the slider base plate, thereby sliding engagement with the slider 500.

[0071] 6 , the extension portion 115 may be connected to the first cloth tape 300 . As shown in FIG10 , the side of the extension portion 115 facing the movable latch 200 also has a latch introduction portion / introduction slope for introducing the movable latch 200 .

[0072] 3 , a positioning hole 111 is provided on the block fixing portion 110 . The positioning hole 111 can be used to insert the end of the block connecting portion 120 and balance the pressure inside and outside the pin receiving groove 113 during the insertion of the movable pin 200 .

[0073] During use, the insert rod 210 of the movable latch 200 is passed through the slider 500 along the slider guide port and inserted into the block fixing portion 110. The insert rod 210 is fixed to the block fixing portion 110 via the latch receiving slot 113 and the sliding guide portion 112 of the block fixing portion 110. The insertion limit portion 114 (the end surface of the block fixing portion 110 facing the slider 500) can limit the movement of the movable latch 200 in the depth direction of the latch receiving slot 113. The positioning hole 113 can limit the horizontal movement of the movable latch 200 in the latch receiving slot 113, thereby greatly improving the stability of the insert rod 210.

[0074] As shown in FIG. 3 and FIG. 4 , the first cloth tape 300 and the second cloth tape 310 are both processed by a bending process.

[0075] The bottom stop fixing portion 100 and the movable latch 200 disclosed in the embodiment of the present invention can both be prepared by injection molding. Injection molding can simplify the production process of the combined bottom stop, improve the physical properties of the invisible zipper, make the product lightweight, facilitate the insertion of the movable latch 200, and make the opening and closing of the invisible zipper smoother.

[0076] The zipper disclosed in the embodiment of the present invention includes the above-mentioned combined bottom stop, and therefore also has the above-mentioned advantages, which will not be described in detail here.

[0077] In one embodiment, the square fixing portion 110 is connected to the first cloth tape 300 , and the square connecting portion 120 is connected to the first link element 400 ; the inserting rod 210 of the movable latch 200 is connected to the second link element 410 , and the latch fixing member 220 is connected to the second cloth tape 310 .
