Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the present application discloses a light slide fastener 100, which includes at least two fastener tapes, for example, only two fastener tapes may be included, or three or more fastener tapes may be included. For example, fig. 1 shows a slide fastener 100 including a first fastener tape 1, a second fastener tape 2, and an intermediate joining fastener tape 3. Each chain belt extends along the axial direction, and all the chain belts are arranged at intervals along the direction perpendicular to the axial direction. Wherein, there is the interval space 6 between first chain belt 1 and the second chain belt 2, and middle joining chain belt 3 sets up in interval space 6. The intermediate connecting belt 3 is a tape having a certain width, for example, 10cm or 15 cm.

A set of chain teeth is arranged between two adjacent chain belts. Specifically, the light slide fastener 100 including three fastener tapes shown in fig. 1 includes a first set of fastener elements disposed between the first fastener tape 1 and the intermediate joining fastener tape 3, and a second set of fastener elements disposed between the second fastener tape 2 and the intermediate joining fastener tape 3; the first suit tooth group and the second suit tooth group respectively comprise male tooth elements (31, 32) and female tooth elements (10, 20) which can be used in a penetrating and sleeving matching mode. The male fastener elements (31, 32) are respectively disposed on the left and right sides in the transverse direction (perpendicular to the axial direction) of the intermediate joining fastener tape 3, the female fastener element 10 is disposed on the inner side edge of the first fastener tape 1, and the female fastener element 20 is disposed on the inner side edge of the second fastener tape 2.

As shown in fig. 1 and 2, the male elements (31, 32) disposed on the left and right sides in the transverse direction of the intermediate joining chain belt 3 are not integrally formed but are disposed at intervals in the transverse direction. Thus, the intermediate connecting belt 3 can be exposed between the male elements (31, 32) on both left and right sides in the transverse direction of the intermediate connecting belt 3, and the intermediate connecting belt 3 can provide an optimum layout space for arranging decorative elements such as a text or pattern layer. When the character or pattern layer is provided on the intermediate connecting fastener tape 3, the intermediate connecting fastener tape 3 becomes a slide decorative tape disposed between the first fastener tape 1 and the second fastener tape 2, and the appearance of the slide fastener can be enriched.

In other embodiments, the male and female elements may be interchanged, as described in more detail below. For ease of distinction, the different slide fasteners are labeled as

slide fasteners

100a, 100b, 100c, and 100d in fig. 3-8, respectively.

As shown in fig. 3 and 4, the intermediate fastener tape 3a of the slide fastener 100a has a tape-like structure, female elements (31a, 32a) are provided on both left and right sides of the axis of the intermediate fastener tape 3a, and male elements (10a, 20a) capable of being used by being inserted into the female elements (31a, 32a) are provided on the inner side edges of the first fastener tape 1a and the second fastener tape 2a, respectively. The female fastener elements (31a, 32a) on both sides are engaged by the intermediate engagement chain band 3 a.

As shown in fig. 5 and 6, the light slide fastener 100b is similar in structure to the light slide fastener 100a described above, with the main difference being that the elements disposed on the intermediate joining stringers 3b are different in structure. The fastener elements disposed on the left and right sides in the transverse direction of the intermediate connecting chain belt 3b are integrally formed to form intermediate fused fastener element bodies 30b, and the front and rear intermediate fused fastener element bodies 30b are arranged at intervals in the axial direction. The intermediate fused fastener element body 30b includes female fastener element heads (310b, 320b) arranged in a horizontal ring shape on both left and right sides and a female fastener body 330b integrally connecting the female fastener element heads (310b, 320 b). The intermediate connecting chain belt 3b is threaded on the middle position of the main chain body 330 b. Thus, the intermediate fused fastener element 30b has a certain lateral extension in the lateral direction and covers the intermediate connecting links 3 b. In the axial direction, the intermediate joining links 3b are exposed between the adjacent two intermediate fused link bodies 30 b. The intermediate fused link body 30b has a relatively large lateral extent and can provide a layout space for a text or pattern layer. The structure of the female fastener element head (310b, 320b) is similar to the head structure of the female fastener element 10 in the above-described slide fastener 100, and a discussion thereof will not be repeated.

On the basis of this solution, the structure of the intermediate connecting fastener tape 3b, such as the intermediate connecting fastener tape 3c in the slide fastener 100c shown in fig. 7, may be further improved, and the intermediate connecting fastener tape 3c is a strip of cloth, a strip of adhesive tape, or a wire in a rope shape.

As shown in fig. 8, the light slide fastener 100d is similar to the light slide fastener 100a described above, and mainly differs in that female elements 31d and male elements 32d are provided on the left and right sides of the axis of the intermediate coupling fastener 3d, respectively, and male elements 10d and female elements 20d capable of being used by being inserted into and engaged with the female elements 31d and male elements 32d are provided on the inner side edges of the first fastener tape 1d and the second fastener tape 2d, respectively. The female element 31d and the male element 32d are engaged by the intermediate engagement chain 3 d.

With reference to fig. 1, in order to reinforce the strength of the left and right ends of the intermediate connecting chain belt 3, a left end guide head 34 and a right end guide head 35 are respectively disposed at the left and right ends of the intermediate connecting chain belt 3. A pair of guide posts (341, 342) is provided on the left end guide head 34.

As shown in fig. 2, the first set of fastener elements and the second set of fastener elements have similar structures, and the structure of the first set of fastener elements will be described as an example. The head of the female chain element 10 is in an open ring shape and is provided with a female chain tooth groove 101 and a female chain tooth groove mouth 102, and the female chain tooth grooves 101 of a plurality of female chain elements 10 which are arranged at intervals in the front-back direction are combined into an axially extending accommodating groove channel; the male element 31 is provided with a male element head 310 which can be received in the female element groove 101. The height H3 of the male coupling head 310 is greater than the height H1 of the female coupling notch 102 and less than the height H2 of the female coupling notch 101. Thus, a certain play is formed between the male element head 310 and the female element groove 101 to reduce the friction between the male element head 310 and the female element groove 101, and the male element head 310 can easily slide from one female element groove 101 to another adjacent female element groove 101 when the male element head 310 is inserted into the female element groove 101 and the intermediate adapter chain belt 3 is axially moved, thereby being axially slid in the receiving groove passage. The male coupling head 310 inserted into the female coupling socket 101 cannot move laterally through the female coupling socket 102 to be separated from the female coupling 10.

The male zipper teeth 31 and the female zipper teeth 10 are sleeved together by adopting a light-sliding sleeve penetrating structure, and the fastening is completed without the extrusion of a pull head, so that the arrangement of the pull head can be omitted, and the influence of the pull head on the light sliding degree of the zipper due to the resistance in the sliding process can be avoided. Therefore, the two adjacent chain belts adopt a light sliding penetrating structure, so that the relative sliding process is particularly easy, and the light sliding feeling is very good. The light slide fastener 100 completely subverts the structure and the sleeving manner of the traditional slide fastener, and gives better application experience to users.

Further, as shown in fig. 9, in order to allow the male element head 310 to be more easily inserted into the female element socket 101, both ends of the male element head 310 in the axial direction are provided with inclined guide surfaces (311, 312), respectively. The inclined guide surfaces (311, 312) may be flat or curved, and when the inclined guide surfaces (311, 312) are curved, the axial cross section of the male element head 310 may have an oblong (commonly called a runway type) structure.

The male fastener element head 310 in this embodiment is preferably formed in an integral structure, and may be separately attached to the fastener tape after being molded by injection molding or the like, or may be formed integrally with the fastener tape.

The slide fastener of the present embodiment may be applied to open or close an opening portion of the fabric 70 such as a bag opening. For example, as shown in fig. 10, is an article of clothing 7 to which a slide fastener is applied. The following description will take the slide fastener 100 as an example.

A pocket 70 is provided on the article of clothing 7, with a first fabric edge 71 and a second fabric edge 72 being reserved on the pocket 70. The first fastener tape 1 of the slide fastener 100 is sewn to the first fabric edge 71, and the second fastener tape 2 is sewn to the second fabric edge 72. In this way, the presence of the intermediate joining chain 3 can appropriately pull the space W between the first chain belt 1 and the second chain belt 2. The larger the spacing W, the easier it is to access the article. The size of the space W can be adjusted by adjusting the transverse width of the middle connecting chain belt 3.

As shown in fig. 10, normally, the first and

second fastener tapes

1 and 2 are equal in length to the first and second fabric edges 71 and 72 of the bag, and the intermediate connecting fastener tape 3 is also substantially equal in length to the first and second fabric edges 71 and 72 in order to close the bag 70, that is, the first and

second fastener tapes

1 and 2 are substantially equal in length to the intermediate connecting fastener tape 3, and the anti-slip device 4 is provided at one axial end (for example, the right end in the drawing) of the first and

second fastener tapes

1 and 2 in order to enable the intermediate connecting fastener tape 3 to slide normally. As shown in fig. 11, the anti-slip device 4 includes an upper connecting bridge 41 and a lower connecting bridge 42 which are vertically separated, a pair of legs of the upper connecting bridge 41 and the lower connecting bridge 42 are connected to the first chain belt 1 and the second chain belt 2, respectively, and a slip passage 40 is provided between the upper connecting bridge 41 and the lower connecting bridge 42. The intermediate engagement chain 3 can pass through the slip path 40.

Meanwhile, as shown in fig. 1, the anti-drop coupler 33 is provided on the intermediate joining chain belt 3, and the anti-drop coupler 33 is higher than the upper connecting bridge 41 and cannot pass through the slide passage 40 so as to prevent the intermediate joining chain belt 3 from completely separating from the first and

second chain belts

1 and 2. The anti-slip device 4 may be configured as a cantilever (with a simple scheme, related views are omitted) connected to the first chain belt 1 or the second chain belt 2, and a free end of the cantilever extends towards the space 6. The anti-drop matching device is a convex stop block which is approximately vertical to the middle and extends upwards to connect the chain belt 3, and the convex stop block is higher than the cantilever. Thus, the intermediate engagement chain 3 can pass through the cantilever, but not through the cantilever.

In this embodiment, in order to facilitate the operation of the intermediate connecting chain belt 3, an operation handle may be provided separately, or the anti-slip fitting device 33 may be used as an operation handle. The operation handle 33 (for convenience of description, the reference numeral of the anti-slip fastener is used hereinafter) may be a braided part extending from both axial ends of the intermediate connecting link 3, or a pull ring threaded on both axial ends of the intermediate connecting link 3. The operation handle 33 is provided at a left side end position of the intermediate joining chain belt 3 in the present embodiment and is arranged between both axial ends of the first chain belt 1 and the second chain belt 2. The operating handle 33 is a plastic handle piece directly injection-molded on the intermediate joining chain belt 3, and the plastic handle piece is vertically arranged perpendicular to the intermediate joining chain belt 3.

In another embodiment, a pair of operation handles 33 may be further provided on the intermediate joining chain belt 3, the pair of operation handles 33 are disposed on both sides of the anti-slip device 4, the intermediate joining chain belt 3 can pass through the slip passage 40, and the operation handles 33 cannot pass through the slip passage 40.

As shown in fig. 1 and 12, in order to prevent the light slide fastener 100 in the closed state from being accidentally disengaged, an engagement stopper 5 is provided at an axial left end position of the first chain belt 1 and the second chain belt 2, the engagement stopper 5 is a connecting seat 5 (for convenience of description, reference numerals of the engagement stopper are used below) connected across between the first chain belt 1 and the second chain belt 2, an elastic clamping opening 52 is provided at a top of the connecting seat 5, a transverse passage 53 adapted to the left end guide head 34 of the intermediate engagement chain belt 3 is provided at a substantially middle position in a thickness direction of the connecting seat 5, and insertion holes (531, 532) adapted to the guide posts (341, 342) are provided at both ends of the transverse passage 53.

In this case, the lever 33 may be provided with an elastic arm 331 that can be engaged in the elastic clip opening 52. When the axial left end portion of the intermediate connecting chain belt 3 moves to the connecting seat 5, the left end guide head 34 partially extends into the transverse passage 53, and the guide posts (341, 342) also partially extend into the insertion holes (531, 532) to allow the elastic arms 331 to be coupled to the elastic clamping openings 52 of the connecting seat 5 so as to stop and position the intermediate connecting chain belt 3. In this way, the intermediate connecting link 3 can be prevented from sliding freely to unzip, but when a proper acting force is applied to pull the intermediate connecting link 3, the elastic arms 331 can be separated from the elastic clip openings 52 again to restore the intermediate connecting link 3 to a free state in which the intermediate connecting link 3 can slide easily between the first link 1 and the second link 2. In this embodiment, the operating handle 33 is a stopper fitting provided on the intermediate connecting link 3, and easily applies a force to the elastic arm 331 to lock the elastic clip 52 and release the elastic clip 52.

It is of course also possible to provide other components on the intermediate adapter link 3, which are different from the operating handle, as stop adapters. For example, the fit between the plug holes (531, 532) and the guide posts (341, 342) is properly adjusted to form an interference fit structure. Thus, the pair of guide posts (341, 342) can be respectively stuck in the pair of insertion holes (531, 532) to stop and position the intermediate engagement chain belt 3. In this case, the pair of guide posts (341, 342) serve as stopper adapters provided on the intermediate connecting link 3, and the elastic arms 331 and the elastic nipples 52 can be omitted. Further, the connecting base 5 may be omitted, and a stopper may be provided at each of left end portions of the first chain belt 1 and the second chain belt 2, so that the insertion holes (531, 532) may be provided at the pair of stoppers, respectively.

In this embodiment, the anti-slip fitting device and the stopper fitting device may be integrated, or the anti-slip fitting device, the stopper fitting device and the operation handle may be integrated as one component, so as to simplify the light-slip zipper structure.

The slide fastener of this embodiment is also applicable to joining two separate fabrics. For example, as shown in fig. 13, is an article of clothing 7a to which a slide fastener is applied. The following description will be made by taking the slide fastener 100a as an example.

The article of clothing 7a includes two separate fabrics, a clothing body 702a and a hat 701 a. The cap 701a is provided with a first fabric edge 71a, and the garment body 702a is provided with a second fabric edge 72 a. The first fastener tape 1a is sewn to the first fabric edge 71a, and the second fastener tape 2a is sewn to the second fabric edge 72 a. And the male tooth and the female tooth in the same suit tooth group are not equal in arrangement length along the axial direction, so that long teeth and short teeth with different lengths are formed. The short chain teeth can slide on the long chain teeth, so that a user wearing the cap 701a can easily drive the cap 701a to slide relative to the clothes main body 702a while twisting his head, and the cap 701a is prevented from blocking the sight. In addition, the light slide type zipper 100a has a double-layer light slide penetrating structure, when the first chain belt 1a and the middle connecting chain belt 3a slide relatively to each other to generate clamping stagnation, the relative sliding between the second chain belt 2a and the middle connecting chain belt 3a is not obviously influenced, so that the clamping stagnation problem generated in the sliding process is greatly relieved, and the light slide type zipper has a light slide hand feeling.

In this embodiment, the long chain teeth may be provided on the first and

second links

1a and 2a, and the short chain teeth are provided on the intermediate transition link 3 a. At this time, the axial length L1 of the first and

second links

1a and 2a is greater than the axial length L2 of the intermediate joining link 3a (see fig. 3). Alternatively, the long chain teeth may be provided on the intermediate joining chain band 3a and the short chain teeth may be provided on the first and

second chain bands

1a and 2a (see fig. 14 and 15). Or the long chain teeth may be provided on one side of the first chain band 1a and the intermediate joining chain band 3a, respectively, and the short chain band is provided on the other side of the second chain band 2a and the intermediate joining chain band 3a (see fig. 16). In addition, the long-chain teeth in the present embodiment may be formed by male tooth arrangement, or may be formed by female tooth arrangement, or the short-chain teeth may be formed.

In order to prevent the short chain teeth from separating from the long chain teeth, the long chain teeth are further provided with a limiting stopper in the embodiment. Specifically, as shown in fig. 3, stoppers (14a, 24a, 15a, 25a) that define the sliding stroke of the intermediate engagement chain 3a are provided at both axial ends of the first and

second chain belts

1a, 2a, respectively. In the drawing, the elements provided on the first fastener tape 1a and the second fastener tape 2a are both male elements, and therefore the stoppers (14a, 24a, 15a, 25a) function to prevent the female elements from passing. At this time, the height of the stoppers (14a, 24a, 15a, 25a) is larger than the height of the female element grooves of the female elements (31a, 32 a). Thus, the intermediate joining chain 3a can slip only between the stoppers (14a, 24a, 15a, 25a) and cannot be separated from the first chain 1a and the second chain 2 a.

In other embodiments, if the long fastener elements are provided on the intermediate joining chain belt 3a, it is only necessary to adjust the stopper correspondingly to the intermediate joining chain belt 3 a. For example, in the slide fastener shown in fig. 14 and 15, both long-chain teeth are provided on the intermediate fastener tape 3a, and therefore stoppers (341a, 342a, 351a, 352a) are provided on the intermediate fastener tape 3a, respectively. Wherein, if long chain tooth is female chain tooth, then the groove passageway is accomodate that female chain tooth groove is constituteed can be sealed to the stopper, prevents public chain tooth head roll-off. For example, the outermost female fastener element is designed to have no female fastener element groove.

In a light slide fastener shown in fig. 16, for example, two long-chain teeth are provided on the first fastener tape 1a and the intermediate fastener tape 3a, respectively, so that stoppers (14a, 15a) are provided at both ends of the first fastener tape 1a, and stoppers (34a, 35a) are provided at both ends of the third fastener tape 3 a.

In other embodiments, it is also possible to provide stoppers only at both axial ends of the first chain belt 1a or the second chain belt 2 a. For example, in fig. 8, stoppers (14d, 15d) are provided only at both ends of the first chain belt 1 d.

To sum up, suit chain tooth group, light slip formula zip fastener and use its goods that this application embodiment disclosed can show the card that improves in the slip process and pause the problem, improve user's body and feel the travelling comfort.
