Description

Light slide type zipper and product using same

Technical Field

The application relates to the field of clothing accessories, in particular to a light slide type zipper and a product applying the same.

Background

Slide fasteners are common in everyday life and generally comprise an axially extending left fastener tape, a right fastener tape and an axially sliding slider, by means of which the teeth on the left and right fastener tapes can be engaged with or disengaged from each other. Most of the existing fastener elements are integrally formed rigid structures, such as metal fastener elements formed by cold extrusion or resin fastener elements formed by injection molding, and in the process of pulling the left fastener tape and the right fastener tape together, the left fastener element of the left fastener tape and the right fastener element on the right fastener tape are extruded by the pull head to be matched and meshed together in a concave-convex mode. The left and right coupling elements require a relatively large pressing force to be engaged due to the influence of the associated fitting dimensional accuracy. And the slider can generate certain friction force with the zipper teeth or the cloth belt in the sliding process. The existence of the factors can influence the sliding degree of the zipper, and the hand feeling and the separating speed of the zipper when the zipper puller is pulled are influenced to a certain extent. In order to improve the light-weight of the slide fastener, various solutions have been proposed, such as an elastic engagement slide fastener in chinese patent CN201410348920.2, which is improved from the aspect of the structure of the fastener elements, a hook-shaped dislocated element injection-molded slide fastener in chinese patent CN200410030762.2, or a slider, which reduces the friction force with the fastener elements, in chinese patent CN201620244875.0, which is improved from the aspect of the structure of the slider, and so on. However, in the above-mentioned solutions, the problem that the resistance generated by the mutual squeezing between the fastener element and the slider affects the lightness is still not solved well.

The chinese invention patent CN201410658506.1 proposes a safe slide chain which can solve the above problems well, and comprises an upper chain body and a lower chain body. The chain body is including setting up a plurality of centre gripping rings on the base cloth, the centre gripping ring includes two arc centre gripping arms of connecting as an organic whole, the tip of centre gripping arm is spherical. The lower chain body comprises a long-strip-shaped sliding groove and a base cloth connecting seat arranged at the lower end of the sliding groove, the sliding groove is an inverted trapezoidal sliding groove, protruding ribs are arranged on four edges of the sliding groove, the protruding ribs on the top end of the sliding groove extend out of the outer end of the sliding groove and are provided with limiting tables, the protruding height of the protruding ribs on the top end of the sliding groove is larger than the protruding height of the protruding ribs on the other three edges, the base cloth connecting seat is connected with base cloth, and the upper chain body is clamped on the protruding ribs of the sliding groove through the clamping rings and is connected with the lower chain body. The scheme completely omits the arrangement of the pull head, so that the extrusion friction of the pull head on the zipper teeth can be completely avoided. The chinese patent 201410658506.1 proposes a single-layer sliding sleeve method consisting of a clamping ring and a rib, but the sliding chain is very easy to be stuck between the clamping ring and the sliding groove when in use, and particularly when applied to products with a ring structure, the clamping ring must move in a ring shape, and is very easy to be stuck.

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 application discloses a light slide fastener 100a, and the light slide fastener 100a in the embodiment can be applied to connecting two independent fabrics. For example, as shown in fig. 1, is an article of clothing 7a to which a slide fastener is applied.

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 slide fastener 100a includes a first fastener tape 1a, a second fastener tape 2a, and an intermediate joining fastener tape 3 a. Wherein the number of the intermediate joining links 3a is one or more. Referring to FIG. 2, one intermediate joining strand 3a is included, and referring to FIG. 15, two intermediate joining strands 3a1 and 3a2 are included. The intermediate joining links 3a may be in a band shape, for example, a tape having a certain width, for example, 10cm, 15 cm. The first and

second links

1a and 2a have a space 6a therebetween, and the intermediate joining link 3a is disposed in the space 6 a. 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. The first chain belt 1a and the second chain belt 2a are respectively located at one side edge of the arrangement direction. A set of chain teeth is arranged between two adjacent chain belts.

Still taking fig. 2 as an example, it includes a first set of set fastener elements disposed between the first fastener belt 1a and the intermediate joining fastener belt 3a, and a second set of set fastener elements disposed between the second fastener belt 2a and the intermediate joining fastener belt 3 a; the first suit tooth group and the second suit tooth group respectively comprise male tooth elements (10a, 20a) and female tooth elements (31a, 32a) which can be used in a threading and matching mode. The female elements (31a, 32a) are disposed on the left and right sides of the intermediate connecting link 3a in the transverse direction (perpendicular to the axial direction), the male element 10a is disposed on the inner side of the first link 1a, and the male element 20a is disposed on the inner side of the second link 2 a. When the first chain belt 1a and the intermediate joining chain belt 3a relatively move in the axial direction, the male element 10a can slide in the axial direction relative to the female element 31 a; when the second chain belt 2a and the intermediate joining chain belt 3a are relatively moved in the axial direction, the male element 20a can slide in the axial direction relative to the female element 32 a.

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

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

100b, 100c, 100d, and 100e in fig. 4-8, respectively.

As shown in fig. 4 and 5, 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 30b includes female fastener element heads (310b, 320b) disposed laterally on the 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.

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. 6, 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. 7, 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.

As shown in fig. 8, the light slide fastener 100e is similar to the light slide fastener 100a described above, and mainly differs in that male elements (31e, 32e) are provided on left and right sides of an axis of the intermediate connecting link 3e, and male elements (31e, 32e) capable of being used by being inserted into the female elements (10e, 20e) are provided on inner sides of the first link 1e and the second link 2e, respectively. The male elements (31e, 32e) on both sides are engaged by the intermediate engagement chain band 3 e.

The following description will proceed with the example of the slide fastener 100 a. Referring to fig. 1, the first chain belt 1a is sewn on the first fabric edge 71a, and the second chain belt 2a is sewn on 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. 2). 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. 9 and 10). 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. 11). 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. 2, 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 chain belt 1a and the second chain belt 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. 9 and 10, both long-chain teeth are provided on the intermediate joining fastener tape 3a, and therefore stoppers (341a, 342a, 351a, 352a) are provided on the intermediate joining 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, in the light slide fastener shown in fig. 8, long chain teeth are disposed on the first fastener tape 1e and the second fastener tape 2e and are formed by arranging female fastener elements, and the female fastener elements at the outermost ends of the first fastener tape 1e and the second fastener tape 2e are designed to form stoppers (14e, 15e, 24e, 25e) in a structure without female fastener element grooves.

In a light slide fastener shown in fig. 11, 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. 7, stoppers (14d, 15d) are provided only at both ends of the first chain belt 1 d.

In other embodiments, a limiting structure can be formed at the end part of the long chain tooth through processes such as sewing and the like, so that the same limiting effect as that of the limiting device is achieved.

In the set of fastener elements in this embodiment, the male fastener element and the female fastener element may adopt various possible sliding fit mechanisms as long as they can slide relative to each other.

As shown in fig. 12, 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 element 31a is open ring-shaped and has a female element slot 311a and a female element slot 312a, and the female element slots 311a of several female elements 31a arranged at intervals in the front-back direction are combined into an axially extending accommodating slot channel; the male element 10a is provided with a male element head 100a which can be received in the female element groove 311 a. The height H3 of the male coupling element head 100a is greater than the height H1 of the female coupling element notch 312a and less than the height H2 of the female coupling element notch 311 a. Thus, a certain play is formed between the male element 100a and the female element recess 311a to reduce the frictional force between the male element 100a and the inside of the female element recess 311a, and when the male element 100a is inserted into the female element recess 311a and the intermediate connecting link belt 3a is moved axially, the male element 100a can easily slide from one female element recess 311a into the other adjacent female element recess 311a, thereby being able to slide axially in the receiving recess passage. The male element head 100a inserted into the female element groove 311a cannot move laterally through the female element notch 312a to be disengaged from the female element 31 a.

The male zipper teeth 10a and the female zipper teeth 31a are sleeved together by adopting a light-sliding sleeving structure, and the fastening is completed without the extrusion of the pull head, so that the arrangement of the pull head can be omitted, and the influence of the resistance of the pull head on the light sliding degree of the zipper 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.

In this embodiment, since the first and

second fastener tapes

1a and 2a are directly connected to the clothes, in order to have a good flexibility, male coupling elements (10a and 20a) having a small volume are preferably provided on the first and

second fastener tapes

1a and 2a, and female coupling elements (31a and 32a) are preferably provided on the intermediate fastener tape 3 a. In addition, the female elements (31a, 32a) are bulky and complicated in structure, and therefore, poor in flexibility in bending. In this case, the present embodiment recommends using male elements (10a, 20a) as long elements and female elements (31a, 32a) as short elements.

As shown in fig. 13, in order to improve the flexibility of the intermediate joining chain band 3a, the intermediate joining chain band 3a may be divided into a plurality of sub-segments 30a, and the plurality of sub-segments 30a may be independently slid therebetween, thereby improving the local bending flexibility.

Further, as shown in fig. 14, in order to allow the male element head 100a to be more easily inserted into the female element groove 311a, both ends of the male element head 100a in the axial direction are provided with inclined guide surfaces (101a, 102a), respectively. The inclined guide surfaces (101a, 102a) may be flat or curved, and when the inclined guide surfaces (101a, 102a) are curved, the lateral view of the male element head 100a may have an oblong (commonly known as a racetrack) configuration.

The male element head 100a 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.

In summary, the light slide fastener and the product using the same disclosed in the embodiments of the present application can significantly improve the problem of clamping stagnation during the sliding process.

In the embodiments of the present application, the difference between the embodiments is described in detail, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
