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 quality and the effect of the product are influenced to a certain extent. In order to improve the light-weight of the slide fastener, many 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 offset element injection-molded slide fastener in chinese patent CN200410030762.2, or a slider, which is improved from the aspect of the structure of the slider, which reduces the friction force with the fastener elements, in chinese patent CN 201620244875.0. 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 inventor finds that the invention patent CN201410658506.1 provides a safe slide chain which can well solve the above problems, and the safe slide chain 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 safety slide chain is not suitable for use in an opening portion of a braid for controlling the opening or closing of the opening portion, and does not substantially function as a conventional slide fastener.

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 present embodiment discloses a slide fastener 100, which can be applied to open or close an opening portion of a fabric 70, such as a pocket. For example, as shown in fig. 1, is an article of clothing 7 that employs a slide fastener.

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 slide fastener 100 shown in fig. 2 and 3 includes 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.

In addition, the light slide fastener 100 further includes a first set of fastener elements disposed between the first fastener tape 1 and the intermediate connecting fastener tape 3, and a second set of fastener elements disposed between the second fastener tape 2 and the intermediate connecting 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. When the intermediate joining chain belt 3 slides in the axial direction relative to the first and

second chain belts

1, 2, the male elements (31, 32) can slide in the axial direction relative to the female elements (10, 20).

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. 1, 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. Meanwhile, the anti-drop fitting 33 is provided on the intermediate joining chain belt 3, and the anti-drop fitting 33 is higher than the upper connecting bridge 41 and cannot pass through the slip passage 40 so as to prevent the intermediate joining chain belt 3 from completely separating from the first chain belt 1 and the second chain belt 2.

As shown in fig. 4, the anti-slip device 4 in this embodiment may include 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.

In addition, the anti-slip device 4 in this embodiment may also be configured to be another structure capable of allowing the intermediate connecting chain belt 3 to pass through, for example, the anti-slip device may also be a cantilever connected to the first chain belt 1 or the second chain belt 2 (the scheme is simpler, and the related view is omitted), and a free end of the cantilever extends toward 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. In this way, the intermediate engagement chain 3 can pass through the cantilever, and the anti-drop dispenser cannot pass 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 33 may be used as an operation handle at the same time (see fig. 2). 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 handle 33e cannot pass through the slip passage 40.

As shown in fig. 2 and 5, 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.

As shown in fig. 2 and 3, 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. 6-9, respectively.

As shown in fig. 6, 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 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. 7, 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. 8, 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. 9, 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. 2, 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 and 3, 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. 10, 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.

In summary, the opening or closing of the opening portion can be conveniently controlled by the light slide type zipper and the product using the light slide type zipper disclosed by the embodiment of the application.

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.
