Description

TECHNICAL FIELD

[0001] The present invention relates to clothing accessories, and more particularly to an easy-slide zipper and articles using the same.

BACKGROUND OF THE INVENTION

[0002] Zippers are commonly used in everyday life and generally includes a left zipper tape that longitudinally extends, a right zipper tape that longitudinally extends and a slider that is longitudinally slidable. By means of slider's movement, teeth on the left zipper tape and the right zipper tape can be meshed together or separated. The existing chain teeth are mostly rigid structures which are integrally formed, such as cold extruded metal teeth or injection molded resin teeth. When the left and right zipper tapes are pulled together, the left chain teeth and the right chain teeth are pressed to be meshed by the slider. A relatively large pressing force is required to mesh the left chain teeth and the right chain teeth together due to fit dimensional accuracy. Moreover, friction occurs between the slider and the chain teeth or tapes when the slider slides. The above various factors will affect the pulling smoothness of the zipper, which affects the hand feeling and the detachment speed of the zipper to some extent when pulling the slider on the zipper. In order to improve the pulling smoothness of the zipper, various solutions have been proposed. For example, Chinese Patent CN 201410348920.2 discloses an elastic meshing zipper with improved chain structure. Chinese Patent CN 200410030762.2 discloses an injection-moulded hook zip fastener with alternative teeth. Chinese Utility Model Patent CN 201620244875.0 discloses a slider with improved slider structure, which reduces the frictional force between slider and chain teeth. However, in the above solutions, the resistance caused by the pressing between the chain teeth and the slider affects the pulling smoothness of the slider. This problem has still not been solved very well.

[0003] To solve the above problem, Chinese Patent CN 201410658506.1 proposes a safety slide chain including an upper chain body and a lower chain body. The upper chain body includes a plurality of clamping rings arranged on a base cloth. Each clamping ring includes two arc-shaped clamping arms which are connected into a whole. The end of the clamping arm is spherical. The lower chain body includes a strip-shaped slide groove and a base cloth connecting seat arranged at the lower end of the slide groove. The slide groove is an inverted trapezoid, and four edges of the slide groove are provided with a rib. The rib at the top end of the slide groove extends out of the outer end of the slide groove and is provided with a stop. The height of the rib on the top end of the slide groove is greater than that of the ribs on other three edges. The base cloth connecting seat is connected to the base cloth. The upper chain body is connected to the lower chain body in such a way that the slide groove is clamped by the clamping rings. This solution omits the arrangement of slider, so that the pressing of the slider to the chain teeth can be completely avoided. This invention discloses a single-layer easy-slide fit consisting of a clamping ring and a rib. However, the slide chain easily gets stuck between the clamping ring and the slide groove when in use, especially when the slide chain is applied to the article with a ring structure because the clamping ring must move along the ring.

DETAILED DESCRIPTION OF EMBODIMENTS

[0024] The technical solutions of the present application will be clearly and completely described in the following with reference to the embodiments and drawings. Obviously, these embodiments are only a part of the implementations of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments without creative efforts fall within the scope of the present application.

[0025] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] In an embodiment, an easy-slide zipper 100a for connecting two separate fabrics is illustrated. For example, an article of clothing 7a using the easy-slide zipper 100a is shown in FIG. 1.

[0027] The article 7a includes two separate fabrics, a garment body 702a and a hood 701a. A first fabric edge 71a is reserved on the hood 701a, and a second fabric edge 72a is reserved on the garment body 702a.

[0028] The easy-slide zipper 100a includes a first tape 1a, a second tape 2a and at least one joining tape 3a. Referring to FIG. 2, one joining tape 3a is shown. FIG. 15 shows two joining tapes 3a1 and 3a2. The joining tape 3a may be in the form of a strip, for example a strip with a width of, for example 10 cm or 15 cm. There is a space 6a between the first tape 1a and the second tape 2a, and the joining tape 3a is arranged in the space 6a. Each tape extends in a longitudinal direction, and all of the tapes are spaced apart in a transverse direction perpendicular to the longitudinal direction. The first tape 1a and the second tape 2a are respectively arranged on both side edges of the joining tape 3a in a transverse direction. Chain sets are arranged between two adjacent tapes.

[0029] As exemplarily shown in FIG. 2, a first chain set 4a and a second chain set 4b are illustrated. The first chain set 4a is arranged between the first tape 1a and the joining tape 3a, and the second chain set 4b is arranged between the second tape 2a and the joining tape 3a. Each of the first chain set 4a and the second chain set 4b includes male teeth (10a, 20a) and female teeth (31a, 32a) which mesh with each other. The female teeth (31a, 32a) are respectively arranged on the left and right sides of the joining tape 3a in a transverse direction (perpendicular to the longitudinal direction). The male teeth 10a are arranged on an inner side of the first tape 1a. The male teeth 20a are arranged on an inner side of the second tape 2a. When the first tape 1a and the joining tape 3a move relative to each other in a longitudinal direction, the male teeth 10a can slide longitudinally relative to the female teeth 31a. When the second tape 2a and the joining tape 3a move relative to each other in a longitudinal direction, the male teeth 20a can slide longitudinally relative to the female teeth 32a.

[0030] As shown in FIGS. 2 and 3, the female teeth (31a, 32a) arranged on the left and right sides of the joining tape 3a in a transverse direction are spaced apart in the transverse direction rather than integrally formed. Thus, the joining tape 3a can be exposed between the female teeth (31a, 32a) at the left and right sides of the joining tape 3a in the transverse direction. The joining tape 3a provides a space for arrangement where decorative elements such as characters and patterns may be provided. The joining tape 3a becomes a sliding decorative tape between the first tape 1a and the second tape 2a after being provided with the characters or patterns, thereby adding the aesthetic beauty of the zipper.

[0031] In some embodiments, the male teeth and female teeth may be interchangeable, as described in detail below. For the purpose of distinction, different easy-slide zippers are labeled as 100b, 100c, 100d and 100e, respectively, as shown in FIGS. 4-8.

[0032] As shown in FIGS. 4 and 5, the easy-slide zipper 100b is similar in structure to the easy-slide zipper 100a, where the key difference is that the structure of the male teeth and/or female teeth arranged on the joining tape 3b are different from that of the easy-slide zipper 100a. A pair of male tooth and female tooth or a pair of male teeth or a pair of female teeth arranged on the left and right sides of the joining tape 3b in the transverse direction is integrally formed to form a joining tooth body 30b. A front and rear joining tooth bodies 30b are arranged apart in a longitudinal direction. The joining tooth body 30b includes a female tooth head (310b, 320b) arranged on the left and right sides in a transverse direction, and a female tooth body 330b connecting the female tooth heads (310b, 320b). The joining tape 3b is sleeved in the middle of the female tooth body 330b. In this way, the joining tooth body 30b extends to a distance along a transverse direction and covers the joining tape 3b. In the longitudinal direction, the joining tape 3b is exposed between the two adjacent joining tooth bodies 30b. The joining tooth body 30b has a relatively large width to provide a large space for the arrangement og characters or patterns.

[0033] The joining tape 3b may be improved based on the embodiment, for example, a joining tape 3c of the easy-slide zipper 100c shown in FIG. 6. The joining tape 3c is a rope-like cloth strip, plastic strip or wire.

[0034] As shown in FIG. 7, a easy-slide zipper 100d is similar in structure to that of the easy-slide zipper 100a, where the key difference is that female teeth 31d and male teeth 32d are respectively arranged on the left and right sides in a longitudinal direction along the joining tape 3d. The male teeth 10d and the female teeth 20d respectively meshed with the female teeth 31d and the male teeth 32d are arranged on the inner sides of the first tape 1d and the second tape 2d respectively. The female teeth 31d and the male teeth 32d are connected by the joining tape 3d.

[0035] As shown in FIG. 8, a easy-slide zipper 100e is similar in structure to that of the easy-slide zipper 100a, where the key difference is that the female teeth (10e, 20e) are arranged on the left and right sides of the joining tape 3e in a longitudinal direction. The male teeth (31e, 32e) meshing with the female teeth (10e, 20e) are arranged on the inner sides of the first tape 1e and the second tape 2e respectively. The male teeth (31e, 32e) on both sides are connected by the joining tape 3e.

[0036] It is further described with the following easy-slide zipper 100a as an example. Referring to FIG. 1, the first tape 1a is sewn to a first fabric edge 71a, and the second tape 2a is sewn to the second fabric edge 72a. Moreover, the male teeth and female teeth in the same chain set are arranged in different length in the longitudinal direction to form the first chains 5a and the second chains 5b. The length of the first chains 5a is greater than that of the second chains 5b. The second chains 5b can slide on the first chains 5a, so that the user wearing the hood 701a enables the sliding movement of the hood 701a relative to the garment body 702a while preventing the hood 701a from hindering the vision. In addition, the easy-slide zipper 100a has a double-layer easy-slide sleeve structure. When the first tape 1a get stuck during sliding relative to the joining tape 3a, the sliding of the second tape 2a relative to the joining tape 3a is not significantly affected. The stuck problem during sliding is greatly alleviated, such that a more smooth feeling is achieved.

[0037] In the present embodiment, the first chain 5a may be arranged on the first tape 1a and the second tape 2a, and the second chain 5b is arranged on the joining tape 3a. At this time, a longitudinal length L1 of the first tape 1a and the second tape 2a is greater than a longitudinal length L2 of the joining tape 3a (see FIG. 2). Alternatively, the first chain 5a may be arranged on the joining tape 3a, and the second chain 5b is arranged on the first tape 1a and the second tape 2a (see FIG. 9 and 10). Alternatively, the first chain 5a may be arranged on one side of the first tape 1a and the joining tape 3a respectively, and the second chain 5b is arranged on the other side of the second tape 2a and the joining tape 3a (see FIG. 11). Further, the first chain 5a in the present embodiment may be formed by the male teeth or female teeth. The second chain 5b may be similar to the first chain 5a.

[0038] In order to prevent the second chain 5b from disengaging from the first chain 5a, the embodiment further provides a stop on the first chain 5a. Specifically, as shown in FIG. 2, stops (14a, 24a, 15a, 25a) defining the sliding stroke of the joining tape 3a are respectively arranged at both longitudinal ends of the first tape 1a and the second tape 2a. In FIG. 2, the first tape 1a and the second tape 2a are both provided with the male teeth, so that the stops (14a, 24a, 15a, 25a) are configured to prevent the passage of the female teeth. At this time, the height of the stop (14a, 24a, 15a, 25a) is greater than that of a female tooth socket of the female teeth (31a, 32a). Thus, the joining tape 3a can only slide between the stops (14a, 24a, 15a, 25a) and will not disengage from the first tape 1a and the second tape 2a.

[0039] In some embodiments, if the first chain 5a is arranged on the joining tape 3a, it is only necessary to adjust the stop to the joining tape 3a. For example, the easy-slide zipper shown in FIGS. 9 and 10 has two first chains 5a arranged on the joining tape 3a, so that stops (341a, 342a, 351a, 352a) are arranged on the joining tape 3a respectively. If the first chain 5a consists of female teeth, the stop may close a holding channel formed by the female tooth socket to prevent the male teeth from disengagement. For example, as shown in FIG. 8, the easy-slide zipper has two first chains 5a arranged on the first tape 1e and the second tape 2e. The two first chains 5a are both formed by the female teeth. The outermost female teeth of the first tape 1e and the second tape 2e are designed to have stops (14e, 15e, 24e, 25e) without the female tooth socket.

[0040] For example, referring to FIG. 11 again, the two first chains 5a are respectively arranged on the first tape 1a and the joining tape 3a, so that two stops (14a, 15a) are provided at both ends of the first tape 1a, and other two stops (34a, 35a) are provided at both ends of the third joining tape 3a.

[0041] In some embodiments, it is possible to provide stops only at both longitudinal ends of the first tape 1a or the second tape 2a. For example, in FIG. 7, stops (14d, 15d) are provided only at both ends of the first tape 1d.

[0042] In some other embodiments, limiting structures may be formed at ends of the first chain 5a by, for example sewing, thereby achieving the same limiting effect as the stops.

[0043] In the chain sets of the present embodiment, the male and female teeth can adopt various feasible sliding meshing mechanisms as long as the male and female teeth can slide relative to each other.

[0044] As shown in FIG. 12, the first chain set 4a and the second chain set 4b have similar structures. The structure of the first chain set 4a will be described below as an example. A head of the female teeth 31a in an open ring shape has a female tooth socket 311 a and a socket opening 312a. A plurality of female tooth sockets 311a of the female teeth 31a arranged apart are combined to form the holding channel that extends longitudinally. The male teeth 10a is provided with a male tooth head 100a that is accommodated in the female tooth socket 311a. The height H3 of the male tooth head 100a is greater than the height H1 of the socket opening 312a and smaller than the height H2 of the female tooth socket 311a. Thus, a movable gap is formed between the male tooth head 100a and the female tooth socket 311a to reduce the friction between the male tooth head 100a and the female tooth socket 311 a. The male tooth head 100a is inserted into the female tooth socket 311 a. When the joining tape 3a longitudinally moves, the male tooth head 100a can easily slide from one female tooth socket 311a to an adjacent female tooth socket 311a so as to longitudinally slide in the holding channel. However, the male tooth head 100a inserted into the female tooth socket 311a cannot transversely move through the socket opening 312a to disengage from the female teeth 31a.

[0045] The male teeth 10a and the female teeth 31a are fitted together via an easy-slide sleeve structure. Pressing from a slider is not required to complete the fastening, so that the arrangement of the slider can be omitted, thereby avoiding the sliding resistance during sliding to affect the smoothness of the zipper. It can be seen that the easy-slide sleeve structure between the two adjacent tapes makes it particularly easy during relative movement, leading to a very good easy-slide feeling. The easy-slide zipper 100 completely changes the structure and fitting manner of the traditional zipper, providing the user a better experience.

[0046] In the present embodiment, the first tape 1a and the second tape 2a are directly connected to the clothes. In order to provide a better flexibility, the first tape 1a and the second tape 2a are preferably provided with male teeth (10a, 20a) with small size, and the joining tape 3a is provided with the female teeth (31a, 32a). In addition, since the female teeth (31a, 32a) are large in size and complicated in structure, the bending flexibility is not good. In a preferred embodiment, the male teeth (10a, 20a) are used as the first chain, and the female teeth (31a, 32a) are used as the second chain.

[0047] As shown in FIG. 13, in order to improve the flexibility of the joining tape 3a, the joining tape 3a may be divided into a plurality of sub-sections 30a sliding independently relative to each other, thereby improving the local bending flexibility of the joining tape 3a.

[0048] Further, as shown in FIG. 14, in order to allow the male tooth head 100a to be inserted into the female tooth socket 311a more easily, the opposite ends of the male tooth head 100a in a longitudinal direction are respectively provided with inclined guiding faces (101a, 102a). The inclined guiding faces (101a, 102a) may be flat or curved. When the inclined guiding faces (101a, 102a) are curved, the male tooth head 100a when viewed in a transverse direction may be substantially elliptic (known as a racetrack shape).

[0049] In a preferred embodiment, the male tooth head 100a is an integrated structure, which can be formed by injection molding or the like and then attached to the tape, or may be integrally formed with the tape.

[0050] In summary, the easy-slide zipper and articles using the same disclosed in the embodiments of the present application can significantly alleviate the stuck problem in the sliding process.

[0051] Differences between the various embodiments are described in the above embodiments of the present application. Various optimal features of the embodiments may be combined to form a preferred embodiment.

[0052] The embodiments are only illustrative of the present application, and are not intended to limit the application. It should be understood that for those of ordinary skills in the art, improvements or variations can be made based on the above descriptions, and such improvements and variations fall within the scope of the appended claims.
