Description

Technical Field

[0001] This application claims the priority of a Chinese patent application with an application number of 202221984342.8 and a utility model title of "Slide Fastener and Garment", which was filed with the China National Intellectual Property Administration on July 29, 2022, and all its contents are incorporated herein by reference.

[0002] This application relates to the technical field of clothing accessories and clothing, and particularly relates to slide fasteners and clothing.

Background Art

[0003] A slide fastener generally includes a main member unit and a sub-member unit, and realizes the relative sliding between the main member and the sub-member by continuously arranged elements. Currently, it is widely applied to clothes, packaging, pockets, tents, etc. Generally, the sub-teeth of the sub-member unit slide on the main-teeth of the main member unit. For example, when used at the connection position between a garment and a hat, one unit is connected to the garment and the other unit is connected to the hat, so that the hat can be easily rotated along with the head.

[0004] For example, Chinese Patent Application (Publication No.: CN114468483A) discloses a slide fastener, which realizes smooth sliding through the engagement of the shape structures of the main member unit, the sub-member unit, the main teeth of the main member and the sub-teeth of the sub-member. However, when using this type of slide fastener, in order to ensure an excellent sliding effect, the main member unit or the sub-member unit is exposed, and the main teeth of the main member unit and the sub-member unit are attached with a gap between them, so air leakage and water leakage are likely to occur, which seriously affects the aesthetic effect of the clothing.

[0005] In order to develop good sales channels in the market, the clothing arranges an edge for shielding on the hat. As a result, when the hat rotates, the edge rotates along with the hat and rubs against the outer surface of the main member teeth. Therefore, when the sub-member teeth and the main member teeth themselves have frictional force, the external frictional force is increased, and when turning around, the smoothness of the slide fastener is reduced, noise is likely to occur, and the hat is close to the ear. Moreover, since it is located in the blocking path of the hat, clothes and the edge, it is not comfortable when the wearer turns around.

Summary of the Invention

Problems to be Solved by the Invention

[0023] Hereinafter, the embodiments of this application will be described in more detail in conjunction with the drawings.

[0024] A slide fastener, comprising a main member unit 100 having a main member tape 110, and a plurality of working teeth cavities 130 and a main slide portion 140 that are provided at intervals on the main member tape 110 and form a slide rail, and a sub-member unit 200 having a sub-member tape 210 and sub-member working teeth 220 provided at intervals on the sub-member tape 210, that is, the main member unit 100 and the sub-member unit 200 are slidably connected, and the plurality of main member working teeth 120 are provided on the main member tape 110 so as to be in sequence to form a sliding rail, the main member unit 100 further includes the working teeth cavities 130 and the main slide portion 140 of the main member working teeth 120, and the plurality of working teeth cavities 130 and the main slide portion 140 are engaged in sequence to form a slide rail, the sub-member working teeth 220 are arranged and provided on the sub-member tape 210 so as to be in sequence, one end of the sub-member working teeth 220 slides on the slide rail, and the other end is connected to the sub-member tape 210, whereby it is sewn onto clothing.

[0025] The main member working tooth 120 includes a main member base 121 and a tooth arm member 122. The main member base 121 is connected to the main member tape 110. The tooth arm members 122 are provided at both ends of the main member base 121. The tooth arm members 122 include a base portion 122a and an arm portion 122b that are connected to each other. The base portion 122a is connected to the main member base 121. The arm portion 122b of one end tooth arm member 122 forms a working tooth cavity 130 and a main slide portion 140 so as to extend to the other end tooth arm member 122. Specifically, as shown in FIG. 2, the tooth arm members 122 are provided on the upper side of the main member base 121. The main member base 121 and the tooth arm members 122 are integrally formed. The front side and the rear side of the main member base 121 are connected to the main member tape 110. The tooth arm members 122 include a base portion 122a connected to the main member base 121 and an arm portion 122b above the base portion 122a. The base portion 122a is connected to the front end of the main member base 121. The arm portion 122b is connected to the base portion 122a and extends to the rear end of the main member base 121. Further, a working tooth cavity 130 and a main slide portion 140 are formed between the arm portion 122b and the main member base 121.

[0026] As shown in FIG. 2, among the front end and the rear end on the upper side of the main member base 121, the arm portion 122b at the front end extends to the rear end, and the arm portion 122b at the rear end extends forward. Thus, the tooth arm members 122 at both ends of the main member base 121 form an enclosure, and the entire main member base 121 is symmetric. The notch placed between the arm portions 122b is the main slide portion 140. What is formed so as to be surrounded by the tooth arm members 122 and the main member base 121 is the working tooth cavity 130. Here, the plane of the main slide portion 140 facing the direction of the working tooth cavity 130 and the main member tape 110 form a certain angle, and most preferably, it is perpendicular to the plane where the main member tape 110 is located.

[0027] When the direction towards the cavity 130 of the main slide part 140 is perpendicular to the plane where the main member tape 110 is located, after the main member tape 110 is sewn onto the clothing, the opening of the main slide part 140 can be guaranteed to be horizontal. That is, at this time, the connecting part 222 is horizontal. The prior art, for example, the Chinese patent application (publication number: CN114468483A) discloses a slide fastener. By using the connecting part 222 as an alternative to the conventional slide fastener form, the technical problem of the large frictional force at the connecting position of the conventional main slide part 140 is solved. Therefore, through the cooperation between the connecting part 222 and the main slide part 140, an excellent sliding effect can be achieved. However, in this embodiment, the sub-member unit 200 is connected to the hat. After putting on the hat, the sub-member unit 200 (specifically, the tooth part 223 of the sub-member cavity 220) applies a force towards the hat (upward when worn) to the main-member cavity 120. Therefore, the tooth part 223 simultaneously rubs against the main slide part 140 and the side of the main-member cavity 120 (including the side wall surface of the main slide part 140). In contrast, in the present technical solution, when the sub-member cavity 220 receives an upward force, through the cooperation between the connecting part 222 and the main slide part 140, the tooth part 223 does not rub against the main slide part 140, and the friction between the tooth part 223 and the main-member cavity 120 on the side wall surface of the main slide part 140 can be reduced. Therefore, only the tooth part 223 and the side of the main-member cavity 120 (since there is a distance between the main-member cavities 120) rub against each other, further improving the smoothness of the fastener.

[0028] The sub-member working tooth 220 includes a tooth portion 223, a connecting portion 222, and a sub-member base 221. The sub-member base 221 is connected to the sub-member tape 210. The tooth portion 223 is fitted into the working tooth cavity 130, and the connecting portion 222 is fitted into the main slide portion 140. The tooth portions 223 slide along the sequentially arranged working tooth cavities 130, and the sub-member base 221 covers the side surface of the arm portion 122b on the side of the main slide portion 140. That is, the sub-member working tooth 220 includes a sub-member base 221, a connecting portion 222, and a tooth portion 223. The tooth portion 223 slides in the working tooth cavity 130. By making the cross-section of the tooth portion 223 larger than that of the main slide portion 140, it is ensured that the sub-member working tooth 220 does not directly detach from the main-member working tooth 120. The connecting portion 222 slides in the main slide portion 140, and the sub-member base 221 is connected to the sub-member tape 210.

[0029] Specifically, as shown in FIG. 10, the sub-member working tooth 220 includes a sub-member base 221, a connecting portion 222, and a tooth portion 223. Both the upper and lower sides of the sub-member base 221 are connected to the sub-member tape 210. The connecting portion 222 is perpendicular to the sub-member base 221. The sub-member base 221, the connecting portion 222, and the tooth portion 223 are arranged in an "I" shape. The connecting portion 222 slides in the main slide portion 140, and its size is adapted to the main slide portion 140. Here, the sub-member base 221 extends vertically and shields the right side surface of the main-member working tooth 120. That is, the left side surface of the sub-member base 221 is slidably connected to the right side surface of the main-member working tooth 120. Connected to the sub-member base 221 on the right side surface of the main-member working tooth 120, the sub-member base 221, instead of the edge of the fabric, rubs against the main-member working tooth 120, thereby greatly reducing the total frictional force, effectively improving the overall smoothness, and reducing the frictional noise.

[0030] Also, in other embodiments, the direction of the main slide portion 140 towards the main-member base 121 is perpendicular to the plane where the main-member tape 110 is located, and arc-shaped surfaces are formed on both adjacent surfaces of the sub-member base 221 and the main-member base 121.

[0031] As shown in FIG. 10, both the upper and lower sides of the main member working tooth 120 are connected to the main member tape 110. The main slide portion 140 extends in the direction of the working tooth cavity 130, and the extension line thereof is perpendicular to the plane where the main member tape 110 is located. Furthermore, the main member working tooth 120 arranged vertically is formed, and the opening of the main slide portion 140 is in the horizontal direction. Both the upper and lower sides of the sub-member base 221 are connected to the sub-member tape 210. The main member tape 110 is parallel to the sub-member tape 210. On the right side surface of the main member working tooth 120, a gradually shifting folded surface or arc-shaped surface is formed, and a small contact surface is formed at the rightmost side of the main member working tooth 120. An arc-shaped surface is formed on the left side of the sub-member base 221, and the middle position of the arc-shaped surface is a protruding position. Furthermore, the contact surface between the main member working tooth 120 and the sub-member base 221 is reduced.

[0032] In such a connection form, the sub-member tape 210 is directly connected to the cap. Since the lower edge of the cap forms the edge in the prior art, there is no need to separately add an edge for shielding the main member working tooth 120. On the premise of realizing an excellent visual effect, there is no air leakage or water leakage, and the sealing performance is better.

[0033] Also, in another embodiment, a wing portion 220a is formed on the sub-member base 221, and the wing portion 220a extends in the extending direction of the main member working tooth 120. Specifically, as shown in FIG. 10, wing portions 220a are formed on the sub-member base 221 in the up and down directions. Thereby, the overall vertical length of the sub-member base 221 basically coincides with the main member base 121. Furthermore, the sub-member base 221 can entirely surround the opening end of the main slide portion 140 of the main member working tooth 120 and can exhibit an excellent sliding effect.

[0034] In another embodiment, the tooth arm members 122 at both ends of the main member base 121 are symmetrically arranged with respect to each other. Specifically, as shown in FIG. 10, the central axis of the duty tooth cavity 130 and the main slide portion 140 coincides with the central axis of the main member duty tooth 120. As a result, the connection portion 222 is always in the horizontal direction, and when the cap moves, the tooth portion 223 and the connection portion 222 are moved.

[0035] In another embodiment, it further includes a position-limiting duty tooth 410. The position-limiting duty tooth 410 is provided at the tip of the sub-member duty tooth 220 and is arranged at intervals. A convex portion 420 is provided at one end of the position-limiting duty tooth 410, thereby reducing the contact area between the sub-member duty tooth 220 adjacent to the position-limiting duty tooth 410 and the main member duty tooth 120.

[0036] A first position-limiting member 300 is further connected to the main member tape 110. The first position-limiting member 300 is provided at the tip of the main member duty tooth 120 at intervals, so that the main member duty tooth 120 forms a slide rail. Also, the first position-limiting members 300 at both ends of the slide rail limit the sub-member duty tooth 220, thereby preventing the sub-member unit 200 from detaching from the main member unit 100.

[0037] It includes one or more second position-limiting members 400. The second position-limiting members 400 are provided at the tip of the sub-member duty tooth 220 at intervals. That is, in the queue of the sub-member duty tooth 220 in one row, there are sub-member duty teeth 220 on both the left and right sides of at least two second position-limiting members 400. The second position-limiting members 400 are connected to the sub-member tape 210, and the sub-member tape 210 moves the sub-member duty tooth 220 and the second position-limiting members 400 together.

[0038] Due to the engagement action between the first position limiting member 300 and the second position limiting member 400, the sub-member unit 200 slides on the slide rail formed by the main member working teeth 120 between the two first position limiting members 300. When the sub-member unit 200 slides to the first position, the first position limiting member 300 abuts against the second position limiting member 400. As a result, the sliding of the sub-member unit 200 is restricted. When in the first position, the sub-member working teeth 220 on one side of the second position limiting member 400 are located within the slide rail, and the sub-member working teeth 220 on the other side of the second position limiting member 400 are located outside the slide rail. When in the second position, the sub-member working teeth 220 on one side of the other second position limiting member 400 are located within the slide rail, and the sub-member working teeth 220 on the other side are located outside the slide rail.

[0039] As shown in FIG. 1, the main member unit 100 includes main member working teeth 120 and two main member tapes 110. In the left-right direction, a plurality of main member working teeth 120 are provided between the two main member tapes 110 so as to form a row of queues. A certain pitch is set between every two main member working teeth 120. The edge of the main member tape 110 forms a rib 111, and the main member working teeth 120 are provided on the rib 111. Since the connection structure has already been disclosed in the application with the publication number CN215958629U, it will not be elaborated here. In other embodiments, it may further include at least one main member tape 110, and the main member working teeth 120 are connected to one main member tape 110.

[0040] As shown in FIG. 2, the front and rear sides of each main member working tooth 120 are connected to the main member tape 110. The working tooth cavity 130 penetrates the main member working tooth 120 in the left-right direction. The main slide portion 140 extends upward from the working tooth cavity 130 and penetrates the main member working tooth 120. The diameter of the main slide portion 140 is smaller than that of the working tooth cavity 130, exerting a position-limiting effect. Referring to FIG. 1, a plurality of main member working teeth 120 arranged in sequence, that is, a plurality of working tooth cavities 130 and main slide portions 140 arranged in sequence form a slide rail in the left-right direction, thereby being used for the sub-member working tooth 220 to slide.

[0041] As shown in FIG. 3, the sub-member unit 200 includes sub-member working teeth 220 and two sub-member tapes 210. In the left-right direction, a plurality of sub-member working teeth 220 are provided between the two sub-member tapes 210 so as to form a single row of queue. A certain pitch is provided between every two sub-member working teeth 220. The edge of the sub-member tape 210 forms a rib 111, and the sub-member working teeth 220 are provided on the rib 111. As shown in FIG. 4, the sub-member working tooth 220 includes a sub-member base 221, a connecting portion 222, and a tooth portion 223. The tooth portion 223 slides in the working tooth cavity 130, and by making its cross-section larger than that of the main slide portion 140, it is ensured that the sub-member working tooth 220 does not directly disengage from the main member working tooth 120. The connecting portion 222 slides in the main slide portion 140, and the sub-member base 221 is connected to the sub-member tape 210.

[0042] As shown in FIG. 1, the first position limiting member 300 is provided at both left and right ends of the main member working teeth 120 queue. Referring to FIG. 9, the first position limiting member 300 includes a position limiting base 310 and an elastic member 320. Taking the engagement of the left first position limiting member 300 and the second position limiting member 400 as an example, the right vertical surface of the elastic member 320 is higher than the bottom surface of the slide rail of the main member working teeth 120, and the upper surface of the elastic member 320 does not exceed the lower surface of the sub-member working teeth 220. Further, the sub-member working teeth 220 directly slide out from the first position limiting member 300a on the left side of the slide rail, and the lower surface of the second position limiting member 400a is lower than the upper surface on the right side of the elastic member 320.

[0043] When in the first position, the left side surface of the second position limiting member 400a abuts against the right side surface of the first position limiting member 300a. Further, the first position limiting member 300a restricts the continuous leftward movement of the sub-member unit 200. At this time, the sub-member working teeth 220 on the left side of the second position limiting member 400a are already located outside the slide rail, and the sub-member working teeth 220 on the right side of the second position limiting member 400a are located inside the slide rail.

[0044] When in the second position, the right side surface of the second position limiting member 400b abuts against the left side surface of the first position limiting member 300b. Further, the first position limiting member 300b restricts the mechanical rightward movement of the sub-member unit 200. At this time, the right side of the second position limiting member 400b is already located outside the slide rail, and the sub-member working teeth 220 on the left side of the second position limiting member 400b are located inside the slide rail.

[0045] As shown in FIG. 4, the queues of the sub-member working teeth 220 are arranged in the left-right direction. The second position limiting member 400a and the second position limiting member 400b are symmetrically provided on the sub-member working teeth 220 queue. In this embodiment, the total length of the main member working teeth 120 queue is 52 cm, the total length of the sub-member working teeth 220 queue is 52 cm, the total length of the sub-member working teeth 220 queue on the left side of the second position limiting member 400a is 7 cm, and the total length of the sub-member working teeth 220 queue on the right side of the second position limiting member 400b is 7 cm.

[0046] The position limiting table 310 is connected to the elastic member 320. The elastic member 320 is located at both ends of the slide rail formed from the main member working teeth 120 and abuts against the second position limiting member 400, and further forms a position limit for the sub-member unit 200.

[0047] The position limiting working teeth 410 of the second position limiting member 400 and the sub-member working teeth 220 are connected to the sub-member tape 210 so as to be in a queue. One end of the position limiting working teeth 410 forms a convex portion 420, so that one end of the position limiting working teeth 410 protrudes from the sub-member working teeth 220. The convex portion 420 abuts against the elastic member 320, and further realizes the position limit for the sub-member unit 200.

[0048] As shown in FIG. 10, the convex portion 420 of the position limiting working teeth 410 extends to the left side surface of the working teeth cavity 130. Here, due to the convex portion 420 of the position limiting working teeth 410, the contact surface between the adjacent sub-member working teeth 220 and the main member working teeth 120 becomes smaller, and further, the total contact area of the sub-member working teeth 220 queue is reduced, and the total frictional force is decreased.

[0049] As shown in FIG. 4, the position limiting working teeth 410 are formed in the sub-member working teeth 220 array so as to be in an array, and may be provided at both the left and right ends of the sub-member working teeth 220 array.

[0050] The surface of the convex portion 420 that contacts the working teeth cavity 130 is an arc-shaped surface, thereby reducing the frictional force. Specifically, as shown in FIG. 3, the peripheral edge portion of the convex portion 420 presents an arc-shaped chamfer. Similarly, the peripheral edge portion of the tooth portion 223 of the sub-member working teeth 220 is an arc chamfer. As shown in FIG. 4, the corner positions of the front edge and the rear edge of the convex portion 420 are arcs, and the corner positions of the front edge and the rear edge of the tooth portion 223 of the sub-member working teeth 220 are arcs.

[0051] The elastic member 320 seals both ends of the slide rail. When in the first position or the second position, the convex portion 420 of the second position limiting member 400 abuts against the elastic member 320, thereby preventing the sub-member unit 200 from detaching from the main-member unit 100. However, since the elastic member 320 itself has a distortion ability, when it receives a certain stress, it distorts. That is, when the second position limiting member 400 applies a force exceeding its own distortion to the elastic member 320, the position limiting tooth 410 detaches from the slide rail and the position limiting pedestal.

[0052] By arranging the elastic member 320 on the first position limiting member 300, the second elastic member 320 detaches from the slide rail and the position limiting pedestal. That is, the sub-member unit 200 detaches from the main-member unit 100. The detaching and attaching method is simple and effective, improving the manufacturing efficiency and being convenient for the user to operate.

[0053] As shown in FIG. 1, both the upper and lower ends of the position limiting base 310 are connected to the main member tape 110, arranged to form a queue with the main member working teeth 120, and a certain distance is provided between the position limiting base 310 and the main member working teeth 120 adjacent thereto. As shown in FIG. 6, within the position limiting base 310, a position limiting cavity 330 is formed along the left - right direction. The position limiting cavity 330 penetrates the position limiting base 310 in the left - right direction and penetrates the position limiting base 310 upward to form a sub - slide portion 340 extending in the left - right direction. The diameter of the position limiting cavity 330 is larger than that of the sub - slide portion 340 to prevent the tooth portion 223 from falling off from the sub - slide portion 340. The elastic member 320 is provided within the position limiting base 310 and connected to the position limiting base 310. The elastic member 320 divides the position limiting cavity 330 into an upper chamber portion 331 and a lower chamber portion 332. The upper chamber portion 331 communicates with the sub - slide portion 340. Both sides of the sub - member base 221 are connected to the sub - member tape 210. Thereby, the stability of the entire slide fastener structure is improved. After the connecting portion 222 slides out from the main slide portion 140, it enters the sub - slide portion 340. The tooth portion 223 of the sub - member working teeth 220 slides out from the slide rail and then enters the position limiting cavity 330, and then detaches from the position limiting pedestal from the position limiting cavity 330.

[0054] As shown in FIG. 6, the elastic member 320 includes an elastic sheet 321. The elastic sheet 321 is provided within the position-limiting cavity 330 and integrally formed with the position-limiting base 310. The elastic sheet 321 divides the position-limiting cavity 330 into an upper chamber portion 331 and a lower chamber portion 332. As shown in FIG. 7, the position-limiting base 310 extends along the left-right direction, the elastic sheet 321 extends along the left-right direction, the right end of the elastic sheet 321 reaches the right end of the position-limiting base 310, and the right end of the position-limiting base 310 forms a receiving portion 350 that protrudes to the right. Thereby, the distance between the elastic sheet 321 and the right-side main member working tooth 120 is reduced. As shown in FIG. 8, the upper surface of the elastic sheet 321 forms a first inclined surface 322 that gradually increases from left to right. Due to the first inclined surface 322, the position-limiting working tooth 410 can easily enter the slide rail. Also, after deforming the elastic member 320, the position-limiting working tooth 410 can quickly slide out from the position-limiting cavity 330. As shown in FIG. 8, the elastic sheet 321 extends in the left-right direction. From the left end of the elastic sheet 321 to the left side of the position-limiting base 310, a distance of 1 / 4 to 1 / 3 is provided. The vertical surface on the right side of the elastic sheet 321 is thick, the upper surface at the right end of the elastic sheet 321 is higher than the bottom surface of the working tooth cavity 130, and the lower surface at the right end of the elastic sheet 321 is lower than the bottom surface of the working tooth cavity 130.

[0055] The position-limiting working tooth 410 is the sub-member working tooth 220, and the convex portion 420 forms a second inclined surface 421 along the extending direction of the sub-member tape 210. Specifically, as shown in FIG. 4, the position-limiting working teeth 410 are arranged in an array of sub-member working teeth 220, and their upper surfaces form the second inclined surface 421. The second inclined surface 421 gradually descends from the end of the sub-member tape 210 to the middle position of the sub-member tape 210. By engaging the first inclined surface 322 and the second inclined surface 421, the sub-member tape 210 can be easily attached to the main-member tape 110. When the sub-member tape 210 detaches from the main-member tape 110, the required stress is consistent with the situation without inclined surfaces, thereby improving the operation experience.

[0056] As shown in FIG. 4, the first-stage portion 230a is the sub-member engaging tooth 220 queue on the left side of the second position-limiting member 400a, the first-stage portion 230b is the sub-member engaging tooth 220 queue on the right side of the second position-limiting member 400b, and the second-stage portion 240 is the sub-member engaging tooth 220 queue between the two second position-limiting members 400.

[0057] As shown in FIG. 8, the length of the position-limiting wall 311 extending in the left-right direction of the position-limiting engaging tooth 410 is the same as the length of the position-limiting base 310 in the left-right extending direction. As shown in FIG. 4, the tooth portion 223 extends in the left-right direction, and the ratio of the length of the position-limiting wall 311 of the position-limiting base 310 to the length of the left-right extension of the tooth portion 223 is 1.2. The interval between the tooth portions 223 of every two adjacent sub-member engaging teeth 220 is 0.5 mm. Due to such a ratio, when the sub-member engaging tooth 220 of the first-stage portion 230 slides into the slide rail, the position-limiting base 310 does not enter the gap between the adjacent sub-member engaging teeth 220, and furthermore, smoothness is guaranteed.

[0058] In other embodiments, the ratio of the length of the position-limiting wall 311 of the position-limiting base 310 to the length of the left-right extension of the tooth portion 223 is 1.3, 1.4, 1.5, 1.6, and the interval between the tooth portions 223 of every two adjacent sub-member engaging teeth 220 is 0.5 mm, 0.45 mm, 0.4 mm, 0.35 mm, 0.3 mm, 0.25 mm, 0.2 mm. Each embodiment may be any combination and arrangement of the above numerical values.

[0059] In other embodiments, the ratio of the length of the position-limiting wall 311 of the position-limiting base 310 to the length of the left-right extension of the tooth portion 223 is 1.5, and the interval between the tooth portions 223 of every two adjacent sub-member engaging teeth 220 is 0.3 mm.

[0060] The sub-member working teeth 220 in the first-stage portion 230 are attached to the sub-member tape 210 at equal distances, the sub-member working teeth 220 in the second-stage portion 240 are attached to the sub-member tape 210 at equal distances, the distance between the sub-member working teeth 220 in the first-stage portion 230 is smaller than the distance between the adjacent sub-member working teeth 220 in the second-stage portion 240, the distance between the sub-member working teeth 220 in the second-stage portion 240 is 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and by arranging the second-stage portion 240 to have a large pitch, the bending degree of the sub-member unit 200 at the position of the second-stage portion 240 becomes larger, which is convenient for folding and storing.

[0061] Also, in another embodiment, the position-limiting working teeth 410 are the sub-member working teeth 220, and the convex portions 420 are arranged at intervals in the working tooth array of the sub-member working teeth 220, thereby forming the second position-limiting member 400 arranged at intervals. The total lengths of the convex portions 420, the tooth portions 223, and the connecting portions 222 are larger than the length from the opening of the main slide portion 140 to the inner wall of the working tooth cavity 130.

[0062] The position-limiting working teeth 410 are the sub-member working teeth 220, and on one side of the sub-member working teeth 220 of the second position-limiting member 400, convex portions 420 are formed. That is, in the queue of the sub-member working teeth 220, convex portions 420 are formed on the spaced-apart sub-member working teeth 220. Specifically, as shown in FIG. 4, the position-limiting working teeth 410 include a sub-member base 221, a connecting portion 222, and a tooth portion 223. Their shapes and positions correspond to the queue of the sub-member working teeth 220. Above the tooth portion 223 of the position-limiting working teeth 410, convex portions 420 are formed. Referring to FIG. 5, the tooth portion 223 of the sub-member working teeth 220 gradually decreases in cross-sectional area from bottom to top, and its peripheral surface is an arcuate chamfer. Above the tooth portion 223 of the position-limiting working teeth 410, convex portions 420 are formed to protrude upward, and any surface of the convex portions 420 is an arcuate surface.

[0063] Here, as shown in FIG. 10, the total length of the convex portion 420, the tooth portion 223, and the connecting portion 222 is greater than the length from the opening of the main slide portion 140 to the inner wall of the tool tooth cavity 130. That is, the distance from the contact point between the leftmost side of the convex portion 420 and the tool tooth 120 of the main member to the sub-member base 221 is greater than the distance from the contact point between the tool tooth cavity 130 and the convex portion 420 to the position of the right main slide portion 140 of the tool tooth 120 of the main member. That is, during the sliding process of the tool tooth 120 of the main member and the tool tooth 220 of the sub-member, the left side surface of the sub-member base 221 and the right side surface of the tool tooth 120 of the main member do not contact each other, further reducing the frictional force. Regarding the stability of the structural connection, the engagement between the connecting portion 222 and the main slide portion 140 realizes the effect of stable connection.

[0064] In another embodiment, the duty tooth cavity 130 includes a first chamber portion 131 and a second chamber portion 132 that communicate with each other. The first chamber portion 131 is engaged with the position-limiting duty tooth 410 and the sub-member duty tooth 220, and the second chamber portion 132 is engaged with the convex portion 420. As a result, the position-limiting duty tooth 410 and the sub-member duty tooth 220 slide in the first chamber portion 131 arranged in sequence, and the convex portion 420 slides in the second chamber portion 132 arranged in sequence. As shown in FIG. 10, the main member duty tooth 120 has two horizontal wall surfaces formed on the sliding portion. The upper and lower wall surfaces of the first chamber portion 131 are both arc-shaped. When the sub-member duty tooth 220 is located in the main member duty tooth 120, a difference value is formed between the upper and lower thicknesses of the connecting portion 222 and the pitch in the vertical direction of the sliding portion position of the main member duty tooth 120. The difference value is 0.2 mm or more and 0.5 mm or less. In this embodiment, 0.3 mm is adopted. In other embodiments, it may be 0.25 mm, 2.35 mm, 0.4 mm, or 0.45 mm. Similarly, on the same vertical plane, a difference value is formed between the left-right thickness of the tooth portion 223 and the distance between the upper and lower wall surfaces of the first chamber portion 131. The difference value is 0.2 mm or more and 0.8 mm or less. In this embodiment, 0.4 mm is adopted. In other embodiments, 0.3 mm, 0.5 mm, 0.6 mm, or 0.7 mm may be adopted. The sizes of the sub-member duty tooth 220, the sliding portion, and the duty tooth cavity are designed to cooperate with the arc-shaped surface of the sub-member duty tooth 220 in the slide rail to lock the movable range of the sub-member duty tooth 220, prevent the convex portion 420 from entering the first chamber portion 131, avoid the activity range of the sub-member duty tooth 220 from being too large, and ensure excellent smoothness.

[0065] In another embodiment, the edge of the tooth portion 223 is arc-shaped. A first plane 223a is formed on the side of the tooth portion 223 facing the main slide portion 140. At the connection location between the main tooth cavity 130 and the main slide portion 140, a second plane 120a that engages with the first plane 223a is formed. Specifically, as shown in FIG. 10, the convex portion 420 is formed on the side of the tooth portion 223 away from the main slide portion 140. Referring to FIG. 10, the main slide portion 140 of the main member main tooth 120 faces to the right, and the left side of the tooth portion 223 forms the convex portion 420. Since the convex portion 420 gradually transitions and tapers into an arc shape from the tooth portion 223 towards the left cross-section, the left side of the convex portion 420 is linearly connected to the left side surface of the main tooth cavity 130. The left side surface of the tooth portion 223 is a plane and is connected to the plane of the elastic sheet 321 with a gap. As shown in FIG. 10, the main tooth cavity 130 includes a first chamber portion 131 and a second chamber portion 132. The first chamber portion 131 communicates with the main slide portion 140. The wall surfaces of the upper side and the lower side of the first chamber portion 131 gradually transition to be arc-shaped. The second chamber portion 132 is connected to the first chamber portion 131 so as to gradually transition while spreading from left to right. Further, the side of the sub-member main tooth 220 is linearly connected to the wall surface of the first chamber portion 131, and the side of the convex portion 420 is linearly connected to the wall surface of the second chamber portion 132.

[0066] Both the upper and lower side surfaces of the tooth portion 223 are arc-shaped surfaces and are engaged with the arc-shaped surface of the first chamber portion 131. The right side of the tooth portion 223 forms the first plane 223a. At the position where the main tooth cavity 130 engages with the first plane 223a, a second plane 120a is formed. By the engagement between the first plane 223a and the second plane 120a, and the engagement between the tooth portion 223 and the arc-shaped surface of the first chamber portion 131, the sub-member main tooth 220 is under the action of force receiving, and its plane is engaged with the arc-shaped surface to form an excellent connection relationship, further ensuring the smoothness of the slide fastener.

[0067] A piece of clothing, including a slide fastener, a first piece of clothing and a second piece of clothing. The first piece of clothing is connected to the main member tape 110, and the second piece of clothing is connected to the sub-member tape 210. Thus, the first piece of clothing and the second piece of clothing can slide relative to each other. Specifically, the body of the clothing is connected to the main member tape 110, and the hat is connected to the sub-member tape 210. As shown in Figure 10, by positioning the main member unit 100 and the sub-member unit 200 in the same plane, the body of the clothing and the hat can slide relative to each other.

[0068] Here, the embodiments described in this application are illustrative rather than restrictive. Therefore, this application is not limited to the embodiments described in specific implementation forms. Any other embodiments obtained by those skilled in the art based on the technical solutions of this application also belong to the protection scope of this application.
