DETAILED DESCRIPTION

[0036] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, but not to limit the application. The described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0037] It should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0038] Hereinafter, the terms "first", "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.

[0039] Please refer to Figures 1-16 .

[0040] The present application discloses a locking slider of an invisible zipper, comprising a pull tab 1, a slider body 2 and a hook 3. Specifically, the pull tab 1 and the hook 3 are both mounted on the slider body 2, and the pull tab 1 is fixed to the slider body 2 via the hook 3.

[0041] A first cross bar 11 is provided at one end of the pull tab 1, and the first cross bar 11 includes a hinge portion and a protrusion 111 protruding from the outer peripheral surface of the hinge portion; a hinge groove 211 that rotates with the hinge portion is provided on the mold nose 21 of the slider body 2, so that the pull tab 1 can rotate on the slider body 2, and a limiting groove 212 that limits the position of the protrusion 111 is provided on the slider body 2. The limiting groove 212 is opened at the bottom of the hinge groove 211, and the protrusion 111 cooperates with the limiting groove 212 to limit the movement of the pull tab 1 along the axial direction of the first cross bar 11 to reduce the shaking of the pull tab 1.

[0042] At least one end of the hook 3 can be inserted into the chain tooth. The hook 3 is inserted into the chain tooth to lock the slider body 2, and the hook 3 is disengaged from the chain tooth to release the locking of the slider body 2.

[0043] The protrusion 111 has a touch portion that pushes the hook 3 when the pull tab 1 rotates to form a preset angle with the lower surface of the slider body 2, thereby disengaging the hook 3 from the chain teeth and releasing the lock on the slider body 2. In this solution, the slider body 2 is switched between the locked state and the unlocked state by rotating the protrusion 111.

[0044] The touch portion of the protrusion 111 is where the protrusion 111 can contact the hook 3 and apply a thrust to the hook 3. When the pull tab 1 is rotated to a predetermined angle with the lower surface of the slider body 2, the touch portion of the protrusion 111 contacts the hook 3 and applies a thrust to the hook 3. If the pull tab 1 continues to rotate beyond the predetermined angle, the touch portion of the protrusion 111 will continue to push the hook 3, disengaging the hook 3 from the chain teeth and releasing the lock of the slider body 2. If the pull tab 1 is rotated in the opposite direction until it returns to its initial position, the hook 3 will be inserted and connected, locking the slider body 2.

[0045] The lower surface of the slider body 2 is the surface of the slider body 2 located on the inner side of the cloth tape, and the inner side of the cloth tape is the side of the cloth tape close to the inside of the garment.

[0046] The preset angle is flexibly designed by those skilled in the art according to actual needs and can be 5°, 10° or other angles, which are not limited here.

[0047] The locking slider of the invisible zipper disclosed in the present application includes a pull tab 1, a slider body 2, and a hook 3. A hinge portion and a protrusion 111 are provided on the first crossbar 11 of the pull tab 1, and a hinge groove 211 that rotates with the hinge portion and a limit groove 212 that limits the protrusion 111 are provided on the mold nose 21 of the slider body 2. The pull tab 1 is installed on the slider body 2, with the hinge portion located in the hinge groove 211 and the protrusion 111 located in the limit groove 212. When the pull tab 1 rotates, the hinge portion rotates in the hinge groove 211 and the protrusion 111 moves in the limit groove 212. When the pull tab 1 rotates to a preset angle with the lower surface of the slider body 2, the protrusion 111 can push the hook 3. When the pull tab 1 continues to rotate, the protrusion 111 pushes the hook 3 out of the chain teeth, unlocking the slider body 2. During the rotation of the pull tab 1, a part of the protrusion 111 is always located in the limiting groove 212. The limiting groove 212 can always limit the protrusion 111, restricting the pull tab 1 from moving along the axial direction of the first cross bar 11, thereby reducing the shaking of the pull tab 1 during flipping and use, and improving the use effect of the invisible zipper.

[0048] In the present application, the protrusion 111 can not only limit the movement of the pull tab 1 along the length direction of the first cross bar 11 , but also push the horse hook 3 to unlock the slider body 2 .

[0049] Preferably, the hinge portion of the first crossbar 11 and the protrusion 111 are integrally formed.

[0050] like Figure 3 As shown, the protrusion 111 is an arc-shaped protrusion, and when the side of the arc-shaped protrusion contacts the horse hook 3, the arc-shaped protrusion can push the horse hook 3. Preferably, the limiting groove 212 is an arc-shaped limiting groove.

[0051] The curvature of the arc-shaped projection determines the size of the preset angle. Preferably, the projection 111 is coaxially arranged with the hinge portion.

[0052] In some embodiments of the present application, the arc angle of the arc-shaped protrusion is 180°, and the pull tab 1 can push the hook 3 by rotating a small angle, thereby improving the reliability of unlocking the slider body 2.

[0053] like Figure 10 As shown, the pull tab 1 is in the first working position, the pull tab 1 is located at the front end of the slider body 2 and the rotation angle is 0°, the protrusion 111 does not apply thrust to the hook 3, and the hook 3 is inserted into the chain tooth;

[0054] like Figure 11As shown, the pull tab 1 is in the second working position, the pull tab 1 is located at the front end of the slider body 2 and rotated at a certain angle, which is less than 90 degrees. The protrusion 111 applies a thrust to the hook 3, and the hook 3 is disengaged from the chain teeth, but the hook 3 is not pushed up to the highest position. When the pull tab 1 continues to rotate to 90 degrees, the protrusion 111 applies a thrust to the hook 3, and the hook 3 is pushed up to the highest position.

[0055] like Figure 11 As shown, the pull tab 1 is in the third working position, the pull tab 1 is located at the rear end of the slider body 2 and rotated at a certain angle, which is greater than 90° and less than 180°. The protrusion 111 applies a thrust to the hook 3, the hook 3 disengages from the chain teeth, and the height of the hook 3 is lowered.

[0056] like Figure 12 As shown, the pull tab 1 is located in the fourth working position, the pull tab 1 is located at the rear end of the slider body 2 and rotated at a certain angle, which is close to 180°. The protrusion 111 applies a thrust to the horse hook 3, the horse hook 3 disengages from the chain teeth, and the pushed height of the horse hook 3 decreases.

[0057] Here, the front and back are explained. An engagement outlet is provided at one end of the slider body 2, and two introduction ports are provided at the other end of the slider body 2. In this scheme, the direction where the introduction port of the slider body 2 is located is named front, and the direction where the engagement port of the slider body 2 is located is named rear.

[0058] In the embodiment where the arc angle of the arc-shaped protrusion is 180°, the arc-shaped protrusion rotates 180° with the pull tab 1, and a part of the arc-shaped protrusion is always located in the limiting groove 212, ensuring that the limiting groove 212 can always limit the protrusion 111, thereby solving the problem of shaking of the pull tab 1 during rotation to the greatest extent.

[0059] Preferably, the arc angle of the arc-shaped protrusion is no greater than 180°.

[0060] The horse hook 3 can be installed on the slider body 2 through its own structure, and can also be installed on the slider body 2 through the elastic cover plate 4.

[0061] In an embodiment in which the locking slider of the invisible zipper further includes a spring cover plate 4 , the spring cover plate 4 is connected to the slider body 2 and can press the clasp 3 onto the slider body 2 .

[0062] like Figure 3 As shown, the slider body 2, the pull tab 1, the horse hook 3 and the spring cover 4 are arranged in sequence.

[0063] The spring cover plate 4 is provided with a pressing portion that applies pressure to the hook 3 to drive the hook 3 toward the direction of insertion into the chain element, thereby reducing the swinging of the pull tab 1 around the axis of the first crossbar 11 when the pull tab 1 is stationary or rotating. The force applied by the pressing portion to the hook 3 is directed toward the lower surface of the slider body 2.

[0064] When the puller 1 rotates, the hook 3 is lifted, and the compression part of the spring cover plate 4 is also lifted. Since the spring cover plate 4 is fixed on the puller body 2, the compression part will generate a pressure to press the hook 3, and then the hook 3 will transmit the pressure to the first horizontal rod 11, thereby increasing the rotation damping of the puller 1, and reducing the swing of the puller 1 around the axis direction of the first horizontal rod 11 when rotating.

[0065] When the puller 1 is static, that is, before the puller 1 is flipped, after the spring cover plate 4 is installed on the puller body 2, the compression part will apply pressure to the hook 3, and then the hook 3 will transmit the pressure to the first horizontal rod 11, thereby increasing the rotation damping of the puller 1, and reducing the swing of the puller 1 around the axis direction of the first horizontal rod 11 when static.

[0066] The arrangement of the compression part can effectively reduce the swing of the puller 1 around the axis direction of the first horizontal rod 11 due to the movement of the user, thereby avoiding the puller 1 and the teeth from making a sound due to collision, and improving the use effect of the invisible zipper.

[0067] The compression part can continuously apply pressure to the hook 3 during the rotation of the puller 1, and the force applied by the compression part on the hook 3 gradually increases with the rotation of the puller 1 before the hook 3 is lifted to the highest position. The hook 3 transmits the pressure to the first horizontal rod 11, which to some extent plays a role in pressing the protrusion 111 into the limiting groove 212, preventing the protrusion 111 from coming out of the limiting groove 212 during the rotation of the puller 1, and improving the stability and reliability of the use of the lock puller.

[0068] In some embodiments of the present application, the compression part is a spring 41.

[0069] The compression part always applies pressure to the hook 3, and when the puller 1 rotates from the front end of the puller body 2 to the rear end of the puller body 2, the hook 3 can be inserted into the teeth under the pressure of the compression part, effectively locking the puller body 2.

[0070] As shown in Figure 8 , the spring 41 includes a horizontal segment and an arc segment, wherein the horizontal segment can be attached to the hook 3, one end of the arc segment is connected to the horizontal segment, and the other end of the arc segment is connected to the spring cover plate 4. When the puller 1 rotates, the protrusion 111 pushes the hook 3 to move, the hook 3 extrudes the horizontal segment of the spring 41, the arc segment deforms, and the arc segment can apply force to the horizontal segment to press the hook 3.

[0071] The arc segment can have the structure as shown in Figure 8 , and the recess of the arc segment faces the space between the horizontal segment and the spring cover plate 4; the recess of the arc segment can also face away from the space between the horizontal segment and the spring cover plate 4 (not shown in the figure).

[0072] The arc segment can have the structure as shown in Figure 8 .The structure shown in the figure has only one bend, but it can also be a wavy structure with multiple arc bends (not shown in the figure).

[0073] like Figure 8 As shown, the front end of the horse hook 3 is not inserted into the chain teeth, and the rear end of the horse hook 3 is inserted into the chain teeth. In this solution, the pressing part is arranged at the front end of the spring cover plate 4 to press the front end of the horse hook 3.

[0074] The pressing portion can also be arranged in the middle of the spring cover 4 (not shown in the figure), and the pressing portion presses the middle of the clasp 3, at which time the front end and / or rear end of the clasp 3 can extend into the chain teeth.

[0075] The spring cover plate 4 is formed by stamping and bending a piece of elastic metal sheet. Preferably, the spring cover plate 4 and the pressing portion are integrally formed.

[0076] In other embodiments of the present application, Figure 14 and 15 As shown, the pressing portion further includes an abutment plate 42, which is connected to the spring cover plate 4 and is capable of abutting against the position of the corresponding protrusion 111 of the hook 3. In this embodiment, the abutment plate 42 cooperates with the spring 41 to compress the hook 3. The abutment plate 42 and the spring 41 simultaneously apply pressure to the hook 3, which can further reduce the swing of the pull tab 1 around the axis of the first crossbar 11 during both static and rotational processes, while ensuring that the protrusion 111 always rotates within the limiting groove 212.

[0077] The position where the abutment plate 42 is set on the spring cover plate 4 needs to be widened. The abutment plate 42 is made through a cutting process at the widened position of the spring cover plate 4. After the cutting is completed, the abutment plate 42 is bent toward the direction of the horse hook 3 and can abut against the horse hook 3. At the same time, a clearance groove is formed on the spring cover plate 4 for the abutment plate 42 to move.

[0078] The elastic piece 41 and the contact plate 42 are spaced apart from each other along the length direction of the elastic piece cover plate 4 .

[0079] The elastic sheet cover 4 is fixedly connected to the slider body 2 .

[0080] In some embodiments of the present application, a raised wall 213 is provided on the mold nose 21 of the slider body 2. A stepped surface 214 is provided on the raised wall 213 for supporting the spring cover plate 4. The raised wall 213 is deformed by machine punching to press the spring cover plate 4 against the stepped surface 214. The pressing portion is located below the stepped surface 214 to press the hook 3.

[0081] Preferably, a protruding wall 213 is provided at the front end of the slider body 2 and / or the rear end of the slider body 2 to fix the front end and / or the rear end of the elastic cover plate 4 .

[0082] The mold nose 21 is provided with a raised wall 213. Preferably, the raised wall 213 is arranged in pairs in the direction perpendicular to the axis of the first crossbar 11.

[0083] As shown in the drawings, the front end of the mold nose 21 is provided with a first raised wall 213, and the rear end of the mold nose 21 is provided with a second raised wall 213. By striking and deforming the first raised wall 213, the front end of the baffle cover plate 4 is fixed on the stepped surface 214, and by striking and deforming the second raised wall 213, the rear end of the baffle cover plate 4 is fixed on the stepped surface 214. Figure 4

[0084] In order to reduce the installation accuracy of the baffle cover plate 4 on the mold nose 21, the present application is provided with a first limiting portion on the mold nose 21, and a second limiting portion on the baffle cover plate 4, and the first limiting portion cooperates with the second limiting portion to limit the movement of the baffle cover plate 4 in the direction perpendicular to the axis of the first crossbar 11.

[0085] The mold nose 21 is provided with at least one first limiting portion, and the baffle cover plate 4 is provided with at least one second limiting portion, and the positions of the second limiting portions correspond to the positions of the first limiting portions one by one and the number of the second limiting portions is equal to the number of the first limiting portions.

[0086] In some embodiments of the present application, the first limiting portion is a limiting protrusion and / or a limiting groove, and the second limiting portion is a limiting groove and / or a limiting protrusion. Specifically, the first limiting portion is a limiting protrusion, and the second limiting portion is a limiting groove; or the first limiting portion is a limiting groove, and the second limiting portion is a limiting protrusion.

[0087] When the mold nose 21 is provided with at least two first limiting portions, all the first limiting portions can be limiting grooves or limiting protrusions, or a part of the first limiting portions are limiting grooves and the other part of the first limiting portions are limiting protrusions.

[0088] As shown in the drawings, the front end of the mold nose 21 is provided with a first limiting groove, the rear end of the mold nose 21 is provided with a first limiting protrusion, the front end of the baffle cover plate 4 is provided with a second limiting protrusion, and the rear end of the baffle cover plate 4 is provided with a second limiting groove. During installation, the front end of the mold nose 21 is limited and cooperated with the second limiting protrusion of the baffle cover plate 4 through the first limiting groove, and the first limiting protrusion of the rear end of the mold nose 21 is limited and cooperated with the second limiting groove of the baffle cover plate 4, so as to limit the movement of the baffle cover plate 4 in the direction perpendicular to the axis of the first crossbar 11. Figure 5 As shown in the drawings, the baffle cover plate 4 is provided with a bend, which faces the hook 3, so as to increase the distance between the baffle cover plate 4 and the hook 3, form a space for giving way, ensure that the hook 3 can be pushed up to the highest by the protrusion 111, and reduce the interference on the turning of the pull tab 1.

[0089] Figure 3 Figure 8 As shown in the drawings, the baffle cover plate 4 is provided with a bend, which faces the hook 3, so as to increase the distance between the baffle cover plate 4 and the hook 3, form a space for giving way, ensure that the hook 3 can be pushed up to the highest by the protrusion 111, and reduce the interference on the turning of the pull tab 1.

[0090] ​​​The harness hook 3 is a U-shaped harness hook comprising a rear vertical bar, a second cross bar, and a front vertical bar. The rear vertical bar and the front vertical bar are located at opposite ends of the lengthwise direction of the second cross bar. In this embodiment, the rear vertical bar is longer than the front vertical bar, and the rear vertical bar can be inserted into the chain teeth. The front vertical bar does not insert into the chain teeth, and the position of the second cross bar near the front vertical bar cooperates with the pressing portion of the spring cover 4. When the protrusion 111 pushes the harness hook 3, the rear vertical bar and the second cross bar are pushed up, and the rear vertical bar is pulled out of the chain teeth.

[0091] As the protrusion 111 is pushed, the rear end vertical rod is lifted. At this time, the height of the connection position between the rear end vertical rod and the second cross rod is higher than the height of other positions of the horse hook 3. In order to prevent the connection position between the rear end vertical rod and the second cross rod from contacting the spring cover 4, the present application provides an oblique rod at the connection position between the rear end vertical rod and the second cross rod, that is, the rear end vertical rod and the second cross rod are connected by the oblique rod, and the oblique rod is inclined from the second cross rod to the lower surface of the slider body 2, thereby lowering the height there, preventing the spring cover 4 from hindering the movement of the horse hook 3, and not affecting the flipping of the pull tab 1.

[0092] The horse hook 3 is formed by punching and bending a hard metal sheet with a certain elasticity.

[0093] like Figure 9 As shown, the second cross bar includes a first straight segment, an inclined segment and a second straight segment connected to each other, wherein the first straight segment is connected to the front vertical bar, the second straight segment is connected to the inclined bar, the inclined segment is located between the first straight segment and the second straight segment, there is a height difference between the first straight segment and the second straight segment, and the second straight segment is away from the lower surface of the slider body 2 relative to the first straight segment.

[0094] The hook 3 is mounted on the nose 21 of the slider body 2. The front end of the nose 21 is provided with a hook front end slot 215, and the rear end of the nose 21 is provided with a hook hole 216. The hook hole 216 is connected to the inner cavity of the slider body 2. The rear end vertical rod of the hook 3 passes through the hook hole 216 and is inserted into the chain tooth, and the front end vertical rod of the hook 3 is inserted into the hook front end slot 215. After the pull tab 1 is mounted on the nose 21, the hinge portion of the first crossbar 11 of the pull tab 1 protrudes from the hinge slot 211. The first straight segment can be pressed against the front end of the nose 21, and the second straight segment can be pressed against the hinge portion protruding from the hinge slot 211.

[0095] To further optimize the above technical solution, a slot for receiving the hook 3 is formed on the first crossbar 11. The slot has a width approximately equal to that of the hook 3. The slot and the hook 3 cooperate to reduce the shaking of the pull tab 1 along the axis of the first crossbar 11 during the flipping process. In this embodiment, the slot and the hook 3 cooperate to limit the first crossbar 11, and the protrusion 111 cooperates with the limiting groove 212 to effectively limit the first crossbar 11, reducing the shaking of the pull tab 1 along the axis of the first crossbar 11 during the flipping process.

[0096] Preferably, the locking groove and the protrusion 111 are arranged opposite to each other on both sides of the axial direction of the first crossbar 11 .

[0097] like Figure 6 As shown, the middle part of the pull tab 1 is provided with a bend. When the pull tab 1 is at the front end of the slider body 2, the rear end height of the pull tab 1 is lower than the front end height of the pull tab 1, thereby reducing the distance between the pull tab 1 and the chain teeth when the pull tab 1 is stationary.

[0098] The locking slider of the invisible zipper disclosed in the present application improves the stability and user experience of the product by changing the structure of the pull tab 1 and the slider body 2, and ensures that the pull tab 1 does not shake; the appearance of the slider is slightly changed and the size of the slider is not increased too much; the structure is simple, and the connection of the various components is achieved by machine striking, which is convenient for installation and production.

[0099] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. The scope of application involved in this application is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in this application to form a technical solution.
