Description

Technical Field

[0001] The invention belongs to the field of zippers, and in particular relates to an invisible slider capable of arbitrarily hovering and pulling a card. Background Art

[0002] The invisible slider has a small exposed area after installation, and the zipper teeth of the zipper installed with this type of slider are not exposed, which is beneficial to improving the aesthetics of the product and allowing more room for product design.

[0003] In the prior art, the patent document with application number "CN201610105490.0" discloses a zipper slider and a zipper, which achieves the effect of arbitrary hovering by setting a pair of claws to tightly grip the rotating shaft of the rubber pull card. However, in actual production, no matter what processing technology is used (such as riveting, which is the most commonly used in zipper processing) to achieve the gripping effect of the claws on the pull card rotating shaft, since the pull card and the claws are in direct contact, the distance between the equipment and the pull card during processing is extremely close, which may cause processing marks (such as indentations, scratches, etc.) on the surface of the pull card, which is not conducive to the application of the slider in high-end products with strict requirements on product appearance. Moreover, the slider itself is a tiny part, and the claws as part of the slider are smaller in size and are prone to breakage during processing. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes an invisible slider for arbitrarily hovering and pulling a card, so as to overcome the above-mentioned technical problems existing in the existing related art.

[0014] Preferably, the height of the blocking protrusion is greater than the height of the bayonet, and when the pressure-bearing portion of the end pressure piece is placed in the pressure piece groove but before riveting, the blocking protrusion arches the end pressure piece, and the bottom surface of the end pressure piece does not contact the bottom of the pressure piece groove.

[0015] Preferably, the top surface of the guide post is provided with a lower groove, the bottom of the lower groove protrudes upward to form a boss, and the top surface of the boss is concave to form a positioning groove;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figures 1 to 7 As shown, an invisible slider with an arbitrary hovering pull tag includes a zipper slider body 1 and a pull tag 2.

[0039] The zipper head body 1 includes a base 102, a guide column 101 is provided on one side of the middle part of the top surface of the base 102, and a left-side stop 103 and a right-side stop 104 are symmetrically provided on the left and right sides of the base 102. The top ends of the left-side stop 103 and the right-side stop 104 extend inward, and the space enclosed by the left-side stop 103 and the right-side stop 104 forms a Y-shaped chain channel under the separation of the guide column 101, and the opening of the chain channel faces upward for the chain teeth to be inserted.

[0040] The pull card includes a rotating shaft arranged at the front end for connecting with the zipper head body.

[0041] This embodiment further includes an end pressure piece 3 mounted on the top of the guide post 101. The front end of the end pressure piece 3 is a pressure-bearing portion, and the rear end is a pressure-applying portion. A riveting portion 105 is provided at the top of the guide post 101 at a position corresponding to the pressure-bearing portion. The riveting portion 105 rivets and fixes the pressure-bearing portion at the front end of the end pressure piece 3.

[0042] The rotating axis of the card puller 2 is clamped between the pressure part at the rear end of the end pressure piece 3 and the guide column 101 to form a rotating connection. Under the pressure of the pressure part, the rotating axis of the card puller 2 contacts the pressure part and the guide column 101 and there is friction. This friction allows the card puller 2 to rotate to any angle and hover.

[0043] First, the provision of the end pressing member 3 not only enables the pull card 2 to achieve an arbitrary hovering effect, but also enables the riveting device to press the end pressing member 3 instead of contacting the pull card 2 during riveting, thereby avoiding causing processing marks (such as indentations, scratches, etc.) on the pull card 2, which is conducive to the application of this embodiment to high-end products with strict requirements on product appearance;

[0044] Secondly, since the present embodiment fastens the end pressing member 3 by riveting, rather than directly fastening the pull card 2 by riveting, a relatively large riveting portion 105 can be provided, which facilitates riveting processing and is not easy to break;

[0045] Finally, the end pressure piece 3 only rivets the pressure-receiving part at the front end, so that the pressure-applying part at the rear end is not locked, and the pressure-applying part has a small elastic deformation effect, which can adapt to more sizes of rotating shafts.

[0046] Specifically, the card pull 2 can be made of a hard material or a flexible material. When the card pull 2 is made of a hard material, the card pull 2 and the end pressure piece 3 and the guide column 101 should be controlled to be in transition fit, that is, the card pull 2 can be suspended arbitrarily without the action of external force, and the card pull 2 can be rotated if there is an external force. Taking into account that the transition fit of hard materials requires more precise production size requirements, the card pull 2 is preferably made of a flexible material that can produce elastic deformation (such as rubber, etc.). The card pull 2 of this embodiment is a resin card pull. The card pull 2 made of flexible material has a relatively loose range for limiting the clamping force of the end pressure piece 3 while ensuring that it can be rotated, which can reduce the requirements of this embodiment on processing accuracy.

[0047] Specifically, the end pressure piece 3 is made of rigid metal and is provided separately from the zipper head body 1 so that the rear end thereof is not locked and has a small elastic deformation effect.

[0048] In this embodiment, an open positioning groove 106 is provided on the top of the guide column 101 for placing the rotating shaft of the card pull 2, which is convenient for positioning the card pull 2 before riveting. The pressure-applying portion of the end pressure piece 3 is surrounded by the open end of the positioning groove 106 to form a connecting hole. The rotating shaft of the card pull 2 is installed in the connecting hole to form a rotating connection. The rotating shaft of the card pull 2 is in contact with the wall of the connecting hole and there is friction. This friction enables the card pull 2 to rotate to any angle and hover.

[0049] Specifically, the positioning groove 106 is a concave arc structure, and the pressure-applying part of the end pressure piece 3 is a bending arm 301. The bending arm 301 is surrounded by the open end of the positioning groove 106 to form the connecting hole, which can increase the contact area between the pull card 2 and the positioning groove 106 and the end pressure piece 3 to achieve a hovering effect, and at the same time is conducive to the rotation of the pull card 2.

[0050] In this embodiment, the bending arm 301 serves as the end structure of the end pressure piece 3. In actual production, the bending arm 301 can be produced so that the end portion is just connected to the open end of the positioning groove 106, thereby enclosing the connecting hole. However, considering that the end pressure piece 3 may be slightly deformed after riveting, that is, the bending arm 301 may be slightly warped, long-term pulling on the pull card 2 may also cause the bending arm 301 to be warped, thereby causing a gap between the end portion of the bending arm 301 and the open end of the positioning groove 106, affecting the clamping effect of the bending arm 301 on the end pressure piece 3. Therefore, the top surface of the guide column 101 is provided with a downwardly concave slot 10 7. The slot 107 is located on one side of the positioning slot 106, and the bending arm 301 spans the open end of the positioning slot 106 to enclose the connecting hole, and the end of the bending arm 301 is inserted into the slot 107. This design ensures that the bending arm 301 has sufficient length, and even if it is slightly warped, it still remains in an enclosed state with the open end of the positioning slot 106. Since it does not need to be connected to the open end of the positioning slot 106, the production accuracy requirement is also reduced to a certain extent. Moreover, the design of the slot 107 can prevent the bending arm 301 from deforming such as warping, thereby reducing the influence of long-term pulling of the pull card 2 on the clamping effect of the end pressure piece 3.

[0051] In this embodiment, a downwardly concave pressure piece groove 108 is provided on the top of the guide column 101, and the pressure-bearing part of the end pressure piece 3 is placed in the pressure piece groove 108. The left and right displacements of the end pressure piece 3 are limited by the pressure piece groove 108. The riveting parts 105 are provided on both sides of the notch of the pressure piece groove 108. The main function of the riveting parts 105 is to position the end pressure piece 3 to prevent the end pressure piece 3 from moving during riveting, reduce the protrusion of the end pressure piece 3 on the surface of the zipper head body 1, and make the appearance of this embodiment smoother and simpler.

[0052] More specifically, the top surface of the guide column 101 is provided with a lower groove, the bottom of the lower groove protrudes upward to form a boss, and the top surface of the boss is concave to form a positioning groove 106. The boss divides the lower groove into an upper groove body and a lower groove body. The upper groove body is the pressing groove 108, and the lower groove body is set as a slot 107. The structure is simple and convenient for production and processing.

[0053] In this embodiment, a blocking protrusion 109 is provided in the pressure piece groove 108, and the end pressure piece 3 is provided with a bayonet 302 adapted to the blocking protrusion 109, and the bayonet 302 is clamped in the blocking protrusion 109. The sliding of the end pressure piece 3 in the pressure piece groove 108 is restricted by the blocking protrusion 109, further positioning the end pressure piece 3 to ensure that the end pressure piece 3 does not move during riveting. At the same time, when pulling the pull card 2, the bending arm 301 and the positioning groove 106 are prone to collision and force. As the usage time increases, long-term collision may cause the bending arm 301 to deform. The blocking protrusion 109 can share the pulling force to avoid the deformation problem of the bending arm 301 caused by multiple collisions.

[0054] Reference Figure 7 In this embodiment, the height of the blocking protrusion 109 is greater than the height of the bayonet 302. When the pressure-bearing part of the end pressure piece 3 is placed in the pressure piece groove 108 but before riveting, the blocking protrusion 109 arches the end pressure piece 3, and the bottom surface of the end pressure piece 3 does not contact the bottom of the pressure piece groove 108, so that the riveted part of the end pressure piece 3 may produce downward deformation after riveting, and an elastic space is reserved to avoid the end pressure piece 3 from colliding with the bottom of the groove.

[0055] Reference Figures 1 to 7 The riveting portion 105 can be designed to only rivet the middle of the end pressing piece 3, and the bending arm 301 serves as the rear end of the end pressing piece 3. It should be noted that riveting the middle of the end pressing piece 3 may cause the front end of the end pressing piece 3 to slightly warp up. Therefore, before the end pressing piece 3 is placed in the pressing piece groove 108 but not riveted, the front end outer surface of the end pressing piece 3 is lower than the notch of the pressing piece groove 108 (such as Figure 7 As shown), a height is reserved for the possible upward warping of the front end of the end pressing member 3 to prevent the front end of the end pressing member 3 from protruding from the surface of the zipper head body 1.

[0056] More specifically, the riveting portion 105 is designed to rivet only the middle portion of the end pressing piece 3, and its width is designed to be wide at the front and narrow at the back, thereby forming a tightening effect on the end pressing piece 3 that is tight at the front and loose at the back, thereby cooperating with the pressure portion to have a small elastic deformation effect.

[0057] Reference Figure 8 and Figure 9 The riveting portion 105 can also be designed to rivet the front end and middle part of the end pressing piece 3, and the bending arm 301 serves as the rear end of the end pressing piece 3. This design has a larger riveting area, is not easy to break, and has a reliable fixing effect. At the same time, it can avoid the problem of slight upward warping of the front end of the end pressing piece 3 mentioned above.

[0058] In this embodiment, the zipper head body 1 includes a base 102, and one side of the middle part of the top surface of the base 102 is convex to form a guide column 101. The top of the guide column 101 is provided with a top that is larger than the width of the guide column 101 body and has a pointed end. The left and right sides of the base 102 are first convex to form side walls, and the top ends of the side walls extend toward each other to form a top, forming a symmetrical left stop 103 and a right stop 104. The tip of the guide column 101 is inserted between the left stop 103 and the right stop 104. The left stop 103, the right stop 104 and the guide column 101 together form a Y-shaped chain closing channel.

[0059] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
