Description

Technical Field

[0001] This utility model belongs to the field of zipper technology, specifically relating to a riveted concealed zipper pull. Background Technology

[0002] Because of their small exposed area after installation, the teeth of zippers with this type of zipper are not exposed, which helps to improve the aesthetics of the product and allows for greater design flexibility, making them very popular in the market.

[0003] The applicant previously developed an invisible zipper pull with arbitrary hovering tab, with announcement number CN217986854U. The invisible zipper pull includes a zipper head body, a tab, and an end clamp. The zipper head body includes a base, and the top surface of the base is provided with a guide post, a left side stop, and a right side stop to form a Y-shaped chain closing channel. The front end of the end clamp is a receiving part, and the rear end is a applying part. The top of the guide post is provided with a riveting part corresponding to the receiving part. The riveting part rivets and fixes the receiving part at the front end of the end clamp. The rotating shaft of the tab is clamped between the applying part at the rear end of the end clamp and the guide post to form a rotating connection. Under the pressure of the applying part, the rotating shaft of the tab contacts the applying part and the guide post and there is friction, so that the tab can be rotated to any angle and hovered.

[0004] The applicant conducted research on the downstream distributors of the product and learned that the riveting-related structures (such as end clamps and riveting parts) in the prior application are relatively convex and large in volume. As a concealed zipper pull product, the concealment effect is relatively poor. At the same time, the relatively convex riveting-related structures cause the zipper pull body to tend to tilt relative to the zipper when the zipper pull body slides, and there is room for improvement in the smoothness of pulling. Therefore, the structure of the prior application needs to be further refined and improved. Summary of the Invention

[0005] In view of the problems in the related technologies, this utility model proposes a riveted concealed zipper pull to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A riveted concealed zipper pull includes a pull body and a pulling member for moving the pull body, the pulling member including a connecting shaft portion for connecting with the pull body.

[0008] The pull body includes a base plate portion having a first plate surface and a second plate surface. The first plate surface protrudes outward to form a chain splitting boss. The left and right sides of the first plate surface extend upward to form two symmetrical side wing plates. The tops of the two side wing plates extend in a direction close to each other but do not contact each other or the chain splitting boss, forming a Y-shaped opening for the chain teeth to be engaged. The space formed by the two side wing plates together forms a Y-shaped chain engaging channel under the separation of the chain splitting boss.

[0009] The riveted concealed zipper also includes at least one fastener, each of which has a pressure-bearing portion and a pressure-applying portion. The pressure-applying portion is a U-shaped or C-shaped structure with an opening, and the pressure-bearing portion extends from one end of the pressure-applying portion in a direction other than the opening.

[0010] At least one of the fasteners is mounted on the outer top surface and / or the second plate surface of the chain boss, the fastener being mounted with its opening facing the outer surface of the pull body, and the connecting shaft portion of the pull member being disposed within the opening of the pressure application portion.

[0011] The pull body is provided with at least one outwardly protruding rivet post at the position corresponding to the pressure-bearing part. By riveting the rivet post, it is deformed and clamps the pressure-bearing part, thereby fixing the fastener to the pull body. The connecting shaft is sandwiched between the pressure-applying part and the outer surface of the pull body and forms a rotatable connection. Under the pressure of the pressure-applying part, the connecting shaft comes into contact with the pressure-applying part and the outer surface of the pull body and has friction. This friction allows the pulling member to rotate to any angle and stop.

[0012] After installation, the pressure-bearing part is closer to the interior of the pull body than the rotation axis of the connecting shaft, and the rotation axes of the pressure-bearing part and the connecting shaft are not on the same horizontal plane.

[0013] Compared with the prior application, the rivet posts of the pressure-bearing part and the clamping pressure-bearing part of this utility model are closer to the center of gravity of the pull body, and the distribution of each structure is more reasonable. When the puller pulls the pull body, the pull body does not tilt outwards relative to the zipper. The structural improvement enhances the smoothness of pulling this utility model. At the same time, this design also prevents the rivet posts of the pressure-bearing part and the clamping pressure-bearing part from protruding excessively, which is more in line with the pursuit of the invisibility of the concealed zipper pull.

[0014] Secondly, the design of the fastener prevents the riveting equipment from getting too close to or contacting the pulling member during riveting. Instead, it rivets the pressure-bearing part of the fastener, avoiding machining marks (such as indentations or scratches) on the pulling member during the riveting operation. This makes it easier for this invention to be applied to high-end products with strict requirements on product appearance. At the same time, it achieves the effect of suspending the pulling member at any angle. The recessed design of the pressure-bearing part and the riveting post also increases the rotation range of the pulling member.

[0015] Furthermore, since this utility model is designed as a pressure-bearing part with a relatively large volume for holding the riveting column, rather than a connecting shaft part with a relatively small volume for holding the traction member, a relatively large riveting part can be provided, which is convenient for riveting processing and not easy to break. As a result, the installation of the traction member is more stable and not easy to fall off.

[0016] Finally, in this invention, only the rear bearing part of the fastener is riveted and secured, while the front pressure part is not locked, which gives the pressure part a small elastic deformation effect, allowing it to adapt to more sizes of connecting shafts.

[0017] Because the design of the pull element position in concealed zipper products is quite diverse, this utility model includes, but is not limited to, the following three basic design schemes:

[0018] 1. If the chain channel and the pulling member are located on the same side, then the fastener is set as one and installed on the outer top surface of the chain splitting boss, and the outer top surface of the chain splitting boss protrudes to form at least one riveting post.

[0019] 2. If the chain channel is opposite to the pulling member, then the fastener is set as one and installed on the second plate surface, and the second plate surface protrudes to form at least one of the riveting posts.

[0020] 3. If the product is designed to be double-sided, then the fasteners are set as two and respectively installed on the outer top surface and the second plate surface of the chain boss. The outer top surface and the second plate surface of the chain boss respectively protrude to form at least one of the riveting posts.

[0021] In actual production, the tensioning component can be made of rigid material or flexible material.

[0022] When the pulling member is made of rigid material, the pulling member, fastener, and chain boss should be controlled to have a transition fit, that is, the pulling member can be suspended at will without external force, and the pulling member can rotate when external force is applied.

[0023] Considering the need for precise manufacturing dimensions to achieve a smooth transition between rigid materials, the tensioning component is preferably a flexible resin or rubber component capable of elastic deformation. Using a flexible tensioning component allows for a relatively relaxed range in limiting the clamping force on the end fasteners while ensuring rotation, thus reducing the precision requirements of this invention.

[0024] Alternatively, the tensioning member can be made entirely of a rigid material (such as zinc alloy), with a flexible rubber ring that can produce a certain elastic deformation only on the connecting shaft.

[0025] Preferably, considering that the rotating shaft of the pulling component is a critical part, in actual production, if a fully rubber pulling component is used, care should be taken to avoid designing the injection port on the rotating shaft. It should be designed on the outside of the corresponding rotating shaft of the fully rubber pulling component.

[0026] The fastener is made of rigid metal, is separate from the pull body, and the pressure part is not locked, thus having a slight elastic deformation effect.

[0027] Preferably, the outer top surface and / or second plate surface of the chain boss on which the fastener is installed are provided with an inner recessed groove formed inward into the pull body, the rivet post is provided outside the groove opening of the inner recessed groove, and the pressure bearing part is placed in the inner recessed groove;

[0028] The inner groove makes the pressure-bearing part closer to the interior of the pull body than the rotation axis of the connecting shaft.

[0029] Preferably, the outer top surface and / or second plate surface of the chain boss on which the fastener is installed are provided with an outer support platform that protrudes outward from the pull body. The top surface of the outer support platform supports the connecting shaft portion, and the outer support platform and the pressure application portion cooperate to clamp the connecting shaft portion.

[0030] The outer support platform makes the overall pressure-bearing part closer to the interior of the pull body than the rotation axis of the connecting shaft. The outer support platform and the inner sinker cooperate with each other at different heights, making the structure of this utility model more compact and concentrated.

[0031] Preferably, the outer surface of the pull body is provided with an inner recessed surface, which is closer to the interior of the pull body than the outer support platform, and part of the inner recessed surface continues to be recessed into the interior of the pull body to form the inner recessed groove;

[0032] The rivet post is located on the inner recessed surface. The rivet post, which is deformed by riveting, is closer to the interior of the pull body than the rotation axis of the connecting shaft. This further reduces the outward convex height of the rivet post and increases the rotation range of the pull member. The rotation angle of the pull member is ≥180°.

[0033] The pull body is provided with the inner recessed groove on the rear side of the outer support. Considering that the fastener may be slightly deformed after riveting, that is, the pressure part may be slightly upturned. Long-term opening and closing of the zipper may also cause the pressure part to deform and upturn, thus affecting the clamping effect of the pressure part on the connecting shaft. Therefore, preferably, the front side of the outer support is provided with a slot formed by recessing into the pull body.

[0034] The first end of the pressure-applying part of the U-shaped or C-shaped structure extends outward from the opening to form the pressure-bearing part, and the second end is inserted into the slot. The second end, which is locked in the slot, cannot be easily removed from the slot. Therefore, it can prevent the pressure-applying part from deforming upward to a certain extent and reduce the adverse effect of the long-term pulling of the tensioning member on the clamping effect of the pressure-applying part.

[0035] Preferably, the bottom of the inner sinking trough has a protrusion. When the pressure-bearing part is placed in the inner sinking trough before riveting, the protrusion abuts against the pressure-bearing part so that its bottom surface is suspended and does not contact the bottom of the trough. This provides space for the pressure-bearing part to bend and deform towards the bottom of the trough during riveting, and avoids rigid collision between the fastener and the bottom of the trough.

[0036] The pressure-bearing part has a notch that fits the protrusion. The protrusion abuts against the notch. The notch can cooperate with the protrusion to achieve the above-mentioned suspended design. It also has the function of pre-positioning the fastener before the riveting process to prevent the fastener from sliding or shifting during riveting.

[0037] Preferably, the top front of the split chain boss is suspended above the chain connection channel. The split chain boss with an outer support and a slot places the outer support and the slot on the top surface of the suspended top. The outer support and the slot do not have a design requirement to be close to the inside of the pull body. Designing the bottom of both as part of the chain connection channel can make the structure of this utility model compact and help reduce the size of this utility model.

[0038] Preferably, the top surface of the outer support is a recessed arc surface, which increases the frictional contact area between the outer support and the connecting shaft, and supports the rotation of the connecting shaft. Auxiliary platforms are provided on both sides of the outer support, and the flat top surface of the auxiliary platform is flush with the lowest point of the recessed top surface, which facilitates the quick and easy placement of the connecting shaft (i.e., the pulling part) during assembly, and is beneficial to the accuracy and efficiency of assembly.

[0039] Preferably, the outer support platform located on the chain splitting boss is further away from the pull body relative to the side wing plate, making it easier for the chain teeth to engage with the Y-shaped opening.

[0040] Preferably, each inner sink groove is provided with at least two riveting posts distributed on both sides of the groove opening. The riveting posts distributed on both sides are bent towards the middle by riveting, thereby clamping and fixing them to the pressure-bearing part of the inner sink groove. The riveting and fastening effect on both sides is better, and the unilateral force is avoided during riveting of this utility model. Attached Figure Description

[0071] Example 1

[0072] like Figures 1-4 and Figure 13 As shown, a riveted concealed zipper includes a zipper body 1 and a pulling member 3 for moving the zipper body 1. The pulling member 3 includes a connecting shaft portion 301 for connecting with the zipper body 1. In this embodiment, the pulling member 3 is made entirely of zinc alloy, with a rubber ring 302 only covering the connecting shaft portion 301.

[0073] The pull body 1 includes a base plate portion having a first plate surface 101 and a second plate surface 102. The first plate surface 101 protrudes outward to form a chain splitting boss 103. The left and right sides of the first plate surface 101 extend upward to form two symmetrical side wing plates 104. The tops of the two side wing plates 104 extend in a direction close to each other but do not contact each other or the chain splitting boss 103, forming a Y-shaped opening for the chain teeth to be engaged. The space formed by the two side wing plates 104 together forms a Y-shaped chain engaging channel 105 under the separation of the chain splitting boss 103.

[0074] The riveted concealed zipper also includes a fastener 2, each of the fasteners 2 having a pressure-bearing part 201 and a pressure-applying part 202. The pressure-applying part 202 is a U-shaped or C-shaped structure with an opening, and the pressure-bearing part 201 is formed by extending from one end of the pressure-applying part 202 in a direction other than the opening.

[0075] The fastener 2 is installed on the outer top surface of the chain boss 103. The fastener 2 is installed with its opening facing the outer surface of the pull body 1. The connecting shaft portion 301 of the pulling member 3 is placed in the opening of the pressure application portion 202.

[0076] The pull body 1 has at least one outwardly protruding rivet post 106 at the position corresponding to the pressure-bearing part 201. That is, the outer top surface of the chain-splitting boss 103 protrudes to form at least one rivet post 106. By riveting the rivet post 106, it deforms and clamps the pressure-bearing part 201, thereby fixing the fastener 2 to the pull body 1. The connecting shaft part 301 is sandwiched between the pressure-applying part 202 and the outer surface of the pull body 1 to form a rotatable connection. Under the pressure of the pressure-applying part 202, the connecting shaft part 301 contacts the pressure-applying part 202 and the outer surface of the pull body 1 and there is friction. This friction allows the pulling member 3 to rotate to any angle and stop. In this embodiment, the chain-joining channel 105 and the pulling member 3 are located on the same side.

[0077] After installation, the pressure-bearing part 201 is closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301. The rotation axis of the pressure-bearing part 201 and the rotation axis of the connecting shaft part 301 are not on the same horizontal plane (the figure shows the horizontal plane where the rotation axis is located).

[0078] In this embodiment, the outer top surface of the chain boss 103 on which the fastener 2 is installed is provided with an inner recess 107 formed by recessing into the pull body 1. The rivet post 106 is provided outside the groove of the inner recess 107, and the pressure bearing part 201 is placed in the inner recess 107.

[0079] The inner groove 107 makes the pressure-bearing part 201 closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301.

[0080] In this embodiment, the outer top surface of the chain boss 103 on which the fastener 2 is installed is provided with an outer support platform 108 protruding in a direction other than the pull body 1. The top surface of the outer support platform 108 supports the connecting shaft portion 301. The outer support platform 108 and the pressure application portion 202 cooperate to clamp the connecting shaft portion 301.

[0081] The outer support platform 108 makes the pressure-bearing part 201 closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301. The outer support platform 108 and the inner sink 107 work together at different heights, making the structure of this embodiment more compact and concentrated.

[0082] In this embodiment, each inner sink 107 is provided with two riveting posts 106 distributed on both sides of the sink opening. The riveting posts 106 distributed on both sides are bent towards the middle by riveting, and then fixedly placed in the pressure-bearing part 201 of the inner sink 107. The riveting and fastening effect on both sides is better, and the unilateral force is avoided during riveting in this embodiment.

[0083] In this embodiment, the outer surface of the pull body 1 (i.e. the outer top surface of the chain boss 103) is provided with an inner recessed surface 109. The inner recessed surface 109 is closer to the interior of the pull body 1 than the outer support platform 108. Part of the inner recessed surface 109 continues to be recessed into the interior of the pull body 1 to form the inner recessed groove 107.

[0084] The riveting post 106 is disposed on the inner recessed surface 109. The riveting post 106, which is deformed by riveting, is closer to the interior of the pull body 1 than the rotation axis of the connecting shaft 301, further reducing the outward protrusion height of the riveting post 106 and increasing the rotation range of the pulling member 3. The rotation angle of the pulling member 3 is ≥180°.

[0085] The pull body 1 (i.e., the chain boss 103) is provided with the inner recess 107 on the rear side of the outer support 108. Considering that the fastener 2 may be slightly deformed after riveting, that is, the pressure part 202 may be slightly upturned. The long-term opening and closing of the zipper may also cause the pressure part 202 to deform and upturn, thereby affecting the clamping effect of the pressure part 202 on the connecting shaft 301. Therefore, in this embodiment, the front side of the outer support 108 is provided with a slot 1010 formed by recessing into the pull body 1.

[0086] The first end of the U-shaped or C-shaped pressure-applying part 202 extends outward from the opening to form the pressure-bearing part 201. The second end is inserted into the slot 1010. The second end, which is locked in the slot 1010, cannot easily come out of the slot 1010. Therefore, it can prevent the pressure-applying part 202 from warping or deforming to a certain extent, and reduce the adverse effect of the long-term pulling of the pulling member 3 on the clamping effect of the pressure-applying part 202.

[0087] In this embodiment, the bottom of the inner sink 107 has a protrusion 107a. When the pressure-bearing part 201 is placed in the inner sink 107 before riveting, the protrusion 107a abuts against the pressure-bearing part 201 so that its bottom surface is suspended and does not contact the bottom of the sink. This provides space for the pressure-bearing part 201 to bend and deform towards the bottom of the sink during riveting, and avoids rigid collision between the fastener 2 and the bottom of the sink.

[0088] The pressure-bearing part 201 has a notch 201a that is adapted to the protrusion 107a. The protrusion 107a abuts against the notch 201a. The notch 201a can cooperate with the protrusion 107a to realize the above-mentioned suspended design. At the same time, it also has the function of pre-positioning the fastener 2 before the riveting process to avoid the fastener 2 from sliding and shifting during riveting.

[0089] In this embodiment, the top front of the splitting boss 103 is suspended above the connecting channel 105. The splitting boss 103, which is provided with an outer support 108 and a slot 1010, places the outer support 108 and the slot 1010 on the top surface of the suspended top. The outer support 108 and the slot 1010 do not have the design requirement of sinking close to the inside of the pull body 1. The bottom of the two are designed as part of the connecting channel 105, which can make the structure of this embodiment compact and help reduce the volume of this embodiment.

[0090] In this embodiment, the top surface of the outer support platform 108 is a recessed arc surface, which increases the frictional contact area between the outer support platform 108 and the connecting shaft 301, and supports the rotation of the connecting shaft 301. The outer support platform 108 is provided with auxiliary platforms 1011 on both sides. The flat top surface of the auxiliary platform 1011 is flush with the lowest point of the recessed top surface, which facilitates the quick and easy placement of the connecting shaft 301 (i.e., the tensioning member 3) during assembly in this embodiment, and is beneficial to the accuracy and efficiency of assembly.

[0091] In this embodiment, the outer support platform 108 provided on the chain branch boss 103 is further away from the pull body 1 relative to the side wing plate 104, which facilitates the chain teeth to engage with the Y-shaped opening.

[0092] Example 2

[0093] like Figures 5-8 and Figure 13 As shown, a riveted concealed zipper pull includes a pull body 1 and a pulling member 3 (resin zipper pull) for moving the pull body 1. The pulling member 3 includes a connecting shaft portion 301 for forming a connection with the pull body 1.

[0094] The pull body 1 includes a base plate portion having a first plate surface 101 and a second plate surface 102.

[0095] The first plate surface 101 protrudes outward to form a chain splitting boss 103. The left and right sides of the first plate surface 101 extend upward to form two symmetrical side wing plates 104. The tops of the two side wing plates 104 extend in a direction close to each other but do not contact each other or the chain splitting boss 103, forming a Y-shaped opening for the chain teeth to be inserted. The space formed by the two side wing plates 104 together forms a Y-shaped chain closing channel 105 under the separation of the chain splitting boss 103.

[0096] The riveted concealed zipper also includes a fastener 2, each of the fasteners 2 having a pressure-bearing part 201 and a pressure-applying part 202. The pressure-applying part 202 is a U-shaped or C-shaped structure with an opening, and the pressure-bearing part 201 is formed by extending from one end of the pressure-applying part 202 in a direction other than the opening.

[0097] The fastener 2 is installed on the second plate surface 102 with its opening facing the outer surface of the pull body 1, and the connecting shaft portion 301 of the pulling member 3 is placed in the opening of the pressure application portion 202.

[0098] The pull body 1 has at least one outwardly protruding rivet post 106 at the position corresponding to the pressure-bearing part 201. That is, the second plate surface 102 protrudes to form at least one rivet post 106. By riveting the rivet post 106, it is deformed and clamps the pressure-bearing part 201, thereby fixing the fastener 2 to the pull body 1. The connecting shaft part 301 is clamped between the pressure-applying part 202 and the outer surface of the pull body 1 to form a rotatable connection. Under the pressure of the pressure-applying part 202, the connecting shaft part 301 contacts the pressure-applying part 202 and the outer surface of the pull body 1 and there is friction. This friction allows the pulling member 3 to rotate to any angle and stop. In this embodiment, the chain connection channel 105 is opposite to the pulling member 3.

[0099] After installation, the pressure-bearing part 201 is closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301. The rotation axis of the pressure-bearing part 201 and the rotation axis of the connecting shaft part 301 are not on the same horizontal plane (the figure shows the horizontal plane where the rotation axis is located).

[0100] In this embodiment, the second plate surface 102 on which the fastener 2 is installed is provided with an inner recess 107 formed by recessing into the pull body 1. The rivet post 106 is provided outside the groove of the inner recess 107, and the pressure bearing part 201 is placed in the inner recess 107.

[0101] The inner groove 107 makes the pressure-bearing part 201 closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301.

[0102] In this embodiment, the second plate surface 102 on which the fastener 2 is installed is provided with an outer support platform 108 protruding in a direction other than the pull body 1. The top surface of the outer support platform 108 supports the connecting shaft portion 301. The outer support platform 108 and the pressure application portion 202 cooperate to clamp the connecting shaft portion 301.

[0103] The outer support platform 108 makes the pressure-bearing part 201 closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301. The outer support platform 108 and the inner sink 107 work together at different heights, making the structure of this embodiment more compact and concentrated.

[0104] In this embodiment, each inner sink 107 is provided with two riveting posts 106 distributed on both sides of the sink opening. The riveting posts 106 distributed on both sides are bent towards the middle by riveting, and then fixedly placed in the pressure-bearing part 201 of the inner sink 107. The riveting and fastening effect on both sides is better, and the unilateral force is avoided during riveting in this embodiment.

[0105] In this embodiment, the outer surface of the pull body 1 (i.e. the second plate surface 102) is provided with an inner recessed surface 109. The inner recessed surface 109 is closer to the interior of the pull body 1 than the outer support platform 108. Part of the inner recessed surface 109 continues to be recessed into the interior of the pull body 1 to form the inner recessed groove 107.

[0106] The riveting post 106 is disposed on the inner recessed surface 109. The riveting post 106, which is deformed by riveting, is closer to the interior of the pull body 1 than the rotation axis of the connecting shaft 301, further reducing the outward protrusion height of the riveting post 106 and increasing the rotation range of the pulling member 3. The rotation angle of the pulling member 3 is ≥180°.

[0107] The pull body 1 (i.e. the second plate surface 102) is provided with the inner recess 107 on the rear side of the outer support platform 108. Considering that the fastener 2 may be slightly deformed after riveting, that is, the pressure part 202 may be slightly upturned. The long-term opening and closing of the zipper may also cause the pressure part 202 to deform and upturn, thereby affecting the clamping effect of the pressure part 202 on the connecting shaft part 301. Therefore, in this embodiment, the front side of the outer support platform 108 is provided with a slot 1010 formed by recessing into the pull body 1.

[0108] The first end of the U-shaped or C-shaped pressure-applying part 202 extends outward from the opening to form the pressure-bearing part 201. The second end is inserted into the slot 1010. The second end, which is locked in the slot 1010, cannot easily come out of the slot 1010. Therefore, it can prevent the pressure-applying part 202 from warping or deforming to a certain extent, and reduce the adverse effect of the long-term pulling of the pulling member 3 on the clamping effect of the pressure-applying part 202.

[0109] In this embodiment, the bottom of the inner sink 107 has a protrusion 107a. When the pressure-bearing part 201 is placed in the inner sink 107 before riveting, the protrusion 107a abuts against the pressure-bearing part 201 so that its bottom surface is suspended and does not contact the bottom of the sink. This provides space for the pressure-bearing part 201 to bend and deform towards the bottom of the sink during riveting, and avoids rigid collision between the fastener 2 and the bottom of the sink.

[0110] The pressure-bearing part 201 has a notch 201a that is adapted to the protrusion 107a. The protrusion 107a abuts against the notch 201a. The notch 201a can cooperate with the protrusion 107a to realize the above-mentioned suspended design. At the same time, it also has the function of pre-positioning the fastener 2 before the riveting process to avoid the fastener 2 from sliding and shifting during riveting.

[0111] In this embodiment, the top front of the split chain boss 103 is suspended above the chain convergence channel 105.

[0112] In this embodiment, the top surface of the outer support platform 108 is a recessed arc surface, which increases the frictional contact area between the outer support platform 108 and the connecting shaft 301, and supports the rotation of the connecting shaft 301. The outer support platform 108 is provided with auxiliary platforms 1011 on both sides. The flat top surface of the auxiliary platform 1011 is flush with the lowest point of the recessed top surface, which facilitates the quick and easy placement of the connecting shaft 301 (i.e., the tensioning member 3) during assembly in this embodiment, and is beneficial to the accuracy and efficiency of assembly.

[0113] Example 3

[0114] like Figures 9-12 and Figure 13 As shown, a riveted concealed zipper pull includes a pull body 1 and a pulling member 3 (resin zipper pull) for moving the pull body 1. The pulling member 3 includes a connecting shaft portion 301 for forming a connection with the pull body 1.

[0115] The pull body 1 includes a base plate portion having a first plate surface 101 and a second plate surface 102.

[0116] The first plate surface 101 protrudes outward to form a chain splitting boss 103. The left and right sides of the first plate surface 101 extend upward to form two symmetrical side wing plates 104. The tops of the two side wing plates 104 extend in a direction close to each other but do not contact each other or the chain splitting boss 103, forming a Y-shaped opening for the chain teeth to be inserted. The space formed by the two side wing plates 104 together forms a Y-shaped chain closing channel 105 under the separation of the chain splitting boss 103.

[0117] The riveted concealed zipper also includes two fasteners 2, each of which has a pressure-bearing part 201 and a pressure-applying part 202. The pressure-applying part 202 is a U-shaped or C-shaped structure with an opening, and the pressure-bearing part 201 is formed by extending from one end of the pressure-applying part 202 in a direction other than the opening.

[0118] The two fasteners 2 are respectively installed on the outer top surface of the chain boss 103 and the second plate surface 102. The fasteners 2 are installed with their openings facing the outer surface of the pull body 1. The connecting shaft portion 301 of the pulling member 3 is placed in the opening of the pressure application portion 202.

[0119] The pull body 1 is provided with at least one outwardly protruding riveting post 106 at the position corresponding to the pressure-bearing part 201. That is, the outer top surface of the chain boss 103 and the second plate surface 102 respectively protrude to form at least one riveting post 106. By riveting the riveting post 106, it deforms and clamps the pressure-bearing part 201, thereby fixing the fastener 2 to the pull body 1. The connecting shaft part 301 is clamped between the pressure-applying part 202 and the outer surface of the pull body 1 to form a rotatable connection. Under the pressure of the pressure-applying part 202, the connecting shaft part 301 contacts the pressure-applying part 202 and the outer surface of the pull body 1 and there is friction. This friction allows the pulling member 3 to rotate to any angle and stop. This embodiment is designed to be pulled from both sides.

[0120] After installation, the pressure-bearing part 201 is closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301. The rotation axis of the pressure-bearing part 201 and the rotation axis of the connecting shaft part 301 are not on the same horizontal plane (the figure shows the horizontal plane where the rotation axis is located).

[0121] In this embodiment, the outer top surface and the second plate surface 102 of the chain boss 103 on which the fastener 2 is installed are respectively provided with inner recesses 107 formed by recesses into the pull body 1. The rivet post 106 is provided outside the groove of the inner recess 107, and the pressure bearing part 201 is placed in the inner recess 107.

[0122] The inner groove 107 makes the pressure-bearing part 201 closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301.

[0123] In this embodiment, the outer top surface of the chain boss 103 and the second plate surface 102 of the fastener 2 are respectively provided with an outer support platform 108 protruding in a direction other than the pull body 1. The top surface of the outer support platform 108 supports the connecting shaft portion 301. The outer support platform 108 and the pressure application portion 202 cooperate to clamp the connecting shaft portion 301.

[0124] The outer support platform 108 makes the pressure-bearing part 201 closer to the interior of the pull body 1 than the rotation axis of the connecting shaft part 301. The outer support platform 108 and the inner sink 107 work together at different heights, making the structure of this embodiment more compact and concentrated.

[0125] In this embodiment, each inner sink 107 is provided with two riveting posts 106 distributed on both sides of the sink opening. The riveting posts 106 distributed on both sides are bent towards the middle by riveting, and then fixedly placed in the pressure-bearing part 201 of the inner sink 107. The riveting and fastening effect on both sides is better, and the unilateral force is avoided during riveting in this embodiment.

[0126] In this embodiment, the outer surface of the pull body 1 (i.e. the outer top surface of the chain boss 103 and the second plate surface 102) is provided with an inner recessed surface 109. The inner recessed surface 109 is closer to the interior of the pull body 1 than the outer support platform 108, and part of the inner recessed surface 109 continues to be recessed into the interior of the pull body 1 to form the inner recessed groove 107.

[0127] The riveting post 106 is disposed on the inner recessed surface 109. The riveting post 106, which is deformed by riveting, is closer to the interior of the pull body 1 than the rotation axis of the connecting shaft 301, further reducing the outward protrusion height of the riveting post 106 and increasing the rotation range of the pulling member 3. The rotation angle of the pulling member 3 is ≥180°.

[0128] The pull body 1 (chain boss 103 and second plate surface 102) is provided with the inner recess 107 on the rear side of the outer support 108. Considering that the fastener 2 may be slightly deformed after riveting, that is, the pressure part 202 may be slightly upturned. The long-term opening and closing of the zipper may also cause the pressure part 202 to deform and upturn, thereby affecting the clamping effect of the pressure part 202 on the connecting shaft 301. Therefore, in this embodiment, the front side of the outer support 108 is provided with a slot 1010 formed by recessing into the pull body 1.

[0129] The first end of the U-shaped or C-shaped pressure-applying part 202 extends outward from the opening to form the pressure-bearing part 201. The second end is inserted into the slot 1010. The second end, which is locked in the slot 1010, cannot easily come out of the slot 1010. Therefore, it can prevent the pressure-applying part 202 from warping or deforming to a certain extent, and reduce the adverse effect of the long-term pulling of the pulling member 3 on the clamping effect of the pressure-applying part 202.

[0130] In this embodiment, the bottom of the inner sink 107 has a protrusion 107a. When the pressure-bearing part 201 is placed in the inner sink 107 before riveting, the protrusion 107a abuts against the pressure-bearing part 201 so that its bottom surface is suspended and does not contact the bottom of the sink. This provides space for the pressure-bearing part 201 to bend and deform towards the bottom of the sink during riveting, and avoids rigid collision between the fastener 2 and the bottom of the sink.

[0131] The pressure-bearing part 201 has a notch 201a that is adapted to the protrusion 107a. The protrusion 107a abuts against the notch 201a. The notch 201a can cooperate with the protrusion 107a to realize the above-mentioned suspended design. At the same time, it also has the function of pre-positioning the fastener 2 before the riveting process to avoid the fastener 2 from sliding and shifting during riveting.

[0132] In this embodiment, the top front of the splitting boss 103 is suspended above the connecting channel 105. The splitting boss 103, which is provided with an outer support 108 and a slot 1010, places the outer support 108 and the slot 1010 on the top surface of the suspended top. The outer support 108 and the slot 1010 do not have a design requirement to be close to the interior of the pull body 1. Designing the bottom of both as part of the connecting channel 105 can make the structure of this embodiment compact and help reduce the volume of this embodiment.

[0133] In this embodiment, the top surface of the outer support platform 108 is a recessed arc surface, which increases the frictional contact area between the outer support platform 108 and the connecting shaft 301, and supports the rotation of the connecting shaft 301. The outer support platform 108 is provided with auxiliary platforms 1011 on both sides. The flat top surface of the auxiliary platform 1011 is flush with the lowest point of the recessed top surface, which facilitates the quick and easy placement of the connecting shaft 301 (i.e., the tensioning member 3) during assembly in this embodiment, and is beneficial to the accuracy and efficiency of assembly.

[0134] In this embodiment, the outer support platform 108 provided on the chain branch boss 103 is further away from the pull body 1 relative to the side wing plate 104, which facilitates the chain teeth to engage with the Y-shaped opening.

[0135] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
