In the prior art, a patent with an application number of “CN201610105490.0” discloses a slider for a zipper and a zipper. By disposing a pair of claws to tightly grip a rotating shaft of a rubber puller, the effect of arbitrary suspending is achieved. However, in actual production, no matter whatever processing technique is used (such as riveting, which is most commonly used in zipper processing) to achieve the gripping effect of the claws on the rotating shaft of the puller, since the puller and the claws are in direct contact, and a distance between equipment and the puller during processing is extremely close, there may be processing marks (such as pressing marks, scratches, etc.) on the surface of the puller, which is not conducive to applying the slider to high-end products with strict product appearance requirements. Moreover, the slider itself is a tiny part, and as a part of the slider, the claws are smaller in size and so are easy to break during processing.

As shown in
The slider body 1 includes a base portion 102, a guide column 101 is disposed on one side of a middle of a top surface of the base portion 102, a left side and a right side of the base portion 102 are symmetrically provided with a left stopper 103 and a right stopper 104, top ends of the left stopper 103 and the right stopper 104 extend inwardly, a Y-shaped zipper alignment channel is formed in a space enclosed by the left stopper 103 and the right stopper 104 under the separation of the guide column 101, and the zipper alignment channel is opened upwardly for allowing zipper teeth to be clamped into the zipper alignment channel.
The puller includes a rotating shaft disposed at a front end and configured to be connected with the slider body.
The invisible slider in this embodiment further includes an end pressing member 3 installed at a top of the guide column 101, the end pressing member 3 having a pressed part at a front end and a pressing part at a rear end; and a riveting portion 105 is disposed at a position corresponding to the pressed part at the top of the guide column 101, the riveting portion 105 riveting the pressed part at the front end of the end pressing member 3.
The rotating shaft of the puller 2 is sandwiched between the pressing part at the rear end of the end pressing member 3 and the guide column 101 and forms rotating connection, and the rotating shaft of the puller 2 is in contact with the pressing part and the guide column 101 under the pressing of the pressing part, and a frictional force is present between the rotating shaft of the puller 2 and the pressing part and between the rotating shaft of the puller 2 and the guide column 101, the frictional force allowing the puller 2 to rotate to any angle to be suspended.
Firstly, the provision of the end pressing member 3 not only enables the puller 2 to achieve an arbitrary suspending effect, but also enables a riveting device to rivet the end pressing member 3 without being in contact with the puller 2 during riveting, avoiding processing marks (such as pressing marks, scratches, etc.) on the puller 2, which is beneficial for applying the invisible slider in this embodiment to high-end products with strict product appearance requirements.
Secondly, since the end pressing member 3 is riveted and fastened instead of directly riveting and fastening the puller 2 in this embodiment, a relatively large riveting portion 105 can be provided, which is convenient for riveting processing and is not likely to cause breakage.
Finally, only the pressed part located at the front end of the end pressing member 3 is riveted, so that the pressing part located at the rear end is not fastened, thereby the pressing part has a small elastic deformation effect, which can adapt to more sizes of the rotating shaft.
In particular, the puller 2 may be made of a rigid material or a flexible material. When the puller 2 is made of the rigid material, it should be controlled that there is a transition fit between the puller 2 and the end pressing member 3 and between the puller 2 and the guide column 101, i.e., the puller 2 can be arbitrarily suspended without an external force, and the puller 2 can be rotated under the action of the external force. In view of the precise production dimensional requirements required to achieve the transition fit of the rigid material, the puller 2 is preferably made of a flexible elastically deformable material (e.g., rubber, etc.), and the puller 2 in this embodiment is a resin puller. Under the condition of ensuring the puller 2 made of the flexible material to be rotated, the limit of the pressing force of the end pressing member 3 has a relatively loose range, which can reduce the requirement of machining accuracy in this embodiment.
In particular, the end pressing member 3 is made of a rigid metal, and the end pressing member 3 and the slider body 1 are separately disposed, so that the rear end of the end pressing member 3 is not fastened and has a small elastic deformation effect.
In this embodiment, the top of the guide column 101 is provided with a positioning groove 106 which is open and configured to place the rotating shaft of the puller 2, facilitating positioning of the puller 2 before riveting, a connecting hole is formed in a space enclosed by the pressing part of the end pressing member 3 and an open end of the positioning groove 106 at the open end of the positioning groove 106, the rotating shaft of the puller 2 is mounted in the connecting hole to form the rotating connection, and the rotating shaft of the puller 2 is in contact with a hole wall of the connecting hole, and a frictional force is present between the rotating shaft of the puller 2 and the hole wall of the connecting hole, the frictional force allowing the puller 2 to rotate to any angle to be suspended.
In particular, the positioning groove 106 has a downward concave arc-shaped structure, and the pressing part of the end pressing member 3 is a bending arm 301, and the connecting hole is formed in a space enclosed by the bending arm 301 and the open end of the positioning groove 106 at the open end of the positioning groove 106, so that the contact area of the puller 2 with the positioning groove 106 and the end pressing member 3 can be increased to achieve the suspending effect while facilitating the rotation of the puller 2.
In this embodiment, the bending arm 301 serves as an end structure of the end pressing member 3, in actual production, the bending arm 301 can be produced so that its end is precisely connected to the open end of the positioning groove 106, thereby enclosing the connecting hole, however, in view of the possibility of slight deformation of the end pressing member 3 after riveting, i.e. the bending arm 301 may slightly tilt upwards, long-term pulling of the puller 2 may also cause the bending arm 301 to tilt upwards, resulting in a gap between the end of the bending arm 301 and the open end of the positioning groove 106, which affects the clamping effect of the bending arm 301 of the end pressing member 3. Therefore, the top surface of the guide column 101 is provided with a downwardly recessed slot 107, the slot 107 is located at one side of the positioning groove 106, the connecting hole is formed in the space enclosed by the bending arm 301 and the open end of the positioning groove 106 across the open end of the positioning groove 106, and an end of the bending arm 301 is inserted into the slot 107, this design ensures that the bending arm 301 has a sufficient length, even the bending arm 301 slightly tilts upwards, the bending arm 301 and the open end of the positioning groove 106 are still maintained to be enclosed, since there is no need to be connected with the open end of the positioning groove 106, the production accuracy requirements are also reduced to a certain extent, and the design of the slot 107 can prevent the bending arm 301 from being deformed such as tilting upwards, thereby reducing the effect of the long-term pulling of the puller 2 on the clamping effect of the end pressing member 3.
In this embodiment, the top of the guide column 101 is provided with a downwardly recessed pressing member groove 108, the pressed part of the end pressing member 3 is placed in the pressing member groove 108, left and right displacements of the end pressing member 3 are limited by the pressing member groove 108, and the riveting portions 105 are disposed on both sides of a groove opening of the pressing member groove 108, and are mainly used to position the end pressing member 3, preventing the end pressing member 3 from being displaced during riveting, reducing the effect that the end pressing member 3 protrudes outward from the surface of the slider body 1, and making the outer surface of the invisible slider in this embodiment more flat and concise.
More specifically, the top surface of the guide column 101 is provided with a lower groove, a groove bottom of the lower groove protrudes upwardly to form a boss, a top surface of the boss is recessed downwardly to form the positioning groove 106, and the boss divides the lower groove into an upper groove body, which is the pressing member groove 108, and a lower groove body, which is disposed as the slot 107. The structure is simplified and convenient for production and processing.
In this embodiment, the pressing member groove 108 is provided with a blocking protrusion 109, the end pressing member 3 is provided with a clamping opening 302 adapted to the blocking protrusion 109, the clamping opening 302 is clamped to the blocking protrusion 109, and sliding of the end pressing member 3 in the pressing member groove 108 is limited by the blocking protrusion 109, further positioning the end pressing member 3, ensuring that the end pressing member 3 is not displaced when riveted, and meanwhile, when the puller 2 is pulled, the bending arm 301 and the positioning groove 106 are easily subjected to a collision force, as the use time increases, long-term collision may cause the bending arm 301 to be deformed, and the blocking protrusion 109 may share the pulling force, thereby avoiding the problem of deformation caused by multiple collisions of the bending arm 301.
