Describe in detail below in conjunction with accompanying drawing.

Referring to FIG. 2 , it shows a perspective view of a zipper device according to a preferred embodiment of the present invention. In this embodiment, the zipper puller 30 includes a puller part 20, an engaging piece 21, and a slider 22, wherein the slider 22 is slipped on the chain teeth 23, and the sliding of the slider 22 can make both sides The teeth 23 are combined or separated. Both the pull part 20 and the slider 22 are buckled on the connecting piece 21 .

Referring to FIG. 3 , it shows the detailed assembly of the tab portion 20 . The pull part 20 includes a transparent cover 10 , a three-dimensional printing grating plate 13 , two transparent spacers 14 and 15 , and a slider fastener 16 . The above-mentioned transparent cover 10 includes a content space 101 and a notch through which the slider fastener 16 protrudes.

In detail, the transparent cover body 10 is composed of an upper cover 11 and a lower cover 12 with the same outline, wherein the upper cover 11 is recessed with an upper cover groove 111, and the lower cover 12 is recessed with a lower cover groove 121. The cover slot 111 and the lower cover slot 121 jointly define the content space 101 . In addition, the upper cover 11 and the lower cover 12 are respectively provided with an upper cover notch 112 and a lower cover notch 122 , when the upper cover 11 and the lower cover 12 are closed, the two notches 112 and 122 together define the aforementioned slider fastener 16 Protruding notch.

The three-dimensional printed grating plate 13 includes a grating structure 131 and a pattern layer 132 located on a plane side of the grating structure 131 . The three-dimensional printing grating plate is a well-known three-dimensional imaging technology, which mainly utilizes the imaging principle of a cylindrical lens in geometric optics to produce a three-dimensional effect on a specially processed image. According to different design parameters, grating panels with different effects can be designed, such as 3D three-dimensional effect, shape change effect, size change effect, continuous dynamic effect or more than two kinds of effects, etc. In this embodiment, the pattern layer 132 is designed as a trademark pattern containing text.

The transparent spacer 14 is attached to the cylindrical surface of the grating structure 131 , and the other transparent spacer 15 is attached to the pattern layer 132 . The slider buckle 16 includes a built-in section 161 and an exposed section 162, wherein the built-in section 161 is wrapped in the content space 101 of the transparent cover 10, and the exposed section 162 is outward from the built-in section 161 The notches 112 and 122 of the transparent cover 10 are extended.

A ring 164 is formed at the end of the exposed section 162 to be sleeved on the connecting piece 21 (shown in FIG. 2 ). The built-in section 161 also includes a locking shoulder 163 formed at the junction with the exposed section 162, so that the built-in section 161 of the slider fastener 16 is constrained in the transparent cover 10 and will not fall out. .

After the transparent spacers 14 and 15 are placed in the lower cover groove 121 of the formed lower cover 12 in a manner of sandwiching the three-dimensional printing grating plate 13, and the slider fastener 16 is positioned in the lower cover, the The above combination is placed in an upper cover injection molding mold, and the complete handle part 20 is manufactured by injection molding. At this time, the two transparent spacers 14 and 15 and the three-dimensional printing grating plate 13 are located in the content space 101 of the transparent cover 10 together.

In this embodiment, the transparent cover 10 is made of thermoplastic polyurethane (thermoplastic urethanes; TPU), the two transparent spacers 14 and 15 are made of polycarbonate (polycarbonate; PC), and the three-dimensional printing grating plate 13 is made of polyphenylene resin (Poly Ethylene). Terephthalate; PET) material. But of course it is not limited to the embodiments, for example, the transparent spacer can also be made of polymethylmethacrylate (PMMA), and the three-dimensional printed grating plate can also be made of polycarbonate.

In addition, in this embodiment, the cover body (including the upper cover and the lower cover) is specially designed as a transparent cover body with a magnifying glass structure, that is, a convex lens structure, so that the magnified three-dimensional Animated images for a deeper visual experience.

In addition, through the arrangement of two transparent spacers, when the three-dimensional printing grating plate is placed in the cover body injection molding mold, the cover body will not be deformed due to the unavoidable high molding temperature, resulting in the failure of the three-dimensional animation effect. Refer to FIGS. 4A and 4B , which are used to compare the special effects when two additional transparent spacers are provided.

In Fig. 4A, because the three-dimensional printing grating plate is directly in contact with the cover body in design, when the cover body is injection molded, the high temperature generated in the process may damage the pattern layer 432 of the three-dimensional printing grating plate 43, and the grating structure 431 will also be damaged. Like rubbing effect, the lower cover 42 will be deformed toward the concave of the curved surface side of the grating structure 431 . In this way, the special optical structure configuration capable of exerting the stereoscopic effect has been destroyed.

As shown in Fig. 4B, since the transparent spacers 14 and 15 are additionally arranged on both sides of the three-dimensional printing grating plate 13, when the final cover body injection molding is performed, the high temperature of the process will not cause the deformation of the lower cover, and the pattern layer 132 will not be deformed. It will not be damaged by high temperature.

The above-mentioned embodiments are only examples for convenience of description, and the scope of rights claimed by the utility model should be based on the scope of claims in the application, rather than limited to the above-mentioned embodiments.
