Description
- 1. Field of the Invention
- The instant disclosure relates to a zipper head structure; more particularly, to a zipper head structure that prevents a pull tab of separating from the zipper.
- 2. Description of Related Art
- In modern clothing, buttons or zippers are often used to secure two pieces of fabric together. Compare to buttons, the zippers are sturdier and easier to use. A conventional zipper comprises a zipper head and a tape. The zipper head works with the tape to allow the pulling action. In years to come, zippers are forecasted to be used widely for clothing and other accessories.
- Please refer to
FIG. 1 , which shows a sectional view for a standard zipper head structure. The zipper head structure comprises a slider body 1 a, a pull-tab 1 b, alocking hook 1 c, and astopper 1 d. The pull-tab 1 b is disposed onto the slider body 1 a. The pull-tab 1 b has ahinge portion 11 b, which is disposed in between anextension 11 a of the slider body 1 a and thestopper 1 d. When the zipper is closed, thehinge portion 11 b of the pull-tab 1 b would move away from theextension 11 a and toward thestopper 1 d, which is disposed across thelocking hook 1 c. Thereby, thestopper 1 d acts to block the pull-tab 1 b from moving unrestrictedly. However, the aforementioned zipper head structure may be more difficult to assemble, involve more manufacturing steps, increase manufacturing cost, waste raw materials, being less user-friendly, etc. - To address the above issues, the inventor proposes the following solution.
- The instant disclosure provides a zipper head structure, which can improve the assembling process for reducing manufacturing effort and cost.
- The disclosed zipper head structure comprises a slider body, a pull-tab, and a locking hook. The slider body has an assembling surface for disposing an extension and a ridge. The extension is disposed at one end of the slider body, wherein the ridge is disposed near the extension. The pull-tab has a holding portion formed at one end thereon. An opening is formed at the opposite end of the pull-tab away from the holding portion. At one end of the pull-tab wherein the opening is formed, a hinge portion is defined. The pull-tab is disposed onto the assembling surface of the slider body. The extension of the slider body is received by the opening of the pull-tab. The hinge portion is disposed in between the ridge and the extension. The locking hook is disposed on the assembling surface of the slider body.
- Based on the above, the zipper head structure of the instant disclosure uses the ridge that formed integrally with the slider body on the assembling surface to confine the hinge portion of the pull-tab in between the extension and the ridge. Thus, the movement of the hinge portion over the assembling surface is controlled accordingly. No stopper is required for the locking hook to restrict the movement of the pull-tab over the slider body. The advantages include reducing the assembling complexity of the zipper head structure, which reduces the manufacturing effort and cost, saves raw material usage, and promotes environmental friendliness, etc.
- In order to further appreciate the characteristics and technical contents of the instant disclosure, references are hereunder made to the detailed descriptions and appended drawings in connection with the instant disclosure.

The zipper head structure comprises aslider body 11, a pull-tab 12, and alocking hook 13. Theslider body 11 has an assemblingsurface 114, which has anextension 111 and aridge 112 formed thereon. Theextension 111 is formed at one end of theslider body 11, and theridge 112 is formed near theextension 111. The pull-tab 12 has aholding portion 121 formed on one end thereof and anopening 122 formed on an opposite end. Ahinge portion 123 is defined in between theopening 122 and corresponding end of the pull-tab 12. Thehinge portion 123 is opposite of theholding portion 121. The pull-tab 12 is disposed on the assemblingsurface 114 of theslider body 11. Theextension 111 of theslider body 11 is received by the opening 122 of the pull-tab 12. Thehinge portion 123 is disposed in between theridge 112 and theextension 111. Thelocking hook 13 has abase portion 131, which is disposed over thehinge portion 123. Thelocking hook 13 itself is secured onto the assemblingsurface 114 of theslider body 11. - The
slider body 11 further comprises aslot 113 projected thru theslider body 11 and a joiningportion 115 formed on theslider body 11. Theslot 113 is formed on one end of theslider body 11 opposite of the joiningportion 115. The joiningportion 115 extends from the assemblingsurface 114 to the opposite face (not labeled) of theslider body 11. - A
hooking portion 132 is formed by bending one end of thebase portion 131 of thelocking hook 13. Afixing portion 133 is formed by bending another end of thebase portion 131. Thehooking portion 132 of thelocking hook 13 runs thru theslot 113 of theslider body 11, and thefixing portion 133 is secured to the joiningportion 115 of theslider body 11. - Notably, the joining
portion 115 of theslider body 11 is concaved, such that thefixing portion 133 of thelocking hook 13 can fit to the joiningportion 115 for securing to theslider body 11. - In addition, a
mouth 134 is formed in between thebase portion 131 and thehooking portion 132 of thelocking hook 13. Theextension 111 of theslider body 11 projects thru themouth 134 of the lockinghook 13. Theextension 111 of theslider body 11 abuts one side of themouth 134, such that when closing the zipper (not shown), the hookingportion 132 of the lockinghook 13 is caught by theextension 111 to prevent from disengaging theslot 113 of theslider body 11. - Please refer to
FIGS. 4 and 4A , which show a top view and a sectional view along the cut line A-A for the zipper head structure of the instant disclosure respectively. Please also refer back toFIGS. 2 and 3 in conjunction. For assembling the zipper head structure, theopening 122 of the pull-tab 12 is first aligned to theextension 111 on the assemblingsurface 114 of theslider body 11. Next, the pull-tab 12 is disposed onto the assemblingsurface 114 of theslider body 11, such that theextension 111 of theslider body 11 is within theopening 122 of the pull-tab 12. Then, the hookingportion 132 of the lockinghook 13 is projected thru theslot 113 of theslider body 11. When closing the zipper, the hookingportion 132 of the lockinghook 13 is caught by theextension 111 to prevent from disengaging theslot 113 of theslider body 11. The fixingportion 133 of the lockinghook 13 is secured to theconcaved joining portion 115 of theslider body 11. Finally, thebase portion 131 of the lockinghook 13 is pressed toward the assemblingsurface 114 of theslider body 11, such that the fixingportion 133 of the lockinghook 13 is completely secured to theslider body 11. Once completely secured, no more pressing is required on thebase portion 131 of the lockinghook 13. Thus, the assembling process of the zipper head structure is completed. - In use, when closing the zipper (not shown), the holding
portion 121 of the pull-tab 12 is first pulled upward relative to theslider body 11. Next, thehinge portion 123 disposed in between theextension 111 and theridge 112 and over the assemblingsurface 114 of theslider body 11 is defined as a pivot point. By pulling upward, the pull-tab 12 is rotated, such that the holdingportion 121 is at the same end with the joiningportion 115. As the zipper is being closed by pulling the pull-tab 12, thehinge portion 123 of the pull-tab 12 abuts to theridge 112 of theslider body 11. The shape of theridge 112 is not restricted. Thus, when using the zipper, the integrally formedslider body 11 utilizes theridge 112 on the assemblingsurface 114 to confine the movement of thehinge portion 123 of the pull-tab 12 over the assemblingsurface 114, to keep the pull-tab 12 from separating with theslider body 11. - The disclosed zipper head structure mainly uses the ridge, which is integrally formed with the slider body, to confine the hinge portion of the pull-tab in between the extension and the ridge of the slider body. When pulling the zipper, the ridge of the slider body can effectively confine the movement of the hinge portion over the assembling surface of the slider body. Thereby, the zipper head does not need a stopper to confine the movement of the pull-tab. As a result, the assembling complexity of the zipper head structure is reduced. Accordingly, the manufacturing effort and cost can be saved, along with saving raw material usage, promoting design simplification and environmental friendliness, etc.
- The descriptions illustrated supra set forth simply the preferred embodiment of the instant disclosure; however, the characteristics of the instant disclosure are by no means restricted thereto. All changes, alternations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the instant disclosure delineated by the following claims.
