Zipper head structure

Abstract

A zipper head structure is disclosed, which includes a slider body, a pull-tab, and a locking hook. The slider body has a protrusion which is formed on the slider body. The pull-tab has a holding portion and an opening. The protrusion is located in the opening of the pull-tab. The locking hook has a base portion which is located over the hinge portion. The locking hook is disposed on the slider body. The base portion has a through hole. A stopper is downwardly formed by one side of the through hole. The hinge portion is disposed between the protrusion and the stopper. Thereby, by utilizing the stopper of the locking hook which is integrally formed, the movement of the hinge portion is effectively confined for preventing the pull-tab from separating with the slider body when pulling the zipper.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]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.[0003]2. Description of Related Art[0004]In general, zippers are basic elements in clothing or accessories. Compare to buttons, the zippers are 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. Recently, zippers has being used commonly for clothing, pants, backpack, and other accessories.[0005]Please refer to FIG. 1, which shows a sectional view for a standard zipper head structure. The zipper head structure comprises a slider body 1a, a pull-tab 2a, a locking hook 3a, and a stopper 4a. The pull-tab 2a is disposed onto the slider body 1a. A hinge portion 21a of the pull-tab 2a is located in back of a protrusion 11a of the slider body 1a, and which is located in front of a stop...

AI Technical Summary

Benefits of technology

[0007]The instant disclosure provides a zipper head structure, which can improve the assembling process for reducing manufacturing effort and cost.

[0009]Based on the above, the zipper head structure of the instant disclosure uses the stopper of the locking hook that is integrately formed to block and confine the movement of the hinge portion. 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, etc.

Problems solved by technology

However, the aforementioned zipper head structure may be more difficult to assemble, involve more manufacturing steps, complex manufacturing process, increase manufacturing cost, etc.
