ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a zipper lock assembly for an article, e.g., a trunk, with a zipper having two pull tabs, and more particularly to a zipper lock assembly that allows auto-ejection of the pull tabs and easy resetting in the code number for unlocking.
2. Description of the Related Art
A conventional zipper lock assembly generally includes a casing with a tie rod onto which two pull tabs of a zipper of a trunk or the like are tied up in an overlapped manner. The tie rod with pull tabs tied up thereon is pressed and a follower member is moved inward to a locked position after the number wheels mounted to the casing are turned to a position other than the correct number code position. Nevertheless, it is found that the pull tabs may not be overlapped for locking if they are too short. Removal of the pull tabs from the tie rod is inconvenient, as the user must remove them one by one. The pull tabs might even be stuck on the tie rod.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to provide a zipper lock assembly that allows easy removal and insertion of the two pull tabs of a zipper on an article (e.g., a trunk) to be locked. The pull tabs are ejected outward automatically after the number wheels of the zipper lock assembly are turned to the correct code position and two press members are pressed inward. Resetting of the code number is easily achieved by turning the number wheels while keeping the press members in the pressed position.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
