AI Technical Summary

Benefits of technology

The present invention provides a zipper insertion-pin structure with toothed slits or gradually-shrinking slits at two sides to bite and fasten the tapes of the zipper. This structure can fasten the insertion pins to the tapes without punching the insertion pins, saving some fabrication steps of the conventional technology. Additionally, the insertion pins fasten to the tapes more firmly and are more beautiful than the conventional insertion pins that are punched to form indentations.

Problems solved by technology

The conventional technology needs expensive dedicated machines to punch the insertion pins accurately.
Besides, the punched surfaces of the insertion pins are neither smooth nor beautiful.

Embodiment Construction

[0016]Refer to FIG. 2 and FIG. 3 respectively a perspective view and an exploded view schematically showing a zipper insertion-pin structure according to one embodiment of the present invention.

[0017]The zipper insertion-pin structure of the present invention comprises a first insertion pin 20 and a second insertion pin 22. The first insertion pin 20 has a base 201. An external side of the first insertion pin 20 has a first slit 202 extending to the base 201. The base 201 has a socket 204 at one side opposite to the abovementioned external side. The socket 204 can exactly accommodate the second insertion pin 22. The external side of the socket 204 has an opening 206. The external side of the second insertion pin 22 has a second slit 222. The second insertion pin 22 can be exactly press-fitted into the socket 204 of the base 201 and secured thereinside.

[0018]In one embodiment, the first slit 202 has a plurality of teeth 224 staggered to each other. The protrusions of the teeth 224 on...

Abstract

A zipper insertion-pin structure comprises a first insertion pin and a second insertion pin. The first insertion pin has a first slit on an external side thereof and a base on one side opposite to the external side. The base has a socket. The second insertion pin has a second slit on an external side thereof and can be inserted into the socket. Each of the first slit and the second slit has a plurality of teeth or gradually narrows toward the center thereof. The first insertion pin and the second insertion pin grip the tapes of a zipper with the biting force thereof.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a zipper insertion-pin structure, particularly to a zipper insertion-pin structure able to enhance the biting force to zipper tapes.[0003]2. Description of the Related Art[0004]The conventional zippers may be categorized into nylon zippers, metallic zippers and injection-molded zippers. The insertion pins of nylon zippers and metallic zippers are fastened to tapes after they have been arranged on the tapes. The insertion pins of injection-molded zippers, together with teeth, are directly clamped to tapes in the injection-molding process, applying higher biting force to the tapes.[0005]Refer to FIG. 1 for the conventional insertion-pin structure of nylon zippers and metallic zippers. The conventional insertion-pin structure comprises a first insertion pin 10 and a second insertion pin 12. The first insertion pin 10 is connected with a base 101, and the second insertion pin 12 is inserted ...
