DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Reference is made to FIGs. 3-9, which show the plug pin set of a zipper of the present invention. The plug pin set is applied to a metallic double open zipper. The plug pin set includes a plug pin 1 and a position pin 2. The shape of the plug pin 1 and the shape f the position pin 2 are complementary and similarly symmetric. The plug pin 1 is a metal piece that is made of metal material. The plug pin 1 has a plug pin body 11 (as shown in FIGs. 4-6). The plug pin body 11 is rectangular. The front side of the plug pin body 11 is an arc. The rear side of the plug pin body 11 is ladder-shaped. The plug pin body 11 has a first long side 12 and a second long side 13. The first long side 12 and the second long side 13 are located on the two opposite sides of the plug pin body 11. In the plug pin body 11, there is a first joint trough 14 that is long.
The first joint trough 14 passes through the second long side 13 and the rear side of the plug pin body 11. One end of the second zipper belt is placed into the first joint trough 14 via the rear side of the plug pin body 11 so that the plug pin I is joined with one end of the second zipper belt.
[00231 On the first long side 12, there is a slanted surface 15 and a first concave trough 16. The slanted surface 15 is adjacent to the front end of the plug pin body 11. The slanted surface 15 extends to another side of the plug pin body 11. Having the slanted surface 15 means that the dimension of the front side of the plug pin body 11 becomes increasingly narrower. The first concave trough 16 is located at the center of the plug pin body 11. The first concave trough 16 is located at the first long side 12 with a limited depth. The dimension of the first concave trough 16 is determined by the punching force and the location of the fastening point. On the first long side 12, there is an embedded trough 17. The embedded trough 17 is adjacent to the rear side of the plug pin body 11.
100241 The position pin 2 is a metal piece that is made of metal material.
The position pin 2 has a position pin body 21 (as shown in FIGs. 7-9). The position pin body 21 is rectangular. The front end of the position pin body 21 is an arc. The rear end of the position pin body 21 is ladder-shaped. The position pin body 21 has a third long side 22 and a fourth long side 23. The third long side 22 and the fourth long side 23 are located at two opposite sides of the position pin body 21. In the position pin body 21, there is a long second joint trough 24. The second joint trough 24 passes through the fourth long side 23 and the rear side of the position pin body 21. One end of the first zipper belt can be placed into the second joint trough 24 via the rear side of the position pin body 21 so that the position pin 2 is joined with one end of the first zipper belt.
100251 On the third long side 22, there is a second concave trough 25.
The second concave trough 25 is located at the center of the position pin body 21. The second concave trough 25 is located at the third long side 22 with a limited depth. The dimension of the second concave trough 25 is determined by the punching force and the location of the fastening point. Another two opposite sides of the position pin body 21 respectively have a blocking point 26. The two blocking points 26 are adjacent to the front side of the position pin body 21 for blocking the convex portion in the zipper head so as to stop the zipper head. The third long side 22 further has a convex block 27. The convex block 27 is adjacent to the rear side of the position pin body 21. The convex block 27 corresponds to the embedded trough 17.
100261 Reference is madeto FIG. 10. The plug pin 1 utilizes the first joint trough 14 so as to join with one end of the second zipper belt 4. The position pin 2 utilizes the second joint trough 24 so as to join with one end of the first zipper belt 3. The plug pin 1 and the position pin 2 are respectively fastened onto the second zipper belt 4 and the first zipper belt 3 by using the punching the fastening points 18, 28. The fastening points 18, 28 are punched and formed on one side or two sides of the plug pin 1 and the position pin 2. In this embodiment, one side of the plug pin I has two fastening points 18, and one side of the position pin 2 has two fastening points 28 so that the plug 1 and the position pin 2 are joined with the second zipper belt 4 and the first zipper belt 3. The plug pin 1 corresponds to the position pin 2.
100271 While the fastening points 18, 28 are being punched and formed, the sides that the plug pin 1 and the position pin 2 are connected (the first long side 12, the third long side 22) are then extruded and protruded due to punching. The present invention utilizes the first concave trough 16 and the second concave trough 25 to cancel the extruding and protruding effect so that the sides that the plug pin 1 and the position pin 2 that are connected is kept in a plane and not distorted. Therefore, the sides that the plug pin 1 and the position pin 2 are connected do not become protruded. Thus, the interference between the first zipper head 5 and the second zipper head 6 can be avoided.
The plug pin I and the position pin 2 can be plugged and lifted smoothly.
100281 The plug pin 1 located at one end of the second zipper belt 4 can be plugged into the sliding trough in the second zipper head 6 via the sliding trough in the first zipper head 5 so that the first zipper head 5 and the second zipper head 6 are assembled on the first zipper belt 3 and the second zipper belt 4. The first zipper belt 3 and the second zipper belt 4 that can be toothed together may be controlled to open or close by pulling the first zipper head 5 and the second zipper head 6 forth and back. When the plug pin 1 and the position pin 2 are closed, the convex block 27 is embedded into the embedded trough 17.
100291 The description above only illustrates specific embodiments and examples of the present invention. The present invention should therefore cover various modifications and variations made to the herein-described structure and operations of the present invention, provided they fall within the scope of the present invention as defined in the following appended claims.
