It is worth mentioning that the first sliding block 110 and the second sliding block 120 can be disposed face to face with each other or arranged alternately, but that is merely an example and is not meant to limit the instant disclosure.
More precisely, referring to FIG. 2, FIG. 3, FIG. 5 and FIG. 6, the first sliding portion 11 has a first partition block 111 disposed on the first inner surface 1101 thereof and between two of the first sliding blocks 110 (such as two adjacent first sliding blocks 110), and the second sliding portion 12 has a second partition block 121 disposed on the second inner surface 1201 thereof and between two of the second sliding blocks 120 (such as two adjacent second sliding blocks 120). As shown in FIG. 5, the first partition block 111 and the second partition block 121 are disposed face to face with each other (i.e., the first partition block 111 and the second partition block 121 are facing each other). The height of the first partition block 111 relative to the first inner surface 1101 is larger than the height of each first sliding block 110 relative to the first inner surface 1101, and the height of the second partition block 121 relative to the second inner surface 1201 is larger than the height of each second sliding block 120 relative to the second inner surface 1201.

Some of the first sliding blocks 110 and some of the second sliding blocks 120 are disposed inside the first sliding space 1001, and the other first sliding blocks 110 and the other second sliding blocks 120 are disposed inside the second sliding space 1002.
Referring to FIG. 7, the instant disclosure provides a zipper head assembly structure Z for decreasing frictional resistance comprising a sliding member 1 and a pulling member 2 (such as a pull tab or a pull piece).
First, referring to FIG. 5, FIG. 6 and FIG. 7, the sliding member 1 has a first sliding portion 11, a second sliding portion 12 corresponding to the first sliding portion 11, and a connection portion 13 connected between the first sliding portion 11 and the second sliding portion 12. The first sliding portion 11 has a retaining body 112 and the pulling member 2 has an end portion 20 movably mated with the retaining body 112. The first sliding portion 11 has a first inner surface 1101 and a first outer surface 1102 opposite to the first inner surface 1101, and the first sliding portion 11 has a plurality of first sliding blocks 110 disposed on the first inner surface 1101 thereof and separated from each other by a predetermined distance. The second sliding portion 12 has a second inner surface 1201 and a second outer surface 1202 opposite to the second inner surface 1201, and the second sliding portion 12 has a plurality of second sliding blocks 120 disposed on the second inner surface 1201 thereof and separated from each other by a predetermined distance.
Moreover, referring to FIG. 5, FIG. 6 and FIG. 7, the zipper head assembly structure Z is disposed on a zipper teeth structure 3 (such as a zipper tape or a zipper strip) including a first zipper teeth member 31 (such as a zipper rack or a toothed bar) and a second zipper teeth member 32 mated with each other. The first zipper teeth member 31 includes a first zipper teeth carrier 310 for contacting the first sliding blocks 110 and a plurality of first zipper teeth 311 disposed on the first zipper teeth carrier 310 for contacting the second sliding blocks 120, and the second zipper teeth member 32 includes a second zipper teeth carrier 320 for contacting the first sliding blocks 110 and a plurality of second zipper teeth 321 disposed on the second zipper teeth carrier 320 for contacting the second sliding blocks 120. For example, both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 can be made of waterproof material or any other material having high frictional resistance, but this is merely an example and is not meant to limit the instant disclosure.
More precisely, referring to FIG. 5, FIG. 6 and FIG. 7, both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 are slidably disposed on the first sliding blocks 110, so that both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 are separated from the first inner surface 1101 of the first sliding portion 11 by a first predetermined distance d1. Hence, both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 cannot directly contact the first inner surface 1101 of the first sliding portion 11, so that the frictional resistance between the first zipper teeth carrier 310 (or the second zipper teeth carrier 320) and the first sliding portion 11 is decreased. In addition, both the first zipper teeth 311 and the second zipper teeth 321 are slidably disposed on the second sliding blocks 120, so that both the first zipper teeth 311 and the second zipper teeth 321 are separated from the second inner surface 1201 of the second sliding portion 12 by a second predetermined distance d2. Hence, both the first zipper teeth 311 and the second zipper teeth 321 cannot directly contact the second inner surface 1201 of the second sliding portion 12, so that the frictional resistance between the first zipper teeth 311 (or the second zipper teeth 321) and the second sliding portion 12 is decreased. Therefore, the slideness or the smoothness of the zipper head assembly structure Z sliding on the zipper teeth structure 3 is increased.
In conclusion, when both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 are slidably disposed on the first sliding blocks 110, both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 are separated from the first inner surface 1101 of the first sliding portion 11 by a first predetermined distance d1, so that both the first zipper teeth carrier 310 and the second zipper teeth carrier 320 cannot directly contact the first inner surface 1101 of the first sliding portion 11 in order to decrease the frictional resistance between the first zipper teeth carrier 310 (or the second zipper teeth carrier 320) and the first sliding portion 11. In addition, when both the first zipper teeth 311 and the second zipper teeth 321 are slidably disposed on the second sliding blocks 120, both the first zipper teeth 311 and the second zipper teeth 321 are separated from the second inner surface 1201 of the second sliding portion 12 by a second predetermined distance d2, so that both the first zipper teeth 311 and the second zipper teeth 321 cannot directly contact the second inner surface 1201 of the second sliding portion 12 in order to decrease the frictional resistance between the first zipper teeth 311 (or the second zipper teeth 321) and the second sliding portion 12. Therefore, the slideness or the smoothness of the zipper head assembly structure Z sliding on the zipper teeth structure 3 is increased.
The aforementioned descriptions merely represent the preferred embodiments of the instant disclosure, without any intention to limit the scope of the instant disclosure which is fully described only within the following claims. Various equivalent changes, alterations or modifications based on the claims of the instant disclosure are all, consequently, viewed as being embraced by the scope of the instant disclosure.
