Abstract

The utility model relates to a structural improvement of zippers, in particular to a structural improvement of zippers able to improve effectively the sewing threads on each zipper tooth so that the sewing threads is not easy to be broken with pulling friction of the zipper head. The zipper in the utility model comprises a pulling head provided on the zieer; wherein the chain comprises a chain belt with a baffle edge and a pair of chain teeth rows carrying a plurality of chain teeth respectively; and the pulling head is provided on the chain teeth rows. The two chain teeth rows are two lines sewed adjacent to the two baffle chains, and vents are formed symmetrically at the top edge of the chain teeth of the two chain teeth rows; and the sewing threads locate inside those vents. Hence, the pulling head is not to have friction with the sewing threads, so as to enhance service life.

Description

The slide fastener improved structure

Technical field

This creation is about a kind of " slide fastener improved structure ", be meant especially and a kind ofly improve at the structure of this sprocket respectively, with can be with the thread of sewing on this sprocket respectively, effectively improve the slide fastener improved structure that poling is not easy to rupture because of the drawing friction of pull head.

Background technology

Current, be dressed in the clothes (for example: jacket or long and short trousers or the like) on the human body, have considerable part can use slide fastener, if these slide fasteners are impaired to some extent, to cause clothes to wear, be enough to know that slide fastener institute's role on clothes is quite important really.

See also known slide fastener 100 illustrated in figures 1 and 2, it comprises a chain 1 and a pull head 2 that is arranged on this chain 1,1 on this chain comprises a pair of rib chain belt 11 and a pair of chain tooth row 12, these are formed with the chain tooth row 12 of most sprockets 121, and by thread 13 and by the adjacent edge of sewing in described two rib chain belts 11, respectively 12 of this chain tooth rows pass the preset channel (figure does not show) of described pull head 2 respectively, so as to reaching upper and lower pulling purpose as shown in Figure 2.

Also see also shown in Figure 1, this respectively this sprocket 121 to chain tooth row 12 is all to be swollen drum type, and these in order to will be respectively these sprocket 121 sewings in the thread 13 of rib chain belt 11, then will inevitably be standing shape, and be easy to be rubbed, and finally cause thread 13 fractures of sewing by the channel inwall of pull head 2.And the defective that these threads 13 are easy to rupture becomes long-term puzzlement people's a difficult problem at all already.

Therefore, this case creator is still to remain to be improved thoughts on the defective of above-mentioned prior art, so just concentrate on studies, design, proposes a kind of reasonable in design and effectively get rid of this creation of its defective finally.

Novel content

[creation purpose]

The main purpose of this creation " slide fastener improved structure " is to make these sewings in respectively the thread of this sprocket can be effectively no longer outstanding, and so as to avoiding the improper friction of pull head when spurring, relatively then makes these thread utmost points be not easy to fracture.

[creation characteristic]

For reaching above-mentioned purpose, this creation provides a kind of slide fastener improved structure, and this slide fastener comprises a chain and a pull head that is arranged on this chain.Chain wherein is to comprise a pair of rib chain belt and a pair of chain tooth row that respectively has most sprockets, this to the chain tooth row by most thread sewings in the adjacent edge of two rib chain belts, and this is to the upper rim of respectively this sprocket of chain tooth row, also be formed with a scarce recess respectively, described thread then is positioned at this scarce recess; Pull head wherein then be arranged at above-mentioned chain this on the chain tooth row.

By described thread is to be positioned at this scarce recess, when pull head this to the chain tooth row on because of pulling upper and lower when mobile, described pull head respectively this thread that will not rub, and so as to promoting the service life of slide fastener.

The specific embodiment

For making your auditor can further understand the feature and the technology contents of this creation, sincerely see also following detailed description about this creation and appended graphic.

See also Fig. 3 to shown in Figure 5, this creation provides a kind of slide fastener improved structure, this slide fastener 300 that sees Fig. 5 is to comprise a chain 3 and a pull head 4 that is arranged on this

chain

3,3 on this chain comprises a pair of rib chain belt 31 and a pair of chain tooth row 32, these are formed with the chain tooth row 32 of most sprockets 321, and by thread 33 and by the adjacent edge of sewing in described two rib chain belts 31, respectively 32 of this chain tooth rows pass the preset channel (figure does not show) of described pull head 4 respectively, so as to reaching upper and lower pulling purpose as shown in Figure 5.

See also shown in Figure 3, described this respectively upper rim of this sprocket 321 to the chain tooth row, be respectively to be formed with a scarce recess 322 symmetrically, making this respectively this sprocket 321 to chain tooth row 32 all is to be the pea shape, please arranging in pairs or groups, it is shown in Figure 4 to consult again, when by thread 33 and with this to chain tooth row 32 sewings in this to the adjacent edge of rib chain belt 31 on the time, respectively this thread 33 is to be positioned at the respectively scarce recess 322 of this sprocket 321, and can be standing shape as not known for another example, so as to the pulling that makes pull head 4 these threads 33 that will not rub, so promote on the effect that these threads 33 just have the utmost point to be not easy to rupture.

[creative feature and advantage]

Aforesaid creation structure, because thread 33 all is positioned at the respectively scarce recess 322 of this sprocket 321, therefore, the upper and lower pulling of described pull head 4 is these threads 33 that will not rub, in other words, respectively this thread 33 of this creation slide fastener 300 is not easy to fracture with the utmost point, so significantly promote with regard to corresponding the service life of described slide fastener.

In sum, a kind of slide fastener improved structure that this creation provided, the thread that really can solve prior art must have the friction that subjects to pull head and the defective that ruptures, belong to a kind of novel creation product in fact with height practical value, enhancement on the tool effect meets the application requirement of novel patent, so file an application according to Patent Law, please know clearly and give examination and grant accurate this case patent, to ensure creator's rights and interests.

Only the above, only be a preferable feasible embodiment of this creation, the interest field that is not so promptly limits to this creation, the equivalent structure that uses this creation specification and graphic content to do such as changes, all reason gives Chen Ming with being contained in the interest field of this creation.
