Abstract
A fastener chain is configured in such a manner that tape folded sections (22) of fastener tapes (20, 20') are folded inward with first tape surfaces inside, and that engagement head sections (32) of rows (30) of elements are disposed so as to protrude to the outside of the tapes from the tape folded sections (22). Element mounting sections (23, 23') of the fastener tapes (20, 20') have first tape regions (24) which are in contact with lower leg sections (34) of the rows (30) of elements, and also have second tape regions (25) which enclose connection sections (35) and upper leg sections (33) of the rows (30) of elements and which expose the first tape surfaces to the outside. The upper and lower leg sections (33, 34) of the rows (30) of elements are sewn by sewing threads (38) to the first tape regions (24) and the second tape regions (25) of the element mounting sections (23, 23'). When left and right rows (30) of elements have been engaged with each other, mutually facing tape side edges (20a, 20a') of the left and right element mounting sections (23, 23') are in contact with each other. As a result, in the fastener chain, the entire rows (30) of elements are stably hidden by the element mounting sections (23, 23') without the use of cover bodies so that the rows (30) of elements cannot be seen from the outside. Thus, the configuration can improve the appearance of the fastener chain and can cause the element mounting sections (23, 23') to appear as three dimensional objects such as beaded edges.

[patent documentation 2] utility model is registered communique No. 3152100
The utility model content
In the existing CONCEAL ZIPPER of above-mentioned patent documentation 1 record, when the continuous chain denture about making meshes, about zipper strip in band bending part close contact each other, and the chain denture is compared with the band bending part about this close contact by private side (inboard) and is located configuration continuously.Therefore, be in engagement about continuous chain denture, covered by the band bending part about mutual close contact, thereby can not see from the outside.
But, with so existing CONCEAL ZIPPER in the situation that such as article coated middle uses such as vehicle seat chair covers, when about zipper strip pullled by seat webbing etc. and when being subject to the horizontal pulling force of mutual departure direction, about the band bending part between can form the gap.Therefore, the continuous chain denture about sometimes is exposed to the outside by this gap, in existing CONCEAL ZIPPER, even about zipper strip to be subject to shielding status that horizontal pulling force also still keeps continuous chain denture be difficulty very.
On the other hand, in the situation of the slide fastener 70 of above-mentioned patent documentation 2 shown in Figure 10, covered the upper shank of continuous chain denture 73 by nappe 74, but the linking part of chain denture 73 there is not coating lid 74 to cover continuously.Therefore, in this slide fastener 70, chain denture 73 parts are exposed and are easily seen from left and right directions (slide fastener width) continuously, exist to make article coated aesthetic property and/or design that slide fastener 70 is installed reduce such problem.
In addition, in this slide fastener 70, because only the central portion of nappe 74 is sewn in continuous chain denture 73 and chain tooth installation portion 72c by fixed yarn 75, so about the side edge part in the outside of nappe 74 be not fixed in continuous chain denture 73, also exist the side edge part of nappe 74 easily to roll such problem.
In the slide fastener as other embodiment record in the above-mentioned patent documentation 2, bonding nappe on the upper shank of continuous chain tooth and linking part go up the covering of shank and linking part coating lid thus.But, in the situation of making such slide fastener, owing to must after continuous chain teeth space is formed on zipper strip, nappe be adhered to this continuous chain tooth by bonding agent, so the manufacturing process of slide fastener is miscellaneous.
