no. 1 example

[0042] If the linear zipper of the present invention is explained, Figures 1 to 7 In the linear slide fastener of the first embodiment shown, its linear slide fastener member 1 is formed by winding polyamide or polyester monofilament into a coil shape. In the linear zip component 1, as in Figures 2 to 6 As shown, a coupling head 10 is formed at one end and a reverse portion 11 is formed at the other end and the two parts are connected with an upper leg 12 and a lower leg 13 to form a coiled zipper member 2 . The coiled zipper member 2 is sewn to the sides of the zipper tape 4 with sewing thread 6 , for example, double loop sewing using two needles and three threads with a center line 18 passing through the inside of the coiled zipper member 2 .

[0043] In the coiled fastener member 2, such as figure 2 As shown in , when the height between the top surface of the upper leg 12 and the bottom surface of the lower leg 13 on the side of the coupling head 10 is assumed to be H1...

[0052] according to Figure 8 The shown linear slide fastener of the second embodiment of the present invention is a concealed type slide fastener having folded portions 22 on the sides of the fastener tape 4, wherein the left and right folded portions 22 abut against each other and have the same design as the above-mentioned coiled fastener member 2. The conditioned upper leg portion 12 is sewn and secured by using the sewing thread 6 as a double loop stitching of the securing thread 5 passing through the recess 14 . In this case, the recess 14 is formed in the leg placed on the outside. This hidden type zipper has the same setting conditions as the above example so that the fixing wire 5 is accommodated in the recess 14 formed in the upper leg 12 so as to be prevented from moving and slipping from the coupling head 10 side. The reverse portion 11 at one end of the coiled zipper member 2 can be formed in a small size so that the entirety of the coiled zipper member 2 can be ...

no. 3 example

[0054] according to Figure 9 The shown linear slide fastener of the third embodiment of the present invention is a linear slide fastener produced by sewing and fixing the zigzag fastener member 3 on the side of the fastener tape 4 using the sewing thread 6 as the double loop sewing of the fixing thread 5 . The zigzag zipper member 2 is provided with the same various setting conditions as those of the above examples and the upper leg portion 12 on the coupling head 10 side is formed with a steep slope and the upper leg portion 12 on the reverse portion 11 side is formed into a steep slope. Form a gentle slope. The center line 18 is inserted between the upper leg 12 and the lower leg 13 of this zigzag zipper member 3 and the recess 14 formed in the upper leg 12 is made by using the sewing thread 6 of the double loop sewing as the fixing thread 5 be fixed.

[0055] The linear zipper member 1 of this embodiment is set under the same setting conditions as the aforementioned cond...

Abstract

The invention intends to provide a linear slide fastener in which a size of a fastener element is reduced thereby saving resources and achieving a smooth sliding of a slider, wherein a concave portion (14) that accommodates a fixing thread (5) for fixing a fastener tape (4) is provided on a top face of an upper leg portion (12) of a coil-like or zigzag-like linear fastener element (1), when dimensions from a bottom face of a lower leg portion (13) up to a top face of the upper leg portion (12) on a side of a coupling head (10), at the concave portion (14) and on a side of an inverted portion (11) are assumed to be H1, H2 and H3 respectively, a setting condition of H1 > H3 > H2 is satisfied and when dimensions from a bottom face of the upper leg portion (12) to a top face of the lower leg portion (13) within a gap portion (16) on the side of the coupling head (10), at a convex portion (15) and on the side of the inverted portion (11) are assumed to be H4, H5 and H6 respectively, a setting condition of H4 > H6 > H5 is satisfied.

Description

field of invention [0001] The present invention relates to a linear slide fastener in which a thermoplastic resin monofilament (thermoplastic resin monofilament) is formed into a slide fastener member having a special shape in a coil shape or a zigzag shape, and the linear slide fastener member is attached to a fastener having various types of sewing threads such as On the side of the zipper tape that secures the thread. Background technique [0002] In the coil-shaped zipper member 102 of the traditional linear zipper disclosed in US3149388, when the coil-shaped zipper member 102 is sewn on the side of the zipper tape 104 with a sewing thread 106 by a sewing machine, in order to protect the sewing thread 106 from being damaged by the sliding slider The concave portion 114 is formed at the central portion of the upper leg portion of the coil-shaped fastener member 102, and as Figure 12 The sewing thread 106 shown in is housed in this recess 114 to be protected. In this coi...
