Abstract

The present invention relates to the improvement of slide fastener made of synthetic resin inventions, it is related to following flexibility height and the good slide fastener made of synthetic resin of zipper engagement property, i.e., in above-mentioned slide fastener made of synthetic resin, when adhering to zipper coil to ribbon, running-on piece is covered along the contralateral surface for the fixed part being in contact with ribbon, and the set mouth line combined with sewing thread is covered on the surface of running-on piece, to make the fixed part of zipper coil by running-on piece and set mouth line in conjunction with and crimp and be attached to ribbon, thus, because the elastic restoring force of the fixed part of zipper coil obtains that chain tooth flexible phenomenon when using zipper can be prevented due to increase, so as to actively prevent the engagement relaxation of chain tooth and the phenomenon that separate.

Description

Slide fastener made of synthetic resin

Technical field

The present invention relates to the improvement of slide fastener made of synthetic resin inventions, relate more specifically to, the inner end along a pair of of ribbon is matched It is equipped with slide fastener made of synthetic resin coil, is knitted to be fixed in such a way that the chain tooth of two sides zipper coil mutually staggers using sewing thread Band, and two sides chain tooth can be made to be combined with each other or isolated slide fastener made of synthetic resin using pull head, when adhering to zipper coil to ribbon, Along the fixed part being in contact with ribbon contralateral surface cover running-on piece, and make cover mouth line in a manner of lid running-on piece surface with Sewing thread combines to fix zipper coil, so that the fixed part of zipper coil is by stable pressure and fixation, thus making Used time is not flexible, as a result, because the meshing state of zipper coil head is not easy to become the isolated zipper for preventing chain tooth due to relaxation.

Background technique

Since the zipper coil of previous slide fastener made of synthetic resin is made of synthetic resin coil line, thus the robustness of chain tooth Deficiency, if also, the fixed part of zipper coil is overlapped in ribbon, and sewed using sewing thread to fix, then zipper motif The fixed part of circle can not be stitched firmly tightly in ribbon, so that there are the following problems: if the fixed part of zipper coil is flexible and draws The case where chain coil is bent, then chain tooth separates frequent occurrence due to relaxation is engaged on head.

Thus, the above problem in order to prevent, it is intended to upper side and bottom surfaces the covering fixing tape of zipper coil come into Row sewing, but since this can make zipper coil become clumsy, so as to cause the flexible as a result, thus not of zipper coil is reduced Convenient for as using the zipper of the clothes of thin cloth or ornaments come using.

Summary of the invention

It solves the problems, such as

The present invention is developed for solving above-mentioned inconvenient.

The means solved the problems, such as

The present invention is overlapped into the fixed part of resin teeth zipper coil in ribbon side end layer, and puts into the inside of zipper coil Core material, thus make the chain tooth of zipper coil to the prominent specific length in the side of ribbon, the fixation using sewing thread to zipper coil Portion and ribbon are sewed, to make zipper coil be attached to the surface of ribbon, and in zipper coil fixed part, with ribbon The contralateral surface being in contact covers the running-on piece formed by the fabric thinner than ribbon, and covers and sew in the outer surface of running-on piece The set mouth line that line combines, so that running-on piece and set mouth line be made to carry out crimping to the fixed part of zipper coil and together with sewing thread It crimps and fixes, and then increase elastic restoring force because authorized pressure acts on the fixed part of zipper coil, thus prevent The phenomenon that only zipper coil is easily bent when using zipper, so as to actively prevent the engagement because of chain tooth from separating due to relaxation Phenomenon.

The effect of invention

As described above, in the present invention, in laminated configuration in the appearance of the fixed part of the zipper coil of one side surface of ribbon Face covers the running-on piece thinner than ribbon, and combines in running-on piece surface covering jacket mouth line with sewing thread, thus running-on piece and The plus-pressure of set mouth line acts on the fixed part of zipper coil together, thus improves the elastic restoring force of fixed part.

Also, covering mouth line has the structure woven in the following manner: if forming ring from ribbon to running-on piece direction Sewing wire loop insertion set mouth line form ring, then be inserted into the inside for being formed by running-on wire loop and next be formed by sewing Wire loop is completed to weave, if the wire loop that makes to sew is from bottom after one end of running-on wire loop is retreated to the sewing wire loop formed for the first time Ring is formed by next sewing wire loop behind top, then has been come inside the sewing thread investment running-on wire loop of next formation At braiding.Therefore, sewing thread and set mouth line are tied, to press the fixed part of zipper ring, so that fixed part is pressed Tightly, and once it is tied, then adheres to zipper coil in a manner of it can not unlock, so that covering mouth line presses zipper together with running-on piece The surface of the fixed part of coil, so that the zipper motif for making the fixed part of zipper coil be under pressure and fix to ribbon direction Circle is fixed without realizing reelingly, and the elasticity for increasing the fixed part of coil form zipper coil improves elastic restoring force, thus Play the role of keeping zipper coil inflexible.

Thus, it actively prevents from being separated because zipper is bent the head for leading to zipper coil engagement relaxation due in use Phenomenon, and obtain following effect: since chain tooth part is thin, thus flexibility becomes abundant, since zipper is not flexible, thus It can get the outstanding zipper of head engagement property.

Fig. 2 is the top view of Fig. 1.

Fig. 3 is the cross-sectional view of Fig. 1.

Specific embodiment

The present invention is that flexibility is high and zipper engages the good slide fastener made of synthetic resin of property, along the side upper side of ribbon 1 The 2 fixed part 2a of slide fastener made of synthetic resin coil of multilayer coil shape, and core material 3 is put into the inside of zipper coil, to make chain tooth It is knitted to after the prominent specific length in ribbon side so that being configured at using the zipper coil that sewing thread 4 is attached to ribbon the part 2b Thus 1 two sides of band are opened and closed chain tooth part by pull head (slider), above-mentioned flexibility is high and zipper engages the good conjunction of property It is characterized in that at resin teeth zipper,

The running-on piece 5 thinner than ribbon is covered to the length direction of ribbon on the surface of the fixed part of zipper coil, in running-on The surface of piece covers two rows of set mouth lines 6, set mouth line 6a, to make set mouth line combine with sewing thread, at this point, covering mouth line to sewing Line 4 is formed by the inside investment set mouth line 6 of sewing wire loop 40 to form running-on wire loop 60a, if throwing to the inside of running-on wire loop Enter next sewing wire loop 40a to keep above-mentioned sewing wire loop 40a prominent, then first sewing wire loop is passed through in one end of running-on wire loop 40 bottom enters the inside of sewing wire loop, and by next sewing wire loop 40a after the upper side for wire loop of sewing Portion forms new running-on wire loop, in the case, so as to put into next formation to the inside of the running-on wire loop newly formed The structure that is repeated of process of sewing wire loop 40b carrys out wired tube mouth line so that set mouth line by crimping running-on piece come with running-on Piece crimps the fixed part of zipper coil together.
