The content of the invention

Problems to be solved by the invention

In recent years, for various articles, the particularly article of everyday use such as medicated clothing, case and bag and footwear such as clothing, theirs are installed on Slide fastener is also regarded as one of design element, expects to improve including the overall exterior quality of the article including slide fastener.And, in the past, Generally by slide fastener to be linearly installed on the article as slide fastener installation component, but in recent years, the convenience, design from article For etc. viewpoint, also there is the situation that slide fastener is installed on slide fastener installation component with the state for being for example bent into bending etc..

In this regard, the conventional slide fastener with the tooth chain belt 80 described in the patent documentation 1 is by fixing The zipper strip suture for having the chain tooth of sequential like is fixed on the opening/closing portion of slide fastener installation component (for example, clothing etc.) to be used 's.Therefore, in order to successfully slide fastener being stitched together with slide fastener installation component using sewing machine, therefore, to assure that the phase of zipper strip It is wider to a certain extent in the width dimensions with main part that the position on the outside of by bandwidth direction is exposed than in chain tooth, to make For tape edge.

However, in the case where slide fastener is installed on slide fastener installation component with the state for being for example bent into bending etc., having The peripheral part of Shi Zuowei slide fasteners with main part local significantly heave, be recessed, in the inner circumferential side for being bent into forniciform slide fastener Zipper strip produce undulatory larger pleat.

Accordingly, it is difficult to the sewing to slide fastener installation component be carried out using sewing machine, also, the article of slide fastener is being installed In, if when zipper strip is heaved, is recessed or produces undulatory pleat, there is also makes the aesthetic property (exterior quality) of article Problem as reducing.

Also, in order to solve such problem, for example, consider not use zipper strip but the chain tooth of sequential like is directly stitched Close on the cloth such as clothes for example as slide fastener installation component.In this case, the chain tooth of sequential like is sewn on cloth Operation be by for example carrying out in the manufacturer for manufacturing the product (clothes) etc., but sequential like to be carried out by manufacturer such During the suture of chain tooth, it is difficult to suitably carry out chain tooth relative to the para-position of cloth, by the interval (installing space) between each chain tooth Constant size is remained stably.

Also, in the case of on the side edge part (installation edge) for be directly sewn to chain tooth cloth, for example, in the cloth Side edge part end face expose in the state of when sewing on chain tooth, there is a problem in that：Enter in the opening and closing operations of slide fastener repeatedly Side edge part in capable process in cloth bursts at the seams, and the engagement of chain tooth, the sliding of pull head to left and right brings bad shadow Ring.

The effect of invention

The tooth chain belt that the present invention is provided has the chain tooth supporting member of multiple chain tooths and banding of sequential like, the chain tooth bag Engageable head, upper leg, lower leg and linking part are included, the chain tooth supporting member is with the doubling between upper leg and lower leg State is configured along zipper length direction.

Also, chain tooth supporting member has：Kink, which is between the upper leg of chain tooth and lower leg towards engageable head Lateral bending is converted into substantially U-shaped；Upper lower limb supporting slice portion, which is from one end of kink along upper leg extension and upper leg can suture In upper lower limb supporting slice portion；And lower lower limb supporting slice portion, which is from the other end of kink along lower leg extension and lower leg Can be sewn in lower lower limb supporting slice portion.In which case it is preferable that, chain tooth supporting member is with difficult on zipper length direction The construction of the difficult retractility to stretch.

In the case of the tooth chain belt of such present invention, the upper leg of chain tooth and lower leg-portions sewn are in chain tooth supporting member On, it is constant big therefore, it is possible to stably be remained the interval (installing space) between each chain tooth using chain tooth fixing component It is little.

In addition, the chain tooth supporting member of the present invention need not guarantee to exist compared to chain tooth as conventional so-called zipper strip The part that position in the outer part is exposed is wider using as tape edge, therefore, it is possible to realize lightweight, the cost cutting of slide fastener.In addition, In the present invention, chain tooth supporting member also can be with the part exposed in position in the outer part compared to chain tooth, it is also possible to (slide fastener installation component for example as described later, is protected not receive from the purpose different as the effect of tape edge of conventional zipper strip Purpose that the flange part of pull head affects etc.) using the portion exposed in position in the outer part compared to chain tooth of the chain tooth supporting member Point.

Additionally, in the case of the tooth chain belt of the present invention, it is not necessary to guarantee chain tooth supporting member compared to chain tooth outer The part that the position of side is exposed is wider, therefore for example tooth chain belt can be installed on to be bent into the in stable condition of bending etc. Slide fastener installation component.Even if also, tooth chain belt is installed on into slide fastener installation component with case of bending, it is not easy to support structure in chain tooth Part is produced to be heaved, is recessed or undulatory pleat etc., therefore, it is possible to improve the aesthetic property with slide fastener article (exterior quality).

Additionally, in the case of the tooth chain belt of the present invention, supporting with lower lower limb in the upper lower limb supporting slice portion of chain tooth supporting member Incorporating section is provided between piece portion, the installation edge (side edge part) of slide fastener installation component can clamp and be accommodated in the incorporating section.Thus, The tooth chain belt of the present invention is being clipped in the installation edge of slide fastener installation component between lower limb supporting slice portion and lower lower limb supporting slice portion Incorporating section in mode when being sewn on the installation edge, chain tooth supporting member can be utilized to limit the position of the installation edge Put, to avoid the installation edge too near by engageable head, thereby, it is possible to suitably carry out chain tooth relative to slide fastener installation component The para-position of edge is installed, tooth chain belt can be stably installed at the assigned position of slide fastener installation component.

Also, when the tooth chain belt of the present invention is installed on the installation edge of slide fastener installation component, slide fastener installation component The side end face for installing edge is surrounded and protected by the kink of chain tooth supporting member.Thus, afterwards in the chain tooth of tooth chain belt Row are installed pull head and when forming slide fastener, even if making pull head slide, be repeated the opening and closing operations of slide fastener, are not easy to by bending The side end face of the installation edge of portion's protection is burst at the seams, therefore, it is possible to solve the conventional various problems caused by bursting at the seams.

Additionally, the tooth chain belt of the present invention is formed as, can by chain tooth centered on engageable head elastic deformation and make this The thickness of the installation edge of the thickness for receiving the incorporating section of slide fastener installation component and slide fastener installation component of tooth chain belt Correspondingly increase/reduction.Thus, the interval between the upper leg of chain tooth and lower leg and the installation edge of slide fastener installation component Thickness correspondingly changes, but the thickness of the installation edge regardless of slide fastener installation component, can be by the engagement post of the chain tooth Size (height dimension) on the above-below direction in portion is stably maintained the size in prescribed limit.

So, the no matter thinner thickness of the installation edge of slide fastener installation component or thicker, due to the engageable head of chain tooth It is highly stable, thus for example by a kind of aftermentioned such pull head with convex platform portion and lower convex platform portion can slide When mode is installed on the chain denture of the tooth chain belt of the present invention, can be between the convex platform portion of pull head and lower convex platform portion stably Guiding engageable head, further, it is possible to make pull head be not susceptible to rock when sliding using the guiding.

And, pull head guides the engageable head of chain tooth when sliding, therefore the upper leg of chain tooth and lower leg can be unlike Upper flange and lower wing plate sliding contact of the conventional common slide fastener like that with pull head, thus for example no matter the upper leg of chain tooth and Height dimension between lower leg how, can set the interval between the upper flange and lower wing plate of pull head to a certain extent It is largerly fixed.

Thus, when tooth chain belt is installed on the installation edge of slide fastener installation component, even if due to the peace of slide fastener installation component Dress edge is thicker and height dimension of between the upper leg of chain tooth and lower leg is larger, it is also possible to prevent the chain tooth when pull head slides Upper leg and lower leg crimp with the upper flange and lower wing plate of pull head, it is brisk and successfully therefore, it is possible to stably guarantee pull head Slide.Also, sewing line (sewing line) that chain tooth is sewn in chain tooth supporting member, tooth chain belt is sewn to slide fastener peace The sewing line (secondary sewing line) installed on edge of dress component is not easy to and pull head friction, therefore can also solve these sewing lines Such problem is cut off because of the friction between pull head.

In the case of the tooth chain belt of such present invention, upper lower limb supporting slice portion and lower lower limb supporting slice portion are in slide fastener width side It is configured in the forming region of upper leg and lower leg of chain tooth upwards, is formed as shorter than the upper leg and lower leg of chain tooth.By This, can realize lightweight, the cost cutting of slide fastener.In addition, tooth chain belt is being installed on the state for being bent into bending etc. During slide fastener installation component, undulatory pleat etc. will not be produced in chain tooth supporting member, can stably carry out the installation of tooth chain belt.

In addition, in the present embodiment 1, after a pair of tooth chain belts 1 are sewn on cloth 8, pull head 40 is installed on this The chain denture 11 of tooth chain belt 1 and the 1st block piece and the 2nd block piece are installed on into cloth 8.But, in the present invention, it is also possible to For example after the chain denture 11 that pull head 40 is installed on a pair of tooth chain belts 1, by the flush joint of secondary sewing line 52 by the tooth chain Band 1 is sewn on cloth 8.

In the case where including according to the clothes of the slide fastener 5 of the present embodiment obtained in upper type 1, using U will be bent into The chain tooth supporting member 20 of shape is configured in the tooth chain belt 1 of the present embodiment 1 between leg 13 and lower leg 14 and is formed and drawn Chain 5, therefore, it is possible to easily realize lightweight, the cost cutting of slide fastener 5.

In addition, for the tooth chain belt 1 of the present embodiment 1, though for example by tooth chain belt 1 in the way of being bent into bending etc. In the case of being installed on clothes, as chain tooth supporting member 20 is without exposing in position in the outer part compared to chain tooth 10 Will not produce the zipper strip existing for conventional slide fastener 5 heave, be recessed or ripple shape pleat the problems such as such that it is able to improve The exterior quality of product.

In addition, in the case of the slide fastener 5 of the present embodiment 1, the side end face of the installation edge 8a of cloth 8 supports structure by chain tooth Part 20 is wrapped up, even if for example do not enter to exercise to cloth 8 to install edge 8a turning back the end portion treatment for waiting, it is also possible to using chain tooth supporting Edge 8a is installed in the protection of component 20.

Thus, the opening and closing operations of slide fastener 5 are repeated even if making pull head 40 slide, are not easy in the side for installing edge 8a End face bursts at the seams, even if also, burst at the seams in the side end face for installing edge 8a, it is also possible to it is effectively prevented the cunning of pull head 40 Dynamic property is reduced.

Additionally, in the case of the slide fastener 5 of the present embodiment 1, the installation edge 8a of cloth 8 is accommodated in upper leg 13 with Be bent between leg 14 in the chain tooth supporting member 20 of U-shaped, therefore, cloth 8 installation edge 8a such as the present embodiment 1 that Sample formed it is thicker in the case of, the interval (height dimension) between upper leg 13 and lower leg 14 is because of the installation edge of cloth 8 8a and somewhat expand, but thickness of the height dimension of engageable head 12 regardless of installation edge 8a, be stably maintained for Size in prescribed limit.

Thus, when slide fastener 5 is formed, as pull head 40, the thickness of the installation edge 8a regardless of cloth 8, can make With the interval between convex platform portion 48 as shown in Figure 7 and lower convex platform portion 49 and the height dimension of the engageable head 12 of chain tooth 10 Adaptable a kind of unitized pull head 40.Thus, it is not necessary to for example correspondingly prepare with the thickness of the installation edge 8a of cloth 8 The different various pull heads in interval between upper flange and lower wing plate, therefore, it is possible to improve economy, are capable of the thing of subduction zone slide fastener 5 The manufacturing cost of product.

Also, in this case, when the chain tooth 10 of left and right is in the chain tooth path of navigation of pull head 40, as shown in fig. 7, The convex platform portion 48 of pull head 40 and lower convex platform portion 49 limit the action on the above-below direction of engageable head 12, and pull head 40 is upper Flange part 46 and lower flange portion 47 be relative with the lateral border of the upper leg 13 and lower leg 14 of left and right and the left and right of restriction chain tooth 10 Action on direction such that it is able to make chain tooth 10 stable relative to 40 position of pull head.

Thus, it is possible to the chain tooth path of navigation along the substantially Y shape of pull head 40 guides smoothly and stably chain tooth 10, by This, the chain tooth 10 that can be effectively prevented left and right is rocked in the chain tooth path of navigation of pull head 40, so as to stably carry out left and right The engagement action of chain tooth 10, separating action.

And, convex platform portion 48 and lower convex platform portion 49 of the engageable head 12 of chain tooth 10 by pull head 40 when pull head 40 slides Guiding, sets larger therefore, it is possible to the interval between upper flange 43 and lower wing plate 44 to a certain extent by pull head 40.

Thus, even if as the installation edge 8a of cloth 8 is thicker between the upper leg 13 of chain tooth 10 and lower leg 14 Height dimension is larger as in this embodiment 1, it is also possible to prevent the upper leg 13 of chain tooth 10, lower leg 14 when pull head 40 slides Upper flange 43, lower wing plate 44 with pull head 40 is crimped, and can stably be guaranteed the brisk of pull head 40 and smoothly be slided.Also, The sewing line 51 that chain tooth 10 is sewn in chain tooth supporting member 20, secondary sewing tooth chain belt 1 being sewn on cloth 8 Line 52 be not easy to and pull head 40 occur friction, therefore be not susceptible to a sewing line 51, secondary sewing line 52 because with pull head 40 Between friction and be cut off such problem.

In addition, in the embodiment 1, the situation that thicker cloth 8 is installed on to tooth chain belt 1 is illustrated, but right In the tooth chain belt 1 of the present embodiment 1, as long as the thickness of cloth is the upper lower limb supporting slice portion 22 of the chain tooth supporting member 20 of tooth chain belt 1 Lateral border and the lateral border in lower lower limb supporting slice portion 23 between height dimension size below, it becomes possible to the tooth chain belt 1 is pacified Loaded on the cloth.Thus, it is also possible to as in such as Fig. 8 and Fig. 9 to the cloth as shown in 1 variation of embodiment in thinner thickness Material 9 is installed tooth chain belt 1 to form slide fastener 5a.

That is, the tooth chain belt 1 of the variation is same with the tooth chain belt 1 of the embodiment 1, will be the tooth chain belt 1 same with embodiment 1 The installation edge 9a of the cloth 9 of thinner thickness for the cloth 8 for using in embodiment 1 is installed on sample, compares, so as to be formed The slide fastener 5a of variation, and produce the article with slide fastener 5a.In this case, pull head 40 is using same as Example 1 Unitized pull head 40.

In the case of the slide fastener 5a of the variation for being formed like this, tooth chain belt 1 is sewed with the cloth 9 of thinner thickness, The upper leg 13 and lower leg 14 of the chain tooth 10 being therefore sewn on cloth 9 is sutured securely using secondary sewing line 52.Thus, The upper surface of upper leg 13 is less for the situation of embodiment 1 compared with the height dimension between the lower surface of lower leg 14, but The height dimension A of the engageable head 12 of the chain tooth 10 is maintained the size roughly the same with the situation of embodiment 1.

Thus, when the chain tooth 10 of left and right is in the chain tooth path of navigation of pull head 40, as shown in figure 9, pull head 40 is upper Boss portion 48 and lower convex platform portion 49 limit the action on the above-below direction of engageable head 12, and 46 He of upper flange part of pull head 40 Lower flange portion 47 with left and right upper leg 13 and lower leg 14 lateral border it is relative and limit chain tooth 10 left and right directions on moving Make such that it is able to make chain tooth 10 stable relative to 40 position of pull head.

Chain tooth path of navigation therefore, it is possible to the substantially Y shape along pull head 40 guides smoothly and stably chain tooth 10, by This, the chain tooth 10 that can be effectively prevented left and right is rocked in the chain tooth path of navigation of pull head 40, so as to stably carry out left and right The engagement action of chain tooth 10, separating action.

Also, in the case of the slide fastener 5a of the variation, in the same manner as the situation of embodiment 1, it is prevented from pull head The upper leg 13 of chain tooth 10 during 40 slip, the upper flange 43 of lower leg 14 and pull head 40, lower wing plate 44 are crimped, can be stably Guarantee the brisk of pull head 40 and smoothly slide.Also, sewing line 51, a secondary sewing line 52 are not easy to be occurred with pull head 40 Friction, therefore be not susceptible to as sewing line 51, secondary sewing line 52 be cut off because of the friction between pull head 40 Problem.
