The effect of invention
In slide fastener of the present invention, the plastic slide fastener coupling element be fixed on zipper strip has the chain tooth first half and chain tooth Lower Half, the described chain tooth first half has: the first band holding part, from this first band holding part to the first head of the extended thin narrow shape in front end in band outside, described chain tooth Lower Half has: the second band holding part, have by the neck of the shape having received thin, the second head of shape of expanding.And be formed with convergent portion at the described chain tooth first half, this convergent portion at least makes the side, front on the strip length direction in the first band holding part and the size between side, rear reduce gradually upward.
There is the slide fastener of the present invention of so plastic slide fastener coupling element, compared with there is the slide fastener of metal slide fastener coupling element, can weight be reduced.In addition, slide fastener coupling element of the present invention is owing to being formed with convergent portion at the chain tooth first half, so the area that is fixed on zipper strip can be expanded thus improve the constant intensity of this slide fastener coupling element, and the size (that is, chain tooth width dimensions) that can reduce on the strip length direction of the upper surface of the chain tooth first half.Therefore, this slide fastener coupling element can have the good exterior quality to the sensation of people's fashion and magnificent impression as metal slide fastener coupling element.
In such slide fastener of the present invention, the chain tooth first half has avoiding interference portion, when under the state engaged at the slide fastener coupling element of left and right by zipper strip to when making the approximating direction warpage of the chain tooth first half, this avoiding interference portion can avoid the interference of the chain tooth first half of the first head and engagement the other side side.
Such as, when have slide fastener coupling element first band holding part on the slide fastener of the plastic slide fastener coupling element in the past in the such convergent portion of the present invention is not set, the chain tooth first half of each slide fastener coupling element is widely formed on strip length direction (chain tooth width), and the interval of the chain tooth upper surface side between adjacent slide fastener coupling element is set less.
Therefore, for this slide fastener, when under the state that the chain tooth Lower Half of the state that the slide fastener coupling element in left and right has engaged, slide fastener coupling element namely in left and right has been engaged with each other by zipper strip to when making the approximating direction warpage of the chain tooth first half, after zipper strip is flexed into the radius of curvature of certain degree, between adjacent slide fastener coupling element, front side edge and the rear side edge of the upper surface side of the first band holding part abut.
Therefore, this zipper strip is limited to flex into the radius of curvature less than this degree, and its result is, in second side of zipper strip, interval between second head of adjacent chain tooth Lower Half can not be expanded to larger than the size of regulation, so, can prevent the engagement of the slide fastener coupling element of left and right from throwing off.
But, as the present invention, when being formed with the slide fastener in convergent portion in the first band holding part of slide fastener coupling element, although be fixed on the spacing of the slide fastener coupling element on zipper strip and do not change in the past, the size on the strip length direction of the upper surface part of the first band holding part of each slide fastener coupling element reduces.Therefore, the interval of the chain tooth upper surface side between adjacent slide fastener coupling element must become large compared with slide fastener in the past.
Therefore, for slide fastener of the present invention, when under the state that the chain tooth Lower Half of the slide fastener coupling element in left and right has been engaged with each other by zipper strip to when making the approximating direction warpage of the chain tooth first half, this zipper strip easily can be flexed into less radius of curvature compared with slide fastener in the past.Now, between adjacent slide fastener coupling element, before the first band holding part is against each other, the first head of the chain tooth first half and the chain tooth first half interference of engagement the other side side.
Like this, when zipper strip in slide fastener of the present invention flexes into radius of curvature little than ever, if the chain tooth first half of the first head of the chain tooth first half and engagement the other side side is interfered, then the part of this interference becomes fulcrum, and the chain tooth Lower Half of the mutually adjacent slide fastener coupling element of engagement the other side side is rotated to the direction be separated, so the interval between the second head of this slide fastener coupling element expands simply than the size of regulation.Its result is, enough cannot maintain the engagement of chain tooth Lower Half of left and right, causes the engagement of the slide fastener coupling element of left and right to be thrown off, so be likely called as the unfavorable condition that so-called chain splits.
Therefore, in the present invention, in order to improve the unfavorable condition that the chain that causes splits because forming convergent portion in the first band holding part of slide fastener coupling element, the chain tooth first half arranges avoiding interference portion as described above.
Thus, when under the state engaged at the slide fastener coupling element of left and right by zipper strip warpage time, even if this zipper strip is flexed into radius of curvature little than ever, also the interference of the chain tooth first half of the first head and engagement the other side side can reliably be avoided, so, can prevent with this interference portion for fulcrum, slide fastener coupling element rotates to the direction be separated.Its result is, the interval between the second head of slide fastener coupling element can not be expanded to larger than the size of regulation, so, can prevent the engagement of the slide fastener coupling element of left and right from throwing off, thus can stably maintain its engagement.
In this situation, described avoiding interference portion is by having thinner wall section from the thin-walled start portion being set in the chain tooth first half to the first head side and being formed, and this thinner wall section makes the height dimension of the above-below direction of slide fastener coupling element less than the height dimension of thin-walled start portion.Thus, when under the engagement at slide fastener coupling element by zipper strip to when making the approximating direction warpage of the chain tooth first half, reliably can avoid the interference of the chain tooth first half of the first head and engagement the other side side.
Now, the inclined-plane that dips down that the described thinner wall section mode that has the height dimension of slide fastener coupling element is reduced gradually to the front end of the first head from thin-walled start portion is downward-sloping.Thus, the exterior quality of slide fastener coupling element can not be reduced, easily avoiding interference portion as described above can be arranged on the chain tooth first half.
Especially, in this case, dipping down inclined-plane relative to being positioned at compared with the thin-walled start portion of the chain tooth first half is with the angle of inclination of upper surface of inner side to be set to more than 15 ° and less than 90 °, preferably more than 20 ° less than 45 °.By making this angle of inclination be more than 15 °, being especially more than 20 °, reliably can being avoided the interference of the chain tooth first half of the first head and engagement the other side side by described avoiding interference portion.In addition, by making angle of inclination less than 90 °, being especially less than 45 °, also can not causing the reduction of the exterior quality of slide fastener coupling element.
In addition, in slide fastener coupling element of the present invention, the height dimension of the slide fastener coupling element at the front end place of the first head is set to 50% of the height dimension of the slide fastener coupling element than the position being configured with thin-walled start portion greatly, and below 80%.
By making the height dimension at the front end place of the first head larger than 50% of the height dimension at thin-walled start portion place, be preferably set to more than 60%, the first head reliably can be formed into the front end of chain tooth Lower Half, therefore can not reduce the exterior quality of slide fastener coupling element.In addition, be set as less than 80% of the height dimension at thin-walled start portion place by the height dimension at the front end place by the first head, preferably less than 75%, the interference of the chain tooth first half of the first head and engagement the other side side can be avoided by avoiding interference portion more reliably.
And in slide fastener coupling element of the present invention, the size the bandwidth direction from the front end of the first head to thin-walled start portion is set as more than 45% of the length dimension at whole described slide fastener coupling element.Thereby, it is possible to avoided the interference of the chain tooth first half of the first head and engagement the other side side more reliably by avoiding interference portion.
In addition, in slide fastener of the present invention, the described convergent portion of each slide fastener coupling element is set to more than 5 ° relative to the cone angle of chain tooth above-below direction, is preferably more than 10 °.And the maximum of size on the strip length direction (chain tooth width dimensions) of the upper surface of the first band holding part of each slide fastener coupling element is set to maximum 70% little than the size on the strip length direction of this first band holding part.
By like this cone angle in convergent portion being set as more than 5 °, and the maximum of size on the strip length direction of the upper surface of the first band holding part is set as 70% of maximum than the size on the strip length direction of this first band holding part is little, the size on the strip length direction of the upper surface side of the first band holding part can be reduced, thus the outward appearance that each slide fastener coupling element be fixed on zipper strip can be made to be formed as metal slide fastener coupling element.
In addition, cone angle of the present invention, when the convergent face such as forming convergent portion is formed by tabular surface, refer to the angle of inclination of convergent face relative to chain tooth above-below direction, in addition, when convergent face is formed by flexure plane, refer to the angle of inclination of the tangent line of the lower end of flexure plane relative to chain tooth above-below direction.
In addition, in slide fastener of the present invention, the interior angle of the leading section of the first head is set to less than 30 °, preferably less than 20 °.Thereby, it is possible to make the outward appearance of each slide fastener coupling element seem more as metal slide fastener coupling element.
And, the maximum of the size on the strip length direction of the second head of each slide fastener coupling element be set to the maximum of the size on the strip length direction of the second band holding part more than 85% and below 95%.
By the maximum of the size on the strip length direction of the second head being set as more than 85% of the maximum of the size in the second band holding part, when the slide fastener coupling element engagement making left and right, stably can obtain enough joggled strengths of the use can bearing slide fastener, and, even if warpage zipper strip under the state that the slide fastener coupling element of left and right has engaged, the generation that also can reliably prevent chain from splitting.
In addition, by the maximum of the size on the strip length direction of the second head being set as less than 95% of the maximum of the size in the second band holding part, when sliding such as making pull head thus make the slide fastener coupling element engagement of left and right, this engagement action can be carried out swimmingly.

In addition, in a part for first band holding part 12 side of the first band holding part 12 in this chain tooth first half 11 and the first head 13, upper surface from the lower ora terminalis of the chain tooth first half 11 to this chain tooth first half 11 is provided with convergent portion 14, and this convergent portion 14 makes the size between the side, front of this chain tooth first half 11 and side, rear reduce gradually upward.In this situation, be configured with the flexure plane that the side, front of the chain tooth first half 11 in convergent portion 14 and rear side face are formed as small curve as shown in Figure 5.In addition, in the present invention, also this side, front and side, rear can be formed as smooth plane.
In the present embodiment 1, the taper angle theta 2 in the convergent portion 14 relative to the inclination of chain tooth above-below direction is as shown in Figure 5 set to 10 °.Because convergent portion 14 has such taper angle theta 2, so, (namely first be with the size of the upper surface of holding part 12 on strip length direction, chain tooth width dimensions) such as can be configured to: as shown in figures 2 and 5 like that the maximum W2 of the size of upper surface on strip length direction of this first band holding part 12 than maximum W1 (that is, first being with the chain tooth width dimensions of the lower end of holding part 12) 70% little of the size of the first band holding part 12 on strip length direction.In addition, when the present embodiment 1, described maximum W2 be configured to be described maximum W1 about 62% size.Thus, when observing the slide fastener 1 of the present embodiment 1 from front, the form of the plastic each slide fastener coupling element 10 be fixed on zipper strip 2 can be made to look as metal slide fastener coupling element.
In addition, the extended front end to chain tooth Lower Half 21 of described first head 13 in this chain tooth first half 11, and be formed as size on its strip length direction shape carefully narrow from the front end reduced gradually towards front end with the first base end part being with holding part 12 to engage of this first head 13.Due to the extended front end to chain tooth Lower Half 21 of this first head 13, so the outward appearance of slide fastener coupling element 10 can be made close to metal slide fastener coupling element.In addition, under the state that the slide fastener coupling element 10 of left and right engages, even if this slide fastener coupling element 10 is subject to the power (ejection force) in band table back of the body direction, also can prevents the engagement of this slide fastener coupling element 10 from throwing off easily, its engagement can be maintained.
And this first head 13 has the first narrow width part 13a being configured in the first band holding part 12 side; Be configured in the second narrow width part 13b of chain tooth front via bend 13c from this first narrow width part 13a, such as when being linked the lateral margin of the lateral margin at base end part place of the first head 13 and the front end of this first head 13 by straight line, described first narrow width part 13a is formed in the mode bloated laterally than this straight line, and described second narrow width part 13b is formed in the mode caved in the inside than this straight line.
Like this, by arranging the first narrow width part 13a and the second narrow width part 13b at the first head 13, the outward appearance of each slide fastener coupling element 10 can be made closer to metal slide fastener coupling element.And, in this first head 13, compared with the head (head shown in dotted lines in Figure 2) formed with the mode such as reduced gradually by same ratio from its base end part to leading section with chain tooth width dimensions, the chain tooth width dimensions of the second narrow width part 13b from the front end of the first head 13 to bend 13c is little, so, as described later, by the slide fastener 1 of the present embodiment 1 to (with reference to Fig. 8) when making the adjacent chain tooth first half 11 approximating direction warpage, this first head 13 and the chain tooth first half 11 interference of engaging the other side side can be prevented more reliably.
And, in this first head 13, compared with the head formed with the mode such as reduced gradually by same ratio from its base end part towards leading section with chain tooth width dimensions, the chain tooth width dimensions of the first narrow width part 13a from bend 13c to the base end part of the first head 13 is large, so, such as when the slide fastener coupling element 10 of left and right engages, even if this slide fastener coupling element 10 is subject to ejection force upward from below, also can be supported second head 24 of engagement the other side more reliably by the first narrow width part 13a, thus the engagement that can maintain slide fastener coupling element 10 is stablized.
In addition, in the present embodiment 1, as shown in Figure 2, the interior angle θ 3 of the leading section (the second narrow width part 13b) of the first head 13 is set to 20 °, and the front end of this first head 13 is formed as being implemented the such curved of chamfering.Thereby, it is possible to make the outward appearance of slide fastener coupling element 10 close to metal slide fastener coupling element, and improve the aesthetic feeling of slide fastener coupling element 10.
In addition, in the present invention, the interior angle θ 3 of the leading section of the first head 13 refers to, such as the present embodiment 1 is such, under the leading section of the first head 13 is formed as curved situation, in the front of the first head 13, along side, front and side, the rear description extended line at the position that chain tooth width dimensions reduces with constant ratio, the angle of the inner side of these extended lines intersection part.
In addition, the thin-walled start portion 15 of the height dimension minimizing starting the above-below direction making slide fastener coupling element 10 towards the front end of the first head 13 is provided with at the chain tooth first half 11 of the present embodiment 1, be formed with the thinner wall section 16 as avoiding interference portion described later from the front of this thin-walled start portion 15 to the first head 13, the height dimension of the above-below direction of the slide fastener coupling element 10 of this thinner wall section 16 is less than the height dimension of the slide fastener coupling element 10 at this thin-walled start portion 15 place.
In the present embodiment 1, described thin-walled start portion 15 is set in such position, that is: make the size L2 bandwidth direction (chain dental length direction) from the front end of the first head 13 to thin-walled start portion 15 be the size of 45% of the length dimension L1 of this whole slide fastener coupling element 10.
In addition, according to the shape etc. of slide fastener coupling element 10, this thin-walled start portion 15 can be arranged on and make described length dimension L2 be the optional position of more than 45% of described length dimension L1, but in order to reliably play the effect as avoiding interference portion, this thin-walled start portion 15 is preferably arranged on such position, that is: when the slide fastener coupling element 10 of left and right engages, observe in bandwidth direction, the ora terminalis of holding part 12 side is with than the front end of the first head 13 of engagement the other side side closer to first in the slide fastener coupling element 10 of this engagement the other side side in this thin-walled start portion 15 (namely, the ora terminalis contrary with the first head 13 side of the first band holding part 12) side.
And the described thinner wall section 16 of the present embodiment 1 has the inclined-plane 17 that dips down, this inclined-plane 17 that dips down is downward-sloping in the mode making the height dimension of the above-below direction of slide fastener coupling element 10 and reduce gradually from the front end of thin-walled start portion 15 to the first head 13.In this situation, relative to the chain tooth first half 11 than thin-walled start portion 15 upper surface in the inner part, the tilt angle theta 1 that the inclined-plane 17 that dips down tilts is set to 20 °.
Thus, in the slide fastener coupling element 10 of the present embodiment 1, such as, as shown in Figure 4, the height dimension H2 of the slide fastener coupling element 10 at the front end place of the first head 13 can be set as less than 80% of the height dimension H1 of the slide fastener coupling element 10 of the position being configured with thin-walled start portion 15.In addition, because the first head 13 described above is with the extended front end to chain tooth Lower Half 21 of required wall thickness, so described height dimension H2 is set to larger than 50% of described maximum H1.In fact, when the present embodiment 1, described height dimension H2 is set to the size of about 75% of described maximum H1.
Chain tooth Lower Half 21 in the slide fastener coupling element 10 of the present embodiment 1 forms with the chain tooth first half 11.This chain tooth Lower Half 21 comprises: have the size of the regulation on strip length direction and be with first the second band holding part 22 clamping the band side edge part of zipper strip 2 between holding part 12; Extended to band outside from the second band holding part 22, and the neck 23 of thin shape is received in the front and back had on strip length direction; Extended from the leading section of neck 23, and the second head 24 expanded to the front and back on strip length direction.
In addition, in this chain tooth Lower Half 21, as shown in figures 2 and 5, the maximum W3 of the size of the second head 24 on strip length direction is configured to the size of 88% of the maximum W1 being the size of the second band holding part 22 on strip length direction.Thus, when making the slide fastener coupling element 10 of left and right engage, stably can obtain enough joggled strengths of the use can bearing slide fastener 1, and the engagement action when slide fastener coupling element 10 of left and right is engaged can be carried out swimmingly.
And, in the slide fastener coupling element 10 of the present embodiment 1, be provided with layer difference portion 18a as shown in Figure 4 in the boundary portion 18 of the chain tooth first half 11 and chain tooth Lower Half 21, the height dimension from the layer difference portion 18a of chain tooth Lower Half 21 to the position of zipper strip 2 side is set than large to the height dimension at the position of chain tooth front from layer poor portion 18a.
Owing to arranging such layer difference portion 18a and making the height dimension of the chain tooth Lower Half 21 from this layer of difference portion 18a to zipper strip 2 side larger, so, when making the slide fastener coupling element 10 of left and right engage as shown in Figure 6 making such as not shown pull head slide, gap 8 as shown in Figure 7 can be set between the second head 24 of the slide fastener coupling element 10 of the first head 13 of the chain tooth first half 11 and engagement the other side side.Therefore, when making the slide fastener coupling element 10 of left and right engage, even if the relative altitude position dislocation of the slide fastener coupling element 10 about such as in the chain tooth guideway of pull head, the engagement action of this slide fastener coupling element 10 also can be carried out swimmingly.
