Description
本發明是關於咬合頭部兩面分別形成有咬合凸部和咬合凹部的金屬製單面鍊齒及具備該金屬製單面鍊齒之左右雙開式拉鍊。The present invention relates to a metal single-sided fastener element in which a nip portion and an occlusion recess are formed on both sides of the occlusal head, and a left and right double-open zipper including the metal single-sided sprocket.
皮包等的開口部，為了能夠開閉而廣泛使用拉鍊。上述的拉鍊其中之一，已知有在拉鍊齒條配置2個以頭對頭或尾對尾成相向之拉頭的左右雙開式拉鍊。左右雙開式拉鍊，只要2個拉頭沿著鍊齒列往前後任一方向滑動就能夠執行拉鍊齒條的開閉。In the opening of a bag or the like, a zipper is widely used in order to be able to open and close. One of the above-mentioned zippers is known to have two left and right double-open zippers in which the sliders are arranged head-to-head or tail-to-tail in the zipper rack. The left and right double-opening zippers can perform the opening and closing of the zipper rack as long as the two sliders slide in either direction along the sprocket row.
安裝在左右雙開式拉鍊的鍊齒有使用金屬製單面鍊齒的案例。使用金屬製單面鍊齒能夠獲得橫拉強度強，並且，具有金屬光澤面於設計方面也較優越的左右雙開式拉鍊。接著，金屬製單面鍊齒的形狀是在咬合頭部一方的面形成有咬合凸部，另一方的面形成有咬合凹部。The fasteners mounted on the left and right double-open zippers have the case of using metal single-sided sprocket. The use of metal single-sided sprocket teeth enables a strong left-hand zipper with a strong horizontal pull strength and a metallic luster surface that is superior in design. Next, the metal single-sided sprocket has a shape in which a nip portion is formed on one surface of the nip head, and the other surface is formed with a nip concave portion.
不過，採用一般金屬製單面鍊齒的左右雙開式拉鍊，當滑動一方拉頭執行金屬製單面鍊齒彼此的咬合及從咬合狀態分開時，滑動阻力較少能夠順暢執行滑動。接著，例如：當滑動另一方拉頭使金屬製單面鍊齒彼此從咬合狀態分開時，即使滑動阻力比上述一方拉頭滑動時還多少高一些，還是能夠使已咬合的金屬製單面鍊齒彼此順暢分開。However, the left and right double-opening zippers using a single metal single-toothed sprocket can smoothly slide when the sliding one of the metal single-side sprocket teeth is engaged and separated from the occlusal state. Then, for example, when the other slider is slid to separate the metal single-sided fastener elements from the engaged state, even if the sliding resistance is higher than that of the one of the sliders, the single-sided metal chain can be engaged. The teeth are smoothly separated from each other.
但是，當以另一方的拉頭使金屬製單面鍊齒彼此咬合時，滑動阻力就會變大，以致無法順暢執行拉鍊的開閉。However, when the metal single-sided fastener elements are engaged with each other by the slider, the sliding resistance becomes large, so that the opening and closing of the zipper cannot be smoothly performed.
其原因是，當使金屬製單面鍊齒彼此咬合時，咬合凹部的外側緣會一邊衝接一邊逐漸咬合在所要咬合的對方鍊齒的咬合頭部。因此，就無法順暢執行拉頭的滑動。The reason for this is that when the metal single-sided sprocket teeth are engaged with each other, the outer edge of the nip concave portion is gradually nip on the occlusal head of the other sprocket to be engaged. Therefore, the sliding of the slider cannot be smoothly performed.
為了防止咬合凹部的外側緣和所要咬合之對方鍊齒的咬合頭部之間的衝接有金屬製單面鍊齒形狀的各種提案。該金屬製單面鍊齒的一例，本申請人已經提案有經由拉鍊用鍊齒成型裝置(參照專利文獻1)成型的金屬製單面鍊齒，或拉鍊用鍊齒(參照專利文獻2)等。Various proposals have been made to prevent the shape of the metal single-sided sprocket from being flushed between the outer edge of the nip portion and the nip head of the other sprocket to be engaged. In the case of the single-sided sprocket of the metal, the present applicant has proposed a metal single-face fastener element molded by a fastener element for a fastener (see Patent Document 1), or a fastener element for a slide fastener (see Patent Document 2). .
專利文獻2所記載的金屬製單面鍊齒是專利文獻1成型裝置所能夠成型的金屬製單面鍊齒經改良後的拉鍊用鍊齒。此外，專利文獻2的圖面中，也圖示著專利文獻1金屬製單面鍊齒特徵部的構成。於是，為了說明專利文獻1成型裝置所能夠成型的金屬製單面鍊齒的特徵部構成，利用專利文獻2所記載的金屬製單面鍊齒的剖面圖及透視圖進行說明。The metal single-sided fastener element described in Patent Document 2 is a fastener element for a fastener having a single-sided fastener element which can be molded by the molding apparatus of Patent Document 1. Further, in the drawing of Patent Document 2, the configuration of the metal single-sided sprocket characteristic portion of Patent Document 1 is also shown. Then, a description will be given of a cross-sectional view and a perspective view of a metal single-sided fastener element described in Patent Document 2, in order to explain the characteristic portion configuration of a metal single-sided fastener element that can be molded by the molding apparatus of Patent Document 1.
第5圖中，圖示著專利文獻2的金屬製單面鍊齒的咬合頭部剖面圖，第6圖是圖示著專利文獻2金屬製單面鍊齒的咬合頭部的要部透視圖。專利文獻1的金屬製單面鍊齒，其特徵為是在咬合凹部35側的咬合頭部33的前端壁形成有斜狀面37。In the fifth drawing, a cross-sectional view of the occlusal head of the metal single-sided sprocket of Patent Document 2 is shown, and FIG. 6 is a perspective view of the main part of the occlusal head of the metal single-sided sprocket of Patent Document 2. . The metal single-sided sprocket of Patent Document 1 is characterized in that a slanted surface 37 is formed on the front end wall of the nip head 33 on the side of the nip recess 35.
另，第5圖及第6圖是以本發明的先前例2進行說明。In addition, Fig. 5 and Fig. 6 are explained in the previous example 2 of the present invention.
首先，於第5圖中，針對2個咬合頭部33b、33c咬合時的狀況進行說明。第5圖是圖示著咬合頭部33b開始咬合已經咬合在其他金屬製單面鍊齒的咬合頭部33a，而咬合頭部33c對咬合頭部33b才要開始咬合的狀態。First, in the fifth drawing, the state when the two bite heads 33b and 33c are engaged will be described. Fig. 5 is a view showing a state in which the occlusal head 33b starts to bite the occlusal head 33a which has been engaged with the other metal single-sided sprocket, and the occlusal head 33c starts to engage with the occlusal head 33b.
當滑動未圖示的拉頭，使2個咬合頭部33b、33c彼此咬合時，為了防止逐漸咬合的咬合凸部34c和被咬合的咬合頭部33b的前端壁36b會一邊衝接一邊咬合，在咬合頭部33b的前端壁36b形成有斜狀面37b。同樣地，針對咬合頭部33a、33c，為了防止與執行咬合的對方咬合凸部衝接，也分別在咬合頭部33a、33c的前端壁36a、36c形成有斜狀面37a、37c。When the sliders (not shown) are slid and the two occlusal heads 33b and 33c are engaged with each other, the occlusion convex portion 34c and the distal end wall 36b of the occluded occlusion head 33b are prevented from being spliced while being engaged. A slanted surface 37b is formed in the front end wall 36b of the nip head 33b. Similarly, in the occluded head portions 33a and 33c, oblique surfaces 37a and 37c are formed on the distal end walls 36a and 36c of the occlusal head portions 33a and 33c, respectively, in order to prevent the engagement of the occlusal convex portions with the occlusion.
另，第5圖是圖示著形成在咬合頭部33b的咬合凸部34b，通過形成在咬合頭部33a的前端壁36a的斜狀面37a的區域，***在咬合凹部35a內的狀態。In addition, Fig. 5 is a view showing a state in which the engaging convex portion 34b formed in the engaging head portion 33b is inserted into the engaging concave portion 35a in a region formed by the inclined surface 37a of the distal end wall 36a of the engaging head portion 33a.
接著，如第6圖所示，事先在咬合頭部33的前端壁36形成斜狀面37，能夠減少咬合時拉頭的滑動阻力，能夠順暢執行拉頭的滑動。然後，若事先將專利文獻1裝置所成型的金屬製單面鍊齒使用在左右雙開式拉鍊，就能夠提昇使金屬製單面鍊齒彼此咬合時的拉頭滑動性。Next, as shown in Fig. 6, the inclined surface 37 is formed in the front end wall 36 of the nip head 33 in advance, so that the sliding resistance of the slider at the time of the nip can be reduced, and the sliding of the slider can be smoothly performed. Then, when the metal single-sided fastener element formed by the apparatus of the patent document 1 is used in the right and left double-opening zipper in advance, the sliding property of the slider when the metal single-sided fastener elements are engaged with each other can be improved.
但是，即使專利文獻1的裝置所構成的金屬製單面鍊齒使用在左右雙開式拉鍊，但咬合後當橫拉力施加在左右雙開式拉鍊時，橫拉力就會作用在第6圖所示的金屬製單面鍊齒的咬合凹部35的開口緣39。再加上，因斜狀面37c是形成在咬合頭部33的前端壁36，所以咬合凹部35的開口緣39的壁厚就會構成為較薄。However, even if the metal single-sided fastener element formed by the apparatus of the patent document 1 is used for the left and right double-opening zipper, when the horizontal pulling force is applied to the left and right double-opening zipper after the occlusion, the transverse pulling force acts on the sixth drawing. The opening edge 39 of the bite recess 35 of the metal single-sided sprocket. Further, since the inclined surface 37c is formed at the front end wall 36 of the nip head 33, the thickness of the opening edge 39 of the nip recess 35 is made thin.
因此，對於壁厚變薄的咬合凹部35的開口緣39，當作用橫拉力的力矩時，開口緣39的撓曲量就會變大。接著，當開口緣39撓曲大時，拉頭的滑動性就會變差導致有危險性產生。Therefore, when the moment of the transverse pulling force is applied to the opening edge 39 of the nip concave portion 35 whose wall thickness is reduced, the amount of deflection of the opening edge 39 becomes large. Then, when the opening edge 39 is greatly deflected, the sliding property of the slider is deteriorated to cause a risk.
於是，就提案有即使橫拉力的力矩作用在咬合凹部35的開口緣39還是能夠使開口緣39撓曲量變小的改良品是專利文獻2所記載的金屬製單面鍊齒。專利文獻2的金屬製單面鍊齒，如第6圖所示，在咬合頭部33的前端壁36內側面形成有肋條38。Then, it is proposed that the improved product which can reduce the amount of deflection of the opening edge 39 even if the moment of the transverse pulling force acts on the opening edge 39 of the nip recess 35 is a metal single-face fastener element described in Patent Document 2. In the metal single-face fastener element of Patent Document 2, as shown in Fig. 6, a rib 38 is formed on the inner surface of the front end wall 36 of the nip head 33.
利用形成在咬合頭部33的前端壁36內側面的肋條38，提高開口緣39的剛性。接著，開口緣39剛性的提高，可構成為開口緣39撓曲量較少。開口緣39撓曲量較少，就能夠大幅提昇拉頭的滑動性。The rigidity of the opening edge 39 is increased by the ribs 38 formed on the inner side surface of the front end wall 36 of the nip head 33. Next, the rigidity of the opening edge 39 is increased, and the opening edge 39 can be configured to have a small amount of deflection. When the opening edge 39 has a small amount of deflection, the sliding property of the slider can be greatly improved.

專利文獻2所記載的金屬製單面鍊齒是專利文獻1所記載的金屬製單面鍊齒改良品，能夠大幅提昇拉頭的滑動性。再加上，可在已提高剛性能夠抵抗橫拉力之力矩的構成事先構成有鍊齒。但是，為了成型為專利文獻2所記載的金屬製單面鍊齒，必須在咬合凹部38內形成有肋條38，除此之外，還必須在咬合頭部33的前端壁36事先形成有斜狀面37c。因此，就必須使用複雜的模具形狀進行成型作業，導致金屬製單面鍊齒的製造步驟複雜。The metal single-sided fastener element described in Patent Document 2 is a metal single-sided fastener element described in Patent Document 1, and can greatly improve the slidability of the slider. Further, it is possible to form a fastener element in advance in a configuration in which the rigidity of the rigidity can be increased against the lateral pulling force. However, in order to form the metal single-face fastener element described in Patent Document 2, it is necessary to form the rib 38 in the engagement recess 38, and in addition, the front end wall 36 of the occlusion head 33 must be formed in a slant shape in advance. Face 37c. Therefore, it is necessary to perform a molding operation using a complicated mold shape, resulting in a complicated manufacturing step of the metal single-sided fastener element.
於是，本發明提供一種能夠防止咬合時的衝接並且能夠提高剛性抵抗橫拉力的力矩，再加上，能夠以簡單構造構成的金屬製單面鍊齒，同時提供一種使用該金屬製單面鍊齒之左右雙開式拉鍊。Accordingly, the present invention provides a metal single-sided sprocket capable of preventing the splicing at the time of nip and capable of improving the rigidity against the lateral pulling force, and providing a single-sided chain using the metal. Double-open zipper around the teeth.
為了達成上述目的，本發明的金屬製單面鍊齒，具有形成在咬合頭部一面側的咬合凸部和形成在另一面側的咬合凹部之單面鍊齒，其最主要的特徵為，在上述咬合頭部的前端緣和上述咬合凹部的開口緣之間的前端壁的上面部的局部，形成：從上述咬合頭部的前端緣側朝上述咬合凹部內，向下傾斜且具有指定的寬度的上部傾斜面，構成為上述咬合頭部前端緣側的上述咬合凹部內圍面的局部和上述上部傾斜面連接著。In order to achieve the above object, the metal single-face fastener element of the present invention has a single-sided fastener element formed on one side of the bite head and a single-sided fastener element formed on the other side of the engagement surface. The most important feature is that a portion of the upper surface portion of the distal end wall between the distal end edge of the occlusion head and the opening edge of the occlusion recess is formed to be downwardly inclined from the distal end side of the occlusion head toward the occlusion recess and has a predetermined width The upper inclined surface is formed such that a portion of the inner peripheral surface of the engaging recessed portion on the distal end edge side of the engaging head portion is connected to the upper inclined surface.
再加上，本發明的金屬製單面鍊齒，其主要特徵為，上述咬合頭部前端緣和該前端緣側的上述上部傾斜面的端緣之間是配設成分開。Further, the metal single-face fastener element according to the present invention is characterized in that the front end edge of the engagement head portion and the end edge of the upper inclined surface on the front end edge side are disposed apart.
又加上，本發明的金屬製單面鍊齒，其主要特徵為，與上述上部傾斜面連接的上述咬合凹部內圍面是形成從上述咬合凹部的底面朝外方擴開的下部傾斜面，上述上部傾斜面是構成為傾斜角度比上述下部傾斜面還淺。Further, the metal single-face fastener element according to the present invention is characterized in that the inner peripheral surface of the engagement recessed portion that is connected to the upper inclined surface is a lower inclined surface that is expanded outward from the bottom surface of the engagement recessed portion. The upper inclined surface is configured such that the inclination angle is shallower than the lower inclined surface.
另外，本發明的金屬製單面鍊齒，其主要特徵為，上述上部傾斜面的傾斜角度是比0度還大且為7度以下。Further, the metal single-sided fastener element of the present invention is mainly characterized in that the inclination angle of the upper inclined surface is larger than 0 degrees and is 7 degrees or less.
再加上，本發明的金屬製單面鍊齒，其主要特徵為，上述上部傾斜面的傾斜角度是3度以上且為7度以下。Further, the metal single-sided sprocket of the present invention is mainly characterized in that the inclination angle of the upper inclined surface is 3 degrees or more and 7 degrees or less.
又加上，本發明的金屬製單面鍊齒，其主要特徵為，上述上部傾斜面左右方向的橫寬尺寸，構成為在上述咬合凹部底面左右方向的橫寬尺寸89%~92%的尺寸範圍。Further, the metal single-sided sprocket according to the present invention is characterized in that the lateral width of the upper inclined surface in the left-right direction is a size of 89% to 92% in the lateral width of the bottom surface of the occlusion concave portion. range.
本發明的左右雙開式拉鍊，另一最主要的特徵為，構成具備有在左右一對的拉鍊布帶的相對側緣部，以指定間隔排列設有上述的本發明金屬製單面鍊齒的拉鍊繫條。Another main feature of the left and right double-opening zipper of the present invention is that the metal side single-sided fastener of the present invention is arranged at a predetermined interval along the opposite side edge portions of the pair of left and right fastener tapes. Zipper straps.
本發明相關的金屬製單面鍊齒，形成有朝咬合凹部內向下傾斜的上部傾斜面。因此，咬合凹部內所要咬合的對方側咬合凸部是能夠通過形成在咬合凹部的上部傾斜面側，描繪出***在咬合凹部內的軌道。接著，對方側的咬合頭部是藉由通過所要咬合的咬合凹部的上部傾斜面側，就能夠在與接著逐漸咬合的咬合凸部之間，事先設有避免衝接的間隙。因此，對於所要咬合的對方側咬合凹部，咬合凸部是能夠順暢逐漸咬合。The metal single-face fastener element according to the present invention is formed with an upper inclined surface that is inclined downward toward the inside of the engagement recess. Therefore, the other side occluding convex portion to be engaged in the nip concave portion can draw the trajectory inserted into the nip concave portion by being formed on the upper inclined surface side of the nip concave portion. Then, the occlusal head on the other side is provided with a gap for avoiding squeezing between the occluded convex portion which is gradually engaged with the occluded surface of the occluded concave portion to be engaged. Therefore, the occlusal convex portion can be smoothly and gradually engaged with the occlusal concave portion of the other side to be engaged.
專利文獻1、2所記載的金屬製單面鍊齒，如第5圖所示，咬合頭部33b的咬合凸部34b是通過形成在咬合頭部33a的斜狀面37a側，一邊描繪出嵌入在咬合頭部33a的咬合凹部35a內的軌道一邊和咬合凹部35a咬合。此外同樣地，咬合頭部33c的咬合凸部34c是通過形成在咬合頭部33b的斜狀面37b側，一邊描繪出嵌入在咬合頭部33b的咬合凹部35b內的軌道一邊和咬合凹部35b咬合。As shown in Fig. 5, the single-sided sprocket of the metal described in Patent Documents 1 and 2 is formed by inserting the nip portion 34b of the nip portion 33b on the side of the inclined surface 37a of the nip head 33a. The side of the rail in the engaging recess 35a of the engaging head portion 33a engages with the engaging recess 35a. Further, similarly, the engaging convex portion 34c of the engaging head portion 33c is formed on the side of the inclined surface 37b of the engaging head portion 33b, and the side of the rail embedded in the engaging concave portion 35b of the engaging head portion 33b is drawn and engaged with the engaging concave portion 35b. .
如上述，專利文獻1、2所記載的金屬製單面鍊齒是藉由通過斜狀面側，以在接著要逐漸咬合的咬合凸部之間設有避免衝接的間隙。相對於此，本發明相關的金屬製單面鍊齒，其咬合凸部是藉由通過形成在咬合前端的咬合凹部的上部傾斜面側，就能夠一邊避免咬合凸部和咬合前端的咬合凹部衝接，一邊避免和接著要逐漸咬合的咬合頭部的咬合凸部衝接。As described above, in the metal single-face fastener elements described in Patent Documents 1 and 2, by the oblique surface side, a gap for avoiding the punching is provided between the engagement convex portions to be gradually engaged. On the other hand, in the metal single-sided sprocket according to the present invention, the occlusal convex portion can be punctured by the occluded concave portion of the occlusal convex portion and the occlusal end portion by passing through the upper inclined surface side of the nip portion formed at the nip end. Then, while avoiding the occlusion convex portion of the occlusal head which is to be gradually engaged.
此外，本發明的金屬製單面鍊齒使用在左右雙開式拉鍊時，咬合後當橫拉力施加在左右雙開式拉鍊時，對於咬合凹部的開口緣，會有來自所要咬合的對方側咬合凸部的推壓力造成的力矩作用。即，對於金屬製單面鍊齒的咬合頭部的前端緣側的咬合凹部內圍面和上部傾斜面的連接部，會有橫拉力造成的力矩作用。Further, in the case of the metal single-sided fastener element of the present invention, when the left and right double-opening zipper is used, when the lateral pulling force is applied to the left and right double-opening zipper after the occlusion, the occlusal convex portion from the opposite side of the occluded concave portion may be engaged. The effect of the moment caused by the pushing pressure. In other words, the joint portion between the inner peripheral surface of the nip portion and the upper inclined surface on the front end edge side of the nip head of the metal single-sided sprocket has a moment action due to the lateral pulling force.
但是，本發明中，咬合凹部的開口緣的壁厚是構成較厚，所以對於咬合凹部的開口緣，即使有橫拉力的力矩作用，但咬合凹部的開口緣的撓曲量還是極小。如此一來，咬合頭部的前端緣側就不會產生足以造成拉頭滑動性變差的變形，能夠保持拉頭良好滑動性。However, in the present invention, since the thickness of the opening edge of the engaging recess is thick, the amount of deflection of the opening edge of the engaging recess is extremely small even if the opening edge of the engaging recess has a lateral pulling force. As a result, the front end edge side of the bite head does not have a deformation sufficient to cause the sliding property of the slider to deteriorate, and the slider can maintain good sliding property.
另外，本發明中，上部傾斜面，因是形成在咬合頭部的前端緣和咬合凹部的開口緣之間，所以就能夠使逐漸要咬合的對方側咬合凸部和咬合頭部的衝接面積構成為較少，能夠大幅提昇拉頭的滑動性。Further, in the present invention, since the upper inclined surface is formed between the front end edge of the nip head and the opening edge of the nip concave portion, the nip area of the nip portion and the nip head which are gradually engaged can be made. The configuration is small, and the sliding property of the slider can be greatly improved.
再加上，本發明中，因是構成為咬合頭部的前端緣和該前端緣側的上部傾斜面的端緣之間配設成分開，所以就能夠事先使咬合凹部開口緣的壁厚構成為更厚。因此，對於咬合凹部的開口緣即使有橫拉力的力矩作用，但咬合凹部開口緣的撓曲量還是會變得更小。Further, in the present invention, since the front end edge of the nip head and the end edge of the upper slanting surface on the front end side are disposed apart, the thickness of the opening edge of the nip recess can be formed in advance. To be thicker. Therefore, the amount of deflection of the opening edge of the nip concave portion becomes smaller even if the opening edge of the nip recess has a lateral pulling force.
本發明是事先在咬合凹部的內圍面形成有下部傾斜面，因此就能夠使逐漸要咬合的對方側咬合凸部容易納入咬合凹部內，並且，能夠使逐漸要咬合的對方側咬合凸部容易從咬合凹部脫離。According to the present invention, since the lower inclined surface is formed on the inner peripheral surface of the engaging recessed portion, the opposing side engaging convex portion that is gradually engaged can be easily incorporated into the engaging concave portion, and the engaging side portion that is gradually engaged can be easily occluded. Detach from the occlusal recess.
此外，事先將上部傾斜面的傾斜角度構成比下部傾斜面的傾斜角度還淺，能夠使已咬合的咬合凸部和咬合凹部下部傾斜面的抵接面積構成為較寬廣，能夠使咬合時的咬合狀態在事先就構成為較強。Further, the inclination angle of the upper inclined surface is formed to be shallower than the inclination angle of the lower inclined surface, and the abutment area of the engaged convex portion and the lower inclined surface of the engagement concave portion can be made wider, and the engagement at the time of the engagement can be made. The state is formed stronger in advance.
如上述，由於能夠事先將咬合凹部開口緣的壁厚構成為較厚，因此就能夠事先使咬合凹部開口緣的剛性更高。此外，能夠事先使咬合的對方側咬合凸部和咬合凹部下部傾斜面的抵接面積形成較大。As described above, since the thickness of the opening edge of the engagement recess can be made thick in advance, the rigidity of the opening edge of the engagement recess can be made higher in advance. Further, the abutting area of the engaged side engagement convex portion and the lower concave surface of the engagement concave portion can be made large in advance.
即，能夠使形成咬合的咬合凸部和咬合前端的下部傾斜面所抵接的面側的咬合凸部的重心位置比下部傾斜面開口緣還位於咬合前端的咬合凹部的底面側。換句話說，咬合凸部能夠以比下部傾斜面開口緣還重心低的狀態和咬合前端的咬合凹部咬合。In other words, the position of the center of gravity of the engaging convex portion on the surface side where the engaging convex portion and the lower inclined surface of the engaging end are abutted can be positioned on the bottom surface side of the engaging concave portion at the distal end of the engagement portion than the lower inclined surface opening edge. In other words, the nip convex portion can be engaged with the nip portion of the nip end at a lower center of gravity than the lower slant surface opening edge.
因此，即使橫拉力對形成咬合的對方側咬合凸部以咬合凹部的開口緣為中心有旋轉力矩作用，還是能夠防止該形成咬合的對方側咬合凸部以咬合前端的咬合凹部的開口緣為中心轉動，能夠防止咬合狀態分開。Therefore, even if the lateral pulling force acts on the opening side of the engaging recessed portion to form the engagement, the opposing side engaging projection can be prevented from centering on the opening edge of the engaging recess of the leading end. Rotation can prevent the seizure state from separating.
本發明中，上部傾斜面的傾斜角度是以比0度還大且7度以下為佳。更好的形態是上部傾斜面的傾斜角度構成為3度以上且7度以下。以上述角度範圍事先構成上部傾斜面的傾斜角度時，能夠使已咬合的咬合凸部和咬合凹部下部傾斜面的抵接面積事先就構成可足以維持拉鍊咬合強度的面積。In the present invention, the inclination angle of the upper inclined surface is preferably larger than 0 degrees and preferably 7 degrees or less. A more preferable form is that the inclination angle of the upper inclined surface is set to be 3 degrees or more and 7 degrees or less. When the inclination angle of the upper inclined surface is formed in advance in the above-described angular range, the abutting area of the engaged convex portion and the lower inclined surface of the engaging recess can be formed in advance in an area sufficient to maintain the zipper engagement strength.
若上部傾斜面的傾斜角度是構成比7度還大的角度時，則已咬合的咬合凸部和咬合前端的咬合凹部下部傾斜面的抵接面積就會變狹窄，導致抵抗橫拉力時的咬合強度變弱。再加上，於該狀況時，形成咬合的咬合凸部中，與咬合前端的下部傾斜面抵接之面側的咬合凸部的重心位置，會位於咬合前端的咬合凹部的下部傾斜面的開口緣附近位置，或是位於比下部傾斜面開口緣還上方的位置。When the inclination angle of the upper inclined surface is an angle larger than 7 degrees, the abutting area of the engaged convex portion and the lower concave surface of the nip portion at the nip end is narrowed, resulting in the occlusion against the transverse pulling force. The intensity is weak. In this case, the position of the center of gravity of the engaging convex portion on the surface side that abuts the lower inclined surface of the nip end in the occlusal convex portion that forms the occlusion is located at the opening of the lower inclined surface of the nip portion of the nip end The position near the edge or the position above the opening edge of the lower inclined surface.
即，咬合凸部是對下部傾斜面的開口緣以重心高的狀態和咬合前端的咬合凹部咬合。In other words, the engagement convex portion engages with the engagement recess of the engagement distal end in a state in which the center of gravity of the opening edge of the lower inclined surface is high.
如此一來，當形成咬合的咬合凸部以重心高的狀態和咬合前端的咬合凹部咬合時，若有橫拉力作用時，則咬合狀態容易分開。In this way, when the occlusal convex portion forming the occlusion is engaged with the occlusal concave portion at the distal end of the occlusion when the center of gravity is high, the occlusal state is easily separated if there is a lateral pulling force.
本發明的金屬製單面鍊齒，其上部傾斜面左右方向的橫寬尺寸若是構成比咬合凹部底面左右方向橫寬尺寸的92%還長時，上述傾斜面的橫寬就會構成為較寬廣，以致使咬合頭部前端壁上部側的壁厚構成較小。如此一來，就會產生咬合凹部的強度不足，同時也會降低抵抗橫拉力時的強度。In the metal single-sided sprocket of the present invention, when the horizontal width of the upper inclined surface in the left-right direction is longer than 92% of the lateral width of the bottom surface of the nip concave portion, the width of the inclined surface is wider. Therefore, the wall thickness of the upper side of the front end wall of the nip head is made small. As a result, the strength of the occlusal recess is insufficient, and the strength against the lateral pulling force is also reduced.
另外，上部傾斜面左右方向的橫寬尺寸若是構成比咬合凹部底面左右方向橫寬尺寸的89%還短時，上述傾斜面的橫寬就會構成為較狹窄，以致咬合頭部的上部傾斜面的兩側端部側的部位和咬合凸部的衝接面積就會增大，導致拉頭的滑動性變差。Further, when the horizontal width dimension of the upper inclined surface in the left-right direction is shorter than 89% of the lateral width of the bottom surface of the occlusion concave portion, the lateral width of the inclined surface is formed to be narrow, so that the upper inclined surface of the occlusal head is formed. The portion on the side of the end portion on both sides and the punching area of the nip portion are increased, resulting in deterioration of the slidability of the slider.
於是，為了保持拉頭的滑動性良好，事先確保咬合頭部前端壁的強度，最好是將上部傾斜面左右方向的橫寬尺寸事先構成為在咬合凹部底面左右方向橫寬尺寸的89%～92%的尺寸範圍。Therefore, in order to keep the slidability of the slider good, it is preferable to ensure the strength of the front end wall of the nip head in advance, and the lateral width of the upper slanting surface in the left-right direction is configured to be 89% of the horizontal width in the left-right direction of the bottom surface of the nip concave portion. 92% size range.
使用本發明相關的金屬製單面鍊齒，能夠製造左右雙開式拉鍊。構成為上述構成時，能夠大幅提昇2個拉頭的滑動性，並且能夠構成不會因橫拉力而使咬合狀態拉開的左右雙開式拉鍊。The left and right double-opening zippers can be manufactured by using the metal single-face fastener elements according to the present invention. In the above-described configuration, it is possible to greatly improve the slidability of the two sliders, and it is possible to configure a left and right double-open type slide fastener that does not open due to the lateral pulling force.

第1圖所示實施形態相關的金屬製單面鍊齒1，其製造是經由被稱為Y字型條棒的金屬製線材切斷成指定厚度尺寸，對切斷後鍊齒的咬合頭部3從上下方向施以壓製加工就能夠連續製造。或者是對金屬板至少進行1次以上的壓製加工，對壓製加工後的金屬板以金屬製單面鍊齒1的外圍形狀進行沖切，藉此就能夠連續製造第1圖所示本實施形態相關的金屬製單面鍊齒1。The metal single-sided fastener element 1 according to the embodiment shown in Fig. 1 is manufactured by cutting a metal wire member called a Y-shaped bar into a predetermined thickness dimension, and nip head 3 for the cut fastener element. It can be continuously manufactured by pressing processing from the top and bottom. Alternatively, the metal sheet may be subjected to at least one press working, and the metal sheet after the press working is punched by the outer shape of the metal single-face fastener element 1, whereby the embodiment shown in Fig. 1 can be continuously manufactured. Related metal single-sided fastener elements 1.
經由上述的壓製加工，就可在咬合頭部3上下方向一方的面形成有咬合凸部4，在另一方的面形成有咬合凹部5及上部傾斜面8。如下述，咬合凹部5的內圍面10當中咬合頭部3前端緣側的面即下部傾斜面10a和上部傾斜面8是連接形成簡單的形狀。根據該構成，即使沒有事先準備複數的壓製加工模具，至少經由一次的壓製加工還是能夠形成咬合凹部5及上部傾斜面8。Through the above-described press working, the engagement convex portion 4 can be formed on one surface of the bite head 3 in the vertical direction, and the engagement concave portion 5 and the upper inclined surface 8 can be formed on the other surface. As described below, the lower inclined surface 10a and the upper inclined surface 8 which are the surfaces of the inner peripheral surface 10 of the engaging recessed portion 5 which are engaged with the front end edge of the head portion 3 are connected to each other to have a simple shape. According to this configuration, even if the plurality of press-molding molds are not prepared in advance, the nip concave portion 5 and the upper inclined surface 8 can be formed at least once by press working.
如第1圖、第2圖所示，金屬製單面鍊齒1的後方側，形成有左右一對腳部2，此外，金屬製單面鍊齒1前方側的咬合頭部3，在金屬製單面鍊齒1上下方向的一面側形成有咬合凸部4[參照第2(b)圖、第2(c)圖]，在另一面側形成有咬合凹部5。As shown in Fig. 1 and Fig. 2, a pair of left and right leg portions 2 are formed on the rear side of the metal single-face fastener element 1, and the nip head 3 on the front side of the metal single-face fastener element 1 is in the metal. The occluded convex portion 4 is formed on one surface side of the one-side sprocket 1 in the vertical direction (see FIGS. 2(b) and 2(c)), and the nip concave portion 5 is formed on the other surface side.
從金屬製單面鍊齒1的上述另一面側的咬合頭部3前方側的前端緣7側，朝咬合凹部5內形成有向下傾斜的上部傾斜面8。上部傾斜面8是能夠以上述的壓製加工形成，但也可不進行壓製加工而是利用切削加工或研磨加工形成在咬合頭部3的前端緣7側。不過，上部傾斜面8利用壓製加工形成時，因上部傾斜面8等成型時的塑性變形是可產生加工硬化，所以能夠事先提高上部傾斜面8等的剛性。An upper inclined surface 8 that is inclined downward is formed in the engagement recess 5 from the side of the front end edge 7 on the front side of the nip head 3 on the other surface side of the metal single-sided sprocket 1 . The upper inclined surface 8 can be formed by the above-described press working, but may be formed on the front end edge 7 side of the nip head 3 by cutting or polishing without performing press working. However, when the upper inclined surface 8 is formed by press working, the plastic deformation at the time of molding the upper inclined surface 8 or the like is work hardening, so that the rigidity of the upper inclined surface 8 or the like can be increased in advance.
咬合凹部5的內圍面10，如第2(a)圖～第2(c)圖所示，呈現缽狀的形狀，構成為從咬合凹部5的底面5b朝外方擴開的形狀。接著，咬合凹部5的內圍面10當中，咬合頭部3的前端緣7側的下部傾斜面10a是構成和上述傾斜面8連接在咬合凹部5的開口緣5a。The inner peripheral surface 10 of the nip recess 5 has a meandering shape as shown in FIGS. 2(a) to 2(c), and is configured to expand outward from the bottom surface 5b of the nip concave portion 5. Next, among the inner peripheral surfaces 10 of the engaging recessed portion 5, the lower inclined surface 10a on the distal end edge 7 side of the engaging head portion 3 is an opening edge 5a that is connected to the inclined surface 8 and that is connected to the engaging recessed portion 5.
如第2(b)圖所示，上部傾斜面8的傾斜角度α是可事先形成為比0度還大且為7度以下的角度。最好是上部傾斜面8的傾斜角度α事先形成為3度以上且7度以下則為更佳構成。此外，上部傾斜面8的傾斜角度α，因是事先構成為比下部傾斜面10a的傾斜角度β還淺，所以下部傾斜面10a的傾斜角度β就是以形成為20度以上且30度以下的角度為較佳的構成。As shown in Fig. 2(b), the inclination angle α of the upper inclined surface 8 can be formed to be an angle larger than 0 degrees and 7 degrees or less in advance. It is preferable that the inclination angle α of the upper inclined surface 8 is formed to be 3 degrees or more and 7 degrees or less in advance. Further, since the inclination angle α of the upper inclined surface 8 is configured to be shallower than the inclination angle β of the lower inclined surface 10a, the inclination angle β of the lower inclined surface 10a is formed at an angle of 20 degrees or more and 30 degrees or less. It is a preferred composition.
接著，事先將下部傾斜面10a的傾斜角度β構成為20度～30度的角度範圍，當橫拉力作用在第3圖所示形成咬合的左右雙開式拉鍊1時，下部傾斜面10a就能夠使橫拉力的一部份釋放至上方的同時，能夠由下部傾斜面10a承接釋放後殘留的橫拉力。Then, the inclination angle β of the lower inclined surface 10a is previously set to an angular range of 20 to 30 degrees, and when the transverse pulling force acts on the right and left double-opening slide fastener 1 formed to be engaged as shown in Fig. 3, the lower inclined surface 10a can be made While a part of the lateral pulling force is released to the upper side, the horizontal pulling force remaining after the release can be received by the lower inclined surface 10a.
另外，如第2(c)圖所示，可事先將上部傾斜面8的橫寬B尺寸形成為咬合凹部5的底面5b的橫寬A尺寸的89%～92%的尺寸。底面5b的橫寬A尺寸，若是形成比上部傾斜面8的橫寬B尺寸的92%還長尺寸時，則上部傾斜面8的橫寬B就會構成較寬廣。因此，咬合頭部3的前端壁6上部側的壁厚就會變少，以致產生咬合凹部5的強度不足，同時抵抗橫拉力時的強度也會降低。Further, as shown in Fig. 2(c), the lateral width B of the upper inclined surface 8 can be previously formed to have a size of 89% to 92% of the lateral width A of the bottom surface 5b of the nip concave portion 5. When the horizontal width A of the bottom surface 5b is longer than 92% of the lateral width B of the upper inclined surface 8, the lateral width B of the upper inclined surface 8 is wider. Therefore, the wall thickness on the upper side of the front end wall 6 of the nip head 3 is reduced, so that the strength of the nip concave portion 5 is insufficient, and the strength against the lateral pulling force is also lowered.
此外，底面5b的橫寬A尺寸，若是形成比上部傾斜面8的橫寬B尺寸的89%還短尺寸時，則上部傾斜面8的橫寬B就會構成較狹窄。因此，咬合頭部3的上部傾斜面8的兩側端部側的部位和咬合凸部4的衝接面積就會增大，導致拉頭的滑動性變差。Further, when the lateral width A of the bottom surface 5b is formed to be shorter than 89% of the lateral width B of the upper inclined surface 8, the lateral width B of the upper inclined surface 8 is relatively narrow. Therefore, the portion on the both end sides of the upper inclined surface 8 of the nip head 3 and the nip area of the nip convex portion 4 are increased, resulting in deterioration of the slidability of the slider.
事先形成為上述構成時，就能夠於橫拉力作用在第3圖所示的左右雙開式拉鍊1時事先使咬合凹部5所咬合的對方側咬合凸部4和咬合凹部5的抵接面積形成為較大。根據該構成，當有橫拉力作用時，就能夠防止對方側的咬合凸部4從與其咬合凹部5的咬合狀態脫離，同時能夠由對方側咬合凸部4和咬合凹部5的抵接面積事先承接橫拉力。When the above-described configuration is formed in advance, it is possible to form the contact area of the other side engagement convex portion 4 and the engagement concave portion 5 in which the engagement concave portion 5 is engaged beforehand when the lateral pulling force acts on the left and right double-opening slide fasteners 1 shown in FIG. Larger. According to this configuration, when the lateral pulling force acts, it is possible to prevent the engagement convex portion 4 on the other side from being disengaged from the engagement state with the engagement recess portion 5, and the abutment area of the engagement side convex portion 4 and the engagement concave portion 5 can be taken in advance. Horizontal pull.
接著，藉由將對方側咬合凸部4和咬合凹部5的抵接面積構成較寬廣，能夠使橫拉力相對的每單位面積的拉伸應力變小。此外，還能夠事先使咬合凹部5的開口緣5a的前端壁6的壁厚構成較厚，能夠事先提高咬合凹部5的開口緣5a的剛性。Then, by making the contact area of the other side engaging convex portion 4 and the engaging concave portion 5 wider, it is possible to reduce the tensile stress per unit area with respect to the transverse pulling force. Further, the thickness of the front end wall 6 of the opening edge 5a of the engagement recess 5 can be made thicker in advance, and the rigidity of the opening edge 5a of the engagement recess 5 can be increased in advance.
再加上，即使有橫拉力作用，以致對咬合凹部5所咬合的對方側咬合凸部4以咬合凹部5的開口緣5a為中心有旋轉力矩作用時，還是能夠使形成咬合的對方側咬合凸部4和咬合凹部5的下部傾斜面10a的抵接面積事先形成為較大。如此一來，就能夠防止所咬合的對方側咬合凸部4以咬合凹部5的開口緣5a為中心朝分開方向轉動，能夠防止咬合狀態分開。In addition, even if there is a lateral pulling force, the opposing side engaging convex portion 4 that is engaged with the engaging recessed portion 5 has a rotational moment acting around the opening edge 5a of the engaging recessed portion 5, and the engaging side of the engaging side can be made convex. The abutting area of the lower inclined surface 10a of the portion 4 and the nip recess 5 is previously formed to be large. In this way, it is possible to prevent the engaged side engaging projections 4 from being engaged in the separating direction around the opening edge 5a of the engaging recess 5, thereby preventing the seizing state from being separated.
形成在咬合頭部3的咬合凸部4是在有橫拉力作用時形成為抵接於所咬合的對方側咬合凹部5的下部傾斜面10a。此時，為了讓抵接於對方側下部傾斜面10a的咬合凸部4的傾斜面4a和對方側下部傾斜面10a的抵接面積增大，上述咬合凸部4的傾斜面4a的傾斜角度可事先形成為對金屬製單面鍊齒1上下方向的軸成和下部傾斜面10的傾斜角度大致軸對稱之傾斜角度。The nip portion 4 formed in the nip head 3 is a lower inclined surface 10a that is formed to abut against the engaged counterpart side nip concave portion 5 when a lateral pulling force acts. At this time, in order to increase the contact area of the inclined surface 4a of the engaging convex portion 4 and the opposing lower inclined surface 10a that abuts against the opposing side lower inclined surface 10a, the inclined angle of the inclined surface 4a of the engaging convex portion 4 can be The angle of inclination of the axis of the metal single-sided sprocket 1 in the vertical direction and the inclination angle of the lower inclined surface 10 are substantially axially symmetrical.
第2(b)圖所示上部傾斜面8的傾斜角度α，若是構成比上述7度還大的角度時，當有橫拉力作用時，抵接在下部傾斜面10a的對方側咬合凸部4的抵接面積就會變小。因此，在對方側的咬合頭部3，就容易有形成咬合的咬合頭部3上面和咬合凹部5的邊界即開口緣當中，以上部傾斜面8和下部傾斜面10a的開口緣5a為中心朝咬合狀態分開方向轉動的轉動力矩作用，容易產生以咬合凹部5的開口緣5a為中心的轉動，導致咬合狀態容易分開。When the inclination angle α of the upper inclined surface 8 shown in Fig. 2(b) is an angle larger than the above-described 7 degrees, when the transverse pulling force acts, the other side engaging convex portion 4 abuts on the lower inclined surface 10a. The abutment area will be smaller. Therefore, in the occlusal head 3 on the other side, it is easy to have a boundary between the upper surface of the occluding head 3 that forms the occlusion and the occlusion recess 5, that is, the opening edge 5a of the upper inclined surface 8 and the lower inclined surface 10a. The rotational moment of the occlusal state in the direction of the separation is likely to cause the rotation centering on the opening edge 5a of the nip concave portion 5, so that the occlusal state is easily separated.
如第1圖及第2(a)圖、第2(b)圖所示，咬合頭部3的前端緣7和上部傾斜面8的前端緣7側的端緣8a之間是形成分開的構成。圖示例中，上述分開的部位是以平坦面9的平整面圖示，但上述分開的部位也可事先構成為施加有如圓筒面一部份之曲面形狀的倒角形狀。經由設有上述分開部位，能夠使咬合凹部5的開口緣5a的前端壁6的壁厚構成為更厚。As shown in Fig. 1 and Fig. 2(a) and Fig. 2(b), the front end edge 7 of the nip head 3 and the end edge 8a on the front end edge 7 side of the upper inclined surface 8 are formed separately. . In the illustrated example, the separated portion is illustrated as a flat surface of the flat surface 9, but the separated portion may be configured in advance to have a chamfered shape in which a curved surface portion such as a cylindrical surface is applied. By providing the above-described divided portion, the thickness of the front end wall 6 of the opening edge 5a of the engagement recess 5 can be made thicker.
另外，假設在咬合進行途中，即使咬合對方的咬合凸部4產生衝接於咬合頭部3的前端緣7之狀況，但因咬合頭部3的前端緣7至上部傾斜面8的端緣8a之間是形成分開的構成，所以就能夠防止咬合對方的咬合凸部4造成咬合頭部3的前端緣7部變形。In addition, it is assumed that the occipital convex portion 4 of the occlusal portion is flushed to the distal end edge 7 of the occlusal head 3 in the middle of the occlusion, but the distal end edge 7 of the occlusal head portion 3 to the end edge 8a of the upper inclined surface 8 Since a separate configuration is formed between them, it is possible to prevent the occlusal convex portion 4 of the occlusion from being deformed by the distal end edge 7 of the occlusion head 3.
第3圖中，圖示著第1圖所示金屬製單面鍊齒1安裝在沿著拉鍊布帶13側緣設置之芯線部的左右雙開式拉鍊平面圖。第1圖所示的金屬製單面鍊齒1形成開腳的左右腳部2、2間(第1圖中，圖示著腳部2、2夾緊固定在布帶後的腳部形狀)，***有拉鍊布帶13的芯線部，然後，使用夾緊固定用沖頭等從其外側面側推壓左右腳部2、2朝開腳寬度縮小方向進行夾緊。如此一來，就可使拉鍊布帶13夾入在左右腳部2、2間由左右腳部2、2夾持著，能夠使金屬製單面鍊齒1安裝在拉鍊布帶13。In the third drawing, a plan view of the left and right double-opening zipper in which the metal single-face fastener element 1 shown in Fig. 1 is attached to the core portion provided along the side edge of the fastener tape 13 is shown. The metal single-face fastener element 1 shown in Fig. 1 forms the left and right leg portions 2 and 2 between the legs (in the first figure, the shape of the leg after the leg portions 2, 2 are clamped and fixed to the tape) The core portion of the fastener tape 13 is inserted, and then the left and right leg portions 2, 2 are pressed from the outer side surface side by the clamp fixing punch or the like to be clamped in the direction in which the width of the opening is narrowed. In this way, the fastener tape 13 can be sandwiched between the left and right leg portions 2, 2 by the left and right leg portions 2, 2, and the metal single-sided fastener element 1 can be attached to the fastener tape 13.
如上述，藉由將本發明相關的金屬製單面鍊齒1以指定間隔植附在複數條、左右一對的拉鍊布帶13的布帶側緣部，就能夠製作出左右的拉鍊齒條17。再加上，在所獲得的拉鍊齒條17的鍊齒列插通第一拉頭14及第二拉頭15，接著在鍊齒列的滑動方向前後兩端部安裝上止具16a及下止具16b，就能夠製造出第3圖所示的左右雙開式拉鍊12。As described above, the metal single-side fastener elements 1 according to the present invention can be attached to the side edge portions of the plurality of left and right fastener tapes 13 at predetermined intervals, thereby producing left and right zipper racks. 17. Further, the first slider 14 and the second slider 15 are inserted into the element row of the obtained fastener stringer 17, and then the upper and lower ends 16a and the lower end are attached to the front and rear ends of the element row in the sliding direction. With the 16b, the left and right double-open zippers 12 shown in Fig. 3 can be manufactured.
上述製造所獲得的左右雙開式拉鍊12是透過將第一拉頭14朝向上止具16a的方向滑動，此外透過將第二拉頭15朝向下止具16b的方向滑動，就能夠使各金屬製單面鍊齒1的咬合凸部4適當嵌入在咬合對方前端的咬合凹部5內。接著，當以相反方向滑動第一拉頭14或第二拉頭15時，就能夠使咬合狀態分開。The left and right double-opening zippers 12 obtained by the above-described manufacturing are slid by the first slider 14 in the direction of the upper stopper 16a, and by sliding the second slider 15 in the direction of the lower stopper 16b, each metal can be made. The nip convex portion 4 of the single-face fastener element 1 is appropriately fitted in the nip recess 5 that engages the tip end of the other end. Then, when the first slider 14 or the second slider 15 is slid in the opposite direction, the occlusal state can be separated.
使用第4圖對從咬合凸部4側逐漸進行咬合的第二拉頭15的咬合狀態進行說明時，咬合時咬合凸部4-1是通過形成在咬合對方前端咬合凹部5-0的上部傾斜面8-0附近，就能夠***咬合凹部5-0內。再加上，於該咬合時，咬合頭部3-1是不會和接著要***在咬合頭部3-1的咬合凹部5-1內的咬合凸部4-2衝接，能夠順暢移動至咬合位置。When the occlusal state of the second slider 15 that is gradually engaged from the side of the nip portion 4 is described with reference to Fig. 4, the occlusal convex portion 4-1 is inclined by the upper portion formed at the distal end engaging occlusion portion 5-0 during the occlusion. Near the face 8-0, it can be inserted into the nip recess 5-0. Further, at the time of the engagement, the engaging head portion 3-1 is not flushed with the engaging convex portion 4-2 which is to be inserted into the engaging recess portion 5-1 of the engaging head portion 3-1, and can be smoothly moved to The bite position.
接著，咬合凹部5和前端緣7之間因形成有上部傾斜面8，所以逐漸***至咬合凹部5內的咬合凸部4就不會干涉到嵌入前端的咬合頭部3，再加上，下一個本身咬合頭部3也不會干涉到接著要逐漸***至本身咬合凹部5內的咬合凸部4，能夠順暢進行左右雙開式拉鍊12的封閉。Then, since the upper inclined surface 8 is formed between the nip concave portion 5 and the front end edge 7, the nip convex portion 4 that is gradually inserted into the nip concave portion 5 does not interfere with the nip head 3 that is fitted into the front end, and is added. The own occlusal head 3 does not interfere with the occlusal projection 4 which is then gradually inserted into the occlusion recess 5 itself, and the closing of the left and right double-open zippers 12 can be smoothly performed.
其次，又如第1圖所示，即使形成有上部傾斜面8但還是能夠事先將咬合凹部5的開口緣5a的前端壁6的壁厚構成為較厚，再加上，又能夠將下部傾斜面上下方向的長度構成為較長，因此，左右的金屬製單面鍊齒1為咬合狀態時即使承受有橫拉力等外力，還是能夠有效防止咬合凸部4或咬合凹部5的變形或破損。Further, as shown in Fig. 1, even if the upper inclined surface 8 is formed, the thickness of the front end wall 6 of the opening edge 5a of the engaging recess 5 can be made thick in advance, and the lower portion can be inclined. Since the length of the squeezing convex portion 4 or the nip concave portion 5 is prevented from being deformed even when an external force such as a lateral pulling force is applied to the left and right metal single-sided sprocket 1 in the occluded state.
如此一來，本發明的左右雙開式拉鍊12，就能夠確保有穩定的優越咬合強度。As a result, the left and right double-opening zippers 12 of the present invention can ensure stable and superior occlusion strength.
第3圖所示的左右雙開式拉鍊12是表示第一拉頭14和第二拉頭15成頭對頭相向配置的構成，但本發明的左右雙開式拉鍊12，也可事先形成為第一拉頭14和第二拉頭15成尾對尾相向配置的構成。The left and right double-opening zipper 12 shown in FIG. 3 is a configuration in which the first slider 14 and the second slider 15 are arranged to face each other in the head-to-head direction. However, the left and right double-opening zipper 12 of the present invention may be formed as the first pull in advance.
