Description
本發明是一種拉鏈，包括：一對帶，前後延伸且左右相向；一對鏈牙列，包含沿著一對帶的相向的側緣部被固定的多個鏈牙；以及至少一個拉頭，使一對鏈牙列嚙合及分離，且尤其是有關於一種拉頭的結構。The present invention is a zipper, comprising: a pair of belts extending front and rear and facing left and right; a pair of chain teeth, including a plurality of chain teeth fixed along the facing side edges of the pair of belts; and at least one slider, which enables the pair of chain teeth to engage and separate, and is particularly related to the structure of a slider.
如眾所周知般，拉鏈藉由使拉頭移動而使多個鏈牙嚙合或分離。而且，於嚙合或分離時，於拉頭內鏈牙彼此碰撞而產生摩擦。該摩擦成為使拉頭移動時的阻力。以後，將該阻力稱為拉頭的滑動阻力。As is well known, a zipper engages or disengages a plurality of chain elements by moving a slider. When engaging or disengaging, the chain elements collide with each other inside the slider, generating friction. This friction becomes resistance when the slider is moved. Hereinafter, this resistance is referred to as the sliding resistance of the slider.
於專利文獻1中揭示的被稱為鏈齒的鏈牙中，實施了用於減小拉頭的滑動阻力的改良。更詳細而言，如以下所述。專利文獻1中的拉鏈中，相對於前後延伸的一對牙鏈帶，一對拉頭以彼此的開閉方向相反地進行安裝。另外，拉鏈於考慮到拉頭的滑動阻力的基礎上，關於拉鏈延伸的前後方向，設想拉鏈的通常的開閉方向，來安裝拉頭。於專利文獻1中，其中一個拉頭關於前後方向而通常安裝，另一個拉頭關於前後方向與通常為逆向地安裝。而且，專利文獻1中所揭示的鏈齒減少（減小）與通常為逆向地安裝的拉頭的滑動阻力。以後，通常安裝的拉頭由於拉鏈的打開方式正常，因此稱為正開拉頭，逆向安裝的拉頭稱為逆開拉頭。 [現有技術文獻] [專利文獻] In the chain teeth called chain teeth disclosed in Patent Document 1, an improvement for reducing the sliding resistance of the slider is implemented. More specifically, it is as follows. In the zipper in Patent Document 1, a pair of sliders are installed in opposite opening and closing directions relative to a pair of chain tapes extending front and back. In addition, the slider is installed in the front and back direction of the zipper, taking into account the sliding resistance of the slider, and assuming the normal opening and closing direction of the zipper. In Patent Document 1, one of the sliders is installed normally with respect to the front and back direction, and the other slider is installed in the reverse direction with respect to the front and back direction. Furthermore, the chain teeth disclosed in Patent Document 1 reduce (reduce) the sliding resistance of the slider that is usually installed in the reverse direction. Hereinafter, the slider that is usually installed is called a normal opening slider because the zipper opens normally, and the slider that is installed in the reverse direction is called a reverse opening slider.

專利文獻1：日本專利實公平1-22505號公報Patent document 1: Japanese Patent Publication No. 1-22505
[發明所欲解決之課題] 如上所述，拉頭的滑動阻力是由拉頭內的鏈牙彼此的摩擦阻力而引起。專利文獻1中揭示的技術藉由改良鏈牙的形狀，來減小拉頭的滑動阻力。然而，為了減小拉頭的滑動阻力，認為不僅能夠藉由改良鏈牙的形狀，而且能夠藉由改良拉頭的形狀來實現。 [Problem to be solved by the invention] As described above, the sliding resistance of the slider is caused by the friction resistance between the chain teeth in the slider. The technology disclosed in Patent Document 1 reduces the sliding resistance of the slider by improving the shape of the chain teeth. However, in order to reduce the sliding resistance of the slider, it is believed that it can be achieved not only by improving the shape of the chain teeth, but also by improving the shape of the slider.
另外，拉頭的滑動阻力並非僅發生於逆開拉頭，亦發生於正開拉頭。而且，認為若可減小拉頭的滑動阻力，則設計者可較先前而言更自由地設計拉鏈。In addition, the sliding resistance of the slider occurs not only in the reverse opening slider, but also in the normal opening slider. Moreover, it is believed that if the sliding resistance of the slider can be reduced, the designer can design the zipper more freely than before.
本發明是考慮到所述實際情況創作而成，其目的在於提供一種減小拉頭的滑動阻力的拉頭。 [解決課題之手段] The present invention is created in consideration of the above-mentioned actual situation, and its purpose is to provide a slider that reduces the sliding resistance of the slider. [Means for solving the problem]
本發明的拉鏈包括：一對帶，前後延伸且左右相向；一對鏈牙列，包含沿著一對帶的相向的側緣部被固定的多個鏈牙；以及至少一個拉頭，使一對鏈牙列嚙合及分離。而且，全部的拉頭包括至少一個第一拉頭。第一拉頭包括：上下相向的上翼板及下翼板；連結柱，於使一對鏈牙列嚙合時於使第一拉頭移動的嚙合方向側將上翼板與下翼板連結；凸緣，自上翼板及下翼板向使兩者之間所形成的間隙變窄的方向突出且沿著上翼板及下翼板的左右緣部形成；以及鏈牙路，供一對鏈牙列通過，且形成於左右的凸緣及上翼板與下翼板之間。另外，鏈牙路包括：嚙合路，以左右的鏈牙嚙合的狀態通過；嚙合開始路，相對於嚙合路於嚙合方向側較嚙合路而言於左右方向上寬度寬且左右的鏈牙一邊碰撞一邊開始嚙合；以及一對分支路，相對於嚙合開始路於嚙合方向側向連結柱的左右分支。以上以本發明的拉鏈為前提。The zipper of the present invention includes: a pair of belts extending front and rear and facing left and right; a pair of chain teeth, including a plurality of chain teeth fixed along the facing side edges of the pair of belts; and at least one slider to engage and separate the pair of chain teeth. Moreover, all sliders include at least one first slider. The first slider includes: an upper wing plate and a lower wing plate facing each other up and down; a connecting column to connect the upper wing plate and the lower wing plate on the engaging direction side of moving the first slider when engaging the pair of chain teeth; a flange protruding from the upper wing plate and the lower wing plate in a direction to narrow the gap formed therebetween and formed along the left and right edges of the upper wing plate and the lower wing plate; and a chain tooth path for the pair of chain teeth to pass through, and formed between the left and right flanges and the upper wing plate and the lower wing plate. In addition, the chain tooth path includes: an engagement path, through which the left and right chain teeth pass in an engaged state; an engagement start path, which is wider in the left and right directions than the engagement path on the engagement direction side and the left and right chain teeth start to engage while colliding; and a pair of branch paths, which branch to the left and right of the connecting column on the engagement direction side relative to the engagement start path. The above is based on the zipper of the present invention.
而且，本發明中的第一態樣的拉鏈的特徵在於，至少一個凸緣包括凸部，所述凸部以使於嚙合開始路中與左或右相向的凸緣之間形成的間隔局部變窄的狀態突出，且減少嚙合開始過程中的鏈牙彼此的摩擦阻力。Moreover, the first aspect of the zipper of the present invention is characterized in that at least one flange includes a convex portion, which protrudes in a state where the interval formed between the flanges facing left or right in the engagement start path is locally narrowed, and reduces the frictional resistance between the chain teeth during the engagement start process.
為了減小第一拉頭的滑動阻力，理想的是如下所述。 即，至少兩個且左右相向的凸緣分別包括凸部。 In order to reduce the sliding resistance of the first slider, it is ideal to be as follows. That is, at least two left and right facing flanges each include a convex portion.
為了減小第一拉頭的滑動阻力，更理想的是如下所述。 即，所有的凸緣分別包括凸部。 In order to reduce the sliding resistance of the first slider, it is more desirable as follows. That is, all the flanges include convex portions, respectively.
第一拉頭的具體結構的一例包括如下所述。 即，凸緣將鏈牙路與外部左右劃分，使形成於朝向鏈牙路側的內表面與朝向外部側的外表面之間的厚度於凸部的位置處最厚，並且於嚙合路中的至少嚙合開始路側的端部為一定。 An example of a specific structure of the first slider includes the following. That is, the flange divides the chain path and the outside into left and right parts, so that the thickness formed between the inner surface facing the chain path and the outer surface facing the outside is the thickest at the position of the convex part, and is constant at least at the end of the engagement start path in the engagement path.
為了進一步減小第一拉頭的滑動阻力，理想的是如下所述。 至少一個凸緣於較凸部而言更靠嚙合方向側包括凹部，所述凹部以與左或右相向的凸緣之間所形成的間隔局部變寬的狀態凹陷，且減少嚙合開始過程中的鏈牙彼此的摩擦阻力。 In order to further reduce the sliding resistance of the first slider, it is desirable as follows. At least one ridge includes a recessed portion on the side closer to the engagement direction than the convex portion, and the recessed portion is recessed in a state where the interval formed between the ridges facing the left or right is partially widened, and the frictional resistance between the chain teeth in the process of starting engagement is reduced.
而且，本發明中的第二態樣的拉鏈的特徵在於，至少一個凸緣包括凹部，所述凹部以於嚙合開始路中與左或右相向的凸緣之間所形成的間隔局部變寬的狀態凹陷，且減少嚙合開始過程中的鏈牙彼此的摩擦阻力。Moreover, the second aspect of the zipper of the present invention is characterized in that at least one convex edge includes a recessed portion, which is recessed in a state where the interval formed between the left or right opposing convex edges in the engagement start path is locally widened, and reduces the frictional resistance between the chain teeth during the engagement start process.
為了減小第一拉頭的滑動阻力，理想的是如下所述。 即，至少兩個且左右相向的凸緣分別包括凹部。 In order to reduce the sliding resistance of the first slider, it is ideal to be as follows. That is, at least two left and right facing flanges each include a recessed portion.
為了減小第一拉頭的滑動阻力，理想的是如下所述。 即，所有的凸緣分別包括凹部。 In order to reduce the sliding resistance of the first slider, it is desirable as follows. That is, all the flanges include recesses, respectively.
第一拉頭的具體結構的一例包括如下所述。 凸緣將鏈牙路與外部左右劃分，使形成於朝向鏈牙路側的內表面與朝向外部側的外表面之間的厚度於嚙合路中的至少嚙合開始路側的端部為一定，於凹部中較嚙合路中的嚙合開始路側的端部而言薄。 An example of a specific structure of the first slider includes the following. The flange divides the chain path and the outside into left and right parts, so that the thickness formed between the inner surface facing the chain path and the outer surface facing the outside is constant at least at the end of the engagement start path in the engagement path, and is thinner than the end of the engagement start path in the engagement path in the recess.
關於拉鏈，無論鏈牙的形狀如何，於對於一對鏈牙列安裝相同結構的正開拉頭及逆開拉頭的情況下，有時拉頭的滑動阻力會產生差異，例如相對於正開拉頭而言逆開拉頭的滑動阻力大。於此種情況下，為了減小滑動阻力，有效的是應用本發明的第一態樣或第二態樣的拉鏈。而且，所謂滑動阻力產生差異的拉鏈的一例為如下所述。 即，拉鏈的鏈牙為前後不對稱形狀。 Regarding zippers, regardless of the shape of the chain teeth, when a straight-opening slider and a reverse-opening slider of the same structure are installed on a pair of chain teeth, the sliding resistance of the slider may be different. For example, the sliding resistance of the reverse-opening slider is greater than that of the straight-opening slider. In this case, in order to reduce the sliding resistance, it is effective to apply the first or second aspect of the present invention. Moreover, an example of a zipper with a difference in sliding resistance is as follows. That is, the chain teeth of the zipper are asymmetrical in front and back.
若鏈牙為前後不對稱形狀，則具體結構不受限。另外，拉鏈只要包括至少一個拉頭即可。而且，於拉頭使用前後不對稱形狀的鏈牙且包括一對拉頭的情況下，為了減小逆開拉頭的滑動阻力，理想的是如下所述。 即，拉鏈包括一對拉頭。而且，鏈牙包括：固定部，固定於帶；嚙合本體部，自固定部向帶相反側延伸；嚙合凸部，自嚙合本體部的前表面突出；以及嚙合凹部，於嚙合本體部的後表面凹陷。而且，一對拉頭中的其中一者是與第一拉頭不同的第二拉頭或第一拉頭，並且以自身的嚙合方向與嚙合凸部突出的方向一致的狀態安裝於一對鏈牙列。另外，一對拉頭中的另一者是第一拉頭，並且以自身的嚙合方向與嚙合凸部突出的方向成為相反的狀態安裝於一對鏈牙列。 [發明的效果] If the chain teeth are asymmetrical in shape in front and back, the specific structure is not limited. In addition, the zipper only needs to include at least one slider. Moreover, in the case where the slider uses a chain tooth with an asymmetrical shape in front and back and includes a pair of sliders, in order to reduce the sliding resistance of the reverse opening slider, it is ideal to be as follows. That is, the zipper includes a pair of sliders. Moreover, the chain teeth include: a fixing portion fixed to the belt; a gripping body portion extending from the fixing portion to the opposite side of the belt; a gripping convex portion protruding from the front surface of the gripping body portion; and a gripping concave portion recessed in the rear surface of the gripping body portion. Moreover, one of the pair of sliders is a second slider or a first slider different from the first slider, and is installed on a pair of chain teeth in a state where its own gripping direction is consistent with the protruding direction of the gripping convex portion. In addition, the other of the pair of sliders is a first slider, and is mounted on a pair of chain teeth in a state where its own engagement direction is opposite to the direction in which the engagement protrusion protrudes. [Effect of the invention]
本發明的拉鏈中，於凸緣在嚙合開始路中包括凸部的情況下，藉由使第一拉頭向嚙合方向移動，於沿著凸緣移動的鏈牙到達凸部時，該鏈牙以向相向的鏈牙的方向靠近的方式移動，因此與無凸部的拉頭相比，鏈牙彼此容易嚙合，可減小第一拉頭的滑動阻力。In the zipper of the present invention, when the flange includes a convex portion in the engagement start path, by moving the first slider in the engagement direction, when the chain teeth moving along the flange reach the convex portion, the chain teeth move in a manner approaching the opposite chain teeth. Therefore, compared with a slider without a convex portion, the chain teeth are easier to engage with each other, and the sliding resistance of the first slider can be reduced.
另外，本發明的拉鏈中，於凸緣在嚙合開始路中包括凹部的情況下，藉由使第一拉頭向嚙合方向移動，於沿著凸緣移動的鏈牙到達凹部時，該鏈牙向凹部的方向移動，以離開相向的鏈牙，因此除了緩和於凹部的位置處的鏈牙彼此的接觸以外，該鏈牙於移動至較凹部而言更靠嚙合路側時以向相向的鏈牙靠近的方式移動，因此與無凹部的拉頭相比，鏈牙彼此容易嚙合，可減小第一拉頭的滑動阻力。In addition, in the zipper of the present invention, when the convex edge includes a recessed portion in the engagement start path, by moving the first slider in the engagement direction, when the chain tooth moving along the convex edge reaches the recessed portion, the chain tooth moves in the direction of the recessed portion to leave the opposite chain tooth. Therefore, in addition to easing the contact between the chain teeth at the position of the recessed portion, the chain tooth moves in a manner approaching the opposite chain tooth when moving to the engagement path side closer to the recessed portion. Therefore, compared with a slider without a recessed portion, the chain teeth are easier to engage with each other, and the sliding resistance of the first slider can be reduced.
如圖1所示，本發明的第一實施方式的拉鏈1包括：一對牙鏈帶2，前後延伸且左右相向；以及一對拉頭3、3，能夠於一對牙鏈帶2的相向的側緣部中向前後移動，並且開閉一對牙鏈帶2。一對拉頭3開閉一對牙鏈帶2的方向相反。另外，於本實施方式中，一對拉頭3的基本結構相同，一部分結構不同。以後，於對一對拉頭3進行與結構的不同相關的說明的情況下，將其中一個拉頭3稱為第一拉頭3b，將另一個拉頭3稱為第二拉頭3a。即，第一拉頭3b與第二拉頭3a的結構不同。再者，所謂「相向的側緣部」於左側的牙鏈帶2的情況下是右側的緣部，於右側的牙鏈帶2的情況下是左側的緣部。As shown in FIG. 1 , the zipper 1 of the first embodiment of the present invention includes: a pair of toothed chain bands 2 extending forward and backward and facing left and right; and a pair of sliders 3, 3, which can move forward and backward in the facing side edges of the pair of toothed chain bands 2 and open and close the pair of toothed chain bands 2. The pair of sliders 3 open and close the pair of toothed chain bands 2 in opposite directions. In addition, in this embodiment, the basic structure of the pair of sliders 3 is the same, and a part of the structure is different. Hereinafter, when the pair of sliders 3 are explained in relation to differences in structure, one of the sliders 3 is referred to as the first slider 3b, and the other slider 3 is referred to as the second slider 3a. That is, the first slider 3b and the second slider 3a have different structures. The so-called "facing side edges" are the right edge in the case of the left-side tooth chain tape 2, and the left edge in the case of the right-side tooth chain tape 2.
於將拉鏈1置於平面的狀態下，方向如以下般規定。 所謂「左右方向」是排列一對牙鏈帶2的方向。所謂「左方向」，於圖1、圖2中是左方向。所謂「右方向」，於圖1、圖2中是右方向。 另外，所謂「前後方向」是於俯視的狀態下沿與一對牙鏈帶2相向的方向交叉的方向延伸的方向，於圖1、圖2中是一直線的方向，與左右方向正交。所謂「前方向」，於圖1、圖2中是上方向，於圖2中標註符號F。所謂「後方向」，於圖1、圖2中是下方向，於圖2中標註符號B。 所謂「嚙合方向」是於使一對鏈牙列5L嚙合時使拉頭3移動的方向，於圖1、圖2的第一拉頭3b中為後方向，於圖1、圖2的第二拉頭3a中為前方向。圖2中，標註符號C作為第二拉頭3a的嚙合方向，標註符號C1作為第一拉頭3b的嚙合方向。再者，於對鏈牙列5L或拉頭3的基本結構進行說明的情況下，拉頭3的嚙合方向以用於第二拉頭3a的嚙合方向中的符號C表述。 所謂「分離方向」是於使一對鏈牙列5L分離時使拉頭3移動的方向，於圖1、圖2的第一拉頭3b中為前方向，於圖1、圖2的第二拉頭3a中為後方向。圖2中標註S作為第二拉頭3a的分離方向，標註S1作為第一拉頭3b的分離方向。再者，於對鏈牙列5L或拉頭3的基本結構進行說明的情況下，分離方向以符號S表述。 所謂「上下方向」是與前後方向及左右方向正交的方向。所謂「上方向」是於圖1、圖2中與紙面正交的方向（與前後方向及左右方向正交的方向）中朝向近前側的方向。所謂「下方向」，於圖1、圖2中是相對於紙面正交的方向中朝向里側的方向。 When the zipper 1 is placed on a plane, the directions are defined as follows. The so-called "left-right direction" is the direction in which a pair of tooth chain tapes 2 are arranged. The so-called "left direction" is the left direction in Figures 1 and 2. The so-called "right direction" is the right direction in Figures 1 and 2. In addition, the so-called "front-back direction" is the direction extending in the direction intersecting the direction in which the pair of tooth chain tapes 2 face each other when viewed from above, and is the direction of a straight line in Figures 1 and 2, which is orthogonal to the left-right direction. The so-called "front direction" is the upper direction in Figures 1 and 2, and is marked with the symbol F in Figure 2. The so-called "rear direction" is the lower direction in Figures 1 and 2, and is marked with the symbol B in Figure 2. The so-called "engagement direction" is the direction in which the slider 3 moves when a pair of chain teeth 5L are engaged, which is the rear direction in the first slider 3b in Figures 1 and 2, and the front direction in the second slider 3a in Figures 1 and 2. In Figure 2, the reference symbol C is used as the engagement direction of the second slider 3a, and the reference symbol C1 is used as the engagement direction of the first slider 3b. Furthermore, when explaining the basic structure of the chain teeth 5L or the slider 3, the engagement direction of the slider 3 is expressed by the symbol C used in the engagement direction of the second slider 3a. The so-called "separation direction" is the direction in which the slider 3 moves when a pair of chain teeth 5L is separated, which is the front direction in the first slider 3b in Figures 1 and 2, and the rear direction in the second slider 3a in Figures 1 and 2. In Figure 2, the symbol S is used as the separation direction of the second slider 3a, and the symbol S1 is used as the separation direction of the first slider 3b. Furthermore, when explaining the basic structure of the chain teeth 5L or the slider 3, the separation direction is represented by the symbol S. The so-called "upward and downward direction" is a direction orthogonal to the front-rear direction and the left-right direction. The so-called "upward direction" is a direction toward the near front side in the direction orthogonal to the paper surface in Figures 1 and 2 (directions orthogonal to the front-rear direction and the left-right direction). The so-called "downward direction" in Figures 1 and 2 refers to the direction that is perpendicular to the paper surface and faces the inner side.
如圖1所示，一對牙鏈帶2包括：一對帶4，沿前後方向延伸且於左右方向上相向；一對鏈牙列5L，分別包含沿著一對帶4的相向的側緣部被固定的多個鏈牙5；打開件6，固定於一對帶4的前後方向的後端部；以及一對止擋件7，於與打開件6相反的一側分別固定於一對帶4的前端部。再者，亦可於一對帶4的前後方向的後端部設置止擋件7來代替打開件6。As shown in FIG. 1 , a pair of toothed chain bands 2 includes: a pair of bands 4 extending in the front-rear direction and facing each other in the left-right direction; a pair of chain tooth rows 5L, each including a plurality of chain teeth 5 fixed along the facing side edges of the pair of bands 4; an opening member 6 fixed to the rear end of the pair of bands 4 in the front-rear direction; and a pair of stoppers 7 fixed to the front end of the pair of bands 4 on the side opposite to the opening member 6. Furthermore, the stoppers 7 may be provided at the rear end of the pair of bands 4 in the front-rear direction instead of the opening member 6.
帶4為前後長的帶狀，其厚度方向為上下方向。The belt 4 is in the shape of a belt that is long from front to back, and its thickness direction is the up-down direction.
一對鏈牙列5L設為於前後方向上錯開一個鏈牙5的量的狀態下的左右對稱的形狀。鏈牙5於左右方向上包括：固定部51，於自厚度方向的兩側夾持帶4的狀態下固定於帶4；以及嚙合部52，自固定部51向與帶4相反的一側（以後，稱為「帶相反側」）突出且與其他鏈牙5嚙合。再者，將左右方向中與帶相反側相反的一側稱為「帶側」。A pair of chain element rows 5L is set to be symmetrical in the left-right direction in a state where they are staggered by one chain element 5 in the front-rear direction. The chain element 5 includes: a fixing portion 51 in the left-right direction, fixed to the belt 4 in a state where the belt 4 is clamped from both sides in the thickness direction; and an engaging portion 52, which protrudes from the fixing portion 51 to the side opposite to the belt 4 (hereinafter referred to as the "belt opposite side") and engages with other chain elements 5. In addition, the side opposite to the belt opposite side in the left-right direction is referred to as the "belt side".
嚙合部52於本實施方式中如圖2所示，於前後方向（拉頭3的嚙合方向C與分離方向S）為不對稱形狀，包括：嚙合本體部53，自固定部51向帶相反側延伸；嚙合凸部54，自嚙合本體部53的前表面突出；以及嚙合凹部55，於嚙合本體部53的後表面凹陷。鏈牙5的嚙合凸部54嵌合於另一鏈牙5的嚙合凹部55，鏈牙5的嚙合凹部55嵌合於另一鏈牙5的嚙合凸部54。於本實施方式中，嚙合凸部54突出的方向（前方向）與關閉一對牙鏈帶2時的拉頭3的移動方向一致的拉頭3為第二拉頭3a，亦稱為正開拉頭。另一個拉頭3為第一拉頭3b，亦稱為逆開拉頭。換言之，於本實施方式中，第二拉頭3a於自身的嚙合方向C與嚙合凸部54突出的方向一致的狀態下安裝於一對所述鏈牙列5L，第一拉頭3b於自身的嚙合方向C1與嚙合凸部54突出的方向為相反的狀態下安裝於一對鏈牙列5L。As shown in FIG. 2 , the engagement portion 52 in the present embodiment is asymmetrical in the front-rear direction (engagement direction C and separation direction S of the slider 3 ), and includes: an engagement body portion 53 extending from the fixing portion 51 to the opposite side of the belt; an engagement convex portion 54 protruding from the front surface of the engagement body portion 53; and an engagement concave portion 55 recessed in the rear surface of the engagement body portion 53. The engagement convex portion 54 of the chain tooth 5 is engaged with the engagement concave portion 55 of the other chain tooth 5 , and the engagement concave portion 55 of the chain tooth 5 is engaged with the engagement convex portion 54 of the other chain tooth 5 . In the present embodiment, the slider 3 whose protruding direction (forward direction) of the engaging protrusion 54 is consistent with the moving direction of the slider 3 when closing the pair of toothed chain bands 2 is the second slider 3a, also called the positive opening slider. The other slider 3 is the first slider 3b, also called the reverse opening slider. In other words, in the present embodiment, the second slider 3a is mounted on the pair of chain teeth 5L in a state where its own engaging direction C is consistent with the protruding direction of the engaging protrusion 54, and the first slider 3b is mounted on the pair of chain teeth 5L in a state where its own engaging direction C1 is opposite to the protruding direction of the engaging protrusion 54.
如圖1、圖2所示，拉頭3包括：拉頭主體30，嚙合及分離一對鏈牙列5L；以及拉片（未圖示），與拉頭主體30連結，並且用於使拉頭主體30移動時進行操作。As shown in FIG. 1 and FIG. 2 , the slider 3 includes: a slider body 30 that engages and disengages a pair of chain teeth 5L; and a pull tab (not shown) that is connected to the slider body 30 and is used to operate when the slider body 30 moves.
拉頭主體30包括：上翼板32及下翼板33，於上下方向上隔開間隔而相向；連結柱34，使上翼板32與下翼板33於相向的空間內在嚙合方向C側加以連結，且連結柱34夾持於一對鏈牙列5L之間；以及凸緣35，自上翼板32及下翼板33向使兩者之間所形成的間隙變窄的方向突出並且沿著上翼板32與下翼板33的左右緣部形成。再者，於本實施方式中，拉頭主體30包括自上翼板32的上表面突出的拉片安裝部31。拉片安裝部31與上翼板32協作而形成沿左右方向貫通的貫通孔（未圖示），將拉片的一端部與所述貫通孔連結。The slider body 30 includes: an upper wing plate 32 and a lower wing plate 33, which are spaced apart and face each other in the vertical direction; a connecting column 34, which connects the upper wing plate 32 and the lower wing plate 33 in the space facing each other in the engagement direction C, and the connecting column 34 is clamped between a pair of chain teeth 5L; and a flange 35, which protrudes from the upper wing plate 32 and the lower wing plate 33 in a direction to narrow the gap formed therebetween and is formed along the left and right edges of the upper wing plate 32 and the lower wing plate 33. Furthermore, in the present embodiment, the slider body 30 includes a pull-tab mounting portion 31 protruding from the upper surface of the upper wing plate 32. The pull-tab mounting portion 31 cooperates with the upper wing plate 32 to form a through hole (not shown) that penetrates in the left and right direction, and one end of the pull-tab is connected to the through hole.
另外，拉頭主體30包括鏈牙路36及一對帶槽37作為其內部空間，所述鏈牙路36形成於左右的凸緣35及上翼板32與下翼板33之間並且供一對鏈牙列5L通過，所述一對帶槽37形成於上下相向的凸緣35之間並且於與鏈牙路36連通的狀態下向左或右開口。一對鏈牙列5L通過鏈牙路36，相對應的一側的帶4通過各帶槽37。In addition, the slider body 30 includes a chain tooth path 36 and a pair of belt grooves 37 as its internal space. The chain tooth path 36 is formed between the left and right flanges 35 and the upper wing plate 32 and the lower wing plate 33 and allows a pair of chain tooth rows 5L to pass through. The pair of belt grooves 37 are formed between the upper and lower flanges 35 and open to the left or right when connected to the chain tooth path 36. The pair of chain tooth rows 5L pass through the chain tooth path 36, and the belt 4 on the corresponding side passes through each belt groove 37.
鏈牙路36的左右的外側被左右的凸緣35劃分。另外，鏈牙路36藉由連結柱34向左右分支成兩股且自連結柱34向分離方向S延伸成一條。更詳細而言，鏈牙路36包括：嚙合路361，以左右的鏈牙5於分離方向S側的部分中嚙合的狀態通過；嚙合開始路362，於相對於嚙合路361而言於嚙合方向C側較嚙合路361而言於左右方向上寬度寬，且使拉頭3向嚙合方向C移動的情況下，左右的鏈牙5一邊相互碰撞一邊開始嚙合；以及一對分支路363，相對於嚙合開始路362於嚙合方向C側（前側）向連結柱34的左右分支。The left and right outer sides of the chain path 36 are divided by the left and right flanges 35. In addition, the chain path 36 is branched into two branches to the left and right by the connecting post 34 and extends in a separation direction S from the connecting post 34. In more detail, the chain tooth path 36 includes: an engagement path 361, through which the left and right chain teeth 5 pass in an engaged state in a portion on the side of the separation direction S; an engagement start path 362, which is wider on the engagement direction C side relative to the engagement path 361 than the engagement path 361 in the left and right directions, and when the slider 3 moves in the engagement direction C, the left and right chain teeth 5 begin to engage while colliding with each other; and a pair of branch paths 363, which branch to the left and right of the connecting column 34 on the engagement direction C side (front side) relative to the engagement start path 362.
以上是拉頭3的基本結構，是第一拉頭3b與第二拉頭3a的共同結構。第二拉頭3a是標準的拉頭，第一拉頭3b是較標準的拉頭而言減小滑動阻力的特殊的拉頭。於本實施方式中，關於拉頭主體30的內部空間的形狀，第一拉頭3b與第二拉頭3a均設為上下對稱。以後，對作為第一拉頭3b與第二拉頭3a的不同結構的凸緣35、及基於凸緣35的形狀的鏈牙路36進行說明。The above is the basic structure of the slider 3, which is a common structure of the first slider 3b and the second slider 3a. The second slider 3a is a standard slider, and the first slider 3b is a special slider that reduces the sliding resistance compared to the standard slider. In this embodiment, the shape of the internal space of the slider body 30 is set to be vertically symmetrical. Hereinafter, the flange 35 as the different structure of the first slider 3b and the second slider 3a, and the chain tooth path 36 based on the shape of the flange 35 will be described.
關於第二拉頭3a，凸緣35是沿著上翼板32或下翼板33的左邊緣部或右邊緣部延伸的凸緣本體351。凸緣35除了嚙合方向C的端部以外，使形成於內表面355與外表面356之間的厚度為一定。凸緣35的嚙合方向C的端部設為宛如倒角的形狀，換言之，設為隨著朝向前端而較該一定的厚度而言變薄的前端變細的形狀。更詳細而言如以下所述。Regarding the second slider 3a, the flange 35 is a flange body 351 extending along the left edge or the right edge of the upper wing plate 32 or the lower wing plate 33. The flange 35 has a constant thickness formed between the inner surface 355 and the outer surface 356 except for the end in the engagement direction C. The end in the engagement direction C of the flange 35 is set to a shape like a chamfer, in other words, a shape in which the front end becomes thinner than the constant thickness as it approaches the front end. More details are as follows.
與第一拉頭3b及第二拉頭3a無關，凸緣35將鏈牙路36及外部左右劃分。而且，凸緣35包括朝向鏈牙路36側的內表面355及朝向外部側的外表面356。順便一提，於圖2中，拉頭主體30的下側部分包括凸緣35在內示出。Regardless of the first slider 3b and the second slider 3a, the flange 35 divides the chain path 36 and the outside into left and right parts. Moreover, the flange 35 includes an inner surface 355 facing the chain path 36 and an outer surface 356 facing the outside. By the way, in FIG. 2 , the lower part of the slider body 30 including the flange 35 is shown.
關於第二拉頭3a，左右相向的一對凸緣35的外表面356中，使與嚙合路361對應的部分於前後方向上平行，使與嚙合開始路362對應的部分於分離方向S的端部以外的位置隨著朝向嚙合方向C而逐漸於左右方向上變寬。更具體而言，左右相向的一對凸緣35的外表面356中，使與嚙合開始路362對應的部分形成為於嚙合方向C的端部以外的位置呈弧狀凹陷的形狀。再者，關於第一拉頭3b，左右相向的一對凸緣35的外表面356亦與第二拉頭3a相同。Regarding the second slider 3a, the portion corresponding to the engagement path 361 of the outer surface 356 of the pair of flanges 35 facing left and right is made parallel in the front-rear direction, and the portion corresponding to the engagement start path 362 is made gradually wider in the left-right direction at a position other than the end of the separation direction S as it moves toward the engagement direction C. More specifically, the portion corresponding to the engagement start path 362 of the outer surface 356 of the pair of flanges 35 facing left and right is formed into an arc-shaped concave shape at a position other than the end of the engagement direction C. Furthermore, regarding the first slider 3b, the outer surface 356 of the pair of flanges 35 facing left and right is also the same as that of the second slider 3a.
關於第二拉頭3a，左右相向的一對凸緣35的內表面355中，使與嚙合路361對應的部分於前後方向上平行，使與嚙合開始路362對應的部分於分離方向S的端部以外的位置隨著朝向嚙合方向C而逐漸於左右方向上變寬。更具體而言，左右相向的一對凸緣35的內表面355中，使與嚙合開始路362對應的部分形成為於嚙合方向C的端部以外的位置較與第二拉頭3a的左右相向的一對凸緣35的外表面356平緩地呈弧狀膨脹的形狀。再者，凸緣35的內表面355呈弧狀膨脹的形狀、凸緣35的外表面356呈弧狀凹陷的形狀是基於視點的不同，且同樣地彎曲。Regarding the second slider 3a, the portion corresponding to the engagement path 361 of the inner surface 355 of the pair of flanges 35 facing left and right is made parallel in the front-rear direction, and the portion corresponding to the engagement start path 362 is made gradually wider in the left-right direction at a position other than the end of the separation direction S as it moves toward the engagement direction C. More specifically, the portion corresponding to the engagement start path 362 of the inner surface 355 of the pair of flanges 35 facing left and right is formed into a shape that expands smoothly in an arc shape compared with the outer surface 356 of the pair of flanges 35 facing left and right of the second slider 3a at a position other than the end of the engagement direction C. Furthermore, the shape of the inner surface 355 of the flange 35 expanding in an arc shape and the shape of the outer surface 356 of the flange 35 concave in an arc shape are based on the difference in viewpoints and are similarly curved.
關於第二拉頭3a，嚙合路361於前後方向上平行，左右寬度為一定。於圖示的例子中，嚙合路361於遍及一對鏈牙列5L的通過方向（前後方向）的總長度上左右的寬度為一定，但亦可為於分離方向S側的端部隨著朝向分離方向S而變寬的形狀。另外，嚙合開始路362隨著朝向嚙合方向C而向左右兩側變寬（左右的寬度變寬）。因此，嚙合路361與嚙合開始路362之間的邊界由鏈牙路36的左右寬度規定（參照圖3）。另外，一對分支路363是相對於連結柱34位於左右的部分。於圖示的例子中，凸緣35除了嚙合方向C的端部以外，使形成於內表面355與外表面356之間的厚度為一定。Regarding the second slider 3a, the engagement path 361 is parallel in the front-to-back direction and has a constant width on the left and right. In the illustrated example, the engagement path 361 has a constant width on the left and right over the total length of the passing direction (front-to-back direction) of a pair of chain tooth rows 5L, but it may also be a shape in which the end on the separation direction S side widens as it moves toward the separation direction S. In addition, the engagement start path 362 widens to the left and right sides (the width on the left and right widens) as it moves toward the engagement direction C. Therefore, the boundary between the engagement path 361 and the engagement start path 362 is defined by the left and right width of the chain tooth path 36 (refer to FIG. 3). In addition, a pair of branch paths 363 are portions located on the left and right relative to the connecting column 34. In the example shown in the figure, the flange 35 has a constant thickness formed between the inner surface 355 and the outer surface 356 except for the end portion in the engagement direction C.
關於第一拉頭3b，凸緣35包括：沿著上翼板32或下翼板33的左邊緣部或右邊緣部延伸的凸緣本體351；以及相對於凸緣本體351的內表面355突出的凸部352或者相對於凸緣本體351的內表面355凹陷的凹部353。凸部352與凹部353均減少嚙合開始過程中的鏈牙5彼此的摩擦阻力。Regarding the first slider 3b, the flange 35 includes: a flange body 351 extending along the left edge or the right edge of the upper wing plate 32 or the lower wing plate 33; and a convex portion 352 protruding relative to the inner surface 355 of the flange body 351 or a concave portion 353 recessed relative to the inner surface 355 of the flange body 351. Both the convex portion 352 and the concave portion 353 reduce the friction resistance between the chain teeth 5 in the process of starting engagement.
凸部352以使於嚙合開始路362中與左或右相向的凸緣35之間所形成的間隔局部變窄的狀態突出。 凹部353以於嚙合開始路362中與左或右相向的凸緣35之間所形成的間隔局部變寬的狀態凹陷。 所謂局部，是僅與特定的一部分相關的情況。因此，凸部352及凹部353僅形成於凸緣35中的嚙合開始路362的一部分，而不會形成於整體中。 圖2中示出第一拉頭3b的下側部分，左邊的凸緣35包括凸部352，右邊的凸緣35包括凹部353。第一拉頭3b為上下對稱，因此於第一拉頭3b的上側亦為左邊的凸緣35包括凸部352，右邊的凸緣35包括凹部353。 The convex portion 352 protrudes in a state where the interval formed between the flanges 35 facing the left or right in the engagement start path 362 is partially narrowed. The concave portion 353 is recessed in a state where the interval formed between the flanges 35 facing the left or right in the engagement start path 362 is partially widened. The so-called local refers to a situation related only to a specific part. Therefore, the convex portion 352 and the concave portion 353 are formed only in a part of the engagement start path 362 in the flange 35, and are not formed in the whole. FIG. 2 shows the lower side portion of the first slider 3b, where the flange 35 on the left includes the convex portion 352, and the flange 35 on the right includes the concave portion 353. The first slider 3b is symmetrical in vertical direction, so the left flange 35 on the upper side of the first slider 3b includes a convex portion 352, and the right flange 35 includes a concave portion 353.
關於第一拉頭3b，凸緣35除了嚙合方向C1的端部、凸部352及凹部353的部分以外，使形成於內表面355與外表面356之間的厚度為一定。於圖示的例子中，使凸緣35的該厚度形成為一定的範圍是較凸部352而言更靠分離方向S1側的總長度，但理想的是於嚙合路361中的至少嚙合開始路362側的端部，為鏈牙路36中的至少與凸部352對應的範圍的長度以上。凸緣35的嚙合方向C1的端部是與第二拉頭3a相同的結構。更詳細而言為以下所述。Regarding the first slider 3b, the flange 35 has a constant thickness formed between the inner surface 355 and the outer surface 356, except for the end portion in the engagement direction C1, the convex portion 352, and the concave portion 353. In the example shown in the figure, the range in which the thickness of the flange 35 is formed constant is the total length on the separation direction S1 side relative to the convex portion 352, but it is ideal that the end portion on the engagement start path 362 side in the engagement path 361 is at least the length of the range corresponding to the convex portion 352 in the chain tooth path 36. The end portion in the engagement direction C1 of the flange 35 is the same structure as the second slider 3a. More details are as follows.
如圖3所示，凸部352相對於嚙合開始路362中的與嚙合路361的邊界於嚙合方向C1側隔開間隔地配置。凹部353於嚙合開始路362中配置於較凸部352而言更靠嚙合方向C1側。另外，凹部353配置於較凸緣35的嚙合開始路362側的前端而言更靠分離方向S1側。凸部352為呈弧狀膨脹的形狀，凹部353為呈弧狀凹陷的形狀。另外，凸部352與凹部353形成為，於鏈牙5彼此嚙合時，嚙合的兩個鏈牙5的固定部51同時位於凸部352及凹部353。As shown in FIG. 3 , the convex portion 352 is arranged at a distance from the boundary with the engagement path 361 in the engagement start path 362 on the engagement direction C1 side. The concave portion 353 is arranged in the engagement start path 362 on the engagement direction C1 side relative to the convex portion 352. In addition, the concave portion 353 is arranged on the separation direction S1 side relative to the front end of the flange 35 on the engagement start path 362 side. The convex portion 352 is in an arc-shaped bulged shape, and the concave portion 353 is in an arc-shaped sunken shape. In addition, the convex portion 352 and the concave portion 353 are formed so that when the chain teeth 5 are engaged with each other, the fixing portions 51 of the two engaged chain teeth 5 are simultaneously located on the convex portion 352 and the concave portion 353.
關於第一拉頭3b，左右相向的一對凸緣35的內表面355中，使與嚙合路361對應的部分於前後方向上平行，使與嚙合開始路362對應的部分於分離方向S1的端部、凸部352及凹部353以外的位置隨著朝向嚙合方向C1而逐漸於左右方向上變寬。更具體而言，左右相向的一對凸緣35的內表面355中，使與嚙合開始路362對應的部分形成為於分離方向S1的端部、凸部352及凹部353以外的位置呈弧狀且較與第二拉頭3a的左右相向的一對凸緣35的外表面356而言平緩地呈弧狀膨脹的形狀。因此，凸部352與凹部353相對於凸緣35的呈弧狀膨脹的形狀的設想的內表面355突出或凹陷。Regarding the first slider 3b, the portion corresponding to the engagement path 361 of the inner surface 355 of the pair of flanges 35 facing each other is parallel in the front-rear direction, and the portion corresponding to the engagement start path 362 is gradually widened in the left-right direction at the end of the separation direction S1, the convex portion 352, and the concave portion 353, as it moves toward the engagement direction C1. More specifically, the portion corresponding to the engagement start path 362 of the inner surface 355 of the pair of flanges 35 facing each other is formed into an arc shape at the end of the separation direction S1, the convex portion 352, and the concave portion 353, and is formed into a shape that expands in an arc shape more smoothly than the outer surface 356 of the pair of flanges 35 facing each other of the second slider 3a. Therefore, the protrusion 352 and the recess 353 are protruded or recessed relative to the imaginary inner surface 355 of the flange 35 that is in an arc-shaped expanded shape.
打開件6與止擋件7規定一對拉頭3的前後方向上的移動範圍。 如圖1所示，打開件6包含一對打開件片61、62，該一對打開件片61、62於一對帶4的前後方向上的後端部以相對於鏈牙列5L於後側相鄰的狀態分別被固定。於本實施方式中，其中一個打開件片61是固定於其中一個帶4的相向的側緣部的插棒61，另一個打開件片62是固定於另一個帶4的相向的側緣部的座棒62。座棒62構成為以不使第一拉頭3b脫落的方式與第一拉頭3b碰撞。另一方面，於將第一拉頭3b與第二拉頭3a以前後相鄰的狀態配置於其中一個鏈牙列5L的後端部的情況下，插棒61能夠相對於第二拉頭3a及第一拉頭3b的鏈牙路36的左右的單側插拔。 再者，止擋件7是以不使第二拉頭3a脫落的方式碰撞的結構。 The opening piece 6 and the stopper 7 define the range of movement of a pair of sliders 3 in the front-rear direction. As shown in FIG1 , the opening piece 6 includes a pair of opening piece pieces 61 and 62, which are respectively fixed at the rear end portions of a pair of belts 4 in the front-rear direction in a state of being adjacent to the chain tooth row 5L at the rear side. In this embodiment, one of the opening piece pieces 61 is an insert rod 61 fixed to the opposite side edge of one of the belts 4, and the other opening piece piece 62 is a seat rod 62 fixed to the opposite side edge of the other belt 4. The seat rod 62 is configured to collide with the first slider 3b in a manner that does not cause the first slider 3b to fall off. On the other hand, when the first slider 3b and the second slider 3a are arranged at the rear end of one of the chain tooth rows 5L in a state of being adjacent to each other in the front and rear, the insert rod 61 can be inserted and removed from the left and right sides of the chain tooth path 36 of the second slider 3a and the first slider 3b. Furthermore, the stopper 7 is a structure that collides in a way that does not cause the second slider 3a to fall off.
第一實施方式的拉鏈1中，由於第一拉頭3b的左側的凸緣35於嚙合開始路362中包括凸部352，因此藉由使第一拉頭3b向自身的嚙合方向C1移動，於沿著右側的凸緣35移動的鏈牙5到達了凸部352時該鏈牙5以向相向的鏈牙5的方向靠近的方式移動，因此與無凸部352的拉頭相比，鏈牙5彼此容易嚙合，可減少嚙合開始過程中的鏈牙5彼此的摩擦阻力，可減小第一拉頭3b的滑動阻力。In the zipper 1 of the first embodiment, since the flange 35 on the left side of the first slider 3b includes a convex portion 352 in the engagement start path 362, the first slider 3b is moved in its own engagement direction C1, and when the chain tooth 5 moving along the flange 35 on the right side reaches the convex portion 352, the chain tooth 5 moves in a manner approaching the opposite chain tooth 5. Therefore, compared with the slider without the convex portion 352, the chain teeth 5 are easier to engage with each other, which can reduce the friction resistance between the chain teeth 5 in the engagement start process, and reduce the sliding resistance of the first slider 3b.
另外，第一實施方式的拉鏈1中，由於第一拉頭3b的右側的凸緣35於嚙合開始路362中包括凹部353，因此藉由使第一拉頭3b向自身的嚙合方向C1移動，於沿著左側的凸緣35移動的鏈牙5到達凹部353時，該鏈牙5以離開相向的鏈牙5的方式向凹部353的方向移動，因此除了凹部353的位置處的鏈牙5彼此的接觸得到緩和以外，以於該鏈牙5到達較凹部353而言更靠嚙合路361側時向相向的鏈牙5的方向靠近的方式移動，因此與無凹部353的拉頭相比，鏈牙5彼此容易嚙合，可減少嚙合開始過程中的鏈牙5彼此的摩擦阻力，可減小第一拉頭3b的滑動阻力。In the zipper 1 of the first embodiment, since the flange 35 on the right side of the first slider 3b includes a recess 353 in the engagement start path 362, when the first slider 3b moves in its own engagement direction C1, when the chain tooth 5 moving along the flange 35 on the left side reaches the recess 353, the chain tooth 5 moves in the direction of the recess 353 in a manner away from the opposite chain tooth 5, In addition to easing the contact between the chain teeth 5 at the position of the recess 353, the chain teeth 5 move toward the opposite chain teeth 5 when they reach the side of the engagement path 361 that is closer to the recess 353. Therefore, compared with a slider without a recess 353, the chain teeth 5 are easier to engage with each other, which can reduce the friction resistance between the chain teeth 5 in the initial process of engagement and reduce the sliding resistance of the first slider 3b.
另外，第一實施方式的拉鏈1中，由於凸部352與凹部353均為弧狀，因此藉由使第一拉頭3b向自身的嚙合方向C1移動，於鏈牙5到達凹部353或凸部352時，該鏈牙5沿著弧狀平滑地移動，以靠近或遠離相向的鏈牙5，因此可減小第一拉頭3b的滑動阻力。In addition, in the zipper 1 of the first embodiment, since the protrusion 352 and the recess 353 are both arc-shaped, by moving the first slider 3b in its own engagement direction C1, when the chain tooth 5 reaches the recess 353 or the protrusion 352, the chain tooth 5 moves smoothly along the arc to approach or move away from the opposite chain tooth 5, thereby reducing the sliding resistance of the first slider 3b.
另外，第一實施方式的拉鏈1中，由於第一拉頭3b於較凸部352而言更靠自身的嚙合方向C1側包括凹部353，因此與僅包括凸部352的拉頭相比，可減小第一拉頭3b的滑動阻力，藉由使第一拉頭3b向自身的嚙合方向C1移動，於位於凹部353的鏈牙5到達較凹部353而言更靠嚙合路361側時，以向相向的鏈牙5的方向靠近的方式移動，因此與無凹部353的拉頭相比，鏈牙5彼此容易嚙合，可減小第一拉頭3b的滑動阻力。特別是，第一實施方式的拉鏈1中，由於將凸部352與凹部353的位置關係設為於一對鏈牙列5L的鏈牙5嚙合時嚙合的兩個鏈牙5的固定部51同時位於凸部352與凹部353的關係，因此例如與將凸部352與凹部353的位置關係形成為嚙合的兩個鏈牙5的固定部51於不同的時期位於凸部352與凹部353的關係的拉頭相比，鏈牙5彼此容易嚙合，可減小第一拉頭3b的滑動阻力。In addition, in the zipper 1 of the first embodiment, since the first slider 3b includes the recessed portion 353 on the side closer to its own engagement direction C1 than the protruding portion 352, the sliding resistance of the first slider 3b can be reduced compared to a slider including only the protruding portion 352. By moving the first slider 3b in its own engagement direction C1, when the chain tooth 5 located in the recessed portion 353 reaches the side closer to the engagement path 361 than the recessed portion 353, it moves in a manner approaching the direction of the opposing chain tooth 5. Therefore, compared with a slider without the recessed portion 353, the chain teeth 5 are easier to engage with each other, and the sliding resistance of the first slider 3b can be reduced. In particular, in the zipper 1 of the first embodiment, since the positional relationship between the protrusion 352 and the recessed portion 353 is set so that when the chain teeth 5 of a pair of chain tooth rows 5L are engaged, the fixed portions 51 of the two engaged chain teeth 5 are simultaneously located in the relationship between the protrusion 352 and the recessed portion 353. Therefore, compared with a slider in which the positional relationship between the protrusion 352 and the recessed portion 353 is formed so that the fixed portions 51 of the two engaged chain teeth 5 are located in the relationship between the protrusion 352 and the recessed portion 353 at different times, the chain teeth 5 are easily engaged with each other, and the sliding resistance of the first slider 3b can be reduced.
另外，第一實施方式的拉鏈1中，使形成於第一拉頭3b的凸緣35的朝向鏈牙路36側的內表面355與朝向外部側的外表面356之間的厚度於嚙合路361中的至少嚙合開始路362側的端部為一定，因此使第一拉頭3b向自身的嚙合方向C1移動時的鏈牙5彼此的嚙合得到保持。而且，使凸緣35的該厚度於凸部352的位置處最厚，因此例如與具有厚度於凸部352的位置處和嚙合路361中的嚙合開始路362側的端部相同的凸緣35的拉頭相比，第一拉頭3b的剛性亦得到提高。另外，由於使凸緣35的該厚度於凹部353的位置處較嚙合路361中的至少嚙合開始路362側的端部而言薄，因此例如與包括厚度於凹部353的位置處和嚙合路361中的嚙合開始路362側的端部相同的凸緣35（無凹部353的凸緣35）的拉頭相比，雖然減弱了第一拉頭3b的剛性，但與包括無凹部353的凸緣35的拉頭相比，鏈牙5難以於凹部353發生碰撞，因此可盡可能地抑制第一拉頭3b的剛性的下降。In the slide fastener 1 of the first embodiment, the thickness between the inner surface 355 of the flange 35 formed on the first slider 3b facing the tooth path 36 and the outer surface 356 facing the outside is constant at least at the end on the side of the engagement start path 362 in the engagement path 361, so that the engagement of the teeth 5 is maintained when the first slider 3b moves in its own engagement direction C1. In addition, the thickness of the flange 35 is the thickest at the position of the convex portion 352, so that, for example, the rigidity of the first slider 3b is improved compared to a slider having a flange 35 having the same thickness at the position of the convex portion 352 and at the end on the side of the engagement start path 362 in the engagement path 361. In addition, since the thickness of the flange 35 is made thinner at the position of the recess 353 than at least the end portion on the side of the engagement start path 362 in the engagement path 361, for example, compared with a slider including a flange 35 having the same thickness at the position of the recess 353 and at the end portion on the side of the engagement start path 362 in the engagement path 361 (a flange 35 without the recess 353), although the rigidity of the first slider 3b is weakened, the chain tooth 5 is less likely to collide with the recess 353 than with the slider including the flange 35 without the recess 353, so the reduction in the rigidity of the first slider 3b can be suppressed as much as possible.
另外，於第一實施方式的拉鏈1中，由於鏈牙5於前後（嚙合方向C及分離方向S）為不對稱形狀，因此即便一對拉頭3（正開拉頭及逆開拉頭）使用例如相同結構的拉頭，其中一個拉頭3的滑動阻力與另一個拉頭3的滑動阻力亦會產生差異。而且，已知於正開拉頭與逆開拉頭使用相同結構的拉頭的情況下，逆開拉頭較正開拉頭而言拉頭3的滑動阻力大。其原因如以下般推測。於關閉拉頭3時，鏈牙5沿著嚙合開始路362的內表面355移動。而且，隨著關閉拉頭3的操作，於逆開拉頭的情況下，鏈牙5的嚙合凸部54較嚙合本體部53而言先向逆開拉頭的嚙合路361突入。另一方面，隨著關閉拉頭3的操作，於正開拉頭的情況下，鏈牙5的嚙合本體部53較嚙合凸部54而言先向正開拉頭的嚙合路361突入。若如此，則推測：逆開拉頭較正開拉頭而言，先向嚙合路361突入嚙合凸部54的量，於嚙合開始路362中多個鏈牙5容易接近，接觸的鏈牙5的數量變多，或者於其中一個鏈牙5的嚙合凸部54越過另一個鏈牙5的嚙合凹部55的緣部時接觸的情況變得更強。In addition, in the zipper 1 of the first embodiment, since the chain teeth 5 are asymmetrical in front and back (engagement direction C and separation direction S), even if a pair of sliders 3 (a normal opening slider and a reverse opening slider) use sliders of the same structure, for example, the sliding resistance of one slider 3 and the sliding resistance of the other slider 3 will also be different. Moreover, it is known that when the normal opening slider and the reverse opening slider use sliders of the same structure, the sliding resistance of the slider 3 of the reverse opening slider is greater than that of the normal opening slider. The reason is estimated as follows. When the slider 3 is closed, the chain teeth 5 move along the inner surface 355 of the engagement start path 362. Moreover, with the operation of closing the slider 3, in the case of the reverse opening slider, the engaging protrusion 54 of the chain tooth 5 first penetrates into the engaging path 361 of the reverse opening slider than the engaging body 53. On the other hand, with the operation of closing the slider 3, in the case of the normal opening slider, the engaging body 53 of the chain tooth 5 first penetrates into the engaging path 361 of the normal opening slider than the engaging protrusion 54. If so, it is speculated that: for the reverse opening slider, the amount of the engaging protrusion 54 that first protrudes into the engaging path 361 is greater than that of the straight opening slider, and multiple chain teeth 5 are easily accessible in the engaging starting path 362, and the number of contacted chain teeth 5 increases, or when the engaging protrusion 54 of one chain tooth 5 passes over the edge of the engaging recess 55 of another chain tooth 5, the contact becomes stronger.
而且，第一實施方式的拉鏈1中，由於逆開拉頭使用包括凹部353或凸部352的第一拉頭3b，因此例如與逆開拉頭使用第二拉頭3a的情況相比，可減小逆開拉頭的滑動阻力。另外，於第一實施方式的拉鏈1中，由於鏈牙5於拉頭3的前後為不對稱形狀，因此例如於正開拉頭及逆開拉頭使用了相同結構的拉頭3的拉鏈的情況下，正開拉頭與逆開拉頭的滑動阻力產生差異。但是，第一實施方式的拉鏈1中，由於正開拉頭使用無凹部353或凸部352的第二拉頭3a，逆開拉頭使用包括凹部353或凸部352的第一拉頭3b，因此例如與正開拉頭及逆開拉頭此兩者使用第二拉頭3a的情況相比，滑動阻力的差異減小。Moreover, in the zipper 1 of the first embodiment, since the reverse opening slider uses the first slider 3b including the concave portion 353 or the convex portion 352, the sliding resistance of the reverse opening slider can be reduced, for example, compared with the case where the reverse opening slider uses the second slider 3a. In addition, in the zipper 1 of the first embodiment, since the chain teeth 5 are asymmetrical in shape in front and behind the slider 3, for example, in the case of a zipper using the slider 3 of the same structure for the forward opening slider and the reverse opening slider, the sliding resistance of the forward opening slider and the reverse opening slider is different. However, in the zipper 1 of the first embodiment, since the forward opening slider uses the second slider 3a without the recessed portion 353 or the protrusion 352, and the reverse opening slider uses the first slider 3b including the recessed portion 353 or the protrusion 352, the difference in sliding resistance is reduced compared to the case where both the forward opening slider and the reverse opening slider use the second slider 3a.
另外，第一實施方式的拉鏈1中，將第一拉頭3b與第二拉頭3a的凸緣35的外表面356、進而來說第一拉頭3b與第二拉頭3a的外觀設為相同的形態，因此可使使用者於不會注意到第一拉頭3b與第二拉頭3a的結構的不同的同時減小第一拉頭3b的滑動阻力。In addition, in the zipper 1 of the first embodiment, the outer surface 356 of the flange 35 of the first slider 3b and the second slider 3a, and further the appearance of the first slider 3b and the second slider 3a are set to the same shape, so that the user will not notice the difference in structure between the first slider 3b and the second slider 3a while reducing the sliding resistance of the first slider 3b.
如圖4所示，本發明的第二實施方式的拉鏈1a的鏈牙5a與第一實施方式的拉鏈1中的鏈牙5不同。鏈牙5a於前後方向（第一拉頭3b的嚙合方向C1與分離方向S1）上為對稱形狀。更詳細而言為以下所述。 對於鏈牙5a於左右方向上包括固定部51、以及與另一鏈牙5a嚙合的嚙合部52a的情況，與第一實施方式中的鏈牙5相同。其中，嚙合部52a包括：頸部56，自固定部51向帶相反側延伸且沿前後方向縮窄；頭部57，相對於頸部56向帶相反側延伸且沿前後方向膨脹；一對肩部58，自固定部51朝向頸部56的前後延伸；以及肩槽部（未圖示），為了收容肩部58而形成於頭部57。肩槽部形成於頭部57的前表面及後表面。 As shown in FIG. 4 , the chain teeth 5a of the zipper 1a of the second embodiment of the present invention are different from the chain teeth 5 in the zipper 1 of the first embodiment. The chain teeth 5a are symmetrical in the front-back direction (the engagement direction C1 and the separation direction S1 of the first slider 3b). More details are as follows. The case where the chain teeth 5a include a fixing portion 51 and an engagement portion 52a that engages with another chain tooth 5a in the left-right direction is the same as the chain teeth 5 in the first embodiment. The engaging portion 52a includes: a neck portion 56 extending from the fixing portion 51 to the opposite side of the belt and narrowing in the front-to-back direction; a head portion 57 extending to the opposite side of the belt relative to the neck portion 56 and expanding in the front-to-back direction; a pair of shoulders 58 extending from the fixing portion 51 to the front and back of the neck portion 56; and a shoulder groove portion (not shown) formed in the head portion 57 to accommodate the shoulder portion 58. The shoulder groove portion is formed on the front and rear surfaces of the head portion 57.
第二實施方式的拉鏈1a的鏈牙5a於前後方向上為對稱形狀，但即便於相對於此種鏈牙5a使用了具有凸部352或凹部353的第一拉頭3b的情況下，亦可藉由凸部352與凹部353減小第一拉頭3b的滑動阻力。再者，由於鏈牙5a於前後方向上為對稱形狀，因此例如即便正開拉頭與逆開拉頭使用相同的拉頭，正開拉頭與逆開拉頭的滑動阻力亦相同。The chain teeth 5a of the zipper 1a of the second embodiment are symmetrical in the front-to-back direction, but even if the first slider 3b having the convex portion 352 or the concave portion 353 is used for such chain teeth 5a, the sliding resistance of the first slider 3b can be reduced by the convex portion 352 and the concave portion 353. Furthermore, since the chain teeth 5a are symmetrical in the front-to-back direction, for example, even if the same slider is used for the forward opening slider and the reverse opening slider, the sliding resistance of the forward opening slider and the reverse opening slider is the same.
本發明的第三實施方式的拉鏈中，如圖5的（A）所示，於第一拉頭3c的左右相向的一對凸緣35於嚙合開始路362中分別包括凸部352且左右對稱地包括凸部352，該方面與第一實施方式的拉鏈中的第一拉頭3b不同。順便一提，於第三實施方式中，於在第一拉頭3c的上側中左右相向的一對凸緣35及在下側中左右相向的一對凸緣35，於前後方向及左右方向上於相同位置形成有相同大小的凸部352。即，第一拉頭3c為上下對稱。In the slide fastener of the third embodiment of the present invention, as shown in FIG. 5 (A), the pair of flanges 35 facing each other on the left and right sides of the first slider 3c respectively include convex parts 352 in the engagement start path 362 and include the convex parts 352 symmetrically on the left and right sides, which is different from the first slider 3b in the slide fastener of the first embodiment. By the way, in the third embodiment, the pair of flanges 35 facing each other on the left and right sides of the upper side of the first slider 3c and the pair of flanges 35 facing each other on the left and right sides of the lower side are formed with convex parts 352 of the same size at the same position in the front-rear direction and the left-right direction. That is, the first slider 3c is vertically symmetrical.
第三實施方式的拉鏈中，第一拉頭3c的所有凸緣35分別包括凸部352，因此與左側的鏈牙列5L及右側的鏈牙列5L無關，與無凸部352的拉頭相比，鏈牙5彼此容易嚙合。而且，由於在第一拉頭3c的左右相向的凸緣35左右對稱地包括凸部352，因此施加至第一拉頭3c的滑動阻力左右均等，可無不協調感地進行第一拉頭3c的移動。另外，由於第一拉頭3c於其上側及下側中，於前後方向及左右方向上於相同位置包括相同大小的凸部352，因此第一拉頭3c於其上側及下側中同樣地與鏈牙5碰撞，可無不協調感地進行第一拉頭3c的移動。In the zipper of the third embodiment, all the flanges 35 of the first slider 3c include the convex parts 352, respectively, so that the chain elements 5 are more easily engaged with each other than the slider without the convex parts 352, regardless of the chain element row 5L on the left side and the chain element row 5L on the right side. Moreover, since the convex parts 352 are included in the flanges 35 facing each other on the left and right sides of the first slider 3c in a symmetrical manner on the left and right sides, the sliding resistance applied to the first slider 3c is equal on the left and right sides, and the first slider 3c can be moved without a sense of disharmony. In addition, since the first slider 3c includes the convex parts 352 of the same size at the same position in the front-rear direction and the left-right direction on the upper side and the lower side thereof, the first slider 3c collides with the chain elements 5 on the upper side and the lower side thereof in the same manner, and the first slider 3c can be moved without a sense of disharmony.
本發明的第四實施方式的拉鏈中，如圖5的（B）所示，於第一拉頭3d的左右相向的一對凸緣35於嚙合開始路362中分別包括凹部353且左右對稱地包括凹部353，該方面與第一實施方式的拉鏈中的第一拉頭3b不同。順便一提，於第四實施方式中，第一拉頭3d設為上下對稱。In the zipper of the fourth embodiment of the present invention, as shown in FIG5 (B), the pair of flanges 35 of the first slider 3d facing each other on the left and right sides respectively include recesses 353 in the engagement start path 362 and include the recesses 353 symmetrically on the left and right sides, which is different from the first slider 3b in the zipper of the first embodiment. By the way, in the fourth embodiment, the first slider 3d is set to be symmetrical in the upper and lower sides.
第四實施方式的拉鏈中，由於第一拉頭3d的所有凸緣35分別包括凹部353，因此與左側的鏈牙列5L及右側的鏈牙列5L無關，與無凹部353的拉頭相比，鏈牙5彼此容易嚙合。而且，由於在第一拉頭3d左右相向的凸緣35左右對稱地包括凹部353，因此施加至第一拉頭3d的滑動阻力左右均等，可無不協調感地進行第一拉頭3d的移動。另外，由於第一拉頭3d上下對稱，於其上側及下側中，於前後方向及左右方向上於相同位置包括相同大小的凹部353，因此第一拉頭3d於其上側及下側中同樣地與鏈牙5碰撞，可無不協調感地進行第一拉頭3d的移動。In the zipper of the fourth embodiment, since all the flanges 35 of the first slider 3d include the recessed portion 353, the chain elements 5 are more likely to engage with each other regardless of the left chain element row 5L and the right chain element row 5L, compared with a slider without the recessed portion 353. In addition, since the flanges 35 facing each other on the left and right sides of the first slider 3d include the recessed portion 353 symmetrically, the sliding resistance applied to the first slider 3d is equal on the left and right sides, and the first slider 3d can be moved without any sense of disharmony. In addition, since the first slider 3d is symmetrical in the vertical direction, it includes recesses 353 of the same size at the same position in the front-rear direction and the left-right direction on its upper and lower sides. Therefore, the first slider 3d collides with the chain teeth 5 in the same way on its upper and lower sides, and the first slider 3d can be moved without any sense of disharmony.
本發明的第五實施方式的拉鏈中，如圖5的（C）所示，於第一拉頭3e的左右相向的一對凸緣35於嚙合開始路362中分別包括凸部352及凹部353，將凸部352及凹部353依次於嚙合方向C1上鄰接的狀態下配置，且左右對稱地包括凸部352及凹部353，該方面與第一實施方式的拉鏈中的第一拉頭3b不同。順便一提，於第五實施方式中，第一拉頭3e亦設為上下對稱。另外，關於第一拉頭3e，使左右相向的一對凸緣35的其中一者中的凸部352與另一者中的凹部353的位置關係與第一實施方式中的第一拉頭3b相同，成為於一對鏈牙列5L的鏈牙5嚙合時嚙合的兩個鏈牙5的固定部51同時位於凸部352與凹部353的關係。In the zipper of the fifth embodiment of the present invention, as shown in FIG. 5 (C), a pair of convex edges 35 of the first slider 3e facing each other on the left and right sides respectively include a convex portion 352 and a concave portion 353 in the engagement start path 362, and the convex portion 352 and the concave portion 353 are sequentially arranged in a state of being adjacent to each other in the engagement direction C1, and the convex portion 352 and the concave portion 353 are symmetrically included on the left and right sides, which is different from the first slider 3b in the zipper of the first embodiment. By the way, in the fifth embodiment, the first slider 3e is also set to be symmetrical in the upper and lower sides. In addition, regarding the first slider 3e, the positional relationship between the convex portion 352 in one of a pair of left and right facing flanges 35 and the concave portion 353 in the other is the same as that of the first slider 3b in the first embodiment, so that when the chain teeth 5 of a pair of chain tooth rows 5L are engaged, the fixing portions 51 of the two engaged chain teeth 5 are simultaneously located at the convex portion 352 and the concave portion 353.
關於第五實施方式的拉鏈，將第一拉頭3e的凸部352與凹部353的位置關係設為嚙合的兩個鏈牙5的固定部51同時位於凸部352與凹部353的關係，而且使第一拉頭3e左右對稱且上下對稱，因此可無不協調感地進行第一拉頭3e的移動。Regarding the zipper of the fifth embodiment, the positional relationship between the convex portion 352 and the concave portion 353 of the first slider 3e is set so that the fixing portion 51 of the two engaged chain teeth 5 is simultaneously located at the convex portion 352 and the concave portion 353, and the first slider 3e is made symmetrical left-right and top-bottom, so that the first slider 3e can be moved without any sense of disharmony.
本發明並不限定於所述實施方式，能夠於不脫離其主旨的範圍內適宜變更。 例如，第二拉頭3a於所述實施方式中是無凹部353及凸部352的結構，但本發明中並不限於此，只要是與第一拉頭3b不同的結構，則亦可包括凹部353或凸部352。 另外，於所述實施方式中，拉鏈包括兩個拉頭3，但本發明中並不限於此，亦可為一個或三個以上。於拉鏈包括一個拉頭3的情況下，所述拉頭3是正開拉頭，且是第一拉頭。於拉鏈包括兩個（一對）拉頭3的情況下，一對拉頭3中兩個均為第一拉頭，亦可一個為作為逆開拉頭的第一拉頭，另一個為作為正開拉頭的第二拉頭。於拉鏈包括三個以上的拉頭3的情況下，全部的拉頭中的至少一個只要為第一拉頭即可。 The present invention is not limited to the above-mentioned embodiments and can be appropriately modified within the scope of the main purpose. For example, the second slider 3a has a structure without a recess 353 and a protrusion 352 in the above-mentioned embodiments, but the present invention is not limited to this. As long as it is a structure different from the first slider 3b, it may also include a recess 353 or a protrusion 352. In addition, in the above-mentioned embodiments, the zipper includes two sliders 3, but the present invention is not limited to this and may also be one or more than three. In the case where the zipper includes one slider 3, the slider 3 is a positive opening slider and is the first slider. When the zipper includes two (a pair of) sliders 3, both of the pair of sliders 3 are first sliders, or one of them is the first slider as a reverse-opening slider, and the other is the second slider as a forward-opening slider. When the zipper includes three or more sliders 3, at least one of all the sliders only needs to be the first slider.
