201143664 六、發明說明： 【發明所屬之技術領域】 本發明係、關於-種當封閉拉鍵時，作為其開閉具之滑件 之主體不會暴露於外部之類型的隱藏式拉鏈用之滑件。 且，係關於一種在隱藏式拉鍵封閉時有較強之橫拉力作用 於滑件’仍可進行順利之滑件操作之隱藏式拉鍵用之滑 件。 【先前技術】 此種隱藏式拉鏈被較多地使用於女性用之被服類，而近 年來亦使用於被服類以外之其他領域。例如，正逐漸使用 於汽車或火車之座椅等。 座椅係被覆於預先相對框架一體形成之靠墊體上。此 時，作為椅套的尺寸，係小於靠墊體之外形尺寸而構成， 且以壓縮狀態被覆靠墊體，極力抑制外觀形狀產生之鬆弛 或變形等之發生的方式，構成座椅。 又，就座時為均勻地分散接受來自乘客的載荷，靠墊體 會在乘客就座時進行彈性變形，但椅套亦會隨著靠墊體之 彈性變形而變形。且，當乘客離開座椅時靠塾體會恢復原 形，相對於此，椅套亦會確實地恢復原形。藉由可使椅套 相對靠墊體之變形進行追從之構成’而防止座椅之變形。 椅套通常是由天然皮革或合成皮革'或積層一體化之板 構成。積層一體化之板係藉由層壓加工等將表皮層、薄彈 性中間層、及背面基布層積層一體化而構成❶表皮層係使 用具有各種結構之編織物等，薄彈性中間層係使用聚氨酯 151515.doc 201143664 發泡體板等。且，使用極細之線條編成或織成而獲得之薄 的編織物等，係作為背面基布層使用。 通常，由該等板製作座椅之椅套時，係組合根據形狀而 裁斷包含複數片板片，將其縫製成立體形狀。然而，藉由 縫製而製作椅套之整體時，會多發無法將椅套被覆於具有 複雜之外觀形狀之座椅的靠墊體的情形。因此，先前係預 先在椅套设未縫製部分，於椅套被覆於靠墊體後，再藉由 手工縫製而縫製上述未縫製部分。 在藉由手工縫製來元成最後之收尾作業的情形下，因縫 製作業人員之技能之差異’纟易在完成品之品質或直至收 尾完成品之縫製時間上產生差異。因此，近年來，為了排 除手工縫製之收尾作業，於椅套之縫製部之一部分，例如 沿著凸緣部使用拉鏈之情形逐漸增多。 又，作為使用於座椅之拉鏈，為提高外觀上之設計性， 逐漸較多地使用滑件主體不會暴露於外側之隱藏式拉鏈。 使用拉鏈之結果，可利用縫紉機進行全部之縫製作業，可 大幅改善因技能之差異而引起之先前之問題，使生產率也 提南一級。 將隱藏式拉鍵使用於如上述之汽車等之座肖冑，由於椅 套之尺寸比靠墊體之外形尺寸小，因此會對滑件附近之鍵 帶作用較強的橫拉力。其結果，係將鏈布之相對之側緣部 彎曲固uu字狀’在使用沿著侧緣部之彎曲端緣安裝有 鍵齒之鏈帶之情形下’當相對鍵帶而作用有較強橫拉力 時，鏈齒將會因該較強橫拉力而成為立起之狀態。即，鍵 151515.doc 201143664 齒會呈以嚙合頭部為上而相對鏈布之鏈布面以直角立起之 姿勢。 且，於滑件之導入口附近一面受到較強橫拉力一面被導 入於導入口之各鏈齒’係從呈相對鏈布之鏈布面以大致直 角起立之狀態的導入口被導入於滑件内。 右將各鍵齒中位於喷合頭部相反之側之鏈齒後端部搭載 於滑件之下翼板之上面’則可稍微向成水平狀態之方向傾 倒。但由於該傾倒較少’因此往往是將鏈齒從立起狀態之 導入口導入於滑件内。其結果，導致鍵齒被夾入引導鍵布 之鏈布引導路，使滑件不能滑動。 若在該狀態下勉強滑動滑件，則會導致作用有橫拉力之 鏈齒破損。且，最壞之情形，有可能使鏈布之彎曲緣斷 裂。又，以鏈齒不完全成水平狀態之狀態，將鏈齒導入於 滑件内之情形下，當封閉拉鏈時，鍵齒彼此將不能正確地 嚙合’導致產生所謂的破壞狀態。 作為可用於有如此之較強橫拉力作用之隱藏式拉鏈之滑 件’本申請案申請人已提案出一種隱藏式拉鏈用之滑件 (參照專利文獻1、2)專。該隱藏式拉鍵具備一對鍵帶，其 係將鏈布之相對之側緣部彎曲固定成U字狀，且沿著上述 側緣部之彎曲端緣安裝固定鏈齒。 將專利文獻1所記載之隱藏式拉鏈用之滑件作為本申請 發明之先前例1，於圖9顯示該滑件之立體圖。如圖9所 示，滑件41之下翼板42之左右兩側緣立設有沿著各側緣具 有逆L字剖面之左右一對第i凸緣43、料。下翼板42之前端 151515.doc 201143664 緣之中央部立設有具有大致橢圓形之水平剖面之引導柱 45 ° 形成於一對第1凸緣43、44之上板部分43a、44a間的楔 狀空間中，設置有具有於引導柱45之上面一體形成之矩形 區域46a與楔狀區域46b，且沿著引導柱45之外周向外側凸 出之第2凸緣46。且，係令第2凸緣46之距離導入口側端部 之下翼板42之下面高度，大於距離其他區域之下翼板42之 下面面度’第2凸緣46之外周面形成有錐角向喷合口侧階 段性漸增之錐面46c。 專利文獻1之發明中’作為相對下翼板42之高度，係令 第2凸緣46之導入口側之錐面46c之上端棱線部的高度，高 於嚙合口之錐面46c之上端棱線部的高度。藉由該構成， 即使以鏈齒從立起之狀態稍微向水平方向傾倒之狀態，將 其從導入口導入滑件41内，鏈齒仍不會干涉第2凸緣46， 而是被引導於第2凸緣46之錐面46c而導入至鏈齒引導通路 49 〇 在將鏈齒導入於鏈齒引導通路49期間，受到利用第2凸 緣46之錐面46c之引導、與先前利用鏈齒及鏈布之拖拉力 使鏈齒傾倒之力的综合影響，鏈齒連結部會逐漸傾向於隱 藏於第2凸緣46之下面之姿勢。且，藉由暫時利用一對第1 凸緣43、44之上板部分43 a、44a與第2凸緣46確保導入於 鍵齒引導通路49内之鏈齒的傾倒姿勢，可使其順利地進入 滑件41之鏈齒引導通路49内。 且，鏈齒不再夾著於下翼板42之上板部分43 a、44a與第 151515.doc 201143664 2凸緣46之間，因而可防止鏈齒破損或鏈布斷裂等之發 生。且，可實現滑件41之順利之滑動操作，無障礙地封閉 隱藏式拉鍵用之滑件1 ° 將專利文獻2所記载之隱藏式拉鏈用之滑件作為本申靖 發明之先前例2，於圖1〇顯示該滑件之立體圖。如圖⑺所 示，從下翼板52立設有沿著正交於滑件51之滑動方向之左 右側緣部而設置之包含逆L字形剖面之一對凸緣53、54。 下翼板52之前端緣之中央部，朝向一對上板部分53a、 Wa之間立設有引導柱55。引導柱55之外周設有朝向上板 部分53a、54a之内側端面56於外側突出之鏈齒引導部57， 上板部分53a、54a之鏈齒59之嚙合方向的前端，係延伸至 比鏈齒引導部57之前端更前方。 專利文獻2之發明中’上板部分53a、54a之鍵齒59之喷 合方向的前端係延伸至比鏈齒引導部57之前端更前方。藉 由該構成，在鏈齒59分離至比滑件51更靠嚙合方向之前方 的位置’即使呈以嚙合頭部59a為上，相對鍵布6〇以直角 立起之姿勢，仍可一面使鏈齒59接觸於延伸設置於鏈齒引 導部57之前端之前方的上板部分53a、54a，一面將其引導 至滑件5 1内。 且’ 一面接觸於上板部分53a、54a—面引導至滑件51内 之鍵齒59 ’會受到來自以水平狀態之姿勢傾倒之先前鏈齒 59的作用’而被作用有以水平狀態傾倒之傾倒力。又，基 於滑件5 1之滑動操作，鏈齒59上作用有將鏈布60拖拉入滑 件5 1内之拖拉力。 151515.doc 201143664 藉此，左右一對鏈齒59直至在進入滑件51之鏈齒引導通 路期間，係由以直角立起之姿勢傾倒為水平狀態。且，键 布60係-面滑接於上板部分53a、Ma_面接近引導柱^， 因此可使鏈齒59之嚙合頭部59a接觸於鏈齒引導部57。 且，向水平狀態適度傾倒之姿勢之各鏈齒59，係一面使 . 其嚙合頭部59a接觸於鏈齒引導部57—面導入至滑件51之 鏈齒引導通路58内。鏈齒59之嚙合頭部59&可一面逐漸向 隱藏於鏈齒引導部57之下方之姿勢傾倒，一面於鏈齒引導 通路5 8内向喷合口側順利地移動。 藉此，可以完全地以水平狀態傾倒之正確姿勢（嚙合姿 勢）使左右一對鏈齒59嚙合。且，鏈齒59不會再如先前般 齧入凸緣53、54與鍵齒引導部57之間所形成之鍵布引導通 路，因此可防止鏈齒59之破損或鏈布6〇之斷裂等發生。如 此，專利文獻2之發明可進行滑件51之順利之滑動操作， 可無障礙地封閉隱藏式拉鏈。 先前技術文獻 專利文獻 專利文獻1:日本特開2007-54176號公報 專利文獻2:曰本特開2007-135722號公報 【發明内容】 發明所欲解決之問題 專利文獻i、2之發明作為基本之構成，係對於相對鍵布 以直角立起之姿勢的鏈齒，引導鏈齒之喷合頭部，藉此可 使鏈齒傾動成水平狀態之姿勢。 151515.doc 201143664 因此，專利文獻1、2之發明中，當使以直角立起之姿勢 的鏈齒傾動成水平狀態之姿勢時，作為滑接於鏈齒之嚙合 頭部而賦與轉矩之引導部，專利文獻丨之發明係設置沿著 引導柱45之外周向外側凸出之第2凸緣46，專利文獻2之發 明係設置鏈齒引導部57。 藉由以專利文獻1、2之發明而構成，可使以直角立起之 姿勢之鍵齒傾動為成為唾合姿勢之水平狀態之姿勢。 然而，利用作用於鏈布之橫拉力而傾倒之鏈齒，會因橫 拉力施加之方向、橫拉力之大小的不同，而導致以各種角 度傾倒。因此，相對可賦與轉矩之引導部抵接鏈齒之角度 會不安定。 又，當對鏈佈施加更強之橫拉力時，會導致鏈齒不能積 極地抵接於引導部而是沿著鏈布之長度方向滑動，亦有鏈 齒不能平滑地恢復至水平位置之情形，因此，尚有改善之 餘地* 尤其在沿著鏈布之端緣用縫線縫製而安裝固定鏈齒的情 形下，鏈齒不會成為相對鏈布一體固定之狀態。因此，亦 會產生作用有較強之橫拉力之鏈布一面對於鏈齒產生相對 移動一面朝橫拉方向移動之情形。 在相對鏈布向橫拉方向之移動量，鏈齒之移動量較少之 隋也下例如，專利文獻1之發明無法令键齒之頭部接觸 或以較強之力賦能於第2凸緣46之錐面4以。又，專利文獻 2之發明無法令鏈齒59之嚙合頭部59&接觸或以較強之力賦 能於鏈齒引導部57。 151515.doc 201143664 若為如此之狀態，則無法令用以相對傾倒姿勢之鏈齒而 使立起之姿勢傾倒為水平狀態的轉矩從第2凸緣Μ之錐 面46c或鏈齒引導部57作用於鏈齒。 本申請發明之發明者在實施各種研討之結果認識到，當 於相备於專利文獻1之錐面46c或專利文獻2之鏈齒引導部 57之第1鏈齒引導部抵接或抵接前，使鏈齒之鏈齒後端部 滑接於第2鏈齒引導部，藉此可以作為嚙合姿勢之水平狀 態之姿勢使鏈齒傾動，從而完成本申請發明。 且，藉由如本中請發明般地構成隱藏式拉鏈用之滑件， 可使從第2鏈齒引導部相對鏈齒作用之力、及從傾倒為水 平狀態之姿勢之先前鍵齒使鏈齒以水平狀態之姿勢傾倒之 扭力、將鏈布拖拉入滑件内之拖拉力等，有效地作用於導 入至滑件内之鏈齒。 藉由使該等力作用於鏈齒，使成為相對鏈布以大致直角 立起之姿勢的鏈齒向成為唾合姿勢之水平狀態之姿勢傾 動。且，鏈帶可一面逐漸傾倒，一面於形成於滑件内之γ 字狀的鏈齒引導通路内向嚙合口側順利地移動。藉此，鍵 齒可在形成於滑件内之Υ字狀的鏈齒引導通路内順利地移 動。 且’可避免鏈齒夾於Υ字狀之鏈齒引導通路間之事態， 因此可順利地進行滑件之滑動操作。 如此，本申請發明之目的在於提高一種對專利文獻1、2 之發明加以進一步改良，藉此即使於拉鏈封閉時施加較強 橫拉力，仍可進行順利之滑件之滑動操作的隱藏式拉鏈用 15I515.doc • 11 · 201143664 之滑件。 解決問題之技術手段

Description of the Invention: [Technical Field] The present invention relates to a slide for a hidden zipper of a type in which the main body of the slider of the opening and closing device is not exposed to the outside when the button is closed. . Further, it relates to a slider for a concealed pull button which has a strong lateral pulling force when the concealed pull button is closed and which acts on the slider 'can still perform a smooth slider operation. [Prior Art] Such concealed zippers are used more in women's clothing, and have been used in other fields than in the past. For example, it is gradually being used in seats for cars or trains. The seat is covered on a cushion body that is integrally formed with respect to the frame in advance. In this case, the size of the seat cover is configured to be smaller than the outer dimensions of the cushion body, and the cushion body is covered in a compressed state, and the occurrence of slack or deformation of the outer shape is suppressed as much as possible to constitute the seat. Further, when seated, the load from the passenger is uniformly dispersed, and the cushion body is elastically deformed when the passenger is seated, but the seat cover is also deformed in accordance with the elastic deformation of the cushion body. Moreover, when the passenger leaves the seat, the body will return to its original shape, and the seat cover will surely return to its original shape. The deformation of the seat is prevented by making the seat cover conform to the deformation of the cushion body. The seat cover is usually made of natural leather or synthetic leather' or a laminated board. The laminated layer is formed by laminating a skin layer, a thin elastic intermediate layer, and a back base fabric layer by lamination processing, etc., and forming a ruthenium skin layer using a woven fabric having various structures, and a thin elastic intermediate layer is used. Polyurethane 151515. Doc 201143664 Foam board, etc. Further, a thin knitted fabric obtained by knitting or weaving with extremely fine lines is used as a back base fabric layer. Usually, when the seat cover of the seat is made of the boards, the combination includes cutting a plurality of sheets according to the shape and sewing them into a three-dimensional shape. However, when the entire seat cover is made by sewing, there are many cases where the seat cover cannot be covered by the seat body of the seat having a complicated appearance. Therefore, in the prior art, the unsewed portion was previously set in the seat cover, and after the seat cover was covered on the cushion body, the unsewed portion was sewn by hand sewing. In the case of the final finishing work by hand sewing, the difference in the skill of the sewing worker is likely to vary in the quality of the finished product or the sewing time of the finished product. Therefore, in recent years, in order to eliminate the finishing work of hand sewing, a part of the sewing portion of the seat cover, for example, a zipper is used along the flange portion. Further, as a zipper for a seat, in order to improve the design of the appearance, a hidden zipper in which the slider body is not exposed to the outside is gradually used. As a result of the zipper, the sewing machine can be used to perform all the sewing operations, which can greatly improve the previous problems caused by the difference in skills and increase the productivity to the next level. The concealed pull key is used in the seat of the automobile as described above, and since the size of the seat cover is smaller than the outer shape of the cushion body, a strong lateral pulling force is exerted on the key band near the sliding member. As a result, the opposite side edges of the chain cloth are bent and uu-shaped. In the case where the fastener tape is attached with the key teeth along the curved end edge of the side edge portion, it acts strongly against the key band. When pulling, the chain teeth will become in a standing state due to the strong lateral pulling force. That is, the key 151515. Doc 201143664 The teeth will assume that the meshing head is up and the chain cloth surface of the chain is raised at right angles. In addition, each of the fastener elements that are introduced into the introduction port in the vicinity of the introduction port of the slider is introduced into the slider from the inlet port that is raised at a substantially right angle to the chain fabric surface of the chain fabric. . Right, the rear end portion of the sprocket on the opposite side of the splicing head of each of the key teeth is mounted on the upper surface of the lower blade of the slider, so that it can be slightly tilted in the direction of the horizontal state. However, since the dumping is less, it is often the case that the sprocket is introduced into the slider from the erecting inlet. As a result, the key teeth are caught in the chain guide path of the guide key cloth, so that the slider cannot slide. If the slider is barely slid in this state, the sprocket which is subjected to the transverse pulling force is broken. And, in the worst case, it is possible to break the curved edge of the chain cloth. Further, in the case where the fastener element is introduced into the slider in a state where the fastener element is not completely horizontal, when the zipper is closed, the key teeth cannot be properly engaged with each other, resulting in a so-called destruction state. As a slider which can be used for a concealed zipper having such a strong lateral pulling force, the applicant of the present application has proposed a slider for a concealed zipper (refer to Patent Documents 1 and 2). The concealed pull key includes a pair of key bands which are bent and fixed in a U shape to the opposite side edges of the chain cloth, and the fixed fastener elements are attached along the curved end edges of the side edge portions. A slider for a concealed slide fastener described in Patent Document 1 is referred to as a prior art 1 of the present invention, and a perspective view of the slider is shown in Fig. 9 . As shown in Fig. 9, the right and left side edges of the lower wing 42 of the slider 41 are provided with a pair of right and left ith flanges 43 having the reverse L-shaped cross section along the respective side edges. The front end of the lower wing 42 is 151515. Doc 201143664 A guide post 45° having a substantially elliptical horizontal section is formed in a central portion of the edge, and is formed in a wedge-shaped space between the upper plate portions 43a and 44a of the pair of first flanges 43 and 44, and is provided with The rectangular portion 46a and the wedge-shaped region 46b integrally formed on the upper surface of the guide post 45 and the second flange 46 projecting outward in the outer circumferential direction of the guide post 45. Further, the height of the lower surface of the lower flange 46 of the second flange 46 from the inlet side end portion is greater than the lower surface of the lower flange 42 of the other region. The outer peripheral surface of the second flange 46 is tapered. The tapered surface 46c is gradually increased toward the side of the spray port. In the invention of Patent Document 1, the height of the upper ridge line portion of the tapered surface 46c of the inlet port side of the second flange 46 is higher than the height of the lower blade 42, and is higher than the upper edge of the tapered surface 46c of the engaging opening. The height of the line.

Moreover, the sliding operation of the sliding member 41 can be smoothly performed, and the sliding member for the hidden type of the sliding member can be closed without any trouble. The sliding member for the hidden zipper described in Patent Document 2 is used as the previous example of the present invention. 2, a perspective view of the slider is shown in FIG. As shown in Fig. 7 (7), the pair of flanges 53, 54 are provided from the lower blade 52 so as to be provided along the left and right edge portions orthogonal to the sliding direction of the slider 51, and including the reverse L-shaped cross section. A guide post 55 is disposed between the pair of upper plate portions 53a and Wa at a central portion of the front edge of the lower blade 52. The outer circumference of the guide post 55 is provided with a sprocket guide portion 57 projecting outward toward the inner end surface 56 of the upper plate portions 53a, 54a, and the front end of the sprocket 59 of the upper plate portions 53a, 54a is extended to the specific sprocket The front end of the guide portion 57 is further forward. In the invention of Patent Document 2, the front end of the joining direction of the key teeth 59 of the upper plate portions 53a and 54a extends further forward than the front end of the element guide portion 57. With this configuration, the position "before the sprocket 59 is separated into the direction in which the slider 51 is engaged with the slider 51" can be made even if the engaging head portion 59a is up and the button cloth 6 erects at a right angle. The sprocket 59 is in contact with the upper plate portions 53a, 54a extending forward of the front end of the sprocket guiding portion 57, and is guided into the slider 51. And the key teeth 59' that are in contact with the upper plate portions 53a, 54a to be guided into the slider 51 are subjected to the action of the previous sprocket 59 from the posture in the horizontal state, and are caused to fall in a horizontal state. Dumping force. Further, based on the sliding operation of the slider 51, the sprocket 59 exerts a pulling force for pulling the chain cloth 60 into the slider 51. 151515.

Further, the key cloth 60 is slidably attached to the upper plate portion 53a and the Ma_ surface is close to the guide post, so that the engaging head portion 59a of the sprocket 59 can be brought into contact with the sprocket guiding portion 57. Further, each of the fastener elements 59 in the posture in which the horizontal state is appropriately tilted is one side. The engaging head portion 59a is in contact with the sprocket guiding portion 57 to be introduced into the sprocket guiding passage 58 of the slider 51. The engaging head portion 59& of the sprocket 59 is gradually tilted toward the lower side of the sprocket guiding portion 57, and smoothly moves toward the splicing port side in the sprocket guiding passage 58. Thereby, the pair of left and right sprocket teeth 59 can be meshed in the correct posture (engaging posture) in which the horizontal state is completely collapsed. Further, the sprocket 59 does not engage the key guide path formed between the flanges 53, 54 and the key guide portion 57 as before, thereby preventing breakage of the fastener elements 59 or breakage of the link cloth 6 等, etc. occur. Thus, the invention of Patent Document 2 can perform a smooth sliding operation of the slider 51, and can block the hidden zipper without any trouble. CITATION LIST Patent Literature Patent Literature 1: JP-A-2007-54176 (Patent Document 2) JP-A-2007-135722 DISCLOSURE OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION Problems of Patent Documents i and 2 as Basic In the configuration, the sprocket in a posture in which the key is raised at a right angle is guided to the lance head, whereby the sprocket can be tilted into a horizontal posture. 151515. Doc 201143664 Therefore, in the inventions of Patent Documents 1 and 2, when the fastener element in the posture of standing at a right angle is tilted to a horizontal state, the guide portion for imparting torque to the meshing head of the element is attached. In the invention of the patent document, the second flange 46 that protrudes outward in the outer circumferential direction of the guide post 45 is provided, and the invention of Patent Document 2 provides the sprocket guide portion 57. According to the inventions of Patent Documents 1 and 2, the key teeth of the posture in which the posture is raised at a right angle can be tilted into a posture in a horizontal state of the saliva posture. However, the sprocket which is poured by the transverse pulling force acting on the chain cloth may be dumped at various angles due to the difference in the direction in which the transverse pulling force is applied and the magnitude of the transverse pulling force. Therefore, the angle at which the guide portion that can be biased with the torque abuts against the sprocket is unstable. Moreover, when a stronger transverse pulling force is applied to the chain cloth, the chain teeth cannot be positively abutted against the guiding portion but slide along the length of the chain cloth, and the chain teeth cannot be smoothly restored to the horizontal position. Therefore, there is still room for improvement. In particular, in the case where the fastener element is attached by stitching along the edge of the chain cloth, the fastener element does not become a state in which the fastener element is integrally fixed. Therefore, there is also a case where the chain cloth which has a strong transverse pulling force moves in the horizontal pulling direction with respect to the relative movement of the fastener elements. In the case where the amount of movement of the fastener element in the transverse direction is small, the amount of movement of the fastener element is small. For example, the invention of Patent Document 1 cannot make the head of the key tooth contact or energize the second protrusion with a strong force. The tapered surface 4 of the rim 46 is. Further, the invention of Patent Document 2 cannot cause the engaging heads 59& of the fastener elements 59 to contact or energize the sprocket guiding portion 57 with a strong force. 151515.

Chain teeth. As a result of carrying out various studies, the inventors of the present invention have recognized that before the first sprocket guide portion of the sprocket guide portion 57 of the patent document 1 or the sprocket guide portion 57 of the patent document 2 abuts or abuts The sprocket rear end portion of the fastener element is slidably attached to the second sprocket guide portion, whereby the sprocket can be tilted as a posture in a horizontal state of the meshing posture, thereby completing the invention of the present application. Further, by forming the slide for the hidden slide fastener as in the present invention, the force acting from the second sprocket guide portion against the sprocket and the previous key at the posture of tilting from the horizontal state can be used to make the chain The torque that the teeth are tilted in a horizontal state, the pulling force that drags the chain cloth into the slider, and the like, effectively acts on the fastener elements introduced into the slider. By applying these forces to the sprocket, the sprocket which is in a posture in which the chain is raised at a substantially right angle is tilted in a posture in a horizontal state in a salivating posture. Further, the chain belt can be gradually tilted while being smoothly moved toward the engagement opening side in the γ-shaped sprocket guide passage formed in the slider. Thereby, the key teeth can be smoothly moved in the U-shaped sprocket guiding passage formed in the slider. Moreover, the situation in which the fastener element is sandwiched between the sprocket-shaped sprocket guiding passages can be avoided, so that the sliding operation of the slider can be smoothly performed. As described above, the object of the present invention is to improve the invention of Patent Documents 1 and 2, whereby the 15I515 can be used for a hidden zipper that can smoothly slide the slider even when a strong lateral pulling force is applied when the zipper is closed. .

Slide for the pull button. Here, the front end portion of the pair of upper plates that are slidably attached to the bent portion of the chain cloth introduced into the slider will be described as a clearing of the pivot point at which the chain cloth is bent by the lateral pulling force. At this time, the distance from the above-mentioned pivot point to the engaging head is longer than the distance from the rear end of the element of the rotating fulcrum. Therefore, as the torque for tilting the sprocket, the torque element can be given a larger torque force to the sprocket rear end than the sliding guide engagement head portion. In this way, even if the sprocket which is introduced before the slider is directly introduced in a posture which is raised at a substantially right angle with respect to the chain, the sprocket rear end on the opposite side of the squeezing head is guided as a portion of the sprocket which is initially guided. In this way, the torque for the posture in which the relative sprocket is in a horizontal state can be effectively imparted. In addition, when the fixed fastener element is attached by sewing the stitch along the edge of the key cloth, since the fastener element is not integrally fixed to the chain cloth, even if the chain cloth is moved by the lateral pulling force, the key tooth does not move relative to the key cloth. And one moves, but becomes 151515. Doc 201143664 The state of the residual ^, relative to the movement direction of the chain guide path along the chain cloth, the sprocket moves in this direction. Therefore, in the movement of the chain guide passage along the chain cloth, the rear end portion of the element of the fastener element is slid while being moved to the second key guide portion. Further, the head portion of the key teeth is moved by the (4) 1 key tooth guiding portion side according to the second key tooth guiding portion, so that the engaging head portion can be slidably attached to the second sprocket guiding portion. In this manner, the stalk rear end portion is guided while being in contact with the second sprocket guide portion and is slidably coupled to the first sprocket guide portion. Further, the second element guide portion can be used to gradually bring the element in the standing state into a horizontal state. Further, by sliding the meshing head of the element supported by the second element guide portion to the first element guide portion, it is possible to reliably tilt the posture in the horizontal state.

As shown in Fig. 5, the pair of key teeth 13 are disposed such that the mutually engaging head portions 13a face each other, and the opposite sides of the engaging head portions 13a are coupled by the inverting portions. Fig. 5 is a cross-sectional view of the slider 1 in which the upper plates 3b and 4b and the first element guide portion 7 are omitted, and shows the element 13 introduced into the element guide passage 1 of the lower blade 2. 6 is a view showing that the second sprocket guide 8 is slidably coupled to the stalk rear end portion 13b' and the meshing head portion 13a is slidably coupled to the first sprocket guide portion 7, whereby the sprocket introduced into the slider 1 is introduced. 13 is a state in which the posture of the fastener element 13 introduced into the element guide passage 10 changes in a state of standing up. Figure 7 is a cross-sectional view taken along line A-A of Figure 5, and Figure 8 is a cross-sectional view taken along line b_b of Figure 5. As can be understood from Fig. 5, the pair of chain belts 15 on the side of the introduction port 6 of the slider 处于 are in a state of being greatly opened by a strong lateral pulling force with a pair of upper flaps and a front end edge 21 as a pivot point. . At this time, the sprocket 3 raises the engaging head portion 13a upward at a position close to a right angle with respect to the chain cloth surface of the chain cloth 14. By sliding the slider 1 in the closing direction (upward direction of FIG. 5), the sprocket rear end portion 13b of the continuous sprocket 13 is sequentially slidably guided to the second sprocket guiding portion 8 of the slider 丨. The step 8 is recognized on the guide surface 8b. At this time, the key teeth 13' that are slidably attached to the second key guide portion 8 are in a posture in which the meshing head portion 13a is raised upward due to the influence of the strong lateral pulling force acting on the chain cloth. The slide member slides the Japanese temple in the closing direction, and the front chain 13 acts on the previous chain in which the sprocket 13 is tilted from the second sprocket guide 8 in the horizontal state by the torque λ k in a horizontal state.

Further, as shown in Fig. 7, the meshing head portion Ua is further slidably attached to the front surface guide surface 7a of the first sprocket guide portion 7, so that the element η is further tilted in a horizontal state. Further, as shown in FIG. 8, the fastener element U can be in a horizontal state. As shown in Fig. 6, the sprocket 13 in the upright posture is a posture in which the surface is rotated in a clockwise direction and gradually tilted to a horizontal state. Thus, in the invention of the present application, when the sprocket 13 of the standing posture is introduced into the slider, the first sprocket rear end portion 13b is biased from the second sprocket guide 8 so that the sprocket 13 is formed. In the posture of the horizontal state, the feeding head portion 13a is biased from the first sprocket guiding portion 7 in a posture for causing the fastener elements 13 to be horizontal. Further, since one of the first sprocket guiding portions 7 is formed continuously with the side guiding surface 7a as the inclined surface, the sprocket 13 which is poured into the horizontal state can be smoothly introduced into the sprocket meshing region. ′′′ as shown in FIG. 7 'sliding from the curved portion 14a of the chain cloth 14 introduced into the slider 1 to the front end of the upper plate 3b, 4b, the distance to the engaging head 13a, the chain The distance between the rear end portions 13b of the teeth is long.

With this configuration, before the first sprocket guiding portion 7 forcibly rotates the engaging head portion 13a of the sprocket 13 in the horizontal posture direction, or the front edge of the pair of upper plates 3b, 4b is used to make the chain cloth 4 relative to each other. Before the longitudinal direction is bent, the second spur guide portion 8 can impart a torque for rotating the sprocket 13 in the horizontal posture direction to the stalk rear end portion 13b. Further, the second element guide portion 8 supports the element 13 so that the torque of the i-th element guide portion 7 (the front surface guide surface 7a) is easily applied. Therefore, the chain cloth 14 can be smoothly guided into the chain guide passage 12, and when the meshing head portion 13a of the fastener element 13 is slidably coupled to the first sprocket guide portion 7, the inclination angle of the key teeth 13 can be oriented to some extent. In the horizontal posture direction side β, in particular, as shown in FIG. 7, in the case where the fixed fastener element 13 is attached by sewing the suture 27 along the end edge of the chain cloth μ, the fastener element 13 is not integrally fixed to the chain cloth 14. status. Therefore, the chain cloth 14 which is subjected to the tensile force will have a relative movement with respect to the element 13 and a direction of the lateral force. Further, even if the chain cloth 14 is relatively moved toward the sprocket 3 due to the lateral pulling force, and the sprocket 3 is left in the moving direction of the chain cloth 14, the chain guide path 12 is relatively opposed to the chain cloth 14. In the moving direction, the sprocket 13 still moves integrally with the same direction.
