以下’ 4基於圖式詳細說明本發明之拉鍵之各實施形 態。另，於其後之說明中，關於鏈布，表側係相對圖i之 紙面的手前側，裏側係相對圖1之紙面的裏側，亦可將垂 直於鏈布之面之方向稱為表裏方向。上側係相對圖1之紙 面之上侧’下側係相對圖1之紙面之下側，左側係相對圖1 之紙面之左側’右側係相對圖1之紙面之右側，關於滑 件’上側係相對圖1之紙面之手前側（後述之具有拉片之 側），下側係相對圖1之紙面之裏側，前側係相對圖1之紙 面之上側’後側係相對圖1之紙面之下側，左側係相對圖1 之紙面之左側’右側係相對圖1之紙面之右側。又，鍵布 及滑件之左右方向亦稱為寬度方向。又，上下方向亦稱為 鏈布之長度方向。上述寬度方向在鏈布之面上為水平，且 亦為正交於上述長度方向之方向。 (第1實施形態） 首先’參照圖1〜圖12，說明本發明之拉鏈之第1實施形 態。 如圖1及圖2所示’本實施形態之拉鏈10具備：左右一對 鏈布20’其於編織製成之鏈布材之表背兩面具有包含合成 樹脂製之熱可塑性彈性體（例如聚酯彈性體或聚氨酯彈性 體等）的防水層21 ;左右一對鏈齒排3〇，其係沿著左右一 151516.doc 201141412 對鏈布20之對向之鏈布側緣部2〇a而分別排設，且具有複 數個鏈齒3 1 ;上開滑件4〇a及下開滑件4〇B，其係使左右 一對鏈齒排30插通，並嚙合.分離；筒銷5〇，其係安裝於 右側（一方）之鍵布20之不存在複數個键齒31之下端部（一端 部）的表背兩面，插銷60，其係安裝於左側（另一方）之鏈布 20之不存在複數個鏈齒31之下端部（一端部）的表背兩面； 及上止擋70，其係分別安裝於左右一對鏈布2〇之不存在複 數個鏈齒31之上端部。 上述防水層21係通過防水層21而不令水通過之層，但不 限於水，亦包含液體（流體）者，例如油或氣體。另，鏈布 材除了編織製以外亦可為非編織布者。又，左右一對鏈布 20可具備上止擋70，再者，亦可不具備上止擋7〇。該情形 下，將拉鍵1 0女裝於衣服等之被著物上時，係以不使上開 滑件40A脫離之方式進行安裝。 左右一對鏈齒排30各者包含複數個鏈齒31，該鏈齒31係 使用例如聚醯胺、聚縮醛、聚丙烯、聚對苯二曱酸丁二醇 酯等之合成樹脂，於鏈布20之鏈布側緣部2〇a射出成形。 上開滑件40A及下開滑件40B係具自動停止功能之滑 件，且以使嚙合口側對向之方式配設。且，當拉動拉片41 將上開滑件40A向上方（從下開滑件4〇B離開之方向）移動 時’處於分離狀態之左右一對鏈齒排3〇將相互喃合；當向 下方（向下開滑件40B接近之方向）移動時，處於嚙合狀態 之左右一對鏈齒排30將分離。又，當拉動拉片“將下開滑 件40B向上方（向上開滑件40A接近之方向）移動時，處於嚙 151516.doc -6- ⑧ 201141412 合狀態之左右一對鏈齒排30將分離；當向下方（從上開滑 件40A離開之方向）移動時’處於分離狀態之左右一對鏈齒 排30將相互喷合。 筒銷50及插銷60如圖2〜圖7所示，係利用例如聚醯胺、 聚縮醛、聚丙烯、聚對苯二曱酸丁二醇酯等之合成樹脂， 射出成形於鏈布20之鏈布側緣部2〇a之下端部。 筒銷50為大致角柱狀之構件，其下半部係以寬度方向尺 寸隨著從鏈齒31向鏈布20之長度方向（下方向）分離而增大 的方式形成。又，筒銷5〇之與上端部之插銷6〇對向之側 面 $成有與後述之插銷60之扣合凹部62扣合，如圖8所 不’決定插銷60相對下開滑件4〇b之插入位置的止擋件 51。又，如圖8之放大部分所示，筒銷5〇之下端部之寬度 方向兩端部分別形成有與下開滑件40B之引導柱42及凸緣 43接觸’防止下開滑件40B脫離的拔止部52。 插銷60為大致角柱狀之構件，其上端部之與筒銷50對向 之側面，如圖8所示，形成有與筒銷50側之鏈齒排30之最 下知之鏈齒3 1扣合的扣合部61。又，插銷60之上述扣合部 61之下方之側面形成有與上述筒銷50之止擋件5丨扣合之扣 S凹邛62。又，如圖7及圖8所示，插銷60之大致中央部之 表面形成有扣止下開滑件40B之停止爪44之階部63。如圖7 所不’階部63之下方側比上方側之表背方向的厚度薄。 又’如圖2〜圖4所示，插銷6〇之下端部之從筒銷5〇分離之 側的側面形成有插銷固著構件64，其形成於從該側面向寬 又方向外側（從绮銷5〇離開之方向）延伸之鏈布的表背兩 151516.doc 201141412 側。又，設插銷固著構件64之厚度薄於插銷6〇。 上述實施形態中，插銷60係從上開滑件4〇a之引導柱之 左側插入之構件，筒銷50係保持上開滑件4〇a及下開滑件 40B之構件。因此，插銷6〇及筒銷5〇係被收納於上開滑件 糧及下開滑件_之内冑，表背方向之尺寸比鏈布2〇 大。因此，在將插銷60及筒銷5〇收納於滑件内部之狀態 下’將其抵接於滑件之凸緣，防止於寬度方向脫離。 此處說明上述拉鍵1 0，係以使上開滑件40A及下開滑 件40B移動至下端（筒銷5〇)之狀態，從上開滑件4〇a插入插 銷60，直至插入扣合於筒銷5〇之止擋件51後，將上開滑件 40A朝上方移動，藉此嚙合左右之鏈齒排3〇，封閉拉鏈 10。 以該狀態將下開滑件4〇b朝上方移動時，左右之鏈齒 排3 0將從请銷5 0及插銷6 〇側分離。 且，本實施形態中，如圖2〜圖7所示，筒銷5〇之表背兩 面形成有具有從表面及背面到達至鏈布2〇之深度的凹部 11、 12，插銷60之表背兩面形成有具有從表面及背面到達 至鏈布20之深度的凹部u、u。該凹部n、12係藉由在將 筒銷50及插銷60射出成形時’令圖9及圖1〇所示之模具8〇 之鏈布按塵構件81 (未圖示插銷60側之模具）按壓鏈布2〇而 形成者。因此，凹部11、12係形成於鏈布20之鏈布側緣部 20a之内側（鏈布20上）。另，圖9及圖1〇中之符號82係為射 出形成筒銷50而填充溶融樹脂之腔室，符號83係射出成形 時用於收納鏈齒3 1之键齒收納空間。鍵布按壓構件8丨係沿 著鏈布側緣部20a按壓鏈布20，因此鏈布側緣部2〇a不會於 151516.doc 201141412 表背方向上產生波狀。 又’筒銷50之鏈齒排3〇側之凹部丨丨及插銷6〇之凹部^係 沿著鍵布20之長度方向形成長圓形狀，筒銷50之下方側 (上述凹部11之下方側）之凹部12係沿著鏈布2〇之長度方 向’且以寬度方向尺寸隨著從鏈齒31向鏈布2〇之長度方向 (下方向）離開而增大的方式，形成大致梯形形狀。又，如 圖3及圖4所示’插銷固著構件64之表背兩面形成有2個梯 形形狀之凹部13、及3個圓形之凹部14。再者，如圖！所 不，上止擋部70之表背兩面沿著鏈布2〇之長度方向而形成 有長圓形狀之凹部15。 又，如圖3〜圖7所示，右側之鏈布2〇中，筒銷5〇之凹部 11之上方、凹部丨丨、12間、及凹部12之下方的位置分別形 成有固著用貫通孔22。藉此，利用經由3個固著用貫通孔 22而形成之連結部22a，將鏈布2〇之表背兩面側之筒銷％ 連結於表背方向。另，固著用貫通孔22係將鏈布2〇貫通於 表背方向。 又，左側之鏈布20中，插銷6〇之凹部11之上方、凹部 U、11間、及凹部11之下方之位置分別形成有固著用貫通 孔22。藉此，利用經由3個固著用貫通孔22而形成之連結 部22a，將鏈布20之表背兩面側之插銷6〇連結於表背方 向。又，插銷固著構件64之上側之凹部14、14間之位置， 亦形成有與上述固著用貫通孔22相同之固著用貫通孔U。 再者，左右一對之鏈布20之各鏈齒31之成形位置上分別 形成有固著用貫通孔24。藉此，利用經由固著用貫通孔Μ I515I6.doc 201141412 而形成之連結部24a ’將鏈布20之表背兩面側之鏈齒3 i連 結於表背方向。 如以上所說明，根據本實施形態之拉鏈10，由於筒銷50 及插銷60之表背兩面形成有在鏈布2〇之長度方向上較長的 凹部11、12’因此’可使射出成形時形成凹部丨丨、12且按 壓鏈布20之鏈布按壓構件81之按壓面積大於先前之銷狀之 键布按壓構件’進而可確實地固定射出成形時之鏈布2〇之 寬度方向及表背方向之位置。藉此，可使得於具有防水層 21之鏈布20上形成筒銷50及插銷60時之射出成形時的鏈布 20的位置安定’故可大幅提高筒銷50及插銷60相對鏈布2〇 之安裝強度。又’由於鏈布按壓構件81之按壓面積較大， 因此可減少樹脂之使用量，因而可削減製造成本。再者， 其凹部11、12之長度方向之尺寸比寬度方向之尺寸長，較 佳為2倍以上，更佳為3倍以上。 又，根據本實施形態之拉鏈10，由於係於鏈布20之凹部 11、12(11、11)間之位置形成固著用貫通孔22，且以確實 地按壓鏈布20之狀態，經由固著用貫通孔22於表背連結， 因此，可進一 f提高筒銷50及插銷60相對鏈布20之安裝強 度。 又，根據本實施形態之拉鏈10，由於形成於筒銷50之凹 部12，其寬度方向尺寸會隨著從鏈齒31向鏈布2〇之長度方 向分離而增大’因此可在鏈布20之下端側進一步增大鏈布 按壓構件81之按壓面積，進而可更佳確實地固定射出成形 時之鏈布20之位置。又，由於可進一步減少樹脂之使用 1515l6.doc •10· 201141412 量’因此可進一步削減製造成本β 又’為保持筒銷50及插銷60之強度，如圖8所示，較好 的是，將插銷60之凹部11定位而形成於扣合部61之下方。 藉此’可在扣合部61與筒銷50側之最下端之鏈齒31扣合的 狀態下，充分克服橫拉力。再者，插銷60之複數個凹部11 中’下方側之凹部11在將下開滑件40Β抵接於階部63之狀 態下’係位於階部63與停止爪44之抵接位置的左側。藉此 而防止下開滑件40Β之停止爪44嵌入凹部11。又，筒銷5〇 之凹部11係定位而形成於止擋件5 1與插銷60之扣合凹部62 之面的下方，因此可保持安裝強度。 又’根據本實施形態之拉鏈10，由於插銷60上形成有複 數個凹部11、11，且插銷60之表面上，於複數個凹部11、 11之間的位置形成有階部63，因此可於形成有複數個凹部 11、11之插銷60之適宜位置形成階部63。 另，作為本實施形態之變形例，如圖11及圖丨2所示，亦 可將防水層21僅設置於鏈布20之表面。 (第2實施形態） 其次’參照圖13及圖14，說明本發明之拉鍵之第2實施 形態。另’就與第1實施形態相同之等同部分，係於圖式 賦與相同符號，且省略或簡略化其說明。 本實施形態之拉鏈10，如圖13及圖14所示，取代上述第 1實施形態之包含筒銷50、插銷60、及下開滑件4〇b之逆開 具，係使用開具90。因此’雖未圖示，但本實施形態之拉 鏈10僅具備上開滑件40A。 151516.doc -11 · 201141412 開具90具備：筒銷50及開尾筒55，其形成於右側之鏈布 20之鍵布側緣部20a之下端部；及插銷60，其形成於左側 之鏈布20之鏈布側緣部20a之下端部，且可插入開尾筒 55 〇 開尾筒55係一體成形於筒鎖50之下部，且於其左半部形

Description of the Invention: [Technical Field of the Invention] The present invention relates to a zipper, and more particularly to a zipper, a tail cylinder, and a latch. [Prior Art] As a conventional zipper, it is known that a plurality of key-toothed mounting edges along the plane facing the water-repellent chain cloth having the waterproof layer covering the surface of the strip-shaped core material are arranged. The sprocket has a pair of front and back sides of a pair of chain cloths which are not at the end of the plane of the sprocket, and the pin and the pin are oppositely fixed, and have a slider inserted through the sprocket and have a slave A pin fixing member that is integrally fixed to the front and back sides of the chain cloth on the side of the chain end side of the chain (see, for example, Patent Document 1). Patent Document 1: Japanese Patent Application Publication No. 2007-97840 SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION The zipper of the above-mentioned Patent Document 1 is formed by forming a pin, a tail cylinder, and a pin in a chain fabric. In the injection molding, the position of the chain cloth at the time of injection molding is fixed, and the chain cloth is pressed by the chain pressing member. However, since the surface of the chain cloth is provided with a waterproof layer made of a synthetic resin, and the chain pressing member that presses the edge portion of the chain piece that forms the pin, the tail cylinder, and the pin is pin-shaped, the pressing force is weak. Therefore, there is a problem that the position of the chain cloth is moved due to the pressure at the time of injection molding. The present invention has been completed in the above-described circumstances, and an object thereof is to provide a pull key which can surely position the position of the chain cloth at the time of molding. 151516.doc 201141412 Technical Solution to Problem The above object of the present invention can be achieved by the following constitution. (1) A zipper, comprising: a pair of layers; a pair of key rows having sprocket teeth respectively arranged along the pair (four) having a waterproof portion; and a side edge of the upper opening slider key separating from the upper side; The cylinder lock is installed on: the key =... one end of the neighboring 矣 #万之链布 does not exist on both sides of the sprocket W; and the latch, which is the one that does not exist in the chain祛 之 之 布 布 表 表 布 键 键 键 键 键 键 键 键 键 键 键 键 键 键 键 键 键 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒 筒A through hole is formed at a position between the plurality of recesses of the key cloth. (7) The pull key of (1) includes: an upper opening slider that separates a pair of key tooth rows from the upper side; and a lower opening slider' This is formed by separating the meshing of the element rows from the lower side. The recess formed in the cylindrical pin is formed such that the dimension in the width direction increases as it separates from the fastener element in the longitudinal direction of the chain cloth. (1) The zipper, wherein a plurality of recesses formed in the latch are formed, and the plurality of recesses are formed on the face of the latch According to the zipper of the present invention, since the recessed portion which is long in the longitudinal direction of the fastener fabric is formed on both the front and back sides of the tubular pin and the plug, the concave portion can be formed at the time of injection molding. Further, since the pressing area of the chain pressing member for pressing the chain cloth is larger than the pin-shaped chain pressing member of the prior art, the position of the key cloth at the time of injection molding can be surely fixed. Therefore, the position of the chain cloth at the time of injection molding can be made. 1515I6.doc 201141412 is more stable, so the mounting strength of the pin and the pin relative to the chain can be greatly improved. Moreover, since the pressing area of the chain pressing member is large, the amount of resin used can be reduced, and the manufacturing cost can be reduced. EMBODIMENT OF THE INVENTION Hereinafter, each embodiment of the pull key of the present invention will be described in detail based on the drawings. In the following description, regarding the chain cloth, the front side is opposite to the front side of the paper surface of Fig. i, and the back side is opposite to Fig. 1.
