201132312 六、發明說明： 【發明所屬之技術領域】 本發明係關於繩索頭構件，係關於作爲繩索頭止擋件 ，以單體裝設於繩索端部，或作爲帶扣的插座或插頭裝設 於繩索端部之零件。 【先前技術】 以往，繩索頭止擋件係除了繩狀的構件（繩索）的端 部處理，即繩索端部的保護、綻開防止等之功能，亦被利 用於確保被覆切斷痕跡之達到的外觀性。在這種的繩索頭 止擋件，主要是利用合成樹脂製的繩索頭構件。 在繩索頭構件，爲了裝設於繩索端部，而利用機械性 夾持繩索端部之構造、或將棘狀或齒狀的部分刺到繩索端 部這樣的構造（專利文獻1等）。 帶扣係以一對的插頭及插座所構成，在將繩狀的構件 (繩索）或帶狀的構件（皮帶）的端部彼此連接之情況， 或將繩索、皮帶等連接於其他零件之情況時使用。 其中，在裝設於皮帶的端部之情況，除了利用夾持皮 帶之構造外，亦多數利用捲繞於形成在插頭或插座的複數 個桿後加以固定之構造。 另外，在使用於項鍊等的繩索端部彼此連接之帶扣， 利用與前述繩索頭構件相同之構造，這種的帶扣係能夠將 作爲帶扣之結合構造附加於繩索頭止擋件者來加以使用。 [專利文獻1 ]日本特許3 1 5 1 4 1 3號公報 -5- 201132312 【發明內容】 [發明所欲解決之課題] 作爲裝設有前述繩索頭構件之繩索’具有將纖維進行 編織所形成之繩狀物（編織繩）、或將彈性體材料細長地 成形之矽繩（成形繩）等。 其中，若爲編織繩之類，藉由刺入形成於繩索頭構件 之棘狀或齒狀的部分，能夠使棘狀或齒狀的部分咬入到纖 維而進行確實的卡止。 但，在矽繩等的彈性體材料製的情況，會有棘狀或齒 狀的部分不易咬入，即使作爲壓迫狀態可暫時地卡止，有 當張力施加於繩索時直徑減少而造成脫落之虞（線脫落） 外，還有當刺入棘狀或齒狀的部分時造成斷裂之虞（線斷 裂）的情況產生。 本發明之主要目的係在於提供即使對成形繩也不易產 生線脫落、線斷裂等產生之繩索頭構件。 [用以解決課題之手段] 本發明之繩索頭構件，係爲將繩索端部予以收容並保 持之繩索頭構件，其特徵爲，具有：隔著前述繩索端部而 相對向配置之第1構件及第2構件；在隔著前述繩索端部 而相對向的狀態下，將前述第1構件及前述第2構件予以 固定之鎖定機構；自前述第1構件起立，而插通於形成在 前述繩索端部的貫通孔之插通部；以及形成於前述第2構 -6- 201132312 件，用來保持前述插通部的前端之保持部。 在此，作爲第1構件及第2構件，分別能夠利用合成 樹脂材料的成形品，若爲後述之鉸鏈連結者，則可將第1 構件及第2構件予以一體成形。 作爲自第1構件起立之保持部，能夠利用圓柱狀、角 柱狀、具寬度的板狀等、任意的柱狀或壁狀的突起形狀。 爲了避免繩索損傷，期望將保持部的角部的棱線予以圓化 〇 作爲形成於第2構件之保持部，期望能夠保持插通部 的前端並限制繩索連續方向的移動，能夠利用繩索的寬度 方向或徑方向等，與繩索的連續方向交叉之方向的階差等 (後述）。 作爲繩索，能夠利用成形繩。作爲繩索，不限於成形 繩，亦可利用編織繩等其他的繩索。 作爲形成於繩索端部之貫通孔，能夠利用斷面爲圓形 、楕圓形或長圓形的孔。爲了避免繩索的損傷，及考量作 爲成形繩之成型性’期望貫通孔避免具有角部。 在這樣的本發明，當進行對繩索端部之裝設時，解開 鎖定機構’作成將第1構件與第2構件打開的狀態，在此 狀態下，在第1構件與第2構件之間配置繩索端部。然後 ’將第1構件的插通部插通繩索端部的貫通孔，並且作成 爲使第1構件與第2構件相對向並關閉之狀態，藉由鎖定 機構將其予以固定。藉此，第1構件與第2構件被—體化 ，並且成爲繩索端部被夾持於第1構件與第2構件之間的 201132312 狀態，進行了繩索頭構件對繩索端部的裝設。 在如此所裝設之繩索頭構件，在繩索端部，會有因繩 索的連續方向的張力造成繩索端部的直徑減少之情況。但 ，即使在這種情況，也可藉由插通於繩索端部的貫通孔之 插通部，使得繩索端部不會自第1構件與第2構件之間脫 離。 特別是自第1構件起立之插通部將繩索端部朝徑方向 (與繩索的連續方向交叉之方向）貫通，並且插通部的前 端被第2構件的保持部保持成不會朝繩索的連續方向位移 。因此，可確實地防止因插通部的屈曲等所造成之繩索端 部的脫落。 根據以上內容，若依據本發明，能夠迴避對成形繩之 線脫落，並且藉由事先形成插通於貫通孔之插通部，能夠 防止以往這種藉由以棘狀次入的方式所造成之線斷裂。 在本發明，前述鎖定機構係具有：將前述第1構件的 一端及前述第2構件的一端可自由轉動地連結之鉸鏈；和 將前述第1構件及前述第2構件在相對向狀態下卡止之卡 止構造爲佳。 在這樣的本發明，藉由鉸鏈的轉動，能夠使第1構件 及第2構件自關閉的狀態移位成打開的狀態，並且，即使 在打開的狀態下，也能藉由鉸鏈，使得第1構件與第2構 件不會分離，因此，容易進行對繩索端部之裝設操作，亦 可防止遺失等產生。又，藉由卡止構造，能夠將以鉸鏈所 轉動之第1構件及第2構件在關閉的狀態下加以固定。 -8- 201132312 在本發明，前述保持部係爲形成於前述第2構件的與 前述第1構件相對向的面之凹部爲佳。 在此，作爲凹部，自前述第2構件的與前述第1構件 相對向的面凹陷即可，亦可爲貫通至前述第2構件的相反 側爲止之孔。又，凹部係爲能將插通部的前端朝繩索的連 續方向移動限制即可，朝繩索的寬度方向之移動限制並非 一定需要。因此，作爲凹部，亦可爲朝繩索的寬度方向延 伸之溝狀。 在這樣的本發明，藉由插通部的前端塡入到凹部，能 夠限制插通部的前端朝繩索的連續方向之移動。又，由於 僅在前述第2構件的表面形成凹部，故也容易進行製造。 在本發明’前述凹部係形成於一對的突條之間，該一 對突條是形成於前述第2構件的與前述第1構件相對向的 面並朝前述繩索的寬度方向延伸爲佳。 在這樣的本發明’藉由僅在前述第2構件的表面隆起 形成突條，能夠形成繩索的寬度方向的凹部，由於爲附加 的’故，比起挖去材料所製造之凹陷、溝、孔等，更容易 進行製造。 再者’保持部係能夠防止插通部無法抗衡繩索的張力 而屈曲之情況產生即可，亦可爲能自繩索連續的側（非端 部之側）抵接至插通部的前端之階差形狀。 作爲階差形狀’能夠利用使前述第2構件的與前述第 1構件相對向的面作成爲高度不同的2個區域而形成於其 間之階差、或藉由隆起形成於前述相對向的面之斷面直角 9 - 201132312 三角形的突條所形成之階差等。 在本發明，前述第1構件及前述第2構件的中的至少 其中一者，在與導入前述繩索之側的相反側，形成可與其 他繩索頭構件結合並可分離之結合構造爲佳。 在此，作爲可與其他繩索頭構件結合之結合構造，能 夠採用形成於既存的帶扣的插頭及插座之間的鎖定手段， 例如可利用側開式鎖定臂、前開式的鎖定臂、其他的凹凸 卡合構造等。 在這樣的本發明，能夠將形成有結合構造之繩索頭構 件作爲帶扣的插座及插頭中的其中任一者來發揮功能，能 夠作成爲即使裝設於成形繩也不會產生線脫落、線斷裂等 之帶扣。 【實施方式】 以下’根據圖面，說明本發明的具體實施形態。 [第1實施形態] 圖1至圖1 0係顯示本發明的第1實施形態。 在圖1中’本實施形態係爲將由合成樹脂製的成形繩 所構成之繩索1作爲項鍊來加以利用者，具有將繩索1的 端部（繩索端部9)相互地結合、分離之帶扣2。作爲此 帶扣2 ’使用依據本發明之繩索頭構件的插頭3及插座4 〇 插頭3係裝設於一方的繩索端部9，並且在與朝繩索 -10- 201132312 1延伸的側之相反側具有鎖定臂1 1及一對的導引桿1 2。 插座4係裝設於另一方的繩索端部9，並且在與朝繩索1 延伸的側之相反側形成有腔室1 9。 如圖5所示’腔室1 9係供插頭3的鎖定臂1 1及一對 的導引桿1 2插入，藉由與這些構件相互地卡合，使得插 頭3與插座4之結合變得可能。藉由這些鎖定臂n、一 對的導引桿12及腔室19，在插頭3及插座4的相互對向 的部分構成前開式的帶扣2之結合構造1 〇。 如圖2、圖3及圖5所示’插頭3係爲依據本發明之 繩索頭構件’藉由依據本發明之構造來裝設於繩索端部9 〇 插頭3係具有隔著繩索端部9而相對向配置之第！構 件3 1及第2構件3 2。第1構件31及第2構件3 2係以一 對的鉸鏈3 3連接著。第1構件3 1及第2構件3 2係以鉸 鏈3 3爲中心相互地轉動，能夠自圖2所示的打開的狀態 變化成圖1所示的關閉的狀態。 如圖5所示’藉由在使第1構件31及第2構件32打 開的狀態下’將繩索1的前端插通於鉸鏈3 3之間的開口 部分，再關閉第1構件31及第2構件32，能夠在第1構 件31與第2構件32之間夾持繩索端部9。這些第1構件 31、第2構件32及鉸鏈33係可利用藉由合成樹脂材料的 射出成形等成形爲一體者。 在第1構件3 1，於關閉的狀態下與第2構件3 2相對 向側的面形成有插通部3 6 ’隔著此插通部3 6，在絞鏈3 3 -11 - 201132312 的相反側形成有一對的卡止凹部3 5。 插通部36係爲立設於第1構件31之角柱狀的突起 可插通於如圖5所示之形成於繩索端部9的貫通孔8。 通部3 6係藉由捲繞基部之凹狀的曲面來從第1構件3 1 續地隆起，並且接近其前端之部分係在與鉸鏈3 3相反 形成有傾斜面，形成爲朝前端逐漸變細，並且前端被圓 。再者，形成於繩索端部9之貫通孔8係爲圓形斷面之 〇 卡止凹部3 5係形成於形成在第1構件3 1的側面的 狀的部分之相對向的內側面，朝第1構件3 1的側方外 形成爲階差。 在第2構件32，於關閉的狀態下與第1構件3 1相 向側的面形成有保持部3，隔著此保持部3 8，於鉸鏈 的相反側形成有一對的卡止突起34。 保持部38係具有朝插頭3的寬度方向（所裝設之 索端部9的寬度方向）延伸之一對的突條37。突條37 自第2構件3 2連續地隆起，藉由將各稜線圓化，使得 體爲帶圓之突條。 在一對的突條3 7之間，形成有朝繩索端部9的寬 方向延伸之凹部38A。當將第1構件3 1與第2構件32 成爲關閉的狀態時，前述第1構件3 1的插通部3 6的前 塡入到凹部3 8 A內，藉由一對的突條3 7，限制繩索端 9朝繩索端部9的連續方向的移動。突條37的鉸鏈33 之側面係作成爲傾斜面，自鉸鏈3 3分離的側之突條3 7 插 連 側 化 孔 壁 側 對 3 3 繩 係 全 度 作 端 部 側 的 -12- 201132312 傾斜之側面係與插通部3 6的前端的傾斜面隔著梢許間隔 相對向。又’在接近鉸鏈33的側之突條37的與鉸鏈33 分離的側之側面’會與插通部3 6的前端相抵接，能夠負 擔施加於插通部36之繩索端部9的連續方向的力。 藉由這些插通部36、突條37、保持部38，來進行繩 索端部9的移動限制。 卡止突起34係爲在前端具有箭頭狀的階差之突起， 當將第1構件3 1與第2構件3 2作成爲關閉的狀態時，箭 頭狀的前端會塡入到前述第1構件3 1的卡止凹部3 5，使 得階差相互地卡合，藉此，能夠將第1構件31與第2構 件3 2保持於關閉的狀態。 藉由這些卡止突起34及卡止凹部35，構成將以鉸鏈 33爲中心進行轉動之第1構件31及第2構件3 2在關閉 的狀態予以卡止之卡止構造。又，藉由此卡止構造（卡止 突起34及卡止凹部35)與鉸鏈33，構成在隔著繩索端部 9而相對向的狀態下將第1構件3 1及第2構件3 2予以固 定之鎖定機構3 0。 如圖2、圖4及圖5所示，插座4係爲依據本發明之 繩索頭構件，藉由依據本發明之構造來裝設於繩索端部9 〇 插座4係具有隔著繩索端部9而相對向配置之第1構 件41及第2構件42。第1構件41及第2構件42係以一 對的鉸鏈43來連接著。構成插座4之第1構件41、第2 構件42及鉸鏈43係分別與插頭3的第1構件3 1、第2 -13- 201132312 構件3 2及鉸鏈3 3相同。 又，在插座4，形成有卡止突起44、卡止凹部45、 插通部46、一對的突條47 '凹部48A、保持部48、鎖定 機構40，但這些構件係與形成在插頭3之卡止突起34 ' 卡止凹部35、插通部36、一對的突條37、凹部38A、保 持部3 8、鎖定機構3 0相同。 如此，插座4與插頭3，各自所形成之帶扣2的結合 構造10不同，即在插座4形成有腔室19，而在插頭3形 成有鎖定臂Π及一對的導引桿12，伴隨這些這些結合構 造10的差異，在第1構件31、41及第2構件32、42的 形狀上也有不同，除此以外，基本上是共通的。因此’針 對插座4之與插頭3相同的部分，省略重複之說明。 在本實施形態，於繩索1的兩端裝設著插頭3及插座 4，將此插頭3與插座4作爲帶扣2予以結合、分離’藉 此能夠利用來作爲項鍊。 在此，說明關於插頭3及插座4對繩索1的端部的裝 設。再者，在以下的說明，以將插座4裝設於繩索端部9 爲例，但在裝設插頭3之情況’操作順序也完全相同。 在圖6中，當將插座4裝設於繩索1的端部時，首先 ，將插座4的第1構件41與第2構件42作成爲打開的狀 態，自鉸鏈43之間的開口部分拉入繩索端部9(圖6的 A狀態）。其次，讓已被拉入的繩索端部9屈曲，沿著第 1構件41，使插通部46插通於形成在繩索端部9之貫通 孔8 (圖6的B狀態）。 -14- 201132312 在此狀態下’拉起第2構件42，使鉸鏈43屈曲並轉 動’朝第1構件41的上面側移動，讓第1構件41與第2 構件42隔著繩索端部9相互重疊。在此，藉由將第2構 件42朝第1構件4 1強力地按壓，使得卡止突起44塡入 到卡止凹部45 ’讓第1構件41與第2構件42在關閉的 狀態下被固定（圖7的狀態）。 在圖7中’在關閉的狀態，第1構件41與第2構件 42被一體化而形成筒狀的插座4。繩索1係將繩索端部9 收容於插座4內，並且形成爲與此連續之部分通過鉸鏈 43之間而被拉出到外部之狀態。 在此’被收容於插座4的內部之繩索端部9，係插通 部46插通於其貫通孔8，且，插通部46被突條47及保 持部48所保持，藉由對插座4可確實地固定，即自外部 的繩索1施加張力，也不會產生朝繩索1的連續方向脫離 (線脫落）。 特別是插通部46的前端受到保持部48所保持，朝繩 索端部9的連續方向移動被限制，並非所謂的單臂懸梁， 而是成爲雙臂懸梁的狀態，因此，可確實地迴避因繩索1 的張力造成插通部46撓曲以及屈曲而使繩索端部9脫離 的情況產生。 又，插通部46被圓化而不存在有角部，且貫通孔8 也爲圓形斷面之孔，因此，即使承受繩索1的張力，藉由 插通部46在繩索端部9也不會產生裂痕等，可確實地迴 避以往棘狀的構件咬入的方式這種的裂開（繩裂開）產生 -15- 201132312 再者，在前述第1實施形態，使用~對的突條3 7、 47作爲保持部38 ' 48，在這些突條之間形成凹部38A、 48A，藉此來保持插通部46的前端，但亦可採用以下所 示的變形例。 在圖8，在第2構件4 2的內側（第1構件41側）形 成有凹陷48B。凹陷48B，亦可爲連續於繩索端部9的寬 度方向之溝狀，或亦可爲平面圓形的凹陷。使用這樣的凹 陷48B，也能夠進行插通部46的前端的繩索端部9連續 方向的移動限制。 在圖9，在第2構件42的內側（第1構件41側）， 形成有貫通到外側之孔4 8 C。孔4 8 C，亦可爲連續於繩索 端部9的寬度方向之細縫狀，或亦可爲斷面圓形的孔。使 用這樣的孔48C，也能夠進行插通部46的前端的繩索端 部9連續方向的移動限制。 在圖1 〇，於第2構件42的內側（第1構件41側） ，形成有與鉸鏈43相反方向之階差48D。階差48D，亦 可爲連續於繩索端部9的寬度方向之階差，或亦可爲僅形 成於插通部46的對應部分者。使用這樣的階差48D，也 能進行插通部46的前端的繩索端部9連續方向的移動限 制。 [第2實施形態] 圖1 1係顯示本發明的第2實施形態。 -16- 201132312 本實施形態係與前述第1實施形態同樣地作爲項鍊來 使用者，在繩索1的端部裝設有成爲帶扣2之插頭3及插 座4。 這些插頭3及插座4’其基本結構是與前述第1實施 形態相同’但帶扣2的結合構造1 〇上不同。因此，以下 ’僅針對與前述第1實施形態不同之部分進行說明。 在前述第1實施形態，爲前開式卡合，但在本實施形 態’作成爲側開式卡合。即，在插頭3的插座4側，設置 一對的鎖定臂13’在插座4的腔室19內分別被卡合。在 插座4，形成有操作用開口 18，被卡合於腔室19內之鎖 定臂13自從該操作用開口 18露出一部分，藉由壓入此露 出部分’可解除卡合。再者，亦可藉由鎖定臂13的卡合 角度之設計變更’構成當一定以上之張力施加時，會自動 地卡合解除。 在這樣的本實施形態，亦可獲得與前述第1實施形態 相同的效果。 [第3實施形態] 圖1 2及圖1 3係顯示本發明的第3實施形態。 在前述第1實施形態及第2實施形態，爲了在作爲項 鍊之作成爲環狀來使用的繩索1的端部裝設成爲帶扣2之 插頭3及插座4，而在這些插頭3及插座4分別適用本發 明的繩索頭構件的結構。在本實施形態，作爲以單體裝設 於繩索1的端部之繩索頭止擋件，適用本發明的繩索頭構 -17- 201132312 件的結構。 在圖1 2及圖1 3，繩索頭止擋件5係具有隔著繩索端 部9而相對向配置之第1構件51及第2構件52。第1構 件5 1及第2構件52係以一對的鉸鏈5 3連接著。構成繩 索頭止擋件5之第1構件5〗、第2構件52及鉸鏈53，分 別係與前述第1實施形態的插頭3的第1構件3 1、第2 構件3 2及鉸鏈3 3相同。 又，在繩索頭止擋件5，形成有卡止突起54、卡止凹 部55、插通部56、一對的突條57、凹部58A、保持部58 、鎖定機構5 0，這些構件係與前述第1實施形態的形成 於插頭3之卡止突起34'卡止凹部35、插通部36、一對 的突條37、凹部38A、保持部38、鎖定機構30相同。 如此，本實施形態的繩索頭止擋件5與前述第1實施 形態的插頭3，在插頭3形成有成爲帶扣2的結合構造10 之鎖定臂1 1及一對的導引桿1 2，相對於此，在本實施形 態的繩索頭止擋件5 ’該部分僅作成爲表面1 7，在這一點 上不同，除了此差異以外，基本上是共通的。因此，針對 與前述第1實施形態的插頭3相同部分，省略重複的說明 〇 在這樣的本實施形態’也能獲得與前述第1實施形態 相同的效果。 [第4實施形態] 圖1 4係顯示本發明的第4實施形態。 -18 -

In order to attach the rope head member to the end portion of the rope, a structure in which the end portion of the rope is mechanically held or a structure in which a ratchet-like or tooth-shaped portion is stuck to the end portion of the rope is used (Patent Document 1 and the like). The buckle is composed of a pair of plugs and sockets, and when the ends of the rope-shaped member (rope) or the belt-shaped member (belt) are connected to each other, or the rope, the belt, or the like is connected to other parts. When used. Among them, in the case of being attached to the end portion of the belt, in addition to the structure for holding the belt, many of them are fixed by being wound around a plurality of rods formed in the plug or the socket. Further, in the buckle that is connected to the end portions of the ropes of the necklace or the like, the buckle structure can attach the joint structure as the buckle to the rope head stopper by the same structure as the rope head member. Use it. [Patent Document 1] Japanese Patent No. 3 1 5 1 4 1 3-5-201132312 [Problem to be Solved by the Invention] A rope which is provided with the above-mentioned rope head member has a fiber formed by knitting A rope (woven rope) or a tether (forming rope) in which an elastic material is elongated. Here, in the case of a braided rope or the like, by piercing the spine-like or tooth-shaped portion formed in the rope head member, the ratchet-shaped or tooth-shaped portion can be bitten into the fiber to perform accurate locking. However, in the case of an elastomer material such as a reins, a portion having a ratchet shape or a tooth shape is less likely to be bitten, and even if it is pressed, it can be temporarily locked, and when the tension is applied to the rope, the diameter is reduced to cause the peeling off. In addition to the 虞 (line detachment), there is also a case where a rupture (line break) is caused when a portion that is inserted into a spine or a tooth is formed. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a rope head member which is less likely to cause wire breakage, wire breakage, and the like even for a forming rope. [Means for Solving the Problem] The rope head member of the present invention is a rope head member that accommodates and holds a rope end portion, and has a first member that is disposed to face each other across the rope end portion. And a second member; a locking mechanism that fixes the first member and the second member in a state of being opposed to each other across the end portion of the rope; and is erected from the first member and inserted into the rope An insertion portion of the through hole at the end; and a holding portion formed in the second structure -6-201132312 for holding the front end of the insertion portion. Here, as the first member and the second member, a molded article of a synthetic resin material can be used, and if it is a hinge linker to be described later, the first member and the second member can be integrally molded. As the holding portion that stands up from the first member, an arbitrary columnar or wall-shaped protruding shape such as a columnar shape, a prismatic shape, or a plate shape having a width can be used. In order to avoid damage to the rope, it is desirable to round the ridge line of the corner portion of the holding portion as the holding portion formed in the second member, and it is desirable to be able to hold the tip end of the insertion portion and restrict the movement in the continuous direction of the rope, and to utilize the width of the rope. A step such as a direction or a radial direction that crosses the continuous direction of the rope (described later). As a rope, a forming rope can be utilized. The rope is not limited to a forming rope, and other ropes such as a braided rope may be used. As the through hole formed in the end portion of the rope, a hole having a circular, elliptical or oblong cross section can be used. In order to avoid damage to the rope, and to consider the moldability as a forming rope, it is desirable that the through hole avoids having a corner portion. In the present invention, when the end portion of the rope is attached, the unlocking mechanism ' is opened to open the first member and the second member. In this state, between the first member and the second member. Configure the end of the rope. Then, the insertion portion of the first member is inserted into the through hole of the end portion of the rope, and the first member and the second member are opposed to each other and closed, and are fixed by a locking mechanism. As a result, the first member and the second member are integrally formed, and the end portion of the rope is sandwiched between the first member and the second member in the state of 201132312, and the rope end member is attached to the end portion of the rope. In the rope head member thus installed, the diameter of the end portion of the rope may be reduced at the end portion of the rope due to the tension in the continuous direction of the rope. However, even in this case, the insertion portion of the through hole inserted through the end portion of the rope can prevent the end portion of the rope from coming off from between the first member and the second member. In particular, the insertion portion that stands up from the first member penetrates the end portion of the rope in the radial direction (the direction intersecting the continuous direction of the rope), and the distal end of the insertion portion is held by the holding portion of the second member so as not to be attached to the rope. Continuous direction displacement. Therefore, the fall of the end portion of the rope due to the buckling or the like of the insertion portion can be surely prevented. According to the above, according to the present invention, it is possible to avoid the detachment of the wire of the forming rope, and by forming the insertion portion inserted into the through hole in advance, it is possible to prevent the conventional method from being inserted in a ratchet manner. The line breaks. In the present invention, the lock mechanism has a hinge that rotatably connects one end of the first member and one end of the second member, and locks the first member and the second member in a relative state. The locking structure is preferred. According to the present invention as described above, the first member and the second member can be displaced from the closed state to the open state by the rotation of the hinge, and the first member can be made to be opened by the hinge even in the open state. Since the member and the second member are not separated, it is easy to perform the mounting operation on the end portion of the rope, and it is possible to prevent the occurrence of loss or the like. Further, by the locking structure, the first member and the second member that are rotated by the hinge can be fixed in a closed state. In the present invention, it is preferable that the holding portion is a concave portion formed on a surface of the second member facing the first member. Here, the concave portion may be recessed from a surface of the second member facing the first member, or may be a hole penetrating the opposite side of the second member. Further, the recessed portion may be configured to restrict the movement of the distal end of the insertion portion in the continuous direction of the rope, and the movement restriction in the width direction of the rope is not always required. Therefore, the concave portion may be a groove shape extending in the width direction of the rope. In the present invention as described above, the front end of the insertion portion can be restricted from moving in the continuous direction of the rope by the front end of the insertion portion being inserted into the concave portion. Further, since the concave portion is formed only on the surface of the second member, it is easy to manufacture. In the present invention, the concave portion is formed between a pair of ridges which are formed on a surface of the second member facing the first member and preferably extend in the width direction of the rope. In the present invention, by forming the ridges only on the surface of the second member, it is possible to form the concave portion in the width direction of the rope, and since it is additional, it is a recess, a groove, and a hole which are made of the material to be excavated. Etc. It is easier to manufacture. Further, the 'holding portion' can prevent the insertion portion from being bent against the tension of the rope, and can be a step that can be abutted from the side (non-end side) where the rope is continuous to the front end of the insertion portion. Poor shape. The step shape ' can be formed by forming a surface in which the second member faces the first member in two regions having different heights, or a step formed therebetween, or a bump formed on the opposing surface. Section Right Angle 9 - 201132312 The step difference formed by the triangular ridges. In the present invention, at least one of the first member and the second member is preferably formed on a side opposite to the side on which the rope is introduced, and a coupling structure that can be coupled to and separated from the other of the rope head members is formed. Here, as a coupling structure that can be combined with other rope head members, a locking means formed between the plug and the socket of the existing buckle can be employed, for example, a side opening type locking arm, a front opening type locking arm, and the like can be used. Concave-convex engagement structure, etc. According to the present invention, it is possible to function as one of the socket and the plug in which the cable head member having the coupling structure is formed, and it is possible to prevent the wire from falling off even when it is attached to the molding rope. Buckle for breaks, etc. [Embodiment] Hereinafter, specific embodiments of the present invention will be described based on the drawings.

The plug 3 has a cable end portion 9 therebetween. And the relative configuration of the first! The member 31 and the second member 3 2 are provided. The first member 31 and the second member 3 2 are connected by a pair of hinges 3 3 . The first member 3 1 and the second member 3 2 are mutually rotated about the hinge 3 3 , and can be changed from the open state shown in Fig. 2 to the closed state shown in Fig. 1 . As shown in FIG. 5, the first member 31 and the second member are closed by inserting the distal end of the cord 1 into the opening between the hinges 3 in a state where the first member 31 and the second member 32 are opened. The member 32 can hold the rope end portion 9 between the first member 31 and the second member 32. The first member 31, the second member 32, and the hinge 33 can be integrally formed by injection molding or the like of a synthetic resin material. In the closed state of the first member 3 1, the surface on the side opposite to the second member 32 is formed with an insertion portion 3 6 'separated by the insertion portion 3 6 in the hinge 3 3 -11 - 201132312 A pair of locking recesses 35 are formed on the opposite side. The insertion portion 36 is a columnar protrusion that is erected on the first member 31 and can be inserted into the through hole 8 formed in the rope end portion 9 as shown in Fig. 5 . The through portion 36 is continuously swelled from the first member 3 1 by the concave curved surface of the winding base, and the portion close to the front end thereof is formed with an inclined surface opposite to the hinge 33, and is formed to gradually change toward the front end. Fine, and the front end is round. Further, the through hole 8 formed in the end portion 8 of the rope has a circular cross section, and the locking recess 35 is formed on the opposite inner side surface of the portion formed on the side surface of the first member 31, and The lateral shape of the first member 3 1 is a step. In the second member 32, the holding portion 3 is formed on the surface on the side opposite to the first member 31 in the closed state, and a pair of locking projections 34 are formed on the opposite side of the hinge via the holding portion 38. The holding portion 38 has a pair of protrusions 37 extending in the width direction of the plug 3 (the width direction of the cable end portion 9 to be mounted). The ridge 37 is continuously swelled from the second member 3 2, and the ridge line is rounded so that the body is a rounded ridge. Between the pair of ribs 37, a recess 38A extending in the width direction of the rope end portion 9 is formed. When the first member 31 and the second member 32 are in a closed state, the front portion of the insertion portion 36 of the first member 3 1 is inserted into the concave portion 38A, and the pair of protrusions 3 7 The movement of the rope end 9 in the continuous direction of the rope end 9 is restricted. The side surface of the hinge 33 of the ridge 37 is formed as an inclined surface, and the side ridge 3 7 separated from the hinge 33 is inserted into the side wall side of the side wall 3 3 to the end side of the rope system -12-201132312 tilt The side surface is opposed to the inclined surface of the front end of the insertion portion 36 at a predetermined interval. Further, 'the side surface of the side of the ridge 37 that is close to the hinge 33 on the side close to the hinge 33' will abut against the front end of the insertion portion 36, and can bear the continuous direction of the rope end portion 9 applied to the insertion portion 36. Force. The movement restriction of the rope end portion 9 is performed by the insertion portion 36, the ridge 37, and the holding portion 38. The locking projections 34 are projections having an arrow-shaped step at the tip end. When the first member 31 and the second member 32 are closed, the arrow-shaped distal end is inserted into the first member 3. The locking recesses 35 of 1 allow the steps to be engaged with each other, whereby the first member 31 and the second member 32 can be held in a closed state. The locking projections 34 and the locking recesses 35 constitute a locking structure for locking the first member 31 and the second member 32 which are rotated about the hinge 33 in a closed state. By the locking structure (the locking projection 34 and the locking recess 35) and the hinge 33, the first member 3 1 and the second member 3 2 are placed in a state of being opposed to each other via the cord end portion 9 . Fixed locking mechanism 30. As shown in Figures 2, 4 and 5, the socket 4 is a rope head member according to the present invention, which is attached to the rope end portion 9 by means of the structure of the present invention. The socket 4 has a cable end portion 9 therebetween. The first member 41 and the second member 42 are disposed to face each other. The first member 41 and the second member 42 are connected by a pair of hinges 43. The first member 41, the second member 42, and the hinge 43 constituting the socket 4 are the same as the first member 31, the second -13-201132312 member 3 2, and the hinge 33 of the plug 3, respectively. Further, the socket 4 is formed with a locking projection 44, a locking recess 45, an insertion portion 46, a pair of protrusions 47', a recess 48A, a holding portion 48, and a locking mechanism 40. However, these members are formed on the plug 3. The locking projections 34' are the same as the locking recesses 35, the insertion portions 36, the pair of protrusions 37, the recesses 38A, the holding portions 38, and the locking mechanism 30. Thus, the socket 4 and the plug 3 are different from the combined structure 10 of the buckle 2 formed by the socket 4, that is, the socket 4 is formed with the chamber 19, and the plug 3 is formed with the locking arm Π and the pair of guide rods 12, accompanied by The difference between these combined structures 10 differs in the shape of the first members 31, 41 and the second members 32, 42 and is basically the same. Therefore, the description of the same portion of the socket 4 as the plug 3 will be omitted. In the present embodiment, the plug 3 and the socket 4 are attached to both ends of the rope 1, and the plug 3 and the socket 4 are coupled and separated as the buckle 2, and can be used as a necklace. Here, the attachment of the plug 3 and the socket 4 to the end of the rope 1 will be described. Further, in the following description, the socket 4 is attached to the rope end portion 9 as an example, but in the case where the plug 3 is mounted, the operation sequence is also completely the same. In Fig. 6, when the socket 4 is attached to the end of the rope 1, first, the first member 41 and the second member 42 of the socket 4 are opened, and the opening portion between the hinges 43 is pulled in. The rope end portion 9 (A state of Fig. 6). Next, the rope end portion 9 that has been pulled in is bent, and along the first member 41, the insertion portion 46 is inserted into the through hole 8 formed in the end portion 9 of the rope (state B in Fig. 6). -14- 201132312 In this state, 'the second member 42 is pulled up, and the hinge 43 is flexed and rotated' to move toward the upper surface side of the first member 41, and the first member 41 and the second member 42 are mutually separated by the cord end portion 9 overlapping. Here, the second member 42 is strongly pressed against the first member 4 1 , so that the locking projection 44 is inserted into the locking recess 45 ′ to fix the first member 41 and the second member 42 in a closed state. (State of Figure 7). In Fig. 7, in the closed state, the first member 41 and the second member 42 are integrated to form a cylindrical socket 4. The cord 1 accommodates the cord end portion 9 in the socket 4, and is formed in a state in which a continuous portion thereof is pulled out to the outside through the hinge 43. Here, the cord end portion 9 accommodated in the inside of the socket 4 is inserted into the through hole 8 through the insertion portion 46, and the insertion portion 46 is held by the protrusion 47 and the holding portion 48 by the pair of sockets. 4 can be surely fixed, that is, tension is applied from the outer rope 1, and no detachment (line drop) occurs in the continuous direction of the rope 1. In particular, the distal end of the insertion portion 46 is held by the holding portion 48, and is restricted from moving in the continuous direction of the rope end portion 9, and is not a so-called one-arm cantilever, but is in a state of a double-arm suspension beam, so that the cause can be surely avoided. The tension of the rope 1 causes the insertion portion 46 to flex and buckle to cause the rope end portion 9 to be detached. Further, the insertion portion 46 is rounded without the corner portion, and the through hole 8 is also a hole having a circular cross section. Therefore, even if the tension of the rope 1 is received, the insertion portion 46 is also at the rope end portion 9 It is possible to avoid the occurrence of cracks and the like, and it is possible to surely avoid the phenomenon in which the conventional ratcheting member bites in. The splitting (rope splitting) is generated -15-201132312. Further, in the first embodiment, the pair of protruding strips is used. 3, 47, 47 as the holding portion 38'48, the recesses 38A, 48A are formed between the ridges, whereby the front end of the insertion portion 46 is held, but the following modifications may be employed. In Fig. 8, a recess 48B is formed on the inner side (the first member 41 side) of the second member 42. The recess 48B may also be a groove that is continuous in the width direction of the end portion 9 of the rope, or may be a flat circular recess. By using such a recess 48B, it is also possible to restrict the movement of the rope end portion 9 at the tip end of the insertion portion 46 in the continuous direction. In FIG. 9, on the inner side (the first member 41 side) of the second member 42, a hole 4 8 C penetrating to the outside is formed. The hole 4 8 C may also be a slit shape continuous in the width direction of the end portion 9 of the rope, or may be a hole having a circular cross section. With such a hole 48C, the movement restriction of the rope end portion 9 at the tip end of the insertion portion 46 in the continuous direction can be performed. In FIG. 1A, a step 48D in the opposite direction to the hinge 43 is formed on the inner side (the first member 41 side) of the second member 42. The step 48D may also be a step which is continuous in the width direction of the rope end portion 9, or may be formed only in the corresponding portion of the insertion portion 46. By using such a step 48D, the movement restriction of the rope end portion 9 at the tip end of the insertion portion 46 in the continuous direction can be performed.
