1357308 九、發明說明 【發明所屬之技術領域】 本發明，係關於具備有公構件及母構件之帶扣。詳細 之，係關於用來將帶子之至少一端，或者兩條帶子彼此連 結、分離之帶扣。 【先前技術】 金屬製之帶扣，係具有重量感，外表看起來會給予好 像很堅固之印象，並且會給予高級感。因此，爲了對皮包 等增添附加價値，被要求金屬製之帶扣。 作爲應如此要求之帶扣，習知有：於文獻1 (韓國公 開新型97-2665 9號公報）所揭示之帶扣。該帶扣，係由 公構件及母構件所構成。公構件，係由：於底板突設卡合 銷之本體部、及可朝相互接近、離開之方向移動地設置於 該本體部之兩側，並且具有滑嵌於卡合銷的卡合孔之一對 卡合構件、及將該一對卡合構件往相互離開之方向彈壓之 一對螺旋彈簧、及將此等一對卡合構件及一對螺旋彈簧保 持於本體部之蓋構件、以及將該蓋構件固定於本體部之固 定螺釘所構成。 對於將公構件卡合於母構件，係將公構件插入於母構 件。如此一來，公構件之一對卡合構件會抗拒螺旋彈簧之 彈壓力而相互朝內側移動後，插入直到預定位置時，會往 外側移動而卡合於母構件。 對於解除公構件與母構件之卡合，係使一對卡合構件 -4- 1357308 抗拒螺旋彈簧之彈壓力而相互朝內側移動，而解除來自母 構件之卡合後，將公構件從母構件拔出。藉此，可使卡合 解除。 【發明內容】 〔發明所欲解決之問題〕 在上述文獻1記載之帶扣，係因公構件由：本體部、 及一對卡合構件、及一對螺旋彈簧、及蓋構件、以及固定 螺釘所構成，故零件件數很多。 因此，在進行組裝之際，因需要：將一對卡合構件配 置於本體部之兩側，且，使各卡合構件之卡合孔滑嵌於本 體部之卡合銷後，將一對螺旋彈簧配置於此等的卡合構件 之間，而將一對卡合構件往相互離開之方向彈壓，並在最 後，從此等之上面蓋上蓋構件而將蓋構件以固定螺釘固定 於本體部之作業，故有花費組裝工時之問題。 本發明之主要目的，係提供一種可解決如此之問題， 可削減零件件數及降低組裝工時之帶扣。 〔用以解決問題之手段〕 本發明之帶扣，係具備有：筒狀之母構件、及可插入 於該母構件而卡合之公構件，上述公構件，係具有本體部 、及卡合構件、以及彈性構件，上述本體部，係以金屬或 摻入金屬粉之樹脂材所形成，且具有帶安裝部及從該帶安 裝部突出之基部，上述基部，係具有收容上述卡合構件的 -5- 1357308 一部分之收容部、及從該收容部使上述卡合構件露出之開 口，上述卡合構件，係以金屬或摻入金屬粉之樹脂材所形 成，且可朝上述基部的上述收容部之內外方向移動地被收 容，並且具有可卡合於上述母構件之卡合部，上述彈性構 件，係將上述卡合構件朝向上述收容部之外側彈壓，並且 容許上述卡合構件往內側移動，之帶扣，其特徵爲：上述 彈性構件，係收容於上述收容部內，且具有卡止於上述基 部的一部分之止拔部。 根據該結構，彈性構件，係具備有卡止於基部的一部 分之止拔部，因此將彈性構件收容於收容部內時，彈性構 件之止拔部就會被卡止於基部的一部分。如此一來，彈性 構件，係將卡合構件朝向收容部之外側彈壓，並且容許卡 合構件往內側移動，因此藉由卡合構件往內外移動，可將 公構件對於母構件卡合、解除^ 根據本發明之帶扣，只要將彈性構件收容於收容部內 ，彈性構件之止拔部就會具有止拔之功能而被組裝入，因 此與以往之帶扣相較，可削減零件件數，因而亦可降低組 裝工時。 在本發明之帶扣中，上述彈性構件，係上述卡合構件 往上述收容部之內外方向移動時，與上述卡合構件之移動 連動而可移動地被保持於上述卡合構件，爲較理想。 根據該結構，由於彈性構件可與卡合構件之移動連動 地被保持於卡合構件，因此可確實地進行卡合構件往內方 移動及往外方移動。 -6- 1357308 在本發明之帶扣中，上述卡合構件，係具有保持上述 彈性構件之保持部，而彈性構件，係具有被保持於上述卡 合構件的上述保持部之被保持部、及設在該被保持部的上 述公構件插入方向端及反插入方向端之一對止拔部，該等 一對止拔部被卡止於形成在上述基部的上述收容部內之卡 止部，爲較理想。 根據該結構，在卡合構件，設有保持彈性構件之保持 部，而在彈性構件，設有被保持於卡合構件的保持部之被 保持部，因此藉由使被保持部保持於保持部，可使彈性構 件簡單地保持於卡合構件。 又，在彈性構件的被保持部之兩端，亦即，公構件插 入方向端及反插入方向端分別設有止拔部，因此將保持著 彈性構件之卡合構件收容於基部之收容部內時，彈性構件 之一對止拔部就會被卡止於形成在基部的收容部內之卡止 部。亦即，卡合構件，係夾著保持著彈性構件之保持部， 而藉由插入方向端及反插入方向端的兩端之止拔部，卡止 於基部之卡止部，因此可使卡合構件以穩定的姿勢卡止於 基部’並且作成卡合構件不易從基部脫落之構造。 在本發明之帶扣中，上述一對止拔部，係藉由從上述 被保持部隨著朝向上述卡合構件之反收容方向往相互分離 之方向傾斜之傾斜片所形成，爲較理想。 根據該結構，將保持著彈性構件之卡合構件，從基部 之開口收納於收容部內時，就會藉由基部之開口，一邊將 形成一對止拔部之傾斜片往相互接近之方向彈性變形一邊 1357308 收納下去。不久，傾斜片通過開口時，傾斜片就會彈性恢 復，並卡止於基部之開口緣，藉此，卡合構件係被抑止從 基部脫落。因此，只將保持著彈性構件之卡合構件，從基 部之開口收納於收容部內，就可將卡合構件組裝入基部， 所以組裝作業亦可極簡單地進行。 在本發明之帶扣中，上述彈性構件，係於上述一對止 拔部之間具有彈性變形部，而上述基部，係具有於內部具 有上述收容部之上板及下板，並以壁部連結該等上板及下 板’且可將上述彈性構件之彈性變形部抵接於該壁部，爲 較理想。 根據該結構，基部，係具有上板及下板，並以壁部連 結該等上板及下板，且可將彈性構件之彈性變形部抵接於 該壁部，故被賦予彈性力，又，該彈性變形部位於止拔部 之間’故在將卡合構件朝內側移動時，可使卡合構件以穩 定的姿勢往內側移動，更且，作用於卡合構件之往內側的 力量消失時，藉由彈性構件之彈性恢復力，卡合構件係以 穩定的姿勢恢復到原來的位置。 在本發明之帶扣中，上述彈性構件，係在上述彈性變 形部接觸於上述壁部時，會使上述止拔部接觸於上述基部 的上述開口之周緣，爲較理想。 根據該結構，在彈性變形部接觸於壁部時，會使止拔 部接觸於基部的開口之周緣，亦即，卡合構件係在朝外側 被彈壓後之狀態下定位於基部的預定位置，因此可維持穩 定的卡合狀態》 -8- 1357308 【實施方式】 〔發明之實施形態〕 以下，參照圖面說明本發明之一實施形態。 〔實施形態之結構〕 第1圖係本實施形態的帶扣之分解立體圖。第2圖係 構成本實施形態的帶扣的公構件之分解立體圖。第3圖係 顯示構成公構件之卡合構件與彈性構件的組裝狀態之立體 圖。 本實施形態之帶扣1，係用以將帶子2 (例如’手提 包之肩帶等）之端部2A、2B連結' 分離者，而具備有： 母構件B、及可插入該母構件B且可拔出地所設置之公構 件A。 (公構件A) 公構件 A，係具備有：本體部10、及一對卡合構件 30 '以及一對彈性構件50。此等之中，本體部10及一對 卡合構件3 0係藉由金屬之壓鑄成形所形成，而一對彈性 構件50係藉由具有彈性的樹脂材之射出成形所形成。 作爲金屬，係可舉出例如鋁、不鏽鋼、鎂、鈦、鐵、 銅 '鋅、或者此等的合金等之金屬。其中，也以鋁、鎂、 鈦等之輕金屬或此等之合金來形成爲較理想。 作爲具有彈性的樹脂材，係可舉出例如聚縮醛、聚醯 胺、聚丙烯等之合成樹脂。 -9- 1357308 (本體部1 o) 本體部10，係具有帶安裝部11、及從該帶安裝部11 突出之基部21。 帶安裝部1 1，係由：兩側之側框1 2、及將該兩側之 側框12的兩端間連結之兩支連結桿13、14、以及在該兩 支連結桿1 3、1 4之間架在側框1 2之中間連結桿1 5所構 成。因此，藉由將帶子2之端部2A掛繞於中間連結桿15 之周圍，可調節帶子2之長度。 基部2 1，係具備有：從帶安裝部1 1之連結桿1 4朝向 公構件A之插入方向突出成形之上板22及下板23、以及 將該上板22及下板23的前端間連結之端面板24，而呈現 具備有將卡合構件30之一部分收容於被此等圍住的內部 之收容部25之平板狀。 在此，公構件A之插入方向，係指對於帶安裝部11 之連結桿14，與側框12延伸之方向相反方向（第1圖中 上方向）。又，反插入方向，係指對於連結桿14，側框 I2延伸之方向（第1圖中下方向）。又，內側，係表示朝 向帶扣1的寬幅方向之中心側，而外側，係表示其相反方 向。 如第4圖所示，於上板22及下板23間，在與插入方 向正交之寬幅方向大致中央位置，設置有連結上板22及 下板23間，並從連結桿14延伸至端面板24之兩支壁部 26，藉由該兩支壁部26將收容部25分割成左右。又，此 係亦可爲1支壁部26。在各收容部25 A、25B之外側，形 -10- 1357308 成有用以將卡合構件3 0從基部21之外部收容於收容部 25 A、25Β內之開口 27。開口 27，係在上板22與下板23 之間，及於帶安裝部1 1及端面板24所形成。於此，在帶 安裝部1 1側與端面板24側之收容部2 5內，具備有後述 ' 的彈性構件50之止拔部52 .卡合之卡止部27A。又，從開 口 27係露出有卡合構件30，且該露出之部分係作爲卡合 部3 3所形成^ I 各壁部26，係從連結桿1 4隨著朝向端面板24，往外 - 側彎曲而接近開口 27的周緣之後，使分離地所形成。亦 即，成形中間部往外側突出之山形形狀。從各壁部26之 最突出端朝向開口 27 —體地形成作爲導引部之導引突條 28。如第4圖所示，其中一方之卡合構件30係被形成在 下板23之導引突條28所導引，而另一方係藉由形成在未 圖示的上板22之導引突條所導引。又，關於導引突條， 亦可形成於上板22及下板23之兩板。 (卡合構件3 0 ) 卡合構件30，係可朝基部21的收容部25A、25B之 ' 內外方向移動地被收納，因此往內方移動時，卡合構件30 ' 就會進入收容部25內，而從那個狀態往外方移動時，從 開口 2 7露出的卡合構件3 0之比例就會變多。卡合構件3 0 ，係具有：卡合構件本體31、及與該卡合構件本體31之 內面側一體地且呈板狀地延伸設置之支撐片34、以及與該 支撐片34 —體成形且將彈性構件50保持之保持部35。 -11 - 1357308 卡合構件本體3 1，係將外側面形成隨著朝向插入方向 而朝內側彎曲成弧狀之操作面32，並且在反插入方向端形 成有可與母構件B的被卡合部72卡合之卡合部33。 支撐片34，係於卡合構件本體31之內面插入方向端 及反插入方向端在卡合構件3 0之一側面，朝向往收容部 25內收容之際的收容方向（與開口 27面對面之內面側） 突出形成比卡合構件本體31的厚度還更薄之矩形板狀。 此係亦可使接連於支撐片3 4。 保持部3 5，係設於各支撐片3 4，且藉由朝對於插入 方向及收容方向正交之方向突出之兩個保持軸36所形成 。保持軸3 6，係在被收容於收容部2 5 A、2 5 B內之狀態下 ，朝向基部21之上板22或下板23延伸，保持軸36與卡 合構件本體3 1之內面空出間隔而形成，於其間隔後述的 彈性構件5 0之一部分進入而被卡止。 (彈性構件5 0 ) 彈性構件5 0，係將卡合構件3 0朝向收容部2 5 A、2 5 B 之外側彈壓，並且容許卡合構件3 0往內側移動，因此被 保持在卡合構件30，並且將卡合構件30從基部21之開口 27收容於收容部25A、25B內時，具有卡止於基部21的 一部分之止拔部52。 具體上，具有：被保持在卡合構件30的保持部35之 被保持部51、及設置在該被保持部51的插入方向端及反 插入方向端之一對止拔部52、以及在一對止拔部52之大 -12- 1357308 致中間位置設置於被保持部5 1之彈性變形部5 3。 被保持部51，係具備有：被保持在卡合構件本體31 的內面與保持部35之間之第1被保持片51A、及從該第1 被保持片51A之兩端朝向內側（與卡合構件本體31相反 側）彎曲而延伸之第2被保持片5 1 B。 在將被保持部5 1保持於保持部3 5之狀態下，保持軸 36的前端與上板22或下板23之間隔，係比彈性構件50 之高度還窄，因此，在被收容於收容部2 5內之狀態中， 彈性構件5 0並不會從保持軸3 6脫落。 一對止拔部52，係藉由從被保持部5 1的第2被保持 片5 1 B之前端朝向卡合構件3 0側彎曲而延伸且隨著朝向 卡合構件3 0之反收容方向而往互相分離的方向傾斜之傾 斜片52A所構成。此等之傾斜片52A，係將卡合構件30 從基部21之開口 27收容於收容部25A、25B內之際，一 邊朝相互接近之方向彈性變形一邊收納於收容部25 A、 2 5 B內之後，彈性恢復而將其前端卡止於基部21的開口 27之周緣。因此，彈性構件50之插入方向長度，係比開 口 27之插入方向長度還更長。傾斜片52A彈性變形之際 ，根據變形之程度，第2被保持片51B也會變形。 彈性變形部5 3，係藉由在被保持部5 1的第1被保持 片5 1 A之中間位置從兩個保持軸3 6之間隨著朝向內側而 漸漸朝離開之方向傾斜之一對彈性夾持片53A所構成。該 一對彈性夾持片5 3 A之前端，係成形大致球形狀，並且分 別抵接基部2 1的壁部26之山形傾斜面。 -13- 1357308 傾斜片52A的前端之位置，係在卡止於開口 27的卡 止部27A之狀態下，比保持軸3 6的內側端更延伸到卡合 構件本體31側，而保持軸36與彈性構件50之第1被保 持片5 1 A係位於收容部2 5內。在此，爲了維持卡合構件 3 〇與彈性構件5 0之卡合，彈性構件5 0之第1被保持片 5 1 A與保持部3 5卡合之面，位於比開口 27之端緣更內側 ’亦即，位於收容部2 5內爲較理想。 (母構件B) 母構件B，係藉由金屬之壓鑄成形所形成，而具有： 表壁61、背壁62、以及於兩側具有連結表壁61及背壁62 的側壁63之扁平四角筒狀之筒體64。又，在此使用之金 屬’係與形成公構件A之本體部10或卡合構件30之金屬 相同，但非相同材料亦可。 在筒體64，於一端形成可插入公構件A的卡合構件 3〇之插入口 65，而於另一端形成帶安裝部66，且於內部 形成從插入口 65朝向另一端收納公構件A之收納空間67 °帶安裝部66’係藉由使帶子2之端部2B插通之帶插通 孔所形成。 在側壁6 3 ’朝向表壁6 1及背壁62之內部呈矩形地切 缺形成有：使公構件A之操作面32往母構件B的外部露 出之開口部7 1。在開口部7 1之反插入方向端，形成有： 可卡合公構件A的卡合部33之被卡合部72。 -14- 1357308 〔本實施形態之作用.效果〕 對於組裝公構件A，首先，如第4圖所示，使彈性構 件5 0保持於卡合構件3 0。對此，將彈性構件5 0之第1被 保持片51A嵌入於卡合構件30之卡合構件本體31與保持 部3 5之間。如此一來，彈性構件5 0，其往卡合構件3 0的 收容方向之移動係藉由卡合構件本體31及保持部3 5所限 制’又’往插入方向之移動係藉由第2被保持片51B抵接 於保持部3 5所限制。亦即，往收容方向之移動限制，係 藉由使彈性構件5 0不會離開卡合構件本體3 1地來限制， 而往插入方向之移動限制，係藉由彈性構件5 0在對於插 入方向之反插入方向側，在對於反插入方向之插入方向側 ’與卡合構件3 0之保持部3 5分別卡合而被限制。藉此， 彈性構件5 0 ’係對於卡合構件3 〇在被限制移動之狀態下 被保持。 因而’由於在卡合構件30，設置有保持彈性構件50 之保持部35’而在彈性構件50，設置有被保持在卡合構 件30的保持部35之被保持部51，因此藉由使被保持部 5 1保持於保持部3 5，可使彈性構件50簡單地保持於卡合 構件3 0。 在此，對於彈性構件5 0，預先準備卡合構件3 0之支 撐片3 4成爲下側者（第4圖之右側）、及成爲上側者（ 第4圖之左側）。因如此爲之，故不需要準備左右對稱相 反之構件，且組裝錯誤也不易發生。 如此地將保持彈性構件5 0之卡合構件3 0，如第5圖 -15- 1357308 所示，從基部21之開口 27收容於收容部25A、25B內< 將卡合構件30從基部21之開口 27收容於收容 25A、25B內時’就會藉由基部21之開口 27，將形成彈 構件5 0的一對止拔部5 2之傾斜片5 2 A —邊朝相互接近 方向彈性變形一邊收容。不久，傾斜片5 2 A通過開口 時’如第6圖所示’傾斜片5 2 A就會彈性恢復，且卡止 設在基部21之開口 27的周緣之卡止部27A。在開口 之周緣中’卡止部27A’係比在開口 27的插入方向之 度，具有較長之空間’而彈性構件5 0的傾斜片52 A之 端抵接於該處而卡合。 此時，由於彈性構件5 0之彈性變形部5 3即一對彈 夾持片53A係已經在夾著基部21的壁部26之山形斜面 狀態下被抵接，因此藉由該一對彈性夾持片5 3 A對於彈 構件5 0賦予往外側之彈性力爲較理想。因此，藉由該 性力，將傾斜片52A以密著之狀態卡止於基部21的開 27之周緣，因此可防止卡合構件30從基部21脫出。 該狀態中，由於將彈性構件50保持於卡合構件30 並將彈性構件50之止拔部52以密著之狀態卡止於開口 的周緣之卡止部27A，因此彈性構件50之止拔部52具 止拔之功能，而卡合構件30不易從基部21脫落。 而且，由於彈性構件50的被保持部51之兩端，亦 ，公構件A之插入方向端及反插入方向端分別設有止拔 5 2，因此彈性構件5 0之一對止拔部5 2被卡止於基部 之開口 27周緣。亦即，由於卡合構件30，係夾著保持 部 性 之 27 於 27 長 前 性 之 性 彈 Ρ 27 有 即 部 2 1 3DO 彈 -16- 1357308 性構件50之保持部35，藉由插入方向端及反插入方向端 的兩端之止拔部52，被卡止於基部21的開口 27之周緣， 因此可使卡合構件3〇以穩定的姿勢卡止於基部21，並且 可形成卡合構件30不易簡單地從基部21脫落之構造。 • 因此’在組裝公構件A之際，只將保持彈性構件5 〇 之卡合構件30’從基部21之開口 27收納於收容部25A、 2 5 B ’就可將卡合構件3 0裝入於基部2 1，所以組裝作業 ^ 亦可極簡單地進行。 • 又’如第7圖所示’將卡合構件3 0往內側移動時， 就會以彈性構件50之一對彈性夾持片53 a沿著壁部26之 對稱的山形傾斜面被擴張之狀態來移動卡合構件3〇，因此 卡合構件30可平行地移動，且可使卡合構件3〇以穩定的 姿勢往內側移動，又’作用於卡合構件3 0之往內側的力 量沒有時，藉由彈性構件5 0之一對彈性夾持片5 3 A的彈 性恢復力’彈性夾持片53A就會恢復到原來的形狀，一邊 φ 與山形傾斜面滑接，一邊將卡合構件30往原來的位置移 動，故卡合構件3 0係以穩定的姿勢恢復到原來的位置。 因此，可將卡合構件30之移動以穩定的姿勢確實地進行 〇 在卡合構件30移動之際’形成於上板22或下板23 之導引突條滑接於一對彈性夾持片53A之間而被導引。 對於使如此地組裝之公構件A卡合於母構件B，係將 公構件A之基部21及卡合構件3〇從母構件b之插入口 65插入於收納空間67。如此一來，將卡合構件3〇插入於 -17- 1357308 收納空間67內時，卡合構件30係藉由母構件B之側壁 63 —邊往內側彈性變形一邊插入。不久，將卡合構件3 0 之卡合部33插入到超過母構件B的側壁63之位置時，卡 合構件3 0就會往外側彈性恢復。如此一來，將卡合構件 3〇之卡合部33卡合於母構件B之被卡合部72。亦即，將 公構件A卡合於母構件B。在第5圖中，以虛線顯示卡合 後的狀態之母構件B。 又，對於解除公構件A與母構件B之卡合，係將從母 構件B之開口部7 1露出的公構件A之操作面3 2往內側按 壓。如此一來，由於卡合構件30之卡合部33會從母構件 B之被卡合部72脫落，因此在該狀態下將公構件A從母 構件B拔出時，就可解除兩者之卡合。 如此的構造之帶扣中，由於公構件A係由本體部1〇 、及一對卡合構件30、以及一對彈性構件50所構成，因 此相較於以往的帶扣，可減低零件件數。亦即，即使相較 於以往的帶扣，也不需要蓋構件或固定螺釘等，所以可削 減零件件數。因此，只將保持彈性構件5 0之卡合構件3 〇 ，從基部2 1之開口 2 7收納於收容部2 5 A ' 2 5 B，就可組 裝公構件A，所以亦可謀求降低組裝工時。 原本，母構件B、及公構件A之中本體部1〇及—對 卡合構件3 0，係以金屬所形成，所以可形成作爲金屬製之 帶扣。因此，可提供可給予具有重量感的印象之帶扣。 〔變形例〕 -18- 1357308 此外，本發明並非限定於在上述實施形態 之帶扣，也包含如下之變形例。 例如，亦可爲於第8圖 '第9圖及第10 造之帶扣。顯示於此等的圖之帶扣，係對於上 ，彈性構件50、卡合構件30、基部21及母構. 同。又，關於與上述實施形態同樣的構成要素 符號，並省略其說明。 關於彈性構件50，雖然被保持部5 1及止赶 上述實施形態相同，但是彈性變形部5 3之形 彈性變形部5 3，係形成具有：從被保持部5 1 入方向端）朝向反插入方向而與第1被保持部 行地延伸，並從第1被保持部5 1 A之大致中間 朝向反插入方向而往內側彎曲的彎曲片53B、 片53B之前端朝向插入方向而與第1被保持片 行地延伸之底座片53C之形狀。底座片53C， 第1被保持片51A的中間位置之長度，且其兩 面。 基部2 1，係形成在兩支壁部2 6之間具有湖 狀。亦即，將上板22、下板23及端面板24以

Description of the Invention [Technical Field of the Invention] The present invention relates to a buckle provided with a male member and a female member. More specifically, it relates to a buckle for connecting and separating at least one end of the strap or the two straps to each other. [Prior Art] The metal buckle has a sense of weight, and the appearance looks like a strong impression, and gives a sense of quality. Therefore, in order to add an additional price to the bag, etc., a metal buckle is required. As a buckle which is required to be so required, there is a buckle disclosed in the document 1 (Korea Publication No. 97-2665-9). The buckle is composed of a male member and a female member. The male member is disposed on the main body of the engaging pin on the bottom plate, and is disposed on both sides of the main body portion so as to be movable toward and away from each other, and has an engaging hole that is slidably engaged with the engaging pin. a pair of engaging members, and a pair of coil springs that bias the pair of engaging members away from each other, and a cover member that holds the pair of engaging members and the pair of coil springs in the main body portion, and The cover member is fixed to a fixing screw of the body portion. For engaging the male member to the female member, the male member is inserted into the female member. As a result, one of the male members moves toward the inner side against the elastic force of the coil spring against the elastic force of the coil spring, and when inserted into the predetermined position, it moves outward to be engaged with the female member. When the engagement between the male member and the female member is released, the pair of engaging members -4- 1357308 are prevented from moving toward each other against the elastic pressure of the coil spring, and after the engagement from the female member is released, the male member is removed from the female member. Pull out. Thereby, the engagement can be released. [Problem to be Solved by the Invention] The buckle according to the above-mentioned document 1 is a male member, a main body portion, a pair of engaging members, a pair of coil springs, a cover member, and a fixing screw. Because of this, the number of parts is large. Therefore, when assembling, it is necessary to arrange a pair of engaging members on both sides of the main body portion, and to engage the engaging holes of the engaging members in the engaging pin of the main body portion, and then to couple The coil spring is disposed between the engaging members, and the pair of engaging members are biased in a direction away from each other, and finally, the cover member is covered from the upper surface and the cover member is fixed to the main body portion by a fixing screw. Work, so there is a problem with the assembly work time. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a buckle that can solve such problems and can reduce the number of parts and reduce assembly time. [Means for Solving the Problem] The buckle of the present invention includes a tubular female member and a male member engageable with the female member, and the male member has a main body portion and a snap fit a member and an elastic member, wherein the body portion is formed of a metal or a resin material doped with metal powder, and has a belt mounting portion and a base portion protruding from the belt mounting portion, wherein the base portion has a housing member for housing the engaging member -5- 1357308 A part of the accommodating portion and an opening for exposing the engaging member from the accommodating portion, wherein the engaging member is formed of metal or a resin material doped with metal powder, and the accommodating member can be placed toward the base portion The inner and outer portions are movably accommodated and have an engaging portion engageable with the female member, and the elastic member biases the engaging member toward the outer side of the accommodating portion and allows the engaging member to move inward The buckle is characterized in that the elastic member is housed in the accommodating portion and has a detaching portion that is locked to a part of the base portion. According to this configuration, since the elastic member is provided with the retaining portion that is locked to a part of the base portion, when the elastic member is housed in the accommodating portion, the elastic member retaining portion is locked to a part of the base portion. In this way, the elastic member elastically presses the engaging member toward the outer side of the accommodating portion, and allows the engaging member to move to the inner side. Therefore, the male member can be engaged and disengaged from the female member by the engaging member moving inside and outside. According to the buckle of the present invention, since the elastic member is housed in the accommodating portion, the detaching portion of the elastic member has a function of being detached and assembled, so that the number of parts can be reduced as compared with the conventional buckle. It also reduces assembly time. In the buckle according to the present invention, it is preferable that the elastic member is movably held by the engaging member when the engaging member moves in the inner and outer directions of the accommodating portion in conjunction with the movement of the engaging member. . According to this configuration, since the elastic member can be held by the engaging member in conjunction with the movement of the engaging member, the engaging member can be surely moved inward and moved outward. In the buckle of the present invention, the engaging member has a holding portion for holding the elastic member, and the elastic member has a held portion held by the holding portion of the engaging member, and a pair of the male member insertion direction end and the reverse insertion direction end of the held portion, the pair of removal portions being locked to the locking portion formed in the housing portion of the base portion, More ideal. According to this configuration, the engaging member is provided with the holding portion for holding the elastic member, and the elastic member is provided with the held portion held by the holding portion of the engaging member, so that the held portion is held by the holding portion. The elastic member can be simply held by the engaging member. Further, at both ends of the held portion of the elastic member, that is, the male member insertion direction end and the reverse insertion direction end are respectively provided with the stopper portions, when the engagement member holding the elastic member is housed in the housing portion of the base portion One of the elastic members is locked to the locking portion formed in the housing portion of the base portion. In other words, the engaging member sandwiches the holding portion that holds the elastic member, and the locking portion at both ends of the insertion direction end and the reverse insertion direction end is locked to the locking portion of the base portion, thereby allowing the engagement portion to be engaged. The member is locked to the base portion in a stable posture and is configured such that the engaging member is not easily detached from the base portion. In the buckle of the present invention, the pair of the stopper portions are preferably formed by the inclined piece which is inclined from the holding portion toward the direction in which the engaging member is separated from the opposite direction. According to this configuration, when the engaging member that holds the elastic member is housed in the accommodating portion from the opening of the base portion, the inclined pieces forming the pair of the detaching portions are elastically deformed toward each other by the opening of the base portion. I put it in 1357308. Soon, when the inclined piece passes through the opening, the inclined piece elastically recovers and is locked to the opening edge of the base, whereby the engaging member is restrained from falling off from the base. Therefore, since only the engaging member holding the elastic member is housed in the accommodating portion from the opening of the base portion, the engaging member can be assembled into the base portion, so that the assembly work can be extremely easily performed. In the buckle of the present invention, the elastic member has an elastic deformation portion between the pair of the stopper portions, and the base portion has the upper plate and the lower plate of the accommodation portion inside, and the wall portion It is preferable to connect the upper and lower plates and to abut the elastic deformation portion of the elastic member to the wall portion. According to this configuration, the base portion has the upper plate and the lower plate, and the upper plate and the lower plate are coupled to each other by the wall portion, and the elastic deformation portion of the elastic member can be brought into contact with the wall portion, so that the elastic force is imparted, and The elastic deformation portion is located between the removal portions. Therefore, when the engagement member is moved inward, the engagement member can be moved inward in a stable posture, and the force acting on the inner side of the engagement member disappears. At the time, the engaging member is restored to the original position in a stable posture by the elastic restoring force of the elastic member. In the buckle of the present invention, it is preferable that the elastic member contacts the peripheral edge of the opening of the base portion when the elastic deformation portion contacts the wall portion. According to this configuration, when the elastic deformation portion comes into contact with the wall portion, the stopper portion comes into contact with the periphery of the opening of the base portion, that is, the engagement member is positioned at a predetermined position of the base portion in a state of being biased toward the outside, [Embodiment] [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Further, this may be one wall portion 26. On the outer side of each of the accommodating portions 25A, 25B, the shape -10- 1357308 is used to accommodate the engaging member 30 from the outside of the base portion 21 in the opening 27 in the accommodating portions 25 A, 25A. The opening 27 is formed between the upper plate 22 and the lower plate 23, and is formed by the tape mounting portion 11 and the end plate 24. Here, in the accommodating portion 25 on the side of the tape mounting portion 1 1 and the end plate 24 side, a locking portion 52 of the elastic member 50, which will be described later, and a locking portion 27A that is engaged are provided. Further, the engaging member 30 is exposed from the opening 27, and the exposed portion is formed as the engaging portion 33, and the wall portion 26 is formed from the connecting rod 14 toward the end panel 24, outward-side. After being bent to approach the circumference of the opening 27, it is formed separately. That is, the shape of the mountain shape in which the intermediate portion is formed to protrude outward. Guide projections 28 as guide portions are integrally formed from the most protruding end of each wall portion 26 toward the opening 27. As shown in Fig. 4, one of the engaging members 30 is guided by the guide protrusions 28 formed on the lower plate 23, and the other is guided by the guide plates formed on the upper plate 22 (not shown). Guided. Further, the guide protrusions may be formed on the upper plate 22 and the lower plate 23. (Interlocking member 30) The engaging member 30 is movably accommodated in the inner and outer directions of the accommodating portions 25A and 25B of the base portion 21. Therefore, the engaging member 30' enters the accommodating portion 25 when moving inward. When moving from the state to the outside, the ratio of the engaging members 30 exposed from the opening 27 is increased. The engaging member 30 has an engaging member body 31, and a supporting piece 34 extending integrally with the inner surface side of the engaging member body 31 and extending in a plate shape, and integrally formed with the supporting piece 34 And the elastic member 50 holds the holding portion 35. -11 - 1357308 The engaging member body 31 is formed with an operation surface 32 which is curved inwardly toward the insertion direction toward the insertion direction, and is formed at the end in the reverse insertion direction to be engaged with the female member B. The engaging portion 33 of the portion 72 is engaged. The support piece 34 is attached to the one side of the engaging member 30 on the inner surface insertion direction end and the reverse insertion direction end of the engaging member main body 31, and faces the receiving direction in the housing portion 25 (facing the opening 27). The inner surface side protrudes into a rectangular plate shape which is thinner than the thickness of the engaging member body 31. This system can also be connected to the support piece 34. The holding portion 35 is formed on each of the support pieces 34, and is formed by two holding shafts 36 that protrude in a direction orthogonal to the insertion direction and the housing direction. The holding shaft 36 is extended toward the upper plate 22 or the lower plate 23 of the base 21 in a state of being housed in the accommodating portions 2 5 A, 2 5 B, and the inner surface of the holding shaft 36 and the engaging member body 3 1 is held. The vacant space is formed, and one of the elastic members 50, which will be described later, enters and is locked. (Elastic member 50) The elastic member 50 biases the engaging member 30 toward the outside of the accommodating portions 2 5 A and 2 5 B, and allows the engaging member 30 to move inward, thereby being held by the engaging member 30. When the engaging member 30 is received in the accommodating portions 25A and 25B from the opening 27 of the base portion 21, the engaging member 30 has a detaching portion 52 that is locked to a part of the base portion 21. Specifically, it has a held portion 51 held by the holding portion 35 of the engaging member 30, and a pair of the insertion portion 52 provided at the insertion direction end and the reverse insertion direction end of the held portion 51, and The intermediate position of the large portion -12-1357308 of the stopper portion 52 is set to the elastic deformation portion 53 of the held portion 51. The held portion 51 includes a first held piece 51A held between the inner surface of the engaging member main body 31 and the holding portion 35, and an inner side (toward from both ends of the first held piece 51A) The second held piece 5 1 B that is bent and extended on the opposite side of the engaging member body 31. In a state where the held portion 55 is held by the holding portion 35, the distance between the front end of the holding shaft 36 and the upper plate 22 or the lower plate 23 is narrower than the height of the elastic member 50, so that it is accommodated in the housing. In the state inside the portion 2 5, the elastic member 50 does not fall off from the holding shaft 36. The pair of the stopper portions 52 are bent from the front end of the second held piece 5 1 B of the held portion 51 toward the engaging member 30 side and are oriented toward the opposite direction of the engaging member 30. The inclined piece 52A is inclined in a direction separating from each other. In the slanting piece 52A, the engaging member 30 is housed in the accommodating portion 25 A, 2 5 B while being elastically deformed in the direction in which the engaging member 30 is received from the opening 27 of the base portion 21 in the accommodating portions 25A and 25B. Thereafter, the elasticity is restored and the front end is locked to the periphery of the opening 27 of the base portion 21. Therefore, the length of the insertion direction of the elastic member 50 is longer than the length of the opening direction of the opening 27. When the inclined piece 52A is elastically deformed, the second held piece 51B is also deformed depending on the degree of deformation. The elastically deformable portion 53 is inclined by gradually moving toward the direction of separation from the two holding shafts 36 toward the inner side by the intermediate position of the first held piece 5 1 A of the held portion 51. The elastic holding piece 53A is constituted. The front ends of the pair of elastic holding pieces 5 3 A are formed into a substantially spherical shape and abut against the mountain-shaped inclined faces of the wall portions 26 of the base portion 21, respectively. -13- 1357308 The position of the front end of the inclined piece 52A extends to the side of the engaging member body 31 more than the inner end of the holding shaft 36 in a state of being locked to the locking portion 27A of the opening 27, while the holding shaft 36 is held. The first held piece 5 1 A of the elastic member 50 is located in the accommodating portion 25 . Here, in order to maintain the engagement between the engaging member 3 〇 and the elastic member 50, the surface of the first holding piece 5 1 A of the elastic member 50 that is engaged with the holding portion 35 is located at the edge of the opening 27 The inner side, that is, it is preferably located in the housing portion 25. (Female member B) The female member B is formed by die-casting of metal, and has: a watch wall 61, a back wall 62, and a flat square cylinder having side walls 63 connecting the watch wall 61 and the back wall 62 on both sides. Shaped cylinder 64. Further, the metal used herein is the same as the metal forming the main body portion 10 of the male member A or the engaging member 30, but may be of the same material. In the cylindrical body 64, the insertion opening 65 of the engaging member 3A into which the male member A can be inserted is formed at one end, and the belt mounting portion 66 is formed at the other end, and the male member A is housed inside from the insertion opening 65 toward the other end. The storage space 67° belt attachment portion 66' is formed by a tape insertion hole through which the end portion 2B of the strap 2 is inserted. An opening portion 71 in which the operation surface 32 of the male member A is exposed to the outside of the parent member B is formed in a rectangular shape in the side wall 63 and the back wall 62. At the end in the reverse insertion direction of the opening portion 7 1 , an engaged portion 72 of the engaging portion 33 of the male member A is formed. -14- 1357308 [Operation and effect of the present embodiment] For assembling the male member A, first, as shown in Fig. 4, the elastic member 50 is held by the engaging member 30. On the other hand, the first held piece 51A of the elastic member 50 is fitted between the engaging member main body 31 of the engaging member 30 and the holding portion 35. As a result, the movement of the elastic member 50 in the direction in which the engaging member 30 is accommodated is restricted by the engaging member body 31 and the holding portion 35, and the movement in the insertion direction is performed by the second The holding piece 51B is abutted by the holding portion 35. That is, the movement restriction in the accommodating direction is restricted by the elastic member 50 not leaving the engaging member body 31, and the movement in the insertion direction is restricted by the elastic member 50 in the insertion direction. The side of the reverse insertion direction is engaged with the holding portion 35 of the engaging member 30 in the insertion direction side of the reverse insertion direction, and is restricted. Thereby, the elastic member 50' is held in a state where the engaging member 3 is restrained from moving. Therefore, since the engaging member 30 is provided with the holding portion 35' for holding the elastic member 50, the elastic member 50 is provided with the held portion 51 held by the holding portion 35 of the engaging member 30, so that it is The holding portion 51 is held by the holding portion 35, and the elastic member 50 can be simply held by the engaging member 30. Here, in the elastic member 50, the support piece 34 of the engagement member 30 is prepared in advance as the lower side (the right side of Fig. 4) and the upper side (the left side of Fig. 4). Because of this, it is not necessary to prepare the left and right symmetrical components, and assembly errors are not easy to occur. The engaging member 30 of the elastic member 50 is held in the housing portion 25A, 25B from the opening 27 of the base portion 21 as shown in Figs. 5-15-1357308. The engaging member 30 is removed from the base portion 21 When the opening 27 is received in the housings 25A, 25B, the inclined pieces 5 2 A of the pair of the stopper portions 5 2 forming the elastic member 50 are elastically deformed toward each other by the opening 27 of the base portion 21 Take it on the side. When the inclined piece 5 2 A passes through the opening, the inclined piece 5 2 A is elastically restored as shown in Fig. 6, and the locking portion 27A provided at the periphery of the opening 27 of the base portion 21 is locked. In the peripheral edge of the opening, the locking portion 27A' has a longer space than the insertion direction of the opening 27, and the end of the inclined piece 52A of the elastic member 50 abuts therewith and engages. At this time, since the elastic deformation portion 5 of the elastic member 50, that is, the pair of elastic holding pieces 53A has been abutted in the state of the mountain-shaped inclined surface sandwiching the wall portion 26 of the base portion 21, the pair of elastic clips are thereby It is preferable that the holding piece 5 3 A imparts an elastic force to the outside of the elastic member 50. Therefore, by the force, the inclined piece 52A is locked to the periphery of the opening 27 of the base portion 21 in a sealed state, so that the engaging member 30 can be prevented from coming off from the base portion 21. In this state, since the elastic member 50 is held by the engaging member 30 and the retaining portion 52 of the elastic member 50 is locked to the locking portion 27A at the periphery of the opening, the retaining portion of the elastic member 50 is removed. The 52 has a function of stopping, and the engaging member 30 is not easily detached from the base 21. Moreover, due to the both ends of the held portion 51 of the elastic member 50, the insertion direction end and the reverse insertion direction end of the male member A are respectively provided with the stopper 52, and thus one of the elastic members 50 is opposite to the stopper portion 5 2 It is locked to the periphery of the opening 27 of the base. That is, due to the engaging member 30, the retaining portion 27 is held by the retaining portion 27, and the long-term elastic impeller 27 has the retaining portion 35 of the member 2 1 3DO--16-1357308 member 50, by the insertion direction. The stopper portion 52 at both ends of the end and the reverse insertion direction end is locked to the periphery of the opening 27 of the base portion 21, so that the engaging member 3 can be locked to the base portion 21 in a stable posture, and the engaging member can be formed. 30 is a structure that is not easily detached from the base portion 21. • Therefore, when the male member A is assembled, only the engaging member 30' holding the elastic member 5 is accommodated in the accommodating portion 25A, 2 5 B ' from the opening 27 of the base portion 21, and the engaging member 30 can be loaded. At the base 2 1, the assembly work ^ can also be carried out extremely simply. • As shown in Fig. 7, when the engaging member 30 is moved inward, the elastic holding piece 53a is expanded toward the symmetrical mountain-shaped inclined surface of the wall portion 26 by one of the elastic members 50. The state moves the engaging member 3〇, so that the engaging member 30 can move in parallel, and the engaging member 3 can be moved to the inside in a stable posture, and the force acting on the inner side of the engaging member 30 is not At the time of the elastic restoring force of the elastic holding piece 5 3 A by one of the elastic members 50, the elastic holding piece 53A is restored to the original shape, and the engaging member is slid while the φ is in contact with the inclined surface of the mountain shape. The 30 moves to the original position, so that the engaging member 30 returns to the original position in a stable posture. Therefore, the movement of the engaging member 30 can be surely performed in a stable posture. When the engaging member 30 is moved, the guide protrusion formed on the upper plate 22 or the lower plate 23 is slidably coupled to the pair of elastic holding pieces. Guided between 53A. When the male member A thus assembled is engaged with the female member B, the base portion 21 and the engaging member 3A of the male member A are inserted into the housing space 67 from the insertion opening 65 of the female member b. As a result, when the engaging member 3 is inserted into the -17 - 1357308 accommodating space 67, the engaging member 30 is inserted while being elastically deformed toward the inner side by the side wall 63 of the female member B. Soon, when the engaging portion 33 of the engaging member 30 is inserted beyond the side wall 63 of the female member B, the engaging member 30 elastically recovers to the outside. In this manner, the engaging portion 33 of the engaging member 3 is engaged with the engaged portion 72 of the female member B. That is, the male member A is engaged with the female member B. In Fig. 5, the female member B in the engaged state is shown by a broken line. Further, when the engagement between the male member A and the female member B is released, the operation surface 3 2 of the male member A exposed from the opening portion 7 1 of the female member B is pressed inward. As a result, since the engaging portion 33 of the engaging member 30 is detached from the engaged portion 72 of the female member B, when the male member A is pulled out from the female member B in this state, both of them can be released. Engage. In the buckle of such a structure, since the male member A is composed of the main body portion 1A, the pair of engaging members 30, and the pair of elastic members 50, the number of parts can be reduced as compared with the conventional buckle. . In other words, even if the buckle is not used in comparison with the conventional buckle, the number of parts can be reduced. Therefore, only the engaging member 3 保持 holding the elastic member 50 is accommodated in the accommodating portion 2 5 A ' 2 5 B from the opening 27 of the base portion 2 1 , so that the male member A can be assembled, so that the assembler can be reduced. Time. Originally, the main body member B and the male member A have the main body portion 1 and the pair of engaging members 30, which are formed of metal, so that a buckle made of metal can be formed. Therefore, it is possible to provide a buckle that can give an impression of being heavy. [Modification] -18 - 1357308 Further, the present invention is not limited to the buckle of the above embodiment, and includes the following modifications. For example, it can also be a buckle made in Figure 8 'Fig. 9 and 10'. The buckle shown in the figures is the same as the upper, elastic member 50, the engaging member 30, the base 21, and the mother. The same components as those of the above-described embodiment are denoted by the same reference numerals, and their description will be omitted. The elastic member 50 is the same as the above-described embodiment, but the elastic deformation portion 53 of the elastic deformation portion 53 is formed to have a reverse insertion from the end portion of the held portion 5 1 toward the end. The first piece to be held is extended in the direction of the first held portion, and the curved piece 53B and the front end of the piece 53B are bent toward the insertion direction from the substantially middle of the first held portion 5 1 A toward the reverse insertion direction. The shape of the base piece 53C extending in a row is maintained. The base piece 53C is the length of the intermediate position of the first held piece 51A, and has both sides. The base portion 2 1 is formed in a lake shape between the two wall portions 26 . That is, the upper plate 22, the lower plate 23, and the end plate 24 are divided in the middle. Further, the wall portion 26 is formed in a linear shape from the connecting rod panel 24, and the base of the elastic deformation portion 53 is abutted thereto. In the female member B, the partition wall 68 is integrally formed in the storage space 67 from the vicinity of the insertion port portion 66. The configuration shown in the configuration of the partitions 6 8 is not the same as that of the embodiment, and the same portion 5 2 is different from the shape. One end of the plug (5 1 Α substantially flat position with and from the bend 5 1 A is substantially flat with a cross-end forming arc 0 slit 29 in the shape of a wide direction 14 toward the end piece 53C of the two 6 5 The structure of the front wall 61 and the back wall 62 of the member B is connected to the belt, so that it can be reinforced, and also has a function as a guide for the male member A. When the member A is inserted into the female member B, the slit 9 of the male member A is inserted with the partition wall 68 as a guide, so that the male member a can be prevented from being inserted in an inclined posture. Further, the engaging member 30 The support piece 34 is formed at the insertion direction end and the reverse insertion direction end, and the groove portion therebetween is slidably coupled to the guide protrusion 28 provided on the base portion 21, thereby being guided by the β according to the modification. In the state shown in FIG. 9, that is, in a state in which the engaging member 30 is housed in the accommodating portions 25A and 25B of the base portion 21, when the engaging member 30 is moved inward, as shown in FIG. As shown, the curved piece 5 3 弹性 of the elastic deformation portion 5 3 is elastically deformed so as to be close to the base piece 53C and larger than the base piece 53C. The parallel posture prevents the engaging member 30 from being tilted. That is, the base piece 53C does not largely move in the state of the abutting wall portion 26, and only the bent piece 53 is elastically deformed to be substantially the same as the base piece 53C. In the parallel posture, the engaging member 30 can be prevented from tilting. Although the above embodiment is configured such that the retaining portion 52 of the elastic member 50 is locked to the periphery of the opening 27 of the base portion 21, it may not necessarily be elastic. The retaining portion 52 of the member 50 is locked to the periphery of the opening 27 of the base portion 21. For example, a projection as a locking portion may be provided in the receiving portion 25 of the base portion 21, and the retaining portion 52 of the elastic member 50 may be provided. The retaining shaft 36 of the retaining portion 35 may be one. Further, in addition to the structure in which the retaining portion 35 of the engaging member 30 forms the retaining shaft -20-1357308 36 protruding from the support piece 34, It is also conceivable that the support piece 34 is provided with a hole portion penetrating in the front-rear direction as the holding portion ′, and the protrusion that is engaged with the hole portion in the elastic member 50 is held as the held portion ′. Although the above embodiment The pair of the stopper portions 52 are elastically deformed, respectively, but may be, for example, a structure in which only one side is elastically deformed. In this case, the other side of the stopper portion is first locked, and then rotated about the center thereof. However, in the above-described embodiment, the configuration of the male member A has the structure of the engaging member 30 on both sides of the main body portion 10, but it is also possible to In the above-described embodiment, the main body portion 10 and the engaging member 30 are made of metal, but the main body portion 10 and the engaging member 30 are made of metal. The metal can also be formed of a resin material such as aluminum, stainless steel, magnesium, titanium, iron, copper, or a metal powder such as an alloy thereof. When the metal powder or the like is incorporated in the resin material, the surface state can be completed to have the same texture and weight as the metal, and thus a product equivalent to that of the metal can be obtained. In the above embodiment, the female member B is also made of metal, but the material constituting the female member B is not limited. For example, it may be formed by mixing the same metal powder as the material of the main body portion 10 or the engaging member 30 forming the male member A or a metal material of a different type. In the above embodiment, the elastic member 50 is made of a resin material having elasticity. However, the material having elasticity is not limited to the resin material. For example, a metal strip can also be formed by bending. In the above embodiment, the engagement portion 33 of the male member A is engaged, and the -21 - 1357308 is engaged with the structure of the engaged portion 72 provided at the end of the opening portion 71 of the female member B, but is not limited thereto. It can also be other structures. For example, the engaging portion may be provided on the front and back of the male member A, and the engaging portion may be engaged with the front wall 61 and the back wall 62 in the interior of the storage space 67 of the female member B. The structure of the engaged portion. In the above embodiment, the belt attachment portions 11 and 66 are formed in the male member A and the female member B, respectively, but the female member B may not have the belt attachment portion. That is, the female member B can also be directly fixed to other members. In the above embodiment, the tape is not limited to a belt-like belt, and may be a string without a wide width.
