Description

帶扣buckle

本發明係關於一種帶扣,該帶扣具有彼此可嚙合及可脫嚙之插頭及插座且經配置為使帶子、皮帶或其他構件之單獨部自連結狀態斷接。The present invention relates to a buckle having plugs and sockets that are engageable and disengageable from each other and configured to disconnect a separate portion of the strap, belt or other member from the engaged state.

在先前技術中,舉例而言,專利文獻1揭示一種經配置為可拆卸地連結兩個連結目標之帶扣。該帶扣具有插頭及插座。該插頭具有:帶子***部,其為具有可供帶子或其類似者***及連結之帶子***孔的附接部;及一對腿部,其在帶子***部之寬度方向上自帶子***部之兩個端部分彼此平行地延伸。每一腿部經配置為可彈性地變形,且具有一對嚙合突出部,其經形成為在其前端部分處在表背方向(front and back direction)上突起。可供插頭裝配之插座亦具有帶子***部,該帶子***部具有形成於其中之帶子***孔,且自帶子***部之一個端部分一體地設置中空插頭裝配部。插頭裝配部具有前端部分被敞開之上板及下板,且操作開口在寬度方向上形成於上板及下板之兩個側邊緣處。操作開口之基端部分被形成有可與***於插頭裝配部中之一對腿部之一對嚙合突出部嚙合的被嚙合部分。面朝下板之帶子***部的插座之端部分被形成有與帶子***部之縱向方向平行地延伸的孔部分,且設置自該孔部分之周邊邊緣部分突起至插座中且經配置為可與插頭之嚙合突出部嚙合的突起部。因此,在插頭及插座之嚙合狀態下,插頭之嚙合突出部曝露於孔部分。 專利文獻2中所揭示之帶扣亦具有與專利文獻1相似之基本組態。然而,開口通口在帶子***部側處設置於插座中,且插座之下板設有連續開口邊緣,該連續開口邊緣具有自該開口通口朝向用於插頭之***通口凹入的凹形形狀。藉此,插頭之嚙合突出部的前端表面及背表面曝露於開口通口。 專利文獻1:日本專利申請公告第2004-160166A號 專利文獻2:日本專利申請公告第2011-254929A號 根據專利文獻1中所揭示之帶扣,形成於插座中之孔部分設置於與插頭之***方向正交的表面上。因此,在插座受到諸如廢棄物及雪之異物阻塞時,該等異物卡塞於插座中而不自孔部分排出,使得可能無法向插座中***且無法與嚙合突出部嚙合。 又,根據專利文獻2中所揭示之帶扣,開口通口在帶子***部側處形成於插座中。因此,即使在插座中存在一些異物時,該等異物亦在插頭***後就在帶子***部側處自插座之開口通口排出。然而,因為開口通口大,所以存在異物更可能被引入至插座中之問題。此外,在插頭及插座之嚙合狀態下異物自具有開口通口之凹形形狀的開口邊緣被引入且堵塞於一對腿部之間時,插頭之嚙合突出部歸因於異物而無法在彼此靠近之方向上擺動,使得可能無法釋放嚙合狀態。In the prior art, for example, Patent Document 1 discloses a buckle configured to detachably couple two joint targets. The buckle has a plug and a socket. The plug has: a strap insertion portion which is an attachment portion having a strap insertion hole into which a strap or the like is inserted and coupled; and a pair of leg portions which are self-contained in the width direction of the strap insertion portion The two end portions extend parallel to each other. Each of the legs is configured to be elastically deformable, and has a pair of engaging projections formed to protrude at a front end portion thereof in a front and back direction. The socket for plug assembly also has a strap insertion portion having a strap insertion hole formed therein, and a hollow plug fitting portion is integrally provided from one end portion of the strap insertion portion. The plug fitting portion has a front end portion that is opened by the upper and lower plates, and an operation opening is formed at both side edges of the upper and lower plates in the width direction. The base end portion of the operation opening is formed with an engaged portion engageable with the engagement projection of one of the pair of legs inserted into the plug fitting portion. An end portion of the socket of the tape insertion portion facing the lower plate is formed with a hole portion extending in parallel with the longitudinal direction of the tape insertion portion, and is provided to protrude from the peripheral edge portion of the hole portion into the socket and configured to be compatible A projection that engages the engaging projection of the plug. Therefore, in the engaged state of the plug and the socket, the engaging projection of the plug is exposed to the hole portion. The buckle disclosed in Patent Document 2 also has a basic configuration similar to that of Patent Document 1. However, the opening port is provided in the socket at the side of the tape insertion portion, and the lower plate of the socket is provided with a continuous opening edge having a concave shape from the opening opening toward the insertion opening for the plug shape. Thereby, the front end surface and the back surface of the engaging projection of the plug are exposed to the opening. Patent Document 1: Japanese Patent Application Publication No. 2004-160166A Patent Document 2: Japanese Patent Application Publication No. 2011-254929A. The buckle disclosed in Patent Document 1, the hole portion formed in the socket is disposed in insertion with the plug On a surface that is orthogonal to the direction. Therefore, when the socket is blocked by foreign matter such as waste and snow, the foreign matter is jammed in the socket without being discharged from the hole portion, so that it may not be inserted into the socket and cannot be engaged with the engaging projection. Further, according to the buckle disclosed in Patent Document 2, the opening port is formed in the socket at the side of the tape insertion portion. Therefore, even if some foreign matter is present in the socket, the foreign matter is discharged from the opening of the socket at the side of the tape insertion portion after the plug is inserted. However, since the opening port is large, there is a problem that foreign matter is more likely to be introduced into the socket. Further, when the foreign matter is introduced from the opening edge of the concave shape having the open port and is blocked between the pair of legs in the meshing state of the plug and the socket, the engaging projections of the plug cannot be brought close to each other due to the foreign matter. The direction of the swing makes it impossible to release the engaged state.

在下文中,將參考圖1至圖13來描述根據本發明之第一說明性實施例之帶扣10。如圖1至圖3所顯示,帶扣10具有插頭12及經配置為與插頭12裝配及嚙合之插座14,且經配置為附接至帶子、皮帶或一對其他構件以便使其任意地連結及解除連結。在下文中,將插頭12***至插座14中或與插座14分離之方向稱為前後方向,將插頭12***至插座14中之方向稱為前方向,且將被連結插頭12與插座14分離之方向稱為後方向。前後方向亦為相對於圖2之紙張表面的上下方向。將插座14之一對操作孔50 (其稍後將被描述)彼此面對且插頭12之一對腿部20彼此面對的方向稱為左右方向。左右方向亦為相對於圖2之紙張表面的左右方向。將與左右方向及前後方向正交之方向稱為表背方向或厚度方向。 插頭12係由諸如聚縮醛、聚醯胺、聚丙烯或其類似者之合成樹脂一體地形成。如圖11至圖13所顯示,插頭12具有待***至插座14中之腿部20、定位於腿部20之前端部分20a處的前端連結部分23,及一體地設置於較靠近前端連結部分23之前端之位置處的嚙合突出部(嚙合部分) 22。與一對腿部20之基端部分20b整合的附接部24設置於與嚙合突出部22相對之側處。附接部24經配置為用作可供帶子、皮帶或其他預定構件***及連結之部。 一對腿部20自附接部24對稱地突起。每一腿部20具有一外腿片件25及一內腿片件27。前端連結部分23與在外腿片件25及內腿片件27之突起方向上的前端整合,使得外腿片件25及內腿片件27之前端彼此連結。外腿片件25在突起方向上之中心部分處在左右方向上向外鼓出,且鼓出部分成為用於釋放插頭12之嚙合狀態的操作部分26。內腿片件27在左右方向上相對於外腿片件25定位於內側處,且內腿片件在左右方向上之厚度小於外腿片件25。又,內腿片件27相比於外腿片件25以較大曲率在左右方向上向外彎曲。 形成於腿部20之前端部分20a處的前端連結部分23在表背方向上具有小於操作部分26之厚度,在厚度方向上定位於外腿片件25及內腿片件27之中心部分處,且在前後方向上延伸。嚙合突出部22定位於前端連結部分23之前端處,且在表背方向上朝向兩個側突起。嚙合突出部22設有面朝腿部20之基端部分20b側的嚙合台階部分22a。嚙合台階部分22a經形成為可與稍後將被描述的插座14之被嚙合部分52之被嚙合台階部分52a嚙合。 在一對腿部20之基端部分20b側處,外腿片件25及內腿片件27之基端係分別由自附接部24之兩個端一體地延伸的臂部分28連結。藉此,每一腿部20具有由外腿片件25、內腿片件27、前端連結部分23及臂部分28環繞之空間29。各別臂部分28定位於為附接部24之兩個端的一對腿部20之基端部分20b處,具有朝向左右方向上之中心部分相對於腿部20之突起方向傾斜的直線形狀,且形成大致V型形狀。中心部分處彼此面對之臂前端部分28a彼此以預定間隔而隔開,且作為導引部分30 (其稍後將被描述)之狹縫32之端部分而彼此面對。 在臂部分28之臂前端部分28a彼此面對的左右方向上之中心部分處,經配置為將插頭12之***操作導引至插座14中的導引部分30係與腿部20之突起方向平行地設置。導引部分30具有自臂前端部分28a在前後方向上一體地延伸且在左右方向上彼此平行地彼此面對之細長U型形狀。導引部分30之前端部分30a連結於腿部20之前端連結部分23附近,使得導引部分30之U型形狀之空間被形成為狹縫32。前端部分30a相比於腿部20之前端連結部分23之前端位於在前後方向上稍微較靠近基端部分20b之位置處。 附接部24具有設置於插頭12之端部分處的第一桿33及經配置為連結一對腿部20之基端部分20b的第二桿34,此等桿被一體地設置且在左右方向上彼此平行,且帶子***孔24a形成於該等桿之間。又,由第二桿34及臂部分28環繞之部分形成空間,其組態帶子***孔24b。第一桿33經形成為在表背方向上之寬度與附接部24在表背方向上之寬度相等,且第二桿34在表背方向上定位於附接部24之前表面側處,且在表背方向上薄於第一桿33。 插座14亦係由諸如聚縮醛、聚醯胺、聚丙烯或其類似者之合成樹脂一體地形成。如圖4至圖10所顯示,插座14具有可供插頭12之腿部20***的中空裝配部40,及設置於與裝配部40之***通口40a相對之側處的附接部42。附接部42被形成有可供帶子、皮帶或其他預定構件***之帶子***孔42a,且設有經配置為連結帶子構件或其類似者之連結桿44。 插座14之裝配部40具有上表面部45及下表面部46,其經配置為彼此以預定間隔而面對且形成插頭12之***空間。面朝***通口40a的上表面部45及下表面部46之端部分形成在前後方向上朝向***通口40a之中心傾斜的大致V型形狀。在左右方向上的插座14之側表面設有經配置為彼此面對之側壁部48,且在前後方向上的側壁部48之中心部分被形成有可使腿部20之操作部分26曝露的操作孔50。操作孔50經形成為彎曲成凹形形狀以便在左右方向上彼此靠近,且亦經形成使得操作部分26c可在左右方向上曝露。 經配置為導引插頭12之***操作的導引槽56係分別在裝配部40之上表面部45及下表面部46的內表面上由***通口40a連續地形成。導引槽56自***通口40a設置於前後方向上,經形成為面朝***通口40a之側寬的喇叭形狀,且經配置為在前後方向上導引滑動操作,其中導引部分30裝配於導引槽56中。在裝配部40之上表面部45及下表面部46中的靠近附接部42之位置處,可供一對嚙合突出部22嚙合之一對被嚙合部分52係設置為在裝配部40中之空間中以在表背方向上突起之方式彼此面對。每一被嚙合部分52具有可與嚙合突出部22之嚙合台階部分22a以彼此面對之方式嚙合的被嚙合台階部分52a,且嚙合台階部分22a及被嚙合台階部分52a具有與腿部20之突起方向正交的表面。被嚙合部分52被形成有側表面部52b,其相對於前後方向傾斜且係設置為朝向附接部42彼此靠近。側表面部52b經配置為在***插頭12後與嚙合突出部22接觸且使腿部20在彼此靠近之方向上彈性地變形。 下表面部46設有在帶子***孔42a附近在表背方向上敞開之一對通孔54,且面朝***通口40a的通孔54之邊緣部分係設置為連續且與各別被嚙合部分52之周邊邊緣部分齊平。面朝帶子***孔42a的插座14之端表面被端表面壁部60封閉,且端表面壁部60之中心部分被形成有用於使帶子***孔42a與裝配部40之內部彼此連通的開口62。開口62以插座14之上表面部45與下表面部46之間的寬度在前後方向上敞開,且其在左右方向上之寬度窄於彼此面對的一對通孔54之內邊緣部分之間的間隔。 開口62被形成有開口凹形部分58,其具有凹形形狀且自面朝附接部42的下表面部46之端邊緣延續。開口凹形部分58僅被設置用於下表面部46,且被面朝附接部42的上表面部45之端部分覆蓋。開口凹形部分58經形成為在左右方向上之寬度與開口62相同,且定位於通孔54之間。因此,為下表面部46之部分的側邊緣部分64形成於各別通孔54與開口凹形部分58之間。又,開口凹形部分58在左右方向上之寬度W1窄於一對腿部20之對向側表面之間的在左右方向上之寬度W2,且開口凹形部分58定位於一對腿部20突出至被形成有開口凹形部分58之下表面部46的部位之間。亦即,如圖2之後視圖所顯示,第一說明性實施例之帶扣10經形成為在左右方向上對稱,開口凹形部分58在附接部44側處在左右方向上形成於下表面部46之中心處,且一對腿部20定位於開口凹形部分58之兩側處。各別通孔54設置於嚙合突出部22可露出之位置處。同時,在第一說明性實施例之帶扣10中,開口凹形部分58形成於下表面部46上。然而,當開口凹形部分58形成於上表面部45上時,開口凹形部分58設置於一對腿部20突出至上表面部45的部位處。 隨後,描述第一說明性實施例之帶扣10的嚙合操作及使用方法。首先,為了將帶子構件或其類似者附接至帶扣10之插頭12,將連結用帶子構件(未圖示)之端部分自背表面側***至插頭12之附接部24之帶子***孔24b中,經由第二桿34之外周邊自前表面側***至插頭12之帶子***孔24a中,在帶子***孔24a之背表面側處與帶子構件重疊,且接著拉出使得可自由地調整長度。同時,待附接至插座14之帶子構件或其類似者(未圖示)不可調整地連結至一個連結桿44。 如圖1及圖2所顯示,當嚙合插頭12及插座14時,將插頭12推動至插座14中,其中插頭12之腿部20面對插座14之裝配部40之***通口40a。當將腿部20***至裝配部40中時,腿部20之嚙合突出部22之外表面接觸被嚙合部分52之側表面部52b,且腿部20經***為在彼此靠近之方向上彈性地變形。當進一步推動插頭12時,嚙合突出部22與側表面部52b分離,彈性變形之一對腿部20恢復至原始狀態,且一對腿部20之嚙合突出部22之嚙合台階部分22a面對被嚙合部分52之被嚙合台階部分52a,使得嚙合突出部22與被嚙合部分52彼此嚙合。 在將插頭12***至插座14中後,即使在諸如廢棄物及雪之異物位於插座14中時,亦隨著***插頭12而將插座14中之異物自與帶子***孔42a連通之開口凹形部分58及開口62排出。 為了解除連結插頭12與插座14,當自外側按壓一對操作部分26時,使插頭12之嚙合突出部22彈性地變形至嚙合突出部不面對插座14之被嚙合部分52的位置。在此狀態下,當插頭12及插座14在彼此分開之方向上彼此稍微相對地移動時,由於腿部20之彈性力,嚙合突出部22被沿著被嚙合部分52之側表面部52b推動而離開嚙合位置。藉此,嚙合狀態被容易地釋放。 又,在插頭12及插座14之嚙合狀態下,即使在諸如雪之異物自開口凹形部分58或開口62被引入時,由於插頭12之一對腿部20之嚙合突出部22遠離開口凹形部分58 (其間介入有側邊緣部分64),故亦由於側邊緣部64之寬度而縮減待引入於嚙合突出部22之間的諸如雪之異物的量。藉此,當使插頭12脫嚙時,腿部20可容易地由於側邊緣部分64之寬度而在彼此靠近之方向上擺動,使得有可能安全地執行脫嚙操作。
