例如於日本專利特開平2-131704號公報(專利文獻1)中揭示有可實現上述拉片之裝卸的拉鏈用滑件之一例。此處，一面參照圖22~圖24，一面對專利文獻1所記載之滑件進行說明。An example of a slider for a slide fastener that can realize attachment and detachment of the above-described pull tab is disclosed in Japanese Laid-Open Patent Publication No. Hei No. 2-131704 (Patent Document 1). Here, the slider described in Patent Document 1 will be described with reference to FIGS. 22 to 24 .

該專利文獻1所記載之滑件可藉由沿著於左右一對鏈帶之對向端緣所安裝的鏈齒排滑動，而使左右之鏈齒排彼此嚙合或分離。此處，將滑件為使鏈齒排嚙合而相對於鏈齒排相對移動之方向作為前方，將為使鏈齒排分離而移動之方向作為後方。The slider described in Patent Document 1 can be meshed or separated from each other by sliding the chain rows attached to the opposite end edges of the pair of left and right chain belts. Here, the direction in which the slider is meshed with the element rows and moved relative to the element rows is the front side, and the direction in which the element rows are separated and moved is the rear.

如圖22及圖23所示，專利文獻1之滑件310包含滑件本體320以及拉片360。滑件本體320係將上翼板321與下翼板322之前端部彼此利用導引柱323連接而構成。又，於上翼板321及下翼板322之左右側緣，朝向對向之下翼板322及上翼板321延設有側導板324。As shown in FIGS. 22 and 23, the slider 310 of Patent Document 1 includes a slider body 320 and a pull tab 360. The slider body 320 is configured by connecting the upper end portions of the upper blade 321 and the lower blade 322 to each other by a guide post 323. Further, on the right and left side edges of the upper blade 321 and the lower blade 322, side guide plates 324 are extended toward the opposite lower blade 322 and the upper blade 321 .

於上翼板321之上表面，懸臂狀地固定有拉片保持體330。該拉片保持體330包含：固定端部331，其自上翼板321之前端部豎起；延設部332，其自該固定端部331彎曲並向後方延伸；以及自由端部333，其自該延設部332向上翼板321側彎曲；且於拉片保持體330之自由端部333側之端面333a與上翼板321之間，形成有可使拉片360之安裝軸部360a插通之特定的插通間隙311。On the upper surface of the upper blade 321 , a tab holding body 330 is fixed in a cantilever manner. The pull tab holding body 330 includes: a fixed end portion 331 which is erected from a front end portion of the upper wing plate 321; an extended portion 332 which is bent from the fixed end portion 331 and extends rearward; and a free end portion 333 The extending portion 332 is bent toward the upper blade 321 side; and between the end surface 333a on the free end portion 333 side of the tab holding body 330 and the upper blade 321 is formed, the mounting shaft portion 360a of the tab 360 can be inserted. A specific insertion gap 311 is passed through.

又，於上翼板321之上表面側，自上翼板321之後端朝向前方形成有滑動導引溝槽325，於該滑動導引溝槽325內收容有滑動構件340與彈性構件350，其中該滑動構件340係以使上述插通間隙311開閉之方式沿著滑動導引溝槽325可滑動地配置，該彈性構件350係對滑動構件340向後方施壓。Further, on the upper surface side of the upper blade 321 , a sliding guiding groove 325 is formed from the rear end of the upper blade 321 toward the front, and the sliding member 340 and the elastic member 350 are accommodated in the sliding guiding groove 325, wherein The sliding member 340 is slidably disposed along the sliding guide groove 325 such that the insertion gap 311 is opened and closed, and the elastic member 350 presses the sliding member 340 rearward.

於此情形時，為防止滑動構件340自滑動導引溝槽325脫落，豎立設置有配置於上翼板321之後端部的卡止部326，該卡止部326藉由在將滑動構件340***至滑動導引溝槽325後被緊固，藉此成為向滑動導引溝槽325內側突出之狀態。In this case, in order to prevent the sliding member 340 from coming off the sliding guide groove 325, a locking portion 326 disposed at the rear end portion of the upper blade 321 is erected, and the locking portion 326 is inserted in the sliding member 340 After being slid to the guide groove 325, the guide groove 325 is fastened, thereby being in a state of protruding toward the inside of the slide guide groove 325.

又，滑動構件340包含配置於滑動導引溝槽325內之本體部341、及自本體部341突設之封閉部342，於該滑動構件340移動至施壓方向側之滑動端時，可藉由封閉部342而封閉(或縮小)插通間隙311。因此，在將拉片360之安裝軸部360a收容於拉片保持體330之延設部332與上翼板321之間所形成的收容空間312時，可阻止該安裝軸部360a經由插通間隙311脫落。Further, the sliding member 340 includes a main body portion 341 disposed in the sliding guide groove 325 and a closing portion 342 protruding from the main body portion 341. When the sliding member 340 is moved to the sliding end on the pressing direction side, the sliding member 340 can be borrowed. The insertion gap 311 is closed (or reduced) by the closing portion 342. Therefore, when the mounting shaft portion 360a of the tab 360 is received in the accommodating space 312 formed between the extended portion 332 of the tab holding body 330 and the upper blade 321 , the mounting shaft portion 360a can be prevented from passing through the insertion gap. 311 fell off.

於上述專利文獻1之滑件310中，當組裝滑件本體320後安裝拉片360時，如圖24所示，使拉片360之安裝軸部360a自後方抵壓於滑動構件340之封閉部342，抵抗彈性構件350之施壓力而使滑動構件340向前方滑動。藉此，拉片保持體330之自由端部333與上翼板321之間的插通間隙311開口，並且使拉片360之安裝軸部360a一面抵壓於封閉部342，一面通過已開口之插通間隙311。In the slider 310 of the above-mentioned Patent Document 1, when the slider 360 is attached after assembling the slider body 320, as shown in FIG. 24, the mounting shaft portion 360a of the tab 360 is pressed against the closing portion of the sliding member 340 from the rear. 342, sliding the sliding member 340 forward against the pressing force of the elastic member 350. Thereby, the insertion gap 311 between the free end portion 333 of the tab holding body 330 and the upper blade 321 is opened, and the mounting shaft portion 360a of the tab 360 is pressed against the closing portion 342, and the opening is opened. The gap 311 is inserted.

其後，將拉片360之安裝軸部360a向上方提拉，解除安裝軸部360a與滑動構件340之封閉部342之干擾，藉此滑動構件340受到彈性構件350施壓而移動至施壓方向側之滑動端為止，因此插通間隙311被該滑動構件340之封閉部342所封閉。藉此，形成為如下狀態：拉片360之安裝軸部360a收容於收容空間312內，且拉片360保持於拉片保持體330。Thereafter, the mounting shaft portion 360a of the tab 360 is pulled upward, and the interference between the mounting shaft portion 360a and the closing portion 342 of the sliding member 340 is released, whereby the sliding member 340 is pressed by the elastic member 350 to move to the pressing direction. The sliding end of the side is closed, so that the insertion gap 311 is closed by the closing portion 342 of the sliding member 340. Thereby, the mounting shaft portion 360a of the tab 360 is housed in the accommodating space 312, and the tab 360 is held by the tab holding body 330.

另一方面，於日本專利實公平4-32974號公報(專利文獻2)中，亦揭示有一種科實現拉片之裝卸的拉鏈用滑件。該專利文獻2所記載之滑件包括自動停止機構，其係在未進行扣件之開閉操作時，相對於鏈齒排藉由停止爪體使滑件之滑動自動停止。On the other hand, Japanese Patent Publication No. Hei 4-32974 (Patent Document 2) discloses a slider for a slide fastener that realizes attachment and detachment of a handle. The slider described in Patent Document 2 includes an automatic stop mechanism that automatically stops the sliding of the slider with respect to the element row by the stopping claw when the opening and closing operation of the fastener is not performed.

此處，若一面參照圖25及圖26，一面簡單說明專利文獻2之滑件，則該滑件410包含滑件本體420與拉片460，於滑件本體420中，藉由軸支停止爪體470之銷471而固定有拉片保持體430。再者，停止爪體470藉由保持於滑件本體420內之彈簧472而施壓，以使停止爪體470中所設之爪部473突出於上下翼板421、422間之鏈齒導引通路426。Here, the slider of Patent Document 2 will be briefly described with reference to FIGS. 25 and 26, and the slider 410 includes a slider body 420 and a pull tab 460. In the slider body 420, the pawl is stopped by the shaft. The pull tab holder 430 is fixed to the pin 471 of the body 470. Further, the stopping claw body 470 is pressed by the spring 472 held in the slider body 420 so that the claw portion 473 provided in the stopping claw body 470 protrudes from the element guide between the upper and lower flaps 421, 422. Path 426.

拉片保持體430包含：固定端部431，其自上翼板421之前端部豎起；延設部432，其自該固定端部431彎曲而向後方延伸；以及自由端部433，其自該延設部432向上翼板421側彎曲；且於拉片保持體430之自由端部433側之端面與上翼板421之間，形成有能夠使拉片460之安裝軸部460a插通之特定的插通間隙。The tab holding body 430 includes: a fixed end portion 431 that rises from a front end portion of the upper wing plate 421; an extended portion 432 that is bent from the fixed end portion 431 to extend rearward; and a free end portion 433 that The extended portion 432 is bent toward the upper blade 421 side; and between the end surface on the free end portion 433 side of the tab holding body 430 and the upper blade 421, a mounting shaft portion 460a of the pull tab 460 can be inserted. Specific insertion gap.

又，於拉片保持體430之延設部432中的上翼板421側之下端緣，形成有用以形成使拉片460之安裝軸部460a退避的退避空間之退避空間用凹部435、用以形成收容拉片460之安裝軸部460a的收容空間之收容空間用凹部436、以及夾於兩個凹部435、436之間的連續緣部437。Further, in the lower end edge of the upper blade 421 side of the extended portion 432 of the handle holding member 430, a recessed portion 435 for retreating space for forming a retracting space for retracting the mounting shaft portion 460a of the tab 460 is formed for The accommodating space recess 436 for accommodating the accommodating space for accommodating the mounting shaft portion 460a of the tab 460 and the continuous edge portion 437 sandwiched between the two recesses 435 and 436 are formed.

於上翼板421之上表面側，自上翼板421之後端朝向前方形成有滑動導引溝槽425，於該滑動導引溝槽425內收容有沿該滑動導引溝槽425可滑動地配置之滑動構件440、以及對滑動構件440向後方施壓之彈性構件(螺旋彈簧)450。On the upper surface side of the upper wing plate 421, a sliding guiding groove 425 is formed from the rear end of the upper wing plate 421 toward the front side, and the sliding guiding groove 425 is accommodated in the sliding guiding groove 425 to be slidably mounted along the sliding guiding groove 425. The sliding member 440 is disposed, and an elastic member (coil spring) 450 that presses the sliding member 440 rearward.

於滑動構件440中，設有在該滑動構件440移動至施壓方向側之滑動端之狀態時封閉插通間隙之第1封閉部441、以及封閉拉片保持體430之連續緣部437與上翼板421之間的間隙之第2封閉部442，且於第1封閉部441與第2封閉部442之間形成有能夠收容拉片460之安裝軸部460a的凹溝槽443。The sliding member 440 is provided with a first closing portion 441 that closes the insertion gap when the sliding member 440 is moved to the sliding end of the pressing direction side, and a continuous edge portion 437 and the upper portion of the closing tab holding body 430. The second closing portion 442 of the gap between the flaps 421 is formed with a concave groove 443 capable of accommodating the mounting shaft portion 460a of the tab 460 between the first closing portion 441 and the second closing portion 442.

於上述專利文獻2之滑件410中，於組裝滑件本體420後安裝拉片460時，使拉片460之安裝軸部460a自後方抵壓於滑動構件440之第1封閉部441，抵抗彈性構件450之施壓而使滑動構件440向前方滑動。藉此，拉片保持體430之自由端部433與上翼板421之間的插通間隙開口，並且使拉片460之安裝軸部460a一面抵壓於第1封閉部441，一面通過已開口之插通間隙。繼而，將拉片460之安裝軸部460a向上方提拉而使其移動至退避空間(退避空間用凹部435)。藉此，滑動構件440受到彈性構件450施壓而移動至施壓方向側之滑動端為止，因此插通間隙被該滑動構件440之第1封閉部441所封閉。In the slider 410 of the above-mentioned Patent Document 2, when the slider 460 is attached after assembling the slider body 420, the mounting shaft portion 460a of the tab 460 is pressed against the first closing portion 441 of the sliding member 440 from the rear to resist elasticity. The pressing of the member 450 causes the sliding member 440 to slide forward. Thereby, the insertion gap between the free end portion 433 of the tab holding body 430 and the upper blade 421 is opened, and the mounting shaft portion 460a of the tab 460 is pressed against the first closing portion 441, and the opening is opened. The gap is inserted. Then, the attachment shaft portion 460a of the tab 460 is pulled upward and moved to the retraction space (retraction space recess 435). Thereby, since the sliding member 440 is pressed by the elastic member 450 and moved to the sliding end of the pressing direction side, the insertion gap is closed by the first closing portion 441 of the sliding member 440.

其次，使拉片460之安裝軸部460a移動至下方而收容於滑動構件440之凹溝槽443內，進而將該安裝軸部460a抵壓於滑動構件440之第2封閉部442，抵抗彈性構件450之施壓而使滑動構件440向前方滑動。藉此，使拉片保持體430之連續緣部437與上翼板421之間的間隙開口，並使拉片460之安裝軸部460a通過該間隙。Then, the mounting shaft portion 460a of the pull tab 460 is moved downward to be received in the recessed groove 443 of the sliding member 440, and the mounting shaft portion 460a is pressed against the second closing portion 442 of the sliding member 440 to resist the elastic member. The pressing force of 450 causes the sliding member 440 to slide forward. Thereby, the gap between the continuous edge portion 437 of the tab holding body 430 and the upper blade 421 is opened, and the mounting shaft portion 460a of the tab 460 is passed through the gap.

其後，將拉片460之安裝軸部460a向上方提拉，使其自滑動構件440之凹溝槽443內移動至收容空間(收容空間用凹部436)。藉此，成為如下狀態：滑動構件440受到彈性構件450施壓而移動至施壓方向側之滑動端為止，且拉片460保持於拉片保持體430。Thereafter, the attachment shaft portion 460a of the tab 460 is pulled upward to move from the inside of the recessed groove 443 of the slide member 440 to the accommodating space (the accommodating space recess 436). As a result, the sliding member 440 is pressed by the elastic member 450 to move to the sliding end on the pressing direction side, and the tab 460 is held by the tab holding body 430.

如此，只要為專利文獻2之滑件410，則即使於滑件本體420配置有停止爪體470，亦可穩定地進行拉片460之安裝，而且亦可視需要將拉片460自拉片保持體430拆下而容易地進行更換。As described above, as long as the slider 410 of Patent Document 2 is provided, even if the slider body 420 is provided with the stopping claw body 470, the mounting of the tab 460 can be stably performed, and the tab 460 can be self-tensioning the holding body as needed. The 430 is removed and easily replaced.

上述專利文獻1或專利文獻2所記載之滑件310、410中，當可滑動地配置於滑件本體320、420之滑動構件340、440受到彈性構件350、450施壓而位於施壓方向側之滑動端時，於拉片保持體330、430之自由端部333、433與上翼板321、421之間所形成的插通間隙311係被滑動構件340、440之封閉部342、441所封閉。In the sliders 310 and 410 described in Patent Document 1 or Patent Document 2, the sliding members 340 and 440 slidably disposed on the slider bodies 320 and 420 are pressed by the elastic members 350 and 450 to be placed on the pressing direction side. At the sliding end, the insertion gap 311 formed between the free ends 333, 433 of the tab holding members 330, 430 and the upper flaps 321, 421 is closed by the closing portions 342, 441 of the sliding members 340, 440. Closed.

於此情形時，於拉片保持體330、430中之自由端部333、433側之端面333a與滑動構件340、440之封閉部342、441之間通常設有縫隙，以使滑動構件340、440與拉片保持體330、430之自由端部333、433不接觸。其原因在於，當例如使拉片保持體之自由端部側之端面與滑動構件之封閉部彼此接觸而構成滑件時，由於滑件之構成零件中的尺寸精度等問題，滑動構件有可能會鉤住拉片保持體而不移動，或者滑動構件之滑動性有可能會下降。In this case, a gap is generally provided between the end faces 333a on the free end portions 333, 433 side of the tab holding bodies 330, 430 and the closing portions 342, 441 of the sliding members 340, 440, so that the sliding member 340, The 440 is not in contact with the free ends 333, 433 of the tab holders 330, 430. The reason for this is that, for example, when the end surface on the free end side of the tab holding body and the closing portion of the sliding member are in contact with each other to constitute a slider, the sliding member may be caused by problems such as dimensional accuracy in components of the slider. The tab holding body is hooked without moving, or the sliding property of the sliding member may be lowered.

因此，於實際之滑件310、410中，為使滑動構件340、440順暢地滑動而穩定地進行拉片360、460之安裝，於拉片保持體330、430之自由端部333、433側之端面333a與滑動構件340、440之封閉部342、441之間設有某種程度的縫隙。Therefore, in the actual sliders 310 and 410, the sliding members 340 and 440 are smoothly slid to stably mount the tabs 360 and 460, and the free end portions 333 and 433 of the tab holding members 330 and 430 are provided. A certain degree of gap is provided between the end surface 333a and the closing portions 342, 441 of the sliding members 340, 440.

然而，當如上所述於拉片保持體330、430之端面333a與滑動構件340、440之間設有縫隙之情形時，將拉片360、460安裝於滑件310、410時，或將滑件310、410安裝於包等製品而使用時等，存在較薄的布料等異物易於進入至該縫隙之問題(具體而言，例如將滑件安裝於包時，有時西服之袖口等會進入至該滑件中之拉片保持體之端面與滑動構件之間的縫隙)。However, when a gap is provided between the end faces 333a of the tab holding bodies 330, 430 and the sliding members 340, 440 as described above, when the tabs 360, 460 are attached to the sliders 310, 410, or will be slipped When the pieces 310 and 410 are attached to a product such as a bag and used, there is a problem that foreign matter such as a thin cloth easily enters the gap (specifically, for example, when the slider is attached to the bag, the cuff of the suit may enter. a gap between the end surface of the tab holding body and the sliding member in the slider).

又，當如專利文獻1或專利文獻2之滑件310、410般，將滑動構件340、440可滑動地配置於上翼板321、421時，存在如下問題：若例如較厚的布料等碰撞於滑動構件340、440之後方等，則該布料等將推壓滑動構件340、440而使其向前方滑動，從而於拉片保持體330、430之自由端部333、433與滑動構件340、440之間會咬入布料等。Further, when the sliding members 340 and 440 are slidably disposed on the upper blades 321 and 421 as in the sliders 310 and 410 of Patent Document 1 or Patent Document 2, there is a problem in that, for example, a thick cloth or the like collides. After the sliding members 340, 440 or the like, the cloth or the like pushes the sliding members 340, 440 to slide forward, so that the free ends 333, 433 of the tab holding bodies 330, 430 and the sliding member 340, 440 will bite into the fabric.

而且，如上所述，於布料等進入至拉片保持體330、430之自由端部333、433側之端面333a與滑動構件340、440之間的縫隙時，或者於拉片保持體330、430之自由端部333、433與滑動構件340、440之間咬入有布料等時，存在進行拉片360、460之安裝或更換時布料等成為阻礙，又，因布料等而妨礙滑件310、410之操作等的不良情況。此外，當滑件包含利用停止爪體之自動停止機構時，存在進入至上述縫隙之布料等咬入至停止爪體，而妨礙停止爪體之動作的不良情況。Further, as described above, when the cloth or the like enters the gap between the end faces 333a on the free end portions 333, 433 side of the tab holding bodies 330, 430 and the sliding members 340, 440, or the tab holding bodies 330, 430 When a cloth or the like is bitten between the free end portions 333 and 433 and the sliding members 340 and 440, the cloth or the like is prevented from being attached or replaced when the tabs 360 and 460 are attached, and the slider 310 is obstructed by the cloth or the like. Difficulties in the operation of 410. Further, when the slider includes the automatic stop mechanism for stopping the claw body, there is a problem that the cloth or the like that has entered the slit bites into the stop claw body and hinders the operation of stopping the claw body.

藉此，在將拉片之安裝軸部收容於滑動構件之收容溝槽部的狀態下使滑動構件滑動，藉此，可順暢地進行拉片之安裝或拆卸。此外，於本體部之較封閉部更靠施壓方向側的位置豎立設置有輔助封閉部，因此即使於例如較厚的布料等異物碰撞於滑動構件之後側，由該異物推壓滑動構件而使其滑動之情形時，亦可藉由利用輔助封閉部封閉或縮小插通間隙而防止異物進入，且防止於拉片保持體之自由端部與滑動構件之間咬入異物。因此，可防止產生如下不良情況：在進行拉片之安裝或更換時布料等成為阻礙；或滑件之操作受到布料等所妨礙。Thereby, the sliding member is slid in a state in which the attachment shaft portion of the pull-tab is housed in the accommodation groove portion of the slide member, whereby the attachment or detachment of the pull-tab can be smoothly performed. Further, since the auxiliary closing portion is erected at a position closer to the pressing direction side of the closed portion of the main body portion, even if a foreign matter such as a thick cloth collides with the rear side of the sliding member, the sliding member is pressed by the foreign matter. In the case of sliding, it is also possible to prevent foreign matter from entering by closing or narrowing the insertion gap by the auxiliary closing portion, and preventing foreign matter from being bitten between the free end portion of the tab holding body and the sliding member. Therefore, it is possible to prevent the occurrence of a problem that the cloth or the like is hindered when the pull-tab is attached or replaced, or the operation of the slider is hindered by the cloth or the like.

本實施例1之滑動構件40包含：本體部41，其沿滑件本體20之滑動導引溝槽26而滑動；封閉部42，其係突設於該本體部41之前後方向之中央部；導引突條部43，其於本體部41之下表面(背面)側沿前後方向形成為壟狀凸條，且被***至彈簧收容溝槽26b中導引滑動構件40之滑動；以及導引部44，其係配置於本體部41之左右側緣部，並嵌著於滑動導引溝槽26之導引部嵌著溝槽26a。The sliding member 40 of the first embodiment includes: a body portion 41 that slides along the sliding guide groove 26 of the slider body 20; and a closing portion 42 that is protruded from a central portion of the body portion 41 in a front-rear direction; a guide rib portion 43 which is formed as a ridge-like ridge in the front-rear direction on the lower surface (back surface) side of the body portion 41, and is inserted into the spring accommodating groove 26b to guide the sliding of the sliding member 40; The portion 44 is disposed on the left and right side edge portions of the main body portion 41, and is fitted in the guide portion of the sliding guide groove 26 to be fitted with the groove 26a.

於該滑動構件40中，於封閉部42之與拉片保持體30對向的對向面(上表面)42a上，以能夠***形成於拉片保持體30的凸部34之方式，對應於凸部34之位置而設有凹部45。In the sliding member 40, the opposite surface (upper surface) 42a of the closing portion 42 opposed to the tab holding body 30 is inserted into the convex portion 34 formed on the tab holding body 30, corresponding to A recess 45 is provided at the position of the convex portion 34.

凸部34如圖2所示，於拉片保持體30之自由端部33側之端面33a，該凸部34之左右方向之兩側之端面33a係位於較凸部34之前端側之端面33a更上方的位置。又，滑動構件40之對向面42a中之凹部45之底面42a係與凸部34之前端側之端面33a對面。此外，於拉片保持體30之自由端部33中，凸部34之寬度方向(左右方向)之尺寸係設定為小於拉片保持體30中之整體寬度方向之尺寸。As shown in FIG. 2, the convex portion 34 has an end surface 33a on the side of the free end portion 33 of the handle holding body 30, and the end faces 33a on both sides in the left-right direction of the convex portion 34 are located on the end surface 33a of the front end side of the convex portion 34. The upper position. Further, the bottom surface 42a of the concave portion 45 in the opposing surface 42a of the sliding member 40 is opposed to the end surface 33a on the front end side of the convex portion 34. Further, in the free end portion 33 of the handle holding body 30, the dimension in the width direction (left-right direction) of the convex portion 34 is set to be smaller than the overall width direction of the handle holding body 30.

因此，當拉片6之安裝軸部6b尤其形成為圓弧狀時，使安裝軸部6b如後所述抵壓於封閉部42，並抵抗螺旋彈簧5之施壓而推入時，可使拉片6之安裝軸部6b與拉片保持體30之自由端部33難以彼此干擾，從而易於推入拉片6之安裝軸部6b。再者，如此之效果例如於後述之圖6或圖12所示之滑件中亦可同樣地獲得。Therefore, when the mounting shaft portion 6b of the tab 6 is formed in an arc shape in particular, when the mounting shaft portion 6b is pressed against the closing portion 42 as described later and pushed against the pressing force of the coil spring 5, The mounting shaft portion 6b of the tab 6 and the free end portion 33 of the tab holding body 30 are difficult to interfere with each other, so that it is easy to push into the mounting shaft portion 6b of the tab 6. Furthermore, such an effect can be similarly obtained, for example, in the slider shown in FIG. 6 or FIG. 12 which will be described later.

於此情形時，在拉片保持體30之自由端部33側之端面33a及形成於該端面33a的凸部34、與滑動構件40中之封閉部42之上表面42a及形成於該上表面42a的凹部45之間設有縫隙13，以使拉片保持體30與滑動構件40不直接接觸。該縫隙13係藉由拉片保持體30之凸部34及封閉部42之凹部45，於上下方向(滑件高度方向)上鋸齒狀地彎曲，並且在整個左右方向(滑件寬度方向)上形成。In this case, the end surface 33a on the free end portion 33 side of the tab holding body 30, the convex portion 34 formed on the end surface 33a, and the upper surface 42a of the closing portion 42 in the sliding member 40 are formed on the upper surface. A slit 13 is provided between the recesses 45 of 42a so that the tab holding body 30 is not in direct contact with the sliding member 40. The slit 13 is bent in a zigzag manner in the up-and-down direction (slider height direction) by the convex portion 34 of the tab holding body 30 and the concave portion 45 of the closing portion 42, and is in the entire left-right direction (slider width direction). form.

即，將凸部34***於凹部45之狀態係具有凸部34之端面33a之上翼板21側之前端位於較滑動構件40之封閉部42之與拉片保持體30對向之對向面(上表面)42a之前端(左右兩側之上端)更靠滑動構件40之本體部41側(下方側)的位置之狀態。因此，於左右方向上，封閉部42之對向面(上表面)42a之前端(左右兩側之上端)係位於較拉片保持體30中之凸部34之前端面更靠上方側的位置。又，配置於拉片保持體30之左右方向之中央部的凸部34之前端面與封閉部42中之凹部45之底面對向，並且位於較該封閉部42中之左右兩側之對向面(上表面)42a更靠下方側(滑動構件40之本體部41側)的位置。藉此，在滑動構件40與拉片保持體30之自由端部33之間設置鋸齒狀地彎曲之縫隙13。That is, the state in which the convex portion 34 is inserted into the concave portion 45 is such that the end surface 33a of the convex portion 34 is located on the side opposite to the side of the flap 21 of the sliding member 40 and the opposite side of the closing portion 42 of the sliding member 40 from the opposite side of the tab holding body 30. The front end (the upper end of the left and right sides) of the (upper surface) 42a is further in the state of the position of the main body portion 41 side (lower side) of the sliding member 40. Therefore, in the left-right direction, the front end (the upper end of the left and right sides) of the opposing surface (upper surface) 42a of the closing portion 42 is located above the front end surface of the convex portion 34 of the handle holding body 30. Further, the front end surface of the convex portion 34 disposed at the central portion of the tab holding body 30 in the left-right direction faces the bottom surface of the concave portion 45 in the closing portion 42, and is located opposite to the left and right sides of the closing portion 42. The surface (upper surface) 42a is located further on the lower side (the side of the main body portion 41 of the sliding member 40). Thereby, a slit 13 bent in a zigzag manner is provided between the sliding member 40 and the free end portion 33 of the tab holding body 30.

此處，鋸齒狀之縫隙13係形成為具有彎曲成大致90°之階差，但亦可設為例如在左右方向上，於左側及/或右側部分與中央部分具有上下方向之階差，又，亦可設為例如呈至少兩條直線具有特定角度而交叉之大致V字形狀。Here, the zigzag slit 13 is formed to have a stepped thickness of approximately 90°, but may be, for example, in the left-right direction, with a stepwise difference between the left side and/or the right side portion and the central portion, and For example, it may be set to have a substantially V shape in which at least two straight lines have a specific angle and intersect.

本實施例1之拉片6包含能夠用手指捏住之平板狀的拉片本體部6a、及與該拉片本體部6a之一端形成為一體之圓弧狀的安裝軸部6b。The pull tab 6 of the first embodiment includes a flat plate-like main body portion 6a that can be pinched by fingers, and an arc-shaped mounting shaft portion 6b that is integrally formed with one end of the pull-tab main body portion 6a.

其次，對組裝本實施例1之滑件10的順序進行說明。Next, the procedure for assembling the slider 10 of the first embodiment will be described.

首先，進行將滑動構件40與螺旋彈簧5組裝於滑件本體20之操作。具體而言，在形成於滑件本體20之上翼板21的彈簧收容溝槽26b中***螺旋彈簧5，繼而，使滑動構件40之前端面33a抵接於螺旋彈簧5之後端，一面使該螺旋彈簧5壓縮，一面將滑動構件40***至滑動導引溝槽26。First, an operation of assembling the sliding member 40 and the coil spring 5 to the slider body 20 is performed. Specifically, the coil spring 5 is inserted into the spring receiving groove 26b formed in the flap 21 of the slider body 20, and then the front end surface 33a of the sliding member 40 is abutted against the rear end of the coil spring 5, and the spiral is made The spring 5 is compressed to insert the sliding member 40 into the sliding guide groove 26 on one side.

將滑動構件40***至滑動導引溝槽26時，使滑動構件40之導引突條部43嵌入至上翼板21之彈簧收容溝槽26b，並且使滑動構件40之導引部44嵌著於上翼板21之導引部嵌著溝槽26a。然後，將滑動構件40***至滑動導引溝槽26後，將豎立設置於上翼板21之後端部的卡止片27向彼此接近之方向壓彎並加以緊固，藉此將滑動構件40以受到螺旋彈簧5施壓之狀態可滑動地安裝於上翼板21。When the sliding member 40 is inserted into the sliding guide groove 26, the guiding protrusion portion 43 of the sliding member 40 is fitted into the spring receiving groove 26b of the upper blade 21, and the guiding portion 44 of the sliding member 40 is embedded in The guide portion of the upper wing 21 is fitted with a groove 26a. Then, after the sliding member 40 is inserted into the sliding guide groove 26, the locking pieces 27 which are erected at the rear end portions of the upper blade 21 are bent and fastened in the direction in which they approach each other, whereby the sliding member 40 is pressed. The upper blade 21 is slidably attached in a state of being pressed by the coil spring 5.

此時，被緊固之卡止片27係作為滑動構件40之擋止部而發揮作用，因此抵接於卡止片27之滑動構件40之位置成為該滑動構件40之施壓方向側之滑動端，當滑動構件40位於該施壓方向側之滑動端時，藉由滑動構件40之封閉部42，形成於拉片保持體30之自由端部33與上翼板21之間的間隙(插通間隙)12被封閉(或縮小)。另一方面，與滑動構件40之施壓方向為相反側之滑動端，成為滑動構件40之封閉部42抵接於上翼板21之被滑動導引溝槽26覆蓋之部位的位置。At this time, since the fastened locking piece 27 functions as a stopper of the sliding member 40, the position of the sliding member 40 that abuts against the locking piece 27 becomes the sliding side of the sliding member 40 in the pressing direction side. At the end, when the sliding member 40 is located at the sliding end of the pressing direction side, the gap between the free end portion 33 of the tab holding body 30 and the upper flap 21 is formed by the closing portion 42 of the sliding member 40. The through gap) 12 is closed (or reduced). On the other hand, the sliding end opposite to the pressing direction of the sliding member 40 is a position at which the closing portion 42 of the sliding member 40 abuts on the portion of the upper blade 21 covered by the sliding guide groove 26.

再者，本實施例1之滑件10係構成為自側面側觀察該滑件10時，當滑動構件40受到螺旋彈簧5施壓而位於施壓方向側之滑動端時，拉片保持體30之自由端部33延伸出至較位於施壓方向側之滑動端的滑動構件40之封閉部42更後端側(參照圖3)。Further, the slider 10 of the first embodiment is configured such that when the slider 10 is viewed from the side surface side, when the sliding member 40 is pressed by the coil spring 5 and is located at the sliding end of the pressing direction side, the tab holding body 30 is formed. The free end portion 33 extends to the rear end side of the closing portion 42 of the sliding member 40 which is located at the sliding end on the pressing direction side (refer to FIG. 3).

藉此，於較滑動構件40之封閉部42更後方側，在拉片保持體30之自由端部33與上翼板21之間形成特定的間隙14。藉由設有該間隙14，如後所述，在為使滑動構件40向前方滑動而將拉片6之安裝軸部6b抵壓於滑動構件40之封閉部42時，可藉由將拉片6之安裝軸部6b***至該間隙14，而容易地定位該安裝軸部6b。因此，可使安裝軸部6b確實地抵壓於滑動構件40之封閉部42，從而使滑動構件40容易地向前方滑動。Thereby, a specific gap 14 is formed between the free end portion 33 of the tab holding body 30 and the upper blade 21 on the rear side of the closing portion 42 of the sliding member 40. By providing the gap 14, as will be described later, when the mounting shaft portion 6b of the tab 6 is pressed against the closing portion 42 of the sliding member 40 in order to slide the sliding member 40 forward, the tab can be pulled by The mounting shaft portion 6b of 6 is inserted into the gap 14, and the mounting shaft portion 6b is easily positioned. Therefore, the mounting shaft portion 6b can be surely pressed against the closing portion 42 of the sliding member 40, so that the sliding member 40 can easily slide forward.

此外，本實施例1之滑件10中，為使滑動構件40與拉片保持體30之自由端部33不接觸，而於兩者之間形成有縫隙13。與此同時，當滑動構件40位於施壓方向側之滑動端時，構成為將拉片保持體30之自由端部33側之端面33a所形成的凸部34***至滑動構件40之封閉部42之上表面42a所形成的凹部45。此處，所謂將拉片保持體30之凸部34***至滑動構件40之凹部45，係指凸部34之前端部進入至較形成封閉部42之凹部45的上表面42a更靠凹部45之底面側的位置。Further, in the slider 10 of the first embodiment, in order to prevent the sliding member 40 from coming into contact with the free end portion 33 of the handle holding body 30, a slit 13 is formed therebetween. At the same time, when the sliding member 40 is located at the sliding end of the pressing direction side, the convex portion 34 formed by the end surface 33a on the free end portion 33 side of the tab holding body 30 is inserted into the closing portion 42 of the sliding member 40. The recess 45 formed by the upper surface 42a. Here, the insertion of the convex portion 34 of the handle holding body 30 into the concave portion 45 of the sliding member 40 means that the front end portion of the convex portion 34 enters the concave portion 45 of the upper surface 42a of the concave portion 45 which forms the closed portion 42. The position on the bottom side.

藉由如上所述於滑動構件40與拉片保持體30之自由端部33之間形成縫隙13，可在使滑動構件40相對於上翼板21滑動時，使滑動構件40不與拉片保持體30之自由端部33接觸而順暢地滑動。因此，在使滑動構件40滑動而進行拉片6之安裝或拆卸時，可順暢地進行該安裝操作或拆卸操作。By forming the slit 13 between the sliding member 40 and the free end portion 33 of the tab holding body 30 as described above, the sliding member 40 can be held without the tab when the sliding member 40 is slid relative to the upper flap 21. The free end portion 33 of the body 30 contacts and smoothly slides. Therefore, when the sliding member 40 is slid to perform attachment or detachment of the tab 6, the mounting operation or the detaching operation can be smoothly performed.

又，在滑動構件40位於施壓方向側之滑動端時，將拉片保持體30之凸部34***至滑動構件40之凹部45，藉此可使滑動構件40與拉片保持體30之自由端部33之間所形成的縫隙13於上下方向(滑件高度方向)上鋸齒狀地彎曲。藉此，可使得較薄的布料等異物難以進入至該縫隙13。Further, when the sliding member 40 is located at the sliding end of the pressing direction side, the convex portion 34 of the tab holding body 30 is inserted into the concave portion 45 of the sliding member 40, whereby the sliding member 40 and the tab holding body 30 can be freely opened. The slit 13 formed between the end portions 33 is curved in a zigzag manner in the up and down direction (slider height direction). Thereby, foreign matter such as a thin cloth can be made difficult to enter the slit 13.

如上所述進行將滑動構件40與螺旋彈簧5組裝於滑件本體20之操作後，進行將拉片6安裝於拉片保持體30之操作。具體而言，如圖3所示，將拉片6之安裝軸部6b自後方側***至拉片保持體30之自由端部33側之端面33a與上翼板21之間所形成的特定的間隙14，並抵壓於滑動構件40之封閉部42，進而藉由該安裝軸部6b將滑動構件40之封閉部42向前方推入。After the operation of assembling the sliding member 40 and the coil spring 5 to the slider body 20 as described above, the operation of attaching the tab 6 to the tab holding body 30 is performed. Specifically, as shown in FIG. 3, the mounting shaft portion 6b of the pull tab 6 is inserted from the rear side to a specific shape formed between the end surface 33a of the free end portion 33 side of the tab holding body 30 and the upper flap 21. The gap 14 is pressed against the closing portion 42 of the sliding member 40, and the closing portion 42 of the sliding member 40 is pushed forward by the mounting shaft portion 6b.

藉此，如圖4所示，滑動構件40抵抗螺旋彈簧5之施壓而沿上翼板21之滑動導引溝槽26向前方滑動，進而藉由滑動構件40向前方滑動，由滑動構件40之封閉部42所封閉之插通間隙12開口。因此，可經由已開口之插通間隙12，使拉片6之安裝軸部6b移動至收容空間11內。Thereby, as shown in FIG. 4, the sliding member 40 slides forward along the sliding guide groove 26 of the upper blade 21 against the pressing force of the coil spring 5, and is slid forward by the sliding member 40, by the sliding member 40. The insertion gap 12 closed by the closing portion 42 is open. Therefore, the mounting shaft portion 6b of the pull tab 6 can be moved into the accommodating space 11 via the inserted insertion gap 12.

然後，若於拉片6之安裝軸部6b移動至收容空間11內之後，將該安裝軸部6b向上方提拉，解除利用安裝軸部6b所進行之滑動構件40之推壓，則向前方推入之滑動構件40將受到螺旋彈簧5施壓而移動至施壓方向側之滑動端，從而封閉拉片保持體30之自由端部33與上翼板21之間的插通間隙12。藉此，可將拉片6之安裝軸部6b收容於收容空間11內，從而獲得將拉片6保持於拉片保持體30的本實施例1之滑件10。Then, after the attachment shaft portion 6b of the tab 6 is moved into the accommodating space 11, the attachment shaft portion 6b is pulled upward, and the pressing of the slide member 40 by the attachment shaft portion 6b is released, and the front is pushed forward. The pushed sliding member 40 is pressed by the coil spring 5 to the sliding end on the pressing direction side, thereby closing the insertion gap 12 between the free end portion 33 of the tab holding body 30 and the upper flap 21. Thereby, the attachment shaft portion 6b of the tab 6 can be housed in the accommodating space 11, and the slider 10 of the first embodiment in which the tab 6 is held by the tab holding body 30 can be obtained.

再者，於拆卸滑件10之拉片保持體30所保持之拉片6之情形時，藉由用手指等將滑動構件40向前方推壓，使其抵抗螺旋彈簧5之施壓而前進。藉此，拉片保持體30之自由端部33與上翼板21之間的插通間隙12開口，因此經由該插通間隙12自收容空間11拔出拉片6之安裝軸部6b，可容易地拆卸拉片6。Further, when the tab 6 held by the tab holding body 30 of the slider 10 is detached, the sliding member 40 is pushed forward by a finger or the like to advance against the pressing force of the coil spring 5. Thereby, the insertion gap 12 between the free end portion 33 of the tab holding body 30 and the upper blade 21 is opened, so that the mounting shaft portion 6b of the pull tab 6 is pulled out from the housing space 11 via the insertion gap 12, The tab 6 is easily detached.

如上所述，本實施例1之滑件10係構成為藉由使滑動構件40可滑動地配置於上翼板21，而使拉片6可對於滑件本體20進行裝卸。As described above, the slider 10 of the first embodiment is configured such that the slider 6 can be detachably attached to the slider body 20 by slidably disposing the sliding member 40 on the upper blade 21.

此外，於該滑件10中，於滑動構件40與拉片保持體30之自由端部33之間具有縫隙13，並且設置於拉片保持體30之端面33a的凸部34與設置於滑動構件40的凹部45係沿滑動構件40之滑動方向而形成。因此，在使滑動構件40相對於上翼板21滑動時，能夠使該滑動構件40不與拉片保持體30之自由端部33接觸而順暢地滑動，因此可穩定地進行拉片6之安裝或拆卸。Further, in the slider 10, a slit 13 is provided between the sliding member 40 and the free end portion 33 of the tab holding body 30, and the convex portion 34 provided on the end surface 33a of the tab holding body 30 and the sliding member are provided. The recess 45 of the 40 is formed along the sliding direction of the sliding member 40. Therefore, when the sliding member 40 is slid with respect to the upper blade 21, the sliding member 40 can be smoothly slid without coming into contact with the free end portion 33 of the tab holding body 30, so that the mounting of the tab 6 can be stably performed. Or disassemble.

而且，滑動構件40與拉片保持體30之自由端部33之間所形成的縫隙13係藉由設置於拉片保持體30之端面33a的凸部34與設置於滑動構件40的凹部45，於上下方向上鋸齒狀地彎曲，因此可防止較薄的布料等異物進入至該縫隙13。因此，可防止產生先前之滑件10所產生之不良情況，具體而言為如下不良情況，即，進入至縫隙13之異物在進行拉片6之安裝或更換時成為阻礙，或滑件10之操作受到進入至縫隙13之異物所妨礙。Further, the slit 13 formed between the sliding member 40 and the free end portion 33 of the tab holding body 30 is provided by the convex portion 34 provided on the end surface 33a of the tab holding body 30 and the concave portion 45 provided in the sliding member 40. Since it is bent in a zigzag manner in the up and down direction, foreign matter such as a thin cloth can be prevented from entering the slit 13. Therefore, it is possible to prevent the occurrence of the malfunction of the previous slider 10, specifically, the problem that the foreign matter entering the slit 13 becomes obstructed when the tab 6 is mounted or replaced, or the slider 10 The operation is hindered by the foreign matter entering the slit 13.

再者，在上述實施例1之滑件10中，於拉片保持體30之自由端部33側之端面33a設置凸部34，並且於滑動構件40之封閉部42之上表面設置能夠***拉片保持體30之凸部34的凹部45，藉此防止異物進入至拉片保持體30之自由端部33與滑動構件40之間所形成的縫隙13。Further, in the slider 10 of the above-described first embodiment, the convex portion 34 is provided on the end surface 33a of the free end portion 33 side of the handle holding member 30, and the upper surface of the closing portion 42 of the sliding member 40 is provided to be insertable and pullable. The recess 45 of the convex portion 34 of the sheet holding body 30, thereby preventing foreign matter from entering the slit 13 formed between the free end portion 33 of the tab holding body 30 and the sliding member 40.

但是，本發明並不限定於上述實施例1之形態或後述之實施例2~實施例4之形態，例如，如圖5所示之滑件之變形例般，藉由在拉片保持體30之自由端部33側之端面33a設置凹部35，並且在滑動構件40之封閉部42之上表面42a設置能夠***至拉片保持體30之凹部35的凸部46，亦可防止異物進入至拉片保持體30之自由端部33與滑動構件40之間所形成的縫隙13。However, the present invention is not limited to the form of the above-described first embodiment or the embodiments 2 to 4 which will be described later. For example, as shown in the modified example of the slider shown in FIG. 5, the handle holding body 30 is provided. The end surface 33a on the free end portion 33 side is provided with the concave portion 35, and the convex portion 46 which can be inserted into the concave portion 35 of the handle holding body 30 is provided on the upper surface 42a of the closing portion 42 of the sliding member 40, and the foreign matter can be prevented from entering and pulling. A slit 13 formed between the free end portion 33 of the sheet holding body 30 and the sliding member 40.

又，亦可於拉片保持體30之自由端部33側之端面33a，並非設置如上述實施例1般朝向滑件長度方向之橫截面呈大致矩形狀的凸部34，而如圖6表示之滑件之另一變形例般，設置朝向滑件長度方向之橫截面呈大致三角形狀的凸部34a，並且將對應於凸部34a之剖面形狀以能夠***該凸部34a的凹部45a凹設於滑動構件40之封閉部42之上表面42a。該凸部34a係自拉片保持體30之自由端部33之寬度方向(左右方向)整個面延設，呈隨著朝向下方寬度方向(左右方向)之壁厚逐漸減小之形狀。Further, the end surface 33a on the free end portion 33 side of the tab holding body 30 may not be provided with the convex portion 34 having a substantially rectangular cross section in the longitudinal direction of the slider as in the first embodiment, but as shown in FIG. In another modification of the slider, a convex portion 34a having a substantially triangular cross section in the longitudinal direction of the slider is provided, and a cross-sectional shape corresponding to the convex portion 34a is recessed in a concave portion 45a into which the convex portion 34a can be inserted. On the upper surface 42a of the closing portion 42 of the sliding member 40. The convex portion 34a is extended from the entire width direction (left-right direction) of the free end portion 33 of the handle holding body 30, and has a shape that gradually decreases in thickness toward the lower width direction (left-right direction).

再者，如圖7所示之滑件之進而另一變形例般，當於拉片保持體30之自由端部33側設有例如朝向滑件長度方向之橫截面呈大致三角形狀的凸部34a(與圖6相同之凸部34a)時，滑動構件40之封閉部42之上表面所設置之凹部45只要可***該凸部34a，則亦可具有與凸部34a之剖面形狀不對應之大致矩形狀的空間。Further, as another modification of the slider shown in Fig. 7, a convex portion having a substantially triangular cross section in the longitudinal direction of the slider, for example, is provided on the free end portion 33 side of the tab holding body 30. In the case of 34a (the convex portion 34a similar to that of FIG. 6), the concave portion 45 provided on the upper surface of the closing portion 42 of the sliding member 40 may have a shape corresponding to the cross-sectional shape of the convex portion 34a as long as it can be inserted into the convex portion 34a. A generally rectangular space.

又，在上述實施例1及變形例中，於拉片保持體30之自由端部33側之端面33a與滑動構件40之封閉部42之上表面42a，凸部與凹部係彼此對應地形成於滑件寬度方向之大致中央部。但是，於本發明中，只要可防止異物進入至拉片保持體30之自由端部33與滑動構件40之間所形成的縫隙13，則可對應於自滑件寬度方向之大致中央部移位後之位置形成凸部與凹部。Further, in the first embodiment and the modified example, the end surface 33a on the free end portion 33 side of the handle holding member 30 and the upper surface 42a of the closing portion 42 of the sliding member 40 are formed corresponding to each other in the convex portion and the concave portion. The center of the slider in the width direction. However, in the present invention, as long as foreign matter can be prevented from entering the slit 13 formed between the free end portion 33 of the tab holding body 30 and the sliding member 40, it can be displaced corresponding to the substantially central portion from the width direction of the slider. The rear position forms a convex portion and a concave portion.

例如，亦可如圖8所示之滑件之進而另一變形例般，自滑件之後端側觀察時，於拉片保持體30之自由端部33側之端面33a，使剖面呈大致矩形狀之凸部34b形成於自由端部33之偏左側，並且於滑動構件40之封閉部42之上表面42a，使能夠***拉片保持體30之凸部34b的凹部45b形成於封閉部42之偏左側。For example, as shown in still another modification of the slider shown in Fig. 8, when viewed from the rear end side of the slider, the end surface 33a on the free end portion 33 side of the tab holding body 30 has a substantially rectangular cross section. The convex portion 34b is formed on the left side of the free end portion 33, and on the upper surface 42a of the closing portion 42 of the sliding member 40, the concave portion 45b into which the convex portion 34b of the handle holding body 30 can be inserted is formed in the closing portion 42 To the left.

再者，於該圖8所示之變形例之情形時，藉由改變凸部與凹部之觀察方式，亦可理解為例如於拉片保持體30之自由端部33之偏右側形成有凹部，且於滑動構件40之封閉部42之偏右側形成有能夠***至拉片保持體30之凹部的凸部。Further, in the case of the modification shown in FIG. 8, by changing the manner in which the convex portion and the concave portion are observed, it can be understood that, for example, a concave portion is formed on the right side of the free end portion 33 of the handle holding body 30, Further, a convex portion that can be inserted into the concave portion of the handle holding body 30 is formed on the right side of the closing portion 42 of the sliding member 40.

於上述之任一變形例中，均為拉片保持體之自由端部側之端面中的上翼板側之前端(下端)構成為位於較滑動構件之封閉部之與拉片保持體對向的對向面中之自由端部側之前端(上端)更靠滑動構件之本體部側(下方側)的位置，且於拉片保持體之自由端部與滑動構件之間設置鋸齒狀的縫隙方面共通。In any of the above-described modifications, the upper end side (lower end) of the upper end side of the end surface on the free end side of the tab holding body is configured to be located opposite the tab holding body of the closing portion of the sliding member. The free end side front end (upper end) of the opposite side faces the position of the main body side (lower side) of the sliding member, and a zigzag gap is provided between the free end portion of the tab holding body and the sliding member Common in all aspects.

The left and right side edges of the lower blade 122 are extended; and a Y-shaped element guide passage 125 is formed between the upper and lower blades 121 and 122. Further, the slider body 120 is provided with a sliding guiding hole 126 that penetrates from the upper surface of the upper blade 121 to the lower surface of the lower blade 122 via the inside of the guiding post 123, and is disposed in the sliding guiding hole 126. The lower wing plate 122 side is formed with a fastening groove 128 that can engage the brake pad 127 that supports one end of the coil spring 105.

與該滑件本體120形成為一體之拉片保持體130包含：固定端部131，其自上翼板121之後端部(較滑件110之前後方向中央更偏靠後方)豎起；延設部132，其自該固定端部131彎曲並向後方延伸；以及自由端部133，其自該延設部132向上翼板121側彎曲。於該拉片保持體130與上翼板121之上表面之間，形成有收容拉片之安裝軸部的收容空間111，並且於拉片保持體130之自由端部133側之端面133a(與上翼板121相對之面)與上翼板121之上表面之間，形成有可插通拉片之安裝軸部的插通間隙112。此外，於拉片保持體130中之自由端部133側之端面133a，沿前後方向凹設有凹部135。The handle holding body 130 integrally formed with the slider body 120 includes: a fixed end portion 131 which is erected from the rear end portion of the upper wing plate 121 (more rearward than the center of the slider 110 in the front and rear direction); The portion 132 is bent from the fixed end portion 131 and extends rearward, and the free end portion 133 is bent from the extended portion 132 toward the side of the flap 121. Between the handle holding body 130 and the upper surface of the upper blade 121, a receiving space 111 for accommodating the mounting shaft portion of the tab is formed, and an end surface 133a on the free end portion 133 side of the tab holding body 130 (and An insertion gap 112 through which the mounting shaft portion of the pull tab can be inserted is formed between the opposing surface of the upper blade 121 and the upper surface of the upper blade 121. Further, a concave portion 135 is recessed in the front-rear direction on the end surface 133a on the free end portion 133 side of the handle holding body 130.

本實施例2之滑動構件140包含：本體部141，其可滑動地嵌著於滑件本體120之滑動導引孔126；封閉部142，其自該本體部141向上方延設；以及凸部146，其自封閉部142向上方連續地形成，可***至拉片保持體130之凹部135。於此情形時，滑動構件140之本體部141、封閉部142及凸部146係滑件寬度方向之尺寸均具有相同大小而形成為一體，並且於封閉部142及凸部146之後部，形成有朝向上方使滑件長度方向之尺寸逐漸減小之傾斜面143。The sliding member 140 of the second embodiment includes a body portion 141 slidably embedded in the sliding guide hole 126 of the slider body 120, a closing portion 142 extending upward from the body portion 141, and a convex portion 146. It is continuously formed upward from the closing portion 142 and can be inserted into the recess 135 of the tab holding body 130. In this case, the main body portion 141, the closing portion 142, and the convex portion 146 of the sliding member 140 are integrally formed to have the same size in the width direction of the slider, and are formed at the rear portion of the closing portion 142 and the convex portion 146. An inclined surface 143 that gradually decreases in size in the longitudinal direction of the slider toward the upper side.

此外，於本體部141之下端面141a形成有可***螺旋彈簧105之另一端部的***孔144。再者，於本實施例2中，滑動構件140中之施壓方向側之滑動端係藉由未圖示之定位機構，設定於如在配置於該滑動構件140之凸部146與配置於拉片保持體130之凹部135之間形成縫隙113般之特定位置。Further, an insertion hole 144 into which the other end portion of the coil spring 105 can be inserted is formed on the lower end surface 141a of the body portion 141. Further, in the second embodiment, the sliding end of the sliding member 140 on the pressing direction side is set to be disposed on the convex portion 146 of the sliding member 140 by a positioning mechanism (not shown). The recess 135 of the sheet holding body 130 forms a specific position like the slit 113.

其次，對組裝本實施例2之滑件110的順序進行說明。Next, the procedure for assembling the slider 110 of the second embodiment will be described.

首先，為將滑動構件140安裝於滑件本體120，將滑動構件140自下方側***至形成於滑件本體120之滑動導引孔126，繼而，將螺旋彈簧105自下方***至該滑動導引孔126，並且將該螺旋彈簧105之另一端部***至滑動構件140之***孔144。First, in order to attach the sliding member 140 to the slider body 120, the sliding member 140 is inserted from the lower side into the sliding guide hole 126 formed in the slider body 120, and then the coil spring 105 is inserted from below to the sliding guide The hole 126, and the other end portion of the coil spring 105 is inserted into the insertion hole 144 of the sliding member 140.

其次，一面使制動片127抵接於螺旋彈簧105之一端，利用制動片127使該螺旋彈簧105壓縮，一面使該制動片127扣合於滑件本體120之扣合溝槽128。藉此，滑動構件140以被螺旋彈簧105向上方施壓之狀態，沿上下方向可滑動地安裝於滑件本體120。Next, the brake pad 127 abuts against one end of the coil spring 105, and the coil spring 105 is compressed by the brake pad 127, and the brake pad 127 is engaged with the engaging groove 128 of the slider body 120. Thereby, the sliding member 140 is slidably attached to the slider body 120 in the up-and-down direction in a state where the coil spring 105 is pressed upward.

此時，滑動構件140被螺旋彈簧105向上方施壓，因此如圖9及圖10所示，成為如下狀態：滑動構件140之凸部146被***至拉片保持體130之凹部135內，並且拉片保持體130之自由端部133與上翼板121之間所形成的插通間隙112被滑動構件140之封閉部142所封閉。At this time, since the sliding member 140 is pressed upward by the coil spring 105, as shown in FIGS. 9 and 10, the convex portion 146 of the sliding member 140 is inserted into the concave portion 135 of the handle holding body 130, and The insertion gap 112 formed between the free end portion 133 of the tab holding body 130 and the upper blade 121 is closed by the closing portion 142 of the sliding member 140.

滑動構件140之凸部146如實施例1所示，並非為面之一部分突出者，而係形成為滑動構件140之左右方向之整個面(與本體部141相同之寬度)之凸部，該凸部146隨著朝向上方，前後方向之壁厚逐漸減小。於該例中，凸部146亦係封閉部142之一部分。As shown in the first embodiment, the convex portion 146 of the sliding member 140 is not a part of the surface, but is formed as a convex portion of the entire surface of the sliding member 140 in the left-right direction (the same width as the main body portion 141). As the portion 146 faces upward, the wall thickness in the front-rear direction gradually decreases. In this example, the projection 146 is also a portion of the closure portion 142.

於本說明書之實施例中，所謂凸部係形容***至凹部之部分者，並不限定於自平面上僅突出一部分者。In the embodiment of the present specification, the portion in which the convex portion is described as being inserted into the concave portion is not limited to a portion that protrudes only from the plane.

其後，為將未圖示之拉片安裝於組裝有滑動構件140與螺旋彈簧105之滑件本體120，將拉片之安裝軸部自後方側***至拉片保持體130之自由端部133側之端面133a與上翼板121之間所形成的插通間隙112，使該安裝軸部抵接於滑動構件140之封閉部142。Thereafter, a pull tab (not shown) is attached to the slider body 120 in which the slide member 140 and the coil spring 105 are assembled, and the mounting shaft portion of the pull tab is inserted from the rear side to the free end portion 133 of the tab holding body 130. The insertion gap 112 formed between the side end surface 133a and the upper blade 121 causes the mounting shaft portion to abut against the closing portion 142 of the sliding member 140.

進而，將該安裝軸部向前方推入，藉此介以封閉部142及形成於凸部146之傾斜面143，使滑動構件140抵抗螺旋彈簧105之施壓而向下方滑動。其結果為，由滑動構件140之封閉部142所封閉之插通間隙112開口，因此，經由該已開口之插通間隙112使拉片之安裝軸部移動至收容空間111內，可將拉片安裝於拉片保持體130。Further, the mounting shaft portion is pushed forward, whereby the sliding member 140 is slid downward by the pressing force of the coil spring 105 via the closing portion 142 and the inclined surface 143 formed on the convex portion 146. As a result, the insertion gap 112 closed by the closing portion 142 of the sliding member 140 is opened. Therefore, the mounting shaft portion of the pull tab is moved into the receiving space 111 via the opened insertion gap 112, and the pull tab can be pulled. Mounted to the pull tab holder 130.

只要為上述本實施例2之滑件110，便可藉由使滑動構件140相對於滑件本體120沿上下方向滑動，而穩定地進行拉片之安裝或拆卸。而且，由於滑動構件140與拉片保持體130之自由端部133之間所形成的縫隙113係沿上下方向鋸齒狀地彎曲，故可防止較薄的布料等異物進入至該縫隙113，因此可獲得與上述實施例1之滑件110相同的效果。As long as the slider 110 of the second embodiment described above is slidable in the vertical direction with respect to the slider body 120, the slider can be stably attached or detached. Further, since the slit 113 formed between the sliding member 140 and the free end portion 133 of the tab holding body 130 is bent in a zigzag manner in the vertical direction, foreign matter such as a thin cloth can be prevented from entering the slit 113, so that The same effect as the slider 110 of the above-described Embodiment 1 is obtained.

圖11係本實施例3之滑件之分解立體圖，圖12係表示該滑件中形成於拉片保持體之自由端部側的凸部與形成於滑動構件之封閉部及輔助封閉部的凹部之關係的剖面圖。又，圖13~圖15係說明將拉片安裝於滑件本體時之操作的說明圖。Figure 11 is an exploded perspective view of the slider of the third embodiment, and Figure 12 is a view showing a convex portion of the slider formed on the free end side of the tab holding body and a recess formed in the closing portion and the auxiliary closing portion of the sliding member. A cross-sectional view of the relationship. 13 to 15 are explanatory views for explaining an operation when the pull tab is attached to the slider body.

再者，於本實施例3之滑件中，除形成於拉片保持體之自由端部側的凸部之形態與滑動構件之形態以外，均構成為與上述實施例1之滑件基本相同。因此，於本實施例3之滑件及後述之變形例中，對於具有與上述實施例1中所說明之構件或部位相同之構成者，係藉由使用相同的符號表示來省略其說明。Further, in the slider of the third embodiment, the shape of the convex portion formed on the free end side of the tab holding body and the form of the sliding member are substantially the same as those of the slider of the first embodiment. . Therefore, in the slider of the third embodiment and the modifications described later, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

本實施例3之滑件50包括：滑件本體20；拉片保持體60，其係懸臂狀地固定於滑件本體20；滑動構件70，其係沿前後方向可滑動地配置於滑件本體20；螺旋彈簧5，其對滑動構件70向後方施壓；以及拉片6，其係保持於拉片保持體60。The slider 50 of the third embodiment includes: a slider body 20; a tab holding body 60 fixed to the slider body 20 in a cantilever manner; and a sliding member 70 slidably disposed in the slider body in the front-rear direction 20; a coil spring 5 which presses the sliding member 70 rearward; and a pull tab 6 which is held by the tab holding body 60.

於本實施例3之拉片保持體60中之自由端部63側之端面63a，沿滑動構件70之滑動方向形成有朝向前後方向之橫截面呈在下側為大致三角形狀的凸部64，於該凸部64之下端部與上翼板21之上表面之間，形成可使拉片6之安裝軸部6b插通的插通間隙12。The end surface 63a on the side of the free end portion 63 of the handle holding member 60 of the third embodiment is formed with a convex portion 64 having a substantially triangular shape on the lower side in a cross section in the front-rear direction along the sliding direction of the sliding member 70. An insertion gap 12 through which the mounting shaft portion 6b of the tab 6 can be inserted is formed between the lower end portion of the convex portion 64 and the upper surface of the upper blade 21.

本實施例3之滑動構件70包含：本體部71，其沿形成於上翼板21的滑動導引溝槽26滑動；封閉部72，其係突設於該本體部71之前後方向之中央部；輔助封閉部77，其係突設於本體部71之後端部；導引突條部73，其於本體部71之下表面(背面)側形成為壟狀凸條；以及導引部74，其係配置於本體部71之左右側緣部。又，於滑動構件70之封閉部72與輔助封閉部77之間，形成有可收容拉片6之安裝軸部6b的收容溝槽部78。The sliding member 70 of the third embodiment includes a body portion 71 that slides along a sliding guide groove 26 formed on the upper blade 21, and a closing portion 72 that is provided at a central portion of the body portion 71 in the front and rear directions. The auxiliary closing portion 77 is provided at the rear end portion of the main body portion 71; the guiding protrusion portion 73 is formed as a ridge-like ridge on the lower surface (back surface) side of the main body portion 71; and a guiding portion 74, This is disposed on the left and right side edge portions of the main body portion 71. Further, between the closing portion 72 of the sliding member 70 and the auxiliary closing portion 77, a receiving groove portion 78 for accommodating the mounting shaft portion 6b of the tab 6 is formed.

於該滑動構件70中，於封閉部72之與拉片保持體60對向的對向面(上表面)72a，以能夠***形成於拉片保持體60的凸部64之方式，對應於凸部64之位置形成有凹部75。於此情形時，在拉片保持體60之自由端部63側之端面63a及形成於該端面63a的凸部64、與滑動構件70中之封閉部72之上表面72a及形成於該上表面72a的凹部75之間，在整個左右方向上形成有沿上下方向彎曲之縫隙13。In the sliding member 70, the opposing surface (upper surface) 72a of the closing portion 72 opposed to the handle holding body 60 is inserted into the convex portion 64 formed on the tab holding body 60, corresponding to the convex portion. A recess 75 is formed at the position of the portion 64. In this case, the end surface 63a on the free end portion 63 side of the tab holding body 60, the convex portion 64 formed on the end surface 63a, and the upper surface 72a of the closing portion 72 in the sliding member 70 are formed on the upper surface. Between the recesses 75 of 72a, slits 13 which are curved in the vertical direction are formed in the entire left-right direction.

又，於輔助封閉部77之上表面77a亦形成有與形成於封閉部72之凹部75相同的凹部77b，以防止滑動構件70向前方滑動時輔助封閉部77與拉片保持體60之自由端部63接觸。此外，該輔助封閉部77係以如下方式形成：將滑動構件70安裝於滑件本體20之上翼板21時，自上翼板21算起之輔助封閉部77的突出高度低於自上翼板21算起之封閉部72的突出高度。Further, the upper surface 77a of the auxiliary closing portion 77 is also formed with the same concave portion 77b as the concave portion 75 formed in the closing portion 72 to prevent the free end of the auxiliary closing portion 77 and the tab holding body 60 when the sliding member 70 is slid forward. The part 63 is in contact. Further, the auxiliary closing portion 77 is formed in such a manner that when the sliding member 70 is attached to the upper wing 21 of the slider body 20, the protruding height of the auxiliary closing portion 77 from the upper wing 21 is lower than that from the upper wing. The protruding height of the closing portion 72 counted by the plate 21.

再者，當滑動構件70位於施壓方向之滑動端的位置時，輔助封閉部77位於較拉片保持體60更後方的位置，且處於不與自由端部63之端面63a對面的狀態。又，輔助封閉部77成為如下狀態：在如後述圖14所示之將滑動構件70已向前方推入時，與自由端部63之端面63a對面(位於自由端部63之端面63a之下方)。Further, when the sliding member 70 is located at the sliding end of the pressing direction, the auxiliary closing portion 77 is located further rearward than the tab holding body 60, and is in a state of not facing the end surface 63a of the free end portion 63. Further, the auxiliary closing portion 77 is in a state of being opposed to the end surface 63a of the free end portion 63 (below the end surface 63a of the free end portion 63) when the sliding member 70 is pushed forward as shown in Fig. 14 which will be described later. .

於組裝上述本實施例3之滑件50之情形時，首先，與上述實施例1同樣地將滑動構件70與螺旋彈簧5組裝於滑件本體20。其次，為將拉片6安裝於拉片保持體60，將拉片6之安裝軸部6b***並收容於滑動構件70之收容溝槽部78(參照圖13)。此時，將自上翼板21算起之輔助封閉部77的突出高度設定成低於自上翼板21算起之封閉部72的突出高度，因此可使拉片6之安裝軸部6b不受輔助封閉部77干擾而容易地導引並收容於滑動構件70之收容溝槽部78。In the case where the slider 50 of the third embodiment described above is assembled, first, the sliding member 70 and the coil spring 5 are assembled to the slider body 20 in the same manner as in the first embodiment. Next, in order to attach the handle 6 to the handle holding body 60, the attachment shaft portion 6b of the pull tab 6 is inserted into and received in the accommodation groove portion 78 of the slide member 70 (see Fig. 13). At this time, the protruding height of the auxiliary closing portion 77 from the upper blade 21 is set lower than the protruding height of the closing portion 72 from the upper blade 21, so that the mounting shaft portion 6b of the tab 6 can be prevented. The auxiliary closing portion 77 interferes and is easily guided and housed in the receiving groove portion 78 of the sliding member 70.

此外，藉由使收容於收容溝槽部78中的拉片6之安裝軸部6b向前方移動，而利用該安裝軸部6b將滑動構件70之封閉部72向前方推入。藉此，如圖14所示，滑動構件70抵抗螺旋彈簧5之施壓而前進，故由滑動構件70之封閉部72所封閉之插通間隙12開口，可經由該已開口之插通間隙12使拉片6之安裝軸部6b移動至收容空間11內。此時，拉片6之安裝軸部6b在收容於滑動構件70之收容溝槽部78中的狀態下一面推入滑動構件70一面移動，因此可一面利用拉片6之安裝軸部6b確實地推壓滑動構件70之封閉部72，一面使該安裝軸部6b穩定地移動至收容空間11內。Further, the mounting shaft portion 6b of the tab 6 accommodated in the housing groove portion 78 is moved forward, and the closing portion 72 of the sliding member 70 is pushed forward by the mounting shaft portion 6b. Thereby, as shown in FIG. 14, the sliding member 70 advances against the pressing force of the coil spring 5, so that the insertion gap 12 closed by the closing portion 72 of the sliding member 70 is opened, and the insertion gap 12 can be opened through the opening. The mounting shaft portion 6b of the pull tab 6 is moved into the accommodating space 11. At this time, the attachment shaft portion 6b of the pull tab 6 is moved while being pushed into the sliding member 70 while being accommodated in the accommodation groove portion 78 of the slide member 70. Therefore, the attachment shaft portion 6b of the pull tab 6 can be surely used. The closing portion 72 of the sliding member 70 is pressed to stably move the mounting shaft portion 6b into the accommodating space 11.

然後，若在拉片6之安裝軸部6b移動至收容空間11內之後，將該安裝軸部6b向上方提拉，則滑動構件70受到螺旋彈簧5施壓而移動至施壓方向側之滑動端，從而封閉拉片保持體60之自由端部63與上翼板21之間的插通間隙12。藉此，如圖15及圖16所示，可獲得將拉片6保持於拉片保持體60的本實施例3之滑件50。Then, when the attachment shaft portion 6b of the tab 6 is moved into the accommodating space 11, the mounting shaft portion 6b is pulled upward, and the sliding member 70 is pressed by the coil spring 5 to move to the pressing direction side. The end thus closes the insertion gap 12 between the free end 63 of the tab holder 60 and the upper wing 21. Thereby, as shown in FIGS. 15 and 16, the slider 50 of the third embodiment in which the tab 6 is held by the tab holding body 60 can be obtained.

再者，當拆卸保持於滑件50之拉片保持體60的拉片6時，用手指等向前方推壓滑動構件70，藉此使其抵抗螺旋彈簧5之施壓而前進。然後，將拉片6之安裝軸部6b收容於已前進之滑動構件70之收容溝槽部78，並使滑動構件70後退。藉此，可經由拉片保持體60之自由端部63與上翼板21之間的插通間隙12，容易地自收容空間11拔出拉片6之安裝軸部6b，從而拆卸拉片6。Further, when the tab 6 held by the tab holding body 60 of the slider 50 is detached, the sliding member 70 is pushed forward by a finger or the like, thereby advancing against the pressing force of the coil spring 5. Then, the attachment shaft portion 6b of the tab 6 is housed in the accommodation groove portion 78 of the advanced sliding member 70, and the slide member 70 is retracted. Thereby, the mounting shaft portion 6b of the pull tab 6 can be easily pulled out from the receiving space 11 via the insertion gap 12 between the free end portion 63 of the tab holding body 60 and the upper flap 21, thereby detaching the tab 6 .

上述本實施例3之滑件50中，設置於拉片保持體60之凸部64與設置於滑動構件70之凹部75係沿滑動構件70之滑動方向而形成，因此於拉片保持體60與滑動構件70之間沿上下方向彎曲而形成有縫隙13。因此，與上述實施例1同樣地，可防止較薄的布料等異物進入至拉片保持體60與滑動構件70之間的縫隙13。In the slider 50 of the third embodiment, the convex portion 64 provided in the handle holding body 60 and the concave portion 75 provided in the sliding member 70 are formed along the sliding direction of the sliding member 70, so that the pull tab holding body 60 and The slits 13 are formed by bending the sliding members 70 in the vertical direction. Therefore, similarly to the above-described first embodiment, it is possible to prevent foreign matter such as a thin cloth from entering the slit 13 between the tab holding body 60 and the sliding member 70.

此外，於本實施例3之滑件50中，於滑動構件70之後端部形成有輔助封閉部77，因此，例如，如圖17所示，當較厚的布料17自受到螺旋彈簧5施壓之滑動構件70的後方接近並發生碰撞時，滑動構件70之輔助封閉部77會成為障礙，從而可防止布料17進入至拉片保持體60之自由端部63與滑動構件70之間。Further, in the slider 50 of the third embodiment, the auxiliary closing portion 77 is formed at the rear end portion of the sliding member 70, and therefore, for example, as shown in Fig. 17, when the thicker cloth 17 is pressed by the coil spring 5 When the rear of the sliding member 70 approaches and collides, the auxiliary closing portion 77 of the sliding member 70 becomes an obstacle, so that the cloth 17 can be prevented from entering between the free end portion 63 of the tab holding body 60 and the sliding member 70.

又，例如，如圖18所示，即使於如較厚的布料17自受到螺旋彈簧5施壓之滑動構件70的後方接近，且該布料17將滑動構件70向前方推入之情形時，亦可在滑動構件70移動至與施壓方向為相反側之滑動端時，滑動構件70之輔助封閉部77封閉拉片保持體60之自由端部63與上翼板21之間的插通間隙12。因此，可防止較厚的布料17咬入至拉片保持體60之自由端部63與滑動構件70之間、或拉片保持體60之自由端部63與上翼板21之間。Further, for example, as shown in FIG. 18, even when the thick cloth 17 is approached from the rear of the sliding member 70 which is pressed by the coil spring 5, and the cloth 17 pushes the sliding member 70 forward, The auxiliary closing portion 77 of the sliding member 70 closes the insertion gap 12 between the free end portion 63 of the tab holding body 60 and the upper blade 21 when the sliding member 70 is moved to the sliding end opposite to the pressing direction. . Therefore, the thicker cloth 17 can be prevented from biting between the free end portion 63 of the tab holding body 60 and the sliding member 70, or between the free end portion 63 of the tab holding body 60 and the upper flap 21.

再者，上述實施例3之滑件50中，於拉片保持體60之自由端部63側之端面63a設有凸部64，並且於滑動構件70之封閉部72之上表面及輔助封閉部77之上表面設有凹部75及77b。但是，於本發明中，只要係為防止異物咬入至拉片保持體之自由端部與上翼板之間而於滑動構件中設置輔助封閉部之情形，便亦可採用如下滑件：例如，如圖19及圖20所示，於拉片保持體之自由端部側之端面未設置凸部及凹部，且於滑動構件之封閉部上表面及輔助封閉部上表面未設置凹部及凸部。Further, in the slider 50 of the above-described Embodiment 3, the end surface 63a on the free end portion 63 side of the tab holding body 60 is provided with the convex portion 64, and the upper surface of the closing portion 72 of the sliding member 70 and the auxiliary closing portion. The upper surface of 77 is provided with recesses 75 and 77b. However, in the present invention, as long as the auxiliary closing portion is provided in the sliding member to prevent foreign matter from being bitten into between the free end portion of the tab holding body and the upper blade, a slider such as the following may be employed: As shown in FIG. 19 and FIG. 20, the end surface on the free end side of the tab holding body is not provided with a convex portion and a concave portion, and the upper surface of the closing portion of the sliding member and the upper surface of the auxiliary closing portion are not provided with the concave portion and the convex portion. .

若作進一步具體說明，圖19及圖20所示之滑件51包括：滑件本體20；拉片保持體60，其係懸臂狀地固定於滑件本體20；滑動構件80，其係沿前後方向可滑動地配置於滑件本體20；螺旋彈簧5，其對滑動構件80向後方施壓；以及拉片6，其係保持於拉片保持體60。For further explanation, the slider 51 shown in FIGS. 19 and 20 includes: a slider body 20; a tab holding body 60 which is fixed in a cantilever manner to the slider body 20; and a sliding member 80 which is coupled to the front and rear The direction is slidably disposed on the slider body 20; a coil spring 5 that presses the sliding member 80 rearward; and a tab 6 that is held by the tab holding body 60.

於該滑件51中，於拉片保持體60中之自由端部63側之端面63a並未形成上述實施例3中之凸部64，該端面63a係形成為與上翼板21之上表面大致平行的平坦面。於該自由端部63側之平坦的端面63a與上翼板21之上表面之間，形成有可使拉片6之安裝軸部6b插通的插通間隙12。In the slider 51, the end surface 63a on the free end portion 63 side of the tab holding body 60 does not form the convex portion 64 in the above-described Embodiment 3, and the end surface 63a is formed to be on the upper surface of the upper blade 21. A substantially parallel flat surface. An insertion gap 12 through which the mounting shaft portion 6b of the tab 6 can be inserted is formed between the flat end surface 63a on the side of the free end portion 63 and the upper surface of the upper blade 21.

該滑件51中之滑動構件80包含：本體部71，其沿形成於上翼板21之滑動導引溝槽26滑動；封閉部82，其係突設於該本體部71之前後方向之中央部；輔助封閉部87，其係突設於本體部71之後端部；導引突條部73，其於本體部71之下表面(背面)側形成為壟狀凸條；以及導引部74，其係配置於本體部71之左右側緣部。又，於滑動構件70之封閉部72與輔助封閉部77之間，形成有可收容拉片6之安裝軸部6b的收容溝槽部78。The sliding member 80 in the slider 51 includes a body portion 71 that slides along a sliding guide groove 26 formed on the upper blade 21, and a closing portion 82 that is provided in the center of the front and rear directions of the body portion 71. The auxiliary closing portion 87 is provided at the rear end portion of the main body portion 71; the guiding protrusion portion 73 is formed as a ridge-shaped ridge on the lower surface (back surface) side of the main body portion 71; and the guiding portion 74 It is disposed on the left and right side edge portions of the main body portion 71. Further, between the closing portion 72 of the sliding member 70 and the auxiliary closing portion 77, a receiving groove portion 78 for accommodating the mounting shaft portion 6b of the tab 6 is formed.

又，於封閉部82之上表面82a及輔助封閉部87之上表面87a並未形成上述實施例3中之凹部75及凹部77b，該等上表面82a、87a係形成為與拉片保持體60中之自由端部63側之端面63a平行的平坦面。再者，輔助封閉部87係以自上翼板21算起之輔助封閉部87的突出高度低於自上翼板21算起之封閉部82的突出高度之方式而形成。Further, the concave portion 75 and the concave portion 77b in the above-described third embodiment are not formed on the upper surface 82a of the closing portion 82 and the upper surface 87a of the auxiliary closing portion 87, and the upper surfaces 82a, 87a are formed to be in contact with the tab holding body 60.

Further, the auxiliary closing portion 87 is formed such that the protruding height of the auxiliary closing portion 87 from the upper blade 21 is lower than the protruding height of the closing portion 82 from the upper blade 21.

即使為具有上述構成之滑件51，亦可於滑動構件80之收容溝槽部78中收容有拉片6之安裝軸部6b的狀態下使該滑動構件80滑動，因此可穩定地進行拉片6之安裝或拆卸。又，即使於較厚的布料自受到螺旋彈簧5施壓之滑動構件80之後方接近並發生碰撞，且該布料使滑動構件80以向前方推入之方式而滑動時，滑動構件80之輔助封閉部87亦可封閉拉片保持體60之自由端部63與上翼板21之間的插通間隙12。因此，可有效地防止拉片保持體60之自由端部63與滑動構件80之間、或拉片保持體60之自由端部63與上翼板21之間咬入較厚的布料。Even in the slider 51 having the above-described configuration, the sliding member 80 can be slid in a state in which the mounting shaft portion 6b of the tab 6 is accommodated in the housing groove portion 78 of the sliding member 80, so that the slider can be stably pulled. 6 installation or removal. Further, even when the thick cloth is approached and collided after the sliding member 80 pressed by the coil spring 5, and the cloth slides the sliding member 80 in such a manner as to push forward, the auxiliary member of the sliding member 80 is closed. The portion 87 can also close the insertion gap 12 between the free end 63 of the tab holding body 60 and the upper wing 21. Therefore, it is possible to effectively prevent the thicker cloth from being bitten between the free end portion 63 of the tab holding body 60 and the sliding member 80, or between the free end portion 63 of the tab holding body 60 and the upper flap 21.

再者，在將滑動構件240***至滑動導引溝槽226時，使滑動構件240之未圖示之導引部嵌著於上翼板221之未圖示之導引部嵌著溝槽。然後，將滑動構件240***至滑動導引溝槽226後，使豎立設置於上翼板221之後端部的未圖示之卡止片向彼此接近之方向壓彎，並加以緊固，藉此將滑動構件240以受到螺旋彈簧施壓之狀態可滑動地安裝於上翼板221。Further, when the slide member 240 is inserted into the slide guide groove 226, a guide portion (not shown) of the slide member 240 is fitted to a guide portion (not shown) of the upper blade 221 to be fitted with a groove. Then, after the sliding member 240 is inserted into the sliding guide groove 226, the locking pieces (not shown) which are erected at the rear end portions of the upper blade 221 are bent in the direction in which they approach each other, and are fastened thereby. The sliding member 240 is slidably attached to the upper blade 221 in a state of being pressed by a coil spring.

繼而，於組裝有滑動構件240及螺旋彈簧之滑件本體220中組裝停止爪體250、拉片保持體230及板彈簧260。具體而言，將停止爪體250自上方***至滑件本體220之爪體支持部228，以可上下搖動之方式樞支該停止爪體250。另一方面，將板彈簧260扣合並保持於形成於拉片保持體230之內壁的板彈簧保持部238。Then, the stopper claw 250, the tab holding body 230, and the leaf spring 260 are assembled in the slider body 220 in which the sliding member 240 and the coil spring are assembled. Specifically, the stopping claw 250 is inserted into the claw supporting portion 228 of the slider body 220 from above, and the stopping claw 250 is pivotally supported by rocking up and down. On the other hand, the leaf spring 260 is fastened and held by the leaf spring holding portion 238 formed on the inner wall of the handle holding body 230.

進而，使保持有板彈簧260之拉片保持體230之固定端部231自滑件本體220之前端嵌入至嵌著溝槽部229，其後，利用衝頭(punch)等自上表面側壓碎上翼板221之一部分而將拉片保持體230緊固並固定於上翼板221。藉此，將拉片保持體230組裝於滑件本體220。此時，滑動構件240受到螺旋彈簧施壓而位於施壓方向側之滑動端，因此形成於拉片保持體230之自由端部233與上翼板221之間的插通間隙成為被滑動構件240之封閉部242所封閉之狀態。Further, the fixed end portion 231 of the tab holding body 230 holding the leaf spring 260 is fitted into the groove portion 229 from the front end of the slider body 220, and thereafter, pressed from the upper surface side by a punch or the like. A portion of the upper flap 221 is broken to fasten and fix the tab holding body 230 to the upper flap 221. Thereby, the tab holding body 230 is assembled to the slider body 220. At this time, since the sliding member 240 is pressed by the coil spring and is located at the sliding end on the pressing direction side, the insertion gap formed between the free end portion 233 of the tab holding body 230 and the upper blade 221 becomes the member to be slid by the sliding member 240. The state in which the closing portion 242 is closed.

如上所述將停止爪體250、拉片保持體230及板彈簧260組裝於滑件本體220後，進行將拉片6安裝於拉片保持體230之操作。具體而言，使拉片6之安裝軸部6b自後方側***至拉片保持體230之自由端部233與上翼板221之間所形成的插通間隙，並一面藉由該安裝軸部6b使滑動構件240之封閉部242抵抗螺旋彈簧之施壓而向前方推入，一面使拉片6之安裝軸部6b移動至拉片保持體230之退避部236內。After the stopping claw 250, the tab holding body 230, and the leaf spring 260 are assembled to the slider body 220 as described above, the operation of attaching the tab 6 to the tab holding body 230 is performed. Specifically, the mounting shaft portion 6b of the tab 6 is inserted from the rear side into the insertion gap formed between the free end portion 233 of the tab holding body 230 and the upper blade 221, and the mounting shaft portion is provided by the mounting shaft portion. 6b, the closing portion 242 of the sliding member 240 is pushed forward against the pressing force of the coil spring, and the mounting shaft portion 6b of the tab 6 is moved into the retracting portion 236 of the tab holding body 230.

繼而，於移動至施壓方向側之滑動端的滑動構件240之收容溝槽部248***拉片6之安裝軸部6b，進而藉由該安裝軸部6b使滑動構件240之前方封閉部247抵抗螺旋彈簧之施壓而向前方推入。藉此，使拉片6之安裝軸部6b移動至收容空間11。此時，移動至收容部237的拉片6之安裝軸部6b被導引至停止爪體250之上下臂部252、253之間加以保持。Then, the receiving groove portion 248 of the sliding member 240 that is moved to the sliding end of the pressing direction side is inserted into the mounting shaft portion 6b of the pull tab 6, and the front side closing portion 247 of the sliding member 240 is prevented from resisting the spiral by the mounting shaft portion 6b. The spring is pressed and pushed forward. Thereby, the attachment shaft portion 6b of the tab 6 is moved to the accommodating space 11. At this time, the attachment shaft portion 6b of the tab 6 that has moved to the accommodating portion 237 is guided to and held between the lower arm portions 252, 253 above the stopper claw 250.

然後，在使拉片6之安裝軸部6b移動至收容部237內時，安裝軸部6b對滑動構件240之推壓得到解除，因此滑動構件240受到螺旋彈簧施壓而移動至施壓方向側之滑動端，拉片保持體230之自由端部233與上翼板221之間的插通間隙被滑動構件240之封閉部242所封閉。藉此，可獲得將拉片6保持於拉片保持體230的本實施例4之滑件210。Then, when the attachment shaft portion 6b of the tab 6 is moved into the accommodating portion 237, the pressing of the slidable member 240 by the attachment shaft portion 6b is released, so that the sliding member 240 is pressed by the coil spring to move to the pressing direction side. The sliding end, the insertion gap between the free end portion 233 of the tab holding body 230 and the upper blade 221 is closed by the closing portion 242 of the sliding member 240. Thereby, the slider 210 of the fourth embodiment in which the tab 6 is held by the tab holding body 230 can be obtained.

以上之本實施例4之滑件210與上述實施例1等同樣，可使滑動構件240不與拉片保持體230之自由端部233接觸而順暢地滑動，因此可穩定地進行拉片6之安裝或拆卸。又，藉由設置於拉片保持體230的凸部234與設置於滑動構件240的凹部245，拉片保持體230與滑動構件240之間所形成的縫隙沿上下方向彎曲，因此可防止較薄的布料等異物進入至該縫隙。In the slide member 210 of the fourth embodiment, as in the first embodiment and the like, the slide member 240 can be smoothly slid without coming into contact with the free end portion 233 of the tab holding body 230, so that the pull tab 6 can be stably performed. Install or disassemble. Further, by the convex portion 234 provided to the tab holding body 230 and the concave portion 245 provided in the sliding member 240, the slit formed between the tab holding body 230 and the sliding member 240 is bent in the up and down direction, thereby preventing thinning Foreign matter such as cloth enters the gap.

再者，於本實施例4之滑件210中，亦可例如增大滑件本體220及滑動構件240之滑件長度方向之尺寸，進而於滑動構件240中之封閉部242之後方設置如上述實施例3中所說明之突設高度較封閉部242之突設高度更低之輔助封閉部。Furthermore, in the slider 210 of the fourth embodiment, for example, the slider body 220 and the sliding member 240 may be increased in the longitudinal direction of the slider, and further disposed behind the closing portion 242 of the sliding member 240 as described above. The auxiliary closing portion of the protruding height described in the third embodiment is lower than the protruding height of the closing portion 242.

再者，於上述實施例1~4及變形例中，滑件除了於上翼板具有拉片保持體以外，亦可於下翼板具有拉片保持體。Further, in the above-described first to fourth embodiments and the modifications, the slider may have a tab holding body in addition to the upper blade, and may have a tab holding body in the lower blade.
