拉鏈1具有左右一對拉鏈鏈帶2、用以將拉鏈鏈帶2開合之滑件5、及可分離之止擋6。拉鏈鏈帶2係於拉鏈鏈布3之對向側緣安裝拉鏈鏈齒4而成者。典型而言，拉鏈鏈布3係梭織物、針織物、或包含該等兩者之組織之布。典型而言，拉鏈鏈齒4包含樹脂或金屬鏈齒之排列，或者包含環扣狀鏈齒。典型而言，滑件5係樹脂製或金屬製滑件。藉由滑件5之前進，左右之拉鏈鏈齒4及拉鏈鏈帶2結合，從而拉鏈1閉合。藉由滑件5之後退，左右之拉鏈鏈齒4及拉鏈鏈帶2變為非結合，從而拉鏈1打開。由於拉鏈1具有可分離之止擋6，故而左右一對拉鏈鏈帶2可取相互完全分離之狀態。再者，於本說明書中，「典型」意欲表示示例，但並不限於此。The zipper 1 has a pair of left and right zipper chain belts 2, a slider 5 for opening and closing the zipper chain belt 2, and a detachable stop 6. The fastener chain 2 is formed by attaching fastener elements 4 to opposite side edges of the fastener chain cloth 3. Typically, the zipper chain fabric 3 is a woven fabric, a knitted fabric, or a fabric including both. Typically, the zipper element 4 includes an arrangement of resin or metal elements, or includes loop-shaped elements. Typically, the slider 5 is a resin or metal slider. When the slider 5 advances, the left and right zipper teeth 4 and the zipper chain belt 2 are combined, so that the zipper 1 is closed. When the slider 5 moves backward, the left and right zipper teeth 4 and the zipper chain belt 2 become uncoupled, and the zipper 1 is opened. Since the zipper 1 has a separable stop 6, the pair of left and right zipper chain belts 2 can be completely separated from each other. Furthermore, in this specification, "typical" is intended to mean an example, but is not limited to this.
根據圖4及圖6可知，滑件5具有上翼板51、下翼板52、將上翼板51與下翼板52連結之連結柱53、及自上翼板51之側緣朝向下翼板52突出或自下翼板52之側緣朝向上翼板51突出之1個以上之凸緣部54。於上翼板51及/或下翼板52結合拉片安裝柱(未圖示)，從而可安裝拉片(未圖示)。滑件5於連結柱53之兩側具有導入口57，於導入口57之相反側具有一個嚙合口58。於滑件5後退時，結合狀態之左右之拉鏈鏈齒4自滑件5之嚙合口58進入至滑件5內，藉由滑件5之連結柱53分離之非結合狀態之左右之拉鏈鏈齒4經由滑件5之左右之導入口57而脫離至滑件5外。於在前後方向上滑件5位於後端位置時，止擋6可分離。根據下述說明亦可理解，藉由自止擋6之第1構件7分離第2構件8，可簡單地使止擋6成為分離狀態。As can be seen from FIGS. 4 and 6, the slider 5 has an upper wing plate 51, a lower wing plate 52, a connecting post 53 that connects the upper wing plate 51 and the lower wing plate 52, and from the side edge of the upper wing plate 51 toward the lower wing One or more flange portions 54 that the plate 52 protrudes or protrudes from the side edge of the lower wing plate 52 toward the upper wing plate 51. A pull-tab mounting post (not shown) is combined with the upper wing plate 51 and/or the lower wing plate 52 so that a pull-tab (not shown) can be installed. The slider 5 has introduction ports 57 on both sides of the connecting post 53 and an engagement port 58 on the opposite side of the introduction port 57. When the slider 5 moves backward, the left and right fastener elements 4 in the combined state enter into the slider 5 from the engagement opening 58 of the slider 5, and the left and right fastener chains in the uncoupled state separated by the connecting post 53 of the slider 5 The teeth 4 are disengaged from the slider 5 through the introduction ports 57 on the left and right of the slider 5. When the slider 5 is at the rear end position in the front-rear direction, the stopper 6 can be separated. It can also be understood from the following description that by separating the second member 8 from the first member 7 of the stopper 6, the stopper 6 can be easily separated.
於本說明書中，對照滑件5之移動方向理解「前後方向」。對照藉由滑件5而變為結合、非結合之左右一對拉鏈鏈帶2理解「左右方向」。「上下方向」係與前後方向及左右方向正交之方向。對照本說明書中所包含之特定之敍述，可重新定義該等用語。例如，上下方向與滑件5之連結柱53之延伸方向一致。In this specification, the "front-back direction" is understood in accordance with the moving direction of the slider 5. Comparing the pair of left and right zipper chain belts 2 that become joined and unjoined by the slider 5, understand the "left and right direction". "Up-down direction" is a direction orthogonal to the front-rear direction and the left-right direction. In contrast to the specific descriptions contained in this specification, these terms can be redefined. For example, the vertical direction coincides with the extending direction of the connecting post 53 of the slider 5.
止擋6係可分離之止擋，具有互為獨立之構件之第1構件7及第2構件8。第1構件7與第2構件8可相互結合及分離。第1構件7固定於左右一對拉鏈鏈布3之一者，第2構件8固定於左右一對拉鏈鏈布3之另一者。即，除第1構件7固定於左側拉鏈鏈布3且第2構件8固定於右側拉鏈鏈布3之形態以外，還可假定第1構件7固定於右側拉鏈鏈布3且第2構件8固定於左側拉鏈鏈布3之形態。第1構件7例如藉由在模具內配置有拉鏈鏈布3之狀態下將熔融塑膠射出成形而製造。第2構件8亦相同。The stop 6 is a separable stop, and has a first member 7 and a second member 8 that are independent members from each other. The first member 7 and the second member 8 can be coupled to and separated from each other. The first member 7 is fixed to one of the left and right pair of fastener chains 3, and the second member 8 is fixed to the other of the right and left pair of fastener chains 3. That is, in addition to the form in which the first member 7 is fixed to the left fastener chain 3 and the second member 8 is fixed to the right fastener chain 3, it can be assumed that the first member 7 is fixed to the right fastener chain 3 and the second member 8 is fixed In the form of zipper chain cloth 3 on the left. The first member 7 is manufactured, for example, by injection molding molten plastic in a state where the fastener chain 3 is arranged in the mold. The second member 8 is also the same.
第1構件7包含配置於較於前後方向上移動之滑件5之後端位置更靠後方之第1基部10、及用以將滑件5定位於前後方向上之後端位置之定位部30。定位部30係自第1基部10向前方延伸之部分。定位部30包含經由滑件5之嚙合口58插入至滑件5內之插入部31、供滑件5之凸緣部54自槽前端導入之槽32、及與插入部31之間夾著槽32之壁33。藉由插入部31經由滑件5之嚙合口58插入至滑件5內，促進將滑件5保持於前後方向上之後端位置，從而促進插入部40更順利地插入至滑件5內。The first member 7 includes a first base 10 disposed behind the rear end position of the slider 5 that moves in the front-rear direction, and a positioning portion 30 for positioning the slider 5 at the rear end position in the front-rear direction. The positioning portion 30 is a portion that extends forward from the first base 10. The positioning portion 30 includes an insertion portion 31 inserted into the slider 5 through the engagement opening 58 of the slider 5, a groove 32 through which the flange portion 54 of the slider 5 is introduced from the front end of the groove, and a groove sandwiched between the insertion portion 31 The wall of 32 33. The insertion portion 31 is inserted into the slider 5 through the engagement opening 58 of the slider 5 to promote the holding of the slider 5 at the rear end position in the front-rear direction, thereby facilitating the insertion of the insertion portion 40 into the slider 5 more smoothly.
於將插入部31經由滑件5之嚙合口58插入至滑件5內時，滑件5之左側之凸緣部54插入至槽32。適當地設定槽32之左右寬度，進一步促進滑件5保持於定位部30上。於滑件5位於後端位置時，定位部30之壁33與滑件5之左側之凸緣部54接觸，從而阻止滑件5之左側位移。再者，亦假定省略定位部30之形態。When the insertion portion 31 is inserted into the slider 5 through the engagement opening 58 of the slider 5, the flange portion 54 on the left side of the slider 5 is inserted into the groove 32. Appropriately setting the left and right widths of the groove 32 further promotes the slider 5 to be held on the positioning portion 30. When the slider 5 is at the rear end position, the wall 33 of the positioning portion 30 comes into contact with the flange portion 54 on the left side of the slider 5, thereby preventing the left side of the slider 5 from being displaced. Furthermore, it is assumed that the positioning unit 30 is omitted.
第2構件8包含沿著與前後方向正交之左右方向插入至滑件5內之插入部40、與插入部40之前端結合之拉鏈鏈齒部41、於前後方向上延伸之壁42、以及供插入部40及壁42連結且與第1基部10重合之第2基部20。插入部40插入至滑件5之上翼板51與下翼板52之間，於若干形態中，經由自上翼板51向下方突出之上部凸緣部54與自下翼板52向上方突出之下部凸緣部54之間之間隙插入至上翼板51與下翼板52之間。如此一來，要求插入部40較佳地通過較窄之上下寬度之間隙。再者，第2構件8之插入部40於插入至滑件5內之部分與第2基部20之間亦包含插入至下述槽88(參照圖5)之部分。The second member 8 includes an insertion portion 40 inserted into the slider 5 in the left-right direction orthogonal to the front-rear direction, a fastener element 41 coupled to the front end of the insertion portion 40, a wall 42 extending in the front-rear direction, and The second base 20 to which the insertion portion 40 and the wall 42 are connected and overlap the first base 10. The insertion portion 40 is inserted between the upper wing 51 and the lower wing 52 of the slider 5, and in some forms, the upper flange 54 and the lower wing 52 project upward from the upper wing 51 and project downward The gap between the lower flange portion 54 is inserted between the upper wing plate 51 and the lower wing plate 52. In this way, the insertion portion 40 is required to preferably pass through the narrower gap between the upper and lower widths. Furthermore, the insertion portion 40 of the second member 8 includes a portion inserted into the groove 88 (see FIG. 5) described below between the portion inserted into the slider 5 and the second base 20.
典型而言，插入部40具有於第2基部20與拉鏈鏈齒部41之間直線狀地延伸之插入端。典型而言，插入部40之插入端具有於插入方向上前端較細之形狀。插入部40為了更順利地插入至滑件5內，而於上下方向上具有較拉鏈鏈齒部41小之厚度。Typically, the insertion portion 40 has an insertion end extending linearly between the second base portion 20 and the fastener element 41. Typically, the insertion end of the insertion portion 40 has a shape with a thinner front end in the insertion direction. In order to insert into the slider 5 more smoothly, the insertion portion 40 has a thickness smaller than that of the fastener element 41 in the vertical direction.
壁42包含與滑件5之凸緣部54碰撞之部分，於上下方向上可具有較插入部40大之厚度。於在滑件5之上翼板51及下翼板52設置一對右側之凸緣部54之情形時，對應於此而設置上下一對壁42。拉鏈鏈齒部41藉由滑件5之前進而進入至滑件5內，並與左側拉鏈鏈齒4結合(參照圖12)。拉鏈鏈齒部41以於插入部40之樞轉時不與滑件5碰撞之方式設置於適當之位置。The wall 42 includes a portion that collides with the flange portion 54 of the slider 5 and may have a larger thickness than the insertion portion 40 in the up-down direction. When a pair of right flange portions 54 are provided on the upper wing 51 and the lower wing 52 of the slider 5, a pair of upper and lower walls 42 are provided corresponding to this. The fastener element 41 enters into the slider 5 by the front of the slider 5, and is combined with the left fastener element 4 (see FIG. 12). The fastener element 41 is provided at an appropriate position so as not to collide with the slider 5 when the insertion portion 40 pivots.
插入部31具有至少部分地接受插入至滑件5之第2構件8之插入部40之接受部35。於滑件5中，第2基部20之插入部40插入至插入部31之接受部35，從而避免或抑制第1及第2構件7、8之上下方向之分離。於在滑件5之上翼板51及下翼板52設置一對左側之凸緣部54之情形時，對應於此而於定位部30設置上下一對槽32、及上下一對壁33(參照圖9)。插入部31、槽32、及壁33均以與第1基部10分離之方式沿著前後方向延伸。The insertion portion 31 has a receiving portion 35 that at least partially receives the insertion portion 40 inserted into the second member 8 of the slider 5. In the slider 5, the insertion portion 40 of the second base portion 20 is inserted into the receiving portion 35 of the insertion portion 31, thereby preventing or suppressing the separation of the first and second members 7, 8 in the up-down direction. When a pair of left flange portions 54 are provided on the upper wing plate 51 and the lower wing plate 52 of the slider 5, a pair of upper and lower grooves 32 and a pair of upper and lower walls 33 are provided on the positioning portion 30 corresponding to this (See Figure 9). The insertion portion 31, the groove 32, and the wall 33 all extend in the front-rear direction so as to be separated from the first base portion 10.
於滑件5自前後方向上之後端位置前進之過程中(參照圖12)，藉由滑件5之連結柱53與左右之凸緣部54之協動，左側之拉鏈鏈齒4與第2構件8之拉鏈鏈齒部41結合。第2構件8之插入部40插入至第1構件7之插入部31之接受部35，從而定位部30與插入部40結合。第2構件8之插入部40於第1基部10與第2基部20之重合過程中沿逆時針方向樞轉，並沿著左右方向插入至滑件5內。根據滑件5之前進，插入部40完全插入至第1構件7之插入部31之接受部35。由下述敍述可知，第1基部10與第2基部20之重合伴隨著第1基部10及/或第2基部20之旋轉。During the advancement of the slider 5 from the front-back direction to the rear end position (refer to FIG. 12), by the cooperation of the connecting post 53 of the slider 5 and the left and right flange portions 54, the left side fastener element 4 and the second The fastener element 41 of the member 8 is joined. The insertion portion 40 of the second member 8 is inserted into the receiving portion 35 of the insertion portion 31 of the first member 7, so that the positioning portion 30 is coupled to the insertion portion 40. The insertion portion 40 of the second member 8 pivots counterclockwise during the overlapping of the first base 10 and the second base 20, and is inserted into the slider 5 in the left-right direction. As the slider 5 advances, the insertion portion 40 is completely inserted into the receiving portion 35 of the insertion portion 31 of the first member 7. As can be seen from the following description, the coincidence of the first base 10 and the second base 20 is accompanied by the rotation of the first base 10 and/or the second base 20.
第1構件7之第1基部10包含第1接觸部14、第1輔助接觸部61、及(選用之)第3接觸部34。另一方面，第2基部20包含可與第1接觸部14接觸之第2接觸部24、可與第1輔助接觸部61接觸之第2輔助接觸部62、及可與(選用之)第3接觸部34接觸之第4接觸部44。於本實施形態中，第1及第2接觸部14、24於第1及第2基部10、20重合時相互接觸，根據第1及第2基部10、20之間隔之減少使第1基部10及/或第2基部20產生旋轉。進而，第1及第2輔助接觸部61、62於第1基部10及/或第2基部20之旋轉過程中相互接觸，提供用於第1基部10及/或第2基部20之旋轉之追加之接觸點。於圖13所示之旋轉之初期階段，第1及第2接觸部14、24相互接觸，於圖13之後之圖14或圖15所示之階段，第1及第2輔助接觸部61、62相互接觸。如此一來，根據第1及/或第2基部10、20之旋轉之進展，第1及第2基部10、20之接觸部位之數量增加。藉此，促進第1及/或第2基部10、20之穩定之旋轉，及/或插入部40較佳地插入至滑件5內之可能性提高。The first base portion 10 of the first member 7 includes a first contact portion 14, a first auxiliary contact portion 61, and (optionally) a third contact portion 34. On the other hand, the second base portion 20 includes a second contact portion 24 that can contact the first contact portion 14, a second auxiliary contact portion 62 that can contact the first auxiliary contact portion 61, and a (optional) third The fourth contact portion 44 that the contact portion 34 contacts. In the present embodiment, the first and second contact portions 14, 24 are in contact with each other when the first and second base portions 10, 20 overlap, and the first base portion 10 is reduced according to the decrease in the distance between the first and second base portions 10, 20. And/or the 2nd base 20 rotates. Furthermore, the first and second auxiliary contact portions 61 and 62 are in contact with each other during the rotation of the first base 10 and/or the second base 20 to provide additional rotation for the first base 10 and/or the second base 20 Contact point. At the initial stage of rotation shown in FIG. 13, the first and second contact parts 14, 24 are in contact with each other, and at the stage shown in FIG. 14 or FIG. 15 after FIG. 13, the first and second auxiliary contact parts 61, 62 Contact each other. As a result, according to the progress of the rotation of the first and/or second bases 10, 20, the number of contact portions of the first and second bases 10, 20 increases. Thereby, the possibility that the stable rotation of the first and/or second base portions 10 and 20 is promoted, and/or the insertion portion 40 is preferably inserted into the slider 5 is increased.
於第1及第2基部10、20重合時，第3及第4接觸部34、44接觸。第2基部20採取相對於第1基部10根據至少第1及第2接觸部14、24之接觸以及第3及第4接觸部34、44之接觸而傾斜之姿勢。相對於第2基部20結合之插入部40亦採取相對於第1基部10(或由第1構件7之定位部30保持之滑件5)傾斜之姿勢。於圖13所示之旋轉之初期階段，第2基部20及/或插入部40之傾斜之程度最大。於圖16所示之旋轉之後期階段，第2基部20及/或插入部40之傾斜之程度最小。插入部40之傾斜之程度根據第1及/或第2基部10、20之旋轉之進行變小，藉此，促進插入部40較佳地插入至滑件5內。再者，亦假定於第1基部10與第2基部20重合時第1基部10與第2基部20相互平行地配向之形態。When the first and second base portions 10 and 20 overlap, the third and fourth contact portions 34 and 44 are in contact. The second base 20 takes a posture inclined relative to the first base 10 based on at least the contact of the first and second contact portions 14 and 24 and the contact of the third and fourth contact portions 34 and 44. The insertion portion 40 coupled to the second base portion 20 also assumes a posture inclined with respect to the first base portion 10 (or the slider 5 held by the positioning portion 30 of the first member 7). At the initial stage of the rotation shown in FIG. 13, the second base 20 and/or the insertion portion 40 incline to the greatest extent. In the later stage of the rotation shown in FIG. 16, the second base 20 and/or the insertion portion 40 is inclined to the minimum extent. The degree of inclination of the insertion portion 40 becomes smaller according to the rotation of the first and/or second base portions 10 and 20, thereby promoting the insertion of the insertion portion 40 into the slider 5 preferably. In addition, it is also assumed that the first base 10 and the second base 20 are aligned parallel to each other when the first base 10 and the second base 20 overlap.
亦能夠以第1構件7與第2構件8結合之狀態下之第2基部20之姿勢為基準，掌握第2基部20相對於上述第1基部10之傾斜姿勢。作為追加或代替，第2基部20相對於上述第1基部10之傾斜姿勢可根據插入部40相對於左側之拉鏈鏈布3所存在之平面傾斜地延伸之狀態掌握。於第1及第2接觸部14、24接觸且第3及第4接觸部34、44接觸之狀態下，插入部40相對於左側之拉鏈鏈布3所存在之平面所成之角θ之最大值為20°以下、或15°以下、或10°以下。再者，於第1構件7與第2構件8結合之狀態下，插入部40相對於左側之拉鏈鏈布3所存在之平面所成之角θ為0°。It is also possible to grasp the inclined posture of the second base 20 relative to the first base 10 based on the posture of the second base 20 in a state where the first member 7 and the second member 8 are coupled. As an addition or alternative, the inclined posture of the second base portion 20 with respect to the first base portion 10 can be grasped based on the state where the insertion portion 40 extends obliquely with respect to the plane on which the fastener chain 3 on the left side exists. In a state where the first and second contact portions 14 and 24 are in contact and the third and fourth contact portions 34 and 44 are in contact, the maximum angle θ formed by the insertion portion 40 with respect to the plane where the left fastener chain 3 exists The value is 20° or less, or 15° or less, or 10° or less. In addition, in a state where the first member 7 and the second member 8 are coupled, the angle θ formed by the insertion portion 40 with respect to the plane where the fastener chain 3 on the left side exists is 0°.
未必限於此，但第1及第2基部10、20以磁性接著之方式構成，第1及第2基部10、20之間隔根據於第1及第2基部10、20間產生之磁吸引力而減少。若第1基部10與第2基部20根據磁吸引力重合，則因第1接觸部14與第2接觸部24之接觸而第1基部10及/或第2基部20旋轉，插入部40開始樞轉。使第1基部10與第2基部20接近至可磁性接著之程度地藉由磁吸引力，將第1基部10與第2基部20適當地對準，將插入部40插入至滑件5內。提供對於難以進行可分離之止擋之操作之幼兒或需要護理者或者單手或雙手不便之登山者而言亦可進行開合作業之止擋。當然，本止擋對於健全者而言亦較便利。It is not necessarily limited to this, but the first and second bases 10 and 20 are formed by magnetic bonding, and the interval between the first and second bases 10 and 20 is based on the magnetic attraction force generated between the first and second bases 10 and 20. cut back.

The first contact portion 14 is sandwiched between the first hook 81 and the containing portion 12. The first hook 81 is provided farther from the containing portion 12 than the first contact portion 14. Specifically, it is located behind the first contact portion 14 (the rearmost end of the first base portion 10 ). The second hook 82 is provided farther away from the opposing surface 22 than the second contact portion 24, specifically, is located behind the second contact portion 24 (the rearmost in the second base portion 20).

The pivoting speed of the insertion part 40 in the later stage of rotation shown in FIGS. 15 and 16 can be made higher than the pivoting speed of the insertion part 40 in the initial stage of rotation shown in FIGS. 13 and 14, thereby increasing the insertion part 40 Possibility to insert into slide 5.
第1接觸部14(滑動部141)與第2接觸部24(傾斜面241)之接觸提供用於第1基部10及/或第2基部20之旋轉(作為追加或代替，插入部40之樞轉)之第1接觸點。再者，於本案說明書中，所謂「接觸點」並不限於較窄之區域中之接觸(例如點接觸)，亦包含較廣之區域中之接觸(例如面接觸)。第1外周部13除具有第1接觸部14以外還具有第3接觸部34。第2外周部23除具有第2接觸部24以外還具有第4接觸部44。第3接觸部34與第4接觸部44之接觸提供用於第1基部10及/或第2基部20之旋轉(作為追加或代替，插入部40之樞轉)之第2接觸點。於若干形態中，第3接觸部34包含滑動面(例如平坦面)，第4接觸部44包含在該滑動面上滑動之滑動部。第3接觸部34所包含之滑動面鄰接於位於後端位置之滑件5之後方而設置，更詳細而言，(於後方)鄰接於第1構件7之插入部31之接受部35之上表面35m而設置。滑動面可為平坦面或傾斜面或該等之組合。第4接觸部44可為(於後方)鄰接於在前後方向上延伸之插入部40之插入端40m而設置之凸狀之滑動部。The contact between the first contact portion 14 (sliding portion 141) and the second contact portion 24 (inclined surface 241) provides for the rotation of the first base 10 and/or the second base 20 (as an addition or replacement, the pivot of the insertion portion 40 Turn) the first contact point. Furthermore, in the description of this case, the so-called "contact point" is not limited to contact in a narrow area (for example, point contact), but also includes contact in a wider area (for example, surface contact). The first outer peripheral portion 13 has a third contact portion 34 in addition to the first contact portion 14. The second outer peripheral portion 23 has a fourth contact portion 44 in addition to the second contact portion 24. The contact between the third contact portion 34 and the fourth contact portion 44 provides a second contact point for the rotation of the first base portion 10 and/or the second base portion 20 (in addition or instead, the pivoting of the insertion portion 40). In some forms, the third contact portion 34 includes a sliding surface (for example, a flat surface), and the fourth contact portion 44 includes a sliding portion that slides on the sliding surface. The sliding surface included in the third contact portion 34 is provided adjacent to the rear of the slider 5 at the rear end position, more specifically, (at the rear) adjacent to the receiving portion 35 of the insertion portion 31 of the first member 7 Surface 35m. The sliding surface may be a flat surface or an inclined surface or a combination of these. The fourth contact portion 44 may be a convex sliding portion provided (at the rear) adjacent to the insertion end 40m of the insertion portion 40 extending in the front-rear direction.
於第1接觸部14與第3接觸部34之間配置包含部12。包含部12夾於第1及第3接觸部14、34之間。於第2接觸部24與第4接觸部44之間配置對向面22。對向面22夾於第2及第4接觸部24、44之間。第1接觸部14於上下方向上位於較第3接觸部34更靠下方之位置。於上下方向上，第2接觸部24之最上方之位置與第4接觸部44之最上方之位置相同。因此，如圖13所示，於第1基部10與第2基部20重合時，第2構件8相對於第1構件7傾斜地配向。此時，第1構件7之插入部31之延伸方向與前方一致，第2構件8之插入部40之延伸方向與朝向前方斜右上方之方向一致。根據第1基部10及/或第2基部20之旋轉(作為追加或代替，插入部40之樞轉)，第2構件8之插入部40之延伸方向以與第1構件7之插入部31之延伸方向(即前方)一致之方式變化。插入部40之傾斜之程度根據第1及/或第2基部10、20之旋轉之進行變小，促進插入部40較佳地插入至滑件5內。亦假定第2構件8之插入部40之延伸方向自朝向前方斜右下方之方向以與第1構件7之插入部31之延伸方向(即前方)一致之方式變化之形態。The containing portion 12 is arranged between the first contact portion 14 and the third contact portion 34. The included portion 12 is sandwiched between the first and third contact portions 14 and 34. The opposing surface 22 is arranged between the second contact portion 24 and the fourth contact portion 44. The opposing surface 22 is sandwiched between the second and fourth contact portions 24 and 44. The first contact portion 14 is located below the third contact portion 34 in the vertical direction. In the vertical direction, the uppermost position of the second contact portion 24 is the same as the uppermost position of the fourth contact portion 44. Therefore, as shown in FIG. 13, when the first base 10 and the second base 20 overlap, the second member 8 is oriented obliquely with respect to the first member 7. At this time, the extending direction of the insertion portion 31 of the first member 7 coincides with the front, and the extending direction of the insertion portion 40 of the second member 8 coincides with the direction obliquely upward and toward the front. According to the rotation of the first base portion 10 and/or the second base portion 20 (as an addition or replacement, the pivoting of the insertion portion 40), the extension direction of the insertion portion 40 of the second member 8 is equal to that of the insertion portion 31 of the first member 7 The way in which the direction of extension (ie, the front) is consistent changes. The degree of inclination of the insertion portion 40 becomes smaller according to the rotation of the first and/or second base portions 10 and 20, which facilitates the insertion of the insertion portion 40 into the slider 5. It is also assumed that the extending direction of the insertion portion 40 of the second member 8 changes from the direction diagonally downward and rightward toward the front so as to coincide with the extending direction (ie, front) of the insertion portion 31 of the first member 7.
於若干形態中，插入部31構成為於左右方向上將滑件5傾斜地保持(參照圖9)，藉此，促進插入部40順利地插入至滑件5。根據第1基部10及/或第2基部20之旋轉(作為追加或代替，插入部40之樞轉)如上所述般位移之第2構件8之插入部40較佳地插入至滑件內之可能性提高。插入部31具有於左右方向上傾斜之上表面區域31m及/或下表面區域31n。上表面區域31m及下表面區域31n相對於左右方向或平面P1、P2或者拉鏈鏈布3之上表面或下表面以角度θ1、θ2傾斜。平面P1、P2係與和上下方向一致之軸線AX正交或者與拉鏈鏈布3之上表面或下表面平行之平面。規定上下方向上接受部35之開口寬度W35之上表面35m及下表面35n係相對於左右方向或平面P1、P2平行地配向。因此，接受部35之上板部及下板部之厚度於左右方向上變化。於圖9之圖示例中，上表面區域31m及下表面區域31n係朝向右側向上方傾斜之傾斜區域。亦假定上表面區域31m及下表面區域31n係朝向右側向下方傾斜之傾斜區域之形態。亦假定於插入部40設置1個以上之凸部藉此將滑件5傾斜地保持之形態。In some forms, the insertion portion 31 is configured to hold the slider 5 obliquely in the left-right direction (refer to FIG. 9 ), thereby promoting the smooth insertion of the insertion portion 40 into the slider 5. According to the rotation of the first base 10 and/or the second base 20 (as an addition or replacement, the pivot of the insertion part 40), the insertion part 40 of the second member 8 displaced as described above is preferably inserted into the slider The possibility increases. The insertion portion 31 has an upper surface area 31m and/or a lower surface area 31n inclined in the left-right direction. The upper surface area 31 m and the lower surface area 31 n are inclined at angles θ1 and θ2 with respect to the left-right direction or the planes P1 and P2 or the upper or lower surface of the fastener chain 3. The planes P1 and P2 are orthogonal to the axis AX that coincides with the up-down direction or parallel to the upper or lower surface of the fastener chain 3. The upper surface 35m and the lower surface 35n of the opening width W35 of the receiving portion 35 in the vertical direction are aligned parallel to the left-right direction or the planes P1 and P2. Therefore, the thickness of the upper plate portion and the lower plate portion of the receiving portion 35 changes in the left-right direction. In the example shown in FIG. 9, the upper surface area 31 m and the lower surface area 31 n are inclined areas inclined upward toward the right. It is also assumed that the upper surface area 31m and the lower surface area 31n are in the form of inclined areas inclined downward toward the right. It is also assumed that the insertion portion 40 is provided with one or more convex portions to hold the slider 5 obliquely.
於第1基部10及第2基部20之重合之初期階段、或者第1基部10及/或第2基部20之旋轉之初期階段(例如圖13及圖14所示之狀態)，獲得第1及第2接觸部14、24之接觸所實現之第1接觸點、以及第3及第4接觸部34、44之接觸所實現之第2接觸點。根據第1基部10與第2基部20之重合之態樣，第1接觸點於時間上先於第2接觸點產生(反之亦然)。第1接觸點與第2接觸點無須於時間軸上同時產生。At the initial stage of the coincidence of the first base 10 and the second base 20, or at the initial stage of the rotation of the first base 10 and/or the second base 20 (for example, the state shown in FIGS. 13 and 14), the first and The first contact point achieved by the contact of the second contact portions 14, 24, and the second contact point achieved by the contact of the third and fourth contact portions 34, 44. According to the superposition of the first base 10 and the second base 20, the first contact point occurs before the second contact point in time (or vice versa). The first contact point and the second contact point need not be generated simultaneously on the time axis.
第1及第2輔助接觸部61、62於滑動部141於傾斜面241下降之中途相互接觸。以即便第1及第2輔助接觸部61、62之接觸較遲亦可於圖15及圖16所示之旋轉之後期階段獲得之方式，適當地構成第1及第2輔助接觸部61、62。例如，輔助接觸部於外周部配置於適當之位置，及/或設計為適當之形狀及大小。第1輔助接觸部61於圓周方向上設置於第1接觸部14與第3接觸部34之間。同樣地，第2輔助接觸部62於圓周方向上設置於第2接觸部24與第4接觸部44之間。第1及第2輔助接觸部61、62與插入部40進入至滑件5內之時點同步地相互接觸。The first and second auxiliary contact portions 61 and 62 contact each other while the sliding portion 141 descends on the inclined surface 241. The first and second auxiliary contact portions 61, 62 are appropriately configured in such a manner that the contact of the first and second auxiliary contact portions 61, 62 can be obtained at a later stage of the rotation shown in FIGS. 15 and 16 even if they are late. . For example, the auxiliary contact portion is arranged at an appropriate position on the outer peripheral portion, and/or is designed to have an appropriate shape and size. The first auxiliary contact portion 61 is provided between the first contact portion 14 and the third contact portion 34 in the circumferential direction. Similarly, the second auxiliary contact portion 62 is provided between the second contact portion 24 and the fourth contact portion 44 in the circumferential direction. The first and second auxiliary contact portions 61 and 62 are in contact with each other synchronously when the insertion portion 40 enters the slider 5.
假定1個或2個以上之第1輔助接觸部61設置於第1外周部13、1個或2個以上之第2輔助接觸部62設置於第2外周部23之各種形態。以不妨礙藉由第1及第2接觸部14、24所實現之接觸點以及第3及第4接觸部34、44所實現之接觸點的第1基部10及/或第2基部20之旋轉之方式，設置第1及第2輔助接觸部61、62。因此，於2個以上之第1輔助接觸部61設置於第1外周部13之情形時，上下方向上之各第1輔助接觸部61之位置可不同。同樣地，於2個以上之第2輔助接觸部62設置於第2外周部23之情形時，上下方向上之各第2輔助接觸部62之位置可不同。It is assumed that one or more first auxiliary contact portions 61 are provided on the first outer peripheral portion 13, and one or more second auxiliary contact portions 62 are provided on the second outer peripheral portion 23 in various forms. So as not to hinder the rotation of the first base 10 and/or the second base 20 of the contact points realized by the first and second contact parts 14, 24 and the contact points realized by the third and fourth contact parts 34, 44 The first and second auxiliary contact portions 61 and 62 are provided. Therefore, when two or more first auxiliary contact portions 61 are provided on the first outer peripheral portion 13, the positions of the first auxiliary contact portions 61 in the vertical direction may be different. Similarly, when two or more second auxiliary contact portions 62 are provided on the second outer peripheral portion 23, the positions of the second auxiliary contact portions 62 in the vertical direction may be different.
於若干形態中，第1及第2輔助接觸部61、62構成為於第1基部10及/或第2基部20之旋轉過程中相互干涉。第1及第2輔助接觸部61、62具有沿著與第1基部10及/或第2基部20之旋轉方向相符之圓周方向延伸之傾斜面903、907、914、918。於若干形態中，第1及第2輔助接觸部61、62包含頂面902、906、913、917與傾斜面903、907、914、918之組合。於不大幅度阻礙第1基部10及/或第2基部20之旋轉之態樣中，獲得追加之接觸點。於第1及第2基部10、20重合時，第1基部10之第1輔助接觸部61(頂面902、906、傾斜面903、907)面向第2基部20側、即下方。於第1及第2基部10、20重合時，第2基部20之第2輔助接觸部62(頂面913、917、傾斜面914、918)面向第1基部10側、即上方。In some forms, the first and second auxiliary contact portions 61 and 62 are configured to interfere with each other during the rotation of the first base 10 and/or the second base 20. The first and second auxiliary contact portions 61 and 62 have inclined surfaces 903, 907, 914, and 918 extending in the circumferential direction corresponding to the rotation direction of the first base portion 10 and/or the second base portion 20. In some forms, the first and second auxiliary contact portions 61, 62 include a combination of top surfaces 902, 906, 913, 917 and inclined surfaces 903, 907, 914, 918. In a state where the rotation of the first base 10 and/or the second base 20 is not greatly hindered, additional contact points are obtained. When the first and second bases 10, 20 overlap, the first auxiliary contact portion 61 (top surfaces 902, 906, inclined surfaces 903, 907) of the first base 10 faces the second base 20 side, that is, downward. When the first and second bases 10, 20 overlap, the second auxiliary contact portion 62 (top surfaces 913, 917, inclined surfaces 914, 918) of the second base 20 faces the first base 10 side, that is, upward.
頂面902、906、913、917與傾斜面903、907、914、918於與第1基部10及/或第2基部20之旋轉方向相符之圓周方向上鄰接而設置。藉由頂面902、906、913、917及傾斜面903、907、914、918形成邊緣93、94、91、92。於第1基部10及/或第2基部20之旋轉過程中，第1輔助接觸部61之邊緣93、94與第2輔助接觸部62之邊緣91、92產生干涉。與於磁鐵11、21之間產生之磁吸引力對應之第1基部10及/或第2基部20之旋轉力獲勝，從而第1基部10及/或第2基部20之旋轉持續。藉由第1輔助接觸部61之邊緣93、94與第2輔助接觸部62之邊緣91、92接觸，第1基部10及/或第2基部20之旋轉穩定性提高。再者，亦假定如下形態，即，作為磁吸引力之追加或代替，於人之大拇指與人之食指之間將第1基部10及第2基部20自上下夾入藉此第1基部10及/或第2基部20旋轉。The top surfaces 902, 906, 913, 917 and the inclined surfaces 903, 907, 914, 918 are provided adjacent to each other in the circumferential direction corresponding to the rotation direction of the first base 10 and/or the second base 20. The top surfaces 902, 906, 913, 917 and the inclined surfaces 903, 907, 914, 918 form the edges 93, 94, 91, 92. During the rotation of the first base 10 and/or the second base 20, the edges 93 and 94 of the first auxiliary contact 61 interfere with the edges 91 and 92 of the second auxiliary contact 62. The rotation force of the first base 10 and/or the second base 20 corresponding to the magnetic attractive force generated between the magnets 11 and 21 wins, and the rotation of the first base 10 and/or the second base 20 continues. By the edges 93 and 94 of the first auxiliary contact portion 61 contacting the edges 91 and 92 of the second auxiliary contact portion 62, the rotational stability of the first base 10 and/or the second base 20 is improved. In addition, it is also assumed that the first base 10 and the second base 20 are sandwiched from above and below as an addition or replacement of the magnetic attraction force between the human thumb and the human index finger And/or the second base 20 rotates.
進一步對第1基部10之第1外周部13進行說明。傾斜面914、918自頂面913、917向逆時針方向傾斜。於逆時針方向上，鄰接於傾斜面914、918設置平坦面915、919。於第1及第2基部10、20結合時，第2基部20之第2輔助接觸部62之頂面902、906與平坦面915、919接觸(參照圖10及11)。The first outer peripheral portion 13 of the first base 10 will be further described. The inclined surfaces 914 and 918 are inclined counterclockwise from the top surfaces 913 and 917. In the counterclockwise direction, flat surfaces 915 and 919 are provided adjacent to the inclined surfaces 914 and 918. When the first and second bases 10 and 20 are joined, the top surfaces 902 and 906 of the second auxiliary contact portion 62 of the second base 20 are in contact with the flat surfaces 915 and 919 (see FIGS. 10 and 11 ).
傾斜面903、907自頂面902、906向順時針方向傾斜。於順時針方向上，鄰接於傾斜面903、907設置平坦面904、908。於第1及第2基部10、20結合時，第1基部10之第1輔助接觸部61之頂面913、917與平坦面904、908接觸(參照圖10及11)。The inclined surfaces 903 and 907 are inclined clockwise from the top surfaces 902 and 906. In the clockwise direction, flat surfaces 904 and 908 are provided adjacent to the inclined surfaces 903 and 907. When the first and second base portions 10 and 20 are joined, the top surfaces 913 and 917 of the first auxiliary contact portion 61 of the first base portion 10 are in contact with the flat surfaces 904 and 908 (see FIGS. 10 and 11 ).
於若干形態中，包含部12之頂面為平坦面，及/或包含部12具有錐台形狀(於圖示例中為圓錐台形狀)。可更接近包含部12之頂面地配置磁鐵或磁性體11。同樣地，於若干形態中，對向面22為平坦面，從而促進更接近對向面22地配置磁鐵或磁性體21。第2接觸部24設置於第2外周部23。In some forms, the top surface of the inclusion 12 is a flat surface, and/or the inclusion 12 has a truncated cone shape (a truncated cone shape in the illustrated example). The magnet or magnetic body 11 can be arranged closer to the top surface of the containing portion 12. Similarly, in some forms, the opposing surface 22 is a flat surface, which facilitates the placement of the magnet or magnetic body 21 closer to the opposing surface 22. The second contact portion 24 is provided on the second outer peripheral portion 23.
磁鐵11、21係具有N極及S極之永久磁鐵。磁鐵11、21之形狀並不限於圓柱形狀，亦可為角柱形狀(參照圖18)。再者，第1及第2構件7、8、尤其是第1及第2基部10、20由具有充分之磁導率之材料、例如塑膠材料(聚醯胺等)形成。於在包含部12之頂面121側配置磁鐵或磁性體11之S極之情形時，於第2基部20之對向面22之正下方配置磁鐵或磁性體21之N極。於在包含部12之頂面121側配置磁鐵或磁性體11之N極之情形時，於第2基部20之對向面22之正下方配置磁鐵或磁性體21之S極。再者，於使用磁鐵與磁性體之組合之情形時，無須注意磁鐵之極性之配置。The magnets 11 and 21 are permanent magnets having N poles and S poles. The shape of the magnets 11 and 21 is not limited to a cylindrical shape, and may be a prism shape (see FIG. 18). Furthermore, the first and second members 7, 8 and especially the first and second bases 10, 20 are formed of a material having sufficient magnetic permeability, such as a plastic material (polyamide, etc.). When the S pole of the magnet or magnetic body 11 is arranged on the top surface 121 side of the containing portion 12, the N pole of the magnet or magnetic body 21 is arranged directly under the opposing surface 22 of the second base 20. When the N pole of the magnet or magnetic body 11 is arranged on the top surface 121 side of the containing portion 12, the S pole of the magnet or magnetic body 21 is arranged directly under the opposing surface 22 of the second base 20. Furthermore, when using a combination of a magnet and a magnetic body, there is no need to pay attention to the configuration of the polarity of the magnet.
包含部12於左右方向上具有第1外周部13之寬度W13之1/2以上或2/3以上之寬度W12。代替或追加性地，磁鐵或磁性體11於左右方向上具有第1外周部13之寬度W13之1/2以上或2/3以上之寬度W11。可使用較大之磁鐵或磁性體11，從而即便在拉鏈1縫製於衣服之狀態下亦獲得充分之磁吸引力。磁鐵或磁性體21於左右方向上具有第2基部20之寬度W20之1/2以上或2/3以上之寬度W21。對向面22於左右方向上具有第2基部20之寬度之1/2以上或2/3以上之寬度。磁鐵或磁性體21於與上下方向正交之任意方向上具有較對向面22大之寬度。可使用較大之磁鐵或磁性體21，從而即便在拉鏈1縫製於衣服之狀態下亦獲得充分之磁吸引力。The included portion 12 has a width W12 of 1/2 or more or 2/3 or more of the width W13 of the first outer peripheral portion 13 in the left-right direction. Alternatively or additionally, the magnet or magnetic body 11 has a width W11 of 1/2 or more or 2/3 or more of the width W13 of the first outer peripheral portion 13 in the left-right direction. A larger magnet or magnetic body 11 can be used so that a sufficient magnetic attractive force is obtained even when the zipper 1 is sewn to clothes. The magnet or the magnetic body 21 has a width W21 of 1/2 or more or 2/3 or more of the width W20 of the second base 20 in the left-right direction. The facing surface 22 has a width of 1/2 or more or 2/3 or more of the width of the second base 20 in the left-right direction. The magnet or magnetic body 21 has a larger width than the facing surface 22 in any direction orthogonal to the up-down direction. A larger magnet or magnetic body 21 can be used so that a sufficient magnetic attractive force is obtained even when the zipper 1 is sewn to the clothes.
包含部12以自第1外周部13突出之方式設置。將包含於包含部12之磁鐵或磁性體11配置於更下方，從而提高與第2基部20之磁鐵或磁性體21之磁性耦合之可能性。於在包含部12包含永久磁鐵之形態中，由永久磁鐵11形成之磁場可達到更下方。根據圖8可知，永久磁鐵11之自N極朝向S極之磁力線沿著上下方向透過第1外周部13，且具有沿著包含部12之側面122延伸之線段(參照圖8之箭頭ML1)。不被第1外周部13及/或第1接觸部14等障礙部分妨礙之磁場之有效空間增加，從而有效地提高第1及第2基部10、20之磁性耦合之可能性。若第1及第2基部10、20磁性耦合，則第2基部20朝向第1基部10移動。第2基部20與第1基部10重合，第1基部10及/或第2基部20旋轉，從而第2構件8之插入部40插入至滑件5內。The included portion 12 is provided so as to protrude from the first outer peripheral portion 13. The magnet or magnetic body 11 included in the containing part 12 is arranged further below, thereby increasing the possibility of magnetic coupling with the magnet or magnetic body 21 of the second base 20. In the case where the containing portion 12 contains the permanent magnet, the magnetic field formed by the permanent magnet 11 can reach further below. As can be seen from FIG. 8, the magnetic field lines of the permanent magnet 11 from the N pole to the S pole pass through the first outer peripheral portion 13 in the up-down direction, and have a line segment extending along the side surface 122 of the containing portion 12 (see arrow ML1 in FIG. 8 ). The effective space of the magnetic field that is not obstructed by obstacles such as the first outer peripheral portion 13 and/or the first contact portion 14 increases, thereby effectively increasing the possibility of magnetic coupling of the first and second base portions 10 and 20. When the first and second bases 10 and 20 are magnetically coupled, the second base 20 moves toward the first base 10. The second base 20 overlaps the first base 10, the first base 10 and/or the second base 20 rotates, and the insertion portion 40 of the second member 8 is inserted into the slider 5.
由於沿著包含部12之側面122延伸之磁力線之線段，故而即便在第2基部20相對於第1基部10於左右方向上鄰接配置之情形時於第1及第2基部10、20亦產生充分之磁性耦合。第2基部20朝向第1基部10沿著左右方向移動，從而第2基部20與第1基部10重合。Due to the line segment of the magnetic field lines extending along the side surface 122 of the containing portion 12, even when the second base portion 20 is arranged adjacent to the first base portion 10 in the left-right direction, the first and second base portions 10, 20 are sufficiently generated. Magnetic coupling. The second base 20 moves in the left-right direction toward the first base 10 so that the second base 20 overlaps the first base 10.
於包含部12以自第1外周部13突出之方式設置之形態中，包含部12亦可包含具有相對較大之厚度之磁鐵或磁性體11。藉此，有效地提高第1及第2基部10、20之磁性耦合之可能性。於若干形態中，上下方向上之磁鐵或磁性體11之厚度大於上下方向上之磁鐵或磁性體21之厚度。In a form in which the containing portion 12 is provided to protrude from the first outer peripheral portion 13, the containing portion 12 may also include a magnet or magnetic body 11 having a relatively large thickness. This effectively increases the possibility of magnetic coupling of the first and second bases 10 and 20. In some forms, the thickness of the magnet or magnetic body 11 in the up-down direction is greater than the thickness of the magnet or magnetic body 21 in the up-down direction.
第1及第2接觸部14、24構成為根據與於第1及第2基部10、20間產生之磁吸引力對應之第1及第2基部10、20之間隔之減少使第1基部10及/或第2基部20旋轉。若第2基部20與第1基部10重合，則上下方向上之第1及第2基部10、20之間隔與於第1及第2基部10、20間產生之磁吸引力對應地減少。此時，第1基部10之第1接觸部14與第2基部20之第2接觸部24接觸，從而第1基部10及/或第2基部20旋轉。The first and second contact portions 14 and 24 are configured to make the first base portion 10 reduce the interval between the first and second base portions 10 and 20 corresponding to the magnetic attractive force generated between the first and second base portions 10 and 20. And/or the second base 20 rotates. When the second base portion 20 overlaps the first base portion 10, the interval between the first and second base portions 10, 20 in the vertical direction decreases in accordance with the magnetic attractive force generated between the first and second base portions 10, 20. At this time, the first contact portion 14 of the first base portion 10 is in contact with the second contact portion 24 of the second base portion 20, so that the first base portion 10 and/or the second base portion 20 rotates.
第1接觸部14設置於第1外周部13之形態相較於第1接觸部14設置於包含部12之形態，容許使用更大之磁鐵或磁性體11，從而於第1及第2基部10、20之磁性耦合方面有利。第2接觸部24設置於第2外周部23之形態亦相較於第2接觸部24設置於對向面22之形態，於第1及第2基部10、20之磁性耦合方面有利。The configuration in which the first contact portion 14 is provided in the first outer peripheral portion 13 allows the use of a larger magnet or magnetic body 11 than in the configuration in which the first contact portion 14 is provided in the inclusion portion 12, so that the first and second base portions 10 , 20 is advantageous in terms of magnetic coupling. The configuration in which the second contact portion 24 is provided on the second outer peripheral portion 23 is also advantageous in terms of magnetic coupling of the first and second base portions 10 and 20 compared to the configuration in which the second contact portion 24 is provided on the opposing surface 22.
未必限於此，但包含部12具有收容磁鐵或磁性體11之第1收容空間15，第1收容空間15之開口由第1蓋構件71封閉，第1蓋構件71卡止於第1外周部13(參照圖8)。第1蓋構件71並非卡止於包含部12，而是卡止於第1外周部13，藉此確保第1收容空間15之充分之容積。於圖示例中，第1外周部13具有設置於鄰接於包含部12(或其側面122)設置之孔之被卡止部73。第1蓋構件71之爪卡止於第1外周部13之被卡止部73。亦假定藉由嵌入成形將磁鐵或磁性體11部分地或整體地埋入至包含部12之形態。再者，亦假定於包含部12設置1個以上之孔從而磁鐵或磁性體11部分地露出之形態。It is not necessarily limited to this, but the containing portion 12 has a first housing space 15 that houses the magnet or magnetic body 11, the opening of the first housing space 15 is closed by the first cover member 71, and the first cover member 71 is locked to the first outer peripheral portion 13 (See Figure 8). The first cover member 71 is not locked to the containing portion 12 but to the first outer peripheral portion 13, thereby ensuring a sufficient volume of the first storage space 15. In the illustrated example, the first outer peripheral portion 13 has a locked portion 73 provided in a hole provided adjacent to the containing portion 12 (or its side surface 122 ). The claw of the first cover member 71 is locked to the locked portion 73 of the first outer peripheral portion 13. It is also assumed that the magnet or magnetic body 11 is partially or wholly embedded in the containing portion 12 by insert molding. In addition, it is also assumed that the inclusion portion 12 is provided with one or more holes so that the magnet or the magnetic body 11 is partially exposed.
未必限於此，但第2基部20具有收容磁鐵或磁性體21之第2收容空間25，第2收容空間25之開口由第2蓋構件72封閉，第2蓋構件72卡止於第2外周部23(參照圖8)。第2蓋構件72卡止於位於對向面22之周圍之第2外周部23，藉此確保第2收容空間25之充分之容積。於圖示例中，第2外周部23具有設置於對向面22之外周之孔中所設置之被卡止部74。第2蓋構件72之爪卡止於第2外周部23之被卡止部74。亦假定藉由嵌入成形將磁鐵或磁性體21部分地或整體地埋入至第2基部20之形態。再者，亦假定於對向面22設置1個以上之孔從而磁鐵或磁性體21部分地露出之形態。It is not necessarily limited to this, but the second base 20 has a second storage space 25 for storing the magnet or magnetic body 21, the opening of the second storage space 25 is closed by the second cover member 72, and the second cover member 72 is locked at the second outer peripheral portion 23 (refer to FIG. 8). The second cover member 72 is locked to the second outer peripheral portion 23 located around the opposing surface 22, thereby ensuring a sufficient volume of the second storage space 25. In the illustrated example, the second outer peripheral portion 23 has a locked portion 74 provided in a hole provided on the outer periphery of the facing surface 22. The claw of the second cover member 72 is locked to the locked portion 74 of the second outer peripheral portion 23. It is also assumed that the magnet or the magnetic body 21 is partially or wholly embedded in the second base 20 by insert molding. In addition, it is also assumed that one or more holes are provided in the opposing surface 22 so that the magnet or the magnetic body 21 is partially exposed.
於使用第1蓋構件71之情形時，可藉由將磁鐵或磁性體11導入至第1收容空間15內繼而藉由第1蓋構件71將第1收容空間15之開口封閉之簡單之作業組裝第1構件7。對於第2構件8亦相同。When the first cover member 71 is used, it can be assembled by introducing a magnet or magnetic body 11 into the first storage space 15 and then closing the opening of the first storage space 15 by the first cover member 71 First member 7. The same is true for the second member 8.
壁86設置於第1基部10之前端部10F。壁86具有與第1及/或第2基部10、20之旋轉方向相符之圓周方向(與第2基部20之旋轉方向為相反方向)上向下傾斜之向下傾斜面87，向下傾斜面87之下游端較滑件5之後端部於左右方向上突出。第2構件8之插入部40於在向下傾斜面87下降後，不與滑件5產生較大干涉而插入至滑件5內。壁86與包含部12之間之槽85之底面與第1外周部13之下表面一致。於壁86與第1外周部13之間形成槽88。槽88於空間上與第1構件7之插入部31之接受部35連通。如圖17所示，於插入部40配置於滑件5之下方時，插入部40可於壁86之向下傾斜面87向逆時針方向下降，繼而，沿順時針方向樞轉經由凸緣部間之間隙進入至滑件5。The wall 86 is provided at the front end 10F of the first base 10. The wall 86 has a downwardly inclined surface 87 inclined downward in a circumferential direction (the direction opposite to the direction of rotation of the second base 20) corresponding to the rotation direction of the first and/or second bases 10, 20 The downstream end of 87 protrudes in the left-right direction relative to the rear end of the slider 5. The insertion portion 40 of the second member 8 is inserted into the slider 5 without causing significant interference with the slider 5 after descending the downward inclined surface 87. The bottom surface of the groove 85 between the wall 86 and the containing portion 12 coincides with the lower surface of the first outer peripheral portion 13. A groove 88 is formed between the wall 86 and the first outer peripheral portion 13. The groove 88 spatially communicates with the receiving portion 35 of the insertion portion 31 of the first member 7. As shown in FIG. 17, when the insertion portion 40 is disposed below the slider 5, the insertion portion 40 can be lowered counterclockwise on the downward inclined surface 87 of the wall 86, and then, pivoted clockwise through the flange portion Between the gap into the slider 5.
第1及第2基部10、20分別具有大於左右寬度W10、W20之前後長度L10、L20。於插入部40配置於壁86之下方時，可減小第2構件8相對於第1構件7所成之角。例如，於插入部40自壁86之下方插入至滑件5及槽88內之過程中帶動安裝有拉鏈1之布之可能性降低。The first and second bases 10 and 20 have lengths L10 and L20 that are larger than the front and rear widths W10 and W20, respectively. When the insertion portion 40 is disposed below the wall 86, the angle formed by the second member 8 relative to the first member 7 can be reduced. For example, during insertion of the insertion portion 40 into the slider 5 and the groove 88 from below the wall 86, the possibility of driving the cloth with the zipper 1 installed is reduced.
圖13至圖16表示第1構件7之位置固定且第2構件8相對於第1構件7樞轉，但請注意未必限於此種態樣。即，亦假定第2構件8之位置固定且第1構件7相對於第2構件8樞轉之形態。又，亦假定第1及第2構件7、8相互樞轉之形態。再者，於第2基部20相對於第1基部10旋轉時，第1基部10之滑動部141之位置固定，第2基部20之傾斜面241沿圓周方向、明確而言沿逆時針方向(參照圖12之箭頭)位移。滑動部141之位置不改變，但傾斜面241沿逆時針方向位移。於此種情形時，亦可稱為滑動部141於傾斜面241上自傾斜面241之上游端滑動至下游端。於第1基部10相對於第2基部20旋轉時，第2基部20之傾斜面241之位置固定，第1基部10之滑動部141沿順時針方向位移。滑動部141於傾斜面241上自傾斜面241之上游端滑動至下游端。於在第1外周部13設置滑動部141之形態中，滑動部141可具有存在於與包含部12之頂面121實質上相同之高度或較該包含部12之頂面121低之高度的頂面。避免或抑制滑動部141成為第1及第2基部10、20之磁性接著之障礙。13 to 16 show that the position of the first member 7 is fixed and the second member 8 pivots relative to the first member 7, but please note that it is not necessarily limited to this form. That is, it is also assumed that the position of the second member 8 is fixed and the first member 7 pivots relative to the second member 8. Also, assume that the first and second members 7, 8 are pivoted to each other. Furthermore, when the second base 20 rotates relative to the first base 10, the position of the sliding portion 141 of the first base 10 is fixed, and the inclined surface 241 of the second base 20 is circumferential, specifically counterclockwise (refer to Arrow in Fig. 12) displacement. The position of the sliding portion 141 does not change, but the inclined surface 241 is displaced counterclockwise. In this case, it can also be said that the sliding portion 141 slides on the inclined surface 241 from the upstream end to the downstream end of the inclined surface 241. When the first base 10 rotates relative to the second base 20, the position of the inclined surface 241 of the second base 20 is fixed, and the sliding portion 141 of the first base 10 is displaced clockwise. The sliding portion 141 slides on the inclined surface 241 from the upstream end to the downstream end of the inclined surface 241. In a form in which the sliding portion 141 is provided on the first outer peripheral portion 13, the sliding portion 141 may have a ceiling that is substantially the same height as the top surface 121 of the containing portion 12 or a lower height than the top surface 121 of the containing portion 12 surface. It is avoided or suppressed that the sliding portion 141 becomes an obstacle to the magnetic adhesion of the first and second base portions 10 and 20.
於第1基部10及/或第2基部20之旋轉之至少初期階段(例如圖13及圖14所示之狀態)，包含部12之頂面121與第2基部20之對向面22不接觸。無法獲得藉由包含部12之頂面121與第2基部20之對向面22之接觸實現之旋轉穩定性，但容易獲得第1及第2基部10、20間之更強之磁性耦合。At least at the initial stage of the rotation of the first base 10 and/or the second base 20 (for example, the state shown in FIGS. 13 and 14 ), the top surface 121 of the containing portion 12 does not contact the opposing surface 22 of the second base 20 . The rotational stability achieved by the contact between the top surface 121 of the included portion 12 and the opposing surface 22 of the second base 20 cannot be obtained, but it is easy to obtain stronger magnetic coupling between the first and second bases 10, 20.
參照圖13至圖16，對第1構件7與第2構件8結合之過程進行說明。若第1基部10之包含部12所包含之磁鐵或磁性體11與第2基部20之配置於對向面22之正下方之磁鐵或磁性體21磁性耦合，則磁鐵或磁性體21由磁鐵或磁性體11吸引，第2基部20朝向第1基部10移動。於在第1基部10設置永久磁鐵之形態中，永久磁鐵11之自N極朝向S極之磁力線沿著上下方向透過第1外周部13，且具有沿著包含部12之側面122延伸之線段(參照圖8之箭頭ML1)。因此，並不限於在上下方向上鄰接於永久磁鐵11配置磁鐵或磁性體21之狀態，於在左右方向上鄰接於永久磁鐵11配置磁鐵或磁性體21之狀態下產生兩者之磁性耦合。為了便於說明，設為第2基部20朝向第1基部10向上方移動。The process of joining the first member 7 and the second member 8 will be described with reference to FIGS. 13 to 16. If the magnet or magnetic body 11 included in the containing portion 12 of the first base 10 is magnetically coupled with the magnet or magnetic body 21 of the second base 20 disposed directly under the opposing surface 22, the magnet or magnetic body 21 is composed of the magnet or the magnetic body 21 The magnetic body 11 is attracted, and the second base 20 moves toward the first base 10. In the form in which the permanent magnet is provided in the first base 10, the magnetic force line of the permanent magnet 11 from the N pole to the S pole passes through the first outer peripheral portion 13 in the up-down direction, and has a line segment extending along the side surface 122 of the containing portion 12 Refer to arrow ML1 in FIG. 8). Therefore, it is not limited to the state where the magnet or the magnetic body 21 is arranged adjacent to the permanent magnet 11 in the up-down direction, and the magnetic coupling of the two is generated when the magnet or the magnetic body 21 is arranged adjacent to the permanent magnet 11 in the left-right direction. For convenience of explanation, it is assumed that the second base 20 moves upward toward the first base 10.
若第2基部20朝向第1基部10向上方移動，則第1基部10與第2基部20重合。此時，第1基部10之第1接觸部14與第2基部20之第2接觸部24接觸，又，第1基部10之第3接觸部34與第2基部20之第4接觸部44接觸。即，第1基部10與第2基部20於2個部位接觸。第2基部20採取相對於第1基部10根據至少第1及第2接觸部14、24之接觸以及第3及第4接觸部34、44之接觸而傾斜之姿勢。由於第2接觸部24為傾斜面241，第1接觸部14為滑動部141，故而根據於第1及第2基部10、20間產生之磁吸引力，滑動部141開始於傾斜面241下降。於滑動部141之位置固定之前提下，傾斜面241開始沿著逆時針方向位移。作為第4接觸部44之滑動部開始於作為第3接觸部34之滑動面上滑動。對應於滑動部141於傾斜面241下降，第1基部10與第2基部20之間隔減少。尤其是，第1基部10之後端部10R與第2基部20之間隔、或者第2基部20之後端部20R與第1基部10之間隔減少。於第3接觸部34與第4接觸部44之接觸點，第1基部10與第2基部20之間隔保持為零。When the second base 20 moves upward toward the first base 10, the first base 10 and the second base 20 overlap. At this time, the first contact portion 14 of the first base portion 10 is in contact with the second contact portion 24 of the second base portion 20, and the third contact portion 34 of the first base portion 10 is in contact with the fourth contact portion 44 of the second base portion 20 . That is, the first base 10 and the second base 20 are in contact at two locations. The second base 20 takes a posture inclined relative to the first base 10 based on at least the contact of the first and second contact portions 14 and 24 and the contact of the third and fourth contact portions 34 and 44. Since the second contact portion 24 is the inclined surface 241 and the first contact portion 14 is the sliding portion 141, the sliding portion 141 starts to descend from the inclined surface 241 based on the magnetic attraction generated between the first and second base portions 10 and 20. Before the position of the sliding portion 141 is fixed, the inclined surface 241 starts to move counterclockwise. The sliding portion as the fourth contact portion 44 starts to slide on the sliding surface as the third contact portion 34. As the sliding portion 141 descends on the inclined surface 241, the distance between the first base 10 and the second base 20 decreases. In particular, the distance between the end 10R after the first base 10 and the second base 20 or the distance between the end 20R after the second base 20 and the first base 10 decreases. At the contact point between the third contact portion 34 and the fourth contact portion 44, the distance between the first base 10 and the second base 20 is kept at zero.
根據第2基部20相對於第1基部10之旋轉之進展(滑動部141於傾斜面241下降之進展)，第2輔助接觸部62之頂面902、906與第1輔助接觸部61之頂面917、913接觸。藉此，第1基部10與第2基部20於4個部位接觸。根據第2基部20相對於第1基部10之旋轉之進一步之進展(滑動部141於傾斜面241下降之進一步之進展)，第2輔助接觸部62之頂面902、906與傾斜面903、907之間之邊緣93、94和第1輔助接觸部61之頂面917、913與傾斜面918、914之間之邊緣91、92產生干涉。與於磁鐵11、21間產生之磁吸引力對應之第1基部10及/或第2基部20之旋轉力獲勝，從而第1基部10及/或第2基部20之旋轉持續。根據第2基部20相對於第1基部10之旋轉之進一步之進展(滑動部141於傾斜面241下降之進一步之進展)，第2輔助接觸部62之頂面902、906與鄰接於第1輔助接觸部61之傾斜面918、914之平坦面919、915接觸。According to the progress of the rotation of the second base 20 relative to the first base 10 (the progress of the sliding portion 141 descending on the inclined surface 241), the top surfaces 902, 906 of the second auxiliary contact portion 62 and the top surface of the first auxiliary contact portion 61 917, 913 contact. As a result, the first base 10 and the second base 20 are in contact at four locations. According to the further progress of the rotation of the second base 20 relative to the first base 10 (the further progress of the sliding portion 141 descending on the inclined surface 241), the top surfaces 902, 906 and the inclined surfaces 903, 907 of the second auxiliary contact portion 62 The edges 93, 94 therebetween and the edges 91, 92 between the top surfaces 917, 913 of the first auxiliary contact portion 61 and the inclined surfaces 918, 914 interfere. The rotation force of the first base 10 and/or the second base 20 corresponding to the magnetic attractive force generated between the magnets 11 and 21 wins, and the rotation of the first base 10 and/or the second base 20 continues. According to the further progress of the rotation of the second base 20 relative to the first base 10 (the further progress of the sliding portion 141 descending on the inclined surface 241), the top surfaces 902, 906 of the second auxiliary contact portion 62 are adjacent to the first auxiliary The flat surfaces 919 and 915 of the inclined surfaces 918 and 914 of the contact portion 61 are in contact.
亦可理解為：根據第2基部20相對於第1基部10之旋轉之進展(滑動部141於傾斜面241下降之進展)，第2輔助接觸部62越過第1輔助接觸部61。若滑件5前進，則插入部40完全插入至插入部31之接受部35，又，第1及第2鉤81、82相互卡合，從而拉鏈鏈齒部41卡合於左側之拉鏈鏈齒4(參照圖1)。It can also be understood that the second auxiliary contact portion 62 passes the first auxiliary contact portion 61 according to the progress of the rotation of the second base portion 20 relative to the first base portion 10 (the progress of the sliding portion 141 descending on the inclined surface 241 ). When the slider 5 advances, the insertion portion 40 is fully inserted into the receiving portion 35 of the insertion portion 31, and the first and second hooks 81 and 82 are engaged with each other, so that the fastener element 41 is engaged with the fastener element on the left 4 (refer to Figure 1).
於本說明書亦揭示有如下發明。藉由第2基部之傾斜姿勢，插入部之上下位移量局部地或整體地減少，從而促進插入部順利地插入至滑件內。
