The end surface of the rail side end portion 21a abuts against the insertion regulating surface 37, and determines the position of the outer tube 21 in the direction of the insertion shaft 32x. The rail-side end portion 21a is easily inserted into the insertion groove 36 by forming the funnel-shaped inner surface of the introduction groove portion 36c. The wire 15 is introduced into the pulley housing portion 31 from the insertion groove 36, and supports (winds) the steel on the outer circumferential surface of the guide pulley 17. Silk guide groove. In the state in which the rail-side end portion 21a of the outer tube 21 is attached to the tube insertion portion 32 outside the pulley bracket 30 (first to fifth figures), the wire 15 can advance and retreat to the outer tube 21, and the guide pulley 17 can be guided. Rotates as the wire 15 advances and retreats.
滑輪托架30係由合成樹脂等材質構成的成形品,且使用第八圖所示之金屬模(上模)45與金屬模(下模)46而成形。第八圖顯示滑輪托架30中形成外管插入部32之部分的金屬模構成。金屬模45與金屬模46可在沿著滑輪支撐軸19之軸線19x的方向改變彼此之間隔,且可接近至彼此之管制面47、48抵接的位置。另外,亦可採用將金屬模45與金屬模46之其中一方形成可移動的活動型,將另一方形成不移動之固定型的形態,或兩者皆形成可移動之活動型的形態。因為滑輪托架30之滑輪收容部31係在沿著滑輪支撐軸19之軸線19x的方向開放之凹部,所以可藉由在沿著軸線19x之方向(第八圖之上下方向)相對移動的金屬模45與金屬模46而形成。滑輪收容部31之收容部開口31a藉由設於金屬模45之突出部(省略圖示)而形成。 The pulley bracket 30 is a molded product made of a material such as synthetic resin, and is formed by using a metal mold (upper mold) 45 and a metal mold (lower mold) 46 shown in FIG. The eighth figure shows the configuration of the metal mold in the portion of the pulley bracket 30 where the outer tube insertion portion 32 is formed. The metal mold 45 and the metal mold 46 are changeable from each other in the direction along the axis 19x of the pulley support shaft 19, and are accessible to positions where the control faces 47, 48 of each other abut. Further, it is also possible to adopt a form in which one of the metal mold 45 and the metal mold 46 is movable, and the other is formed into a fixed type that does not move, or both of them form a movable movable type. Since the pulley accommodating portion 31 of the pulley bracket 30 is a recess opened in the direction along the axis 19x of the pulley support shaft 19, the metal can be relatively moved by the direction along the axis 19x (the lower direction in the eighth diagram). The mold 45 is formed with a metal mold 46. The accommodating portion opening 31a of the pulley accommodating portion 31 is formed by a protruding portion (not shown) provided in the mold 45.
與滑輪收容部31同樣地外管插入部32亦可僅以金屬模45與金屬模46形成。如第八圖所示,金屬模45與金屬模46具有彼此相對之凹部49、50。金屬模45具有從凹部49底部突出之突起51,金屬模46具有從凹部50底部突出之突起52。突起52形成具有從前端至指定深度凹設之中間凹部53的雙股形狀,可在中間凹部53內插入突起51。突起51之突出量比中間凹部53的深度小,在將突起51插入最深狀態(管制面47、48抵接之狀態)下,在突起51之前端與中間凹部53的底部之間形成間隙。滑輪托架30成形時,使金屬模45與金屬模46接近至管制面47與管制面48抵接時,藉由凹部49與凹部50之內面形成包含補強肋條42之外管插入部32的外面形狀。此外,突 起51藉由金屬模45與金屬模46之接近而插入中間凹部53內,組合突起51與突起52而形成管支撐溝部36b之內部空間。形成該插通溝36時,藉由突起51形成開口38,並藉由雙股形狀之突起52形成一對貫穿孔40。此外,藉由雙股形狀之突起52的前端附近形成一對止脫部39的內面,凹部49中藉由與各突起52之前端附近相對的區域形成一對止脫部39之外面。在管制面47與管制面48抵接狀態下,突起51之前端與中間凹部53的底部之間有間隙,並藉由該間隙而形成跨接部41。 Similarly to the pulley housing portion 31, the outer tube insertion portion 32 may be formed only by the metal mold 45 and the metal mold 46. As shown in the eighth figure, the metal mold 45 and the metal mold 46 have concave portions 49, 50 opposed to each other. The metal mold 45 has a projection 51 projecting from the bottom of the recess 49, and the metal mold 46 has a projection 52 projecting from the bottom of the recess 50. The projection 52 is formed in a double-strand shape having an intermediate recess 53 recessed from the front end to a predetermined depth, and the projection 51 can be inserted into the intermediate recess 53. The amount of protrusion of the protrusion 51 is smaller than the depth of the intermediate recess 53. When the protrusion 51 is inserted into the deepest state (the state in which the regulating surfaces 47, 48 abut), a gap is formed between the front end of the protrusion 51 and the bottom of the intermediate recess 53. When the pulley bracket 30 is formed, when the mold 45 and the mold 46 are brought close to the control surface 47 and the control surface 48, the concave portion 49 and the inner surface of the concave portion 50 form the tube insertion portion 32 including the reinforcing rib 42. Outer shape. In addition, The mold 51 is inserted into the intermediate recess 53 by the proximity of the metal mold 45 and the mold 46, and the projection 51 and the projection 52 are combined to form the internal space of the tube support groove portion 36b. When the insertion groove 36 is formed, the opening 38 is formed by the projection 51, and the pair of through holes 40 are formed by the double-shaped projection 52. Further, the inner faces of the pair of retaining portions 39 are formed in the vicinity of the front end of the double-shaped projections 52, and the outer faces of the pair of retaining portions 39 are formed in the recesses 49 by the regions facing the vicinity of the front ends of the respective projections 52. In a state in which the regulating surface 47 is in contact with the regulating surface 48, a gap is formed between the front end of the projection 51 and the bottom of the intermediate recess 53, and the bridging portion 41 is formed by the gap.
如此,對鄰接於開口38之止脫部39,藉由將在沿著軸線19x之方向相對的貫穿孔40設於外管插入部32,無須使用在插入軸32x方向移動之另外金屬模,藉由金屬模45與金屬模46即可形成包含在插入軸32x方向延伸之插通溝36的整個外管插入部32。藉此,可簡化滑輪托架30成形用之金屬模構造,包含滑輪托架30之窗玻璃開閉器10的生產性提高。 Thus, by providing the retaining portion 39 adjacent to the opening 38 with the through hole 40 opposed in the direction along the axis 19x to the outer tube insertion portion 32, it is not necessary to use another metal mold that moves in the direction of the insertion shaft 32x. The entire outer tube insertion portion 32 including the insertion groove 36 extending in the direction of the insertion shaft 32x can be formed by the metal mold 45 and the metal mold 46. Thereby, the metal mold structure for molding the pulley bracket 30 can be simplified, and the productivity of the window glass shutter 10 including the pulley bracket 30 can be improved.

The diameter of the wire 16 is smaller than the width of the opening 68 through which the wire 16 can be inserted or withdrawn through the opening 68.
外管插入部62中,在沿著鼓輪支撐軸65之軸線65x方向與一對止脫部69相對之位置形成有一對貫穿孔70,在一對貫穿孔70之間的周方向位置形成有連接插入管制面67與導入溝部66c之跨接部71。各貫穿孔70貫穿形成於沿著軸線65x之方向中與開口68相反側的壁部,跨接部71位於沿著軸線65x方向而與開口68相對。沿著軸線65x觀看各個貫穿孔70時的投影面積設定成與在軸線69x方向為相對關係之止脫部69的投影面積同等或比其大,從貫穿孔70側朝向止脫部69側(亦即從與第十圖相反側)觀看外管插入部62時,成為在各貫穿孔70外形之範圍內容納對應之止脫部69的位置關係。 In the outer tube insertion portion 62, a pair of through holes 70 are formed at positions facing the pair of retaining portions 69 in the direction of the axis 65x of the drum support shaft 65, and a circumferential position is formed between the pair of through holes 70. The insertion control surface 67 and the bridging portion 71 of the introduction groove portion 66c are connected. Each of the through holes 70 penetrates a wall portion formed on the opposite side of the opening 68 in the direction along the axis 65x, and the bridging portion 71 is opposed to the opening 68 in the direction along the axis 65x. The projected area when each of the through holes 70 is viewed along the axis 65x is set to be equal to or larger than the projected area of the retaining portion 69 in the opposing relationship of the axis 69x, and is directed from the through hole 70 side toward the retaining portion 69 side (also In other words, when the outer tube insertion portion 62 is viewed from the side opposite to the tenth view, the positional relationship of the retaining portion 69 corresponding to the outer shape of each of the through holes 70 is accommodated.
在外管插入部62之外面,於軸線方向以夾著貫穿孔70之位置關係突出形成有一對補強肋條72。各個補強肋條72在除了開口68之形成部分的區域形成在周方向包圍外管插入部62之形狀。 A pair of reinforcing ribs 72 are formed on the outer surface of the outer tube insertion portion 62 so as to protrude in the axial direction with the through hole 70 interposed therebetween. Each of the reinforcing ribs 72 is formed in a shape surrounding the outer tube insertion portion 62 in the circumferential direction except for the portion where the opening 68 is formed.
組合窗玻璃開閉器10時,從外管22之鼓輪側端部22b突出的鋼絲16通過開口68而插入外管插入部62之插通溝66內,並且將鼓輪側端部22b從導入溝部66c沿著插入軸62x插入插通溝36內。鼓輪側端部22b之端面抵接於插入管制面67,而決定外管22在插入軸62x方向之位置。鋼絲16從插通溝66通過鋼絲插通路60c導入鼓輪收容部60內,並捲繞於捲收鼓輪23之外 周面上的螺旋溝中。如此,在將外管22之鼓輪側端部22b安裝於鼓輪機架20之外管插入部62的狀態(第一圖至第三圖)下,鋼絲16可對外管22進退,鋼絲16對螺旋溝之捲繞量依捲收鼓輪23之旋轉而變化。對外管插入部61安裝外管21(鼓輪側端部21b)時,鋼絲15對捲收鼓輪23之捲繞亦同樣地進行。 When the glazing shutter 10 is assembled, the wire 16 protruding from the drum-side end portion 22b of the outer tube 22 is inserted into the insertion groove 66 of the outer tube insertion portion 62 through the opening 68, and the drum-side end portion 22b is introduced. The groove portion 66c is inserted into the insertion groove 36 along the insertion shaft 62x. The end surface of the drum-side end portion 22b abuts against the insertion regulating surface 67, and determines the position of the outer tube 22 in the direction of the insertion shaft 62x. The wire 16 is introduced into the drum housing portion 60 from the insertion groove 66 through the wire insertion passage 60c, and is wound around the winding drum 23 In the spiral groove on the circumference. Thus, in a state in which the drum-side end portion 22b of the outer tube 22 is attached to the tube insertion portion 62 outside the drum frame 20 (first to third figures), the wire 16 can be advanced and retracted from the outer tube 22, and the pair of wires 16 The amount of winding of the spiral groove varies depending on the rotation of the winding drum 23. When the outer tube 21 (the drum side end portion 21b) is attached to the outer tube insertion portion 61, the winding of the wire 15 to the winding drum 23 is also performed in the same manner.
鼓輪機架20中安裝馬達單元25。如第一圖至第三圖所示,馬達單元25具有馬達25a、齒輪盒25b及護蓋部25c。齒輪盒25b中內藏使馬達25a之輸出軸的旋轉減速而且傳達之減速齒輪列,經由減速齒輪列傳達馬達25a之旋轉驅動力的嵌合軸(省略圖示)從護蓋部25c突出。護蓋部25c覆蓋從鼓輪機架20之收容部開口60a至開口68的開口部分,從護蓋部25c突出之嵌合軸在鼓輪收容部60內與捲收鼓輪23(第十圖)嵌合,馬達25a之驅動力可傳達至捲收鼓輪23。 A motor unit 25 is mounted in the drum frame 20. As shown in the first to third figures, the motor unit 25 has a motor 25a, a gear case 25b, and a cover portion 25c. The gear box 25b has a reduction gear train that decelerates the rotation of the output shaft of the motor 25a, and a fitting shaft (not shown) that transmits the rotational driving force of the motor 25a via the reduction gear train protrudes from the cover portion 25c. The cover portion 25c covers the opening portion from the housing opening 60a of the drum frame 20 to the opening 68, and the fitting shaft protruding from the cover portion 25c is in the drum housing portion 60 and the winding drum 23 (10th drawing) The fitting force of the motor 25a can be transmitted to the winding drum 23.
鼓輪機架20係由合成樹脂等材質構成之成形品,且使用第十一圖所示之金屬模(上模)75與金屬模(下模)76而成形。金屬模75與金屬模76可在沿著鼓輪支撐軸65之軸線65x的方向使彼此之間隔變化,並可接近至彼此之管制面77、78抵接的位置。亦可採用將金屬模75與金屬模76之任何一方形成可移動之活動型,另一方形成不移動之固定型的形態,或兩者皆形成可移動之活動型的形態。因為鼓輪機架20之鼓輪收容部60係在沿著鼓輪支撐軸65之軸線65x方向開放的凹部,所以可藉由在沿著軸線65x之方向(第十一圖之上下方向)相對移動的金屬模75與金屬模76而形成。鼓輪收容部60之收容部開口60a藉由設於金屬模75的突出部(省略圖示)而形成。 The drum frame 20 is a molded product made of a material such as synthetic resin, and is formed by using a metal mold (upper mold) 75 and a metal mold (lower mold) 76 shown in FIG. The metal mold 75 and the metal mold 76 are spaced apart from each other in the direction along the axis 65x of the drum support shaft 65, and are close to positions where the control faces 77, 78 of each other abut. It is also possible to adopt a movable type in which one of the metal mold 75 and the metal mold 76 is formed, and the other form a fixed type which does not move, or both of which form a movable movable type. Since the drum housing portion 60 of the drum frame 20 is a recess opened in the direction of the axis 65x of the drum support shaft 65, it can be relatively moved in the direction along the axis 65x (the downward direction in the eleventh diagram). The metal mold 75 is formed with the metal mold 76. The accommodating portion opening 60a of the drum accommodating portion 60 is formed by a protruding portion (not shown) provided in the mold 75.
與鼓輪收容部60同樣地,外管插入部62亦可僅由金屬模75 與金屬模76形成。如第十一圖所示,金屬模75與金屬模76具有彼此相對之凹部79、80,金屬模75具有從凹部79之底部突出的突起81,金屬模76具有從凹部80底部突出之雙股形狀的突起82與凹設於其間之中間凹部83。突起81可插入中間凹部83,突起81之突出量比中間凹部83的深度小。鼓輪機架20成形時,使金屬模75與金屬模76接近至管制面77與管制面78抵接時,藉由凹部79與凹部80之內面形成包含補強肋條72之外管插入部62的外面形狀。此外,突起81藉由金屬模75與金屬模76之接近而插入中間凹部83內,藉由組合突起81與突起82而形成外管支撐溝部66b之內部空間。此時,藉由突起81形成開口68,並藉由雙股形狀之突起82形成一對貫穿孔70。此外,藉由雙股形狀之突起82的前端附近形成一對止脫部69的內面,藉由凹部79中與各突起82之前端附近相對的區域而形成一對止脫部69的外面。在管制面77與管制面78抵接狀態下,突起81之前端與中間凹部83的底部之間有間隙,並藉由該間隙形成跨接部71。第十一圖係顯示外管插入部62之成形,不過外管插入部61仍以同樣之金屬模構成(亦即金屬模75與金屬模76)而形成。 Similarly to the drum housing portion 60, the outer tube insertion portion 62 may be made only of the metal mold 75. Formed with a metal mold 76. As shown in the eleventh diagram, the metal mold 75 and the metal mold 76 have concave portions 79, 80 opposed to each other, the metal mold 75 has a projection 81 projecting from the bottom of the concave portion 79, and the metal mold 76 has a double strand protruding from the bottom of the concave portion 80. The shaped projections 82 are recessed between the intermediate recesses 83. The protrusion 81 can be inserted into the intermediate recess 83, and the protrusion 81 is protruded by a smaller amount than the intermediate recess 83. When the drum frame 20 is formed, when the metal mold 75 and the metal mold 76 are brought close to the control surface 77 and the control surface 78, the concave portion 79 and the inner surface of the concave portion 80 form the tube insertion portion 62 including the reinforcing rib 72. Outer shape. Further, the projection 81 is inserted into the intermediate recess 83 by the proximity of the metal mold 75 and the mold 76, and the inner space of the outer tube support groove portion 66b is formed by combining the projection 81 and the projection 82. At this time, the opening 68 is formed by the protrusion 81, and the pair of through holes 70 are formed by the double-shaped protrusion 82. Further, the inner faces of the pair of retaining portions 69 are formed in the vicinity of the front end of the double-shaped projections 82, and the outer faces of the pair of retaining portions 69 are formed by the regions of the recesses 79 opposed to the vicinity of the front ends of the respective projections 82. In a state where the regulating surface 77 is in contact with the regulating surface 78, there is a gap between the front end of the projection 81 and the bottom of the intermediate recess 83, and the bridging portion 71 is formed by the gap. The eleventh figure shows the formation of the outer tube insertion portion 62, but the outer tube insertion portion 61 is still formed by the same metal mold (i.e., the metal mold 75 and the metal mold 76).
如此,藉由將對鄰接於開口68之止脫部69在沿著軸線65x的方向相對之貫穿孔70設於外管插入部61、62,無須使用在插入軸61x、62x方向移動之另外金屬模,藉由金屬模75與金屬模76即可形成整個包含在插入軸61x、62x方向延伸之插通溝66的外管插入部61、62。藉此可簡化用於鼓輪機架20成形之金屬模構造,包含鼓輪機架20之窗玻璃開閉器10的生產性提高。 Thus, by providing the retaining portions 69 adjacent to the opening 68 in the outer tube insertion portions 61, 62 with the through holes 70 opposed in the direction along the axis 65x, it is not necessary to use another metal moving in the direction of the insertion shafts 61x, 62x. In the mold, the outer tube insertion portions 61, 62 including the insertion grooves 66 extending in the direction of the insertion shafts 61x, 62x are formed by the metal mold 75 and the metal mold 76. Thereby, the metal mold construction for forming the drum frame 20 can be simplified, and the productivity of the window glass shutter 10 including the drum frame 20 can be improved.
如第十二圖至第十六圖所示,鋼絲引導構件18具有:支撐從 外管22之軌道側端部22a延伸的鋼絲16之圓弧狀的鋼絲引導溝(引導溝)90;及可插入軌道側端部22a之外管插入部91。鋼絲引導溝90具有在窗玻璃開閉器10完成狀態(第一圖至第三圖)下概略朝向下方的開口92。 As shown in the twelfth to sixteenth drawings, the wire guiding member 18 has: a support from An arc-shaped wire guiding groove (guide groove) 90 of the wire 16 extending from the rail side end portion 22a of the outer tube 22; and a tube insertion portion 91 which is insertable beyond the rail side end portion 22a. The wire guiding groove 90 has an opening 92 that is generally downward in a state in which the window glass shutter 10 is completed (first to third figures).
鋼絲引導構件18中之外管插入部91的構成,與滑輪托架30中之外管插入部32或鼓輪機架20中之外管插入部61及外管插入部62相似。詳細而言,在外管插入部91內形成沿著軌道側端部22a之插入方向的插入軸91x(第十二圖)貫穿之插通溝93,插通溝93連通於鋼絲引導溝90。插通溝93具有:可插入外管22之軌道側端部22a的管支撐溝部93a;及隨著從管支撐溝部93a離開進入外管插入部91前端側而逐漸增大內徑的導入溝部93b。在鋼絲引導溝90與管支撐溝部93a之邊界的階差部分形成有插入管制面94(第十六圖)。外管22之軌道側端部22a從導入溝部93b側沿著插入軸91x插入管支撐溝部93a內,並藉由軌道側端部22a之端面抵接於插入管制面94,來管制外管22朝向插入方向過度移動(第一圖至第三圖所示之狀態)。 The outer tube insertion portion 91 of the wire guiding member 18 is similar to the outer tube insertion portion 32 or the outer tube insertion portion 62 of the outer tube insertion portion 32 or the drum frame 20 in the pulley bracket 30. Specifically, in the outer tube insertion portion 91, the insertion groove 93 through which the insertion shaft 91x (twelfth view) in the insertion direction of the rail side end portion 22a is inserted is formed, and the insertion groove 93 communicates with the wire guiding groove 90. The insertion groove 93 has a tube support groove portion 93a that can be inserted into the rail-side end portion 22a of the outer tube 22, and an introduction groove portion 93b that gradually increases the inner diameter as it goes away from the tube support groove portion 93a and enters the distal end side of the outer tube insertion portion 91. . An insertion regulating surface 94 is formed at a step portion of the boundary between the wire guiding groove 90 and the tube supporting groove portion 93a (16th drawing). The rail-side end portion 22a of the outer tube 22 is inserted into the tube support groove portion 93a along the insertion shaft 91x from the introduction groove portion 93b side, and the end surface of the rail-side end portion 22a abuts against the insertion regulating surface 94 to regulate the orientation of the outer tube 22. The insertion direction is excessively moved (the state shown in the first to third figures).
外管插入部91中,在整個從管支撐溝部93a至導入溝部93b之軸線方向形成有貫穿於外管22(軌道側端部22a)之徑方向(徑方向中之第一方向)的縫隙狀開口95。開口95連通於鋼絲引導溝90之開口92。在對應於管支撐溝部93a之範圍設有位於夾著開口95在周方向兩側相對的一對止脫部96。如第十七圖所示,開口95之寬度比外管22的直徑小,在管支撐溝部93a中插入外管22之軌道側端部22a的狀態下,藉由一對止脫部96管制外管22從開口95抽出(向第十七圖中之下方移動)。鋼絲16之直徑比開口95及開口92的寬度小,可使鋼絲16通過開口95與開口92而在插通溝93與鋼絲引導溝90中插入或抽出。 In the outer tube insertion portion 91, a slit shape penetrating the radial direction (the first direction in the radial direction) of the outer tube 22 (the rail-side end portion 22a) is formed in the axial direction from the tube support groove portion 93a to the introduction groove portion 93b. Opening 95. The opening 95 communicates with the opening 92 of the wire guiding groove 90. A pair of retaining portions 96 that are opposed to each other in the circumferential direction across the opening 95 are provided in a range corresponding to the tube supporting groove portion 93a. As shown in Fig. 17, the width of the opening 95 is smaller than the diameter of the outer tube 22, and is controlled by the pair of retaining portions 96 in a state where the rail-side end portion 22a of the outer tube 22 is inserted into the tube supporting groove portion 93a. The tube 22 is withdrawn from the opening 95 (moving downward in the seventeenth view). The diameter of the wire 16 is smaller than the width of the opening 95 and the opening 92, so that the wire 16 can be inserted or withdrawn through the opening 95 and the opening 92 in the insertion groove 93 and the wire guiding groove 90.
外管插入部91中,在對插入軸91x直交之徑方向(插入外管插入部91之外管22的軌道側端部22a之徑方向),並在與一對止脫部96相對之位置形成有一對貫穿孔97(第十五圖、第十七圖),並在一對貫穿孔97間之周方向位置形成有連接插入管制面94與導入溝部93b之跨接部98。各貫穿孔97在徑方向與開口95相反側之壁部(徑方向中位於第二方向之壁部)貫穿而形成,跨接部98位於在徑方向與開口95相對。在外管插入部91之徑方向觀看各個貫穿孔97時的投影面積,設定成與在徑方向有相對關係之止脫部96的投影面積相等或比其大,如第十五圖,從貫穿孔97側朝向止脫部96側觀看外管插入部91時,成為在各貫穿孔97之外形範圍內容納對應之止脫部96的位置關係。 The outer tube insertion portion 91 is in a radial direction orthogonal to the insertion shaft 91x (in the radial direction of the rail-side end portion 22a of the tube 22 other than the outer tube insertion portion 91), and is opposed to the pair of the stop portions 96. A pair of through holes 97 (fifteenth and seventeenth views) are formed, and a bridging portion 98 that connects the insertion regulating surface 94 and the introduction groove portion 93b is formed at a position in the circumferential direction between the pair of through holes 97. Each of the through holes 97 is formed to penetrate the wall portion on the opposite side to the opening 95 in the radial direction (the wall portion located in the second direction in the radial direction), and the bridging portion 98 is opposed to the opening 95 in the radial direction. The projected area when the respective through holes 97 are viewed in the radial direction of the outer tube insertion portion 91 is set to be equal to or larger than the projected area of the retaining portion 96 having a relative relationship with respect to the radial direction, as shown in the fifteenth figure, from the through hole. When the outer tube insertion portion 91 is viewed from the side of the 97-way retaining portion 96, the positional relationship of the retaining portion 96 corresponding to the outer diameter of each of the through holes 97 is defined.
在外管插入部91外面,於軸線方向不同位置突出形成有一對補強肋條99。各個補強肋條99在除去開口95及貫穿孔97之形成部分的區域形成在周方向包圍外管插入部91之形狀。 A pair of reinforcing ribs 99 are formed on the outer surface of the outer tube insertion portion 91 at different positions in the axial direction. Each of the reinforcing ribs 99 is formed in a shape that surrounds the outer tube insertion portion 91 in the circumferential direction in a region where the opening 95 and the through hole 97 are formed.
組合窗玻璃開閉器10時,將從外管22之軌道側端部22a突出的鋼絲16通過開口92與開口95插入鋼絲引導溝90與外管插入部91之插通溝93內,並且將軌道側端部22a從導入溝部93b沿著插入軸91x插入插通溝93內。軌道側端部22a之端面抵接於插入管制面94,決定外管22在插入軸91x方向之位置。可在鋼絲引導溝90中進退而支撐之鋼絲16,如第二圖所示沿著導軌11設置並連接於滑件座14。 When the glazing shutter 10 is assembled, the wire 16 projecting from the rail-side end portion 22a of the outer tube 22 is inserted into the insertion groove 93 of the wire guiding groove 90 and the outer tube insertion portion 91 through the opening 92 and the opening 95, and the rail is placed. The side end portion 22a is inserted into the insertion groove 93 from the introduction groove portion 93b along the insertion shaft 91x. The end surface of the rail side end portion 22a abuts against the insertion regulating surface 94, and determines the position of the outer tube 22 in the direction of the insertion shaft 91x. A wire 16 that can be advanced and retracted in the wire guiding groove 90 is disposed along the guide rail 11 and connected to the slider seat 14 as shown in the second figure.
鋼絲引導構件18係由合成樹脂等材質構成的成形品,且使用第十七圖所示之金屬模100與金屬模101而成形。金屬模100與金屬模101可在第十二圖、第十三圖、第十六圖及第十七圖中之上下方向使彼此之間隔 變化,亦可採用將金屬模100與金屬模101之任何一方形成可移動之活動型,另一方形成不移動之固定型的形態,或是兩者皆形成可移動之活動型的形態。 The wire guiding member 18 is a molded article made of a material such as synthetic resin, and is formed by using the metal mold 100 and the metal mold 101 shown in FIG. The metal mold 100 and the metal mold 101 can be spaced apart from each other in the upper and lower directions in the twelfth, thirteenth, sixteenth and seventeenthth drawings. The change may be performed by forming either of the metal mold 100 and the metal mold 101 into a movable movable type, the other forming a fixed type that does not move, or both of which form a movable movable type.
鋼絲引導構件18因為鋼絲引導溝90之開口92與外管插入部91之開口95及貫穿孔97皆為朝向金屬模100與金屬模101之相對移動方向而開放,所以無須使用在外管插入部91之插入軸91x方向移動的另外金屬模,僅以金屬模100與金屬模101即可形成。如第十七圖所示,金屬模100與金屬模101具有彼此相對之凹部102、103,金屬模100具有從凹部102之底部突出的突起104,金屬模101具有從凹部103之底部突出的雙股形狀之突起105與凹設於其間之中間凹部106。突起104可插入中間凹部106,突起104之突出量比中間凹部106的深度小。鋼絲引導構件18成形時,使金屬模100與金屬模101接近至彼此之管制面(省略圖示)抵接時,藉由凹部102與凹部103之內面形成包含補強肋條99之外管插入部91的外面形狀。此外,突起104插入中間凹部106內,藉由組合突起104與突起105而形成管支撐溝部93a之內部空間。此時藉由突起104形成開口95,並藉由雙股形狀之突起105形成一對貫穿孔97。此外,藉由雙股形狀之突起105的前端附近形成一對止脫部96之內面,並藉由凹部102中與各突起105之前端附近相對的區域形成一對止脫部96的外面。在使金屬模100與金屬模101最接近狀態下,突起104之前端與中間凹部106的底部之間有間隙,並藉由該間隙形成跨接部98。 The wire guiding member 18 is open to the opening 95 of the wire guiding groove 90 and the opening 95 and the through hole 97 of the outer tube insertion portion 91 toward the relative movement direction of the metal mold 100 and the metal mold 101, so that it is not necessary to use the outer tube insertion portion 91. The additional metal mold that is inserted in the direction of the insertion shaft 91x can be formed only by the metal mold 100 and the metal mold 101. As shown in Fig. 17, the metal mold 100 and the metal mold 101 have concave portions 102, 103 which are opposed to each other, and the metal mold 100 has projections 104 projecting from the bottom of the concave portion 102, and the metal mold 101 has a double projection from the bottom of the concave portion 103. The protrusions 105 of the strand shape and the intermediate recess 106 recessed therebetween. The protrusion 104 can be inserted into the intermediate recess 106, and the protrusion 104 protrudes less than the depth of the intermediate recess 106. When the wire guiding member 18 is formed, when the mold 100 and the mold 101 are brought into contact with each other (not shown), the concave portion 102 and the inner surface of the concave portion 103 are formed with the tube insertion portion including the reinforcing rib 99. The outer shape of 91. Further, the projection 104 is inserted into the intermediate recess 106, and the inner space of the tube supporting groove portion 93a is formed by combining the projection 104 and the projection 105. At this time, the opening 95 is formed by the protrusion 104, and a pair of through holes 97 are formed by the double-shaped protrusion 105. Further, the inner faces of the pair of retaining portions 96 are formed in the vicinity of the front end of the double-strand-shaped projections 105, and the outer faces of the pair of retaining portions 96 are formed by the regions of the recesses 102 facing the vicinity of the front ends of the respective projections 105. In the state in which the metal mold 100 is closest to the metal mold 101, there is a gap between the front end of the projection 104 and the bottom of the intermediate recess 106, and the bridging portion 98 is formed by the gap.
如此,藉由將位於對鄰接於開口95之止脫部96在外管22(軌道側端部22a)之徑方向相對的貫穿孔97設於外管插入部91中,無須使用在插入軸91x方向移動之另外金屬模,藉由金屬模100與金屬模101即可形成整 個包含在插入軸91x方向延伸之插通溝93的外管插入部91。藉此,可簡化鋼絲引導構件18用於成形之金屬模構造,包含鋼絲引導構件18之窗玻璃開閉器10的生產性提高。 By providing the through hole 97 in the radial direction of the outer tube 22 (the rail side end portion 22a) in the outer tube insertion portion 91 in the direction in which the retaining portion 96 adjacent to the opening 95 is opposed to the opening 95, it is not necessary to use the insertion shaft 91x. The other metal mold that moves can be formed by the metal mold 100 and the metal mold 101. The outer tube insertion portion 91 includes an insertion groove 93 extending in the direction of the insertion shaft 91x. Thereby, the metal mold structure for forming the wire guiding member 18 can be simplified, and the productivity of the window glass shutter 10 including the wire guiding member 18 can be improved.
