（第一の実施形態）
以下、この発明を具体化した第一の実施形態を図面に従って説明する。図１及び図２に示すたくし上げカーテンは、ヘッドボックス１の前面から生地２が吊下支持されている。生地２の上端は、例えば面ファスナーでヘッドボックス１の前面に接着されている。 (First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The fabric curtain 2 shown in FIGS. 1 and 2 has a fabric 2 suspended from the front surface of the head box 1. The upper end of the fabric 2 is bonded to the front surface of the head box 1 with a hook-and-loop fastener, for example.

前記生地２には、複数本の棒状のサポート部材３が水平方向に等間隔に挿通されて生地２の平面性が確保されている。また、前記生地２の下端部には、ボトムレール４が挿通されている。   A plurality of rod-like support members 3 are inserted into the dough 2 at equal intervals in the horizontal direction to ensure the flatness of the dough 2. A bottom rail 4 is inserted through the lower end of the fabric 2.

前記ヘッドボックス１から複数本の昇降コード５が垂下されるとともに、その昇降コード５の上端部は前記ヘッドボックス１内に回転可能に支持された巻取軸６に巻着されている。   A plurality of lifting / lowering cords 5 are suspended from the head box 1, and the upper ends of the lifting / lowering cords 5 are wound around a winding shaft 6 that is rotatably supported in the head box 1.

前記巻取軸６には駆動軸７が相対回転不能に挿通されている。そして、駆動軸７を介して前記巻取軸６が回転されると、昇降コード５が巻取軸６に巻き取られ、あるいは巻取軸６から巻戻される。   A drive shaft 7 is inserted into the winding shaft 6 so as not to be relatively rotatable. When the winding shaft 6 is rotated via the drive shaft 7, the lifting / lowering cord 5 is wound around the winding shaft 6 or unwound from the winding shaft 6.

前記ヘッドボックス１の一端にはギヤボックス８が取着されるとともに、そのギヤボックス８の出力軸に前記駆動軸７の端部が嵌着されている。また、ギヤボックス８の入力軸にはプーリー９が嵌着され、そのプーリー９にボールチェーン１０が掛装されている。   A gear box 8 is attached to one end of the head box 1, and an end of the drive shaft 7 is fitted to the output shaft of the gear box 8. A pulley 9 is fitted on the input shaft of the gear box 8, and a ball chain 10 is hooked on the pulley 9.

そして、ボールチェーン１０を操作してプーリー９を回転させることにより、ギヤボックス８及び駆動軸７を介して巻取軸６が回転されるようになっている。
前記昇降コード５の垂下位置において、前記生地２の背面には複数のガイド部材１２が上下方向に等間隔に縫着されている。前記ヘッドボックス１から垂下される昇降コード５は前記ガイド部材１２に挿通されるとともに、その昇降コード５の下端にはコードキャッチ１１が取着されている。そして、コードキャッチ１１が生地２の下端部に取着された取付リング２１に取着されている。 Then, the winding shaft 6 is rotated via the gear box 8 and the drive shaft 7 by operating the ball chain 10 to rotate the pulley 9.
A plurality of guide members 12 are sewn on the back surface of the fabric 2 at equal intervals in the vertical direction at the hanging position of the lifting cord 5. The lifting / lowering cord 5 suspended from the head box 1 is inserted into the guide member 12, and a cord catch 11 is attached to the lower end of the lifting / lowering cord 5. The cord catch 11 is attached to an attachment ring 21 attached to the lower end of the fabric 2.

従って、昇降コード５が巻取軸６に巻き取られると、コードキャッチ１１が引き上げられてコードキャッチ１１のフック部１４より下方に吊下支持される生地２及びボトムレール４が引き上げられるとともに、コードキャッチ１１のコード受け部１３でガイド部材１２が順次押し上げられて、生地２が順次たくし上げられる。また、昇降コード５が巻取軸６から巻戻されると、生地２の下端部が下降して、たくし上げられた生地２がヘッドボックス１から吊下支持される状態に復帰する。   Therefore, when the lifting / lowering cord 5 is wound around the winding shaft 6, the cord catch 11 is pulled up, and the fabric 2 and the bottom rail 4 that are suspended below the hook portion 14 of the cord catch 11 are lifted, and the cord The guide member 12 is sequentially pushed up by the cord receiving portion 13 of the catch 11, and the fabric 2 is sequentially pushed up. When the lifting / lowering cord 5 is unwound from the take-up shaft 6, the lower end portion of the fabric 2 is lowered, and the fabric 2 that has been lifted is returned to the state of being supported by being suspended from the head box 1.

次に、前記コードキャッチ１１及びガイド部材１２の具体的構成について説明する。
図３に示すように、前記コードキャッチ１１は合成樹脂で成形されたコード受け部１３とフック部（第一のベース部材）１４とで構成される。コード受け部１３の中間部には、昇降コード５の下端部を掛止めするための掛止め部１５が形成されている。掛止め部１５の上方には昇降コード５を挿通するための挿通溝１６が形成されている。そして、前記掛止め部１５に掛止めされた昇降コード５は、挿通溝１６を経て上方へ案内される。 Next, specific configurations of the cord catch 11 and the guide member 12 will be described.
As shown in FIG. 3, the cord catch 11 includes a cord receiving portion 13 and a hook portion (first base member) 14 formed of synthetic resin. A latching portion 15 for latching the lower end portion of the lifting / lowering cord 5 is formed at an intermediate portion of the cord receiving portion 13. An insertion groove 16 for inserting the elevating cord 5 is formed above the latching portion 15. The lifting / lowering cord 5 hooked on the hooking portion 15 is guided upward through the insertion groove 16.

前記コード受け部１３の下端部には軸部１３ａが形成されるとともに、その軸部１３ａの外周面には周方向に突条１７が形成されている。
前記フック部１４は、その下部に前記取付リング２１を挿入して保持可能としたフック１８が形成されている。また、フック部１４の上端部には前記コード受け部１３の軸部１３ａを嵌合可能とした嵌合凹部１９が形成されるとともに、その嵌合凹部１９の内周面には、図４に示すように、前記突条１７を嵌合可能とした凹条２０が形成されている。 A shaft portion 13a is formed at the lower end portion of the cord receiving portion 13, and a ridge 17 is formed in the circumferential direction on the outer peripheral surface of the shaft portion 13a.
The hook portion 14 is formed with a hook 18 which can be held by inserting the mounting ring 21 at a lower portion thereof. A fitting recess 19 is formed at the upper end of the hook portion 14 so that the shaft portion 13a of the cord receiving portion 13 can be fitted, and the inner peripheral surface of the fitting recess 19 is shown in FIG. As shown, a recess 20 is formed that allows the protrusion 17 to be fitted.

そして、コード受け部１３の軸部１３ａをフック部１４の嵌合凹部１９に挿入すると、突条１７が凹条２０に弾性的に嵌合して、コード受け部１３とフック部１４が連結されるようになっている。   When the shaft portion 13a of the cord receiving portion 13 is inserted into the fitting concave portion 19 of the hook portion 14, the protrusion 17 is elastically fitted to the concave portion 20, and the cord receiving portion 13 and the hook portion 14 are connected. It has become so.

このように構成されたコードキャッチ１１のコード受け部１３に昇降コード５の下端部を取着し、さらにフック部１４を取付リング２１に取着すると、生地２の下端部が昇降コード５で吊下支持されるようになっている。   When the lower end portion of the lifting / lowering cord 5 is attached to the cord receiving portion 13 of the cord catch 11 configured as described above and the hook portion 14 is further attached to the attachment ring 21, the lower end portion of the fabric 2 is suspended by the lifting / lowering cord 5. Underneath is to be supported.

また、コード受け部１３とフック部１４との嵌合力は、取付リング２１より下方の生地２及びボトムレール４の重量に基づく引張り力では外れない嵌合力が確保され、当該引張り力を超える引張り力ではコード受け部１３がフック部１４から外れるようになっている。なお、コード受け部１３がフック部１４から外れる引張り力は、生地２及びボトムレール４の重量に基づく引張り力より大きな引張り力としてもよく、生地２及びボトムレール４の全重量に基づく引張り力を最大とする範囲で外れるようにしてもよい。   Further, the fitting force between the cord receiving portion 13 and the hook portion 14 is ensured to be a fitting force that cannot be removed by a tensile force based on the weight of the fabric 2 and the bottom rail 4 below the attachment ring 21, and the tensile force exceeding the tensile force. Then, the cord receiving part 13 comes off from the hook part 14. The tensile force at which the cord receiving portion 13 is detached from the hook portion 14 may be a tensile force larger than the tensile force based on the weight of the fabric 2 and the bottom rail 4, and the tensile force based on the total weight of the fabric 2 and the bottom rail 4 may be used. You may make it remove | deviate in the range made into the maximum.

前記ガイド部材１２は、図５に示すように、ベース部材（第二のベース部材）２２とコード保持部材２３とで構成される。ベース部材２２とコード保持部材２３とはともに合成樹脂で成形される。   As shown in FIG. 5, the guide member 12 includes a base member (second base member) 22 and a cord holding member 23. Both the base member 22 and the cord holding member 23 are formed of synthetic resin.

前記ベース部材２２の基端部２４には長円状の透孔２５が形成されるとともに、その透孔２５の一方は僅かな開口幅で開口されている。そして、図６に示すように、基端部２４が透孔２５を使用して生地２に縫着されている。   An oblong through hole 25 is formed in the base end portion 24 of the base member 22, and one of the through holes 25 is opened with a slight opening width. Then, as shown in FIG. 6, the base end portion 24 is sewn to the fabric 2 using the through hole 25.

前記ベース部材２２の先端部には丸軸部２６が形成されるとともに、その丸軸部２６の中間部にはその両側部より径の小さい縮径部２７が形成されている。
前記コード保持部材２３の基端部２８は、前記ベース部材２２の基端部２４と同様な形状に形成されるとともに、その透孔２９に前記昇降コード５が挿通されている。 A round shaft portion 26 is formed at the distal end portion of the base member 22, and a reduced diameter portion 27 having a smaller diameter than both side portions is formed at an intermediate portion of the round shaft portion 26.
The base end portion 28 of the cord holding member 23 is formed in the same shape as the base end portion 24 of the base member 22, and the elevating cord 5 is inserted into the through hole 29.

前記コード保持部材２３の先端部には、先端側を一部開口した環状の嵌合部３０が形成されている。そして、図６に示すように、その嵌合部３０内に前記ベース部材２２の縮径部２７を弾性的に嵌合可能であるとともに、所定値以上の引張り力により縮径部２７が嵌合部３０から外れるようになっている。この所定値は、通常の操作時に昇降コード５により作用する引っ張り力を超える値に設定されている。   An annular fitting portion 30 that is partially open at the distal end side is formed at the distal end portion of the cord holding member 23. As shown in FIG. 6, the reduced diameter portion 27 of the base member 22 can be elastically fitted into the fitting portion 30 and the reduced diameter portion 27 is fitted by a tensile force of a predetermined value or more. It comes off from the part 30. This predetermined value is set to a value that exceeds the tensile force acting by the lifting / lowering cord 5 during normal operation.

また、嵌合部３０に対し縮径部２７が嵌合するので、嵌合時には丸軸部２６が嵌合部３０に対し軸方向に移動不能に保持される。
次に、上記のように構成されたたくし上げカーテンの昇降装置の動作を説明する。 Further, since the reduced diameter portion 27 is fitted to the fitting portion 30, the round shaft portion 26 is held immovably in the axial direction with respect to the fitting portion 30 during fitting.
Next, the operation of the lifting curtain lifting / lowering device configured as described above will be described.

ボールチェーン１０を操作して、巻取軸６を昇降コード５の巻取り方向に回転させると、昇降コード５が巻取軸６に巻き取られる。すると、巻取軸６から垂下される昇降コード５がガイド部材１２に案内されながら上方へ移動して、コードキャッチ１１が引き上げられる。この結果、生地２が下端部からたくし上げられる。   When the winding shaft 6 is rotated in the winding direction of the lifting / lowering cord 5 by operating the ball chain 10, the lifting / lowering cord 5 is wound around the winding shaft 6. Then, the lifting / lowering cord 5 suspended from the winding shaft 6 moves upward while being guided by the guide member 12, and the cord catch 11 is pulled up. As a result, the fabric 2 is pulled up from the lower end.

このとき、コードキャッチ１１のコード受け部１３でガイド部材１２を押し上げることにより生地２がたくし上げられるので、コード受け部１３とフック部１４との間には、取付リング２１より下方の生地２及びボトムレール４の重量のみが作用している。   At this time, since the cloth 2 is lifted by pushing up the guide member 12 by the cord receiving portion 13 of the cord catch 11, the cloth 2 below the attachment ring 21 and the cord 2 between the cord receiving portion 13 and the hook portion 14 and Only the weight of the bottom rail 4 is acting.

一方、巻取軸６を昇降コード５の巻戻し方向に回転させると、昇降コード５が巻取軸６から巻き戻される。すると、昇降コード５がガイド部材１２に案内されながら下方へ移動して、コードキャッチ１１が下降する。この結果、生地２の下端部が下降して、たくし上げられた生地２がヘッドボックス１から吊下支持される状態に復帰する。   On the other hand, when the winding shaft 6 is rotated in the rewinding direction of the lifting / lowering cord 5, the lifting / lowering cord 5 is unwound from the winding shaft 6. Then, the lifting / lowering cord 5 moves downward while being guided by the guide member 12, and the cord catch 11 is lowered. As a result, the lower end portion of the fabric 2 is lowered, and the fabric 2 that has been raised is returned to the state of being supported by being suspended from the head box 1.

例えば生地２が下限近傍まで下降している状態で、居住者が生地２の背面側を移動するような場合に、昇降コード５が居住者に引っかかると、図７に示すように、昇降コード５に作用する引張り力により、コードキャッチ１１のコード受け部１３とフック部１４の嵌合が外れる。同時に、ガイド部材１２のベース部材２２とコード保持部材２３との嵌合が外れたり、あるいはコードキャッチ１１に先立って外れることもある。すると、居住者が昇降コード５に引っ掛かっても、その挙動が妨げられることはない。   For example, when the occupant moves on the back side of the fabric 2 while the fabric 2 is lowered to the vicinity of the lower limit, if the elevating cord 5 is caught by the occupant, as shown in FIG. The cord receiving portion 13 and the hook portion 14 of the cord catch 11 are disengaged due to the tensile force acting on the cord catch 11. At the same time, the base member 22 and the cord holding member 23 of the guide member 12 may be disengaged or may be detached prior to the cord catch 11. Then, even if a resident is caught in the raising / lowering cord 5, the behavior is not disturbed.

(Third embodiment)
10 and 11 show a third embodiment. This embodiment shows another embodiment of a cord catch for a tuck curtain.

コードキャッチ４１は、合成樹脂で成形されたフック部４２とコード受け部４３とで構成される。フック部４２は、その下端部が取付リング２１を介して生地２に取着されている。   The cord catch 41 includes a hook portion 42 and a cord receiving portion 43 that are formed of a synthetic resin. The lower end of the hook portion 42 is attached to the fabric 2 via the attachment ring 21.

前記フック部４２の上部は、上方を開口した箱型に形成され、その両側辺の上部には互いに近づく方向に斜めに延設された係止片４４が形成されている。
前記コード受け部４３はＵ字状に屈曲された弾性片４５の基端部に、昇降コード５を挿通可能とした挿通孔４６が形成されている。そして、昇降コード５の下端部が弾性片４５の基端側から挿通孔４６に挿通され、昇降コード５の下端に形成された結び目４７により、コード受け部４３が昇降コード５の下端に取着されている。 The upper portion of the hook portion 42 is formed in a box shape having an upper opening, and locking pieces 44 extending obliquely in a direction approaching each other are formed on upper portions of both sides.
In the cord receiving portion 43, an insertion hole 46 through which the elevating cord 5 can be inserted is formed at the base end portion of the elastic piece 45 bent in a U-shape. The lower end portion of the lifting / lowering cord 5 is inserted into the insertion hole 46 from the proximal end side of the elastic piece 45, and the cord receiving portion 43 is attached to the lower end of the lifting / lowering cord 5 by a knot 47 formed at the lower end of the lifting / lowering cord 5. Has been.

前記弾性片４５の先端部はともに拡幅されて係止軸部４８が形成されている。そして、係止軸部４８が互いに近づくように弾性片４５を撓ませて、係止軸部４８を係止片４４間の嵌合凹部に挿入すると、弾性片４５の撓みが解除された状態で、係止軸部４８が係止片４４間に保持されるようになっている。また、前記弾性片４５間には、金属性のボール４９が上下動可能に保持されている。   Both ends of the elastic pieces 45 are widened to form locking shafts 48. Then, when the elastic piece 45 is bent so that the locking shaft portion 48 approaches each other and the locking shaft portion 48 is inserted into the fitting recess between the locking pieces 44, the elastic piece 45 is released from being bent. The locking shaft portion 48 is held between the locking pieces 44. A metal ball 49 is held between the elastic pieces 45 so as to be movable up and down.

このように構成されたコードキャッチ４１では、昇降コード５でコード受け部４３が吊下支持されている通常時には、図１０に示すように、ボール４９が係止軸部４８上に位置している。   In the cord catch 41 configured as described above, the ball 49 is positioned on the locking shaft portion 48 as shown in FIG. 10 when the cord receiving portion 43 is suspended and supported by the lifting / lowering cord 5. .

この状態では、係止軸部４８が互いに近づく方向への弾性片４５の撓みがボール４９により阻止されるため、係止軸部４８が係止片４４間に保持されて、フック部４２がコード受け部４３に吊下支持される。従って、昇降コード５が昇降されると、コード受け部４３及びフック部４２が一体に昇降されて、生地２が昇降される。   In this state, the elastic pieces 45 are prevented from being bent in the direction in which the locking shaft portions 48 approach each other, so that the locking shaft portions 48 are held between the locking pieces 44 and the hook portions 42 are cords. Suspended and supported by the receiving portion 43. Therefore, when the raising / lowering cord 5 is raised / lowered, the cord receiving portion 43 and the hook portion 42 are integrally raised / lowered, and the fabric 2 is raised / lowered.

一方、昇降コード５に居住者等が引っ掛かり、ヘッドボックス内のストッパーが滑って図１１に示すようにコード受け部４３が下方へ引っ張られると、コード受け部４３が上下方向に逆転することからボール４９が弾性片４５間を下方へ移動する。   On the other hand, if a resident or the like is caught on the lifting / lowering cord 5 and the stopper in the head box slips and the cord receiving portion 43 is pulled downward as shown in FIG. 49 moves downward between the elastic pieces 45.

すると、弾性片４５は係止軸部４８が互いに近づく方向に撓むことが可能となるため、係止軸部４８が係止片４４から外れて、コード受け部４３がフック部４２から離脱する。
この結果、昇降コード５と生地２の接続が外れるため、昇降コード５と居住者等との引っ掛かりを解除することができる。 Then, the elastic piece 45 can be bent in the direction in which the locking shaft portion 48 approaches each other, so that the locking shaft portion 48 is detached from the locking piece 44 and the cord receiving portion 43 is detached from the hook portion 42. .
As a result, since the connection between the lifting / lowering cord 5 and the fabric 2 is released, the hooking between the lifting / lowering cord 5 and a resident can be released.

また、コード受け部４３とフック部４２との嵌合が外れた後には、コード受け部４３を上下方向に逆転させた状態で係止軸部４８をフック部４２との係止片４４間に再度嵌合すれば、昇降コード５の下端を生地２の下端部に容易に取着することができる。   In addition, after the cord receiving portion 43 and the hook portion 42 are disengaged, the locking shaft portion 48 is placed between the locking pieces 44 with the hook portion 42 in a state where the cord receiving portion 43 is reversed in the vertical direction. If it is fitted again, the lower end of the lifting / lowering cord 5 can be easily attached to the lower end of the fabric 2.

従って、この実施形態のコードキャッチ４１でも、第一の実施形態のコードキャッチ１１と同様な作用効果を得ることができる。
