Description

本発明は、窓枠など取り付けられるロールスクリーン、ブラインドなどの日射遮蔽装置の遮蔽部材を昇降する操作コードの操作時以外のときに衝撃牽引力が作用したときに簡単に分離可能な安全機構に関する。   The present invention relates to a safety mechanism that can be easily separated when an impact traction force is applied at a time other than the operation of an operation cord that lifts and lowers a shielding member of a solar radiation shielding device such as a roll screen attached to a window frame or a blind.
従来、建物の窓などに取り付ける遮光用のベネシャンブラインド、ローマンシェード、ロールスクリーンにおいて、日射遮蔽を操作するためのこれら遮蔽部材を昇降する操作コードを操作して開閉している。この操作コードはロールスクリーン等を昇降するためのヘッドボックスの回転軸を回転する無端コードが使用されている。このコードは無端状態で所定の長さを備えている。そのため回転軸を配置したヘッドケースから常時垂れ下げられている遮蔽部材の最低位置までたれ下げられているために、子供などがカーテン内に隠れて遊んでいるときに操作コードに捲きもまれることがあり危険であった。このような安全性を考慮して、操作コードに無理な力が負荷されたときに操作コードが途中から分離されるように工夫することが提案されている。
例えば、特開平09−189180号公報、特開平2003−184456号公報、特開2006−70448号公報などが知られている。
2. Description of the Related Art Conventionally, in a light shielding Venetian blind, a roman shade, and a roll screen that are attached to a building window or the like, an operation code for raising and lowering these shielding members for operating solar shading is operated to open and close. As the operation cord, an endless cord for rotating a rotation axis of a head box for raising and lowering a roll screen or the like is used. The cord is endless and has a predetermined length. For this reason, since the head case with the rotating shaft is hung down to the lowest position of the shielding member that is always hanging down, the operation code may be trapped when a child is hiding in the curtain and playing. There was a danger. In consideration of such safety, it has been proposed to devise so that the operation code is separated from the middle when an excessive force is applied to the operation code.
For example, JP-A 09-189180, JP-A 2003-184456, JP-A 2006-70448, and the like are known.

本発明の操作コードの安全機構は、請求項1に係る発明によれば、遮蔽部材であるスクリーンなどの生地を下降状態から引き上げるときは5.5Kg以下の力で操作コードを牽引するから嵌挿部材と操作コードの継部とが分離されることがない。これと逆にローマンシェード、ロールスクリーン、カーテンなどの生地が上昇位置にあるとき、すなわち、嵌挿部材が下側で結合部材が上側に配置されているとき、操作コード、ボールチェーンなどに2.5〜3.2Kgの衝撃力が加わった場合は簡易に嵌挿部材の係合部が結合部材の外筒から抜け落ちることになるので(子供などが操作コードに絡まれた状態で簡易に分離される)、非常に安全である。また、操作コードやボールチェーンを操作するときには支障をきたすことなく(操作コードの継部や連結部が分離されることなく)、構造機構が簡易であり、従来の合成樹脂などの係着溝などを必要としないから、構造が簡易に製造することができる。   According to the first aspect of the safety mechanism of the operation cord of the present invention, the operation cord is pulled with a force of 5.5 kg or less when the cloth such as the screen as the shielding member is pulled up from the lowered state. The member and the joint portion of the operation cord are not separated. On the contrary, when a cloth such as a roman shade, a roll screen, or a curtain is in the raised position, that is, when the fitting member is disposed on the lower side and the coupling member is disposed on the upper side, the operation cord, the ball chain, etc. When an impact force of 5 to 3.2 kg is applied, the engaging portion of the insertion member is easily detached from the outer cylinder of the coupling member (the child or the like is easily separated while being entangled with the operation cord). It is very safe. In addition, there is no hindrance when operating the operation cord and the ball chain (the operation cord joint and connection portion are not separated), the structure mechanism is simple, and the conventional engagement groove of synthetic resin, etc. Therefore, the structure can be easily manufactured.
特に、布地が降下状態のときに操作コード(ボールチェーン)を牽引して上昇させるときは操作コードを操作しても分離することがない。強力に牽引したときは操作コードの継部が嵌合部から容易に抜けることになる。   In particular, when the operation cord (ball chain) is pulled and raised when the fabric is in the descending state, it is not separated even if the operation cord is operated. When pulled strongly, the joint portion of the operation cord can be easily removed from the fitting portion.

本発明に係る日射遮蔽装置の操作コードの安全機構は、図1から図3に示すように、操作コード(ボールチェーン)1の両端に位置する継部2、連結部3を連結する連結部材4は、嵌挿部材5と結合部材6とから構成されている。これら嵌挿部材5と結合部材6とは弾性力のある合成樹脂によって製造されている。この嵌挿部材5には前記操作コード1の継部2を嵌合する空間を備え、操作コード1が貫通する通孔を有する嵌合部5aと内部を中空にして空隙5dを有し、先端が二つに分割されている係合部5bとを備えている。 この嵌挿部材5の係合部5b内は空洞に形成し、この空洞内で上下に摺動する止材7を配置してある。この止材7は金属材料で円筒に作られ、係合部5b内で重力の作用で移動するようになっている。この係合部5bの先端の分割されている先端外周には係止段部5cが突出している。   As shown in FIGS. 1 to 3, the safety mechanism for the operation cord of the solar shading device according to the present invention includes a joint portion 2 positioned at both ends of the operation cord (ball chain) 1 and a connecting member 4 that connects the connecting portions 3. Consists of a fitting member 5 and a coupling member 6. The fitting member 5 and the coupling member 6 are manufactured from a synthetic resin having elasticity. The fitting member 5 has a space for fitting the joint portion 2 of the operation cord 1, has a fitting portion 5 a having a through hole through which the operation cord 1 passes, and a gap 5 d with the inside hollow, Is provided with an engaging portion 5b divided into two. The engaging portion 5b of the fitting member 5 is formed in a cavity, and a stopper 7 that slides up and down in the cavity is disposed. The stopper 7 is made of a metal material in a cylindrical shape, and is moved by the action of gravity in the engaging portion 5b. A locking step 5c projects from the outer periphery of the divided tip of the engaging portion 5b.
一方、結合部材6は嵌挿部材5の先端の係合部5bを嵌挿する外筒6aと操作コード1の連結部3を収納する収納部6bとから構成され、外筒6aには嵌挿部材5の係合部5bの係止段部5cと係合する嵌孔6cが穿ってある。
図4に示す状態、すなわち、結合部材6が下側にあるときは前記係合部5aの止材7は係合部5bの下端に位置し、係止段部5cが外筒6aの嵌孔6cに嵌着している状態を維持するようになっている。しかし、強力な衝撃力が作用したときは係止段部5cが外筒5cの嵌孔6cから抜ける。この止材7は嵌挿部材5の係合部5bの先端の開脚度合いを制御するものである。この係止段部5cの稜線部には傾斜面に形成してある。8は窓枠に取り付けるヘッドボックスであり、この側板9,9にローマンシェードなどの布地10の回転軸が軸支してある。
On the other hand, the coupling member 6 includes an outer cylinder 6a for inserting the engaging portion 5b at the tip of the insertion member 5 and a storage portion 6b for storing the connecting portion 3 of the operation cord 1, and the outer cylinder 6a is inserted into the outer cylinder 6a. A fitting hole 6c that engages with the locking step portion 5c of the engaging portion 5b of the member 5 is formed.
In the state shown in FIG. 4, that is, when the coupling member 6 is on the lower side, the stopper 7 of the engaging portion 5a is located at the lower end of the engaging portion 5b, and the locking step portion 5c is the fitting hole of the outer cylinder 6a. The state fitted to 6c is maintained. However, when a strong impact force is applied, the locking step portion 5c comes out of the fitting hole 6c of the outer cylinder 5c. This stopper 7 controls the degree of leg opening at the tip of the engaging portion 5 b of the fitting member 5. The ridge line portion of the locking step portion 5c is formed on an inclined surface. A head box 8 is attached to the window frame, and the side plates 9 and 9 are supported by a rotation shaft of a fabric 10 such as a roman shade.
本発明の日射遮蔽装置の操作コードの安全機構について、図面に示す操作コードがボールチェーンである実施形態について説明する。
図6に示すように遮蔽部材でありロールスクリーン、布地10などの布地がヘッドボックス8に垂下されて遮蔽状態にあるとき、連結部材4は嵌挿部材5が上側で、結合部材6が下側に位置している。この状態から布地10を上昇させるときは操作コード1の下側を牽引することになるが、嵌挿部材5の係止段部5cが結合部材6の嵌孔6cに嵌着し、抜けない状態である。特に、嵌挿部材5の係合部5b内の下側に止材7が位置しているから係合部5bは収縮し難く、操作コード1は普通に操作されて、布地10は上昇する。
布地10が垂下状態で操作コード1に衝撃力が負荷されたときには嵌挿部材5の嵌合部5aの係合部5b内の止材7が下降して結合部材6の外筒6aの嵌孔6cから係止段部5cが抜け難くなっている。表1に示されるようにこの脱落力は衝撃力が5.5〜6.0Kg以上の力によって操作コード1が引っ張られると係合部5bの係止段部5cが外筒6の嵌孔6cから外れて分離される。これは係合部5cなどがやや弾力性のある合成樹脂で作られているので嵌孔6cから係止段部5cが抜ける。
Regarding the safety mechanism of the operation cord of the solar shading device of the present invention, an embodiment in which the operation cord shown in the drawings is a ball chain will be described.
As shown in FIG. 6, when the cloth such as the roll screen and the cloth 10 is suspended by the head box 8 and is in a shielded state, the connecting member 4 is on the upper side and the coupling member 6 is on the lower side. Is located. When the fabric 10 is raised from this state, the lower side of the operation cord 1 is pulled, but the locking step portion 5c of the insertion member 5 is fitted into the fitting hole 6c of the coupling member 6 and is not removed. It is. In particular, since the stopper 7 is positioned on the lower side in the engaging portion 5b of the fitting member 5, the engaging portion 5b is difficult to contract, the operation cord 1 is normally operated, and the fabric 10 is raised.
When an impact force is applied to the operation cord 1 while the fabric 10 is in the suspended state, the stopper 7 in the engaging portion 5b of the fitting portion 5a of the fitting member 5 is lowered and the fitting hole of the outer cylinder 6a of the coupling member 6 is lowered. The locking step 5c is difficult to come off from 6c. As shown in Table 1, when the operation cord 1 is pulled by a force with an impact force of 5.5 to 6.0 Kg or more, this drop-off force causes the engaging step 5c of the engaging portion 5b to fit into the fitting hole 6c of the outer cylinder 6. Separated from. Since the engaging portion 5c and the like are made of a slightly elastic synthetic resin, the locking step portion 5c comes off from the fitting hole 6c.
次に、図7に示すように布地10が上昇位置にあるときには操作コード1の連結部材4は嵌挿部材5が下側で、結合部材6が上側に位置する。この状態で操作コード1に衝撃力が負荷されたときは結合部材6の外筒6aに係着している嵌挿部材5の係合部5b内の止材7が下降しているので、係合部5bの先端が縮小して係止段部5cが外筒6aの嵌孔6cから抜けることになり、嵌挿部材5と結合部材6との係合は簡単に分離する。
実験によるとこの分離する力は約2.5〜3.2Kgの衝撃で簡易に分離することになった。これは合成樹脂のような可撓性を有する材質で製造されているから係合部5bの先端が容易に狭まる。
操作するときは下側操作コード1の両端に配置した継部2と連結部3がそれぞれ連結部材4の嵌挿部材5の嵌合部5aと結合部材6の収納部6aに嵌合してある。
Next, as shown in FIG. 7, when the fabric 10 is in the raised position, the connecting member 4 of the operation cord 1 has the fitting member 5 on the lower side and the coupling member 6 on the upper side. When an impact force is applied to the operation cord 1 in this state, the stopper 7 in the engaging portion 5b of the fitting member 5 that is engaged with the outer cylinder 6a of the coupling member 6 is lowered. The front end of the joint portion 5b is reduced and the locking step portion 5c is removed from the fitting hole 6c of the outer cylinder 6a, and the engagement between the fitting member 5 and the coupling member 6 is easily separated.
According to experiments, this separation force was easily separated with an impact of about 2.5 to 3.2 kg. Since this is made of a flexible material such as synthetic resin, the tip of the engaging portion 5b is easily narrowed.
When operating, the joint portion 2 and the connecting portion 3 arranged at both ends of the lower operation cord 1 are fitted into the fitting portion 5a of the fitting member 5 of the connecting member 4 and the storage portion 6a of the coupling member 6, respectively. .
(実験例)
本発明の操作コードの連結部材について、遮蔽部材であるカーテンが上昇位置にあるときの連結部材の位置、すなわち図7に示す状態のときの引っ張ったときの抜ける力を測定した。1回目は抜け難いが、2〜10回では抜け易くなっている。また、図6に示すようにカーテンが降下した状態のとき、すなわち抜けない方向のときの平均値は5.8Kgであった。従って、カーテンの昇降操作には支障がなかった。
(Experimental example)
With respect to the connecting member of the operation cord of the present invention, the position of the connecting member when the curtain as the shielding member is in the raised position, that is, the pulling force when pulled in the state shown in FIG. 7 was measured. It is difficult to come off the first time, but it is easy to come off 2 to 10 times. Further, as shown in FIG. 6, the average value when the curtain was lowered, that is, the direction in which the curtain was not removed was 5.8 kg. Therefore, there was no hindrance to the raising and lowering operation of the curtain.
以上のように本発明の安全機構は、連結部分の構造から操作コード1の操作時には支障なく布地10を昇降することができる。他方強い衝撃力が負荷されたときは簡単に連結部分が分離するので安全である。   As described above, the safety mechanism of the present invention can raise and lower the fabric 10 without any trouble when the operation cord 1 is operated from the structure of the connecting portion.
